Abstract

A sliding door has a door main body and door support sections supported by contact with an inner wall of a guide groove. The guide groove has a groove lacking section having a size that the door main body can be inserted therefrom. When a first one of the door support sections that is the closest to a tip end of the sliding door is located within the groove lacking section, another one of the door support sections that is located opposite from the tip end of the sliding door through the groove lacking section satisfies a relational expression of A≤90−0.2L, in which A represents a distance from the tip end to an end of the another one of the door support sections on a separated side away from the tip end, and L represents a door width of the door main body.

First claim

The invention claimed is:

1. An air conditioning device comprising:
an air conditioning case that has an opening through which air passes;
a sliding door arranged in the air conditioning case to control an opening area of the opening; and
a guide groove provided in an inner wall surface of the air conditioning case to support an end of the sliding door and to guide a movement of the sliding door, wherein
the sliding door has:
a door main body in a planar shape that is thinner than a groove width of the guide groove; and
a plurality of door support sections provided along a door moving direction at an end of the door main body in a door width direction, the plurality of door support sections being supported by the guide groove by contact with an inner wall of the guide groove,

the guide groove has a groove lacking section in an intermediate portion in the door moving direction, the groove lacking section being in such a size that the door main body can be inserted therefrom,
when a first one of the door support sections that is the closest to a tip end of the sliding door in the door moving direction is located within the groove lacking section, another one of the door support sections that is located opposite from the tip end of the sliding door through the groove lacking section in the guide groove and that is the closest to the groove lacking section satisfies a relational expression of A≤90−0.2L, wherein A (unit: mm) represents a distance from the tip end of the sliding door to an end of the another one of the door support sections, which is the closest to the groove lacking section, on a separated side away from the tip end, and L (unit: mm) represents a door width of the door main body,
when the first one of the plurality of door support sections is located within the groove lacking section, an entire range of a contact portion of the first door support section that comes in contact with the guide groove is located within the groove lacking section such that the first door support section is not supported by the guide groove, and
when the another one of the plurality of door support sections is located on the side that is farther separated from the tip of the door than the groove lacking section in the guide groove, at least a portion of a contact portion of the another one of the door support sections that comes in contact with the guide groove is located within the guide groove such that the another one of the door support sections is supported by the guide groove.

2. The air conditioning device according to claim 1 , wherein
the relational expression is set as a first relational expression, and
a second relational expression of D≤2(90−0.2L) is further satisfied, wherein D (unit: mm) represents a distance between ends on separated sides from each other of two of the door support sections located the closest to the groove lacking section on sides that are one side in the door moving direction and the other side in the door moving direction of the groove lacking section in the guide groove, when the another one of the door support sections is located within the groove lacking section, and L (unit: mm) represents the door width of the door main body.

3. The air conditioning device according to claim 1 , wherein, when a distance between ends on separated sides from each other of two of the door support sections adjacent to each other in the door moving direction is defined as C (unit: mm), and when a length of the groove lacking section in the door moving direction is defined as B (unit: mm), the door support sections are arranged to satisfy C≥B.

4. The air conditioning device according to claim 1 , wherein
the guide groove includes a projection wall projected from the inner wall surface of the air conditioning case and an opposing wall that opposes the projection wall.

5. The air conditioning device according to claim 1 , wherein the sliding door is supported by the guide groove in a state of being bent and deformed.

6. The air conditioning device according to claim 1 , wherein
the plurality of door support sections each demonstrating elastic properties, and
the sliding door is supported by the guide groove with elastic forces of the door support sections.

7. The air conditioning device according to claim 1 , wherein
the sliding door further includes a driven gear extending continuously along and parallel with the door moving direction, and located inward of the plurality of door support sections in the door width direction.

8. The air conditioning device according to claim 1 , wherein
the groove lacking section is located in an upper portion of the guide groove in the door moving direction.

9. The air conditioning device according to claim 1 , wherein
the groove lacking section is defined by an upper wall extending at an angle from the guide groove and a lower wall extending at an angle from the guide groove, the upper wall and the lower wall being parallel to each other.

10. An air conditioning device comprising:
an air conditioning case that has an opening through which air passes;
a sliding door arranged in the air conditioning case to control an opening area of the opening; and
a guide groove provided in an inner wall surface of the air conditioning case to support an end of the sliding door and to guide a movement of the sliding door, wherein
the sliding door has:
a door main body in a planar shape that is thinner than a groove width of the guide groove; and
a plurality of door support sections provided along a door moving direction at an end of the door main body in a door width direction, the plurality of door support sections being supported by the guide groove by contact with an inner wall of the guide groove,

the guide groove has a groove lacking section in an intermediate portion in the door moving direction, the groove lacking section being in such a size that the door main body can be inserted therefrom,
a relational expression of D≤2(90−0.2L) is satisfied, wherein D (unit: mm) represents a distance between ends on separated sides from each other of two of the door support sections located the closest to the groove lacking section on sides that are one side in the door moving direction and the other side in the door moving direction of the groove lacking section in the guide groove, when another one of the door support sections is located within the groove lacking section, and L (unit: mm) represents a door width of the door main body,
when a first one of the plurality of door support sections is located within the groove lacking section, an entire range of a contact portion of the first door support section that comes in contact with the guide groove is located within the groove lacking section such that the first door support section is not supported by the guide groove, and
when the another one of the plurality of door support sections is located on the side that is farther separated from a tip of the door than the groove lacking section in the guide groove, at least a portion of a contact portion of the another one of the door support sections that comes in contact with the guide groove is located within the guide groove such that the another one of the door support sections is supported by the guide groove.

11. The air conditioning device according to claim 10 , wherein, when a distance between ends on separated sides from each other of two of the door support sections adjacent to each other in the door moving direction is defined as C (unit: mm), and when a length of the groove lacking section in the door moving direction is defined as B (unit: mm), the door support sections are arranged to satisfy C≥B.
