Abstract

A fan, in particular an axial fan, comprising a support element with a wall ring and an electric fan motor which is mounted in the wall ring and comprises a fan rotor. The wall ring has on its outer periphery a hinge consisting of a first hinge part that is connected to the wall ring and a second hinge part that can be pivoted about a hinge axis relative to the first hinge part, wherein the second hinge part is designed as a terminal box for receiving electrical connectors. The invention further relates to a support element for such a fan.

First claim

The invention claimed is:

1. A fan, comprising:
a support element having a wall ring; and
an electric fan motor mounted in the wall ring, having a fan rotor,
wherein the wall ring has a hinge on its outside circumference, which hinge consists of a first hinge part firmly connected with the wall ring and a second hinge part that can pivot relative to the first hinge part, about a hinge axis (X), wherein the second hinge part is configured as a terminal box, wherein the terminal box is mounted outside of the wall ring and contains connectors, and wherein the two hinge parts have bearing accommodations that align with one another in the direction of the hinge axis, on the one hand, and bearing journals, on the other hand, which are joined together in a joining direction that lies perpendicular to the hinge axis (X).

2. A fan according to claim 1 , wherein the hinge axis (X) runs as a tangent to the wall ring, or offset outward parallel to a tangent to the wall ring, and in a ring plane defined by the wall ring and wherein said terminal box is positioned on an opposite side of the hinge axis than the electric fan motor and wherein said connectors are disposed in a region separate from said electric fan motor.

3. A fan according to claim 1 , wherein the first hinge part is connected in one piece with the wall ring and wherein said second hinge part is disposed adjacent to, and outside of a region of said wall ring.

4. A fan according to claim 1 , wherein the bearing accommodations are configured as open bearing shells, in accordance with the joining direction.

5. A fan according to claim 1 , wherein the second hinge part has multiple journal extensions extending perpendicular to the hinge axis (X), each having two opposite axial bearing journals, wherein each journal extension engages, in gear-like manner, between two accommodation extensions of the first hinge part, and, with its bearing journals, into opposite bearing accommodations of the accommodation extensions.

6. A fan according to claim 1 , wherein the second hinge part additionally overlaps with axial bearing journals of the first hinge part with bearing accommodations.

7. A fan according to claim 1 , wherein the joined hinge parts are fixed in place to prevent them from coming loose, by way of engagement means.

8. A fan according to claim 1 , wherein the hinge parts can be joined together and separated only in a defined relative pivot position.

9. A fan according to claim 1 , wherein the wall ring can be attached to an installation wall in the region of a wall opening, for which purpose the wall ring preferably has an outer flangelike holding section with installation holes.

10. A fan according to claim 1 , wherein the second hinge part can be attached on an installation wall in the region next to a wall opening, for which purpose the terminal box has installation holes in the region of a bottom.

11. A fan according to claim 1 , wherein the wall ring, in the circumference direction, has at least one cable introduction opening.

12. The fan according to claim 11 , wherein the wall ring, in a center region of the first hinge part, in the circumference direction, has at least one cable introduction opening.

13. A fan according to claim 1 , wherein the second hinge part is configured in one piece with a bottom box part of the terminal box.

14. A fan according to claim 1 , wherein the terminal box has a box opening that is tightly sealed with a lid and wherein said lid is made of a solid plate configured to prevent air or fluid from passing through.

15. A fan according to claim 14 , wherein the lid has an inner reinforcement ribbing.

16. A fan according to claim 1 , wherein the terminal box has a reduced box depth, by way of a slanted surface, in its front side region facing the hinge.

17. Support element for a fan according to claim 1 , having a wall ring for accommodation of a fan motor, wherein the wall ring has a hinge on its outside circumference, which hinge consists of a first hinge part firmly connected with the wall ring and a second hinge part that can pivot relative to the first hinge part, about a hinge axis (X), wherein the second hinge part is configured as a terminal box for accommodation of electrical connectors.

18. Support element according to claim 17 , wherein the fan is an axial fan comprising:
a support element;
a wall ring; and
an electric fan motor mounted in the wall ring, the motor having a fan rotor, wherein the wall ring has a hinge on its outside circumference,
which hinge consists of a first hinge part firmly connected with the wall ring and a second hinge part that can pivot relative to the first hinge part, about a hinge axis (X), wherein the second hinge part is configured as a terminal box for accommodation of electrical connectors, and wherein the two hinge parts have bearing accommodations that align with one another in the direction of the hinge axis (X), on the one hand, and bearing journals, on the other hand, which are joined together in a joining direction that lies perpendicular to the hinge axis (X) wherein the hinge axis (X) runs as a tangent to the wall ring, or offset outward parallel to a tangent to the wall ring, and in a ring plane defined by the wall ring.

19. The support element as in claim 17 , wherein with respect to the fan, the first hinge part is connected in one piece with the wall ring, and the bearing accommodations are configured as open bearing shells, in accordance with the joining direction.

20. The support element as in claim 19 , wherein with respect to the fan, the second hinge part has multiple journal extensions extending perpendicular to the hinge axis (X), each having two opposite axial bearing journals, wherein each journal extension engages, in gear-like manner, between two accommodation extensions of the first hinge part, and, with its bearing journals, into opposite bearing accommodations of the accommodation extensions;
wherein the second hinge part additionally overlaps with axial bearing journals of the first hinge part with bearing accommodations; wherein the joined hinge parts are fixed in place to prevent them from coming loose, by way of engagement means; and wherein the hinge parts can be joined together and separated only in a defined relative pivot position.

21. A fan, comprising:
a support element having a wall ring; and
an electric fan motor mounted in the wall ring, having a fan rotor,
wherein the wall ring has a hinge on its outside circumference, which hinge consists of a first hinge part firmly connected with the wall ring and a second hinge part that can pivot relative to the first hinge part, about a hinge axis (X), wherein the second hinge part is configured as a terminal box, wherein the terminal box is mounted outside of the wall ring and contains for accommodation of electrical connectors, and wherein the two hinge parts have bearing accommodations that align with one another in the direction of the hinge axis, on the one hand, and bearing journals, on the other hand, which are joined together in a joining direction that lies perpendicular to the hinge axis (X),
wherein the hinge axis (X) runs as a tangent to the wall ring, or offset outward parallel to a tangent to the wall ring, and in a ring plane defined by the wall ring and wherein said terminal box is positioned on an opposite side of the hinge axis than the electric fan motor and wherein said connectors are disposed in a region separate from said electric fan motor.
