Abstract

An air conditioner indoor unit is provided. The air conditioner indoor unit includes: a base module, having a base part which is arranged with a fan motor; a heat exchange module having a heat exchanger and a connection pipeline for connecting the heat exchanger to an air conditioner outdoor unit; the heat exchanger and the connection pipeline are arranged in such a way that in a mounted state, the heat exchanger and the connection pipeline are entirely located at a front side of the base module; an air and water duct module having an air duct assembly; the air duct assembly is suitable to be entirely disassembled from the base part without disassembling the fan motor in the base part. During mounting, pre-assembly is first performed and then general assembly is performed; in such manner, the time needed to assemble the whole unit may be reduced.

First claim

What is claimed is:

1. An air conditioner indoor unit, comprising:
a base module, having a base part which is arranged with a fan motor;
a heat exchange module having a heat exchanger and a connection pipeline for connecting the heat exchanger to an air conditioner outdoor unit; the heat exchanger and the connection pipeline are arranged in such a way that in a mounted state, the heat exchanger and the connection pipeline are entirely located at a front side of the base module; and
an air and water duct module having an air duct assembly; the air duct assembly is suitable to be entirely disassembled from the base part without disassembling the fan motor in the base part, the air and water duct module has a bottom shell and an impeller which is rotationally mounted on the bottom shell; an impeller shaft of the impeller is suitable to be, by means of a quick release connecting structure, connected with and separated from an output shaft of the fan motor through a position movement between the impeller shaft and the output shaft, the quick release connecting structure comprises a clamping groove formed in the impeller shaft of the impeller and a clamping claw arranged on the output shaft of the fan motor and mating with the clamping groove,
at the working position of the fan motor, the clamping claw is arranged in the clamping groove and the output shaft rotates to drive the impeller shaft to rotate, the clamping claw is a helical clamping claw, and the clamping groove is a helical clamping groove, so that the output shaft rotate at the working position of the fan motor to make the helical clamping claw and the helical clamping groove get close to each other under the action of helical surfaces of the helical clamping groove and the helical clamping claw,
at the quick release position of the fan motor, when the fan motor is disassembled after the fan motor is unlocked, the clamping claw is separated from the clamping groove.

2. The air conditioner indoor unit as claimed in claim 1 , wherein the heat exchange module and the air and water duct module are movably mounted on the base part respectively.

3. The air conditioner indoor unit as claimed in claim 1 , further comprising:
an exterior module, having an air guide module detachably mounted on the base module, an air outlet frame module detachably mounted on the base module and/or the air and water duct module, and a shell module detachably mounted on the base module; and
an electric assembly, having an electrical box, an air guide poking box, and the fan motor for poking an impeller to rotate.

4. The air conditioner indoor unit as claimed in claim 3 , wherein the shell module is detachably mounted on the base module, and comprises a panel body, and a filter screen and a panel which are detachably mounted on the panel body.

5. A method for assembling an air conditioner indoor unit, comprising:
a. pre-assembling in the base module, the air and water duct module, the heat exchange module, the air outlet frame module and the air guide module as claimed in claim 4 on a corresponding pre-assembly line, so that the base module, the air and water duct module, the heat exchange module, the air outlet frame module and the air guide module form five independent pre-assembly modules respectively;
b. on a general assembly line, taking the base module as an assembling basis, respectively assembling the heat exchange module and the air and water duct module with the base module at first;
c. assembling a panel body of a shell module as claimed in claim 4 with the base module, and assembling a filter screen of the shell module with the panel body; then, assembling the air outlet frame module with the base module, and assembling the panel with the panel body;

6. The air conditioner indoor unit as claimed in claim 3 , wherein the electric assembly is detachably mounted on the base part of the base module, or detachably mounted on the bottom shell of the air and water duct module.

7. The air conditioner indoor unit as claimed in claim 6 , wherein the base module comprises a motor bracket fixed on the base part; the motor bracket comprises:
a motor stand; and
a motor pressure plate and a motor cover plate which are mounted on the motor stand and configured to fix the fan motor;
wherein the motor pressure plate and the motor cover plate are detachably mounted on the base part respectively;
the motor pressure plate limits the fan motor in a radial direction, and the motor cover plate limits the fan motor in an axial direction.

8. The air conditioner indoor unit as claimed in claim 6 , wherein the electric assembly further comprises a concentrator; a load terminal of the air conditioner indoor unit is electrically connected with the concentrator; the concentrator is electrically connected with the electrical box, the concentrator comprise a patch panel and a mounting matrix, the patch panel is mounted on the mounting matrix, the load terminal is arranged on the patch panel.

9. The air conditioner indoor unit as claimed in claim 6 , wherein the electric assembly is detachably mounted on an end of the base part or an end of the bottom shell.

10. The air conditioner indoor unit as claimed in claim 3 , wherein the shell module is detachably mounted on the base module, and comprises:
a panel body; and
a filter screen and a panel which are detachably mounted on the panel body;
wherein the panel body comprises a mounting rack, and two side panels which are detachably mounted on two ends of the mounting rack and correspond to the two ends of the base part.

11. The air conditioner indoor unit as claimed in claim 3 , wherein the shell module is detachably mounted on the base module through a buckle structure.

12. The air conditioner indoor unit as claimed in claim 11 , wherein the air and water duct module is mounted on the base module in a sliding manner through a first guide structure, and performs limiting locking to a mounting state through the buckle structure and a threaded connecting piece;
