Description

Technical Field

[0001] The utility model relates to the field of heat pump air conditioners, in particular to a heat pump air conditioner and an outer top buckle structure of an air guide door thereof. Background Art

[0002] The external air guide door plays a big role in measuring the overall aesthetics of a household air conditioner. After the line body is installed, it is packed by the line body workers and transported to the user's home. During the transportation process, it is inevitable that there will be different degrees of shaking and bumping. As a result, the external air guide door cannot be completely closed and the whole thing collapses.

[0003] At present, the closing method of the external air guide door is to achieve a fully closed state by using the motor self-locking method. However, the motor self-locking method is to achieve the limit effect by gear meshing. This limit method will fail and slip due to the vibration during transportation. When it is delivered to the customer's home or participated in a large-scale exhibition, the external air guide door cannot maintain a fully closed assembly state, the original state of the machine is poor, and the air guide door is deformed, scratched and damaged.

[0004] When the user is away from home for a long time or not in use, the outer air guide door will be deformed by humidity, temperature and other conditions due to its long size and soft texture. If the deformation is large, it will affect the normal use of the air guide door.

[0005] In addition, the outer air guide door itself is relatively long, and pre-deformation tooling is added during the production process to meet the use conditions. And because the material is relatively soft, the rebound is difficult to control and it is easy to deform and damage during transportation. Utility Model Content

[0006] In order to solve the problem that the outer air guide door is easy to deform in the prior art, the purpose of the utility model is to provide a heat pump air conditioner and its air guide door outer top buckle structure to prevent the outer air guide door from deforming due to gravity, reduce the pressure of motor self-locking, and extend the service life of the motor.

[0007] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: an air guide door outer top buckle structure, comprising a middle frame, a base and an air guide door, the base is fixed in the middle frame, the air guide door is rotatably installed on the base, a limiting space is set between the air guide door and the middle frame, a first connecting part and a second connecting part are raised on the base, a first clamping groove is opened on the first connecting part, and a second clamping groove is set on the second connecting part;

[0008] The outer top buckle comprises a base body, a first limiting portion and a second limiting portion are protruded from the base body, a first clamping protrusion is protruded from the first limiting portion, and a second clamping protrusion is arranged on the second limiting portion;

[0009] When the outer top buckle is connected to the middle frame, the base is inserted into the gap between the air guide door and the middle frame, the air guide door and the middle frame are both abutted against the base, the first clamping protrusion on the outer top buckle is clamped with the first clamping groove of the base, and the second clamping protrusion of the outer top buckle is clamped with the second clamping groove of the base.

[0010] Preferably, the first limiting portion protrudes on two symmetrically arranged connectors, and two second clips are respectively arranged on the two connectors, and the second clips are located between the two connectors; the first connecting portion of the base is inserted between the two connectors, and the two first clips are respectively inserted into the first slot from both sides of the first slot.

[0011] Preferably, an avoidance groove is provided on the first limiting portion, and the avoidance groove is located between the two connectors.

[0012] Preferably, the second limiting portion of the outer top buckle is located between the first connecting portion and the second connecting portion of the base.

[0013] Preferably, the base is arc-shaped.

[0014] Preferably, a handle is protruded from the base, and the handle and the limiting part are arranged on two opposite side surfaces of the base.

[0015] Preferably, the end of the handle is provided with two symmetrically arranged arc-shaped pulling parts.

[0016] Preferably, the first limiting portion is arranged at a middle position of the base, and the first connecting portion is arranged at a middle position of the base.

[0017] Preferably, the second limiting portion is disposed at the end of the base body, and the second connecting portion is disposed at the end of the base body.

[0018] A heat pump air conditioner comprises the above-mentioned air guide door outer top buckle structure.

[0019] The beneficial effects of the technical solution of the utility model are as follows: the outer top buckle can be inserted and removed between the air guide door and the middle frame by plugging and pulling. When the user is away from home for a long time or does not use the air conditioner, the outer top buckle of the air guide door can be installed to prevent the outer air guide door from being deformed due to gravity, reduce the pressure of motor self-locking, and extend the service life of the motor; and because the outer top buckle can fill the gap between the middle frame and the air guide door, it can prevent mosquitoes from flying into the air duct when not in use for a long time, thereby ensuring the stability of the internal structure.
