Description

Technical Field

[0001] This disclosure belongs to the field of air conditioning technology, specifically relating to a self-cleaning device and an air conditioner. Background Technology

[0002] Floor-standing air conditioners are increasingly popular due to their high power and strong airflow. However, after a period of use, the indoor heat exchanger of a floor-standing air conditioner tends to attract a lot of dust due to static electricity and other reasons, which affects the cooling and heating performance of the evaporator and makes it easy for bacteria or mold to grow.

[0003] Some related technologies utilize the cooling function to frost the evaporator and then defrost it by heating, thus achieving the effect of cleaning the evaporator fins. However, this method is not very effective and cannot thoroughly clean the evaporator. Summary of the Invention

[0004] Therefore, the technical problem to be solved by this disclosure is that the cleaning effect of the indoor heat exchanger of the cabinet air conditioner is poor, which affects the heat exchange performance of the heat exchanger, thereby providing a self-cleaning device and an air conditioner.

[0005] To address the aforementioned problems, this disclosure provides a self-cleaning device for self-cleaning air conditioners, comprising:

[0006] Heat exchanger;

[0007] A spraying device and a traction module, wherein the spraying device is configured to spray water onto the heat exchanger;

[0008] The air conditioner is equipped with a movable door assembly, and the spray device is connected to the movable door assembly through a traction module. The spray device can move along the extension direction of the heat exchanger under the drive of the movable door assembly.

[0009] The purpose of this disclosure and the technical problems it addresses can be further achieved through the following technical measures.

[0010] In some embodiments, the traction module includes a guide rail and a push rod, and the spraying device is slidably mounted on the guide rail and connected to the movable door assembly via the push rod.

[0011] In some embodiments, a connector is provided between the push rod and the movable door assembly, the connector being configured to controllably connect or disconnect the push rod and the movable door assembly.

[0012] In some embodiments, the connector is an electromagnet assembly.

[0013] In some embodiments, the guide rail is disposed above the heat exchanger in the vertical direction, and the extension direction of the guide rail is the same as the extension direction of the heat exchanger.

[0015] In some embodiments, the movable door assembly includes a door panel and a drive motor, and the air conditioner includes a housing with an air outlet, and the door panel is movably disposed on the air outlet.

[0016] In some embodiments, the spray device includes a water collection tank configured to be able to receive water from the outside and / or to collect condensate from the air conditioner.

[0017] In some embodiments, the sprinkler device further includes a spray head, which is mounted on a traction device via a slider. The spray head is connected to a water collection tank via a hose, and a water pump is provided on the hose.

[0018] In some embodiments, the water pump inlet is connected to the water collection tank and an external water source through a second reversing valve. By controlling the conduction direction of the second reversing valve, the water pump can draw water from the water collection tank or the external water source respectively.

[0019] In some embodiments, the air conditioner is provided with a water receiving tray, the water receiving tray is provided with a water outlet pipe, the water outlet pipe is provided with a first reversing valve, and the first reversing valve is connected to a water collection tank and a drain pipe respectively.

[0030] To make the objectives, technical solutions, and advantages of this disclosure clearer, the technical solutions of this disclosure will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0031] Combination Figures 1 to 4 As shown, this embodiment provides a self-cleaning device for self-cleaning an air conditioner, including: a heat exchanger 1; a spray device 2 and a traction module 3. The spray device 2 is configured to spray water onto the heat exchanger 1. The air conditioner is provided with a movable door assembly 4. The spray device 2 is connected to the movable door assembly 4 through the traction module 3. The spray device 2 can move along the extension direction of the heat exchanger 1 under the drive of the movable door assembly 4.

[0032] The self-cleaning device disclosed herein is installed inside a cabinet air conditioner, enabling the air conditioner to have self-cleaning capabilities. The spray device 2 moves along the extension direction of the heat exchanger 1 under the traction of the traction device, and can spray and clean the heat exchanger 1 repeatedly without dead angles. Compared with the defrosting method, it has the advantages of better cleaning effect and thorough cleaning. At the same time, the movement of the spray device 2 does not require a separate drive device. The spray device 2 is connected to the movable door assembly 4 through the traction module 3, so that the reciprocating movement of the spray device 2 is synchronously driven when the movable door assembly 4 moves, which fully saves the space occupied inside the air conditioner, eliminates a set of drive devices, and saves the product cost of the air conditioner.

[0033] In some embodiments, to enable the spray device 2 to move along the heat exchanger 1 via the movable door assembly 4 of the air conditioner, the traction module 3 includes a guide rail 5 and a push rod 6. The spray device 2 is slidably mounted on the guide rail 5 and connected to the movable door assembly 4 via the push rod 6. When the movable door assembly 4 performs the opening and closing action of the door panel 7, the spray device 2 can slide along the guide rail 5 under the action of the push rod 6, achieving thorough spray cleaning of the heat exchanger 1 without any blind spots.

[0034] In some embodiments, when self-cleaning is not required, the connection between the push rod 6 and the movable door assembly 4 can be disconnected to prevent the movable door assembly 4 from sliding ineffectively with the spray device 2, thereby increasing the opening and closing resistance of the movable door assembly 4 and extending its service life. A connector is provided between the push rod 6 and the movable door assembly 4, and the connector is configured to controllably connect or disconnect the push rod 6 and the movable door assembly 4.

[0035] In some embodiments, the connector is an electromagnet assembly. By controlling the on and off of the current in the electromagnet, the connection or disconnection between the push rod 6 and the movable door assembly 4 is controlled, which facilitates centralized control of the connector by the air conditioner.

[0036] In some embodiments, inside the cabinet air conditioner, the heat exchanger 1 is arranged generally along the vertical direction, and the guide rail 5 is disposed above the heat exchanger 1 along the vertical direction. The extension direction of the guide rail 5 is the same as the extension direction of the heat exchanger 1. By placing the guide rail 5 and its mounted spray device 2 above the heat exchanger 1, the spray water flushes the heat exchanger 1 along the direction of gravity, thereby improving the flushing and cleaning effect of the spray water.

[0037] In some embodiments, particularly circular cabinet units, the heat exchanger 1 extends in an arc shape, the guide rail 5 extends in an arc shape, and the push rod 6 is an arc shape. Due to the special structure of the circular cabinet unit, the movement direction of the movable door assembly 4 is also along an arc trajectory. In this case, the movable door assembly 4, combined with the arc-shaped push rod 6 and the arc-shaped guide rail 5, allows the spray device 2 to slide along the same arc. The sliding direction of the spray device 2 is consistent with the movement trajectory of the movable door assembly 4. The movable door assembly 4 can push the spray device 2 to slide back and forth with a small force, which can improve the reliability of the reciprocating sliding spray of the spray device 2, reduce the burden on the movable door assembly 4, and improve the service life of the movable door assembly 4.

[0038] In some embodiments, the movable door assembly 4 includes a door panel 7 and a drive motor. The air conditioner includes a housing with an air outlet, and the door panel 7 is movably disposed on the air outlet. Thus, the door panel 7 can open and close the air outlet and / or control the airflow direction under the drive of the drive motor. Simultaneously, the drive motor in the movable door assembly 4 provides power for the reciprocating sliding of the spray device 2. The drive motor has at least a dual function, improving its utilization rate.

[0039] In some embodiments, to ensure that the spray device 2 has sufficient spray water to spray the heat exchanger 1, the spray device 2 includes a water collection tank 8, which is configured to be able to receive water from the outside and / or collect condensate from the air conditioner. The water collection tank 8 can recycle the condensate from the air conditioner, which has economic and environmental advantages.

[0040] In some embodiments, to achieve thorough cleaning of the heat exchanger 1 by spraying water without dead angles, the spraying device 2 further includes a spray head 9. The spray head 9 is mounted on a traction device via a slider 10. The spray head 9 is connected to a water collection tank 8 via a hose 11, on which a water pump 12 is mounted. The slider 10 is connected to a push rod 6 and slides on a guide rail 5 as pulled by the push rod 6, thereby enabling the spray head 9 to perform reciprocating, thorough cleaning without dead angles. The hose 11 is designed to reduce the obstruction of the water pipes to the movement of the spray head 9. The water pump 12 provides a stable, sufficient, and pressurized water supply to the spray head 9, improving the spraying effect of the spray head 9.

[0041] In some embodiments, to prevent insufficient water in the water collection tank 8, the inlet of the water pump 12 is connected to both the water collection tank 8 and an external water source via a second reversing valve 13. By controlling the conduction direction of the second reversing valve 13, the water pump 12 can draw water from either the water collection tank 8 or the external water source. When the water in the water collection tank 8 is insufficient, the second reversing valve 13 switches to drawing water from the external water source to ensure sufficient water flow to the spray head 9.

[0042] In some embodiments, the air conditioner is provided with a water collection tray located at the bottom of the heat exchanger 1. The water collection tray collects condensate from the heat exchanger 1 during cooling mode, as well as wastewater generated during self-cleaning. The water collection tray has a drain pipe 15, which is equipped with a first reversing valve 16. The first reversing valve 16 is connected to a water collection tank 8 and a drain pipe 17. The first reversing valve 16 can be controlled such that in cooling mode, it is connected to the water collection tank 8 by default, collecting condensate in the water collection tank 8; while in self-cleaning mode, due to the poor water quality used to flush the heat exchanger 1, wastewater is directly discharged through the drain pipe 17.

[0043] In some embodiments, the water collection tank 8 is disposed below the water receiving tray in the vertical direction. This embodiment places the water collection tank 8 below the water receiving tray, which helps improve the drainage capacity of the water receiving tray and makes full use of the lower space of the air conditioner, thus improving the space utilization rate inside the air conditioner.

[0044] The self-cleaning device disclosed herein is installed inside a circular cabinet air conditioner. Through a simple connection structure, and with the opening and closing drive motor of the door panel 7 as the power source, it achieves reciprocating spraying of the arc-shaped evaporator without dead angles, thereby realizing the self-cleaning of the evaporator of the circular cabinet air conditioner. The sprayed water can utilize the condensate water of the air conditioner, improving the economic and environmental performance of the air conditioner.

[0045] An air conditioner employs the aforementioned self-cleaning device.

[0046] It will be readily understood by those skilled in the art that the aforementioned advantageous methods can be freely combined and superimposed without conflict.

[0047] The above are merely preferred embodiments of this disclosure and are not intended to limit this disclosure. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this disclosure should be included within the protection scope of this disclosure. The above are merely preferred embodiments of this disclosure. It should be noted that those skilled in the art can make several improvements and modifications without departing from the technical principles of this disclosure, and these improvements and modifications should also be considered within the protection scope of this disclosure.
