Problems solved by technology

[0004] However, for air conditioners that can only cool, such as single-cooling air conditioners and air conditioners that have failed heating functions, they can only rely on manual scrubbing of the heat exchanger to clean the dirt and bacteria attached to the surface of the heat exchanger, which is time-consuming and laborious

Embodiment 1

[0031] Such as figure 1 As shown, a heat exchanger self-cleaning device includes a heating device arranged below the heat exchanger and a collecting device arranged below the heating device. A fan is also provided below the heating device. In the first embodiment, the heat exchange The evaporator 1 is used as the device, and the cross-flow fan 2 is used as the fan.

[0032] The heating device adopts PTC heater 3. The PTC heater 3 has the advantages of small thermal resistance, high heat transfer efficiency, and high safety, and is an electric heater with automatic constant temperature and power saving.

[0033] The PTC heater 3 is connected to the evaporator 1 through the connection plate 4, specifically: one end of the connection plate 4 is fixed to the PTC heater 3 by a fastener, and the end of the connection plate 4 away from the PTC heater 3 is fixed to the evaporator 1, and In the first embodiment, the fasteners are screws or bolts. By using fasteners to fix the connec...

Embodiment 2

[0043] In the first embodiment, since the defrosting water that takes away the dirt and bacteria on the surface of the evaporator 1 has become sewage, and the sewage remains in the liquid receiving tray 6, when the sewage in the liquid receiving tray 6 is full, the user needs to remove the The liquid pan 6 is removed, and the sewage in the liquid pan 6 is poured out and reinstalled on the lower end of the deflector 5 . Therefore, it can be known from the sewage treatment process that it is inconvenient to clean the liquid receiving tray 6 .

[0044] For this, if figure 1 As shown, the present embodiment 2 is based on the embodiment 1. In the heat exchanger self-cleaning device of the present embodiment 2, the liquid receiving pan 6 communicates with the outside through the discharge pipe 7, and the discharge pipe 7 is provided with a valve. 8.

[0045] The specific use process is:

[0046] When it is necessary to clean the dirt and bacteria on the evaporator 1, adjust the a...

Embodiment 3

[0051] The third embodiment is the same as the second embodiment, the difference is that in the self-cleaning device for heat exchangers in the third embodiment, the surface of the PTC heater 3 is welded and fixed with a plurality of fins 9 side by side, two adjacent The pitch of fins 9 is 4-5mm, preferably, the pitch of two adjacent fins 9 is 4.5mm, when the pitch of two adjacent fins 9 is 4.5mm, it is the adjacent two of evaporator 1 3 times the pitch of the fins, which can prevent the PTC heater 3 from impacting the cold output of the evaporator 1.

[0052] By providing the fins 9 , the PTC heater 3 can generate heat evenly, and can quickly and evenly melt the frost formed on the evaporator 1 , thus improving the efficiency of the defrosting water to remove dirt and bacteria on the evaporator 1 .

Abstract

The invention discloses a heat exchanger self-cleaning device and an air conditioner, which relate to the technical field of air conditioner cleaning devices. The heat exchanger self-cleaning device comprises a heating device arranged below the heat exchanger and a collecting device arranged below the heating device, the heating device is connected with the heat exchanger, and the collecting device is connected with the heating device. The air conditioner comprises the heat exchanger, and the heat exchanger self-cleaning device is arranged on the heat exchanger. Self-cleaning of the heat exchanger of the air conditioner only capable of refrigerating can be achieved, two hands are liberated, and time and labor are saved; and the use and maintenance of the user are facilitated, and the use experience of the user is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioner cleaning devices, in particular to a heat exchanger self-cleaning device and an air conditioner. Background technique [0002] With the long-term use of the air conditioner, dust and other dirt are easy to adhere to the heat exchanger of the air conditioner. If the dirt is not cleaned in time, the dirt will become moldy and breed bacteria, which will endanger the health of users. Especially in areas with high temperature and high humidity, it is easier to attach dirt and bacteria to the heat exchanger. [0003] For an air conditioner that can both cool and heat, you can first adjust the air conditioner to the cooling mode. At this time, the heat exchanger works as an evaporator to condense a layer of frost on the surface of the heat exchanger; then adjust the air conditioner to the heating mode , at this time, the heat exchanger works as a condenser to melt the frost condensed on the surf...
