Description

Technical Field

[0001] The utility model belongs to the technical field of evaporator cleaning, and particularly relates to an automatic cleaning device for a vehicle air conditioner evaporator. Background Technique

[0002] The automotive air conditioner evaporator is an important component in the automotive air conditioning system. Its main function is to vaporize the liquid refrigerant at low pressure and low temperature, absorb the surrounding heat, so as to achieve the refrigeration effect. During the vaporization process, it will absorb a large amount of surrounding heat, and the low-temperature and low-pressure refrigerant vapor is inhaled into the compressor, and so on in a cycle to achieve the purpose of refrigeration;

[0003] At present, after the vehicle air conditioner has been used for a period of time, the air conditioner has a relatively strong odor. Replacing the filter screen or cleaning the air conditioner pipeline has little effect; the fundamental reason is that a large amount of condensed water will be generated when the evaporator evaporates and absorbs heat, resulting in a layer of water remaining on the surface. Since dust will enter the evaporator and adhere to it when the air conditioner works, mildew will occur after a long time, and this position is very difficult to clean. Ordinary blowing with a blower cannot remove the mildew, so the odor in the vehicle will become more and more serious;

[0004] To solve the above problems, an automatic cleaning device for a vehicle air conditioner evaporator is proposed in this application. Content of the Utility Model

[0005] The purpose of the utility model is to provide an automatic cleaning device for a vehicle air conditioner evaporator, which solves the problems raised in the above background technique.

[0007] The utility model is an automatic cleaning device for a vehicle air conditioner evaporator, including: a box body and the evaporator inside it; a water tank is installed through the space reserved during the assembly of the air conditioner box to store the cleaning liquid. A conduit is provided inside the box body, and nozzles are equidistantly arranged on one side of the conduit; a storage tank, a blower, and a water pump are also installed inside the space reserved during the assembly of the air conditioner box, which cooperate with the water tank to form a sufficient cleaning operation to remove mildew impurities.

[0008] Further, one end of the conduit is provided with a rotary joint, which is installed outside the upper end of the box body.

[0009] Further, the blower, the water tank, and the storage tank are respectively installed with a first diversion pipe, a second diversion pipe, and a third diversion pipe on the outside, which release the cleaning reagent, the cleaning liquid, and the wind in sequence, and cooperate with each other to form a multi-stage cleaning effect.

[0010] Further, a double-pass pipe is provided outside the rotary joint to connect the first diversion pipe, the second diversion pipe, and the third diversion pipe.

[0011] Further, a control valve for controlling the passage state is provided on one side of the double-pass tube.

[0012] Further, an induction valve is provided at one end of the storage tank to dock with the third diversion tube.

[0013] Further, the cleaning assembly and the air-conditioning box are assembled together with the vehicle, matched with the layout, and when in use, press the special switch to automatically perform the cleaning work.

[0014] The utility model has the following beneficial effects:

[0015] By adding a conduit and a nozzle, the utility model can start the water pump after the evaporator has been used for a certain period of time, pump out water to spray and wash the evaporator, so as to carry away mildew substances and remove the peculiar smell in the vehicle. Compared with the existing cleaning methods, the equipment can reuse the resources invested at one time, and the operation is simple and convenient for the car owner to clean and use by himself;

[0016] When the utility model cleans the evaporator, a cleaning reactant can be applied to its surface in advance through the storage tank, and then, with the cooperation of the water tank and the water pump, double operations of spraying water and spraying air are carried out to effectively remove impurities such as mildew, achieving a sufficient cleaning effect and improving the subsequent operation quality of the evaporator.
