Description

Technical Field

[0001] The utility model relates to the technical field of automobile air conditioners, in particular to a protective air conditioner evaporator for automobiles. Background Art

[0002] The automobile evaporator is an important component in the automobile air-conditioning refrigeration system. The evaporator is a heat exchanger. The high-pressure liquid refrigerant enters the evaporator through the expansion valve. Due to the atomization effect of the expansion valve, the liquid refrigerant becomes mist. The mist refrigerant is converted into gas under low-pressure conditions. It absorbs heat during the conversion process, so the evaporator is cool at this time. After the hot air passes through the evaporator, it becomes cool air, achieving the purpose of refrigeration.

[0003] The automobile evaporator is set in the outer shell, which is the channel connecting the cab and the outside world. The outer shell is equipped with a blower, a filter element, an evaporator and a heater from the outside to the inside. When the air conditioner is used in summer, the evaporator works, and the blower transmits the hot air from the outside to the filter element through the outer shell. The filtered air is then cooled by the evaporator and transmitted to the cab to achieve the cooling function in the cab. Although a filter element is set on the outside of the evaporator body, if the filter element is not replaced for a long time, there will still be some debris passing through the filter element. The condensed water generated on the evaporator body when the high temperature meets the low temperature is easy to combine with the debris and the condensed water, so that the muddy water produced adheres to the surface of the evaporator body, which will not only cause poor ventilation and affect the heat exchange effect, but also breed bacteria, causing mold and producing an unpleasant odor in the cab.

[0004] In order to solve the problem of sticking debris, the existing automobile evaporator is provided with a circular roller brush that moves up and down on one side of the evaporator body. Although the arrangement of the circular roller brush can clean the debris on the surface of the evaporator body to a certain extent, the working principle of the circular roller brush is that the motor drives the threaded rod to rotate, and when the threaded rod rotates, the threaded block that cooperates with the threaded rod moves to realize the movement of the circular roller brush. The working principle is relatively complicated. The evaporator body itself is arranged in a narrow outer shell. If the above structure for cleaning debris is arranged in the outer shell, firstly, the strong wind speed is likely to cause damage to the small structure. Secondly, it is not easy to install in a narrow space, and it is easy to cause the problem of poor cleaning effect. Utility Model Content

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] like Figure 1-4 As shown, a protective air conditioning evaporator for automobile includes an evaporator body 1, combined with Figure 1 , Figure 2 and Figure 3 As shown, an air inlet pipe 2 is provided at an upper part of one side of the evaporator body 1, and the air inlet pipe 2 is connected to one end of an external air-conditioning compressor. An air outlet pipe 3 is provided at a lower part of the same side of the evaporator body 1, and the air outlet pipe 3 is connected to the other end of the external air-conditioning compressor. Retaining blocks 5 are provided at four corners of one side of the air inlet of the evaporator body 1, and the bracket 4 is fixed to the evaporator body 1 through the retaining blocks 5. Preferably, the setting of the retaining blocks 5 can keep a certain distance between the evaporator body 1 and the bracket 4, combined with Figure 3 and Figure 4 As shown, a rotating body 6 is rotatably arranged on the bracket 4, a plurality of fan blades 7 are arranged on the circumference of the rotating body 6, a protrusion 8 is arranged on the rotating body 6 and on one side close to the evaporator body 1, and a cleaning component for cleaning the evaporator body 1 is arranged on the protrusion 8.

[0020] Specifically in this embodiment, combined with Figure 3 and Figure 4 As shown, the cleaning component includes a plurality of brush handles 9. Preferably, in order to improve the stability of the brush handles 9 on the raised portion 8, the number of the brush handles 9 is set to be more than three, and the plurality of brush handles 9 are fixedly arranged on the circumference of the raised portion 8. A plurality of bristles 10 in contact with the evaporator body 1 are arranged on the brush handle 9 and on one side close to the evaporator body 1. Preferably, the bristles 10 are soft. When in use, the blower transmits the external wind through the fan blades 7 to the evaporator body 1. When the wind passes through the fan blades 7, the fan blades 7 and the rotation 6 rotate on the bracket 4. When the rotating body 6 rotates, it drives the cleaning component to rotate. When the cleaning component rotates, it contacts the surface of the evaporator body 1, and can brush off the debris and condensed water on the surface of the evaporator body 1, thereby completing the function of cleaning the evaporator body 1. The cleaning component has a simple structure, is not easy to be damaged, is easy to install, and improves the cleaning effect.

[0021] Working principle:

[0022] When the air conditioner is turned on in summer, the evaporator body 1 starts to work, and the outermost blower passes the outside air to the filter element. The air is filtered by the filter element and then passed to the evaporator body 1 through the fan blades 7. When strong air passes through the fan blades 7, the fan blades 7 and the rotating body 6 rotate on the bracket 4. When the rotating body 6 rotates, it drives the protrusion 8 and the brush handle 9 to rotate. When the brush handle 9 rotates, the bristles 10 on the brush handle 9 rub against the surface of the evaporator body 1, and the condensed water on the evaporator body 1 and the debris that has not been filtered out by the filter element are brushed off from the evaporator body 1, thereby completing the function of cleaning the evaporator body 1. When the fan blades 7 rotate, the flow rate of the air in the outer shell can be increased, thereby improving the cooling effect.
