Description

Technical Field

[0001] The present invention relates to the technical field of automobile air conditioners, and in particular to an evaporator for an automobile air conditioner. Background Art

[0002] The working principle of the automotive air conditioning evaporator is based on the phenomenon of evaporation heat absorption in physics. When the low-temperature, low-pressure liquid refrigerant flows into the evaporator from the expansion valve, its temperature and pressure begin to decrease. The liquid refrigerant absorbs the heat of the surrounding air inside the evaporator and evaporates into gas. This process requires the absorption of a large amount of heat, including the heat of the evaporator itself and the surrounding air, to achieve a cooling effect.

[0003] In the patent entitled "An Evaporator for Automobile Air Conditioning" and with the authorization number of CN110553426B, it is proposed that in the prior art, a large amount of fine dust contained in the air flow will accumulate on the shutter fins of the automobile evaporator, and the dust will clog and corrode the shutter fins, affecting the working efficiency of the evaporator. The air inlet and outlet components control the air inlet and outlet of several air inlet slots. After the evaporator body has worked for a certain period of time, the evaporator body stops working. At this time, the air inlet and outlet components work to prevent the outside air flow from passing through several air inlet slots to flow into the installation protective shell, and then the two moving components work synchronously to drive the cleaning. The cleaning component moves, and the cleaning component works while moving to clean the fine dust accumulated on the louver fins in the evaporator body. The cleaned dust falls into two collecting components for collection, which prevents the dust from clogging and corroding the louver fins, and does not affect the working efficiency of the evaporator body. However, the overall use of multiple motors and multiple gears to form a sealing device has a heavy overall weight, which increases the overall weight of the evaporator, and it can only perform two fixed air inlet and outlet strokes of opening and closing during the adjustment of the evaporator intake stroke, and cannot be properly adjusted according to the working power of the evaporator. Therefore, an evaporator for an automobile air conditioner is proposed. Summary of the invention

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] Embodiment 1: Figure 1As shown, the present application discloses an evaporator for automobile air conditioning, comprising a supporting outer frame 100 and an evaporator body 102, the evaporator body 102 is fixedly connected to the inside of the supporting outer frame 100, two diverter boxes 103 are fixedly connected to the inner top wall of the supporting outer frame 100, a plurality of blocking and shrinking airbags 104 are fixedly connected to the outside of the diverter box 103, a micro air pump 101 is fixedly connected to the supporting outer frame 100, an air outlet of the micro air pump 101 is connected to an air delivery hose, an end of the air delivery hose away from the micro air pump 101 passes through the outer wall of the supporting outer frame 100 and is connected to one of the diverter boxes 103, the two diverter boxes 103 are connected to each other through an intermediate pipeline, a plurality of blocking and shrinking airbags 104 connected to the two diverter boxes 103 are respectively located on both sides of the evaporator body 102, the blocking and shrinking airbags 104 are connected to a first electrically controlled valve 105, and an end of the first electrically controlled valve 105 away from the blocking and shrinking airbags 104 is connected to the diverter box 103.

[0029] Specifically, during use, when the evaporator body 102 is in normal operation and the multiple blocking shrinkage airbags 104 are in a normal state, the external airflow can continue to enter the interior of the load-bearing outer frame 100 and come into contact with the evaporator body 102. When the evaporator body 102 is no longer in operation, the staff can start the micro air pump 101 to continuously inject gas into the gas delivery hose. When the gas is continuously injected into the gas delivery hose, the gas will gradually be transported to the inside of the diverter box 103. When the gas is gradually transported to the inside of the diverter box 103, the diverter box 103 will divert the gas to the multiple blocking shrinkage airbags 104 by opening the first electric control valve 105. When the gas is gradually diverted to the interior of multiple blocking and shrinking airbags 104, the multiple blocking and shrinking airbags 104 will gradually expand laterally. When the lateral expansion occurs, the multiple blocking and shrinking airbags 104 will cooperate with the supporting outer frame 100 to form a blockage on the outside of the evaporator body 102. When the blockage is formed, the outside air cannot come into contact with the evaporator body 102, thereby controlling the circulation between the evaporator body 102 and the outside air as a whole. When the evaporator body 102 is no longer working, the multiple blocking and shrinking airbags 104 are used to reduce the flow of air with the outside, thereby reducing the phenomenon of dust in the outside air adhering to the louver fins of the evaporator body 102.

[0030] Furthermore, the blocking and shrinking airbag 104 forms a blockage with a lighter overall weight, and the blocking and shrinking airbag 104 is filled with gas, which will not cause a heavy weight burden during blocking, and during use, the overall blocking will not be affected even if the car experiences a lot of bumps.

[0031] like Figure 4As shown, a plurality of cleaning brush rods 500 are integrally formed on the outside of the shrinkage preventing airbag 104. The initial length of the cleaning brush rods 500 fits the outer wall of the evaporator body 102. During the lateral expansion process of the shrinkage preventing airbag 104, the cleaning brush rods 500 fit the outer wall of the evaporator body 102 to sweep back and forth to reduce dust adhesion.

[0032] Specifically, during use, through the setting of the cleaning brush rod 500, when the shrinking airbag 104 is prevented from expanding lateral direction, the cleaning brush rod 500 can be driven to contact the outside of the evaporator body 102, and by repeatedly urging the shrinking airbag 104 to expand lateral direction, the cleaning brush rod 500 can be driven to repeatedly clean the outside of the evaporator body 102.

[0033] The technical solution in the above-mentioned embodiment of the present application has at least the following technical effects or advantages: relative to the prior art, in the present embodiment, gas is continuously injected into the interior of the diverter box 103 through the micro air pump 101, and in the process of continuously injecting gas into the interior of the diverter box 103, the gas is diverted to the blocking and shrinking airbag 104 through the diverter box 103. When gas continues to enter the blocking and shrinking airbag 104, expansion will occur. When multiple blocking and shrinking airbags 104 continue to expand laterally, the supporting outer frame 100 can be used to seal the evaporator body 102, and the evaporator body 102 is sealed in a separate space, so that the evaporator body 102 is no longer in contact with the outside air when not in use, reducing the phenomenon of dust in the outside air adhering to the louver fins of the evaporator body 102, and the overall weight of the multiple blocking and shrinking airbags 104 filled with gas is lighter, reducing the burden on vehicle operation.

[0034] Embodiment 2: Considering that the automobile evaporator is not always fully loaded during use, when it is running at a lower load, it needs to contact less air. When it needs to contact less air, although the user can adjust the number of expansion of the blocking and shrinking airbags 104 to adjust the overall air intake, the blocking and shrinking airbags 104 expand as a whole during the expansion process. When a few blocking and shrinking airbags 104 expand separately, the air intake duct is vertical, which causes some louver fins of the evaporator body 102 to be unable to contact the air during the air intake stroke, resulting in uneven air intake, which affects the working stroke and heat dissipation stroke of the evaporator body 102. In view of the above technical problems, the present application proposes the following technical solutions to solve the above technical problems, specifically:

[0035] like Figure 4-Figure 5As shown, multiple outward expansion airbags 200 are integrally formed on both sides of the blocking and shrinking airbag 104, and a conveying shunt pipe 201 is fixedly connected to the interior of the blocking and shrinking airbag 104. Multiple outlet positions of the conveying shunt pipe 201 are connected to a second electrically controlled valve 202, and the air inlet of the second electrically controlled valve 202 is connected to the outward expansion airbag 200.

[0036] Specifically, during use, when the evaporator body 102 is not running at full load, the staff can open the inlet and outlet switches connecting the first electrically controlled valve 105 and the blocking and shrinking airbag 104. After opening the inlet and outlet switches connecting the first electrically controlled valve 105 and the blocking and shrinking airbag 104, the gas can be diverted to the interior of the blocking and shrinking airbag 104 through the first electrically controlled valve 105. When the gas continues to enter the interior of the blocking and shrinking airbag 104, the staff can open the second electrically controlled valve 202. When the second electrically controlled valve 202 is opened, the gas inside the delivery shunt pipe 201 will be delivered to the interior of the outward expansion airbag 200. When the gas is continuously delivered to the interior of the outward expansion airbag 200, the outward expansion airbag 200 will expand. When multiple outward expansion airbags 200 continue to expand, an intermittent airflow network can be formed. When the intermittent airbags 200 are formed, After the flow is networked, the expanded outward-expanding airbags 200 can reduce the contact between the air and the evaporator body 102, and the gaps between the multiple outward-expanding airbags 200 can make the air come into contact with the evaporator body 102. During the low-power operation of the evaporator body 102, the air networking formed can effectively reduce the contact amount between the evaporator body 102 and the external air, and block part of the air from coming into contact with the evaporator body 102, thereby meeting the requirements for the evaporator body 102 to come into contact with the air during operation, and further reduce the phenomenon of dust accumulation caused by a large amount of air coming into contact with the evaporator body 102. In addition, the air networking formed can make the air intake of the evaporator body 102 more uniform during the low-efficiency operation, and there will be no phenomenon that only a part of the evaporator body 102 can come into contact with the air, thereby affecting the working stroke and the heat dissipation stroke.

[0037] like Fig. 9 As shown, a placement cavity 600 is provided inside the cleaning brush rod 500 , and a plurality of balls 601 are filled inside the placement cavity 600 .

[0038] Specifically, through the arrangement of multiple balls 601, in the process of preventing the shrinking airbag 104 from expanding laterally and driving the cleaning brush rod 500 to move, the multiple balls 601 will continue to shake inside the inner cavity 600. When the multiple balls 601 are placed inside the inner cavity 600 and continue to shake and contact the evaporator body 102, they can have a knocking effect on the outer surface of the evaporator body 102. The vibration generated by the knocking can shake off the dust attached to the outer surface of the evaporator body 102, further reducing the phenomenon of floating dust adhering to the surface of the evaporator body 102.

[0039] The technical solution in the above-mentioned embodiment of the present application has at least the following technical effects or advantages: relative to embodiment one, in the present embodiment, by continuously filling gas into the interior of multiple outward expansion airbags 200, when gas continues to enter the interior of the multiple outward expansion airbags 200, an air intake barrier net can be formed on the outside of the evaporator body 102. When the air intake barrier net is formed, not only can the evaporator body 102 be evenly in contact with the external air, but also the contact area with the external air can be reduced under low-power operation, thereby reducing the phenomenon of floating dust adhering to the outside of the evaporator body 102.

[0040] Embodiment 3: Considering that although the blocking and shrinking airbag 104 or the outward-expanding airbag 200 can effectively block the evaporator body 102 when it expands, when excessive gas enters the outward-expanding airbag 200 or the blocking and shrinking airbag 104 or the air intake is not the same, it will cause the phenomenon that multiple blocking and shrinking airbags 104 or the outward-expanding airbags 200 cannot be aligned. When multiple blocking and shrinking airbags 104 cannot be aligned, gaps will appear between the multiple blocking and shrinking airbags 104 due to the inability to align. When gaps appear, floating dust in the external air will still adhere to the louver fins of the evaporator body 102. In view of the above technical problems, the present application proposes the following technical solutions to solve the above technical problems:

[0041] like Figure 4-Figure 8 As shown, both sides of the blocking and shrinking airbag 104 and the side of the outward-expanding airbag 200 away from the blocking and shrinking airbag 104 are fixedly connected with electromagnets 300. The electromagnet 300 located on the left side of the blocking and shrinking airbag 104 is a positive magnetic attraction component, and the electromagnet 300 located on the right side of the blocking and shrinking airbag 104 is a negative magnetic attraction component. The electromagnet 300 on the left side and the electromagnet 300 on the right side can be attracted to each other to drive multiple inflated blocking and shrinking airbags 104 to fit closely together, thereby reducing the phenomenon of gaps between adjacent blocking and shrinking airbags 104 after they are inflated.

[0042] Specifically, during use, when multiple blocking and shrinking airbags 104 or outward-expanding airbags 200 are filled with gas and continue to expand, the expansion volume of the blocking and shrinking airbags 104 or outward-expanding airbags 200 increases, and when the multiple blocking and shrinking airbags 104 or outward-expanding airbags 200 are close to each other, the electromagnets 300 located on both sides of the blocking and shrinking airbags 104 and the outward-expanding airbags 200 will produce a mutual adsorption effect. In the case of mutual adsorption, the phenomenon of gaps between the multiple blocking and shrinking airbags 104 and the outward-expanding airbags 200 due to expansion can be avoided, thereby further enhancing the sealing effect of the multiple blocking and shrinking airbags 104 on the evaporator body 102 after expansion.

[0043] like Fig. 9 As shown, a plurality of inclined spray holes 700 are provided on the outside of the cleaning brush rod 500. The inclined spray holes 700 are inclined and are used to transport the gas inside the blocking shrinkage airbag 104 to the placement inner cavity 600. After the gas enters the placement inner cavity 600, it drives the ball 601 to vibrate. When the ball 601 vibrates, it drives the cleaning brush rod 500 to enhance the cleaning performance of the evaporator body 102, and the gas entering the placement inner cavity 600 is sprayed out through the inclined spray holes 700, and the dust attached to the surface of the evaporator body 102 is blown away by the sprayed gas.

[0044] Specifically, through the setting of multiple inclined spray holes 700, during the process of preventing the shrinkage airbag 104 from expanding, the gas inside the shrinkage airbag 104 will enter the interior of the placement cavity 600. When the gas enters the interior of the placement cavity 600, it will blow the ball 601 to further continue to vibrate, thereby strengthening the overall knocking force of the cleaning brush rod 500 on the evaporator body 102, and further enhancing the treatment effect of dust attached to the surface of the evaporator body 102.

[0045] like Figure 1 As shown, a clamping groove is provided at the bottom of the supporting outer frame 100 , and a collection box 800 is clamped inside the clamping groove.

[0046] Specifically, the dust swept by the cleaning brush rod 500 can be collected by the setting of the collection box 800. After the collection is completed, the collection box 800 can be disassembled and the dust inside the collection box 800 can be cleaned centrally.

[0047] The technical solution in the above-mentioned embodiment of the present application has at least the following technical effects or advantages: relative to the second embodiment, in the present embodiment, through the arrangement of multiple electromagnets 300, when the blocking and shrinking airbags 104 or the outward-expanding airbags 200 are blocked and expanded, the electromagnets 300 and the electromagnets 300 between the adjacent blocking and shrinking airbags 104 and the outward-expanding airbags 200 can produce an adsorption effect. When the electromagnets 300 produce an adsorption effect between the multiple blocking and shrinking airbags 104, the blocking effect of the blocking and shrinking airbags 104 on the evaporator body 102 can be further enhanced, and the phenomenon of gaps between the multiple blocking and shrinking airbags 104 can be reduced. In addition, the stability of the network formed by the outward-expanding airbags 200 after lateral expansion is ensured by the arrangement of multiple electromagnets 300.

[0048] Embodiment 4: Considering that although the plurality of blocking and shrinking airbags 104 can be further connected to ensure the tightness of the connection through the adsorption connection between the plurality of electromagnets 300, the plurality of electromagnets 300 are mutually magnetic, and the electromagnets 300 are fixed on the outside of the blocking and shrinking airbags 104 and the outward expansion airbags 200, and the blocking and shrinking airbags 104 and the outward expansion airbags 200 are both made of soft materials and the overall supporting force is insufficient, when the electromagnets 300 move, the electromagnets 300 at adjacent positions may be adsorbed and misaligned, and once one electromagnet 300 is adsorbed and misaligned, more electromagnets 300 will be adsorbed and misaligned, and once the adsorption and misalignment occurs, wrinkles will appear between the blocking and shrinking airbags 104 and the outward expansion airbags 200, and the appearance of wrinkles will still cause gaps between the plurality of blocking and shrinking airbags 104. In view of the above technical problems, the present application proposes the following technical solutions to solve the above technical problems:

[0049] like Figure 6-Figure 7 As shown, the outside of the electromagnet 300 is connected to a plurality of guide plates 400 through a soft film, a first pull rope 401 is integrally formed inside the electromagnet 300 on the left side of the blocking and shrinking airbag 104, and a second pull rope 402 is integrally formed on the outer wall of the plurality of guide plates 400 outside the electromagnet 300 on the right side of the blocking and shrinking airbag 104, the first pull rope 401 and the second pull rope 402 have one end away from the electromagnet 300 that passes through the outer wall of the blocking and shrinking airbag 104 and are fixedly connected to the outer wall of the conveying shunt tube 201.

[0050] Specifically, when multiple blocking and shrinking airbags 104 and outward-expanding airbags 200 are inflated, the first pull rope 401 located at the left position will pull the electromagnet 300 at the middle position. When the electromagnet 300 at the middle position is pulled, and gas continues to enter the inside of the blocking and shrinking airbag 104 or the outward-expanding airbag 200, the blocking and shrinking airbag 104 or the outward-expanding airbag 200 outside the electromagnet 300 will continue to expand outward, and drive the guide plate 400 outside the electromagnet 300 to produce an inclined deformation, so that the left electromagnet 300 and the guide plate 400 form a groove as a whole, and on the right side, as the blocking and shrinking airbag 104 and the outward-expanding airbag 200 continue to expand, the multiple pull ropes connected to the right guide plate 400 will pull The multiple guide plates 400 on the right side stay at the original position, and with the continuous filling of gas, the electromagnet 300 connected by the soft film at the middle position of the multiple guide plates 400 on the right side will protrude outward with the filling of gas to form a plug-in block as a whole. After the groove and the plug-in block are formed, the expansion of the blocking and shrinking airbag 104 will drive the groove and the plug-in block to approach each other. When the groove and the plug-in block are close to each other and come into contact with each other, the groove will guide the plug-in block, so that the plug-in block is accurately inserted into the interior of the groove. When the plug-in block is inserted into the interior of the groove, the adjacent electromagnets 300 will be magnetically attracted again, so as to complete the connection between the multiple blocking and shrinking airbags 104. The guidance of the groove and the plug-in block can reduce the phenomenon of misaligned adsorption of the electromagnets 300 at adjacent positions.

[0051] like Fig. 9 As shown, an electrostatic sticker 900 is integrally formed at one end of the cleaning brush rod 500 away from the blocking and shrinking airbag 104. Through the provision of the electrostatic sticker 900, the electrostatic sticker 900 can be used to adhere to the outer wall of the evaporator body 102 during the process of the cleaning brush rod 500 cleaning the evaporator body 102, so that during the lateral movement of the blocking and shrinking airbag 104, the cleaning brush rod 500 is always in contact with the outer wall of the evaporator body 102, thereby improving the cleaning effect of the cleaning brush rod 500 on the evaporator body 102.

[0052] like Fig. 9 As shown, the cleaning brush rod 500 is integrally formed with an outer rubber magnetic layer 501 on the outside. When the outer rubber magnetic layer 501 is mutually adsorbed, it will drive the inclined spray hole 700 to close. When the outer rubber magnetic layer 501 drives the inclined spray hole 700 to close, it can avoid blocking the gas in the contraction airbag 104 from continuously leaking through the inclined spray hole 700.

[0053] The technical scheme in the above-mentioned embodiment of the present application has at least the following technical effects or advantages: relative to the third embodiment, in the present embodiment, the electromagnet 300 on the left and the guide plate 400 on the right can be pulled respectively by setting the first pull rope 401 on the left and the plurality of second pull ropes 402 on the right, so that the electromagnet 300 and the guide plate 400 on the left are pulled to form a groove shape, and the electromagnet 300 and the guide plate 400 on the right are pulled to form a plug-in block shape. When the groove and the plug-in block are close to each other, the plug-in block can be guided by the groove, and the electromagnets 300 on the adjacent sides are accurately fitted together by the guidance, thereby reducing the phenomenon of misaligned adsorption.

[0054] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
