[0043] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are 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 those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0044] The following combination Figures 1 to 10 , describing the embodiments of the present utility model.

[0045] According to an embodiment of the present invention, an evaporator for construction machinery is provided, comprising an upper housing 1, a lower housing 2, and a filter element 3. The upper housing 1 has a drawer opening 101 at its top, and a slideway 102 is provided within the upper housing 1, communicating with the drawer opening 101. The lower housing 2 is fixedly connected to the upper housing 1. The filter element 3 is disposed in correspondence with the slideway 102 and is removably disposed within the slideway 102 through the drawer opening 101.

[0046] The evaporator using this embodiment is provided with a pull-out opening 101 at the top of the upper shell 1 and a slide 102 is provided inside the upper shell 1. When maintaining the filter element 3 of the evaporator, the filter element 3 is pulled out from the pull-out opening 101 at the top of the upper shell 1, and then the filter element 3 is maintained. After the filter element 3 is maintained, the filter element 3 is pushed from the pull-out opening 101 into the slide 102, thereby completing the maintenance of the filter element 3. The filter element 3 is pushed in or out by pushing and pulling the filter element 3, and there is no need to disassemble the upper shell 1 and other components, which improves the convenience of maintaining the evaporator filter element 3, saves manpower and working hours, and reduces the risk of wear and failure of parts caused by repeated disassembly.

[0047] In one embodiment, Figures 1 to 4 As shown, the upper housing 1 includes a housing body 103 and a slide 104. The housing body 103 has a mounting cavity for mounting the filter element 3. The slide 104 is disposed within the mounting cavity. The mounting cavity has two opposing side walls, and a slideway 102 is formed between the side walls and the slide 104. The slide 104 is disposed within the housing body 103, and the slideway 102 is formed between the side walls of the housing body 103 and the slide 104. The provision of the slide 104 not only facilitates the formation of the slideway 102, but also supports the housing body 103 through the slide 104, thereby ensuring the structural strength of the upper housing 1.

[0048] Furthermore, when there is one slide 104, two slideways 102 are formed between one slide 104 and the two side walls, and in this case, there are two filter elements 3. Of course, when there are multiple slides 104, multiple slides 104 are spaced apart between the two side walls, and slideways 102 are also formed between two adjacent slides 104.

[0049] It should be noted that the number of pull-out openings 101 can be one, two or more than three, and the corresponding filter elements 3 can be one, two or more than three. The number of slides 104 used to separate the slides 102 is also different, and the pull-out maintenance of the filter element 3 of the evaporator can be achieved.

[0050] It is understandable that, in another embodiment, the slide 104 may not be provided, and the slideway 102 may be formed between the two side walls. In this case, the number of the filter element 3 is only one.

[0051] In one embodiment, Figure 1 and Figure 4As shown, the slide 104 includes a first slide 1041, a second slide 1042, and a connecting plate 1043. The first slide 1041 and the second slide 1042 are arranged opposite each other, and the connecting plate 1043 is connected between the first slide 1041 and the second slide 1042. Each side of the connecting plate 1043, the first slide 1041 and the second slide 1042 form a first slide groove 1044. The side wall has a second slide groove. The second slide groove, the first slide groove 1044 adjacent to the second slide groove, and the space between them form the slideway 102. Forming the slide 104 from plate materials has a simple structure and is easy to implement. The cross-section of the first slide 1041, the second slide 1042, and the connecting plate 1043 is similar to an I-beam or H-shape.

[0052] In one embodiment, the slideway 102 extends in an angled direction relative to the height of the evaporator. To push the filter element 3 inward, align the lower end of the filter element 3 with the drawer opening 101 and then push the filter element 3 directly into the slideway 102 at an angle. To pull the filter element 3 outward, simply pull it out at an angle. This angled push and pull of the filter element 3 saves effort, reducing the workload for maintenance personnel.

[0053] It is understandable that in another embodiment, the extension direction of the slide 102 is along the height direction of the evaporator. In this case, the filter element 3 can also be maintained by pushing and pulling the filter element 3 in the vertical direction.

[0054] In one embodiment, Figure 1 and Figure 4 As shown, the slide 104 further includes a limit plate 1045, which is disposed at the lower end of the first slide 1041 and the lower end of the second slide 1042. The limit plate 1045 is used to limit the lower end of the filter element 3. The limit plate 1045 limits the position of the filter element 3 to prevent the filter element 3 from being inserted too deep and making it difficult to remove the filter element 3.

[0055] In one embodiment, the slide 104 further includes a first fixing member 1046 and a second fixing member 1047. The first fixing member 1046 is disposed at the upper end of the first slide 1041, and the second fixing member 1047 is disposed at the lower end of the second slide 1042. The first fixing member 1046 and the second fixing member 1047 can be used to fix the slide 104 to the housing body 103, and the fixing method is simple.

[0056] Furthermore, the first fixing member 1046 and the second fixing member 1047 are both fixed to the shell body 103 by fasteners, which are bolts or screws, etc. The slide 104 is assembled into one with the shell body 103 by bolts or screws. The slide 104 strengthens the structural strength of the shell body 103 and reduces the risk of pressure damage to the evaporator.

[0057] Specifically, a first fixing hole is provided on the first fixing member 1046 , a second fixing hole is provided on the second fixing member 1047 , the fastener passes through the first fixing hole to be connected to the shell body 103 , and the fastener passes through the second fixing hole to be screwed to the shell body 103 .

[0058] It is understandable that, in another embodiment, the slide 104 and the shell body 103 are integrally formed, that is, the slide 104 and the shell body 103 are made into a whole.

[0059] In one embodiment, Figure 1 and Figure 4 As shown, the carriage 104 further includes a reinforcing plate 1048, which is disposed on a side of the second slide 1042 facing away from the first slide 1041. One end of the reinforcing plate 1048 extends toward the connecting plate 1043 and extends to the top side of the connecting plate 1043. Reinforcing ribs 1049 are provided between the first slide 1041 and the connecting plate 1043, between the second slide 1042 and the connecting plate 1043, and between the reinforcing plate 1048 and the second slide 1042 and the connecting plate 1043. The reinforcing plate 1048 and the reinforcing ribs 1049 can enhance the structural strength of the carriage 104 and prevent the carriage 104 from deforming under external forces.

[0060] In one embodiment, Figure 5 As shown, the filter element 3 comprises a core 301, a sealing member 302, and a pull-out operating member 303. The four sides of the core 301 form a pull-out surface and three sealing surfaces, each of which is provided with a sealing member 302 and a pull-out operating member 303. Except for the pull-out surface, the remaining three sides of the filter element 3 are covered with sealing members 302, eliminating any gaps between the filter element 3 and the housing 103 and ensuring a tight seal. When maintaining the filter element 3, maintenance personnel use the pull-out operating member 303 to push and pull the filter element 3, facilitating operation.

[0061] Furthermore, the pulling operating member 303 is a pulling rope, which has a simple structure and low cost.

[0062] It is understandable that, in another embodiment, the pulling operating member 303 is a handle or the like.

[0063] According to an embodiment of the present invention, on the other hand, a construction machine is provided, such as Figure 8 As shown, the vehicle comprises a cab, which comprises a cab body 7, a seat 6 and the above-mentioned evaporator. The seat 6 is arranged in the cab body 7; the evaporator is arranged in the cab body 7 and at the rear side of the seat 6.

[0064] A hole is opened at the top of the upper shell 1 and several slideways 102 are provided inside to ensure that the filter element 3 can be pushed in or out of the evaporator. When maintaining the filter element 3, it is only necessary to pull out the filter element 3 from the top of the evaporator, replace the new filter element 3 and push it into the upper shell 1 to complete the maintenance, thereby realizing the pull-out maintenance of the filter element 3, solving the problem of poor convenience when maintaining the evaporator filter element, saving manpower and working hours when maintaining the filter element 3, and reducing the risk of parts wear and failure caused by repeated disassembly.

[0065] In order to make the cab clean and arrange other functional components, the evaporator will be covered by other parts. In one embodiment, Figure 8 As shown, the cab further includes a protective cover 4, which is provided on the outside of the evaporator and has a pull-out opening 401 for the filter element 3 to pass through. When the protective cover 4 is provided on the outside of the evaporator, the filter element 3 can be quickly maintained by simply leaving the pull-out opening 401 on the protective cover 4 for withdrawing or inserting the filter element 3.

[0066] In one embodiment, Figure 8 As shown, the cab further includes a storage box 5, which is located above the evaporator and has a pull-out channel 501 for the filter element 3 to pass through. When the storage box 5 is located above the evaporator, the filter element 3 can be quickly maintained by simply leaving the pull-out channel 501 in the storage box 5 for pulling out or pushing in the filter element 3.

[0067] Furthermore, a protective cover 4 is provided on the outside of the evaporator, and a storage box 5 is provided above the protective cover 4. By simply leaving a pull-out opening 401 on the protective cover 4 for pulling out or pushing in the filter element 3 and leaving a pull-out channel 501 on the storage box 5 for pulling out or pushing in the filter element 3, the filter element 3 can be quickly maintained.

[0068] Specifically, if Figure 6 、 Figure 9 As shown in Figure 10 , the evaporator has an air inlet 105. The air inlet 105 can be arranged at an angle to the filter element 3, or it can be arranged parallel to the filter element 3. Specifically, when the filter element 3 is tilted, the air inlet 105 can be arranged in a vertical direction, or it can be tilted relative to the vertical direction. When the filter element 3 is vertically arranged, the air inlet is in a vertical direction. The relative position of the air inlet 105 and the filter element 3 can be positioned according to actual needs, while allowing the filter element 3 to be pulled in different directions, facilitating the placement of the evaporator in different positions on the actual vehicle, thereby achieving the need for convenient maintenance of the evaporator filter element 3.

[0069] Furthermore, the housing 103, filter element 3, and carriage 104 can be designed in various configurations based on the direction of wind flow, allowing air to pass through the filter element 3 vertically or at varying angles. This facilitates the placement of the evaporator on construction machinery and facilitates maintenance of the filter element 3. When servicing the filter element 3, there is no need to remove the upper housing 1 or other covering components, improving the convenience of filter element 3 maintenance, saving manpower and time, and reducing the risk of wear and failure due to repeated disassembly.

[0070] Specifically, the cab further includes an air conditioner, which includes an evaporator, etc. The air conditioner also has two air outlets 106, one air outlet 106 is located at the rear side of the evaporator, and the other is located at the front side of the lower part of the air conditioner.

[0071] In one embodiment, the engineering machinery includes but is not limited to an excavator, a crane, a pile driver, a mixer, and the like.

[0072] Although the embodiments of the present invention have been described with reference to the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations shall fall within the scope defined by the appended claims.
