For those skilled in the art, the specific meaning of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0035] As Figures 1 to 4As shown, a kitchen air conditioner 10 comprises a cabinet 100, a fan 200 and a plurality of heat exchange elements 300. The cabinet 100 is provided with an inner cavity, and the inner cavity is provided with an evaporative box 400. The evaporative box 400 divides the inner cavity into a blowing area and a heat exchange area. An air inlet 120 is formed on the outer side wall of the cabinet 100 and communicates with the blowing area. The air inlet 120 is used to communicate with the outdoor. An air outlet 130 is also formed on the outer side wall of the cabinet 100 and communicates with the heat exchange area. The air outlet 130 is used to communicate with the indoor. The fan 200 is arranged in the blowing area and communicates with one end of the evaporative box 400 close to the blowing area. Each heat exchange element 300 is arranged in the evaporative box 400 and is spaced apart in the cross section perpendicular to the air direction. One end of each heat exchange element 300 close to the blowing area communicates with each other. One end of each heat exchange element 300 close to the heat exchange area communicates with each other.

[0036] It should be noted that the air inlet 120 is directly communicated with the outdoor, and the outdoor air is sucked into the air blowing area when the fan 200 is running, forming an external circulation path independent of the indoor air. By physically isolating the high-oil smoke air in the kitchen, the direct entry of heavy oil smoke air in the kitchen into the evaporative box 400 and the air duct system is avoided. The outdoor fresh air enters the evaporative box 400 through the air blowing area and exchanges heat with the refrigerant, and the cold air finally flows into the indoor from the air outlet 130. In this way, the oil pollution invasion channel is cut off from the source. Among them, each heat exchange element 300 is spaced apart in the evaporative box 400 along a direction perpendicular to the wind direction (i.e. the direction from the fan 200 to the air outlet 130), forming a parallel heat exchange structure. The refrigerant flows into the inlet end of each heat exchange element 300 close to the air blowing area in parallel, exchanges heat with the air when flowing through each heat exchange element 300, and finally flows out at the outlet end of each heat exchange element 300 close to the air outlet 130. The introduction of outdoor fresh air into the refrigeration makes the air conditioner internal (especially the evaporative box 400) completely isolated from the kitchen oil smoke, compared with the traditional air conditioner, avoiding the deposition of oil pollution in the air conditioner internal, thereby avoiding the oil pollution to block the air passage in the air conditioner internal. The air inlet 120 does not need to be equipped with a high-density oil pollution filter screen, and only needs to be equipped with a basic dust screen, which greatly reduces the maintenance cost. It should be noted that the kitchen is a relatively closed space, and the temperature is usually 3°-8° higher than the outdoor temperature at the same period without starting the air extraction equipment. Therefore, compared with sucking the air in the kitchen for refrigeration, sucking the outdoor fresh air can effectively reduce the refrigeration load of the air conditioner. In addition, the closed space in the cabinet 100 is divided into two relatively independent areas by the evaporative box 400, the fan 200 is installed in the air blowing area, and each heat exchange element 300 is installed in the evaporative box 400, which is simple in structure. Further, each heat exchange element 300 and the evaporative box 400 can be designed as an integrated structure, so that the fan 200, the evaporator (composed of the evaporative box 400 and each heat exchange element 300), and the cabinet 100 can be modularly installed, which can effectively improve the production efficiency compared with the traditional split-type air conditioner, and is convenient for subsequent maintenance and replacement. In this way, by introducing outdoor fresh air for refrigeration, the heavy oil smoke air in the kitchen is avoided to enter the air conditioner internal, so that the air conditioner internal can realize long-term cleaning; at the same time, by setting each heat exchange element 300 as a parallel heat exchange structure perpendicular to the wind direction, the air can be quickly refrigerated to realize high-efficiency heat exchange.

[0037] As shown in Figure 1 In an embodiment, the bottom of the cabinet 100 is provided with two horizontal rods 510, and the two horizontal rods 510 are located on the two ends of the bottom side of the cabinet 100.

[0038] It should be noted that a bolt hole is formed on each end of the horizontal rod 510, and the cabinet 100 can be fixed to the wall / ceiling by fixing the horizontal rod 510 through bolts or hanging supports, so as to be conveniently installed in the kitchen ceiling.

[0039] As shown in Figure 4 In an embodiment, the inner bottom wall of the cabinet 100 is further provided with a water pan 610, which is located below the fan 200 and the evaporative cabinet 400.

[0040] It should be noted that the water pan 610 is installed directly below the fan 200 and the evaporative cabinet 400, and the condensed water on the surface of the evaporative cabinet 400 naturally drips down, realizing self-collection of condensed water without pump. In an embodiment, a flow guide hole is formed on one end of the water pan 610, so that the accumulated water in the water pan 610 can flow out along the flow guide hole, avoiding stagnation of accumulated water. Further, in an embodiment, the edge of the water pan 610 has a turned-up baffle, which can accommodate sudden large flow of condensed water in extreme working conditions such as high temperature and high humidity, and prevent water vapor from penetrating out of the gap of the cabinet 100.

[0041] As shown in Figure 1 In an embodiment, a handle 710 is arranged on the outer side wall of the cabinet 100. In this way, the side plate of the cabinet 100 can be easily disassembled through the handle 710, so as to facilitate replacement and maintenance of the fan 200 or the evaporative cabinet 400 and the heat exchange element 300 in the cabinet 100.

[0042] As shown in Figure 5 and Figure 6 In an embodiment, the heat exchange element 300 includes at least two heat exchange pipe networks 310 which are sequentially connected, each heat exchange pipe network 310 is arranged in the evaporative cabinet 400, and each heat exchange pipe network 310 is distributed along the air direction in the evaporative cabinet 400 and is distributed in a staggered manner between any two adjacent heat exchange pipe networks 310.

[0043] It should be noted that each heat exchange pipe network 310 forms a multi-stage heat exchange unit in a series connection manner, and the refrigerant flows through each heat exchange pipe network 310 in sequence to realize temperature gradient type step-by-step cooling. Each heat exchange pipe network 310 adopts an S-shaped coil layout, and the refrigerant completes at least one flow direction reversal in a single heat exchange pipe network 310, prolongs the residence time, and ensures that the phase change process of the refrigerant is fully completed. The adjacent two heat exchange pipe networks 310 are installed in a staggered manner, so that the air flow effect when the air flows through the evaporative cabinet 400 can be increased, so that the air can be fully contacted and heat exchanged with each heat exchange pipe network 310. It should be noted that the number of heat exchange pipe networks 310 can be two, or three, or four, or five, or six, and each heat exchange pipe network 310 is connected in sequence.

[0044] As shown in Figure 5 and Figure 6 In an embodiment, the heat exchange pipe network 310 includes at least two through pipes 311, each through pipe 311 is arranged in the evaporative cabinet 400, and each through pipe 311 is distributed in the evaporative cabinet 400 in a cross section perpendicular to the air direction, and each through pipe 311 is sequentially and staggeredly connected in sequence.

[0045] It should be noted that each pipe 311 is sequentially connected end to end, so that the formed heat exchange pipe network 310 is in an S-shaped structure, so that the heat exchange efficiency of air and the heat exchange pipe network 310 is improved.

[0046] As shown in Figure 5 and Figure 6 , in an embodiment, each heat exchange element 300 is connected in pairs to form several heat exchange groups A, each heat exchange group A is spaced apart in the cross section perpendicular to the air direction in the evaporation box 400, and the leading ends of each heat exchange element 300 close to the air blowing area in each heat exchange group A are connected to each other, and the trailing ends of each heat exchange element 300 close to the air outlet 130 in each heat exchange group A are connected to each other.

[0047] It should be noted that in this embodiment, every two heat exchange elements 300 are connected to each other to form a single heat exchange group A. That is, the two heat exchange elements 300 in a single heat exchange group A form a two-section heat exchange structure.

[0048] In an embodiment, the heat exchange element 300 is provided as eight, and therefore four heat exchange groups A are provided. The structure of the two heat exchange elements 300 in each heat exchange group A is identical, that is, the number of heat exchange pipe networks 310 of the two heat exchange elements 300 in each heat exchange group A is consistent. In this way, the two-section heat exchange structure is spaced apart in the cross section perpendicular to the air direction in the evaporation box 400, so that the air flowing through the evaporation box 400 can be fully contacted with the heat exchange element 300.

[0049] Further, in an embodiment, the heat exchange element 300 is provided as sixteen, and therefore eight heat exchange groups A are provided. In this embodiment, the structure of the two heat exchange elements 300 in each heat exchange group A is different, that is, the number of heat exchange pipe networks 310 of the two heat exchange elements 300 in each heat exchange group A is inconsistent. Therefore, through the above two embodiments, it is shown that the number of heat exchange pipe networks 310 of the two heat exchange elements 300 connected in front and back in the two-section heat exchange structure formed in the heat exchange group A in the present application can be set to any number according to actual needs.

[0050] As shown in Figure 7 , in an embodiment, a through hole 410 is formed on an outer side wall of the evaporation box 400, and the through hole 410 is located between the two heat exchange elements 300 of the heat exchange group A.

[0051] It should be noted that in the present application, a plurality of heat exchange elements 300 are installed in the evaporation box 400, in order to facilitate subsequent cleaning of each heat exchange element 300 in the evaporation box 400, and therefore a through hole 410 is formed on the outer side wall of the evaporation box 400, and the heat exchange element 300 and the inner side wall of the evaporation box 400 can be cleaned through the through hole 410.

[0052] As shown in Figure 7As shown, in an embodiment, the evaporation box 400 is detachably provided with a cover plate 810, and the cover plate 810 is used to shield the through hole 410. In this way, the through hole 410 is shielded by the cover plate 810, so as to avoid the air flowing in the evaporation box 400 from flowing out of the through hole 410.

[0053] As shown, in an embodiment, the inner side wall of the air inlet 120 is provided with a dust screen 910. In this way, the dust screen 910 is used to filter the dust and other sundries in the outdoor air, so as to avoid the sundries flowing into the cabinet 100. Figure 1

[0054] Further, it needs to be explained that when the kitchen air conditioner 10 is used in cooperation with the air exhaust equipment, the effect is as follows. Specifically, the traditional air conditioner is used to cool the indoor air. When the air exhaust equipment is started, the air in the kitchen will be exhausted to the outdoor to form a low pressure, so that the air in the living room will enter the kitchen through the door and window gaps, thereby causing the air pressure in the kitchen to be unbalanced (and the air conditioner cold air in the living room will be sucked into the kitchen, increasing the energy consumption of the air conditioner in the living room). The kitchen air conditioner 10 of the present application cools by sucking outdoor fresh air, and works in cooperation with the air exhaust equipment, so that the amount of air entering and leaving the kitchen remains the same, thereby keeping the air pressure in the kitchen balanced, and the air conditioner cold air in the living room will not be sucked into the kitchen.

[0055] The above-described embodiments only express several embodiments of the present application, and the description is more specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. In the present application, the installation / fixed / setting is understood to include but not limited to locking and fixing by using screws / bolts, welding, unless otherwise defined. It should be noted that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are within the scope of the present application. Therefore, the protection scope of the present application patent should be subject to the appended claims.​
