[0051] The following describes in detail embodiments of the present application. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application.

[0052] The present application discloses an air conditioner outdoor unit.

[0053] Reference below Figure 1-Figure 4 An air conditioner outdoor unit according to an embodiment of the present application is described.

[0054] In some embodiments, as Figure 1-Figure 3 As shown (the complete casing is not shown in any of the figures), the air-conditioning outdoor unit includes: a casing, a compressor 300 and a heat exchanger 200.

[0055] The casing defines a first accommodating cavity; the compressor 300 is installed in the first accommodating cavity; the heat exchanger 200 is installed in the first accommodating cavity, and the heat exchanger 200 is arranged around the outside of the compressor 300, and the heat exchanger 200 includes a first tube and a second tube, one of the first tube and the second tube is arranged outside the other, the refrigerant inlet 210 of the first tube is connected to the outlet of the compressor 300, and the second tube has a first port 230 for connecting to a water source and a second port 240 for drainage.

[0056] In this embodiment, if Figure 1-Figure 3 As shown, the first tube can be sleeved outside the second tube, the cross-sectional shape of the first tube can be annular, and the cross-sectional shape of the second tube can be circular.

[0057] In other embodiments, the second tube may be sleeved outside the first tube, the cross-sectional shape of the second tube may be annular, and the cross-sectional shape of the first tube may be circular.

[0058] The heat exchanger 200 is the condenser of the entire kitchen air-conditioning system. The refrigerant inlet 210 of the first pipe is connected to the outlet of the compressor 300, the refrigerant outlet 220 of the first pipe is connected to the air-conditioning indoor unit, the first port 230 of the second pipe is connected to the water source, and the second port 240 of the second pipe is connected to the sewer and / or water tank and / or hot water faucet.

[0059] In actual implementation, Figure 2-Figure 3As shown, the heat exchanger 200 can be wrapped around the outside of the compressor 300 in a curled shape. Specifically, the heat exchanger 200 can be wrapped around the outside of the compressor 300 one or more times, where multiple times means two or more times. It can be understood that in order to ensure sufficient heat exchange between the refrigerant and the coolant, the first tube and the second tube need to have sufficient heat exchange contact area, so the length of the heat exchanger 200 is usually set to be larger. If the heat exchanger 200 is only wrapped around a single circle, the outer diameter of the heat exchanger 200 is too large, resulting in the single-circle heat exchanger 200 being able to be stuffed into the accommodating cavity in a disordered, folded and twisted posture. If the heat exchanger 200 is wrapped around multiple times, the outer diameter of each circle can be limited. The heat exchanger 200 is only stacked in height for each additional circle, which directly reduces the floor space occupied by the entire casing in the spatial layout.

[0060] For example, in some embodiments, Figure 2-Figure 3 As shown, the heat exchanger 200 surrounds the outside of the compressor 300 four times.

[0061] Preferably, the heat exchanger 200 may be arranged in a coiled form. In other words, the outer diameter of each coil may be substantially the same.

[0062] The air-conditioning outdoor unit provided in the embodiment of the present application has a structural design in which the above-mentioned heat exchanger 200 surrounds the outside of the compressor 300. This can reserve sufficient space for the arrangement of other components without affecting the cooling capacity of the kitchen air-conditioning system, thereby greatly reducing the size of the air-conditioning outdoor unit and solving the problem of the kitchen air-conditioning system having no outdoor unit installation position, thereby meeting the needs of installing the air-conditioning outdoor unit in multiple locations such as the kitchen, living balcony or shared outdoor unit position.

[0063] In some embodiments, as Figure 4 As shown, the first tube can be sleeved outside the second tube, the refrigerant inlet 210 and the refrigerant outlet 220 of the first tube can be located on the side of the heat exchanger 200, and the first port 230 and the second port 240 of the second tube can be located at the end of the heat exchanger 200.

[0064] In this embodiment, if Figure 4As shown, the entire heat exchanger 200 can be arranged in a square coiled shape, with refrigerant medium flowing in the first tube and cooling water flowing in the second tube. The refrigerant inlet 210 and the refrigerant outlet 220 can be set on the same side or diagonally, and the refrigerant inlet 210 and the refrigerant outlet 220 can be respectively located on the sides of the entire heat exchanger 200 at both ends. The first port 230 and the second port 240 can be set on the same side or diagonally, and the first port 230 and the second port 240 can be respectively located at the ends of the entire heat exchanger 200 at both ends. The refrigerant can enter the first tube located in the outer circle from the refrigerant inlet 210 located on the side of the heat exchanger 200, and the refrigerant can leave the first tube located in the outer circle from the refrigerant outlet 220 located on the side of the heat exchanger 200. The cooling water can enter the second tube located in the inner circle from the first port 230 located at the end of the heat exchanger 200, and the cooling water can leave the second tube located in the inner circle from the second port 240 located at the end of the heat exchanger 200. The inner wall of the first tube can contact the outer wall of the second tube and exchange heat.

[0065] In other embodiments, the second tube can be sleeved outside the first tube, the refrigerant inlet 210 and the refrigerant outlet 220 can be located at the end of the heat exchanger 200, and the first port 230 and the second port 240 can be located on the side of the heat exchanger 200.

[0066] The air-conditioning outdoor unit provided in the embodiment of the present application, through the structural design of the second tube being arranged outside the first tube, combined with the position design of the refrigerant inlet 210, the refrigerant outlet 220, the first port 230 and the second port 240, separates the refrigerant side and the inlet and outlet as well as the inlet and outlet of the water side as much as possible, reduces the probability of interference between the refrigerant side and the water side, and thus optimizes the performance of the entire kitchen air-conditioning system.

[0067] In some embodiments, as Figure 4 As shown, the refrigerant inlet 210 may be disposed close to the second port 240 , and the refrigerant outlet 220 may be disposed close to the first port 230 .

[0068] In this embodiment, if Figure 4 As shown, the entire heat exchanger 200 can be arranged in a square coiled shape, and the inlet and outlet of the first tube and the inlet and outlet of the second tube can be arranged in opposite directions. Specifically, the heat exchanger 200 can have a first end and a second end, the refrigerant inlet 210 can be arranged on the side of the first end, the second port 240 can be arranged at the end of the first end, the refrigerant outlet 220 can be arranged on the side of the second end, and the first port 230 can be arranged at the end of the second end. During the heat exchange process, the flow direction of the refrigerant in the first tube is opposite to the flow direction of the cooling water in the second tube.

[0069] The first end and the second end may be arranged on the same side or diagonally, which is not limited here.

[0070] The air-conditioning outdoor unit provided in the embodiment of the present application realizes the reverse flow of the refrigerant and the cooling water in the heat exchanger 200 through the position design of the above-mentioned refrigerant inlet 210, refrigerant outlet 220, first port 230 and second port 240. Compared with the scheme of unidirectional flow, the heat exchange amount between the refrigerant and the cooling water per unit volume per unit time is increased, thereby significantly improving the heat exchange efficiency.

[0071] In some embodiments, as Figure 2-Figure 4 As shown, the heat exchanger 200 may further include a first bracket 250 .

[0072] The first bracket 250 may be connected between the outermost one of the first tube and the second tube and the housing.

[0073] The first bracket 250 can be made of metal material or plastic material, wherein the metal material may include but is not limited to stainless steel, aluminum alloy or titanium alloy, etc., and the plastic material may include but is not limited to PS (Polystyrene), PP (polypropylene) or PC (Polycarbonate), etc., which are not limited here.

[0074] For example, in some embodiments, the first bracket 250 is made of stainless steel.

[0075] like Figure 2-Figure 4 As shown, the first bracket 250 can be in the shape of a bent plate, and the first bracket 250 can be provided with one or more connecting structures for connecting to the casing, and the multiple connecting structures can be connected to the bottom wall and / or side wall of the accommodating cavity, wherein the connection method between the first bracket 250 and the casing can include but is not limited to bolt connection, riveting or snap connection, etc., which is not limited here.

[0076] like Figure 4 As shown, when the first tube is sleeved outside the second tube, the first bracket 250 is connected to the first tube, wherein the connection method between the first bracket 250 and the first tube may include but is not limited to welding, bonding or snap connection, etc., which is not limited here.

[0077] When the second tube is sleeved outside the first tube, the first bracket 250 is connected to the second tube, wherein the connection method between the first bracket 250 and the second tube may include but is not limited to welding, bonding or snap connection, etc., which is not limited here.

[0078] The air-conditioning outdoor unit provided in the embodiment of the present application realizes the assembly between the heat exchanger 200 and the casing through the provision of the above-mentioned first bracket 250. Compared with the solution in which the sleeve-shaped heat exchanger 200 is directly fixed to the casing, the reliability of the connection between the heat exchanger 200 and the casing is enhanced, and the heat exchanger 200 is prevented from shaking freely in the casing due to the unsecured installation of the heat exchanger 200, thereby improving the stability of the heat exchanger 200.

[0079] In some embodiments, as Figure 1-Figure 3 As shown (the box cover is not shown in any of the figures), the casing may include: a box body and a box cover.

[0080] The box body may include a base 110 and a side panel 120 , and the heat exchanger 200 and the compressor 300 may be installed on the base 110 ; the box cover and the base 110 may be arranged opposite to each other, and the box cover may be connected to the side panel 120 .

[0081] The box body and the box cover can jointly define a first accommodating cavity, the base 110 can be provided with multiple flanges extending upward, the side panel 120 can include multiple side panels connected end to end, the multiple side panels can have multiple faces, and the multiple flanges can correspond one-to-one to the multiple side panels.

[0082] For example, in some embodiments, Figure 1-Figure 3 As shown, the side panel 120 includes four side panels connected end to end, the four side panels have four faces, and the four flanges correspond to the four side panels one by one.

[0083] The connection method between the base 110 and the side panel 120 may include, but is not limited to, bolt connection, riveting or snap connection, etc., which is not limited here.

[0084] For example, in some embodiments, the base 110 and the side panel 120 are connected by bolts.

[0085] The connection method between the box cover and the side panel 120 may include, but is not limited to, bolt connection, riveting or snap connection, etc., which is not limited here.

[0086] For example, in some embodiments, the connection between the box cover and the side panel 120 is bolted.

[0087] The air-conditioning outdoor unit provided in the embodiment of the present application realizes the installation of the heat exchanger 200 and the compressor 300 on the base 110 of the box body through the arrangement of the above-mentioned box body and the box cover, thereby improving the reliability of the assembly of the heat exchanger 200 and the compressor 300. At the same time, during the coiled arrangement of the heat exchanger 200, the side panel 120 can be used to enclose the heat exchanger 200, thereby facilitating the molding of the spiral structure and accelerating the production rate.

[0088] In some embodiments, as Figure 1As shown, the air conditioner outdoor unit may further include: a wiring structure 400 .

[0089] At least a portion of the wiring structure 400 may be installed in the first accommodation cavity, the wiring structure 400 may be connected to the first surface 121 of the side panel 120 , and the wiring structure 400 may be located on a side of the heat exchanger 200 close to the box cover.

[0090] In this embodiment, if Figure 1 As shown, the wiring structure 400 may include a wiring board and multiple cables. The wiring board may be connected to the inner side of the first surface 121. At least part of the multiple cables may pass through the first surface 121. The wiring structure 400 may be vertically arranged above the heat exchanger 200, and the wiring structure 400 may be located between the compressor 300 and the first surface 121 of the side panel 120.

[0091] The connection method between the wiring structure 400 and the first surface 121 of the side panel 120 may include, but is not limited to, bolt connection, riveting, or snap connection, etc., which is not limited here.

[0092] For example, in some embodiments, the connection between the wiring structure 400 and the first surface 121 of the side panel 120 is a bolt connection.

[0093] The air-conditioning outdoor unit provided in the embodiment of the present application realizes the separate arrangement of the wiring structure 400, the compressor 300 and the heat exchanger 200 through the setting of the above-mentioned wiring structure 400, reduces the mutual interference between the wiring structure 400, the compressor 300 and the heat exchanger 200, and simplifies the installation and disassembly operations of the wiring structure 400.

[0094] In some embodiments, as Figure 1-Figure 3 As shown, the box body may further include: a first buckle portion 1211 and a second buckle portion 1221.

[0095] The first buckle portion 1211 can be a part of the first surface 121 of the side panel 120, and the first buckle portion 1211 can be arranged to protrude inwardly. The second buckle portion 1221 can be a part of the second surface 122 of the side panel 120, and the second buckle portion 1221 can be arranged to protrude inwardly. The first surface 121 and the second surface 122 can be arranged opposite to each other. The wiring structure 400 can be installed on the inner wall surface of the first buckle portion 1211. The first buckle portion 1211 can be provided with a wiring hole, and the cable of the wiring structure 400 can be suitable for passing through the wiring hole.

[0096] like Figure 1-Figure 3As shown, the first buckle portion 1211 and the second buckle portion 1221 can form a concave shape toward the first accommodating cavity. When the relevant operator is carrying the air-conditioning outdoor unit, he can respectively buckle the first buckle portion 1211 and the second buckle portion 1221 with both hands. The first buckle portion 1211 and the second buckle portion 1221 can be used as a relatively labor-saving gripping point to facilitate the relevant operators to carry out assembly and disassembly work.

[0097] At least a portion of the wiring structure 400 can fit and be connected to the inner wall surface of the first buckle portion 1211. Based on the concave design of the first buckle portion 1211, the cables of the wiring structure 400 can be accommodated in the recessed space of the first buckle portion 1211, thereby protecting the cables of the wiring structure 400 and facilitating subsequent cable maintenance work.

[0098] In some embodiments, as Figure 1 As shown, the box body may further include a handle 130 .

[0099] The handle 130 and the first handle portion 1211 can be detachably connected, and the handle 130 and the first handle portion 1211 can form a wiring cavity, and the cables of the wiring structure 400 can be suitable for installation in the wiring cavity.

[0100] The connection method between the handle 130 and the first handle portion 1211 may include but is not limited to bolt connection, snap connection or pin connection, etc., which is not limited here.

[0101] For example, in some embodiments, the connection between the handle 130 and the first handle portion 1211 is a bolt connection.

[0102] The handle 130 can be configured as a square cover, and the handle 130 can be provided with a gripping groove. The specific shape of the gripping groove can be designed according to the characteristics of the human hand to optimize the hand feel of the relevant operator when gripping the handle 130.

[0103] After the wiring structure 400 and the first buckle portion 1211 are assembled, the handle 130 can be covered and connected to the first buckle portion 1211 to hide the cables of the wiring structure 400 in the second accommodating cavity, thereby preventing the cables of the wiring structure 400 from being exposed for a long time and causing accelerated aging, thereby improving the safety of the air-conditioning outdoor unit, and during maintenance, only the handle 130 needs to be removed to diagnose the cables of the wiring structure 400, thereby improving the maintainability of the wiring structure 400.

[0104] In some embodiments, as Figure 1-Figure 2 As shown, the air-conditioning outdoor unit may further include: an electric control component 500 and a second bracket 600 .

[0105] The electronic control component 500 can be installed in the first accommodating cavity near the third surface 123 of the side panel 120, and the electronic control component 500 can be located on the side of the heat exchanger 200 near the box cover; the electronic control component 500 can be connected to the base 110 through the second bracket 600.

[0106] In this embodiment, if Figure 1-Figure 2 As shown, the electronic control component 500 can be in the shape of a square box, and the side of the electronic control component 500 close to the compressor 300 can be connected to the second bracket 600, and the side of the electronic control component 500 away from the compressor 300 can be close to the third surface 123 of the side panel 120, or only leave a narrow gap. The electronic control component 500 can be vertically arranged above the heat exchanger 200, and the electronic control component 500 can be located between the compressor 300 and the third surface 123 of the side panel 120.

[0107] Among them, the second bracket 600 can be made of metal material or plastic material, among which the metal material can include but is not limited to stainless steel, aluminum alloy or titanium alloy, and the plastic material can include but is not limited to PS (Polystyrene), PP (polypropylene) or PC (Polycarbonate), etc., and there is no restriction here.

[0108] For example, in some embodiments, the second bracket 600 is made of stainless steel.

[0109] It should be noted that the compressor 300 can be a fixed-frequency compressor 300 or a variable-frequency compressor 300. When the compressor 300 is a fixed-frequency compressor 300, the volume of the electronic control component 500 can be greatly reduced, thereby directly saving the layout of the electronic control.

[0110] The air-conditioning outdoor unit provided in the embodiment of the present application realizes the separate arrangement of the electronic control component 500, the compressor 300 and the heat exchanger 200 through the setting of the above-mentioned electronic control component 500, reduces the mutual interference between the electronic control component 500, the compressor 300 and the heat exchanger 200, and the installation and disassembly process does not involve other components such as the wiring structure 400, thereby reducing the use of connectors, thereby reducing production costs and simplifying the assembly process.

[0118] The air-conditioning outdoor unit provided in the embodiment of the present application realizes indirect assembly between the electronic control component 500 and the base 110 through the arrangement of the above-mentioned bracket body 610 and the support frame 620. Compared with the solution in which the electronic control component 500 is directly fixed to the third surface 123, the overall structural strength and reliability of the casing are improved, and at the same time, the compressor 300 and the electronic control component 500 are separated to prevent mutual collision and safety accidents.

[0121] Specifically, the high-pressure valve 710 can be connected between the outlet of the compressor 300 and the gas-liquid separator of the air conditioner indoor unit, and the low-pressure valve 720 can be connected between the inlet of the compressor 300 and the multi-way reversing valve of the air conditioner indoor unit.

[0122] In this embodiment, if Figure 1-Figure 3 As shown, the third bracket 800 can be in the shape of a plate, the third bracket 800 can be embedded in the fourth surface 124 of the side panel 120, or the third bracket 800 can be fitted with the inner side of the fourth surface 124, the high-pressure valve 710 and the low-pressure valve 720 can be installed on the outside of the third bracket 800 in the vertical direction, specifically, the high-pressure valve 710 can be arranged above the low-pressure valve 720, the valve cover 900 can be in the shape of a square cover, the valve cover 900 and the third bracket 800 can be covered to form a second accommodating cavity, and the high-pressure valve 710 and the low-pressure valve 720 can be accommodated in the second accommodating cavity.

[0123] Among them, the third bracket 800 can be made of metal material or plastic material, among which the metal material can include but is not limited to stainless steel, aluminum alloy or titanium alloy, and the plastic material can include but is not limited to PS (Polystyrene), PP (polypropylene) or PC (Polycarbonate), etc., and there is no restriction here.

[0124] For example, in some embodiments, the third bracket 800 is made of PS (Polystyrene).

[0125] The connection method between the third bracket 800 and the fourth surface 124 of the side panel 120 may include, but is not limited to, bolt connection, riveting, or snap connection, etc., which is not limited here.

[0126] For example, in some embodiments, the third bracket 800 and the fourth surface 124 of the side panel 120 are connected by bolts.

[0127] The connection method between the third bracket 800 and the high-pressure valve 710 and the low-pressure valve 720 may include but is not limited to bolt connection, riveting or snap connection, etc., which is not limited here.

[0128] For example, in some embodiments, the third bracket 800 is connected to the high-pressure valve 710 and the low-pressure valve 720 by bolt connection.

[0129] The connection method between the third bracket 800 and the valve cover 900 may include, but is not limited to, bolt connection, riveting, or snap connection, etc., which is not limited here.

[0130] For example, in some embodiments, the third bracket 800 and the valve cover 900 are connected by bolts.

[0131] The air-conditioning outdoor unit provided in the embodiment of the present application realizes the separate arrangement of the high-pressure valve 710, the low-pressure valve 720, the third bracket 800 and the valve cover 900 through the arrangement of the above-mentioned high-pressure valve 710, the low-pressure valve 720, the electronic control component 500 and the wiring structure 400, reduces the mutual interference between the high-pressure valve 710, the low-pressure valve 720, the electronic control component 500 and the wiring structure 400, and hides the high-pressure valve 710 and the low-pressure valve 720 in the second accommodating cavity, thereby forming a protective effect on the high-pressure valve 710 and the low-pressure valve 720 while preventing the high-pressure valve 710 and the low-pressure valve 720 from being exposed, which leads to accelerated aging and corrosion, thereby extending the service life of the high-pressure valve 710 and the low-pressure valve 720.

[0132] In some embodiments, as Figure 1-Figure 3 As shown, the air-conditioning outdoor unit may further include a wiring structure 400, an electronic control component 500, a high-pressure valve 710 and a low-pressure valve 720, and the side panel 120 may include first to fourth surfaces 124, the first surface 121 and the second surface 122 may be arranged opposite to each other, the third surface 123 and the fourth surface 124 may be arranged opposite to each other, the first surface 121, the third surface 123, the second surface 122 and the fourth surface 124 may be connected end to end in sequence, the wiring structure 400 may be connected to the first surface 121, the electronic control component 500 may be arranged on the third surface 123, the high-pressure valve 710 and the low-pressure valve 720 may be connected to the fourth surface 124, and the first port 230 of the second pipe may be arranged close to the fourth surface 124.

[0133] like Figure 1-Figure 3 As shown, the side panel 120 may include four side panels, each of which has the above-mentioned first to fourth surfaces 124. The wiring structure 400 and the electronic control component 500 may be separated and arranged on two adjacent surfaces, the wiring structure 400 and the high-pressure valve 710 may be separated and arranged on two adjacent surfaces, and the electronic control component 500 and the high-pressure valve 710 may be separated and arranged on two opposite surfaces. By reasonably dividing the space above the heat exchanger 200, the wiring structure 400, the electronic control component 500 and the high-pressure valve 710 may respectively occupy different sides of the upper space, so that the installation and disassembly of the wiring structure 400, the electronic control component 500 and the high-pressure valve 710 are more independent, reducing mutual interference, and maximizing the use of the free space in the casing, thereby realizing a highly integrated small-volume layout of the air-conditioning outdoor unit.

[0134] like Figure 1-Figure 2 As shown, the air-conditioning outdoor unit may further include a flow valve 730, which may be installed in the first accommodating chamber and connected to the second port 240 of the second pipe. The first port 230 and the second port 240 may be arranged on the same side, that is, the water inlet valve of the first port 230 and the flow valve 730 of the second port 240 may be designed on the same side. The air-conditioning outdoor unit may be installed Figure 1The right side shown in the figure is placed against the wall, which makes it easier for the second pipe to drain and inlet water.

[0135] Furthermore, the first port 230 of the second pipe can be designed on the same side of the third bracket 800. In other words, the first port 230 of the second pipe can be arranged and designed close to the high-pressure valve 710 and the low-pressure valve 720, so as to facilitate relevant operators to connect the refrigerant pipe and the water pipe on the same side.

[0136] The application also discloses a kitchen air conditioning system.

[0137] In some embodiments, the kitchen air conditioning system includes: an air conditioning indoor unit and any one of the air conditioning outdoor units described above.

[0138] The air conditioner indoor unit is connected to the air conditioner outdoor unit.

[0139] The installation location of the air conditioner outdoor unit can include but is not limited to the kitchen cabinet, kitchen wall, living balcony or shared outdoor unit position, etc., which is not restricted here.

[0140] The kitchen air-conditioning system provided in the embodiment of the present application, through the setting of the above-mentioned air-conditioning outdoor unit, greatly reduces the volume of the air-conditioning outdoor unit without affecting the cooling capacity of the kitchen air-conditioning system, improves the integration of the air-conditioning outdoor unit, thereby realizing the overall miniaturization and lightweight design of the air-conditioning outdoor unit, and at the same time solves the problem of the kitchen air-conditioning system having no outdoor unit installation position, thereby meeting the needs of installing the air-conditioning outdoor unit in multiple locations such as the kitchen, living balcony or shared outdoor unit position.

[0141] In summary, based on the above-mentioned kitchen air conditioning system, six sets of test data during actual operation are provided below to demonstrate the significant effects of the embodiments of the present application, as shown in Table 1 below.

[0144] As can be seen from Table 1, the cooling capacity of each of the 6 groups of data is above 3500W. Therefore, the kitchen air-conditioning system provided in this application can achieve a cooling capacity of at least 3500W in actual operation when using the above-mentioned small-volume structural design. The entire kitchen air-conditioning system not only achieves a miniaturized design, but also takes into account the cooling capacity requirements of the kitchen air-conditioning.

[0145] It should be noted that the volume of the kitchen air-conditioning system provided in this application can basically reach 26L after the product is put into use.
