DETAILED DESCRIPTION

[0037] In order to make the purpose and implementation method of the present application clearer, the exemplary implementation method of the present application will be clearly and completely described below in conjunction with the drawings in the exemplary embodiments of the present application. Obviously, the described exemplary embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0038] In the description of the present application, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0039] The terms "first", "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0040] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0041] The air conditioner in this application performs a refrigeration cycle of the air conditioner by using a compressor, a condenser, an expansion valve and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion and evaporation, and supplies refrigerant to the air that has been conditioned and heat-exchanged.

[0042] The compressor compresses the refrigerant gas in a low temperature and low pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0043] The expansion valve expands the high-temperature and high-pressure liquid refrigerant condensed in the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a refrigeration effect by utilizing the latent heat of evaporation of the refrigerant to exchange heat with the material to be cooled. In the entire cycle, the air conditioner can adjust the temperature of the indoor space.

[0044] The outdoor unit of the air conditioner refers to a portion of a refrigeration cycle including a compressor and an outdoor heat exchanger, the indoor unit of the air conditioner includes an indoor heat exchanger, and an expansion valve may be provided in the indoor unit or the outdoor unit.

[0045] The indoor heat exchanger and the outdoor heat exchanger function as a condenser or an evaporator. When the indoor heat exchanger functions as a condenser, the air conditioner functions as a heater in a heating mode, and when the indoor heat exchanger functions as an evaporator, the air conditioner functions as a cooler in a cooling mode.

[0046] Reference Figures 1 to 3The air conditioner according to the embodiment of the present application includes an outdoor unit installed in an outdoor space, and the outdoor unit is connected to an indoor unit (not shown) installed in an indoor space through a pipe. The outdoor unit may be provided with a compressor, an outdoor heat exchanger, an outdoor fan, an expander and similar components of a refrigeration cycle, and the indoor unit may also be provided with an indoor heat exchanger and an indoor fan.

[0047] The outdoor unit includes a housing 10, in which a plurality of components constituting a refrigeration cycle are installed. The housing 10 includes a top cover 11 defining a top structure, a bottom plate defining a bottom structure, and four side plates connected between the top cover 11 and the bottom plate. Among the four side plates, the side plate located at the rear side is referred to as a first side plate 13.

[0048] The top cover 11 includes a top wall and side walls connected around the top wall. For example, the top cover 11 has a first side wall and a second side wall arranged opposite to each other in the front-back direction, and a third side wall and a fourth side wall arranged opposite to each other in the left-right direction. The top cover 11 is covered at the top ends of the four side walls.

[0049] An air inlet 30 is disposed on the first side plate 13 , and the air inlet 30 can expose most of the heat exchanger 20 .

[0050] A heat exchanger 20 is installed in the housing 10 . The heat exchanger 20 is disposed corresponding to the air inlet 30 . The heat exchanger 20 performs heat exchange with the air sucked in through the air inlet 30 .

[0051] When the air conditioner is in cooling operation in hot weather, water is usually sprayed onto the heat exchanger 20 to achieve evaporative cooling. Therefore, the outdoor unit further includes a spray device 100 for spraying water onto the heat exchanger 20 from the air inlet 121 .

[0052] Reference Figures 4 to 6 The spray device 100 includes a spray box 110 and a control device.

[0053] The spray box 110 is in the shape of a rectangular parallelepiped box, and the spray box 110 is installed on the housing 10. The spray box 110 can be installed on the top cover 11 of the housing 10, or the spray box 110 can be installed on the side panel of the housing 10, or the spray box 110 can be installed on the wall.

[0054] In some embodiments, the spray box 110 includes a base 111 and a box body 112. The base 111 is connected to the top cover 11, and the box body 112 is connected to the base 111, and a receiving space is enclosed between the box body 112 and the base 111.

[0055] The control device is disposed in the accommodation space of the spray box 110. For example, the control device may be connected to the base 111.

[0056] The control device is used to realize the electrical control function of the spray, wherein the control device comprises a control component 120 and a water circuit switch.

[0057] The control assembly 120 includes a card seat 121 and a control board 122. The card seat 121 is in a box shape with an upper end open, and the control board 122 is connected to the card seat 121. The card seat 121 accommodates the control board 122, and the control board 122 is installed in the spray box 110 by connecting the card seat 121 to the base 111.

[0058] The control panel 122 is electrically connected to the power line and communication line of the outdoor unit. According to the changes in the ambient temperature and the set control logic, it controls the opening and closing of the spray and the spraying time, thereby achieving the purpose of spraying water to cool the heat exchanger 20 and improving the cooling capacity of the air conditioner in a high temperature environment.

[0059] The water circuit switch can be, for example, a water circuit solenoid valve 140, which is connected to the spray box 110 and is used to switch the water circuit on and off. When the spray function is turned on, the water circuit solenoid valve 140 is opened to connect the water circuit; when the spray function is turned off, the water circuit solenoid valve 140 is closed to disconnect the water circuit.

[0060] The spray device 100 further includes a water supply pipe 150 and a nozzle assembly 130 .

[0061] The water supply pipe 150 is disposed in the spray box 110 , one end of the water supply pipe 150 is connected to a water supply connector 151 , and the water supply connector 151 is exposed outside the spray box 110 and is used to connect to the water supply pipe. The other end of the water supply pipe 150 is connected to the water inlet end of the water circuit solenoid valve 140 .

[0062] The water outlet of the water circuit electromagnetic valve 140 is connected to the nozzle assembly 130. The nozzle 131 of the nozzle assembly 130 is exposed outside the spray box 110.

[0063] The water circuit solenoid valve 140 is electrically connected to the control board 122 to control the opening and closing of the water circuit solenoid valve 140 .

[0064] When the spray function is turned on, the electronic control system controls the water circuit solenoid valve 140 to open, and the external water source is supplied to the nozzle assembly 130 through the water supply pipe 150, and the nozzle 131 of the nozzle assembly 130 sprays water to the heat exchanger 20. When the spray function is turned on and off, the electronic control system controls the water circuit solenoid valve 140 to close, and the water circuit is disconnected.

[0065] In some embodiments, a partition 113 may be provided in the spray box 110 , and the partition 113 divides the accommodation space into two spaces, namely a first cavity 1102 and a second cavity 1103 .

[0066] Specifically, the partition 113 has a vertically extending plate body, and the bottom end of the plate body has a transversely extending flange, which abuts against the base 111 and can be fixedly connected to the base 111 by welding or screw connection.

[0067] The control component 120 is disposed in the first chamber 1102 , and the water supply pipe 150 , the water circuit solenoid valve 140 , etc. are disposed in the second chamber 1103 .

[0068] In the present application, the control component 120 is separated from the waterway by the partition 113. When an unexpected situation such as water leakage occurs in the waterway, the partition 113 can play a certain blocking role on the water leaked from the waterway, so as to prevent the water in the second chamber 1103 from flowing into the first chamber 1102, thereby preventing the water from contacting the control component 120.

[0069] The partition plate 113 may be connected to a rubber ring 114 , and the wires of the water circuit solenoid valve 140 may pass through the rubber ring 114 to the second chamber 1103 to be connected to the control board 122 .

[0070] In some embodiments, reference Figure 7 The base 111 is connected with a mounting bracket 115, and the control assembly 120 is connected to the mounting bracket 115. The mounting bracket 115 can raise the height of the control assembly 120, so that since the control assembly 120 is at a high position, even if the water leaked from the waterway enters the first chamber 1102, the water can still be prevented from contacting the control assembly 120 to a certain extent.

[0071] Specifically, the mounting bracket 115 is roughly "U"-shaped, including a first wall 1151, a second wall 1152 and a third wall 1153, the second wall 1152 and the third wall 1153 extend roughly vertically, and the first wall 1151 is connected between the top of the second wall 1152 and the top of the third wall 1153.

[0072] Reference Figure 5 and Figure 7 The control component 120 is connected to the first wall 1151 . Specifically, the holder 121 of the control component 120 is connected to the first wall 1151 via screws, thereby achieving installation of the control component 120 on the mounting bracket 115 .

[0073] The bottom ends of the second wall 1152 and the third wall 1153 respectively have flanges extending away from each other, and the flanges can be connected to the base 111 by welding or screws.

[0074] Reference Figure 4 and Figure 5The first cavity 1102 and the second cavity 1103 can be arranged in the front-to-back direction, with the first cavity 1102 close to the front side and the second cavity 1103 close to the rear side (i.e., close to the side of the air inlet 30). The water channel is arranged on the side of the spray box 110 close to the air inlet 30, which can reduce the length of the water channel.

[0075] In some embodiments, reference Figures 7 to 9 The base 111 is provided with a slot 1113, and the bottom end of the water circuit electromagnetic valve 140 corresponds to the slot 1113. The fixing plate 116 abuts against the outer bottom surface of the base 111, and is connected to the water circuit electromagnetic valve 140 through screws at the slot 1113.

[0076] In the present application, the groove 1113 has a positioning function for the water circuit solenoid valve 140, that is, it can limit the lateral movement of the water circuit solenoid valve 140. By limiting the water circuit solenoid valve 140 through the groove 1113, the number of screws used when connecting the water circuit solenoid valve 140 can be reduced, and the assembly efficiency can be improved. It has the advantages of simple installation and high assembly efficiency.

[0077] According to an embodiment of the present application, the opposite sides of the slot 1113, for example Figure 8 The left and right ends of the slot 1113 are provided with limiting parts 1114 extending toward the fixing plate 116, and the bottom of the water circuit electromagnetic valve 140 is stuck between the two limiting parts 1114. The setting of the limiting parts 1114 can increase the limiting area of ​​the slot 1113 on the water circuit electromagnetic valve 140 and increase the reliability of the limiting.

[0078] In some embodiments, the fixing plate 116 is generally "U"-shaped, and the two side walls of the fixing plate 116 abut against the limiting portion 1114 from the left and right sides, that is, the limiting portion 1114 is inserted into the cavity of the fixing plate 116. The limiting portion 1114 can limit the left and right movement of the fixing plate 116, and the connection firmness of the fixing plate 116 can be ensured by only one screw.

[0079] In some embodiments, continue to refer to Figure 6 and Figure 7 The spray device 100 further includes a wire clamp 152, which clamps the water supply pipe 150 from the upper side and is connected to the base 111. The wire clamp 152 can limit the movement of the water supply pipe 150 to prevent the water supply pipe 150 from being pulled by the water supply pipe and moving.

[0080] Specifically, the wire clamp 152 includes two laterally extending straight pieces 1521 and an arc-shaped hoop 1522 connected between the two straight pieces 1521. The hoop 1522 is clamped outside the water supply pipe 150, and the straight piece 1521 abuts against the base 111 and is connected to the base 111 by screws.

[0081] The spray device 100 intermittently sprays water to the heat exchanger 20 of the outdoor unit, using the sensible heat and latent heat of water to improve the heat exchange performance of the heat exchanger 20, reduce the condensation pressure, and enable the unit to obtain higher cooling capacity and energy efficiency. The parameters of the nozzle 131 in the spray device 100 have a great influence on the spray effect.

[0082] In some embodiments, reference Figure 4 and Fig. 9 The base 111 includes a base body portion 1111 and a guide rail portion 1112 .

[0083] The base body 1111 is plate-shaped, and the box body 112 is connected to the base body 1111 by screws. The guide rails 1112 are connected to two opposite ends of the base body 1111 .

[0084] The guide rail portion 1112 includes a first guide rail portion and a second guide rail portion that are opposite to each other. For example, the first guide rail portion is located at the left end of the base body portion 1111, and the second guide rail portion is located at the right end of the base body portion 1111. The first guide rail portion and the second guide rail portion are both "L"-shaped, the first guide rail portion and the base body portion 1111 form a "U"-shaped groove, and the second guide rail portion and the base body portion 1111 form a "U"-shaped groove, and the openings of the left and right "U"-shaped grooves are opposite to each other.

[0085] Specifically, the left end of the base body 1111 is first bent downward and then bent to the right to form a first guide rail portion, and the right end of the base body 1111 is first bent downward and then bent to the left to form a second guide rail portion.

[0086] Reference Figure 5 and Fig.16 The spray box 110 further includes a bracket 117, which is located at the bottom of the box body 112 and connected to the guide rail 1112. For example, the bracket 117 is inserted into the guide rail 1112, the bracket 117 is connected to the guide rail 1112, and then when the spray device 100 is installed and used, the bracket 117 is connected to the housing 10, or the bracket 117 is connected to the wall, thereby achieving the installation of the spray box 110.

[0087] According to air conditioners of different sizes or different usage scenarios, the installation requirements can be met by replacing the bracket 117.

[0088] In some embodiments, reference Fig.10 and Fig.11 The guide rail portion 1112 is provided with a long adjustment slot 1115, and the length extension direction of the adjustment slot 1115 is the same as the extension direction of the guide rail portion 1112. The bracket 117 is provided with a first screw mounting hole 1171, and the fastener is inserted through the adjustment slot 1115 and the first screw mounting hole 1171.

[0089] Since the bracket 117 is inserted into the guide rail portion 1112 , the position of the bracket 117 relative to the base 111 can be adjusted by adjusting the dimension of the bracket 117 extending into the guide rail portion 1112 , thereby meeting the installation requirements of different models.

[0090] The adjusting groove 1115 may be in the shape of a waist-shaped groove, and the two ends of its length are in arc shape. In addition, in other embodiments, the adjusting groove 1115 may also be arranged on the base body 1111.

[0091] A circular hole may also be provided on the guide rail portion 1112 , and correspondingly, a screw mounting hole corresponding to the circular hole is provided on the bracket 117 , and the circular hole of the guide rail portion 1112 is connected to the screw mounting hole of the bracket 117 by screws passing through the circular hole.

[0092] In some embodiments, reference Fig.11 and Fig.12 The spray box 110 is mounted on the top cover 11. The bracket 117 includes a plug-in portion 1172 plugged into the guide rail portion 1112, and a fixing portion 1173 for connecting to the top cover 11. The plug-in portion 1172 and the fixing portion 1173 are connected to form an "L" shape, and the fixing portion 1173 extends vertically and is connected to the side wall of the top cover 11.

[0093] Combination Figures 10 to 12 The bracket 117 includes a first bracket 1174 and a second bracket 1175. The first bracket 1174 and the second bracket 1175 are respectively connected to opposite ends of the guide rail portion 1112. For example, the guide rail portion 1112 extends in the front-to-back direction, the first bracket 1174 is connected to the front end of the guide rail portion 1112, and the second bracket 1175 is connected to the rear end of the guide rail portion 1112.

[0094] The first bracket 1174 and the second bracket 1175 clamp the top cover 11 from the front-to-back direction. Specifically, the fixing portion 1173 of the first bracket 1174 can abut against the front side wall of the top cover 11, and the fixing portion 1173 of the second bracket 1175 can abut against the rear side wall of the top cover 11.

[0095] When the air conditioner is relatively large, that is, the width (front-to-back direction) of the air conditioner is relatively large, the distance between the fixing portion 1173 of the first bracket 1174 and the fixing portion 1173 of the second bracket 1175 needs to be relatively large. At this time, the position of the second bracket 1175 can be kept stationary, and the position of the first bracket 1174 can be adjusted: the first bracket 1174 is moved to the front side so that the size of the first bracket 1174 extending into the guide rail portion 1112 is reduced, thereby increasing the distance between the first bracket 1174 and the second bracket 1175 to match the width of the top cover 11.

[0096] Alternatively, the position of the first bracket 1174 can be kept stationary and the position of the second bracket 1175 can be adjusted: the second bracket 1175 can be moved rearward so that the size of the second bracket 1175 extending into the guide rail portion 1112 is reduced, thereby increasing the distance between the first bracket 1174 and the second bracket 1175.

[0097] Alternatively, the positions of the first bracket 1174 and the second bracket 1175 can be adjusted: the first bracket 1174 can be moved to the front side so that the dimension of the first bracket 1174 extending into the guide rail portion 1112 is reduced, and the second bracket 1175 can be moved to the rear side so that the dimension of the second bracket 1175 extending into the guide rail portion 1112 is reduced, thereby increasing the distance between the first bracket 1174 and the second bracket 1175.

[0098] In some embodiments, since the nozzle assembly 130 is connected to the rear end of the spray box 110, the second bracket 1175 is also located at the rear end of the spray box 110. If the second bracket 1175 is adjusted too far backward, it will touch the nozzle assembly 130. Therefore, the adjustment slot 1115 of the second bracket 1175 corresponding to the rear end of the base 111 can be set relatively small. In this way, the second bracket 1175 can be adjusted in a relatively small range of sizes, which can avoid interference with the nozzle assembly 130.

[0099] In addition, the requirements of different machine sizes can be met by replacing the bracket 117. For example, brackets 117 of corresponding sizes are designed for different models of air conditioners. During installation, you only need to select an appropriate bracket 117 according to the model.

[0100] In the present application, the spray box 110 can be installed on the air conditioner to adapt to different models of air conditioners by adjusting the position of the bracket 117 relative to the base 111 or replacing the corresponding bracket 117, thereby avoiding the trouble of designing spray boxes 110 of different sizes for different air conditioners, saving costs, and expanding the installation range of the spray device 100.

[0101] According to an embodiment of the present application, the first bracket 1174 is fastened to the front side wall of the top cover 11 by screws, thereby achieving connection between the first bracket 1174 and the top cover 11.

[0102] Reference Figures 10 to 13 A second screw mounting hole 1179 is provided on the fixing portion 1173 of the first bracket 1174 , and a screw passes through the second screw mounting hole 1179 to be connected to the side wall of the top cover 11 .

[0103] A hook portion 1176 is provided at the bottom end of the fixing portion 1173 of the second bracket 1175 , and the hook portion 1176 hooks the bottom end of the top cover 11 , thereby achieving connection between the second bracket 1175 and the top cover 11 .

[0104] The second bracket 1175 is hooked with the top cover 11 through the hook portion 1176, which can save the use of screws. It is only necessary to hook the second bracket 1175 onto the top cover 11, thereby improving the convenience of operation and the efficiency of disassembly and assembly.

[0105] According to the embodiments of the present application, referring to Fig.14 The bracket 117 includes a bracket body 1177, which is in an "L" shape. The left and right sides of the upper end of the bracket body 1177 have upwardly extending flange portions 1178, and the first screw mounting hole 1171 is provided on the flange portion 1178.

[0106] In some embodiments, since the space above the air conditioner is limited, that is, there is not enough space above the air conditioner to accommodate the spray box 110, the spray box 110 may be installed on the wall.

[0107] Specifically, refer to Fig.15 , install the nozzle assembly 130 to the rear end of the top cover 11, and then connect the extension water pipe ( Fig.15 The middle dotted line indicates the extension of the water pipe).

[0108] In this embodiment, refer to Fig.16 and Fig.17 The bracket 117 is plate-shaped and can be divided into a plug-in portion 1172 and a fixing portion 1173. The plug-in portion 1172 is a portion inserted into the guide rail portion 1112, and the fixing portion 1173 is a portion exposed from the guide rail portion 1112. The bracket 117 is fixed to the base 111 using screws, and then the bracket 117 is fixed to the wall using wall nails, so that the spray box 110 is installed on the wall.

[0109] In the present application, by pulling out the bracket 117, adjusting the position of the bracket 117 relative to the base 111, or replacing the bracket 117 of different sizes, the requirements of different installation sizes of the spray box 110 on the wall can be met, thereby improving the versatility of installation and use of the spray box 110.

[0110] According to an embodiment of the present application, the bracket 117 includes a bracket body 1177 , which is plate-shaped. The left and right sides of the bracket body 1177 have flange portions 1178 extending upward, and the first screw mounting hole 1171 is provided on the flange portion 1178 .

[0111] The spray device 100 intermittently sprays water to the heat exchanger 20 of the outdoor unit, using the sensible heat and latent heat of water to improve the heat exchange performance of the heat exchanger 20, reduce the condensation pressure, and enable the unit to obtain higher cooling capacity and energy efficiency. The parameters of the nozzle 131 in the spray device 100 have a great influence on the spray effect.

[0112] Among the parameters of the nozzle 131, the spraying distance of the nozzle 131 has a greater influence on the overall capacity. The spraying distance can be designed according to the size of the heat exchanger 20. The larger the spraying distance, the larger the spraying area of ​​the heat exchanger 20, and the more obvious the improvement effect of the overall capacity. While increasing the spraying area, it should also be avoided that water is sprayed outside the heat exchanger to reduce the utilization rate of water, or splashed to the neighbors' homes to cause complaints.

[0113] Therefore, in the present application, the spray distance of the nozzle 131 and the size of the heat exchanger 20 are set: the parameters of the nozzle 131: the spray area is recorded as S, the spray width is recorded as L; the area of ​​the exposed part of the heat exchanger 20 at the air inlet 30 is M. The relationship between the spray area S and M of the nozzle 131 satisfies: S = (85% ~ 95%) M; refer to Figure 2 , a distance W1 from the center of the nozzle 131 to the right end of the first side plate 13>1 / 2L, and a distance W2 from the center of the nozzle 131 to the left end of the first side plate 13>1 / 2L.

[0114] S=(85%~95%)M, the spraying effect is ensured by the spraying area, W1>1 / 2L, W2>1 / 2L can prevent the spraying water from spraying outside the casing 10, avoiding water waste while ensuring that the water will not splash to the neighbor's house.

[0115] According to the embodiments of the present application, referring to Figure 6 The nozzle assembly 130 includes a supporting water pipe 132 , one end of the supporting water pipe 132 is connected to the water outlet end of the water circuit solenoid valve 140 , and the other end of the supporting water pipe 132 is connected to the nozzle 131 .

[0116] Reference Fig.18 and Fig.19 The nozzle 131 can be a fan-shaped nozzle, and the nozzle 131 is cylindrical. A nozzle 1311 is provided on the cylindrical side of the nozzle 131, and the shape of the nozzle 1311 is a fan-shaped fan surrounded by a plane 1312 and an arc surface 1313, and the plane 1312 is perpendicular to the axis of the nozzle 131.

[0117] In some embodiments, the exposed width W of the heat exchanger 20 is greater than or equal to 637 mm, the radius R of the arc surface 1313 is 5.5 to 7.5 mm; the outlet direction of the arc surface 1313 is ( Fig.19 The direction indicated by the hollow arrow, i.e., the tangent direction of the arc end, is perpendicular to the axis of the nozzle 131, and the maximum axial length L of the nozzle 1311 on the cylindrical surface is R.

[0118] Under the condition of this size, the nozzle 1311 of the nozzle 131 will not cause too little improvement in the capacity of the heat exchanger due to a small spraying range, nor will the spray splash outside the heat exchanger or even outside the casing due to an excessively large spraying range.

[0119] Therefore, under this size condition, the spraying range can be guaranteed, thereby improving the overall capacity of the machine, and splashing will not occur on the left and right sides of the heat exchanger 20.

[0120] The aperture size of the nozzle, that is, the aperture d of the water spray hole, is a key dimension that affects the amount of water sprayed. The amount of water sprayed by the nozzle should be reduced as much as possible while meeting the capacity of the entire machine to reduce the user's cost of use. A small nozzle aperture is prone to the risk of scaling, and scaling of the nozzle should be avoided to affect the spraying effect. Therefore, in this application, the aperture d of the water spray hole is set to 1.5~1.7mm, which reduces the aperture as much as possible while ensuring the spraying effect, and the risk of scaling is relatively low at this aperture.

[0121] Exemplarily, the radius R of the arc surface 1313 is 6.5 mm, the maximum axial length of the nozzle 1311 on the cylindrical surface is L=6.5 mm, and the aperture d of the water spray hole is 1.6 mm.

[0122] According to the embodiment of the present application, the lowest end of the nozzle 1311 is not higher than the top of the air inlet 30, which can reduce or even avoid the splashing of the spray water at the top.

[0123] Combination Figure 3 The supporting water pipe 132 includes a first pipe 1321 and a second pipe 1322 connected at an angle, the first pipe 1321 extends horizontally, and the second pipe 1322 extends obliquely toward the rear and lower part of the casing 10, and the end of the second pipe 1322 is connected to the nozzle 131, and the angle α between the second pipe 1322 and the first pipe 1321 is 120°~140°.

[0124] In some application scenarios, the upper space of the outdoor unit is limited and cannot accommodate the entire spray box 110. In this case, the spray box 110 can be installed on the wall of the application scenario, and the position of the nozzle assembly 130 remains unchanged and is still located on the top cover of the outdoor unit.

[0125] In some embodiments, reference Fig.15 and Fig. 20 The spray device 100 includes a fixing bracket 160 and a pipe joint 170 . The fixing bracket 160 is connected to the rear end of the top cover 11 , and the pipe joint 170 is installed on the fixing bracket 160 .

[0126] Reference Fig. 20 and Fig.21 The pipe joint 170 includes a nozzle joint 171 and a water supply joint 172. The nozzle assembly 130 is connected to the nozzle joint 171, and the water supply joint 172 is used to connect an extended water pipe, and the other end of the extended water pipe is connected to the water circuit solenoid valve 140 in the spray box 110.

[0127] According to the embodiments of the present application, referring to Fig.15 , Figure 20 to Figure 22The fixing bracket 160 includes a fixing portion 161 and a supporting portion 162. The fixing portion 161 is used to be connected to the top cover 11, and the supporting portion 162 is connected to the upper end of the fixing portion 161.

[0128] The support portion 162 is provided with a mounting portion 163 , and the pipe joint 170 is inserted into the mounting portion 163 .

[0129] Specifically, the mounting portion 163 is groove-shaped and has an opening at the rear end. The pipe joint 170 is inserted into the mounting portion 163 from the rear side. The mounting portion 163 can limit the pipe joint 170, and then the pipe joint 170 is fixed to the support portion 162 by fasteners.

[0130] The present application sets a fixed bracket 160 connected to the top cover 11, and the nozzle assembly 130 is fixed by the fixed bracket 160. The fixed bracket 160 is relatively small and occupies a relatively small space. In the scenario where the top space of the outdoor unit is limited, the spray device 100 can also be installed on the outdoor unit.

[0131] In some embodiments, the nozzle joint 171 and the water supply joint 172 are arranged at an angle, for example, the axis of the nozzle joint 171 is parallel to the front-to-back direction, and the axis of the water supply joint 172 is parallel to the left-to-right direction.

[0132] The pipe joint 170 further includes a connecting portion 173, which is connected to the front end of the nozzle joint 171. The nozzle joint 171, the water supply joint 172, and the connecting portion 173 are generally in a "T" shape.

[0133] The side wall forming the mounting portion 163 is provided with an escape portion 164, which is groove-shaped, and the connecting portion 173 is plugged into the mounting portion 163, and the water supply connector 172 of the pipe connector 170 corresponds to the escape portion 164. The connecting portion 173 is connected to the supporting portion 162 of the fixing bracket 160, so that the pipe connector 170 is installed on the fixing bracket 160.

[0134] The opening of the escape portion 164 faces the rear side, that is, the water supply joint 172 of the pipe joint 170 enters the escape portion 164 from the rear side.

[0135] The mounting portion 163 limits the connection portion 173 of the pipe joint 170 in the left-right direction, and the avoidance portion 164 limits the water supply joint 172 in the up-down direction. The connection portion 173 is connected to the support portion 162 by bolts, which can limit the movement of the pipe joint 170 in the front-back direction.

[0136] In the present application, by limiting the connection part 173 by the installation part 163 and limiting the water supply connector 172 by the avoidance part 164, the number of fasteners used when connecting the pipe connector 170 to the fixed bracket 160 can be reduced, thereby improving assembly efficiency.

[0137] In the present application, the avoidance portion 164 is used to limit the position of the pipe joint 170 and the position of the fastener, forming a lever limiting structure, which forms effective limits in all directions after the pipe joint 170 is installed, thereby ensuring the position of the nozzle 131.

[0138] In some embodiments, the support portion 162 includes two support arms disposed in parallel and spaced apart from each other, and the two support arms are respectively a first support arm 1621 and a second support arm 1622 .

[0139] The space between the first supporting arm 1621 and the second supporting arm 1622 forms a mounting portion 163 , and the avoidance portion 164 is disposed on the second supporting arm 1622 .

[0140] In other embodiments, the first support arm 1621 and the second support arm 1622 are both provided with an avoidance portion 164 , and the avoidance portion 164 penetrates through the first support arm 1621 and the second support arm 1622 at the same time.

[0141] In this way, the water supply connector 172 of the pipe connector 170 may correspond to the avoidance portion 164 of the first support arm 1621 , and may also correspond to the avoidance portion 164 of the second support arm 1622 .

[0142] Specifically, the first support arm 1621 and the second support arm 1622 extend roughly vertically, with the first support arm 1621 located on the left and the second support arm 1622 located on the right, and the front end, rear end and upper end of the mounting portion 163 formed by them are open. Therefore, after the connecting portion 173 of the pipe joint 170 is inserted into the mounting portion 163, the first support arm 1621 and the second support arm 1622 can limit the left and right movement of the pipe joint 170.

[0143] The escape portion 164 is a "U"-shaped groove, including an upper side wall, a lower side wall and a bottom wall, and the opening of the "U"-shaped groove faces backward. The escape portion 164 is used to avoid the installation of the water supply connector 172.

[0144] According to an embodiment of the present application, the fixing portion 161 includes a first fixing arm 1611 and a second fixing arm 1612; the first fixing arm 1611 and the second fixing arm 1612 are "L" shaped. The first fixing arm 1611 extends vertically, and the second fixing arm 1612 extends horizontally.

[0145] The first fixing arm 1611 is connected to the rear side wall of the top cover 11. Specifically, the first fixing arm 1611 can be connected to the top cover 11 by at least three screws. The second fixing arm 1612 abuts against the upper end of the top cover 11, thereby achieving the connection of the fixing bracket 160 on the top cover 11.

[0146] The first supporting arm 1621 is connected to the left end of the second fixing arm 1612 , and the second supporting arm 1622 is connected to the right end of the second fixing arm 1612 .

[0147] The fixing bracket 160 is a sheet metal part, the first fixing arm 1611 is formed by bending the rear end of the second fixing arm 1612 downward, the first supporting arm 1621 is formed by bending the left end of the second fixing arm 1612 upward, and the second supporting arm 1622 is formed by bending the right end of the second fixing arm 1612 upward.

[0148] In some embodiments, the support arm has at least one transverse bend, and the bend is located below the avoidance portion 164, so as to utilize the bend structure to achieve structural reinforcement.

[0149] Specifically, the support arm includes a connecting portion 1623, a horizontal arm portion 1624 and a vertical arm portion 1625. The bottom end of the connecting portion 1623 is connected to the fixing portion 161, the horizontal arm portion 1624 is formed by the top end of the connecting portion 1623 extending laterally, and the vertical arm portion 1625 is formed by the end of the horizontal arm portion 1624 extending upward.

[0150] The transverse arm portion 1624 of the first support arm 1621 is bent toward the second support arm 1622 , and the transverse arm portion 1624 of the second support arm 1622 is bent toward the first support arm 1621 .

[0151] The inventive concept of this application:

[0152] In the present application, the control component 120 is separated from the waterway by the partition 113. When an unexpected situation such as water leakage occurs in the waterway, the partition 113 can play a certain blocking role in the leakage, thereby preventing the water in the second chamber 1103 from flowing into the first chamber 1102, thereby avoiding the influence of water on the control component 120.

[0153] In the present application, a mounting bracket 115 is connected to the base 111, and the control assembly 120 is connected to the mounting bracket 115. The mounting bracket 115 can raise the height of the control assembly 120, so that since the control assembly 120 is in a high position, even when water leaked from the waterway enters the first chamber 1102, the water can be prevented from contacting the control assembly 120 to a certain extent.

[0154] In the present application, a groove 1113 is set on the base 111, and the water circuit solenoid valve 140 is connected to the groove 1113. The groove 1113 limits the water circuit solenoid valve 140, which can reduce the number of screws used when connecting the water circuit solenoid valve 140 and improve the assembly efficiency. The water circuit solenoid valve 140 has the advantages of simple installation and high assembly efficiency.

[0155] In the present application, the spray box 110 is installed on the air conditioner to adapt to different models of air conditioners by adjusting the position of the bracket 117 relative to the base 111 or replacing the corresponding bracket 117, thereby avoiding the trouble of designing spray boxes 110 of different sizes for different air conditioners, saving costs, and improving the installation versatility of the spray device 100.

[0156] In the present application, by pulling out the bracket 117, adjusting the position of the bracket 117 relative to the base 111, or replacing the bracket 117 of different sizes, the requirements of different installation sizes of the spray box 110 on the wall can be met, thereby improving the versatility of installation and use of the spray box 110.

[0157] In the present application, by setting the area of ​​the exposed part of the heat exchanger 20 at the air inlet 30 to M, the relationship between the spraying area S of the nozzle 131 and M satisfies: S = (85% ~ 95%) M, which can ensure the spraying effect; the distance from the center of the nozzle 131 to the left and right ends of the first side panel 13 is greater than 1 / 2L, which can prevent the spraying water from spraying outside the casing 10, thereby avoiding water waste and ensuring that the water will not splash onto the neighbors' homes.

[0158] In the present application, the exposed width W of the heat exchanger 20 is ≥ 637 mm, the radius R of the arc surface is 6.5 mm, the outlet direction of the arc surface is perpendicular to the axis of the nozzle 131, that is, the length of the nozzle 1311 on the cylindrical surface is 6.5 mm, and the aperture d of the water spray hole of the nozzle 131 is 1.6 mm. Under this size condition, the nozzle 1311 of the nozzle 131 can ensure the spray range and will not splash to the left and right sides of the heat exchanger 20.

[0159] In the present application, a fixed bracket 160 connected to the top cover 11 is provided to fix the nozzle assembly 130. The fixed bracket 160 is relatively small and occupies a relatively small space. In a scenario where the top space of the outdoor unit is limited, the spray device 100 can also be installed on the outdoor unit.

[0160] In the present application, by limiting the connection portion 173 by the installation portion 163 and limiting the water supply connector 172 by the avoidance portion 164, the number of fasteners used when connecting the pipe connector 170 to the fixed bracket 160 can be reduced, thereby improving assembly efficiency.
