[0045] Reference below Figure 1-Figure 5 A water tray assembly 100 according to an embodiment of the present invention is described.

[0046] Combination Figure 1 , Figure 2 and Figure 4 According to the utility model, the water receiving pan assembly 100 includes: a water receiving pan 110, a pumping device 120 and a heating device 130. A water receiving chamber 111 is formed on the water receiving pan 110. The water receiving chamber 111 is used to receive water from the heat exchanger. The pumping device 120 is arranged in the water receiving chamber 111, and the pumping device 120 is used to pump the water in the water receiving chamber 111 to a preset position. The heating device 130 is arranged in the water receiving chamber 111, and at least a part of the heating device 130 is arranged adjacent to the pumping device 120. Then, the distance between the above-mentioned at least part of the heating device 130 and the pumping device 120 is greater than or equal to 0; for example, the distance between the above-mentioned at least part of the heating device 130 and the pumping device 120 is less than the minimum distance between the heating device 130 and the peripheral wall of the water receiving chamber 111, so that the heating device 130 and the pumping device 120 are arranged adjacent to each other.

[0047] Specifically, when the heat exchanger is used as an evaporator, condensed water is generated on its surface. A water receiving tray 110 is provided to receive the water on the heat exchanger to prevent the water from flowing around and corroding the ground or parts around the heat exchanger. The water on the heat exchanger can flow into the water receiving chamber 111, and the pumping device 120 can pump the water in the water receiving chamber 111 to a preset position, that is, the pumping device 120 can pump the water in the water receiving chamber 111 to the outside of the water receiving chamber 111 to discharge the water in the water receiving chamber 111.

[0048] It should be noted that the "preset position" can be any position outside the water receiving chamber 111, for example, the preset position is an indoor heat exchanger, an indoor water receiving pan or an outdoor position, etc., as long as the pumping device 120 can pump the water in the water receiving chamber 111 to the outside of the water receiving pan 110. The specific preset position can be limited according to actual production requirements and heat exchange requirements, and no specific limitation is made here.

[0049] Furthermore, when the ambient temperature of the water receiving tray 110 is too low and ice appears in and / or around the pumping device 120, the heating device 130 can heat the periphery of the pumping device 120, which helps prevent ice from forming in the pumping device 120 and in part of the water receiving chamber 111 near the pumping device 120, thereby preventing the pumping device 120 from being unable to pump the water in the water receiving chamber 111, and preventing the pumping device 120 from being damaged due to operation when ice forms inside the pumping device 120, or when ice has already formed around the pumping device 120, the heating device 130 can heat to melt the ice, so that the pumping device 120 can pump out the water or recycle and reuse the water.

[0050] Optionally, the heating device 130 can be adapted to the shape of the water receiving chamber 111, which is beneficial to increase the heating area of ​​the heating device 130, thereby improving the heating effect of the heating device 130, wherein the portion of the heating device 130 close to the pumping device 120 can be arranged adjacent to the pumping device 120 to heat the periphery of the pumping device 120; or the heating device 130 can be arranged near the pumping device 120 to heat the periphery of the pumping device 120, and at the same time, on the premise of achieving heating of the periphery of the pumping device 120 to avoid freezing of the pumping device 120 or the periphery of the pumping device 120 affecting drainage and the pumping device 120, the area where the heating device 130 is arranged can be appropriately reduced, and the occupation of the internal volume of the water receiving chamber 111 by the heating device 130 is reduced, which is beneficial to increase the volume of the portion of the water receiving chamber 111 used to receive condensed water, and can be beneficial to reduce the energy consumption and production cost of the heating device 130. Of course, it can be understood that the specific arrangement of the heating device 130 can be determined according to actual production requirements, and no specific limitation is made here.

[0051] Exemplarily, when the distance between the above-mentioned at least part of the heating device 130 and the pumping device 120 is greater than 0, the distance between the above-mentioned at least part of the heating device 130 and the pumping device 120 is relatively small, for example, the distance is less than 5 cm; of course, the distance setting is not limited to this, and the distance can also be greater than or equal to 5 cm. At this time, the power required by the heating device 130 is relatively high.

[0052] Exemplarily, the entire heating device 130 is arranged adjacent to the pumping device 120, or a part of the heating device 130 is adjacent to the pumping device 120. In this case, another part of the heating device 130 can heat other parts. For example, another part of the heating device 130 can heat a position in the docking water chamber 111 that is far away from the pumping device 120.

[0053] In the related art, ice forms on the water pump in the water receiving tray and around the water pump, which affects the pumping function of the water pump and easily causes damage to the water pump.

[0054] The present application provides a pumping device 120 in the water receiving chamber 111 to discharge the water in the water receiving chamber 111, and provides a heating device 130 in the water receiving chamber 111, which helps to prevent the water in the water receiving chamber 111 from freezing. At the same time, at least a portion of the heating device 130 is provided adjacent to the pumping device 120, which helps to prevent freezing in and around the pumping device 120. When ice has already formed in the water receiving chamber 111 or the pumping device 120, the heating device 130 can melt the ice, which helps to prevent damage to the pumping device 120 and helps to ensure the pumping function of the pumping device 120, so that the pumping device 120 can discharge water from the water receiving chamber 111, thereby preventing water from accumulating in the water receiving chamber 111.

[0055] For example, the heating device 130 may be configured as a thermal resistance wire or a refrigerant pipe in a refrigerant system of an air conditioner, but is not limited thereto.

[0056] Combination Figure 1 and Figure 4 In some embodiments of the present invention, the heating device 130 is disposed around the pumping device 120 .

[0057] Specifically, at least a portion of the heating device 130 is arranged around the outer periphery of the pumping device 120 so as to increase the heating area and heating range of the pumping device 120 by the heating device 130, thereby improving the heating effect of the heating device 130 on the pumping device 120, and further improving the de-icing effect of the heating device 130 on the inside and around the pumping device 120, which is beneficial to reduce the risk of ice formation inside and around the pumping device 120, and facilitates the pumping device 120 to pump out the water in the water receiving chamber 111.

[0058] Reference Figure 4 In some embodiments of the present invention, the heating device 130 surrounds the pumping device 120 by at least 180°.

[0059] Specifically, the heating device 130 can be arranged around the pumping device 120 for at least half a circle along the circumferential direction of the pumping device 120, which is beneficial to improve the heating effect of the heating device 130 on the periphery of the pumping device 120 and the inside of the pumping device 120. For example, the heating device 130 can be arranged around the pumping device 120 for half a circle, one circle or more circles along the circumferential direction of the pumping device 120 to increase the relative area between the heating device 130 and the pumping device 120, thereby increasing the heating area of ​​the pumping device 120 by the heating device 130, thereby improving the ice-melting effect of the heating device 130 on the periphery of the pumping device 120 and the inside of the pumping device 120.

[0060] It is understandable that the specific arrangement of the heating device 130 around the pumping device 120 can be determined according to actual production requirements and heating needs, and is not specifically limited here, as long as the heating device 130 can meet the ice-melting requirements while avoiding interference between the heating device 130 and the pumping device 120.

[0061] Combination Figure 2 and Figure 4 In some embodiments of the present invention, the pumping device 120 includes a pump head 121 and a driving part 122. Relative to the driving part 122, the pump head 121 is disposed adjacent to the bottom wall of the water receiving chamber 111, and a water inlet 123 is formed on one side of the pump head 121 facing the bottom wall of the water receiving chamber 111. For example, the pump head 121 is located at the lower side of the driving part 122, and the water inlet 123 is formed on the lower side of the pump head 121.

[0062] A groove 112 is formed on the bottom wall of the water receiving chamber 111, and at least part of the pump head 121 extends into the groove 112; and / or at least part of the bottom wall of the water receiving chamber 111 is inclined so that the pumping device 120 is located at the lowest position of the bottom wall of the water receiving chamber 111.

[0063] Specifically, the driving unit 122 can work with the pump head 121 and form a negative pressure at the water inlet 123, so that the pumping device 120 can pump the water in the water receiving chamber 111 into the pumping device 120 through the water inlet 123, wherein the water inlet 123 is arranged close to the bottom wall of the water receiving chamber 111. Even if the water level in the water receiving chamber 111 is low, the pumping device 120 can still pump the water in the water receiving chamber 111, and it is beneficial to improve the pumping effect of the pumping device 120 on the water in the water receiving chamber 111.

[0064] Further integration Figure 2 and Figure 3 A groove 112 is formed on the bottom wall of the water receiving chamber 111 , and at least a portion of the pump head 121 extends into the groove 112 .

[0065] For example, the groove 112 is recessed along a side parallel to the axial direction of the pumping device 120 and away from the pumping device 120, so that the water in the water receiving chamber 111 can be gathered in the groove 112, and at least part of the pump head 121 extends into the groove 112, for example: the water inlet 123 extends into the groove 112, or the pump head 121 extends into the groove 112 completely, so that the pumping device 120 can suck the water in the groove 112, even if the amount of water in the water receiving chamber 111 is small, pumping can be achieved, which is beneficial to reduce the amount of residual water in the water receiving chamber 111.

[0066] At least a portion of the bottom wall of the water receiving chamber 111 is inclined so that the pumping device 120 is located at the lowest position of the bottom wall of the water receiving chamber 111 .

[0067] Exemplarily, in the length direction of the water receiving chamber 111, at least a portion of the bottom wall of the water receiving pan 110 extends obliquely downward from the end away from the pumping device 120 toward the direction close to the pumping device 120, so that the water receiving pan 110 forms a lowest point at a position opposite to the pumping device 120 in a direction parallel to the axial direction of the pumping device 120. The water in the water receiving pan 110 can gather toward the lowest point, which is beneficial for the pumping device 120 to pump out the water in the water receiving pan 110 and prevent water from accumulating in the water receiving chamber 111.

[0068] It should be noted that the “length direction of the water receiving chamber 111” can be understood as a direction extending perpendicular to the central axis L of the pumping device 120. For specific directions, please refer to Figure 1 shown.

[0069] Optionally, at least part of the bottom of the water receiving chamber 111 extends obliquely from one end away from the pumping device 120 toward a direction close to the pumping device 120, and the bottom wall of the water receiving tray 110 forms a lowest position at a position where it is relatively arranged with respect to the pumping device 120, and a groove 112 is provided at the lowest position which is recessed along an axial direction parallel to the pumping device 120 and away from the pumping device 120, and the pumping device 120 can pump out the water in the groove 112, wherein the bottom wall of the water receiving tray 110 can divert the water into the groove 112, which is beneficial to improving the effect of pumping out the water in the water receiving tray 110 and reducing the risk of water accumulation in the water receiving chamber 111.

[0070] Combination Figure 2 and Figure 3 In some embodiments of the utility model, one or more filter elements 114 are provided on the bottom wall of the water receiving tray 110. The filter element 114 can filter water to reduce impurities in the water, which is beneficial to improving the water quality when the water is recycled and reused. The water filtered by the filter element 114 flows to the pumping device 120.

[0071] The filter element 114 may be positioned at a specific location according to actual needs. Figure 2 As shown, one or more filter elements 114 are disposed in the recess 112 , and water is filtered by the filter elements 114 before flowing to the pumping device 120 .

[0072] like Figure 2 As shown, in some embodiments of the present invention, the pump head 121 includes a pump casing 1211 and an impeller 1212, the impeller 1212 is disposed in the pump casing 1211, the water inlet 123 is formed on the pump casing 1211, and the driving part 122 is connected to the impeller 1212 to drive the impeller 1212 to rotate.

[0073] Specifically, the output shaft of the driving unit 122 is connected to the impeller 1212, and the driving unit 122 can drive the impeller 1212 to rotate in the pump casing 1211 to form a negative pressure in the pump casing 1211. The water inlet 123 is formed on the side of the pump casing 1211 that is opposite to the bottom wall of the water receiving tray 110. After the negative pressure is formed in the pump casing 1211, the water in the water receiving chamber 111 can be sucked into the pump casing 1211 through the water inlet 123, and the pumping device 120 can pump the water out of the water receiving tray 110.

[0074] The driving unit 122 may be configured as a motor.

[0075] Furthermore, the pump housing 1211 is a metal part, for example, the pump housing 1211 can be formed as an aluminum alloy part to improve the thermal conductivity of the pump housing 1211, improve the heat transfer effect of the pump housing 1211 to the heating device 130, and further reduce the risk of ice formation in the pumping device 120.

[0076] In addition, the impeller 1212 is a metal part, for example, the impeller 1212 can be formed as an aluminum alloy part, which is beneficial to further improve the thermal conductivity of the pump head 121, thereby helping to further reduce the risk of ice formation in the pumping device 120.

[0077] Combination Figure 2 and Figure 4 In some embodiments of the present invention, the heating device 130 is wrapped with a wear-resistant part 140 , and the wear-resistant part 140 abuts against the pumping device 120 .

[0078] Specifically, the pumping device 120 generates vibrations during operation, and the wear-resistant part 140 is wrapped around the heating device 130 to prevent the pumping device 120 from wearing the heating device 130, which is beneficial to improving the service life of the heating device 130. In particular, when the heating device 130 is configured as a refrigerant pipe in the refrigerant system of an air conditioner, the wear-resistant part 140 can provide good protection for the refrigerant pipe and improve the reliability of the refrigerant system.

[0079] Furthermore, when the wear-resistant part 140 abuts against the pumping device 120, the distance between the heating device 130 and the pumping device 120 is substantially equal to the thickness of the wear-resistant part 140, which is beneficial to reducing the distance between the heating device 130 and the pumping device 120, thereby facilitating reducing the heat loss in the process of transferring the heat from the heating device 130 to the pumping device 120, and improving the heating effect of the heating device 130 on the pumping device 120. Exemplarily, when the heating device 130 is arranged around the pumping device 120, the wear-resistant part 140 is arranged to wrap the portion of the heating device 130 surrounding the pumping device 120, so that the distance between the entire portion of the heating device 130 surrounding the pumping device 120 and the pumping device 120 is relatively small.

[0080] For example, the wear-resistant member 140 may only wrap the side of the heating device 130 facing the pumping device 120, or may completely wrap the portion of the heating device 130 adjacent to the pumping device 120. Figure 2 In the example, the heating device 130 is a refrigerant pipe, and the cross section of the wear-resistant part 140 is formed in an open ring shape.

[0081] In some embodiments of the present invention, the wear-resistant part 140 is a rubber part.

[0082] Specifically, the rubber part has good heat resistance, which is helpful in preventing expansion and deformation caused by the high temperature of the heating device 130, and the rubber part has good wear resistance, which can effectively reduce friction and wear. At the same time, the rubber part can also play a role in vibration reduction and energy absorption. By making the wear-resistant part 140 stop against the pumping device 120, the wear-resistant part 140 can absorb the vibration generated when the pumping device 120 is working, and at the same time can reduce the noise generated by the vibration.

[0083] like Figure 1 As shown, in some embodiments of the present invention, the water receiving tray assembly 100 also includes: at least one fixing member 150, at least a portion of the fixing member 150 is arranged on the side of the bottom wall of the heating device 130 away from the water receiving chamber 111, and the fixing member 150 is limitedly matched with the heating device 130, and the fixing member 150 is snap-connected to the water receiving tray 110.

[0084] Specifically, the side of the heating device 130 that is away from the bottom wall of the water receiving chamber 111 is the upper side of the heating device 130. The fixing member 150 can be limitedly matched with the heating device 130 on the upper side of the heating device 130 to facilitate the assembly of the fixing member 150 and the heating device 130, thereby improving the assembly convenience of the heating device 130, and the fixing member 150 is snap-connected with the water receiving tray 110, so as to fix the heating device 130 on the water receiving tray 110 to prevent the heating device 130 from moving, thereby effectively improving the assembly stability of the heating device 130. By setting the fixing member 150, there is no need to additionally set a connecting member on the heating device 130, so as to facilitate the processing and production of the heating device 130 and facilitate the positioning and installation of the heating device 130.

[0085] It can be understood that the number of fixing parts 150 can be determined according to the structural shape and length size of the heating device 130. For example, when the heating device 130 is relatively long, multiple fixing parts 150 can be set, and the multiple fixing parts 150 are arranged at intervals to improve the assembly stability of the heating device 130; when the heating device 130 is relatively short, one fixing part 150 can be set to fix the heating device 130, thereby ensuring the assembly stability of the heating device 130 and reducing the production cost of the water receiving tray 110. The number of fixing parts 150 is not specifically limited here.

[0086] Combination Figure 1 , Figure 3 and Figure 5 In some embodiments of the utility model, the fixing member 150 includes a first fixing portion 151 and a second fixing portion 152 connected to each other, the first fixing portion 151 defines an installation groove 1511, the notch of the installation groove 1511 is arranged toward the bottom wall of the water receiving chamber 111, the heating device 130 is matched with the installation groove 1511, a clamping hole 1521 is formed on the second fixing portion 152, and a clamping hook 113 is formed on the water receiving tray 110, the clamping hook 113 extends into the clamping hole 1521 and is hooked on the side of the second fixing portion 152 facing away from the bottom wall of the water receiving chamber 111.

[0087] For example, the notch of the mounting groove 1511 is open to the bottom wall of the water receiving chamber 111, and the heating device 130 can be embedded in the mounting groove 1511 through the notch, so that the heating device 130 can be restricted between the bottom wall of the water receiving chamber 111 and the first fixing portion 151; the second fixing portion 152 is formed with a clamping hole 1521 that is arranged through the axial direction parallel to the pumping device 120, and the bottom wall of the water receiving tray 110 is formed with a hook 113 that extends away from the bottom wall, and the hook 113 can extend into the clamping hole 1521 and hook and cooperate with the side of the second fixing portion 152 that is away from the bottom wall of the water receiving chamber 111, so that the fixing member 150 can fix the heating device 130 on the bottom wall of the water receiving tray 110, thereby improving the assembly reliability of the heating device 130; of course, the cooperation between the hook 113 and the clamping hole 1521 can also realize the detachable cooperation between the fixing member 150 and the water receiving tray 110.

[0088] Combination Figure 1 and Figure 5 In some embodiments of the utility model, the hook 113 is suitable for abutting against the hole wall of the hole 1521. There are multiple hooks 113 cooperating with the fixing member 150 and including a first hook 1131 and a second hook 1132. The first hook 1131 and the second hook 1132 are respectively hooked on the side edges of the corresponding two holes 1521 that are opposite to or back to each other.

[0089] Specifically, the hook 113 is engaged with the hole wall of the hole 1521, so that the hook 113 can limit the movement of the fixing member 150, which is beneficial to improve the fixing effect of the fixing member 150 on the heating device 130. A plurality of holes 1521 are formed on the fixing member 150, and the plurality of holes 1521 are arranged at intervals on both sides of the second fixing portion 152. Accordingly, the first hook 1131 and the second hook 1132 can be respectively hooked in the corresponding holes 1521.

[0090] Exemplarily, the second fixing portion 152 may be formed with two clamping holes 1521 on both sides in the length direction of the water receiving tray 110, the first clamping hook 1131 and the second clamping hook 1132 are respectively penetrated through the corresponding clamping holes 1521, and the first clamping hook 1131 and the second clamping hook 1132 may be hooked on the side edges of the corresponding two clamping holes 1521 opposite to each other in the length direction, wherein the length of the clamping hole 1521 may be adapted to the size of the first clamping hook 1131 and the second clamping hook 1132 in the direction parallel to the length of the clamping hole 1521, and the first clamping hook 1131 and the second clamping hook 1132 may be elastic, and when the fixing member 15 During the process of snap-fitting with the first hook 1131 and the second hook 1132, the hole wall of the locking hole 1521 can press against the first hook 1131 and the second hook 1132 to deform them. After at least part of the first hook 1131 and the second hook 1132 extend out of the locking hole 1521, the first hook 1131 and the second hook 1132 recover their deformation and are hooked on the side edges of the two corresponding locking holes 1521 opposite to each other in the length direction. Therefore, while facilitating the first hook 1131 and the second hook 1132 to fit with the fixing member 150, the reliability of the fit can be ensured, and the fixing member 150 can be prevented from moving in the length direction.

[0091] The first hook 1131 and the second hook 1132 can be hooked on the side edges of the corresponding two holes 1521 opposite to each other in the length direction of the water receiving tray 110, wherein the length of the hole 1521 can be slightly larger than the size of the first hook 1131 and the second hook 1132 in the direction parallel to the length of the hook 113, so that the first hook 1131 and the second hook can cooperate with the fixing member 150. When the first hook 1131 and the second hook 1132 are engaged with the fixing member 150, the first hook 1131 and the second hook 1132 can respectively stop against the side hole walls of the corresponding two holes 1521 opposite to each other, thereby preventing the fixing member 150 from moving along the length direction and improving the fixing effect of the fixing member 150 on the heating device 130.

[0092] Combination Figure 1 and Figure 5 In some embodiments of the present invention, a water leakage port 1522 is formed on the second fixing portion 152 .

[0093] Exemplarily, the water leakage port 1522 can be formed between multiple card holes 1521, and the water leakage port 1522 can be set through the second fixed part 152 in an axial direction parallel to the pumping device 120. When water falls on the second fixed part 152, the water can flow into the water receiving chamber 111 through the water leakage port 1522, which is beneficial to avoid water accumulation on the second fixed part 152.

[0094] In some embodiments of the present invention, the water tray assembly 100 is used in an air conditioner, which has a refrigerant circulation system, and the refrigerant circulation system includes a condenser and a throttling device, such as Figure 1 As shown, the heating device 130 includes a connecting pipe 131, which is suitable for connecting between the condenser and the throttling device. At least part of the refrigerant flowing out of the condenser flows into the connecting pipe 131 and heats the ice in the water receiving chamber 111 to melt the ice. The refrigerant after heat exchange flows to the throttling device.

[0095] It can be understood that the air conditioner can be an integrated air conditioner or a split air conditioner. For example, the air conditioner can be a wall-mounted air conditioner, a floor-standing air conditioner or a window air conditioner. The connecting pipe 131 is suitable for connecting between the condenser and the throttling device. The connecting pipe 131 can be connected in series between the condenser and the throttling device, or in parallel with the pipeline between the condenser and the throttling device; for example: when the connecting pipe 131 is connected in parallel with the pipeline between the condenser and the throttling device, a switch valve can be provided on the connecting pipe 131 to achieve conduction and isolation of the connecting pipe 131, so as to control the flow of refrigerant to the connecting pipe 131. For example, when the water in the water receiving chamber 111 is frozen, the switch valve is opened to melt the ice. When the water in the water receiving chamber 111 is not frozen, the switch valve can be closed.

[0096] For example: when the heat exchanger is used as an outdoor heat exchanger, the indoor heat exchanger is a condenser, and the connecting pipe 131 is connected between the indoor heat exchanger and the throttling device; when the heat exchanger is used as an indoor heat exchanger, the outdoor heat exchanger is a condenser, and the connecting pipe 131 is connected between the outdoor heat exchanger and the throttling device.

[0097] Combination Figure 1 and Figure 4 In some embodiments of the utility model, the connecting pipe 131 includes a first pipe section 1311 and a second pipe section 1312. The first pipe section 1311 is arranged around the pumping device 120 and is suitable for connecting to the condenser. The second pipe section 1312 extends along the extension direction of the water receiving chamber 111 and is suitable for connecting to the throttling device.

[0098] Specifically, the refrigerant discharged from the condenser flows through the first pipe section 1311 and the second pipe section 1312 in sequence and then flows into the throttling device, wherein the refrigerant preferentially flows through the first pipe section 1311. At this time, the temperature of the refrigerant is relatively high, which is beneficial to improving the heating effect of the refrigerant on the pumping device 120, further reducing the risk of freezing in the pumping device 120 or improving the effect of the refrigerant on melting ice in the pumping device 120. The refrigerant after heat exchange with the pumping device 120 flows into the second pipe section 1312 and heats other positions of the docking water chamber 111 to prevent the water in the water receiving chamber 111 from freezing or to melt the ice in the docking water chamber 111.

[0099] Combination Figure 1 and Figure 4In some embodiments of the present invention, the pumping device 120 is disposed at one end of the water receiving chamber 111 in its extension direction, and the ends of the first pipe section 1311 and the second pipe section 1312 that are away from each other are both located at the end where the pumping device 120 is located.

[0100] Specifically, the connection end between the first pipe section 1311 and the condenser and the connection end between the second pipe section 1312 and the throttling device and the pumping device 120 are all located on the same side of the water receiving chamber 111, so that the structure inside the water receiving chamber 111 is compact and convenient for installation and maintenance of the water tray assembly 100.

[0101] Combination Figure 1 and Figure 3 In some embodiments of the present invention, the water receiving tray 110 is further formed with a float cavity 115 , which is communicated with the water receiving cavity 111 , and the float cavity 115 is used to arrange a float 116 to detect the water level in the water receiving tray 110 .

[0102] Exemplarily, the float chamber 115 can be arranged adjacent to the groove 112 so that the float 116 can detect the water level around the pumping device 120, and the float 116 can feed back the detected water level signal to the controller, and the controller can adjust the working state of the pumping device 120 according to the water level, etc., which is beneficial to prevent water in the water receiving tray 110 from overflowing.

[0103] The air conditioner according to the embodiment of the utility model includes the water receiving tray assembly 100 mentioned above.

[0104] Since the air conditioner is provided with the above-mentioned water receiving tray assembly 100, by arranging a pumping device 120 in the water receiving chamber 111 to discharge the water in the water receiving chamber 111, and by arranging a heating device 130 in the water receiving chamber 111, it is helpful to prevent the water in the water receiving chamber 111 from freezing. At the same time, at least a part of the heating device 130 is arranged adjacent to the pumping device 120, which is helpful to prevent freezing in and around the pumping device 120. When ice has formed in the water receiving chamber 111 or the pumping device 120, the heating device 130 can melt the ice, which is helpful to prevent damage to the pumping device 120 and to ensure the pumping function of the pumping device 120, so that the pumping device 120 can discharge water from the water receiving chamber 111, thereby preventing water from accumulating in the water receiving chamber 111.

[0105] In some embodiments of the present invention, the air conditioner is a window air conditioner.

[0106] Specifically, the window air conditioner includes an indoor unit part and an outdoor unit part. The outdoor unit part is arranged on the outdoor side of the wall, and the indoor unit part is arranged on the indoor side of the wall. The outdoor unit part includes an outdoor heat exchanger, a compressor and a four-way valve, and the indoor unit part includes an indoor heat exchanger. The inlet and outlet of the compressor are respectively connected to two valve ports of the four-way valve, and the other two valve ports of the four-way valve are respectively connected to the outdoor heat exchanger and the indoor heat exchanger; further, the window air conditioner also includes a connecting part, which is used to connect the indoor unit part and the outdoor unit part. The outdoor unit part and the connecting part are rotatably connected around a pivot axis. After the installation is completed, the window air conditioner is generally in the shape of a saddle, and is straddled on the wall, which can improve the installation convenience of the air conditioner.
