Description

Technical Field

[0001] The invention relates to the technical field of air conditioners, and in particular provides a water receiving tray assembly and a mobile air conditioner. Background Art

[0002] At present, both wall-mounted air conditioners and floor-standing air conditioners need to be fixedly installed in a limited position and cannot be moved. Therefore, mobile air conditioners have emerged. Mobile air conditioners mainly include a housing, an indoor air flow circulation component and an outdoor air flow circulation component, wherein the indoor air flow circulation component and the outdoor air flow circulation component are both arranged in the housing, and the housing is provided with indoor air inlets and indoor air outlets corresponding to the indoor air flow circulation component, and the housing is also provided with outdoor air inlets and outdoor air outlets corresponding to the outdoor air flow circulation component. Since the mobile air conditioner is very small in size, it can be moved to different locations or rooms to adjust the temperature of the air in the location or room.

[0003] In the related art, a mobile air conditioner is usually provided with a water receiving pan, which divides the cavity in the housing of the mobile air conditioner into an indoor heat exchange chamber and an outdoor heat exchange chamber distributed vertically, wherein an evaporator is arranged in the indoor heat exchange chamber, and a condenser is arranged in the outdoor heat exchange chamber. When the mobile air conditioner is in operation, especially in the cooling mode, the evaporator will produce a large amount of condensed water. If the condensed water cannot be drained out in time and quickly, it will affect the performance of the mobile air conditioner and reduce the working efficiency. Summary of the invention

[0004] The present invention aims to solve the above technical problem, that is, to solve the problem of condensed water accumulation in the evaporator of the mobile air conditioner.

[0005] In a first aspect, the present invention provides a water receiving pan assembly, comprising: a water receiving pan body, which is constructed with water retaining ribs, a water receiving trough is defined between the water retaining ribs and the peripheral side walls of the water receiving pan body, the water receiving trough is configured to receive condensed water from an indoor heat exchanger, the water receiving trough has a first trough section and a second trough section that are bent and connected; a drainage trough is formed by a downward depression of a trough bottom wall portion of the first trough section, and condensed water in the water receiving trough flows toward the drainage trough from the second trough section toward the first trough section; a first guide rib is arranged on the water retaining rib or the peripheral side wall of the water receiving pan body, and is used to support the indoor heat exchanger, the first guide rib is inclined toward the peripheral side wall of the water receiving pan body or the water retaining rib along the flow direction of condensed water; a drainage hole is arranged on the peripheral side wall of the water receiving pan body and is connected to the drainage trough, and the drainage hole is configured to be connected to a drainage pipe or a cover.

[0006] When the above technical solution is adopted, the shape of the water receiving trough matches the indoor heat exchanger, and the first guide rib is provided to support the indoor heat exchanger so as to form a flow space for condensed water between the indoor heat exchanger and the bottom wall of the water receiving pan body; at the same time, the first guide rib is provided to be inclined along the flow direction of the condensed water toward the peripheral side wall of the water receiving pan body or the water retaining rib, that is, the first guide rib can guide the condensed water in the receiving trough, so that the condensed water flows quickly toward the direction of the drainage trough, so that it can be quickly discharged through the drainage hole to avoid the accumulation of condensed water.

[0007] In an optional implementation scheme of the above-mentioned water receiving tray assembly, it also includes: a first overflow hole, which is arranged on the rear groove wall of the drainage groove, and the rear groove wall is arranged opposite to the drainage hole; a water receiving box, which is arranged below the first overflow hole and is configured to receive overflowed condensed water.

[0008] When the drain hole is closed, or when there is too much condensed water in the water tank, the condensed water flows into the water box through the overflow port, thereby collecting the condensed water and preventing the condensed water from overflowing and flowing along the inner wall of the housing of the mobile air conditioner to other components. While increasing the discharge methods of the condensed water, the safety of the mobile air conditioner can be improved. In addition, the coldness of the collected condensed water can also be used to cool the outdoor heat exchanger of the mobile air conditioner, thereby improving the heat exchange capacity of the outdoor heat exchanger and improving energy utilization.

[0009] In an optional implementation scheme of the water receiving tray assembly, the present invention further comprises: a drainage pipe, which is arranged on the rear groove wall and extends toward the water receiving box, and the drainage pipe is connected with the drainage groove through the first overflow channel.

[0010] By setting up the drainage pipe, the flow direction of the condensate water overflowing from the drainage trough can be limited and guided, reducing or even avoiding the splashing of the condensate water.

[0011] In an optional implementation scheme of the above-mentioned water tray assembly, the drainage groove includes: a receiving bottom wall extending along a first direction; two connecting side walls, both extending along the first direction, respectively arranged on two opposite sides of the receiving bottom wall and connected to the groove bottom wall of the first groove section, wherein the distance between the two connecting side walls gradually decreases from top to bottom; the first direction is the direction of the rear groove wall toward the drainage hole.

[0012] With such arrangement, the condensate flowing toward the receiving bottom wall can be guided by the inclined connecting side wall, and water accumulation at the edge where the connecting side wall and the bottom wall of the first groove section are connected can be avoided, thereby improving the flow efficiency of the condensate.

[0013] In an optional embodiment of the above-mentioned water receiving tray assembly, the receiving bottom wall is constructed as an arc-shaped bottom wall and matches the shape of the drainage hole.

[0014] By setting the receiving bottom wall to be an arc shape and matching the shape of the drainage hole, it is possible to avoid the accumulation of condensation water in the drainage groove while ensuring the matching degree between the drainage groove and the drainage hole, improving the flow efficiency, avoiding the accumulation of condensation water around the drainage hole, and reducing the accumulation of dirt and the growth of bacteria.

[0015] In an optional implementation scheme of the above-mentioned water receiving tray assembly, it also includes: a drainage nozzle, which is arranged on the peripheral side wall of the water receiving tray body, matches the shape of the drainage hole and is integrally connected to the receiving bottom wall.

[0016] The provision of the drain nozzle makes it easier to connect to the drain pipe or to install the cover.

[0017] In an optional implementation scheme of the water receiving tray assembly, the present invention further comprises: a guide plate, which is arranged on the outer wall surface of the receiving bottom wall, is located above the water receiving box, and extends toward the water receiving box.

[0018] By setting the guide plate, the condensed water spreading out from the drainage nozzle can be guided. This part of the condensed water flows along the outer wall surface of the receiving bottom wall to the guide plate, and under the action of the guide plate, flows to the water receiving box.

[0019] In an optional implementation of the water receiving tray assembly, a first side surface of the guide plate facing the drainage hole and an outer wall surface of the receiving bottom wall have an arc transition.

[0020] By providing an arc transition between the first side surface of the guide plate facing the drain nozzle and the outer wall surface of the receiving bottom wall, the flow efficiency of the condensate water toward the guide plate can be improved, while the stress concentration between the guide plate and the receiving bottom wall can be reduced, thereby improving the structural stability.

[0021] In an optional implementation scheme of the water receiving tray assembly, an angle reinforcement rib is provided between the second side surface of the guide plate and the outer wall surface of the receiving bottom wall; wherein the second side surface is arranged opposite to the first side surface.

[0022] By providing the corner reinforcement ribs, the structural stability of the guide plate can be further improved.

[0023] In an optional implementation scheme of the above-mentioned water receiving pan assembly, it also includes: support ribs, which are arranged on the water receiving trough and bend and extend in the direction from the second trough section to the first trough section, and the support ribs divide the water receiving trough into a first water receiving space and a second water receiving space; second guide ribs, which are arranged on the support ribs and have the same extension direction as the first guide ribs, and the second guide ribs and the first guide ribs are respectively located in the second water receiving space and the first water receiving space; wherein the first guide ribs, the support ribs and the second guide ribs jointly support the indoor heat exchanger.

[0024] By setting the supporting ribs, the bearing capacity of the indoor heat exchanger can be improved, and the condensate can be diverted at the same time. The first water receiving space and the second water receiving space respectively receive the condensate generated by different parts of the indoor heat exchanger. By cooperating with the first guide rib and the second guide rib, the diversion effect of the condensate can be further improved.

[0025] In an optional implementation scheme of the above-mentioned water receiving tray assembly, the supporting ribs extend above the drainage groove and are fixedly connected to the side walls of the drainage groove, and the first water receiving space and the second water receiving space are both connected to the drainage groove.

[0026] Such an arrangement can improve the structural strength of the supporting ribs and ensure the supporting effect for the indoor heat exchanger.

[0027] In an optional implementation scheme of the above-mentioned water receiving tray assembly, it also includes: a second overflow hole, which is arranged on the bottom wall of the water receiving tray body, is located outside the water receiving trough and is close to the first trough section; an overflow pipe, which is arranged in the second overflow hole and extends toward the water receiving box.

[0028] When the drainage capacity of the first overflow hole and the drainage hole is insufficient, the second overflow hole can be set to divert the condensate overflowing from the self-supporting ribs so that the condensate flows into the water receiving box and is collected; the overflow pipe can be set to divert the condensate to avoid splashing.

[0029] In an optional implementation scheme of the water receiving tray assembly, the diameter of the overflow pipe gradually decreases along the direction toward the water receiving box.

[0030] By arranging the diameter of the overflow pipe to gradually decrease in the direction toward the water receiving box, the impact force and vibration of the condensed water can be limited and the noise can be reduced.

[0031] In a second aspect, the present invention provides a mobile air conditioner, comprising the water receiving pan assembly as described above; and an indoor heat exchanger installed in the water receiving tank.

The third guide rib is parallel to the first guide rib 310.

[0063] Optionally, a drainage hole 140 is provided on the peripheral side wall 112 of the water receiving tray body 100. The drainage hole 140 is arranged corresponding to the drainage groove 200 and is connected to the drainage groove 200. The drainage hole 140 is used to connect a drainage pipe to discharge condensed water, or to connect a cover.

[0064] Optionally, the lowest point of the drain hole 140 is flush with the lowest point of the drain groove 200, or the lowest point of the drain hole 140 is lower than the lowest point of the drain groove 200. In this way, the condensed water is facilitated to flow to the drain hole 140.

[0065] Optionally, the bottom walls of the first groove section 131 around the drainage groove 200 are concavely inclined toward each other to facilitate the flow of condensed water into the drainage groove 200 .

[0068] When the drain hole 140 is closed, or when there is too much condensed water in the water receiving tank 130, the condensed water flows into the water receiving box 400 through the overflow port, thereby collecting the condensed water and preventing the condensed water from overflowing and flowing along the inner wall of the outer shell of the mobile air conditioner to other components. This increases the discharge methods of the condensed water and improves the safety of the mobile air conditioner.

[0069] In addition, the coldness of the collected condensed water can also be used to cool the outdoor heat exchanger of the mobile air conditioner, thereby improving the heat exchange capacity of the outdoor heat exchanger 40 and improving the energy utilization rate.

[0070] Optionally, the drain groove 200 has a rear groove wall 210, and the rear groove wall 210 is arranged opposite to the drain hole 140. In this way, a drain space corresponding to the drain hole 140 can be formed below the water receiving tray body 100.

[0076] Optionally, the drainage pipe 212 is configured as a circular pipe, a semicircular pipe or a pipe of other shapes. The drainage groove 200 has a rear groove wall 210 that constitutes a part of the drainage pipe 212. In this way, the drainage pipe 212 can be connected to the drainage groove 200.

The distance between the two connecting side walls 230 gradually decreases from top to bottom. The first direction is the direction from the rear trough wall 210 toward the drain hole 140.

[0082] The distance between the two connecting side walls 230 gradually decreases from top to bottom, that is, the connecting side walls 230 are inclined. In this way, the condensed water flowing toward the receiving bottom wall 220 can be guided by the inclined connecting side walls 230, avoiding water accumulation at the edge where the connecting side walls 230 are connected to the bottom wall of the first trough section 131, thereby improving the flow efficiency of the condensed water.

[0093] After the drain pipe or the cover is connected, if there is a lot of condensed water, some condensed water may spread out from the connection between the connection pipe / cover and the drain nozzle 141, and the spread condensed water will flow along the outer wall surface of the receiving bottom wall 220. The condensed water spread out from the drain nozzle 141 can be diverted by the setting of the guide plate 160, and this part of the spread condensed water flows along the outer wall surface of the receiving bottom wall 220 to the guide plate 160, and under the action of the guide plate 160, flows to the water receiving box 400.

[0094] Optionally, the guide plate 160 extends into the interior of the water receiving box 400 to reduce the noise of condensed water dripping.

[0103] Alternatively, the corner reinforcement rib 161 is not provided.

[0104] In the optional implementation of the water receiving tray assembly, a support rib 150 and a second guide rib 320 are further included. The support rib 150 is arranged on the water receiving trough 130, and is bent and extended in the direction from the second trough section 132 to the first trough section 131. The support rib 150 divides the water receiving trough 130 into a first water receiving space and a second water receiving space. The second guide rib 320 is arranged on the support rib 150, and has the same extension direction as the first guide rib 310.

Among them, the first guide rib 310, the support rib 150 and the second guide rib 320 jointly support the indoor heat exchanger 30.

[0105] Optionally, upper end surfaces of the first guide rib 310 , the support rib 150 , and the second guide rib 320 are flush so as to stably support the indoor heat exchanger 30 together.

[0106] By setting the support ribs 150, the bearing capacity of the indoor heat exchanger 30 can be improved, and the condensed water can be diverted, and the first water receiving space and the second water receiving space respectively receive the condensed water generated by different parts of the indoor heat exchanger 30. At the same time, the first guide rib 310 and the second guide rib 320 are arranged in parallel, so that the flow direction of the condensed water is consistent, and the cooperation with the first guide rib 310 and the second guide rib 320 can further improve the guiding effect of the condensed water.

[0107] Optionally, the support rib 150 and the second guide rib 320 are not provided.

[0108] Alternatively, the first guide rib 310 is disposed on the water retaining rib 120, and the second guide rib 320 is disposed on the peripheral side wall 112.

[0110] In an optional implementation scheme of the above-mentioned water receiving tray assembly, the support rib 150 extends above the drain trough 200 and is fixedly connected to the side wall of the drain trough 200 , and the first water receiving space and the second water receiving space are both connected to the drain trough 200 .

[0111] Such an arrangement can improve the structural strength of the support ribs 150 and ensure the supporting effect for the indoor heat exchanger 30 .

[0112] Alternatively, a notch is provided above the supporting rib 150 corresponding to the drainage groove 200 .

[0113] In the optional embodiment of the water receiving tray assembly, a second overflow hole 171 and an overflow pipe 172 are further included. The second overflow hole 171 is disposed on the bottom wall of the water receiving tray body 100, outside the water receiving groove 130, and close to the first groove section 131. The overflow pipe 172 is disposed in the second overflow hole 171 and extends toward the water receiving box 400.

[0114] When the drainage capacity of the first overflow hole 211 and the drainage hole 140 is insufficient, the second overflow hole 171 can be provided to guide the condensed water overflowing from the supporting rib 150 so that the condensed water flows into the water receiving box 400 for collection. The overflow pipe 172 can be provided to guide the condensed water to avoid splashing of the condensed water.

[0115] Optionally, the second overflow hole 171 is opened on the bottom plate 111, and the hole diameter is consistent from top to bottom. Alternatively, the hole diameter of the second overflow hole 171 gradually decreases from top to bottom. Or, the hole diameter of the second overflow hole 171 gradually increases from top to bottom. From top to bottom here refers to the direction from the bottom plate 111 toward the surface of the indoor heat exchanger 30, toward the water receiving box 400.

[0116] Optionally, a plurality of second overflow holes 171 are provided, and correspondingly, a plurality of overflow pipes 172 are provided.

[0117] Optionally, the overflow pipe 172 extends into the water receiving box 400 to reduce the flow noise of the condensed water.

[0119] In an optional embodiment of the above-mentioned water receiving tray assembly, the diameter of the overflow pipe 172 gradually decreases along the direction toward the water receiving box 400.

[0120] By arranging the diameter of the overflow pipe 172 to gradually decrease in the direction toward the water receiving box 400, the impact force and vibration of the condensed water can be limited and the noise can be reduced.

[0121] Alternatively, the diameter of the overflow pipe 172 gradually increases along the direction toward the water receiving box 400. Alternatively, the diameter of the overflow pipe 172 remains unchanged along the direction toward the water receiving box 400.

[0122] Second, combining Figures 1 to 10 As shown, the present invention provides a mobile air conditioner, comprising the aforementioned water receiving pan assembly and an indoor heat exchanger 30, wherein the indoor heat exchanger 30 is installed in a water receiving groove 130 formed on the water receiving pan assembly.

[0123] When the above technical solution is adopted, the shape of the water receiving groove 130 matches the indoor heat exchanger 30, and the first guide rib 310 is provided to support the indoor heat exchanger 30, so as to form a flow space for condensed water between the indoor heat exchanger 30 and the bottom wall of the water receiving pan body 100; at the same time, the first guide rib 310 is provided to be inclined along the flow direction of the condensed water toward the peripheral side wall 112 of the water receiving pan body 100 or the water retaining rib 120, that is, the first guide rib 310 can guide the condensed water in the water receiving groove 130, so that the condensed water flows quickly toward the direction of the drainage groove 200, so that it can be quickly discharged through the drainage hole 140 to avoid the accumulation of condensed water.

[0124] Optionally, the mobile air conditioner includes a housing 10, and a cavity is defined inside the housing 10.

The outdoor heat exchanger 40 is disposed in the outdoor cavity 12. The water receiving box 400 is disposed in the outdoor cavity 12, and is located above the outdoor heat exchanger 40. The condensed water in the water receiving box 400 can be sprayed, sprinkled, or dripped onto the surface of the outdoor heat exchanger 40.

[0125] Optionally, the mobile air conditioner further includes an outdoor air duct assembly 20, an indoor fan, an outdoor fan and a motor assembly 50. The upper air duct plate of the outdoor air duct assembly 20 constitutes a water receiving tray body 100, and the water receiving box 400 is arranged on the lower air duct plate of the outdoor air duct assembly 20 and is located outside the air duct of the outdoor air duct assembly.

The first output shaft 51 of the motor assembly 50 extends into the indoor cavity 11 and is connected to the indoor fan drive, and the second output shaft 52 is connected to the outdoor fan drive. In this way, the components can be reduced and the volume of the mobile air conditioner can be reduced.

[0126] In addition, by making the upper air duct plate of the outdoor air duct assembly 20 form the water receiving tray body 100, and arranging the water receiving box 400 on the lower air duct plate of the outdoor air duct assembly 20 and outside the air duct of the outdoor air duct assembly, the space utilization rate in the cavity can be improved.

[0127] Optionally, the water receiving box 400 is integrally formed with the lower air duct plate.
