[0033] The present invention provides a water receiving tray 100 and a window type air conditioner 200 using the water receiving tray 100. Figure 1 and Figure 2 In the embodiment of the present invention, the water tray 100 includes a main tray body 110 and a drainage structure connected to the main tray body 110. The drainage structure 130 can be a drainage hole, a drainage pipe, or a drainage groove. The bottom wall of the main tray body 110 is arranged in an inclined surface from a direction away from the drainage structure to a direction close to the drainage structure, and the drainage structure is located at the lowest point of the inclined surface. When the water tray 100 is applied to a window air conditioner, please refer to Figures 3 to 5 In an embodiment of the window air conditioner 200, the window air conditioner 200 has a casing 210, wherein the window air conditioner 200 is divided into an indoor structure 200a and an outdoor structure 200b corresponding to the indoor side and the outdoor side, and the casing 210 has two parts corresponding to the indoor structure 200a and the outdoor structure 200b respectively. Specifically, the casing 210 includes a box body 211 and a chassis 212 arranged at the lower part of the box body 211, and the indoor structure 200a also includes an evaporator 220 and an indoor fan 230 arranged in the box body 211, and an indoor air inlet 231 and an indoor air outlet 232 arranged on the box body 211, and a filter is arranged on the indoor air inlet 231, and the evaporator 220 is located between the indoor air inlet 231 and the indoor fan 230, and the evaporator 220 can be a single-stage type or a multi-stage type, wherein the attached Figure 3The evaporator 220 is divided into two sections, and the indoor air enters through the indoor air inlet 231 and is discharged through the indoor air outlet 232 under the drive of the indoor fan 230. The outdoor structure 200b also includes an outdoor fan, a condenser, a compressor, and an outdoor air inlet and an outdoor air outlet arranged on the box 211.

[0034] The water receiving pan 100 is installed on the bottom plate 212 and is located below the evaporator 220 to receive the condensed water generated during the heat exchange process of the evaporator 220. The bottom wall of the water receiving pan 100 is arranged as an inclined surface, which can be understood as the upper surface of the water receiving pan 100 facing the evaporator 220 is arranged as an inclined surface, and the bottom wall is arranged as shown in the attached Figure 1 and 2 The bottom wall is inclined in the left and right directions, and the left side of the bottom wall is higher than the right side. The inclination angle can be set according to actual needs and is not limited here. The bottom wall is configured as an inclined surface. During the production process of the water receiving tray 110, the thickness of the bottom wall gradually decreases from left to right, especially the upper surface of the bottom wall facing the evaporator 220 gradually tilts downward from left to right. Therefore, during the heat exchange process of the evaporator 220, the condensed water will flow along the surrounding due to its own gravity. Figure 1 , 2 The water is discharged to the outdoor side of the window type air conditioner 200 through the drainage structure 130 provided at the right end of the water receiving tray 100 in the direction of the arrow in 5 .

[0035] The technical solution of the present invention is that a drainage structure is connected to one end of the main plate body 110 of the water receiving tray 100, and the bottom wall of the main plate body 110 is set to form an inclined surface from the end away from the drainage structure 130 to the end close to the drainage structure 130, and the drainage structure 130 is located at the lowest point of the inclined surface. Therefore, the condensed water generated during the cooling process of the air conditioner will be quickly discharged to the outside through the drainage structure 130 along the bottom wall of the water receiving tray 100, and the condensed water is not easy to overflow on the indoor side.

[0036] The main plate body 110 of the present application is also formed with a water guide groove 111 connected to the drainage structure. The water guide groove 111 is connected to the drainage structure, and the groove bottom wall 113 of the water guide groove 111 is an inclined surface from the direction away from the drainage structure to the direction close to the drainage structure. The water guide groove 111 is formed in a position roughly in the middle of the entire main plate body 110. The water guide groove 111 corresponds to the bottom of the evaporator 220. The condensed water generated by the evaporator 220 can be gathered in the water guide groove 111 and quickly discharged by the drainage structure. The drainage structure of the present application is preferably a drainage groove 130. The condensed water in the heat exchange process of the evaporator 220 is gathered in the water guide groove 111 and can quickly flow along the groove bottom wall 113 and be discharged by the drainage groove 130.

[0037] In order to facilitate the discharge of condensed water to the outdoor side of the window air conditioner 200, the present application extends the drainage groove 130 to the outdoor side of the window air conditioner 200, and the present application opens a drainage hole 2121 on the chassis 212 of the window air conditioner 200 (see attached Figure 5 ), after the drainage groove 130 extends to the outdoor side of the chassis 212, the water is discharged to the outside through the drainage hole 2121. The above-mentioned arrangement of the drainage groove 130 reduces the number of pipes required for the window air conditioner 200, and the structure is optimized and concise.

[0038] The water receiving tray 100 of the present application also includes a buffer groove 150, which is connected to the other end of the main plate 110 away from the drainage groove 130, and the two ends of the water guide groove 111 are connected to the buffer groove 150 and the drainage groove 130 respectively. Since the evaporator 220 has side plates and more pipe structures at the ends on both sides, more condensed water will be generated on the left and right sides during the heat exchange process of the evaporator 220. By adding a buffer groove 150 on the water receiving tray 100, the buffer groove 150 corresponds to the end of the evaporator 220. Therefore, when a large amount of condensed water is generated at the end of the evaporator 220 during the operation of the window air conditioner, due to the buffering effect of the buffer groove 150, the condensed water with a low temperature just generated will not immediately fall onto the bottom plate 212 of the window air conditioner 200, but will overflow from the buffer groove 150 after being heated in the buffer groove 150. Therefore, the phenomenon that the indoor part of the window air conditioner 200 also generates condensed water due to the low temperature of the condensed water is greatly improved.

[0039] The bottom wall of the buffer groove 150 of the present application is lower than the bottom wall 113 of the water guide groove 111. Figure 2 It can be seen that the end of the main plate body 110 corresponding to the buffer groove 150 is also constructed in a step shape, so that when there is a lot of condensed water generated at this place of the evaporator 200, a small part of the condensed water will flow into the buffer groove 150 along the multiple steps, and most of the condensed water will be discharged from the drainage groove 130 along the water guide groove 111. By setting the bottom wall of the buffer groove 150 lower than the bottom wall of the main plate body 110, the condensed water with a lower temperature flows to the bottom of the buffer groove 150, and the condensed water in the upper layer of the buffer groove 150 with a higher temperature will overflow to the bottom plate 212.

[0040] The buffer slot 150 of the present application is connected to one side of the main disk body 110 facing the outdoor side of the window air conditioner 200, and extends from the indoor side to the outdoor side of the window air conditioner 200. The buffer slot 150 extends from the indoor side to the outdoor side of the window air conditioner 500, which utilizes the narrow and long space from the indoor side to the outdoor side in the window air conditioner 200, thereby not increasing the volume of the window air conditioner 200.

[0041] The above content introduces the improvement of the water receiving pan 100 proposed in the present application in receiving and discharging condensed water. On the one hand, the condensed water can be quickly discharged from the window air conditioner 200. On the other hand, the buffer groove 150 can prevent the condensed water with lower temperature from dripping directly onto the bottom plate 212, so that it is not easy to generate condensed water on the outer surface of the indoor side of the window air conditioner 200. It can be understood that the water receiving pan 100 of the present application is applicable to air conditioners of other structural forms besides the window air conditioner 200, such as mobile air conditioners, integrated air conditioners, etc.

[0042] In some embodiments, the main plate body 110 is further formed with a sealing step 113 that contacts the bottom of the evaporator 220, and one surface of the sealing step 113 is in surface contact with the bottom of the evaporator 220 to achieve sealing. The present application forms a sealing step 113 on the surface of the side wall 120 of the main plate body 110 facing the evaporator 220, and the sealing step 113 contacts the bottom of the evaporator 220 to prevent airflow from passing between the bottom of the evaporator 220 and the water receiving tray 100. Therefore, during the use of the window air conditioner 200, the airflow entering the air conditioner is fully contacted with the evaporator 220 before being discharged, which can greatly improve the heat exchange efficiency of the window air conditioner 200. In other embodiments, the sealing step 113 can also be a groove structure that at least partially wraps the bottom of the evaporator 220. Specifically, the groove structure can be correspondingly arranged at the sealing step 113, and can be two spaced-apart baffles protruding upward from the bottom wall, and the baffles and the bottom wall form a groove structure, and the bottom side plate of the evaporator 220 is embedded in the groove structure.

[0043] Furthermore, the window air conditioner 200 further includes an air duct volute 240 covering the air outlet side of the evaporator 220, and the sealing step 113 includes a sealing side wall 115 and a sealing top wall 117, the sealing top wall 117 is in sealing contact with the bottom of the air duct volute 240, and the sealing side wall 115 is in sealing contact with the bottom of the evaporator 220. The sealing top wall 117 and the sealing side wall 115 are both inclined to guide condensed water into the water guide groove 111. In the actual installation process, the lower section of the evaporator 220 is also tilted, and the inclination angle of the sealing side wall 115 is suitable for installing the evaporator 220.

[0044] Furthermore, a mounting portion 170 is connected to the other side wall 112 of the main disk body 110 . The mounting portion 170 is used to abut against the side of the evaporator 220 and support the evaporator 220 .

[0045] The mounting portion 170 is an upwardly protruding bracket structure used to support the evaporator 220, and the mounting portion 170 is also inclined and is respectively provided at both ends of the main disk body 110. During the assembly process, the mounting portion 170 cooperates with the sealing step 113 to position and clamp the two sides of the lower part of the evaporator 220, making the assembly more convenient.

[0046] The mounting portion 170 is also provided with a snap-fitting position 171 that is snap-fitted with the side plate on the evaporator 220. The snap-fitting position 171 is in the shape of a groove. When the side plate of the evaporator 220 is snapped into the snap-fitting position 171 during the assembly process, the bottom of the evaporator 220 contacts the contact surface 115, so that the mounting portion 170 bears a large gravity of the evaporator 220, and the contact surface 115 can reduce the impact of the evaporator 220, so that the sealing step 113 is not easily deformed due to the extrusion of the evaporator 220.

[0047] In some embodiments, the main tray 110 is further provided with an air inlet 190, and the mounting portion 170 is provided with at least two air inlets 190 at intervals, and the air inlet 190 is located between the two mounting portions 170. In the present application, the water tray 100 is also provided with an air inlet 190, and the bottom plate 212 of the window air conditioner 200 is also provided with an air inlet corresponding to the air inlet 190. When the window air conditioner 200 is in use, air can be simultaneously introduced from the front side and the bottom to increase the air intake volume and improve the heat exchange efficiency.

[0048] The window air conditioner 200 of the present application is suitable for being installed in a mounting opening on a wall when in use, and a movable shielding member is provided in the mounting opening; the shielding member can be a window, a window sash, a curtain, or a window blind.

[0049] In order to achieve good sealing and less air leakage during the use of the window air conditioner 200, please refer to Figure 3 , 6 7. The outer peripheral wall of the box body 211 of the window air conditioner 200 of the present application is provided with a downwardly recessed receiving groove 213, and at least a portion of the shielding member can extend into the receiving groove 213 (for example, it extends into the receiving groove 213 during the process of the window closing and moving down), and the chassis 212 is placed on the wall surface of the installation opening of the wall; further, the window air conditioner 200 also includes a sealing device 250, which is movably connected to the casing 210, and the sealing device 250 is movable to switch between a storage state and a working state. In the storage state, the sealing device 250 is stored in the receiving groove 213, and in the working state, the sealing device 250 extends from the receiving groove 213 and contacts with the lower end of the shielding member to seal the gap between the shielding member and the installation opening.

[0050] Specifically, the sealing device 250 can be rotatably connected or detachably connected to the bottom wall of the accommodating groove 213, and is arranged in pairs on opposite sides of the box body 211. When rotatably connected, the end of each sealing device 250 can be rotatably connected to the casing 210 by forming a hook arranged at its end and a rotating shaft arranged in the accommodating groove 213, and when the sealing device 250 is in a sealed state, it has a thickness equal to the distance between the bottom wall of the accommodating groove 213 and the surface of the mounting port where the window air conditioner 200 is placed. Therefore, the sealing device 250 can seal the gap between the bottom of the shielding member and the surface of the mounting port and located on the left and right sides of the window air conditioner 200 after the shielding member moves down to the bottom wall of the accommodating groove 213, thereby reducing the phenomenon of air leakage from the window air conditioner 200 to the installation location to the outside world in the room, thereby improving the cooling and heating effects of the window air conditioner 200.

[0051] The sealing device 250 of the present application may be a retractable structure, that is, the sealing device 250 may be a structure such as a sleeve, and the end thereof that is not connected to the housing 210 may be extended out of the receiving groove 213 in a direction away from the housing 210, thereby filling the gap between the covering member and the surface of the mounting opening, and in the storage state, may be retracted into the receiving groove 213 without taking up space.

[0052] In order to further improve the sealing effect, the present application provides a sealing layer on the outer surface of the sealing device 250 and / or the inner wall of the receiving groove 213, wherein the material of the sealing layer can be a soft material such as silicone, sponge or rubber, and the sealing layer can be adhered to the outer surface of the sealing device 250 and the inner wall of the receiving groove 213 by glue. When the shielding member moves down into the receiving groove 213, the sealing layer contacts the surface of the shielding member to further prevent air leakage, or when the sealing device 250 is in a sealed state, the surface of the shielding member and the installation port contacts the sealing layer to prevent air leakage, thereby improving energy efficiency.

[0053] The above descriptions are only optional embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention's specification and drawings, or directly / indirectly applied in other related technical fields, are included in the patent protection scope of the present invention.
