DETAILED DESCRIPTION

[0043] The embodiments of the present application are described in detail below, examples of which are shown in the drawings, wherein the same or similar notations represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary only, and are used to explain the present application, and cannot be understood as a limitation of the present application.

If it is described as first, second, it is only used for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features or the sequence of indicated technical features.

[0046] In the description of the present application, unless otherwise explicitly limited, the words such as setting, installing, connecting, assembling, cooperating, etc. should be understood in a broad sense, and the person skilled in the art can reasonably determine the specific meaning of the above words in the present application according to the specific content of the technical scheme.

[0047] In the related art, the bottom plate of the existing heat pump equipment is generally a sheet metal part or a plastic part. However, when the bottom plate contains the condensed water generated by the heat pump equipment, the heat transfer coefficient of the sheet metal part or the plastic part is relatively large, and the heat insulation performance is poor. The cold energy of the condensed water in the bottom plate will be transferred to the bottom wall of the bottom plate. In a high-temperature and high-humidity use environment, the bottom wall of the bottom plate will generate condensed water. After the heat pump equipment runs for a long time, the condensed water will drip to the ground, causing water accumulation on the ground, which is inconvenient for users. In a low-temperature use environment, the cold energy outside the heat pump equipment will be transferred to the inside of the bottom plate, which will cause the condensed water in the bottom plate to freeze without being discharged in time, affecting the drainage and the normal operation of the heat pump equipment.

[0048] To solve the above problems, with reference to Figure 1 and Figure 2 The utility model discloses a first aspect of embodiment provides a bottom plate assembly, including water receiving tray 100 bottom plate body 140 and heat preservation layer 120, water receiving tray 100 is used for receiving the condensed water of heat pump equipment, and water receiving tray 100 is equipped with first drain hole 103, and bottom plate body 140 is located below water receiving tray 100, and bottom plate body 140 is equipped with second drain hole 143, and heat preservation layer 120 is arranged between water receiving tray 100 and bottom plate body 140, and heat preservation layer 120 is equipped with third drain hole 122, wherein first drain hole 103, third drain hole 122 and second drain hole 143 are sequentially communicated. In this example, on the horizontal projection plane, the projections of the first drain hole 103, the third drain hole 122 and the second drain hole 143 at least partially overlap. For example, the projection of the second drain hole 143 falls within the projection of the first drain hole 103, and the projections of the first drain hole 103 and the second drain hole 143 both fall within the projection of the third drain hole 122. This can reduce the drainage resistance and speed up the drainage rate. It can be understood that by arranging the heat preservation layer 120 between the water receiving tray 100 and the bottom plate body 140, the heat transfer speed between the inside of the water receiving tray 100 and the bottom wall of the bottom plate body 140 can be reduced due to the smaller heat transfer coefficient of the heat preservation layer 120. In a high-temperature and high-humidity environment, the amount of cold energy transferred from the condensed water in the water receiving tray 100 to the bottom wall of the bottom plate body 140 can be reduced, thereby reducing the risk of condensed water being generated on the bottom wall of the bottom plate body 140 and preventing the condensed water from dripping to the ground, effectively improving the user experience. At the same time, in a low-temperature environment, the amount of cold energy transferred from the outside of the bottom plate assembly to the inside of the water receiving tray 100 can be reduced, thereby reducing the risk of the condensed water in the water receiving tray 100 freezing and ensuring normal drainage and improving the operation reliability of the heat pump equipment.

[0049] Specifically, the water receiving tray 100 is a sheet metal part, the bottom disc body 140 is a plastic part, and the thermal insulation layer 120 is made of EPP foam material (i.e., polypropylene foaming resin). It can be understood that, on the one hand, the heat exchanger in the heat pump device is installed on the water receiving tray 100, and the sheet metal part has good structural strength and can ensure the installation stability of the heat exchanger. The thermal insulation layer 120 has a small thermal conductivity and good heat insulation effect, which can reduce the cold quantity transmission speed between the water receiving tray 100 and the bottom disc body 140. The thermal conductivity of the bottom disc body 140 made of plastic material is lower than that of the water receiving tray 100 made of sheet metal material, so the cold quantity transmission speed of the condensate water in the heat pump device to the outer bottom wall of the bottom disc body 140 can be effectively reduced. In a high-temperature and high-humidity environment, the risk of condensate water on the bottom wall of the bottom disc body 140 can be reduced. On the other hand, the outer wall of the bottom disc body 140 away from the water receiving tray 100 faces the outside of the heat pump device. In a low-temperature environment, the bottom disc body 140 can reduce the cold quantity transmission speed from the outside of the bottom disc assembly to the water receiving tray 100, thereby reducing the risk of condensate water icing in the water receiving tray 100. At the same time, the bottom disc body 140 made of plastic parts can improve the aesthetics of the outside of the heat pump device, and the thermal insulation layer 120 made of EPP foam material is clamped between the water receiving tray 100 and the bottom disc body 140. The bottom disc body 140 can effectively protect the thermal insulation layer 120, and avoid the heat insulation failure caused by damage to the thermal insulation layer 120 during installation or transportation.

[0050] With reference to Figure 2 It can be understood that the water receiving tray 100 includes a first bottom plate 107 and a second side plate 111 connected to the outer periphery of the first bottom plate 107 and extending upward to form a cavity for containing condensate water, which can avoid the condensate water generated during the operation of the heat pump device from overflowing. Correspondingly, the bottom disc body 140 includes a second bottom plate 141 and a first side plate 144 connected to the outer periphery of the second bottom plate 141 and arranged upwardly, the first side plate 144 surrounds the outer periphery of the thermal insulation layer 120 and the water receiving tray 100, and the first side plate 144 protrudes upwardly from the water receiving tray 100, which can avoid the condensate water from overflowing.

[0051] It can be understood that the heat preservation layer 120 comprises a third bottom plate 129 and a side wall 127, the side wall 127 is connected to the outer periphery of the third bottom plate 129 and extends upward, and the side wall 127 is wrapped around the outer periphery of the second side plate 111. The first side plate 144 is wrapped around the outer periphery of the side wall 127, that is, the side wall 127 is located between the second side plate 111 and the first side plate 144. The first side plate 144 extends upward and protrudes from the second side plate 111 of the water pan 100 and the side wall 127 of the heat preservation layer 120. While avoiding the overflow of condensed water, it can reduce the speed of cold energy transmission between the second side plate 111 and the first side plate 144, which is conducive to improving the heat insulation effect. In some embodiments, the height of the side wall 127 is equal to the height of the second side plate 111 and lower than the height of the first side plate 144. When the condensed water contacts the second side plate 111, the speed of cold energy transmission between the second side plate 111 and the first side plate 144 is reduced through the side wall 127, and at the same time the first side plate 144 can provide effective protection for the side wall 127, maintaining the stability of heat insulation.

[0052] Referring to Figure 3 It can be understood that the first bottom plate 107 is provided with a first water collecting cavity 101, the first water collecting cavity 101 is located in the middle of the first bottom plate 107, and the first water collecting cavity 101 is arranged downwardly concave, so that the upper wall surface of the first water collecting cavity 101 is lower than the upper wall surface of the first bottom plate 107, and the first drain hole 103 is located in the first water collecting cavity 101. The heat exchanger is installed on the upper part of the first water collecting cavity 101, and the first water collecting cavity 101 can accommodate the condensed water dripping from the heat exchanger, so that the condensed water collected by the first water collecting cavity 101 is concentrated and discharged from the first drain hole 103, avoiding the overflow of the condensed water to the surrounding, thereby avoiding the formation of water accumulation in the water pan 100, to avoid the icing condition and maintain the operation stability of the heat pump equipment.

[0053] It can be understood that since the water pan 100 is a sheet metal part formed by stamping and processing of metal sheet material, the first water collecting cavity 101 is a downward convex structure, and the water pan 100 is downwardly stamped and formed by using a convex die to obtain the first water collecting cavity 101. Therefore, the outer side bottom wall of the water pan 100 has a first convex part 113 corresponding to the first water collecting cavity 101. Correspondingly, the heat preservation layer 120 has a recess 126, and the first convex part 113 is embedded and installed in the recess 126, which can reduce the thickness of the bottom disc assembly while forming the first water collecting cavity 101, and is conducive to improving the space utilization.

[0054] It can be understood that the bottom wall of the first water collecting cavity 101 is provided with a collecting cavity 102, the collecting cavity 102 is located in the middle of the first water collecting cavity 101, the collecting cavity 102 is provided in a downward recessed manner, so that the upper wall surface of the collecting cavity 102 is lower than the upper wall surface of the first water collecting cavity 101, which can make the condensed water collected in the first water collecting cavity 101 fall into the collecting cavity 102, and further avoid the situation that the condensed water flows to the surrounding. And the first drain hole 103 is arranged on the bottom wall of the collecting cavity 102, so that the condensed water can flow from the upper wall surface of the first bottom plate 107 to the first water collecting cavity 101 and the collecting cavity 102 in turn, and finally be discharged from the first drain hole 103, realizing timely drainage and effectively avoiding the accumulation of water in the water pan 100.

[0055] It can be understood that the first water collecting cavity 101 can be circular or rectangular in shape, and the collecting cavity 102 is arranged near any circumferential inner wall of the first water collecting cavity 101, which is beneficial to reduce the possibility of condensed water accumulating between the side wall and the bottom wall of the first water collecting cavity 101. In some embodiments, the bottom wall of the first water collecting cavity 101 is inclined downward from the circumferential inner wall of the first water collecting cavity 101 to the collecting cavity 102, which can improve the efficiency of condensed water flowing from the first water collecting cavity 101 to the collecting cavity 102, thereby effectively avoiding the occurrence of water accumulation.

[0056] It can be understood that the collecting cavity 102 can be circular or rectangular in shape. The first drain hole 103 is located near any circumferential inner wall of the first water collecting cavity 101, which is beneficial to reduce the possibility of condensed water accumulating between the circumferential inner wall and the bottom wall of the collecting cavity 102. In some embodiments, the bottom wall of the collecting cavity 102 is inclined downward from the circumferential inner wall of the collecting cavity 102 to the first drain hole 103, which can improve the efficiency of condensed water flowing from the collecting cavity 102 to the first drain hole 103, thereby effectively avoiding the occurrence of water accumulation.

[0057] In some embodiments, the collecting cavity 102 is arranged near any circumferential inner wall of the first water collecting cavity 101, the first drain hole 103 is located near any circumferential inner wall of the first water collecting cavity 101, and the first drain hole 103 and the collecting cavity 102 are close to the same circumferential inner wall of the first water collecting cavity 101. The bottom wall of the first water collecting cavity 101 is inclined downward from the circumferential inner wall of the first water collecting cavity 101 to the collecting cavity 102, and the bottom wall of the collecting cavity 102 is inclined downward from the circumferential inner wall of the collecting cavity 102 to the first drain hole 103, so that the condensed water can flow along the inclined wall surface to the first drain hole 103, thereby improving the drainage efficiency and avoiding the occurrence of water accumulation.

[0058] It can be understood that the water collecting cavity 102 is formed by stamping, and thus the second protrusion 115 protrudes downward on the first protrusion 113. Correspondingly, the heat insulation layer 120 has a third drain hole 122 penetrating the bottom wall of the recess 126, and the second protrusion 115 is embedded in the third drain hole 122, so as to reduce the thickness of the bottom disc assembly when the first drain hole 103 and the third drain hole 122 are communicated, and improve the space utilization.

[0059] It can be understood that the water collecting cavity 102 is formed by stamping, and thus the second protrusion 115 protrudes downward on the first protrusion 113. Correspondingly, the heat insulation layer 120 has a third drain hole 122 penetrating the bottom wall of the recess 126, and the second protrusion 115 is embedded in the third drain hole 122, so as to reduce the thickness of the bottom disc assembly when the first drain hole 103 and the third drain hole 122 are communicated, and improve the space utilization.

[0060] With reference to Figure 6 , the inner diameter of the first flow guide part 104 decreases from top to bottom, like an inclined surface or an arc surface, which can guide the condensed water to be quickly discharged. It can be understood that the first flow guide part 104 is a downward flange formed on the periphery of the first drain hole 103 in the stamping process, and thus the inner wall of the first flow guide part 104 is funnel-shaped, which can further concentrate the condensed water to the first drain hole 103, and improve the drainage efficiency.

[0061] It can be understood that the first water collecting cavity 101, the water collecting cavity 102, the first drain hole 103 and the first flow guide part 104 are integrally formed by stamping, and thus the side wall of the first water collecting cavity 101 and the top wall of the first bottom plate 107, the circumferential inner side wall of the water collecting cavity 102 and the bottom wall of the first water collecting cavity 101, and the circumferential inner side wall of the water collecting cavity 102 and the bottom wall of the water collecting cavity 102 all have arc surfaces 114. When the condensed water flows through the first bottom plate 107, the first water collecting cavity 101, the water collecting cavity 102 and then the first drain hole 103, it passes through multiple arc surfaces 114, which can reduce the flow resistance of the condensed water, improve the drainage efficiency and reduce the possibility of water accumulation.

[0062] It can be understood that the bottom wall of the first water collecting cavity 101 is also provided with a plurality of auxiliary drainage holes 106, which are arranged at intervals and penetrate the upper and lower wall surfaces of the first bottom plate 107 in the up-down direction. The auxiliary drainage holes 106 are located in the outer peripheral region of the confluence cavity 102, and along the length direction of the water pan 100, the auxiliary drainage holes 106 are arranged in at least two rows along the width direction of the water pan 100, and thus the condensed water in the first water collecting cavity 101 can also be discharged through the auxiliary drainage holes, which helps to improve the drainage efficiency and thus reduce the occurrence of water accumulation.

[0063] Correspondingly, with reference to Figure 7 , the heat preservation layer 120 is provided with a water guide groove 123, which is located on the bottom wall of the recess 126 and communicates the plurality of auxiliary drainage holes 106 with the third drainage hole 122, and the guide direction of the water guide groove 123 is towards the third drainage hole 122. In some embodiments, the water guide groove 123 extends in the width direction of the heat preservation layer 120 within the recess 126 and communicates the plurality of third drainage holes 122, and along the width direction of the heat preservation layer 120, the water guide groove 123 is provided with at least two, which can receive the condensed water discharged from the plurality of auxiliary drainage holes 106. In some embodiments, the bottom wall of the water guide groove 123 is downwardly inclined from the inner peripheral wall of the recess 126 to the third drainage hole 122, which can improve the efficiency of the condensed water flowing on the drainage groove to the third drainage hole 122, thereby avoiding water accumulation.

[0064] With reference to Figure 5 and Figure 6 It can be understood that the water pan 100 further comprises a plurality of second flow guide portions 105, which are correspondingly connected to the periphery of the plurality of auxiliary drainage holes 106, and the second flow guide portion 105 is arranged around the auxiliary drainage hole 106 and extends downwardly, and the inner wall surface of the second flow guide portion 105 is connected to the upper wall surface of the first water collecting cavity 101. Therefore, during the drainage process, the condensed water flowing into the auxiliary drainage hole 106 can flow downwardly along the inner wall of the second flow guide portion 105, thereby improving the drainage efficiency and avoiding water accumulation.

[0065] It can be understood that the inner diameter of the second flow guide portion 105 decreases from top to bottom, such as a slope or an arc surface, which can guide the condensed water to be discharged quickly. It can be understood that the plurality of auxiliary drainage holes 106 and the second flow guide portion 105 can be formed simultaneously during the stamping forming process of the water pan 100, and the second flow guide portion 105 is a downward flange formed on the periphery of the auxiliary drainage hole 106, and thus the inner wall thereof forms a funnel shape, which can make the condensed water further discharge downwardly, thereby improving the drainage efficiency.

[0066] With reference to Figure 7It can be understood that the heat preservation layer 120 comprises a third bottom plate 129 and a side wall 127, the side wall 127 is arranged upwards from the outer periphery of the third bottom plate 129, so that the inner peripheral wall of the side wall 127 and the upper wall surface of the third bottom plate 129 form the flow guide cavity 121. It can be understood that the water pan 100 is installed in the flow guide cavity 121 of the heat preservation layer 120, and the outer side bottom wall of the water pan 100 towards the heat preservation layer 120 abuts against the bottom wall of the flow guide cavity 121. Since the water pan 100 formed by stamping has shape and size errors, there is a gap between the outer side bottom wall of the water pan 100 and the bottom wall of the flow guide cavity 121, and air is stored in the gap. The air in this part can reduce the cold quantity transmission speed of the water pan 100 and the heat preservation layer 120. Similarly, there is a gap between the outer peripheral wall of the second side plate 111 of the water pan 100 and the inner peripheral wall of the side wall 127, and air is stored in the gap. Therefore, the cold quantity transmission speed between the second side plate 111 and the side wall 127 can be reduced, and the possibility of the cold quantity of the condensed water being transmitted to the surrounding can be reduced.

[0067] With reference to Figure 7 and Figure 9 It can be understood that the bottom wall of the flow guide cavity 121 is inclined downward from the direction of the inner periphery of the flow guide cavity 121 to the third drain hole 122. Specifically, the bottom wall region of the flow guide cavity 121 around the recess 126 is an inclined surface, which comprises a first inclined surface 130 and a second inclined surface 131. The first inclined surface 130 is located on both sides of the recess 126 along the length direction of the heat preservation layer 120, and the second inclined surface 131 is located on both sides of the second inclined surface 131 along the width direction of the heat preservation layer 120. It can be understood that one end of the first inclined surface 130 close to the side wall 127 is higher than the other end close to the recess 126, and one end of the second inclined surface 131 close to the side wall 127 is higher than the other end close to the recess 126. Therefore, the bottom wall of the flow guide cavity 121 forms a funnel shape, so that the condensed water can be quickly discharged to the recess 126. It can be understood that there is a gap between the first inclined surface 130 and the second inclined surface 131 and the outer side bottom wall of the water pan 100, which can accommodate air. The air in this part can reduce the cold quantity transmission speed of the water pan 100 and the heat preservation layer 120, which is beneficial to improve the heat insulation effect.

The air in this part can reduce the heat transfer speed between the heat preservation layer 120 and the bottom disc body 140, thereby helping to maintain good heat insulation effect. Similarly, a gap is formed between the outer peripheral wall of the side wall 127 of the heat preservation layer 120 and the inner peripheral wall of the first side plate 144, and air is stored in the gap.
