Abstract
Description
Technical Field
[0001] This application relates to, but is not limited to, the field of heat pump equipment technology, specifically referring to a heat pump water heater. Background Technology
[0002] An integrated heat pump water heater, such as Figure 1 and Figure 2 As shown, the heat pump unit is located above the water tank assembly. A drain nozzle 21 is located on the side wall of the water collection tray 20 of the heat pump unit. The evaporator 10, piping, and compressor of the heat pump unit are all located on the water collection tray 20. During operation, the evaporator 10, piping, and compressor all produce condensate. Because the drain nozzle 21 is located on the side wall of the water collection tray 20, the condensate in the water collection tray 20 cannot be completely drained, leaving a small amount of residue. This residue can easily lead to bacterial growth. When the heat pump water heater is installed outdoors, plant seeds may also enter the heat pump unit and remain in the area of residual condensate, potentially causing the seeds in this area to germinate and grow into plants.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be arbitrarily combined with each other.
[0026] The heat pump water heater provided in this application embodiment, such as Figures 3 to 6 As shown, it includes: a water tank shell 100 with an upper opening, and an mounting hole 110 on the upper part of the side wall of the water tank shell 100; a water receiving tray 200, which is installed on the upper part of the water tank shell 100, with the mounting hole 110 located below the water receiving tray 200, and a drain nozzle 210 located inside the water tank shell 100 on the bottom wall of the water receiving tray 200; and an adapter 300, which is located at the mounting hole 110 and has a drainage channel, with the first end of the drainage channel facing the inside of the water tank shell 100 and connected to the drain nozzle 210, and the second end of the drainage channel facing the outside of the water tank shell 100 and configured to connect to a drain pipe.
[0027] In this heat pump water heater, the drain nozzle 210 is located on the bottom wall of the water tray 200. This makes it easier for the condensate on the water tray 200 to be completely drained from the water tray 200 through the drain nozzle 210, and then discharged to the set position through the drain channel and drain pipe. This design can better prevent the growth of bacteria and plants in the water tray 200. Moreover, the mounting hole 110 will not have much impact on the strength of the peripheral wall of the water tank shell 100.
[0028] In some embodiments, such as Figure 5 and Figure 6 As shown, the bottom wall of the water receiving tray 200 is provided with a drainage groove 220, and a drain nozzle 210 is provided on the bottom wall of the drainage groove 220 and extends downward into the outer shell 100 of the water tank. The condensate that falls into the water receiving tray 200 is collected in the drainage groove 220, and then discharged from the drainage groove 220 through the drain nozzle 210, and then discharged to a set position through the drainage channel and the drain pipe in sequence, so as to realize the complete discharge of condensate in the water receiving tray 200.
[0029] In some embodiments, such as Figure 5 and Figure 6 As shown, the inner bottom surface of the drain trough 220 includes an inclined surface, and the drain nozzle 210 is located in the low-lying part of the inclined surface, which can better ensure that all the condensate in the drain trough 220 can be drained.
[0030] In some embodiments, such as Figure 5 and Figure 6 As shown, the drain nozzle 210 is inserted into the first end of the drain channel, that is, the inner diameter of the lower end of the drain nozzle 210 is smaller than the inner diameter of the first end of the drain channel, so that the condensate in the drain groove 220 can be discharged more smoothly from the drain nozzle 210 to the drain channel.
[0031] In some embodiments, such as Figures 4 to 6 As shown, the drain nozzle 210 includes a vertically arranged first pipe section, and the drain channel includes a vertically arranged second pipe section 310 and a horizontally arranged third pipe section 320. The first pipe section is located above the second pipe section 310, and its lower end is inserted into the upper end of the second pipe section 310. The first end of the third pipe section 320 faces the interior of the water tank shell 100 and is connected to the lower end of the second pipe section 310. The second end of the third pipe section 320 faces the exterior of the water tank shell 100 and is configured to connect to the drain pipe. This design facilitates connecting the drain pipe to the second end of the third pipe section 320 from the exterior of the water tank shell 100. The second end of the drain channel is the second end of the third pipe section 320, and the first section of the drain channel is the upper end of the second pipe section 310.
[0032] In some embodiments, such as Figures 4 to 6As shown, the adapter 300 is provided with a receiving groove 330. The opening of the receiving groove 330 faces the outside of the water tank shell 100, and the bottom of the receiving groove 330 is located inside the water tank shell 100. The first end of the drainage channel (i.e. the upper end of the second pipe section 310) is located on the side of the bottom of the receiving groove 330 away from the opening and inside the water tank shell 100. The second end of the drainage channel (i.e. the second end of the third pipe section 320) is located inside the receiving groove 330. That is, the second end of the drainage channel is hidden inside the receiving groove 330. In this way, the peripheral wall of the receiving groove 330 will protect the second end of the drainage channel and prevent the second end of the drainage channel from being damaged by impact from external objects.
[0033] In some embodiments, such as Figures 4 to 6 As shown, the groove of the receiving slot 330 has an outwardly bent mounting edge 340. The mounting edge 340 is located outside the water tank shell 100 and abuts against the outer end face of the mounting hole 110 (facing the outside of the water tank shell 100), thus fixing the adapter 300 at the mounting hole 110. Alternatively, the mounting edge 340 can have a through hole, and the outer end face of the mounting hole 110 can have a screw hole. A screw passes through the through hole and is screwed into the screw hole, thus fixing the adapter 300 at the mounting hole 110. This solution is simple in structure and easy to implement. Another option is that the outer end face of the mounting hole 110 has a rivet nut, and the screw hole is located on the rivet nut. Or, the mounting edge 340 can have a buckle, and the outer end face of the mounting hole 110 can have a locking position. The buckle engages with the locking position, thus fixing the adapter 300 at the mounting hole 110. This solution is also simple in structure and easy to implement. All of the above can achieve the purpose of this application, and their purpose has not deviated from the design concept of this utility model. They will not be repeated here, and should all fall within the protection scope of this application.
[0034] In some embodiments, such as Figure 3 and Figure 5 As shown, the heat pump water heater also includes an inner tank 400, which is located inside the outer shell 100 of the water tank. The top surface of the inner tank 400 faces the water receiving tray 200 and is a convex curved surface, that is, the top surface of the inner tank 400 is high in the middle and low around the edges. In this way, the area of the upper part of the outer shell 100 near the side wall of the outer shell 100 forms a space to accommodate the adapter 300, so that the outer shell 100 of the water tank does not need to be raised.
[0035] The installation process of the water tank shell 100, the water receiving tray 200 and the adapter 300 is as follows: the water receiving tray 200 is installed on the upper part of the water tank shell 100; the adapter 300 is inserted into the mounting hole 110, and the lower end of the first pipe section is inserted into the upper end of the second pipe section 310; then the mounting edge 340 is fixed on the outer end face of the mounting hole 110 facing the outside of the water tank shell 100.
[0036] In some embodiments, the drain pipe is provided as a flexible hose, such as... Figure 3 and Figure 5 As shown in Figure 5 , a compressor 500 and a heat exchanger 600 are provided on the water receiving tray 200. The compressor 500 can be set as a horizontal compressor or a vertical compressor.
[0037] In summary, for the technical solution provided by the embodiment of the present application, the drain nozzle is located at the bottom wall of the water receiving tray, so that the condensed water on the water receiving tray can be more easily discharged from the drain nozzle completely out of the water receiving tray, and then sequentially discharged to a set position through the drain channel and the drain pipe. This solution can better avoid the growth of bacteria and plants in the water receiving tray.
