Detailed implementation mode

[0034] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals denote 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 and are intended to explain the present invention, and should not be construed as a limitation to the present invention.

[0035] Combined with Figure 1 and Figure 4 According to the water tank assembly 100 of the embodiment of the present invention, which is used for a dishwasher, it includes: a water tank 10 and a heat exchanger 20. The water tank 10 includes a box body 11. The box body 11 has an installation groove 101. The inner wall of the installation groove 101 is provided with a water inlet port 12 and a water outlet port 13. The heat exchanger 20 is arranged in the installation groove 101. The heat exchanger 20 includes a shell 21, a water inlet end 22 and a water outlet end 23. The water inlet end 22 and the water outlet end 23 are arranged at opposite ends of the shell 21. The water inlet end 22 is communicated with the water inlet port 12, and the water outlet end 23 is communicated with the water outlet port 13. That is to say, by integrating the installation of the water tank 10 and the heat exchanger 20 together, the water tank assembly 100 is formed. Thus, the water in the water tank 10 can be heat-exchanged to improve the energy recovery effect. Specifically, an installation groove 101 suitable for installing the heat exchanger 20 is reserved on the water tank 10. When the heat exchanger 20 is installed in the installation groove 101, the water inlet end 22 of the heat exchanger 20 can be opposite to the water inlet port 12 in the installation groove 101, and the water outlet end 23 can be opposite to the water outlet port 13 in the installation groove 101. Thus, the water in the water tank 10 can enter the heat exchanger 20 for heat exchange and then be discharged. In application, installing the heat exchanger 20 on the water tank 10 can reduce the manufacturing difficulty of the water tank assembly 100, and can also facilitate the sealing detection during the manufacturing process of the heat exchanger 20, improving the quality of the heat exchanger 20. When the heat exchanger 20 needs to be repaired, the heat exchanger 20 can be directly disassembled from the water tank 10, which is convenient for maintenance and repair and helps to reduce the use cost.

[0036] According to the water tank assembly 100 of the embodiment of the present utility model, by installing the heat exchanger 20 on the water tank 10, the manufacturing cost of the water tank assembly 100 can be reduced, and it is convenient for maintenance and repair.

[0037] Among them, the heat exchanger 20 and the water tank 10 are of a split structure. In this way, the water tank 10 and the heat exchanger 20 can be manufactured separately, and the heat exchanger 20 is detachably connected to the water tank 10, which is convenient for maintenance.

[0038] Combined Figure 1 with Figure 2 , in some embodiments of the present utility model, the water tank 10 extends in the vertical direction, the heat exchanger 20 extends in the same direction as the water tank 10, and the heat exchanger 20 is arranged in the installation groove 101 in the vertical direction, which can improve the compactness of the water tank assembly 100. Generally, the volume of the water tank 10 is large, and the volume of the heat exchanger 20 is small. The heat exchanger 20 extends in the same direction as the water tank 10, and the heat exchanger 20 is installed on the water tank 10 along the extension direction of the water tank 10. In this way, the overall structure changes little after the heat exchanger 20 is installed on the water tank 10, which is beneficial to space layout.

[0039] It should be noted that the vertical direction can be the up and down direction. Refer to Figure 1 , the heat exchanger 20 extends in the vertical direction or the up and down direction. On the one hand, it can be convenient to adapt to the structure of the water tank 10 and improve the overall structural compactness of the water tank assembly 100; on the other hand, it can also improve the heat exchange effect of the heat exchanger 20. During the heat exchange process, the vertically arranged heat exchanger 20 enables the heat exchange medium to fill the heat exchanger 20 based on gravity, and the heat exchanger 20 extending in the vertical direction can make the heat exchange medium fully contact with the heat exchanger 20, improving the heat exchange effect.

[0040] According to the water tank assembly 100 of the embodiment of the present utility model, the water tank 10 extends in the vertical direction, the heat exchanger 20 extends in the vertical direction, and the heat exchanger 20 is installed on the water tank 10 in the vertical direction. The water inlet end 22 and the water outlet end 23 of the heat exchanger 20 are arranged at opposite ends of the housing 21 along the length direction. In this way, when the heat exchanger 20 is installed in the installation groove 101 in the vertical direction, the water inlet end 22 and the water outlet end 23 can be directly matched with the water inlet port 12 and the water outlet port 13, thus facilitating quick installation and disassembly. Specifically, in the vertical direction, there is a gap between the heat exchanger 20 and the inner wall of the installation groove 101, and the heat exchanger 20 is movably arranged in the installation groove 101 along the vertical direction or the length direction of the housing 21. That is to say, the gap between the heat exchanger 20 and the installation groove 101 can provide an installation space for the heat exchanger 20. During assembly, the heat exchanger 20 can be placed in the installation groove 101 and the position of the heat exchanger 20 can be adjusted by moving it in the vertical direction, and the assembly between the water inlet end 22 and the water inlet port 12 or the water outlet end 23 and the water outlet port 13 can be adjusted to realize the connection between the water inlet end 22 and the water inlet port 12 and the connection between the water outlet end 23 and the water outlet port 13, thereby realizing the assembly of the heat exchanger 20.

[0041] Furthermore, in order to improve the stability of the heat exchanger 20 after assembly, in Figure 7 some embodiments of the present utility model, the water tank assembly 100 further includes a fixing block 30. The fixing block 30 is arranged in the gap between the heat exchanger 20 and the inner wall of the installation groove 101 and is sleeved on the outer periphery of the water inlet end 22 or the water outlet end 23. The fixing block 30 can fix the water inlet end 22 and the water outlet end 23 after assembly, thereby improving the connection stability and being beneficial to improving the operation stability of the water tank assembly 100. In other words, the position of the heat exchanger 20 can be fixed by the fixing block 30 after the heat exchanger 20 is assembled.

[0042] Of course, it can also be that the fixing block 30 can fill the gap between the heat exchanger 20 and the inner wall of the installation groove 101, thereby improving the overall structural stability of the water tank assembly 100 after the heat exchanger 20 is assembled.

[0043] More specifically, in some embodiments of the present utility model, in Figure 4, the water inlet end 22 is arranged at the second end of the housing 21 in the vertical direction, and the water outlet end 23 is arranged at the first end of the housing 21 in the vertical direction. The distance from the water inlet end 22 to the first end of the housing 21 is L2, and the distance from the water inlet port 12 to the water outlet port 13 is L1. Among them, L2 is less than L1. Thus, the heat exchanger 20 is easily installed in the installation groove 101, thereby facilitating assembly. Specifically, during assembly, the water outlet end 23 can be first extended into the installation groove 101 and cooperate with the water outlet port 13 in the installation groove 101, and then the housing 21 and the water inlet port 12 are extended into the installation groove 101. Since L2 is less than L1, the heat exchanger 20 can enter the installation groove 101.

[0044] Furthermore, the distance from the water inlet end 22 to the water outlet end 23 can be L3, and L3 is not less than L1. That is to say, the overall length of the heat exchanger 20 is not greater than the length of the installation groove 101 in the vertical direction. In this way, the structural compactness after the installation of the heat exchanger 20 can be improved, the gap between the housing 21 of the heat exchanger 20 and the inner wall of the installation groove 101 can be reduced, so that the heat exchanger 20 is not easily moved or shaken in the installation groove 101, which is beneficial to improving the structural stability after assembly.

[0045] For the heat exchanger 20 according to some embodiments of the present invention, the water inlet end 22 is arranged at the lower end of the housing 21, and the water outlet end 23 is arranged at the upper end of the housing 21. When in use, the heat exchange medium enters from the lower end of the heat exchanger 20 and exits from the upper end.

[0046] More specifically, in some embodiments of the present invention, in combination with Figure 4 and Figure 7 , the water inlet end 22 extends into the water inlet port 12, and the water outlet end 23 extends into the water outlet port 13, which can improve the fitting tightness between the heat exchanger 20 and the water tank 10 and the structural stability after connection, and is also convenient for assembly.

[0047] Furthermore, in some embodiments of the present invention, the water tank assembly 100 further includes a sealing ring. The sealing ring is sleeved on the outer periphery of the water inlet end 22, and the sealing ring seals between the water inlet end 22 and the water inlet port 12, which improves the stability after the connection between the water inlet end 22 and the water inlet port 12, and can also improve the sealing effect at the water inlet, avoiding water leakage.

[0048] The sealing ring sleeve can be sleeved on the outer periphery of the water outlet end 23, and the sealing ring seals between the water outlet end 23 and the water outlet port 13, which improves the stability after the connection between the water outlet end 23 and the water outlet port 13, and can also improve the sealing effect at the water outlet, avoiding water leakage.

[0049] Of course, it can also be that the sealing ring is respectively sleeved on the outer peripheries of the water inlet end 22 and the water outlet end 23, which can improve the connection stability and sealing performance between the heat exchanger 20 and the water tank 10.

[0050] As Figures 4 to 7 shows the assembly process of the heat exchanger 20 and the water tank 10 from the disassembled state to the completed installation. Specifically, during assembly, the heat exchanger 20 can be tilted appropriately. First, insert the water outlet end 23 into the water outlet port 13, and then insert the housing 21 and the water inlet end 22 into the installation groove 101. Refer to Figure 5 , fully insert the water outlet end 23 into the water outlet port 13 so that the upper end of the housing 21 contacts the top wall of the installation groove 101. At this time, the gap a between the lower end of the housing 21 of the heat exchanger 20 and the bottom wall of the installation groove 101 increases, and the water inlet end 22 can enter the receiving groove. At this time, the heat exchanger 20 completely enters the installation groove 101. Combining Figure 6 , move the heat exchanger 20 downward so that the water inlet end 22 can be inserted into the water inlet port 12 at the bottom wall of the installation groove 101. There is a gap b between the upper end of the housing 21 and the inner wall of the installation groove 101, and a part of the water outlet end 23 can still be inserted into the water outlet port 13. At this time, the water inlet end 22 and the water outlet end 23 of the heat exchanger 20 are communicated with the water inlet port 12 and the water outlet port 13 of the water tank 10. Combining Figure 7 , sleeved the fixing block 30 on the outer periphery of the water inlet end 22, and the fixing block 30 is assembled at the gap between the upper end of the housing 21 and the inner wall of the installation groove 101, which can prevent the heat exchanger 20 from moving in the vertical direction after assembly and improve the structural stability after assembly.

[0051] Specifically, combining Figure 4 , in some embodiments of the present invention, the water tank 10 includes a first water inlet pipe 121 and a second water inlet pipe 122. One ends of the first water inlet pipe 121 and the second water inlet pipe 122 are configured to form a water inlet port 12. The water inlet end 22 includes a first inlet pipe 223 and a second inlet pipe 224. The first water inlet pipe 121 is connected to the first inlet pipe 223, and the first inlet pipe 223 extends into the first water inlet pipe 121. A first sealing ring 41 is provided between the first water inlet pipe 121 and the first inlet pipe 223 to improve the connection tightness and the sealing effect. The second water inlet pipe 122 is connected to the second inlet pipe 224, and the second inlet pipe 224 extends into the second water inlet pipe 122. A second sealing ring 42 is provided between the second inlet pipe 224 and the second water inlet pipe 122. Among them, the first water inlet pipe 121 and the second water inlet pipe 122 are arranged side by side, and the first inlet pipe 223 and the second inlet pipe 224 are arranged side by side, which is convenient for assembly, that is, two water inlet pipes can be connected simultaneously.

[0052] In some embodiments of the present utility model, the water tank 10 includes a first water outlet pipe 131 and a second water outlet pipe 132. One ends of the first water outlet pipe 131 and the second water outlet pipe 132 are configured to form a water outlet port 13. The water outlet end 23 includes a first outflow pipe 233 and a second outflow pipe 234. The first water outlet pipe 131 is connected to the first outflow pipe 233. The first outflow pipe 233 extends into the first water outlet pipe 131, and a third sealing ring 43 is provided between the first water outlet pipe 131 and the first outflow pipe 233. The second water outlet pipe 132 is connected to the second outflow pipe 234. The second outflow pipe 234 extends into the second water outlet pipe 132, and a fourth sealing ring 44 is provided between the second outflow pipe 234 and the second water outlet pipe 132. Wherein, the first water outlet pipe 131 and the second water outlet pipe 132 are arranged side by side, and the first outflow pipe 233 and the second outflow pipe 234 are arranged side by side, which is convenient for assembly, that is, two inlet pipes can be connected simultaneously.

[0053] Specifically, grooves can be provided on the outer peripheries of the inlet pipe and the outlet pipe of the heat exchanger 20. A part of the seal is arranged in the groove, and a part protrudes from the groove. After the inlet pipe and the outlet pipe extend into the water inlet port 12 and the water outlet port 13, the seal deforms so that the inlet pipe and the outlet pipe are in interference fit with the water tank 10.

[0054] In some embodiments of the present utility model, the heat exchanger 20 further includes a heat exchange part 25. The heat exchange part 25 is arranged in the housing 21. The heat exchange part 25 forms a first flow channel and a second flow channel in the housing 21. The first flow channel communicates with the first inlet pipe 223 and the first outflow pipe 233, and the second flow channel communicates with the second inlet pipe 224 and the second outflow pipe 234. The first flow channel and the second flow channel are arranged at intervals, whereby two heat exchange flow channels can be formed in the heat exchanger 20, and the two heat exchange flow channels can exchange heat with each other. Specifically, the first medium enters the first inlet pipe 223 from the first water inlet pipe 121, is heated through the first flow channel, and is discharged from the first water outlet pipe 131 and the first outflow pipe 233; the second medium enters the second inlet pipe 224 from the second water inlet pipe 122, is heated through the second flow channel, and is discharged from the second water outlet pipe 132 and the second outflow pipe 234.

[0055] The dishwasher according to the embodiment of the present utility model includes the aforementioned water tank assembly 100. By applying the aforementioned water tank assembly 100 to the dishwasher, it is convenient to repair and maintain the dishwasher and improve its durability.

[0056] Specifically, the dishwasher further includes a water cup which can communicate with the water tank 10, and then supply water into the water cup to achieve the cleaning of tableware. Among them, the second inlet pipe 224 and the second outlet pipe 234 are in communication with the water in the water cup. Thus, the high-temperature washing medium in the water cup can flow through the second inlet pipe 224 and the second outlet pipe 234 in the second flow channel of the heat exchange part 25. The first inlet pipe 223 and the first outlet pipe 233 are in communication with the water in the water tank 10. In this way, the low-temperature washing medium in the water tank 10 can flow in the first flow channel of the heat exchange part 25, and then the heat exchange between the high-temperature washing medium in the water cup and the low-temperature washing medium in the water tank 10 is realized, and the waste heat recovery of the high-temperature washing medium in the water cup is achieved.

[0057] Among them, the washing medium in the water cup of the dishwasher is a washing medium with a relatively high temperature, and the washing medium in the water tank 10 is a washing medium with a relatively low temperature. Therefore, through the above heat exchange cycle, the temperature of the washing medium in the water tank 10 is increased, that is, the waste heat recovery of the washing medium in the dishwasher is realized, the heat utilization rate of the dishwasher is improved, and the energy consumption of the dishwasher is reduced. Specifically, the washing medium in the water cup is heated during the main washing stage of the dishwasher, so the temperature is relatively high.

[0058] It can be understood that the dishwasher includes at least a main washing stage and a rinsing stage. In the main washing stage, the washing medium is conveyed into the water cup of the dishwasher and heated to improve the cleaning effect on the kitchen utensils in the water cup; in the rinsing stage, clean water is used to wash the kitchen utensils to improve the cleaning degree. Among them, the water used in the rinsing stage is heated after heat exchange with the high-temperature water in the main washing stage, and then the rinsing effect on the kitchen utensils is improved, and the rinsing time is shortened.

[0059] Its working process is as follows: after the waste heat recovery program starts, the high-temperature water enters the second inlet pipe 224 through the external connecting pipe, connects the high-temperature water into the heat exchange part 25 of the housing 21, flows through the second flow channel, and flows out through the second outlet pipe 234 and enters the pipeline system on the high-temperature side; at the same time, the low-temperature water enters the first inlet pipe 223 through the external connecting pipe, connects the low-temperature water into the first flow channel, and flows out through the first outlet pipe 233 and enters the pipeline system on the low-temperature side. Optionally, it can also be that the low-temperature water flows in the second flow channel and the high-temperature water flows in the first flow channel.
