[0024] Next, the technical solutions in the embodiments of the present invention will be described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Other technical solutions obtained by those skilled in the art without creative efforts fall within the protection scope of the present invention. In addition, it should be understood that the following terms indicating orientation or positional relationships, such as "upper", "lower", "left", "right", "longitudinal", "transverse", "inner", "outer", "vertical", "horizontal", "top", "bottom", etc., are only based on the orientation or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device / element referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention.

[0025] As Figures 1-12 shown, it includes a disk body 100, a first heating tube 101, and a second heating tube 102. The disk body 100 has a heating channel 103. The first heating tube 101 surrounds a part of the channel wall of the heating channel 103, and the second heating tube 102 surrounds another part of the channel wall of the heating channel 103. The first heating tube 101 and the second heating tube 102 have a positional difference in the axial direction of the disk body 100.

[0026] The heating plate is used to heat the fluid of a household appliance to improve the working efficiency of the relevant household appliance. For example, when the heating plate is used in a dishwasher, it heats the fluid flowing through the dishwasher, so that the relevant detergent can clean tableware and other kitchen utensils in the fluid at a certain temperature, thereby improving the cleaning efficiency of the dishwasher; another example is that when the heating plate is used in a washing machine, it heats the fluid in the washing machine, so that the relevant detergent can clean clothes in the fluid at a certain temperature, improving the cleaning efficiency of the washing machine. In a preferred implementation manner, the heating plate is used in a dishwasher and is integrated with the transfer pump of the dishwasher to heat the fluid flowing through the pump.

[0027] The first heating tube 101 and the second heating tube 102 have a positional difference along the axial direction of the disk body 100, so that the heating sources can be dispersed to a certain extent, enabling the fluid flowing through the heating channel 103 to be heated in all directions, thereby increasing the heating efficiency of the heating disk for the fluid. Further, the overlapping portion of the two heating tubes in the same horizontal area is reduced, the probability of repeatedly heating the fluid in the same area is lowered, and the utilization rate of heat is improved.

[0028] In other embodiments, there may also be a third heating tube (not marked in the figure) or more heating tubes, which are arranged along the axial direction of the heating disk.

[0029] In one embodiment, the heating channel 103 includes a first heating channel 1031 and a second heating channel 1032. The first heating channel 1031 and the second heating channel 1032 are in communication. Define the channel side wall corresponding to the first heating channel 1031 as the first channel wall 10311, and define the channel side wall corresponding to the second heating channel 1032 as the second channel wall 10321. The first heating tube 101 surrounds at least part of the first channel wall 10311, and the second heating tube 102 surrounds at least part of the second channel wall 10321; the two heating tubes can respectively heat the fluid in the first heating channel 1031 and the second heating channel 1032.

[0030] In one embodiment, the inner diameter of the first heating channel 1031 is smaller than that of the second heating channel 1032. The heating disk has a through-flow port 1003. The first heating tube 101 and the second heating tube 102 respectively surround the through-flow port 1003. The through-flow port 1003 is in communication with the first heating channel 1031. The flow areas of the second heating channel 1032, the first heating channel 1031, and the through-flow port 1003 decrease in sequence.

[0031] The heating disk is in a disk shape. The through-flow port 1003 is located within the range surrounded by the first heating tube 101 and the second heating tube 102. The fluid enters the first heating channel 1031 from the through-flow port 1003, and then enters the second heating channel 1032 from the first heating channel 1031. In this flow path, the flow path of the fluid gradually becomes larger, and the fluid is heated by the first heating channel 1031 and the second heating channel 1032 during this process, enabling the fluid to be heated stage by stage, reducing the drawback of poor heating effect caused by the sudden increase in the flow area of the fluid after entering the heating disk from the through-flow port 1003, and thus further improving the heating efficiency of the heating disk for the fluid.

[0032] In other embodiments, the inner diameters of the first heating channel 1031 and the second heating channel 1032 can be the same. At this time, there is no obvious demarcation structure between the first heating channel 1031 and the second heating channel 1032, but the first heating channel 1031 and the second heating channel 1032 can still be distinguished according to the settings of different positions of the first heating pipe 101 and the second heating pipe 102.

[0033] In one embodiment, the first heating pipe 101 is located outside the first heating channel 1031, specifically on the outer side of the first channel wall, and the second heating pipe 102 is located outside the second cavity, specifically on the outer side of the second channel wall. The first heating pipe 101 and the second heating pipe 102 transfer heat to the fluid through the heat conduction of the disc body 100 and heat the fluid. This structure facilitates the installation and setting of the first heating pipe 101 and the second heating pipe 102. Specifically, the first heating pipe 101 can be arranged around the outer side of the first channel wall by means of welding or direct pressing, etc., and the second heating pipe 102 can also be arranged around the outer side of the second channel wall by means of welding or direct pressing, etc.

[0034] In other embodiments, the first heating pipe 101 is located inside the first heating channel 1031, specifically on the inner side of the first channel wall, and the second heating pipe 102 is located inside the second heating channel 1032, specifically on the inner side of the second channel wall. The first heating pipe 101 and the second heating pipe 102 are respectively fixed to the first channel wall and the second channel wall, so that the heat of the first heating pipe 101 and the second heating pipe 102 can be directly transferred to the fluid.

[0035] As Figures 3-5 、 Figure 7 shown, in one embodiment, the disc body 100 has a first groove portion 107 and a second groove portion 108. The first groove portion 107 and the second groove portion 108 are arranged along the axial direction of the disc body 100. At least a part of one of the first heating pipe 101 and the second heating pipe 102 is located in the space corresponding to the first groove portion 107, and at least a part of the other is located in the space corresponding to the second groove portion 108.

[0036] Furthermore, at least a part of the first heating pipe 101 is located in the space corresponding to the first groove portion 107, and at least a part of the second heating pipe 102 is located in the space corresponding to the second groove portion 108. The first heating pipe 101 and the second heating pipe 102 are respectively pressed and fixed or fixed to the first groove portion 107 and the second groove portion 108 by other means such as welding. The position of the first groove portion 107 is higher than that of the second groove portion 108. The inner wall of the first groove portion 107 is the first channel wall, and the inner wall of the second groove portion 108 is the second channel wall. Of course, in other embodiments, the positions of the first heating pipe 101 and the second heating pipe 102 can be swapped.

[0037] AsFigure 11 As shown, in another embodiment, the disk body 100 has a third groove portion 109, at least part of the first heating tube 101 and at least part of the second heating tube 102 are both located in the space corresponding to the third groove portion 109, at least part of the bottom wall of the second groove portion 108 has a slope in the axial direction of the disk body 100, and the first heating tube 101 and the second heating tube 102 are fixed to this part of the bottom wall.

[0038] At this time, the first heating tube 101 and the second heating tube 102 are located in the same groove. At least part of the bottom wall of the third groove portion 109 has a slope in the axial direction of the disk body 100. The first heating tube 101 and the second heating tube 102 are arranged on the bottom wall of this slope, so that the first heating tube 101 and the second heating tube 102 have a position difference in the axial direction of the disk body 100. Specifically, the bottom wall with this slope can be an inclined wall, a curved wall, or can also be set as a step with a position difference or other bottom walls with a position difference.

[0039] In one embodiment, the disk body 100 includes a bottom wall portion 1002 and a side wall portion 1001. The first heating channel 1031 and the second heating channel 1032 are located on the bottom wall portion 1002, that is, the first channel wall of the first heating channel 1031 and the second channel wall of the second heating channel 1032 are part of the bottom wall portion 1002. Part of the bottom wall portion 1002 protrudes to form the first heating channel 1031 and the second heating channel 1032. The bottom wall portion 1002 can be integrally formed or can be stretch-formed using aluminum or the like. The two heating tubes are arranged on the protruding part of the bottom wall portion 1002, taking into account both the heating efficiency and the radial dimension of the heating disk. Further, the protruding part of the bottom wall portion 1002 is in a conical shape, which can further reduce the dimension of the heating disk in the axial direction.

[0040] In one embodiment, the first groove portion 107 and the second groove portion 108 are distributed in a stepped manner. Define the bottom wall corresponding to the first groove portion 107 as the first wall 1071, and define the bottom wall corresponding to the second groove portion 108 as the second wall 1081. The first wall 1071 is horizontally arranged, the bottom end of the first heating tube 101 is in contact with the first wall 1071, the second wall 1081 is horizontally arranged, and the bottom end of the second heating tube 102 is in contact with the second wall 1081. In the axial direction of the disk body 100, the first wall 1071 and the second wall 1081 have a position difference.

[0041] As Figure 7As shown, the first wall 1071 and the second wall 1081 are horizontally arranged. The bottom end of the first heating tube 101 is in contact with the first wall 1071, and the bottom end of the second heating tube 102 is in contact with the second wall 1081. On the one hand, this makes the arrangement of the first heating tube 101 and the second heating tube 102 more stable. On the other hand, it ensures the heat transfer efficiency between the first heating tube 101, the second heating tube 102 and the disk body 100. It can be understood that the horizontal arrangement refers to the horizontal direction as shown in the attached drawings, and this direction also changes with different position states of the heating disk.

[0042] In another embodiment, the first wall 1071 and the second wall 1081 can also be arranged to be inclined. Specifically, both the first wall 1071 and the second wall 1081 are generally in the shape of a conical surface. Further, the first heating tube 101 has a third tube wall facing away from the connector 104, and the second heating tube 102 has a fourth tube wall facing away from the connector 104. Both the third tube wall and the fourth tube wall are generally in the shape of a conical surface. The third tube wall corresponds to the first wall 1071, and the fourth tube wall corresponds to the second wall 1081. The disk body 100 has a bottom wall portion 1002 that is generally conical, and the taper of the conical bottom wall portion 1002 is generally the same as the taper of the first wall 1071 and the second wall 1081. Compared with a planar shape, the conical bottom wall portion 1002 can have a longer installation range under the same size, so that a heating tube with a larger inner diameter can be assembled, that is, the miniaturization of the disk body 100 can be achieved while ensuring the heating power of the heating tube, which is very suitable for household electrical appliances.

[0043] In one embodiment, the first heating channel 1031 and the second heating channel 1032 are located on the side of the disk body 100 facing away from the first heating tube 101 and the second heating tube 102, and the inner diameter of the first heating channel 1031 is smaller than the inner diameter of the second heating channel 1032. The different inner diameters of the first heating channel 1031 and the second heating channel 1032 can enable the fluid to obtain different heating efficiencies, so that the fluid is heated at least twice in the flowing process, and it plays a role in alleviating the change in the size of the flow path, reducing the influence caused by insufficient heating due to a sudden increase in the flow path size or excessive heating due to a sudden decrease.

[0044] In one embodiment, the heating disk includes a connector 104. The connector 104 covers a part of the first heating tube 101 and a part of the second heating tube 102. The heating disk includes a thermostat 106 and a circuit breaker 105. The thermostat 106 and the circuit breaker 105 are arranged on the connector 104. The connector 104 has a heat insulation part 1042 and a heat conduction part 1041. There is a gap between the heat insulation part 1042 and both the first heating tube 101 and the second heating tube 102. The heat conduction part 1041 is in contact with the first heating tube 101 and the second heating tube 102. The thermostat 106 is arranged on the heat insulation part 1042, and the circuit breaker 105 is arranged on the heat conduction part 1041.

[0045] The thermostat 106 and the circuit breaker 105 can be welded to the connecting member 104 by laser welding. The circuit breaker 105 is arranged on the heat conducting portion 1041 so that it can more timely and accurately sense the temperatures of the first heating tube 101 and the second heating tube 102. When it senses that the heating temperature of the first heating tube 101 or the second heating tube 102 is higher than the preset value due to other reasons such as dry burning of the heating tube, the circuit breaker 105 immediately performs open circuit protection. The thermostat 106 is used to collect the heating temperature of the heating plate and control the heating power of the two heating tubes to adjust the heating temperature of the fluid flowing through the heating plate. The thermostat 106 is arranged on the heat insulating portion 1042 to reduce the adverse effect caused by the high-temperature heating tube transferring heat to the thermostat 106.

[0046] In one embodiment, the connecting member 104 is made of aluminum or other metal materials and is fixed to the disk body 100 by brazing. The connecting member 104 can be bent or integrally formed with a recess so that there is a gap between this part and the two heating tubes.

[0047] In one embodiment, the first heating tube 101 has a first tube wall 1011 facing the connecting member 104, and the second heating tube 102 has a second tube wall 1021 facing the connecting member 104. The first tube wall 1011 and the second tube wall 1021 are substantially on the same conical surface, and the connecting member 104 covers at least part of the first tube wall 1011 and at least part of the second tube wall 1021.

[0048] The first tube wall 1011 and the second tube wall 1021 are substantially on the same conical surface, which is convenient for partial fitting contact between the two tube walls and the connecting member 104. This part of the connecting member 104 is also arranged in a conical surface structure for convenient installation. When installing, the connecting member 104 is sleeved outside the two tube walls and then the connecting member 104 can be fixed to the disk body 100 by welding or other means. The first tube wall 1011 and the second tube wall 1021 being substantially on the same conical surface should be understood as that the first tube wall 1011 and the second tube wall 1021 visually form a conical shape as a whole, and there may be a certain angular offset or deviation of some structures.

[0049] Furthermore, the heating part of the first heating pipe 101 corresponds to the first groove part 107. The bottom and side wall of the heating part of the first heating pipe 101 are in contact with the first groove part 107 to minimize the dry burning of the heating part of the first heating pipe 101 and increase the effective utilization of its heating heat. Similarly, the heating part of the second heating pipe 102 corresponds to the second groove part 108. The first pipe wall 1011 and the second pipe wall 1021 are substantially on the same conical surface, so that on the basis that there is a position difference between the first heating pipe 101 and the second heating pipe 102 in the axial direction of the disc body 100, it is possible to ensure as much as possible the contact between the heating parts of the two heating pipes and the corresponding two groove parts, and minimize the dry burning of the heating parts of the two heating pipes, which is beneficial to improving the heating efficiency and heat utilization rate of the two heating pipes.

[0050] In one embodiment, the first heating pipe 101 includes a first main body part 1012, and the second heating pipe 102 includes a second main body part 1022. Both the first main body part 1012 and the second main body part 1022 are substantially in the shape of a circular arc segment. In the projection in the horizontal direction, the second main body part 1022 is located in the space surrounded by the first main body part 1012, and the first main body part 1012 surrounds the outer circle of the second main body part 1022.

[0051] The first main body part 1012 and the second main body part 1022 are used as the heating main bodies and are in a circular ring shape, so that the heating disc can uniformly heat the fluid and improve its heating efficiency.

[0052] Furthermore, the first heating pipe 101 has a first power connection part 1013, and the first power connection part 1013 is inclined upward relative to the circular ring structure where the first main body part 1012 is located. Specifically, when the first main body part 1012 is located in the first groove, the first power connection part 1013 is located outside the first groove, so as to facilitate the connection between the first power connection part 1013 and the conductive component. The conductive component can be a rigid conductive rod or a flexible wire. Similarly, the second heating pipe 102 has a second power connection part 1023, and the second power connection part 1023 is inclined upward relative to the circular ring structure where the second main body part 1022 is located. Specifically, when the second main body part 1022 is located in the second groove part 108, the second power connection part 1023 is located outside the second groove part 108, so as to facilitate the connection between the second power connection part 1023 and the conductive component.

[0053] Such as Figure 12As shown in the figure, an embodiment also discloses a heat pump, which includes a heating plate 1 and a pump body 2 installed on the heating plate 1. The pump body 2 has a pump chamber, and the heating plate 1 has a through-flow port 1003. The pump chamber is communicated with the through-flow port 1003. The heating plate 1 includes a plate body 100, a first heating tube 101, and a second heating tube 102. The plate body 100 has a heating channel 103. The first heating tube 101 surrounds a part of the channel wall of the heating channel 103, and the second heating tube 102 surrounds another part of the channel wall of the heating channel 103. The first heating tube 101 and the second heating tube 102 have a positional difference in the axial direction of the plate body 100.

[0054] The heat pump of this embodiment can be used in electrical appliances such as dishwashers and washing machines. On the one hand, the heat pump gives power to convey the fluid, and on the other hand, it heats the fluid flowing through its pump chamber, so that electrical appliances such as dishwashers or washing machines have better working efficiency at a certain temperature. Further, in an embodiment, the heating plate is located at the end of the pump body, and the fluid flows through the heating plate and enters the pump chamber, and then flows out. The first heating tube 101 and the second heating tube 102 have a positional difference in the axial direction of the plate body 100, so that the fluid has a relatively long heating path during the process of flowing through the heating plate, and the fluid is heated in a three-dimensional manner, increasing the heating efficiency of the fluid.

[0055] In this embodiment, the axial direction of the plate body 100 is the length direction of the heat pump. Since the first heating tube 101 and the second heating tube 102 have a positional difference in the axial direction of the plate body 100, the space of the pump chamber can be borrowed, so the radial size of the heat pump can be guaranteed to be miniaturized.

[0056] Further, the heating channel 103 includes a first heating channel 1031 and a second heating channel 1032, and the first heating channel 1031 is communicated with the second heating channel 1032. Define the channel side wall corresponding to the first heating channel 1031 as the first channel wall 10311, and define the channel side wall corresponding to the second heating channel 1032 as the second channel wall 10321. The first heating tube 101 surrounds at least part of the first channel wall 10311, and the second heating tube 102 surrounds at least part of the second channel wall 10321; the two heating tubes can respectively heat the fluid in the first heating channel 1031 and the second heating channel 1032.

[0057] The fluid flows through the first heating channel 1031 and the second heating channel 1032 from the through-flow port 1003, then enters the pump chamber, and then flows out of the pump chamber; the two heating channels make the fluid have a relatively long heating path, and the fluid can be heated in a three-dimensional manner when flowing through the heat pump, increasing the heating efficiency of the heat pump for the fluid.

[0058] The above are only typical specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes to obtain technical solutions, concepts, and designs, which should all be covered within the protection scope of the present utility model.
