Description

Technical Field

[0001] This invention relates to the field of household appliance technology, and in particular to a heat pump and a dishwasher. Background Technology

[0002] With the rapid development of technology, automated home appliances have more functions to better serve people's lives. For example, automatic dishwashers can heat the liquid inside the pump body while driving water flow, thus making it easier to wash dishes and providing convenience for people's lives.

[0003] In existing technologies, most heating pumps have heating tubes that are bent into a circle and embedded in the top or side of the pump casing. In this case, the heating tubes need to be bent along the pump casing, which increases the difficulty of the manufacturing process and increases the risk that the heating tubes may not be fully embedded in the pump casing due to insufficient roundness. This can easily increase safety hazards and reduce the service life of the heating pump. Summary of the Invention

Two first heating sections are arranged side by side and are respectively connected to two terminals. Multiple second heating sections are arranged side by side. The connecting section is used for two adjacent second heating sections or adjacent first heating sections and second heating sections.

[0015] The extension direction of each of the first heating sections is parallel to the extension direction of each of the second heating sections.

[0016] In one embodiment, the heating tube includes a first heating section, a second heating section, and a connecting section. Two first heating sections are arranged side by side and are respectively connected to two terminals. Multiple second heating sections are arranged side by side. The connecting section is used for two adjacent second heating sections or adjacent first heating sections and second heating sections.

[0017] The extension direction of each of the first heating sections is perpendicular to the extension direction of each of the second heating sections.

[0018] In one embodiment, at least one of the mounting portion and the connecting portion is detachably connected to the pump housing.

[0019] In one embodiment, a first connecting structure is provided between the mounting part and the pump housing. The first connecting structure includes a matching fastener and a snap-fit ​​hole. One of the mounting part and the pump housing is provided with the fastener, and the other is provided with the snap-fit ​​hole.

[0020] And / or, a second connection structure is provided between the connecting part and the pump housing, the second connection structure including a first connection hole and a second connection hole respectively provided in the connecting part and the pump housing, and a fastener connecting the first connection hole and the second connection hole in series.

[0047] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0048] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0049] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0050] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or" or "and / or" throughout the text includes three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0051] With the rapid development of technology, automated home appliances have more functions to better serve people's lives. For example, automatic dishwashers can heat the liquid inside the pump body while driving water flow, thus making it easier to wash dishes and providing convenience for people's lives.

[0052] In existing technologies, most heating pumps have heating tubes that are bent into a circle and embedded in the top or side of the pump casing. In this case, the heating tubes need to be bent along the pump casing, which increases the difficulty of the manufacturing process and increases the risk that the heating tubes may not be fully embedded in the pump casing due to insufficient roundness. This can easily increase safety hazards and reduce the service life of the heating pump.

[0053] To solve this technical problem, the present invention proposes a heating pump 1.

[0054] Please see Figures 1 to 14In one embodiment of the present invention, the heat pump 1 includes a pump housing 11 and a heating component 20; the heating component 20 is disposed on one side of the pump housing 11, and the heating component 20 includes a mounting shell 21 and a heating tube 22. The mounting shell 21 is connected to the pump housing 11, and the heating tube 22 is bent and disposed on a plane and embedded in the mounting shell 21; thereby reducing the processing difficulty of the heat pump 1, reducing the defect rate in the production process, and thus improving the safety and service life of the heat pump 1.

[0055] In the technical solution of the present invention, the heating component 20 is fixed to one side of the pump housing 11 by the mounting shell 21, and the heating tube 22 located in the mounting shell 21 is bent on the plane, which can effectively avoid the situation that some heating tubes 22 are not embedded in the pump housing 11 due to poor roundness of the bending of the heating tube 22, and are easily corroded. Furthermore, by bending the heating tube 22 on the plane, the manufacturing difficulty of the heating component 20 is reduced, thereby reducing the defect rate in the production process and improving the safety and service life of the heating pump 1.

[0056] Specifically, the pump housing 11 and the heating component 20 can be integrated, for example, by welding or casting, to form a single unit. Alternatively, they can be detached, for example, by screw connection, snap-fit ​​connection, or pin fixing, to facilitate after-sales maintenance and replacement of heating components 20 with different power ratings, thereby improving user satisfaction.

[0057] Embedding the heating tube 22, which is bent into a plane, into the mounting housing 21 simplifies the manufacturing process compared to bending the heating tube 22 around the pump housing 11. For example, it reduces the need to use specialized tools to ensure the concentricity of the pump housing 11 and the heating tube 22.

[0058] Optionally, the heating pump 1 includes a pump housing 11 and a bottom cover 12, which are connected to form a pump chamber 101. The pump chamber 101 has a connected inlet 102 and an outlet 103, ensuring that cold water flowing into the pump chamber 101 from the inlet 102 is turned into hot water under the action of the heating component 20 and flows out from the outlet 103.

[0059] The heating pump 1 also includes an impeller 13 built into the pump chamber 101 and a motor 14 driven by the impeller 13. The motor 14 is located below the bottom cover 12, and the drive shaft 141 of the motor 14 passes through the bottom cover 12 and extends into the pump chamber 101, and is connected to the impeller 13. Thus, when the heating component 20 transmits the heat generated along the mounting shell 21 and the pump shell 11 into the pump chamber 101 to change the temperature of the cold water, the motor 14 is turned on, and the drive shaft 141 of the motor 14 drives the impeller 13 to rotate, which converts the low-pressure liquid entering from the inlet 102 into high-pressure liquid and discharges it from the outlet 103. The high-pressure liquid is hot water, which is used to pump hot water to equipment that needs hot water, such as a dishwasher, to improve the overall performance of the equipment.

[0060] Alternatively, a motor bracket 15 may be provided below the pump housing 11. The motor bracket 15 and the bottom cover 12 form an installation space for accommodating the motor 14. The motor bracket 15 can be connected to the pump housing 11 via multiple adapter legs arranged circumferentially to create this installation space. This reduces the weight of the motor bracket 15 and ensures the motor 14 is securely mounted on the heating pump 1. The connection between the motor bracket 15 and the pump housing 11 includes, but is not limited to, snap-fit ​​connections and pin engagements, facilitating rapid assembly of the pump housing 11 and the motor bracket 15.

[0061] Please see Figure 3 In an embodiment of the present invention, the mounting shell 21 includes a mounting portion 211 and a connecting portion 212. The mounting portion 211 is adapted to be mounted on the side of the pump shell 11 and has the heating tube 22 embedded therein. The connecting portion 212 is located on the side of the mounting portion 211 facing the pump shell 11 and overlaps with the top of the pump shell 11. It can be understood that the mounting shell 21 is mounted on one side of the pump shell 11 via the connecting portion 212, and the connecting portion 212 fits against the top of the pump shell 11, which can, to a certain extent... The mounting housing 21 is supported by the upper part, which increases the contact area between the mounting housing 21 and the pump housing 11, thereby improving the connection stability between the mounting housing 21 and the pump housing 11. Furthermore, because the connecting part 212 is laterally connected to the side of the mounting part 211 facing the pump housing 11, the top surface of the mounting part 211 can be slightly higher than the top surface of the pump housing 11. This increases the space for the heating tube 22, extends the length of the heating tube 22, improves the thermal efficiency of the heating tube 22 and its arrangement within the mounting housing 21, and thus improves the heating efficiency of the heat pump 1. However, in other embodiments, the mounting housing 21 only includes the mounting part 211, and the mounting housing 21 is connected to the pump housing 11 through the mounting part 211.

[0062] The mounting part 211 and the connecting part 212 can be manufactured by integral casting, which facilitates efficient wrapping of the heating tube 22 and allows the heating assembly 20 to be fixed as a whole on the pump housing 11, improving the forming or assembly efficiency of the heat pump 1. The mounting housing 21 can be a cast aluminum housing, meaning it is formed using a cast aluminum process. The manufacturing material includes aluminum, allowing for a lightweight design and good thermal conductivity, enabling efficient transfer of heat generated by the heating tube 22 to the pump housing 11. Alternatively, the pump housing 11 can also be configured as a cast aluminum housing to efficiently receive the heat transferred from the mounting housing 21 to the pump housing 11, using this heat as a heat source for the cold water inside the pump housing 11, thus heating the cold water, reducing heat loss, and improving the heating efficiency of the heat pump 1.

[0063] Furthermore, in an embodiment of the present invention, a heat-conducting layer is provided between the mounting shell 21 and the pump shell 11. Specifically, a molded heat-conducting layer, such as thermally conductive silicone, is applied to the contact surfaces of the mounting shell 21 and the pump shell 11. These contact surfaces specifically include the inner surface of the mounting shell 21 facing the pump shell 11, the side surface of the pump shell 11 that fits against the mounting portion 211, and the top surface of the pump shell 11 that fits against the connecting portion 212. This allows heat to be transferred more smoothly to the pump shell 11, improving heat transfer efficiency. Of course, in other embodiments, no heat-conducting layer is provided between the mounting shell 21 and the pump shell 11. The heat-conducting layer can be made of silicone, rubber, or other metals or inorganic materials with good thermal conductivity.

[0064] Optionally, in an embodiment of the present invention, the mounting portion 211 has a first surface 2111 and a second surface 2112 disposed opposite to each other. The first surface 2111 is in contact with the side surface of the pump housing 11, and the heating tube 22 is located between the first surface 2111 and the second surface 2112 to ensure that the heating tube 22 is completely covered within the mounting portion 211, avoiding the heating tube 22 being exposed outside the mounting housing 21, reliably reducing the risk of corrosion of the heating tube 22, extending the service life of the heating tube 22, and reducing safety hazards.

[0065] Please see Figure 3 and Figure 12In an embodiment of the present invention, the side surface of the pump housing 11 is an arc surface, the first surface 2111 is an arc surface that fits against the side surface of the pump housing 11, and the second surface 2112 is a vertical surface extending along the vertical direction of the pump housing 11. The plane where the heating tube 22 is located is parallel to the second surface 2112. It can be understood that, in order to avoid increasing the risk of the heating tube 22 leaking out of the mounting shell 21, the first surface 2111 has a cross-section parallel to the second surface 2112. At this time, the heating tube 22 is located between the cross-section and the second surface 2112, reliably ensuring the wrapping effect of the mounting part 211 on the heating tube 22. Further, the plane where the heating tube 22 is located is parallel to the second surface 2112, that is, the heating tube 22 is placed vertically. Here, the heating tube 22 can be placed close to the cross-section, which shortens the heat transfer path and helps to ensure the uniformity of heat transfer to the pump housing 11, reducing the occurrence of overheating or overcooling on the pump housing 11. However, in other embodiments, the plane where the heating tube 22 is located intersects with the second surface 2112.

[0066] Please see Figure 2 In an embodiment of the present invention, the top of the pump housing 11 is provided with a water inlet 111, and the connecting part 212 is provided with a snap 2121 adapted to the outer wall of the water inlet 111. At this time, the water inlet 102 is formed in the water inlet 111, and the side of the pump housing 11 is also provided with a water outlet, and a water outlet 103 is formed in the water outlet. Since the connecting part 212 is mounted on the top of the pump housing 11 and is located close to the water inlet 111, by providing a snap 2121 in the connecting part 212, the snap 2121 of the connecting part 212 can be used to snap with the outer wall of the water inlet 111, reducing the interference between the connecting part 212 and the water inlet 111. It can also work with the side surface of the pump housing 11 to constrain the assembly position of the mounting shell 21, and facilitate the subsequent fixation of the mounting shell 21 and the pump housing 11 by the first connecting structure 23 and / or the second connecting structure 24.

[0067] Please see Figure 11 In an embodiment of the present invention, the mounting shell 21 further includes an auxiliary mounting portion 213, which is located at least above the mounting portion 211 to assist in accommodating the heating tube 22. Thus, by increasing the volume of the mounting shell 21, the space available for the heating tube 22 to be installed is increased, thereby facilitating the extension of the length of the heating tube 22, improving the thermal efficiency of the heating tube 22 and its arrangement within the mounting shell 21, thereby improving the heating efficiency of the heating pump 1.

[0068] The auxiliary mounting portion 213 may also be located above the connecting portion 212. When the auxiliary mounting portion 213 extends toward the connecting portion 212, a clearance groove 2131 corresponding to the second connecting structure 24 may be provided on the auxiliary mounting portion 213 to ensure a reliable connection between the second connecting structure 24 and the mounting housing 21 and the pump housing 11. However, in other embodiments, the auxiliary mounting portion 213 may be located below the mounting portion 211. The auxiliary mounting portion 213 may also be used to assist in the installation of the protector 25 connected to the heating tube 22. For example, when the terminals 221 of the protector 25 and the heating tube 22 are both located on the side of the mounting housing 21, the side of the auxiliary mounting portion 213 may provide a mounting surface for the protector 25. However, in other embodiments, the mounting housing 21 does not include the auxiliary mounting portion 213.

[0069] Optionally, in an embodiment of the present invention, the heating tube 22 has two terminals 221, which extend from the top or side of the mounting portion 211, facilitating the connection of the heating tube 22 to the control circuit via the terminals 221 to control the heating tube 22. Whether the terminals 221 extend from the top or side of the mounting portion 211 can be selected based on the specific bending of the heating tube 22 within the mounting portion 211, the length of the heating tube 22 within the mounting portion 211, and the available space outside the mounting portion 211 for electrical devices connected to the heating tube 22.

[0070] Please see Figure 8 and Figure 13 In an embodiment of the present invention, the heating tube 22 includes a first heating section 222, a second heating section 223, and a connecting section 224. Two first heating sections 222 are arranged side by side and are respectively connected to two terminals 221. Multiple second heating sections 223 are arranged side by side. The connecting section 224 is used for two adjacent second heating sections 223 or adjacent first heating sections 222 and second heating sections 223. This allows the heating tube 22 to have a longer length in a limited space, which helps to improve the thermal efficiency of the heating tube 22 and also makes the thermal uniformity of the plane where the heating tube 22 is located better, facilitating the transfer of heat to the pump housing 11 and heating the water in the pump chamber.

[0071] The extending direction of each of the first heating sections 222 is parallel to the extending direction of each of the second heating sections 223. It can be understood that the heating tube 22 is continuously bent within the mounting housing 21 to form multiple rows of heating sections, thereby fully utilizing the space within the mounting housing 21. The number of rows of heating sections includes, but is not limited to, 2, 3, and 4, and can be increased or decreased according to actual needs; this is not limited here. Figure 8As shown, the first heating section 222 extends along the vertical direction of the heating pump 1, so that the terminal 221 connected to the first heating section 222 can extend out of the top of the mounting part 211. The terminal 221 can extend partially or completely out of the top of the mounting part 211 to raise the terminal 221, which facilitates the connection of the terminal to electrical devices such as the temperature protector 25. Since the extension direction of each second heating section 223 is parallel to the extension direction of the first heating section 222, the second heating section 223 extends along the vertical direction of the heating pump 1, and adjacent first heating sections 222 and second heating sections 223, as well as two adjacent second heating sections 223, are connected by a connecting section 224 to ensure the continuous bending of the heating tube 22.

[0072] like Figure 13 As shown, the first heating section 222 extends horizontally along the heating pump 1, so that the terminal 221 connected to the first heating section 222 can extend out of the side of the mounting part 211. The terminal 221 can extend partially or completely out of the top of the mounting part 211 to raise the terminal 221, which facilitates the connection of the terminal to electrical devices such as temperature protector 25. Since the extension direction of each second heating section 223 is parallel to the extension direction of the first heating section 222, the second heating section 223 extends horizontally along the heating pump 1, and adjacent first heating sections 222 and second heating sections 223, as well as two adjacent second heating sections 223, are connected by connecting sections 224 to ensure the continuous bending of the heating tube 22.

[0073] Please see Figure 5 In an embodiment of the present invention, the heating tube 22 includes a first heating section 222, a second heating section 223, and a connecting section 224. Two first heating sections 222 are arranged side by side and are respectively connected to two terminals 221. Multiple second heating sections 223 are arranged side by side. The connecting section 224 is used for two adjacent second heating sections 223 or adjacent first heating sections 222 and second heating sections 223. This allows the heating tube 22 to have a longer length in a limited space, which helps to improve the thermal efficiency of the heating tube 22 and also makes the thermal uniformity of the plane where the heating tube 22 is located better, facilitating the transfer of heat to the pump housing 11 and heating the water in the pump chamber.

[0074] The extending direction of each of the first heating sections 222 is perpendicular to the extending direction of each of the second heating sections 223. It can be understood that the heating tube 22 is continuously bent within the mounting housing 21 to form multiple rows of heating sections, thereby fully utilizing the space within the mounting housing 21. The number of rows of heating sections includes, but is not limited to, 2, 3, and 4, and can be increased or decreased according to actual needs; this is not limited here. Figure 5As shown, the first heating section 222 extends vertically along the heating pump 1, allowing the terminal 221 connected to the first heating section 222 to extend beyond the top of the mounting portion 211. The terminal 221 can extend partially or completely beyond the top of the mounting portion 211 to elevate it, facilitating connection to electrical devices such as a temperature protector 25. Since the extension direction of each second heating section 223 is perpendicular to the extension direction of the first heating section 222, and the second heating section 223 extends horizontally along the heating pump 1, adjacent first heating sections 222 and second heating sections 223, as well as two adjacent second heating sections 223, are connected by a connecting section 224, ensuring continuous bending of the heating tube 22. Of course, in other embodiments, based on the fact that the extension direction of each first heating section 222 is perpendicular to the extension direction of each second heating section 223, the terminal 221 connected to the first heating section 222 can extend beyond the side of the mounting portion 211.

[0075] Please see Figures 1 to 3 , Figure 12 In an embodiment of the present invention, at least one of the mounting part 211 and the connecting part 212 is detachably connected to the pump housing 11. This configuration enables flexible assembly of the heating pump 1, that is, the heating component 20 and the pump housing 11 are connected by a detachable connection, which facilitates after-sales maintenance and also allows for flexible replacement of heating components 20 with different power, thereby improving user satisfaction.

[0076] Furthermore, when the mounting part 211 and the connecting part 212 are connected to the pump housing 11 at the same time, the connection stability between the heating component 20 and the pump housing 11 can be improved to a certain extent, so that the heating component 20 can reliably heat the water in the pump chamber and meet the user's needs.

[0077] Specifically, in one embodiment of the present invention, a first connecting structure 23 is provided between the mounting part 211 and the pump housing 11. The first connecting structure 23 includes a matching fastener 231 and a fastening hole 232. One of the mounting part 211 and the pump housing 11 is provided with the fastener 231, and the other is provided with the fastening hole 232. Figure 2 and Figure 3 As shown, a fastener 231 is provided on the side surface of the pump housing 11. The fastener 231 includes a support section and a fastening section connected above the support section. The bottom of the mounting part 211 is provided with a fastening hole 232, and the opening of the fastening hole 232 faces downward. An avoidance slot 2121 is formed on the first surface 2111 of the mounting part 211. After the fastening section extends into the fastening hole 232, the avoidance slot 2121 engages with the support section to limit the fastening. This allows the fastener 231 to be tightly spliced ​​with the mounting part 211, thereby effectively ensuring that the first surface 2111 is tightly attached to the side surface of the pump housing 11, thus ensuring the heat transfer efficiency of the heating pump 1.

[0078] Specifically, in another embodiment of the present invention, a second connecting structure 24 is provided between the connecting part 212 and the pump housing 11. The second connecting structure 24 includes a first connecting hole 241 and a second connecting hole 242 respectively provided in the connecting part 212 and the pump housing 11, and a fastener 243 connecting the first connecting hole 241 and the second connecting hole 242 in series. The fastener 243 can be a screw or a pin. When the fastener 243 is a screw and is inserted into the first connecting hole 241 and the second connecting hole 242 from top to bottom, the second connecting hole 242 is a threaded hole to cooperate with the external thread of the screw, thereby completing the connection and fixation of the fastener 243 to the connecting part 212 and the pump housing 11. In this process, the first connecting hole 241 can be a threaded hole or a through hole. However, in other embodiments, a positioning post is provided on the pump housing 11. The positioning post has an internal thread, and the connecting part 212 has a positioning hole for the positioning post to pass through. The screw is inserted into the positioning post, and its head or a washer presses against the edge of the positioning hole.

[0079] Specifically, in another embodiment of the present invention, a first connecting structure 23 is provided between the mounting part 211 and the pump housing 11. The first connecting structure 23 includes a fastener 231 and a fastening hole 232 that cooperate with each other. One of the mounting part 211 and the pump housing 11 is provided with the fastener 231, and the other is provided with the fastening hole 232. A second connecting structure 24 is provided between the connecting part 212 and the pump housing 11. The second connecting structure 24 includes a first connecting hole 241 and a second connecting hole 242 respectively provided in the connecting part 212 and the pump housing 11, and a fastener 243 connecting the first connecting hole 241 and the second connecting hole 242 in series. In this way, by the different positions of the first connecting structure 23 and the second connecting structure 24, the stable assembly between the pump housing 11 and the mounting housing 21 can be ensured on the basis of reasonably dispersing the forces between the structures.

[0080] Please see Figure 1 , Figure 11 In an embodiment of the present invention, the heat pump 1 further includes a protector 25 disposed on the mounting housing 21. The protector 25 is connected to the terminal 221 of the heating tube 22 via a conductive rod 26. Thus, when the temperature is too high, the protector 25 can quickly disconnect the heating of the heating tube 22, thereby enabling the heat pump 1 to have a power-off protection function, effectively eliminating safety hazards and improving the safety of the heat pump 1. Specifically, the protector 25 has two terminals 221 corresponding to each other, and the conductive rod 26 connects the corresponding terminals 221 to complete the electrical connection of the heating tube 22 in the control circuit. The conductive rod 26 acts as a power line connecting the terminal of the protector 25 and the terminal 221 of the heating tube 22.

[0081] When the terminal 221 extends out of the top of the mounting housing 21, the protector 25 is fixed to the top of the mounting housing 21 and is located close to the terminal 221. When the terminal 221 extends out of the side of the mounting housing 21, the protector 25 is fixed to the side of the mounting housing 21 and is located close to the terminal 221. The installation method of the protector 25 includes, but is not limited to, welding, riveting, and screw connection.
