Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0031] A heat pump water heater is a device that uses the heat pump principle to produce hot water. It absorbs heat from the air or other low-temperature heat sources, compresses it through a compressor to generate heat, and then exchanges heat with water, thereby improving thermal efficiency.

[0032] The existing heat pump water heater unit has a compact structure design. In order to save space to the greatest extent and reduce the cost of raw materials while ensuring the performance of the unit, the unit's electrical control box is generally placed on the upper right side of the unit, and is supported and fixed by a sheet metal partition in the middle of the unit.

[0033] During the installation and fixing process of the electric control box components, the operator needs to place the electric control box components on the middle partition for installation. However, the electric control box components are very easy to fall over on the middle partition, which affects the efficiency of installation and fixing.

[0034] In order to solve the above problems, the heat pump water heater provided in the present application provides a clamping portion on the first electric control box. During the installation process, the middle partition and the motor bracket are first installed in the shell. After the internal devices in the heat pump water heater are installed, the middle part of the first electric control box is placed on the top of the middle partition, and the clamping portion is clamped with the motor bracket, so that the first electric control box has two-point support, avoiding the possibility of the first electric control box tipping over when placed alone on the middle partition; at the same time, after the clamping portion is clamped with the motor bracket, it plays a role in positioning the first electric control box, avoiding the need to readjust the position when using fixings to fix the first electric control box, thereby further improving the efficiency of installation.

[0035] The following specific embodiments describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems. The following specific embodiments can exist independently or in combination with each other. For the same or similar concepts or processes, they may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0036] This application provides a heat pump water heater, referring to Figures 1 to 6 , the heat pump water heater includes a housing 100, a first electric control box 200, a middle partition 300, a motor bracket 400 and fixing parts;

[0037] The middle partition 300 is arranged in the shell 100, the motor bracket 400 is arranged on the top of the shell 100, and the first electric control box 200 is provided with a clamping portion 500, which is clamped with the motor bracket 400 and / or the shell 100. The first electric control box 200 is placed on the top of the middle partition 300, and the fixing part is arranged on the middle partition 300 for fixing the first electric control box 200 on the middle partition 300.

[0038] In order to save space, the electric control box is installed above the shell 100. The clamping portion 500 can be clamped to the shell 100, the motor bracket 400, or the shell 100 and the motor bracket 400 at the same time. In this application, the clamping portion 500 and the motor bracket 400 are taken as an example. In the prior art, the heat pump water heater also includes structures such as a heat exchanger, fan blades and a compressor assembly. Among them, the heat exchanger adopts an L-shaped fin heat exchanger. And the shell 100 includes a base and a circumferential cover. Among them, the first electric control box 200 is used to install the control elements, circuit boards and other electrical components of the heat exchanger. The first electric control box 200 provides an installation position for the internal electrical components and plays a protective role.

[0039] During the installation process, the heat exchanger is installed on the base, the motor bracket 400 is installed on the top of the heat exchanger, and then the fan blades are installed on the heat exchanger, and then the middle partition 300 is installed. The middle partition 300 divides the shell 100 into two parts, where the heat exchanger and the fan blades are located on the same side of the middle partition 300, and the compressor assembly is installed on the other side of the middle partition 300. Then, the middle part of the first electrical control box 200 is placed on the top of the middle partition 300, and the clamping part 500 is clamped with the motor bracket 400 to achieve the initial positioning and fixation of the first electrical control box 200. Then, the first electrical control box 200 is fixed to the middle partition 300 through the fixing parts. Finally, the cover body is placed on the base and the corresponding position is fixed with bolts. The first electric control box 200 has two points of support during the initial installation process, which avoids the possibility of the first electric control box 200 tipping over when placed alone on the middle partition 300; at the same time, after the clamping portion 500 is clamped with the motor bracket 400, it plays a positioning role for the first electric control box 200, avoiding the need to readjust the position when fixing the first electric control box 200 with fixing parts, further improving the efficiency of installation.

[0040] Illustratively, the fixing member is a bolt or a screw, which passes through the middle partition plate 300 and is threadedly connected to the first electric control box 200 to fix the first electric control box 200 on the middle partition plate 300 .

[0041] In some embodiments, reference Figure 2 and Figure 3The distance between the end of the first electric control box 200 close to the motor bracket 400 and the middle partition 300 is smaller than the distance between the end of the first electric control box 200 far from the motor bracket 400 and the middle partition 300.

[0042] And, refer to Figure 3 and Figure 4 The clamping part 500 includes a first connecting plate 510, a second connecting plate 520 and a limiting plate 530 connected in sequence. The first connecting plate 510 is arranged on the first electric control box 200, the second connecting plate 520 is located at the bottom of the motor bracket 400, and the limiting plate 530 extends into the motor bracket 400 and abuts against the inner wall of the motor bracket 400.

[0043] In the embodiment of the present application, when the first electric control box 200 is placed on the middle partition 300, the weight of the first electric control box 200 at the end close to the motor bracket 400 is less than the weight of the first electric control box 200 at the end away from the motor bracket 400, so that when the first electric control box 200 is placed on the middle partition 300, the first electric control box 200 has a tendency to tilt toward the direction away from the motor bracket 400. After the second connecting plate 520 extends to the bottom of the motor bracket 400, it abuts against the bottom of the motor bracket 400 to block the tilting of the first electric control box 200 through the motor bracket 400, and the limiting plate 530 extends into the motor bracket 400. When the motor bracket 400 abuts against the limiting portion 310, the first electric control box 200 is positioned to facilitate the clamping and positioning between the clamping portion 500 and the motor bracket 400.

[0044] Furthermore, a hole is formed on the second connecting plate 520 so as to fix the second connecting plate 520 to the bottom of the motor bracket 400 using bolts, thereby further improving the stability of the connection of the first electric control box 200 .

[0045] In some embodiments, reference Figure 2 and Figure 3 A mounting plate 210 is provided on the first electric control box 200 . The mounting plate 210 is located at one end away from the clamping portion 500 . A first edge portion 211 is provided around the mounting plate 210 . The first edge portion 211 is used to connect with the housing 100 .

[0046] The mounting plate 210 is parallel to the middle partition 300 and is bolted to the bottom of the first electrical control box 200. A control switch, a power cord connector, and other structures are mounted on the mounting plate 210 to provide a connection port for the power cord. A first edge portion 211 disposed circumferentially around the mounting plate 210 forms a cavity with the mounting plate 210, providing space for placement of the control switch, power cord connector, and other structures. Furthermore, the first edge portion 211 is bolted to the housing 100 to further enhance the stability of the connection to the first electrical control box 200.

[0047] In some embodiments, reference Figure 2 and Figure 5 A transition plate 212 is provided at the bottom of the mounting plate 210 , and the bottom of the transition plate 212 is inclined toward a side away from the middle partition plate 300 .

[0048] A transition plate 212 is angled at the bottom of the mounting plate 210. The power cord is placed on the transition plate 212 and then connected to the power cord connector structure on the mounting plate 210. This allows the power cord to smoothly transition along the inclined surface of the transition plate 212 to the outside of the water heater, reducing the risk of bending and damage to the power cord, thereby reducing leakage and improving safety. Furthermore, the installation of the mounting plate 210 increases the weight of the end of the first electrical control box 200, facilitating the connection between the clamping portion 500 and the motor bracket 400.

[0049] In some embodiments, a limiting portion 310 is provided on the top of the middle partition 300 , and the limiting portion 310 abuts against the first electric control box 200 .

[0050] The stopper 310 is located at the top of the middle partition 300, away from the heat exchanger. The stopper 310 and the top of the middle partition 300 form an L-shape. When the first electrical box 200 is placed on the middle partition 300, the bottom of the first electrical box 200 connects to the top of the middle partition 300, and the sides of the first electrical box 200 respectively abut the heat exchanger and the stopper 310, thereby improving the stability of the connection of the first electrical box 200.

[0051] Furthermore, the limiting portion 310 is provided with a hole, so that a bolt can pass through the limiting portion 310 to be threadedly connected to the first electric control box 200 , thereby further improving the stability of the connection of the first electric control box 200 .

[0052] In some embodiments, reference Figure 2 and Figure 6 A plurality of connecting parts 320 are provided on the top of the middle partition 300 , and fixing members are provided on the connecting parts 320 to be connected with the first electric control box 200 , and ventilation slots 330 for ventilation are formed between adjacent connecting parts 320 .

[0053] Exemplarily, two connecting portions 320 are provided, one on each side of the top of the middle partition 300 and protruding from the top of the middle partition 300. The connecting portions 320 are integrally formed with the middle partition 300. A ventilation slot 330 is formed between the two connecting portions 320. The connecting portions 320 are provided with a second edge portion with a recessed portion to allow a fixing member to pass through the second edge portion and threadably connect to the first electrical control box 200, thereby securing the first electrical control box 200 to the middle partition 300.

[0054] The ventilation slots 330 formed at the bottom of the middle partition 300 reduce the contact area between the middle partition 300 and the first electrical control box 200, and at the same time form a ventilation channel connecting the two sides of the middle partition 300, so as to improve the heat dissipation effect at the bottom of the first electrical control box 200 and reduce the possibility of overheating of the internal components of the first electrical control box 200.

[0055] In some embodiments, reference Figure 1 and Figure 2 The heat pump water heater further includes a second electric control box 600 , which is disposed on the motor bracket 400 . The second electric control box 600 is located on a side of the motor bracket 400 away from the first electric control box 200 , and is connected to the housing 100 .

[0056] The second electrical control box 600 is also used to house the heat exchanger's control elements, circuit boards, and other electrical components. Specifically, the existing circuit components are installed separately in the first and second electrical control boxes 200 and 600. The original electrical control box is split into the first and second electrical control boxes 200 and 600 to increase the space within the electrical control box. This maximizes the structural space within the existing unit dimensions, ensuring the placement of relevant components within the electrical control box and the performance of its related functions. The newly added second electrical control box 600 is spaced slightly apart from the heat exchanger, both horizontally and vertically. When the impellers rotate, the second electrical control box 600 provides limited obstruction to the heat exchanger, effectively ensuring the heat exchange efficiency of the heat exchanger.

[0057] The provision of the second electrical control box 600 does not affect the operation of the heat exchanger while effectively utilizing the existing size of the unit. That is, it enhances the versatility of the unit while ensuring the performance of the unit. It also enables the addition of electrical control components to the unit without increasing the size of the unit, thereby facilitating functional upgrades of the unit.

[0058] In some embodiments, a first fixing plate 610 is provided on the second electric control box 600 . The first fixing plate 610 extends onto the motor bracket 400 and is connected to the motor bracket 400 .

[0059] The first fixing plate 610 is a Z-shaped plate. One end of the first fixing plate 610 is fixed to the second electric control box 600 by bolts, and the other end is placed on the motor bracket 400 and fixed by bolts to achieve the connection and fixation between the first electric control box 200 and the motor bracket 400.

[0060] In some embodiments, a second fixing plate 620 is provided on the second electric control box 600 . The second fixing plate 620 extends onto the housing 100 and is connected to the housing 100 .

[0061] The second fixing plate 620 is a Z-shaped plate identical to the first fixing plate 610. One end of the second fixing plate 620 is fixed to the second electrical control box 600, and the other end is placed on the housing 100 to limit the second electrical control box 600 and position the second electrical control box 600. The second fixing plate 620 is fixed to the housing 100 by bolts.

[0062] Furthermore, a third fixing plate is provided on the second electric control box 600 for connecting with the cover, thereby further improving the stability of the connection of the second electric control box 600.

[0063] The heat pump water heater provided in the present application is provided with a clamping portion 500 on the first electric control box 200. During the installation process, the middle partition 300 and the motor bracket 400 are first installed in the shell 100. After the internal devices in the heat pump water heater are installed, the middle part of the first electric control box 200 is placed on the top of the middle partition 300, and the clamping portion 500 is clamped with the motor bracket 400, so that the first electric control box 200 has two-point support, avoiding the possibility of the first electric control box 200 being placed alone on the middle partition 300 and tipping over; at the same time, after the clamping portion 500 is clamped with the motor bracket 400, it plays a role in positioning the first electric control box 200, avoiding the need to readjust the position when fixing the first electric control box 200 with fixing parts, thereby further improving the efficiency of installation.
