[0040] In the description of the embodiments of the present application, it should be noted that the terms "first direction" and "second direction" are based on the attached Figure 8 The orientation or position relationship shown in the figure is based on the Figure 9 These directional terms are only used to facilitate the description of the embodiments of the present application and to simplify the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as limiting the embodiments of the present application.

[0041] The present application embodiment provides a head assembly, see Figures 1 to 3 、 Figure 5 The machine head assembly comprises an electric control box 10, a water pan 20, a cover 30 and a heat exchanger 40.

[0042] The cover 30 is arranged on one side of the water pan 20, and the cover 30 has an air inlet 30a and an air outlet 30b.

[0043] The heat exchanger 40 is arranged in the cover 30, and the heat exchanger 40 divides the cover 30 into a first space 30c communicated with the air inlet 30a and a second space 30d communicated with the air outlet 30b.

[0044] The air inlet 30a is an entrance for external air flow into the cover 30, and the air outlet 30b is an exit for air flow out of the cover 30.

[0045] In addition to the electric control box 10 and the heat exchanger 40, the cover 30 also has components such as a compressor and a fan assembly. When the fan assembly works, the external air flow enters the first space 30c from the air inlet 30a, exchanges heat with the heat exchanger 40, and then flows out from the air outlet 30b through the second space 30d.

[0046] Please refer to Figure 1 、 Figures 8 to 11 The electric control box 10 of the embodiment comprises a box body assembly 11, an electric control board 12 and a waterproof assembly 13.

[0047] The box body assembly 11 comprises a first box body 111 and a second box body 112 which are openably and closably connected, the first box body 111 and the second box body 112 jointly define a containing cavity 11a and a wire passing opening 11b communicated with the containing cavity 11a, and a joint 11c is formed between the first box body 111 and the second box body 112 on the peripheral side of the box body assembly 11. The box body assembly 11 has a first side X1 and a second side X2 opposite to each other along a first direction, and a third side X3 and a fourth side X4 opposite to each other along a second direction, the second box body 112 is located on one side of the first box body 111 along a third direction, the wire passing opening 11b is located on the first side X1 of the box body assembly 11, and the first direction, the second direction and the third direction are three directions perpendicular to each other of the box body assembly 11.

[0048] The first box body 111 and the second box body 112 are openably and closably connected, that is, the first box body 111 and the second box body 112 can be opened or closed.

[0049] The electric control board 12 is arranged in the containing cavity 11a, and an element face 12a of the electric control board 12 faces the first box body 111, that is, the element face 12a of the electric control board can be maintained by opening the first box body 111.

[0050] The containing cavity 11a is used for containing the electric control board 12. The wire passing opening 11b is used for wire passing.

[0051] The joint 11c refers to a gap formed at the joint of the first box body 111 and the second box body 112 when the two are closed, and liquid such as rainwater and condensed water can easily flow into the accommodation cavity 11a of the electric control box 10 from the joint 11c, thereby causing the electric control board 12 to malfunction.

[0052] Referring to Figure 1 , Figure 5 and Figure 8 , the electric control box 10 is arranged in the first space 30c, the fourth side X4 of the box body assembly 11 faces the water pan 20, and the first side X1 of the box body assembly 11 is closer to the heat exchanger 40 than the second side X2. That is, the third side X3 of the box body assembly 11 is located on the side of the box body assembly 11 away from the water pan 20, and the distance between the first side X1 of the box body assembly 11 provided with the wire port 11b and the heat exchanger 40 is closer than the distance between the second side X2 of the box body assembly 11 and the heat exchanger 40, so that the wire port 11b of the box body assembly 11 can better avoid the air inlet 30a.

[0053] Referring to Figures 7 to 11 , the waterproof assembly 13 is arranged outside the box body assembly 11, and the waterproof assembly 13 includes a waterproof cover 131 arranged at least on one of the second side X2 and the third side X3 of the box body assembly 11, and the waterproof cover 131 is located on the side of the joint 11c away from the accommodation cavity 11a to shield the joint 11c on the same side.

[0054] The waterproof cover 131 is used to shield the joint 11c, which can prevent liquid such as rainwater and condensed water from entering the accommodation cavity 11a of the electric control box 10 from the joint 11c. Exemplarily, to further improve the waterproof performance of the waterproof cover 131, a folded edge or a folded edge can be provided at one end of the waterproof cover 131 close to the first box body 111 in the third direction, and the folded edge or the folded edge extends towards the box body assembly 11, that is, the folded edge or the folded edge can further block the liquid such as rainwater and condensed water.

[0055] The waterproof cover 131 can be arranged only on the second side X2, or only on the third side X3, or waterproof covers 131 can be arranged on both the second side X2 and the third side X3. For ease of description, the waterproof cover 131 arranged on the second side X2 of the box body assembly 11 can be referred to as the first waterproof cover 1311, and the waterproof cover 131 arranged on the third side X3 of the box body assembly 11 can be referred to as the second waterproof cover 1312.

[0056] For the first waterproof cover 1311 arranged on the second side X2 of the box body assembly 11, shielding the joint 11c means that the projection of the joint 11c on the second side X2 is located within the projection area of the first waterproof cover 1311 in the projection plane perpendicular to the first direction.

[0057] For the second waterproof cover 1312 arranged on the third side X3 of the box body assembly 11, shielding the seam 11c means that on the projection plane perpendicular to the second direction, the projection of the seam 11c on the third side X3 is located within the projection area of ​​the second waterproof cover 1312.

[0058] See also Figure 2 、 Figures 5 to 7 The housing 30 includes a housing body 31 and a housing cover 32. The housing cover 32 is disposed on a side of the housing body 31 that faces away from the water receiving tray 20. Figure 2 In the illustrated housing 30, the air inlet 30a is disposed on the housing body 31. In other embodiments, the air inlet 30a may also be disposed on the housing cover 32. For a head assembly in which the air inlet 30a is disposed on the housing body 31, a waterproof cover 131 may preferably be disposed on at least the second side X2 of the box assembly 11, the waterproof cover 131 being located between the box assembly 11 and the air inlet 30a.

[0059] That is to say, when the electronic control box 10 is set in the cover shell 30, the first waterproof cover 1311 is located between the box body assembly 11 and the air inlet 30a. The first waterproof cover 1311 can prevent rainwater entering from the air inlet 30a from entering the accommodating cavity 11a of the box body assembly 11 through the seam 11c of the second side X2 of the box body assembly 11.

[0060] See also Figure 4 、 Figure 8 、 Figure 9 、 Figure 11 and Figure 12 To further enhance the waterproof performance of the electronic control box 10, a waterproof cover 131, i.e., a second waterproof cover 1312, may also be provided on the third side X3 of the box body assembly 11. When the electronic control box 10 is disposed within the housing 30, the second waterproof cover 1312 is located on the side of the box body assembly 11 near the housing cover 32, thereby effectively preventing rainwater entering through the air inlet 30a from entering the accommodating cavity 11a of the box body assembly 11 through the seam 11c on the third side X3 of the box body assembly 11.

[0061] In addition, the first waterproof cover 1311 and the second waterproof cover 1312 may be connected at their respective sides so as to further block rainwater.

[0062] It is understandable that, for the head assembly in which the air inlet 30a is provided on the shell cover 32 , a waterproof cover 131 may be provided at least on the third side X3 of the box body assembly 11 .

[0063] An embodiment of the present application also provides a heat pump water heater, which includes a water tank assembly and a head assembly provided by any embodiment of the present application. The head assembly is arranged on the water tank assembly, that is, this heat pump water heater is an integrated heat pump water heater.

[0064] The head assembly is generally arranged at the top of the water tank assembly along the height direction. In other embodiments, the head assembly can also be arranged at other positions of the water tank assembly.

[0065] The water tank assembly has an outer shell and an inner tank and a water tank heat exchanger arranged in the outer shell. The inner tank is used to store domestic water. The water tank heat exchanger can heat the domestic water in the inner tank into hot water by exchanging heat with the heat exchanger 40 in the head assembly.

[0066] The electric control box 10 of the embodiment of the present application is provided with a waterproof component 13 having a waterproof cover 131 on the outside of the box body component 11. The waterproof cover 131 is provided on at least one of the second side X2 and the third side X3 of the box body component 11 to cover the seam 11c on the same side. For the head assembly provided with such an electric control box 10, by orienting the fourth side X4 of the box body component 11 toward the water receiving tray 20 and the first side X1 of the box body component 11 closer to the heat exchanger 40 than the second side X2, the heat exchanger 40 can be prevented from leaking. This allows the cable opening 11b of the box assembly 11 to avoid the air inlet 30a, thereby reducing the probability of rainwater entering the accommodating chamber 11a through the cable opening 11b. Furthermore, the second side X2 and the third side X3 of the box assembly 11 are relatively close to the air inlet 30a. Therefore, by providing a waterproof cover 131 on at least one of the second side X2 and the third side X3, rainwater can also be prevented from entering the accommodating chamber 11a through the seam 11c of the second side X2 and / or the third side X3. Therefore, the electric control box 10 of the embodiment of the present application has excellent waterproof performance.

[0067] It should be noted that the electrical control box 10 of the embodiment of the present application is not limited to use in an integral heat pump water heater. The electrical control box 10 can also be used in a split heat pump water heater (a split heat pump water heater has an independent heat pump external unit, and the electrical control box 10 is arranged in the heat pump external unit) and any other electrical equipment that requires the use of the electrical control box 10.

[0068] In one embodiment, please refer to Figure 11 and Figure 12 For the electric control box 10 with the first waterproof cover 1311, the first waterproof cover 1311 can be provided with a ground wire installation opening 1311a. In other words, the waterproof cover 131 provided on the second side X2 of the box body assembly 11 can not only be used to cover the seam 11c of the box body assembly 11 on the second side X2, but can also serve to secure the ground wire.

[0069] In another embodiment, a separate ground wire mounting plate may also be provided. For example, the box assembly 11 may further provide a ground wire mounting plate on the second side X2 , and the ground wire mounting plate is located on one side of the first waterproof cover 1311 along the second direction.

[0070] In one embodiment, please refer to Figure 5 、 Figure 9 、 Figure 10 and Figure 12 The waterproof assembly 13 may include a connecting plate 132 connected to the waterproof cover 131 , and the connecting plate 132 is located on a side of the second box body 112 away from the first box body 111 along the first direction.

[0071] The connecting plate 132 is used to fix the waterproof cover 131. For example, the waterproof cover 131 can be supported by the connecting plate 132 to maintain a position covering the seam 11c on the same side, thereby improving the installation stability of the waterproof cover 131.

[0072] For example, see Figure 12 The waterproof assembly 13 can be an integrated structure, and the waterproof assembly 13 is formed by bending to form a connecting plate 132 and a waterproof cover 131. In particular, for the waterproof assembly 13 using sheet metal parts, the connecting plate 132 and the waterproof cover 131 are formed by bending, which can improve production efficiency and reduce production costs.

[0073] In one embodiment, please refer to Figure 5 、 Figure 6 、 Figures 8 to 12 The waterproof cover 131 may further include a protective cover 133 , which is located on the first side X1 of the box assembly 11 and defines a wire passing space 133 a communicating with the wire passing port 11 b between the protective cover 133 and the wire passing port 11 b .

[0074] The protective cover 133 is used to protect the cables. The wire-passing space 133a is used for passing the cables.

[0075] See also Figure 5 and Figure 6 The heat exchanger 40 can be located on the side of the protective cover 133 away from the wire passing space 133a. In other words, the protective cover 133 can prevent the wire body from contacting the heat exchanger 40.

[0076] For example, see Figure 5 The heat exchanger 40 has a refrigerant inlet and outlet pipe side 40a, and the side of the heat exchanger 40 opposite to the refrigerant inlet and outlet pipe side 40a has a side plate 41. The electrical control box 10 can be arranged on the side of the heat exchanger 40 opposite to the refrigerant inlet and outlet pipe side 40a, and the protective cover 133 is connected to the side plate 41.

[0077] The refrigerant inlet and outlet pipe side 40a refers to the side of the heat exchanger 40 that connects to the refrigerant gas and liquid pipes. Placing the electrical control box 10 on the side of the heat exchanger 40 opposite the refrigerant inlet and outlet pipe side 40a ensures that the layout of the refrigerant gas and liquid pipes is not affected. Connecting the protective cover 133 to the side plate 41 improves the installation stability of the protective cover 133.

[0078] For an embodiment in which the waterproof assembly 13 includes a connecting plate 132, see Figure 5 、 Figure 10 and Figure 12 The connecting plate 132 can be connected with the protective cover 133, and the connecting plate 132 is located at a side of the second box body 112 away from the first box body 111 in the first direction. That is, the protective cover 133 and the waterproof cover 131 are connected with the connecting plate 132 respectively, which can not only improve the mounting stability of the protective cover 133, but also improve the integrity of the waterproof assembly 13 and improve the assembly efficiency of the waterproof assembly 13.

[0079] Exemplarily, please refer to Figure 6 , Figure 8 , Figure 10 The second box body 112 can include a box body 1121 and a boss 1122 with a wire passing port 11b, the box body 1121 defines the accommodating cavity 11a together with the first box body 111, and the boss 1122 is located outside the box body 1121, and the protective cover 133 is located at a side of the boss 1122 away from the first box body 111 in the first direction.

[0080] By arranging the wire passing port 11b on the boss 1122, the liquid such as rainwater and condensed water can be better prevented from entering the accommodating cavity 11a.
