[0040] In the absence of conflict, the embodiments and technical features in the embodiments of this application can be combined with each other. The detailed description in the specific implementation method should be understood as an explanation of the purpose of this application and should not be regarded as an improper limitation on this application.

[0041] It should be noted that in the embodiments of the present application, "down" refers to the direction of the ground, and "up" is the opposite of "down". In the embodiments of the present application, the orientation or positional relationship of "up" and "down" is based on the orientation or positional relationship shown in the accompanying drawings. It should be understood that these orientation terms are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, they should not be understood as limitations on the present application. The present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0042] It should be noted that, in the embodiments of the present application, a plurality includes two and more than two.

[0043] See also Figures 1 to 4 The electrical control box 1 is used to provide control functions for electrical equipment. For example, the electrical control box 1 can control the electrical equipment's power on / off or mode selection. Electrical equipment includes, but is not limited to, a heat pump water heater 100. It is understood that the electrical control box 1 can also be used with electrical equipment other than the heat pump water heater 100, such as a heat pump air conditioning system. The present embodiment uses the heat pump water heater 100 as an example for description.

[0044] See also Figures 1 to 4The embodiment of the present application provides a head assembly 10, and the head assembly 10 comprises the electric control box 1 in any embodiment of the present application.

[0045] The head assembly 10 can be used in the heat pump water heater 100, and the head assembly 10 can integrate at least part of electrical components in the heat pump water heater 100.

[0046] Please refer to Figures 1 to 4 The embodiment of the present application provides a heat pump water heater 100, and the heat pump water heater 100 comprises the head assembly 10 in any embodiment of the present application. That is to say, the electric control box 1 provided by the embodiment of the present application can be used in the heat pump water heater 100.

[0047] The heat pump water heater 100 can also be a variable frequency heat pump water heater, that is to say, the control mainboard can be provided with a frequency converter, and the compressor 105 can be a variable frequency compressor, and the frequency converter can adjust the frequency of the variable frequency compressor.

[0048] In the related art, the electric control box comprises an upper cover and a lower cover, the upper cover and the lower cover are buckled to define an installation cavity, the electric control mainboard is located in the installation cavity and connected with the upper cover, the upper cover is provided with a rotating shaft, the lower cover has an open slot for accommodating the rotating shaft, the rotating shaft enters the open slot through the opening of the open slot, and rotating connection between the upper cover and the lower cover is realized. Since the conductive wire needs to be electrically connected with the device outside the electric control box, that is to say, one end of the conductive wire needs to be fixed outside the electric control box, therefore, the terminal of the conductive wire needs to be inserted on the electric control mainboard first, and then the upper cover can be assembled to the lower cover. In the electric control box assembly process, the rotating shaft enters the open slot through the opening of the open slot, the open slot is usually a straight slot extending in a straight line, and since the included angle between the upper cover and the lower cover is greater than 90°, the rotating shaft is easy to be pulled out of the open slot, so that the upper cover falls off, therefore, the upper cover needs to be rotated to an included angle less than 90° with the lower cover, and then a tool is used to support the upper cover. In the wire assembly process of assembling the conductive wire to the electric control mainboard, the upper cover needs to be manually held to avoid the upper cover continuing to rotate away from the lower cover to cause the included angle to be greater than 90°. This assembly mode is inconvenient to operate, the production efficiency is relatively low, a tool is needed to support the upper cover, the production cost is increased, and the operator is also easy to misoperate, causing the upper cover to fall off, damaging the electric control mainboard or other structural parts, and causing losses.

[0049] Please refer to Figures 4 and 5 The embodiment of the present application provides an electric control box 1, and the electric control box 1 comprises a box cover assembly 11, an electric control mainboard 12 and a box body assembly 13.

[0050] The electric control mainboard 12 is a key component of the electric control box 1, the electric control mainboard 12 provides a control function, and the electric control mainboard 12 can be a circuit board provided with a circuit and electrical elements.

[0051] The electronic control motherboard 12 can be electrically connected to the electrical components of the electrical equipment through conductive wires to control the electrical components. The electrical components include but are not limited to at least one of a motor, a compressor 105, a throttling device, an electronic control switch, a display panel, and a sensor.

[0052] The box cover assembly 11 includes a box cover body 111 and a pin 112 disposed on the box cover body 111 (see Figure 5 The pin 112 is connected to the box cover body 111.

[0053] The electronic control mainboard 12 is disposed on the box cover body 111 .

[0054] See also Figures 4 to 12 The box body assembly 13 includes a box body main body 131 and a mounting seat 132. The mounting seat 132 is connected to the circumference of the box body main body 131. The mounting seat 132 forms a guide groove 132a and a limit groove 132b. One end of the guide groove 132a has a mounting opening 132ab. The limit groove 132b is connected to the guide groove 132a and extends from the guide groove 132a toward the box body main body 131. The shaft 1121 of the pin 112 passes through the mounting opening 132ab and enters the limit groove 132b along the guide groove 132a. The box cover main body 111 has an open state relative to the box body main body 131 and a locked state. When the box cover main body 111 is in the open state, the shaft 1121 abuts the groove wall surface of the limit groove 132b.

[0055] The peripheral side of the box body 131 refers to a straight side wall of the box body 131 extending in the vertical direction.

[0056] See also Figure 6 and Figure 7 The box cover body 111 is in an open state, for example, the angle between the box cover body 111 and the box body 131 is greater than 0°. In other words, the box cover body 111 is in a standing posture, the box cover body 111 does not close the upward opening of the box body 131, and the internal structure of the box body 131 can be exposed.

[0057] When the box cover body 111 is in the open state, the electronic control main board 12 and the box cover body 111 remain in an upright position, and the electronic control main board 12 can face the operator to facilitate the operator to assemble the conductive wires to the electronic control main board 12.

[0058] The limiting groove 132b extends from the guide groove 132a toward the direction close to the box body 131. When the box cover body 111 is in the open state, the upper wall of the limiting groove 132b abuts against the shaft body 1121, exerting a downward force on the shaft body 1121. The angle between the box cover body 111 and the box body 131 can be greater than 90° and less than 180°.

[0059] See also Figure 5 and Figure 10 The box cover body 111 is in a buckled state. For example, the angle between the box cover body 111 and the box body 131 can be equal to 0°. In other words, the box cover body 111 is in a prone position, and the box cover body 111 closes the upward opening of the box body 131, and the internal structure of the box body 131 cannot be exposed.

[0060] When the box cover body 111 is in the buckled state, the electronic control motherboard 12 and the box cover body 111 remain in a prone position, and the electronic control motherboard 12 can face the box body 131. The electronic control motherboard 12 is accommodated in the placement cavity defined by the box cover body 111 and the box body 131.

[0061] The shaft 1121 moves in the limiting groove 132b to switch the box cover body 111 between the open state and the buckled state. In other words, the box cover body 111 can rotate relative to the box body 131 to open or buckle the box body 131.

[0062] The limiting groove 132b extends from the guide groove 132a toward the box body 131, that is, at least a portion of the limiting groove 132b is located on the side of the guide groove 132a that is close to the box body 131. When the box cover body 111 is in the open state, the shaft body 1121 abuts against the groove wall of the limiting groove 132b close to the box body 131. The groove wall of the limiting groove 132b close to the box body 131 can prevent the shaft body 1121 from entering the guide groove 132a. The interaction force between the groove wall of the limiting groove 132b close to the box body 131 and the shaft body 1121 can also limit the box cover body 111 from continuing to rotate in the direction away from the box body 131, so that the box cover body 111 maintains an upright posture.

[0063] For the convenience of description, in this application, the side close to the operator is defined as the front side, and the rear side is opposite to the front side, and the rear side is the side away from the operator.

[0064] As an example, during the assembly process of the electric control box 1, that is, during the production line production of the electric control box 1, the shaft body 1121 of the pin shaft 112 passes through the installation opening 132ab and enters the limiting groove 132b along the guide groove 132a, and at least part of the groove section of the limiting groove 132b is located on the front side of the guide groove 132a. When the box cover body 111 is in the open state, the shaft 1121 abuts against the groove wall of the limiting groove 132b close to the box body 131. The groove wall of the limiting groove 132b close to the box body 131 can stop the shaft 1121 from entering the guide groove 132a. It can also limit the box cover body 111 from continuing to rotate toward the rear side through the interaction force between the groove wall of the limiting groove 132b close to the box body 131 and the shaft 1121. In this way, the box cover body 111 can be stably maintained in an upright position without falling. The operator does not need to hold the box cover body 111 with one hand, and there is no need to add additional tooling to support the box cover body 111. The conductive wire can be assembled to the electronic control motherboard 12 set on the box cover body 111 with both hands, which is simple to operate.

[0065] The embodiment of the present application provides an electric control box 1, in which the shaft 1121 abuts against the groove wall of the limiting groove 132b, and the box cover body 111 can be maintained in an open state. The box cover body 111 can be stably maintained in an upright position without falling. The operator does not need to hold the box cover body 111 with one hand, and does not need to add additional tooling to support the box cover assembly 11. The operator can use both hands to assemble the conductive wire to the electric control main board 12 arranged on the box cover body 111. The operation is simple, reduces the difficulty of wiring, improves production efficiency, and can also reduce the risk of product damage caused by the box cover body 111 falling.

[0066] It is understandable that the size of the shaft body 1121 can be slightly smaller than the width of the guide groove 132a, and the size of the shaft body 1121 can be slightly smaller than the width of the limiting groove 132b, so that the shaft body 1121 can easily pass through the guide groove 132a and enter the limiting groove 132b.

[0067] As an example, the shaft body 1121 may be substantially cylindrical.

[0068] For some examples, see Figure 8 and Figure 9 The pin 112 includes a stopper 1122, which can be connected to one axial end of the shaft 1121. The stopper 1122 can be located on the side of the limiting groove 132b away from the shaft 1121. The stopper 1122 protrudes from the limiting groove 132b and is used to prevent the shaft 1121 from moving axially. The stopper 1122 can reduce the risk of the shaft 1121 axially dislodging from the limiting groove 132b to a certain extent.

[0069] In some embodiments, the back of the electronic control board 12 can face the box cover body 111, and the front of the electronic control board 12 can face away from the box cover body 111, and the electrical components can be fixed to the front of the electronic control board 12. When the box cover body 111 is in the buckled state, the front of the electronic control board 12 can face downward.

[0070] In this embodiment, when the box cover body 111 is in the open state, the angle between the front face of the electronic control main board 12 and the horizontal plane is greater than 0°. The angle between the front face of the electronic control main board 12 and the horizontal plane can be greater than 90°. For example, the angle between the front face of the electronic control main board 12 and the horizontal plane can be 120°. In this way, the front face of the electronic control main board 12 can face the operator, making it easier for the operator to check the installation position of the conductive wires on the electronic control main board 12. When the box cover body 111 is in the buckled state, the front face of the electronic control main board 12 can face downward, and the electrical components arranged on the front face are located below the electronic control main board 12.

[0071] The connection method between the electronic control board 12 and the box cover body 111 is not limited. The electronic control board 12 and the box cover body 111 can be detachably connected or non-detachably connected. Removable connections include, but are not limited to, snap connections and / or fastener connections. Non-detachable connections include, but are not limited to, bonding and / or welding.

[0072] Fasteners include but are not limited to screws or bolts, etc.

[0073] There is no limitation on the connection method between the conductive wire and the electronic control main board 12 . The conductive wire can be plugged or clipped to the electronic control main board 12 through a wire terminal.

[0074] For some examples, see Figure 3 The electrical control box 1 includes a heat sink 14. One end of the heat sink 14 can be fixed to the front of the electrical control mainboard 12, and the other end of the heat sink 14 can extend to the outside of the electrical control box 1. For example, the other end of the heat sink 14 can extend below the box body 131. The heat sink 14 can transfer heat generated by the electrical control mainboard 12 and electrical components to the external environment of the electrical control box 1, thereby reducing the temperature of the electrical control mainboard 12 and electrical components, achieving the purpose of heat dissipation and cooling.

[0075] The heat sink 14 can be made of a good thermal conductor material such as aluminum or copper.

[0076] For some examples, see Figure 5 and Figure 6 , the box body main body 131 is placed roughly horizontally. That is, the surface with the largest area of ​​the box body main body 131 is roughly parallel to the horizontal plane, and the thickness direction of the box body main body 131 is perpendicular to the horizontal direction.

[0077] For some examples, see Figure 5 and Figure 6The guide groove 132a extends through the upward end face of the mounting seat 132 to form a mounting opening 132ab. That is, the upward end face of the mounting seat 132 forms the mounting opening 132ab, and the mounting opening 132ab faces upward. In this way, on the one hand, the field of view is better, and it is convenient for the operator to align the shaft body 1121 with the mounting opening 132ab. On the other hand, the risk of the shaft body 1121 falling out of the mounting opening 132ab can be reduced.

[0078] In some embodiments, referring to Figures 5 to 12 The end of the guide groove 132a away from the mounting opening 132ab is inclined away from the box body 131.

[0079] In this embodiment, the guide groove 132a is substantially a chute inclined to the up-down direction. When the box cover body 111 is in the open state, the included angle between the guide groove 132a and the limiting groove 132b is less than 90°, and the shaft body 1121 is difficult to enter the guide groove 132a from the limiting groove 132b.

[0080] In some embodiments, referring to Figure 9 The guide groove 132a has a first central axis L1, and the included angle between the first central axis L1 and the vertical direction is α, 0°<α≤80°.

[0081] The first central axis L1 is the connecting line of the center points of the cross section of the guide groove 132a, and is also a straight line parallel to the extension direction of the guide groove 132a.

[0082] For example, the first central axis L1 extends from the mounting opening 132ab to the direction away from the box body 131, that is, the first central axis L1 extends from the mounting opening 132ab to the rear.

[0083] In this embodiment, the included angle between the first central axis L1 and the vertical direction is greater than 0° and not greater than 80°, and the guide groove 132a is substantially a chute inclined to the up-down direction. When the box cover body 111 is in the open state, the shaft body 1121 is difficult to enter the guide groove 132a from the limiting groove 132b.

[0084] In some embodiments, referring to Figure 9 The end of the limiting groove 132b close to the box body 131 is inclined upward or parallel to the horizontal plane. That is, the front end of the limiting groove 132b is inclined upward or parallel to the horizontal plane.

[0085] For example, in some embodiments, the limiting groove 132b gradually extends upward from the opening groove. In other embodiments, referring to Figure 9 The limiting groove 132b extends along the horizontal plane from the opening groove.

[0086] In this embodiment, the end of the limiting groove 132b close to the box body 131 is inclined upward or parallel to the horizontal plane. On the one hand, when the box cover body 111 is in the open state, the contact area between the groove wall of the limiting groove 132b at one end close to the box body 131 and the shaft body 1121 is relatively large, and the groove wall of the limiting groove 132b can more effectively exert a downward force on the shaft body 1121. The limiting groove 132b can more stably press the shaft body 1121, and the box cover body 111 and the control main board can maintain a more stable upright posture, reducing the shaking of the box cover body 111 and the control main board, and the shaft body 1121 is difficult to enter the guide groove 132a from the limiting groove 132b; on the other hand, the angle between the box cover body 111 and the box body 131 can be greater than 90°, and the angle between the front of the control main board and the box body 131 is greater than 90°, which is convenient for the operator to install the conductive wire to the control main board.

[0087] For some examples, see Figure 9 The limiting groove 132b has a second central axis L2, and the angle between the second central axis L2 and the horizontal plane is β, 0°≤β≤45°.

[0088] The second central axis L2 is a line connecting the center points of the cross sections of the limiting groove 132 b and is also a straight line parallel to the extending direction of the limiting groove 132 b.

[0089] As an example, in some embodiments, the second central axis L2 extends obliquely upward, that is, the second central axis L2 extends obliquely forward. In some embodiments, the second central axis L2 extends obliquely horizontally, that is, the second central axis L2 extends obliquely horizontally forward.

[0090] In this embodiment, the angle between the second central axis L2 and the horizontal direction is not less than 0° and not greater than 45°. On the one hand, when the box cover main body 111 is in the open state, the contact area between the groove wall surface of the limiting groove 132b at one end close to the box body main body 131 and the shaft body 1121 is relatively large, and the groove wall surface of the limiting groove 132b can more effectively exert a downward force on the shaft body 1121. The limiting groove 132b can more stably press the shaft body 1121, and the box cover main body 111 and the control main board can more stably maintain an upright posture, reducing the shaking of the box cover main body 111 and the control main board, and the shaft body 1121 is difficult to enter the guide groove 132a from the limiting groove 132b; on the other hand, the angle between the box cover main body 111 and the box body main body 131 can be greater than 90°, and the angle between the front of the control main board and the box body main body 131 is greater than 90°, which is convenient for the operator to install the conductive wire to the control main board.

[0091] For some examples, see Figures 3 to 12The box cover assembly 11 includes a bracket 113, a pin 112 is arranged on the bracket 113, the box cover body 111 includes a metal box cover 1111, the metal box cover 1111 includes a first side wall 11111 and a second side wall 11112, the second side wall 11112 is connected to the first side wall 11111 and extends in a direction away from the first side wall 11111, and the bracket 113 is connected to both the first side wall 11111 and the second side wall 11112.

[0092] The metal box cover 1111 is a metal structure made of metal material.

[0093] The first side wall 11111 and the second side wall 11112 are connected and intersected. The first side wall 11111 and the second side wall 11112 can both be two side walls of the circumferential wall of the metal box cover 1111.

[0094] In this embodiment, the metal cover 1111 can improve the fireproof performance of the cover body 111. The bracket 113 is connected to both the first side wall 11111 and the second side wall 11112. When the cover body 111 is in the open state, the force applied by the operator when installing the electronic control motherboard 12 and the conductive wires is transmitted to the connection between the bracket 113 and the first side wall 11111 and the second side wall 11112, thereby improving the force-bearing performance, effectively enhancing the connection strength of the bracket 113, and reducing the risk of the bracket 113 falling off.

[0095] In some embodiments, the bracket 113 may be a metal structure. The bracket 113 has good structural strength.

[0096] In some embodiments, the bracket 113 may be an integrally formed structure. For example, the bracket 113 may be a sheet metal structure formed by a sheet metal process.

[0097] The sheet metal structure refers to a structure formed by cold working such as stamping, shearing or bending a metal plate. For example, the bracket 113 may be a structure formed by cold working such as stamping, shearing or bending a metal plate.

[0098] The connection method between the pin shaft 112 and the bracket 113 is not limited. For example, the pin shaft 112 and the bracket 113 can be welded.

[0100] The metal box body 1311 is a metal structure made of metal material.

[0101] The third side wall 13111 and the fourth side wall 13112 are connected and intersected. The third side wall 13111 and the fourth side wall 13112 can both be two side walls of the circumferential wall of the metal box body 1311.

[0102] In this embodiment, the metal box body 1311 can improve the fireproof performance of the box body 131. The mounting seat 132 is connected to both the third side wall 13111 and the fourth side wall 13112. When the pin 112 is plugged into the mounting seat 132, the force applied by the operator when installing the electronic control motherboard 12 and the conductive wires is transmitted to the connection between the mounting seat 132 and the third and fourth side walls 13111 and 13112, thereby improving the force-bearing performance, effectively enhancing the connection strength of the mounting seat 132, and reducing the risk of the mounting seat 132 falling off.

[0103] In some embodiments, the mounting base 132 includes two side panels, an end panel, and two support panels. The end panel is spaced apart from the metal box body 1311. The two side panels are connected to opposite sides of the end panel, respectively. The two support panels are connected to the two side panels, respectively. One support panel is connected to the first side wall 11111, and the other support panel extends from the first side wall 11111 to the second side wall 11112. At least one side panel forms a mounting opening 132ab, a guide groove 132a, and a retaining groove 132b. For example, a single side panel of a single mounting base 132 may form the mounting opening 132ab, the guide groove 132a, and the retaining groove 132b. In another example, the two side panels of a single mounting base 132 may form the mounting opening 132ab, the guide groove 132a, and the retaining groove 132b. In this manner, the mounting base 132 has a simple structure and is relatively lightweight.

[0104] In some embodiments, the pin 112 is a metal structure. The pin 112 has good structural strength and can stably support the box cover body 111 and the control motherboard.

[0105] In some embodiments, the mounting base 132 is a metal structure. The mounting base 132 has good structural strength and can stably support the box cover body 111 and the control motherboard.

[0106] The mounting seat 132 may be an integrally formed structure. For example, the mounting seat 132 may be a sheet metal structure formed by a sheet metal process.

[0107] The connection method of the mounting base 132 to the first side wall 11111 and the second side wall 11112 is not limited. For example, the mounting base 132 can be welded to the first side wall 11111 or connected by fasteners. The mounting base 132 can be welded to the second side wall 11112 or connected by fasteners.

[0108] It should be noted that, in some embodiments, the pin 112 can be made of plastic, the bracket 113 can be made of plastic, and the mounting base 132 can also be a plastic structure. Plastic is light in weight and relatively low in cost.

[0109] In order to improve the fire prevention effect, at least one of the pin 112, the bracket 113 and the mounting seat 132 can be made of flame-retardant plastic.

[0110] For some examples, see Figures 5 to 12 There are multiple pins 112 and multiple mounting seats 132 , and the multiple mounting seats 132 are spaced apart along the length direction of the box body 131 , and each pin 112 corresponds to one mounting seat 132 .

[0111] As an example, there may be multiple brackets 113 , and each bracket 113 is provided with a pin shaft 112 .

[0112] In this embodiment, the plurality of mounting seats 132 and the plurality of pins 112 can more stably keep the box cover body 111 in the open state.

[0113] For some examples, see Figures 3 to 12 There are two brackets 113, each bracket 113 can be provided with a pin shaft 112, the metal box cover 1111 includes two second side walls 11112, the two second side walls 11112 are respectively connected to the two ends of the first side wall 11111, the two second side walls 11112 extend in the same direction, and the two brackets 113 are both connected to the same first side wall 11111 and are respectively connected to a second side wall 11112.

[0114] In this embodiment, two brackets 113 can be respectively provided at both ends of the metal box cover 1111. The two brackets 113 are subjected to more balanced forces, and the box cover body 111 is kept more stably in the open state.

[0115] As an example, in some embodiments, the first side wall 11111 and the second side wall 11112 are both welded to the bracket 113. In some embodiments, the first side wall 11111 and the second side wall 11112 are both connected to the bracket 113 via fasteners.

[0116] It is understandable that the number of brackets 113 may be more than two.

[0117] For some examples, see Figures 3 to 12 There are two mounting seats 132, the metal box body 1311 includes two fourth side walls 13112, the two fourth side walls 13112 are respectively connected to the two ends of the third side wall 13111, the two fourth side walls 13112 extend in the same direction, and the two mounting seats 132 are both connected to the same third side wall 13111 and are respectively connected to one fourth side wall 13112.

[0118] In this embodiment, two mounting seats 132 can be respectively provided at both ends of the metal box body 1311 . The two mounting seats 132 are subjected to more balanced forces, and the box cover body 111 is kept in an open state more stably.

[0119] As an example, in some embodiments, the third side wall 13111 and the fourth side wall 13112 are both welded to the mounting base 132. In some embodiments, the third side wall 13111 and the fourth side wall 13112 are both connected to the mounting base 132 via fasteners.

[0120] It is understandable that the number of mounting seats 132 may be more than two.

[0121] For some examples, see Figures 3 to 6 The box cover body 111 includes a metal box cover 1111 and a plastic box cover 1112 , and the metal box cover 1111 covers the outside of the plastic box cover 1112 .

[0122] In some embodiments, the bracket 113 may be connected to the metal cover 1111 . Alternatively, the bracket 113 may be connected to the plastic cover 1112 .

[0123] The plastic box cover 1112 can improve the insulation performance of the box cover body 111 , and the metal box cover 1111 can improve the fireproof performance of the box cover body 111 .

[0124] The metal box cover 1111 covers the outside of the plastic box cover 1112 means that the metal box cover 1111 covers at least part of the outer surface of the plastic box cover 1112, for example, the metal box cover 1111 covers the entire outer surface of the plastic box cover 1112 or covers part of the outer surface of the plastic box cover 1112.

[0125] As an example, the shape of the metal box cover 1111 can be adapted to the shape of the plastic box cover 1112 , and the metal box cover 1111 and the plastic box cover 1112 can be nested to form a double-layer structure.

[0126] For some examples, see Figures 3 to 6 The box body 131 includes a metal box body 1311 and a plastic box body 1312 , and the metal box body 1311 covers the outside of the plastic box body 1312 .

[0127] In some embodiments, the mounting base 132 may be connected to the metal cover 1111 . Alternatively, the mounting base 132 may be connected to the plastic cover 1112 .

[0128] The plastic box body 1312 can improve the insulation performance of the box body main body 131 , and the metal box body 1311 can improve the fireproof performance of the box body main body 131 .

[0129] The metal box body 1311 covering the outside of the plastic box body 1312 means that the metal box body 1311 covers at least part of the outer surface of the plastic box body 1312 , for example, the metal box body 1311 covers the entire outer surface of the plastic box body 1312 or covers part of the outer surface of the plastic box body 1312 .

[0130] As an example, the shape of the metal box body 1311 may match the shape of the plastic box body 1312 , and the metal box body 1311 and the plastic box body 1312 are nested to form a double-layer structure.

[0131] For some examples, see Figures 2 to 6 The head assembly 10 includes a wind wheel and a heat exchanger 101 , and the wind wheel and the box body 131 are located on opposite sides of the heat exchanger 101 .

[0132] The wind wheel is used to drive the air flow.

[0133] The heat exchanger 101 is used to realize heat exchange between the refrigerant and the air flow.

[0134] As an example, the heat exchanger 101 may be a substantially plate-shaped structure, with the wind wheel and the box body 131 located on opposite sides of the heat exchanger 101 along the thickness direction.

[0135] In this embodiment, the impeller drives the airflow through the box body 131 and the heat exchanger 101 in sequence. One end of the heat sink 14 extends below the box body 131. The box body 131 is positioned approximately horizontally. That is, the largest surface of the box body 131 is approximately parallel to the horizontal plane, and the thickness of the box body 131 is perpendicular to the horizontal direction. This minimizes the obstruction of the box body 131 to the airflow, allowing the airflow to exchange heat with both the heat sink 14 and the heat exchanger 101. The impeller and the box body 131 are located on opposite sides of the heat exchanger 101. The box body 131 and the heat exchanger 101 are approximately on the same airflow path, facilitating heat exchange with the airflow and achieving a more compact structural layout.

[0136] For some examples, see Figures 2 to 6 The head assembly 10 includes an air guide shell 102 , and the electric control box 1 is connected to the air guide shell 102 .

[0137] The electric control box 1 is connected to the air guide housing 102 , and the air guide housing 102 can provide support for the electric control box 1 . For example, the support plate 15 can be fixed to the upper end of the air guide housing 102 .

[0138] In this embodiment, during the production line process, the box body 131 can be first assembled to the air guide shell 102, the pin shaft 112 can be placed in the limiting groove 132b, and then the electric control box 1 and the conductive wire can be assembled.

[0139] In some embodiments, the wind wheel may be located in the wind guide housing 102. The wind guide housing 102 is used to provide a flow guide for the wind wheel so that the airflow flows along a set path.

[0140] For some examples, see Figures 2 to 6 The head assembly 10 includes a shell 103, which is formed with a accommodating cavity, an air inlet 103a and an air outlet 103b. The air inlet 103a and the air outlet 103b are both connected to the accommodating cavity, and the heat exchanger 101, the electric control box 1 and the wind wheel are all located in the accommodating cavity.

[0141] In this embodiment, the shell 103 provides protection for the heat exchanger 101, the electrical control box 1 and the wind wheel, and the air inlet 103a and the air outlet 103b can both be connected to the external environment of the shell 103. During the rotation of the wind wheel, air from the external environment can enter the accommodating cavity through the air inlet 103a, flow through the electrical control box 1 and the heat exchanger 101, and then be discharged through the air outlet 103b.

[0142] For some examples, see Figures 2 to 6 The head assembly 10 includes a support rod 104 , and the lower end of the box body 131 is connected to the support rod 104 .

[0143] As an example, the support rod 104 may be located in the accommodating cavity, and the support rod 104 may be connected to a portion of the box body 131 away from the heat exchanger 101 .

[0144] In this embodiment, the support rod 104 can support the box body 131 upward, so that the electric control box 1 is stably assembled. The support rod 104 can also reduce the obstruction to the airflow.

[0145] For some examples, see Figures 2 to 6 The head assembly 10 includes a compressor 105 , which is located below the box body 131 .

[0146] The compressor 105 is used to drive the flow of refrigerant.

[0147] In this embodiment, the compressor 105 is located below the box body 131 , and has a compact structure, which is conducive to the miniaturization of the head assembly 10 .

[0148] For some examples, see Figures 2 to 6 One end of the box body 131 is connected to the air guide shell 102 through the support plate 15, and the other end of the box body 131 is connected to the support rod 104. The compressor 105 can be located between the heat exchanger 101 and the support rod 104.

[0149] In this embodiment, the air guide housing 102 and the support rod 104 both provide support for the electrical control box 1, which ensures a stable installation. The compressor 105 is located between the heat exchanger 101 and the support rod 104. The wind wheel drives the airflow through the compressor 105, providing heat dissipation and cooling for the compressor 105.

[0150] For some examples, see Figures 2 to 6 The outer shell 103 may include an annular shell 1031, an end cover 1032 and a water receiving tray 1033. The annular shell 1031 is open at both ends in the up and down directions. The end cover 1032 closes the upper end opening of the annular shell 1031, and the water receiving tray 1033 closes the lower end opening of the annular shell 1031.

[0151] In this embodiment, the annular housing 1031 , the end cover 1032 and the water receiving tray 1033 together define a receiving cavity. The water receiving tray 1033 can receive condensed water from the heat exchanger 101 .

[0152] For some examples, see Figures 2 to 6 The circumferential wall of the housing 103 forms an air inlet 103a and an air outlet 103b. For example, the annular housing 1031 forms the air inlet 103a and the air outlet 103b. The air inlet 103a can be located on the side of the heat exchanger 101 away from the wind rotor, and the air outlet 103b can be located on the side of the heat exchanger 101 closer to the wind rotor.

[0153] In some embodiments, the air guide housing 102 can form an air guide channel with openings at opposite ends. The heat exchanger 101 shields one end opening of the air guide housing 102, and the portion of the housing 103 with the air outlet 103b can shield the other end opening of the air guide housing 102. The impeller can be located within the air guide channel. In this way, the air guide channel constrains the airflow path, reduces turbulence, and improves the heat exchange efficiency of the heat exchanger 101.

[0154] The heat pump water heater 100 regulates the water temperature by means of a heat pump. Figure 1 The heat pump water heater 100 includes a water tank assembly 20 and a heat exchanger.

[0155] The water tank assembly 20 is used to store water, and the heat exchanger can exchange heat with the water in the water tank assembly 20 to adjust the temperature of the water in the water tank assembly 20.

[0156] The water in the water tank assembly 20 can be used to supply users with domestic hot water to meet people's daily needs.

[0157] Refrigerant flows through both heat exchanger 101 and the heat exchanger. For example, heat exchanger 101, heat exchanger, compressor 105, and throttling device can be connected via a refrigerant pipe to form a refrigerant circulation path. Compressor 105 drives the refrigerant to circulate in the refrigerant circulation path. When the refrigerant flows through heat exchanger 101, the refrigerant exchanges heat with the airflow through heat exchanger 101. When the refrigerant flows through the heat exchanger, the refrigerant exchanges heat with the water through the heat exchanger.

[0158] The heat pump water heater 100 may further include a reversing device disposed in the refrigerant circulation path to change the flow direction of the refrigerant discharged from the compressor 105. In this way, the water can be provided with cooling and heating functions, providing hot and cold water to users.

[0159] The reversing device includes but is not limited to a four-way valve.

[0160] The throttling device includes but is not limited to a throttle valve.

[0161] For some examples, see Figure 1 The head assembly 10 can be arranged on the upper part of the water tank assembly 20. The head assembly 10 and the water tank assembly 20 are integrated together, and the heat pump water heater 100 has a compact structure and beautiful appearance. It is understandable that the head assembly 10 can also be arranged at other positions of the water tank assembly 20.

[0162] The refrigerant type in the embodiment of the present application is not limited. For example, the refrigerant includes but is not limited to fluoride refrigerants. For example, the refrigerant can be R290 (propane) refrigerant.
