Description

Technical Field

[0001] The present application relates to the technical field of electrical equipment, and in particular to an electric control box, a head assembly and a heat pump water heater. Background Art

[0002] In the related art, there is an electric control box of a heat pump water heater provided with an upper cover and a lower cover. The upper cover is openably and closably arranged on one side of the lower cover, and the electric control board is fixed on the upper cover. After the upper cover is arranged on the lower cover, the components of the electric control board face the lower cover.

[0003] Since other components of the heat pump water heater need to be electrically connected to the electric control board using cables, in order to facilitate wiring, the operator needs to first plug the terminals on the cables into the electric control board and then put the upper cover on the lower cover.

[0004] However, the heat pump water heater and the electrical control panel require a large number of cables to be electrically connected. These cables must be organized before the upper cover is placed on the lower cover. This is particularly difficult because the cables tend to fall loose after their terminals are plugged into the electrical control panel. Alternatively, the cables outside the electrical control box may be organized, but the cables inside remain tangled. Furthermore, the upper and lower covers of the electrical control box are prone to wire compression. Utility Model Content

[0052] In the description of the embodiments of the present application, it should be noted that the terms "first direction", "second direction" and "third direction" are based on the attached Figure 5 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.

[0053] An embodiment of the present application provides an electric control box 10, see Figures 3 to 7 、 Figure 10 and Figure 14 The electric control box 10 includes a box body assembly 11, an electric control board 12 and a wire fixing seat 13.

[0054] The box body assembly 11 includes a first box body 111 and a second box body 112. The second box body 112 can be opened and closed to cover one side of the first box body 111 along the first direction, and together with the first box body 111, define a accommodating cavity 11a. The second box body 112 is provided with a plurality of wire openings 112a arranged at intervals along the third direction and connected to the accommodating cavity 11a on one side of the second direction. The first direction, the second direction and the third direction are three mutually perpendicular directions of the box body assembly 11.

[0055] Figure 4 The first box body 111 shown is provided with a first shell 1111 and a second shell 1112 , and the second shell 1112 is provided in the first shell 1111 , that is, the first box body 111 can be composed of at least two shells.

[0056] The first shell 1111 and the second shell 1112 can be made of different materials. For example, the first shell 1111 can be made of metal, and the second shell 1112 can be made of plastic. The second shell 1112 made of plastic can play a certain insulating role, and the first shell 1111 made of metal can play a certain fire-proof and explosion-proof role. Therefore, the combination of the first shell 1111 made of metal and the second shell 1112 made of plastic can improve the safety of the electric control box 10.

[0057] In other embodiments, the first shell 1111 and the second shell 1112 may also be made of the same material.

[0058] Likewise, Figure 4 The second box body 112 shown is provided with a third shell 1121 and a fourth shell 1122 . The fourth shell 1122 is provided in the third shell 1121 , and a plurality of wire openings 112 a are provided in the fourth shell 1122 .

[0059] The third shell 1121 and the fourth shell 1122 may also be made of different materials. For example, the third shell 1121 may be made of metal, and the fourth shell 1122 may be made of plastic, so as to improve the safety of the electric control box 10 .

[0060] In other embodiments, the third shell 1121 and the fourth shell 1122 may also be made of the same material.

[0061] In some other embodiments, the first box body 111 may not be provided with the first shell 1111 and the second shell 1112 , that is, the first box body 111 may have only one shell.

[0062] The second box body 112 may not be provided with the third shell 1121 and the fourth shell 1122 , that is, the second box body 112 may also have only one shell.

[0063] The cable passing port 112a is used for passing cables, and the number of the cable passing port 112a can be two or more, and different cable passing ports 112a are used for passing different cables.

[0064] In some other embodiments, the two adjacent cable passing ports 112a can also be separated by a wall.

[0065] Please refer to Figures 5 to 7 , the cable passing port 112a is generally provided with a sealing piece 16 with a cable passing groove penetrating the sealing piece. The sealing piece is sealingly arranged at the cable passing port 112a to seal the cable passing port 112a.

[0066] The arrangement of the sealing piece at the cable passing port 112a is not limited. For example, the sealing piece can have a part of the structure located in the cable passing port 112a and another part of the structure located outside the cable passing port 112a. In another embodiment, the entire sealing piece can be located in the cable passing port 112a. In another embodiment, the sealing piece can be arranged outside the cable passing port 112a, for example, the sealing piece can be in sealing contact with the second box body 112 at the position located on the side of the cable passing port 112.

[0067] The cable passing through the cable passing port 112a is arranged in the cable passing groove and in contact with the groove wall of the cable passing groove to achieve better sealing effect.

[0068] Please refer to Figures 3 to 5 , Figure 10 , the electric control board 12 is arranged in the second box body 112 and located in the accommodating cavity 11a, that is, the electric control board 12 is fixed to the second box body 112. After the second box body 112 is opened, the electric control board 12 is located in the second box body 112, and after the second box body 112 is closed, the element face of the electric control board 12 faces the first box body 111. The element face of the electric control board 12 is the face where the electric control board 12 is provided with components, and is also the face where the cable is electrically connected.

[0069] Please refer to Figures 3 to 10 , the cable fixing seat 13 is arranged on the side of the second box body 112 provided with the plurality of cable passing ports 112a and located outside the box assembly 11.

[0070] The cable fixing seat 13 is used for fixing the cable electrically connected to the electric control board 12, and the cable fixing seat 13 is located outside the box assembly 11, that is, the cable fixing seat 13 fixes the part of the cable located outside the box assembly 11.

[0071] The cable holder 13 includes a holder body 131 and a cable securing structure disposed therein. The specific structure of the cable securing structure is not limited. For example, the cable securing structure may be a cable clip or cable trough capable of securing cables, or a cable post capable of being tied with a cable tie, with the cables being secured to the post using the cable tie. The cable securing structure may have a single structural form or a combination of multiple structural forms. For example, the cable securing structure may be one or a combination of at least two of a cable clip, a cable trough, and a cable post.

[0072] During the wiring process, the terminals on all cables can be inserted into the electric control board 12 and then each cable can be fixed on the wire fixing seat 13. Alternatively, each cable can be fixed on the wire fixing seat 13 first and then the terminals on the cables can be inserted into the electric control board 12. Alternatively, different cables can be inserted into the terminals and fixed alternately.

[0073] The wire holder 13 can be integrally formed with the second box body 112, or connected to the second box body 112 in other ways. For example, the wire holder 13 can be connected to the second box body 112 by bonding, welding, clamping, or fastening with fasteners such as screws and bolts.

[0074] for Figure 4 The second box body 112 shown has a third shell 1121 and a fourth shell 1122 , and the wire fixing seat 13 is arranged in the fourth shell 1122 . In other embodiments, the wire fixing seat 13 can also be arranged in the third shell 1121 .

[0075] Another embodiment of the present application further provides a head assembly. Figures 1 to 3 The head assembly includes a water receiving tray 30, a cover shell 20 and the electronic control box 10 provided in any embodiment of the present application.

[0076] The cover 20 is disposed on one side of the water receiving tray 30 . The cover 20 includes a shell body 21 and a shell cover 22 . The shell cover 22 is disposed on a side of the shell body 21 facing away from the water receiving tray 30 .

[0077] The housing 20 has an air inlet 20a and an air outlet 20b. Figure 1 The air inlet 20a and the air outlet 20b of the housing 20 are both provided on the housing body 21. In other embodiments, at least one of the air inlet 20a and the air outlet 20b may also be provided on the housing cover 22.

[0078] The electrical control box 10 is arranged in the cover 20, and the second box body 112 is located on the side of the first box body 111 facing away from the water receiving tray 30. That is, the second box body 112 is set close to the shell cover 22. After the second box body 112 is closed, the component surface of the electrical control board 12 faces the water receiving tray 30, which is equivalent to the electrical control box 10 being installed roughly horizontally in the cover 20.

[0079] See also Figures 1 to 3 The head assembly also houses a heat exchanger 40, a compressor 50, and a wind turbine within the housing 20. When in operation, the wind turbine drives air from the outside into the housing 20 through the air inlet 20a. The air then exchanges heat at the heat exchanger 40 before exiting through the air outlet 20b. The water tray 30 collects condensed water that drips from the heat exchanger 40.

[0080] For example, see Figure 3 、 Figure 8 and Figure 9 The electric control box 10 may be disposed on the upper side of the compressor 50 , that is, the electric control box 10 may be disposed between the compressor 50 and the housing cover 22 of the casing 20 .

[0081] Figure 1 The housing cover 22 is detachably connected to the housing body 21. After the housing cover 22 is removed, the second box body 112 can be opened without removing the housing body 21, thereby facilitating maintenance of the electric control box 10. In other embodiments, regardless of whether the housing cover 22 is detachably connected to the housing body 21, the second box body 112 can be opened after the entire housing 20 is disassembled.

[0082] Another embodiment of the present application further provides a heat pump water heater, which includes a water tank assembly and a head assembly provided by any embodiment of the present application, and the head assembly is arranged on the water tank assembly, that is, this heat pump water heater is an integrated heat pump water heater.

[0083] 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.

[0084] 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.

[0085] The electric control box 10 of the embodiment of the present application is provided with a box body assembly 11 having a first box body 111 and a second box body 112, and a wire fixing seat 13 located outside the box body assembly 11 is provided on one side of the second box body 112 where multiple wire passing openings 112a are provided. The wire fixing seat 13 can be used to reliably and orderly fix the cables electrically connected to the electric control board 12, thereby better preventing the cables from loosening and further improving the convenience of cable management.

[0086] It should be noted that the electrical control box 10 in the head assembly is not limited to setting the second box body 112 on the side of the first box body 111 away from the water receiving tray 30. For example, in other embodiments, the second box body 112 can also be located on the side of the first box body 111 close to the shell body 21, which is equivalent to the electrical control box 10 being able to be vertically installed in the cover 20.

[0087] In addition, 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.

[0088] In one embodiment, please refer to Figure 8 The second box body 112 can be rotatably connected to the first box body 111, and the rotation axis of the second box body 112 is located on a side of the second box body 112 away from the wire fixing seat 13 along the second direction.

[0089] In other words, the second box body 112 is opened or closed by rotating. The rotating connection allows the second box body 112 to remain connected to the first box body 111 after it is opened, thereby facilitating the operator to manage cables. The advantage of the rotation axis of the second box body 112 being located on the side of the second box body 112 that is away from the cable holder 13 along the second direction is that when the second box body 112 is opened, the cable holder 13 is located on the side of the second box body 112 that is away from the first box body 111, and the first box body 111 does not obstruct the operator's hands, thereby improving the convenience of the operator in managing cables.

[0090] In other embodiments, the rotation axis of the second box body 112 may also be located on other sides of the second box body 112, or the second box body 112 may not be rotationally connected to the first box body 111. For example, the second box body 112 and the first box body 111 may adopt a split structure, that is, after the second box body 112 is opened, the second box body 112 is separated from the first box body 111.

[0091] In one embodiment, please refer to Figures 5 to 10 The wire fixing seat 13 can include a seat body 131 and a first wire fixing structure 132, a second wire fixing structure 133 and a third wire fixing structure 134 arranged on the seat body 131. The first wire fixing structure 132, the second wire fixing structure 133 and the third wire fixing structure 134 respectively correspond to different wire passing openings 112a.

[0092] That is, there are at least three wire-passing openings 112a, and the cables passing through different wire-passing openings 112a can be fixed respectively by the first wire-fixing structure 132, the second wire-fixing structure 133, and the third wire-fixing structure 134. This can facilitate orderly fixing of the cables on the wire-fixing base 13.

[0093] In addition, the first wire fixing structure 132, the second wire fixing structure 133 and the third wire fixing structure 134 can also be used to separate the high-current cables and the low-current cables. For example, the first wire fixing structure 132 and the second wire fixing structure 133 can be used to fix the high-current cables, and the second wire fixing structure 133 can be used to fix the low-current cables, thereby achieving the separation of the high-current cables and the low-current cables.

[0094] The specific position relationship of the first fixing structure 132, the second fixing structure 133 and the third fixing structure 134 is not limited, but in order to facilitate the arrangement of the first fixing structure 132, the second fixing structure 133 and the third fixing structure 134 on the base 131, for example, refer to Figure 5 The first fixing structure 132 and the second fixing structure 133 can be spaced apart and arranged on opposite sides of the base 131 along the third direction, and the third fixing structure 134 can be arranged on a side of the second fixing structure 133 away from the second box body 112 along the first direction.

[0095] Please continue reading Figure 10 , the plurality of line-passing openings 112a may be distributed in three line-passing areas arranged along the third direction ( Figure 10 Each dotted box represents a cross-line area).

[0096] Figure 10 Each of the three line-passing areas has at least two line-passing openings 112a. For example, among the three line-passing areas, the line-passing areas on opposite sides along the third direction each have two line-passing openings 112a, while the line-passing area in the middle has four line-passing openings 112a. It is understood that the number of line-passing openings 112a in each line-passing area can be adjusted according to actual needs, and each line-passing area only needs to have at least one line-passing opening 112a.

[0097] See also Figure 10 For the second box body 112 with at least two wire-passing openings 112a in the same area, the distance between two adjacent wire-passing areas along the third direction can be greater than the distance between two adjacent wire-passing openings 112a in the same wire-passing area along the third direction, so that the operator can clearly distinguish the three wire-passing areas.

[0098] See also Figure 10The third wire-fixing structure 134 may correspond to the middle wire-passing area among the three wire-passing areas, and the first wire-fixing structure 132 and the second wire-fixing structure 133 may correspond to the wire-passing areas on the same side, respectively.

[0099] That is to say, the cables passing through the wire passing opening 112a in the same wire passing area are fixed by the same wire fixing structure among the first wire fixing structure 132, the second wire fixing structure 133 and the third wire fixing structure 134, while the cables passing through the wire passing opening 112a in different wire passing areas are fixed by different wire fixing structures among the first wire fixing structure 132, the second wire fixing structure 133 and the third wire fixing structure 134.

[0100] The first wire-fixing structure 132 and the second wire-fixing structure 133 respectively correspond to the wire-passing areas on the same side, which can facilitate the cables fixed by the first wire-fixing structure 132 and the second wire-fixing structure 133 to be routed separately and almost not be intertwined with each other. The third wire-fixing structure 134 corresponds to the wire-passing area located in the middle, which can also facilitate the cables fixed by the third wire-fixing structure 134 to be routed separately and almost not be intertwined with the cables fixed by the first wire-fixing structure 132 and / or the second wire-fixing structure 133.

[0101] The specific structural forms of the first wire fixing structure 132, the second wire fixing structure 133 and the third wire fixing structure 134 are not limited. For example, please refer to Figures 5 to 7 、 Figure 10 The first cable securing structure 132 can be provided with a first cable tie 1321. The number of first cable ties 1321 can be one or more. The first cable tie 1321 has a first cable passage 1321a and a first opening 1321b communicating with the first cable passage 1321a. The first cable passage 1321a extends through two opposite sides of the first cable tie 1321 along the third direction. The first opening 1321b is located on one side of the first cable passage 1321a along the first direction and faces two opposite directions relative to the electronic control board 12.

[0102] The first cable passage 1321 a is used to accommodate cables, and the first opening 1321 b is used to allow cables to enter the first cable passage 1321 a.

[0103] The orientation of the electric control board 12 described in this embodiment of the application refers to the direction in which the component surface of the electric control board 12 faces the first case 111 when the second case 112 is closed. The orientation of the first opening 1321b of the first cable tie 1321 is opposite to the direction in which the component surface of the electric control board 12 faces the first case 111. This arrangement enables the first cable tie 1321 to provide a certain stop for the cable, preventing it from coming out of the side of the second case 112 where the electric control board 12 is located.

[0104] Please continue reading Figures 5 to 7 、 Figure 10 The first wire-fixing structure 132 may also be provided with a fourth wire tie 1322, which is located on a side of the first wire tie 1321 along the third direction that is closer to the second wire-fixing structure 133. The fourth wire tie 1322 has a fourth wire-passing channel 1322a and a fourth opening 1322b communicating with the fourth wire-passing channel 1322a. The fourth wire-passing channel 1322a extends through two opposite sides of the fourth wire tie 1322 along the first direction and communicates with the first wire-passing channel 1321a. The fourth opening 1322b is located on a side of the fourth wire-passing channel 1322a that faces away from the second housing 112.

[0105] Figures 5 to 7 、 Figure 10 The fourth thread tie 1322 is shown as being integrally connected to the first thread tie 1321 . In other embodiments, the fourth thread tie 1322 may also be spaced apart from the first thread tie 1321 .

[0106] The fourth cable passage 1322a is used to accommodate cables, and the fourth opening 1322b is used to allow cables to enter the fourth cable passage 1322a.

[0107] The fourth cable passage 1322a is connected to the first cable passage 1321a, which means that the same cable is located in both the first cable passage 1321a and the fourth cable passage 1322a. The fourth cable passage 1322a extends through two opposite sides of the fourth cable tie 1322 along the first direction to allow the cable to exit along the first direction from the side of the second housing 112 where the electronic control board 12 is located.

[0108] For example, see Figures 5 to 7 、 Figure 10 The second cable fixing structure 133 may be provided with a second cable tie 1331. The number of second cable tie 1331 may be one or more. The second cable tie 1331 has a second cable passage 1331a and a second opening 1331b communicating with the second cable passage 1331a. The second cable passage 1331a extends through two opposite sides of the second cable tie 1331 along the third direction. The second opening 1331b is located on one side of the second cable passage 1331a along the first direction and faces two opposite directions relative to the electronic control board 12.

[0109] The second cable passage 1331 a is used to accommodate cables, and the second opening 1331 b is used to allow cables to enter the second cable passage 1331 a.

[0110] The structure of the second thread tie 1331 is similar to that of the first thread tie 1321 , and the direction of the second opening 1331 b of the second thread tie 1331 is the same as the direction of the first opening 1321 b of the first thread tie 1321 .

[0111] The second cable clip 1331 can also play a certain stopping role on the cable to prevent the cable from falling out from the side of the second box body 112 where the electronic control board 12 is provided.

[0112] In addition, the cable fixed to the second cable clip 1331 may also be led out along the first direction from the side of the second box body 112 where the electric control board 12 is provided.

[0113] Please continue reading Figures 5 to 7 、 Figure 10 The second wire fixing structure 133 may further be provided with a magnetic ring mounting seat 1332 , and the magnetic ring mounting seat 1332 is provided on a side of the second wire buckle 1331 close to the first wire fixing structure 132 along the third direction.

[0114] The magnetic ring mounting seat 1332 can be used to install the magnetic ring. Taking the head assembly as an example, since the cable of the compressor 50 generally has a magnetic ring, and the magnetic ring is relatively heavy, the magnetic ring may also cause the cable of the compressor 50 to loosen from the electronic control board 12 under the action of its own gravity. Therefore, the magnetic ring of the compressor 50 can be installed on the magnetic ring mounting seat 1332 to support the magnetic ring through the magnetic ring mounting seat 1332 to reduce the risk of the cable of the compressor 50 loosening from the electronic control board 12.

[0115] For example, see Figures 5 to 7 、 Figure 10 The third cable securing structure 134 may be provided with a third cable tie 1341. The number of third cable tie 1341 may be one or more. The third cable tie 1341 has a third cable passage 1341a and a third opening 1341b communicating with the third cable passage 1341a. The third cable passage 1341a extends through two opposite sides of the third cable tie 1341 along the third direction. The third opening 1341b is located on one side of the third cable passage 1341a along the first direction and faces two opposite directions relative to the electronic control board 12.

[0116] The third cable passage 1341 a is used to accommodate cables, and the third opening 1341 b is used to allow cables to enter the third cable passage 1341 a.

[0117] The structure of the third thread tie 1341 is similar to that of the first thread tie 1321 , and the orientation of the third opening 1341 b of the third thread tie 1341 is the same as that of the third opening 1341 b of the first thread tie 1321 .

[0118] The third cable clip 1341 can also play a certain stopping role on the cable to prevent the cable from falling out from the side of the second box body 112 where the electronic control board 12 is provided.

[0119] See also Figure 8 and Figure 10For the electrical control box 10 that is arranged in the head assembly and the second box body 112 is located on the side of the first box body 111 away from the water receiving tray 30, the second wire fixing structure 133 and the third wire fixing structure 134 can be located on the side of the second box body 112 close to the heat exchanger 40, and one end of the third wire passing channel 1341a of the third wire buckle 1341 can face the heat exchanger 40, that is, the cable fixed to the third wire buckle 1341 can also be connected to the heat exchanger 40.

[0120] Please continue reading Figure 7 For the third wire fixing structure 134 having multiple third wire buckles 1341, the multiple third wire buckles 1341 can be arranged at intervals along the third direction, and the distance between each third wire buckle 1341 and the second box body 112 along the first direction can also gradually increase in the direction away from the first wire fixing structure 132.

[0121] The distance between the third cable tie 1341 and the second housing 112 along the first direction is equivalent to the distance between the projection of the third cable tie 1341 and the projection of the second housing 112 along the first direction, as measured on a projection plane perpendicular to the second direction. In other words, the third cable ties 1341 can be arranged in a stepped pattern with height differences along the third direction. Furthermore, among all the third cable ties 1341, the farther the third cable tie 1341 is from the first cable securing structure 132, the greater the distance between the third cable tie 1341 and the second housing 112 along the first direction.

[0122] This arrangement is helpful for arranging cables with long routing paths on the cable holder 13, for example, Figure 10 For the third wire fixing structure 134 arranged on the side of the second wire fixing structure 133 away from the second box body 112 along the first direction, the routing path of the cable fixed by it on the wire fixing seat 13 is longer than the routing paths of the cables fixed by the first wire fixing structure 132 and the second wire fixing structure 133 on the wire fixing seat 13. Therefore, multiple third wire buckles 1341 are provided, and the distance between each third wire buckle 1341 and the second box body 112 along the first direction gradually increases toward the direction away from the first wire fixing structure 132, which can facilitate fixing these cables with longer routing paths at multiple positions to better prevent these cables from loosening.

[0123] Further, see Figures 5 to 7 、 Figure 10 The third wire fixing structure 134 can also set a fifth wire buckle 1342 between the two third wire buckles 1341, and the fifth wire passing channel 1342a passes through the opposite sides of the fifth wire buckle 1342 along the third direction. The fifth opening 1342b is located on one side of the fifth wire passing channel 1342a along the first direction and faces the same direction as the electronic control board 12.

[0124] The fifth cable passage 1342a of the fifth cable tie 1342 and the third cable passage 1341a of the third cable tie 1341 jointly accommodate the same cable, and the fifth opening 1342b is used for allowing the cable to enter the fifth cable passage 1342a.

[0125] The fifth opening 1342 b faces the same direction as the electric control board 12 . That is, the direction of the fifth opening 1342 b is opposite to the direction of the third opening 1341 b of the third cable tie 1341 .

[0126] The fifth cable buckle 1342 is disposed between the two third cable buckles 1341 and can function as a reverse stop for the cable, thereby effectively preventing the cable from falling out of the third opening 1341 b of the third cable buckle 1341 .

[0127] In one embodiment, please refer to Figures 5 to 7 、 Figure 10 For a cable holder 13 in which the first and second cable fixing structures 132, 133 are spaced apart on opposite sides of the base 131 along the third direction, and the third cable fixing structure 134 is disposed on a side of the second cable fixing structure 133 facing away from the second housing 112 along the first direction, the cable holder 13 may further include a first blocking piece 135 on the base 131. The first blocking piece 135 is located on a side of the first cable fixing structure 132 facing away from the first cable fixing structure 132 along the third direction, and is located outside the cable passage 112a closest to the first blocking piece 135. The first blocking piece 135 extends along the second direction away from the second housing 112, and at least a portion of the first blocking piece 135 is offset toward the first cable fixing structure 132.

[0128] That is, some parts of the first baffle 135 are located on the side of other parts close to the first wire fixing structure 132. The first baffle 135 can stop the cables closer to the first baffle 135, thereby better preventing the cables from protruding outward from the wire passage 112a closest to the first baffle 135.

[0129] See also Figures 5 to 7 、 Figure 10 The wire fixing seat 13 may also be provided with a second blocking piece 136 on the seat body 131. The second blocking piece 136 is located between the first wire fixing structure 132 and the third wire fixing structure 134 and is spaced apart from the second box body 112 along the second direction.

[0130] The gap between the second baffle 136 and the second box body 112 is used for cables to pass through, and the second baffle 136 can serve as a stop for at least part of the cables fixed to the third wire fixing structure 134, so as to better prevent the cables from protruding from the side of the base body 131 away from the second box body 112 along the second direction to the outside of the base body 131.

[0131] See also Figure 6 、 Figure 7 and Figure 10 The fixed wire seat 13 can further be provided with a sixth wire buckle 137 on the seat body 131, the sixth wire buckle 137 being located between the first fixed wire structure 132 and the third fixed wire structure 134. The sixth wire buckle 137 has a sixth wire passing channel 137a penetrating through the sixth wire buckle 137 along opposite sides in the third direction and a sixth opening 137b in communication with the sixth wire passing channel 137a, the sixth opening 137b being located at one side of the sixth wire passing channel 137a in the first direction and facing two opposite directions of the electric control panel 12 respectively.

[0132] The sixth wire passing channel 137a is used for accommodating at least part of the cable fixed to the third fixed wire structure 134, and the sixth opening 137b is used for allowing the cable to enter the sixth wire passing channel 137a.

[0133] The sixth wire buckle 137 has a structure similar to that of the first wire buckle 1321, and the sixth opening 137b of the sixth wire buckle 137 faces the same direction as the sixth opening 137b of the first wire buckle 1321.

[0134] The sixth wire buckle 137 can also play a certain stopping role on the cable to better avoid the cable from being lifted up at the part between the third fixed wire structure 134 and the second box body 112.

[0135] In an embodiment, referring to Figures 11 to 18 The electric control box 10 can further be provided with a waterproof cover 14 and a water blocking boss 15, the water blocking boss 15 being arranged outside the first box body 111 and located at the same side of the fixed wire seat 13 in the box body assembly 11, and the waterproof cover 14 being arranged on the fixed wire seat 13 and detachably connected with the water blocking boss 15.

[0136] It can be understood that the waterproof cover 14 will not block the cable, that is, an avoiding opening will be arranged between the waterproof cover 14 or the waterproof cover 14 and the water blocking boss 15 to allow the cable to pass through.

[0137] The detachable connection between the waterproof cover 14 and the water blocking boss 15 is not limited, and exemplarily, the waterproof cover 14 and the water blocking boss 15 can be fastened and connected, for example, referring to Figure 14 The waterproof cover 14 can be provided with a first fastening hole 14a, and the water blocking boss 15 can be provided with a mounting column 15a having a second fastening hole 15b, a fastener such as a screw being arranged in the first fastening hole 14a and the second fastening hole 15b to realize the fastened connection between the waterproof cover 14 and the water blocking boss 15.

[0138] In other embodiments, the waterproof cover 14 can be provided with the mounting column 15a having the second fastening hole 15b, and the water blocking boss 15 can be provided with the first fastening hole 14a.

[0139] For example, the waterproof cover 14 and the water retaining boss 15 can also be snap-fitted, for example, see Figures 15 to 18 The waterproof cover 14 can be provided with a card slot 14b, and the card slot 14b has a notch 14c on one side along the third direction. The water-blocking boss 15 is provided with a buckle 15c, and the buckle 15c is snapped into the card slot 14b from the notch 14c. That is to say, the waterproof cover 14 can be pushed along the third direction so that the buckle 15c is snapped into the card slot 14b from the notch 14c. When the waterproof cover 14 needs to be removed, it only needs to be pulled in the opposite direction along the third direction so that the buckle 15c can be disengaged from the notch 14c.

[0140] In other embodiments, the waterproof cover 14 may be provided with a buckle 15 c and the water-blocking boss 15 may be provided with a slot 14 b.

[0141] In other embodiments, the waterproof cover 14 may be both snap-fitted with the water-blocking boss 15 and also be fastened to the water-blocking boss 15 .

[0142] Because some heat pump water heaters are installed outdoors, rainwater and other water flows may enter the head assembly through the air inlet 20a and air outlet 20b of the head assembly. Although a seal 16 is generally provided at the wire opening 112a of the electric control box 10 for sealing, when there is heavy rain, there is still a risk that rainwater will seep into the accommodating chamber 11a through the wire opening 112a or the sealing groove of the seal 16. Therefore, the provision of the waterproof cover 14 and the water-blocking boss 15 can effectively prevent rainwater and other water flows from flowing onto the wire fixing seat 13 and then seeping into the accommodating chamber 11a through the wire opening 112a or the sealing groove of the seal 16, thereby damaging the electric control board 12.
