[0051] In the related art, the display is generally mounted on a circuit board, and the circuit board is mounted on a control box of the electric water heater. The control box is usually mounted on the outer shell of the electric water heater. A regional hole is opened on the control box to expose the display information on the display element, so the circuit board needs to be fixed relative to the control box.

[0052] However, during the use of the water heater, the circuit board is a consumable part and needs to be replaced when a circuit board fails. In the related art, the circuit board is fixed together with the control box, which is not convenient for disassembly and replacement of the circuit board.

[0053] In order to solve the above problems, the present application provides a water heater 100 .

[0054] The water heater 100 provided in the present application may be an electric water heater 100, a gas water heater 100, a solar water heater 100, a heat pump water heater 100, etc.

[0055] like Figure 1 As shown, Figure 1 This is one of the structural schematic diagrams of a water heater 100 provided in an embodiment of the present application. The water heater 100 provided in the present application includes a box 1. The box 1 provides a space for storing water, and the present application does not specifically limit the shape of the box 1.

[0056] like Figure 2 As shown, Figure 2 The second structural schematic diagram of a water heater 100 provided in an embodiment of the present application. The water heater 100 provided in the present application includes a control box 2. The control box 2 is located outside the housing 1, and forms an installation cavity 21 with the housing 1. It can be understood that the control box 2 and the housing 1 form the installation cavity 21, that is, the control box 2 and the housing 1 have a common installation surface, and the installation surface is connected to the installation cavity 21.

[0057] The control box 2 is detachably connected to the box body 1. The control box 2 is connected to the box body 1 by at least one of a snap connection, a plug connection, a thread connection, and the like.

[0058] like Figure 3 As shown, Figure 3 This is one of the structural schematic diagrams of a control box 2 provided in an embodiment of the present application. The control box 2 is also provided with a mounting opening 22 , which is communicated with the mounting cavity 21 .

[0059] like Figure 4 As shown, Figure 4 This is one of the structural schematic diagrams of a circuit board 3 and related parts provided in an embodiment of the present application. It should be noted that the related parts are other devices installed on the circuit board 3.

[0060] Combination Figure 2 and Figure 4 The water heater 100 provided in this application (see Figure 2 ) also includes a display 4. The display 4 can display images, text, numbers or other information related to the water heater 100.

[0061] like Figure 5 As shown, Figure 5 This is one of the schematic diagrams of the position of the display 4 provided in an embodiment of the present application. Exemplarily, the display 4 is inserted into the mounting opening 22, and the information displayed by the display 4 can be exposed through the mounting opening 22. The display end of the display 4 is closer to the opening of the mounting opening 22, reducing the blind spot of the display 4 due to the obstruction of the control box 2.

[0062] like Figure 6 As shown, Figure 6 The second schematic diagram of the position of the display 4 provided in an embodiment of the present application. Exemplarily, the display 4 is disposed in the mounting cavity 21, and the information displayed by the display 4 can be exposed through the mounting opening 22. The display 4 is further away from the mounting opening 22, which can prevent water from falling on the display and causing damage to the display.

[0063] Exemplarily, at least a portion of the display 4 is located in the mounting opening 22 , and at least a portion of the display 4 is located in the mounting cavity 21 .

[0064] For easier understanding, please combine Figure 7 and Figure 8 As shown, Figure 7 This is one of the schematic diagrams of the installation structure of the circuit board 3 and the control box 2 provided in one embodiment of the present application. Figure 8 This is a second schematic diagram of the installation structure of the circuit board 3 and the control box 2 provided in an embodiment of the present application.

[0065] The water heater 100 provided in this application (see Figure 2 ) further includes a circuit board 3. The circuit board 3 is arranged in the installation cavity 21 and located at the installation opening 22, and the display 4 is connected to the circuit board 3.

[0066] The size of the circuit board 3 can be larger than the size of the installation opening 22, smaller than the size of the installation opening 22, or equal to the size of the installation opening 22. There is no specific restriction on the size of the circuit board 3 here, which can be determined according to actual usage.

[0067] like Fig. 9 and Fig.10 As shown, Fig. 9 The second structural diagram of the control box 2 provided in one embodiment of the present application is as follows: Fig.10 An embodiment of the present application provides Fig. 9 The enlarged schematic diagram of A in the middle. Figure 4 The control box 2 is also formed with a socket 23 .

[0068] Recombination Figure 4 , Fig. 9 and Fig.10 The circuit board 3 has a first end 31 and a second end 32 which are opposite to each other. The first end 31 is plugged into the socket 23 , and the second end 32 is detachably connected to the control box 2 .

[0069] When the circuit board 3 needs to be removed, it is only necessary to disassemble the circuit board 3 from the control box 2 through the second end 32, that is, to release the limit on the circuit board 3, and then pull the first end 31 of the circuit board 3 out of the socket 23 to remove the circuit board 3. When installing the circuit board 3, the first end 31 of the circuit board 3 is inserted into the socket 23, and then connected to the control box 2 through the second end 32, so as to limit and fix the circuit board 3. In this way, when disassembling and installing the circuit board 3, the operation is simple and convenient.

[0070] Continue to see Figure 8 , Fig. 9 and Fig.10 In some embodiments, the control box 2 includes a main body 24. The main body 24 and the box body 1 (see Figure 1 ) surrounds a mounting cavity 21, and a mounting opening 22 is disposed on the main body 24.

[0071] In some embodiments, the control box 2 includes a first limiting portion 25 connected to the main body 24 , located on a side of the circuit board 3 away from the installation cavity 21 , and in contact with a surface of the circuit board 3 away from the installation cavity 21 .

[0072] When the circuit board 3 is installed and inserted into the socket 23 , the first limiting portion 25 has a limiting effect on the circuit board 3 . When the first limiting portion 25 contacts the circuit board 3 , it limits the circuit board 3 from moving away from the installation cavity 21 , preventing the circuit board 3 from escaping from the installation opening 22 .

[0073] Exemplarily, the first limiting portion 25 is located in the installation opening 22 and connected to the wall of the installation opening 22 . The first limiting portion 25 is in contact with the circuit board 3 on one side close to the circuit board 3 . At this time, the display 4 connected to the circuit board 3 is inserted into the installation opening 22 .

[0074] Exemplarily, the first limiting portion 25 is located in the installation cavity 21 and connected to the main body 24 . The first limiting portion 25 is in contact with the circuit board 3 on one side close to the circuit board 3 . At this time, at least a portion of the display 4 is located in the installation cavity 21 .

[0075] In some embodiments, there are multiple first limiting portions 25 , which are spaced apart along a first direction X. The first direction X is perpendicular to the arrangement direction of the first end 31 and the second end 32 , and perpendicular to the thickness direction of the circuit board 3 .

[0076] When the plurality of first limiting portions 25 limit the circuit board 3, the limiting effect is stable. When the plurality of first limiting portions 25 limit the circuit board 3, the force of the circuit board 3 on the first limiting portions 25 is evenly distributed on the plurality of first limiting portions 25, and the force is evenly applied, thereby reducing the situation where the circuit board 3 is damaged due to uneven force.

[0077] A plurality of first limiting portions 25 are provided, and when the circuit board 3 is inserted into the socket 23, not all of the first limiting portions 25 need to contact the circuit board 3. However, a plurality of first limiting portions 25 can adapt to the insertion of circuit boards 3 of different sizes into the socket 23, and when limiting the circuit board 3, the control box 2 can adapt to circuit boards 3 of different sizes, thereby improving the versatility of the control box 2.

[0078] Exemplarily, the spacing distances of the plurality of first position limiting portions 25 along the first direction X are equal, and the spacing distances of the plurality of first position limiting portions 25 along the first direction X may also be unequal, which can be set according to actual conditions.

[0079] like Fig.11 As shown, Fig.11 The third structural diagram of the control box provided by an embodiment of the present application. In some embodiments, the number of the first limiting portion 25 is one, and the first limiting portion 25 extends along the first direction X. Only one first limiting portion 25 is provided, which can fix the circuit board 3 and save materials, thereby reducing costs.

[0080] like Fig.12 As shown, Fig.12 This is one of the structural schematic diagrams of the first limit portion provided in an embodiment of the present application. In some embodiments, the first limit portion 25 is close to the circuit board 3 (such as Figure 8 The surface of the circuit board 3 includes a limit surface 251. When the circuit board 3 is inserted into the socket 23 (as shown in FIG. Fig.11When the position limiting surface 251 contacts the circuit board 3, the position limiting surface 251 includes a first side 252 and a second side 253 opposite to each other. The first side 252 and the main body 24 (as shown in FIG. Fig.10 as shown) connection.

[0081] In some embodiments, the surface of the first limiting portion 25 close to the circuit board 3 includes a guide surface 254. The guide surface 254 is located on the side of the second edge 253 away from the first edge 252, and is connected to the second edge 253. Along the arrangement direction of the guide surface 254 and the limiting surface 251, and from the first edge 252 to the second edge 253, the distance between the guide surface 254 and the circuit board 3 gradually increases.

[0082] The guide surface 254 includes a third side 255 and a fourth side 256 opposite to each other. The third side 255 is connected to the limiting surface 251. The third side 255 of the guide surface 254 is the second side 253 of the limiting surface 251. The distance between the fourth side 256 and the circuit board 3 is greater than the distance between the third side 255 and the circuit board 3.

[0083] When the circuit board 3 needs to be inserted into the socket 23, the socket 23 of the fourth side 256 is larger than the thickness of the circuit board 3, which facilitates the insertion of the circuit board 3. The friction between the circuit board 3 and the first limiting portion 25 is reduced, and the risk of damage to the circuit board 3 is reduced.

[0084] At the same time, when the circuit board 3 is plugged into the socket 23 at a certain angle, the edge of the circuit board 3 abuts against the guide surface 254, and the guide surface 254 guides the insertion of the circuit board 3 into the socket 23, so that the circuit board 3 slides along the guide surface 254 and then contacts the limit surface 251. In this way, the circuit board 3 does not need to be perpendicular to the socket 23 and can be inserted, which is convenient for maintenance personnel to operate.

[0085] Exemplarily, the guide surface 254 is a plane.

[0086] like Fig.13 As shown, Fig.13 FIG. 2 is a schematic diagram of the structure of the first limit portion provided by an embodiment of the present application. For example, the guide surface 254 is an arc surface, and the arc surface can be close to the circuit board 3 (see Figure 8 ), and the arc surface may also protrude in a direction away from the circuit board 3.

[0087] Continue to see Fig.10 In some embodiments, the control box 2 includes a second limit portion 26. The second limit portion 26 is connected to the main body 24, and the second limit portion 26 is at least partially located on the circuit board 3 (see Figure 8 ) is located at a side close to the mounting cavity 21 and in contact with a surface of the circuit board 3 close to the mounting cavity 21. A socket 23 is formed between the first limiting portion 25 and the second limiting portion 26.

[0088] When the circuit board 3 is installed and inserted into the socket 23 , the second limiting portion 26 has a limiting effect on the circuit board 3 . When the second limiting portion 26 contacts the circuit board 3 , the circuit board 3 is restricted from moving toward the installation cavity 21 .

[0089] When the first limiting portion 25 and the second limiting portion 26 are provided at the same time, the circuit board 3 can be limited in the depth direction of the installation opening 22 , thereby reducing the distance of the circuit board 3 from or close to the installation cavity 21 and improving the stability of the circuit board 3 .

[0090] In some embodiments, there are multiple second limiting portions 26, and the multiple second limiting portions 26 are arranged at intervals along the first direction X. The first direction X is parallel to the first end 31 (see Figure 8 ) and the second end 32 (see Figure 8 ) is arranged in a direction perpendicular to the direction of the circuit board 3 and is perpendicular to the thickness direction of the circuit board 3.

[0091] When the plurality of second limiting portions 26 limit the circuit board 3, the limiting effect is stable. When the plurality of second limiting portions 26 limit the circuit board 3, the force of the circuit board 3 on the second limiting portions 26 is evenly distributed on the plurality of second limiting portions 26, and the force is evenly applied, thereby reducing the situation where the circuit board 3 is damaged due to uneven force.

[0092] A plurality of second limiting portions 26 are provided, and when the circuit board 3 is inserted into the socket 23, not all of the second limiting portions 26 need to contact the circuit board 3. However, a plurality of second limiting portions 26 can be provided to limit the circuit board 3 when circuit boards 3 of different sizes are inserted into the socket 23, so that the control box 2 can adapt to circuit boards 3 of different sizes, thereby improving the versatility of the control box 2.

[0093] Exemplarily, the spacing distances between the plurality of second position limiting portions 26 along the first direction X are equal, and the spacing distances between the plurality of second position limiting portions 26 along the first direction X may also be unequal, which can be set according to actual conditions.

[0094] Continue to see Fig.10 In some embodiments, one second limiting portion 26 corresponds to two first limiting portions 25 . In the first direction X, the second limiting portion 26 is located between the corresponding two first limiting portions 25 .

[0095] Thus, a second limiting portion 26 and two first limiting portions 25 form a fixed point. At this time, the socket 23 is the space between the second limiting portion 26 and the two first limiting portions 25. Figure 8 ) is inserted into the socket 23, the circuit board 3 is limited by the second limiting portion 26 and the two first limiting portions 25.

[0096] One second limiting portion 26 and two first limiting portions 25 form a stable limiting structure, which can reduce the phenomenon that the circuit board 3 tilts toward the mounting opening 22 due to unbalanced fixing.

[0097] Continue to see Figure 4 In some embodiments, the second end 32 of the circuit board 3 is provided with an avoidance hole 33 .

[0098] like Figure 8 and Fig.14 As shown, Fig.14 An embodiment of the present application provides Fig. 9 In some embodiments, the control box 2 further includes a connecting portion 27. The connecting portion 27 is connected to the main body 24, and is located on a side of the circuit board 3 away from the installation cavity 21, and is in contact with a surface of the circuit board 3 away from the installation cavity 21, and a connecting hole 271 is provided on the connecting portion 27. The connecting hole 271 is used to connect the circuit board 3.

[0099] Exemplarily, the connection portion 27 is located at the installation opening 22. The side of the connection portion 27 facing the installation cavity 21 contacts the circuit board 3, and the connection hole 271 is aligned with the avoidance hole 33 (see Figure 4 ) position.

[0100] Exemplarily, the connection portion 27 is located in the mounting cavity 21 and connected to the main body 24. One side of the connection portion 27 contacts the circuit board 3. The connection hole 271 is connected to the avoidance hole 33 (see Figure 4 ) position.

[0116] At the same time, panel 7 corresponds to display 4 (see Figure 4 ) is a transparent area, and the user can understand the operating status, parameter changes, etc. of the water heater 100 through the panel 7 and operate and control the operating parameters of the water heater 100.

[0117] The panel 7 covers the installation cavity 21 to prevent water from directly falling onto the circuit board 3 through the installation opening 22 , thereby protecting the circuit board 3 and reducing the risk of damage to the circuit board 3 .

[0118] like Figure 3 As shown, in some embodiments, the control box 2 is provided with a plurality of snap-in holes 28 .

[0119] Combination Figure 2 and Fig.16 As shown, the panel 7 includes a main body 71 and a plurality of buckles 72. The main body 71 covers the mounting opening 22 and contacts the control box 2. The plurality of buckles 72 are connected to the main body 71 and are arranged at intervals along the circumference of the mounting opening 22. The buckles 72 are located on a side of the main body 71 close to the control box 2, and one buckle 72 is engaged with one engaging hole 28.

[0120] The buckle 72 enters the clamping hole 28 and is clamped with the clamping hole 28, thereby fixing the panel 7 to the control box 2. Through the buckle 72 and the clamping hole 28, the panel 7 can be quickly disassembled and assembled, which is convenient for maintenance personnel to operate.

[0121] In some embodiments, the panel 7 is fixed to the control box 2 by gluing or magnetically connecting. Specifically, the control panel 7 is fixed to a side of the control box 2 away from the circuit board 3 by gluing or magnetically connecting.

[0122] Combination Figure 2 and Fig.16 As shown, in some embodiments, the panel 7 includes a positioning column 73, which is connected to the body 71 and is located on a side of the body 71 close to the control box 2. Correspondingly, the control box 2 is provided with a positioning hole 29, which corresponds to the position of the positioning column 73, and the positioning column 73 can be inserted into the positioning hole 29.

[0123] When the panel 7 needs to be installed, the alignment state of the panel 7 and the control box 2 can be quickly found through the positioning columns 73 and the positioning holes 29, thereby speeding up the installation of the panel 7.
