[0029] The following is a further detailed description of the implementation of the present application in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present application but cannot be used to limit the scope of the present application.
[0030] The various specific technical features and embodiments described in the specific implementation methods can be combined in any suitable manner without contradiction. For example, different implementation methods can be formed by combining different specific technical features / embodiments. In order to avoid unnecessary repetition, the various possible combinations of the specific technical features / embodiments in this application are no longer described separately. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance. The application is further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0031] In the related art, the cable needs to enter the housing to facilitate the connection with the control board, etc., and the connection between the cable and the control board is located in the housing. When installing or repairing the cable, the housing needs to be disassembled to repair the connection between the cable and the control board, which is complicated.
[0032] See also Figures 1 to 5 According to a first aspect of an embodiment of the present application, a wall-mounted boiler 100 is provided, comprising a housing 10 and a control assembly 20. The housing 10 is formed with a receiving cavity and a wiring port 10a connected to the receiving cavity; the control assembly 20 comprises a first terminal 21, a control board 23, a second terminal 22 and a cable. The control board 23 is located in the receiving cavity. The control board 23 is provided with a second terminal 22. The cable is located outside the housing 10 and connected to the first terminal 21. At least a portion of at least one of the first terminal 21 and the second terminal 22 is located at the wiring port 10a. The first terminal 21 and the second terminal 22 are detachably connected.
[0033] For example, at least a portion of the first terminal 21 is disposed in the wiring port 10a, and the second terminal 22 is located in the accommodating cavity. For another example, at least a portion of the second terminal 22 is disposed in the wiring port 10a, and the first terminal 21 is located outside the housing 10. For another example, at least a portion of the first terminal 21 and at least a portion of the second terminal 22 are both disposed in the wiring port 10a.
[0034] The control component 20 is used to control the operation of each component in the wall-mounted boiler 100. Exemplarily, the control component 20 can realize at least one of the functions of starting the wall-mounted boiler 100, stopping the wall-mounted boiler 100, and selecting the working mode of the wall-mounted boiler 100. For example, if the temperature of the water delivered by the wall-mounted boiler 100 is lower than the preset temperature, the control component 20 can start the heating function of the wall-mounted boiler 100, and the wall-mounted boiler 100 can quickly heat the water to the preset temperature to meet the demand for domestic water and improve the user experience. The control board 23 can be connected to an external device through the first terminal 21, the second terminal 22 and the cable.
[0035] The control panel 23 is hidden in the housing 10, and the housing 10 can prevent impurities, water and / or insects from contacting the control panel 23 and causing damage. The cable is located outside the housing 10, and the first terminal 21 and the second terminal 22 are connected at the wiring port 10a, that is, the first terminal 21 and the cable can be assembled first, and then the first terminal 21 and the second terminal 22 can be assembled, which is convenient for operation and convenient for operators to inspect and replace the cable.
[0036] In the wall-mounted boiler 100 provided in the embodiment of the present application, the cable is located outside the housing 10, and the first terminal 21 and the second terminal 22 are connected at the wiring port 10a. On the one hand, the first terminal 21 can be assembled with the cable first, and then assembled with the second terminal 22, which reduces the difficulty of assembly, improves production efficiency, and is convenient for operators to inspect and replace the cable. On the other hand, the housing 10 has a protective effect on the control panel 23, which can prevent impurities, water and / or small insects from contacting the control panel 23 and causing damage.
[0037] The wall-mounted boiler 100 provided in the embodiment of the present application can be installed on a vertical wall of an indoor space, and the indoor space includes but is not limited to a kitchen, a balcony, a bathroom, and the like.
[0038] For some examples, see Figure 1 and Figure 2 , the second terminal 22 partially extends out of the wiring port 10a, and the first terminal 21 is plugged into the second terminal 22. That is to say, the first terminal 21 can be located outside the housing 10, and the first terminal 21 and the second terminal 22 are plugged into each other outside the housing 10. In this way, the second terminal 22 has a good visual effect, and it is convenient for the first terminal 21 to be plugged into the second terminal 22. When the cable needs to be repaired, the first terminal 21 can be removed by pulling it out, without removing the housing 10 and the second terminal 22, and the operation is simple.
[0039] For example, see Figure 5 On the projection plane parallel to the wiring port 10a, the projection of the second terminal 22 and the projection of the wiring port 10a at least partially overlap, so that the gap between the second terminal 22 and the wiring port 10a can be reduced, and the sealing of the wall-mounted boiler 100 can be improved.
[0040] For some examples, see Figure 1 and Figure 2 The wiring port 10a is formed on the downward side wall of the housing 10. Taking the wall-mounted boiler 100 installed on the vertical wall of the kitchen as an example, the operator works under the wall-mounted boiler 100, the second terminal 22 extends downward, and the first terminal 21 and the cable part are both located under the housing 10, which is convenient for the operator to assemble the first terminal 21 and the second terminal 22, and at the same time, it is also convenient for the operator to lay and repair the cable.
[0041] It should be noted that, in the present application, down refers to the direction toward the ground, and up refers to the direction opposite to down.
[0042] In some embodiments, the cable includes at least one of a communication line, a temperature sensor line, and a manifold control line. In this way, different types of cables are connected to the control board 23 through the first terminal 21 and the second terminal 22, and different functions can be provided to the wall-mounted boiler 100.
[0043] Exemplarily, the communication line connects the control board 23 and the communicator to realize signal interaction between the wall-mounted boiler 100 and the communicator. For example, the type of the communication line includes but is not limited to a 485 communication line. The communicator can be a communication device using existing technology.
[0044] The temperature sensor line is connected to the temperature sensor disposed on the control board 23 to output a signal of the water temperature. The temperature sensor includes but is not limited to an NTC (Negative Temperature Coefficient, thermistor) temperature sensor.
[0045] The manifold control line can be used to start and stop the heating function of the wall-mounted boiler 100. For example, if the temperature of the water in the wall-mounted boiler 100 does not reach the preset temperature, the wall-mounted boiler 100 is in operation and heats the water; if the temperature of the water in the wall-mounted boiler 100 reaches the preset temperature, the wall-mounted boiler 100 is in standby mode.
[0046] For some examples, see Figure 3 and Figure 4 The wall-mounted boiler 100 includes a wire crimping cover 30, which is detachably connected to the outside of the housing 10 and covers the first terminal 21. In this way, the first terminal 21 is hidden in the wire crimping cover 30, and the wire crimping cover 30 has a protective effect on the first terminal 21, which can prevent water, impurities and / or small insects from contacting the first terminal 21 and causing damage.
[0047] For some examples, see Figure 1 and Figure 3The housing 10 includes a main housing 11 and a bottom housing 12. The main housing 11 is disposed on the bottom housing 12 to define a receiving cavity together. The wiring port 10a is formed on the bottom housing 12. The crimping cover 30 is detachably connected to the bottom housing 12. In this way, the crimping cover 30 can be assembled with the bottom housing 12 first, and then the bottom housing 12 is mounted on the main housing 11, thereby improving assembly efficiency.
[0048] The connection method between the wire crimping cover 30 and the bottom shell 12 includes but is not limited to screw connection or clamping connection, etc.
[0049] In some embodiments, the side wall of the wire crimping cover 30 abuts against the housing 10, and a wire routing groove 30a is formed on the side wall of the wire crimping cover 30, and the cable extends out of the wire crimping cover 30 through the wire routing groove 30a. Figure 4 Part of the peripheral side wall of the wire crimping cover 30 is folded to form a flange 31, and the flange 31 abuts against the housing 10, thereby increasing the connection area between the wire crimping cover 30 and the housing 10 and improving the connection stability between the wire crimping cover 30 and the housing 10. The wiring groove 30a can pass through the peripheral side wall of the wire crimping cover 30.
[0050] The wiring trough 30a has a guiding and limiting effect on the cables. Exemplarily, the wiring trough 30a extends along a first direction, so that under the guiding and limiting effect of the wiring trough 30a, the cables are prevented from being scattered, bent, entangled, etc. In this embodiment, the first direction is perpendicular to the up-down direction.
[0051] For some examples, see Figure 4 , at least one convex rib 32 is provided on each of the two groove walls opposite to each other in the radial direction of the cable in the wiring groove 30a. Exemplarily, the number of convex ribs 32 on a single groove wall can be one or more. That is to say, at least two convex ribs 32 clamp the two sides of the cable in the radial direction. In this way, on the one hand, the stability of the cable can be improved and the cable can be prevented from loosening and falling off. On the other hand, the convex rib 32 reduces the contact area between the cable and the two groove walls of the wiring groove 30a, which can reduce the problem of wear on the surface of the cable caused by the contact friction between the cable and the groove wall.
[0052] It should be noted that the "multiple" in the embodiments of the present application refers to a number including two or more.
[0053] In one embodiment, the height of the rib 32 protruding from the groove wall of the wiring groove 30a may be no greater than 1.5 mm (millimeter).
[0054] In some embodiments, at least two convex ribs 32 are staggered along the extension direction of the cable. Exemplarily, two convex ribs 32 are respectively provided on the two groove walls, and four convex ribs 32 are staggered along the extension direction of the cable. In this way, through the staggered arrangement of the convex ribs 32, the cable is roughly S-shaped in the wiring groove 30a, thereby increasing the friction between the convex ribs 32 and the cable, improving the tensile strength of the cable, and preventing the cable from loosening and falling off under the action of external force.
[0055] In some embodiments, the control assembly 20 includes a control box 24, which is disposed in the accommodating cavity. The control box 24 is formed with a relief opening 24a communicating with the wiring port 10a. The control board 23 is located in the control box 24, and the second terminal 22 extends out of the relief opening 24a. For example, see Figure 5 The control box includes a box cover 241 and a box body 242, the control board and the second terminal are located in the box body 242, and the box cover 241 covers the box body 242. In this way, the control box 24 can further protect the control board 23 and the second terminal 22, thereby improving the safety of the wall-mounted boiler 100.
[0056] The connection between the box cover 241 and the box body 242 can be a detachable connection, and the detachable connection includes but is not limited to a screw connection or a snap connection, etc.
[0057] For example, see Figure 5 On the projection plane parallel to the avoidance opening 24a, the projection of the second terminal 22 and the projection of the avoidance opening 24a at least partially overlap, so that the gap between the second terminal 22 and the avoidance opening 24a can be reduced, and the sealing of the control box 24 is improved.
[0058] In some embodiments, the control box 24 is detachably connected to the bottom shell 12, so that the control board 23 can be placed in the control box 24 first, and then the control box 24 is assembled with the bottom shell 12, and finally the bottom shell 12 is assembled to the main shell 11, thereby improving assembly efficiency. In addition, the control box 24, the control board 23 and the second terminal 22 can be inspected and replaced by installing and removing the bottom shell 12 without disassembling the main shell 11.
[0059] The control box 24 and the bottom shell 12 may be connected in a detachable manner, and the detachable connection includes but is not limited to a screw connection or a snap connection, etc.
[0060] For some examples, see Figure 5 The control assembly 20 includes a seal 25 located in the control box 24, and the seal 25 surrounds the second terminal 22. In other words, the seal 25 can seal the gap between the second terminal 22 and the inner wall surface of the control box 24. In this way, the seal 25 has a protective effect on the second terminal 22, can improve the stability of the second terminal 22, and can further improve the sealing performance of the control box 24.
[0061] The sealing member 25 may be a structure made of a flexible material. A flexible material refers to a material that can produce elastic deformation that can be bent, folded, twisted, compressed and / or stretched. For example, the sealing member 25 may be a sponge member.
[0062] In one embodiment, please refer to Figure 5 The sealing member 25 is formed with a notch 25a communicating with the avoidance opening 24a, and the second terminal 22 extends out of the notch 25a. On a projection plane parallel to the notch 25a, the projection of the second terminal 22 and the projection of the notch 25a at least partially overlap. In this way, the gap between the second terminal 22 and the notch 25a can be reduced, and the sealing performance of the control box 24 can be improved.
[0063] The second aspect of the embodiment of the present application provides a heating system, including the wall-mounted boiler 100 in any one of the embodiments of the present application. Exemplarily, the heating system includes at least one water inlet pipe and at least one water outlet pipe, and the wall-mounted boiler 100 is connected to the water outlet pipe and the water inlet pipe. For example, water enters the wall-mounted boiler 100 through the water inlet pipe for heating, and the heated water is discharged through the water outlet pipe. In this way, the heating system can provide hot water to users, meet the user's domestic hot water needs, and improve user experience.
