If there is a description of first, second, it is only for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated or the sequence of technical features indicated.

[0055] In the description of the present application, unless otherwise explicitly limited, the words such as setting, mounting, connecting, and the like should be broadly understood, and the person skilled in the art can reasonably determine the specific meaning of the above words in the present application in combination with the specific content of the technical solution.

[0056] There are various types of water heaters, for example, air energy water heater, electric water heater or water heater combining air energy heating and electric heating. The water heater generally comprises an inner container and an outer shell. The interface position of the inner container is provided with electric heating element, temperature controller and temperature sensor and other components. The electric heating element is used for heating water in the inner container. The temperature sensor can be temperature sensing bag or other suitable temperature sensor. The temperature sensor can detect the temperature of water in the inner container and transmit the detected result information to the temperature controller. The temperature controller can control the on-off of the circuit according to the result information transmitted by the temperature sensor, thereby playing a protection role. The circuit connected with the electric heating element and the temperature controller is generally a strong electric circuit, and the circuit connected with the temperature sensor is generally a weak electric circuit. The inner container and the outer shell are filled with foaming material such as polyurethane foaming agent. The foaming material plays a sealing and heat insulation role.

[0057] In the related art, in order to prevent the foaming material between the inner container and the outer shell from contacting the components and causing contamination or damage of the components, a foaming blocking component such as foam or pearl wool is arranged at the interface position of the inner container. The foaming blocking component plays a sealing role to avoid the foaming material from contacting the components. However, the foaming blocking component such as foam or pearl wool is not convenient for separating the strong electric circuit connected with the electric heating element and the temperature controller and the weak electric circuit connected with the temperature sensor, thereby easily causing strong and weak electric interference, thereby affecting the normal operation of the equipment.

The bracket 100 is provided with a second wiring structure 130, which is separated from the first wiring structure 120, and the second wiring structure 130 is used for wiring the weak current line 521, and the second wiring structure 130 can be provided with one and located in the middle of the left side of the bracket 100, and the weak current line 521 connected to the temperature sensor 514 is wired from the second wiring structure 130, of course, when the inner container 500 also has other components 510 connected to the weak current line 521, the second wiring structure 130 can also be provided with two or more, which will not be described here.

[0063] Reference Figure 3 、 Figure 5 、 Figure 8 、 Figure 10 、 Figure 13 and Figure 15As shown, the first cover 200 is connected with the bracket 100, for example, the first cover 200 can be clamped with the bracket 100, of course, the first cover 200 and the bracket 100 can also be welded, bonded, connected through fasteners or integrally formed, etc. The first cover 200 covers the accommodation opening 110, and when the component 510 passes through the accommodation opening 110, the first cover 200 can just cover the component 510, and through the cooperation of the first cover 200 and the bracket 100, the foaming material between the inner container 500 and the outer shell 600 can be prevented from contacting the component 510, so as to prevent the component 510 from being contaminated or damaged.

[0064] It should be noted that the bracket 100 and the first cover 200 can be made of fireproof material, for example, can be injection molded by fireproof plastic, compared with the existing foam, pearl cotton and other bubble blocking pieces, the fireproof effect is better, and the safety is higher.

[0065] According to the bubble blocking structure of the present application, the strong current line 520 connected with the electric heating element 512 and the temperature controller 513 can be wired from the first wiring structure 120, and the weak current line 521 connected with the temperature sensor 514 can be wired from the second wiring structure 130, and the second wiring structure 130 and the first wiring structure 120 are separated from each other, thereby realizing the separation of the strong current line 520 and the weak current line 521, so as to avoid the interference of strong and weak electricity and affect the normal operation of the equipment.

[0066] Reference Figure 7 and Figure 14 As shown, in some embodiments of the present application, the bracket 100 includes a bottom plate 140 and a side plate 150, the accommodation opening 110 is arranged on the bottom plate 140, and the side plate 150 is arranged on the circumferential side of the bottom plate 140, wherein the bottom plate 140 and the side plate 150 define a containing groove 160 for containing the component 510. For example, the bottom plate 140 can be bonded to the outer side wall of the inner container 500 through a bonding structure, the bottom plate 140 can also be adapted to the outer side wall of the inner container 500 and directly bonded or welded to the outer side wall of the inner container 500, in addition, the bottom plate 140 can also be installed on the outer side wall of the inner container 500 through fasteners. The side plate 150 is located on the circumferential side of the bottom plate 140 and surrounds the accommodation opening 110, and after the component 510 passes through the accommodation opening 110, it is just contained in the containing groove 160 defined by the bottom plate 140 and the side plate 150. The side plate 150 surrounds the circumferential side of the component 510, thereby effectively preventing the foaming material on the circumferential side of the component 510 from contacting the component 510 and causing the component 510 to be contaminated or even damaged, and in addition, the covering effect of the first cover 200 makes the protection effect of the component 510 better.

[0067] It should be noted that the first cover 200 can be located in the accommodating groove 160 entirely or partially, for example, one end of the first cover 200 close to the bottom plate 140 can be located in the accommodating groove 160, so that the sealing effect is better. Of course, the first cover 200 can also be provided with a side wall, and the side wall of the first cover 200 surrounds the outer side wall of the support 100 and is attached to the outer side wall of the support 100, so that the sealing effect is also improved.

[0068] Referring to Figure 4 , Figure 7 , Figures 12 to 14 It should be noted that the first cover 200 can be located in the accommodating groove 160 entirely or partially, for example, one end of the first cover 200 close to the bottom plate 140 can be located in the accommodating groove 160, so that the sealing effect is better. Of course, the first cover 200 can also be provided with a side wall, and the side wall of the first cover 200 surrounds the outer side wall of the support 100 and is attached to the outer side wall of the support 100, so that the sealing effect is also improved.

[0069] It should be noted that in some other embodiments of the present application, the first wiring structure 120 and the second wiring structure 130 can also be provided as wiring holes, which are also simple in structure, convenient to set, and convenient for wiring. Of course, the first wiring structure 120 and the second wiring structure 130 can also be other suitable structures, for example, they can be line cards.

[0070] Referring to Figure 4 , Figure 7 , Figure 12 and Figure 14 It should be noted that in some other embodiments of the present application, the first wiring structure 120 and the second wiring structure 130 can also be provided as wiring holes, which are also simple in structure, convenient to set, and convenient for wiring. Of course, the first wiring structure 120 and the second wiring structure 130 can also be other suitable structures, for example, they can be line cards.

[0071] It should be noted that in some other embodiments of the present application, the first wiring structure 120 can also be located below the accommodating groove 160. When the first wiring structure 120 is located below the accommodating groove 160, the condensed water condensed on the surface of the strong current line 520 will not flow back into the bracket 100, regardless of whether the first wiring structure 120 extends vertically or obliquely.

[0072] Referring to Figure 4 , Figure 7 , Figure 12 and Figure 14 , in further embodiments of the present application, the second wiring structure 130 is located on one side of the accommodating groove 160, and the second wiring structure 130 extends obliquely downward away from the accommodating groove 160. For example, the second wiring structure 130 can be provided as a wiring groove or a wiring hole, and the second wiring structure can be one. The second wiring structure can be located on the left side of the accommodating groove 160 and extend obliquely downward in the left direction. In this way, when the weak current line 521 connected to the temperature sensor 514 is wired from the second wiring structure 130, the end of the weak current line 521 close to the bracket 100 will extend obliquely downward away from the accommodating groove 160, thereby avoiding the condensed water condensed on the surface of the weak current line 521 from flowing back into the bracket 100 and damaging the components 510, and the practicability is better.

[0073] It should be noted that in some other embodiments of the present application, the second wiring structure 130 can also be located below the accommodating groove 160. When the second wiring structure 130 is located below the accommodating groove 160, the condensed water condensed on the surface of the weak current line 521 will not flow back into the bracket 100, regardless of whether the second wiring structure 130 extends vertically or obliquely.

[0074] Referring to Figures 1 to 6 , Figure 9 , Figure 10 and Figure 13 , in further embodiments of the present application, the end surface of the side plate 150 away from the bottom plate 140 is attached with a first sealing member 300, and the first sealing member 300 surrounds the accommodating groove 160. For example, the first sealing member 300 can be made of elastic materials such as sponge and rubber, and the first sealing member 300 can be bonded, welded or connected by fasteners with the end surface of the side plate 150 away from the bottom plate 140. When the bubble plug assembly is installed between the inner container 500 and the outer shell 600, the end surface of the first sealing member 300 away from the side plate 150 can be attached to the inner surface of the outer shell 600.

[0075] In the embodiment, the first sealing member 300 is arranged, so that the foaming material is prevented from entering the accommodating cavity from the gap between the support 100 and the shell 600 to contact the component 510, and the sealing effect is better. In addition, the first sealing member 300 is elastically deformed when being pressed by the shell 600, and is partially pressed into the wiring groove to tightly contact the strong electric line 520 or the weak electric line 521, so that the foaming material is prevented from entering the accommodating cavity from the wiring groove to contact the component 510, and the sealing effect is better. In addition, the first sealing member 300 also has a buffering effect, and prevents the rigid impact force between the support 100 and the shell 600 from being too large to damage the support 100 and the shell 600.

[0076] Reference Figure 2 and Figure 13 As shown in FIGS. 13 and 14, in some other embodiments of the present application, the end face of the bottom plate 140 away from the accommodating groove 160 is attached with a second sealing member 400, and the second sealing member 400 surrounds the accommodation opening 110. For example, the second sealing member 400 can be made of sponge, rubber or other elastic materials, and the second sealing member 400 can be attached with the end face of the bottom plate 140 away from the accommodating groove 160. Specifically, the two end faces of the second sealing member 400 can be coated with glue, the end face of the second sealing member 400 close to the bottom plate 140 is attached with the bottom plate 140, and the end face of the second sealing member 400 away from the bottom plate 140 is attached with the outer side wall of the inner container 500. Of course, the bottom plate 140 can be connected with the inner container 500 through fasteners, and the second sealing member 400 is clamped between the bottom plate 140 and the inner container 500.

[0077] In the embodiment, the second sealing member 400 is arranged, so that the foaming material is prevented from entering from the gap between the support 100 and the inner container 500 to contact the component 510, and the sealing effect is better. In addition, the second sealing member 400 also has a buffering effect, and prevents the rigid impact force between the support 100 and the inner container 500 from being too large to damage the support 100 and the inner container 500.

[0078] Reference Figure 4 , Figure 7 , Figure 12 and Figure 14As shown, in some embodiments of the present invention, the first wiring structure 120 and the second wiring structure 130 are located on opposite sides of the bracket 100. For example, the first wiring structure 120 can be located on the right side of the bracket 100, and the second wiring structure 130 can be located on the left side of the bracket 100. Consequently, the high-voltage line 520 connected to the electric heating element 512 and the temperature controller 513 can leave from the first wiring structure 120 on the right side of the bracket 100, and the low-voltage line 521 connected to the temperature sensor 514 can leave from the second wiring structure 130 on the left side of the bracket 100. This results in better separation of high and low voltage circuits, thereby further preventing interference between high and low voltage circuits from affecting the normal operation of the equipment.

[0079] It should be noted that the first wiring structure 120 and the second wiring structure 130 can also be located in other positions on the bracket 100, such as at the top and bottom of the bracket 100, respectively, which will not be elaborated here. When the first wiring structure 120 and the second wiring structure 130 are located on the left and right sides of the bracket 100, the heights of the first wiring structure 120 and the second wiring structure 130 can be different to achieve better separation of strong and weak current.

[0080] refer to Figure 3 , Figure 5 as well as Figure 8 As shown, in some embodiments of the present invention, the end face of the first cover 200 facing away from the clearance opening 110 is provided with a third wiring structure 210, which is used for wiring. Electronic ball valves and level switches are installed in other suitable locations on the water heater 1000. The wiring connected to the electronic ball valves and level switches is a low-voltage line 521.

The outer shell 600 is sleeved on the outside of the inner container 500, and the bubble blocking assembly is arranged between the inner container 500 and the outer shell 600.

[0093] According to the water heater 1000 of the present application, by using the above-mentioned bubble blocking assembly, the bracket 100 is installed on the outer side wall of the inner container 500, and the components 510 connected to the strong electric circuit 520 such as the electric heating element 512 and the temperature controller 513, and the components 510 connected to the weak electric circuit 521 such as the temperature sensor 514, pass through the accommodation opening 110 of the bracket 100, and the first cover 200 covers the accommodation opening 110, that is, covers the components 510, thereby being able to cooperate with the bracket 100 to prevent the foaming material between the inner container 500 and the outer shell 600 from contacting the components 510 and causing damage to the components 510. The strong electric circuit 520 connected to the electric heating element 512 and the temperature controller 513 can be routed from the first routing structure 120, and the weak electric circuit 521 connected to the temperature sensor 514 can be routed from the second routing structure 130, thereby being able to realize the separation of the strong electric circuit 520 and the weak electric circuit 521, so as to avoid the interference of strong and weak electricity and affect the normal operation of the equipment.

[0094] It can be understood that, since the water heater 1000 adopts all the technical solutions of the bubble blocking assembly of the first aspect embodiment, it has all the beneficial effects brought by the technical solutions of the first aspect embodiment, which will not be repeated here.

[0095] It should be noted that the water heater 1000 can be an air energy water heater, an electric water heater, or a water heating device that combines air energy heating and electric heating. Of course, the water heater 1000 can also be other water heating devices that need to be provided with a bubble blocking assembly, which will not be repeated here.

[0096] Reference Figure 16 As shown in the drawings, in some embodiments of the present application, the shell 600 is provided with an access opening 610 and a socket 620 corresponding to the bubble blocking assembly, the inner container 500 is provided with a first grounding wire 522, the other end of the first grounding wire 522 is provided with a plug-in part, the plug-in part is inserted into the socket 620, and the shell 600 is provided with a detachable second cover 630 covering the access opening 610 and the socket 620.

[0097] For example, the inner container 500 can be provided with a grounding terminal 516, one end of the first grounding wire 522 is connected to the grounding terminal 516, and the other end is provided with a plug-in part. The shell 600 can be provided with a plurality of through holes on the circumferential side of the access opening 610, one of which is configured as the socket 620, and the rest are configured as first mounting holes. The second cover 630 can be provided with a plurality of second mounting holes corresponding to the first mounting holes.

[0098] The first grounding wire 522 connects the inner container 500 and the shell 600. When the components 510 on the inner container 500 leak electricity or generate static electricity, it can be directly transmitted to the shell 600 through the first grounding wire 522, and the shell 600 can be transmitted to the ground through other grounding wires, thereby avoiding the risk of short circuit or electric shock, and the safety is better.

After installing the second cover 630, the second cover 630 covers the access opening 610 and the socket 620, which is not only more beautiful, but also has a protective effect, which can avoid damage caused by exposure of the bubble blocking assembly. In addition, it can also avoid the risk of electric shock caused by the casual contact of the bubble blocking structure and the plug-in part of the first grounding wire 522 by the staff, and the safety is better.

[0099] It should be noted that the ground terminal 516 can also be connected with a second ground wire 523, which can be connected with the electric appliance box of the water heater 1000. In addition, the water heater 1000 generally also includes a base, and a third ground wire can also be connected between the shell 600 and the base. Thus, when the device in the electric appliance box leaks or generates static electricity, the static electricity can be transmitted to the inner container 500 through the second ground wire 523, then transmitted to the shell 600 through the first ground wire 522, and finally transmitted to the base through the third ground wire. Since the base can contact the ground, the static electricity can finally be transmitted to the ground, thereby reducing the risk of short circuit and electric shock and improving safety. The first ground wire 522 and the second ground wire 523 can be routed from the first routing structure 120 or other suitable positions, and thus will not be described here in detail.

[0100] It can be understood that other configurations and operations of the water heater 1000 according to the embodiments of the present application are known to those of ordinary skill in the art, and thus will not be described in detail here.
