Description

Technical Field

[0001] This utility model relates to the field of heating equipment technology, specifically to a water inlet valve assembly and a wall-mounted boiler. Background Technology

[0002] A wall-hung boiler is a heating device that uses gas as its energy source. It primarily uses natural gas or coal gas as fuel and water as the medium to deliver heat. The circulating water inside the boiler is repeatedly heated during its circulation, continuously transferring heat to the building to provide a heat source and hot water for bathing. With the development of science and technology and the improvement of people's living standards, wall-hung boilers have become increasingly common in most households as heating devices, and most are installed in kitchens or outdoors.

[0003] Currently, in order to obtain relatively healthy hot water, wall-hung boilers usually have a sterilization function, which is generally achieved by installing ultraviolet germicidal lamps or ozone sterilization devices in the water flow pipes of the wall-hung boiler.

[0004] However, in related sterilization technologies, the structure of the sterilization device combined with the water flow pipeline of the wall-hung boiler becomes more complex, and the connection points are prone to leakage, resulting in poor sterilization effect and affecting safety. Utility Model Content

[0005] In view of the above-mentioned defects in the prior art, the present invention provides an inlet valve assembly and a wall-hung boiler to solve at least one of the above-mentioned technical defects in the prior art, making the structure of the sterilization device combined with the wall-hung boiler simpler, less prone to leakage, and with better sterilization effect and safety.

[0006] The second aspect of this utility model provides a wall-hung boiler.

[0007] To achieve the purpose of this utility model, the present utility model provides a water inlet valve assembly, comprising:

[0008] The water inlet valve base has an electrolysis chamber, and the water inlet valve base has a water inlet channel and a water outlet channel. The electrolysis chamber connects the water inlet channel and the water outlet channel.

[0009] An electrolytic electrode is disposed in the electrolytic chamber. The electrolytic electrode includes a first electrode and a second electrode, both of which are electrically connected to an external power source.

[0010] A cover, detachably mounted on the water inlet valve base, is suitable for sealing the electrolysis chamber, and the electrolysis electrode is fixed to the cover.

[0011] Preferably, the end of the cover facing the electrolysis chamber is provided with a first fixing boss and a second fixing boss.

[0012] The first electrode is disposed on the first fixed boss, and the second electrode is disposed on the second fixed boss.

[0013] A groove is provided between the first fixed boss and the second fixed boss, and the first electrode and the second electrode are both located above the groove.

[0014] Preferably, the first electrode includes a plurality of positive electrodes, and the second electrode includes a plurality of negative electrodes.

[0015] Each adjacent positive electrode is spaced apart, and each adjacent negative electrode is spaced apart.

[0016] Each of the positive electrodes and each of the negative electrodes are interleaved, and an electrolytic gap is provided between each adjacent positive electrode and negative electrode.

[0017] Preferably, the electrolytic gap between each adjacent positive electrode and negative electrode that are interleaved is the same.

[0018] Preferably, it further includes a first fixing member, a second fixing member, a first conductive member, and a second conductive member.

[0019] The first fixing boss has a first fixing through hole, and the second fixing boss has a second fixing through hole.

[0020] The first fixing member extends from one end of the cover body toward the electrolysis chamber into the first fixing through hole and is fixedly connected to the first conductive member, thereby fixing the first electrode to the first fixing boss.

[0021] The second fixing member extends from one end of the cover body toward the electrolysis chamber into the second fixing through hole and is fixedly connected to the second conductive member, thereby fixing the second electrode to the second fixing boss.

[0022] Preferably, it also includes a first seal and a second seal.

[0023] The first sealing element is disposed in the first fixing through hole and is sealedly connected to the first fixing element.

[0024] The second sealing element is disposed in the second fixing through hole and is sealed to the second fixing element.

[0025] Preferably, it also includes a first sealing ring and a second sealing ring.

[0026] Both the first sealing ring and the second sealing ring are disposed on the cover and abut against the inner wall of the electrolysis chamber.

[0027] Preferably, the value of the electrolytic gap is in the range of 2 to 5 mm.

[0028] Preferably, the electrolytic electrode is circular in shape.

[0029] The second aspect of this utility model provides a wall-hung boiler, including the aforementioned inlet valve assembly and the boiler body.

[0030] The water inlet valve assembly is located on the wall-hung boiler body.

[0031] The beneficial effects of this utility model are as follows: The water inlet valve assembly provided by this utility model has an electrolysis chamber that connects the water inlet channel and the water outlet channel. An electrolysis electrode with a first electrode and a second electrode that are electrically connected to an external power source is set in the electrolysis chamber. This allows bathroom water to enter the electrolysis chamber through the water inlet channel. After being electrolyzed and sterilized in the electrolysis chamber, it can flow out to the user through the water outlet channel. The cover is detachably installed on the water inlet valve base to seal the electrolysis chamber. This simplifies the connection structure between the electrolysis electrode and the water inlet valve base, and makes it less prone to leakage at the connection between the water inlet valve base and the cover. The electrolysis sterilization effect is better, safer, and easier to disassemble, maintain, or clean.

[0032] The wall-hung boiler provided by this utility model, due to including the aforementioned inlet valve assembly, inevitably possesses all the advantages of that assembly. That is, the boiler also allows bathroom water to enter the electrolysis chamber through the inlet channel, be electrolyzed and sterilized within the electrolysis chamber, and then flow out to the user through the outlet channel. The removable cover is mounted on the inlet valve base to seal the electrolysis chamber, simplifying the connection structure between the electrolysis electrode and the inlet valve base. Leakage is also less likely at the connection between the inlet valve base and the cover, resulting in better electrolysis sterilization, greater safety, and easier disassembly, maintenance, or cleaning.

Detailed Implementation

[0049] To facilitate understanding of this utility model, a more comprehensive description of this utility model will be given below with reference to the accompanying drawings.

[0050] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to and integrated with the other component, or there may be an intervening component present. The terms "mounted," "one end," "the other end," and similar expressions used in this document are for illustrative purposes only.

[0051] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this applies. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0052] The following is combined Figures 1 to 9 The embodiments of this utility model will be described below. It should be understood that the following description is merely an illustrative embodiment of this utility model and does not constitute any limitation on this utility model.

[0053] An embodiment of this utility model provides a water inlet valve assembly, which is mounted on the body 1 of a wall-mounted boiler. The water inlet valve assembly includes a water inlet valve base 100, an electrolytic electrode 200, and a cover 300.

[0054] The inlet valve base 100 has an electrolysis chamber 110, an inlet channel 120, and an outlet channel 130. The electrolysis chamber 110 connects the inlet channel 120 and the outlet channel 130. Bath water can enter the inlet valve base 100 through the inlet channel 120, pass through the electrolysis chamber 110, and then flow out through the outlet channel 130.

[0055] An electrolysis electrode 200 is disposed in the electrolysis chamber 110. The electrolysis electrode 200 includes a first electrode 210 and a second electrode 220, both of which are electrically connected to an external power source. When energized, the first electrode 210 and the second electrode 220 electrolyze the bathroom water flowing through the electrolysis chamber 110. After electrolysis, the bathroom water generates hydroxyl radicals (-OH), which have bactericidal and pesticide residue-removing effects, making the bathroom water healthier and more comfortable. The electrolysis electrode 200 can be made of titanium alloy, and the external power source can be a low-voltage power source.

[0056] The electrolysis electrode 200 is fixed to the cover 300, which is detachably mounted on the inlet valve base 100. The cover 300 can be fixedly connected to the inlet valve base 100 via a threaded fastener 480, which can seal the electrolysis chamber 110, prevent leakage, and ensure electrolysis effect and safety. The cover 300 can be made of high-strength nylon.

[0057] It is understood that the water inlet valve assembly provided in the embodiments of this utility model, by setting an electrolysis chamber 110 connecting the water inlet channel 120 and the water outlet channel 130, and setting an electrolysis electrode 200 with a first electrode 210 and a second electrode 220 electrically connected to an external power source in the electrolysis chamber 110, allows bathroom water to enter the electrolysis chamber 110 through the water inlet channel 120, be electrolyzed and sterilized in the electrolysis chamber 110, and then flow out to the user through the water outlet channel 130. The cover 300 is detachably installed on the water inlet valve base 100 to seal the electrolysis chamber 110, making the connection structure between the electrolysis electrode 200 and the water inlet valve base 100 simpler, and the connection between the water inlet valve base 100 and the cover 300 less prone to leakage, resulting in better electrolysis sterilization effect, greater safety, and easier disassembly, maintenance, or cleaning.

[0058] Combination Figures 4 to 7 Furthermore, in some embodiments of this utility model, a first fixed boss 310 and a second fixed boss 320 are provided at one end of the cover 300 facing the electrolysis chamber 110.

[0059] The first electrode 210 is disposed on the first fixed boss 310, and the second electrode 220 is disposed on the second fixed boss 320.

[0060] A groove 330 is provided between the first fixed protrusion 310 and the second fixed protrusion 320, and the first electrode 210 and the second electrode 220 are both located above the groove 330; this leaves a gap between the first electrode 210 and the second electrode 220 and the cover 300, that is, the electrolytic electrode 200 can be suspended in the electrolysis chamber 110. Both sides of the first electrode 210 and the second electrode 220 can contact water, which expands the contact area between the electrolytic electrode 200 and the water, further increases the electrolysis effect and improves the electrolysis rate and efficiency.

[0061] Specifically, in combination Figure 8 In some embodiments of this utility model, the first electrode 210 includes a plurality of positive electrodes 211, and the second electrode 220 includes a plurality of negative electrodes 221.

[0062] Each adjacent positive electrode 211 is arranged at intervals, and each adjacent negative electrode 221 is also arranged at intervals.

[0063] Each positive electrode 211 and each negative electrode 221 are interleaved, and an electrolytic gap 230 is provided between each adjacent positive electrode 211 and negative electrode 221. This allows the first electrode 210 and the second electrode 220 to form a mutually mating tooth-like shape, that is, a negative electrode 221 is inserted into the gap between each adjacent positive electrode 211, and a positive electrode 211 is inserted into the gap between each adjacent negative electrode 221. This provides more electrolytic contact points between the water in the electrolysis chamber 110 and the electrolysis electrode 200, further improving the electrolysis efficiency and effect, thereby enhancing the sterilization ability.

[0064] Of course, in some embodiments of this utility model, the electrolytic gap 230 between each adjacent positive electrode 211 and negative electrode 221 that are interleaved is the same, which makes the structure of the electrolytic electrode 200 simpler and saves manufacturing costs.

[0065] In addition, combined Figure 5 and Figure 7 In some embodiments of this utility model, the water inlet valve assembly further includes a first fixing member 400, a second fixing member 410, a first conductive member 420, and a second conductive member 430.

[0066] The first fixing boss 310 is provided with a first fixing through hole 311, and the second fixing boss 320 is provided with a second fixing through hole 321.

[0067] The first fixing member 400 extends from the end of the cover 300 toward the electrolysis chamber 110 into the first fixing through hole 311 and is fixedly connected to the first conductive member 420, thereby fixing the first electrode 210 onto the first fixing boss 310.

[0068] The second fixing member 410 extends from the end of the cover 300 toward the electrolysis chamber 110 into the second fixing through hole 321 and is fixedly connected to the second conductive member 430, thereby fixing the second electrode 220 onto the second fixing boss 320. Both the first conductive member 420 and the second conductive member 430 can be electrically connected to an external power source through conductive wires 490.

[0069] Specifically, the first fixing member 400 and the second fixing member 410 can both be the same stainless steel fixing screw, and the first fixing through hole 311 and the second fixing through hole 321 can both be the same stepped through hole. The first conductive member 420 and the second conductive member 430 can both be the same conductive screw. The conductive screw is provided with a threaded hole. When the stainless steel fixing screw extends from the end of the cover 300 toward the electrolysis chamber 110 into the stepped through hole, the stainless steel fixing screw is screwed into the threaded hole on the conductive screw, making the fixing of the electrolysis electrode 200 simpler. It cleverly combines the fixing of the first electrode 210 and the second electrode 220 with the connection of the external power supply, simplifying the structure of the fixed electrode connection and saving costs.

[0070] Combination Figure 5 and Figure 7 In some embodiments of this utility model, in order to prevent leakage at the fixed connection between the first electrode 210 and the second electrode 220 and the cover 300, and to improve the safety and efficiency of electrolytic sterilization, the water inlet valve assembly further includes a first sealing element 440 and a second sealing element 450.

[0071] The first sealing element 440 is disposed in the first fixing through hole 311 and is sealed to the first fixing element 400.

[0072] The second seal 450 is disposed in the second fixing through hole 321 and is sealed to the second fixing member 410. The first seal 440 and the second seal 450 can be rubber seals.

[0073] Furthermore, combined Figure 7 In some embodiments of this utility model, the water inlet valve assembly further includes a first sealing ring 460 and a second sealing ring 470.

[0074] Both the first sealing ring 460 and the second sealing ring 470 are provided on the cover 300, and the first sealing ring 460 and the second sealing ring 470 are sealed and abut against the inner wall of the electrolysis chamber 110. Two fixed step holes can be provided at the connection between the cover 300 and the electrolysis chamber 110. The fixed step holes can accommodate the first sealing ring 460 and the second sealing ring 470 to form a double sealing structure, which can effectively prevent leakage of the electrolysis chamber 110 and improve the electrolysis sterilization effect and safety.

[0075] Of course, in some embodiments of this utility model, in order to improve the electrolysis effect and efficiency of the electrolysis electrode 200, the value of the electrolysis gap 230 is in the range of 2 to 5 mm. For example, the electrolysis gap 230 can be 3 mm or 4 mm.

[0076] Moreover, the electrolysis electrode 200 can be circular, which makes the flow rate distribution of bath water through the electrolysis chamber 110 more uniform, avoiding local pressure that is too high or too low due to uneven flow rate, thereby extending the service life of the electrolysis electrode 200.

[0077] Combination Figures 1 to 9 In an embodiment of this utility model, a wall-hung boiler is also provided, which includes the above-mentioned water inlet valve assembly and the boiler body 1.

[0078] The water inlet valve assembly is located in the boiler body 1.

[0079] It is understood that the wall-hung boiler provided in the embodiments of this utility model, since it includes the above-mentioned water inlet valve assembly, necessarily possesses all the advantages of that assembly. That is, the wall-hung boiler can also allow bathroom water to enter the electrolysis chamber 110 through the water inlet channel 120, and after being electrolyzed and sterilized in the electrolysis chamber 110, it can flow out to the user through the water outlet channel 130. The cover 300 is detachably installed on the water inlet valve base 100 to seal the electrolysis chamber 110, making the connection structure between the electrolysis electrode 200 and the water inlet valve base 100 simpler, and the connection between the water inlet valve base 100 and the cover 300 less prone to leakage. The electrolysis sterilization effect is better, safer, and easier to disassemble, maintain, or clean.
