[0002] The wall-hanging stove is a common household heating equipment, which can not only provide domestic hot water for users, but also provide heating for the family. When providing domestic hot water, the water inlet valve of the wall-hanging stove continuously provides cold water into the heat exchanger, and the cold water exchanges heat with the hot water from the wall-hanging stove in the heat exchanger to form warm water, which flows out from the water outlet valve for users to use.

[0044] The wall-hanging stove is a common household heating equipment, which can not only provide domestic hot water for users, but also provide heating for the family. When providing domestic hot water, the water inlet valve of the wall-hanging stove continuously provides cold water into the heat exchanger, and the cold water exchanges heat with the hot water from the wall-hanging stove in the heat exchanger to form warm water, which flows out from the water outlet valve for users to use.

[0045] The water inlet valve used in the market at present is constant flow, and the flow size cannot be adjusted in the use process, but with the change of cold and hot weather, the water temperature also changes, when the water temperature is higher, the same gas is enough to heat the water to a very high temperature. For example, the maximum heat value of the 20KW wall-hanging stove can only heat 8L / min water flow from 5℃ to 40℃, when the outside temperature is high in summer, the cold water temperature will reach 25℃, so if the water flow is still limited to 8L / min, the water temperature will rise quickly, and even the temperature exceeds 40℃, which will scald people and affect the user's experience, at this time, it is necessary to increase the water flow from 8L / min to 10L / min or higher.

[0046] To solve the above problems, the embodiment provides a water inlet valve which can adjust the water inlet flow of bathroom water, adapt to different user needs, and bring comfortable experience to users. The water inlet valve is applied to a water supply module of a wall-hanging stove. The water supply module specifically comprises the water inlet valve, a water outlet valve, and a plate heat exchanger connected between the water inlet valve and the water outlet valve. The water inlet valve is connected with a cold water source. The water outlet valve is connected with the wall-hanging stove. The plate heat exchanger has a hot water channel and a cold water channel. In the heating state, the wall-hanging stove provides hot water to the heating pipeline through the water outlet valve, and then the hot water is delivered back to the wall-hanging stove through a water pump, forming a medium circulation. In the bathroom state, the hot water in the wall-hanging stove flows to the hot water channel of the plate heat exchanger through the water outlet valve. The external cold water flows to the cold water channel of the plate heat exchanger through the water inlet valve. Thus, the cold water in the cold water channel and the hot water in the hot water channel complete heat exchange to form warm water, and the warm water flows to the bathroom pipeline from the bathroom water outlet of the water outlet valve to supply water for the bathroom, for the user to use. This part is prior art, and will not be described in detail.

[0047] Specifically, as shown in Figure 1 and Figure 3 , the water inlet valve comprises a valve body 1 and an electromagnetic valve assembly 2. The inside of the valve body 1 is provided with a first water inlet channel 1111, a second water inlet channel 1121, and a water outlet channel 1122. The valve body 1 is provided with a water inlet interface 121, a bathroom heat exchange interface 122, a heating heat exchange interface 123, and a water pump interface 127. The direction in which the water inlet interface 121 points is the front direction. The electromagnetic valve assembly 2 is located above. The bathroom heat exchange interface 122 and the heating heat exchange interface 123 are both located at the lowermost side of the valve body 1. The heating heat exchange interface 123 is close to the water inlet interface 121. The bathroom heat exchange interface 122 is away from the water inlet interface 121. The water pump interface 127 is located at the right side of the valve body 1 close to the water inlet interface 121. The water inlet interface 121 is used to communicate with an external cold water source. The bathroom heat exchange interface 122 is used to communicate with the inlet of the cold water channel of the plate heat exchanger. The heating heat exchange interface 123 is used to communicate with the outlet of the hot water channel of the plate heat exchanger. The outlet of the cold water channel and the inlet of the hot water channel of the plate heat exchanger are both connected with the water outlet valve. The water pump interface 127 is connected with the heating heat exchange interface 123 and is used to connect a water pump. The water pump is used to deliver the medium back to the wall-hanging stove. The water inlet interface 121 is connected with the first water inlet channel 1111 and the second water inlet channel 1121 respectively. The water outlet channel 1122 is connected with the second water inlet channel 1121 and the bathroom heat exchange interface 122 respectively. The electromagnetic valve assembly 2 comprises a valve seat 23 and an electromagnetic valve installed on the valve seat 23. The valve seat 23 is arranged on the valve body 1. The valve seat 23 is provided with a first channel 231 which connects the first water inlet channel 1111 and the water outlet channel 1122. The output end of the electromagnetic valve can open or close the first channel 231.

[0048] In the bathroom state, the water inlet valve plays a role of domestic water inlet, the second water inlet channel 1121 acts as a normally open channel, and the second water inlet channel 1121 and the water outlet channel 1122 are in a normally connected state. The opening or closing of the first channel 231 is controlled by the electromagnetic valve, so as to achieve the purpose of increasing the flow at any time.

[0049] In combination Figure 3 When water is inlet, the external cold water flows into the second water inlet channel 1121 from the water inlet interface 121. In the case of low water temperature, the electromagnetic valve closes the first channel 231, the cold water flows from the second water inlet channel 1121 to the water outlet channel 1122, and then flows to the cold water channel of the plate heat exchanger through the bathroom heat exchange interface 122, exchanges heat with the hot water in the hot water channel to form warm water, and then flows to the water outlet valve from the outlet of the cold water channel, and finally flows to the bathroom pipeline from the bathroom water outlet of the water outlet valve to supply water for the bathroom for the user to use. The hot water in the hot water channel after heat exchange flows to the water pump interface 127 through the heating heat exchange interface 123, and the water pump retransmits the hot water back to the wall-mounted stove for heating. In summer, the same gas is enough to heat the water to a very high temperature. At this time, the first channel 231 is opened by the electromagnetic valve to increase the flow. After the cold water flows out of the second water inlet channel 1121, it is divided into two paths. One path of the cold water directly enters the water outlet channel 1122, and the other path of the cold water enters the water outlet channel 1122 through the first channel 231. The two paths of the cold water converge in the water outlet channel 1122, and finally flow to the cold water channel of the plate heat exchanger through the bathroom heat exchange interface 122 for heat exchange to form warm water, so as to avoid that the water temperature after heating is too high to scald the user. As can be seen, the water inlet valve provided in the embodiment can adjust the size of the flow according to the cold and heat of the weather, so as to meet different temperature requirements and improve the user experience.

[0050] Specifically, as shown in Figure 3 The electromagnetic valve includes an electromagnetic coil 21 and a plugging piece 22. The electromagnetic coil 21 is fixedly installed on a valve seat 23. The plugging piece 22 includes a sealing seat 221 and a sealing gasket 222. The sealing seat 221 is connected to an output end of the electromagnetic coil 21. The sealing gasket 222 is fixedly installed on the lower side of the sealing seat 221. The sealing gasket 222 can be made of rubber material, which is soft. The sealing seat 221 supports the sealing gasket 222, so that a good sealing effect is achieved. The specific structure and working principle of the electromagnetic coil 21 belong to the prior art, and will not be described here.

[0051] Further, as shown in Figure 3 and Figure 4As shown, the valve seat 23 is further provided with a second channel 232 independent of the first channel 231, the second channel 232 is arranged adjacent to the first channel 231 and is independent of each other, and the second water inlet channel 1121 and the water outlet channel 1122 are directly communicated through the second channel 232. One side of the valve seat 23 is further provided with a water outlet 233, and the water outlet 233 communicates the second channel 232 and the water outlet channel 1122.

[0052] When the water temperature is low, the electromagnetic coil 21 drives the obturator 22 to move downward to close the first channel 231, the first channel 231 is cut off with the water outlet 233, the second channel 232 is communicated with the water outlet 233, cold water flows from the second water inlet channel 1121 into the second channel 232, and then flows from the water outlet 233 into the water outlet channel 1122, and finally flows through the bathroom heat exchange interface 122 into the plate heat exchanger for heat exchange to form warm water. In summer, when the water temperature is relatively high, the same gas can heat the water to a very high temperature, at this time the electromagnetic coil 21 drives the obturator 22 to rise to open the first channel 231 to increase the flow, at this time the first channel 231 and the second channel 232 are communicated with the water outlet 233, one way of cold water flows from the second water inlet channel 1121 into the second channel 232, and then flows out from the water outlet 233 into the water outlet channel 1122, another way of cold water flows from the second water inlet channel 1121 into the first channel 231, and then flows out from the water outlet 233 into the water outlet channel 1122, the two ways of cold water are combined in the water outlet channel 1122, and finally flow through the bathroom heat exchange interface 122 to the plate heat exchanger for heat exchange to form warm water, so as to avoid that the water after heating is too high to scald the user, so as to meet different temperature requirements and improve the user experience.

[0053] Further, as shown in Figure 3 and Figure 5 , the bottom of the second channel 232 is provided with a flow limiting ring 24. The flow limiting ring 24 is used to limit the amount of cold water entering the second channel 232, so as to ensure that the cold water can be heated to a suitable temperature under limited heat power. It should be noted that the flow limiting ring 24 is provided with a flow limiting hole to generate flow-stable water. The specific structure and working principle of the flow limiting ring 24 both belong to the prior art, and will not be described here.

[0054] In an optional embodiment, the inside of the valve body 1 is further provided with a first water inlet channel 1111 independent of the second water inlet channel 1121, and the first water inlet channel 1111 communicates the water inlet interface 121 and the first channel 231. The first water inlet channel 1111 is arranged in parallel with and spaced from the second water inlet channel 1121, and the first water inlet channel 1111 also serves as a normally open channel and is selectively communicated between the water outlet channel 1122 and the first channel 231.

[0055] In combination with Figure 3When water is input, the external cold water flows into the water inlet interface 121 and is divided into two paths, one of which flows into the first water inlet channel 1111, and the other of which flows into the second water inlet channel 1121. When the water temperature is low, the electromagnetic valve closes the first channel 231, and the cold water flows from the second water inlet channel 1121 into the water outlet channel 1122, and then flows to the plate heat exchanger through the bathroom heat exchange interface 122 to exchange heat to form warm water for use by the user. In summer, when the water temperature is relatively high, the same amount of gas is sufficient to heat the water to a very high temperature, at which time the first channel 231 is opened by the electromagnetic valve to increase the flow, and part of the cold water in the second water inlet channel 1121 directly enters the water outlet channel 1122 through the second channel 132, and the other part of the cold water enters the water outlet channel 1122 through the first channel 231. At the same time, the cold water in the first water inlet channel 1111 also enters the water outlet channel 1122 through the first channel 231, and the cold water from the several paths eventually converges in the water outlet channel 1122, and finally flows to the cold water channel of the plate heat exchanger through the bathroom heat exchange interface 122 to exchange heat to form warm water, thereby achieving an increase in the water outlet flow and avoiding the water temperature after heating being too high to scald the user.

[0056] Further, as shown in Figure 3 The top of the valve body 1 is provided with a valve cavity 115, and part of the valve seat 23 is accommodated in the valve cavity 115. The part of the valve seat 23 outside the valve cavity 115 is fixed on the valve body 1 by a screw. The cavity bottom of the valve cavity 115 is also provided with a communication cavity 116, which communicates with the first channel 231 and the second channel 232. The communication cavity 116 is located at the top of the first water inlet channel 1111 and the second water inlet channel 1121, and the first water inlet channel 1111 and the second water inlet channel 1121 are connected by the communication cavity 116. When water is input, the external cold water flows into the water inlet interface 121 and is divided into two paths, one of which flows into the first water inlet channel 1111, and the other of which flows into the second water inlet channel 1121. When the water temperature is low, the electromagnetic valve closes the first channel 231, and the cold water flows from the second water inlet channel 1121 into the water outlet channel 1122, and then flows to the plate heat exchanger through the bathroom heat exchange interface 122 to exchange heat to form warm water for use by the user. In summer, when the water temperature is relatively high, the same amount of gas is sufficient to heat the water to a very high temperature, at which time the first channel 231 is opened by the electromagnetic valve to increase the flow, and part of the cold water in the second water inlet channel 1121 directly enters the water outlet channel 1122 through the second channel 132, and the other part of the cold water enters the water outlet channel 1122 through the first channel 231. At the same time, the cold water in the first water inlet channel 1111 also enters the water outlet channel 1122 through the first channel 231, and the cold water from the several paths eventually converges in the water outlet channel 1122, and finally flows to the cold water channel of the plate heat exchanger through the bathroom heat exchange interface 122 to exchange heat to form warm water, thereby achieving an increase in the water outlet flow and avoiding the water temperature after heating being too high to scald the user.

[0057] Optionally, as shown in Figure 5 and Figure 6As shown, the second channel 232 is provided with a limiting table 234 on the circumferential side, and the water outlet end of the flow limiting ring 24 abuts against the limiting table 234. The flow limiting ring 24 is limited by the limiting table 234, so that the flow limiting ring 24 can be firmly arranged in the second channel 232, preventing the flow from impacting the flow limiting ring 24 to move, and the limiting table 234 does not interfere with the first channel 231 and the second channel 232, and the bottom end of the flow limiting ring 24 is supported by the convex edge at the junction of the valve cavity 115 and the communication cavity 116 to prevent it from falling off.

[0058] In the embodiment, as shown in Figure 5 two limiting tables 234 are arranged in the second channel 232, and the two limiting tables 234 are respectively located on both sides of the water outlet 233, and the two limiting tables 234 simultaneously limit the flow limiting ring 24, so that the flow limiting ring 24 is uniformly stressed and can be firmly fixed in the second channel 232, preventing the flow from impacting the flow limiting ring 24 to move. In other embodiments, the number of limiting tables 234 can also be arranged as three, four or more in the circumferential direction, which can be flexibly arranged according to actual needs, and is not specifically limited here.

[0059] As shown in Figure 6 the valve seat 23 is provided with an arc-shaped partition 235, and the arc-shaped partition 235 divides the inner cavity of the valve seat 23 into the first channel 231 and the second channel 232 arranged adjacent to each other. Specifically, the cross section of the second channel 232 is circular, and the cross section of the first channel 231 is crescent shape surrounding part of the second channel 232, and the first channel 231 and the second channel 232 together constitute a pipeline with a circular cross section. In this way, on the basis of ensuring the water inflow of the first channel 231 and the second channel 232, the structure is more compact and small.

[0060] Further, as shown in Figure 3 and Figure 4As shown, the top end of the valve seat 23 is provided with a containing cavity 236, the cavity bottom of the containing cavity 236 is provided with a first communication port 237 in communication with the first channel 231 and a second communication port 238 in communication with the water outlet 233, the first communication port 237 surrounds the outer periphery of part of the second communication port 238, the second communication port 238 is located on the upper side of the second channel 232, one end of the electromagnetic coil 21 and the obturator 22 are located in the containing cavity 236, and the sealing gasket 222 of the obturator 22 can simultaneously open or close the first communication port 237 and the second communication port 238. When the sealing gasket 222 seals and closes the first communication port 237 and the second communication port 238, a cutoff is formed between the first channel 231 and the water outlet 233, at which time only the second channel 232 is used for water replenishment.
