[0042] An electric water heater is a common household water heating device that uses electricity to heat tap water or water of suitable quality to a set temperature for daily use. It can usually be divided into a water tank and water system, a heating element, and a heating control system. The water system is responsible for transporting and storing hot water, while the heating system is responsible for heating cold water to a set temperature.

[0043] In the related art, as the functions of the water heater increase, the number of components such as valves in the corresponding water system increases, which increases the number of connected nodes in the water system and increases the complexity of the water system, which increases the risk of water leakage in the water system and reduces the stability of the water system.

[0044] Regarding the problems in related technologies, such as Figure 1 , Figure 2As shown, in the embodiment of the utility model, a water circuit assembly is provided, including a housing 100, a thermostatic valve 200 and a water supply valve 300; a water inlet circuit 101, a cold water circuit 102, a water supply circuit 103, a hot water circuit 104 and a water supply circuit 105 are formed in the housing 100, the water inlet circuit 101 is used to input cold water, the cold water circuit 102 and the water supply circuit 103 are both connected to the water inlet circuit 101, and the hot water circuit 104 is used to input High-temperature hot water, the water circuit 105 is used to output constant temperature hot water, the thermostatic valve 200 is arranged on the outer shell 100, the cold water circuit 102 and the hot water circuit 104 are both connected to the input end of the thermostatic valve 200, and the output end of the thermostatic valve 200 is connected to the water circuit 105 to output constant temperature hot water through the thermostatic valve 200; the water replenishment valve 300 is arranged on the outer shell 100, and acts on the water replenishment circuit 103 to control the on-off of the water replenishment circuit 103. The water system can realize the transportation of cold water and hot water in the water tank of the water heater. When the user needs to use hot water, the high-temperature hot water is mixed with cold water to form a constant temperature hot water output. The cold water and hot water transportation process and the mixing process require the cooperation of valves, and the connection of valves will increase the connection nodes in the water system, thereby increasing the risk of water leakage. In this embodiment, by integrating the thermostatic valve 200 and the water supply valve 300 into the outer shell 100 and being able to communicate with the internal water circuit, the water system is simplified, the connection nodes of the valves are reduced, the risk of water leakage is reduced, and the stability of the water system is improved.

[0045] It is understandable that the water heater needs to continuously heat cold water to obtain high-temperature hot water during operation, and the high-temperature hot water needs to be mixed with cold water to achieve the output of constant-temperature hot water. During the continuous heating process, the water channel needs to continuously output hot water and transport cold water, which requires multiple valves to cooperate. Multiple valves have multiple connection nodes when connected, and the increase in connection nodes means an increase in the risk of water leakage. This embodiment integrates each valve into the shell in an integrated manner, and forms a water channel system by connecting with the water channel in the shell, which significantly reduces the connection nodes of the valves and reduces the risk of water leakage.

[0046] The housing 100 is used to form a plurality of water channels inside, and the plurality of water channels can realize the delivery and guidance of cold water and hot water. Specifically, the specific structural shape of the housing 100 is not limited in this embodiment, for example, the housing 100 can be a flat block structure, or a three-dimensional columnar structure.

[0047] The thermostatic valve 200 is used to mix the input high-temperature hot water with cold water, and realize constant-temperature water output by mixing the high-temperature hot water and cold water. Specifically, the specific structure of the thermostatic valve 200 is not limited in this embodiment. For example, the thermostatic valve 200 can be an electronic thermostatic valve 200 or a mechanical thermostatic valve 200.

[0048] The water replenishment valve 300 is used to control the on-off of the water replenishment waterway 103. When the water heater heats the cold water by indirect heating, the water in the water tank is in a continuous heating state. After heating for a period of time, the liquid level in the water tank will drop, and water replenishment needs to be performed regularly. When replenishing water, cold water enters the water tank through the water replenishment waterway 103. Specifically, the specific structure of the water replenishment valve 300 is not limited in this embodiment. For example, the water replenishment valve 300 can be a manually controlled valve body or an automatically controlled valve body.

[0049] In a specific implementation manner, the water inlet waterway 101, the cold water waterway 102, the water replenishment waterway 103, the hot water waterway 104 and the water use waterway 105 are all used to guide the transported water. Specifically, there is no limitation on the specific formation structure of each waterway, and each waterway can be a straight line shape, a curved shape, or a combined special-shaped structure.

[0050] In this embodiment, the specific process for transporting cold water and hot water is as follows: the input cold water is input through the water inlet waterway 101, a part of the cold water in the water inlet waterway 101 is output to the water tank through the waterway component for heating, a part of the cold water enters the water replenishment waterway 103, and the remaining part of the cold water enters the cold water waterway 102. The hot water waterway 104 is used to connect with the water tank and input high-temperature hot water. The high-temperature hot water and cold water are mixed through a thermostatic valve 200 to obtain constant-temperature hot water, and the constant-temperature hot water is output from the water-using waterway 105 to complete the transportation of hot water and cold water in the waterway system.

[0051] According to an embodiment of the present invention, a cold water inlet port 1301, a cold water interface 1101, a water replenishment interface 1103, a hot water interface 1102 and a water output port 1302 are provided on the housing 100; the cold water inlet port 1301 is connected to the cold water interface 1101 through the water inlet waterway 101, the water replenishment interface 1103 is connected to the water inlet waterway 101 through the water replenishment waterway 103, the hot water interface 1102 is connected to the thermostatic valve 200 through the hot water waterway 104, and the water output port 1302 is connected to the thermostatic valve 200 through the water waterway 105. When constructing the water system of the water heater, the waterway assembly needs to be connected to the external cold water end, the water end and the water tank of the water heater to realize the transportation of water. In this embodiment, by providing multiple interfaces on the housing 100, each interface is connected to the corresponding component or the corresponding connection end to realize the transportation of water by the waterway assembly. The multiple interfaces and ports are convenient for installation and subsequent maintenance and repair.

[0052] The following is a detailed description of each interface and port in this embodiment:

[0053] The cold water input port is used to connect to an external cold water source. The cold water input port can be easily connected to the external cold water source. Cold water enters the water inlet path 101 through the cold water input port, and the cold water is distributed and flows through the water inlet path 101. For example, a tap water pipe is connected to the cold water input port, so that tap water can enter the water inlet path 101 through the cold water input port to realize the process of heating cold water to hot water output.

[0054] The cold water interface 1101 is used to connect with the heating system in the water heater, and the cold water structure is connected with the water inlet 101, so that the cold water is heated by the heating system and outputs high-temperature hot water. For example, the cold water interface 1101 is connected to the cold water input end of the heat exchanger, and the heat exchanger is a heating component in the water heater. The tap water enters the cold water structure through the water inlet 101, and enters the heat exchanger in the water tank through the cold water interface 1101, and the tap water is heated by the heat exchanger.

[0055] The hot water interface 1102 is used to connect to the heating system in the water heater and communicate with the hot water circuit 104, so that the high-temperature hot water enters the hot water circuit 104 through the hot water interface 1102. For example, the hot water interface 1102 is connected to the output end of the heat exchanger, and the heated high-temperature hot water enters the hot water circuit 104 through the hot water interface 1102.

[0056] The water replenishment interface 1103 is used to connect with the water tank in the water heater, so that cold water enters the water tank through the water replenishment interface 1103, and the water in the water tank is heated to a high temperature through the heating system, and then the cold water entering through the cold water interface 1101 is heated to a high temperature through heat exchange and other methods. For example, tap water is diverted to the water replenishment water path 103 through the water inlet water path 101, and the cold water in the water replenishment water path 103 enters the water tank through the water replenishment interface 1103 to achieve water replenishment.

[0057] The water output port 1302 is used to connect to the user's end, and the water output port is connected to the water channel 105, so that constant temperature water can be output through the water output port. For example, the water output port 1302 is connected to a shower spray device, so that constant temperature hot water is output through the spray device.

[0058] In a specific implementation, the cold water interface 1101, the water replenishment interface 1103 and the hot water interface 1102 are all quick-connect interfaces protruding from one side of the housing 100. The three interfaces are respectively arranged on one side of the housing 100 to facilitate installation and connection. The cold water inlet port 1301 and the water outlet port 1302 are respectively protruding from one side of the housing 100, and the two ports are columnar structures.

[0059] According to an embodiment of the present invention, the input end of the thermostatic valve 200 includes a cold water input port and a hot water input port, the cold water input port is connected to the cold water circuit 102, and the hot water input port is connected to the hot water circuit 104. The thermostatic valve 200 is used to adjust the water temperature to achieve a predetermined constant water temperature. In this embodiment, the hot water and the cold water are connected through the two input ports on the thermostatic valve 200, which is convenient for installation.

[0060] It is understandable that, in this embodiment, the thermostatic valve 200 is integrated into the housing 100, and the water circuit is connected by providing an input port on the thermostatic valve 200. Specifically, Figure 2 Figure 3 As shown, the two input ports of the thermostatic valve 200 are respectively connected to the hot water circuit 104 and the cold water circuit 102, and the hot water and the cold water enter the thermostatic valve 200 to achieve mixed temperature adjustment. That is, when connecting, it is only necessary to make the two input ports of the thermostatic valve 200 correspond to the respective water circuits. Since the entire water circuit and the connection are all inside the housing 100, the risk of water leakage is further reduced and the stability of the water circuit system is improved.

[0061] In this embodiment, the specific connection method of the water circuit in the shell 100 is: the input end of the water inlet circuit 101 is connected to the cold water inlet port 1301, and the output end of the water inlet circuit 101 is connected to the cold water interface 1101; the input end of the cold water circuit 102 is connected to the water inlet circuit 101, and the output end of the cold water circuit 102 is connected to the input end of the thermostatic valve 200; the input end of the hot water circuit 104 is connected to the hot water interface 1102, and the output end of the hot water circuit 104 is connected to the input end of the thermostatic valve 200; the input end of the replenishment water circuit 103 is connected to the water inlet circuit 101, and the output end of the replenishment water circuit 103 is connected to the replenishment interface 1103; the input end of the water use circuit 105 is connected to the output end of the water thermostatic valve 200, and the output end of the water use circuit 105 is connected to the water output port 1302.

[0062] According to an embodiment provided by the utility model, Figure 3 , Figure 4 As shown, the housing 100 includes a first housing 110, a second housing 130 and a water divider 120. The first housing 110 is fixedly connected to the second housing 130. The water divider 120 is disposed between the first housing 110 and the second housing 130. The water divider 120 and the first housing 110 and the second housing 130 define a water inlet waterway 101, a cold water waterway 102, a water replenishment waterway 103, a hot water waterway 104 and a water use waterway 105. The housing has a plurality of waterways formed therein, and the plurality of waterways are used to transport and guide water, that is, a plurality of waterway channels need to be constructed inside the housing. In this embodiment, a plurality of waterways are formed by connecting the split structure, which reduces the complexity of forming each waterway and facilitates installation and maintenance.

[0063] In the specific setting, the first shell 110, the water diversion plate 120 and the second shell 130 are connected in a stacked manner. Specifically, the first shell 110 and the water diversion plate 120 are connected by hot melt welding, and the second shell 130 and the water diversion plate 120 are also connected by hot melt welding, thereby achieving a fixed connection of the entire shell 100 and being able to form multiple waterways in the formed shell 100.

[0064] It is understandable that the waterway in the housing 100 is used to guide and transport water, and the structure of the waterway needs to be smooth and accurate, otherwise it will affect the transportation of water. In this embodiment, the housing 100 is set to a split connection mode, and this split connection mode can be processed by a separate processing method and then assembled to form the housing 100, that is, the first housing 110, the water diversion plate 120 and the second housing 130 are processed separately and then connected. This method reduces the difficulty of processing and is conducive to assembly and later maintenance.

[0065] In a specific implementation, the first shell 110, the second shell 130 and the water diversion plate 120 are made of the same material. In a preferred example, PPR material or plastic material is used so that the housing 100 can act as an anti-electrical wall to reduce the risk of leakage. Of course, different materials can also be used for the first shell 110, the second shell 130 and the water diversion plate 120.

[0066] like Figure 3 As shown, in the specific configuration, the cold water interface 1101, the water replenishment interface 1103 and the hot water interface 1102 are all arranged on the first shell 110; the cold water inlet port 1301 and the water output port 1302 are both arranged on the second shell 130. The water circuit assembly is used to realize that the water heater is connected to the cold water input end and the hot water output end respectively. The cold water interface 1101, the water replenishment interface 1103 and the hot water interface 1102 are used to connect to the water heater. The multiple interfaces are arranged on one side of the same shell to facilitate the connection of each interface, and to facilitate installation and maintenance by the user. Similarly, the cold water inlet port 1301 and the water output port 1302 respectively realize the cold water input and the use of constant temperature hot water, and are connected on the same shell to facilitate installation and maintenance.

[0067] like Figure 3 , Figure 4As shown, in a specific embodiment, the first shell 110 and the second shell 130 both have an outer surface, wherein the outer surface of the first shell 110 is the upper surface, and the outer surface of the second shell 130 is the lower surface, and the cold water interface 1101, the water replenishment interface 1103, and the hot water interface 1102 are all arranged on the upper surface of the first shell 110, and the arrangement on the same surface improves the convenience of installation and is easy to maintain. The cold water inlet port 1301 and the water outlet port 1302 are both connected to the lower surface of the second shell 130, and the cold water inlet port 1301 and the water outlet port 1302 are both formed as a tubular structure protruding from the lower surface.

[0068] According to an embodiment of the present invention, the second housing 130 has a first installation port 1303 and a second installation port 1304 arranged at intervals. The first installation port 1303 is used for installing the thermostatic valve 200, and the second installation port 1304 is used for installing the water supply valve 300. For the installation of the thermostatic valve 200 and the water supply valve 300, it is necessary to reduce the nodes connected thereto, thereby reducing the risk of water leakage. In this embodiment, the thermostatic valve 200 and the water supply valve 300 are connected through two separate installation ports, which, on the one hand, reduces the connection nodes between the valve body and the waterway, and on the other hand, the connection position between the valve body and the waterway is located inside the housing 100, thereby reducing the risk of water leakage and improving the stability of the waterway system.

[0069] In a specific implementation manner, Figure 3 As shown, the first mounting port 1303 has a first mounting seat, the second mounting port 1304 has a second mounting seat, the first mounting seat and the second mounting seat have fixing screw holes, the first mounting seat has a first mounting cavity, the second mounting seat has a second mounting cavity, the first mounting cavity has three connecting holes, the three connecting holes correspond to the two input ports and one output port of the thermostatic valve 200, the second mounting cavity has a connecting hole, the water supply valve 300 is connected to the second mounting cavity, and controls the on-off of the water supply waterway 103. It can be understood that the main bodies of the thermostatic valve 200 and the water supply valve 300 are both connected to the mounting port by bolts, which is convenient for users to install and maintain.

[0070] According to an embodiment of the present invention, a water inlet channel 1104, a cold water flow channel 1105 and a water replenishment flow channel 1106 are provided on the inner wall of the first shell 110, and the water inlet channel 1104 is connected with the cold water flow channel 1105 and the water replenishment flow channel 1106; a hot water flow channel 1305 and a water use flow channel 1306 are provided on the inner wall of the second shell 130; the water dividing plate 120 cooperates with the water inlet channel 1104 to form a water inlet waterway 101; the water dividing plate 120 cooperates with the cold water flow channel 1105 to form a cold water waterway 102; the water dividing plate 120 cooperates with the water replenishment flow channel 1106 to form a water replenishment waterway 103; the water dividing plate 120 cooperates with the hot water flow channel 1305 to form a hot water waterway 104; the water dividing plate 120 and the water use flow channel 1306 form a water use waterway 105. The internal space of the outer shell 100 is mainly used to construct a water channel and realize water transportation through the water channel. In this embodiment, different water channels are formed by the cooperation between the water dividing plate 120 and the first shell 110 and the second shell 130. This method allows each water channel to be closely arranged in the space above and below the water dividing plate 120, making the overall structure of the water channel assembly more compact.

[0071] In a specific embodiment, Figure 3 , Figure 4 As shown, the first shell 110 is located above the water dividing plate 120, and the second shell 130 is located below the water dividing plate 120. The space above the water dividing plate 120 forms an inlet waterway 101, a cold water waterway 102 and a replenishing waterway 103, wherein the inlet waterway 101 realizes the input of cold water into hot water through the cold water interface 1101, wherein the cold water waterway 102 and the replenishing water waterway 103 are both connected to the inlet waterway 101, and the space below the water dividing plate 120 forms a hot water waterway 104 and a water waterway 105, and the hot water waterway 104 and the water waterway 105 are respectively connected to the first installation port 1303, that is, they are both connected to the thermostatic valve 200.

[0072] It is understandable that the upper space and the lower space of the water diversion plate 120 form different water channels respectively, which is beneficial to the arrangement of the water channels, avoids mutual interference between independent water channels, and makes the structure of the entire water channel assembly more compact.

[0073] In a specific implementation, the water divider plate 120 is provided with a connecting notch 1204, a first flow hole 1201, and a second flow hole 1202. The cold water inlet port 1301 is connected to the water inlet cavity 1104 through the first flow hole 1201, the hot water interface 1102 is connected to the hot water flow cavity 1305 through the second flow hole 1202, and the input end of the thermostatic valve 200 is connected to the cold water flow cavity 1105 through the connecting notch 1204. The water divider plate 120 divides different waterways into two layers, which can improve the compactness of the overall structure. When the waterway flows, it needs to enter different waterways through the water divider plate 120. In this embodiment, the connection with different waterways is achieved through the flow holes and the connecting notch 1204, which is convenient for installation and maintenance.

[0074] like Figure 3 , Figure 4 As shown, the communication gap 1204 is used to connect the cold water flow channel 1105 with the first installation port 1303, so that cold water can enter the thermostatic valve 200 at the first installation port 1303 from the cold water flow channel 1105. The first flow hole 1201 is used to connect the water inlet channel 1104 with the cold water inlet port 1301, and the second flow hole 1202 is used to connect the hot water interface 1102 with the hot water flow channel 1305.

[0075] According to an embodiment provided by the utility model, Figure 3 As shown, the water distribution plate 120 is further provided with a third flow hole 1203, and the corresponding second shell 130 is provided with a buffer cavity 1307, and the buffer cavity 1307 is connected with the water replenishment flow cavity 1106 through the third flow hole 1203. When cold water is passed into the water replenishment flow cavity 1106, there is a certain water pressure. In this embodiment, the third flow hole 1203 is provided, so that the cold water can buffer the water pressure through the buffer cavity 1307 when entering the water replenishment interface 1103, thereby improving the stability of the device.

[0076] The specific flow process of water in the water channel assembly is as follows: cold water enters from the bottom through the cold water inlet port 1301, and then enters the water inlet channel 1104 through the first flow hole 1201. A part of the water in the water inlet channel 1104 enters the first installation port 1303, i.e., the thermostatic valve 200, through the cold water flow channel 1105, a part of the water is input into the water replenishment interface 1103 through the water replenishment flow channel 1106, and the remaining part is directly input into the cold water interface 1101. The high-temperature hot water heated by the water heater is input into the hot water flow channel 1305 through the hot water interface 1102, and enters the first installation port 1303, i.e., the thermostatic valve 200, through the hot water flow channel 1305. At this time, the cold water and the high-temperature hot water are mixed to obtain constant temperature hot water, and then input into the water output port 1302 through the water flow channel. Among them, when the cold water enters the water body on one side of the water replenishment flow channel 1106, it buffers the flowing water through the third flow hole 1203, thereby improving the stability of the device.

[0077] like Figure 4 As shown, in a specific example, a hot water flow matching cavity 1205 and a water flow matching cavity 1206 are constructed on the water dividing plate 120, wherein the hot water flow matching cavity 1205 is consistent in structure with the hot water flow cavity 1305, and the water flow matching cavity 1206 is consistent in structure with the water flow cavity 1306, so that a hot water waterway 104 and a water waterway 105 are formed after the water dividing plate 120 and the second shell 130 are matched.

[0078] According to an embodiment of the present invention, the water circuit assembly further includes a temperature sensor 400 and / or a water flow sensor 500, and the temperature sensor 400 and the water flow sensor 500 are both electrically connected to the thermostatic valve 200; wherein the temperature sensor 400 is connected to the housing 100 and is located on the water circuit 105, and the water flow sensor 500 is connected to the housing 100 and is located on the water inlet circuit 101. Usually, the water end needs to use mixed constant temperature hot water, and the output water temperature can be adjusted by adjusting the mixing amount of cold water. In this embodiment, the water temperature of the output water can be detected by the temperature sensor 400, and the detected water temperature can be fed back to adjust the amount of cold water input into the thermostatic valve 200, thereby achieving accurate temperature control.

[0079] It is understandable that the thermostatic valve 200 can be automatically controlled by the electrical connection between the temperature sensor 400, the water flow sensor 500 and the thermostatic valve 200. For example, when the temperature needs to be increased, the amount of cold water entering the thermostatic valve 200 is reduced through the detection of the water flow sensor 500, thereby increasing the temperature. Similarly, when a lower output temperature is required, the amount of cold water entering the thermostatic valve 200 is increased through the detection of the water flow sensor 500, thereby reducing the temperature. Whether the temperature reaches the predetermined temperature can be obtained through the real-time feedback of the temperature sensor 400, thereby improving the accuracy of temperature control.

[0080] Another aspect of the utility model provides a water heater, comprising a water heater body; the water heater body is connected to any of the water channel components described in the above embodiments.

[0081] Through the description of the above embodiments, technicians in this field can clearly understand that each embodiment integrates the thermostatic valve 200 and the water supply valve 300 into the housing 100, thereby reducing the connection nodes between the valve body and the pipeline, thereby reducing the leakage points, making the probability of water leakage in the water path component lower and making the water path system more stable.
