In addition, those skilled in the art can combine and combine different embodiments or examples described in this specification and the features of different embodiments or examples without contradiction.
[0047] like Figure 1 As shown, the present invention provides a hot water supply system 100, including a water terminal 110, a water supply device 170, and a water storage tank 120. It should be noted that the water terminal 110 can be an object that requires water, such as a washbasin or a showerhead. The water terminal 110 can output warm water, cold water, or hot water to meet water needs in different scenarios.
[0048] The water supply device 170 is connected to the water terminal 110 and is used to provide hot or cold water to the water terminal 110. The water storage tank 120 is located between the water terminal 110 and the water supply device 170. The distance between the water storage tank 120 and the water terminal 110 is shorter than the distance between the water storage tank 120 and the water supply device 170. The water storage tank 120 is used to provide hot water to the water terminal 110. In this way, when the hot water in the water supply device 170 is consumed due to long-distance transportation, the water storage tank 120 can replenish the hot water to the water terminal 110 in a timely manner. The water storage tank 120 is located between the water terminal 110 and the water supply device 170 and is closer to the water terminal 110. In this way, the water flow path from the water storage tank 120 to the water terminal 110 is shorter, reducing the heat loss of the hot water during transportation, thereby improving the efficiency of hot water use. The water supply equipment 170 is prone to heat consumption when transporting hot water over long distances. When the long-distance hot water supply is insufficient, the water storage tank 120 can quickly provide hot water, ensuring a stable water supply to the water terminal 110 and improving user comfort and satisfaction.
[0049] According to the hot water supply system 100 proposed in the present invention, a water storage tank 120 that can provide hot water to the water terminal 110 is set between the water terminal 110 and the water supply equipment 170, and the water flow path from the water storage tank 120 to the water terminal 110 is short, which reduces the heat loss of hot water during the transportation process, thereby improving the use efficiency of hot water, ensuring stable water supply to the water terminal 110, and improving the comfort and satisfaction of users.
[0050] like Figure 1-Figure 3As shown, in one embodiment of the present invention, the hot water supply system 100 further includes a valve body 130, which is disposed between the water storage tank 120 and the water terminal 110. The valve body 130 connects the cold water channel with the water storage tank 120, mixes the hot water and the cold water to form warm water, and supplies the water terminal 110. By mixing the cold water and the hot water, the outlet water temperature can be controlled to ensure that the user obtains a suitable water temperature, avoiding the risk of scalding caused by excessively high water temperature or discomfort caused by excessively low water temperature. The user can adjust the water temperature at any time through the valve body 130 according to actual needs to adapt to different usage scenarios and needs, such as bathing, washing, etc., to conveniently meet various daily water needs.
[0051] Furthermore, continuous use of high-temperature hot water may adversely affect the water terminal 110 and the piping system, such as shortening equipment life or increasing pipeline pressure. Mixing water temperatures can extend equipment life and reduce maintenance requirements. Providing cold water, hot water, and mixed warm water in the same system increases system versatility and reduces the need for additional systems and equipment.
[0052] like Figure 2 and Figure 3 As shown, in some embodiments of the present invention, the hot water supply system 100 further includes a main hot water pipeline 140, a cold water pipeline 150, and a constant temperature water pipeline 160. The main hot water pipeline 140 is connected to the water storage tank 120 and is used to provide hot water to the water storage tank 120. The water storage tank 120 can be made of an insulating material to insulate the water in the water storage tank 120, reducing heat loss and achieving a good insulation effect. This improves the overall hot water utilization efficiency, allowing the water storage tank 120 to stably provide hot water to the water terminal 110. The main hot water pipeline 140 is connected to the valve body 130 and can provide hot water to the valve body 130. The cold water pipeline 150 connects the water terminal 110 and the valve body 130 and can provide cold water to both the water terminal 110 and the valve body 130. The constant temperature water line 160 connects the water terminal 110, the water storage tank 120, and the valve body 130. This allows water in the water storage tank 120 to flow through the constant temperature water line 160 to the water terminal 110, and the mixed warm water in the valve body 130 can also flow through the constant temperature water line 160 to the water terminal 110. This constant temperature water line 160 ensures that the system provides water at a constant temperature, thus avoiding the discomfort caused by water temperature fluctuations. Users can enjoy a stable supply of warm water, enhancing their comfort.
[0053] like Figure 2As shown, in some embodiments of the present invention, the valve body 130 includes a switching valve 131 and a thermostatic valve 135. The switching valve 131 is connected to the main hot water pipeline 140 and the cold water pipeline 150. The switching valve 131 switches between a hot water outlet state and a cold water outlet state. When the switching valve 131 is in the hot water outlet state, the switching valve 131 can provide hot water. When the switching valve 131 is in the cold water outlet state, the switching valve 131 can provide cold water. The thermostatic valve 135 is connected to the switching valve 131, and the thermostatic valve 135 is connected to the water storage tank 120 and the constant temperature water pipeline 160. When the switching valve 131 is outputting hot water, the hot water can directly pass through the thermostatic valve 135, enter the constant temperature water pipeline 160, and enter the water terminal 110. If the hot water temperature is too high, for example, when the hot water temperature exceeds the threshold value of the safe temperature for human contact, the switching valve 131 will automatically switch to the cold water outlet state, the switching valve 131 discharges cold water, and the cold water enters the thermostatic valve 135. At this time, the hot water in the water storage tank 120 enters the thermostatic valve 135 and mixes with the cold water, so that the thermostatic valve 135 can output warm water of a suitable temperature to the water terminal 110.
[0054] In this way, the combination of the switching valve 131 and the thermostatic valve 135 can regulate the water temperature in real time, ensuring that the output water temperature is within a safe threshold range. This system can respond to the user's demand for hot or cold water, while also providing constant temperature warm water. Regardless of whether the user chooses hot water, cold water, or warm water, they can quickly obtain the required water temperature, improving the user's experience. In addition, the design of the switching valve 131 and the thermostatic valve 135 can quickly adjust the water flow to the required temperature, reducing user waiting time and improving the system's response speed. Users do not need to wait for a long time to obtain water at the required temperature, which improves usage efficiency.
[0055] Or, in other embodiments, Figure 3 As shown, the valve body 130 is a switching valve 131, which has a hot water inlet 132, a cold water inlet 133, and a constant temperature water outlet 134. The switching valve 131 can switch the water path. For example, when the temperature of the hot water is lower than the threshold of the safe temperature for human contact, the switching valve 131 can open the hot water inlet 132 and close the cold water inlet 133. At this time, the switching valve 131 can stably provide hot water. When the temperature of the hot water is higher than the threshold of the safe temperature for human contact, the switching valve 131 opens the cold water inlet 133 and closes the hot water inlet 132. At this time, the switching valve 131 provides cold water. The cold water provided by the switching valve 131 and the hot water output from the water storage tank 120 are mixed at the constant temperature water outlet 134, thereby providing constant temperature water to the water terminal 110.
[0056] like Figure 4 and Figure 5As shown, in some embodiments of the present invention, the switching valve 131 includes a valve body 1311 and a valve core 1312. The valve body 1311 has a cold water inlet section 1313 and a hot water inlet section 1314 that are connected. The valve core 1312 is disposed within the cold water inlet section 1313 and the hot water inlet section 1314. The valve core 1312 is movable between the cold water inlet section 1313 and the hot water inlet section 1314 to switch the valve core 1312 between a hot water outlet position and a cold water outlet position. When the valve core 1312 is in the hot water outlet position, the valve core 1312 blocks the cold water inlet section 1313, and the hot water inlet section 1314 is open. At this time, the switching valve 131 is in a hot water outlet state. When the valve core 1312 is in the cold water outlet position, the valve core 1312 blocks the hot water inlet section 1314, and the cold water inlet section 1313 is open. At this time, the switching valve 131 is in a cold water outlet state.
[0057] When hot water is not needed, the switching valve 131 can quickly block the hot water inlet section 1314 to prevent unnecessary hot water consumption and heat energy loss. Accordingly, the switching valve 131 can open the hot water supply only when the user needs hot water, which helps to save energy and reduce operating costs. Due to the simple structure, the maintenance and replacement of the valve body 130 and the valve core 1312 are relatively convenient, reducing the maintenance cost and complexity of the system. The simplification of the overall structure also helps to extend the service life of the various components of the system. When the hot water temperature is too high, the valve core 1312 can quickly switch to the cold water inlet section 1313 to prevent the risk of scalding. This fast-response switching can effectively protect the safety of the user. The valve core 1312 moves between different water inlet sections to prevent direct mixing of cold water and hot water. This can avoid water flow interference and ensure that the system does not experience temperature fluctuations or instability during the switching process.
[0058] like Figure 4 and Figure 5 As shown, in some embodiments of the present invention, the switching valve 131 further includes a water outlet pipe 1315. The cold water inlet section 1313 is disposed opposite the hot water inlet section 1314, and the water outlet pipe 1315 is disposed between the cold water inlet section 1313 and the hot water inlet section 1314. In the design of the hot water supply system 100, the switching valve 131 includes the water outlet pipe 1315, and the cold water inlet section 1313 and the hot water inlet section 1314 are disposed opposite each other, with the water outlet pipe 1315 located therebetween. This makes the water flow path more intuitive and concise, reduces water flow circuitry and confusion, and improves the efficiency and stability of water flow switching.
[0059] Furthermore, valve core 1312 only needs to move a short distance between cold water inlet section 1313 and hot water inlet section 1314 to switch between cold and hot water. This rapid switching mechanism further reduces user waiting time and improves system responsiveness. The direct and symmetrical water inlet design reduces pressure loss in the system. This not only increases the water flow rate but also better maintains stable water pressure, enhancing the user experience.
[0060] The simple structure makes the valve body 130 and its components easy to maintain and inspect. The obvious position of the water outlet pipe 1315 also makes it convenient for users to perform troubleshooting and maintenance operations on the valve body 130, reducing maintenance costs. The simplified water flow channel reduces potential blockages and friction losses, increasing the durability and reliability of the system. Since the cold water inlet section 1313 and the hot water inlet section 1314 are arranged relative to each other, and the water outlet pipe 1315 is between the cold water inlet section 1313 and the hot water inlet section 1314, the cold water and hot water will not mix directly, which can avoid water temperature fluctuations and instability. This arrangement ensures precise control of constant temperature water output and improves user satisfaction with the water temperature.
[0061] like Figures 1 to 3 As shown, in some embodiments of the present invention, the water storage tank 120 is equipped with a heater 121. This heater 121 can directly heat the water within the water storage tank 120, allowing the water storage tank 120 to provide hot water more quickly. Even if the hot water supply from the water supply device 170 is consumed due to long-distance transportation, the heater 121 within the water storage tank 120 ensures that the water within the water storage tank 120 maintains the desired temperature. Furthermore, the heater 121 within the water storage tank 120 maintains the water temperature, providing a stable supply of hot water to the water terminal 110 at all times. Regardless of changes in the external water supply, the water temperature within the water storage tank 120 remains relatively stable, providing users with a continuous supply of hot water. This eliminates the need for users to wait for long periods of time for hot water. Even during peak water usage periods, the heater 121 can provide the required hot water in real time, improving the user experience and meeting the needs of various application scenarios. During peak water use periods or when the long-distance water supply equipment 170 is insufficient in heat supply, the heater 121 in the water storage tank 120 can quickly replenish heat, flexibly respond to the peak demand of the water terminal 110, and prevent insufficient hot water supply.
[0062] In some embodiments of the present invention, the water tank 120 is also equipped with a temperature control device (not shown), which is electrically connected to the heater 121. The temperature control device can detect the water temperature within the water tank 120. For example, if the temperature control device detects that the water temperature within the water tank 120 is too low, the temperature control device can control the heater 121 to heat the water within the water tank 120. When the water temperature reaches a preset value, the heater 121 stops heating. In this way, the heater 121 and the temperature control device can precisely adjust and maintain the water temperature, ensuring that the water temperature remains within a comfortable and safe range. This automatic temperature control function further enhances the intelligence and convenience of the system and improves the user experience.
[0063] like Figure 1-Figure 3 As shown, in some embodiments of the present invention, the valve body 130 can be a solenoid valve or an electronic valve. Both the solenoid valve and the electronic valve can be connected to an intelligent control system, allowing users to automatically open and close the solenoid valve or electronic valve as needed to adjust the water flow. This can increase the degree of automation of the system, allowing users to control the water supply system through a remote control, smartphone application, or central control panel.
[0064] Solenoid valves and electronic valves feature fast switching, enabling them to respond to control signals instantly and change water flow paths or temperature settings, improving system responsiveness and efficiency. Solenoid valves and electronic valves can integrate temperature and flow sensors for real-time monitoring and automatic protection. For example, if the system detects excessive water temperature or abnormal flow, it can automatically close the valve to prevent burns or damage to equipment.
[0065] In some embodiments of the present invention, the hot water supply system 100 is further equipped with a filter device (not shown), which is connected to the valve body 130. The filter device effectively removes impurities, particles, sediment, chlorine, and other harmful substances from the water, ensuring that the water supply system provides clean, healthy water. Whether hot or cold water, the water quality is improved after passing through the filter device. Furthermore, the filter device protects the valve body 130, heater 121, and other pipeline components at the rear end, reducing equipment wear and failure caused by factors such as scale accumulation, thereby extending the service life of these components.
[0066] Finally, it should be noted that the above embodiments are intended only to illustrate the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art will appreciate that various combinations, modifications, or equivalent substitutions of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention and are intended to be encompassed by the claims of the present invention.
