Description

Technical Field

[0001] The utility model relates to the technical field of domestic water, in particular to a hot water supply system. Background Art

[0002] In the prior art, a hot water pipe of varying lengths is connected between the hot water source of various hot water devices and the water-using device terminal. Since the thermal insulation of the hot water pipe is poor, after turning on the faucet, the user must wait for some cold water to flow out before hot water can flow out of the faucet. The user must use his hand to test when hot water will flow out at any time. If the user wants to use hot water in a cold environment, the hot water device will cause them great trouble.

[0003] In order to realize a zero cold water hot water supply system, in the prior art, a return water pipeline is usually provided between the water heater of the hot water equipment and the terminal of the water-using equipment, and a circulation pump is provided on the return water pipeline. When the temperature of the water in the hot water pipeline drops to a preset temperature, the circulation pump can pump the water with a lower temperature in the hot water pipeline back into the water heater for heating, and the hot water with a higher temperature in the water heater can flow into the hot water pipeline for user use. However, when using this hot water equipment, the circulation pump needs to work continuously, which consumes a lot of power and makes a lot of noise. In addition, as the length of the water pipe at the user end increases, the return water circulation time becomes longer, and the heat loss of the pipe becomes larger, which leads to a serious drop in the temperature of the hot water.

[0004] Therefore, it is urgent to propose a hot water supply system to solve the above problems. Utility Model Content

[0005] Based on the above, the purpose of the utility model is to provide a hot water supply system, which can achieve the effects of stable water temperature at the water outlet terminal of the water-using equipment, low energy consumption and low noise.

[0039] Embodiment 1

[0040] Figure 1 FIG. 2 shows a schematic diagram of the structure of the hot water supply system provided in this embodiment. Figure 1As shown, this embodiment provides a hot water supply system, which includes a water heater body 100, a water-using device terminal 200, a connecting pipe 300 and a constant temperature component 400. The water heater body 100 is configured to heat water therein; the two ends of the connecting pipe 300 are respectively connected to a first hot water outlet 101 of the water heater body 100 and a first hot water inlet 201 of the water-using device terminal 200; the constant temperature component 400 is arranged on the connecting pipe 300, and the constant temperature component 400 includes a constant temperature valve 401 and a kitchen treasure 402 which are sequentially arranged along the water flow direction in the connecting pipe 300.

[0041] In the hot water supply system provided in this embodiment, when the user turns on the water-using equipment terminal 200, the kitchen treasure 402 can supply hot water at any time. When the water temperature in the kitchen treasure 402 drops, the hot water in the water heater body 100 can pass through the thermostatic valve 401 and then flow through the kitchen treasure 402 to the water outlet of the water-using equipment terminal 200 for use by the user. Only the water temperature in the section of the connecting pipe 300 from the kitchen treasure 402 to the water outlet of the water-using equipment terminal 200 is low, but compared with the entire connecting pipe 300, the water volume is small, which can greatly reduce the time for emptying the cold water and save water. The hot water supply system can achieve the effect of stabilizing the water temperature of the water outlet of the water-using equipment terminal 200, and omits the use of a circulating pump that needs to work continuously, with low energy consumption and low noise, which can improve the user experience.

[0042] It is understandable that when installing the hot water supply system, the kitchen treasure 402 can be placed as close to the water-using equipment terminal 200 as possible to reduce the length of a section of the connecting pipe 300 from the kitchen treasure 402 to the water outlet of the water-using equipment terminal 200, and further reduce the time and volume of cold water to be emptied. Optionally, the connecting pipe 300 is provided with an insulation layer at a position between the kitchen treasure 402 and the water-using equipment terminal 200 to reduce the cooling rate of the water in the section of the connecting pipe 300 from the kitchen treasure 402 to the water outlet of the water-using equipment terminal 200.

[0043] In actual use, the heating temperature of the water by the kitchen treasure 402 can be made the same as the set temperature of the thermostatic valve 401, so that when the hot water in the water heater body 100 passes through the thermostatic valve 401 and then flows to the water outlet of the water-using equipment terminal 200 through the kitchen treasure 402, the kitchen treasure 402 will not be started, so as to avoid power consumption caused by frequent startup of the kitchen treasure 402.

[0044] It should be noted that the thermostatic valve 401 is a relatively mature technology in the prior art, and the specific structure of the thermostatic valve 401 is not described in detail in this embodiment.

[0045] In this embodiment, the kitchen treasure 402 is a storage water heater. The capacity of a storage water heater is usually 5L to 15L, which can realize the function of storing hot water in a small volume so that users can use hot water at any time. It is easy to install and has low cost. Of course, in other embodiments, the kitchen treasure 402 can also be an instant electric water heater. The instant electric water heater is small in size, small in installation space, fast in heating speed, high in thermal efficiency, and energy-saving.

[0046] In this embodiment, the water heater body 100 is a heat pump water heater. The heat pump water heater has the advantages of high efficiency and energy saving, safety and reliability, long durability, large water volume, wide application range, long-term constant temperature, safety and environmental protection, and easy installation. The water heater body 100 is also provided with a second cold water inlet 103, which is connected to the external water source 10 to supply cold water to the water heater body 100.

[0047] Optionally, there are multiple water-using equipment terminals 200, and each water-using equipment terminal 200 corresponds to a connecting pipe 300 and a thermostatic component 400. Multiple water-using equipment terminals 200 are usually installed in each household, such as showers or faucets. In order to meet the user's demand for hot water, a thermostatic component 400 can be set on the connecting pipe 300 between each water-using equipment terminal 200 and the water heater body 100, so that only one water heater body 100 is installed in the household to achieve the effect of hot water supply for the whole house. Of course, during installation, the installer can also ask the user's needs and only set the thermostatic component 400 on part of the connecting pipe 300 to reduce the installation cost and use cost.

[0048] When the user turns off the water-using equipment terminal 200 to stop the output of hot water, the hot water in the connecting pipe 300 will breed a large number of bacteria in the hot water temporarily stored in the connecting pipe 300 because the temperature is suitable for bacterial growth. When the user turns on the water-using equipment terminal 200 again, bacteria will exist in the first section of water that flows out. In order to solve this problem, in this embodiment, the hot water supply system also includes a sterilization module, which is arranged on the connecting pipe 300 and is used to sterilize the water in the connecting pipe 300, thereby reprocessing the water contaminated by bacterial growth in the connecting pipe 300, thereby improving the user's water quality and experience.

[0049] In some embodiments, the sterilization module may be an ultraviolet sterilizer, which is used to perform ultraviolet sterilization on the water flowing into the connecting pipe 300. Specifically, the ultraviolet sterilizer mainly uses ultraviolet rays generated by an ultraviolet lamp to sterilize the flowing water, and the ultraviolet lamp may be a device capable of generating ultraviolet rays, such as an ultraviolet LED lamp.

[0050] In other embodiments, the sterilization module may be an ozone sterilizer, which is used to perform ozone sterilization on the water flowing into the connecting pipe 300. Specifically, the ozone generated by the ozone sterilizer enters the water flow to sterilize the bacteria in the water flow.

[0051] Of course, in some other embodiments, an ultraviolet sterilizer and an ozone sterilizer may be simultaneously provided on the connecting pipeline 300; or an ultraviolet sterilizer may be provided on part of the connecting pipeline 300, and an ozone sterilizer may be provided on part of the connecting pipeline 300, both of which may achieve the above effects.

[0052] Embodiment 2

[0053] Figure 2 FIG. 2 shows a schematic diagram of the structure of the hot water supply system provided in this embodiment. Figure 2 As shown, this embodiment provides a hot water supply system, which includes a water heater body 100, a water-using device terminal 200, a connecting pipe 300 and a thermostat assembly 400. The water heater body 100 is configured to heat the water therein; the two ends of the connecting pipe 300 are respectively connected to the first hot water outlet 101 of the water heater body 100 and the first hot water inlet 201 of the water-using device terminal 200; the thermostat assembly 400 is arranged on the connecting pipe 300, and the thermostat assembly 400 includes a thermostat valve 401 and a kitchen treasure 402 arranged in sequence along the water flow direction in the connecting pipe 300. When the user turns on the water-using device terminal 200, the kitchen treasure 402 can supply hot water at any time. When the water temperature in the kitchen treasure 402 drops, the hot water in the water heater body 100 can flow through the thermostat valve 401 and then through the kitchen treasure 402 to the water outlet of the water-using device terminal 200 for use by the user. Only the water in the section of the connecting pipe 300 from the kitchen treasure 402 to the water outlet of the water-using equipment terminal 200 has a low temperature, but compared with the entire connecting pipe 300, the water volume is small, which can greatly reduce the time for draining cold water and save water. The hot water supply system can achieve the effect of stabilizing the water temperature of the water outlet of the water-using equipment terminal 200, and omits the use of a circulating pump that needs to work continuously, has low energy consumption and low noise, and can improve the user experience.

[0054] The hot water supply system provided in this embodiment has a substantially similar structure to that of the hot water supply system in Embodiment 1, except that the hot water supply system provided in this embodiment further includes a backup constant temperature structure 500, which is used to enable the hot water supply system to achieve an almost zero cold water effect when the constant temperature component 400 fails.

[0055] Specifically, the standby thermostatic structure 500 includes a standby return water pipeline 501, a circulation pump 502 and a standby water pipeline 503. The two ends of the standby water pipeline 503 are respectively connected to the second hot water outlet 104 of the water heater body 100 and the second hot water inlet 202 of the water-using equipment terminal 200; the two ends of the standby return water pipeline 501 are respectively connected to the first cold water inlet 102 of the water heater body 100 and one end of the standby water pipeline 503 close to the water-using equipment terminal 200; the circulation pump 502 is arranged on the standby return water pipeline 501, and is used to pump the water in the standby water pipeline 503 into the water heater body 100. When the thermostatic component 400 fails, the standby thermostatic structure 500 can be started so that the circulation pump 502 pumps the water with a lower temperature in the standby water pipeline 503 into the water heater body 100 for reheating, so as to temporarily meet the user's demand for hot water.

[0056] Optionally, a switch valve is provided on the standby water pipe 503 and / or the standby return pipe 501. Under normal circumstances, the switch valve is normally closed, and the standby constant temperature structure 500 is not enabled to save energy. When the constant temperature component 400 fails and has not been repaired in time, the user can first start the standby constant temperature structure 500 and open the switch valves on the standby water pipe 503 and the standby return pipe 501 to temporarily meet the user's demand for hot water.

[0057] The standby thermostatic structure 500 also includes a temperature detection component, which is disposed at the outlet of the kitchen treasure 402 and is used to detect the temperature of the water at the outlet of the kitchen treasure 402. If the temperature of the water flowing out of the outlet of the kitchen treasure 402 is continuously low for a period of time, it indicates that the thermostatic component 400 has failed. The control module of the hot water supply system can first start the standby thermostatic structure 500 and alarm the user to remind the user that the thermostatic component 400 has failed, so as to remind the user to repair the thermostatic component 400 in time.

[0058] Note that the above are only preferred embodiments of the present invention and the technical principles used. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments and substitutions can be made by those skilled in the art without departing from the scope of protection of the present invention. Therefore, although the present invention is described in more detail through the above embodiments, the present invention is not limited to the above embodiments, and may include more other equivalent embodiments without departing from the concept of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
