Some specific embodiments of the invention will be described in detail hereinafter, by way of illustration and not limitation, with reference to the accompanying drawings. The same reference numbers in the drawings identify the same or similar elements or components. Those skilled in the art will appreciate that the drawings are not necessarily to scale. In the drawings:
FIG. 1 is a schematic view of a water supply system according to one embodiment of the present invention.
Detailed Description
FIG. 1 is a schematic view of a water supply system according to one embodiment of the present invention. As shown in fig. 1, the present embodiment provides a water supply system 10, and the water supply system 10 includes a hot water pipe 110, a first pressure sensor 111, a first normal temperature water pipe 120, a second pressure sensor 121, a water outlet device 200, and a water pressure adjusting part. Wherein the water pressure adjusting part includes a first throttle valve 112 and a second throttle valve 122.
The hot water pipe 110 is used to supply heated hot water. The first pressure sensor 111 is disposed in the hot water pipe 110, and is configured to detect a water pressure of the hot water pipe 110 to obtain a first water pressure value. The first normal temperature water pipe 120 is used to supply normal temperature water. The second pressure sensor 121 is disposed in the first normal temperature water pipe 120, and is configured to detect a water pressure of the first normal temperature water pipe 120 to obtain a second water pressure value.
The water outlet device 200 is connected to the hot water pipe 110 and the first normal temperature water pipe 120, respectively, and is used for supplying water from the hot water pipe 110 and the first normal temperature water pipe 120 to the outside.
The water pressure adjusting part includes a first throttle valve 112 provided in the hot water pipe 110 and a second throttle valve 122 provided in the first normal temperature water pipe 120, and is configured to adjust an opening degree of the first throttle valve 112 and/or the second throttle valve 122 according to the first water pressure value and the second water pressure value such that the first water pressure value and the second water pressure value are balanced.
In the present embodiment, the specific manner of supplying hot water through the hot water pipe 110 is not limited, and may be selected according to the requirement. As a specific example, as shown in fig. 1, the hot water pipe 110 is communicated with the water outlet of the water heater 300 to obtain hot water. It will be apparent that this is merely exemplary and not exclusive. For example, the wall of the hot water pipe 110 or a heating member may be provided in the hot water pipe 110, and the heating member is used to heat the use water in the hot water pipe 110.
In the present embodiment, the type of the first pressure sensor 111 is not particularly limited, and may be selected as needed. The first pressure sensor 111 can sense the water pressure in the hot water pipe 110 and can convert the water pressure into a usable output electric signal according to a certain rule. For example, the first pressure sensor 111 may be a piezoresistive pressure sensor, a ceramic pressure sensor, a diffused silicon pressure sensor, or a sapphire pressure sensor, among others.
In the present embodiment, the normal temperature water refers to water that is not heated or cooled, that is, the normal temperature water refers to water in a natural environment state, that is, the normal temperature water refers to water in an environment state where the water supply system 10 is located.
In the present embodiment, the type of the second pressure sensor 121 is not particularly limited and may be selected as needed. The second pressure sensor 121 can sense the water pressure in the first normal temperature water pipe 120, and can convert the water pressure into an electric signal which can be output according to a certain rule. For example, the second pressure sensor 121 may be a piezoresistive pressure sensor, a ceramic pressure sensor, a diffused silicon pressure sensor, a sapphire pressure sensor, or the like.
In this embodiment, the specific type of the water outlet device 200 is not limited, and can be selected according to the requirement. For example, the water outlet device 200 may be a shower head or a faucet.
In this embodiment, the specific structure of the first throttle valve 112 is not limited, and can be selected according to the requirement. The first throttle valve 112 can change the throttle cross-sectional area or the throttle length of the hot water pipe 110 at the first throttle valve 112 to control the water flow in the hot water pipe 110. For example, the first throttle valve 112 may be a needle-type throttle valve.
In this embodiment, the specific structure of the second throttle valve 122 is not limited, and can be selected according to the requirement. The second throttle valve 122 can change the throttle cross-sectional area or the throttle length of the first constant temperature water pipe 120 at the second throttle valve 122 to control the water flow in the first constant temperature water pipe 120. For example, the second throttle valve 122 may be a needle-type throttle valve.
In this embodiment, when the first water pressure value and the second water pressure value are balanced, the magnitude relationship between the first water pressure value and the second water pressure value is not particularly limited, and may be selected as needed. For example, the first water pressure value and the second water pressure value are balanced, meaning that the first water pressure value and the second water pressure value are approximately equal or equal. The balance of the first water pressure value and the second water pressure value means that the proportion of the first water pressure value and the second water pressure value is stabilized at 1-2 times. The ratio of the first water pressure value to the second water pressure value is stabilized in a relationship of 0.5 to 1 time.
Therefore, the first pressure sensor 111 and the second pressure sensor 121 can detect the water pressure of the hot water pipe 110 and the first normal temperature water pipe 120 in real time. The water pressure adjusting part can adjust the opening degree of the first throttle valve 112 and/or the second throttle valve 122 according to the first water pressure value and the second water pressure value so that the first water pressure value and the second water pressure value are balanced. This enables the water pressure in the hot water pipe 110 and the first constant temperature water pipe 120 to be maintained within the set value in real time, so as to ensure that the temperature and the flow of the water flowing out of the water outlet device 200 are stable, and improve the user experience.
In other embodiments, the first pressure sensor 111 is located between the water outlet device 200 and the first throttle valve 112; the second pressure sensor 121 is located between the water outlet device 200 and the second throttle valve 122.
As shown in fig. 1, the first pressure sensor 111 is located between the water outlet device 200 and the first throttle valve 112, that is, the first pressure sensor 111 is located downstream of the first throttle valve 112 and upstream of the water outlet device 200, that is, the first throttle valve 112, the first pressure sensor 111 and the water outlet device 200 are sequentially arranged in the flow direction of the hot water. This allows the first pressure sensor 111 to accurately measure the water pressure downstream of the hot water pipe 110, that is, it allows the first pressure sensor 111 to accurately measure the water pressure at the position where the hot water pipe 110 is close to the water outlet means 200, that is, it allows the first pressure sensor 111 to accurately measure the water pressure at the position where the hot water pipe 110 is connected to the water outlet means 200. This can ensure that the temperature of the water and the water flow of the service water flowing out of the water outlet device 200 are stable, and improve the user experience.
As shown in fig. 1, the second pressure sensor 121 is located between the water outlet device 200 and the second throttle valve 122, that is, the second pressure sensor 121 is located downstream of the second throttle valve 122 and upstream of the water outlet device 200, that is, the second throttle valve 122, the second pressure sensor 121 and the water outlet device 200 are sequentially arranged along the flow direction of the normal temperature water. This enables the second pressure sensor 121 to accurately measure the water pressure downstream of the first constant temperature water pipe 120, that is, this enables the second pressure sensor 121 to accurately measure the water pressure at the position of the first constant temperature water pipe 120 close to the water outlet apparatus 200, that is, this enables the second pressure sensor 121 to accurately measure the water pressure at the position of the connection of the first constant temperature water pipe 120 and the water outlet apparatus 200. This can ensure that the temperature of the water and the flow of the water from the water outlet device 200 are stable, improving the user experience.
In some other embodiments, the water pressure adjusting part is configured to adjust the opening degree of the first throttle valve 112 and/or the second throttle valve 122 according to the first water pressure value and the second water pressure value when the flow rate of the hot water in the hot water pipe 110 is detected, so that the first water pressure value and the second water pressure value are balanced.
In this embodiment, the specific manner of detecting the hot water flow in the hot water pipe 110 is not limited, and may be selected according to the requirement. For example, a flow meter is provided in the hot water pipe 110, and the flow meter is used to detect the flow of water in the hot water pipe 110. When the flow rate of water in the hot water pipe 110 is detected, it is proved that the user wants the water outlet device 200 to simultaneously flow out the hot water and the normal temperature water, that is, the water outlet device 200 flows out the mixed water of the hot water and the normal temperature water. The water pressure adjusting part adjusts the opening degree of the first throttle valve 112 and/or the second throttle valve 122 in accordance with the first water pressure value and the second water pressure value in such a case that the first water pressure value and the second water pressure value are balanced. This makes the control of the water supply system 10 simple and ensures the water temperature and pressure of the water outlet device 200 to be stable.
In some other embodiments, the first throttle valve 112 is configured to control the hot water flow in the hot water pipe 110 to increase until the first water pressure value is equal to the second water pressure value when the first water pressure value is less than the second water pressure value.
This makes the water pressure of hot-water line 110 department and the water pressure of first normal atmospheric temperature pipe department equal to guarantee that the temperature of the water of using and rivers are stable that water installation 200 flows out, improve the user and use experience.
In some other embodiments, the first throttle valve 112 is configured to control the flow of hot water in the hot water pipe 110 to decrease when the first water pressure value is greater than the second water pressure value until the first water pressure value is equal to the second water pressure value.
This makes the water pressure of hot-water line 110 department and the water pressure of first normal atmospheric temperature pipe department equal to guarantee that the temperature of the water of using and rivers are stable that water installation 200 flows out, improve the user and use experience.
In some other embodiments, the second throttle valve 122 is configured to control the flow rate of the normal-temperature water in the first normal-temperature water pipe 120 to increase until the second water pressure value is equal to the first water pressure value when the first water pressure value is greater than the second water pressure value. This makes the water pressure at hot water pipe 110 and the water pressure at first normal atmospheric temperature pipe equal to guarantee that the temperature of the service water and rivers that go out of water installation 200 are stable, improve user's use and experience.
In some other embodiments, the second throttle valve 122 is configured to control the flow rate of the normal-temperature water in the first normal-temperature water pipe 120 to decrease until the second water pressure value is equal to the first water pressure value when the first water pressure value is less than the second water pressure value. This makes the water pressure at hot water pipe 110 and the water pressure at first normal atmospheric temperature pipe equal to guarantee that the temperature of the service water and rivers that go out of water installation 200 are stable, improve user's use and experience.
In other embodiments, the water supply system 10 further comprises a water heater 300, wherein a water outlet of the water heater 300 is communicated with the hot water pipe 110 for providing hot water to the hot water pipe 110.
In the present embodiment, the type of the water heater 300 is not limited and may be selected as desired. For example, the water heater 300 may be a gas water heater, an electric water heater, or a gas and electric integrated water heater. As a specific example, as shown in FIG. 1, the water heater 300 is an electric water heater. The hot water pipe 110 is communicated with the outlet of the water heater 300 to take hot water from the water heater 300, which makes the hot water of the water supply system 10 sufficient and the water temperature relatively stable.
In other embodiments, the water heater 300 includes a water tank 310. The water tank 310 serves to store hot water, and is communicated with the hot water pipe 110, for supplying hot water to the hot water pipe 110. The hot water pipe 110 is communicated with the water tank 310 of the water heater 300 to take hot water from the water tank 310, which makes the hot water of the water supply system 10 sufficient and the water temperature relatively stable.
In other embodiments, the water supply system 10 further includes a second normal temperature water pipe 400, and the second normal temperature water pipe 400 is communicated with the water inlet of the water heater 300 for providing normal temperature water to the water heater 300.
