Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.

The water supply system 1000 of the embodiment of the invention generally includes a heating device 200 and a water outlet device 300, wherein the heating device 200 may be a gas water heater, a wall-hanging stove, a phase-change water heater, an electric water heater, etc., and the water outlet device 300 may be a shower head, a faucet, etc.

A hot water path 400 and a cold water path 500 are generally provided between the heating apparatus 200 and the water outlet apparatus 300, wherein the hot water path 400 is connected to a hot water port 202 of the heating apparatus, and the cold water path 500 is connected to a cold water port 201 of the heating apparatus.

As is well known to those skilled in the art, a return water circuit 600 is generally provided between the hot water circuit 400 and the cold water circuit 500, so that residual cold water in the circuits is sent back to the heating apparatus 200 to be heated, thereby enabling the water supply system 1000 to have a zero cold water function. However, in the case where the water supply system 1000 is additionally provided with a pressurization function or cold water is used alone, a part of the hot water in the hot water path 400 is easily diverted to the cold water path 500, resulting in a waste of the amount of the hot water. Based on the above facts, the present invention provides a water path adjusting assembly 100, and the water path adjusting assembly 100 can ensure that the water supply system 1000 obtains a zero-cold water function, and can prevent hot water from streaming to the cold water path 500, thereby improving the user experience and saving energy consumption.

A waterway regulation assembly 100 according to an embodiment of the present invention will be described with reference to fig. 1 to 9.

As shown in fig. 1 to 9, the waterway regulation assembly 100 includes: a valve body 10, a valve element 20 and a temperature control element 30.

The valve body 10 has a hot water pipe 11, a cold water pipe 12, and a communication pipe 13 connecting the hot water pipe 11 and the cold water pipe 12. For example, the valve body 10 has a substantially U-shaped or H-shaped pipe structure, in which the hot water pipe 11 is connected to the hot water path 400 and the cold water pipe 12 is connected to the cold water pipe 12 in the pipe connection of the water supply system 1000. Here, "connected" may be directly connected or indirectly connected.

In addition, the hot water pipe 11, the cold water pipe 12 and the communicating pipe 13 may be integrally formed parts, so as to facilitate the processing and forming of the pipeline structure, wherein the valve body 10 may be a copper casting or a stainless steel part.

The valve element 20 is provided in the communication pipe 13, and the valve element 20 unidirectionally communicates the water path from the hot water pipe 11 to the cold water pipe 12 when the water pressure in the hot water pipe 11 is higher than the water pressure in the cold water pipe 12. For example, at the beginning of the use of the water supply system 1000, the water pump is started, the water in the hot water path 400 is driven by the water pump to flow back to the cold water path 500 through the path adjusting assembly 100, and at this time, the water outlet device 300 is in the closed state, and the valve element 20 is in a position for conducting the hot water pipe 11 and the cold water pipe 12.

The temperature control element 30 is provided in the communication pipe 13, and when the water path from the hot water pipe 11 to the cold water pipe 12 is conducted and the water temperature in the communication pipe 13 reaches a predetermined value, the temperature control element 30 blocks the communication pipe 13. In other words, in the case that the temperature of the water in the hot water path 400 reaches the predetermined value, that is, the hot water path 400 has no residual water, if the water pressure in the hot water pipe 11 is still greater than the water pressure in the cold water pipe 12, the temperature control element 30 may block the water flow from the hot water pipe 11 to the cold water pipe 12, and thus, the cross flow between the hot water pipe 11 and the cold water pipe 12 may be avoided. It should be noted that the "predetermined value" refers to a value at which the temperature control element 30 completely cuts off the water temperature of the communication pipe 13, and when the water temperature in the communication pipe 13 is between the predetermined value and the normal temperature water temperature, the temperature control element 30 may shut off the communication pipe 13, that is, when the water temperature in the communication pipe 13 has not reached the predetermined value, the water flow in the communication pipe 13 may be reduced to a certain extent, and the flow rate of the hot water flowing to the cold water pipe 12 may be reduced.

Because the communicating pipe 13 is provided with the valve element 20 and the temperature control element 30, the waterway regulation assembly 100 of the embodiment of the present invention has a plurality of use states, and in case that the water supply system 1000 is stopped (i.e. in case that the water supply system 1000 does not supply hot water or cold water to the outside), the valve element 20 closes the inlet of the communicating pipe 13, as shown in fig. 1, 4 and 7; at the beginning of using hot water from the water supply system 1000, the valve element 20 opens the inlet of the communication pipe 13, the temperature control element 30 does not cut off the communication pipe 13, and the water in the hot water pipe 11 can flow back to the cold water pipe 12, as shown in fig. 2, 5 and 8; in the case where the water supply system 1000 uses hot water externally for a certain period of time, at which the temperature of water in the communication pipe 13 has reached the predetermined value, the valve element 20 opens the inlet of the communication pipe 13, and the temperature control element 30 shuts off the communication pipe 13, as shown in fig. 3, 6, and 9.

In short, according to the waterway regulation assembly 100 of the embodiment of the present invention, the on/off of the connection pipe 13 is controlled by providing the valve element 20 and the temperature control element 30 in the connection pipe 13, so that even if the pressurization function is used in the water supply system 1000, the cross flow between the hot water channel and the cold water channel can be prevented, the loss of hot water amount is reduced, and the loss of energy consumption is reduced.

In some embodiments of the present invention, the cold water pipe 12 is provided with a mounting interface 121 disposed opposite to the communication pipe 13, the mounting interface 121 is provided with an end cap 14 for closing the mounting interface 121, and the valve element 20 and the temperature control element 30 are assembled into the communication pipe 13 through the mounting interface 121, wherein the valve element 20 is disposed adjacent to the hot water pipe 11. Namely, the installation interface 121 penetrates through the wall thickness of the cold water pipe 12, so that the valve element 20 and the temperature control element 30 are conveniently arranged in the communication pipe 13, and the on-off of the communication pipe 13 is effectively controlled. By arranging the valve element 20 and the temperature control element 30 in the communication pipe 13, the residual water is returned, and the cross flow between the hot water path and the cold water path is prevented.

In an alternative embodiment, as shown in FIGS. 1-9, the end cap 14 defines a first channel 141 and a second channel 142 in communication with each other. The first water channel 141 is communicated with the communication pipe 13, and the second water channel 142 is communicated with the cold water pipe 12. That is, the end cap 14 not only can prevent the water in the valve body 10 from leaking from the installation interface 121, but also can form a water channel for communicating the cold water pipe 12 and the communicating pipe 13, thereby ensuring that the water channel is smooth.

In some alternative examples, as shown in fig. 1-3, the end cap 14 includes: an insert 143 and a closure 144. The insertion portion 143 is inserted into an outlet of the communication pipe 13, the insertion portion 143 forms a first water passage 141, and the temperature control member 30 opens or closes an inlet of the first water passage 141. In this embodiment, the valve element 20 is provided at the inlet of the communication pipe 13, and the opening degree of the inlet of the communication pipe 13 is regulated by the valve element 20. The larger the pressure difference between the hot water pipe 11 and the cold water pipe 12 is, the larger the opening degree of the inlet of the communication pipe 13 is, and conversely, the smaller the opening degree of the inlet of the communication pipe 13 is. When there is a pressure difference between the hot water pipe 11 and the cold water pipe 12 and the temperature of the water in the communication pipe 13 is equal to or higher than a predetermined value, the opening degree of the outlet of the communication pipe 13 is adjusted by the temperature control element 30.

Further alternatively, the temperature control element 30 comprises at least a telescopic rod 31, and in case the water temperature in the communicating pipe 13 reaches a predetermined value, the telescopic rod 31 closes the inlet of the first water channel 141. In this embodiment, in the case where the communication pipe 13 is conducted by the valve element 20 and the water temperature in the communication pipe 13 reaches a predetermined value, the telescopic rod 31 closes the inlet of the first water passage 141, that is, the valve element 20 and the temperature control element 30 control the opening and closing of the inlet and the outlet of the communication pipe 13, respectively. It should be noted that, when the cold water pipe 12 delivers cold water to the outside, a pressure difference is also generated between the hot water pipe 11 and the cold water pipe 12, and at this time, the telescopic rod 31 can also play a throttling role, so as to reduce the proportion of hot water mixed into the cold water pipe 12.

In other embodiments of the present invention, the temperature controlled element 30 exerts an abutting force on the valve element 20 so that the valve element 20 closes the inlet of the communication pipe 13. In this embodiment, both the temperature-controlled element 30 and the valve element 20 can control the opening degree of the inlet of the communication pipe 13 in common. The waterway regulation assembly 100 at least comprises two using states, when the water pressure in the hot water pipe 11 is higher than the water pressure in the cold water pipe 12 and the water temperature in the communicating pipe 13 is lower than a preset value, the valve element 20 conducts the waterway from the hot water pipe 11 to the cold water pipe 12, at this time, the temperature control element 30 does not exert acting force on the valve element 20, and the valve element 20 conducts the communicating pipe 13; in the case where the water pressure in the hot water pipe 11 is higher than the water pressure in the cold water pipe 12 and the water temperature in the communication pipe 13 is a predetermined value, the temperature control element 30 exerts a biasing force on the valve element 20, forcing the valve element 20 to disconnect the communication pipe 13.

Alternatively, as shown in fig. 4-6, the end cap 14 includes: the temperature control element 30 is disposed in the end cap 14, the temperature control element 30 at least includes a telescopic rod 31, one end of the telescopic rod 31 is connected to the abutting portion 145, and the other end of the temperature control element 30 is disposed opposite to the valve element 20. In this way, when the water pressure in the hot water pipe 11 is higher than the water pressure in the cold water pipe 12 and the water temperature in the communication pipe 13 is a predetermined value, the extendable rod 31 abuts on the valve element 20, so that the valve element 20 closes the inlet of the communication pipe 13.

In an alternative embodiment, as shown in fig. 7-9, the valve body 10 further comprises a valve housing 15, both ends of the valve housing 15 are open, an abutting plate 151 is provided at one end of the valve housing 15 adjacent to the cold water pipe 12, and the temperature control element 30 is integrally provided on the valve element 20. In this embodiment, the valve element 20 and the temperature control element 30 may be assembled together in the valve housing 15 and then assembled as a unit from the mounting interface 121 into the valve body 10. After the end cap 14 is placed in the mounting port 121, the end cap 14 abuts against the valve housing 15, so that the valve housing 15 and the end cap 14 are firmly fixed in the communication pipe 13.

Wherein, the temperature control element 30 at least comprises: the extendable rod 31 has one end of the extendable rod 31 connected to the valve element 20 and the other end of the extendable rod 31 disposed opposite the abutment plate 151, and when the temperature of the water in the communication pipe 13 reaches a predetermined value, the extendable rod 31 abuts against the abutment plate 151. In this embodiment, the extension rod 31 is usually connected to the valve element 20, and the extension rod 31 and the valve element 20 are integrated in the valve housing 15 and can move synchronously with each other. In the case where the water temperature in the communication pipe 13 has reached the predetermined value, the valve element 20 cannot be timely returned to close the inlet of the communication pipe 13, and the expansion link 31 may abut against the abutting plate 151 due to the water temperature, and the valve element 20 may disconnect the communication pipe 13.

In an alternative embodiment, as shown in fig. 1-9, the valve element 20 includes at least: the valve plug 21, the push rod 22 and the elastic piece 23, the elastic piece 23 is sleeved on the push rod 22, under the condition that the water pressure in the hot water pipe 11 is less than or equal to the water pressure in the cold water pipe 12, the elastic piece 23 exerts thrust on the push rod 22 to enable the valve plug 21 to reset, and therefore the inlet of the communicating pipe 13 is sealed. The valve plug 21 and the pushrod 22 may be a single component, as shown in fig. 1-6, or the valve plug 21 and the pushrod 22 may be two separate components connected to each other, as shown in fig. 7-9. The principle of operation of the valve element 20 is well known to those skilled in the art and will not be described in detail herein.

Alternatively, at least a portion of the telescopic rod 31 is made of a phase change material, and the length of the telescopic rod 31 is lengthened or shortened as the temperature of the water in the communicating pipe 13 changes. The phase change material has a property of absorbing heat and expanding and releasing heat and shortening, and as the temperature of water in the communication pipe 13 increases, the expansion link 31 gradually absorbs heat and extends, so that, in a case where the valve element 20 opens the communication pipe 13 and the temperature of the water reaches a predetermined value, the length of the expansion link 31 may be such that the inlet of the first water passage 141 is closed to cut off the communication pipe, or a biasing force is applied to the valve element 20, so that the valve element 20 opens the communication pipe 13. In case that the temperature of the water in the communication pipe 13 is gradually decreased, the expansion link 31 releases heat and its length is shortened to open the inlet of the first water passage 141, or the expansion link 31 is away from the valve element 20 such that the valve element 20 opens the communication pipe 13.

As shown in fig. 1 to 9, the telescopic rod 31 is provided with a return spring 32, so that after the water temperature of the communication pipe 13 is reduced, the return spring 32 can apply a restoring force to the telescopic rod 31, so that the telescopic rod 31 is restored as soon as possible.

At the beginning of the use of the water supply system 1000, the residual water of the hot water circuit 400 may flow back to the cold water circuit 500 through the water circuit adjusting assembly 100 and enter the heating apparatus 200 for heating through the cold water circuit 500. That is, the cold water path 500, the water path adjusting unit 100, the hot water path 400 and the heating apparatus 200 form a closed heating water path, and the connection pipe 13 of the water path adjusting unit 100 is disconnected after the temperature of the hot water path 400 reaches a predetermined value.
