In some embodiments of the present description, the controller includes at least one of: a remote controller; an associated application installed in the user terminal; a main controller arranged in the water heating device; a switching device disposed adjacent to the water point; a wall switch.
In this embodiment, the controller may be implemented in various ways. In one embodiment, the controller may be configured as a remote control on which at least one button may be provided for controlling the on or off of a plurality of valves in the hot water system. The remote control may be communicatively coupled to a plurality of valves.
In one embodiment, the controller may be an associated application installed in the user terminal.

For example, the controller may be located near the faucet at the point of use, may be provided as a button or other form of switching device. The switching devices may be communicatively connected to the corresponding valves to control the turning on or off of the solenoid valves.
In one embodiment, the controller may be configured as a wall switch. For example, the controller may be provided in the wall switch near the water branch or near the water heating device.
The embodiments of the controller described above are illustrative only and this description is not intended to be limiting.
In some embodiments of the present disclosure, a wireless communicator may be disposed on the solenoid valve, and the solenoid valve may be communicatively coupled to the controller via the wireless communicator. Through setting up wireless communicator, can make solenoid valve and controller communication connection, the user of being convenient for control solenoid valve's switching on or off as required.
In some embodiments of the present description, a temperature sensor may be provided on the solenoid valve. The temperature sensor may be communicatively coupled to the controller. The controller may be configured to control the solenoid valve to be turned off when the temperature data detected by the temperature sensor indicates that the water temperature of the cold water pipe or the hot water pipe of the water branch where the solenoid valve is located reaches a first preset temperature.
In this embodiment, a temperature sensor may be disposed on the solenoid valve, and the temperature sensor may be in communication connection with the controller. In one embodiment, a temperature sensor may be provided at a side of the solenoid valve near the cold water pipe for detecting the water temperature of the cold water pipe of the water branch. The temperature sensor may send the detected temperature data to the controller.
The controller can determine whether the water temperature of the cold water pipe of the water branch where the electromagnetic valve is located reaches a first preset temperature based on the detected temperature data, if so, the electromagnetic valve is controlled to be turned off, and the cycle is ended. The first preset temperature may be a set temperature of the water heating device by a user, or may be lower than the set temperature. For example, if the set temperature is 40 degrees celsius, the first preset temperature may be any temperature value within 35-40 degrees celsius. Under the condition that the temperature of the cold water pipe reaches the first preset temperature, the zero cold water function of the water consumption point is achieved, and the water circulation can be stopped, so that the energy consumption is saved.
In another embodiment, a temperature sensor may be provided at a side of the solenoid valve near the hot water pipe for detecting the temperature of the hot water pipe of the water branch. The temperature sensor may send the detected temperature data to the controller. Under the condition that the electromagnetic valve is in a conducting state, as the hot water pipe and the cold water pipe are conducted to conduct water circulation, the temperature of the cold water pipe is similar to that of the hot water pipe, and therefore the controller can determine whether the water temperature of the hot water pipe of the water branch where the electromagnetic valve is located reaches a first preset temperature or not based on the detected temperature data, if so, the electromagnetic valve is controlled to be turned off, and circulation is ended.
It will be appreciated that the temperature sensor in the embodiments of the present disclosure may also be located elsewhere, for example, in the cold water pipe of the water branch near the water point.
In some embodiments of the present disclosure, the controller may be further configured to control the electromagnetic valve to be turned on when the temperature data detected by the temperature sensor indicates that the water temperature of the cold water pipe or the hot water pipe of the water branch where the electromagnetic valve is located is lower than a second preset temperature, where the second preset temperature is lower than the first preset temperature.
In this embodiment, the controller may automatically control the water usage branch or the water usage point satisfying the condition to circulate, so as to realize the zero cold water function. Specifically, the temperature sensor may send the detected temperature data to the controller.
And the controller controls the electromagnetic valve to be conducted under the condition that the temperature data indicate that the water temperature in the corresponding cold water pipe is lower than a second preset temperature. The second preset temperature is smaller than the first preset temperature. For example, the second preset temperature may be set to 25 ℃. Under the condition that the temperature of the cold water pipe is lower than a second preset temperature, the temperature in the cold water pipe of the water consumption point is lower and does not meet the zero cold water requirement, so that the corresponding electromagnetic valve can be controlled to be conducted so as to circulate, and the zero cold water function is realized.
And the controller controls the electromagnetic valve to be conducted under the condition that the temperature data detected by the temperature sensor indicates that the water temperature in the hot water pipe is lower than a second preset temperature. The second preset temperature is smaller than the first preset temperature, and the first preset temperature is smaller than or equal to the set temperature. Under the condition that the water temperature in the hot water pipe is lower than the second preset temperature, the fact that the water temperature in the hot water pipe is obviously lower than the preset temperature is indicated, and the water in the hot water pipe needs to be heated is indicated, so that the electromagnetic valve can be controlled to be conducted, the water in the hot water pipe and the cold water pipe circularly flow into a heat exchanger of the hot water device to be heated, and the water temperature in the hot water pipe reaches the first preset temperature until the temperature data detected by the temperature sensor indicates that the water temperature in the hot water pipe reaches the first preset temperature.
The automatic starting method in the embodiment can aim at the electromagnetic valve which is expected to be opened by a user, and does not automatically open the electromagnetic valve corresponding to the water consumption point of which the zero cold water function is not opened by the user.
In the above embodiment, for the valve corresponding to the water consumption point of the zero cold water function designated to be opened by the user, the controller may control the on/off of the electromagnetic valve according to the temperature data detected by the temperature sensor corresponding to the water consumption branch, so as to save energy consumption on the premise of realizing the zero cold water function.
In some embodiments of the present disclosure, the controller may further be configured to control the plurality of solenoid valves to be sequentially turned on when a control signal for controlling the plurality of solenoid valves to be turned on is received.
In this embodiment, in some application scenarios, the user may turn on the zero cold water function of the water point located in the different water usage branches, and need to turn on the solenoid valves set in the different water usage branches. Considering that the simultaneous opening of the solenoid valves located in different water branches may result in a longer circulation waiting time for each water point, the controller may control at least two solenoid valves to be sequentially turned on. For example, the user turns on the zero cold water function of the first water spot and the third water spot, at which time the first valve and the third valve need to be turned on. In this case, the controller may control the first valve to be turned on first until the water temperature of the first water-spot cold water pipe reaches a first preset temperature, control the first valve to be turned off, and control the third valve to be turned on until the water temperature of the third water-spot cold water pipe reaches the first preset temperature, and control the third valve to be turned off. The electromagnetic valves positioned in different water branches are controlled to be sequentially conducted at intervals, so that the circulation waiting time can be shortened, and the water consumption experience of users is improved.
Referring to fig. 3, as shown in fig. 3, in some embodiments of the present disclosure, the plurality of water usage branches may further include a third water branch 63. As shown in fig. 3, the first communication structure 40 and the second communication structure 50 may be four-way connectors. The third water branch 63 may comprise at least one water point. A valve is arranged between the cold water pipe and the hot water pipe of one or more water points of the third water branch. As shown in fig. 3, the third water branch 63 may include a fourth water usage point 633. A fourth valve 704 may be provided between the third cold water pipe 632 and the third hot water pipe 631 of the fourth water use point 633.
It will be appreciated that the water heating system according to the embodiments of the present disclosure may further include three or more water usage branches, where each water usage branch may include at least one water usage point.
In some embodiments of the present disclosure, the check valve is set to be in an on state when the pressure applied to the check valve is equal to or greater than a preset pressure value, and is set to be in an off state when the pressure applied to the check valve is less than the preset pressure value. The pressure here is the pressure difference across the non-return valve. Under the condition that the pressure is greater than or equal to a preset pressure value, the one-way valve is in a conducting state, and under the condition that the pressure is less than the preset pressure value, the one-way valve is in a cutting-off state.
In some embodiments of the present disclosure, the preset pressure value may be greater than a pressure to which the check valve is subjected when the solenoid valve is in a conductive state; the preset pressure value is smaller than the pressure applied to the one-way valve when the electromagnetic valve is in a closing state and the water heating device is in a starting state.
Specifically, since the preset pressure value is greater than the pressure to which the check valve is subjected when the solenoid valve is in the on state, the pressure to which the check valve is subjected is less than the preset pressure value when the solenoid valve is in the on state, and the check valve is in the off state. Because the preset pressure value is smaller than the pressure born by the one-way valve when the electromagnetic valve is in the off state and the water heating device is in the on state, the pressure born by the one-way valve is larger than the preset pressure value when the electromagnetic valve is in the off state and the water heating device is in the on state, and therefore the one-way valve can be conducted, water circulation of a corresponding water branch is achieved, and the zero cold water function is achieved.
In some embodiments of the present disclosure, the check valve is in an off state when the controller controls the solenoid valve to conduct. Because the check valve is switched on and off according to the pressure difference, under the condition that the controller controls the electromagnetic valve to be switched on, the pressure difference is possibly insufficient to enable the check valve to be switched on because the on circulation is used for relieving the pressure of the water in the hot water pipe. Thus, in the case where the controller controls the solenoid valve to be turned on, the check valve may be in an off state.
In some embodiments of the present disclosure, the one-way valve is in an on state when the controller controls each of the at least one solenoid valve to be off. Under the condition that the controller controls all the electromagnetic valves to be in a closing state, the one-way valve can be in a conducting state due to pressure difference.
In some embodiments of the present description, the solenoid valve may be an opening-adjustable valve, and the controller may be further configured to control the opening of the solenoid valve. In this embodiment, the opening degree of the solenoid valve may be adjusted so that the flow rate of the circulation may be adjusted. Accordingly, the controller may control the opening size of the solenoid valve. The opening of the electromagnetic valve is set to be adjustable, so that a user can adjust the opening of the electromagnetic valve according to the needs, and then the flow of each cycle is controlled, and the cycle waiting time of each water branch or each water point is controlled.
In some embodiments of the present disclosure, the one-way valve is in a conductive state when the opening of the solenoid valve is within a preset opening range.
In this embodiment, since the opening of the solenoid valve is adjustable, the check valve is in the on state when the opening of the solenoid valve controlled by the controller is within the preset opening range. For example, in the case where the opening degree of the solenoid valve is smaller than the preset opening degree, the check valve may be in the on state. In this embodiment, through the aperture of control solenoid valve, can make solenoid valve and check valve switch on simultaneously, can satisfy user's diversified demand.
In some embodiments of the present disclosure, in a case where the plurality of solenoid valves are in a conductive state, the controller is further configured to control an opening degree of each of the plurality of solenoid valves according to a preset rule.
When the plurality of solenoid valves are in the on state, the controller may control the opening degree of each of the plurality of solenoid valves according to a preset rule. The preset rules herein may be set according to the user's water usage habits. For example, in the case where both the first solenoid valve and the second solenoid valve are in the on state, the controller may determine the opening degrees of the first solenoid valve and the second solenoid valve in different time periods according to the user's water usage habit. For example, if the current time period is from eight to ten pm, the user will generally use the toilet corresponding to the second electromagnetic valve to wash in the current time period, so that in the current time period, the opening of the second electromagnetic valve can be controlled to be the largest, and the opening of the first electromagnetic valve can be controlled to be the smallest or closed, so as to meet the water requirement of the user. For example, the current time period is six to eight am points, and the user usually uses the toilet corresponding to the first electromagnetic valve to wash in the current time period, so that the opening of the first electromagnetic valve is controlled to be maximum, and the opening of the second electromagnetic valve is controlled to be minimum or closed in the current time period, so as to meet the water use requirement of the user.
In this specification, each embodiment is described in a progressive manner, and identical and similar parts of each embodiment are all referred to each other, and each embodiment mainly describes differences from other embodiments. Specific reference may be made to the foregoing description of related embodiments of the related process, which is not described herein in detail.
