Referring to fig. 3 to 5, the water heater in this embodiment includes a heating portion 11, a water inlet pipe 12 and a lock outlet pipe 13, the heating portion 11 is communicated with the water inlet pipe 12 and the water outlet pipe 13, cold water flows from the water inlet pipe 12 to the heating portion 11, and after being heated in the heating portion 11, the cold water flows out from the water outlet pipe 13 for a user to use, so as to heat water for the user.
The water inlet pipe 12 is provided with a water quantity adjusting part 14, the water quantity adjusting part 14 comprises a first flow passage 143 and a second flow passage 144, and at least one flow passage of the first flow passage 143 and the second flow passage 144 is provided with a water quantity adjusting device. The water inlet pipeline 12 adjusts the water inlet amount through the water amount adjusting part 14, so that when the water flow requirement of a user is high, the water flow can be adjusted through the water flow adjusting part, and particularly the adjusting device is adjusted.
It will be appreciated that the pipe diameters of the first flow channel 143 and the second flow channel 144 may be the same or different, specifically, in order to achieve steady flow under different water pressures, the pipe diameter of the first flow channel 143 may be set smaller to play a certain role in flow restriction, for example, the pipe diameter of the first pipe is smaller than that of the second flow channel 144, and the water volume adjusting device is disposed on the second flow channel 144, when the water volume demand of the user is smaller, the water volume adjusting device may be controlled to close the second flow channel 144, so that the second flow channel 144 is not conducted, cold water enters only through the first flow channel 143 with a small pipe diameter, the water volume is reduced, and based on the first flow channel 143 connected with the flow restriction, the water flow volume is smaller. When the water demand of the user is large, the water quantity adjusting device opens the second flow passage 144, and cold water enters through the first flow passage 143 and the second flow passage 144, so that the water flow rate is large.
Alternatively, referring to fig. 4 and 5, the water volume adjusting devices are disposed on the first flow channel 143 and the second flow channel 144, wherein the water volume adjusting device disposed on the first flow channel 143 is a throttle valve 141; the water amount adjusting means located on the second flow passage 144 is the shut-off valve 142. Thus, when the user has less water demand, the water quantity adjusting device closes the flow of the second flow passage 144, cold water can only enter from the first flow passage 143, the water quantity is reduced, and the water flow is smaller based on the throttling of the first flow passage 143. When the water demand of the user is large, the water quantity regulating device opens the flow of the second flow passage 144, and cold water enters through the first flow passage 143 and the second flow passage 144, so that the water flow is large.

The water consumption mode in this embodiment includes at least one of a comfort mode and an energy saving mode, and the target water consumption corresponding to the comfort mode is larger than the target water consumption in the energy saving mode. The application scenes corresponding to the comfort mode include, but are not limited to, the following: such as shower scenes, bath scenes, and surge scenes. The application scenarios corresponding to the energy saving mode include, but are not limited to, the following: such as ECO scenes (Ecology Conservation Optimization, ECO-energy optimization), hand wash scenes, kitchen scenes, etc. When the scenes such as shower and bathing are performed, the larger the water quantity output by the water heater is, the more comfortable the user is, the use effect of the water heater can be improved, and when the user washes hands, kitchens and dishes, the water quantity demand of the user is not large, the smaller the water quantity output by the water heater is, the more energy sources such as water, electricity and gas are saved, based on the water quantity demand, the water heater is provided with a comfortable mode and an energy-saving mode, the water flow is large in the comfortable mode, and the water flow is small in the energy-saving mode.
In this embodiment, the water usage mode switching instruction may be triggered when the operation is performed based on a control panel provided on the water heater, or may be triggered when the operation is performed based on a remote controller connected to the water heater, for example, when the water usage mode switching operation is detected when the user triggers the water usage mode switching operation based on the control panel of the water heater, or when the water usage mode selection operation sent by the user based on the remote controller is received, the detection of the water usage mode switching operation is determined. Or the water consumption mode can be automatically triggered in the use process of a user, for example, a processor of the water heater intelligently learns the water consumption mode corresponding to each water consumption position, for example, the water consumption mode corresponding to a kitchen is an energy-saving mode, the water consumption mode corresponding to a bathroom is comfortable, and the like, and when the opened position is different from the previous water consumption position based on the use of water by the user, a water consumption mode switching instruction is sent based on the current water consumption position, so that the water consumption mode switching instruction is detected by the water heater; or if the total power of the total gate of the household appliance is detected to be larger than the rated total power, and when the current water use mode is the comfort mode, automatically sending a water use mode switching instruction for switching to the energy-saving mode, so that the water heater detects the water use mode switching.
After detecting the water consumption mode switching instruction, the water heater acquires a target water consumption mode corresponding to the water consumption mode switching instruction, and acquires a target water quantity corresponding to the target water consumption mode based on a mapping relation between the water consumption mode and the target water inflow. For example, when the water consumption mode is the comfort mode, the target water consumption corresponding to the comfort mode is a large water consumption, and when the water consumption mode is the energy saving mode, the target water consumption corresponding to the energy saving mode is a small water consumption.

When the target water quantity is larger than the preset water quantity, correspondingly adjusting the water quantity adjusting device to increase the water inflow of the water inlet pipeline; and when the target water quantity is smaller than the preset water quantity, correspondingly adjusting the water quantity adjusting device to reduce the water inflow of the water inlet pipeline, so as to achieve the purpose of adjusting the water inflow according to the requirement of a water consumption mode.
Specifically, the water quantity adjusting device in this embodiment is disposed in the second flow channel, and the water quantity adjusting device is a stop valve, and the stop valve is used for stopping or switching on the second flow channel, so as to adjust the water inflow of the whole water quantity adjusting device. The step of controlling the water quantity adjusting device to adjust the water inflow of the water inlet pipeline according to the target water quantity comprises the following steps:
when the target water inflow is larger than the preset water inflow, namely the target water consumption is larger, the stop valve is controlled to be powered off so as to conduct the second flow passage, and at the moment, both the first flow passage and the second flow passage can be used for feeding water, so that the water inflow is increased, and the water outflow is increased;
when the target water inflow is smaller than the preset water inflow, namely the target water consumption is smaller, the stop valve is controlled to be electrified so as to close the second flow passage, at the moment, the first flow passage is filled with water, and the second flow passage is stopped from being filled with water, so that the water inflow is reduced, and the water outflow is reduced. And controlling the stop valve to be powered off until the user is powered off.
In this embodiment, the stop valve is in a normally open state, that is, the stop valve is turned on the second flow channel when the stop valve is turned off, and referring to fig. 3, the stop valve 142 includes a stop portion 1422 and a driving portion 1421 that drives the stop portion 1422 to move, the stop portion 1422 is mounted in the valve body and can move between an open position and a closed position of the second flow channel 144, when the stop valve 142 is turned on, the driving portion 1421 drives the stop portion 1422 to move to the closed position of the second flow channel 144 to close the second flow channel 144, and when the stop valve 142 is turned off, the stop portion 1422 moves to the open position of the second flow channel 144 under the action of water pressure.
In this embodiment, the stop valve 142 adopts the electromagnetic induction principle to control the driving portion 1421 to drive the stop portion 1422, specifically, when the driving portion 1421 is energized, the stop portion 1422 is moved in the direction of the stop portion 1422 by the electromagnetic adsorption force to press the stop portion 1422, and the force of the stop portion 1422 applied by the driving portion 1421 to the water pressure is opposite to the force applied by the water pressure and is greater than the water pressure, so that the stop portion 1422 stops at the closing position of the second flow channel 144 to close the second flow channel 144; when the driving portion 1421 is powered off, the driving portion 1421 is not subjected to an adsorption force, and moves away from the blocking portion 1422 to reset, when water enters the water quantity adjusting valve, the water applies pressure to the blocking portion 1422, the blocking portion 1422 moves towards the opening position of the second flow channel 144, the water can flow through the second flow channel 144, the blocking valve 142 is simple in structure and easy to implement, and compared with other adjusting devices, the cost is greatly saved.
The water heater of this embodiment is provided with multiple water consumption modes, and the water consumption that different water consumption modes correspond is different, combines to set up water yield adjustment portion and adjusts the inflow on the inlet tube, controls based on the water consumption mode of current operation water yield adjustment portion adjusts the inflow, realizes having different discharge under different modes, and intelligent control discharge satisfies the user and uses the requirement of scene to the water yield in the difference, and is energy-conserving comfortable again, improves the result of use of water heater. The water quantity adjusting part comprises a first flow channel and a second flow channel, the water quantity of the water quantity adjusting part is adjusted by arranging a water quantity adjusting device in at least one flow channel, and the water quantity adjusting part is simple in structure and low in production cost.
Further, when adjusting the water consumption, the firepower of the gas water heater is combined, so that the water temperature can be kept in the temperature range required by the user in different modes, and meanwhile, better energy-saving effect is achieved, for example, when the water consumption is large, the firepower is increased, so that the water temperature can reach the water temperature required by the user quickly, and when the water consumption is small, the gas waste is avoided, the firepower is reduced, and the like.
Referring specifically to fig. 6, fig. 6 is a second embodiment of a control method of a water heater according to the present invention, where the step of controlling the water amount adjusting device according to the target water amount to adjust the water inflow amount of the water inlet pipeline further includes:
step S40, obtaining a target water temperature and a water inlet temperature;
s50, determining a proportion value of a fuel gas proportion valve according to the target water temperature, the inflow water temperature and the target inflow amount;
and step S60, adjusting the fuel gas proportional valve according to the proportional value.
It will be appreciated that, with continued reference to fig. 3 to 5, the heating portion 11 in this embodiment includes a burner 111 and a heat exchanger 112, the burner 111 is located below the heat exchanger 112, the burner 111 is connected to a gas inlet, the heat exchanger 112 is connected to the water inlet pipe 12, water enters the heat exchanger 112 from the water inlet of the water inlet pipe 12 after the water amount is adjusted by the water amount adjusting portion 14, the burner 111 heats the heat exchanger 112, and after the water in the heat exchanger 112 exchanges heat with the plate heat exchanger 112, the water is discharged from the water outlet pipe 13, so as to complete water heating and use. The burner comprises a fuel gas proportional valve, wherein the fuel gas proportional valve is used for adjusting the air inlet proportion of fuel gas so as to realize adjustment of firepower.
In this embodiment, the target water temperature is a water temperature required by a user, and the water inlet temperature is a water inlet temperature at a water inlet of the current water heater. The fuel gas proportional valve is determined according to the target water temperature, the water inlet water temperature and the target water inlet amount, so that the proportional value of the fuel gas proportional valve is determined by combining the corresponding target water inlet amount in the current target mode, and then the proportional value of the fuel gas proportional valve is adjusted, so that the combination adjustment of the water inlet amount and the fuel gas proportion is realized, the energy is saved, the water quantity and the temperature requirements of a user on water are met, and the use effect of the water heater is better.
It can be understood that the target water temperature can be set by a user through a control panel or a remote controller of the water heater, and in order to achieve finer and more intelligent heating effect, the target water temperature can be automatically obtained, for example, the target water temperature can be in one-to-one correspondence with a target water usage mode, so that after the target water usage mode is determined, the target water temperature can be determined according to the target water usage mode, or the target water temperature can be in one-to-one correspondence with the user, for example, a user information identification device, such as a fingerprint collector or a camera, is arranged on the water heater, so that the target water temperature can be determined according to the water usage user; or, the target water temperature can also be in one-to-one correspondence with the water consumption mode and the users, and the water temperatures required by different users are different as in the water consumption mode, and after the target water consumption mode is determined, the corresponding target water temperature in the target water consumption mode is determined according to the users. Or the target water temperature corresponds to the water consumption position one by one, for example, the water temperature corresponding to the kitchen water is lower, or the water temperature of the hand washing water is relatively higher, and the like, so that the target water temperature can be determined according to the water consumption position. Or after determining the target water usage pattern, determining the water usage temperature in that pattern based on the water usage position.
Further, referring to fig. 7, if the target water consumption mode is a comfort mode, that is, the target water intake amount is a large water intake amount, the water heater is prevented from being damaged by overload operation for a long time in order to prolong the service life of the water heater. In this way, a third embodiment is provided based on the above second embodiment, in this embodiment, before the step of determining the ratio value of the fuel gas proportional valve according to the target water temperature, the intake water temperature, and the target water inflow, the step of obtaining the target water temperature and the intake water temperature further includes:
step S70, if the target water inflow is larger than the preset water inflow, calculating a target heating load according to the target water temperature, the water inflow temperature and the target water inflow;
and S80, detecting that the target heating load is larger than the rated load, controlling the stop valve to be electrified so as to close the second flow passage, and updating the target water inflow with the water inflow after closing the second flow passage.
That is, when the target water inflow corresponding to the target water use mode is in the large water use mode, if the ratio value of the fuel gas proportional valve is directly calculated according to the target water inflow, the target temperature and the water inflow temperature, the water heater may be in overload operation, especially in winter, the water inflow temperature is lower. Therefore, when the target water inflow is determined to be greater than the factor and the water inflow, the embodiment calculates the target heating load according to the target water temperature, the water inflow temperature and the target water inflow, specifically calculates the required heating load according to the energy required for reaching the target water temperature from the current water inflow temperature, if the target heating load is greater than the rated load, the overload operation of the water heater is indicated, and even the overload operation cannot reach the target water temperature, so that the cut-off valve is controlled to be electrified to close the second flow passage, and the water inflow is reduced, thereby reducing the heating load. If the target heating load is smaller than or equal to the rated load, the water heater is not in overload operation, and can be kept to operate in the current large water mode, namely the stop valve is controlled to be kept in a power-off state.
After the second flow channel is closed, the target water inflow is updated by adopting the water inflow after the second flow channel is closed, so that the water heater determines the proportional value of the fuel gas proportional valve according to the target water temperature, the water inflow temperature and the updated target water inflow, and further more accurate adjustment of the fuel gas proportional valve is realized.
It can be understood that if the target heating load is detected to be greater than the rated load, the stop valve is controlled to be electrified so as to keep the stop valve in an electrified state after the second flow passage is closed, until a user closes the water heater, or a mode switching instruction is detected again, and then the stop valve is adjusted according to a target water use mode corresponding to the mode switching instruction.
Or in a fourth embodiment, referring to fig. 8, based on the third embodiment, after the step of controlling the shut-off valve to be energized to close the second flow passage and updating the target water intake amount with the water intake amount after closing the second flow passage when the target heating load is greater than the rated load, the present embodiment further includes:
and step S90, when the target heating load is smaller than the rated load, controlling the stop valve to be powered off so as to open the second flow passage, and updating the target water inflow with the water inflow after the second flow passage is opened.
