Detailed Description
Preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention. For example, although the present embodiment describes the control method of the water heater in the present embodiment by taking the water heater with three stages of water storage cavities as an example, this is not a limitation to the application object of the control method of the water heater provided in the present embodiment, and it can be understood that a person skilled in the art can make adjustments to the application object of the control method of the water heater in the present embodiment as needed to adapt to specific application occasions.
In order to solve the above problems in the prior art, that is, to solve the problem that the existing water heater generally supplements hot water to the existing water heater by heating tap water, and the required hot water time is long, so that the hot water can not meet the requirement of a user on the urgent use of hot water, the present embodiment provides a control method of the water heater.
First, as shown in fig. 1, the water heater provided in this embodiment includes a hot water main unit 8 and a water tank, where a plurality of water storage cavities (such as a first water storage cavity 11, a second water storage cavity 12, and a third water storage cavity 13 in fig. 1) are arranged inside the water tank; the peripheral wall of each water storage cavity is provided with a heat insulation layer, and each water storage cavity is provided with a water inlet (shown as the position where the first water storage cavity 11 is connected with the first control valve 21 in the figure 1), a water outlet (shown as the position where the first water storage cavity 11 is connected with the second control valve 31 in the figure 1) and a water outlet (shown as the position where the first water storage cavity 11 is connected with the third control valve 41 in the figure 1); the water inlet of each water storage cavity is communicated with the water outlet of a hot water host machine 8 of the water heater through a water inlet pipe 2; the water outlet of each water storage cavity is communicated with the water inlet of the hot water main unit 8 through the water outlet pipe 3; the outlet of each water storage chamber is used for supplying domestic water through a drain pipe 4. It should be noted that, although the embodiment is described by taking the water heater with three water storage cavities as an example, the number of the water storage cavities in practical application is not limited to three, and may be other numbers, and such adjustment of the number of the water storage cavities does not limit the present invention, and all of them should fall within the protection scope of the present invention.
Illustratively, the hot water main unit 8 may be selected from any one of a solar hot water main unit 8, an air-source heat pump hot water main unit 8, and an electric hot water main unit 8. As shown in fig. 1, in the embodiment, the water tank is exemplified by being sequentially provided with a first water storage cavity 11, a second water storage cavity 12 and a third water storage cavity 13 from top to bottom, and each water tank is configured to be used for containing water with different temperatures, preferably, the water storage cavities can be configured in a manner that the water temperature is preset to gradually increase from top to bottom. Therefore, when the user uses hot water in the water storage cavity with higher water temperature and continues to use the hot water in the hot water cavity next time, the hot water with lower water temperature in the upper-stage water storage cavity can be directly supplemented into the water storage cavity with higher water temperature after being heated. Therefore, the heating time of hot water in the water storage cavity with higher water temperature is reduced, and the use experience of a user is improved.
The water outlet pipe 3 is connected with a water replenishing pipe 5 through a three-way valve 51, when water is required to be replenished, the water replenishing pipe 5 is communicated with a water inlet of the hot water main machine 8 through the three-way valve 51, and the water is heated by the hot water main machine 8 and then is injected into a water tank; or a water replenishing port connected with the water replenishing pipe 5 can be arranged on the water storage cavity, and water is directly replenished to the water tank through the water replenishing port. In order to provide power for the water flow between the hot water main unit 8 and the water tank, a water pump (not shown) may be disposed on the water outlet pipe 3 to suck the water replenishing pipe 5 connected to the water outlet pipe 3 or the water in the water tank into the hot water main unit 8, and form a water circulation between the hot water main unit 8 and the water tank.
In order to independently control the water inlet, the water outlet and the water discharge of each water storage cavity, the water inlet of the water tank of the embodiment is communicated with one end of the water inlet pipe 2 through the first control valve 21 which is connected with the water inlet of each water storage cavity; the water outlet of each water storage cavity is communicated with one end of a water outlet pipe 3 through a second control valve 31 which is connected with the water storage cavity; the water outlet of each water storage cavity is communicated with one end of the water discharge pipe 4 through a third control valve 41 which is respectively connected with the water storage cavities.
The first control valve 21, the second control valve 31 and the third control valve 41 in the water tank are preferably solenoid valves or electric valves, and the first control valve 21, the second control valve 31 and the third control valve 41 can be automatically controlled by a controller in the water heater. A temperature sensor 6 and a water level monitoring meter 7 are arranged in the water storage cavities to respectively monitor the water temperature and the water level in different water storage cavities in real time, so that a user can know the state of each water storage cavity or provide required data information for the automatic control of the water heater.
As a preferred implementation of the above water heater provided by this embodiment, the water heater further includes a controller (not shown in the figure); the signal input end of the controller is in communication connection with a temperature sensor 6 and/or a water level monitoring meter 7 which are arranged in the water storage cavity; the signal output end of the controller is in communication connection with a first control valve 21 arranged at the water inlet of the plurality of water storage cavities, a second control valve 31 arranged at the water outlet of the water storage cavities and a third control valve 41 arranged at the water outlet of the water storage cavities.
Therefore, the controller controls the first control valve 21 arranged at the water inlet of the hot water host 8 and the water storage cavities, the second control valve 31 arranged at the water outlet of the water storage cavities and the third control valve 41 arranged at the water outlet of the water storage cavities through the water temperature information fed back by the temperature sensor 6 and the water level information fed back by the water level monitoring meter 7. When the water level in the water storage cavity is not changed and the water temperature is reduced, the hot water in the water storage cavity is heated in a circulating heating mode, for example, when the first control valve 21 and the second control valve 31 connected to the first water storage cavity 11 are opened, the water in the first water storage cavity 11 can be heated in a circulating mode; when the water level in the water storage cavity is reduced and the water temperature is kept unchanged, the hot water with lower water temperature in the other water storage cavity can be directly supplemented into the water storage cavity with higher water temperature after being heated, so that the functions of automatic hot water and automatic water supplement of the water heater are realized. For example, when the water level in the third water storage chamber 13 decreases, the second control valve 31 connected to the second water storage chamber 12 and the first control valve 21 connected to the third water storage chamber 13 may be opened to heat the water in the second water storage chamber 12 and supply the heated water to the third water storage chamber 13.
On the basis of the water heater described above, the following describes a control method and a system of the water heater according to this embodiment, in the water heater using the control method of the water heater according to this embodiment, the water heater needs to include a heating chamber and a plurality of water storage chambers communicated with the heating chamber, the heating chamber is further connected with a tap water pipeline, and each water storage chamber is provided with a water outlet, as shown in fig. 2, the control method of the water heater according to this embodiment includes:
s1, obtaining the current water level and the current water temperature of a selected water storage cavity corresponding to a preset water temperature after the user determines the preset water temperature which is urgently needed to be used; it can be understood that the preset water temperatures of all the water storage cavities are different, so that the next judgment needs to be performed according to the preset water temperature which is determined by the user and is urgently needed to determine whether the selected water storage cavity needs to be heated or replenished, and which heating or replenishing operation is specifically selected. For example, when the user selects that the water in the third water storage cavity 13 of the water heater corresponding to the preset water temperature is needed, the current water temperature and the current water level of the water in the third water storage cavity 13 can be obtained through the temperature sensor 6 and the water level monitor 7. The current water level of each water storage cavity is the water level when the water level is kept unchanged within a certain time, for example, when the water level is not changed any more within 5 seconds or other period of time, it is indicated that no water is discharged or drained from the water storage cavity at the moment, and the current water level can be determined.
S2, comparing the current water level of the selected water storage cavity with a preset water level of the selected water storage cavity, and comparing the current water temperature of the selected water storage cavity with the preset water temperature of the selected water storage cavity; it can be understood that, in the control method of the water heater provided by the embodiment, the condition that the water in the selected water storage cavity reaches the preset water level and the preset water temperature is taken as the condition meeting the use requirement of the user. The preset water level may be a water level set by a user when the user uses water for a second time, or may be defaulted as a maximum water level of the selected water storage chamber.
S3, selectively heating or supplementing the water in the selected water storage cavity based on the comparison result; it will be appreciated that the manner of heating or replenishing the water in the selected water storage chamber includes: the water supply object for supplying water to the selected water storage cavity can be selected from tap water and other water storage cavities except the selected water storage cavity, and whether a circulating heating mode is needed or not is adopted, so that the water in the selected water storage cavity finally reaches the preset water level and the preset water temperature quickly, and the requirement of users for urgent water demand is met. Meanwhile, it should be noted that, as long as the selected water storage cavity meets any one of the conditions that the current water level is lower than the preset water level and the current water temperature is lower than the preset water temperature, the water heater can simultaneously start the heating host to heat tap water or water in other water storage cavities and then supply the heated water to the selected water storage cavity, or heat water in the selected water storage cavity in a circulating heating manner. Therefore, although the heating capacity of the water heater is certain, the mode is favorable for fully playing the heating capacity of the water heater, so that the influence on other water storage cavities can be reduced as much as possible when the water in the selected water storage cavity is ensured to quickly reach the preset water level and the preset water temperature.
It should be noted that although the detailed steps of the method of the present invention are described in detail, those skilled in the art can combine, separate and change the order of the above steps without departing from the basic principle of the present invention, and the modified technical solution does not change the basic idea of the present invention and therefore falls into the protection scope of the present invention. For example, the current water level and the current water temperature of the selected water storage cavity may be obtained before the user determines the preset water temperature to be used urgently, and then the next comparison is directly performed based on the selected water storage cavity after the user determines the preset water temperature to be used urgently. Alternatively, the user may obtain the comparison result of the current water levels of all the water storage cavities and the preset water levels thereof and the current water temperatures and the preset water temperatures thereof before determining the selected water storage cavity, and then determine the specific operation thereof directly based on the selected water storage cavity. Thus, it can be understood that performing the operations in the order of steps S1, S2, and S3 described above is a preferred implementation provided by the present embodiment. The technical solutions of those skilled in the art after combining, splitting and exchanging the above steps are the same as the basic principles of the present invention, and therefore, the present invention should also fall into the protection scope of the present invention.
It can be understood that, when the user does not determine the selected water storage cavity corresponding to the preset water temperature which is urgently needed to be used, the water heater performs water heating according to the normal water heating program, the control method of the water heater in the embodiment is not the description of the whole set of control method of the water heater, and similarly, only the engine of the automobile is improved, and other parts of the automobile can be designed according to the prior art in the production and manufacturing of the automobile. Meanwhile, it can be understood that the control method of the water heater of the embodiment is particularly suitable for the situation when hot water with a certain preset water temperature is in urgent need of use, so that the demand of a user on the urgent need of the hot water with the preset water temperature can be met through allocating water and tap water in different water storage cavities under the condition that the hot water capacity of the water heater is certain.
As a preferred embodiment of the above control method provided in this embodiment, the step of "selectively performing heating or supplementing operation to the water in the selected water storage chamber based on the result of the comparison" in step S3 includes: and if the current water level of the selected water storage cavity is less than the preset water level and the current water temperature is less than or equal to the preset water temperature, selecting a water supply object for supplying water to the selected water storage cavity from tap water and other water storage cavities except the selected water storage cavity. It is understood that, in this embodiment, once the selected water storage cavity is determined according to the preset water temperature determined by the user to be urgently needed, the water heater will automatically perform a specific operation according to the control method of this embodiment with the water in the selected water storage cavity reaching the preset water level and the preset water temperature as a primary purpose. In addition, the problem of water demand of a user on other water storage cavities corresponding to the preset water temperature does not need to be considered in the operation process.
As a preferred embodiment of the above control method provided in this embodiment, the step of "selecting a water supply target for supplying water to the selected water storage chamber from tap water and other water storage chambers except the selected water storage chamber" includes: selecting a water storage cavity with the highest current water temperature from other water storage cavities except the selected water storage cavity as a first water supply object, and if the selected water storage cavity does not reach the preset water level after the first water supply object heats all water and supplies the heated water to the selected water storage cavity, continuously selecting the water storage cavity with the highest temperature from the other water storage cavities as the first water supply object until the current water level in the selected water storage cavity is equal to the preset water level; if the water temperature heated by the first water supply object is higher than the preset water temperature of the selected water storage cavity, selecting other water storage cavities or tap water with the water temperature after one-time heating lower than the preset water temperature of the selected water storage cavity as second water supply objects, and simultaneously or alternatively supplying water to the selected water storage cavities through the first water supply objects and the second water supply objects; if the water temperature of the first water supply object after heating is lower than the preset water temperature of the selected water storage cavity, circularly heating the water in the selected water storage cavity when the current water level in the selected water storage cavity reaches the preset water level until the current water temperature of the selected water storage cavity is equal to the preset water temperature.
For example, in the present embodiment, the water storage cavity with the highest current water temperature is selected from the other water storage cavities except the selected water storage cavity as the first water supply object, so as to enable the water in the selected water storage cavity to reach the preset water level and the preset water temperature at the fastest speed; and considering that the water of the first water supply object can be higher than the preset water temperature of the selected water storage cavity after being heated, other water storage cavities or tap water with the water temperature after being heated for one time being smaller than the preset water temperature of the selected water storage cavity are used as second water supply objects, and the water supply proportion or the respective water supply time of the first water supply object and the second water supply object can be adjusted to realize that the water in the selected water storage cavity can just reach the preset water temperature when reaching the preset water level, so that the requirement of users for urgent water demand can be met to the greatest extent. For example, when the second water storage cavity 12 is used as the selected water storage cavity, the third water storage cavity 13 is used as the first water supply object according to the above method, and since the water in the third water storage cavity 13 is heated once and then becomes higher than the preset water temperature of the second water storage cavity 12, the first water storage cavity 11 or the tap water 12 can be used as the second water supply object.
As a preferred embodiment of the above control method provided in this embodiment, the step of "selectively performing heating or supplementing operation to the water in the selected water storage chamber based on the result of the comparison" in step S3 includes: and if the current water level of the selected water storage cavity is equal to the preset water level and the current water temperature is lower than the preset water temperature, circularly heating the water in the selected water storage cavity until the current water temperature of the selected water storage cavity is equal to the preset water temperature. It can be understood that, in this embodiment, no matter the water in the other water storage cavities is heated and then supplied to the selected water storage cavity, or the water in the selected water storage cavity is circularly heated, the water pump provides power for the water flow, so that the water flow enters the selected water storage cavity after being heated once by the water heater.
