In spring and autumn, the water outlet temperature of the water heater 100 is controlled according to the spring and autumn operation information. In summer, the outlet water temperature of the water heater 100 is controlled according to the summer operation information. In winter, the outlet water temperature of the water heater 100 is controlled according to the winter operation information. Therefore, the temperature trend can be reasonably changed in the whole bathing process, the physiological function of the human body is adapted, and the change trend of the environmental temperature and the humidity is adapted.

In the present embodiment, the controller 10 of the water heater 100 is a single chip integrated with a processor, a memory, a communication module, and the like. The processor may refer to a processor included in the controller 10.

The controller 10 may include an MCU (Microcontroller Unit). The controller 10 may be used to provide computing and control capabilities to support the operation of the overall water heater 100. The controller 10 may call the relevant control program instructions to control the control method of the water heater 100 of the present embodiment.

In some embodiments, the water heater 100 is provided with a first preset water inlet temperature, a second preset water inlet temperature, a first preset environment temperature and a second preset environment temperature, the first preset water inlet temperature is less than the second preset water inlet temperature, the first preset environment temperature is less than the second preset environment temperature, and the control method includes:

determining that the seasonal operation information of the water heater 100 is winter operation information under the condition that the inlet water temperature is less than a first preset inlet water temperature or the environment temperature is less than a first preset environment temperature;

determining that the seasonal operation information of the water heater 100 is spring and autumn operation information when the water inlet temperature is greater than or equal to a first preset water inlet temperature and less than or equal to a second preset water inlet temperature or the environmental temperature is greater than or equal to a first preset environmental temperature and less than or equal to a second preset environmental temperature;

in the case where the temperature of the inlet water is greater than the second preset inlet water temperature or the ambient temperature is greater than the second preset ambient temperature, it is determined that the seasonal operation information of the water heater 100 is the summer operation information.

The control method of the above embodiment may be implemented by the controller 10 of the present embodiment that the controller 10 is configured to determine that the seasonal operation information of the water heater 100 is the winter operation information in the case that the inflow water temperature is less than the first preset inflow water temperature, or the ambient temperature is less than the first preset ambient temperature. The controller 10 is configured to determine that the seasonal operation information of the water heater 100 is spring and autumn operation information when the inflow water temperature is greater than or equal to a first preset inflow water temperature and less than or equal to a second preset inflow water temperature, or the ambient temperature is greater than or equal to a first preset ambient temperature and less than or equal to a second preset ambient temperature. The controller 10 is configured to determine that the seasonal operation information of the water heater 100 is the summer operation information in case that the inlet water temperature is greater than the second preset inlet water temperature or the ambient temperature is greater than the second preset ambient temperature.

Therefore, the season operation information is determined to be winter operation information, spring and autumn operation information or summer operation information through the water inlet temperature and the environment, the water outlet temperature of the water heater 100 is controlled according to the determined winter operation information, spring and autumn operation information or summer operation information, the water outlet temperature meeting the bathing requirement and the comfortable sensation of the user can be obtained, and the user experience is good.

Specifically, the spring and autumn operation information comprises a plurality of bathing stages arranged according to time sequence, and each bathing stage corresponds to a temperature interval. The summer operation information comprises a plurality of bathing stages arranged according to time sequence, and each bathing stage corresponds to a temperature interval. The winter operation information comprises a plurality of bathing stages arranged according to time sequence, and each bathing stage corresponds to a temperature interval. In one embodiment, the spring and autumn operation information, the summer operation information and the winter operation information correspond to different outlet water temperature ranges in the same bathing stage. In other embodiments, the outlet water temperature intervals of the same bathing stage corresponding to the spring and autumn operation information, the summer operation information and the winter operation information are also set to be the same according to the actual situation, and are not limited herein.

In one embodiment, the first predetermined inlet water temperature is 15 ℃. The second predetermined inlet water temperature is 22 ℃. The first preset ambient temperature is 15 deg.c. The second preset ambient temperature is 25 ℃.

Referring to fig. 3, in some embodiments, each seasonal operation information includes a first bathing stage, a second bathing stage, a first water outlet temperature interval corresponding to the first bathing stage, and a second water outlet temperature interval corresponding to the second bathing stage, which are set according to a time sequence within a first preset time period; step S60 includes:

step S62, controlling the water heater 100 to operate at the corresponding outlet water temperature in the first outlet water temperature interval under the condition that the water heater 100 is in the first bathing stage;

and step S64, controlling the water heater 100 to operate at the corresponding outlet water temperature in the second outlet water temperature interval under the condition that the water heater 100 is in the second bathing stage.

The control method of the above embodiment can be realized by the water heater 100 of the present embodiment. The steps S62 and S64 can be implemented by the controller 10. The controller 10 is configured to control the water heater 100 to operate at a corresponding outlet water temperature in the first outlet water temperature interval when the water heater 100 is in the first bathing stage, and to control the water heater 100 to operate at a corresponding outlet water temperature in the second outlet water temperature interval when the water heater 100 is in the second bathing stage.

Thus, by controlling the water heater 100 to operate at the outlet water temperatures in different intervals when the water heater 100 is in different bathing stages, the outlet water temperature of the water heater 100 can meet the bathing requirements and comfort of the user.

In one embodiment, the first and second bathing phases may be consecutively arranged bathing phases. Thus, the user can be provided with a good bathing feeling. Specifically, the first bathing stage and the second bathing stage are continuously set bathing stages, and it can be understood that the water outlet of the water heater 100 is continuously uninterrupted in the process of the transition from the first bathing stage to the second bathing stage.

In another embodiment, a break period T is set between the first and second bathing periods, T being greater than 1 min. Therefore, the user can wipe the bath foam shampoo and the like by using the intermittent time T, and the bathing requirements of the user are met.

Specifically, the second bathing stage is a mark for starting the second bathing stage after the first bathing stage is interrupted and suspended for a period of time T. The intermittent duration T is set between the first bathing period and the second bathing period, which can be understood as: in the process of the transition from the first bathing stage to the second bathing stage, the water heater 100 stops discharging water, and the interruption time length of the water discharging stop is T.

Referring to fig. 4, in some embodiments, the plurality of bathing stages further includes a third bathing stage after the second bathing stage, the effluent temperature interval includes a third effluent temperature interval corresponding to the third bathing stage, and step S60 includes:

and step S66, controlling the water heater 100 to operate at the corresponding outlet water temperature in the third outlet water temperature interval under the condition that the water heater 100 is in the third bathing stage.

The control method of the above embodiment can be realized by the water heater 100 of the present embodiment. Here, step S66 may be implemented by the controller 10. The controller 10 is configured to control the water heater 100 to operate at the corresponding outlet water temperature in the third outlet water temperature interval when the water heater 100 is in the third bathing stage.

Therefore, the water outlet temperature of the water heater 100 can be properly provided for the user in the bathing process, so that the healthy bathing requirement and the good comfort level of the user can be met.

In this embodiment, a continuous bath stage is provided between the second bath stage and the third bath stage. Thus, the user can be provided with a good bathing feeling.

In particular, the bath stages arranged continuously and uninterruptedly are arranged between the second bath stage and the third bath stage, which can be understood as follows: in the process of the transition from the second bathing stage to the third bathing stage, the water outlet of the water heater 100 is continuous and uninterrupted.

In this embodiment, when it is determined that the seasonal operation information of the water heater 100 is the summer operation information by the incoming water temperature and the ambient temperature, the water heater 100 is controlled to operate at the corresponding outgoing water temperature in the outgoing water temperature interval corresponding to the bathing stage by the different bathing stages in which the water heater 100 is located. The first outlet water temperature interval of the first bathing stage of the summer operation information is more than or equal to 35 ℃ and less than or equal to 38 ℃. The second outlet water temperature interval of the second bathing stage of the summer running information is more than or equal to 38 ℃ and less than or equal to 41 ℃. The temperature interval of the third outlet water of the third bathing stage of the summer running information is more than or equal to 36 ℃ and less than or equal to 39 ℃.

Specifically, the summer environment temperature is very high, the temperature difference between the water inlet temperature and the environment temperature is small, and the rise amplitude of the environment temperature is small. When a person feels a relatively comfortable state at about 28 ℃ in a naked body, the person can sweat when being heated, the skin temperature in summer is about 34 ℃, the water outlet temperature in the first bathing stage needs to be controlled within the range of 35-38 ℃, in the bathing stage, if the water outlet temperature is lower than 35 ℃, the heat loss is faster than the heat supply in the wet state of the skin, and the person feels cool and has the risk of catching a cold. If the outlet water temperature is higher than 38 ℃, the initial outlet water temperature is hotter, the skin is not easy to accept, the heat is quickly dissipated to the environment, the environment temperature is increased, and the skin temperature is quickly increased, so that discomfort is caused. Therefore, in the first bathing stage, the first outlet water temperature interval is set to [35 ℃, 38 ℃), and the outlet water temperature of the water heater 100 can be any temperature point in the first outlet water temperature interval or a plurality of temperature points which slowly rise in the first outlet water temperature interval.

In one embodiment, the inlet water temperature is 30 ℃, the ambient temperature is 30 ℃, and after the water heater 100 is started, the water heater 100 can determine that the seasonal operation information of the water heater 100 is the summer operation information according to the inlet water temperature and the ambient temperature. The summer operating information includes a summer bathing curve of the water heater 100 outlet temperature versus time. That is, the water heater 100 is controlled to operate in the summer bathing curve after the start of the water heater 100, as shown by the solid line L1 of FIG. 7

The first preset time period is 15 minutes, the first bathing period is 6 minutes, the second bathing period is 5 minutes, and the third bathing period is 4 minutes. Wherein, the first to sixth minutes are the first bathing stage, the temperature of the outlet water of the water heater 100 is set to 37 ℃ in the first minute, 38 ℃ in the second minute, 38 ℃ in the third minute, 38 ℃ in the fourth minute, 38 ℃ in the fifth minute and 39 ℃ in the sixth minute. The second bathing stage is carried out from the seventh minute to the eleventh minute, and the water outlet temperature of the water heater 100 is 40 ℃ in the seventh minute, 40 ℃ in the eighth minute, 40 ℃ in the ninth minute, 40 ℃ in the tenth minute and 39 ℃ in the eleventh minute. The twelfth to fifteenth minutes are the third bathing period, and the outlet water temperature of the water heater 100 is set to 39 ℃ in the twelfth minute, 38 ℃ in the thirteenth minute, 38 ℃ in the fourteenth minute and 38 ℃ in the fifteenth minute.

In this case, if the user feels the water somewhat cool in the first minute, adjusting the temperature of the water heater 100 to 39 ℃, the summer bath curve is modified to: the outlet water temperature of the water heater 100 was set at 38 ℃ for the first minute, 39 ℃ for the second minute, 39 ℃ for the third minute, 39 ℃ for the fourth minute, 39 ℃ for the fifth minute, and 40 ℃ for the sixth minute. The seventh minute was 41 deg.C, the eighth minute 41 deg.C, the ninth minute 41 deg.C, the tenth minute 41 deg.C, the eleventh minute 40 deg.C. The twelfth minute was set to 40 deg.C, the thirteenth minute to 39 deg.C, the fourteenth minute to 39 deg.C, and the fifteenth minute to 39 deg.C.

In this embodiment, when it is determined that the seasonal operation information of the water heater 100 is the winter operation information according to the incoming water temperature and the ambient temperature, the water heater 100 is controlled to operate at the corresponding outgoing water temperature in the outgoing water temperature interval corresponding to the bathing stage by using the different bathing stages in which the water heater 100 is located. Specifically, the environmental temperature is lower in winter, the temperature difference between the water inlet temperature and the environmental temperature is larger, the body feeling is very cold when a user is naked before bathing, even the user needs to shake to generate heat and warm, the skin temperature is obviously reduced before bathing, and relatively higher temperature is needed for heating the environmental temperature and providing proper heat for the skin at the beginning of bathing. The water inlet temperature is below 15 ℃ in winter, the skin temperature covered by clothes is generally about 33 ℃ under the winter environmental condition, the naked skin is about 28 ℃ in the ground, the average skin temperature is about 30 ℃ in the naked body waiting bathing process before bathing, the cold environmental temperature and the lower skin temperature need to be heated by the water inlet temperature, but the high temperature difference between the water inlet temperature and the skin temperature can cause the skin to be uncomfortable, the skin temperature is personal, but the temperature difference between the water inlet temperature and the skin temperature exceeds 10 ℃, and the skin can generate uncomfortable stimulation feeling.

In winter, the temperature of the inlet water in the first bathing stage is controlled within 39-40 deg.C, and if the temperature of the inlet water is lower than 39 deg.C, the cold environment can not obtain enough heat, so as to relieve the cold bathing environment. If the water inlet temperature is higher than 40 ℃, the water inlet temperature is too hot and exceeds the acceptable temperature difference range, the skin is not easy to accept, and the skin irritation is large. Therefore, in the first bathing stage, the first outlet water temperature interval is set to [39 ℃, 40 ℃), and the outlet water temperature of the water heater 100 can be any temperature point in the first outlet water temperature interval or a plurality of temperature points which slowly rise in the first outlet water temperature interval.

The temperature rise of the second bathing stage is set at 40-43 deg.c, i.e. the second outlet temperature interval is preferably set at [40 deg.c, 43 deg.c ], and the outlet temperature of the water heater 100 may be any temperature point in the first outlet temperature interval, or may be a plurality of temperature points in the first outlet temperature interval which slowly rise. The temperature difference between the outlet water temperatures of the water heater 100 during the second bath stage, which are continuously changed twice before and after, should not exceed 1 deg.c. The second bathing stage is a relatively high temperature outlet process in which the ambient temperature and humidity are rapidly raised and the body is warm, which is not likely to last too long in winter or increase the physical burden, especially in patients with cardiopulmonary insufficiency.

Preferably, the third outlet temperature interval is set at [40 ℃, 39 ℃), and the outlet temperature of the water heater 100 may be any temperature point in the third outlet temperature interval or a plurality of temperature points in the third outlet temperature interval that slowly decrease. The temperature difference between the outlet water temperatures of the water heater 100 continuously changed twice before and after the third bath stage should not exceed 1 ℃.

It should be noted that the change of the outlet water temperature of the whole winter bathing curve is a slow adjusting process, and is not directly adjusted from 39 ℃ to 41 ℃ and 42 ℃, and the temperature difference of the outlet water temperature continuously changed from the first time to the second time of the water heater 100 in each bathing stage process should not exceed 1 ℃.
