Background

The heating process of the air energy water heater on the domestic water generally needs to be heated for a long time to reach the preset temperature, and the water is often heated by starting up in advance.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to specific embodiments of the present invention and corresponding drawings. It will be apparent that the described embodiments are only some, but not all, embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

It should be noted that the terms "first," "second," and the like in the description and the claims of the present invention and the above figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the invention described herein may be implemented in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

The invention provides a control method of a water heater. The method is implemented in a water heater, for example, in a controller of the water heater.

FIG. 1 is a schematic diagram of a control method of a water heater according to an embodiment of the present invention.

As shown in fig. 1, according to one embodiment of the present invention, the control method of the water heater at least includes steps S110 to S150.

Step S110, when a wireless connection signal of the bound mobile device is received and the wireless connection with the bound mobile device is successful, judging whether the water heater has a water record for use currently.

Specifically, the water heater is bound with the mobile device in advance, and the mobile device is a portable or wearable device, specifically, a mobile terminal (such as a mobile phone) or a wearable device (such as a smart bracelet or a smart watch). For example, the wireless connection signal may be a bluetooth connection signal or a WiFi connection signal, for example, because the wireless connection signal is bound by bluetooth pairing or by a device identification identifier, and WiFi communication may be performed after the binding. The wireless connection signal is a trigger signal for starting the water heater for heating water or not in non-reserved time. When the wireless connection signal of the bound mobile equipment is not received, the original setting operation of the water heater is kept; and when the wireless connection signal of the bound mobile device is detected and the connection with the mobile device is successful (for example, when the Bluetooth connection signal of the paired device is detected and the connection is successful), starting the control of the heating water, and entering the logic judgment of the heating water.

When the wireless connection signal of the bound mobile equipment is received and the wireless connection is successful, judging whether the water heater has a water record for habit currently. The custom water record may specifically include: the habit of using hot water at the same time is that the water is used for n consecutive days; when the water use time of the hot water used in two adjacent days is within a preset time, the hot water is used at the same time.

Specifically, the daily water use time, i.e. the start water use time, is recorded, the time interval between two times of water use is not longer than the first preset time t1 (min) and is recorded as 1 time of water use, the time interval between two times of water use is longer than the first preset time t1 (min), and the recorded water use time can be recorded as the morning (AM) and afternoon (PM), for example, t _AM1 、t _AM2 、t _AM3 、…、t _PM1 、t _PM2 、t _PM3 …. And if the water using time of the hot water in the continuous n days is within the difference of t2 time, recording the same time and recording the water using time as the habit water using time, and recording the water using time of the last day in the continuous n days as the habit water using time. For example, within ±t2 (the unit may be, for example, min) of the previous day, the water use time+1 is recorded, and the 3-day mark is recorded as the custom water. That is, the water use time of the hot water for n consecutive days is within t2, and the same time is recorded. For example, the preset time t2 is 10min, the water using time recorded in the previous day is 15:00, the current (today) water using time is 15:09, and the difference is within 10min, the use of hot water at the same time is considered . Preferably, the custom water record is cleared when no hot water is used for the custom water time for n consecutive days. For example, when hot water is not turned on for a period of custom water for 3 consecutive days, the custom water record is cleared. If the water heater is started for the first time at present, no water is used for recording and no water is used for recording because the water heater is unused.

And step S120, if the water heater is judged to be currently used for water record, judging whether the water heater is currently reserved for hot water setting or not.

Specifically, if the water heater does not have the water record for habit at present, judging whether the water heater has reserved hot water setting at present, namely whether the water heater is started in a reserved mode. If the water heater is judged to have reserved hot water setting and is timing, the current reserved hot water control operation is kept so as to meet the reserved water requirement of a user.

And step S130, if the water heater is not currently used for water recording and reserved hot water setting is not performed, controlling the operation of the water heater according to whether water recording exists and/or the temperature difference value between the current set water temperature and the water temperature of the water tank.

Specifically, if the water heater is currently free of a custom water record and has no reserved hot water setting, judging whether a water record exists, wherein the water record comprises: time T of starting hot water at last time _{Recording with water} The heating time (time from the start to the stop of heating) K at the last time of heating water, and the rising temperature of the water tank at the last time of heating water (the rising temperature T from the rising temperature of the water tank at the start of heating water to the set water temperature) _{Is provided with} -T _{Opening device} ，T _{Is provided with} To set the water temperature, T _{Opening device} To start heating the water temperature of the water tank), the rising time t for every rising of the water temperature of the water tank by a preset temperature value at the last time of heating the water _{Lifting device} ，t _{Lifting device} ＝(T _{Is provided with} -T _{Opening device} ) The unit of/K is, for example, min/. Degree.C.

The method comprises the following two cases:

(1) If no water is used for recording, judging whether the temperature difference value between the current set water temperature and the water temperature of the water tank reaches a preset temperature difference threshold value or not; if the temperature difference value between the current set water temperature and the water temperature of the water tank is judged not to reach the preset temperature difference threshold value, controlling the water heater to keep the current state; and if the temperature difference value between the current set water temperature and the water temperature of the water tank reaches the preset temperature difference threshold value, controlling the water heater to start heating water to operate, and recording the current heating water time.

For example, the preset temperature difference threshold is X1 ℃, if no hot water setting is reserved (i.e. no start-up is reserved) and no water is recorded (i.e. no start-up time is recorded), the current set water temperature T is detected _{Is provided with} With water temperature T of water tank _{Water and its preparation method} Temperature difference Δt=t of (2) _{Is provided with} -T _{Water and its preparation method} If DeltaT<Maintaining the current state at X1 ℃; if the delta T is more than or equal to X1 ℃, starting the operation of heating water, and recording the heating water time period, thereby meeting the hot water requirement of users. When detecting the water temperature T of the water tank _{Water and its preparation method} Equal to the set water temperature T _{Is provided with} When meeting T _{Water and its preparation method} ＝T _{Is provided with} And stopping heating the water.

(2) If the water is recorded, the time T of starting hot water is recorded according to the current time and the last time hot water is used _{Recording with water} The predicted heating water time T when the current heating water reaches the set water temperature from the current water temperature of the water tank _{Hot water time} And controlling whether the water heater is started to produce hot water or not according to whether the temperature difference between the current set water temperature and the water temperature of the water tank reaches a preset temperature difference threshold value.

Specifically, according to the starting hot water time T at the last hot water use _{Recording with water} The predicted hot water making time T _{Hot water time} Determining the heating water starting time required by the time which is the same as the starting hot water time when the hot water is used last time when the current water temperature of the water tank reaches the set water temperature; and if the current time is later than or equal to the heating water starting time and the temperature difference between the current set water temperature and the water temperature of the water tank reaches a preset temperature difference threshold (delta T is more than or equal to X1 ℃), controlling the water heater to start heating water to operate. For example, the hot water time T for starting the last time the hot water was used _{Recording with water} For 19:00, the time required to warm water from the current tank water temperature to reach the set water temperature is 30min, so the same time as the last warm water use time is required for 19:00 reaches the set water temperature, at the latestTo start heating water at 18:30, therefore, if the current time is 18:30 or later than 18:30, the heating water operation needs to be started immediately. If the current time is earlier than the heating water starting time, the heating water operation is started when the heating water starting time is reached, and electric energy can be saved.

The predicted heating time T for the heating water to reach the set water temperature from the current water temperature of the water tank _{Hot water time} The temperature is determined according to the heating time (time from the start to the stop of heating) K of the last time of heating water, the temperature rise of the water temperature of the last time of heating water and the temperature difference between the current set water temperature and the water temperature of the water tank. Specifically, according to the ratio of the heating time K of the last hot water and the rising temperature of the water temperature of the last hot water, the rising time t for each rising preset temperature value of the water temperature of the water tank of the last heating is determined _{Lifting device} Then according to the temperature difference between the current set water temperature and the water temperature of the water tank and the rising time t used for each rising preset temperature value of the water temperature of the water tank when the water is heated last time _{Lifting device} Determining the predicted hot water producing time T of the present time when the water temperature of the present water tank reaches the set water temperature _{Hot water time} . Namely T _{Hot water time} (min)＝t _{Lifting device} *△T。

Heating time k=t for last hot water use _{Heating water heater} -t _{Heating water stop} ，t _{Heating water heater} For heating water, h is min, t _{Heating water stop} Stopping heating water for a period of time, and the period of time is h is min. The temperature rising of the water temperature when the hot water is used last time is from the water temperature T of the water tank when the water starts to be heated _{Opening device} Rising to a set water temperature T _{Is provided with} Upper temperature of (T) _{Is provided with} -T _{Opening device} ) The rising time t for every rising of the water temperature of the water tank by a preset temperature value when the water is heated last time _{Lifting device} ＝(T _{Is provided with} -T _{Opening device} ) K, for example, in min/DEG C, for example, the rise time for each rise in temperature of 1 ℃; according to the rising time t for every rising preset temperature value of the water temperature of the water tank when the water is heated last time _{Lifting device} And the product of the current set temperature and the temperature difference delta T of the water temperature of the water tank, determining the predicted water heating time T of the water heating time for the water temperature of the water tank to reach the set water temperature _{Hot water time} T, i.e _{Hot water time} ＝t _{Lifting device} * Deltat. The comparison of the time before and the time after is twenty-four hour system time or twelve hour system time, namely, different dates only compare the time before and the time after and do not compare the date before and the time after. For example, 19:05 of the previous day is compared to 19:00 of today, then 19:00 of today is earlier than 19:05 of the previous day.

For example, the current time t _{Currently, the method is that} When hot water is set without reservation (without reservation for starting up) but useful water is available (i.e. there is a start-up time record), according to t _{Currently, the method is that} ≥(T _{Recording with water} -T _{Hot water time} ) And the delta T is more than or equal to X1 ℃ for starting the heating water, and the heating water is used for judging the starting of the heating water according to the last water use time of a user. When detecting the water temperature T of the water tank _{Water and its preparation method} Equal to the set water temperature T _{Is provided with} When meeting T _{Water and its preparation method} ＝T _{Is provided with} And stopping heating the water.

And step S140, if the water heater is judged to have the current water using record, judging whether the water heater has reserved hot water setting currently.

Specifically, if the water heater has a water record for habit, judging whether the water heater has reserved hot water setting currently, namely whether the water heater is started in a reserved mode. If the water heater has the current water using record and reserved hot water setting and is timing, the current reserved hot water making control operation is kept, and the initial hot water setting water temperature requirement of a user is ensured.

Step S150, if the water heater has a current water usage record and no reserved hot water setting, according to the recorded water usage time t _{Water for habit} And controlling the operation of the water heater by the temperature difference value between the current set water temperature and the water temperature of the water tank.

Specifically, according to the current time and the predicted heating water time T when the heating water reaches the set water temperature from the current water temperature of the water tank _{Hot water time} Determining the expected time for heating water to reach the set water temperature from the current time; if the water is used for a period of time t _{Water for habit} And if the preset temperature difference value is earlier than or equal to the determined expected time and the temperature difference value between the current set water temperature and the water temperature of the water tank reaches the preset temperature difference threshold value, controlling the water heater to start the operation of heating water.

For example, the habit of using water for time t _{Water for habit} For 19:00, the time required for heating water from the current water tank water temperature to reach the set water temperature is 30min, so if the set water temperature is about to reach before the habit water use time is 19:00 or 19:00, the heating water operation is started if the estimated time for heating water from the current time to reach the set water temperature is determined to be 19:00, namely, the heating water operation is started when the current time reaches 18:30.

Wherein the current predicted heating water time T when the current heating water reaches the set water temperature from the current water tank water temperature _{Hot water time} The temperature is determined according to the heating time (time from the start to the stop of heating) K of the last time of heating water, the temperature rise of the water temperature of the last time of heating water and the temperature difference between the current set water temperature and the water temperature of the water tank. Specifically, according to the ratio of the heating time K of the last hot water and the rising temperature of the water temperature of the last hot water, the rising time t for each rising preset temperature value of the water temperature of the water tank of the last heating is determined _{Lifting device} Then according to the temperature difference between the current set water temperature and the water temperature of the water tank and the rising time t used for each rising preset temperature value of the water temperature of the water tank when the water is heated last time _{Lifting device} Determining the predicted hot water producing time T of the present time when the water temperature of the present water tank reaches the set water temperature _{Hot water time} . Namely T _{Hot water time} (min)＝t _{Lifting device} *△T。

Heating time k=t for last hot water use _{Heating water heater} -t _{Heating water stop} ，t _{Heating water heater} For heating water, h is min, t _{Heating water stop} And (5) stopping heating water for a period of time, wherein h is min. The temperature rising of the water temperature when the hot water is used last time is from the water temperature T of the water tank when the water starts to be heated _{Opening device} Rising to a set water temperature T _{Is provided with} Upper temperature of (T) _{Is provided with} -T _{Opening device} ) The rising time t for every rising of the water temperature of the water tank by a preset temperature value when the water is heated last time _{Lifting device} ＝(T _{Is provided with} -T _{Opening device} ) K, for example, in min/DEG C, for example, the rise time for each rise in temperature of 1 ℃; according to the rising time t for every rising preset temperature value of the water temperature of the water tank when the water is heated last time _{Lifting device} At the current set temperatureThe product of the temperature difference delta T of the temperature and the water temperature of the water tank is used for determining the predicted hot water making time T of the water tank for making the water temperature of the water tank reach the set water temperature _{Hot water time} T, i.e _{Hot water time} ＝t _{Lifting device} * Deltat. For example, t _{Water for habit} ≤t _{Currently, the method is that} +T _{Hot water time} And the DeltaT is more than or equal to X1 ℃ to start heating water. The comparison of the time before and the time after is twenty-four hour system time or twelve hour system time, namely, different dates only compare the time before and the time after and do not compare the date before and the time after.

Preferably, based on the above embodiment, the method further includes: if the water heater has a water recording for habit and does not reserve hot water setting, determining a time period in which the current time is positioned when controlling the water heater to heat water to run; determining the current water temperature requirement of the water heater according to the determined time period of the current time; and determining the current heating water stop water temperature of the water heater according to the determined current water temperature requirement and the set water temperature of the water heater, so as to control the heating water operation of the water heater according to the current heating water stop water temperature.

And the water heating stop water temperature of the water heater is equal to the set water temperature minus the correction temperature corresponding to the current water temperature demand. The different time periods correspond to different water temperature requirements, and the water temperature requirements are divided into at least two water temperature requirements according to the water temperature, for example, the water temperature requirements can comprise a high temperature requirement, a medium temperature requirement and a low temperature requirement. The different water temperature demands corresponding to different time periods are determined according to the historical unit time used hot water quantity of different time periods, and the higher the unit time used hot water quantity is, the higher the water temperature demand (namely the higher the temperature is).

For example, different people have different habits of using hot water, which is mainly represented by different hot water using time and single hot water using amount, so that the user who is used to use hot water in different time periods can be determined according to the hot water using amount in unit time of the time periods, for example, the different people can include: old people, children, men and women. The higher the amount of hot water used per unit time, the higher the water temperature demand, and the higher the water temperature that needs to be reached for producing the hot water. Thus, the water temperature requirements of different time periods are determined by recording the amount of hot water used in different time periods, thereby determining the people who are habitually using hot water in different time periods.

As shown in fig. 4, the control device 100 includes: the first judging unit 110, the second judging unit 120, the first control unit 130, the third judging unit 140, and the second control unit 150.

The first judging unit 110 is configured to judge whether the water heater has a record of water usage currently when a wireless connection signal of the bound mobile device is received and the wireless connection with the bound mobile device is successful.

Specifically, the daily water use time, i.e. the time of starting to use hot water, is recorded, between two times of water useThe water consumption time is recorded 1 time when the interval of time does not exceed the first preset time t1 (min), the water consumption time is recorded respectively when the interval of time exceeds the first preset time t1 (min), and the recorded water consumption time can be recorded according to the morning (AM) and afternoon (PM) every day, for example, t _AM1 、t _AM2 、t _AM3 、…、t _PM1 、t _PM2 、t _PM3 …. And if the water using time of the hot water in the continuous n days is within the difference of t2 time, recording the same time and recording the water using time as the habit water using time, and recording the water using time of the last day in the continuous n days as the habit water using time. For example, within ±t2 (the unit may be, for example, min) of the previous day, the water use time+1 is recorded, and the 3-day mark is recorded as the custom water. That is, the water use time of the hot water for n consecutive days is within t2, and the same time is recorded. For example, the preset time t2 is 10min, the water using time recorded in the previous day is 15:00, the current (today) water using time is 15:09, and the difference is within 10min, and then the hot water is used at the same time. Preferably, the custom water record is cleared when no hot water is used for the custom water time for n consecutive days. For example, when hot water is not turned on for a period of custom water for 3 consecutive days, the custom water record is cleared. If the water heater is started for the first time at present, no water is used for recording and no water is used for recording because the water heater is unused.

Degree.C.

For example, the hot water time T for starting the last time the hot water was used _{Recording with water} For 19:00, the time required to warm water from the current tank water temperature to reach the set water temperature is 30min, so the same time as the last warm water use time is required for 19:00 reaches the set water temperature, and heating water is required to start at 18:30 at the latest, so if the current time is 18:30 or later than 18:30, the heating water operation is required to be started immediately.
