Detailed Description
The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.
Referring to fig. 1 and 2, an embodiment of the present invention provides a control method for a gas water heater, including:
identifying identity information of a user at a control end of the gas water heater;
when a water using end selection instruction is received, acquiring water using end information, acquiring corresponding water using parameters according to the identity information and the water using end information, and predicting a target temperature value according to the water using parameters;
and when the temperature adjusting instruction is received, controlling the temperature setting value not to exceed the target temperature value.
According to the control method of the gas water heater, when a user wants to set the temperature, unlocking can be performed through the identity information, the gas water heater identifies the identity information of the user, then the user selects the water using end, the gas water heater receives the water using end selection instruction to obtain the water using end information, corresponding water using parameters are obtained according to the identity information and the water using end information, and the target temperature value is predicted according to the water using parameters; when the user adjusts the set temperature, the gas water heater receives the temperature adjustment instruction, and the temperature set value is controlled not to exceed the target temperature value, so that the user cannot set the temperature higher than the target temperature.
The target temperature value is the highest temperature which can be heated by the gas water heater and is predicted according to the water consumption parameters of the user at the water consumption end, the target temperature value is set according to different water consumption parameters of each user at different water consumption ends, and the problem that the outlet water temperature is not consistent with the set temperature of the user in the prior art is solved.
The identification information for identifying the user may be fingerprint identification, face identification or voice identification, which is not limited herein. Taking fingerprint identification as an example, each user can register and input own fingerprint information before using the gas water heater. When the user uses the gas water heater, the fingerprint is used for unlocking the gas water heater, the gas water heater acquires the fingerprint information of the user and compares the fingerprint information with the prestored fingerprint stored in the database, if the fingerprint information is matched with the prestored fingerprint, the gas water heater is unlocked, otherwise, the gas water heater displays warning information and continues to be in a state of receiving the fingerprint information. The display warning information may be "the fingerprint does not exist" or "please change the finger".
After the gas water heater is unlocked, a user selects a water using end according to the prompt of the gas water heater, and the water using end communicated with the gas water heater is stored in the gas water heater in advance. For example, if the user sets the temperature for kitchen use, the user selects "kitchen end", and if the user sets the temperature for bath use, the user selects "bath end". Of course, the purpose of setting the temperature at this time can be to use water at a plurality of water using ends, and a 'bathing end' with larger water consumption can be selected.
The gas water heater receives the water using end selection instruction, acquires water using end information, acquires corresponding water using parameters according to the identity information and the water using end information, and predicts a target temperature value according to the water using parameters. If the water consumption end information is a bathing end, the corresponding water consumption parameters are bathing parameters, and the bathing parameters comprise bathing temperature and bathing water flow.
And acquiring corresponding water use parameters according to the identity information and the water use end information, wherein the water use parameters corresponding to the identity information and the water use end information are pre-stored in a database when a user registers. For example, if the bathing temperature of the bathing end is set to be a1 and the bathing water flow is set to be a2 during the registration of the user a, the target temperature value set for the user a this time is predicted according to a1 and a2, and the target temperature value is assumed to be 60 degrees. When the user adjusts the temperature of the gas water heater, the gas water heater receives a temperature setting instruction and controls the temperature setting value not to exceed the target temperature value.
The water using end of the gas water heater is provided with a water outlet valve, a temperature sensor, a flow sensor and an identification device, the water outlet valve can be opened after the user identity is identified, and the temperature sensor and the flow sensor can detect the water temperature and the water flow after the water outlet valve is opened. Wherein, at the water end of gas heater, after discerning user's identity success, the outlet valve just can go out water.
And acquiring corresponding water use parameters according to the identity information and the water use end information, and analyzing and integrating according to the historical water use parameters of the user at the water use end to acquire a target temperature value. Specifically, identity information of a user is identified at a water consumption end of the gas water heater, water consumption parameters are recorded when water is consumed, and the water consumption end information, the identity information and the water consumption parameters are correspondingly stored. And when the user sets the temperature at the control end of the gas water heater, the recorded water use parameters are called.
The identification information for identifying the user may be fingerprint identification, face identification or voice identification, which is not limited herein. Taking fingerprint identification as an example, at a water using end, the water outlet valve is unlocked by using a fingerprint, the water outlet valve acquires fingerprint information of a user, the fingerprint information is compared with prestored fingerprints stored in a database, if the fingerprint information is matched with the prestored fingerprints, the water outlet valve is unlocked, and if not, the water outlet valve does not discharge water or displays warning information.
Recording water usage parameters including: and detecting the temperature of the water for one time and the corresponding flow rate of the water for one time at each water using end at each water using process at set intervals, accumulating the duration of each water using temperature, and recording the water using temperature with the longest duration and the corresponding flow rate of the water as water using parameters when each water using process is finished. If the user uses water at a certain temperature for the longest duration time, the temperature is most suitable for the user, and the water temperature with the longest duration time and the corresponding water flow are used as water using parameters, so that the requirements of the user are better met.
If the water flow corresponding to one water temperature is changed in the water using process, the maximum water flow corresponding to the water temperature is selected as the water using parameter record.
Because each user has multiple times of water consumption at one water consumption end, the water consumption parameters have multiple groups, and one group with the highest water consumption temperature or the highest water consumption flow in the multiple groups of data can be called. In order to avoid the situation that the data occupy too much memory and the situation that the data storage time is too long and the current actual situation is inconsistent, in the embodiment, the water usage parameter recorded each time is covered with the water usage parameter recorded last time, so that the water usage parameter keeps timeliness and is more in line with the latest water usage habit of the user.
Controlling the temperature setting to not exceed the target temperature value, comprising: and after the temperature setting value is equal to the target temperature value, if the user continues to adjust the temperature-rising button and the gas water heater receives a temperature-increasing instruction, displaying the target temperature value and prompt information for prompting that the current temperature setting value is the highest temperature.
The temperature setting value is divided into a plurality of temperature areas from low to high, and in each temperature area, the temperature setting value does not exceed the maximum temperature value of the temperature area. Specifically, the plurality of temperature zones include a low temperature zone, a normal temperature zone, and a high temperature zone, for example, the adjustable temperature range of the normal temperature zone is 38 to 55 ℃, the adjustable temperature range of the low temperature zone is 30 to 37 ℃, and the adjustable temperature range of the high temperature zone is 56 to 70 ℃. When the temperature setting value is in the normal temperature region, the temperature setting value does not exceed 55 ℃, provided, of course, that the temperature setting value does not exceed the target temperature value. Wherein, the display temperature of the gas water heater is an integer.
When a temperature zone adjustment instruction is received, the temperature setting value can be switched to a different temperature zone. The user can select the temperature zone on the gas water heater, and the gas water heater receives the temperature zone adjusting instruction and switches the temperature zone. For example, when the temperature region is switched from the normal temperature region to the high temperature region, the temperature setting value is a certain default value in the high temperature region. The purpose of this is to facilitate rapid temperature regulation. For example, the current temperature setting is 40 ℃, if the user wants to adjust to 60 ℃, the user can switch to the high temperature region first and then increase the temperature, and if the user mechanically increases from 40 ℃ to 60 ℃, the button pressing time is long.
The control end of the gas water heater is provided with a temperature display area, and before a temperature adjusting instruction is received, the temperature display area displays a default temperature value which is not higher than a target temperature value. Specifically, the default temperature value may be a certain temperature value in the normal temperature region. After receiving the temperature adjustment instruction, the temperature display area displays the current temperature setting value, and the prompt message can be displayed on one side of the temperature setting value.
When the current temperature setting value is lower than the target temperature value, the current temperature setting value is displayed, and after the current temperature setting value is equal to the target temperature value, if the user continues to adjust the temperature-rising button, the gas water heater receives a temperature-increasing instruction and displays the target temperature value and prompt information.
The water flow rate mentioned in the present embodiment refers to the water flow rate per unit time.
In addition, after the identity information of the user is identified, whether the user is a new user can be judged, if so, the water use parameter of the user does not exist in the database, and at the moment, the default parameter can be adopted as the water use parameter. Specifically, the default parameter may be stored in the database, and when the user is a new user, the default parameter is called as the water usage parameter to obtain the target temperature value.
The embodiment of the invention also provides a gas water heater, which is controlled by adopting the control method of the gas water heater. The structure of the gas water heater is not limited herein.
The foregoing embodiments are merely illustrative of the principles and features of this invention, which is not limited to the above-described embodiments, but rather is susceptible to various changes and modifications without departing from the spirit and scope of the invention, which changes and modifications are within the scope of the invention as claimed.
