Referring to fig. 1 to 3, the embodiment of the present application provides a water heater, which includes a water tank 10, a first temperature sensor 20, a second temperature sensor 40, and a control unit 30. Wherein the first temperature sensor 20 and the second temperature sensor 40 are installed at intervals in the height direction of the water tank 10 to the water tank 10, wherein the first temperature sensor 20 is in a normally open state. The control unit 30 is electrically connected to the first temperature sensor 20 and the second temperature sensor 40. The control unit 30 includes a power module 310, a detection module 320, and a switching module 330. The power module 310 is configured with a mains power access module and a reserve power access module, which are respectively used for connecting the mains power and the reserve power. The detection module 320 is electrically connected to the power module 310, and is configured to detect whether a reserve power supply is connected. The switching module 330 is electrically connected to the detecting module 320 and the second temperature sensor 40, and is configured to switch the power supply mode of the power module based on the power-on signal of the reserve power supply, and switch the second temperature sensor 40 to the on state based on the power-on of the reserve power supply.
In the present embodiment, by disposing the first temperature sensor 20 and the second temperature sensor 40 along the height direction of the water tank 10 to measure the water temperatures at a plurality of positions in the height direction of the water tank 10, the accuracy of water temperature measurement is improved, and the measured water temperature is made closer to the actual water temperature inside the water tank 10. The second temperature sensor 40 is switched to the on state based on the connection of the reserve power supply, so that the excessive power consumption of the mains supply caused by the fact that the second temperature sensor is started in the mains supply mode is avoided. The water heater can save energy and measure accuracy.
It is understood that the power module 310 is used for supplying power to the whole water heater. The utility power access module constructed on the power module 310 is used for connecting the utility power, and the reserve power access module constructed on the power module 310 is used for connecting the reserve power. Thus, the power module 310 has a mains mode and a reserve power mode.
When the detecting module 320 detects that the reserve power is connected, the switching module 330 of the control unit 30 makes the water heater operate in the reserve power mode. In this mode, the mains is disconnected and power is supplied only by the reserve power supply, and both the first temperature sensor 20 and the second temperature sensor 40 are in an on state. By simultaneously measuring the water temperature inside the water tank 10 by the first temperature sensor 20 and the second temperature sensor 40, the accuracy of water temperature measurement is improved, and the measured water temperature is made to be closer to the actual water temperature inside the water tank 10. Meanwhile, the commercial power is not used after the reserve power supply is connected, so that the power consumption of the commercial power is reduced, and the use cost of the water heater is reduced.
When the detecting module 320 detects that the reserve power is not connected, the switching module 330 of the control unit 30 makes the water heater operate in the mains supply mode. In this mode, the reserve power is disconnected, supplied only by mains, the first temperature sensor 20 is in an on state, and the second temperature sensor 40 is in an off state. The water temperature in the water tank 10 is measured by the first temperature sensor 20, so that the excessive consumption of the commercial power and the increase of the electricity cost are avoided.
It will be appreciated that both the first temperature sensor 20 and the second temperature sensor 40 are used to measure the temperature of the water inside the tank 10. Wherein the first temperature sensor 20 and the second temperature sensor 40 may be the same type of water temperature sensor. It is sufficient to ensure that the first temperature sensor 20 and the second temperature sensor 40 can measure the water temperature inside the water tank 10, and the embodiment of the present application does not limit the types of the first temperature sensor 20 and the second temperature sensor 40.
Wherein the second temperature sensor 40 may be provided as one or at least two. When the second temperature sensors 40 are provided in at least two, the at least two second temperature sensors 40 are spaced apart in the height direction of the water tank 10.
As shown in fig. 1, the water tank 10 is a water storage mechanism at the lower part of the water heater, and the control unit 30 is a head part at the upper part of the water heater. The power module 310 in the control unit 30 corresponds to a power circuit, and the power circuit has a mains interface and a reserve power interface, which are respectively used as a mains access module and a reserve power access module. The detection module 320 of the control unit 30 corresponds to a signal detection circuit, when it captures an electrical signal of the reserve power supply at the reserve power supply interface, it is determined that the reserve power supply is connected, otherwise, the reserve power supply is not connected. The switch module 330 of the control unit 30 corresponds to a switch for controlling the on/off of the second temperature sensor 40. Specifically, when the detection module 320 captures an electrical signal of the reserve power supply, the switching module 330 switches the second temperature sensor 40 to an on state; when the detection module 320 does not capture the electrical signal of the reserve power supply, the switching module 330 switches the second temperature sensor 40 to the off state.
In some embodiments, the water heater further includes a heating unit 50. The heating unit 50 is installed at the water tank 10 to heat water stored in the water tank 10. The heating unit 50 is electrically connected to the power module 310, and is configured to supply power to the heating unit 50 through the power module 310, so as to ensure that the heating unit 50 can electrically heat the water in the water tank 10.
In some embodiments, the heating unit 50 corresponds to a compressor of a water heater. The water heater is an air-powered water heater, and heats water stored in the water tank 10 by a compressor. In other embodiments of the present application, the heating unit 50 may be an electric heating rod, etc., and may be capable of heating the water tank 10.
As shown in fig. 3, in some embodiments, the control unit 30 further includes a temperature setting module 340 and a start-stop module 350. The temperature setting module 340 is used for setting a target water temperature of the water tank 10. The start-stop module 350 is electrically connected to the heating unit 50, and the start-stop module 350 drives the heating unit 50 to start or stop based on comparison between the measured water temperature parameters fed back by the first temperature sensor 20 and the second temperature sensor 40 and the target water temperature parameters of the temperature setting module 340.
It is understood that, based on the target water temperature parameter set by the temperature setting module 340, the start-stop module 350 of the control unit 30 drives the heating unit 50 to start. Along with the continuous heating of the heating unit 50, the water temperature inside the water tank 10 continuously rises, and when the measured water temperature parameter reaches the target water temperature parameter of the temperature setting module 340, the start-stop module 350 of the control unit 30 drives the heating unit 50 to stop heating.
The comparison between the measured water temperature parameter and the target water temperature parameter of the temperature setting module 340 is to compare whether the measured water temperature parameter reaches the target water temperature parameter. If the measured water temperature parameter does not reach the target water temperature parameter, the heating unit 50 is not operated, and the heating unit 50 is in a continuously heated state. If the measured water temperature parameter exceeds the target water temperature parameter, the start-stop module 350 drives the heating unit 50 to stop heating, so as to avoid increasing power consumption and scalding the user due to overheat of the water temperature.
The control unit 30 also has a comparator circuit or comparator. The comparator can compare the measured water temperature parameter with the target water temperature parameter, and feed back the comparison result to the control unit 30, and the control unit 30 enables the start-stop module 350 to control the start-stop of the heating unit 50 based on the comparison result.
In some embodiments, the temperature setting module 340 corresponds to a touch screen mounted on the surface of the water tank 10, and sets the target water temperature of the water tank 10 based on the touch screen. The start-stop module 350 corresponds to a start-stop switch to control start-stop of the heating unit 50.
In some embodiments, the measured water temperature parameter corresponds to the water temperature measured by the first temperature sensor 20, or to the sum of weighted calculations of the water temperatures measured by the first temperature sensor 20 and the second temperature sensor 40.
It will be appreciated that when the reserve power supply is not connected, the first temperature sensor 20 is in an on state and the second temperature sensor 40 is in an off state. At this time, the water temperature inside the water tank 10 is measured only by the first temperature sensor 20, and the measured water temperature parameter is the water temperature measured by the first temperature sensor 20. When the reserve power is connected, both the first temperature sensor 20 and the second temperature sensor 40 are in an on state. At this time, the water temperature inside the water tank 10 is measured by the first temperature sensor 20 and the second temperature sensor 40 together, and the measured water temperature parameter is the sum of the weight calculation values of the water temperatures measured by the first temperature sensor 20 and the second temperature sensor 40.
For example, when both the first temperature sensor 20 and the second temperature sensor 40 are in the on state, the measured water temperature parameter may be an average value of the water temperatures measured by the first temperature sensor 20 and the second temperature sensor 40. I.e., T Measuring water temperature ＝50％*T1+50％*T2(T1 and T 2 are the water temperatures measured by the first temperature sensor 20 and the second temperature sensor 40, respectively). Of course, the measured water temperature parameter may also be the sum of 40% of the water temperature measured by the first temperature sensor 20 and 60% of the water temperature measured by the second temperature sensor 40. I.e. T Measuring water temperature
=40% T 1+60％*T2. Or the measured water temperature parameter may also be the sum of 20% of the water temperature measured by the first temperature sensor 20 and 80% of the water temperature measured by the second temperature sensor 40. I.e., T Measuring water temperature ＝20％*T1+80％*T2. The weights of the measured water temperature parameters corresponding to the first and second temperature sensors 20 and 40 may be specifically adjusted based on the installation positions of the first and second temperature sensors 20 and 40. Wherein the greater the weight of the temperature sensor located at the lower portion, the higher the actual water temperature inside the water tank 10.
For example, when two second temperature sensors 40 are provided, and both the first temperature sensor 20 and the two second temperature sensors 40 are in an on state. The measured water temperature parameter may be an average of water temperatures measured by the first temperature sensor 20 and the two second temperature sensors 40. I.e. T Measuring water temperature ＝1/3(T1+T2+T3)(T1、T2 and T 3 are the water temperatures measured by the first temperature sensor 20 and the two second temperature sensors 40, respectively).
Preferably, when the first temperature sensor 20 and the second temperature sensor 40 are simultaneously in the on state, the measured water temperature parameter is an average value of the water temperatures measured by the first temperature sensor 20 and the second temperature sensor 40. It can be appreciated that the first temperature sensor 20 and the second temperature sensor 40 are equally spaced along the height direction of the water tank 10, and the measured water temperature parameter is obtained by means of average value calculation, so that the measured water temperature parameter is closer to the actual water temperature in the water tank 10.
In some embodiments, the control unit 30 further comprises a calculation module 360, the calculation module 360 being electrically connected to the first temperature sensor 20 and the second temperature sensor 40, the calculation module 360 being configured to calculate a sum of weight calculations of the water temperatures measured by the first temperature sensor 20 and the second temperature sensor 40.
It will be appreciated that the calculation module 360 is a calculation circuit or calculator that calculates based on the measured water temperature fed back by the first and second temperature sensors 20, 40 and derives a measured water temperature parameter.
As shown in fig. 2, in some embodiments, the water heater further includes a display unit 60. The display unit 60 is electrically connected to the calculation module 360, and is used for displaying the measured water temperature parameter. It can be appreciated that the measured water temperature parameter is displayed by the display unit 60, so that the user can know the real-time water temperature, and the water use safety is ensured.
When the second temperature sensor 40 is in the off state, the calculation module 360 does not need to calculate, and the display unit 60 uses the water temperature measured by the first temperature sensor 20 as the measured water temperature parameter and displays the measured water temperature parameter. When the second temperature sensor 40 is in the on state, the display unit 60 displays the sum of the weight calculation values of the water temperatures measured by the first temperature sensor 20 and the second temperature sensor 40. Preferably, the display unit 60 displays an average value of the water temperatures measured by the first temperature sensor 20 and the second temperature sensor 40 when the second temperature sensor 40 is in an on state.
In some embodiments, the display unit 60 also corresponds to the aforementioned touch screen mounted on the surface of the water tank 10, and displays the measured water temperature parameter based on the touch screen.
As shown in fig. 2, in some embodiments, the water heater further includes a third temperature sensor 70. The third temperature sensor 70 is used to measure the ambient temperature outside the water tank 10. The control unit 30 is provided with a temperature threshold, and the switching module 330 is further configured to switch the second temperature sensor 40 based on the comparison between the environmental temperature parameter fed back by the third temperature sensor 70 and the temperature threshold.
The comparator in the control unit 30 can also compare the values of the environmental temperature parameter and the temperature threshold, and feed back the comparison result to the control unit 30, and the control unit 30 makes the switching module 330 control the second temperature sensor 40 to be turned on or off based on the comparison result. For example. When the environmental temperature parameter is greater than or equal to the temperature threshold, the switching module 330 drives the second temperature sensor 40 to be turned on; when the environmental temperature parameter is less than the temperature threshold, the switching module 330 drives the second temperature sensor 40 to be turned off.
The relationship between the ambient temperature and the measured water temperature will be shown below by taking the example of disposing a first temperature sensor 20 and a second temperature sensor 40 in the water tank 10. Wherein, T 1 and T 2 are the water temperatures measured by the first temperature sensor 20 and the second temperature sensor 40, respectively, in units of: DEG C (degrees Celsius). T Ring(s) is the ambient temperature measured by the third temperature sensor 70, in units of: DEG C. It should be noted that, the values of the water temperatures measured by the first temperature sensor 20 and the second temperature sensor 40 are each accurate to the decimal place and the values of the ambient temperatures measured by the third temperature sensor 70 are accurate to the single digit, and the measured water temperature parameter displayed by the display unit 60 is the average value of the water temperatures measured by the two first temperature sensors 20, and the values are accurate to the single digit in a rounded manner.
Table 1, relationship table of ambient temperature, measured water temperature value of first temperature sensor, measured water temperature value of second temperature sensor, and measured water temperature parameter
As shown in table 1, the higher the ambient temperature, the greater the temperature difference between the first temperature sensor 20 and the second temperature sensor 40. It will be appreciated that when the ambient temperature is high, the first temperature sensor 20 and the second temperature sensor 40 need to be turned on simultaneously, so that the average value of the water temperature fed back by the first temperature sensor 20 and the second temperature sensor 40 is used as the measured water temperature parameter to be displayed, so that the measured water temperature parameter is closer to the actual water temperature, and the accuracy of the water temperature is ensured. When the ambient temperature is low, only the first temperature sensor 20 may be required to be turned on, and the water temperature fed back by the first temperature sensor 20 is directly used as a measured water temperature parameter to be displayed.
The deviation of the water temperature values fed back by the first temperature sensor 20 and the second temperature sensor 40, which are distributed at intervals along the height direction of the water tank 10 when the ambient temperature is low, is less, and at this time, the water temperature fed back by the first temperature sensor 20 is also close to the actual water temperature, and the accuracy of the water temperature is also high.
In the present embodiment, the external environment temperature is determined to be in the above-described higher temperature state or lower temperature state based on setting a temperature threshold in the control unit 30. Based on the determination of the state, the on-off of the second temperature sensor 40 is switched. By way of example, the temperature threshold may be set at 0 ℃,10 ℃, and specific values of the temperature threshold are not limited in embodiments of the present application.
The switching module switches on and off at least two first temperature sensors 20 based on whether a reserve power supply is connected and whether the ambient temperature is high or low, so that the water heater at least has the following four operation modes:
Mode one: the environmental temperature measured by the third temperature sensor 70 is less than the temperature threshold, and the detection module 320 detects that there is a reserve power connection (the detection sequence of the environmental temperature and the reserve power connection is not sequential). At this time, the water heater is powered by the reserve power supply, and the commercial power is in a disconnected state. The first temperature sensor 20 is in an on state and the second temperature sensor 40 is in an off state. The water temperature is measured by the first temperature sensor 20, and the measured water temperature is directly displayed as a measured water temperature parameter on the display unit 60. When the water temperature displayed on the display unit 60 reaches the target water temperature parameter, the start-stop module 350 drives the heating unit 50 to be turned off.
Mode two: the environmental temperature measured by the third temperature sensor 70 is less than the temperature threshold, and the detection module 320 detects that the reserve power supply is not connected. At this time, the water heater is supplied with electricity by the utility power. The first temperature sensor 20 is in an on state and the second temperature sensor 40 is in an off state. The water temperature is measured by the first temperature sensor 20, and the measured water temperature is directly displayed as a measured water temperature parameter on the display unit 60. When the water temperature displayed on the display unit 60 reaches the target water temperature parameter, the start-stop module 350 drives the heating unit 50 to be turned off.
Mode three: the environmental temperature measured by the third temperature sensor 70 is greater than or equal to the temperature threshold, and the detection module 320 detects that the reserved power is connected. At this time, the water heater is powered by the reserve power supply, and the commercial power is in a disconnected state. The first temperature sensor 20 and the second temperature sensor 40 are both in an on state, and an average value of the water temperatures measured by the first temperature sensor 20 and the second temperature sensor 40 is displayed as a measured water temperature parameter on the display unit 60. When the water temperature displayed on the display unit 60 reaches the target water temperature parameter, the start-stop module 350 drives the heating unit 50 to be turned off.
Mode four: the environmental temperature measured by the third temperature sensor 70 is greater than or equal to the temperature threshold, and the detection module 320 detects that the reserve power supply is not connected. At this time, the water heater is supplied with electricity by the utility power. The first temperature sensor 20 is in an on state and the second temperature sensor 40 is in an off state. The water temperature is measured by the first temperature sensor 20, and the measured water temperature is directly displayed as a measured water temperature parameter on the display unit 60. When the water temperature displayed on the display unit 60 reaches the target water temperature parameter, the start-stop module 350 drives the heating unit 50 to be turned off.
In some embodiments, the first temperature sensor 20 is located at a middle position of the water tank 10, and the second temperature sensor 40 is located at a lower position of the water tank 10. It will be appreciated that the value of the water temperature measured by the second temperature sensor 40 is less than the value of the water temperature measured by the first temperature sensor 20. Based on the weight calculation, the measured water temperature parameter displayed by the display unit 60 is made closer to the actual water temperature inside the water tank 10.
The measured water temperature parameter is obtained based on the mean value calculation so as to be closer to the actual water temperature inside the water tank 10. Avoiding that the temperature of the water inside the water tank 10 is measured by only the second temperature sensor 40, which results in that the heating unit 50 is not easily stopped up to the temperature or is not up to Wen Tingji. Thus reducing power consumption and reducing the load on the heating unit 50. The phenomenon that the actual water temperature cannot meet the user requirement due to the fact that the heating unit 50 stops in advance when the water temperature in the water tank 10 is measured only by the first temperature sensor 20 is avoided.
As shown in fig. 1, the water tank 10 is constructed with a water inlet 110 at a lower portion thereof, and a water outlet 120 at an upper portion thereof. It will be appreciated that the temperature of the water measured by the first temperature sensor 20 at the middle position of the water tank 10 is closer to the actual temperature of the water inside the water tank 10 than the temperature of the water measured by the second temperature sensor 40 at the lower position due to the stratification caused by the inflow of water from the lower portion of the water heater and the weight of the hot water and the cold water in the water tank 10. Therefore, when the reserve power supply is not connected, the water temperature fed back by the first temperature sensor 20 is used as the measured water temperature parameter, so that the measured water temperature parameter is closer to the actual water temperature inside the water tank 10.
In some embodiments, the reserve power source is a free power source. Based on free reserve power, the utility power can be reduced, and the use cost of the user is saved. The second temperature sensor 40 is used when the reserve power supply is connected and the ambient temperature is high, so that the excessive power consumption of the commercial power is avoided, and the heat storage capacity of the water tank 10 can be improved by using the free power supply.
Specifically, the reserve power supply is one or more of a solar power supply, a water energy power supply, a wind energy power supply, a biomass energy power supply, a wave energy power supply, a tidal energy power supply, a marine temperature difference energy power supply and a geothermal energy power supply.
Taking a solar power supply as an example. When the solar panel is configured in the user's home, the commercial power is disconnected after the detection module 320 detects that the solar panel is connected to the reserve power connection module. At the moment, the solar panel is used for supplying power to the water heater, so that the energy is saved, the environment is protected, and the use cost is reduced.
The water heater provided by the embodiment of the application improves the water temperature in the water tank 10, so that the actual water temperature in the water tank 10 is closer to the target water temperature. And the load of the heating unit 50 is reduced, and the service life of the water heater is prolonged.
