Description
P128023NL00 Title: Intellligent household water dispenser
FIELD OF THE INVENTION The invention relates to the field of intelligent household, in particular to an intelligent household water dispenser.
BACKGROUND OF THE INVENTION At present, the household water dispenser is a device for heating barreled purified water or mineral water for people to drink. Barreled water 1s placed above the machine, the water dispenser is matched with a water storage tank for use, and the water storage tank is used for containing purified water or mineral water. The water dispenser commonly used at home is a warm water dispenser. A hot water tank and three water outlet pipes are arranged in the water dispenser, wherein one water outlet pipe is used for communicating the hot water tank and the water reserve tank, one water outlet pipe is used for communicating the hot water tank and the hot water valve for hot water dispensing, and the other water outlet pipe is used for communicating the water storage tank and the cold water valve for cold water dispensing. The water dispenser is provided with a heating indicator and a heat preservation indicator. When the water dispenser is used, a starting switch 1s pressed down, the water dispenser starts to heat water in the hot water tank, and a power supply supplies power to the heating indicator to provide a power-on indication. When the water in the hot water tank is heated to a set temperature, heating is cut off, meanwhile, a heating indicator light is turned off, and a heat preservation indicator light is turned on. When the water temperature drops to the set temperature, the "heating" function 1s activated again, so that the water temperature is maintained between 85 °C-95 °C through cycles. However, in the current household water dispenser, water with preset temperature and preset volume cannot be selected. If we want to drink water with the desired temperature and volume, cold water and hot water need to be repeatedly mixed, but the time and the water amount are not easy to master. Therefore, it is possible that the mixed water can not reach the desired temperature for many times, the operation is troublesome, or the mixed water is too hot to scald the mouth easily, and the mouth feel is affected too cold.
SUMMARY OF THE INVENTION The invention provides an intelligent household water dispenser to solve the problem that in the current household water dispenser water with preset temperature and preset volume cannot be selected. The embodiment of the application shows an intelligent household water dispenser, which comprises: a water reserve tank, a first water outlet at a bottom end of the water reserve tank being communicated with a hot water tank through a first water pipe and being used for supplying water to the hot water tank; a second water outlet at the bottom end being communicated with a water storage tank through a second water pipe and being used for supplying water to the water storage tank; a first valve arranged at one end of a third water pipe communicated with the water storage tank; a second valve arranged at one end of the second water pipe communicated with the water storage tank; the hot water tank being communicated with the water storage tank through the third water pipe and being used for supplying water to the water storage tank when the first valve is in an open state; the water storage tank being used for mixing hot water output by the hot water tank through the third water pipe and cold water output by the water reserve tank through the second water pipe;

DETAILED DESCRIPTION OF THE EMBODIMENTS The technical solutions in the embodiments of the present invention will be described clearly and completely in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all the embodiments. On the basis of the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention. Example 1: An intelligent household water dispenser comprising:
a water reserve tank 1, a first water outlet 11 at a bottom end of the water reserve tank 1 being communicated with the hot water tank 2 through a first water pipe 13 and being used for supplying water to the hot water tank 2; a second water outlet 12 at the bottom end being communicated with the water storage tank 3 through a second water pipe 14 and being used for supplying water to the water storage tank 3; a first valve 31 arranged at one end of the third water pipe 15 communicated with the water storage tank 3; a second valve 32 arranged at one end of the second water pipe 14 communicated with the water storage tank 3; a hot water tank 2 communicated with the water storage tank 3 through the third water pipe 15 and used for supplying water to the water storage tank 3 when the first valve 31 is in an open state; a water storage tank 3 used for mixing hot water output by the hot water tank 2 through the third water pipe 15 and cold water output by the water reserve tank 1 through the second water pipe 14; control panel 4 used for sending a control command; a processor 5 electrically connected with the control panel 4 and used for identifying a received control command; a first control command being responsive to the control command and being used to output a first control signal through a first port 51 to the first valve 31, the first control signal being used to control opening or closing of the first valve 31; a second control command being responsive to the control command and being used to output a second control signal through a second port 52 to the second valve 32, the second control signal being used to control opening or closing of the second valve 32.
The current household water dispenser does not have a control panel, only two display lights of a heating 46 and a heat preservation 47 and two water taps are arranged on the water dispenser body, so that the water flow mainly flows out in two directions, including direction one: cold water (room temperature water) directly flows out of the cold water pipe; direction two: the water flows out of the hot water pipe after being heated. The disadvantage of the water dispenser is that we do not know how much the water temperature is. If we want to receive water at a certain temperature, we can only check it for many times. Not only time is wasted, but also the final temperature may not be what we want. From this end, we set up the control panel 4. The control panel 4 is used to issue control commands to the processor 5. When receiving water, firstly desired temperature and volume are selected on the control panel 4, wherein a temperature option button 41 provides a preset temperature. For example, five temperature option buttons of 100 °C, 80 °C, 60 °C, 40 °C and room temperature are currently set. The temperature option can be set according to the temperature required by a user, and the temperature value corresponding to the temperature option button 41 is the preset temperature, as a second temperature value. The temperature display light 42 is divided into a lighting state and a non-lighting state. When the temperature display light 42 1s in the lighting state, the corresponding temperature value in the temperature option button 41 is selectable, and when the temperature display light 42 is in the non-lighting state, the corresponding temperature value m the temperature option button 41 is not selectable. The volume option 43 provides a preset volume. For example, five volume option buttons currently of 100 ml, 200 ml, 300 ml, 400 ml and 500 ml are set, and the volume options can also be set at will according to the user's needs.
After the preset temperature and the preset volume are selected, water can be discharged by pressing the water outlet/stop button 44. If the button is pressed once in the whole water receiving process, it is defaulted that all water flows out, and no water remains in the water storage tank 3; and if the button is pressed twice in the whole process, the water outlet is stopped at the second time, and the water remains in the water storage tank 3.
Compared with the current household water dispenser, the intelligent household water dispenser provided by the invention has the advantages that the temperature option button 41 and the volume option 43 can be selected on the control panel 4, and the preset temperature and the preset volume are selected on the control panel 4. The control panel 4 sends a control command to the processor 5, while the processor 5 receives and identifies which valve the command specifically relates to. If the first valve 31 is involved, then the processor 5 outputs a first control signal through the first port 51 to control the opening and closing of the first valve 31; if the second valve 32 is involved, the processor 5 outputs a second control signal through a second port 52 to control the opening and closing of the second valve 32, resulting in a preset temperature and a preset volume of water.
Example 2: the water dispenser further comprises a first temperature monitor 21 arranged on a surface of the hot water tank 2 and used for monitoring a first temperature value in the hot water tank 2, and being electrically connected with the processor 5 for outputting a first temperature value.
As shown in FIG. 2, the control panel 4 is provided with a temperature display frame 45 for displaying the real-time temperature of the hot water in the hot water tank 2. On the one hand, a receiver 1s able to know the current water temperature, and on the other hand, a basis is provided for selecting a preset temperature. For example, if the water receiver wants to receive water of 80 °C, but finds that the current water temperature is only 60 °C, the preset water temperature higher than 60 °C in the temperature option buttons 41 is not selectable. For example, the key is gray, and the light of the temperature option button 41 corresponding to the temperature display light 42 is not lit. Pressing the temperature key above 60 °C in the temperature option buttons 41 will not send any control commands and will only be operable after the temperature is heated to 80 °C.
Example 3: the control command carries a second temperature value and a volume value; the processor 5 1s also used for reading the second temperature value and the volume value carried by the control command, and sending a first start command to the first valve 31 in response to the second temperature value being equal to the first temperature value; reading a first preset time corresponding to the volume value in a prestored database, wherein the first preset time is an opening time of the first valve 31; A first closing command is sent to the first valve 31 at an interval of a first preset time.
As shown in FIGs. 1 and 2, after a preset temperature (i.e. a second temperature value) and a preset volume are selected on the control panel 4, the control panel 4 sends a control command to a processor 5. The processor 5 reads the magnitude of the second temperature value and the volume value, and calls different pre-stored databases according to different temperature values and volume values, wherein the pre-stored databases comprise data arrays of a temperature value, a volume value, a hot water flow rate, the first valve 31 (hot water valve) opening duration, a cold water flow rate, and a second valve 32 (cold water valve) opening duration. After the pre-stored data are acquired by the processor 5, a first control signal is output to the first valve 31 through the first port 51 of the processor 5, the opening or closing of the first valve 31 is controlled. A second control signal is sent to the second valve 32 through the second port 52 of the processor 5, and the second control signal is used for controlling the opening or closing of the second valve 32. In the case of this embodiment, the second temperature value is equal to the first temperature value, and the processor 5 is only required to control the opening of the first valve 31 to direct the flow of water from the hot water tank 2 to the water storage tank
3. The first temperature value, 1.e. the temperature value of the water in the hot water tank 2, is for example 60 °C, the preset temperature, i.e. the second temperature value, is also selected to be 60 °C, and the value of volume 1s selected to be 300 ml, at which point the control panel 4 will send a command to the processor 5 to obtain "300 ml, 60 °C of water”. The processor 5 immediately searches the pre-stored database for data. The comparison shows that the second temperature value is equal to the first temperature value, the temperature value 1s 60 °C, and the volume number is 300ml. Temperature | Volume | Flow rate | Hot water | Flow rate | Cold water value (°C) value required valve required valve (ml) for hot opening for cold opening water duration water duration
EEE EEE 60 | 30 | 30 | 0m | 0 | 0 | Table 1 Ti in Table 1 is the result obtained by a large number of experimental data tests, i.e. the time during which a volume of 300 ml of water in the hot water tank 2 is totally circulated through the first water pipe 13 to the water storage tank 3 with the first valve 31 open. As can be seen from Table 1, the first preset time in the prestored database is T:; seconds, and the first valve 31 is closed after an interval of Ty seconds to obtain 300 ml of water at 60 °C. When the second temperature value is equal to the first temperature value, the processor 5 issues a command to open only the first valve. Example 4: The control command carries a second temperature value and a volume value. The processor 5 is also used for reading the second temperature value and the volume value carried by the control command, sending a first start command to the first valve 31 and sending a second start command to the second valve 32 in response to the second temperature value being smaller than the first temperature value; reading a second preset time and a third preset time respectively corresponding to the second temperature and the volume value in a prestored database, wherein the second preset time is an opening time of the first valve 31, and the third preset time is an opening time of the second valve 32; sending a first closing command to the first valve 31 at an interval of the second preset time; and sending a second closing command to the second valve 32 at an interval of the third preset time.
As shown in Figs. 1 and 2, the present example differs from Example 3 in that the present example is directed to a case where the second temperature value is smaller than the first temperature value, at which point both the first valve 31 and the second valve 32 are to be opened, and the processor 5 controls the opening and closing of the first valve 31 and the second valve 32 by retrieving a data arrays pre-stored in a pre-stored database.
For example, if the water receiver wants water at 40 °C, i.e. the preset temperature is 40 °C and the current first temperature, i.e. the temperature in the hot water tank 2, is 75 °C, the required water at 40 °C must be obtained by mixing hot water with cold water, i.e. both the first valve 31 and the second valve 32 should be opened. The preset temperature is selected at 40 °C, and the preset volume 1s selected at 200 ml. a command of acquiring 200ml of water at 40 °C is sent to a processor 5 by the control panel 4 after setting on the control panel 4 is completed. Data in a prestored database is searched by the processor 5 immediately, and it is found out that a data table 2 corresponding to the preset temperature of 40
°C and the volume of 200 ml is as follows: Temperature | Volume | Flow rate | Hot water | Flow rate | Cold water value (°C) value required valve required valve (ml) for hot opening for cold opening water duration water duration
EEE EEE T: Table 2 Fin the Table 2 is a hot water flow value required for obtaining 200 ml of water at 40 °C, the processor 5 sends a first start command to the first valve 31, the valve is opened, and the water flowing into the water storage tank 3 from the hot water tank 2 through the first water pipe 13 is Fi ml.T: is the time duration corresponding to the flow of Fi ml of water to the water storage tank 3 and is a second preset time. After an interval of Ts seconds, the processor 5 sends a first closing command to the first valve 31, and the valve is closed. F> is a cold water flow value required for obtaining 200mlof water at 40 °C, the processor 5 sends a second start command to the second valve 32, the valve is opened, and the water flowing from the water reserve tank 1 to the water storage tank 3 through the second water pipe 14 is Fo ml. T3 is a time duration corresponding to F2 ml of water flowing to the water storage tank 3 and is a third preset time. After an interval of T3 seconds, the processor 5 sends a second closing command to the second valve 32, and the valve is closed. The water storage tank 3 mixes hot water output through the third water pipe (15) with cold water output by the water reserve tank (1) through the second water pipe (14) to finally obtain water with preset temperature and preset volume. Example 5: The processor 5 controls a temperature display light 42 corresponding to the temperature option button 41 of the first temperature zone to be lit in response to the second temperature value being greater than the first temperature value; the first temperature zone is a temperature option key with a corresponding temperature value being less than or equal to the first temperature value in the temperature option buttons 41. In Example 1, the temperature value corresponding to the temperature option button 41 is a preset temperature and serves as a second temperature value; the temperature display light 42 is divided into a lighting state and a non-lighting state. When the temperature display light 42 is in the lighting state, the corresponding temperature value in the temperature option button 41 is selectable, and when the temperature display light 42 is in the non-lighting state, the corresponding temperature value in the temperature option button 41 is not selectable,.
As shown in FIGs. 1 and 2, when the second temperature value is greater than the first temperature value, the preset temperature is greater than the current temperature in the hot water tank. For example, the temperature display frame 45 displays that the current temperature is 50 °C, while the temperature option button 41 corresponds to a temperature value in which a temperature option button (called a second temperature zone) higher than 50 °C is not available, and the temperature display light 42 corresponding to the temperature is in the non-lighting state. After a second temperature zone key is pressed, the control panel 4 will not send any control commands, so that the key is not available. Among the temperature values corresponding to the temperature option button 41, a temperature option key lower than or equal to 50 °C is in a first temperature zone, the temperature option keys of the first temperature zone are selectable, and the temperature display light 42 corresponding to the temperature is lit. After the preset temperature and the preset volume are set, the water outlet/stop button 44 is pressed down. The processor 5 sends a command for controlling the opening of the fourth valve 34, water is discharged through the water outlet 7 at the moment, and water with the preset temperature and the preset volume 1s obtained.
Example 6: In the water dispenser, the control panel 4 further comprise: a temperature display frame 45 arranged on a surface of the control panel 4, electrically connected with the first temperature monitor 21 and used for displaying the first temperature value output by the first temperature monitor 21.
In Example 2, the first temperature monitor 21 is arranged on the surface of the hot water tank 2 and is used for monitoring a first temperature value in the hot water tank 2; the first temperature monitor 21 it is electrically connected with the processor 5 for outputting the first temperature value. It can be seen therefrom that the temperature display frame 45 is used for displaying the current temperature of the water in the hot water tank 2. On the one hand, the water receiver is able to know the current water temperature state, and on the other hand, a basis is provided for whether the temperature option button 41 is available and whether the temperature display light 42 is lit in Example 5.
Example 7: The bottom end of the water storage tank 3 further comprises: a first gravity sensor 8 arranged at the bottom end of the water storage tank 3, electrically connected with the processor 5 and used for measuring a first gravity value of water in the water storage tank 3 and feeding back the first gravity value to the processor 5; a fourth water pipe 16 arranged at bottoms of the hot water tank 2 and the water storage tank 3 and used for circulating water in the water storage tank 3 into the hot water tank 2 when the third valve 33 isin an open state; a water pump 6 which penetrates through the fourth water pipe 16 for providing power when the water in the water storage tank 3 flows into the hot water tank 2.
In Example 1, if the water outlet/stop button 44 is pressed once in the whole water receiving process, it 1s defaulted that water flows out completely, and no water remains in the water storage tank 3; and if the water 1s pressed twice in the whole process, the water outlet 1s stopped at the second time, and the water remains in the water storage tank 3.
When water remains in the water storage tank 3, the temperature and volume of the next water receiving will be affected, so that the remaining water is drained out of the water storage tank in time. As shown in FIG. 3, the first gravity sensor 8 is used for measuring a first weight value of water in the water storage tank 3 and feeding back a measurement result to the processor 5. After water receiving is completed, if water remains in the water storage tank 3, the first weight value measured by the first gravity sensor 8 will not be 0. The processor 5 sends a third start command to the third valve 33 and a fourth start command to the water pump 6 after receiving the result that the weight value is not zero. The water pump 6 draws residual water from the water storage tank 3 into the hot water tank 2 through the fourth water pipe 16 by using the pumping force. The first gravity sensor 8 also feeds back a measurement result to the processor 5 in real time during the water discharge process. When the measured weight value is zero, and the processor 5 sends a third closing command to the third valve 33 and a fourth closing command to the water pump 6 so as to discharge residual water in the water storage tank 3. On one hand, the influence of residual water on the temperature and the volume of the next water receiving is eliminated, and on the other hand, the waste of water is prevented.
Example 8: The water dispenser further comprises: a second gravity sensor 9 arranged at the bottom end of the water reserve tank 1, electrically connected with the processor 5 and used for measuring a second weight value of residual water in the water reserve tank 1 and the water barrel of the water dispenser and feeding back the second weight value to the processor 5. A water change reminder button 48 is arranged on the surface of the control panel 4 and is electrically connected with the processor 5. After the processor 5 receives the weight value measured by the second gravity sensor 9, the weight value is compared with a threshold value, and when the weight value is equal to or smaller than the threshold value, a control command for controlling the flashing of the water change reminder button 481s sent.
At present, people need to check the water of the household water dispenser at any time when the water 1s not available, so that manpower is wasted. Regarding this, the present application provides a second gravity sensor 9 and a water change reminder button 48 to solve the problem that manual checking is required when the water is not available, with reference to FIGs. 2 and 3. Firstly, a threshold value is set, while the threshold value is taken as a dividing line. When the total weight value of residual water in the water reserve tank 1 and the water barrel of the water dispenser is larger than the threshold value, water does not need to be changed, and a water change reminder button 48 does not flash. When the total weight value of residual water in the water reserve tank 1 and the water barrel of the water dispenser is less than or equal to the threshold value, the water change reminder button 48 flashes to remind that water needs to be changed currently.
For example, the threshold value is set to 0.2 kg, the second weight value measured by the second gravity sensor 9 is 0.18 kg, and the measured result is fed back to the processor 5. After the processor 5 receives the measured result, the measured result 0.18 kg is compared with the threshold value. After comparison, the measured result is found to be smaller than the threshold value, a flashing command is sent to the water change reminder button 48, and at the moment, the button flashes to remind of timely water change. A person does not need to check whether water needs to be changed or not at any time and flickering is stopped when the measurement result is larger than the threshold value.
As shown in FIG. 4, the operation flow chart of the intelligent household water dispenser provided by the invention summarizes the overall flow chart of the examples. Through the flow chart, the working principle of the internal structure of the water dispenser in the whole water receiving process 15 more intuitively displayed, and the correlation relationship among the examples is also displayed. The specific workflow comprises the following steps: S1: setting a preset temperature and a preset volume on the control panel 4, and sending a control command by the control panel 4; S2: the processor 5 receiving a command sent by the control panel 4 and identifying information carried by the control command; S3: judging magnitudes of current temperature and the preset temperature in the control panel command; when the preset temperature is higher than the current temperature: the corresponding temperature indicator light higher than the current temperature is not lit, indicating being unavailable and waiting for the water temperature to be heated to the preset temperature or above the preset temperature; when the preset temperature 15 lower than or equal to the current temperature: reading command information, and calling data in a prestored database according to water temperature and volume values in the command; S4: according to a comparison relation between the current temperature and the preset temperature in step S3, the processor 5 sending a control command to control the opening and closing of the first valve and the second valve; and
S5: judging whether the water in the water tank flows out completely.
If residual water exists, the processor 5 triggering a command for starting the water pump, the water pump pumping water, triggering a command for starting the third valve, and fully pumping the residual water back to the hot water tank by usmg the pumping force of the water pump; and if all water outflows with no remain, the processor 5 triggering a water valve closing command, the water valve bemg closed, and water outlet bemg stopped.
The invention provides an intelligent household water dispenser, wherein the bottom end of a water reserve tank 1 is provided with two water outlets, a first water outlet 11 being connected with a hot water tank 2 through a first water pipe 13 to supply water, a second water outlet 12 being connected with a water storage tank 3 through a second water pipe 14 to supply water, and the water storage tank 3 being used for mixing hot water output by the hot water tank 2 through a third water pipe 15 and cold water output by the water reserve tank 1 through a second water pipe 14. A preset temperature and a preset volume are selected on the control panel 4, and a control command is sent to the processor 5 by the control panel 4, a first control command being responsive to the control command and outputting a first control signal to the first valve 31 through a first port 51, wherein the first control signal is used for controlling the opening or closing of the first valve 31, a second control command being responsive to the control command and used for sending a second control signal to the second valve 32 through a second port 52, wherein the second control signal is used for controlling the opening or closing of the second valve 32, so that the preset temperature and the preset volume of water are obtained. In addition, the water dispenser further comprises a first temperature monitor 21 used for displaying the current water temperature in the hot water tank, a first gravity sensor 8 used for measuring a first weight value of water in the water storage tank 3 and feeding back a measurement result to the processor 5, a second gravity sensor 9 and a water change reminder button 48, and the processor 5 sends a control command for controlling the water change reminder button 48 to flash to remind of water change.
