Detailed ways

The following describes the technical solutions in the embodiments of the present invention clearly and completely with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

Example 1:

A smart home drinking fountain, including:

The first water outlet 11 at the bottom of the water storage tank 1 communicates with the hot water tank 2 through a first water pipe 13 for supplying water to the hot water tank 2; 3 is connected to supply water to the water storage tank 3;

The first valve 31 is arranged at one end of the third water pipe 15 that communicates with the water storage tank 3;

The second valve 32 is provided at one end of the second water pipe 14 communicating with the water storage tank 3;

The hot water tank 2 is in communication with the water storage tank 3 through the third water pipe 15, and is used to supply water to the water storage tank 3 when the first valve 31 is in an open state;

The water storage tank 3 is used to mix the hot water output from the hot water tank 2 through the third water pipe 15 and the cold water output from the water storage tank 1 through the second water pipe 14;

The control panel 4 is used to issue control instructions;

The processor 5, electrically connected to the control panel 4, is used to identify the received control command; in response to the control command being the first control command, it is used to output a first control signal to the first valve 31 through its first port 51. A control signal is used to control the opening or closing of the first valve 31; in response to the control command being a second control command, it is used to send a second control signal to the second valve 32 through its second port 52, and the second control signal is used to The opening or closing of the second valve 32 is controlled.

The current domestic water dispenser does not have a control panel. There are only two indicator lights for heating 46 and heat preservation 47 on the water dispenser body, and there are two faucets, so the water flow is mainly divided into two directions. Direction 1: cold water (normal temperature water) directly from cold water The pipe flows out; direction two: the water flows out from the hot water pipe after being heated. The disadvantage of this type of water dispenser is that we don’t know the specific water temperature. If we want to receive a certain temperature of water, we can only blend it multiple times by ourselves. Not only is time wasting, but the final temperature may not be what we want. Based on this, we Set up the control panel 4.

The control panel 4 is used to issue control instructions to the processor 5. When receiving water, first select the desired temperature and volume on the control panel 4. The temperature option button 41 provides preset temperature, for example, there are currently 5 temperature option buttons of 100℃, 80℃, 60℃, 40℃ and normal temperature. , The temperature option can be set according to the temperature required by the user. The temperature value corresponding to the temperature option button 41 is the preset temperature, as the second temperature value; the temperature indicator lamp 42 is divided into two states: on and off, when it is When the temperature option button 41 is lit, the corresponding temperature value in the temperature option button 41 is selectable, and the unlit state is not selectable; the volume option 43 provides a preset volume, such as the current setting of 100ml, 200ml, 300ml, 400ml and 500ml. A volume option button, the volume option can also be set according to user needs.

After the preset temperature and preset volume are selected, press the water outlet/stop button 44 to release water. If this button is pressed only once during the whole process of receiving water, all water will flow out by default, and there is no remaining water in the water storage tank 3; if pressed twice during the whole process, the second time is to stop the water flow, and the water in the water storage tank 3 will be stopped. There is surplus.

The smart home water dispenser provided by this application is compared with the current domestic water dispenser. The temperature option button 41 and the volume option 43 can be selected on the control panel 4, and the preset temperature and preset can be selected on the control panel 4. Volume, the control panel 4 will send a control instruction to the processor 5, the processor 5 receives and recognizes which valve the instruction specifically involves, if the first valve 31 is involved, the processor 5 outputs the first control signal through its first port 51 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 its second port 52 to control the opening and closing of the second valve 32, thereby obtaining the preset temperature and preset Set the volume of water.

Example 2:

The drinking fountain also includes a first temperature monitor 21, which is arranged on the surface of the hot water tank 2 and is used to monitor the first temperature value in the hot water tank 2; and is electrically connected to the processor 5 and used to output the first temperature value.

As shown in Figure 2, a temperature display frame 45 is provided on the control panel 4 to display the real-time temperature of the hot water in the hot water tank 2. On the one hand, the receiver can understand the current water temperature, and on the other hand, it provides a basis for selecting a preset temperature. For example, if the person receiving the water wants to receive water at 80°C, but finds that the current water temperature is only 60°C, then the preset water temperature higher than 60°C in the temperature option button 41 is not selectable. For example, the button is gray, and the temperature indicator light 42 corresponds to it. The light of the temperature option button 41 is also off. After pressing the temperature button higher than 60°C in the temperature option button 41, the processor 5 will not send any control commands, and can only operate after the temperature is heated to 80°C.

Example 3:

The control command carries the second temperature value and the volume value;

The processor 5 is also configured to read the second temperature value and the volume value carried by the control instruction, and in response to the second temperature value being equal to the first temperature value, send the first start instruction to the first valve 31;

Read the first preset time corresponding to the volume value in the pre-stored database, where the first preset time is the opening duration of the first valve 31;

Send a first closing command to the first valve 31 at intervals of a first preset time.

As shown in Figure 1 and Figure 2, after the preset temperature (ie the second temperature value) and the preset volume are selected on the control panel 4, the control panel 4 sends the control instruction to the processor 5, and the processor 5 reads the second The size of temperature value and volume value, according to different temperature value and volume value call different pre-stored database, the pre-stored database includes temperature value, volume value, hot water flow, first valve 31 (hot water valve) open time, cold water Data columns such as flow rate and opening time of the second valve 32 (cold water valve). After the processor 5 obtains the pre-stored data, it outputs a first control signal to the first valve 31 through its first port 51, controls the opening or closing of the first valve 31, and sends a second control signal to the second valve through its second port 52. The valve 32, the second control signal is used to control the opening or closing of the second valve 32. In this embodiment, the second temperature value is equal to the first temperature value, and the processor 5 only needs to control the first valve 31 to open, and the water in the hot water tank 2 is directly circulated to the water storage tank 3. The first temperature value is the temperature of the water in the hot water tank 2, for example 60°C, the preset temperature, that is, the second temperature value, is also selected as 60°C, and the volume is selected as 300ml. At this time, the control panel 4 will report to the processor 5 Sending the command to obtain "300ml, 60℃ water", the processor 5 immediately searches the data in the pre-stored database, and finds that the second temperature value is equal to the first temperature value, the temperature value is 60℃, and the volume is 300ml. Data sheet 1 is:

Table 1

_{T 1 in} Table 1 is the result obtained through a large number of experimental data tests, that is, the 300ml volume of water in the hot water tank 2 is all circulated to the water storage tank 3 through the first water pipe 13 when the first valve 31 is opened. duration. It can be seen from Table 1 that the first preset time in the pre-stored database is T ₁ second, and the _{first valve 31 is closed after an interval of T 1} second 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 an instruction to open only the first valve.

Example 4:

The control instruction carries a second temperature value and a volume value;

The processor 5 is further configured to read the second temperature value and the volume value carried by the control instruction, and send a first start instruction in response to the second temperature value being less than the first temperature value To the first valve 31, send a second start instruction to the second valve 32;

Read the second preset time and the third preset time respectively corresponding to the second temperature and the volume value in the pre-stored database, the second preset time is the opening time of the first valve 31, the first 3. The preset time is the opening time of the second valve 32;

Sending a first closing instruction to the first valve 31 at intervals of the second preset time;

Send a second closing instruction to the second valve 32 at intervals of the third preset time.

As shown in Figures 1 and 2, the difference between this embodiment and Embodiment 3 is that this embodiment is aimed at a situation where the second temperature value is less than the first temperature value. At this time, both the first valve 31 and the second valve 32 are opened. The processor 5 controls the opening and closing of the first valve 31 and the second valve 32 by retrieving the pre-stored data column in the pre-stored database.

For example, if the person receiving the water wants 40°C water, that is, the preset temperature is 40°C, and the current first temperature, that is, the temperature in the hot water tank 2 is 75°C, the person who wants to get 40°C water must have hot water and The cold water is mixed, which means that both the first valve 31 and the second valve 32 must be opened. The preset temperature is 40°C, and the preset volume is 200ml. After setting on the control panel 4, the control panel 4 will send an instruction to the processor 5 to obtain "200ml, 40°C water", and the processor 5 will search the pre-stored database immediately According to the data in the comparison, it is found that the preset temperature is 40°C and the volume is 200ml. The corresponding data table 2 is:

Table 2

_{F 1 in} Table 2 is the hot water flow value required to obtain "200ml, 40°C water", the processor 5 sends the first start command to the first valve 31, the valve opens, and the hot water tank 2 passes through the first water pipe 13 The water flowing into the storage tank 3 is F ₁ ml; T ₂ is the time corresponding to the flow of F ₁ ml water to the storage tank 3, which is the second preset time. After an interval of T ₂ seconds, the processor 5 sends the first When a closing command is given to the first valve 31, the valve is closed.

F ₂ is to obtain the cold water flow value required for "200ml, 40°C water", the processor 5 sends a second start command to the second valve 32, the valve opens, and the water storage tank 1 circulates to the water storage tank 3 through the second water pipe 14 The water in the middle is F ₂ ml; T ₃ is the time corresponding to the flow of the F ₂ ml water to the storage tank 3, which is the third preset time. After an interval of T ₃ seconds, the processor 5 sends the second closing command to the second Valve 32, the valve is closed.

The water storage tank 3 mixes the hot water output through the third water pipe (15) and the cold water output from the water storage tank (1) through the second water pipe (14) to finally obtain water with a preset temperature and a preset volume.

Example 5:

The processor 5, in response to the second temperature value being greater than the first temperature value, controls the temperature indicator lamp 42 corresponding to the temperature option button 41 of the first temperature zone to light up; the first temperature zone corresponds to The temperature value is a temperature option button of the temperature option button 41 that is less than or equal to the first temperature value.

It is mentioned in embodiment 1 that the temperature value corresponding to the temperature option button 41 is the preset temperature, which is used as the second temperature value; the temperature indicator lamp 42 is divided into two states: on and off. The corresponding temperature value in the option button 41 is selectable, and the unlit state is not selectable.

As shown in Figures 1 and 2, when the second temperature value is greater than the first temperature value, that is, the preset temperature is greater than the current temperature in the hot water tank, for example, the temperature display box 45 displays that the current temperature is 50°C, and the temperature option button 41 corresponds to Among the temperature values, the temperature option buttons (called the second temperature zone) higher than 50°C are not available, and the temperature indicator lamp 42 corresponding to the temperature is off. After the second temperature zone button is pressed, the control panel 4 No control commands will be sent, so they are all unavailable. Among the temperature values corresponding to the temperature option button 41, the temperature option button lower than or equal to 50° C. is the first temperature zone, the temperature option buttons in the first temperature zone are all selectable, and the temperature indicator lights 42 corresponding to the temperature are all on. After setting the preset temperature and preset volume, press the water outlet/stop button 44, and the processor 5 sends an instruction to control the opening of the fourth valve 34. At this time, water is discharged through the outlet 7 to obtain the preset temperature and preset volume. Volume of water.

Example 6:

In the water dispenser, the control panel 4 further includes:

The temperature display frame 45 is arranged on the surface of the control panel 4 and is electrically connected to the first temperature monitor 21 for displaying the first temperature value output by the first temperature monitor 21.

As mentioned in Embodiment 2, the first temperature monitor 21 is arranged on the surface of the hot water tank 2 to monitor the first temperature value in the hot water tank 2; it is electrically connected to the processor 5 and is used to output the first temperature value. . It can be seen that the temperature display frame 45 is used to display the current temperature of the water in the hot water tank 2. On the one hand, it allows the water receiver to understand the current water temperature status, and on the other hand, it is whether the temperature option button 41 is available and the temperature display lamp in embodiment 5 is available. 42 whether to light up to provide a basis.

Example 7:

The bottom end of the water storage tank 3 also includes:

The first gravity sensor 8 is arranged at the bottom end of the water storage tank 3, is electrically connected to the processor 5, and is used to measure the first weight value of the water in the water storage tank 3. The weight value is fed back to the processor 5.

The fourth water pipe 16 is arranged at the bottom of the hot water tank 2 and the water storage tank 3, and is used to circulate the water in the water storage tank 3 to the hot water tank 2 when the third valve 33 is in an open state;

The water pump 6 penetrates the fourth water pipe 16 and is used to provide power when the water in the water storage tank 3 flows into the hot water tank 2.

As mentioned in example 1, if the water outlet/stop button 44 is pressed only once during the whole process of receiving water, all water will flow out by default, and there is no water remaining in the water storage tank 3; if pressed twice during the whole process, the second time is to stop. If the water is discharged, the water in the water storage tank 3 has surplus.

When there is water remaining in the water storage tank 3, it will affect the temperature and volume of the next water connection, so the remaining water must be discharged from the water storage tank in time. As shown in Figure 3, the first gravity sensor 8 is used to measure the first weight value of the water in the water storage tank 3 and feedback the measurement result to the processor 5. After the water connection is completed, if there is water remaining in the water storage tank 3, then The first weight value measured by the first gravity sensor 8 will not be zero. After the processor 5 receives the result that is not 0, it sends a third start instruction to the third valve 33 and a fourth start instruction to the water pump 6. The water pump 6 uses the pumping force to pass the remaining water from the storage tank 3 through the fourth water pipe 16 is pumped into the hot water tank 2. When the water is discharged, the first gravity sensor 8 will also feed back the measurement result to the processor 5 in real time. When the measured weight value is 0, the processor 5 sends a third closing instruction to The third valve 33 sends a fourth closing instruction to the water pump 6 so as to discharge the remaining water in the water storage tank 3. On the one hand, the influence of the remaining water on the temperature and volume of the next water connection is eliminated, and on the other hand, the waste of water is prevented.

Example 8:

Drinking fountains also include:

The second gravity sensor 9 is arranged at the bottom end of the water storage tank 1 and is electrically connected to the processor 5 for measuring the second weight value of the remaining water in the water storage tank 1 and the water dispenser bucket, and feedback the second weight value to the processor器5.

The water change reminder button 48 is arranged on the surface of the control panel 4 and is electrically connected to the processor 5. After the processor 5 receives the weight value measured by the second gravity sensor 9, it compares the weight value with the threshold value. When the weight value is When it is equal to or less than the threshold, a control instruction for controlling the flashing of the water change reminder button 48 is sent.

The current domestic water dispenser needs to be checked at any time when the water is running out. This is a waste of manpower. Based on this, this application sets up a second gravity sensor 9 and a water change reminder button 48 to solve the problem of manual checking when the water is running out. , See Figure 2 and Figure 3. First set a threshold, and use the threshold as the dividing line. When the total weight of the remaining water in the water storage tank 1 and the water dispenser bucket is greater than the threshold, there is no need to change the water, and the water change reminder button 48 does not flash; when it is less than or equal to the threshold , The water change reminder button 48 flashes to remind the current water change.

For example, we set the threshold to 0.2㎏, the second weight measured by the second gravity sensor 9 is 0.18kg, and the measured result is fed back to the processor 5. After the processor 5 receives the measurement result, it will This measurement result of 0.18kg is compared with the threshold value. After the comparison, the measurement result is found to be less than the threshold value. Send a flashing instruction to the water change reminder button 48. At this time, the button flashes to remind you to change the water in time. You don’t need to manually check whether the water needs to be changed anytime. If the measurement result is greater than the threshold, the flashing will stop.

As shown in Figure 4, a working flow chart of a smart home water dispenser provided for this application summarizes the overall flow of the above embodiment. Through this flow chart, the working principle of the internal structure of the water dispenser during the entire water receiving process is more intuitively displayed. The association relationship between the various embodiments is also shown. The specific workflow steps are as follows:

S1: Set the preset temperature and preset volume on the control panel 4, and the control panel 4 sends out control commands;

S2: The processor 5 receives the instruction issued by the control panel 4, and recognizes the information carried in the control instruction;

S3: Determine the size of the 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 that is higher than the current temperature is off, indicating that it is unavailable, and it is necessary to wait for the water temperature to be heated to or above the preset temperature;

When the preset temperature is lower than or equal to the current temperature: read the command information, and retrieve the data in the pre-stored database according to the water temperature and capacity value in the command;

S4: According to the comparison between the current temperature and the preset temperature in step S3, the processor 5 issues a control command to control the opening and closing of the first valve and the second valve;

S5: Determine whether all the water in the water tank has flowed out.

If there is surplus, the processor 5 triggers an instruction to turn on the water pump, the pump pumps water, triggers an instruction to open the third valve, and uses the pumping power to pump all the remaining water back to the hot water tank; if all flows out and there is no surplus, the processor 5 The command to close the water valve is triggered, the water valve is closed, and the water is stopped.
