Example one

Fig. 1 is a schematic flow chart of a protection method for a water absorption device according to an embodiment of the present invention. The embodiment can be applied to an application scene of protecting a water absorption device for realizing a water inlet function in washing equipment (such as a dishwasher, a feeding bottle cleaning device and the like), and the method can be executed by the protection device of the water absorption device, wherein the device can be a processor (including a microprocessor), an intelligent terminal, a tablet or a PC (personal computer) and the like; in the embodiment of the present application, a protection device of a water absorption device is taken as an execution main body for explanation, and the method specifically includes the following steps:

after the water absorption device of the washing equipment stops working, water in the inner cavity of the water absorption device flows away through the water inlet pipeline under the siphon effect, so that gas enters the inner cavity of the water absorption device; or under the condition that the inside of the water absorption device does not have suction force, water in the cavity inside the water absorption device can gradually run off through the water inlet pipeline, and parts inside the cavity of the water absorption device can be damaged due to the fact that the cavity inside the water absorption device is anhydrous for a long time. To solve this problem, the present embodiment provides an electronic valve in the water inlet pipeline connected to the water inlet of the water absorbing device; when a water inlet instruction is received, the electronic valve is controlled to be opened, so that water flows into the inner cavity of the water absorption device through the water inlet pipeline, and when the detected second water pressure value of the water inlet pipeline is larger than a preset water pressure threshold value, namely the water amount in the water absorption device meets the working condition, the water absorption device is started again, and the water absorption device is prevented from being damaged; when a water inlet stop instruction is received, the electronic valve is controlled to be closed firstly, water in the water inlet pipeline is blocked in the pipeline, and when the detected first water pressure value at the water inlet meets the closing condition of the water absorption device, namely, the water absorption pressure generated between the water absorption device and the electronic valve meets the closing condition, the water absorption device is closed, so that the water body is reserved in an inner cavity of the water absorption device under the action of the water absorption pressure.

S110, when a water inlet instruction is received, controlling an electronic valve arranged in a water inlet pipeline connected with a water inlet of the water absorption device to be opened, and detecting the working state of the electronic valve in real time to obtain working state information.

In an actual application scenario, for realizing a water inlet function, the washing device (e.g., a dishwasher) may call a built-in water suction device to complete the water inlet task, and the water suction device sucks water from a water source to an inner cavity of the washing device through a water inlet pipeline connected with a water inlet of the water suction device. When the water absorption device is started to absorb water, if air is reserved in the inner cavity of the water absorption device, the water absorption function of the water absorption device is disabled or the efficiency is reduced. Fig. 2 is a schematic structural diagram of the washing apparatus of the present embodiment. The washing equipment is internally provided with a water suction device 21 which sucks water from a water source 23 to an inner cavity of the washing equipment through a water inlet pipeline 22 connected with a water inlet of the water suction device, and the water inlet pipeline 22 is also provided with an electromagnetic valve 24. In order to avoid the above situation, the water absorption device is ensured to normally operate to realize the water inlet function of the washing equipment, when the protection device of the water absorption device receives a water inlet instruction sent by the control device of the washing equipment, the electronic valve 24 arranged in the water inlet pipeline connected with the water inlet of the water absorption device is controlled to be opened, so that water flow enters the water inlet pipeline and flows into the inner cavity of the water absorption device through the water inlet pipeline, and the pre-preparation work is realized before the water absorption device is started.

In order to know whether the water inlet pipeline and the inner cavity of the water absorption device are filled with water, the working state information can be obtained by detecting the working state of the electronic valve in real time, and whether the opening condition of the water absorption device is met or not is judged according to the detected working state information, namely the water inlet pipeline and the inner cavity of the water absorption device are filled with water. Optionally, the electronic valve arranged in the water inlet pipeline connected with the water inlet of the water absorption device can be an electromagnetic valve; the water absorption device can be a diaphragm pump or other water absorption pumps with the same function; the protection device of the water absorption device and the control device of the washing equipment can be the same device, namely can be arranged in the same processor, and different functions can be realized through different software programs.

In one implementation example, when the dishwasher is in an operation state, the protection device of the water absorption device acquires a current clock signal of the dishwasher; and if the current clock signal is within a preset water inlet cycle range, generating the water inlet instruction.

In particular, a washing apparatus may involve a plurality of washing steps when performing a washing process, and a water supply operation may be required for each washing step. Therefore, the corresponding water inlet period can be set in advance according to the time node and the water inlet duration of the water inlet function needing to be started in each washing process. When the washing equipment (such as a dishwasher) is in an execution state of any washing process, the protection device of the water absorption device can acquire the current clock signal of the washing equipment at regular time and acquire the water inlet period information corresponding to the washing process executed by the current washing equipment; and judging whether the current clock signal is in the water inlet period range or not according to the acquired current clock signal and the water inlet period information. If the current clock signal is in the preset water inlet period range, the water inlet function needs to be started, and a water inlet instruction is generated by a protection device of the water absorption device so as to control the electronic valve and the water absorption device to be started. And if the current clock signal is not in the preset water inlet period range, the water inlet function does not need to be started currently. In detail, the clock signal is timed from the beginning of the washing process executed by the washing apparatus, and is cleared after the washing apparatus completes the washing process.

In another embodiment, the washing device may further be communicatively connected to a client of the user, and the client may be capable of controlling a washing process of the washing device through an application program in the client, such as scheduling of the washing process, water intake control, water drainage control, and the like. When the protection device of the water absorption device receives a water inlet control command sent by a user through a client, the protection device of the water absorption device generates a water inlet instruction according to information such as water inlet function starting time, water inlet duration and the like included in the water inlet control command so as to execute water inlet operation. And the outside of the washing equipment is also provided with a control panel, and the water inlet control can be carried out by the operation of a client on the control panel. Specifically, the protection device of the water absorption device receives a key signal sent by the control panel, and determines control information corresponding to the received key signal according to the control information mapping table, so that a corresponding control instruction is generated according to the control information; and if the control information is water inlet operation, generating a water inlet instruction, thereby realizing the control of the water inlet function of the washing equipment.

S120, if the detected working state information meets the starting condition of the water absorption device, starting the water absorption device to conduct a water path between the water inlet and the water outlet of the water absorption device; the water pressure threshold value is the water pressure value when the inner cavity of the water absorption device and the water inlet pipeline are filled with water.

After the electronic valve is controlled to be opened, in order to know whether the water inlet pipeline and the inner cavity of the water absorption device are filled with water or not, the working state of the electronic valve is detected in real time to obtain working state information, and whether the opening condition of the water absorption device is met or not is judged according to the detected working state information, namely the water inlet pipeline and the inner cavity of the water absorption device are filled with water. When the detected working state information at a certain moment does not meet the opening condition of the water absorption device, the situation that a small amount of air is still reserved in the inner cavity of the water absorption device and is not discharged is indicated, and the water absorption device needs to continue waiting. When the working state information detected at a certain moment meets the opening condition of the water absorption device, the fact that the inner cavity and the water inlet pipeline of the water absorption device are filled with water at the moment is shown, the water quantity meeting the working condition is arranged inside the water absorption device, and the air stored in the inner cavity of the water absorption device is exhausted, the water absorption device is controlled to be started by the protection device of the water absorption device, so that the water absorption efficiency of the water absorption device is improved, and the water absorption device is prevented from being damaged.

In one embodiment, the operating state information obtained by detecting the operating state of the electronic valve in real time may be an opening time of the electronic valve. Specifically, the opening time of the electronic valve can be recorded after the electronic valve is opened by means of a clock signal or a pulse signal. The specific process of determining whether the opening condition of the water absorption device is satisfied according to the detected operating state information may be: and the protection device of the water absorption device receives the opening time of the electronic valve detected in real time. And the protection device of the water absorption device judges whether the opening time detected in real time is greater than a preset time threshold value. Specifically, the preset time threshold is the opening duration of the electronic valve when the water inlet pipeline and the internal cavity of the water absorption device are filled with water. When the opening time detected at a certain moment is less than or equal to the preset time threshold, it indicates that a small amount of air still remains in the inner cavity of the water absorption device and is not discharged, and the water absorption device needs to continue waiting. When the opening time detected at a certain moment is greater than the preset time threshold, the fact that the inner cavity and the water inlet pipeline of the water absorption device are filled with water is indicated, the water quantity meeting working conditions is arranged inside the water absorption device, and air stored in the inner cavity of the water absorption device is exhausted, the water absorption device is controlled to be started by the protection device of the water absorption device, so that the water absorption efficiency of the water absorption device is improved, and the water absorption device is prevented from being damaged.

In another embodiment, the working state information obtained by detecting the working state of the electronic valve in real time may be a second water pressure value of the water inlet pipeline where the electronic valve is located. In order to know whether the water inlet pipeline and the inner cavity of the water absorption device are filled with water, a second water pressure value in the water inlet pipeline can be detected in real time by arranging a water pressure sensor in the water inlet pipeline. Specifically, the water pressure sensor is in communication connection with the water absorption device protection device and sends the detected signal containing the second water pressure value to the water absorption device protection device.

And the protection device of the water absorption device receives the second water pressure value of the water inlet pipeline detected in real time. And the protection device of the water absorption device judges whether the second water pressure value detected in real time exceeds a preset water pressure threshold value. Specifically, the preset water pressure threshold value is a water pressure value when the inner cavity of the water absorption device and the water inlet pipeline are filled with water; the water pressure value when the inner cavity of the water absorption device and the water inlet pipeline are filled with water can be obtained by calculation according to the volume of the inner cavity of the water absorption device and the volume of the water inlet pipeline. When the second water pressure value of the water inlet pipeline detected at a certain moment is smaller than or equal to the preset water pressure threshold value, it is indicated that a small amount of air still remains in the inner cavity of the water absorption device and is not discharged, and the water absorption device needs to continue waiting. When the second water pressure value of the water inlet pipeline detected at a certain moment is larger than the preset water pressure threshold value, the fact that the inner cavity of the water absorbing device and the water inlet pipeline are filled with water is indicated, the water amount meeting working conditions is arranged inside the water absorbing device, air reserved in the inner cavity of the water absorbing device is exhausted, and the water absorbing device is controlled to be started by the protection device of the water absorbing device, so that the water absorbing efficiency of the water absorbing device is improved, and the water absorbing device is prevented from being damaged.

In an implementable manner, the protection device of the water suction device may establish the second water pressure value calculation model of the water inlet pipeline according to the internal cavity volume of the water suction device, the volume of the water inlet pipeline and the collected water inlet flow rate of the water inlet pipeline per unit time. After the electronic valve is opened, the time consumption required when the second water pressure value of the water inlet pipeline is greater than the preset water pressure threshold value can be calculated according to the second water pressure value calculation model; and acquiring the actual opening time of the electronic valve, and when the actual opening time of the electronic valve is equal to the calculated consumed time, indicating that the second water pressure value of the water inlet pipeline is greater than the preset water pressure threshold value, and controlling the water absorption device to be opened by the protection device of the water absorption device. Thereby ensure that the inside of water absorption device has the water yield that satisfies operating condition and the air that remains in the water absorption device inner chamber has discharged, improve water absorption device's water absorption efficiency, avoid causing the damage to water absorption device.

In another embodiment, since the water absorption device needs to consume a part of time to perform preparation work such as activation of the motor and operation of parts inside the water absorption device in the early stage of starting, the water absorption device can enter a stable working state to absorb the water in the water inlet pipeline after the preparation work is completed. When the protection device of the water absorption device detects that the second water pressure value of the water inlet pipeline is larger than the preset water pressure threshold value, the water absorption device is started, so that the water absorption device consumes a part of time in the preparation work of the water absorption device, the water absorption work cannot be executed immediately, and the washing equipment has time delay when the water inlet function is realized. In order to improve the water inlet efficiency of the washing device (such as a dishwasher), if the detected second water pressure value is greater than a preset water pressure threshold value, the specific step of activating the water absorbing device may include steps 11 to 14:

step 11, acquiring the water inlet flow of the water inlet pipeline in unit time;

the size of the pipe mouth of the water inlet pipe and the water pressure of the supplied water source influence the water inlet flow of the water inlet pipe per unit time. Under the condition that the electronic valve is opened and the water absorption device is closed, the water inflow rate of the water inlet pipeline in unit time can be detected through the water flow meter. In order to calculate the consumed time required when the second water pressure value of the water inlet pipeline is greater than the preset water pressure threshold value, the protection device of the water absorption device obtains the detected water inlet flow of the water inlet pipeline of the washing equipment in unit time.

Step 12, calculating a difference value between a first initial water pressure value corresponding to the water inlet pipeline detected at the opening moment of the electronic valve and the water pressure threshold value, and calculating the waiting time required by the second water pressure value to reach the water pressure threshold value according to the difference value and the water inlet flow;

the protection device of the water absorption device obtains a first initial water pressure value corresponding to the water inlet pipeline detected at the opening moment of the electronic valve, calculates a difference value between the first initial water pressure value corresponding to the water inlet pipeline and a preset water pressure threshold value, and calculates the waiting time required when a second water pressure value of the water inlet pipeline reaches the water pressure threshold value according to the water pressure difference value obtained through calculation and the obtained water inlet flow meter in unit time. The waiting time required when the second water pressure value of the water inlet pipeline reaches the water pressure threshold value is calculated according to the first initial water pressure value corresponding to the water inlet pipeline detected at the opening moment of the electronic valve, so that the waiting time required when the first water pressure reaches the water pressure threshold value is quickly calculated at the opening moment of the electronic valve.

Step 13, acquiring the starting consumed time corresponding to the water absorption device, and obtaining the pre-starting time according to the starting consumed time and the waiting time;

the protector of the water absorption device can obtain the time consumed for the pre-measured starting of the water absorption device to carry out preparation work such as motor activation, part running inside the water absorption device and the like in the early stage of starting. After the start time consumed by the water absorption device is obtained, the calculated waiting time required for the first water pressure to reach the water pressure threshold value is subtracted from the start time consumed by the water absorption device to obtain the pre-start time, so that the start time consumed by the water absorption device is included in the required waiting time, and the water absorption device can be immediately started to realize the water absorption function without additionally adding the start time consumed by the water absorption device when the second water pressure value of the water inlet pipeline is greater than the preset water pressure threshold value.

In detail, the protection device of the water absorption device can calculate the time required for the running power of the water absorption device to reach the rated power (namely the optimal working state) after the water absorption device is started, namely the starting time, by acquiring the starting current and voltage values of the water absorption device and the rotating speed information of the water absorption device. When parts of the inner cavity of the water absorption device rotate (for example, an impeller rotates), friction is generated between the parts and water in the inner cavity to consume a part of power of the water absorption device, and then the actual operation power after the water absorption device is started is the sum of the effective power of the water absorption device and the loss power in the water absorption device, and a specific calculation formula can be as follows:

wherein, I is the starting current of the water absorption device; u is the starting voltage value of the water absorption device; n is the rotating speed of the parts in the inner cavity of the water absorption device; r is a frictional resistance parameter between a part of the inner cavity of the water absorption device and water; and P is the actual running power of the water absorption device after the water absorption device is started. The starting time t can be obtained when p (t) reaches the rated power (i.e. the optimal working state).

Because each user's installation environment is different among the practical application for the water intake of water absorption device and the water inlet area of the inlet channel that the water source is connected can change, the water pressure that the water source provided and the difference in height between the water inlet of inlet channel and the delivery port of water absorption device all can change, and the change of above-mentioned numerical value can lead to water absorption device's operating power to change, thereby it is consuming time to change the required start-up of water absorption device. Specifically, the operating power of the water absorption device is also related to the inflow Q and the lift H, and the calculation formula is as follows: p (t) QgH/(3.6 η); wherein Q is the water flow in the water inlet pipeline; g is a gravity parameter; h is the lift; eta is the efficiency. The size and the installation environment of lift H, the water pressure that water intake and the water inlet pipeline's that the water source is connected water inlet area, water source provided of water absorption device and the difference in height between the water inlet of inlet channel and water absorption device's the delivery port are relevant, and specific computational formula is: h ═ P2-P1)/ρ g + (v)²2-v²1) 2g + (z2-z 1); wherein, P1 is the water pressure value provided by the water source; p2 is the water pressure value of the water inlet of the water absorption device; v1 is water absorption deviceThe water inlet of the water pump is connected with the water flow of the water inlet pipeline connected with the water source; v2 is the water flow rate at the water inlet of the water absorbing device; z1 is the height of the water inlet pipeline relative to the ground; z2 is the height of the water outlet of the water absorption device relative to the ground.

Therefore, the relation between the head H and the rotating speed n of the part in the inner cavity of the water absorption device is integrated by the formula

Then

The user can shorten the starting time of the water absorption device by properly pressurizing the water pressure provided by the water source or reducing the height difference between the water inlet of the water inlet pipeline and the water outlet of the water absorption device, thereby further improving the water inlet speed.

And 14, acquiring the actual opening time of the electronic valve, and starting the water absorption device if the actual opening time is greater than or equal to the pre-starting time.

The method comprises the steps that after the protection device of the water absorption device obtains the pre-starting time, the actual opening time of the electronic valve is obtained, when the actual opening time of the electronic valve is larger than or equal to the calculated pre-starting time, it is indicated that the pre-starting time of the water absorption device is reached, the protection device of the water absorption device controls the water absorption device to be opened, so that water flow is filled in an inner cavity of the water absorption device through a water inlet pipeline, the starting preparation work of the water absorption device is synchronously carried out, and the second water pressure value of the water inlet pipeline is larger than the preset water pressure threshold value when the starting preparation work of the water absorption device is completed.

In the embodiment of the application, the starting time consumption of the water absorption device is contained in the required waiting time, so that the water absorption function can be immediately started without additionally adding the starting time consumption of the water absorption device when the second water pressure value of the water inlet pipeline is greater than the preset water pressure threshold value, and the water inlet efficiency of the washing equipment (such as a dishwasher) is improved.

S130, when a water inlet stopping instruction is received, the electronic valve is controlled to be closed, and a first water pressure value at the water inlet of the water absorption device is detected in real time.

In practical application scenarios, the washing device (such as a dishwasher) stops water inflow by turning off the water absorption device. Because the inside suction that does not possess of water absorption device, the water in the inside cavity of water absorption device can run off gradually through the inlet channel. In order to avoid the damage of internal components of the water absorbing device caused by the flowing water of the water body in the internal cavity of the water absorbing device, when a water inlet stopping instruction is received, the protection device of the water absorbing device controls the electronic valve to be closed, and the water in the water inlet pipeline is blocked in the water inlet pipeline; detecting a first water pressure value at a water inlet of the water absorption device in real time; because the water absorption device is still in a working state at the moment, water absorption pressure is generated between the water absorption device and the electronic valve. In order to know whether the water absorption pressure generated between the water absorption device and the electronic valve reaches the standard of water retention in the inner cavity of the water absorption device, a first water pressure value at the water inlet can be detected in real time by arranging a water pressure sensor at the water inlet of the water absorption device. Specifically, the water pressure sensor is in communication connection with the water absorption device protection device and sends the detected signal containing the first water pressure value to the water absorption device protection device. Alternatively, the protection device of the water absorption device and the control device of the washing equipment can be the same device.

In one implementation example, the protection device of the water absorption device acquires water level information detected by a sensor arranged inside the dishwasher in real time; and if the water level information reaches the preset water level, generating the water inlet stop instruction.

In particular, a washing apparatus may involve a plurality of washing steps when performing a washing process, and the amount of water required for each washing step may be different. Therefore, the preset water level corresponding to each cleaning step can be set in advance according to the water amount required by each cleaning step. When the washing equipment (such as a dishwasher) is in an execution state of any washing step, the protection device of the water absorption device can acquire water level information detected by a sensor arranged in the dishwasher in real time and acquire a preset water level corresponding to the washing step executed by the current washing equipment; and judging whether the current water level information reaches the acquired preset water level. And if the water level information reaches the acquired preset water level, the water inflow needs to be stopped, and a protection device of the water absorption device generates a water inflow stop instruction so as to control the electronic valve and the water absorption device to be closed.

Of course, the water inlet instruction generating method is only an example, and when the embodiment of the present invention is implemented, the water inlet stop instruction may be directly generated by receiving a water inlet stop control command sent by a user by operating a control panel of the washing device or an application program in a client according to an actual situation, which is not limited in this embodiment of the present invention.

S140, if the detected first water pressure value meets the closing condition of the water absorption device, closing the water absorption device so as to enable the water body to be reserved in the water absorption device.

After the electronic valve is controlled to be opened, in order to know that the water suction pressure generated between the water suction device and the electronic valve meets the closing condition, a first water pressure value at the water inlet can be detected in real time by arranging a water pressure sensor at the water inlet of the water suction device, and a protection device of the water suction device receives the first water pressure value detected in real time. The protection device of the water absorption device judges whether the first water pressure value detected in real time meets the closing condition of the water absorption device. Specifically, the closing condition of the water absorbing device is set according to the standard that the water absorbing pressure generated between the water absorbing device and the electronic valve reaches the standard of retaining water in the inner cavity of the water absorbing device.

When the preset water pressure threshold value of the first water pressure value at the water inlet detected at a certain moment does not meet the closing condition of the water absorption device, the fact that the water absorption pressure generated between the water absorption device and the electronic valve does not meet the closing condition of the water absorption device is indicated, and the waiting is needed. When the first water pressure value of the water inlet detected at a certain moment meets the closing condition of the water absorption device, the water absorption pressure generated between the water absorption device and the electronic valve meets the closing condition, the water body can be remained in the inner cavity of the water absorption device under the action of the water absorption pressure, the protection device of the water absorption device closes the water absorption device at the moment, the water body in the inner cavity of the water absorption device is prevented from gradually losing through the water inlet pipeline, and the water absorption device is protected.

In one embodiment, since the water absorption device needs to consume a part of time to perform preparation works such as motor stall and component swing stop in the water absorption device in the early stage of stopping work, the water absorption device can not completely stop absorbing the water in the water inlet pipeline after the preparation works are completed. When the protection device of the water absorption device detects that the first water pressure value at the water inlet meets the closing condition of the water absorption device, the water absorption device is closed, so that the water absorption device consumes a part of time in the stop preparation work of the water absorption device, and the water absorption work cannot be stopped immediately, and the power consumption of the washing equipment is increased when the water inlet stopping function is realized. In order to achieve an improved rapid stop of water supply to a washing apparatus (e.g. a dishwasher), if the detected first water pressure value satisfies a shut-off condition of the water suction device, the specific steps of shutting off the water suction device may include steps 21 to 24:

step 21, acquiring the current working mode of the water absorption device; each working mode corresponds to a water absorption rate;

the water intake pipeline works in a mode that influences the water absorption rate of the water intake pipeline. Under the condition that the electronic valve is closed and the water absorption device is opened, the current working mode of the water absorption device can be obtained, so that the water absorption rate of the current water absorption device can be calculated according to the current working mode. Specifically, the working mode of the water absorption device comprises information such as working power and working current, and the water absorption rate can be calculated according to the working power, the working current and the specification parameters corresponding to the water absorption device. In order to calculate the time consumption required when the water absorption pressure generated between the water absorption device and the electronic valve meets the closing condition, the protection device of the water absorption device obtains the current working mode of the water absorption device, and therefore the current water absorption rate of the water absorption device is obtained.

Step 22, calculating estimated time consumption required for meeting the closing condition according to the water absorption rate and a second initial water pressure value at the water inlet detected at the closing moment of the electronic valve;

and the protection device of the water absorption device acquires a second initial water pressure value corresponding to the water inlet of the water absorption device detected at the closing moment of the electronic valve, calculates a difference value between the second initial water pressure value corresponding to the water inlet and the water pressure value required by meeting the closing condition, and calculates the estimated consumed time required when the first water pressure value at the water inlet reaches the water pressure value required by the closing condition according to the calculated water pressure difference value and the acquired water absorption rate.

Step 23, obtaining the corresponding closing time of the water absorption device;

the protection device of the water absorption device can obtain the closing time consumption of preparation work of stopping the rotation of the motor, stopping swinging of parts in the water absorption device and the like of the water absorption device in the early stage of closing, which is measured in advance.

And 24, if the estimated consumed time is less than or equal to the closing consumed time, closing the water absorption device.

After the closing time consumption corresponding to the water absorption device is obtained, judging whether the estimated time consumption required by the second water pressure meeting the closing condition is less than or equal to the closing time consumption of the water absorption device or not; and if the estimated consumed time is larger than the closed consumed time, detecting a first water pressure value at the water inlet in real time, and closing the water absorption device when the detected first water pressure value meets the closing condition of the water absorption device. If the estimated time consumption is less than or equal to the closing time consumption, the water absorption device is closed, so that the process that the water absorption pressure generated between the water absorption device and the electronic valve gradually reaches the pressure required by the closing condition and the closing preparation work of the water absorption device are synchronously carried out, the water absorption device is not required to be controlled to be closed after the first water pressure value at the water inlet meets the closing condition, and the first water pressure value at the water inlet meets the closing condition when the closing preparation work of the water absorption device is completed.

In detail, the protection device of the water absorption device can calculate the time required when the internal parts of the water absorption device stop rotating after the water absorption device is closed, namely the closing time, by acquiring the current and voltage values of the water absorption device at the closing time and the rotating speed information of the water absorption device. When parts in the inner cavity of the water absorption device rotate (for example, an impeller rotates), friction is generated between the parts and water in the inner cavity to consume a part of power of the water absorption device, and the running power of the water absorption device at the closing moment is consumed by means of the running friction of the parts in the inner cavity of the water absorption device, and a specific calculation formula can be as follows:

wherein, I is the current value at the closing moment of the water absorption device; u is a voltage value at the closing moment of the water absorption device; n is the rotating speed of the parts in the inner cavity of the water absorption device; r is the friction resistance parameter between the parts of the inner cavity of the water absorption device and water.

Because each user's installation environment is different among the practical application for the water intake of water absorption device and the water inlet area of the inlet channel that the water source is connected can change, the water pressure that the water source provided and the difference in height between the water inlet of inlet channel and the delivery port of water absorption device all can change, and the change of above-mentioned numerical value can lead to water absorption device's operating power to change, thereby it is consuming time to change the required start-up of water absorption device. Specifically, the operating power of the water absorption device is also related to the inflow Q and the lift H, and the calculation formula is as follows: p (t) QgH/(3.6 η); wherein Q is the water flow in the water inlet pipeline; g is a gravity parameter; h is the lift; eta is the efficiency. The size and the installation environment of lift H, the water pressure that water intake and the water inlet pipeline's that the water source is connected water inlet area, water source provided of water absorption device and the difference in height between the water inlet of inlet channel and water absorption device's the delivery port are relevant, and specific computational formula is: h ═ P2-P1)/ρ g + (v)²2-v²1) 2g + (z2-z 1); wherein, P1 is the water pressure value provided by the water source; p2 is the water pressure value of the water inlet of the water absorption device; v1 is the water flow of the water inlet pipeline connecting the water inlet of the water absorbing device and the water source; v2 is the water flow rate at the water inlet of the water absorbing device; z1 is the height of the water inlet pipeline relative to the ground; z2 is the height of the water outlet of the water absorption device relative to the ground.

Then

The user can be through suitably carrying out the pressure boost to the water pressure that the water source provided or reducing the difference in height between the delivery port of the water inlet pipe and the water absorption device to shorten the time consuming of closing of water absorption device to further practice thrift water absorption device's consumption.

In the embodiment of the application, the expected consumed time required by meeting the closing condition of the second water pressure comprises the required closed consumed time of the water suction device when the water suction device is closed, the water suction device can be immediately closed to stop water suction without controlling the water suction device to be closed after the first water pressure value at the water inlet meets the closing condition, and the power consumption of the washing equipment (such as a dishwasher) is reduced.

In one embodiment, the specific process of the protection device of the water absorbing device recognizing that the second water pressure at the water inlet of the water absorbing device satisfies the shut-off condition may include: calculating a target water pressure value according to the volume of the inner cavity of the water absorption device; and if the detected first water pressure value at the water inlet is smaller than or equal to the target water pressure value, identifying that the detected first water pressure value at the water inlet meets the closing condition of the water absorption device.

Specifically, in order to enable the water absorption pressure generated between the water absorption device and the electronic valve to absorb the water body into the inner cavity of the water absorption device, the target water pressure value required for reserving water in the inner cavity of the water absorption device can be obtained through calculation according to the volume of the inner cavity of the water absorption device. And when the detected first water pressure value at the water inlet is smaller than or equal to the calculated target water pressure value, identifying that the detected first water pressure value at the water inlet meets the closing condition of the water suction device.

According to the protection method, the device and the equipment for the water absorption device, provided by the embodiment of the invention, when a water inlet instruction is received, an electronic valve arranged in a water inlet pipeline connected with a water inlet of the water absorption device is controlled to be opened, so that a water body enters the water inlet pipeline; the working state of the electronic valve is detected in real time to obtain working state information, and air remained in the inner cavity of the water absorption device is discharged as water flows into the inner cavity of the water absorption device through the water inlet pipeline; when the detected working state information meets the starting condition of the water absorption device, the water amount meeting the working condition is arranged in the water absorption device, and the air remained in the inner cavity of the water absorption device is exhausted, so that the water absorption efficiency of the water absorption device is improved, and the water absorption device is prevented from being damaged. And starting the water absorption device at the moment to conduct a water path between the water inlet and the water outlet of the water absorption device, so as to realize a water inlet function. When a water inlet stopping instruction is received, controlling the electronic valve to be closed, and blocking water in the water inlet pipeline in the pipeline; detecting a first water pressure value at a water inlet of the water absorption device in real time; because the water absorption device is still in a working state at the moment, water absorption pressure is generated between the water absorption device and the electronic valve; when the first water pressure value of the detected water inlet meets the closing condition of the water absorption device, namely the water absorption pressure generated between the water absorption device and the electronic valve meets the closing condition, the water absorption device is closed, so that the water body is remained in the inner cavity of the water absorption device under the action of the water absorption pressure, the water body in the inner cavity of the water absorption device is prevented from gradually losing through the water inlet pipeline, and the water absorption device is protected.
