Technical Field

[0001] The present invention relates to the technical field of water purification, and in particular to a pipeline machine, a water purifier, a control method for the pipeline machine, and a control method for the water purifier. Background Art

[0002] With the development of society and the continuous improvement of people's living standards, people's requirements for quality of life are getting higher and higher. The pipeline machine can receive and store the purified water provided by the water purifier so that users can directly drink purified water of suitable temperature at any time.

[0003] The existing pipeline machine and the water purifier connected thereto are only fluidically connected, and they respectively realize their respective functions. A high-pressure switch is usually provided on the water path interconnected with the pipeline machine in the water purifier, and the water purifier uses the detection signal of the high-pressure switch as a control signal for whether to supply water.

[0004] In the above-mentioned water purifier, the pipeline connected to the pipeline machine is always under great pressure, which causes the pipeline to be easily damaged due to water leakage, resulting in a poor user experience. Summary of the invention

[0005] In order to at least partially solve the problems existing in the prior art, some embodiments of the present invention provide a pipeline machine, which has a clean water inlet and a water intake, and includes: a first water storage device, a first water level detection device, a first communication device and a first control module, the water inlet of the first water storage device is connected to the clean water inlet through a first water channel, the first water level detection device is arranged in the first water storage device, and the water outlet of the first water storage device is connected to the water intake; the first control module is electrically connected to the first water level detection device and the first communication device, and the first control module is used to send a control signal to the water purifier via the first communication device according to the water level information in the first water storage device detected by the first water level detection device, so as to control the water supply of the water purifier.

[0006] In the above technical solution, the pipeline machine can detect the water level in the first water storage device and send a corresponding control signal to the water purifier via the first communication device to realize automatic intelligent control of the water purifier. In this way, an intelligent interconnection between the pipeline machine and the water purifier is established, which significantly improves the user experience. In addition, the connecting pipe between the pipeline machine and the water purifier does not need to be under continuous pressure, which reduces the risk of water leakage and increases the service life.

[0007] Exemplarily, the first control module sends a control signal to the water purifier via the first communication device based on the water level information in the first water storage device detected by the first water level detection device, including performing the following operations: when the water level information in the first water storage device indicates that the current water level is lower than the first water level, sending a control signal instructing water extraction.

[0008] In the above technical solution, when the water level in the first water storage device is low, the water purifier is controlled to replenish purified water in time. Thus, the amount of water in the first water storage device of the pipeline machine can be guaranteed, thereby ensuring that the pipeline machine can provide purified water to the user in time.

[0009] Exemplarily, the pipeline machine also includes a water intake detection device, which is arranged at the purified water inlet. The first control module is also electrically connected to the water intake detection device. The first control module is also used to receive a water intake signal from the water intake detection device, wherein the first control module sends a control signal indicating water intake, which is only executed when the first control module receives a water intake signal from the water intake detection device.

[0010] In the above technical solution, the pipeline machine can replenish the first water storage device in time only after the user takes water. In other time periods, there is no need to send a control signal indicating water taking according to the water level information in the first water storage device, which can reduce the power consumption of the pipeline machine and achieve energy saving. In addition, in the event of a leak in the first water storage device of the pipeline machine, the first water storage device will not be replenished unnecessarily, avoiding the waste of purified water.

[0011] Exemplarily, the first control module sends a control signal to the water purifier via the first communication device based on the water level information in the first water storage device detected by the first water level detection device, including performing the following operations: when the water level information in the first water storage device indicates that the current water level is higher than the second water level, sending a control signal instructing to stop drawing water.

[0012] In the above technical solution, when the water level in the first water storage device is high, the water purifier is controlled to stop replenishing the purified water in time. In this way, the replenishment of water can be stopped in time when the first water storage device is nearly full, so as to prevent the purified water in the first water storage device from overflowing or being damaged due to excessive water pressure.

[0013] Exemplarily, the pipeline machine also includes a water inlet solenoid valve, which is arranged on the first water path; the first control module is electrically connected to the water inlet solenoid valve, and the first control module is also used to control the water inlet solenoid valve to open or close according to the water level information in the first water storage device detected by the first water level detection device.

[0014] In the above technical solution, a water inlet solenoid valve is provided in the pipeline machine, which can not only prevent the water in the first water storage device from flowing back, but also effectively avoid the first water storage device from overflowing due to excessive water or being damaged due to excessive water pressure.

[0015] Exemplarily, the first control module is also used to receive a feedback signal from the water purifier via the first communication device, and control the water inlet solenoid valve to close after receiving the feedback signal, wherein the feedback signal indicates that the water level in the second water storage device of the water purifier is lower than the third water level.

[0016] In the above technical solution, the first control module receives the feedback signal that the water purifier cannot supply water via the first communication device, and controls the water inlet solenoid valve to close according to the feedback signal. This can not only prevent the water from the pipeline machine from flowing back to the water purifier, but also give priority to providing purified water to the water purifier when it is connected to a water intake device with a higher priority.

[0017] Some embodiments of the present invention also provide a water purifier having a raw water inlet and a first purified water outlet, the water purifier comprising a water purification module, a second water storage device, a water delivery device, a second communication device and a second control module, the water inlet of the water purification module being connected to the raw water inlet, the water inlet of the second water storage device being connected to the water outlet of the water purification module, the water outlet of the second water storage device being connected to the water inlet of the water delivery device, the water outlet of the water delivery device being connected to the first purified water outlet, the second control module being electrically connected to the second communication device and the water delivery device, the second control module being used to control the water delivery device to open or close according to a control signal from a pipeline machine received via the second communication device, so as to supply water or stop water supply to the pipeline machine, wherein the pipeline machine is connected to the first purified water outlet.

[0018] In the above technical solution, the water purifier can control the water delivery device therein according to the control signal from the pipeline machine, and then control whether to supply water to the pipeline machine. This establishes an intelligent interconnection between the pipeline machine and the water purifier, and can intelligently control the water supply of the water purifier according to the status of the pipeline machine, significantly improving the user experience. In addition, the connecting pipe between the pipeline machine and the water purifier does not need to be under continuous pressure, which reduces the risk of water leakage and increases the service life.

[0019] Exemplarily, the second control module controls the water delivery device to be opened or closed according to a control signal from the pipeline machine received via the second communication device, including performing the following operations: when the control signal indicates water extraction, controlling the water delivery device to be opened.

[0020] In the above technical solution, the second control module is used to control the water delivery device to open according to the control signal from the pipeline machine indicating water intake. In this way, the water purifier can replenish purified water to the pipeline machine in time according to the needs of the pipeline machine, thereby ensuring that the user can smoothly take water from the pipeline machine.

[0021] Exemplarily, the second control module controls the water delivery device to open or close according to a control signal from the pipeline machine received via the second communication device, including performing the following operations: when the control signal indicates to stop taking water, controlling the water delivery device to close.

[0022] In the above technical solution, the second control module is used to control the water delivery device to close according to the control signal from the pipeline machine indicating to stop taking water. In this way, the water purifier can stop replenishing purified water to the pipeline machine in time according to the needs of the pipeline machine. This can avoid excessive purified water in the first water storage device of the pipeline machine, which may cause the purified water in the first water storage device to overflow or be damaged due to excessive pressure.

[0023] Exemplarily, the water purifier also includes a second water level detection device, which is arranged in the second water storage device; the second control module is electrically connected to the second water level detection device, and the second control module is also used to control the water delivery device according to the water level information in the second water storage device detected by the second water level detection device, wherein the control of opening the water delivery device is only executed when the water level information in the second water storage device indicates that the current water level is higher than the third water level.

[0024] The above technical solution can prevent the water pump from running idle and affecting its service life when there is no water in the water purifier, or prevent the solenoid valve from frequently switching on and off to generate noise and shorten its service life. In addition, it ensures that the pipeline machine is replenished with purified water when there is sufficient water in the water purifier, thereby improving the user experience.

[0025] Exemplarily, the second control module is also used to send a feedback signal to the pipeline machine via the second communication device to control the pipeline machine to stop drawing water when the water level information in the second water storage device indicates that the current water level is lower than a third water level.

[0026] In the above technical solution, when the water volume is insufficient, the water purifier can provide feedback to the pipeline machine to stop taking water, thereby avoiding problems such as affecting the life of the water delivery device or generating noise.

[0027] Exemplarily, the water purifier also has a second purified water outlet and also includes a water outlet solenoid valve. The water outlet of the water delivery device is also connected to the second purified water outlet via the water outlet solenoid valve. The second control module is also used to: when the control signal indicates water extraction, control the water outlet solenoid valve to close; when the control signal indicates to stop water extraction, control the water outlet solenoid valve to open.

[0028] In the above technical solution, by setting a water outlet solenoid valve, the first clean water outlet and the second clean water outlet can be switched to supply water, so that water can be supplied to pipeline machines or equipment such as faucets respectively to meet user needs.

[0029] Some other embodiments of the present invention provide a control method for a pipeline machine. The pipeline machine has a purified water inlet and a water intake, and includes: a first water storage device, a first water level detection device, and a first communication device, wherein the water inlet of the first water storage device is connected to the purified water inlet through a first water path, the first water level detection device is arranged in the first water storage device, and the water outlet of the first water storage device is connected to the water intake; the control method of the pipeline machine includes: according to the water level information in the first water storage device detected by the first water level detection device, sending a control signal to the water purifier via the first communication device to control the water supply of the water purifier.

[0030] In the above technical solution, the pipeline machine can detect the water level in the first water storage device and send a corresponding control signal to the water purifier via the first communication device to realize automatic intelligent control of the water purifier. In this way, an intelligent interconnection between the pipeline machine and the water purifier is established, which significantly improves the user experience. In addition, the connecting pipe between the pipeline machine and the water purifier does not need to be under continuous pressure, which reduces the risk of water leakage and increases the service life.

[0031] Some other embodiments of the present application provide a control method for a water purifier. The water purifier has a raw water inlet and a first purified water outlet, and includes a water purification module, a second water storage device, a water delivery device, and a second communication device, wherein the water inlet of the water purification module is connected to the raw water inlet, the water inlet of the second water storage device is connected to the water outlet of the water purification module, the water outlet of the second water storage device is connected to the water inlet of the water delivery device, and the water outlet of the water delivery device is connected to the first purified water outlet; the control method for the water purifier includes: according to a control signal from a pipeline machine received via the second communication device, controlling the water delivery device to open or close, so as to supply water to or stop supplying water to the pipeline machine, wherein the pipeline machine is connected to the first purified water outlet.

[0032] In the above technical solution, the water purifier can control the water delivery device therein according to the control signal from the pipeline machine, and then control whether to supply water to the pipeline machine. This establishes an intelligent interconnection between the pipeline machine and the water purifier, and can intelligently control the water supply of the water purifier according to the status of the pipeline machine, significantly improving the user experience. In addition, the connecting pipe between the pipeline machine and the water purifier does not need to be under continuous pressure, which reduces the risk of water leakage and increases the service life.

DETAILED DESCRIPTION

[0042] In the following description, a large amount of details are provided so that the present invention can be thoroughly understood. However, it will be appreciated by those skilled in the art that the following description only exemplarily illustrates a preferred embodiment of the present invention, and the present invention can be implemented without one or more such details. In addition, in order to avoid confusion with the present invention, some technical features well known in the art are not described in detail.

[0043] In order to fully understand the embodiments of the present invention, detailed structures will be presented in the following description. Obviously, the implementation of the embodiments of the present invention is not limited to the specific details familiar to those skilled in the art. The preferred embodiments of the present invention are described in detail below, but in addition to these detailed descriptions, the present invention may also have other embodiments.

[0044] An embodiment of the present invention provides a pipeline machine. The pipeline machine has a purified water inlet for connecting to a water purifier so that the water purifier supplies water to the pipeline machine. The pipeline machine also has a water intake for users to take water. The pipeline machine according to an embodiment of the present invention will be described in detail below in conjunction with the accompanying drawings. Figure 1 FIG. 1 shows a schematic block diagram of a pipeline machine 100 according to an embodiment of the present application. Figure 1 As shown, the pipeline machine 100 includes a first water storage device 130 , a first water level detection device 131 , a first communication device 150 and a first control module 140 .

[0045] The water inlet of the first water storage device 130 is connected to the clean water inlet 110 through the first water channel, so as to obtain clean water and store it in the first water storage device 130. Exemplarily, the first water storage device 130 may include a water tank having an opening connected to the outside world, which can avoid the positive pressure or negative pressure in the water tank, resulting in the inability to inject or output clean water. Alternatively, the first water storage device 130 may also include a pressure barrel, and the interior of the pressure barrel is usually provided with components such as air bags, which can provide pressure for the clean water in the pressure barrel so that the clean water in the pressure barrel can flow out smoothly. The water outlet of the first water storage device 130 is connected to the water intake 101 of the pipeline machine 100. The user can take the clean water in the first water storage device 130 through the water intake 101.

[0046] The first water level detection device 131 is arranged in the first water storage device 130, and is used to detect the water level in the first water storage device 130. The first water level detection device 131 can be any existing or future developed water level sensor that can realize single-point detection or multi-point detection of water level. Exemplarily but not restrictively, the first water level detection device 131 can include a photoelectric water level sensor, an electrode water level sensor, a capacitive water level sensor, etc. Photoelectric water level sensors include integrated photoelectric water level sensors, separate photoelectric water level sensors, and multi-point photoelectric water level sensors. The first water level detection device 131 can be arranged on the inner wall of the first water storage device 130, so as to detect the water level in the first water storage device 130 and generate corresponding water level information. The first control module 140 is electrically connected to the first water level detection device 131, and can obtain the water level information.

[0047] The first control module 140 is electrically connected to the first water level detection device 131 and the first communication device 150. The first control module 140 can be used to send a control signal to the water purifier 200 via the first communication device 150 according to the water level information in the first water storage device 130 detected by the first water level detection device 131, so as to control the water supply of the water purifier 200. The water purifier 200 is connected to the purified water inlet 110 of the pipeline machine 100.

[0048] The first control module 140 can receive water level information in the first water storage device 130 from the first water level detection device 131. According to the water level information, the first control module 140 can determine whether the water purifier 200 is required to supply water to the pipeline machine 100, and then send a corresponding control signal. Exemplarily, when the water level in the first water storage device 130 is low, the water purifier 200 can be controlled to start water supply. When the water level in the first water storage device 130 is high, the water purifier 200 can be controlled to stop water supply.

[0049] The first communication device 150 can be used to communicate with the water purifier 200. It can be a wired communication device or a wireless communication device. The first communication device 150 can be any suitable communication device such as a 433MHz radio frequency communication module, a WiFi module, a Bluetooth module, etc. These communication modules can perform wireless signal transmission between two devices without a physical connection. Under the control of the first control module 140, the first communication device 150 can convert the control information into a wireless signal. Specifically, the first communication device 150 can send the above-mentioned wireless signal to the water purifier 200 to control the water purifier 200 to supply water to the pipeline machine 100. Preferably, in order to avoid interference from wireless signals in the environment, in one example, the first communication device can encode the control signal. For this example, the water purifier 200 can decode the control signal accordingly to obtain the control information carried in the control signal.

[0050] In the above technical solution, the pipeline machine 100 can detect the water level in the first water storage device 130 and send a corresponding control signal to the water purifier 200 via the first communication device 150, thereby realizing automatic intelligent control of the water purifier 200. Thus, an intelligent interconnection between the pipeline machine 100 and the water purifier 200 is established, which significantly improves the user experience. In addition, the connecting pipeline between the pipeline machine 100 and the water purifier 200 does not need to be under pressure continuously, which reduces the risk of water leakage and increases the service life.

[0051] Exemplarily, the first control module 140 sends a control signal to the water purifier 200 via the first communication device 150 according to the water level information in the first water storage device 130 detected by the first water level detection device 131, which may specifically include performing the following operations: When the first water level information in the first water storage device 130 indicates that the current water level is lower than the first water level, a control signal instructing water extraction is sent.

[0052] The first water level may be a water level threshold value set according to the water flow rate of the water intake 101 of the pipeline machine 100 and the user's water use habits. Specifically, the first water level may be close to the bottom of the first water storage device 130. For example, the first water level is 1 to 3 centimeters. When the first control module 140 obtains low water level information lower than the first water level, it may send a control signal indicating water intake to the water purifier 200 via the first communication device 150. The water purifier 200 is connected to the clean water inlet 110 of the pipeline machine 100. Using the control signal, the water purifier 200 may be controlled to supply water to the first water storage device 130 of the pipeline machine 100 via the clean water inlet 110.

[0053] In the above technical solution, when the water level in the first water storage device 130 is low, the water purifier 200 is controlled to replenish purified water in time. Thus, the amount of water in the first water storage device 130 of the pipeline machine 100 can be guaranteed, thereby ensuring that the pipeline machine 100 can provide purified water to the user in time.

[0054] Exemplarily, the pipeline machine 100 also includes a water intake detection device. The water intake detection device is arranged at the clean water inlet 110, and is used to detect the user's water intake operation and generate a water intake signal. The water intake detection device can be an input device such as a button or a touch screen. The water intake detection device can generate water intake information in response to the user's operation. The pipeline machine 100 can also be connected to a mechanical faucet, and the water intake detection device can be a high-pressure switch. When the user operates the faucet 300 to take water, the pressure in the water channel downstream of the high-pressure switch suddenly drops, and the high-pressure switch can generate water intake information according to the water pressure change. The first control module 140 is also electrically connected to the water intake detection device. The first control module 140 is also used to receive a water intake signal from the water intake detection device, wherein the first control module 140 sends a control signal indicating water intake, which is only executed when the first control module 140 receives a water intake signal from the water intake detection device.

[0055] It can be understood that when the user takes water, the water level in the first water storage device 130 drops. In an exemplary embodiment, after the user takes water, the water level in the first water storage device 130 drops below the first water level, and at this time, the first control module 140 sends a control signal indicating water taking. After receiving the control signal, the water purifier 200 replenishes the pipeline machine 100 with purified water. When the user does not take water, the amount of water in the first water storage device 130 in the pipeline machine 100 will not decrease because the user does not take water. At this time, even if the water level in the first water storage device 130 drops below the first water level due to water leakage caused by damage to the first water storage device 130, the first control module 140 does not send a control signal indicating water taking.

[0056] In the above technical solution, the pipeline machine 100 can replenish the first water storage device 130 in time only after the user takes water. In other time periods, there is no need to send a control signal indicating water taking according to the water level information in the first water storage device 130, which can reduce the power consumption of the pipeline machine 100 and achieve energy saving. In addition, in the event of a leak in the first water storage device 130 of the pipeline machine 100, the first water storage device 130 will not be replenished unnecessarily, thereby avoiding the waste of purified water.

[0057] Exemplarily, the first control module 140 sends a control signal to the water purifier 200 via the first communication device 150 according to the water level information in the first water storage device 130 detected by the first water level detection device 131, which may specifically include performing the following operations: When the water level information in the first water storage device 130 indicates that the current water level is higher than the second water level, a control signal instructing to stop taking water is sent.

[0058] The second water level may be a water level threshold value set according to the water flow rate of the water intake port 101 of the pipeline machine 100 and the user's water use habits. Specifically, the second water level may be close to the full water level of the first water storage device 130. For example, it may be 1 to 3 cm lower than the full water level of the first water storage device 130. When the first control module 140 obtains high water level information higher than the second water level, a control signal instructing to stop taking water may be sent to the water purifier 200 via the first communication device 150. With the control signal, the water purifier 200 connected to the water purification inlet 110 may be controlled to stop supplying water to the first water storage device 130 of the pipeline machine 100.

[0059] In the above technical solution, when the water level in the first water storage device 130 is high, the water purifier 200 is controlled to stop replenishing the purified water in time. In this way, the replenishment of water can be stopped in time when the first water storage device 130 is nearly full, so as to prevent the purified water in the first water storage device 130 from overflowing or being damaged due to excessive water pressure.

[0060] It can be understood that in the above description, control schemes for sending control signals indicating water extraction and stopping water extraction according to the water level information in the first water storage device 130 are respectively given. It can be understood that these two schemes can be executed separately. That is, in some embodiments, a control signal indicating water extraction is sent only according to the water level information. In these embodiments, a control signal indicating the stop of water extraction can be sent according to other information. Alternatively, the water purifier 200 can also automatically stop water extraction according to its own state, for example, according to the length of time or amount of water that the water purifier 200 has provided purified water. In some other embodiments, a control signal indicating the stop of water extraction is sent only according to the water level information. In these embodiments, the water purifier 200 can automatically supply water, for example, at a preset frequency. Of course, the user can also manually control the water purifier 200 to supply water or stop water supply.

[0061] It is understood that the above control schemes of sending control signals for instructing water intake and stopping water intake respectively can also be implemented together in one embodiment. In an exemplary embodiment, the first water level detection device 131 can be a single-point detection water level sensor. Figure 1 , the first water level detection device 131 may include two single-point detection water level sensors, respectively referred to as the first water level sensor and the second water level sensor. The first water level sensor and the second water level sensor are respectively arranged at the first water level and the second water level of the first water storage device 130. Among them, the first water level is lower than the second water level. That is, the first water level sensor is lower than the second water level sensor. The first water level sensor can be used to detect whether the current water level is lower than the first water level. The second water level sensor can be used to detect whether the current water level is higher than the second water level.

[0062] In the above technical solution, the first control module 140 can send different control signals based on the two single-point detection water level detection devices to control the water supply of the water purifier 200. The single-point detection water level detection device has a low cost, thereby reducing the cost of the pipeline machine 100. In addition, the above control solution uses simple logic to achieve automatic intelligent control of both water intake and water stop, which is not prone to errors.

[0063] Alternatively, the first water level detection device 131 may also be a water level sensor based on multi-point detection, such as a water level sensor based on hydraulic pressure. The first water level detection device 131 may be arranged at the bottom of the first water storage device 130. The detection range of the first water level detection device 131 includes the first water level and the second water level mentioned above. The multi-point detection water level sensor can more accurately detect the water level height in the first water storage device 130. In this embodiment, the pipeline machine 100 can support the user to set the first water level and the second water level mentioned above. Thus, a better user experience is provided for the user.

[0064] Exemplarily, a timer may be provided in the pipeline machine 100, which is used to start timing after the first control module 140 sends a control signal indicating water intake. When the counted time reaches the first time threshold, a control signal indicating to stop water intake is sent. In one embodiment, the first water level detection device 131 in the pipeline machine 100 may be a water level sensor for single-point detection. The water level sensor may be provided at the first water level, and generates low water level information when the current water level is lower than the first water level. When the first control module 140 obtains the low water level information, the water purifier 200 connected to the water purification inlet 110 may be controlled to supply water to the pipeline machine 100 via the first communication device 150, and the timer may be started to start timing. When the counted time reaches the first time threshold, a control signal to stop water intake is sent to the water purifier 200 connected to the water purification inlet 110 via the first communication device 150, so as to control the water purifier 200 to stop supplying water to the pipeline machine 100. Since the capacity of the first water storage device 130 is known, the flow rate of water supplied by the water purifier 200 may also be known; therefore, the value of the first time threshold may be set based on the two. After the water purifier 200 provides purified water for the pipeline machine 100 for the first time threshold, the first water storage device 130 may be substantially filled.

[0065] In the above technical solution, the pipeline machine 100 can send a control signal to control the water purifier 200 to stop taking water according to the time counted by the timer. This technical solution is also easy to implement and not prone to error.

[0066] Exemplarily, the pipeline machine 100 further includes a water inlet solenoid valve 120, which is disposed on the first water path between the first water storage device 130 and the clean water inlet 110 of the pipeline machine 100. The first control module 140 is electrically connected to the water inlet solenoid valve 120, and the first control module 140 is further used to control the water inlet solenoid valve 120 to be opened or closed according to the first water level information in the first water storage device 130 detected by the first water level detection device 131.

[0067] As described above, illustratively, the first water storage device 130 may include a pressure barrel, and when the first water level information in the first water storage device 130 indicates that the current water level is lower than the first water level, the water purifier 200 replenishes the clean water into the pressure barrel through the clean water inlet 110, and the first control module 140 may control the water inlet solenoid valve 120 to open. When the first water level information in the first water storage device 130 indicates that the current water level is higher than the second water level, the water purifier 200 stops replenishing water for the first water storage device 130, and the water inlet solenoid valve 120 may be controlled to close. In this way, the clean water in the pressure barrel can be prevented from flowing back into the water purifier 200.

[0068] In another exemplary embodiment, the water purifier 200 may be connected to multiple pipeline machines 100, or may be provided with other water outlets, such as a water outlet for connecting to a faucet 300. When the water purifier 200 replenishes water to one of the pipeline machines 100, or provides purified water to other water outlets, the water inlet solenoid valve 120 can prevent the water level in the first water storage device 130 of the pipeline machine 100 that does not need to be replenished from continuing to rise, causing overflow, etc.

[0069] In the above technical solution, the pipeline machine 100 is provided with a water inlet solenoid valve 120. This can not only prevent the water in the first water storage device 130 from flowing back, but also effectively avoid the first water storage device 130 from overflowing due to excessive water or being damaged due to excessive water pressure.

[0070] Exemplarily, the first control module 140 is also used to receive a feedback signal from the water purifier 200 via the first communication device 150, and control the water inlet solenoid valve 120 to close after receiving the feedback signal, wherein the feedback signal indicates that the water level in the second water storage device of the water purifier 200 is lower than the third water level.

[0071] On the one hand, the first water storage device 130 may include a pressure barrel. In the process of controlling the water purifier 200 to replenish water to the pressure barrel and opening the water inlet solenoid valve 120, if the water purifier 200 is in a water shortage state because the water level in the second water storage device is lower than the third water level and cannot replenish water to the pressure barrel, the pressure barrel may cause residual purified water therein to flow back to the water purifier 200 due to the internal pressure.

[0072] On the other hand, the pipeline connecting the water purifier 200 to the purified water inlet 110 of the pipeline machine 100 may also be connected to other water intake equipment, such as faucets, etc. Compared with the pipeline machine 100, other water intake equipment may need purified water more urgently. In other words, the water use priority of other water intake equipment may be higher. When the water level of the second water storage device in the water purifier 200 is lower than the third water level, the water purifier 200 can give priority to supplying water to other water intake equipment. At this time, the first control module 140 can receive the feedback signal of the water purifier 200 via the first communication device 150, and control the water inlet solenoid valve 120 to close.

[0073] Optionally, after receiving the feedback signal, the first control module 140 of the pipeline machine 100 can start timing at the same time, and send a control signal indicating water extraction again after a certain period of time, and repeat this cycle until water extraction is completed and a control signal to stop water extraction is sent. Alternatively, the pipeline machine 100 can also wait for another prompt signal from the water purifier 200 and then send a control signal indicating water extraction again, and repeat this cycle until water extraction is completed and a control signal to stop water extraction is sent. It can be understood that the prompt signal can indicate that the water purifier 200 can supply water to the pipeline machine 100.

[0074] In the above technical solution, the first control module 140 receives the feedback signal that the water purifier 200 cannot supply water via the first communication device 150, and controls the water inlet solenoid valve 120 to close according to the feedback signal. This can not only prevent the water of the pipeline machine 100 from flowing back to the water purifier 200, but also give priority to providing purified water to the water purifier 200 when it is connected to a water intake device with a higher priority.

[0075] The embodiment of the present invention further provides a water purifier 200. The water purifier 200 can be used to supply water to the pipeline machine 100. The water purifier 200 can be a variety of types of water purifiers 200, including but not limited to a desktop water purifier 200 or an under-sink water purifier 200.

[0076] Figure 2 FIG. 2 shows a schematic diagram of a water purifier 200 according to an embodiment of the present invention. Figure 2 As shown, the water purifier 200 has a raw water inlet 201 and a first purified water outlet 202, and the water purifier 200 includes a water purification module, a second water storage device, a water delivery device, a second communication device and a second control module.

[0077] The water inlet of the water purification module is connected to the raw water inlet 201. The water purification module may include a central filter element such as a reverse osmosis filter element, an ultrafiltration filter element, a nanofiltration filter element, or a composite filter element composed of any two or more of them. For reverse osmosis filter elements and nanofiltration filter elements, the water needs to be pressurized before entering the filter element, so the water purification module may also include a booster pump. Optionally, the water purification module may also include a pre-filter element, which is located before the central filter element and is used to perform preliminary filtration on the water entering the central filter element to extend the service life of the central filter element. The reverse osmosis filter element or the nanofiltration filter element will produce a certain proportion of concentrated water during the filtration process, and the generated concentrated water is discharged from the concentrated water port 203. Figure 2 As shown in the water purifier 200, the water purification module in the water purifier 200 may include a pre-filter element 211, a booster pump 212 and a central filter element 213 arranged in series. Optionally, a raw water solenoid valve 214 may be provided between the pre-filter element 211 and the booster pump 212. The concentrated water produced by the reverse osmosis filter element during the water production process is discharged to the concentrated water outlet 203 through the concentrated water solenoid valve 215.

[0078] The water inlet of the second water storage device is connected to the water outlet of the water purification module. The second water storage device is similar to the first water storage device 130 and may also include a water tank or a pressure barrel. The water outlet of the second water storage device is connected to the water inlet of the water delivery device. The water outlet of the water delivery device is connected to the first purified water outlet 202. The water delivery device is used to control the purified water to flow out of the second water storage device.

[0079] exist Figure 2In the illustrated embodiment, the second water storage device includes a water tank 220. The water tank 220 has no pressure on the purified water outputted therefrom. When the water purifier 200 is disposed at a higher position, water can be supplied to the first purified water outlet 202 and other equipment on the pipeline by gravity. The water purifier 200 can also be disposed at a location such as under the kitchen. The water delivery device may include a water pump 230, which can provide output power for the purified water in the water tank 220 so that the water outlet position is not restricted by height. When the water pump 230 is turned on and operated, the purified water in the water tank 220 can be outputted to the first purified water outlet 202. When the water pump 230 is turned off, i.e., it stops operating, the purified water in the water tank 220 no longer flows out of the water tank 220.

[0080] In an embodiment not shown, the second water storage device includes a pressure barrel. The pressure barrel can provide output pressure for the purified water. The water delivery device may include a solenoid valve. At this time, the water purifier 200 directly supplies water to the outside through the pressure barrel, and controls whether the purified water in the pressure barrel flows out through the solenoid valve. When the solenoid valve is opened, the purified water in the pressure barrel can be output to the first purified water outlet 202. When the solenoid valve is closed, the purified water in the pressure barrel no longer flows out of the pressure barrel.

[0081] The second control module is electrically connected to the second communication device and the water delivery device. The second control module is used to control the water delivery device to open or close according to the control signal from the pipeline machine 100 received via the second communication device, so as to supply water to the pipeline machine 100 or stop supplying water. The pipeline machine 100 is connected to the first purified water outlet 202 of the water purifier 200.

[0082] The second communication device can be used to communicate with the pipeline machine 100, for example, with the first communication device 150 in the pipeline machine 100. Similar to the first communication device 150, the second communication device can be a wired communication device or a wireless communication device. The second communication device can be any suitable communication device such as a 433MHz radio frequency communication module, a WiFi module, a Bluetooth module, etc. These communication modules can perform wireless signal transmission between two devices without a physical connection. Under the control of the second control module, the second communication device can convert the wireless signal into control information. Specifically, the second communication device can send the above-mentioned control signal from the pipeline machine 100 to the second control module, so that the second control module controls the water delivery device in the water purifier 200 to supply water to the pipeline machine 100100. Preferably, in order to avoid interference with wireless signals in the environment, in one example, the second communication device can decode the wireless signal to obtain the control information carried in the control signal.

[0083] The second control module can analyze the control signal received via the second communication device to determine the needs of the pipeline machine 100. When the pipeline machine 100 wants to take water, the second control module can control the water delivery device to open; when the pipeline machine 100 wants to stop taking water, the second control module can control the water delivery device to close.

[0084] In the above technical solution, the water purifier 200 can control the water delivery device therein according to the control signal from the pipeline machine 100, and then control whether to supply water to the pipeline machine 100. This establishes an intelligent interconnection between the pipeline machine 100 and the water purifier 200, and can intelligently control the water supply of the water purifier 200 according to the state of the pipeline machine 100, which significantly improves the user experience. In addition, the connecting pipeline between the pipeline machine 100 and the water purifier 200 does not need to be under pressure continuously, which reduces the risk of water leakage and increases the service life.

[0085] Exemplarily, the second control module controls the water delivery device to open or close according to the control signal received from the pipeline machine 100 via the second communication device, including the following operations: when the control signal indicates water intake, the water delivery device is controlled to open. As mentioned above, when the water level in the first water storage device 130 in the pipeline machine 100 is low, it may need the water purifier 200 to replenish purified water for it. At this time, the pipeline machine 100 can send a control signal indicating water intake to the water purifier 200. The second control module can control the water delivery device to open according to the control signal.

[0086] In the above technical solution, the second control module is used to control the water delivery device to open according to the control signal indicating water intake from the pipeline machine 100. In this way, the water purifier 200 can replenish purified water to the pipeline machine 100 in time according to the needs of the pipeline machine 100, thereby ensuring that the user can smoothly take water from the pipeline machine 100.

[0087] Exemplarily, the second control module controls the water delivery device to open or close according to the control signal received from the pipeline machine 100 via the second communication device, including the following operations: when the control signal indicates to stop taking water, the water delivery device is controlled to close. As mentioned above, when the water level in the first water storage device 130 in the pipeline machine 100 is high, it may require the water purifier 200 to stop replenishing purified water for it. At this time, the pipeline machine 100 can send a control signal to the water purifier 200 to indicate to stop taking water. The second control module can control the water delivery device to close according to the control signal.

[0088] In the above technical solution, the second control module is used to control the water delivery device to close according to the control signal from the pipeline machine 100 indicating to stop taking water. In this way, the water purifier 200 can stop replenishing purified water to the pipeline machine 100 in time according to the needs of the pipeline machine 100. This can prevent the first water storage device 130 of the pipeline machine 100 from having too much purified water, thereby causing the purified water in the first water storage device 130 to overflow or be damaged due to excessive pressure.

[0089] It can be understood that, as described above in the description of the pipeline machine 100, in one embodiment, the water delivery device can be controlled to open only based on the control signal from the pipeline machine 100, and the water purifier 200 can control the water delivery device to close at an appropriate time.

[0090] Exemplarily, the water purifier 200 may include a timer. It is used to start timing after the second control module receives a control signal indicating water intake. When the counted time reaches the second time threshold, the water delivery device is controlled to close. Since the capacity of the first water storage device 130 of the pipeline machine 100 is known, the flow rate of water supplied by the water purifier 200 may also be known; therefore, the value of the second time threshold can be set based on the two. After the water purifier 200 provides the pipeline machine 100 with purified water for the second time threshold, the first water storage device 130 can be roughly filled.

[0091] In the above technical solution, the water purifier 200 can control the water delivery device to close according to the time counted by the timer. This technical solution is also easy to implement and is not prone to errors.

[0092] In another embodiment, the water delivery device can be controlled to be closed only according to the control signal from the pipeline machine 100, and the water purifier 200 can control the water delivery device to open at an appropriate time.

[0093] Exemplarily, the water purifier 200 can supply water to the pipeline machine 100 at a preset frequency. In other words, the water purifier 200 can automatically control the water delivery device to open at preset intervals to supply water to the pipeline machine 100. The preset frequency or preset time can be set according to the water usage of the pipeline machine 100 and the volume of the first water storage device 130 in the pipeline machine 100. Thus, when the water level in the first water storage device 130 in the pipeline machine 100 is likely to be lower than the first water level, the water delivery device is controlled to open.

[0094] In another embodiment, the water delivery device can be controlled to open and close according to different control signals from the pipeline machine 100. According to the above description, those skilled in the art can understand the specific implementation of this embodiment, and for the sake of brevity, it will not be repeated here.

[0095] Exemplarily, the water purifier 200 further includes a second water level detection device 221. The second water level detection device 221 is disposed in the second water storage device. Figure 2 As mentioned above, the second water level detection device 221 is similar to the first water level detection device 131, and can be used to detect the water level in the second water storage device and output corresponding water level information. The second control module is electrically connected to the second water level detection device 221. The second control module is also used to control the water delivery device according to the water level information in the second water storage device detected by the second water level detection device 221. Among them, the second control module controls the operation of opening the water delivery device, which is only executed when the water level information in the second water storage device indicates that the current water level is higher than the third water level.

[0096] It can be understood that when the water level in the second water storage device of the water purifier 200 is low, it is difficult to provide clean water for other equipment. When the second water level detection device 221 detects that the water level in the second water storage device is lower than the third water level, the second control module will not open the water delivery device. If the water delivery device is in an open state at this time, the second control module will control the water delivery device to close. At this time, the water purification module can be used to replenish clean water to the second water storage device. The water delivery device will only be opened when the water level in the second water storage device is higher than the third water level. Preferably, in order to avoid the water purifier 200 from delivering water intermittently and affecting the user experience, if the water level shown in the water level information detected by the second water level detection device 221 is lower than the third water level, even if the water purification module replenishes clean water so that the water level is higher than the third water level, the water delivery device will not be opened immediately, but will wait for a certain period of time, or wait for the water level to reach the fourth water level higher than the third water level, before the water delivery device is opened.

[0097] The above technical solution can prevent the water pump 230 from running idle and affecting its service life when there is no water in the water purifier 200, or prevent the electromagnetic valve from frequently switching on and off to generate noise and shorten its service life. In addition, it ensures that the pipeline machine 100 is replenished with purified water when there is sufficient water in the water purifier 200, thereby improving the user experience.

[0098] Exemplarily, the second control module is also used to send a feedback signal to the pipeline machine 100 via the second communication device to control the pipeline machine 100 to stop taking water when the water level information in the second water storage device indicates that the current water level is lower than the third water level.

[0099] As described above, when the water level in the second water storage device of the water purifier 200 is low and it cannot replenish purified water for the pipeline machine 100, in order to avoid affecting the water use of other equipment or the backflow of purified water of the pipeline machine 100, a feedback signal can be sent to the pipeline machine 100 through the second communication device, thereby controlling the pipeline machine 100 to stop taking water. Exemplarily, the pipeline machine 100 can close its water inlet solenoid valve 120 according to the feedback signal.

[0100] Exemplarily, when the water level information detected by the second water level detection device 221 indicates that the water level is higher than the fourth water level, the water purifier 200 can send a prompt signal to the pipeline machine 100 via the second communication device. The fourth water level is higher than the third water level. The pipeline machine 100 can reopen the water inlet solenoid valve 120 according to the prompt signal.

[0101] In the above technical solution, when the water volume is insufficient, the water purifier 200 can provide feedback to the pipeline machine 100 to stop taking water, thereby avoiding the above problems such as affecting the life of the water delivery device or generating noise.

[0102] Exemplarily, the water purifier 200 further has a second purified water outlet 204 and also includes a water outlet solenoid valve 240, and the water outlet of the water delivery device is also connected to the second purified water outlet 204 via the water outlet solenoid valve 240. The second control module is also used to control the water outlet solenoid valve 240 to close when the control signal indicates water extraction; and control the water outlet solenoid valve 240 to open when the control signal indicates to stop water extraction.

[0103] Continue to refer Figure 2 , the water outlet of the water pump 230 is also connected to the second clean water outlet 204 via the water outlet solenoid valve 240. The second clean water outlet 204 can be connected to the tap 300. When the control signal indicates to take water, the water pump 230 is controlled to deliver water to the pipeline machine 100, and the water outlet solenoid valve 240 is controlled to be closed. This can prevent the clean water from flowing out through the second clean water outlet 204. When the control signal indicates to stop taking water, the water pump 230 is controlled to stop delivering water to the pipeline machine 100, and the water outlet solenoid valve 240 is controlled to be opened. At this time, the water pump 230 can deliver water to the outside through the tap 300.

[0104] In the above technical solution, by setting the water outlet solenoid valve 240, the first clean water outlet 202 and the second clean water outlet 204 can be switched to supply water, so that water can be supplied to the pipeline machine 100 or equipment such as the faucet 300 respectively to meet user needs.

[0105] The embodiment of the present invention also discloses a control method of a pipeline machine 100. The pipeline machine 100 may be the pipeline machine 100 as described above. Specifically, the pipeline machine 100 has a clean water inlet 110 and a water intake 101. The pipeline machine 100 includes a first water storage device 130, a first water level detection device 131 and a first communication device 150. The water inlet of the first water storage device 130 is connected to the clean water inlet 110 through a first water path. The first water level detection device 131 is disposed in the first water storage device 130. The water outlet of the first water storage device 130 is connected to the water intake 101.

[0106] The control method of the pipeline machine 100 includes: sending a control signal to the water purifier 200 via the first communication device 150 according to the water level information in the first water storage device 130 detected by the first water level detection device 131, so as to control the water supply of the water purifier 200.

[0107] Exemplarily, the control method of the pipeline machine 100 may specifically include the following steps S1 and / or S2.

[0108] Step S1, when the water level information in the first water storage device 130 indicates that the current water level is lower than the first water level, a control signal instructing water intake is sent.

[0109] Step S2, when the water level information in the first water storage device 130 indicates that the current water level is higher than the second water level, a control signal instructing to stop taking water is sent.

[0110] Exemplarily, the pipeline machine 100 further includes a water intake detection device, which is disposed at the purified water inlet 110. In the control method of the pipeline machine 100, the step S1 of sending a control signal indicating water intake is only executed when the water intake detection device receives a water intake signal.

[0111] Exemplarily, the pipeline machine 100 further includes a water inlet solenoid valve 120 disposed on the first waterway. The control method of the pipeline machine 100 further includes: controlling the water inlet solenoid valve 120 to open or close according to the water level information in the first water storage device 130 detected by the first water level detection device 131.

[0112] Exemplarily, the control method of the pipeline machine 100 further includes: receiving a feedback signal from the water purifier 200 via the first communication device 150, and controlling the water inlet solenoid valve 120 to close after receiving the feedback signal. The feedback signal indicates that the water level in the second water storage device of the water purifier 200 is lower than the third water level. In other words, opening the water inlet solenoid valve 120 is performed only when the feedback signal is not received.

[0113] Figure 3 FIG. 1 is a schematic flow chart of a control method of a pipeline machine 100 according to an embodiment of the present invention. Figure 3As shown, first, the water intake detection signal of the water intake detection device is obtained. Subsequently, if the water level information detected by the first water level detection device 131 indicates that the current water level is lower than the first water level, a control signal indicating water intake is sent through the first communication module. If a feedback signal is received from the water purifier 200 via the first communication device 150, indicating that the water level in the second water storage device is lower than the third water level, the water inlet solenoid valve 120 is controlled to be closed and water intake is stopped. If no feedback signal is received, the water inlet solenoid valve 120 is controlled to be opened. It can be understood that during the process of opening the water inlet solenoid valve 120, if a feedback signal is received from the water purifier 200 at any time, the water inlet solenoid valve 120 is controlled to be closed. As the water purifier 200 replenishes water into the first water storage device 130, the water level therein gradually rises. When the water level information detected by the first water level detection device 131 indicates that the current water level is higher than the second water level, the water inlet solenoid valve 120 is controlled to close, and a control signal to stop taking water is sent through the first communication module, and the water supply from the water purifier 200 to the pipeline machine 100 is completed.

[0114] The embodiment of the present invention also discloses a control method of a water purifier 200. The water purifier 200 may be the water purifier 200 as described above. The water purifier 200 has a raw water inlet 201 and a first purified water outlet 202. The water purifier 200 includes a water purification module, a second water storage device, a water delivery device, and a second communication device. The water inlet of the water purification module is connected to the raw water inlet 201. The water inlet of the second water storage device is connected to the water outlet of the water purification module. The water outlet of the second water storage device is connected to the water inlet of the water delivery device. The water outlet of the water delivery device is connected to the first purified water outlet 202.

[0115] The control method of the water purifier 200 includes: controlling the water delivery device to open or close according to a control signal from the pipeline machine 100 received via the second communication device to supply water to or stop supplying water to the pipeline machine 100, wherein the pipeline machine 100 is connected to the first purified water outlet 202.

[0116] Exemplarily, the control method of the water purifier 200 may specifically include the following steps S3 and / or S4.

[0117] Step S3, when the control signal indicates to take water, control the water delivery device to open.

[0118] Step S4, when the control signal indicates to stop taking water, the water delivery device is controlled to be closed.

[0119] Exemplarily, the water purifier 200 further includes a second water level detection device 221. The second water level detection device 221 is disposed in the second water storage device. The control method of the water purifier 200 further includes: controlling the water delivery device according to the water level information in the second water storage device detected by the second water level detection device 221, wherein the above step S3 controls the water delivery device to be turned on, and is executed only when the water level information in the second water storage device indicates that the current water level is higher than the third water level.

[0120] Exemplarily, the control method of the water purifier 200 also includes: when the water level information in the second water storage device indicates that the current water level is lower than the third water level, sending a feedback signal to the pipeline machine 100 via the second communication device to control the pipeline machine 100 to stop drawing water.

[0121] Exemplarily, the water purifier 200 further includes a second purified water outlet 204 and a water outlet solenoid valve 240. The water outlet of the water delivery device is also connected to the second purified water outlet 204 via the water outlet solenoid valve 240. The control method of the water purifier 200 further includes: when the control signal indicates water extraction, controlling the water outlet solenoid valve 240 to close; when the control signal indicates to stop water extraction, controlling the water outlet solenoid valve 240 to open.

[0122] Figure 4 A schematic flow chart of a control method of a water purifier 200 according to an embodiment of the present invention is shown. After receiving a control signal indicating water extraction via a second communication device, the water level information in the second water storage device is obtained through a second water level detection device. If the current water level in the second water storage device is lower than the third water level, the water delivery device is controlled to be closed, and a feedback signal is sent to the pipeline machine 100 via the second communication device. If the current water level in the second water storage device is higher than the third water level, the water outlet solenoid valve 240 is controlled to be closed, and the water delivery device is controlled to be opened, so that the purified water flows to the pipeline machine 100 only through the first purified water outlet 202. It can be understood that at any time during the process of opening the water delivery device, if the current water level in the second water storage device is lower than the third water level, the water delivery device is controlled to be closed. When a control signal to stop water extraction is received via the second communication device, the water delivery device is controlled to be closed, and the water outlet solenoid valve 240 is controlled to be opened. At this time, the user can obtain purified water through the second purified water outlet 204, and the purified water will not be provided to the pipeline machine 100.
