[0035] To make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0036] At present, a large commercial water purification machine has two water purification systems combined in the internal waterway due to the large flow demand. The pressure switches of the two water purification systems are needed to control water outlet respectively. When a user has a water taking action, the water outlet electromagnetic valve is actuated. The internal pressure of the water purification machine changes. The two pressure switches detect the pressure change and act to control the two water purification systems to produce water respectively. After water production is completed, the waterway is combined to flow through the water outlet branch. The water is discharged at a preset flow rate at the water outlet.

[0037] However, due to the working conditions of the commercial water purification machine and the external conditions such as the service life limitation of the pressure switch itself, the service life of the pressure switch cannot meet the long-term service life demand of the commercial parts. The pressure switch is prone to damage. One of the water purification systems cannot take water normally. Moreover, due to the condition limitation, the after-sales maintenance is not convenient. The reliability of the whole commercial water purification machine is seriously affected.

[0038] According to the embodiments of the present application, a gas stove control method embodiment is provided. It should be noted that the steps shown in the flowchart of the drawings can be executed in a computer system such as a group of computer executable instructions. Although the logical order is shown in the flowchart, in some cases, the steps shown or described herein can be executed in a different order.

[0039] In the present embodiment, a water purification equipment water production control method is provided. The method can be used for a master control chip such as a CPU, a single-chip microcomputer and the like of a water purification equipment. The water purification equipment includes two water purification systems. A pressure switch is arranged at the water outlet of each water purification system to detect the water pressure in the corresponding water purification system, Figure 1 is a flowchart of a gas stove control method according to an embodiment of the present application, as shown in Figure 1 The flowchart includes the following steps:

[0040] Step S101, the switch states of the pressure switches corresponding to the two water purification systems are monitored.

[0041] Specifically, when the water purification equipment has a water outlet demand, the water pressure inside the two water purification systems changes so that the corresponding pressure switch is opened, for example, when a user performs water taking from the water purification equipment by operating the display screen or the water outlet button of the water purification equipment, it is determined that the water purification equipment has a water outlet demand, and accordingly, when the water purification equipment does not have a water outlet demand, the water pressure inside the two water purification systems remains constant, and the corresponding pressure switch is closed.

[0042] Further, the monitoring of the on-off state of the two water purification system pressure switches can be specifically achieved by connecting the circuits in which the two pressure switches are located to the signal input port of the main control chip, for example, connecting the two pressure switches to the signal input port of one main control chip respectively, or connecting the two pressure switches in parallel and then connecting them to the signal input port of one main control chip. When a user takes water from the water purification equipment, the corresponding electromagnetic valve in the water purification equipment operates to start water outlet, the pressure inside the water purification system changes, the pressure switch detects the pressure change and starts to operate, the pressure switch performs an opening operation and sends a corresponding switch operation signal to the main control chip. After receiving the signal, the main control chip determines that the pressure switch is in an open state. Conversely, when the water purification equipment does not have water outlet, the pressure inside the water purification system is stable, and the two pressure switches are both in a closed state, no operation signal will be sent to the main control chip. At this time, the main control chip determines that the pressure switch is in a closed state without receiving the operation signal sent by the pressure switch, thereby achieving the monitoring of the on-off state of the two pressure switches.

[0043] It should be noted that in actual application, other schemes capable of achieving pressure switch state monitoring can also be used, as long as the pressure switch monitoring function can be achieved, and the present application is not limited thereto.

[0044] Step S102, after monitoring the opening of any water purification system corresponding pressure switch, control the two water purification systems to produce water.

[0045] The embodiment of the present application monitors the on-off state of the pressure switches of the two water purification systems, and controls the two water purification systems to produce water after monitoring the opening of any water purification system corresponding pressure switch, thereby avoiding the problem that the water purification system cannot operate normally due to the damage of a single pressure switch, enhancing the reliability of the water purification equipment as a whole and improving the user experience.

[0046] In the present embodiment, a water purification equipment water production control method is provided, which can be used for the main control chip of the water purification equipment, such as CPU, single-chip microcomputer, etc. The water purification equipment comprises two water purification systems, and a pressure switch is arranged at the water outlet of each water purification system to detect the water pressure inside the corresponding water purification system, Figure 2 is a flow chart of the gas stove control method according to the embodiment of the present application, asFigure 2 As shown in the figure, the flow includes the following steps:

[0047] In step S201, the switch states of the pressure switches corresponding to the two water purification systems are monitored. Figure 1 The related description of step S101 is shown in the figure and will not be repeated here.

[0048] In step S202, after monitoring the opening of any pressure switch corresponding to the two water purification systems, the two water purification systems are controlled to produce water.

[0049] Specifically, the step S202 of controlling the two water purification systems to produce water includes controlling the two water purification systems to produce water synchronously.

[0050] The embodiment of the application can solve the problem of affecting the operation performance of the whole machine due to the asynchronous opening time of the two pressure switches, and enhance the reliability of the whole machine by controlling the two water purification systems to produce water synchronously.

[0051] Further, the step S202 specifically includes:

[0052] In step S2021, the water production amount of the two water purification systems is determined based on the continuous opening time of the pressure switch.

[0053] Specifically, when the user takes water from the water purification device, the water pressure inside the two water purification systems is constantly changing, and in this process, due to the constant change of the internal pressure, the pressure switch will always be in the open state. The longer the user takes water, the longer the pressure switch is opened, and the greater the loss of purified water inside the water purification device. Therefore, the water production amount of the two water purification systems can be determined according to the continuous opening time of the pressure switch to meet the demand of storing purified water inside the water purification device.

[0054] Further, in actual application, the water flow rate of the water purification device can be obtained, and the corresponding relationship between the water flow rate and the water output amount changing with time is established, and then the water output amount corresponding to the continuous opening time of the pressure switch is calculated according to the relationship, that is, the water production amount of the two water purification systems is obtained.

[0055] In step S2022, the two water purification systems are controlled to produce water based on the water production amount.

[0056] The embodiment of the application determines the water production amount of the two water purification systems by using the continuous opening time of the pressure switch, realizes accurate control of water production of the water purification device, and improves the performance of the whole machine and the user experience.

[0057] In step S203, after monitoring that the pressure switches corresponding to the two water purification systems are closed, the two water purification systems are controlled to stop producing water.

[0058] Specifically, when the water purification equipment stops the water taking action, the internal pressure of the water purification system recovers, the corresponding pressure switch is in the closed state, and the action signal is no longer sent. At this time, the water purification system can be controlled to stop water making, so as to realize the automatic control of water making of the water purification system. It should be emphasized that in actual application, if the water making speed of the water purification equipment is less than the water outlet speed, the water purification system can also be controlled to stop water making after a certain period of time when it is monitored that both of the corresponding pressure switches of the two water purification systems are closed, or the water purification system is controlled to stop water making when it is monitored that the water making amount of the water purification system reaches the water making amount of the two water purification systems determined by the duration of the continuous opening of the pressure switch, so as to maintain the constant storage amount of water in the water purification equipment. Only as an example, the present application is not limited thereto.

[0059] The embodiment of the present application realizes the automatic intelligent control of water making of the water purification equipment by controlling the two water purification systems to stop water making after it is monitored that both of the corresponding pressure switches of the two water purification systems are closed, and improves the user experience.

[0060] The embodiment of the present application provides a water purification equipment, which comprises: two water purification systems, a pressure switch is arranged at the water outlet of each water purification system for detecting the water pressure in the corresponding water purification system, and the water purification equipment further comprises: a main control chip, which is used to execute the water purification equipment water making control method provided by the above-mentioned method embodiment, and details are not repeated here.

[0061] In some optional embodiments, the two pressure switches are connected in parallel and then connected to the signal input port of the main control chip.

[0062] The embodiment of the present application avoids the problem that a single water purification system cannot work normally due to damage of a single pressure switch, which affects the user experience, improves the stability of the water purification equipment, and improves the user experience.

[0063] In the embodiment of the present application, the water purification equipment is a commercial water purification machine.

[0064] The specific working process and working principle of the water purification equipment water making control scheme provided by the embodiment of the present application will be described in detail below in combination with a specific application example.

[0065] Taking a commercial water purification machine as an example, since the existing commercial machine is composed of two water purification systems (referred to as two water path systems in this example), the existing conventional water making logic is: after the water flows into the commercial machine, it is divided in the machine, and flows into the two water path systems respectively. The two water path systems are relatively independent, and only have their own pressure switches to control water making. After water making is completed, the water flows through the water outlet branch through water path combination, and flows out at the preset flow rate at the water outlet.

[0066] The embodiment of the present application is based on the actual problems of traditional pressure switch failure and after-sales replacement difficulty, and proposes a control method for improving the pressure switch, which can effectively prolong the service life of the pressure switch. The purpose can be achieved by software and hardware methods:

[0067] The existing software scheme is shown in Figure 3 As shown, the two pressure switches on the two waterway systems correspond to two different I / O ports on the main control chip (main control IC) of the water purification equipment respectively. When the two I / O ports receive signals sent by the pressure switches due to pressure changes respectively, the two systems can start to control the subsequent actions. When any pressure switch is damaged, the main control chip cannot receive the signal sent by the pressure switch, and the corresponding waterway system cannot perform the subsequent action. Since the commercial water purifier is a large-flow water purifier, two waterway systems are needed to control the water output to ensure that the water output reaches the preset water output. If one system performs water output first, the water output will be small, which will affect the user experience.

[0068] In the embodiment of the present application, when the signal sent by the pressure switch is received by any one of the two I / O ports, the main control chip judges that both I / O ports have received the signal, and then controls the two waterway systems to start the subsequent water production action. Under this logic, when one of the pressure switches is damaged, the other pressure switch can still send signals normally, and the two waterway systems can also work normally, and the whole machine cannot run due to the damage of one pressure switch. This method can also ensure that the opening time of the pressure switch is consistent, can ensure that the water production is started at the same time, and can improve the user experience. This method can effectively prolong the service life of the pressure switch from the software, and solve the problem of inconsistent opening time of the pressure switch.

[0069] Hardware scheme: Currently, there is one pressure switch on each of the two waterway systems. When the system has water output demand, the electromagnetic valve acts, the pressure changes, the pressure switch detects the pressure change and starts to act, and sends a signal to the main control chip to start the subsequent water production action.

[0070] In the embodiment of the present application, as shown in Figure 4As shown, by connecting two pressure switches in parallel from the hardware circuit, the two pressure switches share an I / O port of a master control chip, i.e., a master IC. When the water purification equipment has a water outlet demand, such as a water taking action, the internal electromagnetic valve of the water purification equipment is actuated, the internal pressure changes, and the parallel pressure switches detect the pressure change and start to act. When any one of the pressure switches detects an action signal, the master control chip can make the two water systems perform subsequent water production actions. After the water taking action is stopped, the internal pressure returns, and the two pressure switches are closed at the same time and no longer send signals. When one of the pressure switches fails, the other pressure switch can work normally to maintain the working state of the entire machine. Only when both of the pressure switches fail, the entire machine cannot work normally. The pressure switch opening time can be ensured to be consistent, the water production can be ensured to be started simultaneously, one I / O port of the chip can be saved, and hardware resources can be saved.

[0071] Since the commercial machine needs to ensure large flow, two pressure switches are needed to control the water outlet of two water purification systems. However, the pressure switch is limited by the use environment and the service life, and the pressure switch may be damaged. The embodiment of the present application provides two pressure switch control methods, which can effectively prolong the service life of the pressure switch by changing and optimizing the software control logic or the hardware circuit connection scheme of the pressure switch, solve the problem of different opening times of the pressure switch, and enhance the reliability of the entire machine.

[0072] It should be noted that, in the above description, Figure 3 and Figure 4 The load in the above description refers to a water production assembly of the water purification system, which is controlled by the master IC to produce water.
