[0027] In order to have a clearer understanding of the technical features, objectives and effects of the present application, the specific embodiments of the present application will be described with reference to the accompanying drawings, in which the same reference numerals represent the same or similar components having the same function.

[0028] In the following description, a large number of specific details are set forth in order to facilitate a thorough understanding of the present application, however, the present application can also be implemented in other ways different from those described herein, and therefore, the protection scope of the present application is not limited by the specific embodiments disclosed below.

[0029] As described in the background, the existing water dispenser in the prior art has the problem that when reaching the boiling stage, air bubbles will accumulate in the pipeline, blocking the water pump and the water outlet pipeline, and water cannot be immediately and smoothly discharged. The common water dispensers on the market have not solved this problem.

[0030] In order to solve the above problem, the technical scheme described below is adopted in the present application:

[0031] A control method of a water dispenser, applicable to a water dispenser, as shown in Figure 1 The water dispenser includes a water storage device 11 for storing water, a heating device 12 arranged in the water storage device 11 for heating the water in the water storage device 11, a water outlet pipeline 13 having a water pump 131 and an air exhaust device 132 arranged therein, and a temperature sensor 133 arranged at the water outlet of the water outlet pipeline 13 for detecting temperature and transmitting a temperature signal to a controller.

[0032] Figure 2 A flow chart of a control method of a water dispenser according to an embodiment of the present application, with reference to Figure 2 The water dispenser control method can include the following steps:

[0033] S21. Obtaining a water outlet instruction.

[0034] S22. Judging whether the boiling stage is reached when the water outlet instruction is obtained.

[0035] S23. Outputting an air exhaust instruction to make the air exhaust device perform air exhaust.

[0036] S24. Controlling the water pump to perform the water-out operation based on the water-out instruction, so that the water stored in the water storage device can be smoothly discharged through the water-out pipeline and / or the water pump.

[0037] As an exemplary embodiment, the water-out action can be performed based on the user instruction, and the water-out instruction can be obtained according to the user instruction; or the water-out action can be performed by detecting the water-receiving action, and the water-out instruction can be obtained according to the water-receiving action. For example, during the heating process of the water dispenser, when the boiling stage is reached, more bubbles are attached to the pipeline or the water pump. If the water-out operation is not performed at this time, it does not matter even if the pipeline is blocked. However, when the user needs to control the water-out of the water dispenser, the water bubbles in the water-out assembly cannot be discharged immediately because of the accumulation of water bubbles in the water-out assembly. Therefore, in order to identify the scenario of performing the above operation, the water-out instruction needs to be obtained.

[0038] After obtaining the water-out instruction, S22. Determine whether the boiling stage is reached when the water-out instruction is obtained. Because the water dispenser can produce bubbles not only when boiling, but also when heating to a threshold temperature and continuing to heat, and when heating to a threshold temperature and stopping heating for a period of time. Therefore, the boiling stage can be the heating stage when bubbles are attached to the water-out pipeline and / or the water pump. When the water dispenser does not reach the boiling stage, the bubbles attached to the water-out pipeline and / or the water pump of the water dispenser have little effect on the water-out effect, and in this case, the water-out pipeline and the water pump inside will not be blocked. When the water dispenser reaches the boiling stage, the problem of the water-out pipeline and / or the water pump being blocked by the bubbles attached to the water-out pipeline and / or the water pump will occur. Because in general, the user will usually receive water when the boiling stage is reached, and input the water-out instruction, so there will be a problem of the water-out pipeline and / or the water pump being blocked by the bubbles attached to the water-out pipeline and / or the water pump when the boiling stage is reached.

[0039] Therefore, after obtaining the water outlet instruction, it is necessary to determine whether the boiling stage is reached. After obtaining the water outlet instruction, when it is determined that the boiling stage is reached, it means that there are many bubbles attached to the water outlet pipeline or the water pump, which may affect the water outlet effect. Then, the air exhaust instruction is executed to make the air exhaust device exhaust air. After the air exhaust operation is performed, the bubbles attached to the water outlet pipeline or the water pump are exhausted, and the water outlet pipeline is unobstructed. Then, the water pump is controlled based on the water outlet instruction to perform the water outlet operation, so that the water stored in the water storage device can be smoothly discharged through the water outlet pipeline and / or the water pump. When it is not determined that the boiling stage is reached, the water outlet pipeline and / or the water pump are not attached with bubbles, and there is no obstruction. At this time, the water pump is directly controlled based on the water outlet instruction to perform the water outlet operation, so that the water stored in the water storage device can be smoothly discharged through the water outlet pipeline and / or the water pump.

[0040] When it is not determined that the boiling stage is reached after obtaining the water outlet instruction, the water outlet pipeline and / or the water pump are not attached with bubbles, and there is no obstruction. At this time, step S24 is directly entered. The water pump is controlled based on the water outlet instruction to perform the water outlet operation, so that the water stored in the water storage device is discharged through the water outlet pipeline and / or the water pump.

[0041] Based on the control method of the water dispenser, after obtaining the water outlet signal, it is determined whether the boiling stage is reached. When the boiling stage is reached, the air exhaust instruction is output to make the air exhaust device exhaust air. Then, the water pump is controlled based on the water outlet instruction to perform the water outlet operation, so that the water in the water storage device is smoothly discharged. When the boiling stage is not reached, the water pump is directly controlled based on the water outlet instruction to perform the water outlet operation, so that the water in the water storage device is smoothly discharged. In this way, when the water dispenser is in the boiling stage, the accumulation of bubbles in the pipeline is avoided, the water outlet pipeline and the water path are not blocked, and the problem of ensuring the smoothness of the water outlet path when the water dispenser is in the boiling stage is solved.

[0042] For example, the water dispenser generates bubbles when the boiling stage is reached. The boiling stage can be, for example, a stage in which the water temperature in the water storage device reaches the boiling point and the heating device is in the heating state. As an example, it can be a stage in which the boiling point at the local altitude is reached. For example, the boiling point can be any temperature value between 90°C and 100°C, which is collected according to the local altitude. In actual use, for the case where the user selects water outlet when the water temperature in the water storage device reaches the boiling point and the heating device is in the heating state: it is determined whether the water temperature in the water storage device reaches the boiling point when the water outlet instruction is obtained, and whether the heating device is in the heating state; when the water temperature reaches the boiling point and the heating device is in the heating state, it is determined that the boiling stage is reached, and the air exhaust instruction is output to make the air exhaust device exhaust air. Then, the water pump is controlled based on the water outlet instruction to perform the water outlet operation.

[0043] For example, the boiling stage can also be a stage in which the water temperature in the water storage device reaches over-boiling point and the heating device stops heating. After the water dispenser reaches the boiling stage and stops heating for a preset time interval, the water temperature will gradually decrease, and in the process of temperature decrease, the bubbles attached to the water outlet pipeline and / or the water pump will gradually decrease with the decrease of temperature. Therefore, it can be considered that after reaching the boiling point and stopping heating for a preset time interval, the bubbles attached to the water outlet pipeline and / or the water pump will decrease to a state in which they have less effect on water outlet. In addition, due to different heating efficiency, heat dissipation efficiency and residual heat of the heating device of different water dispensers, some water dispensers may have slower temperature decrease, and the water temperature may be relatively high after reaching the preset time interval, and the bubbles attached to the water outlet pipeline and / or the water pump may also be relatively more. Therefore, whether the exhaust is needed can also be determined by the water temperature value when the water outlet instruction is obtained.

[0044] Specifically, it is determined whether the water temperature in the water storage device reaches over-boiling point and whether the heating device is in a state of stopping heating when the water outlet instruction is obtained. When the water temperature reaches over-boiling point and the heating device is in a state of stopping heating, it is determined whether the time interval between the time when the water outlet instruction is obtained and the time when the water temperature reaches boiling point or the time when the heating device stops heating is less than a preset time interval and / or whether the water temperature is greater than a preset temperature value when the water outlet instruction is obtained. When the time interval is less than the preset time interval and / or the water temperature is greater than the preset temperature value, the exhaust instruction is output. Optionally, the preset time interval can be 2-6 minutes, and the preset temperature value can be any temperature value less than 95℃.

[0045] For example, during the heating process, when the water temperature is about to reach the boiling point, even if the boiling point is not reached, there will be a situation that a large number of bubbles are generated to affect the water outlet effect. Therefore, the boiling stage can also be a situation in which the water temperature in the water storage device is in the range of BP-N to BP. Wherein, BP is the boiling point, and N is any temperature value greater than zero, which is determined by factors such as ambient temperature and heat dissipation rate of the water dispenser. For example, BP is 100℃ and N is 5℃, and the range of BP-N to BP is 95℃-100℃. Optionally, the boiling point can also be the boiling temperature for making tea or brewing coffee.

[0046] In this way, the problem of ensuring the smoothness of the water outlet path when the water dispenser is in the boiling stage is solved.

[0047] For example, the exhaust device can be a heating pipe, a vacuumizing device, or a blowing device. As an example, the exhaust device is a heating pipe, which is described as follows:

[0048] Upon receiving the water outlet command and determining that the boiling stage has been reached, step S23 is initiated by outputting an exhaust command; the heating element generates at least one water vapor based on the exhaust command, and the vapor travels along the water outlet pipe as follows: Figure 1 The water flows in the direction indicated by the arrow. Since a large proportion of water produces steam, the water intake needs to be reduced to prevent a negative user experience. This optimal water intake can be called the preset amount. Therefore, after issuing the venting command, the heating element generates at least one stream of steam based on the venting command, which flows through the outlet pipe to expel any air bubbles adhering to it. Each time, the amount of steam is less than the preset amount to prevent a negative user experience. This method avoids the accumulation of air bubbles in the pipes during the boiling stage of the water dispenser, preventing blockages in the outlet pipe and water path, thus solving the problem of ensuring smooth water flow during the boiling stage.

[0049] Furthermore, as an exemplary embodiment, after an exhaust command is output, the instantaneous heating pipe heats up based on the exhaust command. When the instantaneous heating pipe reaches a preset temperature, in order to ensure that the amount of water vapor produced each time is less than a preset amount, the controller controls the water pump to pump water into the heating pipe in a jogging manner to generate water vapor. To generate water vapor, the preset temperature can be a temperature greater than or equal to the boiling point.

[0050] Furthermore, as an exemplary embodiment, the temperature of the instant heating pipe gradually decreases during the process of heating water to vaporize it into water vapor. When the temperature of the instant heating pipe is lower than the preset temperature, the water pump is controlled to stop pumping water to the instant heating pipe and the instant heating pipe is controlled to heat. When the temperature of the instant heating pipe is heated to the preset temperature, the water pump is controlled to pump water to the heating pipe in a jogging manner.

[0051] Furthermore, to ensure that the amount of water vapor produced each time is less than a preset amount, thus preventing a negative user experience, the controller can control the water pump to pump water to the heating element in a jogging manner. Optionally, this jogging method can involve pumping small amounts of water multiple times. As an exemplary embodiment, the controller controls the water pump to pump water at a preset power and for a preset pumping time. The preset power can be 10% to 30% of full power, and the preset pumping time can be 100ms to 300ms. Based on this method, the amount of water vapor is controlled, preventing a negative user experience.

[0052] In some embodiments of the present invention, the water dispenser may include a water storage device; a heating device disposed in the water storage device; a water outlet pipe, in which a water pump and an exhaust device are disposed, wherein the exhaust device, when triggered, exhausts gas from inside the water outlet pipe and / or the water pump; the water dispenser further includes a processor, a memory, and execution instructions stored in the memory, wherein the execution instructions are configured to enable the control method of the water dispenser described in any one of the above embodiments when executed by the processor.

[0053] In some embodiments of the present application, the water dispenser comprises a water storage device for storing water; a heating device arranged in the water storage device for heating the water in the water storage device; a water outlet pipeline, in which a water pump and an exhaust device are arranged;

[0054] Optionally, taking the heating pipe as an example, the heating pipe is arranged in the water outlet pipeline, under the indication of the exhaust instruction, the heating pipe is heated, and the water pump pumps water to the heating pipe in a jog mode. Based on the above structure and control method, the problem that the waterway and the water pump are blocked and water cannot be immediately and smoothly discharged due to the accumulation of bubbles in the pipeline can be solved.

[0055] Based on the above control process, in order to facilitate the understanding of the control process, the control scheme can be described by taking the following specific embodiments as exemplary embodiments:

[0056] When the user presses the water outlet key, the controller reads the temperature of the heating device through the temperature sensor. If the temperature of the heating device is less than 98℃, the above exhaust operation is not performed.

[0057] If the liquid in the water storage device is boiled, it is determined whether the standing time exceeds 5 minutes. If the standing time exceeds 5 minutes, the exhaust operation is not performed.

[0058] If the standing time does not exceed 5 minutes, the exhaust operation is performed before the water outlet operation is executed.

[0059] For the control process of the exhaust mode, the following embodiments can be taken as examples for description:

[0060] The temperature of the instant heating pipe is determined through the temperature sensor of the water outlet.

[0061] When the temperature of the instant heating pipe is 100℃, the water pump is used to pump water to the instant heating pipe at a power of 20% for 200ms.

[0062] When the temperature of the instant heating pipe is less than 100℃, the temperature of the instant heating pipe is heated to 100℃.
