In this embodiment, the refrigeration control method of the water dispenser is applied to the water dispenser of the above embodiment.

The refrigeration control method of the water dispenser comprises the following steps:

step S10, acquiring a first temperature currently detected by the temperature detection device;

in the embodiment, after the water dispenser is powered on and started, the temperature detection device is powered on to detect the current first temperature of cold water in the cold tank in real time, and the detection of the first temperature by the temperature detection device is real-time detection, wherein the first temperature is the temperature of cold water in the inner cavity of the cold tank close to the bottom and is also the temperature of cold water in a water outlet channel close to a water faucet of the water dispenser; the temperature detection device can be a temperature sensing tube, a patch type sensor, a temperature probe, an infrared temperature sensor or an instrument with a temperature detection function and the like.

During the period that the temperature detection device detects the current first temperature in real time, the control unit acquires the first temperature detected in the temperature detection device in real time by means of electrically connected data transmission, wherein the control unit can be an integrated circuit control chip such as an IC chip and the like, such as an IC9 system control chip, for controlling the operation of the equipment.

Furthermore, the temperature detection device is arranged near a water faucet of the water dispenser, so that the water consumption of a user is increased, the consumption of cold water in the cold tank is large, and the temperature of the cold water in the cold tank is increased quickly, so that the water consumption of the user can be detected when the user uses water by detecting the first temperature through the temperature detection device. When a user uses water, the first temperature can represent the water consumption of the user when the user uses boiled water at a tap of the water dispenser, the water consumption is large when the first temperature is large, and the water consumption is small when the first temperature is small; when the user does not use water, namely the cold water in the cold tank is static, the first temperature represents the temperature of the cold water stored in the cold tank, the temperature of the cold water in the cold tank is high when the first temperature is high, and the temperature of the cold water in the cold tank is low when the first temperature is low. Therefore, the first temperature of the cold water in the cold tank is detected through the temperature detection device, the temperature change of the cold water in the cold tank when the cold water is static is monitored constantly, and the water temperature in the cold tank is judged along with the different temperature changes of the water consumption of a user, so that whether the compressor and the pump are turned on for refrigerating and circulating the cold water in the cold tank is judged.

Step S20, detecting whether the first temperature is higher than a first preset temperature;

the first preset temperature is a temperature boundary point whether to start refrigeration of the water dispenser, that is, whether to enter a refrigeration mode, and is generally 6 ℃, and is set according to conditions of water dispenser devices of different models or a temperature value set by a user for the water dispenser, which is not specifically limited in this embodiment. In this embodiment, the cooling mode is defined as the mode in which the compressor and the pump are operated simultaneously to make the temperature of the cold water reach a certain temperature quickly.

In this embodiment, after obtaining the first temperature of the cold water in the cold tank, the control unit obtains a first preset temperature stored in the storage unit, determines whether the value of the first temperature is greater than the value of the first preset temperature, and determines whether the water dispenser should turn on the compressor and the pump to refrigerate and circulate the cold water in the cold tank by determining whether the first temperature is greater than the first preset temperature. If the first temperature is higher than the first preset temperature, the water temperature in the cold tank is higher or the water consumption of a user is large, and the cold water stored in the cold tank is not enough, the cold tank enters a refrigeration mode, and a compressor and a pump are started to start refrigeration; if the first temperature is lower than the first preset temperature, the water temperature in the cold tank is lower or the water consumption is low, and the cold water stored in the cold tank is enough to be used, the compressor and the pump are kept closed continuously.

For example, the preset first preset temperature is 6 ℃, when the first temperature of the obtained cold water in the cold tank is 4 ℃, the first temperature is higher than the first preset temperature, and the compressor and the pump are started; and when the first temperature of the obtained cold water in the cold tank is 4 ℃, the first temperature is less than or equal to a first preset temperature, and the compressor and the pump are continuously kept closed.

And step S30, if the first temperature is higher than the first preset temperature, controlling a compressor of the refrigerating device and a pump of the cold water circulating device to start.

In this embodiment, the control unit obtains a first temperature of cold water in the cold tank, and after detecting whether the first temperature is greater than a first preset temperature, obtains a corresponding instruction according to a result detected by the control unit, and controls the corresponding device to execute an operation corresponding to the control instruction, such as controlling the compressor to start or close. And if the first temperature is higher than the first preset temperature, entering a refrigeration mode, and controlling a compressor of the refrigeration device and a pump of the cold water circulating device to start refrigeration and start circulating cold water in the cold tank respectively.

The compressor is started, when refrigeration is carried out, the refrigerant is compressed into high-temperature high-pressure gas after the compressor is started, the high-temperature high-pressure gas flows into the condenser, after the condenser radiates heat outwards, high-temperature high-pressure liquid refrigerant is formed in the condenser, the high-temperature high-pressure liquid refrigerant flows through the capillary tube, the liquid refrigerant is reduced in pressure through throttling of the capillary tube, normal-temperature normal-pressure liquid refrigerant is formed, the normal-temperature normal-pressure liquid refrigerant flows into the evaporator to be evaporated, the temperature of the whole evaporator is rapidly reduced, heat exchange is carried out on the refrigerant between the evaporator and water in the cold tank, the heat of the water in the cold tank is absorbed, and therefore the temperature of.

And starting a pump of the circulating device while starting the compressor, starting the pump to circulate cold water in the cold tank, pumping the cold water in the cold tank out of a water inlet pipe of the pump by the pump, and flowing back to the cold tank from a water outlet pipe of the pump after flowing through the pump. Compared with the heat conduction mode when water is static, the purpose of turbulent flow heat transfer is achieved, and the refrigeration effect is improved. The water dispenser is additionally provided with the cold water circulating device, so that the problem of a single heat conduction mode between an evaporator and cold water in the prior industry is solved, and when refrigeration is carried out, a pump of the cold water circulating device continuously circulates the cold water in the cold tank, so that the water dispenser not only has the most basic conduction heat transfer, but also carries out turbulent flow on the water in the cold tank, the heat transfer effect is improved, and the refrigeration time can be shortened by 50%. Furthermore, due to the circulation of the cold water in the cold tank by the cold water circulating device, the temperature of the cold water at different positions in the cold tank is basically consistent after a period of refrigeration and cold water circulation, and the problem of uneven temperature of the cold water is solved.

The refrigeration control method for the water dispenser provided by the embodiment comprises the steps of firstly obtaining the first temperature currently detected by the temperature detection device, then detecting whether the first temperature is higher than a first preset temperature, and finally if the first temperature is higher than the first preset temperature, controlling the compressor of the refrigerating device and the pump of the cold water circulating device to start, starting the cold water in the circulating cold tank by starting the compressor to run the refrigerating and the pump of the cold water circulating device, entering a refrigerating mode, when refrigerating, the pump of the cold water circulating device continuously circulates the cold water in the cold tank, so that the water dispenser not only has the most basic heat conduction, but also carries out turbulent flow on the water in the cold tank, thereby improving the heat transfer effect, meanwhile, the temperature of cold water at different positions in the cold tank is basically consistent, so that the problems of poor heat transfer effect and non-uniform cold water temperature are solved.

Based on the first embodiment, a second embodiment of the refrigeration control method for a water dispenser of the present invention is provided, in this embodiment, after step S30, the method further includes:

Wherein the ice storage mode is defined as closing a pump of the cold water circulating device to store ice; the economized mode is defined as continuing to keep the compressor and pump running to refrigerate and circulate the chilled water to maintain the chilled water temperature between a certain range for use by the user.

Specifically, the same as the first temperature, when the user uses water, the second temperature can represent the water consumption of the user when the water is boiled and used by the water dispenser tap, the water consumption is large when the value of the second temperature is large, and the water consumption is small when the value of the second temperature is small; when the user does not use water, namely the cold water in the cold tank is static, the value of the second temperature indicates that the temperature of the cold water stored in the cold tank is high, the value of the second temperature is high, the temperature of the cold water in the cold tank is high, and the value of the second temperature is low, the temperature of the cold water in the cold tank is low. The second temperature of the cold water in the cold tank is detected through the temperature detection device, the temperature change of the cold water in the cold tank is monitored constantly when the cold tank is static, the water temperature in the cold tank is judged along with the temperature change of the difference of the water consumption of a user, the water temperature in the cold tank is not consistent with the step of obtaining the first temperature, and the step of obtaining the second temperature is used for judging whether the cold tank enters an energy-saving mode or an ice storage mode.

B, detecting whether the second temperature is higher than a second preset temperature, wherein the second preset temperature is higher than the first preset temperature;

the second preset temperature is a temperature dividing point between the ice storage mode and the energy saving mode, the second preset temperature is generally 7 ℃, and the second preset temperature is set according to conditions of different models of water dispenser equipment, and is not specifically limited in this embodiment. In this embodiment, the ice storage mode is defined as the state in which the pump stops working, the compressor continues to operate, and the ice storage mode is completed under the control of a time parameter, wherein the time parameter starts to calculate time based on the stop of the pump, and when the set time parameter is reached after the pump is turned off, the compressor stops operating, and the ice storage mode is completed, wherein the time parameter can also be adjusted according to different water dispenser devices or the thickness of an ice layer to be reached.

In this embodiment, after the control unit obtains the second temperature, a second preset temperature preset in the storage unit is obtained, and the second temperature is compared with the second preset temperature to determine whether the second temperature is greater than the second preset temperature. And judging whether the water dispenser enters an ice storage mode or an energy-saving mode by judging whether the second temperature is higher than a second preset temperature. If the second temperature is higher than the second preset temperature, the water temperature in the cold tank is relatively high or the water consumption of a user is relatively large, and the water dispenser enters an ice storage mode; if the second temperature is lower than the second preset temperature, the water temperature in the cold tank is relatively low or the water consumption is relatively low, so that the water dispenser enters an energy-saving mode.

And c, if the second temperature is higher than the second preset temperature, closing the pump when the third temperature currently detected by the temperature detection device is lower than the third preset temperature, wherein the third preset temperature is lower than the second preset temperature.

The third preset temperature is a sign of entering the ice storage mode, is generally 2 ℃, and is set according to the conditions of different models of water dispenser devices, and is not particularly limited in this embodiment.

In this embodiment, if the temperature detection device detects that the second temperature of the cold water in the cold tank is greater than the second preset temperature, which indicates that the temperature is sufficiently low, the ice storage mode can be entered, and then the temperature detection device starts to detect the third temperature, and enters the ice storage mode. If the third temperature of the cold water in the current cold tank is detected to be lower than the third preset temperature in real time, the water dispenser is controlled to refrigerate until the temperature in the cold tank reaches the third preset temperature, the pump is turned off to store ice in the cold tank, and a layer of thick ice is stored on the inner wall of the cold tank close to the evaporator, so that the ice storage and cold accumulation effects are achieved, a large amount of water for users is used, the amount of cold water stored in the water dispenser is increased, and the problem that the temperature of the whole outlet water of the water dispenser is high is solved.

In the refrigeration control method for the water dispenser provided by this embodiment, by obtaining a second temperature currently detected by the temperature detection device, it is detected whether the second temperature is greater than a second preset temperature, where the second preset temperature is greater than the first preset temperature, and if the second temperature is greater than the second preset temperature, when a third temperature currently detected by the temperature detection device is less than a third preset temperature, the pump is turned off, where the third preset temperature is less than the second preset temperature, and the current water temperature of the cold tank is detected to determine that the water dispenser enters an ice storage mode or an energy saving mode, so that the water dispenser is accurately controlled to enter the ice storage mode, and the accuracy of temperature control is improved.

Based on the second embodiment, a third embodiment of the refrigeration control method for a water dispenser of the present invention is provided, in this embodiment, after step c, the method further includes:

and d, if the duration time after the pump is closed reaches a preset duration time, closing the compressor.

The preset time length is a time parameter in the ice storage mode mentioned in the second embodiment, that is, the preset time length is calculated based on the stop of the pump, when the preset time length is reached after the pump is turned off, the compressor stops operating, the ice storage mode is completed, the preset time length can be adjusted according to different water dispenser devices or the thickness of an ice layer to be reached, the preset time length is generally 60 minutes, and the present embodiment is not particularly limited.

In this embodiment, after entering the ice storage mode to start storing ice, after the pump is turned off, that is, after the pump stops working, the control unit starts timing to make the compressor continue to operate for a preset time period to stop refrigerating, so as to store a layer of thick ice in the cold tank to meet the requirement of a user on a large amount of water.

According to the refrigeration control method of the water dispenser, the compressor is closed if the duration time after the pump is closed reaches the preset duration time, the control unit times the ice storage time, the compressor is controlled to operate for a period of time to store a layer of thick ice in the cold tank, so that the refrigeration ice storage time of the water dispenser is accurately controlled, the accuracy of time control is improved, the effects of storing ice and storing cold are achieved, the cold water quantity of a product is improved, a large amount of water for a user is met, and the problem that the temperature of the whole outlet water of the water dispenser is high is solved.

Based on the second embodiment, a fourth embodiment of the refrigeration control method for a water dispenser of the present invention is provided, in this embodiment, after step b, the method further includes:

step e, if the second temperature is less than or equal to the second preset temperature, detecting whether the second temperature is less than a fourth preset temperature, wherein the fourth preset temperature is greater than the third preset temperature, and the fourth preset temperature is less than the first preset temperature;

the second preset temperature is a temperature dividing point between an ice storage mode and an energy saving mode, the second preset temperature is generally 7 ℃, and the second preset temperature is set according to the conditions of different types of water dispenser equipment, and is not specifically limited in the embodiment; the fourth preset temperature is a temperature node at which the operation in the energy-saving mode is finished, and the fourth preset temperature is generally 4 ℃. The energy-saving mode is defined as that when the temperature of cold water in the cold tank is relatively low or the water consumption of a user is low, the temperature of the cold water is controlled to be in a state that the water temperature is low enough (4 ℃ can be set to be switched off and 6 ℃ can be set to be switched on) but the water dispenser cannot run for a long time, so that the energy consumption of the water dispenser is reduced to the maximum extent.

In this embodiment, after the control unit obtains the second temperature currently detected by the temperature detection device, if the second temperature is less than or equal to the second preset temperature, it is continuously determined whether the second temperature is less than a fourth preset temperature. If the temperature is lower than the fourth preset temperature, the compressor and the pump are closed, and the energy-saving mode is exited; and if the temperature is higher than the fourth preset temperature, the compressor and the pump are continuously kept running for refrigeration. For example, judging whether the second temperature of the cold water in the current cold tank is less than 4 ℃, if so, closing the compressor and the pump, and exiting the energy-saving mode; if the temperature is higher than 4 ℃, the compressor and the pump are continuously kept running for refrigerating until the second temperature reaches 4 ℃.

And f, if the second temperature is lower than the fourth preset temperature, closing the compressor and the pump.

In this embodiment, if the second temperature detected by the temperature detection device is less than or equal to the second preset temperature, the water dispenser is controlled to enter the energy saving mode, that is, the compressor and the pump are started to continue to operate, refrigeration and circulation of the cold water in the cold tank are started, and when the second temperature of the cold water in the cold tank reaches the fourth preset temperature, the compressor and the pump are turned off, the energy saving mode is exited, and refrigeration and circulation of the cold water in the cold tank are stopped. Further, when the second temperature in the cold tank rises to the first preset temperature again, the compressor and the pump are controlled to start to refrigerate, and therefore the temperature of the cold water is kept between the first preset temperature and the fourth preset temperature.

It can be understood that, or after the water dispenser completes the refrigeration mode and the ice storage mode, the compressor and the pump start to stop running, the cold water in the tank is in a state of ice-water mixing, and the thick ice layer in the cold tank also stores enough cold energy. At the moment, the compressor and the pump are controlled to be switched on between the second temperature and the first preset temperature and the second preset temperature, the compressor and the pump are switched off when the temperature is cooled to the second temperature and reaches the fourth preset temperature or below, and the energy-saving mode is entered; and the compressor and the pump are closed when the second temperature rises to a fourth preset temperature, and the energy-saving mode is exited. When the water consumption of the user is low, the water dispenser is kept to operate between the fourth preset temperature and the low-temperature interval of the first preset temperature.

It can be understood that when the water consumption of the user is suddenly increased to raise the second temperature to or above the second preset temperature, the water dispenser is controlled to exit the energy-saving mode, enter the refrigeration mode and the ice storage mode, and then start a new cycle of circulation of the refrigeration mode, the ice storage mode and the energy-saving mode.

According to the refrigeration control method for the water dispenser, provided by the embodiment, whether the second temperature is lower than a fourth preset temperature is detected if the second temperature is lower than or equal to the second preset temperature, wherein the fourth preset temperature is higher than the third preset temperature and lower than the first preset temperature, if the second temperature is lower than the fourth preset temperature, the compressor and the pump are turned off, the water temperature of the current cold tank is detected to judge that the water dispenser enters the energy-saving mode or exits the energy-saving mode, so that the water dispenser is accurately controlled to enter the energy-saving mode and exit the energy-saving mode, the accuracy of the advance and retreat energy-saving mode is improved, the state that the water dispenser runs for a long time without being cooled in the cold tank is further controlled, and the energy consumption of the water dispenser is reduced to the maximum extent.
