[0022] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0023] The following describes a refrigeration system and a drinking water device according to an embodiment of the present invention with reference to the accompanying drawings.

[0024] The drinking water equipment in the present invention includes a variety of water treatment functions, such as refrigeration, ice making, heating, filtering, etc. This embodiment describes the refrigeration system of the drinking water equipment with the refrigeration and ice making function. Figure 1 In this embodiment, the refrigeration system 1000 of the drinking water equipment includes a temperature sensor 100, a refrigeration device 200 and a control device 300.

[0025] Among them, the temperature sensor 100 is arranged on the base of the drinking water equipment, and is used to detect the temperature information of the environment in which the drinking water equipment is located; the refrigeration device 200 includes a compressor 10, and the compressor 10 is arranged on the base; the control device 300 is respectively connected to the temperature sensor and the compressor 10, and is used to control the compressor 10 to perform an ice-making operation at a first operating frequency according to the temperature information, and after the ice-making operation is completed, if no cold water or ice-taking instruction is received within a first preset time period, the compressor 10 is controlled to operate at a second operating frequency, wherein the second operating frequency is less than the first operating frequency.

[0026] Specifically, the drinking water device is provided with a base, which is used to carry other devices on the drinking water device, and the base is in direct contact with the external environment. Therefore, in this embodiment, a temperature sensor 100 is directly provided on the base, and the temperature information of the environment in which the drinking water device is located can be accurately obtained. In this embodiment, the refrigeration device 200 includes a compressor 10, and the compressor 10 type is a variable frequency compressor 10. The compressor 10 is also provided on the base. It should be noted that since the compressor 10 is heavy, it is provided on the base to increase the stability of the base. The control device 300 is respectively connected to the temperature sensor 100 and the compressor 10, and can obtain the temperature information of the environment collected by the temperature sensor 100, and then control the compressor 10 to run the ice-making operation based on the temperature information, and after the compressor 10 completes the ice-making operation, if no cold water taking instruction or ice taking instruction is received within the first preset time length, the compressor 10 is controlled to run at a second operating frequency, and the second operating frequency can be the operating frequency corresponding to the energy-saving operation mode.

[0027] More specifically, after the control device 300 obtains the temperature information of the environment, it can determine the ice making parameters and ice removing parameters according to the temperature information. The ice making parameters and ice removing parameters can be used to control the ice making mode of the refrigeration device. In this embodiment, the first operating frequency corresponding to the first ice making mode is used to control the refrigeration device. It should be noted that when the temperature information of the environment is high, the heat exchange is relatively poor. Therefore, when making the same weight of ice, the time spent on ice making at high temperature is longer than the time spent on ice making at normal temperature. On the contrary, the time spent on ice removing at high temperature is shorter than the time spent on ice removing at normal temperature. The opposite is true in a low temperature environment. It should be noted that the present embodiment determines the ice making mode according to the temperature information of the environment, specifically to ensure that the weight of a single ice particle in different environments is within a certain range, that is, to ensure that the size and weight of the ice particles are uniform and to improve the aesthetics of the ice particles. In the process of running the first ice making mode, the generated ice particles will be swept into the ice storage bin for storage. When the ice storage bin is full of ice particles, it can be determined that the ice making operation is completed, and then the timing operation is performed. When the timing reaches the first preset time and the drinking water device does not receive any instructions for taking ice or cold water, the refrigeration device can be controlled to operate at a second operating frequency corresponding to the second ice-making mode, wherein the second ice-making mode can be an ECO (Ecology Conservation Optimization) mode to control the refrigeration device to operate in an energy-saving manner and reduce energy consumption. It should be noted that the cold water taking instruction and the ice taking instruction can be generated by a control screen set on the drinking water device, or by infrared signals, radio frequency signals, etc. It should be noted that the second operating frequency is less than the first operating frequency.

[0028] In some embodiments of the present invention, the control device 300 is further configured to: when the compressor 10 is operating at the second operating frequency, if a cold water taking instruction or an ice taking instruction is received, control the compressor 10 to operate at the first operating frequency.

[0029] Specifically, when the control device 300 is controlling the compressor 10 to operate at the second operating frequency, if no cold water or ice instruction is received, the control device 300 will continue to control the compressor 10 to operate at the second operating frequency to reduce energy consumption. During this process, if the drinking water equipment receives a cold water or ice instruction, the control module 30 will control the compressor 10 to switch from the second operating frequency to the first operating frequency to meet the user's usage needs as soon as possible.

[0030] In some embodiments of the present invention, Figure 2 As shown, the refrigeration device 200 also includes: an ice making bin 12, a condenser 11, a cold water tank 13 and an ice storage bin 14, wherein the condenser 11 is arranged in the ice making bin 12; the cold water tank 13 is arranged below the ice making bin 12, and is used to collect cold water generated when the condenser 11 is in operation; the inlet of the ice storage bin 14 is arranged opposite to the outlet of the ice making bin 12, and is used to store ice cubes generated when the refrigeration device is in operation.

[0031] In addition, the ice making refrigerator 12 includes an ice sweeping module 121 and an ice storing module 122. The ice sweeping module 121 is arranged between the condenser 11 and the ice storing module 122, and the ice sweeping module 121 can rotate back and forth around the condenser 11. When the ice sweeping module 121 rotates back and forth, the ice cubes in the ice storing module 122 are sent to the ice storage bin 14 through the outlet of the ice making refrigerator 12 for storage.

[0032] Specifically, a through hole is also provided at the bottom of the ice storage module 122 for guiding the cold water generated by the condenser 11 during ice making and refrigeration to the cold water tank 13. The ice sweeping module 121 can rotate around the axis of the condenser 11. When making ice and refrigerating, the ice sweeping module 121 can be in a Figure 2 The position shown in the figure, when defrosting, the ice sweeping module 121 can rotate 180 degrees counterclockwise and be located on the upper side of the condenser 11, leaving space above the condenser 11 for the ice sweeping module 121 to rotate. After the condenser 11 is defrosted, the ice sweeping module 121 rotates 180 degrees clockwise again, and sweeps the ice particles shed in the ice making bin 12 toward the outlet of the ice making bin 12, so as to be swept into the ice storage bin 14 through the outlet of the ice making bin 12.

[0033] In this embodiment, a sensor is provided on the ice storage bin 14 , and the sensor is used to detect the ice storage state in the ice storage bin 14 .

[0034] Specifically, a sensor (not shown in the figure) is provided on the ice storage bin 14. For example, the sensor may be an infrared sensor, which is used to detect the ice storage state in the ice storage bin 14. It should be noted that the sensor may be provided at the full ice position of the ice storage bin 14, and is used to detect whether there are ice particles at the full ice position. If detected, it is determined that the ice storage state in the ice storage bin 14 is a full ice state, otherwise it is determined that the ice storage state in the ice storage bin 14 is a not full ice state.

[0035] In this embodiment, the control device 300 is further used to determine that the ice making operation is completed when the ice storage state is a full ice state and the cold water temperature of the cold water tank 13 is lower than a second preset temperature.

[0036] Specifically, in this embodiment, another temperature sensor is further provided in the cold water tank 13, and the temperature sensor is used to detect the temperature of the cold water in the cold water tank 13. The control device 300 can judge whether the ice making operation is completed according to the cold water temperature combined with the ice storage state. More specifically, when the ice storage state is a full ice state and the cold water temperature in the cold water tank 13 is less than the second preset temperature, it can be determined that the ice making operation has been completed, that is, ice making has been completed at present.

[0037] In some embodiments of the present invention, the control device 300 is also used to: before obtaining the temperature information of the environment in which the drinking water equipment is located through the temperature sensor, control the refrigeration device to perform a refrigeration operation, then obtain the cold water temperature in the cold water tank 13, and when the cold water temperature is less than or equal to the first preset temperature, control the refrigerator 12 to perform defrosting processing.

[0038] Specifically, before obtaining the temperature information of the environment in which the drinking water device is located through the temperature sensor, in order to ensure that there are no extra ice particles in the ice making refrigerator 12 to affect ice making, this embodiment will first perform ice-defrosting before the condenser 11 performs refrigeration and ice making. The specific ice-defrosting process includes: first, the control device 300 controls the refrigeration device to perform refrigeration operation, that is, the compressor 10, the refrigerant solenoid valve and other refrigeration-related devices will be turned on, and then the temperature of the cold water in the cold water tank 13 is obtained, and when the cold water temperature is less than or equal to the first preset temperature, the ice making refrigerator 12 is controlled to perform ice-defrosting. Among them, the cold water temperature is controlled to be less than or equal to the first preset temperature so that the cold water will not have a significant impact on the ice making operation. When the cold water temperature is high, it will cause the ice cubes made in the ice making operation to melt easily, causing the ice cubes to stick together, and the energy consumption of ice making will also increase. In this embodiment, the deicing process can be implemented by using the ice sweeping module 121. Specifically, the ice sweeping module 121 can be controlled to flip 180 degrees and maintain for 5 seconds to allow ice particles to fall into the ice making bin 12, and then the ice sweeping module 121 can be controlled to reset. During the resetting process, the ice sweeping module 121 can move the ice particles that have fallen into the ice making bin 12 to the ice storage bin 14 for storage. It should be noted that the deicing process in this embodiment can be performed multiple times, for example, twice, to ensure complete deicing. In addition, the time that the ice sweeping module 121 is maintained during the above deicing process can be specifically determined according to the ambient temperature. The higher the ambient temperature, the shorter the maintenance time, and the lower the ambient temperature, the longer the maintenance time.

[0039] In this embodiment, the control device 300 is further configured to: before controlling the refrigeration device to perform a refrigeration operation, control the refrigeration device to be in a shutdown state for a second preset time period.

[0040] Specifically, before performing the de-icing operation, when the drinking water device is powered on for refrigeration, the control device 300 controls the refrigeration device to be in a shutdown state for a second preset time before entering the working state. The purpose is to prevent the drinking water device from making a misjudgment. If the ice storage bin 14 is full of ice, and a misjudgment occurs at this time, causing the refrigeration device to continue making ice, and the ice particles produced are blocked during the storage process, it may cause the internal pressure of the compressor 10 to be unbalanced, resulting in abnormalities or tripping. Therefore, before controlling the refrigeration device to perform the refrigeration operation, the control device 300 of this embodiment will also control the refrigeration device to be in a shutdown state for a second preset time, wherein the second preset time may be 3 minutes. During these three minutes, the compressor, the refrigerant solenoid valve and other refrigeration-related devices are in a shutdown state.

[0041] In some embodiments of the present invention, the control device 300 is further used to control the refrigeration device to execute a heat preservation program when the ice storage bin 14 is full of ice and the cold water temperature of the cold water tank is lower than a third preset temperature.

[0042] Specifically, no matter the compressor is operated at the first operating frequency or the second operating frequency, during the operation, it is necessary to judge whether the ice making operation is completed, which can be judged specifically by the ice storage state of the ice storage bin 14 and the temperature of the cold water in the cold water tank 13. When the ice storage state is full of ice and the cold water temperature is less than the third preset temperature, the control device 300 can control the refrigeration state of the compressor to the heat preservation program. In this embodiment, the heat preservation program can be to control the operating speed of the refrigeration device to a preset speed, such as 500rpm, 1000rpm, etc., or to directly control the refrigeration device to shut down. Optionally, the third preset temperature in this embodiment is 6 degrees Celsius.

[0043] It should be noted that when the ice storage state is not full of ice or the temperature of the cold water in the cold water tank is greater than or equal to the third preset temperature, the control device 300 can control the refrigeration device to exit the insulation state and return to the normal execution state, that is, operate at the original operating frequency.

[0044] In summary, the refrigeration system of the drinking water device in the embodiment of the present invention can reduce the refrigeration power consumption and refrigeration cost of the drinking water device and improve the user experience.
