[0029] The refrigeration equipment in the embodiments of the present application includes refrigerators, freezers and other refrigeration equipment with ice-making mechanisms.

[0030] The present application first proposes a refrigeration equipment, such as Figure 1 shown Figure 1 is a schematic structural diagram of an embodiment of the refrigeration equipment of the present application. The refrigeration equipment of this embodiment includes: a box body 11, an inner liner 12, a air supply mechanism 13, an ice-making mechanism 14 and a cold storage mechanism 15. The inner liner 12 is arranged inside the box body 11. A freezer 16 is provided inside the inner liner 12. An air duct 17 is also formed between the box body 11 and the inner liner 12. An air outlet connecting the air duct and the freezer 16 is opened on the side wall of the inner liner 12; a part of the air supply mechanism 13 is arranged in the air duct 17 and a part is arranged in the freezer 16 and is arranged close to the air outlet. The air supply mechanism 13 conveys cold air to the freezer 16 through the air outlet; the ice-making mechanism 14 and the cold storage mechanism 15 are arranged in the freezer 16 and are arranged close to the air outlet; the cold storage mechanism 15 is in contact with the ice-making mechanism 14 to provide cold energy for the ice-making mechanism 14.

[0031] Among them, the ice-making mechanism 14 may include an ice-making box and a bracket for mounting the ice-making box on the inner liner 12; the ice-making box is provided with a receiving cavity for storing ice-making liquid.

[0032] Among them, the box body 11 is provided with a door body, and the door body is used to open and close the freezer compartment.

[0033] In this embodiment, the projection of the ice-making mechanism 14 on the side wall of the inner liner 12 where the air outlet is located is located below the air outlet, which can prevent the cold air introduced into the freezer compartment 16 from the air outlet from being blocked by the ice-making mechanism 14, improving the refrigeration effect of the freezer compartment 16; and the ice-making surface of the ice-making mechanism 14 is located above it. Therefore, this structure can also make the cold air introduced into the freezer compartment 16 flow through the ice-making surface of the ice-making mechanism 14 more, thereby accelerating the ice-making speed of the ice-making mechanism 14.

[0034] Among them, when the ice-making mechanism 14 is in a non-ice-making state, for example, when the ice-making of the ice-making mechanism 14 is completed or no ice-making liquid is loaded, the cold storage mechanism 15 stores cold using the cold air in the freezer compartment 16. The cold storage mechanism 15 can provide cold for the ice-making mechanism 14 when the ice-making mechanism 14 is making ice, thereby accelerating the ice-making speed of the ice-making mechanism 14.

[0035] Optionally, the cold storage mechanism 15 of this embodiment is arranged below the ice-making mechanism 14, which can reduce the influence of the ice or ice-making liquid exposed on the upper ice-making surface of the ice-making mechanism 14 on the cold storage mechanism 15; and the cold storage mechanism 15 is arranged in close contact with the ice-making mechanism 14, which can accelerate the cold transfer efficiency between the two.

[0036] Optionally, the cold storage mechanism 15 of this embodiment may include a cold storage pack filled with cold storage liquid. The cold storage pack has a simple structure and can reduce the occupied space of the freezer compartment 16.

[0037] In other embodiments, the cold storage mechanism can also be implemented by using a semiconductor cold storage module or the like.

[0038] Optionally, a heat conducting member can also be arranged between the cold storage mechanism 15 and the ice-making mechanism 14 to increase the cold transfer effect between the two, thereby accelerating the refrigeration efficiency of the ice-making mechanism 14.

[0039] Furthermore, the refrigeration device of this embodiment further includes a temperature sensor, which is arranged on the cold storage mechanism 15 and is used to collect the temperature information of the cold storage mechanism 15.

[0040] Further, the refrigeration device of this embodiment further includes a controller, which is connected to the temperature sensor and the air supply mechanism 13, and is used to control the operation of the air supply mechanism 13 by using the control method described below, so that the cold storage mechanism 15 can replenish cold energy in time, and can shorten the cold storage time of the cold storage mechanism 15, improve the cold storage utilization rate of the cold storage mechanism 15, reduce the energy consumption required for ice making, and improve the ice making efficiency of the ice making mechanism 14.

[0041] Optionally, the air supply mechanism 13 of this embodiment includes a compressor 131, a fan 132 and a wind direction adjustment mechanism 133; wherein, the compressor 131 is used to generate cold air and transmit it into the air duct 17; the fan 132 is arranged in the air duct 17 and is used to blow the cold air in the air duct 17 towards the air outlet; the wind direction adjustment mechanism 133 is arranged in the freezer 16 and is located at the air outlet, and is used to adjust the wind direction of the air outlet.

[0042] The controller is respectively connected to the compressor 131, the fan 132 and the wind direction adjustment mechanism 133, and controls the operation of the compressor 131, the fan 132 and the wind direction adjustment mechanism 133 to improve the intelligent degree of control of the refrigeration device.

[0043] The controller is also connected to the temperature sensor, and the controller obtains the temperature information of the cold storage mechanism 15 from the temperature sensor.

[0044] Optionally, the wind direction adjustment mechanism 133 includes a damper arranged at the air outlet of the freezer 16. The ice making mechanism 14 and the cold storage mechanism 15 are arranged at the air outlet, and the ice making mechanism 14 is located above the cold storage mechanism 15. The included angle (such as Figure 1 shown) of the damper with the axial direction of the air outlet in the second air supply mode is smaller than the included angle (such as Figure 2 shown) of the damper with the axial direction of the air outlet in the first air supply mode.

[0045] The damper can be an electric damper. The wind direction adjustment mechanism 133 can also be a baffle.

[0046] Optionally, the rotation speed of the compressor 131 in the first air supply mode and the second air supply mode is greater than the rotation speed of the compressor in the third air supply mode; and / or, the rotation speed of the fan in the first air supply mode and the second air supply mode is greater than the rotation speed of the fan in the third air supply mode. Wherein the air supply mode is the working mode of the air supply mechanism 13 when the cold storage mechanism 15 is in the non-cold storage mode and the ice making mechanism 14 is in the non-ice making mode.

[0047] Among them, the controller determines the second working state of the ice-making mechanism 14 based on the temperature information of the cold storage mechanism 15, and controls the air supply mechanism 13 to operate in the second air supply mode when the second working state is the ice-making state, so that the ice-making mechanism 14 can make ice quickly; the controller determines the first working state of the cold storage mechanism based on the temperature information, and in response to the first working state being the cold storage state, controls the air supply mechanism 13 to operate in the first air supply mode to enable the cold storage mechanism to store cold quickly.

[0048] Optionally, the refrigeration device of this embodiment further includes a detection component for detecting the door opening / closing information of the freezer compartment 16, which is connected to the controller. The controller obtains the door opening / closing information of the freezer compartment from this detection component to determine whether the user needs to enter the rapid ice-making mode / cold storage mode. The detection component can be arranged on the door body or other positions on the cabinet 11 close to the door body.

[0049] In response to the opening action of the freezer compartment 16, the controller determines that the user needs to enter the rapid ice-making mode / cold storage mode, and then determines the second working state of the ice-making mechanism 14 and the first working state of the cold storage mechanism 15 based on the temperature information of the cold storage mechanism 15.

[0050] In other embodiments, it is also possible to automatically determine whether the user needs to enter the rapid ice-making mode / cold storage mode by arranging sensors such as infrared sensors or pressure sensors. For example, the door opening / closing information can be obtained through infrared sensors or pressure sensors, or the mode selection operation information for the user can be directly obtained.

[0051] In other embodiments, there are multiple air outlets, which are respectively arranged corresponding to the refrigeration mechanism and the cold storage mechanism. The air supply mode of the air supply mechanism can be adjusted by switching the air outlet of the air outlet; or different air ducts can be set, and the rapid cooling of the ice-making mechanism and the cold storage mechanism can also be realized by switching the air ducts.

[0052] The present application further proposes a control method for a refrigeration device, which can be used for the above-mentioned refrigeration device, such as Figure 3 shown Figure 3 is a schematic flowchart of an embodiment of the control method of the refrigeration device of the present application. The control method of this embodiment can be used for the above-mentioned refrigeration device, and specifically may include the following steps:

[0053] Step S21: Obtain the temperature information of the cold storage mechanism.

[0054] Obtain the temperature information of the cold storage mechanism through a temperature sensor, and this temperature information includes a temperature value.

[0055] Step S22: Determine the temperature change information of the cold storage mechanism within a preset time based on the temperature information.

[0056] The controller determines the temperature change information of the cold storage mechanism within a preset time based on the temperature information. The preset time can be 80 minutes, 60 minutes, 40 minutes, etc., without specific limitation.

[0057] Step S23: Determine the first working state of the cold storage mechanism based on the temperature change information.

[0058] The controller determines the first working state of the cold storage mechanism based on the temperature change value of the cold storage mechanism. The first working state of the cold storage mechanism includes a cold storage state and a non-cold storage state.

[0059] Specifically, obtain the temperature drop value of the cold storage mechanism within the preset duration based on the temperature change information; in response to the temperature drop value being greater than the first preset value, determine that the first working state of the cold storage mechanism is the cold storage state.

[0060] Wherein, the second preset value can be set according to the minimum amount of cold absorbed by the cold storage mechanism during the preset cold storage duration.

[0061] Since the temperature of the cold storage mechanism will drop when the cold storage mechanism stores cold, therefore, when the temperature drop value of the cold storage mechanism is greater than the first preset value, the controller can determine that the first working state of the cold storage mechanism is the cold storage state.

[0062] Step S24: In response to the first working state being the cold storage state, control the air supply mechanism to operate in the first air supply mode so that the cold storage mechanism can store cold quickly.

[0063] The controller determines that the first working state of the cold storage mechanism is the cold storage state, and then controls the air supply mechanism to act in the first air supply mode so that the cold storage mechanism can store cold quickly.

[0064] Wherein, the first air supply mode of the air supply mechanism can increase the cold quantity directed to the cold storage mechanism compared with other air supply modes of the air supply mechanism, so that the cold storage mechanism enters the fast cold storage mode and stores cold quickly.

[0065] Optionally, in response to the temperature rise value being less than or equal to the first preset value, determine the second working state of the cold storage mechanism based on the temperature information.

[0066] The controller determines that the temperature rise value of the cold storage mechanism is less than or equal to the first preset value, and can determine that the ice-making mechanism is in the non-ice-making state, and then further determine the first working state of the cold storage mechanism based on the temperature information of the cold storage mechanism. Wherein, the first working state of the cold storage mechanism includes a cold storage state and a non-cold storage state.

[0067] This embodiment can provide cold air to the cold storage mechanism and the ice-making mechanism through the air supply mechanism, and can store cold through the cold storage mechanism to provide cold energy to the ice-making mechanism through the cold storage mechanism, enabling the ice-making mechanism to quickly make ice; and based on the temperature change value of the cold storage mechanism within a preset time, it can automatically determine whether the cold storage mechanism is in the cold storage state. If it is in the cold storage state, the fan is controlled to operate in the first air supply mode, enabling the cold storage mechanism to quickly store cold. Thus, not only can the cold storage mechanism timely replenish cold energy, but also the cold storage time of the cold storage mechanism can be shortened, the cold storage utilization rate of the cold storage mechanism can be improved, the energy consumption required for ice-making can be reduced, and the ice-making efficiency can be improved.

[0068] The present application further proposes a control method for a refrigeration device according to another embodiment. As Figure 3 shown, the control method of this embodiment specifically includes the following steps:

[0069] Step S301: Obtain the temperature information of the cold storage mechanism.

[0070] For specific implementation manners, reference can be made to the above embodiments.

[0071] Step S302: Determine the temperature change information of the cold storage mechanism within a preset time based on the temperature information.

[0072] For specific implementation manners, reference can be made to the above embodiments.

[0073] Step S303: Determine the temperature rise value of the cold storage mechanism within a preset time based on the temperature change information.

[0074] Step S304: In response to the temperature rise value being greater than a second preset value, determine that the second working state of the ice-making mechanism is the ice-making state.

[0075] The controller determines the second working state of the ice-making mechanism based on the temperature rise value of the cold storage mechanism within a preset time. The second working state of the ice-making mechanism includes the ice-making state and the non-ice-making state.

[0076] The second preset value can be set according to the minimum cold energy absorbed by the ice-making mechanism from the cold storage mechanism during the preset ice-making duration.

[0077] When the user puts the ice-making liquid into the ice-making mechanism in the freezer compartment to make ice, the ice-making liquid absorbs cold energy from the cold storage mechanism, causing the temperature of the cold storage mechanism to rise. Therefore, when the temperature rise value of the cold storage mechanism is greater than the second preset value, the controller can determine that the second working state of the ice-making mechanism is the ice-making state.

[0078] Step S305: In response to the second working state being the ice-making state, control the air supply mechanism to operate in the second air supply mode to enable the ice-making mechanism to quickly make ice.

[0079] When the controller determines that the second working state of the ice making mechanism is the ice making state, it controls the air supply mechanism to operate in the second air supply mode so that the ice making mechanism can make ice quickly.

[0080] Among them, compared with other air supply modes of the air supply mechanism, the second air supply mode of the air supply mechanism can increase the cold quantity directed to the ice making mechanism, so that the ice making mechanism enters the fast ice making mode and makes ice quickly.

[0081] When the user puts the ice making liquid into the ice making mechanism in the freezer to make ice, the temperature information of the cold storage mechanism will change (the cold storage mechanism is usually always in the freezer without replacement). Therefore, in this embodiment, based on the temperature rise value of the cold storage mechanism, the ice making state of the ice making mechanism can be accurately identified; further, when the ice making mechanism is in the ice making state, the air supply mechanism is controlled to work in the second air supply mode that can make the ice making mechanism make ice quickly, so that the ice making mechanism can make ice quickly, that is, the ice making mechanism enters the fast ice making mode. Therefore, this embodiment can automatically identify the ice making state of the ice making mechanism, and the ice making mechanism can automatically enter the fast ice making mode, which can greatly improve the intelligent level of the control of the refrigeration equipment and improve the user experience.

[0082] Step S306: In response to the temperature rise value being less than or equal to the second preset value, obtain the temperature drop value of the cold storage mechanism within a preset time period based on the temperature change information.

[0083] Step S307: In response to the temperature drop value being greater than the first preset value, determine that the first working state of the cold storage mechanism is the cold storage state.

[0084] Step S308: In response to the first working state being the cold storage state, control the air supply mechanism to work in the first air supply mode so that the cold storage mechanism can store cold quickly.

[0085] For the specific implementation manners of steps S306 to S308, reference can be made to the above embodiments.

[0086] It can also use Figure 3 The embodiment method to improve the above other embodiments.

[0087] In other embodiments, it is also possible to make a determination on the temperature drop value of the cold storage mechanism and then make a determination on the temperature rise value of the cold storage mechanism.

[0088] Optionally, the ice making mechanism and the cold storage mechanism are arranged at the air outlet, and the ice making mechanism is located above the cold storage mechanism. The included angle between the air damper and the axis of the air outlet in the second air supply mode is smaller than the included angle between the air damper and the axis of the air outlet in the first air supply mode, so that when the ice making mechanism is in the ice making state, the baffle directs more cold air to the ice making mechanism, and when the cold storage mechanism is in the cold storage state, the baffle directs more cold air to the cold storage mechanism.

[0089] The present application further provides a control method for a refrigeration device, which can be used in the above-mentioned refrigeration device, such as Figure 5 shown Figure 5 FIG. is a schematic flowchart of an embodiment of the control method for the refrigeration device of the present application. The control method of this embodiment can be used in the above-mentioned refrigeration device, and specifically may include the following steps:

[0090] Step S31: Obtain the door opening / closing information of the freezer compartment.

[0091] Obtain the door opening / closing information of the freezer compartment through a detection component, and the door opening / closing information includes an opening action.

[0092] Step S32: In response to the opening action of the freezer compartment, obtain the temperature information of the cold storage mechanism.

[0093] Step S33: Determine the temperature change information of the cold storage mechanism within a preset time based on the temperature information.

[0094] Step S34: Determine the temperature rise value of the cold storage mechanism within a preset time based on the temperature change information.

[0095] Step S35: In response to the temperature rise value being greater than a second preset value, determine the second working state of the ice-making mechanism as the ice-making state.

[0096] Step S36: In response to the second working state being the ice-making state, control the air supply mechanism to operate in the second air supply mode to enable the ice-making mechanism to make ice quickly.

[0097] Step S37: In response to the temperature rise value being less than or equal to the second preset value, obtain the temperature drop value of the cold storage mechanism within a preset duration based on the temperature change information.

[0098] Step S38: In response to the temperature drop value being greater than a first preset value, determine the first working state of the cold storage mechanism as the cold storage state.

[0099] Step S39: In response to the first working state being the cold storage state, control the air supply mechanism to operate in the first air supply mode to enable the cold storage mechanism to store cold quickly.

[0100] For the specific implementation manners of steps S33 to S39, reference can be made to the above-mentioned embodiments.

[0101] When the user operates the door of the freezer when ice making is required, the door will be opened. After the controller obtains the door opening action of the freezer, it can determine that the user may have an ice making demand and an ice making action. Therefore, the controller further obtains the temperature rise value of the cold storage mechanism based on the temperature change information of the cold storage mechanism within a preset time period to determine whether the ice making mechanism is in the ice making mode. When the user puts the ice making liquid into the ice making mechanism in the freezer for ice making, the ice making liquid will absorb cold from the cold storage mechanism, causing the temperature of the cold storage mechanism to rise. Therefore, when the temperature rise value of the cold storage mechanism is greater than the second preset value, the controller can determine that the second working state of the ice making mechanism is the ice making state.

[0102] This embodiment further determines the cold storage state of the cold storage mechanism and can accelerate the cold storage of the cold storage mechanism by adjusting the air supply mode of the air supply mechanism. After determining the door opening action in this embodiment, first, the temperature rise value of the cold storage mechanism is used to determine whether the ice making mechanism is in the ice making state. Since the ice making mechanism will absorb cold from the cold storage mechanism when it is in the ice making state, and after the ice making mechanism finishes ice making, that is, when it is in the non-ice making state, the temperature drop of the cold storage mechanism is further used to determine whether the cold storage mechanism is in the cold storage state. Because the temperature of the cold storage mechanism will decrease when it is in the cold storage state, and when the cold storage mechanism is in the cold storage state, the air supply mechanism is adjusted to act in the first air supply mode to accelerate the cold storage of the cold storage mechanism, so as to provide cold for the ice making of the ice making mechanism. Therefore, this embodiment can realize the automatic switching between the fast ice making mode and the fast cold storage mode of the refrigeration equipment; and in this embodiment, the ice making state is determined first, and then the cold storage state is determined, which can accelerate the ice making speed of the ice making mechanism and quickly cold store the cold storage mechanism after ice making is completed.

[0103] Of course, in other embodiments, after determining the door opening action, the cold storage state can be determined first, and then the ice making state can be determined. The cold storage mechanism can be made to quickly store cold first, and then the ice making mechanism can be made to quickly make ice.

[0104] In other embodiments, the determination of the cold storage state of the cold storage mechanism and the corresponding adjustment of the air supply mode of the air supply mechanism can also be performed when the door opening and closing information is not monitored.

[0105] Optionally, the temperature drop value of the cold storage mechanism within a preset time period is obtained based on the temperature information; in response to the temperature drop value being greater than the first preset value, it is determined that the first working state of the cold storage mechanism is the cold storage state.

[0106] Since the ice making mechanism will not absorb cold from the cold storage mechanism when it is in the non-ice making state, and the temperature of the cold storage mechanism will decrease when it is in the cold storage state, the controller can determine that the first working state of the cold storage mechanism is the cold storage state when the temperature drop value of the cold storage mechanism is greater than the first preset value.

[0107] In response to the temperature drop value of the cold storage mechanism being less than or equal to the first preset value, it is determined that the working state of the cold storage mechanism is a non-cold storage state.

[0108] After the controller obtains the door opening action, it can be determined that the refrigeration device may perform ice making or cold storage. If the temperature rise value of the cold storage mechanism is less than or equal to the second preset value and the temperature drop value is less than or equal to the first preset value, it is determined that the refrigeration device does not need to perform ice making or cold storage.

[0109] In another embodiment, in response to the first working state being a non-cold storage state or the door opening action of the freezer not being obtained, the air supply mechanism is controlled to operate in the third air supply mode.

[0110] If the controller determines that the second working state of the ice making mechanism is a non-ice making state and the first working state of the cold storage module is a non-cold storage state, or the controller does not obtain the door opening action of the freezer, the air supply mechanism is controlled to operate in the third air supply mode.

[0111] Wherein, the rotation speed of the compressor in the first air supply mode and the second air supply mode is greater than the rotation speed of the compressor in the third air supply mode; and / or, the rotation speed of the fan in the first air supply mode and the second air supply mode is greater than the rotation speed of the fan in the third air supply mode.

[0112] The third air supply mode is the default air supply mode when the refrigeration device is working normally. The controller controls the rotation speed of the compressor and / or the fan in the first air supply mode and the second air supply mode to be greater than the rotation speed in the third air supply mode, which can make the cooling capacity in the first air supply mode and the second air supply mode greater than the cooling capacity in the third air supply mode.

[0113] The controller not obtaining the door opening action of the freezer means that the controller does not obtain the door opening action within a preset time period, and the preset time period is greater than the sum of the preset time periods for obtaining the temperature rise value and the temperature drop value and the ice making time period and the cold storage time period.

[0114] Similar improvements can be made to the above other embodiments.

[0115] In another embodiment, in response to the first working state being an ice making state, the air supply mechanism is controlled to continuously operate in the first air supply mode for a preset time period, so that the air supply mechanism is not affected by other factors when in the ice making state and adjusts its working state, so that the ice making mechanism is always in a fast ice making state when making ice, thereby improving the ice making efficiency.

[0116] In another embodiment, as Figure 6As shown, after the refrigeration device is powered on, the controller obtains the door opening / closing information of the freezer compartment to determine whether the door body remains closed. If so, it controls the air supply mechanism to operate in the normal operation mode, that is, the above-mentioned third air supply mode. In the third air supply mode, the air outlet blows upward, so that the cold air is directly introduced into the freezer compartment above the ice-making mechanism, and the rotation speed of the fan and the rotation speed of the compressor (i.e., the compressor) are adjusted to the default gear. If not, that is, the controller determines that the door body has an opening action, it determines whether the temperature rise of the cold storage mechanism within 1 hour is greater than the set value, that is, the above-mentioned first preset value. If the temperature rise is greater than the first preset value, it determines that the ice-making mechanism is in the ice-making state and controls the air supply mechanism to operate in the first air supply mode, so that the ice-making mechanism operates in the fast ice-making mode. In the first air supply mode, the air outlet blows upward, so that the cold air passes through the ice-making surface of the ice-making mechanism, thereby accelerating the ice-making speed of the ice-making mechanism. At the same time, the rotation speed of the fan and the rotation speed of the compressor are adjusted to the strongest gear, and the air supply mechanism is controlled to operate forcibly for a period of time in the first air supply mode. If the temperature rise is less than or equal to the first preset value, it determines whether the temperature drop of the cold storage mechanism within 1 hour is greater than the set value, that is, the above-mentioned second preset value. If the temperature drop is greater than the second preset value, it determines that the cold storage mechanism is in the cold storage state and controls the air supply mechanism to operate in the second air supply mode, so that the cold storage mechanism quickly stores cold. In the second air supply mode, the air outlet blows downward, so that the cold air blows towards the cold storage mechanism, thereby accelerating the cold storage speed of the cold storage mechanism. At the same time, the rotation speed of the fan and the rotation speed of the compressor are adjusted to the strongest gear.

[0117] The first preset value and the second preset value can be the same or different. The rotation speed of the strongest gear of the compressor and the fan is greater than the rotation speed of the default gear. The start and end of the second air supply mode and the third air supply mode can also be controlled according to the compartment request. The compartment request can be generated according to the demand generation or other information of the refrigeration device.
