[0033] The refrigeration equipment refers to a device combining a refrigeration machine with a facility using cold energy together for reducing or maintaining the temperature of a specific space or substance. With the continuous progress of science and technology and the improvement of people's requirements for the quality of life, the refrigeration equipment has experienced a development process from simple to complex, from low-end to high-end, and from single function to multi-function. At present, the refrigeration equipment based on mechanical temperature control has a high market share. Such refrigeration equipment usually has multiple mechanical temperature adjustment temperature adjustment gears, and the user adjusts the temperature of the refrigeration equipment by manually adjusting different gears. Since the user cannot accurately determine the gear that the refrigeration equipment should be set to, the gear setting may be unreasonable, thereby causing poor refrigeration effect or overloading of the refrigeration equipment.

[0034] The embodiments of the present application adjust the gear of the gear knob through the gear adjusting device arranged on the gear knob. The controller obtains the target gear according to the current internal temperature and the current external temperature of the refrigeration equipment. Thus, the gear adjusting device adjusts the gear knob to the target gear.

[0035] Reference Figure 1 A structural schematic view of the refrigeration equipment is provided in the present application.

[0036] The refrigeration equipment 100 provided by the present application comprises a gear knob 200, a gear adjusting device 300 arranged on the gear knob 200, and a controller.

[0037] Figure 1 The position shown by the middle gray area is the position where the gear adjusting device 300 is installed. The gear knob 200 is arranged on the inner wall of the refrigeration equipment 100, and the gear adjusting device 300 is installed on the gear knob 200.

[0038] Figure 1The controller is not shown, and in an actual application scenario, the controller can be located inside the refrigeration equipment 100. The specific setting position of the controller is not limited by the present application.

[0039] The refrigeration equipment 100 can be a refrigerator, a freezer, a cold storage, a refrigerated container, etc., and the present application does not make any limitation thereon.

[0040] The gear adjusting device 300 is used for adjusting the gear of the gear knob 200.

[0041] The controller is used for obtaining a current internal temperature inside the refrigeration equipment 100 and a current external temperature outside the refrigeration equipment 100, judging whether a temperature adjustment condition is met according to the current internal temperature and the current external temperature, obtaining a target gear temperature according to the current external temperature if the temperature adjustment condition is met, obtaining a mapping relationship between the target gear temperature and a target gear, obtaining the target gear corresponding to the target gear temperature according to the mapping relationship between the target gear temperature and the target gear, and controlling the gear adjusting device 300 to adjust the gear knob 200 to the target gear.

[0042] The refrigeration equipment provided by the embodiment of the present application adjusts the gear of the gear knob through the gear adjusting device arranged on the gear knob. The controller obtains a target gear temperature according to a current internal temperature and a current external temperature of the refrigeration equipment, and then obtains a target gear corresponding to the target gear temperature according to a mapping relationship between the target gear temperature and the target gear. Thus, the gear adjusting device installed on the gear knob of the refrigeration equipment is controlled to adjust the gear knob to the target gear. The refrigeration equipment can automatically adjust the gear knob to the appropriate target gear according to the temperature change, so that the internal temperature of the refrigeration equipment can be maintained within an appropriate range, the refrigeration effect is ensured, the probability of overloading of the refrigeration equipment is reduced, and the energy consumption is reduced.

[0043] Figure 2 FIG. 1 is a structural schematic diagram of a gear adjusting device provided by the embodiment of the present application.

[0044] As shown in FIG. 1, the gear adjusting device 300 includes a housing 310, a fixing assembly 320 arranged on the housing 310, and a gear rotating assembly 330 arranged on the housing 310. Figure 2

[0045] The housing 310 can be a cuboid, a cube or other polygonal solid, and the present application does not make any limitation thereon.

[0046] The fixing assembly 320 is used for fixing the housing 330 on the gear knob 200.

[0047] The housing 310 is provided with a groove, as shown in FIG. 1.​Figure 2 The gear rotating assembly 330 is located in the groove as shown by the gray part; the gear rotating assembly 330 is used to rotate the gear knob 200.

[0048] One end of the fixing assembly 320 is fixedly connected with the connecting shell 310, and the other end contacts and is adsorbed on the inner wall of the refrigeration equipment; meanwhile, the gear knob 200 provided on the inner wall of the refrigeration equipment 100 is located in the groove, so that the fixing assembly 320 fixes the shell 310 on the gear knob 200.

[0049] In addition, the gear rotating assembly 330 is located in the groove and surrounds the gear knob 200, so that the gear knob 200 can be rotated by the gear rotating assembly 330 to adjust the gear.

[0050] In some embodiments, as shown in Figure 2 The fixing assembly 320 comprises a plurality of electromagnetic columns 321 which are uniformly distributed on one side of the shell 310 provided with the groove.

[0051] The electromagnetic columns 321 have the same height and are uniformly distributed on one side of the shell 310 provided with the groove, so that the shell 310 can be fixed while the gear knob 200 is located in the groove of the shell 310.

[0052] In the embodiment of the utility model, the number of electromagnetic columns 321 is four, which can ensure the stable connection of the shell 310 and the gear knob 200 while saving the cost. In other embodiments, the number of electromagnetic columns 321 can be set according to the actual situation, and the utility model does not limit this.

[0053] The bottom surface shape of the electromagnetic column 321 can be any shape such as a circle, a square or an ellipse, and the utility model does not limit this.

[0054] In some embodiments, the fixing assembly 320 further comprises an electromagnetic switch which is used to turn on the electromagnet to make the electromagnetic column 321 generate the adsorption force.

[0055] After the electromagnetic switch is turned on, the electromagnetic column 321 can generate the adsorption force, so as to be adsorbed on the inner wall of the refrigeration equipment 100, and the gear adjusting device 300 is fixed on the gear knob 200 of the refrigeration equipment 100 through the fixing assembly 320.

[0056] Figure 3 It is a structure schematic view of a gear rotating assembly provided by the embodiment of the utility model.

[0057] As shown in Figure 3 The gear rotating assembly 330 comprises a tension component 331 and an anti-skid component 332.

[0058] After receiving the rotation command and rotation data sent by the controller, the gear adjustment device 300 controls the gear rotation component 330 to rotate the gear knob 200 to adjust the gear according to the received rotation command and rotation data.

[0059] The tensioning component 331 is an annular structure located on the side wall of the groove. The tensioning component 331 surrounds the gear knob 200 and is used to tighten and fit the gear knob 200 inward and rotate the gear knob 200.

[0060] It is worth noting that the tensioning component 331 refers to a mechanical component that can be tightened to fit the gear knob 200 and can be opened to release the gear knob 200.

[0061] like Figure 3 As shown, the tensioning component 331 includes multiple metal pillars. These metal pillars can adhere to and fix the gear knob 200 when the tensioning component 331 is tightened inward. Rotating the tensioning component 331 causes the gear knob 200, which is fixed to the tensioning component 331, to rotate accordingly. Conversely, when the tensioning component 331 is opened inward or outward, these metal pillars release the gear knob 200, thus not affecting the gear knob 200.

[0062] The anti-slip component 332 is an annular structure located inside the tensioning component 331, used to increase the friction between the tensioning component 331 and the gear knob 200 when the tensioning component 331 rotates the gear knob 200.

[0063] In some embodiments, the anti-slip component 332 is an anti-slip rubber ring. In other embodiments, the anti-slip component 332 may be made of other anti-slip materials, and this invention does not limit this.

[0064] The anti-slip component 332 is located between the tensioning component 331 and the gear knob 200, and can increase the friction when the tensioning component 331 rotates the gear knob 200.

[0065] In some embodiments, the controller is configured to acquire the current internal temperature inside the refrigeration device and the current external temperature outside the refrigeration device;

[0066] The current internal temperature inside the refrigeration equipment refers to the real-time internal temperature detected in the refrigeration chamber of the refrigeration equipment; the current external temperature outside the refrigeration equipment refers to the real-time ambient temperature near the refrigeration equipment, which is detected in the space where the refrigeration equipment is placed.

[0067] In some embodiments, the controller is configured to acquire the current internal temperature detected by an internal temperature sensor arranged in the refrigeration device; and acquire the current external temperature detected by an indoor temperature sensor arranged outside the refrigeration device.

[0068] The internal temperature sensor is arranged in a refrigeration space of the refrigeration device, and is configured to detect a temperature in a refrigeration compartment of the refrigeration device in real time.

[0069] The internal temperature sensor can capture subtle temperature changes in the refrigeration device in real time, and convert the accurate temperature data into an electrical signal or other identifiable format and then transmit the same to the controller. After receiving the temperature data, the controller analyzes the temperature in the refrigeration device detected in real time, and then adjusts the refrigeration device to keep the temperature in the refrigeration device within a desired range.

[0070] The internal temperature sensor has the characteristics of high precision, high stability and high sensitivity, and can accurately reflect the temperature in various complex environments. Such a high-precision temperature sensor can play an important monitoring role for items that need to be strictly controlled in temperature conditions, such as food, medicine, biological products, etc.

[0071] In actual application scenarios, the controller is in communication connection with an application program installed in the terminal device. Thus, the temperature data detected by the internal temperature sensor can be transmitted to the application program, so that a user can check the temperature data in the application program of the terminal device.

[0072] The terminal device can be an electronic device such as a smartphone, a tablet, a notebook computer, etc., and the terminal device has an application program of the integrated control system installed therein. The specific type of the terminal device is not limited in the present application.

[0073] The indoor temperature sensor is arranged near the refrigeration device, and is configured to detect an ambient temperature of the refrigeration device in real time, i.e., an external temperature of the refrigeration device.

[0074] The indoor temperature sensor is arranged in the surrounding environment of the refrigeration device, and its main responsibility is to monitor and accurately feedback the temperature of the environment in which the refrigeration device is located in real time. In actual application, the indoor temperature sensor can capture subtle temperature changes in the surrounding environment of the refrigeration device in real time, and convert the temperature data into an electrical signal or other identifiable format, and then transmit the same to the controller. After receiving the temperature data, the controller analyzes the ambient temperature of the refrigeration device detected in real time, and then adjusts the operating state of the refrigeration device, such as the working strength of the compressor, to avoid overloading of the refrigeration device.

[0075] In actual application scenarios, the indoor temperature sensor can be arranged at a position 10 cm away from the refrigeration device in a room in which the refrigeration device is placed.

[0076] In some embodiments, the controller is configured to determine whether a temperature adjustment condition is satisfied based on the current internal temperature and the current external temperature.

[0077] The current internal temperature and the current external temperature are used to determine whether the temperature in the refrigeration device is appropriate, and thus whether the set gear of the refrigeration device is reasonable. If the current internal temperature and the current external temperature do not satisfy the temperature adjustment condition, the gear does not need to be adjusted. If the current internal temperature and the current external temperature satisfy the temperature adjustment condition, the gear needs to be adjusted.

[0078] To accurately determine whether the temperature in the refrigeration device is appropriate, and thus to evaluate whether the set gear is reasonable, the difference between the current internal temperature and the current external temperature, the corresponding relationship, and the working efficiency of the refrigeration device need to be considered comprehensively.

[0079] The real-time temperature data in the refrigeration device is obtained by the in-warehouse temperature sensor, and compared with the preset optimal temperature range. Meanwhile, the ambient temperature is monitored by the external temperature sensor, which helps to measure the external conditions of the refrigeration device. The difference between the internal temperature and the external temperature can reflect the working load and efficiency of the refrigeration device. If the internal temperature is much higher than the optimal temperature range, and the external temperature is moderate or low, it may mean that the set gear of the refrigeration device is too low, and the refrigeration device cannot effectively cool down. Therefore, appropriately increasing the gear can speed up the cooling speed, so that the internal temperature reaches the optimal temperature as soon as possible. On the contrary, if the external temperature is high, and the internal temperature is at or below the optimal temperature range, the refrigeration device is still running at high intensity, which may mean that the set gear is too high, and it is easy to cause unnecessary energy consumption and possible equipment wear and tear. In this case, reducing the gear can not only maintain the suitability of the internal temperature, but also save energy and prolong the service life of the equipment.

[0080] In addition, the type and capacity of the refrigeration device, and the size and thermal insulation performance of the room can also be considered, which will also affect the accuracy of temperature adjustment and the rationality of gear setting. By comprehensively analyzing these factors, the gear of the refrigeration device can be adjusted more scientifically, to ensure its efficient and energy-saving operation.

[0081] In some embodiments, the controller is configured to obtain a mapping relationship between the current external temperature and a target internal temperature; determine the target internal temperature corresponding to the current external temperature based on the mapping relationship between the current external temperature and the target internal temperature; determine whether the current internal temperature matches the target internal temperature; if the current internal temperature does not match the target internal temperature, determine that the temperature adjustment condition is satisfied; and if the current internal temperature matches the target internal temperature, determine that the temperature adjustment condition is not satisfied.

[0082] The external temperature changes with seasons and other factors, and different external temperatures have corresponding optimal internal temperatures, i.e., the target internal temperature. Setting the internal temperature of the refrigeration device to the optimal temperature can avoid overloading of the refrigeration device, prolong the service life of the refrigeration device, and prevent food or supplies in the refrigeration space from spoiling or freezing.

[0083] It should be noted that "optimal" here means that when the internal temperature set by the refrigeration device is the optimal internal temperature, both good refrigeration effect and energy saving can be achieved.

[0084] After obtaining the mapping relationship between the current external temperature and the target internal temperature, the target internal temperature corresponding to the current external temperature can be determined according to the mapping relationship and the real-time detected current external temperature.

[0085] As an example, when the room temperature is 25-30°C, the optimal internal temperature of the refrigerator cold storage area is 4-7°C; when the room temperature is 5-10°C, the optimal internal temperature of the refrigerator cold storage area is 0-4°C.

[0086] After obtaining the target internal temperature, it is determined whether the detected current internal temperature matches the target internal temperature. That is, it is determined whether the current internal temperature is within the interval range of the target internal temperature. If the current internal temperature is not within the interval range of the target internal temperature, it is determined that the temperature adjustment condition is met; if the current internal temperature is within the interval range of the target internal temperature, it is determined that the temperature adjustment condition is not met.

[0087] In some embodiments, the controller is configured to obtain a target gear temperature according to the current external temperature if the temperature adjustment condition is met.

[0088] If the current internal temperature does not match the target internal temperature, i.e., the current internal temperature is not within the interval range of the target internal temperature, the target gear temperature corresponding to the current external temperature is obtained, which is the target internal temperature described above.

[0089] In some embodiments, the current internal temperature is set as T1, the current external temperature is set as T2, and the insulation coefficient of the refrigeration device is set as K. The following formula exists:

[0090] T1=T2*K

[0091] The target gear temperature is set as T N , and the cooling efficiency of the refrigeration device is set as D. The following formula exists:

[0092] T1=T N *D

[0093] According to the above two formulas, the following formula can be obtained:

[0094]

[0095] According to the above formula and the current external temperature, the target gear temperature can be obtained.

[0096] It is worth mentioning that the insulation coefficient of the refrigeration equipment is a fixed value at a certain external temperature, but the insulation coefficient of the refrigeration equipment will change with the change of the external temperature, so the insulation coefficient K of the refrigeration equipment needs to be determined according to the actual situation.

[0097] The cooling efficiency D of the refrigeration equipment is related to the model performance of the refrigeration equipment, and needs to be determined according to the actual situation.

[0098] In some embodiments, the controller is configured to obtain a mapping relationship between the target gear temperature and the target gear; and obtain the target gear corresponding to the target gear temperature according to the mapping relationship between the target gear temperature and the target gear.

[0099] There is a clear corresponding mapping between the target gear temperature and the target gear of the refrigeration equipment. In use, proper adjustment is made according to factors such as season, type of stored goods and energy saving demand, so as to ensure the best operation effect and energy saving performance of the refrigeration equipment. According to the mapping relationship between the target gear temperature and the target gear, the target gear corresponding to the target gear temperature can be obtained.

[0100] As an example, the 0th gear of the refrigerator usually represents the stop gear, and the refrigerator does not cool at this gear, and the internal temperature of the refrigerator approaches the external temperature; the target gear temperature corresponding to the 1st gear is 7℃-10℃; the target gear temperature corresponding to the 2nd gear is 4℃-7℃; the target gear temperature corresponding to the 3rd gear is 0℃-4℃.

[0101] In some embodiments, the controller is configured to control the gear adjusting device to adjust the gear knob to the target gear.

[0102] The controller generates a rotation command and rotation data according to the target gear, and sends the rotation command and rotation data to the gear adjusting device, so as to control the gear adjusting device to adjust the gear knob to the target gear.

[0103] In some embodiments, the controller is configured to determine the gear angle between every two adjacent gears in the gear knob; judge whether the current gear is consistent with the target gear; if the current gear is not consistent with the target gear, determine the rotation angle of the gear adjusting device according to the gear angle, the current gear and the target gear; and control the gear adjusting device to adjust the gear knob to the target gear according to the rotation angle.

[0104] In actual application scenarios, the user sets the number of gears of the refrigeration equipment and the gear angle between every two adjacent gears in the application program, determines the angle value that the gear adjusting device should rotate, and then sends the angle value to the gear adjusting device to rotate the gear knob.

[0105] It is worth noting that because different models of refrigeration equipment have different numbers of gears, the gear angle between every two adjacent gears is also different. The gear adjusting device can be calibrated before formal use to determine the gear angle between two adjacent gears.

[0106] As an example, first, the number of gears of the refrigeration equipment and the preset gear angle between two adjacent gears of the refrigeration equipment are set in the application program; the gear adjusting device is controlled by the application program to adjust the gear knob and adjust it to the gear specified by the application program; after the gear adjusting device is adjusted, the gear adjusting device is removed, and it is determined whether the gear knob is rotated to the specified position, i.e., whether the gear indicated by the gear knob is the gear specified by the application program; if the gear knob is rotated to the specified position, the calibration is completed, and it is determined that the gear angle between every two adjacent gears in the gear knob is the preset gear angle; if the gear knob is not rotated to the specified position, the gear angle is reset in the application program, and the above operation is repeated until it is determined that the gear angle between every two adjacent gears in the gear knob is the gear angle set in the application program, thereby completing the calibration.

[0107] The angle, thereby completing the calibration.

[0108] Before the gear adjusting device is controlled to rotate the gear knob, it is also necessary to determine whether the current gear and the target gear are consistent. If the current gear and the target gear are consistent, the gear adjusting device does not need to be controlled to rotate the gear knob; if the current gear and the target gear are not consistent, the gear adjusting device needs to be controlled to rotate the gear knob to the target gear.

[0109] As an example, if the current gear is 2 gears and the target gear is 2 gears, the gear adjusting device does not need to be controlled to rotate the gear knob; if the current gear is 0 gears and the target gear is 2 gears, the gear adjusting device needs to be controlled to rotate the gear knob to 1 gear.

[0110] If the preset gear angle is 30°, and the current gear is 0 gears and the target gear is 2 gears, it is determined that the rotation angle of the gear adjusting device is 60°.

[0111] In addition, the rotation direction of the gear adjusting device can be determined according to the size of the current gear and the target gear.

[0112] As an example, if the current gear is 0 gears and the target gear is 2 gears, and the refrigeration equipment needs to be adjusted clockwise to increase the gear, the current gear is smaller than the target gear, and it is determined that the rotation direction of the gear adjusting device is clockwise.

[0113] The rotation data is generated according to the obtained rotation angle and rotation direction of the gear adjusting device, and is sent to the gear adjusting device, so that the gear adjusting device adjusts the gear knob to the target gear according to the rotation angle and rotation direction obtained by the gear adjusting device.

[0114] In some embodiments, the controller is configured to obtain a change rate of the current internal temperature after the gear adjusting device adjusts the gear knob to the target gear, determine whether a gear adjustment success condition is met according to the change rate of the current internal temperature, and return to the step of obtaining the internal temperature in the refrigeration device and the external temperature outside the refrigeration device if the gear adjustment success condition is not met.

[0115] The change rate of the current internal temperature can be obtained according to the temperature in the refrigeration compartment of the refrigeration device detected by the in-compartment temperature sensor in real time. The change rate of the current internal temperature of the refrigeration device can reflect whether the gear setting of the refrigeration device is appropriate.

[0116] In some embodiments, the gear adjustment success condition is met if the change rate of the current internal temperature approaches 0 within a period of time, and the gear adjustment success condition is not met if the change rate of the current internal temperature is greater than 0 and approaches 1 within a period of time.

[0117] If it is determined that the gear adjustment success condition is not met, it means that the target gear needs to be determined again and adjusted, so it is necessary to return to the step of obtaining the internal temperature in the refrigeration device and the external temperature outside the refrigeration device, and re-perform the above steps in order.

[0118] In some embodiments, the controller is configured to generate adjustment record information, the adjustment record information including adjustment time information and adjustment operation information; wherein the adjustment time information is used to record the time when the gear adjusting device adjusts the gear knob to the target gear, and the adjustment operation information is used to record the gear value of the current gear and the gear value of the target gear.

[0119] As an example, if the gear adjusting device performs a rotation adjustment operation on the gear knob at 17:09 Beijing time, 17:09 Beijing time is recorded as the adjustment time, and the adjustment time information is generated; if the gear adjusting device adjusts the gear knob from 1 gear to 2 gear, 1 gear before adjustment and 2 gear after adjustment are recorded, and the adjustment operation information is generated.
