Description

Technical Field

[0001] The present invention relates to the technical field of ice making, and in particular to a household ice making method for improving the transparency of ice. Background Art

[0002] With the improvement of residents' quality of life and the upgrading of consumption, ice drinks in summer have become a daily necessity for people. Therefore, many ice-making products have emerged, such as ice makers, refrigerators with ice-making functions, etc. At present, automatic ice-making function has become an important selling point of mid-to-high-end household refrigerators.

[0003] Taking the automatic ice making of a refrigerator as an example, the existing automatic ice making process of a refrigerator is mainly the following process.

[0004] Refrigerators are typically connected to a built-in water tank, or they have a filter inside the refrigerator that connects directly to the household water supply. Water from the built-in water tank or the tap water is pumped into ice molds located in the freezer (or a dedicated ice making room).

[0005] After water is poured into the ice mold, the refrigerator's refrigeration system cools the mold. The water freezes starting from the mold's walls and gradually freezes from the outside inward. Alternatively, the ice mold can be attached directly to the evaporator coil to accelerate heat transfer.

[0006] After the ice cubes are frozen and formed, they are demolded. The ice bin is equipped with a device to detect whether it is full of ice. For example, a rotatable plastic or metal rod is installed above the ice bin. When the ice cubes in the ice bin accumulate to a certain height, the rotation of the ice detection rod is blocked. The system recognizes this as a "full ice" signal, and ice making stops.

[0007] Taking household ice making as an example, when a user needs to make ice, he usually adds water to the household ice maker, and then controls the temperature at around -15°C to make ice quickly.

[0008] Both of the above-mentioned methods of making ice at home can quickly make ice cubes, but the transparency of the ice cubes is poor, and it is difficult to achieve the transparency of ice cubes made by commercial ice makers. However, if the components of commercial ice makers are used on household ice-making equipment, there are also reasons such as high cost and limited application space environment. As a result, the transparency of ice made by household ice-making equipment has always been relatively turbid, and the user experience is poor. Summary of the Invention

[0009] In order to solve the technical problem of relatively poor transparency of ice made by household ice-making equipment in the prior art, the present invention provides an ice-making method and a refrigerator.

[0010] The ice making method of the present invention is characterized by comprising:

[0011] Step 1, add water to the ice box;

[0012] Step 2: Determine whether the water temperature is less than or equal to the appropriate ice-making temperature;

[0013] Step 3: If yes, control the refrigeration load to the lowest setting with the highest ice-making temperature as the target temperature, and monitor the light transmittance in the ice-making box; if no, control the refrigeration load to a setting higher than the lowest setting, monitor the water temperature, and return to step 2 to continue the judgment;

[0014] Step 4: When the target temperature is reached and the shutdown point is reached, determine whether the light transmittance in the ice box decreases;

[0015] Step 5: If the temperature has not decreased, determine whether the number of times the shutdown point has been reached at the current target temperature is greater than a preset number, where the preset number is greater than 1; if not, continue to operate at the current target temperature and gear, and return to step 4; if so, decrease the temperature adjustment range based on the current target temperature to form a new target temperature, and continue to operate at the lowest gear of the cooling load after reaching the new target temperature, and return to step 4;

[0016] Step 6: If it decreases, the ice making strategy of the previous round is maintained during the next startup, and ice making is continued until the light transmittance in the ice making box drops to the optimal light transmittance range, and ice making is completed.

[0017] Furthermore, when the water temperature is higher than the suitable ice-making temperature, the refrigeration load is controlled to operate at the highest level.

[0018] Furthermore, the range of the suitable ice-making temperature is [1-r, 1+R], r<1, R>0.

[0019] Furthermore, the maximum ice making temperature is 0°C.

[0020] Furthermore, the temperature adjustment range is the minimum temperature accuracy of the device where the ice box is located.

[0021] Furthermore, before executing step 1, the water quality is tested. If the water quality is unqualified, a prompt is given. If the water quality is qualified, step 1 is executed again.

[0022] Furthermore, in step 1, when the ice box reaches a preset water volume, a sterilization device (such as an ultraviolet sterilization lamp) is used to sterilize for a preset time, and then step 2 is performed.

[0023] The present invention provides an ice-making method for a refrigerator, wherein the refrigerator has an ice-making chamber and an ice-storage chamber, and is characterized in that the ice-making method for the refrigerator comprises:

[0024] When the ice storage chamber is not full, the ice making chamber is controlled to make ice using the ice making method of the above technical solution;

[0025] After ice making is completed, the ice in the ice box is sent to the ice storage room for storage.

[0026] The refrigerator proposed by the present invention adopts the ice making method of the refrigerator of the above technical solution to make ice;

[0027] The refrigerator comprises:

[0028] A chamber, the chamber being divided into an ice making chamber and an ice storage chamber distributed vertically by a movable partition located in a height direction;

[0029] The partition driving member controls the partition to open when ice making is completed, so that the ice making box in the ice making chamber pours the made ice downwards into the ice storage chamber.

[0030] Furthermore, it also includes:

[0031] The rotating mechanism is installed on the top of the chamber and is used to move the ultraviolet sterilization lamp to different positions above the ice making box for sterilization.

[0032] Furthermore, it also includes:

[0033] Water pipe, connecting the water source and ice box;

[0034] Water pump, which pumps water from the water source to the ice box;

[0035] Water quality monitoring sensor, used to detect water quality.

[0036] The present invention divides the ice-making process of household ice-making equipment into multiple scenarios. Ice-making begins at the highest ice-making temperature. If ice can form, ice-making continues slowly at the highest ice-making temperature, thereby improving the transparency of the ice. Unlike existing refrigerators where the ice-making chamber is controlled by the temperature of the freezer compartment, the present invention treats the ice-making chamber as a separate small compartment and controls its cyclic start and stop refrigeration, preventing the freezer compartment's extremely low temperature from causing the ice-making chamber to freeze quickly and affect the transparency of the ice.

[0049] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0050] Thus, a feature indicated in this specification is intended to illustrate one of the features of one embodiment of the present invention, rather than to imply that every embodiment of the present invention must have the described feature. In addition, it should be noted that this specification describes many features. Although certain features can be combined together to illustrate possible system designs, these features can also be used in other, not explicitly described, combinations. Thus, unless otherwise noted, the described combinations are not intended to be limiting.

[0051] In order to improve the ice-making transparency of a household ice-making device and enhance the user experience, the present invention provides an ice-making method that is low in cost and can be adopted by any household ice-making device.

[0052] like Figure 1 As shown, in a basic embodiment, the ice making method of the present invention includes the following steps.

[0053] Step 1, add water to the ice box;

[0054] Step 2: Determine whether the water temperature is less than or equal to the appropriate ice-making temperature;

[0055] Step 3: If yes, control the refrigeration load to the lowest setting with the highest ice-making temperature as the target temperature, and monitor the light transmittance in the ice-making box; if no, control the refrigeration load to a setting higher than the lowest setting, monitor the water temperature, and return to step 2 to continue the judgment;

[0056] Step 4: When the target temperature is reached and the shutdown point is reached, determine whether the light transmittance in the ice box decreases;

[0057] Step 5: If the temperature has not decreased, determine whether the number of times the shutdown point has been reached at the current target temperature is greater than a preset number, where the preset number is greater than 1; if not, continue to operate at the current target temperature and gear, and return to step 4; if so, decrease the temperature adjustment range based on the current target temperature to form a new target temperature, and continue to operate at the lowest gear of the cooling load after reaching the new target temperature, and return to step 4;

[0058] Step 6: If it decreases, the ice making strategy of the previous round is maintained during the next startup, and ice making is continued until the light transmittance in the ice making box drops to the optimal light transmittance range, and ice making is completed.

[0059] The present invention first determines the water temperature. If the water temperature is greater than the suitable ice-making temperature, it is quickly cooled. If the water temperature is less than or equal to the suitable ice-making temperature, the target temperature is set to the highest ice-making temperature and ice is made slowly. If the highest ice-making temperature cannot freeze, the temperature is lowered a little and ice is made slowly until the transmittance reaches the optimal transmittance range and ice making is completed. The present invention can find the temperature that can freeze according to the current status of the equipment, and then make ice slowly, so that the ice crystals have enough time to be neatly arranged, thereby improving the transparency of the ice.

[0060] In the above embodiment, if the water temperature is higher than the suitable ice-making temperature, the system may be operated at the highest load level to increase the cooling rate of the water temperature and cool the water temperature to the suitable ice-making temperature as quickly as possible.

[0061] like Figure 2 As shown, in a further embodiment, the range of the suitable ice-making temperature of the present invention is [1-r, 1+R], where r < 1 and R > 0. That is, the suitable ice-making temperature is greater than 0 degrees Celsius, but the specific value can be determined based on the specific equipment. Since 0 degrees Celsius is the standard freezing temperature, when the water temperature is far from 0 degrees Celsius, if the method of the previous embodiment is used to make ice, although ice transparency can be achieved, the ice-making speed is too slow, which can easily affect the user experience.

[0062] like Figure 3 As shown, in a further embodiment, the maximum ice-making temperature is 0°C. Since 0°C is the highest possible freezing temperature, the present invention sets the maximum ice-making temperature at 0°C. If ice can form at 0°C, 0°C is used as the target temperature for ice-making. This prevents ice-making from being too rapid and affecting the transparency of the ice. Due to different regions and different insulation conditions of equipment, those skilled in the art may adjust the specific value of the maximum ice-making temperature as needed.

[0063] like Figure 4 As shown, in one embodiment, the temperature adjustment amplitude is the minimum temperature accuracy of the device housing the ice box. To find the optimal temperature for ice formation, the present invention uses the device's minimum temperature accuracy as the temperature adjustment amplitude. For example, if the minimum temperature accuracy of a refrigerator is 0.5°C, then the temperature adjustment amplitude is set starting from 0°C and decreasing by 0.5°C at a time to find the device's optimal slow freezing temperature. For another example, if the minimum temperature accuracy of a household ice maker is 1°C, then the temperature adjustment amplitude is set starting from 0°C and decreasing by 1°C at a time to find the device's optimal slow freezing temperature.

[0064] like Figure 5 As shown, in a further embodiment, before executing step 1, the water quality is tested, and if the water quality is unqualified, a prompt is given, and if the water quality is qualified, step 1 is executed again. That is, this embodiment includes a pre-step, and the complete process of this embodiment is as follows.

[0065] Pre-step, test the water quality, if the water quality is unqualified, prompt, if the user confirms, then execute step 1, otherwise do not execute step 1, if the water quality is qualified, then execute step 1;

[0066] Step 1, add water to the ice box;

[0067] Step 2: Determine whether the water temperature is less than or equal to the appropriate ice-making temperature;

[0068] Step 3: If yes, control the refrigeration load to the lowest setting with the highest ice-making temperature as the target temperature, and monitor the light transmittance in the ice-making box; if no, control the refrigeration load to the highest setting, monitor the water temperature, and return to step 2 to continue the judgment;

[0069] Step 4: When the target temperature is reached and the shutdown point is reached, determine whether the light transmittance in the ice box decreases;

[0070] Step 5: If the temperature has not decreased, determine whether the number of times the shutdown point has been reached at the current target temperature is greater than a preset number, where the preset number is greater than 1; if not, continue to operate at the current target temperature and gear, and return to step 4; if so, decrease the temperature adjustment range based on the current target temperature to form a new target temperature, and continue to operate at the lowest gear of the cooling load after reaching the new target temperature, and return to step 4;

[0071] Step 6: If it decreases, the ice making strategy of the previous round is maintained during the next startup, and ice making is continued until the light transmittance in the ice making box drops to the optimal light transmittance range, and ice making is completed.

[0072] Water quality is also one of the factors that affect the transparency of ice cubes. Therefore, water quality is tested before ice making. If the water quality does not meet the requirements, the user can be notified to know the reason for the low transparency of the ice. If the water quality does meet the requirements, the slow ice making method of the present invention can be used to produce ice cubes with the required transparency.

[0073] like Figure 6 As shown, in a further embodiment, in step 1, when the ice box reaches a preset water volume, a sterilization device is used to sterilize the ice box for a preset time period before executing step 2. Because filters can only filter out impurities and cannot remove pathogens in the water, adding a corresponding sterilization device is more beneficial to health. For example, an ultraviolet sterilization lamp can be used for sterilization. This sterilization device is relatively easy to install in household ice-making equipment such as refrigerators and is simple to implement.

[0074] When the above-mentioned ice-making method of the present invention is applied in a refrigerator, the present invention protects the ice-making method of the refrigerator. The refrigerator to which the ice-making method of the present invention can be applied has an ice-making chamber and an ice storage chamber. The ice-making method of the refrigerator includes the following steps.

[0075] When the ice storage compartment is not full, the ice making compartment is controlled to make ice using the ice-making method described above. After ice making is complete, the ice in the ice box is transferred to the ice storage compartment for storage. The ice-making method of the present invention enables sufficiently transparent ice cubes to be produced even in a refrigerator. When the ice-making method of the present invention is used in a refrigerator, the highest and lowest load levels are controlled by controlling the state and size of the damper in the ice making compartment. For example, when the refrigerator reaches a shutdown point, the damper is closed to prolong the current temperature and give the ice making compartment sufficient time to make ice.

[0076] A refrigerator may have multiple ice-making modes, such as a standard mode and a fast ice-making mode. If the user selects the fast ice-making mode, ice is made using an existing conventional ice-making method, which only considers ice-making efficiency and not ice transparency. If the user selects the standard mode, which indicates that the user does not care about ice-making efficiency, the ice-making method of the present invention may be used to improve ice transparency. Of course, refrigerators may also have other ice-making modes, and the specific names of the ice-making modes may be modified by those skilled in the art as needed.

[0077] The present invention also protects a refrigerator, which makes ice by adopting the above-mentioned ice-making method for a refrigerator.

[0078] In terms of specific structure, the refrigerator includes a chamber, a movable partition and a partition driving member.

[0079] like Figure 8As shown, the chamber is divided into an ice-making chamber 2 and an ice-storage chamber 3 distributed above and below by a movable partition located in the height direction. The ice-making chamber is located above the ice-storage chamber, and the movable partition is movable, for example, it can be pulled out like a drawer panel so that the chamber becomes an integral chamber after the movable partition is pulled out. When the movable partition is inserted into the chamber, the chamber is divided into an ice-making chamber and an ice-storage chamber.

[0080] When ice making is completed, the partition driving component controls the movable partition to open, so that the ice making box in the ice making chamber pours the made ice downwards into the ice storage chamber.

[0081] The present invention divides the ice making chamber and the ice storage chamber into different spaces, which is conducive to the temperature control of each. The ice storage chamber is used to store ice to prevent ice cubes from sticking to each other. The ice making chamber needs to make ice slowly, so the required temperatures of the two are different.

[0082] like Figure 7 As shown, in a further embodiment, the refrigerator of the present invention further includes a rotating mechanism 1 .

[0083] A rotating mechanism 1 is mounted at the top of the chamber and is used to move a sterilization device (such as an ultraviolet germicidal lamp) to different positions above the ice box for sterilization. If the sterilization device is a UV germicidal lamp, one edge of the UV germicidal lamp's illumination range can be positioned so that the center of the rotating mechanism projects toward (near) the center of the ice box, while the other edge covers the edge of the ice box at an angle α. This ensures that the rotating mechanism covers the ice box as much as possible as it rotates.

[0084] In this embodiment, the sterilization device is made movable, which is conducive to comprehensive sterilization and avoids blind spots or dead corners in fixed sterilization devices.

[0085] In one embodiment, the refrigerator of the present invention further includes a water pipe, a water pump, and a water quality detection sensor.

[0086] The water pipe connects the water source and the ice box;

[0087] The water pump draws water from the water source to the ice box;

[0088] Water quality detection sensors are used to detect water quality.

[0089] In this embodiment, the water pipe is directly connected to the municipal tap water, and then filtered through the filter. If the water quality detection sensor detects that the water quality is unqualified, it will not be sent to the ice making box. If the water quality is qualified, it can be sent to the ice making box.

[0090] The concept of the present invention is described below using a refrigerator as a specific embodiment.

[0091] like Figure 9As shown, the ice storage chamber of the refrigerator of this embodiment is provided with a gravity sensor, which can detect the weight of ice cubes and judge whether it is full of ice or not by the weight of ice cubes.

[0092] Step 1: Power on, the ice making mechanism performs a reset operation, and then proceed to step 2;

[0093] Step 2: The gravity sensor in the ice storage chamber detects the mass m1 of the ice cubes. Each ice cube weighs m, and the number of ice cubes n = m1 / m. Then, proceed to step 3.

[0094] Step 3: Determine whether n is greater than N, where N=500. If so, determine that the ice is full; if not, determine that the ice is not full; then proceed to step 4;

[0095] Step 4: Display the ice making status and ice making amount, then proceed to step 5;

[0096] Step 5: Determine whether the ice-making function is set. If so, proceed to step 6. If not, turn off the ice-making function, perform corresponding processing on the load, and return to step 2 to wait for the user to turn on the ice-making function. If the user originally turned on the ice-making function and completed water filling, and the user turned off the ice-making function during ice making, the refrigerator controller will make a mark. The next time the user sets the ice-making function, the refrigerator controller will no longer control water filling and directly proceed to step 7.

[0097] Step 6: Turn on the water pump and fill the water for t1 time. Here, t1 is determined by the size of the ice box and the flow rate. For example, it can be set to 9 seconds. During the water filling process, the water quality detection sensor detects whether the water quality meets the drinking standard. If yes, go to step 7. If not, remind the user to replace the filter. After the user confirms that the filter has been replaced, go to step 7.

[0098] Step 7: After the water filling is completed, the rotating mechanism is turned on to drive the ultraviolet sterilization lamp to perform forced sterilization. The sterilization time t2 is 15 minutes. After the sterilization is completed, the transmittances A1 and A2 received by the photoelectric receivers on both sides of the ice making box are recorded, and then step 8 is executed;

[0099] Step 8: The infrared temperature sensor detects whether the water temperature T in the ice box is above T1, where T1 is 1 degree. If so, the ice chamber is set to the coldest setting TS1, where TS1 = -26 degrees. The compressor and fan are set to high settings to quickly cool the chamber. The water temperature T is continuously detected in step 8. If the water temperature T becomes T1 or below, step 9 is executed. If the water temperature T is less than or equal to T1 at the beginning, step 9 is directly executed.

[0100] Step 9: Lower the target temperature of the ice making chamber by 1 degree, i.e., make ice with 0 degree as the target temperature, and detect the light transmittances B1 and B2 on both sides of the ice making box in real time, then proceed to step 10;

[0101] Step 10: If the ice making chamber temperature reaches the current target temperature (initial 0 degrees), the load is operated at the lowest gear, for example, the damper is opened to the minimum, or the compressor and fan are operated at the lowest speed, or the damper is fully closed, then step 12 is executed; if not, step 11 is executed;

[0102] Step 11: Determine whether the temperature of the ice making chamber reaches or is lower than the shutdown point. If so, the compressor and fan are shut down, or the damper is closed, the shutdown count is increased by one, and then step 13 is executed. If not, return to step 10.

[0103] Step 12: Determine whether one of A1-B1 and A2-B2 is greater than 0. If yes, proceed to step 14. If not, proceed to step 13.

[0104] Step 13: Determine whether the machine has reached the three stop points. If yes, return to step 9; if not, return to step 10.

[0105] Step 14: Continue to start and stop the operation according to the current set temperature, and then go to step 15;

[0106] Step 15: Determine whether the difference between A1-B1 and A2-B2 is greater than or equal to C, where C=20%. If so, prepare to separate the ice and proceed to step 16. If not, return to step 14.

[0107] Step 16: Determine whether the water quality in step 6 meets the standard. If so, proceed to step 17. If not, wait for the user to press the forced ice release button to release the ice.

[0108] Step 17: Execute automatic ice separation. Open the partitions between the ice making and storage compartments. After ice separation is complete, close the partitions and activate the UV sterilizer for forced sterilization. Sterilization lasts for t5 (here, t5 = 10 minutes). A gravity sensor in the ice storage compartment monitors ice quality and controls the ice storage compartment to -3 degrees Celsius. When the humidity reaches E (here, E = 30%), activate the dehumidifier. Otherwise, dehumidify the ice storage compartment to ensure condensation-free ice storage and prevent ice from frosting or clinging. Forced sterilization occurs each time ice is removed. Continue with step 2.

[0109] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
