Description

TECHNICAL FIELD

[0001] The present application relates to a refrigeration and freezing technology, and in particular, to a refrigeration and freezing device and a control method thereof. BACKGROUND

[0002] With the development of technology and the increasing demand of users, some refrigerators now have ice-making function. Specifically, some refrigerators with ice-making function usually include a water storage box, a water pump, a water delivery pipeline, an ice maker, a driving device and an ice storage box. The water storage box is used to store water. One end of the water delivery pipeline is in communication with the water storage box, and the other end of the water delivery pipeline is in communication with the ice maker. The water pump is used to pump the water in the water storage box into the water delivery pipeline, and deliver the water in the water delivery pipeline into the ice maker. The ice maker is used to cool the water in it into ice. The ice storage box is located below the ice maker and is used to store ice cubes.

[0003] The above-mentioned ice-making refrigerator with a water storage box needs a water delivery pipeline to connect the water storage box and the ice maker during ice-making process. The part of the water delivery pipeline in the freezer is prone to ice blocking due to low temperature. In addition, the temperature of the water delivery pipeline is relatively low, and the cold energy will be transmitted to the back of the refrigerator through the pipeline, causing condensation on the rubber parts and the back plate near the back of the refrigerator. SUMMARY

[0004] In order to solve the problems raised in the background section, the applicant realizes that the problem can be solved by heating the water delivery pipeline. The problem of ice blocking in the water delivery pipeline and condensation on the back of the refrigerator can be effectively prevented by arranging heating wires on the water delivery pipeline. However, if the heating wires are allowed to work continuously, it will directly waste electricity, and it will also indirectly waste electricity because the additional heat generated will cause the temperature in the freezer to rise, and more cold energy is needed to adjust the temperature in the freezer.

[0005] Therefore, an object of the first aspect of the present application is to provide a control method of a refrigeration and freezing device which can avoid ice blocking in the water delivery pipeline and save electricity.

[0006] Another object of the first aspect of the present application is to increase the hardware structure cost of the refrigeration and freezing device.

[0007] An object of the second aspect of the present application is to provide a refrigeration and freezing device which can avoid ice blocking in the water delivery pipeline and save electricity.

[0008] According to the first aspect of the present application, the present application provides a control method of a refrigeration and freezing device, the refrigeration and freezing device comprising an ice maker arranged in a freezer compartment thereof, a water storage box for providing water for ice-making of the ice maker, a water delivery pipeline connected between the ice maker and the water storage box, and a heating device for selectively heating the water delivery pipeline, the control method comprising:

[0014] Optionally, the freezing mode of the freezer compartment comprises a quick-freezing mode and a regular freezing mode; and

[0015] the ice-making state of the ice maker comprises a normal ice-making state and an abnormal ice-making state.

[0016] Optionally, in the case that the set temperature of the freezer compartment, the freezing mode of the freezer compartment, and the start-stop state of the compressor are the same, a target turn-on probability of the heating device when the ambient humidity is higher than a preset humidity threshold and the ice maker is in the abnormal ice-making state is greater than a target turn-on probability of the heating device when the ambient humidity is lower than the preset humidity threshold and the ice maker is in the abnormal ice-making state.

[0017] Optionally, in the case that the set temperature of the freezer compartment, the freezing mode of the freezer compartment, and the start-stop state of the compressor are the same, a target turn-on probability of the heating device when the ambient humidity is higher than a preset humidity threshold and the ice maker is in the normal ice-making state is equal to a target turn-on probability of the heating device when the ambient humidity is lower than the preset humidity threshold and the ice maker is in the normal ice-making state.

[0018] Optionally, in the case that the ambient humidity and the start-stop state of the compressor are the same, a target turn-on probability of the heating device when the freezer compartment is in the regular freezing mode and the ice maker is in the normal ice-making state is lower than a target turn-on probability of the heating device when the freezer compartment is in the quick-freezing mode and the ice maker is in the normal ice-making state.

[0019] Optionally, when the freezing chamber is in the fast-freezing mode and the ice maker is in the normal ice-making state, the target starting rate of the heating device is a preset highest starting rate.

[0020] Optionally, when the ambient humidity is lower than a preset humidity threshold, the freezing chamber is in the normal refrigeration mode, the set temperature of the freezing chamber is higher than a preset temperature threshold, and the ice maker is in the abnormal ice-making state, the target starting rate of the heating device is zero.

[0021] Optionally, when the ambient humidity is lower than a preset humidity threshold, the freezing chamber is in the normal refrigeration mode and the set temperature of the freezing chamber is lower than a preset temperature threshold, and the ice maker is in the abnormal ice-making state, or when the ambient humidity is lower than a preset humidity threshold, the freezing chamber is in the fast-freezing mode, and the ice maker is in the abnormal ice-making state, the target starting rate of the heating device corresponding to the compressor in the running state is greater than the target starting rate corresponding to the compressor in the stopped state.

[0022] Optionally, when the ambient humidity is higher than a preset humidity threshold, the target starting rate of the heating device corresponding to the compressor in the running state is greater than the target starting rate corresponding to the compressor in the stopped state, except when the freezing chamber is in the fast-freezing mode and the ice maker is in the normal ice-making state.

[0023] According to a second aspect of the present application, the present application further provides a refrigerating-freezing device, comprising an ice maker arranged in a freezing chamber of the refrigerating-freezing device, a water storage box for providing water for ice-making of the ice maker, a water delivery pipeline connected between the ice maker and the water storage box, and a heating device for selectively heating the water delivery pipeline, the refrigerating-freezing device further comprising:

[0024] The control device comprises a processor and a memory, the memory stores a machine executable program, and the machine executable program is executed by the processor to implement the control method of any one of the above-mentioned schemes.

[0025] The inventors recognized that the factors influencing ice blockage in the water supply pipeline and condensation on the back of the refrigeration and freezing unit mainly include the ambient humidity of the external environment, the set temperature of the freezer compartment, the freezing mode of the freezer compartment (i.e., the freezing speed), the start / stop status of the compressor, and whether the ice maker is operating normally. Therefore, the refrigeration and freezing unit of this invention adjusts the operating rate of the heating device within a preset time period according to its preset parameters (one or more of ambient humidity, set temperature of the freezer compartment, freezing mode, compressor start / stop status, and ice maker operating status). This ensures that the operating time of the heating device matches the parameters of the refrigeration and freezing unit. On the one hand, this avoids unnecessary heat generation from excessively long heating device startup times, which could lead to a large temperature rise in the freezer compartment and reduce the energy consumption of the refrigeration and freezing unit. On the other hand, it also avoids ice blockage in the water supply pipeline caused by excessively short heating device startup times. In other words, this invention minimizes the operating rate of the heating device while ensuring that ice blockage does not occur in the water supply pipeline and condensation does not form on the back of the refrigeration and freezing unit, thereby reducing the energy consumption of the refrigeration and freezing unit.

[0026] Furthermore, without adding any additional accessories, this invention automatically adjusts the operating rate of the heating device by monitoring the preset reference of the refrigeration and freezing device. This does not increase the hardware cost of the refrigeration and freezing device, nor does it require any changes to the structure of the refrigeration and freezing device, thus reducing the energy consumption of the refrigeration and freezing device in a very simple way.

[0037] This invention first provides a control method for a refrigeration and freezing device. Figure 1This is a schematic structural diagram of a refrigeration and freezing apparatus according to an embodiment of the present invention. The refrigeration and freezing apparatus 1 of the present invention includes an ice maker 21 disposed in its freezing chamber 12, a water storage box 22 for providing ice-making water to the ice maker 21, a water supply pipeline 23 connected between the ice maker 21 and the water storage box 22, and a heating device 24 for selectively heating the water supply pipeline 23.

[0038] It is understandable that the freezer compartment 12 of the refrigeration and freezing device 1 is a storage room with a frozen storage environment, and the temperature inside can usually reach -24℃ to -18℃.

[0039] Furthermore, the refrigeration and freezing device 1 may also include a refrigerator compartment 11 with a refrigerated storage environment, the temperature of which can typically reach 0–8°C. A water storage box 22 may be installed in the refrigerator compartment 11.

[0040] Specifically, both the refrigerator compartment 11 and the freezer compartment 12 are confined within the cabinet 10.

[0041] Figure 2 This is a schematic flowchart of a control method for a refrigeration and freezing apparatus according to an embodiment of the present invention. See also Figure 2 The control method of the refrigeration and freezing apparatus of the present invention includes:

[0042] Step S10: Obtain preset parameters of the refrigeration and freezing device 1; these preset parameters include one or more of the following: ambient humidity of the external environment where the refrigeration and freezing device 1 is located, set temperature of the freezer compartment 12, freezing mode of the freezer compartment 12, start / stop status of the compressor of the refrigeration and freezing device 1, and ice-making status of the ice maker 21; and

[0043] Step S20: Adjust the operating rate of the heating device 24 within a preset time period according to preset parameters.

[0044] The inventors recognized that the factors affecting ice blockage in the water supply pipe 23 and condensation on the back of the refrigeration and freezing device 1 mainly include the ambient humidity of the external environment where the refrigeration and freezing device 1 is located, the set temperature of the freezer compartment 12, the freezing mode of the freezer compartment 12 (i.e., the freezing speed), the start and stop status of the compressor, and whether the ice maker 21 is in normal ice-making status, etc.

[0045] Therefore, the refrigeration and freezing device 1 of the present invention adjusts the operating rate of the heating device 24 within a preset time period according to its preset parameters (one or more of ambient humidity, freezer compartment set temperature, freezing mode, compressor start / stop status, and ice-making status of the ice maker), so that the operating time of the heating device 24 matches the parameters of the refrigeration and freezing device 1. On the one hand, this avoids unnecessary heat generation caused by the heating device 24 operating for too long, resulting in a large temperature rise in the freezer compartment 12, thus reducing the power consumption of the refrigeration and freezing device 1. On the other hand, it also avoids the phenomenon of ice blockage in the water supply pipe 23 caused by the heating device 24 operating for too short a time. In other words, the present invention minimizes the operating rate of the heating device 24 as much as possible while ensuring that the water supply pipe 23 does not become blocked and that condensation does not form on the back of the refrigeration and freezing device 1, thereby reducing the energy consumption of the refrigeration and freezing device 1.

[0046] Furthermore, without adding any additional accessories, the present invention automatically adjusts the operating rate of the heating device 24 by monitoring the preset reference of the refrigeration and freezing device 1. This does not increase the hardware cost of the refrigeration and freezing device 1, nor does it require any changes to the structure of the refrigeration and freezing device 1. In a very simple way, it avoids ice blockage in the water supply pipe 23, avoids condensation on the back of the refrigeration and freezing device 1, and reduces the energy consumption of the refrigeration and freezing device 1.

[0047] Understandably, the operating rate of the heating device 24 can be expressed as a percentage. For example, an operating rate of 50% means that within a preset time period, the heating device 24 is on for 50% of the time and off for 50% of the time.

[0048] Figure 3 This is a schematic flowchart of a control method for a refrigeration and freezing apparatus according to another embodiment of the present invention. See also Figure 3 The control method of the refrigeration and freezing apparatus of the present invention includes:

[0049] Step S10: Obtain the preset parameters of the refrigeration and freezing device 1;

[0050] Step S21: Search the preset power-on rate table to find the target power-on rate that matches the preset parameters; and

[0051] Step S22: Control the operation of heating device 24 according to the target operating rate.

[0052] In other words, step S20, which adjusts the operating rate of the heating device within a preset time period according to preset parameters, may specifically include:

[0053] Step S21: Search the preset power-on rate table to find the target power-on rate that matches the preset parameters; and

[0054] Step S22: Control the operation of heating device 24 according to the target operating rate.

[0055] This invention provides a preset start-up rate table for the heating device 24, which facilitates direct matching of the corresponding target start-up rate based on the obtained preset parameters. This is simple, quick, and improves response speed, thereby enhancing control accuracy.

[0056] In some embodiments, the freezing mode of the freezer compartment 12 may include a quick-freeze mode and a regular freezing mode. Specifically, the freezing speed of the freezer compartment 12 in quick-freeze mode is higher than that in regular freezing mode. That is, in quick-freeze mode, the freezer compartment 12 requires more cooling capacity.

[0057] In some embodiments, the ice maker 21 has two ice-making states: a normal ice-making state and an abnormal ice-making state. In the normal ice-making state, the ice maker 21 operates normally and produces ice. In the abnormal ice-making state, the ice maker 21 cannot operate normally and cannot produce ice.

[0058] Specifically, abnormal ice-making status of the ice maker may include, for example, detection of empty water tank 22, abnormal stop of ice making, or no ice maker.

[0059] In some embodiments, when the set temperature of the freezer 12, the freezing mode of the freezer 12, and the start / stop state of the compressor are the same, the target start-up rate of the heating device 24 when the ambient humidity is higher than the preset humidity threshold and the ice maker 21 is in an abnormal ice-making state is greater than the target start-up rate of the heating device 24 when the ambient humidity is lower than the preset humidity threshold and the ice maker 21 is in an abnormal ice-making state.

[0060] When the ice maker 21 is in an abnormal ice-making state, it does not perform ice-making operations; that is, no water flows from the water storage box 22 through the water supply pipe 23 to the ice maker 21. At this time, the operating rate of the heating device 24 is primarily considered in relation to condensation. Furthermore, higher ambient humidity makes condensation more likely. Therefore, the target operating rate of the heating device 24 when the ambient humidity is higher than the preset humidity threshold is greater than the target operating rate when the ambient humidity is lower than the preset humidity threshold.

[0061] In some embodiments, when the set temperature of the freezer 12, the freezing mode of the freezer 12, and the start / stop state of the compressor are the same, the target operating rate of the heating device 24 when the ambient humidity is higher than the preset humidity threshold and the ice maker 21 is in normal ice-making state is equal to the target operating rate of the heating device 24 when the ambient humidity is lower than the preset humidity threshold and the ice maker 21 is in normal ice-making state.

[0062] When the ice maker 21 is in normal ice-making mode, it needs to perform the ice-making action, which means that water is intermittently supplied from the water storage box 22 through the water supply pipe 23 to the ice maker 21. At this time, the operating rate of the heating device 24 mainly considers the problem of ice blockage in the water supply pipe 23, while the ambient humidity level has almost no relation to the ice blockage in the water supply pipe 23. Therefore, the target operating rate of the heating device 24 when the ambient humidity is higher than the preset humidity threshold is the same as the target operating rate of the heating device 24 when the ambient humidity is lower than the preset humidity threshold.

[0063] In some embodiments, under the same conditions of ambient humidity and compressor start / stop status, the target operating rate of the heating device 24 when the freezer compartment 12 is in normal freezing mode and the ice maker 21 is in normal ice-making state is lower than the target operating rate of the heating device 24 when the freezer compartment 12 is in quick-freezing mode and the ice maker is in normal ice-making state.

[0064] When the ice maker 21 is in normal ice-making mode, it needs to perform the ice-making action, which means that water is intermittently supplied from the water storage box 22 through the water supply pipe 23 to the ice maker 21. At this time, the operating rate of the heating device 24 mainly considers the problem of ice blockage in the water supply pipe 23. The cooling capacity required by the freezer compartment 12 in normal freezing mode is less than that required in quick-freezing mode; that is, the temperature of the freezer compartment 12 in normal freezing mode is slightly higher than that in quick-freezing mode. Therefore, the target operating rate of the heating device 24 in the freezer compartment 12 in normal freezing mode is lower than the target operating rate required in quick-freezing mode.

[0065] In some embodiments, when the freezer compartment 12 is in quick-freeze mode and the ice maker 21 is in normal ice-making mode, the target operating rate of the heating device 24 is the preset maximum operating rate.

[0066] In quick-freeze mode, freezer compartment 12 requires more cooling and a lower temperature. When ice maker 21 is in normal ice-making mode, it needs to perform ice-making operations, which means water is intermittently supplied from water tank 22 through water supply pipe 23 to ice maker 21. Therefore, it is essential to ensure that water supply pipe 23 does not become blocked with ice, otherwise it will affect the normal ice-making of ice maker 21. At this time, the operating rate of heating device 24 mainly considers the problem of ice blockage in water supply pipe 23, and the temperature of freezer compartment 12 is even lower. Therefore, the target operating rate of heating device 24 when freezer compartment 12 is in quick-freeze mode and ice maker 21 is in normal ice-making mode is the preset maximum operating rate.

[0067] Specifically, the preset maximum power-on rate can be any percentage between 65% and 75%.

[0068] In some embodiments, when the ambient humidity is lower than a preset humidity threshold, the freezer 12 is in normal cooling mode, the set temperature of the freezer 12 is higher than a preset temperature threshold, and the ice maker 21 is in an abnormal ice-making state, the target start-up rate of the heating device 24 is zero.

[0069] When the ambient humidity is below the preset humidity threshold, it indicates that the ambient humidity is relatively low. The set temperature of the freezer compartment 12 is higher than the preset temperature threshold, indicating that the set temperature of the freezer compartment 12 is slightly high, meaning that the water supply pipe 23 is in a relatively high-temperature environment. Therefore, condensation is less likely to form on the back of the refrigeration and freezing unit 1. The ice maker 21 is in an abnormal ice-making state, meaning that the ice maker 21 is not making ice and does not need to supply water to it. At this time, there is no need to consider the issue of ice blockage in the water supply pipe 23. Therefore, in this state, there is no need to heat the water supply pipe 23 to avoid heat transfer to the freezer compartment 12, which could cause a significant temperature rise in the freezer compartment 12. Therefore, the operating rate of the heating device 24 is zero, minimizing the energy consumption of the refrigeration and freezing unit 1.

[0070] In some embodiments, when the ambient humidity is lower than a preset humidity threshold, the freezer 12 is in normal cooling mode and the set temperature of the freezer 12 is lower than a preset temperature threshold, and the ice maker 21 is in an abnormal ice-making state, or when the ambient humidity is lower than a preset humidity threshold, the freezer 12 is in quick-freezing mode and the ice maker 21 is in an abnormal ice-making state, the target start-up rate of the heating device 24 when the compressor is in the running state is greater than the target start-up rate when the compressor is in the stopped state.

[0071] When the ambient humidity is below the preset humidity threshold, the humidity is relatively low, and condensation is less likely to occur. When the set temperature of the freezer compartment 12 is below the preset temperature threshold or when the freezer compartment 12 is in quick-freeze mode, the required cooling capacity of the freezer compartment 12 is relatively large, meaning the temperature of the freezer compartment 12 is relatively low. Since the compressor continuously supplies cooling capacity to the freezer compartment 12 during operation, the water supply pipe 23 is more prone to ice blockage. Therefore, the target operating rate of the heating device 24 when the compressor is running must be greater than the target operating rate when the compressor is stopped to completely prevent ice blockage in the water supply pipe 23.

[0072] In some embodiments, when the ambient humidity is higher than a preset humidity threshold, except when the freezer 12 is in quick-freeze mode and the ice maker 21 is in normal ice-making state, the target start-up rate of the heating device 24 when the compressor is running is greater than the target start-up rate when the compressor is stopped.

[0073] In quick-freeze mode, freezer compartment 12 requires more cooling capacity and a lower temperature. When ice maker 21 is in normal ice-making mode, it needs to perform ice-making operations, which means water is intermittently supplied from water storage box 22 through water supply pipe 23 to ice maker 21. Therefore, it is essential to ensure that water supply pipe 23 does not become blocked with ice, otherwise it will affect the normal ice-making of ice maker 21. Therefore, the target operating rate of heating device 24 when freezer compartment 12 is in quick-freeze mode and ice maker 21 is in normal ice-making mode is the preset maximum operating rate, regardless of the compressor's start / stop status. In other cases, the compressor's start / stop status must be considered, because the compressor continuously supplies cooling capacity to freezer compartment 12 during operation, making water supply pipe 23 more prone to ice blockage. Therefore, the target operating rate of heating device 24 when the compressor is running must be greater than the target operating rate when the compressor is stopped to completely prevent ice blockage in water supply pipe 23.

[0075] Specifically, the refrigeration and freezing apparatus 1 also includes a control device 40, which includes a processor 41 and a memory 42. The memory 42 stores a machine-executable program 43, and when the machine-executable program 43 is executed by the processor 41, it is used to implement the control method described in any of the above embodiments.
