Description
Technical Field
The present invention relates to a refrigeration technology, and more particularly, to a refrigeration and freezing apparatus and a control method thereof.
Background
With the development of technology and increasing demands of users, some refrigerators now have an ice making function. In particular, some refrigerators having an ice making function generally include a water storage box, a water pump, a water delivery pipe, an ice maker, a driving device, and an ice storage box. Wherein the water storage box is used for storing water. One end of the water conveying pipeline is communicated with the water storage box, and the other end of the water conveying pipeline is communicated with the ice maker. The water pump is used for pumping the water in the water storage box into the water delivery pipeline and delivering the water into the ice machine through the water delivery pipeline. The ice maker is used for cooling water therein into ice. The ice bank is located below the ice maker and is used for storing ice cubes.
In the ice making process of the ice making refrigerator adopting the water storage box to supply water, a water conveying pipeline is required to be connected with the water storage box and the ice making machine. The part of the water delivery pipeline in the freezing chamber is extremely easy to be frozen due to low temperature, so that the water delivery pipeline is blocked by ice. And the temperature of the water delivery pipeline is lower, and cold energy can be transmitted to the back of the refrigerator through the pipe body, so that the rubber parts of the back of the refrigerator and the back plates nearby generate condensation.

To solve the problems posed in the background section, the applicant has appreciated that it is possible to solve the problems by heating the water transport line. The heating wire is arranged on the water conveying pipeline to effectively prevent the problems of freezing of the water conveying pipeline and condensation of the back of the refrigerator, but if the heating wire is simply and coarsely operated, the heating wire can directly waste electric quantity, and the temperature of the freezing chamber can be increased due to the fact that extra heat is generated, more cold energy is needed to adjust the temperature in the freezing chamber, and indirect waste of the electric quantity is caused.

Optionally, under the condition that the ambient humidity and the start-stop state of the compressor are the same, the target opening probability corresponding to the heating device when the freezing chamber is in a normal freezing mode and the ice maker is in a normal ice making state is lower than the target opening probability corresponding to the heating device when the freezing chamber is in a quick freezing mode and the ice maker is in a normal ice making state.
Optionally, when the freezing chamber is in a quick-freezing mode and the ice maker is in a normal ice making state, the target opening probabilities of the heating device are all preset highest opening probabilities.
Optionally, when the ambient humidity is lower than a preset humidity threshold, the freezing chamber is in a normal refrigeration mode, the set temperature of the freezing chamber is higher than a preset temperature threshold, and the ice maker is in an abnormal ice making state, the target opening rate of the heating device is zero.
Optionally, when the ambient humidity is lower than a preset humidity threshold, the freezing chamber is in a normal refrigeration mode, the set temperature of the freezing chamber is lower than a preset temperature threshold, and the ice maker is in an abnormal ice making state, or when the ambient humidity is lower than the preset humidity threshold, the freezing chamber is in a quick freezing mode, and the ice maker is in an abnormal ice making state, the target opening probability corresponding to the heating device when the compressor is in an operating state is greater than the target opening probability corresponding to the compressor when the compressor is in a stop state.
Optionally, when the ambient humidity is higher than a preset humidity threshold, the target opening probability corresponding to the heating device when the compressor is in the running state is greater than the target opening probability corresponding to the compressor in the stop state except that the freezing chamber is in the quick-freezing mode and the ice maker is in the normal ice making state.

The inventor realizes that the influence factors of ice blockage in the water conveying pipeline and condensation on the back of the refrigerating and freezing device mainly comprise the environment humidity of the external environment where the refrigerating and freezing device is positioned, the set temperature of the freezing chamber, the freezing mode (namely the freezing speed), the start-stop state of the compressor, whether the ice making state of the ice maker is normal or not and the like. Therefore, the refrigerating and freezing device adjusts the opening probability of the heating device in a preset time period according to preset parameters (one or more of environment humidity, freezing chamber set temperature, freezing mode, compressor start-stop state and ice making state of the ice maker) so that the start-up time of the heating device is matched with the parameters of the refrigerating and freezing device, on one hand, the situation that unnecessary heat is generated when the heating device is started for too long to cause the freezing chamber to generate larger temperature rise can be avoided, and the electric energy consumed by the refrigerating and freezing device is reduced; on the other hand, the phenomenon that the water conveying pipeline is blocked by ice due to the fact that the starting time of the heating device is too short can be avoided. That is, the invention reduces the turn-on probability of the heating device as much as possible under the condition that the water conveying pipeline is ensured not to generate ice blockage and the back of the refrigerating and freezing device is ensured not to generate condensation, thereby reducing the energy consumption of the refrigerating and freezing device.
On the basis of not adding extra accessories, the invention automatically adjusts the opening rate of the heating device by monitoring the preset reference of the refrigerating and freezing device, does not increase the hardware cost of the refrigerating and freezing device, does not need to change the structure of the refrigerating and freezing device, and reduces the energy consumption of the refrigerating and freezing device in a very simple way.

The present invention first provides a control method of a refrigerating and freezing apparatus, and fig. 1 is a schematic structural diagram of a refrigerating and freezing apparatus according to an embodiment of the present invention. The refrigerating and freezing apparatus 1 of the present invention includes an ice maker 21 provided in a freezing chamber 12 thereof, a water storage tank 22 for supplying ice making water to the ice maker 21, a water pipe 23 connected between the ice maker 21 and the water storage tank 22, and a heating device 24 for selectively heating the water pipe 23.
It will be appreciated that the freezer compartment 12 of the refrigeration and freezer 1 is a storage compartment having a refrigerated storage environment in which temperatures typically can reach-24 ℃ to-18 ℃.
Further, the refrigerating and freezing device 1 may further comprise a refrigerating chamber 11 having a refrigerating storage environment, and the temperature in the refrigerating chamber 11 may be generally 0 to 8 ℃. The water storage box 22 may be provided in the refrigerating chamber 11.
Specifically, a refrigerating compartment 11 and a freezing compartment 12 are each defined in the cabinet 10.
Fig. 2 is a schematic flow chart of a control method of a refrigerating and freezing apparatus according to an embodiment of the present invention. Referring to fig. 2, the control method of the refrigerating and freezing apparatus of the present invention includes:
step S10, acquiring preset parameters of the refrigeration and freezing device 1; the preset parameters include one or more of an ambient humidity of an external environment in which the refrigerating and freezing apparatus 1 is located, a set temperature of the freezing chamber 12, a freezing mode of the freezing chamber 12, a start-stop state of a compressor of the refrigerating and freezing apparatus 1, and an ice making state of the ice maker 21; and
in step S20, the turn-on probability of the heating device 24 in the preset time period is adjusted according to the preset parameters.
The inventors have recognized that factors affecting ice blockage in the water supply line 23 and condensation on the back of the refrigerator-freezer 1 mainly include the ambient humidity of the external environment in which the refrigerator-freezer 1 is located, the set temperature of the freezer compartment 12, the freezing mode (i.e., the freezing speed) of the freezer compartment 12, the on-off state of the compressor, whether the ice making state of the icemaker 21 is normal, and the like.
Therefore, the refrigerating and freezing device 1 of the present invention adjusts the opening rate of the heating device 24 in a preset time period according to preset parameters (one or more of the ambient humidity, the set temperature of the freezing chamber, the freezing mode, the start-stop state of the compressor and the ice making state of the ice maker) so that the start-up time of the heating device 24 is matched with the parameters of the refrigerating and freezing device 1, on one hand, it can be avoided that unnecessary heat is generated due to the overlong start-up time of the heating device 24 to cause the freezing chamber 12 to generate a larger temperature rise, and the electric energy consumed by the refrigerating and freezing device 1 is reduced; on the other hand, the phenomenon that the water conveying pipeline 23 is blocked due to the fact that the starting time of the heating device 24 is too short can be avoided. That is, the present invention reduces the turn-on probability of the heating device 24 as much as possible while ensuring that the water supply line 23 is not blocked by ice and the back of the refrigerating and freezing apparatus 1 is not condensed, thereby reducing the power consumption of the refrigerating and freezing apparatus 1.
On the basis of not adding extra accessories, the invention automatically adjusts the opening rate of the heating device 24 by monitoring the preset reference of the refrigerating and freezing device 1, does not increase the hardware cost of the refrigerating and freezing device 1, does not need to change the structure of the refrigerating and freezing device 1, avoids ice blockage of the water conveying pipeline 23, avoids condensation on the back of the refrigerating and freezing device 1 and reduces the energy consumption of the refrigerating and freezing device 1 in a very simple way.
It will be appreciated that the turn-on probability of the heating device 24 may be expressed in terms of a percentage. For example, when the on-rate is 50%, it means that the heating device 24 is turned on for 50% and turned off for 50% in the preset time period.
Fig. 3 is a schematic flow chart of a control method of a refrigerating and freezing apparatus according to another embodiment of the present invention. Referring to fig. 3, the control method of the refrigerating and freezing apparatus of the present invention includes:
step S10, acquiring preset parameters of the refrigeration and freezing device 1;
step S21, searching a preset starting rate table to find out a target starting rate matched with preset parameters; and
step S22, the heating device 24 is controlled to operate according to the target on-rate.
That is, the step S20 of adjusting the turn-on probability of the heating device in the preset time period according to the preset parameters may specifically include:
step S21, searching a preset starting rate table to find out a target starting rate matched with preset parameters; and
step S22, the heating device 24 is controlled to operate according to the target on-rate.
According to the invention, the preset starting rate table is set for the heating device 24, so that the corresponding target starting rate can be conveniently and directly matched according to the acquired preset parameters, the method is simple and quick, the response speed is improved, and the control precision is improved.
In some embodiments, the freezing mode of the freezer compartment 12 may include a quick-freeze mode and a conventional freezing mode. Specifically, the freezing speed of the freezing chamber 12 in the quick freezing mode is higher than that in the conventional freezing mode. That is, in the quick-freeze mode, more cold is required for the freezing chamber 12.
In some embodiments, the ice making state of the ice maker 21 includes a normal ice making state and an abnormal ice making state. In a normal ice making state, the ice maker 21 can normally operate and make ice cubes. In an abnormal ice making state, the ice maker 21 cannot normally operate, and ice cubes cannot be made.
Specifically, the abnormal ice making state of the ice maker may include, for example, empty detection of the water storage box 22, abnormal stop of ice making, no ice maker, etc.
In some embodiments, when the set temperature of the freezing chamber 12, the freezing mode of the freezing chamber 12, and the on-off state of the compressor are the same, the target on-rate of the heating device 24 when the ambient humidity is higher than the preset humidity threshold and the ice maker 21 is in the abnormal ice making state is greater than the target on-rate of the heating device 24 when the ambient humidity is lower than the preset humidity threshold and the ice maker 21 is in the abnormal ice making state.
When the ice maker 21 is in an abnormal ice making state, the ice making action is not performed, that is, no flowing water is delivered from the water storage box 22 to the ice maker 21 through the water delivery pipe 23, and at this time, the start-up rate of the heating device 24 mainly considers the condensation problem. And, the higher the ambient humidity, the more likely the condensation is generated. Therefore, the target on-probability corresponding to the heating device 24 when the ambient humidity is higher than the preset humidity threshold is greater than the target on-probability corresponding to the heating device 24 when the ambient humidity is lower than the preset humidity threshold.
In some embodiments, when the set temperature of the freezing chamber 12, the freezing mode of the freezing chamber 12, and the on-off state of the compressor are the same, the target on-rate corresponding to the heating device 24 when the ambient humidity is higher than the preset humidity threshold and the ice maker 21 is in the normal ice making state is equal to the target on-rate corresponding to the heating device 24 when the ambient humidity is lower than the preset humidity threshold and the ice maker 21 is in the normal ice making state.
When the ice maker 21 is in a normal ice making state, the ice making operation needs to be performed, that is, water is intermittently transferred from the water storage box 22 to the ice maker 21 through the water transfer pipeline 23, at this time, the starting-up rate of the heating device 24 mainly considers the ice blockage problem of the water transfer pipeline 23, and the height of the ambient humidity is almost irrelevant to the ice blockage of the water transfer pipeline 23. Therefore, the target on-rate corresponding to the heating device 24 when the ambient humidity is higher than the preset humidity threshold is the same as the target on-rate corresponding to the heating device 24 when the ambient humidity is lower than the preset humidity threshold.
In some embodiments, with the same ambient humidity, compressor start-stop conditions, the target opening probability for the heating device 24 when the freezer compartment 12 is in the normal freezing mode and the ice maker 21 is in the normal ice making state is lower than the target opening probability for the heating device 24 when the freezer compartment 12 is in the quick-freeze mode and the ice maker is in the normal ice making state.
When the ice maker 21 is in a normal ice making state, the ice making operation needs to be performed, that is, water is intermittently transferred from the water storage box 22 to the ice maker 21 through the water transfer pipeline 23, and at this time, the starting-up rate of the heating device 24 mainly considers the ice blockage problem of the water transfer pipeline 23. And the amount of cooling required by the freezing chamber 12 in the normal freezing mode is less than the amount of cooling required by the freezing chamber 12 in the quick freezing mode, i.e., the temperature of the freezing chamber 12 in the normal freezing mode is slightly higher than the temperature of the freezing chamber 12 in the quick freezing mode. Thus, the target on-rate required by the heating device 24 in the normal freezing mode of the freezing chamber 12 is lower than the target on-rate required by the freezing chamber 12 in the quick-freeze mode.
In some embodiments, when the freezing chamber 12 is in the quick-freezing mode and the ice maker 21 is in the normal ice making state, the target opening probability of the heating device 24 is the preset highest opening probability.
The freezing chamber 12 requires more cold and has lower temperature in the quick freezing mode; when the ice maker 21 is in a normal ice making state, an ice making operation is required to be performed, that is, water is intermittently supplied from the water storage tank 22 to the ice maker 21 through the water supply line 23. Therefore, it must be ensured that the water delivery line 23 is not capable of generating ice blockage, which would otherwise affect the normal ice making of the ice maker 21. At this time, the start-up rate of the heating device 24 mainly considers the ice blockage problem of the water delivery pipe 23, and the temperature of the freezing chamber 12 is lower. Therefore, the target opening rates of the heating device 24 in the freezing chamber 12 in the quick freezing mode and the ice maker 21 in the normal ice making state are all preset highest opening rates.
Specifically, the preset maximum power-on rate may be any percentage ranging from 65% to 75%, for example.
In some embodiments, the target on-rate of the heating device 24 is zero when the ambient humidity is below a preset humidity threshold, the freezing chamber 12 is in a normal cooling mode, the set temperature of the freezing chamber 12 is above a preset temperature threshold, and the ice maker 21 is in an abnormal ice making state.
When the ambient humidity is lower than the preset humidity threshold, the ambient humidity is relatively lower. The set temperature of the freezing chamber 12 being higher than the preset temperature threshold value indicates that the set temperature of the freezing chamber 12 is slightly higher, i.e., the water delivery pipe 23 is in an environment having a relatively slightly higher temperature. Therefore, the back of the refrigeration and freezing apparatus 1 is not likely to form dew. The ice maker 21 is in an abnormal ice making state, i.e., the ice maker 21 does not make ice, and there is no need to convey water to the ice maker 21. At this time, the water pipe 23 does not need to consider the problem of ice blockage. For this reason, in this state, it is not necessary to heat the water pipe 23 to avoid the heat transfer to the freezing chamber 12 to cause the temperature rise of the freezing chamber 12 to be serious, and thus, the turn-on probability of the heating device 24 is zero, and the power consumption of the refrigerating and freezing device 1 is reduced as much as possible.
In some embodiments, when the ambient humidity is below a preset humidity threshold, the freezing chamber 12 is in the normal cooling mode and the set temperature of the freezing chamber 12 is below a preset temperature threshold, and the ice maker 21 is in an abnormal ice making state, or when the ambient humidity is below a preset humidity threshold, the freezing chamber 12 is in the quick freezing mode, and the ice maker 21 is in an abnormal ice making state, the target on-probability corresponding to the heating device 24 when the compressor is in the running state is greater than the target on-probability corresponding to the compressor is in the stopped state.
When the ambient humidity is lower than a preset humidity threshold, the ambient humidity is relatively low, and condensation is not easy to generate. When the set temperature of the freezing chamber 12 is lower than the preset temperature threshold or the freezing chamber 12 is in the quick-freezing mode, more cold is required for the freezing chamber 12, i.e., the temperature of the freezing chamber 12 is lower. The compressor continuously delivers cold to the freezing chamber 12 during operation, and the water delivery pipeline 23 is more prone to ice blockage, so that the target opening rate of the heating device 24 when the compressor is in an operation state must be greater than the target opening rate of the heating device when the compressor is in a stop state, and thus ice blockage of the water delivery pipeline 23 can be thoroughly avoided.
In some embodiments, when the ambient humidity is above the preset humidity threshold, the heating device 24 corresponds to a greater target on-rate when the compressor is in an operational state than when the compressor is in a stopped state, except that the freezer compartment 12 is in a quick-freeze mode and the ice maker 21 is in a normal ice-making state.
The freezing chamber 12 requires more cold and has lower temperature in the quick freezing mode; when the ice maker 21 is in a normal ice making state, an ice making operation is required to be performed, that is, water is intermittently supplied from the water storage tank 22 to the ice maker 21 through the water supply line 23. Therefore, it must be ensured that the water delivery line 23 is not capable of generating ice blockage, which would otherwise affect the normal ice making of the ice maker 21. Therefore, the target opening rates of the heating device 24 in the freezing chamber 12 in the quick freezing mode and the ice maker 21 in the normal ice making state are all preset maximum opening rates, regardless of the start-stop state of the compressor. In addition, in other cases, the start-stop state of the compressor needs to be considered, because the compressor is continuously delivering cold to the freezing chamber 12 when running, the water pipe 23 is more prone to ice blockage, so the target opening probability of the heating device 24 when the compressor is in the running state must be greater than the target opening probability of the heating device when the compressor is in the stop state, and thus the water pipe 23 can be thoroughly prevented from ice blockage.
