Detailed Description
The present invention will be described in detail below with reference to specific embodiments shown in the accompanying drawings. These embodiments are not intended to limit the present invention, and structural, methodological, or functional changes in accordance with the embodiments are within the scope of the present invention.
It will be understood that terms such as "upper," "lower," "outer," "inner," and the like, used herein to denote relative spatial positions, are used for ease of description to describe one element or feature's relationship to another element or feature as illustrated in the figures. The spatially relative positional terms may be intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures.
Referring to fig. 1 to 3, the refrigeration apparatus includes a cabinet 10, a door 20 movably connected to the cabinet, and a refrigeration system. The cabinet 10 defines a storage compartment and a door body that opens or closes the storage compartment. The storage compartments may include a refrigerating compartment 11, a freezing compartment 12, a temperature-changing compartment, or the like. The door 20 is provided with an ice making chamber 21 and an ice maker (not shown) disposed in the ice making chamber 21. The refrigerating system supplies cold energy to the storage compartment and the ice making compartment 21.
Specifically, the refrigeration system includes a compressor 31, a condenser, a capillary tube, an evaporator, and the like, which are connected by a pipeline to form a refrigeration circuit. In this embodiment, the storage compartment and the ice making compartment 21 are respectively and independently cooled, so that a first cooling branch and a second cooling branch are formed in the refrigeration system and are arranged in parallel.
In the present embodiment, the first cooling branch and the second cooling branch are connected in parallel to the inlet side of the compressor 31 and the outlet side of the condenser. The first cold supply branch is used for providing cold energy for the storage compartment, and the second cold supply branch is used for providing cold energy for the ice making compartment 21.
Specifically, the first cooling branch includes a freezing capillary tube 313 and a freezing evaporator 312 connected to an outlet side of the freezing capillary tube 313, wherein the freezing capillary tube 313 is connected to an outlet side of the condenser, and the freezing evaporator 312 is connected to an inlet side of the compressor 31. The freezing evaporator 312 is disposed in the storage compartment to supply cold to the storage compartment. The second cooling branch includes an ice making capillary tube 323 and an ice making evaporator 322 connected to an outlet side of the ice making capillary tube 323, the ice making evaporator 322 is disposed in the ice making chamber 21, wherein the ice making capillary tube 323 is connected to an outlet side of the condenser, and the ice making evaporator 322 is connected to an inlet side of the compressor 31. That is, after entering the condenser for cooling from the compressor 31, the refrigerant may selectively enter the freezing capillary tube 313 and the ice making capillary tube 323, the refrigerant returns to the compressor 31 after reaching the freezing evaporator 312 through the freezing capillary tube 313, and the refrigerant returns to the ice making evaporator 322 through the ice making capillary tube 323 and then also returns to the compressor 31. Therefore, the refrigerating processes of the storage compartment and the ice making chamber 21 can be independently controlled.
In addition, a first solenoid valve 35 is connected to the outlet side of the condenser, and the inlet side of the first cooling branch and the inlet side of the second cooling branch are both connected to the first solenoid valve 35, so that one or more cooling branches can be selectively closed to limit the flow of refrigerant therein, thereby performing independent control on the first cooling branch and the second cooling branch. In the present embodiment, the first solenoid valve 35 is configured as a one-in two-out valve including one inlet A1 and two outlets, i.e., an ice making outlet B1 and a cooling outlet C1.
In order to further optimize the refrigeration equipment, the refrigeration system of the refrigeration equipment further comprises a dew removing pipe 34 connected between the condenser and the first electromagnetic valve 35, the condenser comprises two back condensers 32 and side plate condensers 33 which are connected in series, and the two condensers are arranged at different positions of the refrigeration equipment, so that the heat dissipation effect is improved.
In the above embodiment, when the second cooling branch operates alone, the evaporation area of the refrigerant pipe in the ice making evaporator 322 is small due to the small ice making chamber space, which inevitably results in too much refrigerant in the refrigerant pipe, and there is a risk of damaging the compressor 31 by liquid impact. In addition, when the first cooling branch operates alone or the first cooling branch and the second cooling branch operate simultaneously, the amount of the refrigerant required in the refrigeration loop of the first cooling branch and/or the second cooling branch is increased greatly, which may cause the situation that the first cooling branch and/or the second cooling branch is in a liquid shortage state, and affect the refrigeration effect of the refrigeration equipment.
To this end, the present invention provides another preferred embodiment, and referring to fig. 2, in this embodiment, the refrigerating system of the refrigerating apparatus further includes a liquid storage device 37 connected between the condenser and the dew-removing pipe 34, and the amount of the refrigerant stored in the liquid storage device 37 can be quantitatively adjusted, and is proportionally adjusted according to the maximum volume of the liquid storage device 37.
Therefore, in this embodiment, a liquid storage device 37 with an adjustable volume is connected between the condenser and the dew-removing pipe 34, and the volume of the liquid storage device 37 is adjusted to store a certain amount of refrigerant, so as to adjust the amount of refrigerant in the first cooling branch and/or the second cooling branch, thereby meeting the requirement of refrigerant when different cooling branches operate.
Specifically, referring to fig. 3, the liquid storage device 37 includes a liquid storage container 372 having a liquid storage chamber 371 for accommodating refrigerant, a first liquid storage pipe 373 and a first liquid outlet pipe 374 connecting the inside and the outside of the liquid storage container 372, a baffle 375 adjustably disposed in the liquid storage chamber 374, and a driving mechanism for driving the baffle 375 to move up and down to adjust the actual volume of the liquid storage chamber 371, the driving mechanism includes a driving threaded column 376 rotatably disposed in the liquid storage container 372 and a driving motor 377 for driving the driving threaded column 376 to rotate, the driving baffle 375 is in threaded engagement with the driving threaded column 376, and the driving motor 377 is mounted on the liquid storage container 372. The driving screw column 376 can rotate under the driving of the driving motor 377 and drives the driving baffle 375 to move up and down in the liquid storage chamber 371, so as to change the amount of the refrigerant actually contained in the liquid storage device 37, and due to the fact that the driving baffle 375 and the driving screw column 376 are in threaded fit, the amount of the refrigerant stored in the liquid storage device 37 can be adjusted linearly, namely, the refrigerant is adjusted proportionally according to the maximum volume of the liquid storage device 37, and the structure arranged on the liquid storage device 37 forms a quantitative adjusting mechanism of the liquid storage device 37.
In this embodiment, a liquid storage device 37 is arranged between the inlet of the first cooling branch and the inlet of the second cooling branch and the outlet of the condenser, namely, a liquid storage device 37 is arranged on the whole cooling main line to adjust the amount of refrigerant participating in the refrigeration cycle in the whole cooling main line, so that the requirement of the refrigeration equipment for the refrigerant under different working states can be met, the condition that the refrigerant is too much or too little is avoided, the structure is simple, and the production and maintenance cost is low. When the first electromagnetic valve 35 is used for closing the first cooling branch or the second cooling branch, the liquid storage device 37 can also independently adjust the refrigerant for the first cooling branch or the second cooling branch. In addition, the liquid storage device 37 may also be disposed on the first cooling branch and/or the second cooling branch to directly regulate the refrigerant in the cooling branch. The volume of the liquid storage device 37 is adjusted based on the actually required cold quantity of the storage chamber and the ice making chamber 21, so that the situations that the compressor 31 is damaged by excessive liquid impact of the generated refrigerant and the refrigeration effect is influenced by too little refrigerant are avoided, and the actual requirements of the refrigerants of the first cooling branch and the second cooling branch are quantitatively met.
To sum up, the liquid storage device 37 can control the amount of the refrigerant which can be stored according to the amount of the actual refrigerant required on the first cooling branch and/or the second cooling branch, so as to accurately control the cooling capacity required by the storage compartment and the ice making compartment 21, and avoid the situations that the compressor 31 is damaged by too much liquid impact of the refrigerant in the cooling loop and the refrigeration effect is influenced by too little refrigerant.
The specific embodiment of the invention also relates to an ice making control method of the refrigeration equipment, and the composition and the function of the refrigeration system are as described above, and are not described again here.
Referring to fig. 4, the refrigeration apparatus provided in the above embodiment is further related to an ice making control method for the refrigeration apparatus, including the steps of:
s1, acquiring an ice making instruction;
s2, when an ice making instruction is obtained, the ice content in an ice bucket of the ice making machine is obtained, the amount of a refrigerant in a cold supply branch of the ice making machine is adjusted according to the ice content in the ice bucket, and then ice making is started;
and S3, stopping ice making when the information that the ice bucket is in the full ice state is obtained.
In the step S2, the ice content in the ice bucket of the ice maker is obtained through a weight sensor arranged in the refrigeration equipment, and in the step S3, whether the ice bucket is in a full ice state is obtained through a hall sensor arranged in the refrigeration equipment.
The content of ice in the ice bucket is judged through the weight sensor arranged in the refrigeration equipment, along with the difference of the content of ice in the ice bucket of the ice machine, different cold energy is required for radiation cooling, the amount of the refrigerant in the second cold supply branch is correspondingly adjusted to reach proper amount, and the condition that the refrigeration equipment cannot normally work when the generated refrigerant is insufficient or excessive is avoided. In the embodiment, whether the ice in the ice bucket reaches the full ice state is judged through the Hall sensor arranged in the refrigeration equipment, and ice making can be stopped after the full ice state is reached, so that the energy consumption of the refrigeration equipment is saved.
Further, in the step S2, in the ice making process, the ice content in the ice bucket of the ice maker is obtained in real time, and the amount of the refrigerant in the cooling branch is correspondingly adjusted according to the section where the ice content is located. When the refrigeration equipment is actually used for making ice, ice in the ice bucket may be gradually increased in the ice making process, or a user may take a certain amount of ice blocks, so that the content of the ice in the ice bucket may be changed in an indefinite amount at any time, and thus the content of the ice in the ice bucket of the ice maker needs to be obtained in real time, so that the accurate control of the amount of the refrigerant in the ice making process is improved.
Further, the amount of the refrigerant in the cooling branch decreases in proportion to the increase of the content of the ice in the ice bucket. With the increase of the ice content in the ice bucket of the ice maker, certain ice blocks are stored in the ice bucket, and the cold quantity required by further ice making is reduced, so that the amount of the refrigerant in the second cold supply branch can be reduced, and the compressor 31 is prevented from being damaged by excessive liquid impact of the refrigerant.
Specifically, the refrigeration equipment is provided with a liquid storage device which is connected in the cold supply branch and has an adjustable volume, in the step S2, the amount of refrigerant participating in the refrigeration cycle in the cold supply branch is adjusted through the liquid storage device, and the liquid storage device is provided with a quantitative adjusting mechanism which can realize the actual volume of the refrigeration equipment within the maximum volume range of the liquid storage device. In this embodiment, the liquid storage device 37 is connected between the inlets of the first cooling branch and the second cooling branch and the outlet of the condenser, and the amount of the refrigerant participating in the refrigeration cycle in the first cooling branch and/or the second cooling branch is controlled by storing the refrigerant in the liquid storage device 37, and the amount of the refrigerant participating in the refrigeration cycle in the first cooling branch and the second cooling branch is adjustable because the amount of the refrigerant stored in the liquid storage device 37 is adjustable.
At the beginning, whether ice making is started or not needs to be judged; if the refrigeration device is started, judging the ice content in the ice bucket according to a weight sensor in the refrigeration device, and controlling the capacity of the liquid storage device 37 for storing the refrigerant according to the ice content so as to achieve the purpose of adjusting the refrigerant amount in the second cooling branch; the above-mentioned action of judging ice content in the ice bucket is carried on in real time, can set up certain time interval to carry on periodically too; and the Hall sensor in the refrigeration equipment also judges whether the ice bucket is in a full ice state in real time, if not, the step S2 is controlled to be continuously carried out; and stopping ice making if the full ice state is reached.
Furthermore, the ice making process is divided into three ice content intervals according to the different ice content in the ice bucket of the ice making machine, and the actual volume of the liquid storage device is correspondingly adjusted to the three volume intervals according to the amount of the refrigerant needed by the cooling branch in the three ice content intervals. The three ice content intervals are three divisions according to the ice content in the ice bucket, which is an example and is not absolutely essential, for example, the three divisions can be divided into two divisions, four divisions, and the like.
Specifically, referring to fig. 5, when the obtained ice content in the ice bucket is less than or equal to 1/3 of the maximum volume of the ice bucket, the obtained ice content is a first ice content interval, and at this time, the actual volume of the liquid storage device is adjusted to the first volume interval, which is 1/3 of the maximum volume of the liquid storage device. And when the obtained ice content in the ice bucket is greater than 1/3 of the maximum volume of the ice bucket but less than or equal to 2/3 of the maximum volume of the ice bucket, the second ice content interval is set, and the actual volume of the liquid storage device is adjusted to the second volume interval and is 2/3 of the maximum volume of the liquid storage device. And when the obtained ice content in the ice bucket is greater than 2/3 of the maximum volume of the ice bucket, the third ice content interval is obtained, and the volume of the liquid storage device is adjusted to the third volume interval and is the maximum volume of the liquid storage device. In the embodiment, the quantitative adjustment scheme of the three modes divides the whole ice making process into three grades according to the ice content, so that the ice making control method of the whole refrigeration equipment is simplified and the production and use costs are reduced while the requirement that the refrigerant quantity is reduced in proportion to the increase of the ice content in the ice bucket is met.
At the beginning, whether ice making is started or not needs to be judged firstly; if the refrigeration device is started, judging the ice content in the ice bucket according to a weight sensor in the refrigeration device, and controlling the capacity of a liquid storage device 37 for storing a refrigerant according to the ice content so as to adjust the refrigerant amount in the second cooling branch; in this embodiment, the ice content in the ice bucket can be divided into three levels, and the volume of the liquid storage device 37 is also adjusted to three values, which are: when the obtained ice content in the ice bucket is less than or equal to 1/3 of the maximum volume of the ice bucket, the volume of the liquid storage device is adjusted to 1/3 of the maximum volume of the liquid storage device; when the ice content in the ice bucket is obtained and is larger than 1/3 of the maximum volume of the ice bucket but smaller than or equal to 2/3 of the maximum volume of the ice bucket, the volume of the liquid storage device is adjusted to be 2/3 of the maximum volume of the liquid storage device; when the obtained ice content in the ice bucket is larger than 2/3 of the maximum volume of the ice bucket, the volume of the liquid storage device is adjusted to the maximum volume of the liquid storage device. The above-mentioned action of judging ice content in the ice bucket is carried on in real time, can set up certain time interval to carry on periodically too; and the Hall sensor in the refrigeration equipment also judges whether the ice bucket is in a full ice state in real time, if not, the step S2 is controlled to be continuously carried out; and stopping ice making if the full ice state is reached.
In addition, the ice making control method of the refrigeration equipment can further comprise the step S4 of controlling the compressor to stop when the refrigeration equipment reaches the shutdown point. After the ice making is stopped and the interior of the storage room also reaches the preset temperature, the compressor can be turned off, and the energy consumption is saved.
Specifically, in step S4, the amount of refrigerant in the cooling branch is adjusted to speed up the refrigeration equipment reaching the shutdown point. After the ice making and refrigeration are completed, the actual volume of the liquid storage device 37 can be reduced to increase the amount of the refrigerant in the first cold supply branch and the second cold supply branch, the storage compartment is accelerated to reach the preset temperature, and the refrigeration equipment is accelerated to reach the shutdown point. After the ice making is stopped, the second cold supply branch only needs a small amount of refrigerant, so that the ice making outlet B1 can be closed by selectively utilizing the first control valve 35, the actual volume of the liquid storage device 37 is correspondingly adjusted according to the cold quantity required by the storage chamber reaching the preset temperature, the effect of the amount of the refrigerant in the first cold supply branch is achieved, the storage chamber reaching the preset temperature is accelerated, and the refrigeration equipment reaching the shutdown point is accelerated.
At the beginning, whether ice making is started or not needs to be judged; if the refrigeration equipment is started, judging the ice content in the ice bucket according to a weight sensor in the refrigeration equipment, and controlling the capacity of the liquid storage device 37 for storing the refrigerant according to the ice content so as to adjust the amount of the refrigerant in the second cooling branch; the above-mentioned action of judging ice content in the ice bucket is carried on in real time, can set up certain time interval to carry on periodically too; and the Hall sensor in the refrigeration equipment also judges whether the ice bucket is in a full ice state in real time, if not, the step of obtaining the ice content in the ice bucket in the step S2 is returned to and continuously carried out; if the ice-full state is reached, stopping ice making; judging whether the refrigeration equipment reaches a shutdown point in real time, if not, returning to the step of adjusting the quantity of the refrigerators in the cold supply branch in the step S2 for continuous operation, wherein the adjustment of the quantity of the refrigerators in the cold supply branch is realized by storing refrigerants with different volumes by the liquid storage device 37; and if the refrigeration equipment reaches the shutdown point, closing the compressor.
