Detailed Description

In order that the above objects, features and advantages of embodiments according to the present application may be more clearly understood, embodiments according to the present application will be described in further detail below with reference to the accompanying drawings and detailed description. It should be noted that the features of the embodiments according to the present application may be combined with each other without conflict.

In the following description, numerous specific details are set forth to provide a thorough understanding of embodiments according to the present application, however, embodiments according to the present application may be practiced in other ways than those described herein, and therefore the scope of protection afforded by embodiments according to the present application is not limited by the specific embodiments disclosed below.

Some embodiments according to the present application are described below with reference to fig. 1-12.

Example 1

As shown in fig. 1, a refrigeration system 100 is proposed according to an embodiment of the first aspect of the present application. The refrigeration system 100 includes a storage compartment 101, a refrigeration compartment 106, and an air storage compartment 104.

Specifically, the storage chamber 101 and the air receiver 104 are both in communication with the refrigeration chamber 106. An evaporator 108, a defrosting device 110 and a fan 112 are arranged in the refrigerating chamber 106. The cooling chamber 106 and the storage chamber 101 are connected to each other through an air duct 102, and are communicated with each other through the air duct 102. The fan 112 is used to drive the air in the refrigeration chamber 106 to flow to the storage chamber 101 through the air duct 102 or directly to the air storage chamber 104.

The evaporator 108 is used for exchanging heat with the air in the refrigeration chamber 106 for refrigeration, and drives cold air to flow to the storage chamber 101 through the air duct 102 by the fan 112, so as to ensure a low-temperature environment in the storage chamber 101, and achieve the purpose of food material preservation. Of course, the cool air may also partially flow to the air receiver 104 to exchange heat with the hot air in the air receiver 104, thereby reducing the temperature thereof.

The evaporator 108 absorbs heat for a long time to cool, the surface of the evaporator may frost, and the frost layer may affect the air flow near the evaporator 108, thereby reducing the cooling effect of the evaporator 108. The defrosting device 110 is arranged to defrost the evaporator 108. The frost layer is melted by heating the evaporator 108 by the defrosting apparatus 110. The hot air generated by heating the frost layer can enter the air receiver 104 to be stored under the driving of the fan 112, and is slowly cooled under the ambient temperature and the refrigeration effect of the evaporator 108. The setting of gas receiver 104, to at least part of steam storage, the separation just also can not lead to steam to storeroom 101 direct heating outside storeroom 101, when changing the frost, is favorable to slowing down storeroom 101's programming rate, reduces the possibility of storeroom 101 intensification to ensure the fresh-keeping environment and the fresh-keeping effect of eating the material. It will be appreciated that some of the hot air may be driven by the fan 112 to the air duct 102 and thus enter the storage compartment 101 through the air duct 102, but due to the arrangement of the air reservoir 104, the hot air entering the storage compartment 101 is greatly reduced, and therefore the temperature of the storage compartment 101 is greatly affected by the hot air.

In some related arts, the hot gas generated by defrosting is directly discharged to the outside of the refrigeration apparatus 10, which makes it difficult to seal the refrigeration apparatus 10, and is not favorable for maintaining a low-temperature environment inside the refrigeration apparatus 10. And the technical scheme of this application has set up the gas receiver 104 and has kept apart the steam, does not have the intercommunication with external environment to be favorable to guaranteeing the inside heat preservation effect of refrigeration plant 10, be convenient for refrigeration plant 10 especially the inside low temperature environment that keeps of storeroom 101.

When the evaporator 108 is cooling, the cooling compartment 106 is in a cooling state. The cold air after heat exchange and refrigeration is driven by the fan 112 and flows to the storage chamber 101 through the air duct 102, so that the low-temperature environment in the storage chamber 101 is ensured, and the aim of preserving food materials is fulfilled. Of course, the cool air may also partially flow to the air receiver 104 to exchange heat with the hot air in the air receiver 104, thereby reducing the temperature thereof. In the cooling state, the first damper 120 is opened to ensure that the cool air can enter the wind tunnel 102 to flow toward the storage chamber 101.

The evaporator 108 absorbs heat for a long time to cool, the surface of the evaporator may frost, and the frost layer may affect the air flow near the evaporator 108, thereby reducing the cooling effect of the evaporator 108. The defrosting device 110 is provided to defrost the evaporator 108. When the defrosting device 110 defrosts the evaporator 108, the cooling compartment 106 is in a defrosting state. The frost layer is melted by heating the evaporator 108 by the defrosting apparatus 110. The hot air generated by heating the frost layer can enter the air storage chamber 104 to be stored under the driving of the fan 112, and is slowly cooled under the cooling effect of the evaporator 108 and the ambient temperature.

In the defrosting state of the refrigerating compartment 106, the first damper 120 is closed to close the air duct 102, and the hot air is blocked from flowing to the storage compartment 101. The hot gas can only flow to the air reservoir 104 under the drive of the fan 112. At this point, the reservoir 104 may store all of the hot gas. Through the cooperation of first air door 120 and gas receiver 104 for steam no longer flows to wind channel 102 and gets into storeroom 101, has avoided steam to storeroom 101 direct heating completely, has further reduced the influence of steam to storeroom 101 temperature, thereby is favorable to further guaranteeing the fresh-keeping effect of eating the material.

An evaporator 108, a defrosting device 110 and a fan 112 are arranged in the refrigerating chamber 106. An air duct 102 is connected between the refrigerating chamber 106 and the storage chamber 101, and is communicated through the air duct 102. A first damper 120 is disposed on the air duct 102. A second damper 122 is provided between the air storage chamber 104 and the refrigeration chamber 106. The fan 112 is used to drive the air in the refrigeration chamber 106 to flow to the storage chamber 101 through the air duct 102 or directly to the air storage chamber 104.

The refrigeration compartment 106 has a refrigerated state and a defrost state. The evaporator 108 is used for heat exchange refrigeration with the gas in the refrigeration compartment 106. When the evaporator 108 is cooling, the cooling compartment 106 is in a cooling state. The cold air after heat exchange and refrigeration is driven by the fan 112 and flows to the storage chamber 101 through the air duct 102, so that the low-temperature environment in the storage chamber 101 is ensured, and the aim of preserving food materials is fulfilled. Of course, the cool air may also partially flow to the air receiver 104 to exchange heat with the hot air in the air receiver 104, thereby reducing the temperature thereof. In the cooling state, the first damper 120 is opened to ensure that the cool air can enter the duct 102 to flow toward the storage chamber 101. Meanwhile, the second damper 122 is closed, so that the cold air is driven by the fan 112 to flow to the air duct 102 completely, thereby preventing part of the cold air from flowing to the air storage chamber 104 and causing cold loss.

The evaporator 108 absorbs heat for a long time to cool, the surface of the evaporator may frost, and the frost layer may affect the air flow near the evaporator 108, thereby reducing the cooling effect of the evaporator 108. The defrosting device 110 is arranged to defrost the evaporator 108. When the defrosting device 110 defrosts the evaporator 108, the cooling compartment 106 is in a defrosting state. The frost layer is melted by heating the evaporator 108 by the defrosting apparatus 110. The hot air generated by heating the frost layer can enter the air storage chamber 104 to be stored under the driving of the fan 112, and is slowly cooled under the cooling effect of the evaporator 108 and the ambient temperature.

In the defrosting state of the refrigerating compartment 106, the first damper 120 is closed to close the air duct 102 and block the hot air from flowing to the storage compartment 101. At the same time, the second damper 122 is opened, and the hot air flows to the air receiver 104 completely under the driving of the blower 112. And stored within the air reservoir 104. Through the cooperation of first air door 120, second air door 122 and reservoir 104 for steam no longer flows to wind channel 102 and all gets into storeroom 101, has avoided steam to storeroom 101's direct heating completely, has further reduced the influence of steam to storeroom 101 temperature, thereby is favorable to further guaranteeing the fresh-keeping effect of eating the material.

In addition, in a refrigerating state, the second door body is closed, hot air is blocked in the air storage chamber 104, interference of the hot air on refrigeration is avoided, and therefore the influence of the hot air on refrigeration of the evaporator 108 is reduced. This is advantageous in improving the efficiency of cooling the storage chamber 101.

It should be noted that the air receiver 104 is a semi-enclosed structure that is in communication with the refrigeration compartment 106 only, and thus the entire refrigeration system 100 remains an enclosed structure that is not in communication with the outside environment. In some related arts, the hot gas generated by defrosting is directly discharged to the outside of the refrigeration apparatus 10, which makes it difficult to seal the refrigeration apparatus 10, and is not favorable for maintaining a low-temperature environment inside the refrigeration apparatus 10. And the technical scheme of this application has set up the gas receiver 104 and has kept apart the steam, does not have the intercommunication with external environment to be favorable to guaranteeing the inside heat preservation effect of refrigeration plant 10, be convenient for refrigeration plant 10 especially the inside low temperature environment that keeps of storeroom 101.

As shown in fig. 3, an insulating layer 114 is further provided between the refrigeration compartment 106 and the air storage compartment 104.

Through the setting of heat preservation 114, after hot gas gets into the air receiver 104, close second air door 122, be favorable to the heat in the better separation air receiver 104 and the heat exchange in the refrigeration chamber 106 to reduce the temperature variation speed in the air receiver 104, just also can further reduce the influence of hot gas to storeroom 101, to refrigeration chamber 106 cold air. It can be understood that the heat insulating performance of the heat insulating layer 114 makes the heat exchange between the hot air inside and outside the second air door 122 and the cold air difficult, which is beneficial to ensure that the air in the storage chamber 101 and the refrigeration chamber 106 is maintained in a lower temperature range.

Example 4

According to yet another embodiment of the first aspect of the present application, a refrigeration system 100 is presented. The refrigeration system 100 includes a storage compartment 101, a refrigeration compartment 106, an air reservoir 104, a first damper 120, a second damper 122, and a controller.

Specifically, the storage chamber 101 and the air receiver 104 are both in communication with the refrigeration chamber 106. An evaporator 108, a defrosting device 110 and a fan 112 are arranged in the refrigerating chamber 106. An air duct 102 is connected between the refrigerating chamber 106 and the storage chamber 101, and is communicated through the air duct 102. A first damper 120 is disposed on the air duct 102. A second damper 122 is provided between the air storage compartment 104 and the refrigeration compartment 106. The fan 112 is used to drive the air in the refrigeration chamber 106 to flow to the storage chamber 101 through the air duct 102 or directly to the air storage chamber 104.

The refrigeration compartment 106 has a refrigerated state and a defrost state. In the cooling state, the evaporator 108 is used for heat exchange cooling with the gas in the cooling chamber 106. In the defrosting state, the defrosting device 110 heats the evaporator 108, defrosts the evaporator 108, and generates hot air.

When the evaporator 108 is used for refrigerating, cold air subjected to heat exchange and refrigeration is driven by the fan 112 and flows to the storage chamber 101 through the air duct 102, so that a low-temperature environment in the storage chamber 101 is ensured, and the aim of keeping food fresh is fulfilled. Of course, the cool air may also partially flow into the air receiver 104 to exchange heat with the hot air in the air receiver 104, thereby reducing the temperature thereof. In the cooling state, the first damper 120 is opened to ensure that the cool air can enter the duct 102 to flow toward the storage chamber 101. Meanwhile, the second damper 122 is closed, so that the cold air is driven by the fan 112 to flow to the air duct 102 completely, thereby preventing part of the cold air from flowing to the air storage chamber 104 and causing cold loss.

The evaporator 108 absorbs heat for a long time to cool, the surface of the evaporator may frost, and the frost layer may affect the air flow near the evaporator 108, thereby reducing the cooling effect of the evaporator 108. The defrosting device 110 is arranged to defrost the evaporator 108. When the defrosting device 110 defrosts the evaporator 108, the cooling compartment 106 is in a defrosting state.

The hot air generated by heating the frost layer can enter the air storage chamber 104 to be stored under the driving of the fan 112, and is slowly cooled under the cooling effect of the evaporator 108 and the ambient temperature.

In the defrosting state of the refrigerating compartment 106, the first damper 120 is closed to close the air duct 102, and the hot air is blocked from flowing to the storage compartment 101. At the same time, the second damper 122 is opened, and the hot air flows to the air receiver 104 completely under the driving of the blower 112. And stored within the air reservoir 104. Through the cooperation of first air door 120, second air door 122 and gas receiver 104 for steam no longer flows to wind channel 102 and all gets into storeroom 101, has avoided steam to storeroom 101's direct heating completely, has further reduced the influence of steam to storeroom 101 temperature, thereby is favorable to further guaranteeing the fresh-keeping effect of edible material.

In addition, in the refrigeration state, the second door body is closed, so that hot gas is blocked in the air storage chamber 104, the interference of the hot gas on refrigeration is avoided, and the influence of the hot gas on the refrigeration of the evaporator 108 is reduced. This is advantageous in improving the efficiency of cooling the storage chamber 101.

Further, in the present embodiment, the controller is electrically connected to the defrosting device 110. At the same time, the controller is also electrically connected to the first damper 120 and the second damper 122, respectively. Through the electrical connection with the defrosting device 110, the controller can acquire the operation state of the defrosting device 110. By obtaining the operation state of the defrosting device 110, it can be determined whether hot gas is generated in the refrigerating compartment 106. When the defrosting device 110 operates to defrost the evaporator 108, hot gas is generated. At this time, the controller controls the first damper 120 to close, so as to prevent the hot air from flowing to the storage chamber 101 through the air duct 102 and affecting the food fresh-keeping effect. Meanwhile, the controller also controls the second damper 122 to open, and opens the air reservoir 104, so that the hot air flows to the air reservoir 104 to be stored under the driving of the fan 112. After the defrosting device 110 stops operating, hot air is not generated any more. The controller controls the second air door 122 to be closed after determining that the hot air is not generated any more by acquiring the operating state of the defrosting device 110, so that the hot air is completely sealed in the air storage chamber 104, and is slowly cooled under the action of the internal environment temperature of the refrigerating system 100, thereby reducing and basically avoiding the temperature influence on the storage chamber 101. Meanwhile, the first damper 120 is opened so that the cold air cooled by the heat exchange of the evaporator 108 can flow toward the storage chamber 101 through the air duct 102.

In addition, the controller controls the opening and closing of the two air doors according to the operation state of the defrosting device 110, which is beneficial to ensuring the opening and closing timeliness of the two air doors and further reducing the possibility that hot air enters the storage chamber 101 through the air duct 102.

Example 5

As shown in fig. 4, a refrigeration system 100 is proposed according to yet another embodiment of the first aspect of the present application. The refrigeration system 100 includes a storage compartment 101, a refrigeration compartment 106, an air storage compartment 104, a temperature sensor 116, a first damper 120, a second damper 122, and a controller.

Specifically, the storage chamber 101 and the air receiver 104 are both in communication with the refrigeration chamber 106. An evaporator 108, a defrosting device 110 and a fan 112 are arranged in the refrigerating chamber 106. An air duct 102 is connected between the refrigerating chamber 106 and the storage chamber 101, and is communicated through the air duct 102. A first damper 120 is disposed on the air duct 102. A second damper 122 is provided between the air storage chamber 104 and the refrigeration chamber 106. The fan 112 is used to drive the air in the refrigeration chamber 106 to flow to the storage chamber 101 through the air duct 102 or directly to the air storage chamber 104.

When the evaporator 108 is used for refrigerating, cold air subjected to heat exchange and refrigeration is driven by the fan 112 and flows to the storage chamber 101 through the air duct 102, so that a low-temperature environment in the storage chamber 101 is ensured, and the aim of keeping food fresh is fulfilled. Of course, the cool air may also partially flow to the air receiver 104 to exchange heat with the hot air in the air receiver 104, thereby reducing the temperature thereof. In the cooling state, the first damper 120 is opened to ensure that the cool air can enter the duct 102 to flow toward the storage chamber 101. Meanwhile, the second damper 122 is closed, so that the cold air is driven by the fan 112 to flow to the air duct 102 completely, thereby preventing part of the cold air from flowing to the air storage chamber 104 and causing cold loss.

Further, in the present embodiment, a temperature sensor 116 is provided in the cooling chamber 106. The temperature sensor 116 is connected to the controller. A temperature sensor 116 is disposed within the refrigeration compartment 106 to facilitate sensing of the temperature of the refrigeration compartment 106 to determine the status of the refrigeration compartment 106. Specifically, a preset value may be set, and when the detected temperature is less than the preset value, it is determined that the refrigeration chamber 106 is in the refrigeration state, and when the detected temperature is greater than or equal to the preset value, it is determined that the refrigeration chamber 106 is in the defrosting state. The controller is electrically connected to the temperature sensor 116. At the same time, the controller is also electrically connected to the first damper 120 and the second damper 122, respectively. Through the electrical connection with the temperature sensor 116, the controller can determine the status of the refrigeration compartment 106 by the temperature of the compartment 106, and thus determine whether hot gas is generated in the compartment 106. When the detected temperature is greater than or equal to the preset value, the refrigerating chamber 106 is in a defrosting state, and the controller controls the first air door 120 to be closed, so that the fresh-keeping effect of food materials is prevented from being influenced by hot air flowing to the storage chamber 101 through the air duct 102. Meanwhile, the controller also controls the second damper 122 to open, and opens the air reservoir 104, so that the hot air flows to the air reservoir 104 to be stored under the driving of the fan 112. When the detected temperature is lower than the preset value, the refrigeration chamber 106 is in a refrigeration state, and the controller controls the second damper 122 to close, so that the hot air is completely sealed in the air storage chamber 104, and the temperature is slowly reduced under the action of the internal environment temperature of the refrigeration system 100, thereby reducing and basically avoiding the temperature influence on the storage chamber 101. Meanwhile, the first damper 120 is opened so that the cold air cooled by the heat exchange of the evaporator 108 can flow toward the storage chamber 101 through the air duct 102.
