Detailed Description
The present invention will be described in detail below with reference to specific embodiments shown in the drawings. These embodiments are not intended to limit the present invention, and structural, methodological, or functional changes made by those skilled in the art according to these embodiments are included in the scope of the present invention.
In the various drawings of the present invention, certain dimensions of structures or portions are exaggerated relative to other structures or portions for ease of illustration and, therefore, are used only to illustrate the basic structure of the subject matter of the present invention.
The invention provides a storage device 10 which comprises a storage container 11.
The storage container 11 has a loading chamber 111 and a cooling chamber 112 provided adjacent to the loading chamber 111. The load chamber 111 is used for placing the articles to be cooled, and the cooling chamber 112 is used for receiving coolant to provide the cooling energy for cooling the articles.
The wall of the cooling chamber 112 adjacent to the loading chamber 111 is elastically arranged, so that the wall can be extended and contracted to enable the cooling chamber 112 to have a first contracted state and a second expanded state.
The walls of the cooling chamber 112 are provided with ports for charging and discharging the coolant, and the cooling chamber 112 assumes the second state when the coolant is charged and assumes the first state when the coolant is discharged. The coolant can be selected from liquids having a freezing point below-40 ℃ and a boiling point above 80 ℃, such as brine, glycol, antifreeze.
When the storage device 10 does not need to store, the coolant in the cooling chamber 112 is discharged. When the articles need to be rapidly refrigerated, when the cooling cavity 112 is in the first state of contraction, the articles are placed into the carrying cavity 111, then the secondary refrigerant is filled into the cooling cavity 112 to enable the cooling cavity 112 to be in the second state of expansion, the wall part of the cooling cavity 112 is in contact with the articles in the carrying cavity 111, and the secondary refrigerant exchanges heat with the articles through the wall part of the cooling cavity 112 adjacent to the carrying cavity 111 to realize rapid cooling.
The wall portion that elasticity set up can laminate the surface of article, makes area of contact increase to promote heat exchange efficiency, accelerate the cooling rate. Meanwhile, the wall part can prevent the secondary refrigerant from contacting with the articles, and the influence of slight corrosivity or slight toxicity of the secondary refrigerant on the eating safety of the articles is avoided.
Specifically, the cooling chamber 112 surrounds the object carrying chamber 111 to increase the contact area between the wall of the cooling chamber 112 and the object carrying chamber 111, thereby improving the cooling effect.
The wall of the cooling chamber 112 adjacent to the loading chamber 111 is an elastic membrane 113. When the cooling cavity 112 is in the first state, the elastic membrane 113 is attached to the inner wall of the storage container 11, and when the cooling cavity 112 is in the second state, the elastic membrane 113 expands and swells under the action of the coolant.
The end of the elastic membrane 113 is connected with the inner wall of the storage container 11 in a sealing way, and the cooling cavity 112 is arranged between the cooling membrane and the inner wall of the storage container 11, namely, one wall part of the cooling cavity 112 is the inner wall of the storage container 11, and the other wall part is the elastic membrane 113.
In one embodiment of the present invention, the top end and the bottom end of the elastic membrane 113 are connected to the sidewall of the storage container 11.
In another embodiment of the present invention, only the top end of the elastic membrane 113 is connected to the sidewall of the storage container 11, and the elastic membrane 113 includes a first portion corresponding to the sidewall of the storage container 11 and a second portion corresponding to the sidewall of the storage container 11. When the article is placed in the loading cavity 111 and the cooling cavity 112 is in the second state, the weight of the article presses the portion of the elastic film 113 covering the bottom wall of the storage container 11, the elastic film 113 does not jack up the article, and a small amount of coolant between the bottom wall of the storage container 11 and the elastic film 113 can cool the bottom of the article, so that the cooling effect is further improved, and the cooling speed is increased.
The interface for charging or discharging the secondary refrigerant is provided on the storage container 11 to prevent the interface from affecting the surface of the cooling film attached to the article.
Further, the storage device 10 further includes a cooling system. The cooling system, which provides the cooling necessary for cooling the articles, has a coolant and a drive mechanism 12 for driving the coolant into and out of the cooling chamber 112.
The driving mechanism 12 includes a coolant storage container 121, an inlet pipe 122 and an outlet pipe 123 for communicating the coolant storage container 121 with the cooling chamber 112, and a circulation pump 124 connected to the inlet pipe 122 or the outlet pipe 123.
The coolant storage container 121 is a space for storing coolant. The coolant circulates in a coolant circulation path, which is defined by a coolant storage container 121, a liquid inlet pipe 122, a cooling chamber 112, and a liquid outlet pipe 123, and finally returns to the coolant storage container 121. The circulation pump 124 provides power for the coolant circulation. When the coolant circulates, the cooling chamber 112 remains in the second state and the circulating coolant ensures that the temperature of the cooling chamber 112 does not fluctuate and can remain at a lower cooling temperature.
Specifically, an inlet valve 125 is installed at an end of the inlet pipe 122 away from the coolant storage container 121, and an outlet valve 126 is installed at an end of the outlet pipe 123 away from the coolant storage container 121. The wall of cold supply chamber 112 far from loading chamber 111 is provided with a first quick connector connected to liquid inlet valve 125 and a second quick connector connected to liquid outlet valve 126.
The first quick-connect connector and the second quick-connect connector are mounted on the interface of the cold supply cavity 112, that is, on the side wall of the storage container 11, so as to prevent the liquid inlet pipe 122 and the liquid outlet pipe 123 from obstructing the elastic membrane 113 from adhering to the surface of the object. By providing the first quick-connect connector and the second quick-connect connector, the liquid inlet pipe 122 and the liquid outlet pipe 123 can be selectively connected to the storage container 11. When the storage container 11 needs to be moved, the liquid inlet valve 125 and the liquid outlet valve 126 are separated from the first quick-connection-peg and the second quick-connection-peg respectively. Therefore, when the storage container 11 moves, the liquid inlet pipeline 122 and the liquid outlet pipeline 123 do not interfere with the moving process of the storage container 11.
The secondary refrigerant storage container 121 may be disposed above the storage container 11 or below the storage container 11. In one embodiment of the present invention, the secondary refrigerant storage container 121 is preferably disposed below the storage container 11.
Specifically, the coolant storage container 121 is located below the storage container 11, the circulation pump 124 is connected to the liquid inlet pipe 122, the circulation pump 124 transports the coolant into the cooling cavity 112, and the coolant in the cooling cavity 112 returns to the coolant storage container 121 under the action of gravity.
The inlet valve 125 is disposed above the outlet valve 126 to prevent the coolant in the cooling chamber 112 from being completely returned to the coolant storage container 121.
Further, the storage device 10 further includes a refrigeration system 13. The refrigeration system 13 functions to refrigerate the coolant in the coolant storage container 121.
The refrigeration system 13 comprises a compressor 131, a condenser 132, a throttling device 133 and an evaporation device 134 connected by means of pipes forming a circuit. A circulating refrigerant flows among the compressor 131, the condenser 132, the expansion device 133, and the evaporation device 134.
When the refrigeration system 13 operates, the refrigerant is compressed into a high-temperature and high-pressure gas by the compressor 131, and then enters the condenser 132 to exchange heat to form a medium-temperature and high-pressure liquid refrigerant. The liquid refrigerant passes through the throttling device 133, is throttled and depressurized, then enters the evaporation device 134 to be subjected to heat exchange and gasification, and finally the gaseous refrigerant returns to the compressor 131 to complete the refrigeration cycle. The throttling device 133 is a capillary tube or an expansion valve. During operation of the refrigeration system 13, the evaporator 134 provides refrigeration to the coolant in the coolant storage container 121.
The evaporation device 134 may be attached to the coolant storage container 121 or may be provided in the coolant storage container 121.
The invention also provides refrigeration equipment which comprises a box body 20 formed with the storage compartment 21, a door body 23 for opening or closing the box body 20 and the storage device 10. The storage container 11 of the storage device 10 is disposed in the storage compartment 21, and the refrigeration system 13 and the cooling system 12 are disposed in the cabinet 20.
Specifically, a press cabin 22 is provided inside the case 20. The cabinet 20 includes a cabinet case and a foaming layer provided inside the cabinet case. The compressor 131 is placed in the press chamber 22 and the condenser 132 is placed between the box shell and the foam layer or in the press chamber 22. The throttle device 133 pipe is disposed between the evaporation device 134 and the condenser 132.
A press machine room 22 is provided at the rear of the case 20, and a secondary refrigerant storage container 121 is adjacent to the press machine room 22. Since the rear side is not used for placing articles, the space utilization can be improved by disposing the pressing compartment 22 and the secondary refrigerant storage container 121 at the rear of the cabinet 20.
The storage container 11 is slidably disposed in the storage compartment 21 in the front-rear direction, and the top of the loading cavity 111 is open. When articles need to be placed, the user opens the door at the front side of the box body 20, separates the liquid inlet valve 125 and the liquid outlet valve 126 from the first quick-connection-peg and the second quick-connection-peg respectively, and then pulls the storage container 11 to place the articles.
The evaporator 134 includes a first evaporator 1341 and a second evaporator 1342 connected in series, the first evaporator 1341 is disposed in the coolant storage container 121, and the second evaporator 1342 is disposed outside the coolant storage container 121 to cool the storage compartment 21.
The first evaporator 1341 is used to cool the coolant in the coolant storage container 121, and the second evaporator 1342 is used to cool the interior of the storage compartment 21 so as to maintain a low temperature in the interior of the storage compartment 21. Therefore, the refrigeration equipment of the invention has the function of normal refrigeration besides the function of rapid refrigeration. When the articles in the loading cavity 111 are cooled to a low temperature, the circulation pump 124 stops operating, and the temperature inside the storage compartment 21 is reduced by the cold energy emitted from the second evaporator 1342 to maintain the temperature of the articles, thereby preventing the articles from being heated rapidly.
In one embodiment of the present invention, the second evaporator 1342 is installed on the inner wall of the storage compartment 21 to directly supply cold to the storage compartment 21.
In another embodiment of the present invention, a cavity for accommodating the second evaporator 1342 is provided inside the box 20, and the cooling capacity of the second evaporator 1342 is transferred into the storage compartment 21 by a fan. The coolant storage container 121 is also located in this cavity.
The first evaporator 1341 is connected to the throttling device 133, and the second evaporator 1342 is connected to the compressor 131, so as to ensure that the temperature of the refrigerant entering the first evaporator 1341 is low, thereby ensuring that the refrigeration equipment has a good rapid cooling function. The cold energy emitted by the second evaporator 1342 only needs to prevent the temperature in the storage compartment 21 from being too high, and the temperature of the refrigerant entering the second evaporator 1342 does not need to be very low, so the second evaporator 1342 is disposed at the rear end of the first evaporator 1341.
The second evaporator 1342 is attached to the coolant storage container 121, and the cold energy emitted from the second evaporator 1342 is used to maintain the low temperature inside the storage compartment 21, and further cool the coolant storage container 121, thereby preventing the cold energy from being emitted from the coolant storage container 121.
The storage compartments 21 are provided with a plurality of storage containers 11, and the storage containers are longitudinally distributed. A plurality of branch pipelines are arranged on the liquid inlet pipeline 122 and the liquid outlet pipeline 123 for connecting different storage containers 11, and a circulating pump 124 is arranged on each branch pipeline of the liquid inlet pipeline 122.
The above-listed detailed description is only a specific description of a possible embodiment of the present invention, and they are not intended to limit the scope of the present invention, and equivalent embodiments or modifications made without departing from the technical spirit of the present invention should be included in the scope of the present invention.
