Thus, the exemplary term "below" can encompass both a spatial orientation of below and above. As in the present utility model, for convenience of description, when the fresh-keeping box is used normally, the direction toward the ground is downward, the direction away from the ground is upward, the direction parallel to the ground is a horizontal direction, and the direction perpendicular to the ground is a vertical direction.

As shown in fig. 1, 2, 3 and 4, the present utility model provides a fresh box 10, the fresh box 10 including a cooling apparatus and a storage compartment 16. The storage chamber 16 is used for storing articles such as fresh food, and the cooling device is used for providing cooling capacity for the storage chamber 16 for storing articles, so that fresh food in the storage chamber 16 is subjected to pre-cooling treatment or cold insulation treatment.

The cooling device comprises an insulation box 11, a cooling module 12 and a ladder structure 13.

The cooling module 12 includes a cooling tank 121, a heat exchange unit 122, and a liquid supply unit 123.

The cold storage tank 121 has a cold storage chamber for receiving a solid and/or liquid cold storage medium. The heat exchange unit 122 has a heat exchange passage through which a liquid cold storage medium flows, and the heat exchange unit 122 is configured to supply cold to the storage chamber 16 in which the articles are stored. The liquid supply unit 123 communicates the cold storage chamber with the heat exchange passage so that the liquid cold storage medium in the cold storage chamber can enter the heat exchange passage.

The cold storage medium may store cold and exchange heat with air under the heat exchange action of the heat exchange unit 122 to supply the cold. The cold storage medium includes both single component cold storage media, such as water, alcohols, and the like; also included are multi-component cold storage media such as brine-based mixtures, alcohol-based mixtures, salt-alcohol-based mixtures. The proper cold storage medium can be selected according to the required cold quantity and the temperature control range thereof. The cold storage medium has a solid state and a liquid state. Solid-to-liquid stability, both morphological stability of physical storage and low entropy stability in energy, is not convenient for transport. The liquid cold storage medium is conveniently transferred to the heat exchange unit 122. The solid cold storage medium absorbs a large amount of heat when undergoing phase change to be liquid, namely releases a large amount of cold outwards.

The liquid supply unit 123 supplies the liquid cold storage medium in the cold storage tank 121 to the heat exchange unit 122, and the heat exchange unit 122 exchanges heat with air to discharge the cold of the cold storage medium.

The cold storage tank 121 is located in the heat insulation tank 11. The heat preservation box 11 is used for preventing the cooling capacity of the cooling medium in the cooling storage box 121 from being lost. The thermal insulation box 11 has a first opening 111.

As shown in fig. 7, the cold storage tank 121 has a second opening 1211 that communicates the cold storage chamber with the first opening 111. The step structure 13 is disposed below the first opening 111.

When it is necessary to add ice to the cold storage chamber in the cold storage box 121, the worker moves to a height corresponding to the first opening 111 through the stepped structure 13, and then loads the solid storage Leng Jiezhi into the cold storage chamber through the first opening 111 and the second opening 1211 outside the thermal insulation box 11 or into the thermal insulation box 11. The efficiency of the loading of the cold storage medium is improved because the articles in the storage chamber 16 do not need to be removed. The step structure 13 enables the first opening 111 to reach the height corresponding to the first opening 111 under the condition of higher height, so that the liquid storage Leng Jiezhi in the cold storage cavity is prevented from leaking out of the first opening 111 due to the fact that the first opening 111 is too low, and accordingly the cold storage medium can be conveniently filled into the cold storage box 121 by the staff under the condition that the capacity of the cold storage box 121 is ensured.

As shown in fig. 4, 5 and 6, the cooling module 12 further includes a ventilation chamber 124, an air inlet 125, an air outlet 126, a differential pressure fan 127 and an air supply fan 128.

A ventilation chamber 124 is formed in the heat-insulating case 11, and a heat exchange unit 122 is provided in the ventilation chamber 124. The air inlet 125 and the air outlet 126 both communicate the ventilation chamber 124 with the storage chamber 16 for storing articles. The differential pressure fan 127 and the supply fan 128 cooperate to cause air to flow between the plenum 124 and the storage compartment 16. Specifically, when the air in the ventilation chamber 124 flows through the heat exchange unit 122, the air absorbs the cold energy of the heat exchange unit 122, and then flows through the air outlet 126 to the storage chamber 16, so that the fresh air is pre-cooled or cold-preserved, and then the air in the storage chamber 16 returns to the ventilation chamber 124 through the air inlet 125, thereby completing the air circulation.

In the first embodiment of the present utility model, the differential pressure fan 127 is disposed at the air inlet 125, and the air supply fan 128 is disposed at the air outlet 126. In this embodiment, the differential pressure fan 127 creates a negative pressure in the storage compartment 16 near the air intake 125, forcing air from the storage compartment 16 into the ventilation compartment 124. The blower 128 blows air from the plenum 124 toward the storage compartment 16. Not shown in the drawings of this embodiment.

In the second embodiment of the present utility model, the ventilation chamber 124 includes a pressure relief cavity 1241, where the pressure relief cavity 1241 corresponds to the position of the air inlet 125; the differential pressure fan 127 is disposed at one side of the pressure relief cavity 1241 near the air outlet 126, and the air supply fan 128 is disposed at the air outlet 126. In this embodiment, the differential pressure fan 127 creates a negative pressure within the relief cavity 1241, forcing air from the storage chamber 16 into the ventilation chamber 124. The blower 128 blows air from the plenum 124 toward the storage compartment 16. The differential pressure fan 127 is horizontally arranged, and the side of the differential pressure fan 127 facing the pressure relief cavity 1241 is an air suction side.

Preferably, the differential pressure fan 127 is a centrifugal fan to ensure that a negative pressure is created within the storage chamber 16 or the relief cavity 1241. The air supply fan 128 is an axial flow fan, and improves the air supply effect.

As shown in fig. 4, 5 and 7, the cold storage tank 121 is disposed in the ventilation chamber 124, a recess 1212 recessed toward the first opening 111 is provided on a side of the cold storage tank 121 facing away from the first opening 111, and a wall of the recess 1212 is used to constitute a wall of the pressure relief chamber 1241.

As shown in fig. 7, further, the top of the cold storage tank 121 has an opening constituting a second opening 1211, and the first opening 111 is provided at the front side of the heat insulation tank 11. After the worker passes through the first opening 111 and enters the heat insulation box 11, the worker can directly stand in the cold storage box 121 because the second opening 1211 is arranged at the top of the cold storage box 121, so that the worker can conveniently transport the solid cold storage medium into the cold storage box 121.

The front wall of the cold storage tank 121 has a recess 1213 recessed downward from the top of the front wall of the cold storage tank 121 at a position corresponding to the first opening 111, the first opening 111 corresponds to the position of the recess 1213 in the front-rear direction, the top of the first opening 111 is higher than Chu Lengxiang 121, and the bottom of the first opening 111 is not higher than the bottom wall of the recess 1213. By making the bottom of the first opening 111 lower than the top of the cold storage tank 121, the length of the first opening 111 in the longitudinal direction is increased, so that a worker can conveniently pass through the first opening 111 to enter the heat insulation tank 11, and a worker can conveniently transport a large solid storage Leng Jiezhi into the heat insulation tank 11 through the first opening 111, and a groove 1213 corresponding to the position of the first opening 111 is formed in the cold storage tank 121 to avoid the cold storage tank 121 from obstructing the entry of the worker or the transportation of the solid storage medium. In addition, since the solid cold storage medium carried into the cold storage tank 121 may be higher than the bottom wall of the groove 1213, the liquefied liquid storage Leng Jiezhi fills the gap between the solid cold storage mediums, and the height of the gap is lower than the bottom wall of the groove 1213, so that the capacity of the cold storage tank 121 is not affected by the arrangement of the groove 1213.

As shown in fig. 1 and 3, in an embodiment of the present utility model, the cooling device further includes a cover 15 for opening or closing the first opening 111. The cover 15 is detachably or rotatably mounted to the thermal insulation case 11, and a worker opens or closes the first opening 111 by detaching or rotating the cover 15. Since the cover 15 needs to be frequently opened, the cover 15 is preferably rotatably connected to the insulation box 11.

As shown in fig. 4 and 6, in an embodiment of the present utility model, the liquid supply unit 123 includes a liquid supply pipe 1231 that communicates the cold storage tank 121 with the heat exchange unit 122, and a liquid supply pump 1232 for driving the liquid cold storage medium in the cold storage tank 121 to flow through the liquid supply pipe 1231 and then be delivered to the heat exchange channel. Both the liquid supply pipe 1231 and the liquid supply pump 1232 are disposed in the ventilation chamber 124. The inlet of the heat exchange channel is connected with the liquid supply pipe 1231, and the outlet of the heat exchange channel is connected with at least one pipeline (not shown) extending into the cold storage cavity, so that the liquid cold storage medium after heat exchange in the heat exchange unit 122 can return to the cold storage tank 121, exchange heat with the solid cold storage medium in the cold storage tank 121 and return to the heat exchange unit 122 again through the liquid supply unit 123.

As shown in fig. 1, 2, 3, 4 and 5, the cooling device further comprises a power supply module 14. The power supply module 14 is configured to supply power to the liquid supply pump 1232. Further, the power supply module 14 is further configured to supply power to the differential pressure fan 127 and the air supply fan 128.

The power supply module 14 is located outside the insulation box 11, and the top of the power supply module 14 forms the step structure 13.
