Description

Mobile multifunctional fresh-keeping box, refrigerator including the fresh-keeping box, and food fresh-keeping method

technical field

The invention belongs to the technical field of household appliances, and in particular relates to a mobile multifunctional fresh-keeping box, a refrigerator containing the fresh-keeping box, and a food fresh-keeping method.

Background technique

With the improvement of people's living standards, the demand for freshness of refrigerators in the market is getting higher and higher; at the same time, with the changes in people's lifestyles, there are mobile refrigeration needs. This kind of demand does not require a large volume and a long refrigeration time, but requires portability and convenience, as well as a better fresh-keeping effect. There are special small devices for temporarily storing milk on the market, but considering that they need to be purchased separately, and their use cycle is limited to breastfeeding mothers, it increases the cost of living. At present, the popularity rate of refrigerators is very high. If ordinary refrigerators are used to realize this function through function expansion, the cost of living will be reduced while increasing the utilization rate of refrigerators.

At present, the fresh-keeping methods of refrigerators include photosynthetic fresh-keeping, natural fresh-keeping, humidification fresh-keeping, zero-degree fresh-keeping, vacuum fresh-keeping, VC fresh-keeping, etc., but these fresh-keeping methods rely on the refrigerator system and cannot realize the mobile fresh-keeping function. Regarding the mobile refrigeration method, the patent "Multifunctional Refrigerator Cooler (CN200820157138.2)" provides a short-term cooling technology using the cold storage device, but this technology is only realized by using the cold storage plate, which is inconvenient to move and store, and is only suitable for indoors It is used for a very short time, which cannot meet the requirements of long-term outdoor use, and has no fresh-keeping function. The patent "Mobile cold storage device (CN03269594.2)" uses a hollow cold storage device to realize the mobile refrigeration function. It is characterized in that the cold storage device is a hollow concave body with an upper opening. , and then put in cold drinks or medicines, and use the cooling effect of the cold storage to keep the low temperature, so as to avoid the energy loss of the refrigerator caused by repeated taking out or putting in cold drinks and medicines. This patent occupies the effective volume of the refrigerator during the cooling process of the cold accumulator, which reduces the efficiency of the refrigerator; due to the opening of the upper part of the cold accumulator, the heat exchange with the external environment is fast, and the cooling capacity of the cold accumulator is lost quickly, so it is not suitable for carrying and outdoor use, especially in the outside world. When the ambient temperature is high (such as summer). Simultaneously, this patent has only refrigeration function, does not have fresh-keeping function. In addition, the cold accumulator in this patent has a single function, and because it is an integral structure, the maintenance cost is high and the material utilization efficiency is low.

In view of the above problems, it is necessary to propose a device that can realize functions such as convenient storage, movement, and freshness preservation, while avoiding excessive occupation of the effective volume of the refrigerator, so as to improve the use efficiency of the refrigerator and reduce the loss of cooling capacity in the device when moving. The preservation time is longer. In addition, the function of the cold accumulator in the device can be effectively expanded, and its utilization efficiency is improved to the greatest extent.

The number of hooks can be multiple, and the positions can be determined according to specific needs, which is not limited here. In addition, the connection mode between the box cover and the box body may be hinged connection other than snap connection, depending on the specific circumstances.

When it is necessary to use a mobile fresh-keeping box, first place the EPS insulation board 104 around the inside of the box body 101, and then assemble each sheet-shaped body into the box body in turn, and snap and match between each boss 106 and the groove 107, and place the A plurality of sheets are effectively connected and assembled to form a cold accumulator, and at the same time ensure that the EPS insulation board can be located in the limiting groove 105, and effectively limit and fix the cold accumulator through the limiting rib 108, and then insert the sealing strip into the groove at the upper end of the box body In the groove 110, after putting into food, cover lid 102, at last the catch 113 of lid is turned down and buckled into the box body flanging and locks the box body and lid.

As shown in Figure 1, Figure 7, and Figure 8, a refrigerator includes a box body 4, a door body 2, and a door liner 3, and a card slot 114 is arranged on the door liner of the freezer or at least one inner side wall of the refrigerator, and the card slot The shape of the mobile multifunctional fresh-keeping box matches the cold storage device, and the cold storage device is built into the card slot when it is in a cold storage state. When the mobile fresh-keeping function is not needed, the cold storage device 103 and the EPS insulation board 104 can be removed, and the EPS insulation board 104 is installed in the limiting groove 105 of each sheet, and each sheet is assembled in the freezer through the card slot. On the door liner of the room, it plays the purpose of cold storage, energy saving and energy consumption reduction. At this time, the fresh-keeping box can be put into the refrigerator, and the fresh-keeping box is still in a sealed state, which can play an auxiliary fresh-keeping effect.

The bottom of the slot 114 is provided with a limiting boss 115 for fixing the sheet, so as to effectively fix the sheet.

When the mobile preservation function is not in use, open the hook 113 on the box cover 102, take out the plurality of sheets and the corresponding EPS insulation boards in sequence, and then insert the EPS insulation boards into the limit grooves 105 corresponding to the sheets. Afterwards, each sheet-shaped body is sequentially installed on the card slot of the door liner, assembled in place through the limiting boss, and the door liner is assembled on the door body of the freezer.

A method for keeping food fresh. The method uses a mobile multifunctional fresh-keeping box. The specific steps are as follows:
