The inventive concept of the present application will be described in detail below in connection with exemplary embodiments.

According to a first aspect of the present application there is provided a thermal insulation barrel, as shown in fig. 1 and 2, the thermal insulation barrel comprising a barrel body 10 and a thermal storage block 20, the barrel body 10 comprising an inner cavity having an upper opening, the thermal storage block 20 comprising a housing 21 having a closed receiving cavity therein and a phase change material 22 disposed in the receiving cavity, wherein the thermal storage block 20 is capable of being placed in the inner cavity of the barrel body 10 along the upper opening or capable of being taken out from the inner cavity of the barrel body 10 through the upper opening.

In the embodiment of the present application, the barrel body 10 of the heat insulation barrel may have a double-layer structure or a single-layer structure. Illustratively, the tub body 10 of a double-layered structure includes an outer case and an inner case, and a heat insulation chamber is formed between the outer case and the inner case. Wherein, the heat insulation cavity is filled with heat insulation medium or vacuumized. Since the tub body 10 has a conventionally understood structure as will occur to those skilled in the art, a detailed description of the tub body 10 will not be provided herein.

The heat-insulating barrel is used as a heat-insulating device, and the heat exchange between the inside and the outside of the barrel body is less due to the heat-insulating effect of the heat-insulating cavity and the sealing effect of the barrel body and the barrel cover, so that the heat-insulating barrel can be used for insulating cold and heat. When food with higher temperature is placed, heat preservation is needed, and when food with lower temperature is placed, cold preservation is needed.

According to the embodiment of the application, the heat storage block 20 is arranged, and the phase change material in the heat storage block 20 can absorb or release a large amount of latent heat in the phase change process, so that the temperature in the heat preservation barrel can not be rapidly reduced or increased in the use process, the heat preservation or cold preservation function can be further enhanced, and the food in the heat preservation barrel can be kept at the expected temperature for a long time. Different types of phase change materials have different phase transition temperatures. Therefore, by filling different phase change materials in the heat storage block 20, foods in the heat preservation barrel can be kept at different temperatures, and different heat preservation or cold preservation requirements can be met.

In daily life, the heat preservation barrel with different heat preservation temperatures can be needed according to different requirements and application occasions. According to the general insulation requirements, the following two types can be roughly classified. First, it is desirable to maintain the food at an elevated temperature, for example, when it is desired to send a freshly prepared meal to a hospital caretaker, in which case the user often wishes to maintain the incubation temperature at 50-70 ℃ to avoid the meal becoming cool for a short period of time. For this purpose, a phase change material having a phase change temperature in the range of 50 ℃ to 70 ℃ may be provided in the thermal storage block 20. In this case, the user may heat the thermal storage block 20 to above the phase transition temperature in advance and put it into the thermal insulation tub. When the temperature in the heat preservation barrel is lower than the phase change temperature of the phase change material, the phase change material can release phase change latent heat, so that the food keeps at a higher temperature. The good heat storage of the phase change material is utilized, so that the phase change material is used as an additional heat source for providing heat for food. Second, the user desires to keep food in a low temperature state, for example, when taking a meal prepared in advance to a unit as a lunch, in order to avoid deterioration of the food due to an excessive temperature, the user desires to keep the food at a low temperature for a long period of time, for example, but not limited to, 3 ℃ to 5 ℃. For this purpose, phase change materials with a phase change temperature in the range of 3 ℃ to 5 ℃ above zero can be selected. The user may put the thermal storage block 20 into the refrigerator in advance to be cooled below the phase transition temperature and then put into the heat insulation tub. When the temperature in the heat-preserving container is higher than the phase-change temperature of the phase-change material, the phase-change material can absorb heat, so that food in the heat-preserving container is kept in a low-temperature state continuously. The application can be used for configuring the phase change materials with different phase change temperatures for the heat preservation barrel according to the demands of different users, so that the heat preservation barrel can be suitable for more use demands.

According to the application, the heat-preserving container can be a meal heat-preserving container. In an embodiment, the insulating bucket further comprises at least one hamper 30, the hamper 30 being able to be placed in the inner cavity of the bucket body 10 through the upper opening. In some embodiments, the cartridge 30 can be placed in a thermal bucket with the thermal block 20. In an exemplary embodiment, the number of cartridges 30 may be 2 or 3. According to some embodiments of the present application, the heat storage block 20 may be disposed between two adjacent cartridges, so as to ensure that the heating and heat preservation effects can be achieved for each cartridge.

In these embodiments, by providing a plurality of the food boxes 30, different kinds of meal can be stored separately, and thus it is possible to ensure that the taste of eating is not affected by the tainted taste due to the mixed food materials. In addition, the plurality of the food boxes 30 can be conveniently and separately contained as much as possible by a user when food is contained, so that the risk of food poisoning caused by mixing together food materials in a gram is avoided.

According to the present application, a plurality of the food serving boxes 30 can satisfy the holding requirement of holding a sufficient amount of foods of a sufficient variety.

In some embodiments, the plurality of cartridges 30 is a plurality, and the plurality of cartridges 30 can be stacked one above the other with the heat storage block 20. In other embodiments, the thermal block 20 is disposed between a plurality of cartridges 30. In these embodiments, the heat storage block 20 may be disposed below all the cartridges 30 or may be sandwiched between a plurality of cartridges 30, so that it is ensured that the food materials in the plurality of cartridges 30 can be influenced by the heat storage block 20 to have a good heat preservation effect.

In an embodiment, phase change material 22 is a solid-liquid phase change material. The solid-liquid phase change material has higher heat exchange efficiency and energy storage density, so that the heat storage block 20 is prevented from excessively occupying the volume of the barrel body 10 under the condition of meeting the heat preservation requirement.

In an exemplary embodiment, the solid-liquid phase change material may be paraffin.

According to the application, the phase change material 22 is arranged in the accommodating cavity formed by the shell 21, and certain volume change can occur in the phase change process, so that the accommodating cavity of the shell 21 is not completely filled with the phase change material 22, and therefore enough space can be reserved for phase change, the shell is prevented from deforming and even cracking.

The receiving chamber of the housing 21 according to the present application may be closed in a manner well known to those skilled in the art so that the solid-liquid phase change material does not penetrate out of the receiving chamber when it changes phase to a liquid state. For example, an opening may be provided partially in the housing 21, and the opening may be sealed by welding or bonding after the phase change material is filled into the accommodating chamber. In addition, the sealing part can be modified, for example, the welding part can be polished, so that the appearance of the product is not affected.

In an exemplary embodiment, the phase change material has a higher energy storage density and a higher thermal conductivity, and thus can be used as an excellent heat exchange material. As an example, the phase-change material may be a solid-liquid phase-change material, which may be paraffin, the phase-change material FSM-PCM67, or the phase-change material SL-58, and the energy storage density may range from 190J/g to 240J/g, so that a smaller amount of the phase-change material can achieve larger energy storage, thereby meeting the requirement of serving as an energy supply component. Taking phase change material SL-58 as an example, the weight of phase change material 22 required is 90g-100g per cubic decimeter of space. As an example, for a heat-preserving container with a capacity of 2L, a phase-change material with a weight of 180g-200g is provided, wherein the model of the phase-change material is SL-58, which can store about 42KJ of heat, and can continuously supplement heat to food for a long time, thereby effectively prolonging the heat-preserving time of the food.

According to the present application, the phase change material 22 has a phase change temperature of 50 ℃ to 70 ℃, further 55 ℃ to 60 ℃. By adding an extra heat source in the heat preservation barrel, the heat preservation for a long time is realized in a way of providing heat compensation for food. For example, in the case where the heat storage block 20 is not used, since the temperature can be maintained only by the heat of the food itself, the temperature of the food is lowered with the lapse of time, typically not more than 5 hours, and the temperature is lowered to 40 ℃, at which time the food has cooled. However, in the case of using the heat storage block 20, since the heat storage block 20 is provided as an additional heat source, the heat insulation performance of the heat insulation tub can be greatly improved, and the temperature of the food is reduced to about 55 c after 5 hours, and is reduced to about 40 c after 8 hours.

In an embodiment, the thermal block 20 has a shape conforming to the inner cavity of the tub body 10. In the exemplary embodiment, the inner cavity of the tub body 10 is cylindrical, and the corresponding heat storage block 20 is cylindrical. Of course, the present application is not limited thereto, and the inner cavity of the tub body 10 may be square, so that the corresponding heat storage block 20 is also formed in a square shape. However, the embodiment of the present application is not limited thereto, and the shape of the thermal block 20 may be different from the shape of the inner cavity of the tub body 10. For easy taking, the external dimension of the heat storage block 20 may be slightly smaller than the dimension of the inner cavity of the tub body 10.

In an embodiment, the heat storage block 20 can be engaged or fitted to the bottom of the tub body 10. In these embodiments, since heat is easily lost from the gap between the tub body and the sealing cover, and the bottom is relatively far from the upper opening of the tub body 10, the heat storage block 20 is fitted in the area of the tub body 10 near the bottom, so that it is possible to ensure that the heat inside the tub body is not lost ineffectively, thereby being able to extend the insulation time of the insulation tub to some extent.

In an embodiment, the material of the housing 21 may be stainless steel, carbon steel, aluminum alloy, titanium or titanium alloy. The material of the food box 30 is food grade stainless steel, such as 304 stainless steel or 316 stainless steel. The material of the housing 21 is not limited in this application and other materials may be selected by those skilled in the art in light of the teachings of this application.

In an embodiment, the housing 21 may have a handle to facilitate lifting, so that the heat storage block 20 can be easily taken out of the tub body 10 for heating or cooling.

In an embodiment, the thermal insulation tub further includes a sealing cover capable of blocking or opening an upper opening of the tub body 10. The sealing cover comprises a cover body and a sealing ring sleeved on the cover body, and the sealing ring can be extruded in a gap between the cover body and the barrel body.

According to the application, the heat-preserving container can be a heat-preserving lifting pot, and in the embodiment, the heat-preserving container further comprises a handle, and the handle is arranged on the outer side of the edge of the upper opening of the container body 10, so that the lifting operation can be facilitated.

According to the use method of the heat-preserving barrel, before use, heat can be applied in advance to enable the temperature of the heat storage block 20 to be higher than the phase transition temperature of the heat storage block, and the heat storage block and the hamper 30 are respectively arranged in the inner cavity of the barrel body 10, so that the heat-preserving time of food materials in the hamper 30 of the heat-preserving barrel is prolonged by releasing latent heat. Specifically, the heat storage block 20 may be placed in a water bath and heated to a temperature above the phase transition temperature thereof, then taken out and placed at the bottom of the tub body 10, then the hamper 30 is placed above the heat storage block 20, and finally the upper opening of the tub body 10 is sealed with a sealing cover.

Although embodiments of the present application have been described in detail hereinabove, various modifications and variations may be made to the embodiments of the present application by those skilled in the art without departing from the spirit and scope of the present application. It will be appreciated that such modifications and variations will still fall within the spirit and scope of the embodiments of the present application as defined by the appended claims, as will occur to those skilled in the art.
