In certain embodiments, the second heat transfer guide 320 is a thermal diode. It is understood that thermal diodes, also known as thermal diode heat pipes, allow heat flow in one direction (e.g., allow heat flow in the x2 direction) and do not allow heat flow in the opposite direction (e.g., do not allow heat flow in the opposite direction of x 2). Therefore, the heat guiding effect on the heat dissipation process of the refrigerating device 200 is realized, the reduction of heat absorption from the environment is avoided, and the operation energy efficiency of the heat absorption process of the refrigerating device 200 is improved.

The fourth side faces the refrigeration device 200, and can contact the refrigeration device 200 to conduct heat, and of course, a gap or a heat conducting component can be arranged between the fourth side and the refrigeration device 200 as required.

In certain embodiments, as shown in fig. 3 and 4, the first thermal shield 213 is positioned partially between the magnetic refrigeration material 211 and the electromagnet and separates the magnetic refrigeration material 211 from the electromagnet. Therefore, the heat of the electromagnetic part has small thermal interference on the magnetic refrigeration material 211, and the cold insulation effect of the magnetic refrigeration material 211 is better, so that the magnetic refrigeration material 211 can more efficiently and more durably cool the container part 100, the energy efficiency of the product is higher, and the fresh-keeping effect is more durable.

In this way, the first heat insulating member 213, the first heat transfer guide 310, and the second heat transfer guide 320 surround the magnetic refrigeration material 211, and can better protect the magnetic refrigeration material 211.

In the structure, when a certain current is applied to the electromagnetic element (specifically, the electromagnetic element 212E and/or the electromagnetic element 212F), a magnetic field is generated, the magnetic moment of the magnetic refrigeration material 211 changes from disorder to order along the magnetic field direction, the magnetic entropy decreases, the magnetic refrigeration material 211 releases heat, and the heat generated by the magnetic refrigeration material 211 is led out by the second heat transfer guide 320; when the electromagnetic element (specifically, the electromagnetic element 212E and/or the electromagnetic element 212F) is powered off or the current is weakened, the electromagnetic element removes or weakens the magnetic field, the magnetic moment of the magnetic refrigeration material 211 changes from ordered to disordered along the magnetic field direction, the magnetic entropy increases, and the magnetic refrigeration material 211 absorbs heat, at this time, the heat of the container component 100 is transferred to the magnetic refrigeration material 211 through the first heat transfer guide member 310, so that the temperature of the container component 100 is reduced. The above process is circulated, and the cooling device 200 continuously provides a cooling source to the container part 100 through heat exchange.

And through setting up first heat insulating part 213, in the whole course of product operation, magnetic refrigeration material 211 is kept warm by first heat insulating part 213, magnetic refrigeration material 211 can not absorb heat or release heat from its periphery at will and lead to the invalid acting in a large number, like this, in the whole course of operation of product, the thermal directionality is good, make refrigerating plant 200 can produce heat and absorb heat more high-efficiently, thus lower the temperature to container part 100 more high-efficiently, and this structure refrigerating plant 200 is little by the interference of heat of stagnation on every side, can realize absorbing heat and the switching of heat production more swiftly, thus promote the operation efficiency of whole kitchen utensil.

In some embodiments, as shown in fig. 2, the kitchen appliance has a housing 510, and the refrigeration device 200 and the container part 100 are accommodated in the housing 510, wherein the housing 510 is provided with a heat dissipation hole 511 adapted to dissipate heat of the refrigeration device 200. Like this, the heat that product self operation produced can in time be arranged outward, reduces the product self and produces the harmful effects that heat absorption capacity brought refrigerating plant 200 of heat for refrigerating plant 200 is more high-efficient to container part 100 heat absorption, promotes the product efficiency.

In some embodiments, as shown in fig. 2, the kitchen appliance has a housing 510, the refrigeration device 200 and the container part 100 are housed in the housing 510, and the refrigeration device 200 is located below the container part 100. Therefore, the refrigeration device 200 can absorb heat and cool the container part 100 from the lower side, and is more beneficial to improving the cold bubble effect and the fresh-keeping effect of the substances in the container part 100. And the structural form that the refrigerating device 200 and the container part 100 are distributed up and down is more beneficial to the lower gravity center of the prepared product, thereby being beneficial to the stability of the product, not easy to topple over, being beneficial to saving the width and the size of the product and realizing the more portability of the product.

Of course, the present invention is not limited to the configuration of the present embodiment, and in other embodiments, the refrigeration apparatus 200 and the container member 100 may be distributed in the left-right direction. Alternatively, in other embodiments, the refrigeration device 200 may be positioned on the upper side of the container part 100.

In this embodiment, in more detail, the upper portion of the cooling device 200 is provided with the first heat transfer guide 310. The lower portion of the cooling device 200 is provided with the second heat transfer guide 320. The first heat transfer guide 310 contacts and conducts heat with the outer bottom surface of the container part 100, and the bottom wall of the case 510 is formed as a base having one or more heat dissipation holes 511 formed therein at a position below the second heat transfer guide 320.

In some embodiments, a foot structure may be formed on the bottom wall of the housing 510 to support the housing 510, so that the bottom of the housing 510 is free from a gap for the heat dissipation holes 511 to dissipate heat more efficiently.

In some embodiments, as shown in fig. 2, the kitchen appliance has a housing 510, the refrigeration device 200 is accommodated in the housing 510, the housing 510 has a housing opening 512, the container part 100 has an opening 110, the opening 110 is disposed corresponding to and communicates with the housing opening 512, and the housing 510 has a housing cover 520 adapted to open or close the housing opening 512. The shell cover 520 opens the shell opening 512 so that the opening 110 of the container part 100 can be opened through the position of the shell opening 512, and a user can conveniently take and place substances in the container part 100; the cover 520 closes the opening 512, so that the opening 110 of the container 100 is correspondingly closed, which is more beneficial to keep the interior of the container 100 warm and fresh.

In some embodiments, as shown in fig. 2, the kitchen appliance is a thermal container having a liner and a thermal structure formed outside the liner (as can be understood with reference to the second thermal insulation member 400 shown in fig. 2), and the container member 100 is formed as a liner. Thus, the heat preservation performance of the container part 100 can be improved, the cooling efficiency of the container part 100 is higher, and the cold-bubble fresh-keeping effect is more durable.

In more detail, as shown in fig. 2, the heat insulation structure includes the second heat insulation member 400, and the second heat insulation member 400 is distributed outside the container component 100 and insulates heat of the container component 100, which has the advantages of simple structure and low cost, and achieves the purpose of insulating heat of the container component 100, and at the same time, the mutual inclusion of the structures such as the heat dissipation hole 511 on the housing 510 is better, so that the sealing and heat insulation requirements around the container component 100 are reduced, and the structure of the product is simplified.

For example, the second heat insulating member 400 may be heat insulating cotton, heat insulating rubber, or the like.

Further, a relief area is formed in the second heat insulating member, and the relief area is provided at a position opposite to the refrigeration apparatus 200. Thus, the second heat insulating member does not provide a heat insulating effect between the refrigeration apparatus 200 and the container member 100, so that the refrigeration apparatus 200 can efficiently cool the container member 100.

Of course, the form of the thermal insulation structure is not limited to the second thermal insulation member 400, and in other embodiments, a vacuum thermal insulation layer may be used as the thermal insulation structure for the liner.

In some embodiments, the kitchen appliance further includes an electrical storage device (e.g., a battery, etc.) electrically connected to the cooling device 200 and providing power to the cooling device 200. The power storage device is detachably provided in the kitchen appliance, or the power storage device is formed as an infrequently detachable component in the kitchen appliance.

Of course, the present embodiment is not limited to this, and in other embodiments, the power storage device may not be provided as needed.

In some embodiments, the kitchen appliance further includes an electrical interface (e.g., a power cord or power cord interface, etc.) that is electrically connected to the refrigeration unit 200. Therefore, the product can be used by plugging in electricity, has rich use forms and is simple to use and operate.

In any of the above embodiments, the kitchen appliance is a removable kitchen appliance, which may also be referred to as a portable kitchen appliance.

The specific embodiment is as follows:

as shown in fig. 2 to 4, the present embodiment provides a cold brewing cup having a housing 510, a cup body (i.e., container part 100), and a refrigerating device 200. A case opening 512 is provided at the upper part of the case 510, and a case cover 520 which can be opened and closed is provided at the case opening 512. The bottom wall of the housing 510 is formed as a base and is provided with heat dissipation holes 511. The bowl is received in the shell 510, and a second thermal insulation member 400 is disposed between a sidewall of the bowl and a sidewall of the shell 510. A refrigeration zone is formed between the bottom wall of the cup and the bottom wall of the shell 510, and the refrigeration device 200 is accommodated in the refrigeration zone. The refrigeration device 200 includes a magnetic refrigeration material 211, a first thermal shield 213 disposed around the magnetic refrigeration material 211, and electromagnets (i.e., electromagnets 212E and/or electromagnets 212F) disposed to the sides of the magnetic refrigeration material 211. The electromagnet is located outside the first heat insulator 213, and the first heat insulator 213 separates the electromagnet from the inside and the outside of the magnetic refrigerant 211. Below the magnetic refrigeration material 211 is distributed a second heat transfer guide 320 (specifically a set of thermal diode faces). The second heat transfer guide 320 corresponds to the heat dissipation hole 511, and the first heat transfer guide 310 (specifically, another thermal diode surface set) is distributed above the magnetic refrigeration material 211. The first heat transfer guide 310 corresponds in position to the bottom wall of the cup.

The first process is as follows: when the electromagnet is electrified, a magnetic field is generated, the magnetic moment of the magnetic refrigeration material 211 is changed from disorder to order along the direction of the magnetic field, the magnetic entropy is reduced, and the magnetic refrigeration material 211 releases heat. The heat generated by the magnetic refrigerant material 211 is conducted out of the apparatus by the set of thermal diode faces (second heat transfer guides 320).

And a second process: when the electromagnet is powered off, the magnetic field is removed, the magnetic moment of the magnetic refrigeration material 211 is changed from order to disorder along the direction of the magnetic field, the magnetic entropy is increased, and the magnetic refrigeration material 211 absorbs heat. The heat of the cup inside the device is transferred from the thermal diode face group (second heat transfer guide 320) to the magnetic refrigerant material 211.

The first and second cycles are performed, and the refrigerating device 200 provides cold energy to the cup body continuously through heat exchange.

In the cold-brewing cup provided in this embodiment, the magnetic refrigeration device 210 includes an electromagnet and a magnetic refrigeration material 211. The basic principle of magnetic refrigeration is utilized: in the process of excitation, the magnetic moment of the magnetic material is changed from disorder to order along the direction of a magnetic field, the magnetic entropy is reduced, and the thermodynamic knowledge shows that the magnetic working medium (namely the magnetic refrigeration material 211) releases heat outwards at the moment; in the demagnetizing process, the magnetic moment of the magnetic material is changed from ordered to disordered along the magnetic field direction, the magnetic entropy is increased, and at the moment, the magnetic working medium absorbs heat from the outside. Secondly, under the adiabatic condition, the magnetic working medium does not exchange heat with the outside, for example, the first heat insulation member 213 is used for heat insulation, so that the heat exchange between the magnetic refrigeration material 211 and the outside is less, the heat exchange is neglected, and in the process of excitation and demagnetization, the magnetic field mainly acts on the magnetic refrigeration material 211, so that the internal energy of the magnetic refrigeration material 211 is changed, and the temperature of the magnetic refrigeration material 211 is changed. The process of absorbing heat from the cup body and the process of releasing heat to the environment are formed, and the cup body is cooled. The technology has the advantages of high unit refrigeration efficiency, low energy consumption, few components, low working frequency, high reliability, no environmental pollution, small volume and the like.
