Description

Technical Field

[0001] The utility model belongs to the technical field of household appliances and relates to a thermos cup capable of solid-gas-liquid phase change and electromagnetic refrigeration and heating. Background Art

[0002] Traditional thermos cups mainly use the low heat transfer characteristics of vacuum insulation layer, which has no heat conduction and no convection, as a technical principle to delay the heat dissipation of the water in the cup to the environment, so as to keep the water in the cup warm for a long time. Due to the difference in the material and sealing effect of thermos cups, the insulation effect is also different, but the effective insulation time of 100℃ boiling water dropping to 60℃ is actually within 3 to 7 hours, and the insulation time of 100℃ boiling water dropping to 30℃ is only 5 to 10 hours. If the water is drunk during the insulation period, the insulation time will be very short.

[0003] Although the thermos cups on the market can basically meet people's needs for water insulation, in fact they are still far from meeting people's ideal pursuit of insulation effect. This is mainly reflected in the following three points:

[0004] 1. During the effective period, the water temperature is not always suitable for drinking;

[0005] 2. The water temperature in the thermos cup cannot be controlled, that is, it does not simply keep warm, but actively controls the temperature of the thermos cup from 30°C to 100°C, both steplessly heating and cooling it down according to the needs of the user;

[0006] 3. If the lid of the water cup is opened during the effective time, the effective insulation time for the second drinking will be greatly shortened.

[0007] Therefore, there is an urgent need for an energy-saving and efficient thermos cup that can solve the above problems. Utility Model Content

[0008] The technical solution adopted by the utility model to solve the technical problem is: a solid-gas-liquid phase change and electromagnetic refrigeration heating thermos cup, comprising: an inner liner, the outer wall of the inner liner is wrapped with an electromagnetic heating and refrigeration substructure layer, a solid-liquid phase change layer, and a gas-liquid heat transfer submodule layer in sequence from the inside to the outside; the electromagnetic heating and refrigeration substructure layer is made of a magnetic arc plate, and a coil ring cable structure is arranged in the magnetic arc plate. When the electromagnetic heating and refrigeration substructure layer is magnetized, the magnetic moment order increases, the magnetic entropy decreases, the temperature rises, and heat is released to the inner liner; when the electromagnetic heating and refrigeration substructure layer is demagnetized, the magnetic moment order decreases, the magnetic entropy increases, the temperature decreases, and heat is absorbed from the inner liner; the solid-liquid phase change layer is filled with a solid-liquid phase change material filler, and the solid-liquid phase change layer generates a phase change when absorbing and releasing heat, thereby storing heat or releasing heat; the inner liner and the electromagnetic heating and refrigeration substructure layer, the electromagnetic heating and refrigeration substructure layer and the solid-liquid phase change layer, and the solid-liquid phase change layer and the gas-liquid heat transfer submodule layer are respectively connected by thermal conduction;

[0009] The thermos cup is also provided with a battery and a control switch. The battery is electrically connected to the coil ring cable structure through the control switch. The control switch controls the battery to supply power to the coil ring cable structure and converts direct current into alternating current to achieve the effect of paramagnetic heat release and reverse magnetic heat absorption in the magnetic field constructed by the alternating current.

[0010] Preferably, a first enhanced heat exchange fin is provided between the electromagnetic heating refrigeration substructure layer and the inner tank, and a second enhanced heat exchange fin is provided between the electromagnetic heating refrigeration substructure layer and the solid-liquid phase change layer; the fins can enhance the effects of convection and heat conduction heat exchange.

[0011] Preferably, the electromagnetic heating refrigeration substructure layer and the solid-liquid phase change layer are arranged alternately in a modular manner in a vertical plane, and the electromagnetic heating refrigeration substructure layer modules and the solid-liquid phase change layer modules are alternately adhered to the outer wall of the inner tank; the electromagnetic heating refrigeration substructure layer and the solid-liquid phase change layer arranged alternately can meet the requirement that when the temperature of the inner tank is high, the solid-liquid phase change layer directly phase changes to absorb heat, and the electromagnetic heating refrigeration substructure layer absorbs heat through reverse magnetic field, and dissipates heat through latent heat and sensible heat, thereby quickly cooling the inner tank.

[0012] Preferably, the gas-liquid heat transfer submodule layer is provided with a gas-liquid heat transfer inner layer and a gas-liquid heat transfer outer layer in sequence from the inside to the outside, the gas-liquid heat transfer inner layer is filled with a gas-liquid phase change material filler, the gas-liquid heat transfer outer layer is a vacuum layer, the top of the gas-liquid heat transfer inner layer is connected with the top of the gas-liquid heat transfer outer layer through an air hole, a control valve is provided at the air hole, the bottom of the gas-liquid heat transfer inner layer is connected with the bottom of the gas-liquid heat transfer outer layer through a liquid wick, and the liquid wick is electrically connected to the battery through a control switch; when the control valve at the air hole is opened, heat is dissipated to the gas-liquid heat transfer submodule layer, and the gas-liquid heat transfer outer layer is connected to the gas-liquid heat transfer inner layer. The heat transfer medium in the liquid phase change cavity evaporates due to heat, and the gas molecules move upward. Since the control valve is open at this time, the gas molecules will enter the vacuum layer. The movement of the gas molecules in the vacuum layer makes the thermal resistance of the vacuum layer much larger, so the heat is dissipated to the wall to the external environment (heat sink). In this process, the gas molecules in the vacuum cavity continuously release heat and the liquid molecules continuously accumulate. When the control valve at the pore is closed, the pressure in the vacuum layer is greater than the gas-liquid heat transfer inner layer. The liquid wick works to transfer the liquid in the vacuum layer back to the gas-liquid heat transfer inner layer to complete the cooling of the inner tank.

[0013] More preferably, the thermos cup includes a cup cover, a display screen, and a temperature sensor, wherein the temperature sensor is used to measure the temperature of the inner tank, and the display screen and the temperature sensor are electrically connected to a control switch, respectively; the water temperature in the inner tank is controlled by presetting the time and the temperature on the display screen.

[0014] More preferably, a contact switch is provided at the cup lid, and the contact switch is linked to the control valve. When the cup lid is closed, the contact switch and the control valve are closed; when the cup lid is closed, the circulation communication channel between the inner layer of gas-liquid heat transfer and the outer layer of gas-liquid heat transfer is closed, thereby improving the thermal insulation performance of the inner liner.

[0015] Preferably, the solid-liquid phase change material filled in the solid-liquid phase change layer is filled layer by layer from the inside to the outside in a multi-layer coaxial sleeve shape, and the solid-liquid phase change material is: composite nano-carbon particles or porous graphite foam; multi-layer annular sleeve filling, so that the solid-liquid phase change material in the innermost layer undergoes phase change first, and then conducts heat to the outermost layer layer by layer, ensuring the uniformity of heat absorption and heat dissipation on the entire inner wall of the liner, as well as the stepped nature of heat conduction from the inside to the outside.

[0016] Preferably, the electromagnetic heating and refrigeration substructure layer uses a magnetic arc plate that is in a tile shape and surrounds the outer wall of the inner liner. The material of the magnetic arc plate is: an alloy or compound of a 3d transition metal; the material of the magnetic arc plate includes: LaCaNaMnO, LaFeCoSi; multiple tile-shaped magnetic arc plates are spliced ​​into a complete cylindrical sleeve on the outside of the inner liner, which facilitates the fitting of the magnetic arc plate and the inner liner, and can also be arranged at different heights and different intervals according to different needs to meet the needs of different thermos cups.

[0017] The beneficial effects of the utility model are:

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the relevant technologies in the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] refer to Figures 1 to 6, a solid-gas-liquid phase change and electromagnetic refrigeration heating thermos cup, comprising an inner liner 1, the inner liner 1 contains drinking water, the inner liner 1 adopts a heat-conducting wall surface, the outer layer of the inner liner 1 is wrapped with an electromagnetic heating and refrigeration substructure layer 2, or the side wall of the inner liner 1 is provided with an electromagnetic heating and refrigeration substructure layer 2. A coil ring cable structure 5 is provided on the electromagnetic heating and refrigeration substructure layer 2, and when a magnetic field is constructed by alternating current through a battery 6 and a contact connection, the magnetic arc plate absorbs or releases heat. The magnetic material of the magnetic arc plate of this embodiment can be an alloy or compound of a 3d transition metal, such as LaCaNaMnO, LaFeCoSi, etc. This embodiment utilizes the magnetocaloric effect of the magnetic arc plate. That is, the thermal phenomenon caused by the change in the magnetic moment order of the magnetic material under a changing magnetic field. When the magnetic material is magnetized, the magnetic moment order increases, the magnetic entropy decreases, the temperature rises, and heat is released to the outside; when demagnetized, the magnetic moment order of the magnetic material decreases, the magnetic entropy increases, the temperature decreases, and heat is absorbed from the outside. In the magnetic field of alternating current, heat is released in the paramagnetic direction and heat is absorbed in the antimagnetic direction.

[0028] The control switch 7 is used to control the switch of AC power supply, which converts the battery power from DC to AC and then transmits it to the electromagnetic heating and refrigeration substructure layer 2. The solid-liquid phase change layer 3 is filled with porous graphite foam composite phase change material, which absorbs the heat of the water in the inner liner 1 or releases the stored heat to the water in the inner liner 1. The first enhanced heat exchange fin 8 is used to enhance the heat conduction and heat exchange between the inner liner 1 and the electromagnetic heating and refrigeration substructure layer 2. The second enhanced heat exchange fin 9 enhances the convection and heat conduction between the electromagnetic heating and refrigeration substructure layer 2 and the solid-liquid phase change layer 3. The gas-liquid heat transfer submodule layer 4, the control valve 13, and the liquid wick 14 cooperate to perform heat conduction and heat exchange between the solid-liquid phase change layer 3 and the gas-liquid heat transfer submodule layer 4. The control valve 13 in the gas-liquid heat transfer submodule layer 4 is opened, and the liquid wick 14 works. The control valve 13 is closed, and the liquid wick 14 stops working. The vacuum heat insulation heat exchange submodule 19 in the gas-liquid heat transfer submodule layer 4 includes an annular booster plate 20, which is airtightly connected to the side wall of the gas-liquid heat transfer outer layer 11, and can be moved in the vertical direction under force, and together with the bottom of the thermos cup, it forms a vacuum chamber. The part above the height of the annular booster plate 20 on the outer wall of the thermos cup can be made of soft wall material, and the soft wall material can be squeezed externally to deform the part above the annular booster plate 20, thereby squeezing the annular booster plate 20 downward to compress the vacuum chamber; or a handle that can be pulled up and down is set on the upper part of the thermos cup, and the handle is pressed down while driving the annular booster plate 20 downward to compress the vacuum chamber, promote the transformation of gas into liquid, and then compress the vacuum chamber to promote the condensation of the heat transfer medium, ensuring that the effect is still good after multiple cycles. The display screen 16 and the temperature sensor 17 are used to detect the temperature of the inner liner 1.

[0029] Example

[0030] Solution 1: The initial state is to use the inner tank 1 of this embodiment to carry hot water at 100°C, in order to quickly reduce the temperature of the water to the required temperature, such as 40°C. This embodiment will transfer heat to the solid-liquid phase change layer 3 close to the wall of the inner tank 1 through heat conduction on the wall of the inner tank 1, and transfer heat to the gas-liquid heat transfer submodule layer 4 through latent heat and sensible heat. The heat transfer medium in the gas-liquid heat transfer submodule layer 4 evaporates due to heat, and the gas molecules move upward. At this time, the control valve 13 is opened, and the gas molecules will enter the vacuum cavity. The movement of the gas molecules in the vacuum cavity makes the thermal resistance of the vacuum cavity much larger, so the heat is dissipated to the wall to the external environment (heat sink). In this process, the gas molecules in the vacuum cavity continuously release heat, and the liquid molecules continuously accumulate. The control valve 13 is closed. At this time, the pressure in the vacuum cavity is greater than the gas-liquid heat transfer inner layer 10, and the liquid wick 14 works to transfer the liquid in the vacuum cavity back to the gas-liquid heat transfer inner layer 10, completing the water cooling of the inner tank 1.

[0031] Solution 2: As time goes by, the water temperature in the inner tank 1 will be lower than the required 40°C or the water temperature injected into the inner tank 1 will be lower than the required temperature. At this time, the water in the inner tank 1 needs to be heated. First, turn on the control switch 7 as required, and the positive alternating current in the coil will generate a positive magnetic field. The magnetic entropy of the magnetic arc plate in the magnetic field will decrease, and the thermal entropy will increase. The magnetic arc plate will release heat, and the inner tank wall will fit tightly with the magnetic arc plate (evenly spaced inner wall surface), and the heat will be transferred to the drinking water through heat conduction. During the heating process, the control valve 13 and the liquid wick 14 are always kept closed.

[0032] Solution 3: There is a demand for cooling water in summer. Set the control switch 7 to reverse alternating current, and the coil forms a reverse magnetic field with the reverse current. The magnetic entropy of the magnetic arc plate in the magnetic field will increase, and the thermal entropy will decrease. The magnetic arc plate absorbs heat, and the wall of the inner tank 1 fits tightly with the magnetic arc plate (evenly spaced inner wall surface), and absorbs the heat of the drinking water through heat conduction. When not drinking, disconnect the control switch 7, the magnetic field disappears, and the magnetic arc plate transfers heat to the wall of the gas-liquid heat transfer submodule layer 4 due to the temperature difference. The heat transfer medium in the gas-liquid heat transfer submodule layer 4 evaporates due to the heat, and the gas molecules move upward. At this time, open the control valve 13, and the gas molecules will enter the vacuum chamber. The movement of the gas molecules in the vacuum chamber makes the thermal resistance of the vacuum chamber much larger, so the heat is dissipated to the wall to the external environment (heat sink). In this process, the gas molecules in the vacuum chamber continuously release heat, and the liquid molecules continuously accumulate. Close the control valve 13. At this time, the pressure in the vacuum chamber is greater than the gas-liquid heat transfer inner layer 10, and the liquid wick 14 works to transfer the liquid in the vacuum chamber back to the gas-liquid heat transfer inner layer 10, and the heat is dissipated to the heat sink.

[0033] It is worth noting that Scheme 1 can be coupled with Scheme 3 to achieve efficient and rapid cooling. When the temperature sensor 17 detects that the temperature of the drinking water reaches 40°C, the control switch 7 will be automatically disconnected. When the cup cover 15 is rotated to open the contact switch 18 and the pressure inside the cup is connected to the atmospheric pressure when the cup top is opened to drink water, the control switch 7 will also be automatically disconnected. When there is no need to drink the water in the cup, the connecting channel between the vacuum cavity and the gas-liquid heat transfer inner layer 10 is completely closed to improve the heat preservation performance of the cup. In addition, the drinking cup mouth uses a low thermal conductivity material, and the phase change material in the solid-liquid phase change layer 3 can be composited with nano-carbon particles or porous graphite foam.

[0034] In this embodiment, the gas-liquid-solid three-phase phase change quickly reduces the temperature of the drinking water in the inner liner of the thermos cup to an appropriate temperature; the alternating current constructs positive and negative magnetic fields to control the magnetic arc plate to absorb and release heat, which can flexibly cool and heat according to demand.

[0035] To sum up, the utility model controls the heat absorption and release of the magnetic arc plate through the gas-liquid-solid three-phase phase change and the alternating current to construct the positive magnetic and reverse magnetic fields, thereby realizing the rapid cooling, heating and insulation of the thermos cup, solving the technical problems that the thermos cup can only be drunk once at the appropriate temperature and needs to be rinsed with cold water for cooling, and meets people's demand for controllable drinking water temperature in the thermos cup. Therefore, the utility model has broad application prospects.

[0036] It should be emphasized that the above are only preferred embodiments of the present invention and do not constitute any form of limitation to the present invention. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
