Description

Heat preservation utensil and portable's heat preservation utensil thereof

Technical Field

The invention relates to a method for regulating temperature of a heat preservation appliance with an inner wall and an outer wall, which comprises a method for heat transfer between the inner wall and the outer wall of a cavity of the heat preservation appliance.

The invention also relates to a multifunctional temperature-adjustable heat preservation appliance, which comprises an outer wall, an inner wall, a heat transfer medium and the like. Is characterized in that the heat transfer medium between the inner wall and the outer wall of the heat preservation appliance is in a controlled state, thereby realizing reliable heat preservation and heat dissipation.

Background

In real life, people are used to keep the temperature of objects by using heat preservation appliances all the year round, particularly in hot summer or cold winter, wherein the vacuum heat preservation appliances with the inner and outer wall structures have good heat preservation effect. However, the vacuum heat-insulating appliance can insulate heat, and simultaneously can block the heat energy transmission between the object in the appliance and the outside, and can not be heated or cooled rapidly.

For example, when people do outdoor activities in cold winter, the portable vacuum heat preservation device can not be used for warming hands and feet although carrying hot drinks, and when people need to drink, the people are often too hot to drink immediately; when people do outdoor activities in hot summer, in order to keep the freshness of the beverage, people (especially mothers of babies) often carry low-temperature beverage with a vacuum heat-preservation device, and when the low-temperature beverage needs to be drunk, the low-temperature beverage cannot be drunk by babies immediately; when people open the sealing cover of the heat preservation appliance so as to heat or cool, the beverage and the air generate convection, so that bacteria in the air easily pollute the beverage, and particularly in an environment with poor air quality, the pollution is more serious, and meanwhile, the risks of splashing and scalding exist; if mothers use a non-insulated device to feed the beverage to the baby, the beverage in the container becomes gradually cold with the lapse of time, which is not good for the health of the baby because the baby swallows slowly and often needs to feed for a long time. This causes various inconveniences to the user.

Therefore, there is a strong need in the market for a thermal insulation device that has both a reliable thermal insulation function and a function of raising and lowering temperature in a sealed state. In recent years, efforts have been made to realize the temperature raising and lowering function of a thermal insulating device (particularly, a vacuum thermal insulating device), but there is no product having such a function that is reliable in function, stable in performance, and widely accepted in the market. Chinese patent publication (CN204520141U) discloses a method for realizing the temperature raising and lowering function of a vacuum heat preservation apparatus, but the following disadvantages exist: one end of the metal sheet is a free end, so that the metal sheet is in the optimal heat preservation and radiation state only in a static and vertical state (in a positive or negative state); when the metal sheet is in the states of inclination, transverse placement, movement and the like, the metal sheet is in an uncontrolled state, and the free end of the metal sheet is sometimes in contact with or broken from the shell, so that the heat preservation and the heat dissipation performance are affected, and the metal sheet is inconvenient to carry.

Disclosure of Invention

In order to overcome the defects and inconvenience of the prior art, the invention aims to provide a method for manufacturing a heat preservation appliance which has a reliable heat preservation function and a reliable heating and cooling function.

Accordingly, another object of the present invention is to provide a multifunctional thermal insulating device which has both reliable thermal insulating function and reliable temperature raising and lowering function in a sealed state.

Because the invention provides a heat preservation appliance which can be heated and cooled in a sealed state, if the heating and cooling speed of liquid in the heat preservation appliance needs to be increased, the problem can be solved by immersing the outer wall of the heat preservation appliance into high-temperature or low-temperature liquid; meanwhile, in cold weather, the heat dissipation function of the heat preservation device can be used as a heating device with adjustable temperature, and the heat preservation sleeve is arranged on the outer side of the heat preservation device, so that the heat preservation device is more convenient to use; the heat preservation device with the permanent magnet embodiment of the invention also has the function of magnetizing water.

As shown in fig. 3-2, when the heat-retaining tool is laid across, the controlled heat transfer medium A3 is still in contact with the inner wall 2, but when one moves, there is a possibility that the controlled heat transfer medium A3 is out of contact with the inner wall 2 due to the inertial force generated by the movement. Therefore, as shown in fig. 3-3, the first embodiment of the invention is in a reliable heat dissipation state when the bottom of the heat preservation device faces upwards and the included angle < a or < b between the central axis and the vertical line is less than 90 °.

The controlled heat transfer medium a3 of the present invention may be of various cross-sections, various shapes, may be provided anywhere between the inner and outer walls, and may be provided in several quantities.

Fig. 5-2 is a schematic view of a controlled heat transfer medium a3 according to a third embodiment of the present invention. Fig. 5-3 is a transverse sectional view of a controlled heat transfer medium a3 taken along line III-III in fig. 5-2 according to a third embodiment of the present invention.

In the first and second embodiments of the present invention, the controlled heat transfer medium A3 is in sliding fit with the outer wall 1 or the inner wall 2, and there is a conversion that the controlled heat transfer medium A3 is stuck to the outer wall 1 or the inner wall 2 due to expansion and contraction, and heat preservation and heat dissipation can be performed again after temperature balance. The fourth embodiment of the present invention employs the elastic structure 6 to avoid the above locking phenomenon. Fig. 6 shows a thermal insulation device with an elastic structure according to a fourth embodiment of the present invention, which comprises: the heat insulation device comprises an outer wall 1, an inner wall 2, a controlled heat transfer medium A3, a heat transfer medium B4 and an elastic structure 6, wherein the elastic structure 6 is made of elastic heat conduction materials and can be elastic structures such as sheets, strips or springs, the controlled heat transfer medium A3 is elastically attached to the outer wall 1 through the elastic structure 6, and the heat transfer medium B4 is a part of the existing inner wall 2 of the heat insulation device. When the controlled heat transfer medium A3 expands due to heat, the controlled heat transfer medium A3 does not seize the outer wall 1 or the inner wall 2 due to thermal expansion due to the presence of the elastic structure 6. Fig. 6 shows a heat preservation state, and due to the action of gravity, the controlled heat transfer medium A3 only contacts with the outer wall 1, and the heat preservation device is in a heat insulation state between the inner wall and the outer wall, so that the heat preservation device is in a reliable heat preservation state. As shown in fig. 6-1, when the thermal insulation means is tilted, the controlled heat transfer medium a3 is in contact with only the outer wall 1 by gravity, so that the thermal insulation means is still in a reliable thermal insulation state. As shown in fig. 6-2, when the heat preservation apparatus is placed horizontally, the controlled heat transfer medium A3 is not in contact with the inner wall 2, and when people move, because the controlled heat transfer medium A3 is elastically attached to the outer wall 1, the generated friction force can avoid the possibility that the controlled heat transfer medium A3 is in contact with the inner wall 2 due to the inertia force generated by the movement. Therefore, the fourth embodiment of the invention is in a reliable heat preservation state when the bottom of the heat preservation device is downward, inclined, transversely placed and people move.

The fourth embodiment of the present invention is the same as the first, second and third embodiments except that the elastic structure 6 is added.

Fig. 7 is a schematic view of a controlled heat transfer medium a3 with an elastic structure according to a fourth embodiment of the present invention. Fig. 7-1 is a cross-sectional view of a controlled heat transfer medium a3 with an elastic structure of a fourth embodiment of the present invention, taken along the line IV-IV in fig. 7.

As shown in fig. 8-1, when the heat retaining device is tilted, the controlled heat transfer medium a3 still contacts with the heat transfer medium B4 under the action of gravity, so that the heat retaining device is still in a reliable heat dissipation state. As shown in fig. 8-2, when the heat preservation apparatus is placed horizontally, the controlled heat transfer medium A3 still adheres to the heat transfer medium B4, and when people move, because the controlled heat transfer medium A3 is elastically adhered to the outer wall 1, the generated friction force can prevent the controlled heat transfer medium A3 from being separated from the heat transfer medium B4 due to the inertia force generated by the movement. Therefore, the fourth embodiment of the present invention is in a reliable heat dissipation state when the bottom of the thermal insulator is upward, inclined, and horizontally placed.

Fig. 8-3 are schematic views showing another structure of the thermal insulation device with an elastic structure according to the fourth embodiment of the present invention, which comprises: the heat exchanger comprises an outer wall 1, an inner wall 2, a controlled heat transfer medium A3 and an elastic structure 6, wherein the elastic structure 6 is made of elastic heat conduction materials and can be elastic structures such as sheets, strips or springs, and the controlled heat transfer medium A3 can be simultaneously and elastically attached to the outer wall 1 and the inner wall 2 through the elastic structure 6. When the controlled heat transfer medium A3 is at the bottom of the heat preservation apparatus (as shown in the position of '3 a' in figures 8-3), because the controlled heat transfer medium A3 is elastically attached to the outer wall 1, the generated friction force can avoid the possibility that the controlled heat transfer medium A3 is contacted with the inner wall 2 due to the inertia force generated by the movement, the controlled heat transfer medium A3 is only contacted with the outer wall 1, the inner wall and the outer wall of the heat preservation apparatus are in a heat insulation state, and the heat preservation apparatus is in a reliable heat preservation state. The structure can make the controlled heat transfer medium A3 generate displacement by slightly knocking the upper and lower parts of the heat preservation appliance and utilizing the inertia force, thereby carrying out the conversion of heat preservation and heat dissipation states. When the controlled heat transfer medium A3 is displaced to the position 3 shown in the figure 8-3 by the light-bump heat preservation appliance, the controlled heat transfer medium A3 is elastically attached to the outer wall 1 and the inner wall 2 at the same time, and the heat preservation appliance is in a reliable heat dissipation state.

As shown in fig. 9, a heat-insulating device with a stopper structure according to a fifth embodiment of the present invention includes: the heat transfer device comprises an outer wall 1, an inner wall 2, a controlled heat transfer medium A3, a heat transfer medium B4, an elastic structure 6 and a limiting structure 7, wherein the limiting structure 7 is made of an elastic material.

The following is a case where the axial stopper force generated by the stopper structure 7 is equal to or less than the difference between the gravity and the frictional resistance of the heat transfer medium.

Fig. 9 shows a heat preservation state, the controlled heat transfer medium A3 only contacts with the outer wall 1 due to gravity, the heat insulation state is between the inner wall and the outer wall of the heat preservation device, and the heat preservation device is in a reliable heat preservation state. As shown in FIGS. 9-1 and 9-2, when the heat preservation apparatus is inclined, laid transversely, or even the bottom of the heat preservation apparatus is inclined upwards for a certain angle, the controlled heat transfer medium A3 will not contact the inner wall 2 under the action of gravity, friction and the limiting structure 7, and the heat preservation apparatus is in a reliable heat preservation state. When people move, the controlled heat transfer medium A3 can not contact with the inner wall 2 under the action of gravity, friction and the limiting structure 7. Therefore, the fifth embodiment of the invention is in a reliable heat preservation state when people exercise, wherein the bottom of the heat preservation device faces downwards, inclines and horizontally, and the bottom of the heat preservation device faces upwards and inclines for a certain angle.

Fig. 10 is a schematic view of a controlled heat transfer medium a3 with a limiting structure and an elastic structure according to a fifth embodiment of the present invention. Fig. 10-1 is a transverse sectional view of a controlled heat transfer medium a3 with a stopper structure and a resilient structure of a fifth embodiment of the present invention, taken along the line V-V in fig. 10.

FIGS. 11, 11-1 and 11-2 are schematic views showing a heat retaining device with a stopper structure according to a fifth embodiment of the present invention in a heat dissipating state.

Fig. 11 is a schematic view showing a heat preservation device with a limiting structure in a heat dissipation state according to a fifth embodiment of the present invention, in which a central axis of the heat preservation device is perpendicular to the ground and a bottom of the heat preservation device is upward, a controlled heat transfer medium A3 slides downward along the limiting structure 7 to be attached to a heat transfer medium B4 due to gravity, and heat is transferred through an inner wall 2 of the heat preservation device, the heat transfer medium B4, the controlled heat transfer medium A3, the elastic structure 6, and the outer wall 1, so that the heat preservation device is in a reliable heat dissipation state. As shown in fig. 11-1 and 11-2, when the heat preservation apparatus is inclined, laid horizontally, or even the bottom of the heat preservation apparatus is inclined downward at a certain angle, the controlled heat transfer medium a3 still elastically contacts with the heat transfer medium B4 under the action of friction and the axial force of the limiting structure 7, and the heat preservation apparatus is in a reliable heat dissipation state. When people move, under the action of friction force and the axial force of the limiting structure 7, the controlled heat transfer medium A3 can be prevented from being separated from the heat transfer medium B4 due to the inertia force generated by the movement. Therefore, the fifth embodiment of the invention is in a reliable heat radiation state when the bottom of the heat preservation device is upward, inclined, transversely placed, the bottom of the heat preservation device is downward and inclined for a certain angle and people do exercises.

The following is a case where the axial restraining force generated by the restraining structure 7 is larger than the difference between the gravity and the frictional resistance of the heat transfer medium.

As shown in fig. 12, when the thermal insulation device is in a thermal insulation state, i.e. the bottom of the thermal insulation device faces upward and the central axis is perpendicular to the ground, the position of the controlled heat transfer medium A3 cannot be changed by gravity due to the axial limiting force of the limiting structure 7, the controlled heat transfer medium A3 does not contact with the inner wall 2, and the thermal insulation device is in a reliable thermal insulation state.
