BACKGROUND OF THE INVENTION
The present invention relates to a heating glove having a heating function, and more particularly to a heating glove suitable for work on a frozen object.
[0002]
[Prior art]
As a conventional heating glove having a heating function, a glove with a built-in heater such as a heating wire is known.
[0003]
[Problems to be solved by the invention]
When a conventional heating glove is applied to a work for a frozen object, the following problems may occur.
That is, for example, when applied to the work of fresh food such as cutting frozen tuna, the surface of the fresh food is locally thawed by the heat of the heater incorporated in the heating glove, thereby discoloring the thawed portion. May cause deterioration of freshness.
[0004]
In addition, even in general frozen work, sticking between a frozen object and a glove or a frozen object may occur due to local thawing and refreezing of the frozen object due to the heat of a heater built in the heating glove. is there.
Then, this invention makes it a subject to provide the efficient heating glove which can prevent the local thawing | defrosting of frozen material.
[0005]
[Means for Solving the Problems]
To achieve the above object, the present invention provides a hand cover portion that covers a user's hand, and a heat generating surface that is provided in the hand cover portion and generates heat by the Peltier effect and absorbs heat by the heat absorbing surface. There is provided a heating glove comprising an electrothermal element that heats the inside of the glove with the generated heat and cools at least a part of the outside of the glove by absorbing heat from the heat absorbing surface.
[0006]
By using an electrothermal element that performs heat transfer in this manner for heating the inside of the glove, it becomes possible to cool at least a part of the outside of the glove at the same time. In addition, it is possible to prevent local thawing of the frozen material due to contact with the heating gloves. That is, according to the present invention, it is possible to provide an efficient heating glove suitable for an operation of handling a frozen material, in which a single thermoelectric element is shared for both heating inside the glove and cooling outside the glove.
[0007]
Here, it is used that the hand cover portion is provided with a layer of a heat radiating member provided in contact with the heat generating surface of the electric heating element and diffusing heat conducted from the heat generating surface to the inside of the glove. It is preferable when performing uniform heating of a person's hand.
Further, when providing the heat dissipation member in this way, as the heat dissipation member, each of the cap-shaped metal member that covers the terminal node of each finger, and the cylindrical metal member that each covers the remaining node of each finger, It is also preferable to provide a plurality of metal members each covering the palm.
[0008]
By doing in this way, a heat radiating member can be used for both uniform heating of a user's hand, and user protection, such as protection from the blade at the time of a cutting operation. That is, according to the present invention, a heating glove that also needs to be protected from such a blade or the like can be realized with an efficient structure.
Moreover, in the above heating glove, it is good for the said electrothermal element to cool at least each fingertip abdominal part outside a glove. By doing in this way, local thawing | decompression of the frozen thing by the fingertip part which often touches a frozen thing in various forms of work can be prevented.
[0009]
Furthermore, if a temperature control unit that controls on / off of power feeding to the electric heating element according to the temperature inside the glove is provided, heating at an appropriate temperature can be performed, and excessive heating is performed. This will prevent the user from getting burned or cold.

In FIG. 1, the external appearance of the heating glove which concerns on this embodiment is shown.
In the figure, a indicates the left-handed heating glove seen from the back of the hand, and b shows the left-handed heating glove seen from the palm side. Note that the right-handed heating gloves have a symmetrical configuration with the left-handed heating gloves.
As shown in the drawing, the heating glove 1 has a general glove shape for watering work using synthetic rubber for the outer surface as a whole. However, the heating control unit 2 is attached to the back wrist part of the hand. In addition, the abdomen of each fingertip of five fingers, the middle abdomen of the second finger to the fifth finger (the abdomen of the node between the distal interphalangeal joint and the proximal interphalangeal joint), say by palm Metal cooling plates 3 with non-slip embossing are fixed to the outer surface of the glove at 11 locations on Venus Hill and Moon Hill. A power supply cable 4 extending from the wrist side end of the glove is connected to a body-mounted battery box (not shown).
[0011]
Here, the arrangement of the cooling plate 3 is an arrangement that assumes frozen tuna cutting and grinding operations, and the position of each cooling plate 3 is frozen when the operator holds the frozen tuna block during these operations. The tuna and the heating gloves 1 are in contact with each other.
Next, the layer structure of the heating glove 1 is shown in FIG.
As shown in the drawing, the heating glove 1 is connected by a metal flexible connecting member 25 between a heat insulating synthetic rubber outer surface 21 and a heat conductive synthetic rubber or other material lining 22. It has a multilayer structure in which a metal heat sink 23 is partially inserted. One surface of the thermo module 24 is fixed to the surface 21 of the heat sink 23 in a predetermined arrangement. In addition, a hole is provided in the outer surface 21 so that the other surface of the thermo module 24 is exposed from the outer surface 21, and the thermo module 24 is hermetically sealed with the lining 22 so as to cover the hole of the outer surface 21. The cooling plate 3 is fixed to the outer surface 21 and the thermo module 24. A temperature sensor 26 is fixed to a predetermined position on the back side of the heat radiating plate 23.
[0012]
Here, as shown in FIG. 3, the thermo module 24 includes N-type semiconductors 55 and P-type semiconductors 34 that are alternately arranged, and P − N − P − N. . . The conductors connected in this order are formed between the silicon substrates 31. Such a thermo module 24 functions as an electrothermal element by flowing an electric current, and heat transfer from one surface to the other surface occurs due to the Peltier effect generated at the junction between the N-type semiconductor 35 and the P-type semiconductor 34. . Further, the direction of heat transfer can be switched depending on the direction of current flow. In the present embodiment, the thermo module 24 is energized so as to heat the heat radiating plate 23 and cool the cooling plate 3, thereby heating the inside of the glove and cooling the outer cooling plate 3.
[0013]
Here, FIG. 4 shows the arrangement of the heat sink 23, the thermo module 24, and the temperature sensor 26 described above. In the figure, a shows the arrangement in the left hand heating glove 1 as seen from the back of the hand, and b shows the arrangement in the left hand heating glove 1 as seen from the palm side.
As shown in the figure, the above-described temperature sensor 26 is disposed at the center of the palm. Moreover, in the heating glove 1 of this embodiment, each finger | toe and palm are covered with the several heat sink 23 divided | segmented so that each movement might not be inhibited. Here, each heat sink 23 is sequentially connected to the adjacent heat sink 23 by a connecting member 25.

[0014]
Now, each heat radiating plate 23 plays a role of diffusion and heat dissipation of the heat conducted from the thermo module 24 to the entire inside of the glove, and a role of protection from the knife of the hand of the heating glove user during the cutting of the frozen material. Plays. Further, the connecting member 25 plays a role of heat conduction between the heat radiating plates 23 and protection from the blades in the gaps between the heat radiating plates 23. When the protective plate 40 is provided as shown in FIG. 4, the protective plate 40 also has the same function as the heat radiating plate 23.
[0015]
Next, FIG. 5 shows an electrical configuration of the heating glove 1.
As shown in the figure, the heating control unit 2 includes a power feed switch 201 connected in parallel to each thermo module 24 that turns on / off the supply of power from the battery box 51 to each thermo module 24, and a power feed control unit 202. The power supply control unit 202 is configured to control the operation of the power supply switch 201 according to the temperature detected by the temperature sensor 26. That is, the power supply control unit 202 controls the power supply switch 201 to supply power to the thermo module 24 when the temperature detected by the temperature sensor 26 is less than 36.5 degrees, and the temperature detected by the temperature sensor 26 is 36.5, for example. In the case where the temperature is equal to or higher than this, the power supply switch 201 is controlled to stop the power supply to the thermo module 24. And by such temperature control, a heating glove user's burn and low temperature burn are prevented.
[0016]
Note that the battery box 51 may output DC constant voltage power of commercial dry batteries connected in series or in parallel, for example.
The embodiment of the present invention has been described above.
According to the present embodiment, heating inside the glove and cooling the contact portion of the frozen material outside the glove can be efficiently performed by using the thermo module 24.
By the way, although the heating glove 1 was also provided with the protection function in the cutting work in the above, when the heating glove 1 is not applied to such a cutting work, for example, it is applied only to the transportation of frozen objects. If so, the layered structure of the heating glove 1 may be configured, for example, as shown in FIG. 2b.
[0017]
In the configuration shown in FIG. 2b, the heating glove 1 is provided with two metal film layers 61.62 between a synthetic rubber outer surface 21 and a lining 22 made of a synthetic rubber or other material having thermal conductivity, Between the two metal film layers 61.62, the heat insulating material 63 and the thermo module 24 in which each surface is in contact with the two metal film layers 61.62 are arranged. According to such a configuration, it is possible to obtain a heating glove 1 having lighter workability and capable of performing uniform heating inside the glove and uniform cooling outside the glove.
