Field of the Invention The present invention relates to a heating port for mountain climbing using a battery, and more particularly to a heating port for mountain climbing using a battery which is independent of weather and can boil contents in a liquid state such as cold water or coffee with self- will be.

Conventionally, a conventional port has been plugged into a power connection portion such as an outlet, and has been used to heat a liquid such as water or coffee contained in the port using electricity.

These existing ports are used as essential household appliances required by users as they keep the liquid state of water or coffee by keeping them warm. Especially, in the case of coffee, since the port for coffee has been released, users are using it a lot.

However, since such conventional ports can be supplied with electric power through an electrical connection device (such as an outlet and a plug and the like), there is a problem that it can not be used for portable purposes.

If the port is to be carried, it is inconvenient to use an electric connection device (socket, plug, plug and the like), so that it is inconvenient to carry a heating device for replacing it.

1, a conventional burner for heating the contents (coffee, water, and other liquid substances) contained in the port 100 when the port 100 needs to be carried 300) is also required to be carried together, so that the amount of items to be carried is inevitably increased, and the problem of portability is still difficult.

In the meantime, referring to FIG. 2, a description of a counter 200 capable of replacing an existing port in the absence of a conventional port is shown in FIG. 2. The contents (coffee, water, and other liquid substances The burner 300 must be carried together, so that it still can not be carried easily and has a structural problem.

Of course, portable port products that enhance portability due to port limitations of such ports are also being marketed. However, most portable port products use solar heat as a heat source.

However, while portable ports can use solar heat as a heat source, solar heat can vary with weather and climate, revealing the limitations of not being able to utilize solar heat, especially on cloudy or rainy days.

Due to the limitations of the use of solar heat, there are some products that use the detachment method of the burner to the port for the portability of the port. However, even if the burner is combined with the port, the overall size of the port is bigger, It does not reach the level.

In addition to the port technology described above, port products using various technologies are being marketed, but they do not satisfy portability. Also, since the ports are not cooled quickly after they are heated after they are heated, Electrical and mechanical faults of the ports are also occurring.

As described above, existing ports are limited in terms of easiness of portability and simplicity, and in the case of a port using electric power as a heat source, electrical connection devices must be accompanied, so that it is inevitable to carry the port practically.

Of course, the simplicity of portability can be satisfied when a solar-powered port is used as a heat source, but the utilization of the solar heat is different depending on the weather and the climate.

On the other hand, techniques for port can be referred to through the patent documents disclosed in the following prior art documents.

It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory and are intended to provide further explanation of the invention as claimed. And it should be interpreted based on the technical ideas throughout the specification taking into consideration that various modifications are made.

In addition, the present invention should not be construed as being limited to the embodiments described below, but should be construed as a scope of scope including an extended scope interpreted based on the technical content described in the specification.

As shown in FIGS. 3 and 4, the heating port for a mountain climbing using a battery according to the present invention includes a first member 20 for supplying / And a third member (40) formed between the spaces of the first and second members for interrupting the energization of electricity for generating heat in the first member space (10). &Lt; / RTI >

The first member 20 has a configuration for taking into consideration the use of heating the contents (coffee, cold water, and other liquid state materials) contained in the cup C together with a space for loading or unloading the cup 3, a case-shaped housing 21 having a diameter gradually progressively increased toward the upper portion, and a case-like housing 21 provided along the inner circumference of the housing 21, And a heater 22 for heating the object (coffee, cold water, or other liquid material).

At this time, it is preferable that the heater 22 uses a nichrome-based metal heating element. This is because the container port 10 is utilized for portable use, and therefore, it is difficult to oxidize even in a high temperature state in the air in consideration of environmental characteristics used in places such as mountain climbing and outdoor travel, and is excellent in heat resistance and corrosion resistance.

The second member 30 includes a battery 32 which is disposed below the first member 20 and serves as a heat source for heating the heater 22 of the first member 20, And a receiving portion 31 for receiving the liquid.

The electric wire terminals 33 and 33a may be formed at the end of the electric wire 60 connected to the battery 32. The electric wire terminals 33 and 33a may be connected to the housing 21, And the position of the cover support plate 50, which is located between the cover support plate 50 and the cover support plate 50.

The third member 30 is disposed between the first and second members 20 and 30. The third member 30 is preferably a conductive intermittent portion 41 and includes a bimetal 42 ), A fixed holder 43, switching units 44 and 44a, and springs 45 and 45a.

The bimetal 42 is formed in such a manner that the bimetal 42 protrudes upward from the floor at the center of the bottom space of the housing 21 and the fixed holder 43 Is located at the bottom of the floor space in the housing 21. [

At this time, the floor bottom, which is a place for holding the cup (C) in the housing 10, and the upper surfaces of the fixed holder 43 are mutually interlocked by a stepped structure.

The switching units 44 and 44a are formed to extend from the bimetal 42 toward the outside in the horizontal direction along the lower surface of the bimetal 42 so that the cups C are inserted into the housing 21 The bimetal 42 including the fixed holder 43 is pushed toward the vertical downward direction due to the weight of the contents contained in the cup C including the load of the cup C, The battery 32 is charged or consumes the electric power of the already charged battery 30 and generates heat from the heater 22 while being contacted with the electric wire terminals 33 and 33a located at the lower portion while being pushed in the vertical downward direction .

At this time, the bimetal 42 may not be energized even when the wire terminals 33 and 33a are in contact with the switching units 44 and 44a. This is because the bimetal 42 can be reacted The predetermined threshold value is set so that the temperature of the contents (coffee, cold water, or other liquid material in the liquid state) contained in the cup C is detected when the temperature reaches a specific temperature, do.

On the other hand, when the cup C is taken out of the housing 10 when the contents contained in the cup C reach a desired temperature, the fixed holder 43 including the bimetal 42 springs upward due to the elastic force, The switching parts 44 and 44a formed at the lower outer periphery of the electric wire 42 are also spaced apart from the electric wire terminals 33 and 33a so as to be able to automatically cut off the energized state.

Of course, at this time, the fixed holder 43 including the bimetal 42 and the switching parts 44 and 44a can be bounced by the elasticity of the springs 45 and 45a to be described later.

The springs 45 and 45a are fixedly coupled to a bottom portion of a stepped (not shown) structure in which one end of the springs 45 and 45a is fixed at both ends of the fixed holder 43 and the other end is fixed between the housing 21 and the accommodating portion 31 And is fixedly coupled to the upper end portion of the cover supporting plate 50 to be coupled.

Therefore, when the cup C is placed inside the housing 21, the bimetal 42 supporting the bottom bottom portion of the cup C due to the weight of the contents contained in the cup C including the cup C, The spring 45 and the spring 45a are moved in a horizontal direction from the outer peripheral edge of the lower end of the bimetal 42 to the outer side of the bimetal 42 The switching units 44 and 44a are turned on while being in contact with the electric wire terminals 33 and 33a located at the lower part thereof so that the heater 22 is heated via the electric power of the battery 32, The outer side of the cup C can be heated to boil the contents contained in the cup C.

At this time, if the temperature of the contents held in the cup C reaches the predetermined threshold value, the bimetal 42 is kept in the energized state due to the contact holding between the switching units 44 and 44a and the electric wire terminals 33 and 33a And the power supply from the battery 32 is automatically shut off in a manner of interrupting the current, so that the remaining charge power of the battery 32 can be saved.

When the cup C is pulled out of the housing 21 as the temperature of the contents contained in the cup C reaches the preset threshold value, the bimetal 42 is pulled by the elastic force of the contracted springs 45, The switching section 44 and the switching section 44 are automatically returned to the original position by the elastic return force and the switching sections 44 and 44a are separated from the electric wire terminals 33 and 33a, State so that the remaining charge power of the battery 32 can be saved.

As described above, the container port of the present invention utilizes the charging power of the battery constructed in itself without requiring an electrical connection device for using electricity as a heat source, so that it can be utilized effectively in leisure activities such as traveling and mountain climbing. It is possible to carry only the container port without the necessity of providing the heat source generating means of the present invention. Therefore, it is possible to provide ease of portability and simplicity, and the advantage of using the heat source regardless of weather or climate without using a heat source such as solar heat In addition, when the container port is used outdoors, the charge power of the battery is used as a heat source, so that a disaster such as a fire caused by the incendiary fire can be prevented.

Particularly, in mountain climbing activities, it is possible to boil the cold water using the container port which is carried when the mountain climber loses the mountain or when the distress is caused by the injury, so that the dehydration and the hypothermia, The use of the battery charging power as a heat source has the advantage of contributing to the environment by eliminating the one-time heat source, and the additional consumption cost during the use period of the container port is small.

The heating port according to the present invention may also be configured as a second embodiment with reference to FIG. 3, as shown in FIG. 5, wherein the heater (not shown) formed along the inner circumference of the housing 21 22, a heating catalytic portion 70 may be further provided. The heating catalytic portion 70 is configured such that one surface thereof is bonded to the rear surface of the heater 22.

The heating catalyst part 70 is a kind of resistance heating element corresponding to a non-metallic heating element, preferably a silicon carbide heating element. The composition of the heating catalyst part 70 is silicon carbide (SiC) (Fe), calcium oxide (CaO), magnesium oxide (MgO), silicon (Si), silicon dioxide (SiO2) and carbon (C).

Since the heater 22 uses a metallic heating element of nichrome, the heating speed and the heating temperature range may be limited. To this end, the heating catalyst part 70 formed on the back surface of the heater 22 ) Can use the silicon carbide heating element, which is a non-metallic heating element, to accelerate the heating and heating of the heater 22 using the nichrome-based metal heating element, and to boil the water at 100 ° C or higher The sterilizing power can be provided.

Since the heating catalytic portion 70 has a feature of promoting the heating temperature of the nichrome-based metal heating element in a high degree of melting point, when the superheat elimination occurs at a slow speed, mechanical defects such as breakage due to rapid aging There is a disadvantage that a long life can not be guaranteed.

Accordingly, since the heat dissipating portion of the heat dissipating inducing portion (not shown) described later is formed for the purpose of promptly overcoming the overheating of the heating catalyst portion 70, the heating catalyst portion 70 is heated by the heating catalyst of the heater 22, It is possible to solve the mechanical defect of the heating catalytic portion 70 and to prolong the service life for a long period of time.

5, the heat dissipating unit 80 may include a heat dissipating unit 80 and a heat dissipating unit 90. The heat dissipating unit 80 may include a heating catalyst unit 70, So that the heat generated from the heating catalyst unit 70 can be dissipated.

The discharge unit 90 is coupled to the rear surface of the heat dissipation unit 80 in such a manner that one surface of the discharge unit 90 is in contact with the rear surface of the heat dissipation unit 80. From the position corresponding to the other surface of the discharge unit 90 to the outside of the housing 21, A plurality of exhaust holes 21a are formed along the outer periphery of the exhaust pipe 21.

The exhaust holes 21a discharge the heat discharged through the discharge portion 90 to the outside so as to overheat the heat generated by the heater 22 and the heating catalytic portion 70, , It is expected that the effect of extending the life of the port product can be expected.

The heat dissipation unit 80 and the emission unit 90 constituting the heat dissipation inducing unit may be formed in the housing 21 of the first member 20, 30 of the first embodiment.

That is, the structure of the heat dissipation inducing unit can be configured in the accommodating unit 31 because the accommodating unit 31 is provided with the battery 32 that is overheated. Since the battery is a rechargeable battery, the battery can be overheated even when being charged, so that the heat dissipation induction unit is formed in the storage unit 31, so that the overheat generated in the battery can be dissipated to the outside to overheat the container port 10.

This heat dissipation inducing portion is formed not only by the overheat generated by the heating catalyst portion 70 including the heater 22 formed in the housing 21 of the first member 20, There is an advantage that the life of the container port can be prolonged as the superheat generated by the battery 31 constructed in the container 31 is also radiated to the outside to overheat the inside of the container port 10.

That is, at this time, in the heat dissipation inducing portion, for example, the overheat including the heat generated by the heating catalytic portion 70 including the heater 22 is transmitted to the heat dissipating portion 80 And the overheat including the heat transferred to the heat dissipating unit 80 can be quickly transmitted through the heat dissipating unit 90.

The overheat including the heat transferred to the discharge portion 90 is cooled through the cooling heat medium in the zigzag refrigerant line 91 installed in the discharge portion 90, The heat dispersed through the plurality of exhaust holes 21a formed through the outer periphery of the housing 21 from the position corresponding to the other surface of the discharge portion 90 to the outer side of the housing 21, It becomes possible to suppress the overheating of the container port 10 as it is discharged.

As a result, even after the container port 10 is used for cooling, the temperature of the container port 10 is rapidly lowered as the superheated heat including the heat remaining in the container port 10 is quickly resolved For this reason, the mechanical defects of the container port 10 can be solved and the effect of extending the life of the container port 10 can be expected.
