Technical Field

[0001] The present invention relates to a portable rechargeable heating stove. More specifically, a heating device is disposed inside a circular pipe having good thermal conductivity to transfer heat to the surface of a cylinder so that a warm body temperature can be maintained outdoors at a camping site or at home in cold seasons. The present invention relates to a portable rechargeable heating stove.

Background Art

[0002] As a heat retention means that can be used while being carried personally on a cold day, a disposable hand warmer can be mentioned. Although a disposable hand warmer has the advantage of being easy to use, it is inevitably discarded after use, so there is a burden on the environment. Since a disposable hand warmer only functions to warm the hands, there are limitations in its usage.

[0003] Although heating means for warming the body by electricity are provided in various forms, since the heating element consumes a large amount of power, it is generally handled as a heating appliance and is designed to operate by receiving power supply through a wire.

[0004] Conventionally, many proposals have been made for portable heating appliances that can be used at a camping site or the like.

[0005] For example, the portable steam heating device disclosed in Korean Registered Patent No. 10-0700313 is an example. This uses a portable gas burner as a heat source and is for warming a bed.

[0006] Also, the portable heater disclosed in Korean Registered Utility Model No. 20-0216403 also uses gas as a heat source instead of electricity.

[0007] In this way, various proposals have been made for portable heating appliances, and the present invention is proposed as part of them. In particular, the present invention aims to propose a solution for utilizing the electrical energy provided by charging in various ways.

[0019] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings attached to the specification. The embodiments of the present invention will be described with reference to FIGS. 1 to 5 simultaneously.

[0020] The portable rechargeable heating stove (hereinafter referred to as "heating stove") according to an embodiment of the present invention has a heating function as a basic function, and in addition, can further have a lighting function. As shown in FIGS. 1 to 2, the heating stove according to the present invention can be formed by combining two unit heating stoves 1 and 1' having the same configuration into one body. And, as shown in FIG. 2, it can also be configured to be separated from each other and used separately. The two unit heating stoves 1 and 1' may be coupled to each other by a screw type or may be coupled to each other by a magnet.

[0021] According to such a configuration, two people can each use the unit heating stoves 1 and 1'. Needless to say, as shown in FIG. 3, it can also be used as a single component. Since the two unit heating stoves 1 and 1' have the same configuration as each other, only one of them will be described as a representative example hereinafter.

[0022] As shown in FIGS. 3 to 4, the heating stove 1 basically includes a heating cylinder 10, a heating element disposed on one side of the heating cylinder 10, for example, lighting lamps 11 and 13, and a power supply unit 20 that supplies power to the lighting lamps 11 and 13. Any means capable of converting electrical energy into thermal energy can be used as the heating element. However, in this embodiment, the use of the lighting lamps 11 and 13 is exemplified. Therefore, the heating element can be a film-shaped surface heating element. In some cases, two or more heating elements can be used in combination. When a surface heating element is used, it may be closely attached to the inner surface of the heating cylinder 10 in a round-wound state.

[0023] Hereinafter, the lighting lamps 11 and 13 will be described as representative examples of the heating element.

[0024] The lighting lamps 11 and 13 are components that emit light when supplied with power. As the lighting lamps 11 and 13, a halogen lamp can be preferably used. However, in some cases, an LED lamp may be used, or a near-infrared lamp may be used. When the lighting lamp is an LED lamp, it may be arranged in a cylindrical shape inside the heating cylinder 10 so that heat can be transmitted to the heating cylinder 10 to the maximum extent. Also, when the lighting lamp is an LED lamp, it may include a light-emitting circuit and a substrate 13 on which the LED element 11 is mounted. And it may further include a control unit described later. The control unit may include an interlock switch so that discharge cannot occur during charging.

[0025] A reflecting mirror 12 having a parabolic curved surface may be provided inside one side of the heating cylinder 10 due to the straight-line propagation of the light emitted from the lighting lamps 11 and 13. Although not shown, a transparent lens may be disposed in front of the lighting lamps 11 and 13. The lens may be flat glass or may be curved glass capable of refracting light.

[0026] A chromium reflector may be disposed on the inner surface of the heating cylinder 10 so that the light of the lamp can be reflected. In addition, a heat insulation device or an aluminum holder for protecting the internal circuit or device from the heat generated inside the heating cylinder 10 may be disposed.

[0027] The heating cylinder 10 is a means for accommodating the heat generated from the lighting lamps 11 and 13 and dissipating it to the outside. The heating cylinder 10 may be cylindrical and may be made of an aluminum alloy with a high heat transfer rate. Heat dissipation fins (not shown) may be provided on the whole or a part of the outer surface of the heating cylinder 10 so that heat can be dissipated to the outside. The heat dissipation fins may be provided in various shapes. For example, they may be provided in a serrated shape.

[0028] The heating cylinder 10 may be bellows-type and may be configured to be adjustable in size.

[0029] On the other side of the heating cylinder 10, a shielding cap 30 is disposed so as to be removable. The shielding cap 30 is disposed at the opening of the heating cylinder 10 from which light comes out. The shielding cap 30 has a male screw portion 31 so that it can be coupled to the heating cylinder by a screw type. The shielding cap 30 blocks all or part of the light and absorbs the heat generated from the lighting lamps 11 and 13. When the power is turned on with the shielding cap 30 fixed to the heating cylinder 10, heat is generated inside the heating cylinder 10, and this heat is transmitted to the outside in the form of radiation or conduction through the heating cylinder 10 and the shielding cap 30. Therefore, it can perform the function of a heater.

[0030] A power supply unit 20 is disposed on one side of the heating cylinder 10, and the power supply unit 20 may be provided with a rechargeable battery 23. A charging terminal may be disposed on the power supply unit 20.

[0031] In some cases, power can be supplied from a power bank or a car cigarette socket, and a rechargeable battery pack can be disposed inside the heating cylinder 10 to be used as a portable charging type.

[0032] Inside the battery pack, a battery protection device with a temperature sensor is provided so that the power supply of the battery can be cut off when the temperature of the battery rises. Note that the battery pack may be configured to be removable inside the heating cylinder 10, and when used in a power bank or at home, it may be removed from the heating cylinder 10 to reduce the weight.

[0033] And charging means 40 may be provided so that it can be charged using a household power supply or a vehicle power supply. FIG. 5 shows charging means in which a cigarette socket connector 41 for connecting to a vehicle cigarette socket is disposed on one side and a connection terminal 42 is disposed on the other side.

[0034] Although not shown, a slip ring may be adopted for the cable that receives power supply from the power bank to prevent the twisting of the cable.

[0035] The power supply unit 20 may be disposed integrally with the lighting lamps 11 and 13. On the back surface of the power supply unit 20, a power button 21 and an adjustment button 22 capable of adjusting the light quantity or temperature may be provided. When used at home, the power supply unit may be configured to be able to utilize an AC 220V power supply by using an adapter.

[0036] The shielding cap 30 may be provided with a predetermined connecting means 32 so that the two lanterns 1 and 1' can be linearly connected in the manner shown in FIG. 1. As this connecting means 32, a screw may be adopted, a magnet may be adopted, or a one-touch coupling tool may be adopted.

[0037] On the one hand, when fixing the shielding cap 30 to the heating cylinder 10, the heat emitted from the lighting lamps 11 and 13 can be used as a heating means such as a portable hand warmer. When the shielding cap 30 is removed from the heating cylinder 10, it can be used as a lighting means. For the prevention of loss, the shielding cap 30 and the heating cylinder 10 may be connected by a chain or a wire. In some cases, the shielding cap 30 may be connected to the end of the heating cylinder 10 by a hinge so that it can be easily opened and closed.

[0038] According to another embodiment of the present invention, on the other side of the heating cylinder 10, a mesh-shaped protective net 33 for protecting the lighting lamps 11 and 13 may be provided. This is because there is a risk that foreign objects may flow into the inside of the heating cylinder and cause ignition, and there is also a risk of damaging the lighting lamps 11 and 13, so it is necessary to prevent this. The protective net 33 is disposed between the lighting lamps 11 and 13 and the shielding cap 30.

[0039] According to still another feature of the present invention, a temperature sensor may be further disposed in the heating cylinder 10. And when a temperature equal to or higher than a set value is detected by the temperature sensor, a control unit for cutting off the power supply to the lighting lamps 11 and 13 may be further provided. As described above, this control unit may be disposed on the substrate 13 of the lighting lamp, or may be provided on a separate substrate. As a control method, a control method using a temperature sensor and a control method of a printed circuit board (PCB) (touch method) and a pulse width modulation (PWM) method can be used.

[0040] According to still another feature of the present invention, a blower fan (not shown) may be further disposed inside the heating cylinder 10 or in the shielding cap 30 so that the air inside the heating cylinder 10 can be blown to the outside. The shielding cap 10 may be provided with exhaust holes so that air can be discharged. This is for forcibly discharging the hot air to the outside through the exhaust holes.

[0041] The unexplanation drawing reference numerals 10’, 20’, and 30’ respectively indicate a heating cylinder, a power supply unit, and a shielding cap, and are the same as those of 10, 20, and 30 described above.

[0042] The portable rechargeable heating stove of the present invention has a heating bulb or a heating film disposed inside a cylinder with good thermal conductivity, and transfers the heat generated inside to the surface, so that it can be held against the body in the wild camping ground or at home in cold seasons, or held against the body inside a futon or a sleeping bag, and can be used as an auxiliary means for a stove that can maintain body temperature.

[0043] In addition, when fishing with the shielding cap 30 of the heating cylinder 10 opened, it can be used as a fish attracting lamp, and the effect of warming the whole inside the sleeping bag can be exerted. And the shielding cap 30 can also be utilized as a pedestal for the heating cylinder 10, and the hot air of the halogen lamp coming out of the heating cylinder 10 can also be used for hot pack heat therapy for relieving joint pain and muscle pain. In some cases, for the purpose of preventing skin burns, a silicon cover can be overlapped on the surface of the heating cylinder 10 or a coating can be applied.

[0044] The portable rechargeable heating stove of the present invention can be utilized for such a variety of applications in this way.

[0045] What has been described above is only several examples based on the technical idea of the present invention. Those skilled in the art should be able to make various modifications and implementations by utilizing the exemplified matters within the scope not departing from the technical idea scope of the present invention represented through the claims. For example, all the above-described embodiments can be freely combined and implemented by those skilled in the art, and regardless of the combination, it should be interpreted as being included within the scope of the rights of the present invention.
