Description

Cup warmer {CUP WARMER}

The present invention relates to a cup warmer, and more particularly, it has a concise and simple structure, can improve portability, usability and storage by minimizing volume and weight, and can be easily changed in shape so that it can be used interchangeably for various purposes. It relates to a cup warmer that not only can be used, but also has improved adhesion properties to effectively transmit heat.

In general, beverages that are consumed in a hot state, such as coffee and green tea, become cold after a certain period of time has elapsed, so there is a disadvantage in that their inherent taste is lost.

Accordingly, in recent years, a cup warmer for keeping a beverage in a warm state for a long time has been developed and used.

For example, as a cup warmer, a multifunctional cup warmer as shown in Korean Patent Registration No. 10-1512467 has been proposed.

The multi-function cup warmer is an AC/DC converter that converts high-pressure commercial AC power to low-voltage DC as shown in FIG. 1 ; A terminal connected to the AC/DC converter, a heating unit electrically connected to the terminal and having a heating switch controlled by the following control unit, an input unit for receiving an operation button signal of the heating unit from the outside (user) and transmitting it to the following control unit , a main body including a control unit for turning on the heating switch until a predetermined time elapses when the operation button signal is an on signal or an off signal is input.

The above-described conventional multi-functional cup warmer can maintain a warm state by the heat applied from the heating unit when the teacup is placed, but has several limitations as follows.

The conventional multifunctional cup warmer has a complex structure and many components, so it takes a lot of time to manufacture and increases the manufacturing cost.

In addition, the conventional multi-function cup warmer is bulky and relatively heavy, so it is inconvenient to carry, use, and store.

In addition, the conventional multifunctional cup warmer has a disadvantage in that it is impossible to change the shape, so it cannot perform other functions other than the function of warming the teacup, thereby lacking compatibility.

In addition, since the conventional multi-functional cup warmer is a method of heating the bottom of the teacup, if the teacup has a bend, it does not adhere to the bottom surface and heat is not transmitted, so there is a disadvantage that the function of the warmer cannot be performed properly.

A power supply line 26 is connected between the connector 22 and the heating wire 21 . The power supply wire 26 is configured by arranging conductive wires having a lower electrical resistance value than the heating wire 21 so that power can be easily supplied to the heating wire without being heated.

The heating means restraining part 6 is not particularly limited in form or structure as long as it can be fixed by arranging the heating wires 25, but in this embodiment, as shown in FIG. 9b, the band body of the cup warmer body 1 It is composed of a bar flat body 61 that is padded on 11, and the hot wire 25 by a sewing wire 62 formed by a fiber thread sewn in the transverse (or longitudinal) direction to the bar flat body 61. It has a structure in which an insertion pleat having an insertion hole 63 for accommodation is formed.

Hereinafter, the operation of the cup warmer according to the fourth embodiment of the present invention will be briefly described.

First, when explaining the manufacturing process of the cup warmer according to the fourth embodiment, a fan-shaped faceted body is manufactured by cutting the same material as the fabric to be used as the cup warmer body, and a male Velcro fastener 32 is attached to the inner side edge of the fan-shaped facet body. Install it on the part and install the female Velcro fastener (not shown) on the outside. In this state, after cutting and attaching a bar-shaped planar body 61 such as fabric paper to the sector-shaped planar body, the proximal part is sewn and bound by a sewing machine, but at regular intervals along the lateral direction for insertion of the heating means (2). A sewing line 62 is formed so that a plurality of insertion wrinkles having an insertion hole 63 are formed. In this state, both ends of the insertion wrinkle are cut to form an opening communicating with the insertion hole 63 inside, and a hot wire is inserted into the insertion hole 63 through this opening to form a zigzag structure, and the production is completed. .

As shown in Fig. 9a, the cup warmer according to the fourth embodiment has a binding means composed of female and male Velcro fasteners in a state in which the cup warmer body 1 is wound in close contact with the surface of the cup, and is positioned on the circumferential surface of the cup. (3) is attached to each other.

In this state, when the connector 22 of the heating means 2 is connected to the power supply unit, the heat emitted while the heating wire is heated by electrical resistance is applied to the surface of the cup, thereby performing a warming effect to maintain the temperature of the hot beverage. can do.

And, since the cup warmer according to the fourth embodiment can be separated from the cup warmer body 1 by pulling out the heating means 2 from the insertion hole 63, it can be separated if necessary and used interchangeably as a heating tool for other purposes. there are advantages to

What has been described above is only one embodiment for implementing the cup warmer according to the present invention, and the present invention is not limited to the above embodiment, and does not depart from the gist of the present invention as claimed in the claims below. It will be said that the technical idea of the present invention exists to the extent that various modifications can be made by anyone with ordinary knowledge in the field to which the invention pertains within the scope not included.
