By the way, in the conventional electric steamer, the housing 10 is to be formed in a single layer structure of a relatively thin thickness synthetic resin member, the deformation and / or damage due to external impact can be easily generated. Due to this, the service life of the electric steamer can be shortened.

In addition, continuous deformation with the human body may be difficult and / or insufficient when deformation of the housing 10 occurs, and thus the poultice effect may be insufficient.

In addition, the housing 10 has a planar and / or outer convex shape on the outer surface thereof, so that the contact area with the protruding portion such as the joint portion of the human body is small and the poultice effect of the joint portion may be insufficient.

In addition, the housing 10 has a problem that it is difficult to grip the surface due to the smooth surface, it can slip off the hand during handling, and the crack and / or breakage of the housing 10 is caused by the impact during the fall have.

In addition, since the housing 10 has a single layer structure, heat loss is relatively large, and thus the number of charges and power consumption may be increased. In addition, frequent charging may cause inconvenience to the user, such as interrupting the continuous poultice.

Therefore, an object of the present invention is to provide an electric steamer which can suppress deformation and damage of the appearance (housing) and can prolong the service life.

In addition, the housing assembly 110 may be configured to include an outer housing 131 forming an appearance and an inner housing 132 disposed in the outer housing 131 and forming an accommodation space therein. have.

The housing assembly 110 may be configured to include, for example, a first housing assembly 111 and a second housing assembly 112 coupled to face to each other.

The housing assembly 110 may be, for example, configured to be coupled to face to face each other along the vertical direction.

For example, the first housing assembly 111 may be disposed above and the second housing assembly 112 may be disposed below the first housing assembly 111.

The first housing assembly 111 and the second housing assembly 112 may be configured to include an outer housing 131 and an inner housing 132, respectively.

The housing assembly 110 may further include an intermediate housing 133 disposed between the outer housing 131 and the inner housing 132.

The intermediate housing 133 may be spaced apart from the outer housing 131 and the inner housing 132, respectively.

The outer housing 131 may be formed of, for example, a thermosetting resin (more specifically, for example, bakelite).

The inner housing 132 and / or the intermediate housing 133 may be formed of, for example, fiber glass.

A heat accumulator 210 may be provided inside the inner housing 132.

As illustrated in FIG. 5, the heat storage unit 210 may include a heat generation unit 211 that generates heat when power is applied, and a heat storage unit 221 formed around the heat generation unit 211. .

The heat storage unit 221 may be configured in a circle (ellipse) half shape to surround the zig-zag-shaped heat generating unit 211.

A heat insulating material 231 may be provided around the heat storage unit 221. As a result, heat loss of the heat accumulator 210 can be suppressed, so that the heat generation (durable) time of the heat accumulator 210 can be extended.

Here, the heat accumulator 210 may be configured to reach a proper temperature (for example, about 65 ℃) by about 3 to 5 minutes of charging.

The insulation 231 may be implemented with, for example, ceramic fibers.

The insulation 231 may be filled in the interior of the intermediate housing 133 and / or the interior of the inner housing 132, respectively.

In the electric steam generator of this embodiment, the housing assembly 110 is composed of a double (external housing 131 and the inner housing 132), or triple (external housing 131, the intermediate housing 133 and the inner housing) (132)), and the heat insulating material 231 is provided therein, so that the exothermic (heating) effect can be maintained for a relatively long time during one charge (5 minutes). For example, when the housing assembly 110 is composed of triple, it can be confirmed that the heating (heating) effect can be maintained for 5 hours indoors when charged once (5 minutes). In addition, when the present electric steamer is used together with a warming means (for example, bedding, etc.), the width of the exothermic (heating) effect is remarkably extended, thereby improving user convenience.

The housing assembly 110 may include a connector 171 to supply power to the heat storage 210.

The connector 171 may be composed of two or more.

For example, since the power cable 175 may be connected to the relatively accessible connector 171 in the state in which the electric steamer of the present embodiment is attached to the human body, charging may be facilitated.

The heat accumulator 210 may be configured to include a power supply control unit 181 that cuts off the power supply when a preset temperature (eg, about 65 ° C.) is reached.

The power supply control unit 181 may be implemented by, for example, bimetal.

The power supply control unit 181 may be provided at one side of the heat storage 210.

The display unit 191 may be configured to include, for example, a lamp 193 related to visual information. For example, the lamp 193 may be configured to be turned on or blinking for a preset time (for example, 10 seconds) upon completion of charging.

The display unit 191 may be configured to include, for example, a speaker 194 related to auditory information. For example, the speaker 194 may emit a sound for a preset time (for example, 10 seconds) when the charging is completed to indicate the charging completion. Here, the sound may be variously configured, for example, a bird sound, a beep sound (beep sound), a ringtone, a music sound, and the like.

In the present exemplary embodiment, the display unit 191 is configured to include both the lamp 193 and the speaker 194.

According to this configuration, the power supply control unit 181 stops supplying power when the heat accumulator 210 reaches a preset temperature, and the display unit 191 supplies power by the power supply control unit 181. When interrupted (blocked) it can be displayed externally with visual and / or auditory information.
