An operating state of the air mattress 1 having the heater unit according to the embodiment of the present invention having the above configuration will be described.

The first cell member 22 and the second cell member 32 are swollen in a set state by the pneumatic pressure supplied to the air mattress 1 having the heater unit according to an embodiment of the present invention.

When the user is lying down in the above state, the second cell member 32 spreads the pressure while widening from side to side.

Accordingly, by using a plurality of second cell members 32 having a smaller volume than the first cell, the weight of the user can be uniformly supported by a wider area, thereby providing a more comfortable feeling.

That is, the second cell member 32 alternates between the first cell member 22 and the second cell member 32 because the gap between the cells is narrower than that of the first cell member 22. The support is made to be more natural, and the user has a more comfortable use than the shift is made by a conventional single cell.

This is because the distance between the second cell member 32 and the adjacent second cell member 32 is narrower than that of the first cell member 22, and the second cell member 32 is connected to the first cell member ( 22) because the second cell member 32 is relatively free to move due to the pressure change due to the rotatable state.

In addition, the first cell member 22 may be alternately supported in a variety of ways, including alternately supporting adjacent cells, several consecutive cells are divided into groups, and alternately supporting each other. Of course.

The second cell member 32 provided above the first cell member 22 is operated in conjunction with the first cell member 22 when one side is installed in communication with the first cell member 22.

However, when the first cell member 22 and the second cell member 32 are partitioned from each other, the second cell member 32 also alternately supports adjacent cells, and several consecutive cells Different types of shift stimulation methods may be applied, including alternately supporting each group.

The auxiliary cushion portion 30 as described above is uniform in the pressure distribution of the auxiliary cushion portion 30 for supporting the user's body because the degree of deformation of the second cell member 32 is different according to the bending of the body. In addition, the pressure is distributed in the secondary cushion portion 30 and the main cushion portion 20 in the primary and secondary portions to provide a more comfortable feeling.

The heater unit 10 is heated by the control unit to heat and heat the air in the main cushion unit 20, the auxiliary cushion unit 30, and the supply cell 70. The heater unit 10 used in the manner provides a safer use environment because electromagnetic waves are not directly transmitted to the user.

Then, the air supplied to the first cell member 22 and the second cell member 32 through the supply cell 70 may be exhausted to the outside in a heated state, and returned to the control unit 40 again. In addition, it may be supplied to the other first cell member 22 and the second cell member 32.

That is, when the main cushion portion 20 and the auxiliary cushion portion 30 alternately expand and contract and alternately support levitation, the heater unit 10 is not continuously operated, and only the intermittent operation is performed. The temperature of the air supplied to the cushion unit 20 and the auxiliary cushion unit 30 can be increased.

On the other hand, it is also another embodiment of the present invention to apply or install the electromagnetic wave blocking material on the inner surface of the heater cover 60 in order to block the electromagnetic waves generated in the heater unit 10.

Although the present invention has been described with reference to the embodiments shown in the drawings, this is merely exemplary, and those skilled in the art to which the art belongs can make various modifications and other equivalent embodiments therefrom. Will understand.

In addition, various changes occur in the technical concept of installing the heater unit 10 on the lower side of the air mattress and the technical concept of the main cushion unit 20 and the auxiliary cushion unit 30 in communication with the main cushion unit 20. It is possible.

Therefore, the true technical protection scope of the present invention will be defined by the claims below.

As described above, the air mattress having the heater unit according to the present invention, unlike the conventional invention, blocks the transmission of electromagnetic waves generated from the heater unit to the user by installing the heater unit below the main cushion unit, and the main cushion unit as a whole. To be heated uniformly.

In addition, the present invention includes a plurality of second cell members on the upper side of the main cushion portion, the weight of the user is more uniformly distributed by the surface area of the cells constituting the air mattress and the spacing between the cells more uniformly, so that the load is applied to only one side of the body. Concentration can be prevented from causing bedsores.
