The foot of the human body is so important that it is called a second heart because not only the acupuncture points to which all organs are connected, but also the capillaries and peripheral nerves are distributed.

In particular, the foot plays an important role in the blood circulation of the human body, if the blood circulation of the foot farthest away from the heart is not smoothly performed it may be the cause of development of various diseases or disorders.

For these reasons, people's interest in foot health, which has been relatively less interested, has increased, which is why we continue to improve the structure of the shoe that protects the foot by direct contact with the foot. The use of health aids such as foot baths or foot baths (hereinafter referred to as foot baths), foot pressure, foot massager to help release blood and circulation is increasing.

The foot bath is a device that submerges foot or hand in hot water and activates stagnant blood to improve the imbalance of body temperature.It promotes peripheral capillary blood flow of the foot, which is far from the heart, to remove waste and fresh blood. Since the development has been made in recent years because it helps to accept, and widely used bar, look at the "foot bath" of the domestic registration utility model No. 20-0244201 which one embodiment is disclosed as follows.

The footbath is a body (11) consisting of an upward open type enclosure having an insertion portion in the center, a heating plate with a built-in heating wire, and an adjustment box provided with a temperature control switch, a bubble generator operation switch, and a bubble generator at an upper end of one side; A heat collecting plate drawn in corresponding to an upper surface of the insertion unit; An upward open type enclosure having an inner space, the bottom plate consists of a tub 12 having a plurality of acupressure protrusions and bubble discharge holes.

That is, the water is contained in the inner space of the tub 12, and the heating wire built in the bottom portion is heated to heat the temperature of the water to an appropriate temperature, soaking feet in the water in the tub 12 and enjoying a foot bath, power is The advantage is that it can be easily used anywhere in the home.

However, in order to use the footbath, not only water is an essential element, but the bath or water must be moved to the bathroom or the water in order to contain the water in the bath 12, or the water must be used to pour water separately into the bath 12, There is an inconvenience to empty the water contained in the tub 12 after use again, there is a difficulty to repeatedly lift the heavy tub (12).

In addition, since the heater for heating the water is built in the bottom of the container, the upper and lower temperatures of the water contained in the bath are different from each other, and bacteria or viruses inhabiting the water are delivered to the user's feet as a result of unsanitary problems.

In addition, when using the foot bath to remove the foot from the foot bath due to other business, there is a cumbersome disadvantage that the water must be removed because the foot is in the water.

Thus, the function of the foot bath is maintained, but a foot heater was developed that does not use water. Looking at the "foot heater" of Korean Laid-Open Patent Publication No. 10-2000-0013578, an embodiment of which is described below.
