Description

[Detailed description of the invention] (Industrial application field) This invention uses thermoelectric elements such as thermomodules that are controlled at high and low temperatures by the Peltier effect.
For example, the present invention relates to a thermoelectric treatment device used for slimming and cosmetic treatment to remove abdominal fat, bruises, sprains, muscle fatigue, and other treatments.

(Prior Art) Conventionally, as the above-mentioned thermoelectric treatment device, there is a treatment device having the following structure, for example.

That is, the thermoelectric part of the thermoelectric treatment device fixes a metal plate to the front end of a long and narrow cylindrical case, presses the thermoelectric element to the inner surface of the case of this metal plate, and then presses a heat radiator to the inside of this metal plate to dissipate the heat. A hose connected to the cooling water passage of the container is formed by leading out to the rear end of the elongated cylindrical case. (For example, Japanese Utility Model Application No. 63-156615) According to this configuration, there is a problem that the shape of the thermoelectric part becomes vertically long and bulky, making it large.
When the metal plate part comes into contact with the treatment area, the rear end of the cylindrical case will extend upward.
It has the problem of poor weight balance and is difficult to operate.
Furthermore, since it cannot be fixed to a part of the human body with a simple aid such as a band, a person must hold the cylindrical case during treatment, which can be tiring. There are problems.

(Means for Solving the Problems) The purpose of this invention is to provide a water-cooled thermoelectric treatment device that can be easily operated and used for local treatment of acupuncture points, etc. by making the thermoelectric part smaller and more compact.

(Means for Solving the Problem) This invention includes a heat transfer plate whose outer surface is exposed to the outside at the bottom of one of the upper and lower modular boxes that engage with each other to form a flat box shape. A thermoelectric element that is controlled at high and low temperatures by the Peltier effect is adhesively fixed to the inner surface of the plate inside one of the module boxes, and a metal water jacket is tightly attached to the opposite side of the thermoelectric element to the plate. fixing the water jacket, and protruding the inlet port and outlet port of the water jacket to the side surface of the module box to form a thermoelectric section, and connecting the inlet port and outlet port of the water jacket of the thermoelectric section to the side surface of the module box. The thermoelectric treatment device is a thermoelectric treatment device in which the thermoelectric device is electrically connected to a water-cooled cooler of a control unit via a discharge line and a tank line of a hose, and the thermoelectric element is electrically connected to a control circuit element of a control unit via a wiring space of the hose. It is characterized by

(Effects of the invention) According to this invention, the thermoelectric element and the water jacket are housed in the upper and lower module boxes to form a flat box, and a hose is connected to the side of the flat box. The entire body has a flat shape, making it small and compact.
Since the hose is led out from the side of the thermoelectric unit box, the weight balance between the top and bottom of the flat box is maintained, making it easy to handle, and it can also be fixed to treatment areas such as acupuncture points using a band as an auxiliary tool. It has the effect of making it easier.
