Benefits of technology

[0017]An object of the present invention is to provide a heating device for a hot water mat that can prevent shock noise due to a floatable check valve hitting against other parts while horizontally moving.
[0018]Another object of the present invention is to provide a heating device for a hot water mat in which when liquid decreases in a heating module, a hole is opened by a check valve and liquid is smoothly supplied by allowing the check valve to be freely moved up and down by buoyancy and its own weight to open / close so that the hole is prevented from not being opened.
[0019]A further object of the present invention is to provide a heating device for a hot water mat in which a heater and a sensor unit for heating liquid are easily and stably combined with a heater housing into a module.

Problems solved by technology

However, electric wires are disposed in the electric blanket or the electric mat, so there is always a danger of an electric shock accident, harmful electronic waves are generated by their electric characteristics, and the harmful electronic waves are known as being harmful to a human body.
In the “Hot water supply apparatus having check valve with improved molding property” disclosed in Korean Utility Model No. 20-0474868, a check valve for opening / closing a hole using buoyancy of liquid is horizontally moved, so it continuously generates shock noise that is unpleasant to a user's ears by hitting against other parts while horizontally moving.
Further, since the check valve is horizontally moved in the “Hot water supply apparatus having check valve with improved molding property” disclosed in Korean Utility Model No. 20-0474868, the check valve cannot open the hole in some cases due to dirt sticking to the valve.

Abstract

Provided is a heating device for a hot water mat that can minimize noise by a check valve for controlling flow of liquid. The heating device for a hot water mat includes: a water tank having a tub for keeping liquid and a discharge hole formed through a side of a lower portion to discharge the liquid in the tub; a heating module connected to the discharge hole and heating liquid; a separator disposed in the water tank, dividing the tub in to a first compartment at a lower portion and a second compartment at an upper portion, and having a connection hole for connecting the first compartment and the second compartment to each other; and a check valve disposed in the first compartment and opening and closing the connection hole by moving up and down by buoyancy from the liquid in the first compartment.

Description

BACKGROUND OF THE INVENTION[0001]Field of the Invention[0002]The present invention relates to a heating device for a hot water mat and, more particularly, a heating device for a hot water mat that can minimize noise by a check valve for controlling flow of liquid.[0003]Description of the Related Art[0004]An electric blanket or an electric mat that are used generally in winter can heat a portion of a floor or can achieve a heating effect for a short time, so they are generally used by many people.[0005]However, electric wires are disposed in the electric blanket or the electric mat, so there is always a danger of an electric shock accident, harmful electronic waves are generated by their electric characteristics, and the harmful electronic waves are known as being harmful to a human body.[0006]Accordingly, hot water mats employing the conventional On-Dol (underfloor heating) type and using hot water suitable for the features of Korea familiar with the On-Dol culture are recently on t...
