Description

HOT WATER CIRCULATION TYPE ELECTRIC THERMAL MATTRESS
SYSTEM WITH HUMIDIFYING FUNCTION
Technical Field
The present invention relates, in general, to electric thermal mattresses and, more particularly, to a hot water circulation type electric thermal mattress system, in which a hot water circulation tube is arranged in a cloth mattress unit, hot water is fed from a water container to the hot water circulation tube, and a steam outlet is formed through the water container to discharge steam from the container to air in a room during a water heating operation of the container, thereby being safely used as a heating apparatus, having a humidifying function in addition to its intrinsic heating function, and being manufactured at a low production cost.
Background Art
As well known to those skilled in the art, conventional electric mattresses each include an electric heating wire arranged in a cloth mattress unit. When such an electric mattress is switched on, the heating wire heats the cloth mattress unit to a desired temperature, thus allowing a user to use the hot mattress.
However, such conventional electric mattresses are problematic in that excessive electric currents may be momentarily applied to the heating wire situated in the cloth mattress unit to cause a user on the mattress to be burned or a fire to break out at the mattress unit due to the short circuit of the heating wire. In addition, when such electric mattresses are in use, harmful electromagnetic waves are radiated from the heating wires to cause harm to users of the mattresses. Furthermore, the electric mattresses have another problem that they are difficult to clean with water, due to the heating wires arranged inside the cloth mattress bodies, thereby hindering users from using clean cloth mattresses.
Korean Utility Model Registration No. 20-0195281 discloses an electric boiler type mattress system in which hot water heated by the heater flows into a mattress body. This conventional mattress system is advantageous in that it prevents harmful electromagnetic waves from being radiated to users because of employing engine oil as a heat source. However, the conventional mattress system has a problem that it is difficult to be cleaned because the mattress system is inseparably formed in a single structure, and thus hindering the mattress from being cleaned. In addition, the mattress system has another problem in that its cost of fabrication is very high.
Disclosure of the Invention
Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and an object of the present invention is to provide a hot water circulation type electric thermal mattress system with a humidifying function, which is not only used as a safe heating apparatus but also carries out a humidifying function, and which is manufactured at a low cost.

A bypass tube extends between the water supplying chamber and the water heating chamber and functions as a water supply tube for supplying water from the water supplying chamber to the water heating chamber when a water level in the water heating chamber is not higher than a predetermined reference level. The first power switch is installed at the predetermined portion of the bypass tube, with the control unit controlling the operation of the first electronic valve to control the amount of water flowing from the water supplying chamber to the water heating chamber through the bypass tube.
A steam outlet is formed on a wall of the water heating chamber for discharging steam from the water heating chamber to air outside the container and thereby humidifying the air.
As described above, a hot water circulation type electric thermal mattress system with a humidifying function of the present invention, includes a flexible water circulation tube arranged in a cloth mattress unit in the form of a closed circuit and feeds hot water from a water heating chamber provided with a heater through a water feed pipe to the water circulation tube, thereby being safely usable without the problem of rapid heating.
A steam outlet formed on the water heating chamber discharges steam to air outside the container during the water heating operation of the heater, thereby humidifying the air inside the room containing the mattress system of the present invention. Furthermore, the water feed pipe can be desirably separated from the water circulation tube arranged in the cloth mattress unit, thereby being easily cleaned, when the cloth mattress unit is used for a long time and becomes dirty.
Brief Description of the Drawings

Fig. 1 is a perspective view of a hot water circulation type electric thermal mattress system consisting of a mattress unit and a hot water supplying unit in accordance with the preferred embodiment of the present invention, with the mattress unit being partially broken to show the arrangement of a hot water circulation tube inside a cloth mattress unit; and
Fig. 2 is a sectional view, showing the internal construction of a water container of the hot water supplying unit included in the mattress system of this invention.
Best Mode for Carrying Out the Invention
Reference now should be made to the drawings, in which the same reference numerals are used throughout the different drawings to designate the same or similar components.
As shown Figs. 1 and 2, a hot water circulation type electric thermal mattress system 100 with a humidifying function (hereinafter, referred to as the electric thermal mattress system) in accordance with a preferred embodiment of the present invention is mainly comprised of a flat cloth mattress unit 10, a water container 20 for containing and heating the water, a flexible water feed pipe 30 extending between the mattress unit 10 and the water container 20, and a water circulation pump 40 mounted on a predetermined portion of the water supply line 31 of the water feed pipe 30.
Although the mattress unit 10 is depicted in the form of a conventional thermal mattress in the drawing for ease of illustration, one of furniture and clothing, such a sofa, bedclothes or the like, may be employed in the place of the conventional heating insulation mattress.
A flexible water circulation tube 11 is arranged in the mattress unit 10 for circulating hot water from the water heating chamber 24 of the container 20. The water circulation tube 11 is arranged in the form of a closed circuit to be evenly distributed. The inlet end 11a of the water circulation tube 11 and its outlet end l ib are connected to one side of a connector 13 provided at the corner of the mattress unit 10. The water supply line 31 of the water feed pipe 30 and its water return line 32 are detachably attached to the another side of the connector 13 that is opposite to the side connected with both inlet end 11a and outlet end 1 lb.
Thus, the inlet end 11a of the water circulation tube 11 is connected to the water supply line 31 of the water feed pipe 30 through the connector 13, while the outlet end lib is connected to the water return line 32 of the water feed pipe 30 through the connector 13. When it is required to clean the mattress unit 10, both the water supply line 31 of the water feed pipe 30 and the water return line 32 thereof are separated from the connector 13 so as to clean the mattress unit 10, thus enabling the heating insulating electric mattress system 100 to be kept clean.
The water container 20 defines a water containing cavity partitioned into the water supplying chamber 22 and the water heating chamber 24 by a partition wall 21.
The water inlet 23 is formed through the top wall of the water supplying chamber 22 for supplying the water therein, and closed by an openable plug 25.
A first level sensor 33 is mounted on the inner surface of the sidewall of the water supplying chamber 22 for sensing the water level inside the water supplying chamber 22.
The water heating chamber 24 is positioned under the water supplying chamber 22. A bypass tube 36 extends from the water supplying chamber 22 to the water heating chamber 24. The first electronic valve 35 is installed at a predetermined portion of the bypass tube 36. The bypass tube 36 is used as a water supply tube for supplying water from the water supplying chamber 22 to the water heating chamber 24 when a water level in the water heating chamber 24 is not higher than a predetermined reference level. The first electronic valve 35 is controlled by a control unit (a printed circuit board, not shown) installed on the inside surface of the water container 20 and controls the amount of the water flowing from the water supplying chamber 22 to the water heating chamber 24 through the bypass tube 36.
A heater 50 is installed in the water heating chamber 24. The heater 50 is supplied with electric currents from an external power source and heats water contained in the water heating chamber 24 above the predetermined temperature.
The water supply line 31 of the water feed pipe 30 is connected at its first end to the water heating chamber 24. The water circulation pump 40 forcibly circulates hot water heated by the heater 50 installed in the water heating chamber 24 from the water supply line 31 to the mattress unit 10.
The second electronic valve 38 is installed on the water supply line 31 at a position around the water circulation pump. The second electronic valve 38 controls the amount of the hot water flowing along the water supply line 31 by the operation of the water circulation pump 40, and prevents the hot water flowing along the water supply line 31 from leaking when both the water supply line 31 of the water feed pipe 30 and its water return line 32 are separated from the connector 13 for the cleaning of the mattress unit 10. A steam outlet 27 is formed through a wall of the water heating chamber 24. The steam outlet 27 discharges the steam from the water heating chamber 24 to the air outside the water container 20, thereby humidifying the air.
The water return line 32 of the water feed pipe 30 is connected at its first end to the water heating chamber 24. The water return line 32 is also connected at its second end to the outlet end lib of the water circulation tube 11 through the connector 13 provided at the corner of the mattress unit 10, so the hot water is returned to the water heating chamber 24 after circulating through the water circulation tube 11 positioned in the mattress unit 10 so as to heat the mattress unit 10.
The second level sensor 34 is mounted on the inside surface of the sidewall of the water heating chamber 24 to sense the water level in the water heating chamber 24. A drain port 28 is formed in the lower portion of the water heating chamber 24. The drain port 28 drains water from both the water supplying chamber 22 and the water heating chamber 24, when the electric thermal mattress is required to be cleaned or will not be used for a long time.
A transparent level checking window 26 is vertically formed through the front wall of the water container 20, so that a user can check the amount of water filling both the water supplying chamber 22 and the water heating chamber 24 through the level checking window 26. An automatic temperature controller 29a is installed on the front wall of the water container 20 near the level checking window 26, a power switch 29b is installed on the front wall of the water container 20 at a position around the automatic temperature controller 29a and a signal lamp unit 29c is installed on the front wall of the water container 20 at a position around the power switch 29b. The automatic temperature controller 29a controls the temperature of the hot water heated by the heater 50 by controlling the amount of the electric current supplied to the heater 50 installed in the water heating chamber 24. The power switch 29b controllably applies electric power from an external power source to the heater 50 and the water circulation pump 40. The signal lamp unit 29c displays light signals indicating the power supply to the water container 20 and the water supply to the water supplying chamber 22.
An electric cord 12 is extended from one side wall of the water container 20, and an electric plug 14 is connected to the outer end of the electric cord 12. A heat insulating material 15 is inserted between the inner wall of the water container 20 and the outer wall thereof. The operating process of the electric thermal mattress system 100 of the present invention will be briefly described in the following.
First of all, the plug 25 is removed from the water inlet 23 of the water supplying chamber 22, a desired amount of the water is supplied to the water supplying chamber 22, and the plug 25 is returned into the water inlet 23. Thereafter, the electric plug 14 is connected to an electric outlet (not shown) of the external power source. When the electric switch 29b is turned on, the heater 50 installed in the water heating chamber 24 of the water container 20 is operated along with the water circulation pump 40 exteriorly mounted on the outside of the water container 20. The water is supplied from the water supplying chamber 22 to the water heating chamber 24 through the bypass tube 36 extending therebetween. When the predetermined amount of the water is supplied to the water heating chamber 24, the second level sensor 34 installed on the inside of the sidewall of the water heating chamber 24 senses the water level in the water supplying chamber 24 and transmits a sensing signal to the control unit (not shown). Then, the control unit controls the operation of the first electronic valve 35 installed at the predetermined portion of the bypass tube 36 to control the amount of the water flowing from the water supplying chamber 22 to the water heating chamber 24 through the bypass tube 36.
Thereafter, when the automatic temperature controller 29a is rotated clockwise to set a predetermined temperature, the heater 50 heats the water in the water heating chamber 24. The hot water heated by the heater 50 feeds into the water circulation tube 11 arranged in the mattress unit 10 through the water supply line 31 of the water feed pipe 30 by the operation of the water circulation pump 40. After circulating the water circulation tube 11, the hot water is returned to the water heating chamber 24 through the water return line 32 of the water feed pipe
30.
The hot water returned to the water heating chamber 24 is also heated by the heater 50 and then feeds into the water circulation tube 11 arranged in the mattress unit 10 through the water supply line 31 of the water feed pipe 30. While the above-described process is continuously repeated, the temperature of the hot water circulating the water circulation tube 11 reaches the predetermined temperature. Furthermore, steam is discharged from the water heating chamber 24 to the air outside the container 20 during the water heating operation of the heater 50. Accordingly, the mattress system 100 humidifies the air inside the room using the steam.
When the mattress unit 10 of the mattress system 100 becomes dirty because the mattress system 100 has been used for a long time, the water supply line 31 of the water feed pipe 30 and the water return line 32 thereof can be simply separated from the connector 13, allowing cleaning of the mattress unit 10. In this case, the water remaining in the water circulation tube 11 arranged in the mattress unit 10 does not matter because the water does not affect to the operation of the mattress system 100.
