Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the wall-mounted electric steam generator according to the present invention.

As shown in FIG. 1, the wall-mounted electric steam generator according to the present invention has a steam outlet 11 formed at an upper portion thereof, a water supply hole 12 formed at a lower portion thereof, and a drain hole 13 formed at the bottom thereof. The body 10, the electric heater 20 is installed in the lower portion inside the body 10 to serve as a heating source for heating the water, and to detect the water level of the water contained in the body 10 A sensor (30), a pump (40) operated to replenish water into the body (10) through the water inlet (12) based on the detected value detected by the sensor (30), and the body (10) a pressure regulating unit 50 for detecting an internal pressure and adjusting the pressure, and installed at an upstream side of the pump 40 to detect a water pressure supplied to the pump, and when the water pressure is low, the pump Stop the pump to prevent idle It consists of a slip differential unit 60 for Pointing.

The body 10, the pump 40, the pressure regulating unit 50, the idle prevention unit 60, and the like are installed and assembled in a separate housing 1, and the housing has a rear portion of the housing 1. The attaching part 70 for attaching (1) to a wall surface is formed.

Steam formed by evaporation of water in the body 10 is sent out of the device via the steam outlet 11 and the steam valve (11a). At this time, a steam pipe, etc., not shown, may be connected to the steam valve 11a to install a steam pipe pipe to a place where steam is required. The steam outlet 11 in the body 10 is attached to the separator 14 for separating steam and water so that only pure steam can be discharged through the steam outlet.

In addition, the drain port 13 of the body is provided with a drain valve 17 is configured to drain the water in the body.

Since the steam generator of the present invention uses the electric heater 20 as a heating source for heating water, the apparatus can be miniaturized as compared with the case of using gas or oil, and the exhaust gas is not generated. The element is unnecessary.

The electric heater 20 may be installed inside the body 10, may be installed to surround the body 10, or any configuration as long as it can generate steam by heating and evaporating water inside the body. Good, but preferably, as shown in Figure 1, it is preferably installed on the bottom surface inside the body (10).

Furthermore, in the wall-mounted electric steam generator according to a preferred embodiment of the present invention, the electric heater 20 is heated so that the electric heater 20 can be replaced without removing water stored in the body 10. It is wrapped by the tube 21.

The sensor 30 is composed of a high level sensor 31 at the top, a medium level sensor 32, a low level sensor 33, and an extremely low level sensor 34 at the bottom thereof.

Therefore, the water level detected by the sensor 30 is transmitted to a controller (not shown), and the controller controls the on / off of the pump 40 so that the amount of water in the body 10 can be properly maintained. . That is, the operation of the pump 40 connected to the water inlet 12 is controlled in accordance with the detection values of the four high, middle and low water level sensors 31, 32, 33 and 34.

The pressure regulating unit 50, the safety valve 51 for returning the steam to the pump 40 for safety when the pressure inside the body 10 rises above a predetermined value, and a pressure regulator for adjusting the pressure ( 52, and a pressure gauge 52 indicating the pressure inside the body.

By the pressure control unit 50, the user of the wall-mounted electric steam generator according to a preferred embodiment of the present invention can easily grasp and adjust the internal pressure of the body 10, safety in emergency, such as sudden pressure rise Since the valve 51 adjusts the pressure automatically, it can be used safely.

The idle prevention unit 60 is installed between the body 10 and the pump 40 to prevent the backflow of the water from the body back to the pump and the check valve of the pump 40, A solenoid valve 62 installed upstream to selectively block the flow of water, and a low pressure valve sensor 63 installed upstream of the solenoid valve 62 to measure the water pressure of the pipe for supplying water. .

When the water stored in the body 10 is evaporated and the water level is lowered, the sensor 30 detects it and transmits it to a controller (not shown), and the controller operates the pump 40 and at the same time the solenoid valve ( Open 62). At this time, if the water pressure measured by the low pressure valve sensor 63 is less than or equal to a predetermined value, the controller notifies the outside and does not operate the pump 40 but also does not open the solenoid valve 62. In this way, the pump 40 is prevented from idling.

The mounting portion 70 includes a support member 71 having one or more locking projections 72 formed therein, and a locking hole 2 formed in the rear surface of the housing 1. The support member 71 is fixed to a position such as a nail in advance to fix the housing 1 of the steam generator. The housing 1 is detachably mounted to the wall surface by engaging the locking projection 72 in the locking hole 2.

The shape of the locking hole 2 and the locking projection 72 may have any shape as long as it can be detachably coupled to each other and can support the housing 1. In the preferred embodiment of the present invention, although the engaging projection 72 is formed in the support member 71 and the engaging hole 2 is formed on the back of the housing 1, the engaging hole is formed in the support member 71. And it may be made so that the engaging projection is formed on the back of the housing (1).

As described above, according to the present invention, it is possible to achieve miniaturization of the steam generator by heating water to generate steam by using electricity.

In addition, since the steam generator according to the preferred embodiment of the present invention is configured to be used on the wall, it is possible to maximize the utilization of the indoor space compared to the conventional steam generator installed on the floor.

In addition, since the steam generator according to a preferred embodiment of the present invention, a separator for separating steam and water is attached to the steam outlet from which the steam is discharged, it is possible to prevent the mixing of water droplets into the steam.

In addition, the steam generator according to a preferred embodiment of the present invention, even if the supply of water is accidentally interrupted by the low pressure valve sensor to stop the operation of the pump, it is possible to reliably prevent the idle of the feed water pump.
