Abstract

The present invention relates to a steam generator, and more particularly, to a steam generator employed in a steam disinfecting apparatus and a food steaming apparatus. An object of the present invention is to provide a steam generator, which can rapidly generate steam at an operation time point by supplying the necessary amount of water to a heating plate, operate with small power, and considerably reduce energy loss resulting from conduction or radiation due to a small volume.

Description

STEAM GENERATOR

Technical Field

[I] The present invention relates to a steam generator, and more particularly, to a steam generator employed in a steam disinfecting apparatus and a food steaming apparatus.

[2]

Background Art

[3] A conventional apparatus generates steam by filling a heating container with the necessary amount of water and heating the water.

[4] Such a conventional method has a disadvantage in that it takes a long time to heat the filled water to a boiling point. In this manner, high power consumption is required t o boil the water, and conduction or radiation from the large volume heating container causes large energy loss.

[5] In addition, when used in a hermetic space, if water previously filled to obtain the necessary amount of steam and a target temperature is deficient, it is difficult to replenish water. If water is excessive, the remaining water should be discharged.

Technical Solution

[9] According to an aspect of the present invention for achieving the object, there is provided a steam generator, wherein a heater is attached to a warming chamber supplied with water from a water supply connection tube having a one-way valve; and a heater is attached to a heating plate, the heating plate having protrusions formed thereon and a main body cover attached thereto, the main body cover having a plurality of opening portions formed therein, the warming chamber and the heating plate being connected to each other through an ejection conduit.

Best Mode for Carrying Out the Invention

[18] Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

[19] Fig. 1 is a view illustrating a steam generator according to the present invention,

Fig. 2 is an exploded view illustrating an embodiment of the steam generator according to the present invention, and Fig. 4 is a sectional view taken along line A of Fig. 1.

[20] Referring to Figs. 2 and 4, in a main body 2 of the steam generator according to the present invention, a heating plate 2C is fixedly mounted on one side of a warm water ejection conduit 2B, and a warming chamber 2A is fixedly mounted on the other side of the warm water ejection conduit 2B. A main body cover 1 is fixedly mounted at an upper portion of the heating plate 2C formed in the main body 2. A plurality of opening portions IA which are steam paths are regularly formed in the main body cover 1 in a radial direction. A heating heater 3 is fixedly mounted at a lower portion of the heating plate 2C, and an ejection heater 4 is fixedly mounted at a lower portion of the warming chamber 2A.

[21] One side of a connection tube 6 for supplying water is fixedly mounted at a side portion of the warming chamber 2A. Still referring to Fig. 4, a one-way valve 7 is mounted in the connection tube 6. A container 5 filled with water is fixedly mounted on the other side of the connection tube 6.

[22] Fig. 3 is a perspective view cut into half along line A of Fig. 1.

[23] Referring to Figs. 3 and 4, when water filled in the container 5 is supplied along the connection tube 6, the warming chamber 2 A is filled with the water. As power is supplied to the ejection heater 4, a temperature of water filled in the warming chamber 2A rises. When the water reaches a predetermined temperature, it starts to be evaporated, which is in a wet saturated steam state in which water and steam coexist. In the wet saturated steam state, the water and wet saturated steam are ejected through the ejection conduit 2B due to steam pressure. The ejected water and wet saturated steam collide against a scattering plate IB, evenly scatter in a radial direction, and collide against the heating plate 2C. Then, the wet saturated steam and high temperature water are more heated by the heating plate 2C heated to a high temperature by the heating heater 3, and turned into dry saturated steam. The dry saturated steam is ejected through the opening portions IA formed in the main body cover 1.

[24] The one-way valve formed as shown in Figs. 3 and 4 serves to prevent the water and wet saturated steam from flowing into the container 5 when the steam pressure is generated in the warming chamber 2A.

[25] As depicted in Fig. 4, the heating plate 2C is formed with protrusions. The protrusions cause the ejected water to stay between the protrusions and to slowly flow downward. If the water flows fast, non-heated water stays in a lower portion. Therefore, a water contact area is reduced in the heating plate 2C, which slows down the evaporation rate. After the water is ejected from the warming chamber 2A due to the steam pressure and the warming chamber 2A is emptied, the water is supplied again from the container 5 to the warming chamber 2 A through the connection tube 6. The ejection conduit 2B should be long as much as necessary to cause the warming chamber 2A to be sufficiently far from the heating heater 3 so that the water in the warming chamber 2 A is heated only by the ejection heater 4 and ejected by the steam pressure.

[26] Electrical leads (not shown) connected to the ejection heater 4 and the heating heater 3 and electric control circuits for controlling the heaters have been well known, and do not constitute major portions of the present invention. Thus, explanations thereof will be omitted.

[27]

Industrial Applicability

[28] The present invention provides a high efficiency steam generator which can save the time of achieving the object by rapidly generating steam at an operation time point, and reduce power consumption and energy loss.
