Description

Cooking vessel having a thermostat < RTI ID = 0.0 >

The present invention relates to a cooking vessel lid, and more particularly, to a lid of a cooking vessel which is opened or closed in accordance with the expansion of a wax. The thermostat is installed in a lid of the cooking vessel. When the temperature inside the cooking vessel exceeds a predetermined temperature, The present invention relates to a cooking container lid having a thermostat which is discharged to the outside of the container and can prevent the soup from overflowing to the outside of the cooking container.

In general, a cooking vessel such as a pot or a frying pan uses a lid to prevent foreign matter from entering the cooking process and to prevent heat loss, and the lid is equipped with a handle for opening and closing the cooking vessel.

The handle mounted on the cooking vessel lid is configured to protrude from the upper part of the lid so as to be easily handled by the hand, so that the lid can be easily opened and closed at the time of cooking.

When the food is cooked in the cooking vessel by covering the cooking vessel with the lid of this type, when the food is boiled in the cooking process, the lid of the cooking vessel is shaken by the steam pressure generated in the cooking vessel, If the pressure inside the container continuously increases, the contents such as broth which are generated in the food itself overflow to the outside of the cooking container, and the cooking container and the lid become dirty.

In addition, when the contents overflow to the outside of the cooking container as described above, the seasoning of the food is leaked to the outside, so that the cooked food can not be cooked, and when the flame of the heating mechanism is turned off by the overflowing contents, It may cause a safety accident such as leakage to the outside.

Therefore, in order to solve the above-mentioned problems, the conventional technique has adopted a means for discharging the steam generated in the cooking process to the lid of the cooking container. For example, one or more steam outlets are formed in the lid of the cooking vessel to discharge the steam generated in the cooking process of the food through the steam outlet.

However, since such a steam outlet is always exposed in a state of being open to the lid, the steam inside the cooking vessel is leaked from the beginning and the cooking time becomes longer. Further, when the food starts to boil, There is a problem that can not be done.

In particular, when the steam pressure in the cooking vessel is rapidly increased, the lid of the cooking vessel is lifted, and the lid is shaken by the steam to generate noise, or the contents are often flooded to the outside of the cooking vessel, , The user separates the lid from the cooking container to prevent the overflow. However, this causes the internal steam to flow out rapidly, resulting in a longer cooking time of the food, resulting in poor cooking efficiency.

Another known technique is disclosed in Korean Utility Model Registration No. 359497 entitled "Overflow prevention cooking vessel lid ". The overflow prevention cooking vessel lid has a steam outlet formed at one side of the handle mounted on the upper part of the lid In order to operate the steam outlet, a complicated structure such as a supplementary spring, a high-elasticity spring, a cover plate, a sensing plate, a stopper, a lever and a pressure lever is employed, thereby lowering price competitiveness. It is almost impossible to apply it.

According to another conventional technique, a Korean Utility Model Registration No. 368219 discloses a steam control member, which is rotatably installed on a fixed plate and a fixed plate, and is composed of a rotary plate having a plurality of rotary discharge holes formed on the outer peripheral surface thereof, Structure has been proposed, but such a structure is inconvenient to manually adjust the vapor pressure.

FIG. 1 is an exploded perspective view showing a lid of a cooking vessel provided with a thermostat according to the present invention, and FIG. 2 is a sectional view showing a lid of a cooking vessel provided with a thermostat according to the present invention.

Referring to the drawings, the lid of the cooking utensil provided with the thermostat according to the present invention is installed on the upper part of the lid so that the lid can be held by the user, and an exhaust hole 113 for discharging the steam to the outside is formed A connector 120 for connecting the handle and the lid of the cooking container; a valve 130 installed in the connector 120 for interrupting the discharge of steam; a connector 120 installed in the connector 120, And a thermostat 140 for generating a displacement of the valve 130 to open and close the exhaust hole 113.

The lid 100 is formed with a through hole 101 through which the connector 120 is inserted and the upper end of the connector 120 is protruded. The lid 100 of the cooking container is made of glass, metal, or the like.

The handle 110 is provided at the center of the lid 100 so that the lid 100 can be wrapped by the user so that the lid can be separated from the heated cooking container. The handle 110 includes a grip portion 111 that can be gripped by a user's hand, a holder 112 coupled with the connector 120 protruding through the through hole 101 formed in the lid 100, a holder 112 And an exhaust hole 113 for exhausting the steam.

The grip portion 111 has a thickness and a length that the user can hold by hand and a holder 112 is integrally formed on one side of the grip portion 111. [ The holder 112 integrally formed with the grip portion 111 is positioned at the center of the lid 100 of the cooking utensil and is fixed to the lid 100 of the cooking utensil by the connector 120.

Particularly, a coupling hole 116 for screwing the connector 120 is formed on the lower surface of the holder 112 which contacts the upper surface of the lid 100 of the cooking utensil. The coupling hole 116 is formed in the holder 112 And is connected to the formed exhaust hole 113.

A valve 130 is provided in the exhaust hole 113 formed in the holder 112 to control the opening and closing of the exhaust hole 113. The valve 130 is made of a material having heat resistance and increases the adhesion between the valve seat 114 and the valve 130 when placed on the valve seat 114 formed in the connector 120 And is made of a material exhibiting an elastic restoring force so that it can be held.

A coil spring 115 is provided at an upper portion of the valve 130 so that the coil spring 115 exerts an elastic force so that the valve 130 can be brought into close contact with the valve seat 114. Therefore, the valve 130 is brought into close contact with the valve seat 114 by the elastic force exerted by the coil spring 115 at a normal time (in a state in which the wax does not expand).

The connector 120 passes through the lid 100 and is screwed to the holder 112 of the handle 110. The connector 120 passes through the through hole 101 formed in the lid, And a fastening part 124 screwed to the fastening hole 116 of the holder.

An inlet hole 121 through which the steam flows into the coupling part 124 is formed and connected to the exhaust hole 113 formed in the holder 112 so as to be connected to the connector 120 through the inlet hole 121. [ And the inflow steam is discharged to the outside of the lid 100 through the exhaust hole 113.

At this time, the inlet hole 121 formed in the connector 120 is formed with the inclined surface 122 to pressurize the steam introduced into the inlet hole 121 to smooth the opening and closing of the valve 130. That is, the inlet hole 121 is formed with the inclined surface 122 whose diameter decreases from the lower part to the upper part.

When the inclined surface 122 is formed in the inlet hole 121 as described above, the steam introduced into the inlet hole 121 is pressurized through the inlet hole 121, So that the steam can be discharged quickly.

Meanwhile, the thermostat 140 for moving the valve 130 according to a temperature change is installed in the connector 120 as described above. The thermostat 140 is composed of a wax chamber 142, a piston 144 and a guider 146. The wax chamber 142 is supported by the connector 120 and has a receiving portion in which the wax 141 is filled .

The wax chamber 142 has a cylindrical shape with an opened upper end and is filled with wax 141 and a supporter 125 for fixing the wax to the connector 120 at the lower end peripheral surface is formed and fastened to a fastening means such as a bolt The wax chamber 142 is fastened to the connector 120 and fixed.

A guider 146 is installed on the opened upper end of the wax chamber 142. The guider 146 has a thread formed on the lower end peripheral surface of the guider 146, So that the wax chamber 142 and the guider 146 are screwed together.

At this time, an o-ring (not shown) is interposed between the wax chamber 142 and the guider 146 to maintain airtightness when the wax chamber 142 and the guider 146 are fastened. The guider 146 installed on the upper part of the wax chamber 142 is formed with a guide hole 146a for guiding the piston 144 operating according to the expansion of the wax 141 to move linearly.

The upper end of the piston 144 is connected to the valve 130 so that the valve 130 is placed in the valve seat 114 in accordance with the linear movement of the piston 144 to prevent the steam from escaping or from the valve seat 114 So that the steam is discharged through the exhaust hole 113 formed in the handle 110.

The operation of the cooker with the thermostat according to the present invention will now be described with reference to FIG.

3 is an operational sectional view showing a lid of a cooking vessel provided with a thermostat according to the present invention. Referring to the drawings, when a lid 100 is covered with an upper part of a cooking container in a state that contents are contained in the cooking container, when the contents are heated by a heating device such as a gas stove, steam starts to be generated from the inside of the cooking container .

Thus, the steam generated by the heating of the cooking vessel heats the thermostat 140 installed in the lid 100 to expand the wax 141. As the wax 141 expands due to the steam, the piston 144 is guided and guided by the guide hole 146a of the guider 146 to open the valve 130 seated on the valve seat 114. At this time, the coil spring 115 installed on the valve 130 has a compressed state.

When the valve 130 is opened as described above, the steam is discharged through the opened valve seat 114 to the outside of the lid through the exhaust hole 113 formed in the holder 112 of the handle 110, The pressure is lowered so that the contents do not boil over.

On the other hand, when heating of the cooking vessel is stopped, the internal temperature of the cooking vessel is lowered, and the wax 141 that has expanded expands. When the wax 141 is contracted as described above, the piston 144 descends and the valve 130 separated from the valve seat 114 is positioned on the valve seat 114 and the inlet hole 121 ).

At this time, the coil spring 115 in the compressed state provided on the valve 130 is brought into close contact with the valve seat 114 while the elastic force is exerted so that the valve 130 faces the valve seat 114 The inlet hole 121 of the connector 120 is closed to maintain the airtight state.

According to the lid of the cooking vessel having the thermostat according to the present invention, the thermostat 140 is installed on the lid covering the upper part of the cooking vessel, and the steam is supplied to the outside of the cooking vessel until the internal temperature of the cooking vessel becomes a predetermined temperature. When the internal temperature of the cooking container exceeds a predetermined temperature, the steam is discharged, thereby preventing the contents from boiling and overflowing, maximizing the heat efficiency, and enabling quick cooking.

While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims. .
