Noise attenuator for pressure rice pot

The present invention relates to a noise attenuator for a pressure cooker, and more particularly, to a pressure cooker for attenuating loud noise generated when steam is discharged from a steam discharge part of a pressure cooker lid.

A pressure cooker is a kitchen utensil that maintains an inner container at a high pressure to increase the heating temperature at a normal pressure, thereby making the cooking process quick and at the same time improving the taste of the rice. When the pressure inside the pressure cooker is higher than a predetermined set pressure, the steam discharge portion is installed so that the steam is discharged, the steam discharge portion is often implemented in a structure in which a pressure addition is seated on the discharge nozzle discharged steam. With this structure, when the steam pressure inside the pressure cooker becomes higher than the predetermined pressure, the high pressure steam is discharged through the discharge nozzle while the pressure is shaken from side to side, thereby preventing the internal pressure from being higher than the set pressure.

However, when the high pressure steam is discharged through the steam discharge unit, a large noise is generated. Especially, when the capacity of the pressure cooker is large, for example, a pressure cooker used in a restaurant, the noise generated is very large and people around It was hard to talk.

The present invention was created to solve the above problems, it can be used in the existing pressure cooker, it is an object of the present invention to provide a pressure reducer for a pressure cooker that can attenuate the noise generated during steam discharge.

Figure 2 is a cross-sectional view of the noise attenuator of Figure 1,
3 is a view for explaining a steam flow path of the noise damper of FIG.

Hereinafter, with reference to the accompanying drawings a silencer for a pressure cooker according to the present invention will be described in detail.

1 is a view for explaining that the noise attenuator according to the present invention is installed in the steam discharge unit of the pressure cooker lid, Figure 2 is a cross-sectional view of the noise attenuator of Figure 1, Figure 3 is a steam movement of the noise attenuator of Figure 2 It is a figure for demonstrating a flow path.

As shown, the silencer 100 for the pressure cooker according to the present invention, as covering the steam discharge portion (T) of the pressure cooker lid (L), having an inner wall (11) and an outer wall (12) is open on one side A cup-shaped body portion 10; A plurality of inlet holes 20 formed in the inner wall 11 and into which steam discharged from the vapor discharge unit T flows; It is formed on the outer wall 12, a plurality of discharge holes 30 through which the steam introduced into the inlet hole 20 of the inner wall 11; is characterized in that it comprises a. At this time, a plurality of pulps 40 are installed between the inner wall 11 and the outer wall 12, the seating end and the inner wall 11 of the body portion 10 is seated on the pressure cooker lid (L) with a flexible material. Cushion layer 50 is formed.

The pressure cooker is to cook a food such as rice by using gas or electricity as fuel, and has a structure having a steam discharge part T for discharging steam when the steam pressure therein exceeds a predetermined value. The steam discharge unit (T) is implemented in various ways, for example, in the case of a pressure cooker using gas as a fuel is installed in the lid (L) discharge steam (T1) and the discharge nozzle (T1) is discharged Composed of a pressure weight (T2) to be seated. In the present embodiment, a pressure cooker using gas as an example will be described, but of course, it can be applied to a pressure cooker using electricity.

Body portion 10, covering the steam discharge portion (T) on the upper portion of the pressure cooker lid (L), has a form of a double cup having an inner wall 11 and the outer wall 12 as a whole. The body portion 10 is not deformed even by high-pressure and high-temperature steam, and also preferably made of a metal material, for example, stainless steel, which is not easily corroded.

The body portion 10 is provided with a handle 13 having good thermal insulation. The handle 13 prevents burns when moving the muffler of the present application.

The inflow hole 20 is a place where steam discharged from the vapor discharge part T flows in, and is formed on the inner wall of the body part 10, preferably on the upper ceiling side of the body part 10.

The discharge hole 30 is a place where steam introduced into the inlet hole 20 is discharged to the outside, and a plurality of discharge holes 30 are formed on an outer wall, preferably a side surface of the body portion 10.

In order to prevent the inlet hole 20 and the outlet hole 30 from facing each other, and in order to allow the inlet steam to move as long as possible, the inlet hole 20 is formed in the inner wall upper ceiling (11a) , The discharge hole 30 is formed on the outer wall 12 side. Accordingly, the high pressure steam introduced into the inlet hole 20 of the upper ceiling 11a flows downwardly and passes through the inner wall 11 and the outer wall 12, and then is discharged to the discharge hole 30. Noise is attenuated as it is lowered.

On the other hand, the size of the inflow hole 20 formed in the upper ceiling (11a) is formed larger than the discharge hole 30 formed on the side wall 12 side. Since the area formed by the upper ceiling 11a is smaller than the area of the outer wall 12 side, the number of inflow holes 20 formed in the upper ceiling 11a is the discharge hole 30 formed in the outer wall 12 side. It must be smaller than the number of). Nevertheless, in order for the total area formed by the inlet hole 20 to be at least equal to or larger than the total area formed by the outlet hole 30, the size of the inlet hole 20 is larger than the size of the outlet hole 30. .

If the total area formed by the inlet hole 20 is smaller than the total area formed by the outlet hole 30, the steam introduced into the inlet hole 20 does not completely escape to the outlet hole 30, thereby reducing noise. Becomes smaller. Therefore, in order to maximize the noise attenuation effect, the total area formed by the inlet hole 20 should be larger than the total area formed by the discharge hole 30, and in order to enable this, the size of the inlet hole 20 is the discharge hole 30. It must be greater than the size of.

The baffle 40 is alternately provided between the inner wall 11 and the outer wall 12. The baffle 40 forms a winding path between the inlet hole 20 and the outlet hole 30 to lower the vapor pressure in the process of the steam introduced into the inlet hole 20 is discharged to the outlet hole 30 This increases the noise attenuation effect.

The cushion layer 50 prevents the surface of the lid L from being damaged when the body portion 10 is seated on the pressure cooker lid L, and at the same time, the pressure weight T2 of the steam discharge portion by the steam pressure. The impact sound is generated when bumping while moving in the left and right directions, or prevents from moving from the pressure cooker lid (L) by the vibration during steam discharge. The cushion layer 50 is made of a material having good heat resistance, for example silicone rubber, so as not to be deformed even at high temperature steam.

Next, the operation of the pressure reducer for the pressure cooker of the above-described structure will be described.

In order to attenuate the noise generated in the pressure cooker, the noise reducer of the present application covers the pressure cooker lid (L) to cover the steam discharge unit (T).

When the steam pressure inside the pressure cooker exceeds the set value, the steam is discharged through the steam discharge unit (T) in this process, the pressure weight (T2) is severely swinging in the left and right directions, a large noise is generated with the steam. As shown in FIG. 3, the steam and the noise are introduced into the inlet hole 20 and then discharged through the inlet hole 30 after passing through the flow path formed by the baffle 40. In this process, the high pressure steam is converted to low pressure steam, thereby reducing the noise.

Although the present invention has been described with reference to one embodiment shown in the drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent other embodiments are possible.
