Quieter of electrical heating cooker

Abstract

The invention relates to a muffle device applied in an electric heating cooker, which comprises an electric heating cooker body provided with a gas exhaust valve core. A weight valve is arranged on the position of a gas outlet of the gas exhaust valve core. The weight valve is formed by connecting a gas exhaust valve body and a gas exhaust valve cover. The gas exhaust valve body is cylindrical, one end of the gas exhaust valve body is provided with an inserting cavity for inserting the gas outlet of the gas exhaust valve core, and the gas exhaust valve body is provided with a valve plug matched with a gas outlet on the gas exhaust valve cover; the gas exhaust valve cover covers the outside of the gas exhaust valve body and forms a cavity with the outer surface of the gas exhaust valve body; and the gas exhaust valve body is provided with a plurality of vent holes, the gas exhaust valve cover is provided with a plurality of gas outlets, and the vent holes on the gas exhaust valve body are staggered with the gas outlets on the gas exhaust valve cover. Therefore, air flow reflects back and forth through the inner wall of the cavity of the gas exhaust valve body, so that sound wave of certain frequency, which is transmitted along the cavity body wall, emits back at mutation position in the sound source direction, and the muffle aim is achieved.

Description

Technical field [0001] The invention relates to the technical field of electric heating cookers, and particularly refers to a muffler device used in electric heating cookers. Background technique [0002] At present, various electric heating cookers have been widely used, and some of the electric heating cookers use high pressure for cooking, which can cook food faster, such as electric pressure cookers. After using these electric pressure heating cookers to cook the food, the pressure needs to be relieved. The existing pressure relief structure is composed of a straight pressure relief pipe and a gravity valve on it. The pressure relief pipe connects the high pressure gas in the pressure cooker and the external atmospheric pressure. When the gravity valve is lifted, the pressure relief tube directly releases the high-pressure gas in the pot into the external atmospheric pressure. Because the high-pressure gas is directly ejected, the pulsation of the airflow is very large, and t...

Problems solved by technology

After using these electric pressure heating cookers to cook the food, it needs to relieve the pressure. The existing pressure relief structure is composed of a straight pressure relief pipe and a gravity valve on it. The pressure relief pipe connects the high pressure gas inside the pressure cooker and the external atmospheric pressure. When the gravity valve is lifted, the pressure relief pipe directly releases the high-pressure gas in the pot to the external atmospheric pressure. Because the high-pressure gas is directly ejected, the airflow has a large pulsation and a fast flow rate to generate sound waves of certain frequencies. These pressure relief produces The noise is particularly harsh, causing discomfort to users
