Steam exhaust device of electric pressure cooker

Abstract

The invention discloses a steam exhaust device of an electric pressure cooker. The steam exhaust device comprises a steam exhaust pipe and a steam exhaust valve, wherein the steam exhaust valve comprises a weight dropper sleeved in a valve shell, a thimble is arranged in the weight dropper, the steam exhaust valve and the steam exhaust pipe are arranged in a coaxial line, a steam exhaust valve seat is arranged on a cooker cover, a boss is arranged in the steam exhaust valve seat, the steam exhaust valve is rotatably arranged in the steam exhaust valve seat, more than two grooves with different heights are arranged at end parts of the valve shell and the boss is connected with the grooves; and the steam exhaust valve seat is arranged in an annular shape and the boss is arranged on the inner wall of the steam exhaust valve seat. Through arranging more than two grooves with different heights at the end parts of the valve shell, when the boss positioned in the steam exhaust valve seat and the grooves with different heights are pressed and connected, the weight dropper and the steam exhaust pipe are enabled to have different sealing degrees and respectively realize three states of sealing, low steam exhaust and high steam exhaust, and whatever food is cooked, the electric pressure cooker is ensured to realize the fastest forcible steam exhaust without clogging the steam exhaust pipe or ejecting the food, thereby the safety is improved.

Description

technical field [0001] The invention relates to an electric pressure cooker, in particular to a steam exhaust device for the electric pressure cooker. Background technique [0002] The common electric pressure cooker adopts a single forced exhaust device, which is generally aimed at setting the exhaust volume when cooking fixed-shaped foods, such as rice; when using this kind of electric pressure cooker to cook porridge or soup, etc. When eating food, it will cause food such as porridge or soup to spray out, and block the exhaust pipe, etc., which has hidden dangers in safety and sanitation. [0003] Another kind of electric pressure cooker adopts stepless steam exhaust. The exhaust steam of this kind of electric pressure cooker can be adjusted steplessly between the maximum and zero. This kind of electric pressure cooker is a very good structure for professionals. Most consumers are not professionals. When cooking porridge and soup, the exhaust steam needs to be forced to ...

Problems solved by technology

[0002] The common electric pressure cooker adopts a single forced exhaust device, which is generally aimed at setting the exhaust volume when cooking fixed-shaped foods, such as rice; when using this kind of electric pressure cooker to cook porridge or soup, etc. When cooking food, it will cause food such as porridge or soup to spray out, and block the exhaust pipe, etc., which has hidden dangers in safety and sanitation

[0003] There is also an electric pressure cooker with stepless steam exhaust. The exhaust steam of this kind of electric pressure cooker can be adjusted steplessly between maximum and zero. This kind of electric pressure cooker is a very good structure for professionals. Most consumers are not professionals, and they can’t control the exhaust steam volume when cooking porridge or soup requires forced exhaust steam. It is possible to adjust too much, causing food to spew out, block the exhaust pipe, etc., causing safety and health risks. ; It is also possible that the adjustment is too small to meet the initial requirements of rapid steam exhaust and shortened waiting time
