A method and an alarm device for preventing water in a pot from being boiled dry

Abstract

The invention discloses a method and alarming device for preventing water in a pot from being burnt out. The alarming device provided with a sound alarm or a light alarm and used for preventing the water in the pot from being burnt out is arranged on a pot cover of a water boiling pot, an air guiding hole on a base of the alarming device is aligned to an air hole on the pot cover, so that steam generated when liquid in the pot is heated penetrates through the air guiding hole to impact a front section portion of a turning cover on the alarming device, and the turning cover at an initial position rotates. Simultaneously, a reset bracket is overturned under the gravity effect, and the turning cover keeps a state that the front end is warped upwards under the steam effect. When steam pressure in the pot is reduced due to the fact that water is almost burnt out, the front end of the turning cover falls under the gravity effect, and the rear end of the turning cover is warped upwards. After the rear end of the turning cover is warped upwards, an alarm switch is triggered, the sound or light alarm sends an alarming signal indicating that the water is burnt out, and a purpose of preventing the water in the pot from being burnt out is achieved. The method and alarming device has the advantage of being simple in structure, convenient to use, low in manufacture cost and suitable for various heating containers.

Description

technical field [0001] The invention relates to a method and an alarm device for preventing water in a pot from drying out, and belongs to the technical field of preventing water in a pot from drying out. Background technique [0002] In cooking activities, it often occurs that the pot is placed on the fire and the person leaves, thereby causing the water in the pot to be boiled dry or the food to be scorched; , kettles, boilers, etc.), when heating, since the lid is covered, it is impossible to judge how much water remains in the container covered with the lid, which is very inconvenient for the user. In order to solve these problems, many technical solutions for preventing dry pots from being burned have been disclosed in the prior art. Although these technical solutions can prevent dry pots, most of them need to adopt special containers and cannot effectively utilize existing heating. container.

Problems solved by technology

[0002] In cooking activities, it often occurs that the pot is placed on the fire and the person leaves, thereby causing the water in the pot to be boiled dry or the food to be scorched; , kettles, boilers, etc.), when heating, because the lid is covered, it is impossible to judge how much water remains in the container covered with the lid, which is very inconvenient for the user.

In order to solve these problems, many technical solutions for preventing dry pots from being burned have been disclosed in the prior art. Although these technical solutions can prevent dry pots, most of them need to adopt special containers and cannot effectively utilize existing heating. container

Therefore, the existing technology for preventing the water in the pot from drying out not only generally has the problem that the existing heating container cannot be effectively used, but also has the problems of complex structure, inconvenient use, and high production and use costs.
