Self-defoaming electric cooker

Technical Field

The invention belongs to the field of electric cookers, and particularly relates to a self-defoaming electric cooker.

Background

Electric cookers are also known as electric cookers and electric rice cookers. The electric cooker is a cooker which converts electric energy into heat energy, has various heating operation functions of steaming, boiling, stewing and the like on food, and is convenient to use, safe and reliable. The multifunctional cooking machine can cook food, can preserve heat, is clean and sanitary to use, has no pollution, saves time and labor, and is one of indispensable tools for modernization of housework.

The electric rice cooker is in the in-process that uses, often can produce a large amount of bubbles, be easily at the in-process of cooking or a kind of deep pot hot water, lead to liquid to spill over, can break the bubble through the protruding muscle in the steam valve on the lid usually, but the broken bubble effect of protruding muscle is relatively poor, can only eliminate the bubble of a small part, still have a large amount of bubbles to remain, easily make the liquid outflow in the electric rice cooker, give people's the very big inconvenience of cooking or a kind of deep pot hot water brought, for this reason, we propose from defoaming electric rice cooker and solve above-mentioned problem.

Disclosure of Invention

The invention aims to provide a self-defoaming electric rice cooker aiming at the problems.

In order to achieve the purpose, the invention adopts the following technical scheme: from defoaming electricity rice cooker, including the electricity rice cooker body, be provided with the apron on the electricity rice cooker body, the lower extreme lateral wall fixedly connected with of apron rather than assorted hollow core plate, be provided with the first through-hole that two symmetries set up on the hollow core plate, the intercommunication has a plurality of communicating pipes, and is a plurality of communicating pipe intercommunication has the hollow tube, the lower extreme intercommunication of hollow tube has the baffle, the baffle is hollow structure, and the equal circular arc design of both sides lateral wall of baffle, a plurality of air vents to leading to have been seted up to the upper and lower both ends lateral wall of baffle, the air vent intercommunication of lower extreme lateral wall has the needle-shaped pipe, be provided with the cold air duct in the baffle, and the both ends of cold air duct all run through the inner.

In the self-defoaming electric rice cooker, the cover plate is provided with two second through holes opposite to the first through holes, the second through holes are internally provided with the sealing balls, the diameter of the lower end opening of each second through hole is slightly smaller than that of each sealing ball, the width of the upper end opening of each second through hole is slightly smaller than that of each sealing ball, and the length of the upper end opening of each second through hole is larger than that of each sealing ball.

In the self-defoaming electric rice cooker, the sealing ball is fixedly connected with the needle body, and the needle body penetrates through the first through hole.

In the above-mentioned electric rice cooker of defoaming, the hollow plate is the design of toper structure, and first through-hole sets up in the position that the lateral wall of hollow plate both sides leaned on.

In the self-defoaming electric cooker, the hollow pipe is sleeved on the communicating pipe and is in sliding connection with the communicating pipe, and a plurality of return springs are fixedly connected between the baffle and the communicating pipe.

Compared with the prior art, the self-defoaming electric cooker has the advantages that:

1. according to the invention, the hollow plate is arranged, so that generated steam can be collected and discharged into the baffle plate through the communicating pipe, the steam can increase air pressure under the action of the needle-shaped pipe on the baffle plate, so that the discharged gas has certain impact force, bubbles in the electric cooker can be rapidly removed under the action of the impact air flow, and the formed steam flows back, so that food can be further heated, and the energy waste is reduced.

2. According to the invention, through the arranged cold air pipe, external air flow can enter the cold air pipe to circulate, so that the temperature of the cold air pipe is reduced, steam gathered in the hollow plate can be effectively precooled, the density is increased, and the steam is conveniently discharged from the communicating pipe.

3. Through the matching of the second through hole and the sealing ball, the sealing ball can be jacked up when the steam pressure exceeds a limit finger, so that a gap is formed at the upper end opening of the second through hole, the high-pressure steam can be conveniently discharged, and in addition, the arranged needle body can break bubbles close to the first through hole and can further puncture bubbles of accessories along with the falling back of the sealing ball.

4. According to the invention, by arranging the return spring, when high-pressure steam is discharged through the second through hole, the acting force of gas discharged from the communicating pipe is weakened, so that the return spring can drive the baffle to return under the self reaction force, and the needle tube on the baffle can vibrate up and down with a certain amplitude under the action of the self elastic force, so that bubbles of accessories can be effectively punctured by utilizing the appearance of the needle tube, and the defoaming efficiency is further improved.

5. The steam-water separator has the advantages that the hollow plate is provided with the conical structure, the sinking of steam in the hollow plate can be accelerated by utilizing the characteristics of the conical structure, in addition, the arc-shaped design of the side walls at the two sides of the baffle can realize the turbulent flow effect, and the influence of the rising steam on the downward air flow is avoided.
