Abstract

The utility model discloses an overflow prevention structure of an electric rice cooker. The overflow prevention structure comprises a valve cover and a valve seat movably connected with the valve cover, an air inlet and a reflux hole for installation of a reflux valve are formed at the bottom of the valve base, and an air exhaust hole is arranged on the valve cover. The overflow prevention structure is characterized in that a partitioning rib position protruding upwards is further arranged at the bottom of the valve seat, a gap is reserved between the end part of the partitioning rib position and the side wall of the valve seat, the partitioning rib position separates a cavity between the valve seat and the valve cover into an air inlet space and an air exhaust space which are independent relatively, the air inlet is arranged inside the air inlet space, and the reflux hole and the air exhaust hole are arranged inside the air exhaust space. According to the utility model, the cavity between the valve seat and the valve cover is separated into the air inlet space and the air exhaust space which are independent relatively, paths for introducing steam and soup from entering the overflow prevention structure to being exhausted are increased to a maximal extent, so that the steam and the soup are obviously reduced in temperature and pressure, and the soup can be effectively prevented from overflowing.

Description

A kind of anti-spilled structure of electric cooker

Technical field

The utility model relates to electric cooker, particularly a kind of anti-spilled structure of electric cooker.

Background technology

The electric cooker of selling on the market all has steam valve structure usually to realize no-spill function.Disclose a kind of electric cooker pot cover as patent ZL200620111887.2, it is to be provided with steam channel on pot cover component, trip and the draw-in groove snapping of steam valve by being provided with each other that steam channel and upper end are opened wide.But this cap relief valve often is subjected to the outward appearance restricted volume less, and anti-spilled structural design is fairly simple, and it is shorter to the path in exhaust steam hole to enter steam valve from water vapour, thin rice gruel, and the broken bubble DeGrain of steam valve structure, and anti-spilled performance is undesirable.And the user is in the process of using electric cooker; occur producing soup juice when causing product work and overflowing, thereby cause user's inconvenience through regular meeting not according to the correct meter phenomenon that the water ratio is cooked or cooked congee; even seriously overflow and may cause product electric leakage, user's personal safety is damaged.

Summary of the invention

The purpose of this utility model is to consider the problems referred to above and a kind of anti-spilled structure that can effectively prevent the electric cooker that overflows is provided.

The technical solution of the utility model is: a kind of anti-spilled structure of electric cooker, comprise the valve gap and the valve seat that are movably connected, the valve seat bottom is provided with air admission hole and is used to install the return port of return valve, valve gap is provided with steam vent, it is characterized in that: the valve seat bottom also is provided with the subregion muscle position to upper process, leave the space between the end of subregion muscle position and the valve seat sidewall, subregion muscle position is divided into relatively independent admission space and exhaust space with the cavity between valve seat and the valve gap, air admission hole is positioned at admission space, and return port, steam vent are positioned at exhaust space.

Above-mentioned valve gap is provided with the retaining muscle to lower process, cooperates arrangement with described subregion muscle position is interlaced up and down.

Above-mentioned valve seat bottom interior surface has certain slope, and corresponding air inlet position position is higher in the admission space, and the gap between subregion muscle position and the valve seat sidewall is lower, and corresponding return port place is minimum in the exhaust space.

Above-mentioned valve gap is provided with step, step steam vent and the retaining muscle between, and extend to steam vent under.

Above-mentioned air admission hole is higher than the valve seat bottom.

Described valve gap and valve seat are installed and removed cleaning by screwing or being fastened and connected together to make things convenient for the user.

The beneficial effects of the utility model are, make full use of the inner space of anti-spilled structure, increase steam, soup juice to the full extent from entering anti-spilled structure to the path of discharging process, make steam, the significant hypothermal step-down of soup juice and the step that stops is set below steam vent, make steam and soup juice can not form bubble, thereby prevent that effectively soup juice from overflowing.

Fig. 3 is the valve seat internal structure schematic perspective view of the anti-spilled structure of the utility model.

The specific embodiment

As shown in Figure 1 to Figure 3, when the anti-spilled structure of present embodiment electric cooker is used, be installed in the steam hole of electric cooker loam cake.Comprise the valve gap 10 and the valve seat 20 that are movably connected by modes such as fastening or screw, flexibly connect, therefore can make things convenient for the user to install and remove valve gap 10 when needed and valve seat 20 cleans owing to adopt.In the present embodiment, the two connects by manner.

As shown in Figure 3, valve seat 20 is a upper end open cavity of being made up of the sidewall of bottom and certain altitude, the bottom is provided with the air admission hole 21 that allows steam enter cavity, allow return port 22 that steam condensate (SC) refluxes and to the subregion muscle position 23 of upper process, air admission hole 21 has certain altitude from the valve seat bottom, avoid steam condensate (SC) directly to reflux from air admission hole 21, return port 22 places are equipped with the return valve 30 of silica gel material, air admission hole 21 and return port 22 lay respectively at the both sides of subregion muscle position 23, leave the space between the end of subregion muscle position 23 and valve seat 20 sidewalls.

As shown in Figure 2, valve gap 10 is provided with the steam vent 11 that allows steam discharge, retaining muscle 12 and the step 13 that blocks steam vent 11 to lower process, retaining muscle 12 is similar to subregion muscle position 23 shapes, when valve gap 10 is installed on the valve seat 20, retaining muscle 12 and subregion muscle position about in the of 23 interlaced arrangement cooperate, cavity between valve seat 20 and the valve gap 10 is divided into relatively independent admission space 1 and exhaust space 2, air admission hole 21 is positioned at admission space 1, return port 22, steam vent 11 is positioned at exhaust space 2, steam or soup juice enter and are full of admission space 1 from air admission hole 21 like this, enter exhaust space 2 through the space between subregion muscle position 23 and valve seat 20 sidewalls again, steam is discharged through steam vent 11 then, and steam condensate (SC) or soup juice flow back into the utilization of electric cooker inner loop through return port 22.Like this steam discharge the path of process long, its temperature and pressure reduces greatly, has improved no-spill effect greatly.

As shown in Figure 1 and Figure 2, step 13 between steam vent 11 and retaining muscle 12, and extend to steam vent 11 under, making steam must walk around step 13 could discharge through steam vent 11, avoids steam to blow out bubble like this by steam vent 11 time and causes and overflow.

In order to make the steam condensate (SC) in the admission space 1 or soup juice is smooth and easy, enter exhaust space 2 apace and flow back into electric cooker inside through return port 22, valve seat 20 lower surface have certain gradient, position, corresponding air admission hole 21 place is higher in the admission space 1, position, gap between subregion muscle position 23 and valve seat 20 sidewalls is lower, and corresponding return port 22 places are minimum in the exhaust space 2.
