Specific embodiment

It should be noted that in the case where not conflicting, the feature in embodiment and embodiment in the application can phase Mutually combine.Below with reference to the accompanying drawings and in conjunction with the embodiments describing this utility model in detail.

It is noted that described further below is all exemplary, it is intended to provide further instruction to the application.Unless another Indicate, all technology used herein and scientific terminology are with usual with the application person of an ordinary skill in the technical field The identical meanings of understanding.

In this utility model, in the case where contrary explanation is not made, the noun of locality such as " upper and lower, top, bottom " for using is generally It is for direction shown in the drawings, or for part sheet is on vertical, vertical or gravity direction；With Sample ground, for ease of understanding and describing, " inside and outside " is referred to relative to the inside and outside of each part profile of itself, but the above-mentioned noun of locality is simultaneously It is not used in restriction this utility model.

For the water in solving when electric cooking appliance in prior art works because of inner bag, acutely there is potential safety hazard, affect rice in boiling The problem of rice-mouth sense, this utility model provide a kind of electric cooking appliance.

As shown in Figures 1 to 7, electric cooking appliance includes inner bag 10, the food steamer 20 being arranged in inner bag 10, is used for detecting bearing cavity There is the opening that diapire and/or side wall towards inner bag 10 extend to tie for the anti-overflow test section 40 of water level in 23, the bottom of food steamer 20 Structure 21, food steamer 20 have permeable region 22 and the bearing cavity 23 above permeable region 22, the opening that hatch frame 21 is surrounded Space 211 is connected with bearing cavity 23 by permeable region 22, is formed between the medial wall of the outer surface of food steamer 20 and inner bag 10 Separate space 30, separate space 30 are connected with bearing cavity 23 by open space 211；The test side of anti-overflow test section 40 is connected with bearing cavity 23 Logical.

When the electric cooking appliance using said structure carries out cooking operation, when heater element starts to heat inner bag 10 Afterwards, the water below rice comes to life, and vapor is filled to separate space 30 rapidly so that the pressure rise in separate space 30, separate space 30 Pressure reduction is produced with bearing cavity 23.Now, water will be pressed in bearing cavity 23 and contact with rice, it is achieved that water to the immersion of rice with Boil.With the aggravation of boiling water state, the pressure in separate space 30 constantly increases, so that more water are pressed into carrying in inner bag 10 In chamber 23.Now, water is fully contacted water suction with rice, boils rice with entrance and washes the stage of rice.

If it should be noted that, will there is the excessive risk of water, so as to cause to pacify in the now fluidized state aggravation of water Full hidden danger.For cooking rice being better achieved and water will not be excessive, by arranging anti-overflow test section 40, can be with effective detection bearing cavity Water level in 23, and when the water surface is risen to and contacted with anti-overflow test section 40, stop the work or reduction of heater element in time The power of heater element, so that water level falls after rise, it is to avoid excessive.When the detection range of the anti-overflow test section 40 of surface deviation, again Start heater element to be heated, to ensure that the water in bearing cavity 23 is fully contacted water suction all the time with rice, circulation according to this completes rice Meal is washed, boils the stage.
