Specific implementation mode
It should be noted that in the absence of conflict, the features in the embodiments and the embodiments of the present application can phase
Mutually combination.The present invention will be described in detail below with reference to the accompanying drawings and embodiments.
As shown in Figures 1 to 12, the cooking apparatus of the present embodiment includes cooking cavity 1, pumping chamber 2, air extractor 40, float
50, float driving mechanism 80 and one-way mechanism 90.Wherein, the first communicating passage 231 is equipped between pumping chamber 2 and cooking cavity 1
So that the gas in cooking cavity 1 can be extracted by pumping chamber 2.The air entry 41 of air extractor 40 is connected to pumping chamber 2.It is floating
Son 50 is movably disposed in the first communicating passage 231, and float 50 has and makes the pumping position that pumping chamber 2 is connected to cooking cavity 1
Pumping chamber 2 and 1 disconnected sealing station of cooking cavity are set and make, in a non-operative state, float 50 is in be taken out cooking apparatus
Gas position.Float driving mechanism 80 drives float 50 to be moved to sealing station, effect of the float 50 in its gravity by bleed position
Under be moved to bleed position.One-way mechanism 90 enables the gas in pumping chamber 2 to be discharged outside to by one-way mechanism 90, and makes
Ambient atmosphere can not enter pumping chamber 2 by one-way mechanism 90.
Using the technical solution of the present embodiment, cooking apparatus includes the float being movably disposed in the first communicating passage
50, float 50 has the bleed position for making pumping chamber 2 be connected to cooking cavity 1 and keeps pumping chamber 2 disconnected close with cooking cavity 1
Position (i.e. position in Figure 10 where float 50) is sealed, in a non-operative state, float 50 is in bleed position (i.e. to cooking apparatus
Position in Fig. 8 where float 50).Cooking apparatus further includes one-way mechanism 90, and one-way mechanism 90 can make the gas in pumping chamber 2
Body can be discharged outside to by one-way mechanism 90, and make ambient atmosphere that can not enter pumping chamber 2 by one-way mechanism 90.When with
After family culinary art finishes and contains and take food, pot cover can be closed.Since the food in cooking cavity 1 is warmmer, steaming can be constantly generated
Vapour so that the pressure rise in cooking cavity 1.In a non-operative state due to cooking apparatus, float 50 is in bleed position, and single
The gas in pumping chamber 2 can be enable to be discharged outside to by one-way mechanism 90 to mechanism 90.Therefore the steam in cooking cavity 1
It can be entered in pumping chamber 2 by float 50, the external world is then ultimately discharged by one-way mechanism 90.In this way, above structure can
The pressure in cooking cavity 1 is reduced, the phenomenon generation for avoiding user from uncapping difficult so as to improve user experience, solves existing
The problem of the user experience difference of cooking apparatus in technology.

Shutting mechanism 92 switches between opening state and closed state.Specifically, when control device receives pumping signal, float 50
Positioned at bleed position, control device controls air extractor 40 and is evacuated, and control switch mechanism 92, so that switching mechanism 92 is in and closes
Closed state so that pumping chamber 2 is not connected to mutually with the external world, ensures that the gas in pumping chamber 2 and cooking cavity 1 can be extracted out smoothly.And
When control device receives cooking signals, and float driving mechanism 80 fails, control device can control switch mechanism 92 beat
It opens so that pumping chamber 2 is in communication with the outside.After connection, the pressure in pumping chamber 2 is equal with ambient pressure, in cooking cavity 1
The increase of pressure, cooking cavity 1 and the pressure difference of the gas in pumping chamber 2 are also increasing therewith, when pressure difference is enough to overcome float 50
When gravity, float 50 can float up to sealing station.Above structure makes in culinary art, even if float driving mechanism 80 fails,
Cooking cavity 1 normally upper can still be pressed, and ensure the culinary art effect of cooking apparatus.
In the present embodiment, when cooking apparatus in a non-operative state when, switching mechanism 92 is in the open state.Specifically
Ground, when user culinary art finish and contain take food after, pot cover can be closed.It, can be continuous since the food in cooking cavity 1 is warmmer
Generate steam so that the pressure rise in cooking cavity 1.In a non-operative state due to cooking apparatus, float 50 is in pumping position
It sets and switching mechanism 92 is in the open state.Therefore, the steam in cooking cavity 1 can be entered by float 50 in pumping chamber 2,
Subsequently into the second communicating passage 91.Then, switching mechanism 92 can be passed through into the steam in the second communicating passage 91, finally
It is discharged outside to.Therefore, above structure can reduce the pressure in cooking cavity 1, the phenomenon generation for avoiding user from uncapping difficult, from
And user experience is improved, solve the problems, such as that the user experience of cooking apparatus in the prior art is poor.
