Pump is connected to the gas outlet 116 of check valve 110 by connecting tube 131.
The course of work of check valve 110 and air pump will be hereafter described in detail.
When cooking apparatus is not started to work or when cooking apparatus does not use air pump function, as shown in Fig. 2, cooking space
In normal pressure or barotropic state, the spring 118 of check valve 110 is in compressive state, and pressure F1 and valve chamber in cooking space
The difference of pressure F2 in 113 is less than or equal to the elastic force F3 of spring 118, that is, F1-F2≤F3, valve rod sealing member 119 are in sealing
The sealing station of air inlet 115.It should be noted that " pressure in cooking space " referred to herein is really cooking space
The pressure that interior gas applies the valve rod sealing member 119 being in contact with it, which multiplied by the atmospheric pressure value in cooking space
It is obtained with the contact area of gas and valve rod sealing member in cooking space.Similarly, " pressure in valve chamber " is really valve chamber
The pressure that interior gas applies the valve rod sealing member 119 being in contact with it, which is by the atmospheric pressure value in valve chamber multiplied by valve
What the contact area of intracavitary gas and valve rod sealing member obtained.
As shown in figure 4, air pump is evacuated according to Fig. 4 arrow direction, check valve when control device control air pump is started to work
Pressure F2 in 110 valve chamber 113 reduces, when F2 is decreased to so that the pressure F1 in cooking space and the pressure in valve chamber 113
The difference of F2 is greater than the elastic force F3 of spring 118, that is, when F1-F2 > F3, the gas in cooking space can overcome the elastic force of spring 118
Spring 118 is jacked up, so that valve rod 117 can drive valve rod sealing member 119 to move to conduction position.At this point, air pump can pass through list
Air suction process is carried out to cooking space to the valve chamber 113 of valve 110, to make cooking space be in negative pressure state, and then can be effective
Keep the fresh and mouthfeel of food.When in cooking space pressure or pumpdown time reach predetermined value when, air pump stop pumping
Operation, at this time under the active force of spring 118, valve rod sealing member 119 is pushed into sealing station.
When uncap operate when, cooking space can be made to be in communication with the outside by other steam channel (not shown), from
And the negative pressure state in cooking space can be released, and then user can normally uncap.
Preferably, the critical value for making valve rod sealing member 119 generate the pressure difference of movement is not less than 0.13N, for example, this is critical
Value can be 0.15N.That is, the difference as the pressure F1 and pressure F2 in valve chamber 113 in cooking space is greater than above-mentioned face
When dividing value, it can overcome the elastic force of spring that valve rod sealing member 119 is made to generate movement, and as the pressure F1 and valve chamber in cooking space
When the difference of pressure F2 in 113 is less than or equal to above-mentioned critical value, valve rod sealing member 119 does not generate movement.Certainly, this field skill
Art personnel, which also can according to need, sets other values for above-mentioned critical value.
Check valve and cooking apparatus according to the present utility model can pass through the pressure difference between valve chamber 113 and cooking space
The existing difference between the elastic force of spring 118, moves valve rod sealing member 119 between sealing station and conduction position, most
The function of making cooking space be in negative pressure state can be achieved eventually.Program structure is simple, assembling is convenient, is easily achieved, and can be with
Save material cost and human cost.
The utility model is illustrated by above embodiment, but it is to be understood that, above embodiment
It is only intended to the purpose illustrated and illustrated, and is not intended to limit the invention within the scope of described embodiment.This
Outside it will be appreciated by persons skilled in the art that the utility model is not limited to above embodiment, according to the utility model
Introduction can also make more kinds of variants and modifications, it is claimed that these variants and modifications all fall within the utility model
Within range.The protection scope of the utility model is defined by the appended claims and their equivalents.
