Background
Nowadays, cooking equipment is widely applied to daily life of people due to the advantages of convenience and quickness in operation, good cooking taste and the like. When the cooking equipment works, in order to discharge the cold air in the cooking cavity of the cooking equipment, a floater capable of floating up and down freely is arranged on an upper cover of the cooking equipment, and the discharge of the cold air is realized by the floating of the floater. When cooking equipment is in negative pressure sealing state, help prolonging the save time of food, but among the relevant art, cooking equipment only possesses the ability that utilizes the float to carry out the positive pressure sealing, promptly, can only carry out the sealed of single direction, can't realize positive, negative pressure culinary art, causes user experience poor.
Disclosure of Invention
The present invention is directed to solving at least one of the problems of the prior art or the related art.
To this end, a first aspect of the present invention proposes an upper cover of a cooking apparatus.
A second aspect of the present invention proposes a cooking apparatus.
In view of this, a first aspect of the present invention provides an upper cover of a cooking apparatus, including: the cover body is provided with a limiting part and a hinged part for hinged installation; the floater is arranged on the cover body and can float up and down between a floating position enabling the exhaust channel to be sealed and a falling position enabling the exhaust channel to be opened relative to the cover body; the limiting matching part is arranged on the floater, the floater floats to the floating position, the limiting matching part and the limiting part can be matched and limit the floater at the floating position, and when the limiting matching part and the limiting part are disengaged, the floater can float from the floating position to the falling position.
The invention provides an upper cover of a cooking device, which comprises: lid, float and spacing cooperation portion. By arranging the limiting part and the limiting matching part, when the cooking equipment works and is in an initial stage, no pressure exists in a cooking cavity of the cooking equipment, the floater is in a natural falling state, when the temperature in the cooking equipment rises and further generates certain pressure, the pressure pushes the floater to move, so that the floater floats upwards, at the moment, an exhaust passage of the floater is in an opened state, partial cold air in the cooking cavity of the cooking equipment can be exhausted out of the cooking appliance through the exhaust passage, and the cooking cavity is communicated with the outside atmosphere; further, when the pressure value reaches a preset value, the floater is located at the floating position, the limiting matching part is matched with the limiting part and limits the floater at the floating position, at the moment, an exhaust channel of the floater is sealed, steam in a cooking cavity of the cooking equipment is prevented from leaking outwards, and the positive pressure sealing function of the cooking equipment is realized; further, when the stop heating, the temperature in the pot reduces gradually, pressure also reduces thereupon, this moment, because the cooperation of spacing cooperation portion and spacing portion makes the float still keep in this come-up position department, the culinary art intracavity is in encapsulated situation always, so, the atmospheric pressure value in the culinary art intracavity is less than external atmospheric pressure value, avoid outside steam to get into the culinary art chamber, ensure to the efficiency of bleeding in the culinary art chamber, the operating efficiency when promoting the culinary art intracavity negative pressure stage, the negative pressure sealing function of cooking equipment has been realized, the save time that helps extension food when cooking equipment is in negative pressure sealing situation, user diversified user demand has been satisfied. This structure setting makes cooking equipment all have sealed function under malleation, negative pressure, and then makes when the edible taste of richening food, can realize the purpose of long-time preservation food, has avoided the waste of food, has richened the function of product, has promoted the performance of product, has solved in the correlation technique float and only has malleation sealing ability, is difficult to compromise the problem of negative pressure sealing performance.
More specifically, an assembly structure of a floater and a cover body is arranged, so that the floater is arranged on the cover body and can float up and down between a floating position and a falling position relative to the cover body, wherein the floating position enables an exhaust channel to be sealed, and the falling position enables the exhaust channel to be opened, namely, the assembly structure of the cover body and the floater limits the motion track of the floater, so that the floater can move between the floating position and the falling position according to a preset path, the smoothness and feasibility of the movement of the floater are ensured, the situation that the cooking equipment cannot realize the cooking function due to the fact that the floater is clamped at a certain position of the path due to collision or clamping stagnation is avoided, meanwhile, when the limit matching part is matched with the limit part, the floater can float from the floating position to the falling position, the exhaust channel is opened at the moment, the cooking cavity is communicated with the external environment to balance air pressure, and the air in the cooking cavity can be discharged through, therefore, the condition that gas leaks into the upper cover is avoided, the internal structure of the upper cover is prevented from being corroded by steam, bacteria breeding inside the upper cover is avoided, the sealing requirement is relatively reduced, the sealing structure inside the upper cover is simplified, and the production cost of products is reduced.
