Detailed Description

In order that the above objects, features and advantages of the present invention can be more clearly understood, a more particular description of the invention will be rendered by reference to the appended drawings. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the scope of the present invention is not limited by the specific embodiments disclosed below.

The float assembly 10, the upper cover 20 of the cooking apparatus, and the cooking apparatus 1 according to some embodiments of the present invention will be described below with reference to fig. 1 to 11.

As shown in fig. 1 to 5, an embodiment of a first aspect of the present invention proposes a float assembly 10 comprising: an exhaust valve seat 102 provided with a stopper portion; a float 116 provided on the exhaust valve seat 102, the float 116 having an exhaust passage 118, the float 116 being capable of floating up and down relative to the exhaust valve seat 102 between a floating position at which the exhaust passage 118 is sealed and a falling position at which the exhaust passage 118 is opened, the float 116 being provided with at least two exhaust holes communicating with the exhaust passage 118; the limiting matching part is arranged on the floater 116, when the floater 116 floats to the floating position, the limiting matching part and the limiting part can be matched and limit the floater 116 at the floating position, and when the limiting matching part and the limiting part are disengaged, the floater 116 can float from the floating position to the falling position.

The present invention provides a float assembly 10 comprising: a vent valve seat 102, a float 116, and a limit fitting. The limiting part is arranged on the exhaust valve seat 102, and is matched with the limiting matching part through the limiting part, so that when the cooking equipment 1 works, no pressure exists in a cooking cavity of the cooking equipment 1 in an initial stage, the floater 116 is in a natural falling state, when the temperature in the cooking equipment 1 rises, certain pressure is generated, the pressure pushes the floater 116 to move, the floater 116 floats upwards, at the moment, the exhaust channel 118 of the floater 116 is in an open state, partial cold air in the cooking cavity of the cooking equipment 1 can be exhausted out of the cooking appliance through the exhaust channel 118, and the cooking cavity is communicated with the outside atmosphere; further, when the pressure value reaches a preset value, the float 116 is located at the upward floating position, the limit matching part is matched with the limit part, and the float 116 is limited at the upward floating position, at this time, the exhaust passage 118 of the float 116 is sealed, so that the outward leakage of steam in the cooking cavity of the cooking device 1 is avoided, and the positive pressure sealing function of the cooking device 1 is realized; further, when the stop heating, the temperature in the pot reduces gradually, pressure also reduces thereupon, at this moment, because spacing cooperation portion makes float 116 still keep in this come-up position department with spacing ground cooperation, 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 intracavity, the operating efficiency when promoting the culinary art intracavity negative pressure stage, the negative pressure sealing function of cooking equipment 1 has been realized, cooking equipment 1 helps prolonging the save time of food when being in negative pressure sealing situation, user diversified user demand has been satisfied. This structure setting makes cooking equipment 1 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 float 116 only has malleation sealing ability among the correlation technique, is difficult to compromise the problem of negative pressure sealing performance. Meanwhile, the limiting part is arranged on the exhaust valve seat 102 and the limiting matching part is arranged on the floater 116, namely, the existing structures of the exhaust valve seat 102 and the floater 116 are reasonably utilized, the investment of other devices for fixing the limiting part and the limiting matching part is avoided, the transformation and production cost is reduced under the condition of ensuring the service performance of the floater assembly 10, the appearance size and the weight of the floater assembly 10 are reduced to the maximum extent, and the quality and the market competitiveness of products are improved.

More specifically, the structure of assembling the float 116 and the exhaust valve seat 102 is provided such that the float 116 is disposed on the exhaust valve seat 102 and can float up and down between a floating position at which the exhaust passage 118 is sealed and a falling position at which the exhaust passage 118 is opened with respect to the exhaust valve seat 102, that is, the structure of assembling the exhaust valve seat 102 and the float 116 restricts the movement trajectory of the float 116 such that the float 116 can move between the floating position and the falling position according to a predetermined path, thereby ensuring the smoothness and feasibility of movement of the float 116, preventing the float 116 from being stuck at a certain position of the path due to collision or jamming and preventing the cooking device 1 from failing to perform a cooking function, and at the same time, the structure is configured such that when the position-restricting fitting portion is disengaged from the position-floating to the falling position, the exhaust passage 118 is opened at this time, the cooking chamber communicates with the external environment to balance the air pressure, make the gaseous discharge valve of accessible cooking equipment 1 of culinary art intracavity arrange outward, just so can avoid the gas leakage to the inside condition of cooking equipment's upper cover 20 to take place, avoided upper cover 20 inner structure to be corroded by steam, and avoided upper cover 20 inside to breed the bacterium, also reduced sealed requirement relatively in addition, simplified the inside seal structure of upper cover 20, reduced the manufacturing cost of product. Meanwhile, at least two vent holes are formed in the float 116, so that the at least two vent holes are communicated with the vent channel 118, so that the vent channel 118 can be communicated with the space below the cover plate 202 of the cooking device and/or the space above the vent valve seat 102 through the at least two vent holes to define the flow direction of the air flow.
