A sealing member 100 for an oven according to an embodiment of the first aspect of the present invention will be described with reference to fig. 1 to 10.
As shown in fig. 1, a sealing member 100 for an oven according to an embodiment of the first aspect of the present invention includes at least one sealing strip 101, the sealing strip 101 including: a body 10, a mounting portion 20, and a sealing portion 30.
The mounting portion 20 is connected to the body 10, the mounting portion 20 is suitable for being mounted on the door assembly 200 of the oven 1000, the sealing portion 30 is connected to the body 10, the sealing portion 30 defines the negative pressure groove 31, and when the door assembly 200 closes the cavity assembly 300 of the oven 1000, the sealing portion 30 is pressed against the cavity assembly 300 to seal the negative pressure groove 31 and discharge at least a part of air in the negative pressure groove 31 to form negative pressure.
Specifically, the sealing strip 101 is disposed in a gap between the door assembly 200 and the cavity assembly 300, the mounting portion 20 and the sealing portion 30 are connected to two opposite sides of the body 10, wherein the mounting portion 20 is connected to one side of the body 10 adjacent to the door assembly 200 to enable the mounting portion 20 to be mounted on the door assembly 200, and the sealing portion 30 is connected to one side of the body 10 adjacent to the cavity assembly 300 to enable the sealing portion 30 to be matched with the cavity assembly 300 when the door assembly 200 closes the inner cavity 310 of the cavity assembly 300.
The sealing part 30 is configured with a negative pressure groove 31, the opening direction of the negative pressure groove 31 faces the cavity assembly 300, and in the process of closing the door body assembly 200, as shown in fig. 2, that is, in the process of rotating the door body assembly 200 towards the cavity assembly 300, when the door body assembly 200 rotates until the opening of the negative pressure groove 31 contacts with the cavity assembly 300, as shown in fig. 3, the door body assembly 200 closes the opening of the negative pressure groove 31, and at this time, the volume in the negative pressure groove 31 is V1; the door assembly 200 continues to move towards the cavity assembly 300 to deform the sealing portion 30, as shown in fig. 4, the volume of the negative pressure groove 31 gradually decreases, and since the cavity assembly 300 seals the opening of the negative pressure groove 31, at least a part of air in the negative pressure groove 31 is exhausted, and after the door assembly 200 is completely closed on the cavity assembly 300, the volume of the negative pressure groove 31 is V2 and V2 is less than V1; as shown in fig. 5, the volume of the negative pressure groove 31 is gradually increased by the elastic action of the sealing portion 30, and the volume of the air in the negative pressure groove 31 is increased until the volume in the negative pressure groove 31 is increased to V3, at which time the air pressure in the negative pressure groove 31 is lower than the external atmospheric pressure, and the mounting portion 20 is tightly attached to the chamber assembly 300 under the atmospheric pressure.
According to the sealing member 100 for the oven of the embodiment of the invention, the negative pressure groove 31 is formed on the mounting part 20, and when the door body assembly 200 closes the cavity assembly 300, air in the negative pressure groove 31 is exhausted to form negative pressure, so that the mounting part 20 is tightly fitted to the cavity assembly 300, thus, when the door body assembly 200 is closed to the cavity assembly 300, the sealing part 30 of the sealing strip 101 is not easily separated from the cavity assembly 300, so that a gap between the door body assembly 200 and the cavity assembly 300 is well sealed, and high-temperature steam generated in the cooking process is not easily flowed out from the gap between the door body assembly 200 and the cavity assembly 300; furthermore, for some ovens 1000 with microwave heating function, the sealing member of the embodiment of the present invention can reduce the gap between the door assembly 200 and the cavity assembly 300 and improve the sealing effect between the door assembly 200 and the cavity assembly 300, thereby reducing the possibility of microwave leakage and improving the safety performance of the oven 1000.
Therefore, the sealing member 100 for an oven according to an embodiment of the present invention has advantages of good sealing effect, high safety performance, and the like.
In some embodiments of the present invention, as shown in fig. 1, the sealing portion 30 includes: an inner sealing rim 32 and an outer sealing rim 33. Wherein inner sealing rim 32 extends from body 10 toward cavity assembly 300 and outer sealing rim 33 extends from body 10 toward cavity assembly 300, inner sealing rim 32 being more adjacent to interior cavity 310 of cavity assembly 300 than outer sealing rim 33. The inner sealing edge 32, the outer sealing edge 33 and the body 10 jointly define the negative pressure groove 31, the inner side surface of the outer sealing edge 33 forms the outer side inner wall of the negative pressure groove 31, and the outer side surface of the inner sealing edge 32 forms the inner side inner wall of the negative pressure groove 31. It should be noted that, in the embodiment of the present invention, the inner cavity 310 of the cavity assembly 300 is a cavity defined by the inside of the cavity assembly 300 for placing food to be cooked, and inner and outer means that the inner cavity 310 is closer to the inner side and the outer cavity is farther from the outer side, respectively, with respect to the inner cavity of the cavity assembly 300.
Further, with continued reference to the embodiment shown in FIG. 1, outer seal edge 33 extends obliquely from body 10 toward cavity assembly 300 and away from inner cavity 310 of cavity assembly 300, and inner seal edge 32 extends obliquely from body 10 toward cavity assembly 300 and toward inner cavity 310 of cavity assembly 300. In other words, the outer sealing edge 33 and the inner sealing edge 32 both extend from the body 10 towards the cavity assembly 300 in directions away from each other, and the distance between the outer sealing edge 33 and the inner sealing edge 32 gradually increases in a direction towards the cavity assembly 300, that is, the cross-sectional area of the negative pressure groove 31 gradually increases in a direction towards the cavity assembly 300.
According to some embodiments of the present invention, when the door assembly 200 closes the cavity assembly 300, the inner sealing edge 32 and the outer sealing edge 33 are deformed, so that a portion of the surface of the inner sealing edge 32 facing the outer sealing edge 33 and a portion of the outer sealing edge 33 facing the inner sealing edge 32 are tightly attached to the cavity assembly 300.
Specifically, as shown in fig. 2, the door assembly 200 is hinged to the cavity assembly 300, and during the process that the door assembly 200 pivots towards the cavity assembly 300 to close the inner cavity 310 of the cavity assembly 300, the mounting portion 20 moves towards the cavity assembly 300, the surface of the inner sealing edge 32 facing the outer sealing edge 33 is the outer side surface 32a of the inner sealing edge 32, and the surface of the outer sealing edge 33 facing the inner sealing edge 32 is the inner side surface 33a of the outer sealing edge 33.
As shown in fig. 3, the door assembly 200 rotates to the position where the sealing portion 30 contacts the cavity assembly 300, when the opening of the negative pressure groove 31 abuts against the cavity assembly 300, the end of the inner sealing edge 32 abuts against the cavity assembly 300, and the end of the outer sealing edge 33 abuts against the cavity assembly 300, at this time, the cavity assembly 300 seals the negative pressure groove 31, and the air volume in the negative pressure groove 31 is V1.
As shown in fig. 4, the door assembly 200 continues to rotate towards the cavity assembly 300, the sealing portion 30 deforms, at this time, a portion of the outer side surface 32a of the inner sealing edge 32 is tightly attached to the cavity assembly 300, a portion of the inner side surface 33a of the outer sealing edge 33 is tightly attached to the cavity assembly 300, the sealing portion 30 deforms to change the volume of the negative pressure groove 31, part of air in the negative pressure groove 31 is exhausted, when the door assembly 200 completely closes the inner cavity 310 of the cavity assembly 300, the door assembly 200 is closest to the cavity assembly 300, the deformation of the sealing portion 30 is maximum, the volume of the negative pressure groove 31 is minimum, and at this time, the air volume in the negative pressure groove 31 is V2.
As shown in fig. 5, the sealing portion 30 is deformed by its own elasticity to increase the volume of the negative pressure tank 31, and the volume of the air in the negative pressure tank 31 is increased, so that the pressure of the air in the negative pressure tank 31 is decreased and is lower than the atmospheric pressure of the outside, and the sealing portion 30 is pressed against the chamber assembly 300 by the atmospheric pressure. Therefore, the door body assembly 200 is not easy to separate from the cavity assembly 300 when the door body assembly 200 is closed, so that the potential safety hazard of microwave leakage caused by the fact that the door body assembly 200 is not closed firmly can be avoided; moreover, the inner sealing edge 32 and the outer sealing edge 33 form a double barrier between the door body assembly 200 and the cavity assembly 300, so that high-temperature steam in the cavity assembly 300 is prevented from leaking from a gap between the door body assembly 200 and the cavity assembly 300, a user can be prevented from being scalded by the high-temperature steam in the using process, and the sealing effect is further improved.
In some specific examples of the invention, as shown in FIG. 1, the thickness of both the inner seal rim 32 and the outer seal rim 33 gradually decreases in a direction toward the cavity assembly 300. Thus, when the inner sealing edge 32 and the outer sealing edge 33 deform and cling to the cavity assembly 300, the deformation capability of the inner sealing edge 32 and the outer sealing edge 33 is better, and because the thicknesses of the inner sealing edge 32 and the outer sealing edge 33 are thinner, the gap between the door body assembly 200 and the cavity assembly 300 is smaller, and the sealing effect is better.
Alternatively, with continued reference to the embodiment shown in FIG. 1, the inner sealing rim 32 and the outer sealing rim 33 are connected to each other and the connection is at an inner arc transition within the suction groove 31. Therefore, when the inner sealing edge 32 and the outer sealing edge 33 deform, the elastic deformation effect of the joint of the inner sealing edge and the outer sealing edge is better, and the joint has better structural strength and is not easy to break.
In some embodiments of the present invention, as shown in fig. 1, the cross-section of the mounting portion 20 is configured in a hook shape and the mounting portion 20 defines a mounting groove 21, and an opening of the mounting groove 21 faces outward.
