Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

As shown in fig. 1 and 2, a first embodiment of the present invention provides an exhaust assembly including a housing 10, an exhaust passage 20, and a reinforcing rib 30. Wherein an exhaust channel 20 having an inlet 22 and an outlet and a stiffener 30 are both provided within the housing 10. In the cooking process, gas enters the exhaust channel through the gas inlet 22 and then collides with the channel wall of the exhaust channel to break bubbles, so that gas and liquid separation is realized, liquid falls under the action of gravity, and the gas continues to flow along the exhaust channel and is finally discharged from the gas outlet, so that the problem of pot overflow can be solved. Specifically, the reinforcing ribs 30 are provided in the housing 10, and the reinforcing ribs 30 are connected to both the housing 10 and the exhaust passage 20 to improve structural strength.

By applying the exhaust assembly provided by the embodiment, under the reinforcing effect of the reinforcing ribs 30, the overall structural strength of the exhaust assembly can be improved, especially the structural strength close to the exhaust channel 20, so that the deformation of the exhaust assembly is reduced, and the service life of the exhaust assembly is ensured.

The shape and arrangement mode of the reinforcing ribs can be adjusted according to the size and shape of the shell and the exhaust channel. For example, radial ribs may be arranged on the outer periphery of the exhaust passage, or a plurality of ribs arranged in parallel may be arranged in a direction directed from one side of the casing to the opposite side, or at least two ribs in a concentric circular shape may be arranged on the outer periphery of the exhaust passage. As long as can guarantee that the strengthening rib is connected with casing and exhaust passage simultaneously, can guarantee the structural strength of casing promptly.

As shown in fig. 1 and 2, in the present embodiment, the reinforcing ribs 30 include first reinforcing ribs 31 and second reinforcing ribs 32, the first reinforcing ribs 31 extend in the first direction a, the second reinforcing ribs 32 extend in the second direction B, and the first reinforcing ribs 31 intersect with the second reinforcing ribs 32. Because first strengthening rib 31 and second strengthening rib 32 are all connected with casing and exhaust passage, and first strengthening rib 31 and the crossing setting of second strengthening rib 32, it is better to consolidate the effect, so can further promote the structural strength of casing.

In the present embodiment, the reinforcing ribs 30 include a plurality of first reinforcing ribs 31 and a plurality of second reinforcing ribs 32, and the plurality of first reinforcing ribs 31 intersect with the plurality of second reinforcing ribs 32 to form a net structure, and the net structure is connected to the outer wall of the exhaust passage, so that the structural strength can be further improved.

Specifically, the first reinforcing ribs 31 and the second reinforcing ribs 32 are perpendicular to each other, so that the structural strength of the housing can be improved by using the reinforcing ribs, and the space between the first reinforcing ribs 31 and the second reinforcing ribs 32 can be used for assembling or avoiding components.

Wherein, the interval between two adjacent first strengthening ribs 31 is between 10mm to 50mm, and the interval between two adjacent second strengthening ribs 32 is between 10mm to 50mm, so can guarantee the structural strength of casing, can also be with exhaust assembly's manufacturing cost control in reasonable range. If the distance between two adjacent first reinforcing ribs 31 or two adjacent second reinforcing ribs 32 is smaller than 10mm, on one hand, the production cost of the exhaust assembly is high, and on the other hand, the density of the reinforcing ribs is too large, so that a space for assembling or avoiding components cannot be provided. If the distance between two adjacent first reinforcing ribs 31 or two adjacent second reinforcing ribs 32 is greater than 50mm, the structural strength of the housing cannot be ensured. In this embodiment, the distance between two adjacent first reinforcing ribs 31 or two adjacent second reinforcing ribs 32 is 30mm, so that the material cost can be saved while the strength is ensured.

In this embodiment, the reinforcing ribs 30 are vertically provided on the housing. The casing comprises a bottom plate 11 and an annular side plate 12 which are connected with each other, the annular side plate 12 is arranged around the bottom plate 11, and the exhaust channel 20 and the reinforcing ribs 30 are arranged in a space formed by the bottom plate 11 and the annular side plate 12. Specifically, the reinforcing ribs 30 are connected to both the channel walls of the exhaust channel 20, and the reinforcing ribs 30 are connected to the bottom plate 11 and the annular side plate 12.

As shown in fig. 1, the top surface of the reinforcing bead 30 is lower than the top surface of the exhaust passage 20, so that the reinforcing bead 30 can serve to enhance structural strength without interfering with the assembly of other components.

Specifically, the distance between the top surface of the reinforcing ribs 30 and the top surface of the exhaust passage 20 is between 1mm and 8mm, so that it is possible to prevent foreign matter from being caught on the reinforcing ribs when the housing is assembled, resulting in air leakage of the exhaust passage. Wherein, the distance between the top surface of the reinforcing rib 30 and the top surface of the exhaust passage 20 may be set to a size of 1mm, 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, etc. In the present embodiment, the distance between the top surface of the reinforcing bead 30 and the top surface of the exhaust passage 20 is 5 mm.

In the present embodiment, the ribs 30, the exhaust channel 20 and the housing 10 are made of plastic. Since the inside of the cooking appliance is high in temperature and pressure, the exhaust assembly is expensive if a metal material is used. In order to reduce the cost, the exhaust component is made of plastic materials. The use of plastic material further requires the exhaust assembly to have sufficient structural strength, so it is important to provide the reinforcing rib 30 between the housing 10 and the exhaust passage 20.

As shown in fig. 1, the housing 10 includes a bottom plate 11 and two rib plates 14 disposed on the bottom plate 11 and oppositely arranged, a channel between an inner surface of the two rib plates 14 and an upper surface of the bottom plate 11 forms an exhaust channel 20, and an air inlet 22 of the exhaust channel 20 is disposed at a bottom of the rib plate 14. The structure that the exhaust channel is formed by matching the bottom plate and the rib plate has the advantages of simple structure and convenience in processing, and the processing cost can be reduced. Specifically, the reinforcing ribs 30 are connected to the upper surface of the base plate 11 and the outer wall of the rib plate 14.

As shown in fig. 1, in the present embodiment, the air inlet 22 of the air discharge passage 20 is located on a side wall of the housing 10, and food is not easily introduced into the air discharge passage through the air inlet 22 in the side wall relative to the bottom wall.

As shown in fig. 3 to 5, a second embodiment of the present invention provides a cover assembly, which includes a cover 40 and an exhaust assembly, the exhaust assembly is disposed below the cover 40, and the exhaust assembly is the above-mentioned exhaust assembly. Wherein, the cover body 40 is provided with an exhaust hole, and the exhaust port of the exhaust assembly is communicated with the exhaust hole so as to exhaust the gas from the exhaust hole. The exhaust assembly can effectively improve the structural strength of the device. Therefore, the cover assembly with the structure also has the advantages.
