In a first aspect, the present invention provides a cooking appliance's inner bag subassembly, the inner bag subassembly includes: a liner body configured with a cooking chamber, the liner body including a bottom plate having a drain opening formed thereon; a drain pipe having an inlet connected to the drain port; and a filter section including:

a filter member provided to the drain opening, wherein the filter member includes a body portion having a filter surface facing the cooking chamber, at least a portion of the filter surface having a height higher than a height of a surface of a portion of the bottom plate corresponding to the drain opening, as viewed in a vertical direction;

a restricting member provided to the filtering member, the restricting member being detachably connected to the drain pipe in a state where installation is completed, so as to: by means of which the movement of the filter member is limited.

The utility model provides a liner subassembly, through for filtering component configuration restraint component, and can dismantle the restraint component with the drain pipe and be connected, namely under conventional state, filtering component passes through the relatively stable relation of connection between restraint component and the drain pipe and is restricted the activity, remove when needs take off filtering component to restrain the component with be connected between the drain pipe can, and then can effectively restrain filtering component's activity, reduce the possibility that filtering component breaks away from drain port department by a wide margin, make filtering component can continuously be in the position of outlet and exert filtering capability. In addition, through setting the main part of filter element to the height that the height of its filtering surface's at least partly is higher than the bottom plate and corresponds to the partial surface of outlet, in the in-process of implementing the drainage, ponding that has granular impurity firstly receives the influence of difference in height when flowing through filter element, and partial particulate matter can be intercepted by the edge of the filter element that the height is relatively higher, realizes prefiltering, and partial particulate matter that is not intercepted is further filtered after flowing through filtering surface to promote the filter effect, and convenience of customers clears up corresponding filtration region.

The utility model provides an among the inner bag subassembly, the drain pipe can be riveting, interference fit is connected, welding etc. with being connected of outlet.

In addition, the constraint member is arranged on the filter member, and the constraint member and the filter member can be connected, such as fixed connection or detachable connection, wherein the fixed connection can be bonding, welding and the like, and the detachable connection can be interference fit connection, clamping and the like; the restraining member may be integrally formed with the filter member.

In addition, the connection mode of the detachable connection of the restriction component and the drain pipe can be interference fit connection, clamping connection or combination of the interference fit connection and the clamping connection and the like.

In a specific case where the height of the filter surface of the main body portion is higher than the height of the surface of the bottom plate corresponding to the portion of the drain opening, it may be that the height of a portion of the filter surface is higher than the height of the surface of the bottom plate, or that the height of the entire filter surface is higher than the height of the surface of the bottom plate, for example, the filter surface is formed by a configuration of a flat surface portion and a tapered surface portion, in which the flat surface portion is located at the center of the tapered surface portion, and the filter surface thus configured protrudes entirely from the surface of the bottom plate when the filter member is in a mounted state; alternatively, the filter surface is formed by a planar portion and a plurality of obliquely arranged flat surface portions which are joined to each other and arranged on the periphery of the planar portion to form a cone-like structure, the filter surface thus formed projecting over the surface of the base plate as a whole when the filter member is in the mounted state.

With regard to the above-mentioned liner assembly of a cooking appliance, in some possible embodiments, the filtering surface comprises a curved surface and/or a flat surface and/or a sloping surface.

It will be appreciated that the curved surface may be a cambered or corrugated surface. For example, the filter surface may be formed by a planar portion and a conical portion configuration; or may be formed of a planar portion and a beveled portion configuration; or may be formed by a cambered surface portion and a beveled surface portion; or may consist of just a ramp; or consist of only planes, etc.

With regard to the liner assembly of the cooking appliance described above, in some possible embodiments, the filter member further includes a flanged portion extending downward from an edge of the main body portion, at least a portion of the flanged portion abutting a surface of a portion of the bottom plate corresponding to the drain opening.

Through setting up the turn-ups part, with the surface butt of turn-ups part and bottom plate, through the height of turn-ups part lifting main part's filtering surface to this can reduce main part's thickness, and then reduce its quality, reduction in production cost.

It will be appreciated that, in order to better mount the filter member, the portion of the bottom plate where the drain opening is formed is preferably configured with a counter sink structure, and in this case, the filter member after mounting may be such that only the end face of the flange thereof abuts against the planar portion of the counter sink structure, or may be such that the end face of the flange abuts against the planar portion of the counter sink structure while a portion of the outer peripheral face of the flange abuts against the vertical portion of the counter sink structure, and thus a height difference between the filter surface and the surface of the portion of the bottom plate corresponding to the drain opening is configured by the flange.

With regard to the above-described inner container assembly of the cooking appliance, in some possible embodiments, the main body portion is formed with a first filter portion located at a region of the main body portion near a middle portion thereof.

It will be appreciated that the first filter portion may include one or more first apertures, which may be circular, square, oval, arcuate, or a combination thereof. In the case where the first through-hole includes a plurality of through-holes, it is preferable that the plurality of first through-holes be arranged in a ring-shaped array in a region near the middle thereof.

It will be appreciated that a high filtration capacity indicates that particles in the sump are not readily able to pass through the filter site, and a low filtration capacity indicates that particles in the sump are more readily able to pass through the filter site. In other words, for convenience of understanding, assuming that the directions of the particles are close, the filtering portion with large filtering capacity can fully intercept the particles with small size, while the filtering portion with small filtering capacity can only intercept the particles with large size, and the particles with small size can directly pass through the filtering portion. More specifically, taking the example that the first filtering portion includes a plurality of circular first through holes and the second filtering portion includes a plurality of circular second through holes, the filtering capacity of the second filtering portion is greater than that of the first filtering portion when the aperture of the second through holes is smaller than that of the first through holes.

Thus, a more preferred implementation of the body portion to perform the filtering function is provided. Through setting up the second filtering part to the filter capacity that sets to the second filtering part is greater than the filter capacity of first filtering part, so, the particulate matter in ponding is at first obstructed when passing through the second filtering part in the in-process that accompanies the ponding circulation and stops, and rivers then can further discharge fast through first filtering part, and then accelerate ponding exhaust speed, promote filtration efficiency.
