For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0042] The sealing structure provided by the utility model can be applied to, but not limited to, dishwashers, and can also be applied to other electrical appliances, such as steam ovens.
[0043] like Figure 8 As shown, the sealing structure is connected to the cavity, and the sealing structure includes: a sealing sheet 110, and the sealing sheet 110 can be connected to the cavity by a mounting piece, and can also be connected to the cavity by gluing.
[0044] like Figure 1 - Figure 7 As shown, the sealing sheet 110 is installed at the gap between the transverse end surface of the door lining sealing strip 310 and the side wall of the cavity. Specifically, in this embodiment, the cavity includes an inner liner 210 and a hinge fixing member 220 located outside the inner liner 210, as shown in FIG. Figure 2 and Figure 7 As shown, the hinge fixing member 220 is used to connect with the door body to realize the flipping of the door body. The sealing sheet 110 is connected with the cavity through the mounting seat 120. Specifically, the mounting seat 120 is inserted into the gap between the inner liner 210 and the hinge fixing member 220, and the sealing sheet 110 is fixedly connected with the mounting seat 120.
[0045] like Figure 7 As shown, taking the left sealing sheet 110 as an example, when the door body is closed, the right side of the sealing sheet 110 abuts against the lateral end face of the door lining sealing strip 310. The rear edge of the sealing sheet 110 abuts against the front face of the door sealing strip 320. The lower edge of the sealing sheet 110 abuts against the bottom face of the liner 210. The sealing sheet 110 is elastic and can be deformed under compression, thereby making the fit more tight.
[0046] like Fig.11 As shown, if the sealing sheet 110 is not provided, the steam in the inner pot 210 will first flow to the left, and then move forward, thereby flowing out of the inner pot 210. In this embodiment, when the door is closed, the rear edge of the sealing sheet 110 abuts against the door sealing strip 320, and the lower edge abuts against the bottom surface of the cavity, preventing the steam from flowing laterally toward the inner wall of the cavity; and because the sealing sheet 110 abuts against the lateral end surface of the door lining sealing strip 310, the steam is prevented from flowing forward out of the cavity from the gap, thereby improving the sealing performance of the cavity.
[0047] like Fig.11 As shown, in order to avoid interference between the door liner sealing strip 310 and the sealing sheet 110, which would hinder the opening and closing of the door body, there is a deformation gap between the sealing sheet 110 and the cavity in the horizontal direction, that is, when the door body is closed, the door liner sealing strip 310 abuts against the sealing sheet 110, and the sealing sheet 110 tilts toward the inner wall of the liner 210 to avoid entanglement and interference.
[0048] The sealing member provided by the utility model comprises a mounting seat 120 and the above-mentioned sealing structure, the sealing structure and the mounting seat 120 are connected, and the mounting seat 120 is used to be connected to the cavity.
[0049] In this embodiment, the cavity includes an inner liner 210 and a hinge fixing member 220 located outside the inner liner 210. The hinge fixing member 220 is used to connect with the door body. The hinge fixing members 220 on both sides are located on the left and right sides of the outer side of the inner liner 210 to achieve the flipping of the door body. The sealing sheet 110 is connected to the cavity through the mounting member. Specifically, the mounting seat 120 is inserted into the gap between the inner liner 210 and the hinge fixing member 220, and the sealing sheet 110 is fixedly connected to the mounting seat 120.
[0050] like Figure 8 As shown, the seal can be directly processed on the mounting seat 120 by injection molding, which has higher structural stability than gluing. Of course, the two can also be connected by other conventional mechanical connection methods.
[0051] The connection position between the sealing member and the mounting seat 120 is higher than the lowest water level of the inner tank 210, thereby preventing the connection from being soaked in water and increasing the service life.
[0052] like Fig. 9 and Fig.10 As shown, the inner liner 210 and the hinge fixing member 220 have a gap in the lateral direction, and the back of the mounting seat 120 has an inserting portion 121 embedded in the gap between the inner liner 210 and the hinge fixing member 220. The width of the inserting portion 121 is substantially the same as the width of the gap, and the number of the inserting portions 121 along the up and down directions may be more than one. After the inserting portion 121 is inserted into the gap, the mounting seat 120 can be fixed by relying on the clamping force between the inner liner 210 and the hinge fixing member 220, thereby preventing the mounting seat 120 from moving in the left and right directions relative to the cavity.
[0053] Further, such as Fig.10 As shown, a buckle 122 is provided on the back of the mounting seat 120, and a hole 221 that docks with the buckle 122 is provided on the hinge fixing member 220. When the plug-in portion 121 is plugged in, the buckle 122 docks with the hole 221. The buckle 122 is used to prevent the plug-in portion 121 from detaching from the gap between the inner liner 210 and the hinge fixing member 220, thereby preventing the mounting seat 120 from falling off.
[0054] In the left and right directions, Figure 2 As shown, the distance between the inner wall of the inner container 210 and the outer wall of the hinge fixing member 220 is smaller than the length of the mounting seat 120 in the left-right direction, so that the mounting seat 120 completely covers the front edges of the inner container 210 and the hinge fixing member 220. The inner container 210 and the hinge fixing member 220 are both metal parts, and burrs will be left during processing. The plate surface of the mounting seat 120 located outside the gap completely covers the front edges of the inner container 210 and the hinge fixing member 220 to prevent users from scratching their hands when taking down the shelf.
[0055] like Figure 3As shown, the inner liner 210 has a flange 211 folded outward, and the flange 211 is located above the mounting seat 120; the top of the mounting seat 120 has a limiting plate 123 extending upward, and the limiting plate 123 is inserted behind the flange 211. The limiting edge is clamped between the flange 211 and the hinge fixing member 220 to prevent the mounting seat 120 from moving in the front and rear directions, thereby further improving the connection stability of the mounting seat 120.
[0056] like Figure 2 As shown, there is a height difference between the front edge of the hinge fixing 220 and the front edge of the inner liner 210, and a protrusion 124 protruding toward the rear side is provided on the back side of the mounting base 120, and the protrusion 124 abuts against the edge of the hinge fixing 220 to compensate for the height difference between the edge of the hinge fixing 220 and the edge of the inner liner 210, thereby preventing the mounting base 120 from tilting when connected.
[0057] The dishwasher provided by the utility model comprises the above sealing structure or the above sealing member, and has the advantages of the above sealing structure or the above sealing member.
[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
