By arranging the sealing ring 600 on the shielding plate 400, when the shielding plate 400 closes the air inlet 310, the sealing ring 600 is extruded between the shielding plate 400 and the air duct cover plate 300, so that the sealing performance between the shielding plate 400 and the air duct cover plate 300 is improved, the air duct and the storage chamber 101 are isolated more effectively, and hot air is prevented from entering the storage chamber 101.
As shown in fig. 12 and 13, the seal ring 600 provided in the embodiment of the present invention includes a sealing portion 610, a connecting portion 620 and a clamping portion 630, the sealing portion 610 is disposed on a surface of the connecting portion 620 facing the air duct cover 300, the sealing portion 610 is disposed on an inner side edge of the connecting portion 620 and extends toward an outer side edge of the connecting portion 620, a cross section of the sealing portion 610 is arc-shaped and a concave surface faces the connecting portion 620, and when the shielding plate 400 closes the air opening 310, the sealing portion 610 is in pressing contact with the air duct cover 300. Through setting up sealing portion 610 to the cambered surface, make have the space between sealing portion 610 and the connecting portion 620, when shielding plate 400 closed tuyere 310, sealing portion 610 is extruded, because there is the space between sealing portion 610 and the connecting portion 620, consequently, sealing portion 610 has great deformation space, be favorable to sealing portion 610 and wind channel apron 300 closely laminating, thereby can improve sealing performance, and sealing portion 610 has the inboard border outside border extension of connecting portion 620, thereby can avoid sealing portion 610 and connecting portion 620 to be located the part department of downside and form the recess, can avoid producing circumstances such as ponding icing.
As shown in fig. 11, 12, and 13, the locking portion 630 is provided on a surface of the connection portion 620 facing the shielding plate 400, a locking hole 450 is provided at an edge of the shielding plate 400, and the locking portion 630 is locked in the locking hole 450. The whole sealing ring 600 is clamped at the clamping hole 450 on the shielding plate 400 through the clamping part 630, so that the sealing ring 600 is convenient to detach, and the sealing ring 600 is convenient to clean or replace.
It should be noted that, the number and positions of the clamping portions 630 and the clamping holes 450 are set in a one-to-one correspondence, so as to ensure that the sealing ring 600 and the shielding plate 400 are clamped to each other.
In some embodiments, because the evaporator can produce condensed water when defrosting, the hot air in the air duct can produce partial condensed water, so that partial condensed water can also be produced in the mounting box 500, and after defrosting is finished, the condensed water in the mounting box 500 is condensed into ice, as shown in fig. 7, 8 and 9, a plurality of drain holes 560 are formed in the bottom surface of the mounting box 500, and the condensed water in the mounting box 500 can be discharged through the drain holes 560, so that water accumulation in the mounting box 500 is avoided, and icing in the mounting box 500 can be avoided.
In some embodiments, to further avoid water accumulation in the mounting box 500, the bottom surface of the mounting box 500 may be inclined at a certain angle, specifically, the structures of the left casing 540 and the right casing 550 are symmetrical to each other, and the left casing 540 is taken as an example for illustration, the portions on the bottom surface of the left casing 540 on two sides of the protrusion are respectively inclined downward, that is, the side close to the protrusion is higher than the side far from the protrusion, so that condensed water in the mounting box 500 is discharged from the edges of the two sides.
In some embodiments, the bottom plate of the mounting box 500 may be integrally provided in an inclined structure, or the bottom surface of the mounting box 500 may be inclined by gradually reducing the thickness of the bottom plate, and thus, the specific structure thereof is not limited in the present application.
In some embodiments, as shown in fig. 7, 8, and 9, a plurality of ventilation holes 570 may be formed in both the side wall and the top surface of the mounting box 500 to increase the air circulation speed inside the mounting box 500, and when the evaporator is defrosted, hot air may be rapidly circulated inside the mounting box 500 to rapidly melt the frost condensed inside the mounting box 500 and drain the condensate through the inclined surfaces on the bottom surface and the drain holes 560.
In some embodiments, in order to make air smoothly flow inside the installation box 500, a certain gap is left between the installation box 500 and the top surface of the liner 110, so that air can enter the inside of the installation box 500 through the vent hole 570 at the top of the installation box 500 and then flow out of the drain hole 560 at the bottom surface of the installation box 500, so that air circulation is smoother, and defrosting efficiency inside the installation box 500 is further improved.
In the description of the present specification, a particular feature, structure, material, or characteristic may be combined in any suitable manner in one or more embodiments or examples.
The foregoing is merely illustrative of the present invention, and the present invention is not limited thereto, and any person skilled in the art will readily recognize that variations or substitutions are within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
