In a specific implementation, as shown in FIG. 15, the ice exit passage 9 includes a detachable first housing 901 and a second housing 902. The first housing 901 and the second housing 902 have two pairs of buckles. The assembly is assembled to form the assembled side of the ice channel 9. As shown in the figure, a pair of fitting edges 9a can be fastened to each other for connection and fixing, and a pair of fitting edges 9a are realized by a snap structure provided on the two fitting edges during the fastening assembly, and the specific structure of the buckle Reference may be made to some existing designs, which are not specifically expanded here; the assembly side 9b is assembled in the same manner as the assembled side 9a.

In the present embodiment, the

fitting edges

9a and 9b each extend from the edge of the passage inlet 910 toward the edge of the passage outlet 920. The manner in which the ice channels 9 are formed by assembling two separate components is simpler in process; in other words, the ice exit passages 9 are often injection molded, and the integral molding is difficult to manufacture. Of course, in other embodiments of the invention, the ice exit passage 9 is allowed to be integrally formed.

In the embodiment shown in the figure, in order to further reduce the damage to the ice exit passage 9 during the ice block discharge process, and prolong the service life of the ice exit passage 9, the present invention is combined with FIG. 12, FIG. 13, FIG. 15, FIG. The ice-out passage 9 further has a funnel-shaped ice-receiving inner cover 93 integrally formed with the upper and lower through-holes, and the ice-covered inner cover 93 is fitted in the ice receiving portion 91 and coincides with the inner wall of the ice receiving portion 91.

For the entire ice exit channel 9, the most vulnerable location is the area directly below the ice crusher 10, and the addition of the ice cover 93 has the following advantages: reducing the damage after the ice channel 9 is damaged. cost. Specifically, the manufacturing cost of the ice-receiving inner cover 93 is lower than the manufacturing cost of the first housing 901 and the second housing 902 based on the structural shape and size of the component; and the ice inner cover 93 is disposed in the ice receiving portion 91. The side wall is located directly below the ice discharge port 10 of the ice crusher, and is used for directly absorbing the impact of the ice block 10 to discharge the ice block, so as to avoid the ice block directly hitting the ice receiving portion 91, so that the ice crusher is out of the ice channel 9 The damaged component is the ice receiving inner cover 93 instead of the first housing 901 or the second housing 902. Thus, after the ice exit passage 9 is damaged, only the ice receiving inner cover 93 can be replaced, and the maintenance cost can be effectively reduced.

For ease of assembly, the ice-receiving inner cover 93 is fixed to the first housing 901 and the second housing 902 by snapping. Specifically, as shown in FIG. 16 , the first housing 901 and the second housing 902 are respectively provided with at least one through hole 911 at opposite positions on the ice receiving portion 91; in this embodiment, the first housing 901 is The ice receiving portion 91 is provided with two through holes 911. The second housing 902 is also provided with two through holes 911 on the ice receiving portion 91. The two through holes 911 and the second housing on the first housing 901 are provided. The two through holes 911 on the 902 are oppositely disposed. The outer wall of the ice-receiving inner cover 93 protrudes outwardly to form a convex portion 930 which can be embedded in the through hole 911. In the embodiment, the outer peripheral walls of the ice-receiving inner cover 93 are respectively provided with two protrusions 930. The protrusion 930 is embedded in the through hole 911 to fix the ice cover 93 to the inside of the ice receiving portion 91. It is convenient and simple to carry out the snapping by its own structure without using a fixing structure such as other screws, and the assembly efficiency can be improved.

It should be understood that, although the description is described in terms of embodiments, the embodiments are not intended to be construed as a single. The technical solutions in the embodiments may also be combined as appropriate to form other embodiments that can be understood by those skilled in the art.

The series of detailed descriptions set forth above are merely illustrative of the possible embodiments of the present invention, and are not intended to limit the scope of the present invention. Changes are intended to be included within the scope of the invention.
