DETAILED DESCRIPTION

[0017] Hereinafter, the specific implementations of the present disclosure will be further described in detail with reference to the accompanying drawings and embodiments. The following embodiments are used to illustrate the present disclosure, but are not intended to limit the scope thereof.

[0018] It should be noted that, in the description of the present disclosure, the orientation or position relations indicated by the terms "center", "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and etc. are based on the orientation or position relations shown in the drawings, which is merely for the convenience of describing the present disclosure and simplifying the description, and is not to indicate or imply that the device or component referred to must have a specific orientation or be provided and operated in a specific orientation. Therefore, it cannot be construed as limiting the present disclosure.

[0019] In the description of the present disclosure, it should be noted that unless specifically defined or limited, the terms "mounted", "connect to", and "connect with" should be understood in a broad sense, for example, they may be fixed connections, removable connections, or integrated connections; they may be mechanical connections or electrical connections; they may also be direct connections, indirect connections through intermediate mediums, or internal connection of two components. For a person of ordinary skill in the art, the specific meanings of the terms above in the present disclosure can be understood according to specific situations.

[0020] In addition, unless specified otherwise, "multiple", "a plurality of' and "a plurality of sets" means two or more in the description of the present disclosure.

[0021] As shown in Figs. 1-7, the refrigerator air-duct air supply volume adjustable structure provided by the present disclosure includes an air duct plate 1 provided with an air outlet 11, and further including a sliding adjustment plate 2 and a sliding baffle 3.

[0022] As shown in Fig. 1, an inclined slideway 21 is provided on one side of the sliding adjustment plate 2, and correspondingly, the corner above the slideway 21 of the sliding adjustment plate 2 is configured as a slope having the same inclining direction with that of the slideway 21; a poking block 22 protruding outwards is provided on the other side of the sliding adjustment plate 2.

[0023] A pair of sliding chutes 14 vertically opposite to each other are formed in the rear side of the air duct plate 1. The sliding baffle 3 is located in the pair of sliding chutes 14, for limiting the sliding direction of the sliding baffle 3, and a guide pillar 4 is fixedly provided on the side, opposite to the sliding adjustment plate 2, of the sliding baffle 3. The sliding baffle 3 is slidably connected with the slideway 21 by means of the guide pillar 4. In order to prevent the guide pillar 4 from disengaging the slideway 21 during movement, an anti-disengaging structure may be provided at the end portion of the guide pillar 4.

[0024] A poking hole 12 formed in the horizontal direction is provided on the air duct plate 1. The poking block 22 is configured to penetrate out of the poking hole 12, wherein the length of the poking hole 12 is greater than the diameter of the poking block 22, thereby facilitating poking the poking block 22. The sliding adjustment plate 2 is driven to horizontally slide towards to the left and right by poking the poking block 22, so that the sliding baffle 3 slides obliquely along the slideway 21 and slides upwards and downwards along the sliding chutes 14, thus the sliding baffle 3 is driven to slide upwards and downwards along the air outlet 11 to adjust the air outlet volume of the air outlet 11. The adjustment of the air outlet 11 of the present disclosure is completely achieved by the cooperation between mechanically structural members, the advantages of simple structure, low cost and reliable operation are achieved, the air volume of the compartment can be manually controlled, and the selling point is manifested.

[0025] In the embodiments of the present disclosure, as shown in Fig. 1, the slideway 21 is an oblong hole inclined from the bottom to the top from one end of the sliding adjustment plate 2; the guide pillar 4 penetrates out of the oblong hole, and the penetrating end of the guide pillar 4 is engaged by an engaging member to prevent the guide pillar 4 from disengaging the oblong hole, and to ensure that the guide pillar 4 drives the sliding baffle 3 to slide steadily with a suitable length. The engaging member can be a snap spring.

[0026] In the embodiments of the present disclosure, the side facing the air duct plate 1 of the sliding adjustment plate 2 is provided with a snap-fit 23, the end portion of the snap-fit 23 is a tip end or a hook-shaped end. The air duct plate 1 is provided with a plurality of slots disposed at intervals, i.e., corresponding to a plurality of adjustment gears. The arrangement direction of the slots 13 is the moving direction of the sliding adjustment plate 2, and the position limitation is achieved when the snap-fit 23 is clipped into the slots 13, so that when the poking block 22 is poked, the hand feeling of the operator can be enhanced, and the operating gear can be perceived in real time.

[0027] In the embodiments of the present disclosure, three slots 13 are provided corresponding to movement states of the sliding baffle 3 such that the air outlet 11 is fully opened, the air outlet 11 is half opened and the air outlet 11 is fully closed. As shown in Figs. 2-7, in the case that the air outlet 11 is fully closed in Fig. 2 and Fig. 3, the snap-fit 23 stops at the first slot 13. The poking block 22 is pushed towards the right by 20mm, and the guide pillar 4 of the sliding baffle 3 moves upwards along the slideway 21 by 13.5mm, at this time the air outlet 11 is half opened and the snap-fit 23 is pushed to the second slot 13, as shown in Figs. 4 and 5. The poking block 22 is pushed continuously towards the right by 20mm, and the guide pillar 4 of the sliding baffle 3 moves up continuously along the slideway 21 by 13.5mm, so that the air outlet 11 is fully opened and the snap-fit 23 is pushed to the third slot 13, as shown in Fig. 6 and Fig. 7.

[0028] In the embodiments of the present disclosure, in order to facilitate the arrangement of the poking block 22, a concave groove 24 concavely recessed is provided at the position where the poking block 22 is provided on the sliding adjustment plate 2. The concave groove 24 is horizontally arranged, and the poking block 22 is fixedly arranged in the concave groove 24. Specifically, the poking block 22 and the concave groove 24 are integrally formed.

[0029] As shown in Figs. 2, 4 and 6, the poking hole 12 is an oblong hole corresponding to the adjustable length of the poking block 22. The concave groove 24 is disposed opposite to the poking hole 12, and providing the concave groove 24 can reduce the friction between the sliding adjustment plate 2 and the air duct plate 1 when the poking block 22 is poked.

[0030] The present disclosure further provides a refrigerator, including the refrigerator air-duct air supply volume adjustable structure above. The compartment air supply volume of the refrigerator is adjustable, which is convenient in use.

[0031] According to the embodiments above that, the present disclosure provides the size-adjustment of the air outlet by the cooperation between mechanically structural members, and achieves both the manual control of the air inlet volume of the compartment of the refrigerator and the human-machine interaction.

[0032] The descriptions above are only preferred embodiments of the present disclosure, and are not intended to limit the present disclosure. Any modification, equivalent replacement and improvement made within the spirit and principle of the present disclosure shall be within the protection scope of the present disclosure.
