Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.

Referring to fig. 1 and 2, a refrigerator includes a cabinet 100 and a door 200. The cabinet 100 encloses a storage chamber 100a adapted to store food such as fruits and vegetables, and the door 200 is coupled to the cabinet 100 and adapted to move relative to the cabinet 100 to open or close the storage chamber 100 a. The cabinet 100 has a front surface 100b facing the door 200, and the door 200 has a rear surface 200b facing the cabinet 100, and the rear surface 200b is provided with an annular seal strip 200 a. When the door 200 is in the closed state, the annular sealing strip 200a abuts against the front surface 100b to seal the storage chamber 100a and prevent the cold air in the storage chamber 100a from flowing out to the outside.

In this embodiment, referring to fig. 3 to 5 in combination, the accommodating groove 10a is disposed on the front surface 100b, the refrigeration appliance further includes a camera assembly 20 disposed in the accommodating groove 10a, and the camera assembly 20 includes a housing 21 and a camera 22 disposed in the housing 21 and used for shooting. When the door 200 is closed, the camera assembly 20 is received in the receiving groove 10 a; when the door 200 is opened, at least a portion of the camera assembly 20 protrudes out of the receiving groove 10a, so that the camera 22 protrudes out of the receiving groove 10 a.

Since the camera assembly 20 can protrude out of the accommodating groove 10a, that is, the camera 22 can protrude to the front surface 100 b. The camera 22 protruding from the front surface 100b has a relatively better photographing position and photographing angle, and is not easily shielded by the cabinet 100 and the shelf in the storage chamber 100a, so that food in the drawer (not shown in fig. 1) in the opened state in the storage chamber 100a can be more clearly and completely photographed, and food placed on the shelf (not shown in fig. 1) of the door 200 can be more clearly and completely photographed. Through uploading the picture of shooing to high in the clouds for the user can learn the storage condition of food in the refrigeration apparatus through the picture, makes things convenient for the user to formulate cooking plan and purchase plan.

Also, when the door 200 is closed, the camera assembly 20 can be received in the receiving groove 10 a. Therefore, the camera assembly 20 does not affect the opening and closing of the door 200, and does not affect the sealing of the storage compartment 100a in the closed state of the door 200, i.e., does not affect the normal use of the refrigeration appliance.

Note that, the receiving groove 10a may be formed by directly digging on the front surface 100a of the casing 100, or may be defined by a ring-shaped housing 10 fixedly disposed in the casing 100. In this embodiment, the receiving groove 10a is defined by a ring-shaped housing 10 fixedly provided in the casing 100.

In the opened state of the door 200, the camera module 20 protrudes out of the accommodating groove 10a in order to allow the camera 22 to protrude out of the front surface 100b, thereby preventing the housing 100, the shelf, and the like from blocking the image of the camera 22. Therefore, the whole camera assembly 20 can be extended out of the accommodating groove 10a, and a part of the camera assembly 20 can be extended out of the accommodating groove 10a, so that the implementation of the technical scheme is not affected.

Referring to fig. 4 and 5, the refrigeration appliance further includes a push-and-eject mechanism 30 disposed in the receiving groove 10a, and the push-and-eject mechanism 30 is adapted to move in a front-and-rear direction x of the refrigeration appliance to push at least a portion of the camera assembly 20 out of the receiving groove 10a when the door 200 is opened. The elastic pushing mechanism 30 includes an elastic element, specifically a coil spring, which extends along the front-back direction x, one end of the coil spring is connected or abutted to the groove bottom of the accommodating groove 10a, and the other end of the coil spring is connected or abutted to the camera assembly 20.

In this embodiment, one end of the coil spring abuts against the bottom of the accommodating groove 10a, and the other end abuts against the camera module 20. A first accommodating portion 11a for accommodating one end of the coil spring is provided on the groove bottom, and a second accommodating portion 21a for accommodating the other end of the coil spring is provided in the housing 21 of the camera head assembly 20. Both ends of the coil spring are respectively disposed in the first accommodating portion 11a and the second accommodating portion 21a so that the coil spring can be elastically deformed only in the front-rear direction without being displaced in other directions.

When the door 200 is closed, the coil spring is compressed between the groove bottom of the receiving groove 10a and the camera head assembly 20, accumulating elastic potential energy. When the door 200 is opened, the coil spring releases elastic potential energy to push at least a portion of the camera head assembly 20 out of the receiving groove 10 a.

With continued reference to fig. 2, at least a portion of the rear surface 200b is disposed opposite the receiving groove 10 a. When the door 200 is closed, the rear surface 200b disposed opposite to the receiving groove 10a is pressed against the front surface 100b, and the camera assembly 20 is pressed into the receiving groove 10 a. At this time, the coil spring is compressed to accumulate elastic potential energy to push the camera assembly 20 out of the receiving groove 10a when the door 200 is opened next time.

That is, in the refrigeration appliance of the present embodiment, when the door 200 is closed, the door 200 applies a backward urging force to the camera assembly 20 so as to overcome the urging force of the urging mechanism 30, and the camera assembly 20 is accommodated in the accommodation groove 10 a. When the door 200 is opened, at least a portion of the camera assembly 20 is pushed out of the receiving groove 10a by the forward pushing force of the pushing and ejecting mechanism 30 on the camera assembly 20, so that the camera 22 has a better position and angle to more clearly photograph the food in the drawer in the opened state in the storage chamber 100a or to more clearly photograph the food disposed on the shelf of the door.

The above-mentioned manner of controlling the specific position of the camera assembly 20 is relatively simple, does not need to provide a complicated control unit and execution unit, and is completely completed by means of a mechanical structure. In addition, more parts are not needed, the structure is relatively simple, the processing and the manufacturing are easy, and the cost is relatively low.

It should be understood that the urging mechanism 30 functions to urge the camera assembly 20 out of the receiving groove 10a when the door 200 is opened. In this embodiment, a coil spring is used, and in other modifications, other elastic elements such as a rubber spring and a diaphragm spring may be used. It is also possible to mechanically expand and contract the structure to push the camera assembly 20 out of the receiving groove 10 a.

As described above, when the door 200 is closed, the door 200 applies a backward force to the camera assembly 20 to press the camera assembly 20 into the receiving groove 10 a. In this process, a portion of the rear surface 200b disposed opposite to the receiving groove 10a contacts the camera assembly 20 and applies a force to the camera assembly 20. In this embodiment, a portion of the rear surface 200b opposite to the accommodating groove 10a is made of a rubber material or a plastic material, so as to protect the camera assembly 20 and prevent the camera assembly 20 from being damaged due to direct contact with metal parts in the process that the rear surface 200b touches the camera assembly 20.

In other modifications, a rubber sheet or a plastic sheet may be further provided on the rear surface 200b, and when the door 200 is closed, the rubber sheet or the plastic sheet contacts the camera assembly 20 and presses the camera assembly 20 into the accommodating groove 10 a. It is also possible to prevent damage to the camera assembly 20 from direct contact with metal parts.

With continued reference to FIG. 2, a ring-shaped sealing strip 200a is also provided on the rear surface 200b, the ring-shaped sealing strip 200a being adapted to cooperate with the front surface 100b to seal the storage compartment 100 a. When the door 200 is in the closed state, the accommodating groove 10a may be located outside the space surrounded by the annular seal strip 100a or may be located inside the space surrounded by the annular seal strip 100 a. Therefore, it is possible to avoid the annular seal strip 100a being located at a position opposed to the storage chamber 100a, affecting the sealing effect of the annular seal strip 100 a.

In this embodiment, the accommodating groove 10a is located outside the space surrounded by the annular seal strip 100 a.

Referring to fig. 7, the structure of the ring-shaped housing 10 defining the receiving groove 10a is shown. Referring to fig. 8, a perspective structure of the camera assembly 20 is shown. The wall of the accommodating groove 10a is provided with a guide 11b extending along the front-back direction x, the outer wall of the housing 21 in the camera module 20 is provided with a sliding groove 21b extending along the front-back direction x, and the guide 11b is adapted to be disposed in the sliding groove 21b, and is matched with the sliding groove 21b to slide along the sliding groove 21 b. By providing the slide groove 21b and the guide 11b, the sliding direction of the camera assembly 20 is defined, and the camera assembly 20 is prevented from moving in other directions within the accommodation groove 10 a. Meanwhile, the specific position of the camera assembly 20 in the accommodating groove 10a is also defined, and the camera assembly 20 is convenient to slide along the front-back direction x. Specifically, a plurality of guide members 11b are arranged on the groove wall of the accommodating groove 10a, a plurality of sliding grooves 21b are arranged on the outer wall of the housing 21, and the guide members 11b and the sliding grooves 21b are arranged in a one-to-one correspondence manner, so that the camera assembly 20 can be better guided to slide along the front-back direction x.

The cooperation of the guide 11b and the slide groove 21b enables the camera assembly 20 to slide in the front-rear direction x. Therefore, the outer case 21 of the camera head assembly 20 can be in clearance fit with the groove wall of the receiving groove 10a, so that the camera head assembly 20 can more easily slide in the receiving groove 10 a.

With continuing reference to fig. 7 and 8 and with combined reference to fig. 6, a limiting groove 11c is further formed in a groove wall of the accommodating groove 10a, a limiting block 21c is further formed in an outer wall of the housing 21 in the camera assembly 20, the limiting block 21c is located in the limiting groove 11c, and the limiting groove 11c is used for limiting the distance that the camera assembly 20 extends out of the accommodating groove 10a along the front-back direction x, so that a relatively proper distance is formed between the camera 22 and the front surface 100b, and the food in the drawer in the open state can be shot clearly and completely, or the food arranged on the shelf of the door can be shot clearly and completely. Meanwhile, the camera assembly 20 can be prevented from being detached from the receiving groove 10 a.
