It can be understood that the transparent cover 121 can be regarded as a part of the corresponding functional module.

Furthermore, a heating wire (not shown) is provided on the inner periphery of the transparent cover 121 to heat the transparent cover 121 to prevent condensation on the transparent cover 121 .

Further, the window 111 has two long sides in the same axial extension direction of the mounting bracket 12 , and the display module 1 also includes two long sides respectively located at the two long sides and facing the storage box 11 Two rubber strips 122 protrude inward. One end of the rubber strips 122 faces the mounting bracket 12 and is close to the outer peripheral surface of the mounting bracket 12 . During the rotation of the mounting bracket 12 , the rubber strips 122 The strips 122 scrape off the condensation on the surface of the transparent cover 121 to achieve the dew removal effect.

Specifically, the mounting bracket 12 is hollow inside, and the mounting port connects the inside and outside of the mounting bracket 12, so that the connecting wires of each functional module can be routed through the mounting bracket 12, simplifying the display module. 1 internal structure.

Specifically, the opposite ends of the mounting bracket 12 are respectively provided with rotating shafts 123, and the receiving box 11 is provided with a mounting plate 114. The mounting plate 114 has an axis hole that matches the rotating shaft 123. The rotating shafts 123 of the frame 12 are respectively assembled into corresponding shaft holes, so that the mounting frame 12 and the storage box 11 can be assembled together.

Further, the rotating shaft 123 is hollow, and the two ends of the box 112 corresponding to the rotating shaft 123 have wiring holes 1121 respectively. The wiring of each functional module passes through the inside of the mounting bracket 12 and the rotating shaft 123 in sequence. , lead out the wiring hole 1121.

It can be understood that after the display module 1 is installed on the inner pot 21, 3M tape can be pasted on the wiring hole 1121 to seal the wiring hole 1121, so that the wiring hole 1121 can be sealed during the foaming process. , the foam material cannot flow into the storage box 11 from the wiring hole 1121 .

After the driving assembly 13 is started, the output shaft rotates, and the meshed first gear 132 and the second gear 133 drive the rotating shaft 123 to rotate, thereby causing the mounting bracket 12 to rotate. Turn.

Further, the projection module includes a projection device and a camera device. After opening the door, first control the mounting bracket 12 to rotate until the projection module corresponds to the window 111. The camera device can recognize the user's gestures or obtain the user's gestures. The time the arm is in the projection area is used to determine whether the projection equipment needs to be started.

At the same time, after starting the projection device to project the interface to the projection area, the camera device can obtain the interface of the projection area and determine whether there is condensation based on whether the interface is blurred.

It can be understood that the projection module, lighting module and sterilization module are all located in the refrigeration compartment 2 and are in the same environment. Therefore, if there is condensation on the surface of the transparent cover 121 corresponding to the projection module, it will not be the same as the lighting module, There is condensation on the surface of the transparent cover 121 corresponding to the sterilization module.

In a specific embodiment, the sterilization module is an ultraviolet sterilization module, but of course, it is not limited to this.

Referring to Figure 6, the control method of the refrigeration device 100 in the present invention includes the following steps:

Obtain the door opening signal and control the mounting bracket 12 to rotate until the projection module is exposed from the window 111;

Determine whether the projection module needs to be started. If yes, start the projection module; if not, control the mounting bracket 12 to rotate until the lighting module is exposed from the window 111 and then start the lighting module.

In a specific implementation, "determining whether the projection module needs to be started" specifically includes the following steps:

It is identified whether the user's arm stays in the projection area corresponding to the window 111 for more than the first preset time. If so, it is judged that the projection module needs to be started; if not, it is judged that the projection module does not need to be started.

Specifically, the user's arm is identified through the camera device and the dwell time of the user's arm is accumulated. If the dwell time of the user's arm in the projection area exceeds the first preset time, it indicates that the user needs a touch operation, that is, the projection module needs to be started. ; If the user's arm stays in the projection area for less than the first preset time, it means that the user is only picking up and placing items without starting the projection module.

Specifically, the preset time is 10S.

In another specific implementation, "determining whether the projection module needs to be started" specifically includes the following steps:

Recognize the user's gesture action. If the gesture action is a preset gesture action, it is determined that the projection module needs to be activated; if the gesture action is different from the preset gesture action, it is determined that the projection module does not need to be activated.

Specifically, the user's gesture actions are acquired through the camera device and fed back to the controller. The controller compares the acquired gesture actions with the pre-stored gesture actions. If the two are the same, it determines that the user needs a touch operation, that is, the projection module needs to be started; If the two are different, there is no need to start the projection module.

Further, after starting the projection module, the control method also includes a condensation determination step of determining whether there is condensation on the surface of the projection module:

Get the interface projected by the projection module to the projection area;

Determine whether the interface is blurred. If so, it means there is condensation; if not, it means there is no condensation.

It can be understood that the surface of the projection module refers to the surface of the transparent cover corresponding to the projection module.

Specifically, the interface projected by the projection device into the projection area is obtained through the camera device and fed back to the controller. The controller determines whether there is condensation based on the clarity of the fed back interface.

It can be understood that if the interface is blurred, it means there is condensation on the transparent cover; if the interface is clear, it means there is no condensation on the transparent cover, and the user can directly touch the interface in the projection area.

Further, after it is determined that there is condensation, the control method also includes a dew removal step of removing condensation:

The mounting bracket 12 is controlled to rotate n times.

During the rotation of the mounting bracket 12, the rubber strip scrapes off the condensation on the surface of the transparent cover to achieve the dew removal effect.

During one rotation of the mounting bracket 12 , the adhesive strips can sequentially scrape off condensation on the transparent covers corresponding to the projection module, lighting module, and sterilization module to achieve the dew removal effect.

Specifically, "controlling the mounting bracket 12 to rotate n times" specifically includes the following steps: controlling the mounting bracket 12 to alternately rotate forward and reverse.

By controlling the mounting bracket 12 to alternately rotate forward and reversely, the connecting wires of each functional module can be prevented from being tangled and disordered.

In a specific implementation, n=3, that is, the mounting bracket 12 is controlled to rotate forward and reverse alternately for a total of 3 rotations to scrape off the condensation on the transparent covers corresponding to the multiple functional modules. .

Further, after "controlling the mounting frame 12 to rotate n times", the control method also includes the following steps: controlling the activation of heating wires corresponding to the projection module, lighting module and sterilization module.

That is, controlling the activation of the heating wires on the transparent covers corresponding to the projection module, lighting module and sterilization module can heat the corresponding transparent covers and increase the temperature of the transparent covers, thereby preventing condensation on the transparent covers.

Specifically, the heating wire can be controlled for a preset time, or the heating time of the heating wire can be controlled by sensing the temperature of the transparent cover, as long as the purpose of preventing condensation on the transparent cover can be achieved.

After "controlling the activation of the heating wires corresponding to the projection module, lighting module and sterilization module", the user can directly perform touch operations on the interface of the projection area.

At the same time, after the user's touch operation is completed, the installation frame 12 is controlled to rotate until the lighting module is exposed from the window 111 and the lighting module is started to light up the refrigeration compartment 2 to facilitate the user to pick up and place items.

Further, after the user completes picking up and placing items, that is, after "controlling the mounting bracket 12 to rotate until the lighting module is exposed from the window 111 and starting the lighting module," the control method also includes the following steps:

Get the door closing signal;

After closing the door, the control mounting frame 12 rotates until the sterilization module corresponds to the window 111 and then controls the sterilization module to start every second preset time.

After closing the door, the sterilization module is controlled to start intermittently for sterilization, which can reduce bacteria in the refrigeration compartment 2 and enhance the freshness preservation effect.

In a specific implementation, the second preset time is 15 minutes, but of course, it is not limited to this.

In summary, in the control method of the refrigeration device of the present invention, only one functional module can be controlled to be exposed from the window at a time, which can reduce interference between functional modules. After opening the door, the projection module is first controlled to be exposed from the window, which is convenient for users. Touch operation increases the convenience of interaction and improves the user experience.
