[0002] Panels are an important part of home appliances, cabinets and other home products. In home products, the main function of the panel is to display the operation interface or hide some internal components, such as drawers, working chambers, etc. In traditional home appliances and other home products, the panels are mostly immobile or need to be opened or closed manually. With the popularization of intelligent home products in recent years, home products with immobile or manually opened and closed panels can no longer meet the user's usage requirements.

[0003] Therefore, it is necessary to develop a home product with a panel that can be electrically controlled.

[0004] The electronically controlled action of the panel can not only replace the traditional manual opening and closing method to create a new user experience, but can also be used to match different users or user habits in specific scenarios. For example, the traditional panel is fixed and does not move after the device is installed, but the height and habits of the user in actual use may be different. If the panel has an electronically adjustable function, it can meet the needs of different users. Summary of the invention

[0058] In order to enable those skilled in the art to better understand the present invention, and thus to more clearly define the scope of the present invention, the present invention is described in detail with respect to some specific embodiments of the present invention. It should be noted that the following are only some specific implementation methods of the present invention, which are only part of the embodiments of the present invention, wherein the specific and direct description of the relevant structure is only for the convenience of understanding the present invention, and each specific feature does not naturally and directly limit the scope of implementation of the present invention. The conventional selection and replacement made by those skilled in the art under the guidance of the present invention should be regarded as within the scope of the present invention.

[0059] A base plate device of a household appliance with a movable panel includes a base plate 100 and a panel lifting device arranged on the base plate 100, wherein the panel lifting device is provided with a panel connecting terminal 204 for connecting a panel thereto, so as to realize the motion control of the movable panel of the household appliance, especially the smart household appliance, such as driving and controlling the lifting of the panel.

[0060] The panel lifting device includes two panel lifting mechanisms 200, which are respectively arranged on both sides of the base plate 100, forming a first panel lifting mechanism 201 and a second panel lifting mechanism 202. A transmission shaft 203 is also provided between the first panel lifting mechanism 201 and the second panel lifting mechanism 202, so that the two panel lifting mechanisms 201 and 202 can move synchronously and share the same power mechanism.

[0061] For example, in some embodiments, the panel lifting device further includes two driving mechanisms 220, which are respectively matched with the first panel lifting mechanism 201 and the second panel lifting mechanism 202. The driving mechanism 220 includes a bracket 224 and a driving wheel 222 disposed on the bracket 224, and both ends of the transmission shaft 203 are respectively connected to the driving wheels 222 on the first panel lifting mechanism 201 and the second panel lifting mechanism 202 so that the two rotate synchronously.

[0062] Of course, the rotating shaft 203 may also be omitted, but in this case it may be necessary to configure a power mechanism for each of the two panel lifting mechanisms 201 and 202 .

[0063] The panel lifting mechanism 200 further comprises a panel lifting frame 24 and a displacement mechanism 22. The panel connection end 204 is disposed on the panel lifting frame 24 for connecting the panel thereto. To improve the structural strength, a convex ridge 243 is disposed on the side of the panel lifting frame 24.

[0064] The displacement mechanism 22 is matched with the bottom plate 100 via the reciprocating mechanism 210, so that the displacement mechanism 22 is reciprocatably disposed on the bottom plate 100. The displacement mechanism 22 is provided with a first connection hole 226 and a second connection hole 228, and the panel lifting frame 24 is further provided with a first pivot hole 241 and a second pivot hole 244.

[0065] like Fig. 9 As shown, in order to enable the displacement mechanism 22 to be reciprocally displaced on the bottom plate 100, the reciprocating mechanism 210 includes a guide groove 211 and a guide rail 212, so that the displacement mechanism 22 is reciprocally displaced relative to the guide groove 26. The displacement mechanism 22 includes an angle block 227 and a rack member 225, which are fixedly connected; the rack member 225 is provided with a rack, the first connecting hole 226 is provided on the rack member 225, and the second connecting hole 228 is provided on the angle block 227; the angle block 227 is connected to the reciprocating mechanism 210 to enable the displacement mechanism 22 to be displaced relative to the guide groove 26. A gear matching with the rack is provided on the driving wheel 222, and the driving wheel rotates under the drive of the motor 221, so that the reciprocating displacement direction of the displacement mechanism 22 on the bottom plate 100 can be controlled by controlling the rotation direction of the motor 221. Of course, the displacement speed of the displacement mechanism 22 is related to the rotation speed and speed ratio of the motor 221, which can be specifically set according to needs and is not limited.

[0066] The panel lifting mechanism 200 further includes a first pivoting member 231 , a second pivoting member 232 , and a pivoting link 23 .

[0067] The first pivot member 231 connects the first pivot hole 241 and the first connection hole 226, so that the panel lifting frame 24 and the displacement mechanism 22 can be pivotally matched. The second pivot member 232 connects the second pivot hole 244 and the first end of the pivot link 23, so that the panel lifting frame 24 and the pivot link 23 can be pivotally matched; at this time, the second pivot member 232 and the second pivot hole 244 and the first end of the pivot link 23 are not limited to the matching mode, and it can be fixed with one of the two or can be pivotally matched with both. The second end of the pivot link 23 is pivotally connected to the second connection hole 228, so that the second end of the pivot link 23 can pivot relative to the second connection hole 228.

[0068] When the panel lifting frame 24 pivots around the first pivot member 231, in order to limit the displacement path of the panel connection end 204 at the end of the panel lifting frame 24 so that the panel does not purely exhibit rotational motion, the panel lifting mechanism also includes a guide groove 26, the guide groove 26 includes a lifting guide groove 262 arranged vertically upward or obliquely upward, and the second pivot member 232 is engaged in the lifting guide groove 262; the displacement mechanism 22 is displaced relative to the guide groove 26 to cause the second pivot member 232 to displace along the lifting guide groove 262, and the panel connection end 204 is displaced upward or obliquely upward.

[0069] exist Fig.10 In the embodiment shown, the lifting guide groove 262 is an arc-shaped groove, a horizontal groove 261 is further provided at the proximal end of the lifting guide groove 262, and a horizontal locking groove 263 is provided at the distal end. In addition, the first pivot hole 241 is a strip-shaped groove, and its length is less than or equal to the length of the horizontal groove 261. In this way, the initial displacement of the displacement mechanism 22 does not directly drive the panel to move accordingly.

[0070] In order to facilitate the arrangement of the guide groove 26, the panel lifting mechanism 200 further includes a guide member 25, and the guide groove 26 is arranged on the guide member 25. Figure 6 , 7In the embodiment shown, the guide member 25 includes a first guide member 251 and a second guide member 252. The first guide member 251 is provided with a guide groove 250 and a first guide groove wall 253, and the second guide member 252 is provided with a second guide groove wall 254. The second pivot member 232 includes a guide wheel 233. The first guide groove wall 253 and the second guide groove wall 254 are located on both sides of the guide groove 250 to limit and form a guide groove portion 264 for the guide wheel 233 to cooperate therein, so that in addition to the lifting action of the panel, the displacement of the second pivot member 232 in the left and right directions is also limited so that the panel is not easily offset in the left and right directions. Optimally, in this embodiment, the guide member 25 also includes end blocks 255 arranged at both ends of the guide groove 26 to cooperate with the second pivot member 232 at the two end positions of the displacement.

[0071] Reference Fig.10 , 11 In the initial state, the displacement mechanism 22 is at the rear end position of its reciprocating position path, and the panel is now in a closed state after being matched with the panel connection end 204; the power device, such as the motor 221, works to drive 222 to rotate, and the gear condition 225 is driven to move forward; whether the initial section of the panel lifting frame 24 is horizontally displaced is not limited, but as the displacement mechanism 22 approaches the displacement relative to the guide member 25, the panel lifting frame 24 will pivot around the first pivot member 231, so that the panel at the end of the panel lifting frame 24 moves upward, and the movement of the front end of the panel lifting frame 24 is also limited by the guide groove 26 during the process, for example, Fig.10 In the illustrated embodiment, the second pivot member 232 moves along the arc-shaped lifting guide slot 262 to move the panel upward and forward.

[0072] In addition, although the lifting guide groove 262 is arc-shaped in the above embodiments and the accompanying drawings, it is not necessary to be so. In fact, the guide groove 26 can also be L-shaped as a whole, that is, it is composed of two parts: a horizontal groove and a vertical groove; in this case, the first pivot hole 241 must be a strip groove (in some of the above embodiments, the first pivot hole 241 is not necessarily a strip groove, and it can be a circular groove when the lifting guide groove 262 overlaps with the pivot arc of the panel lifting frame 24). When the panel lifting frame 24 pivots around the first pivot member 231, the first pivot member 231 as a pivot can be displaced in the first pivot hole 241 in the strip groove shape to change the real-time effective length of the panel lifting frame 24, so as to ensure that the second pivot member 232 can move up and down along the vertical groove to achieve the purpose of driving the panel to move up and down.

[0073] Meanwhile, the vertical groove and the arc groove mentioned above may also be provided at the same time, for example, the second pivot member 232 first moves along the arc groove and then moves along the vertical groove.

[0074] In other embodiments, the bottom plate device is further provided with a steam cooling device to cool and safely discharge the steam generated by the device. The steam cooling device includes a steam inlet 301, a fan assembly 32, and an exhaust duct 33. The steam chamber 31 and the fan assembly 32 are arranged in parallel, and the exhaust duct 33 is located on one side of the steam chamber 31. The steam enters the exhaust duct 33 from the steam inlet 301 and mixes with the air pumped in by the fan assembly 32 before being discharged from the exhaust duct 33.

[0075] The exhaust passage 33 includes a first exhaust passage 341, a second exhaust passage 342 and a third exhaust passage 343. The second exhaust passage 342 and the third exhaust passage 343 are formed into a trumpet-shaped exhaust passage with increasing width. The first exhaust passage 341 is connected to the steam inlet 301 and the fan assembly 32, the third exhaust passage 343 is connected to the outside, and the second exhaust passage 342 connects the first exhaust passage 341 and the third exhaust passage 343. One end of the first exhaust passage 341 is connected to the diffusion chamber 321, and the other end is connected to the second exhaust passage 342. The steam inlet 301 is connected to the first exhaust passage 341 through the steam connecting port 314.

[0076] like Fig.16 As shown, the exhaust passage 33 may be formed by the cooperation of a cavity component 331 and a bottom shell 332 , and the first exhaust passage 341 , the second exhaust passage 342 and the third exhaust passage 343 are disposed on the cavity component 331 .

[0077] like Fig.15 , 16 As shown, the depth of the first exhaust channel 341 is greater than the depth of the third exhaust channel 343, and the depth of the second exhaust channel 342 decreases to connect the first exhaust channel 341 and the third exhaust channel 343 respectively.

[0078] A plurality of exhaust ports 303 are formed at the outlet of the exhaust passage 33 . A fixing position 333 is also formed at the outlet of the exhaust passage 33 . The cavity component 331 and the bottom shell 332 at the fixing position 333 are fitted together.

[0079] The fan assembly 32 includes a diffusion chamber 321 and a centrifugal fan blade assembly 322 . The diffusion chamber 321 is provided with an air inlet 302 communicating with the outside, and the first exhaust passage 341 is connected to the diffusion chamber 321 .

[0080] like Fig.19As shown, the steam cooling device further includes a steam cavity 31, which includes a cavity wall 311, a cavity cover 312, and a cavity 313 formed by the cavity wall 311 and the cavity cover 312; the steam inlet 301 is connected to the cavity 313, and the steam communication port 314 is formed by a hollow cavity in a hollow cylindrical guide protruding on the bottom wall of the cavity 313. In addition, a condensation water channel 315 is also provided in the steam cavity 31, and the condensation water channel 315 is provided on the bottom wall of the cavity 313.
