[0047] The technical solution of the present utility model will be further specifically described below through embodiments in conjunction with the drawings. In the description, the same or similar reference numerals indicate the same or similar components. The description of the embodiments of the present utility model with reference to the drawings is intended to explain the overall inventive concept of the present utility model and should not be construed as a limitation of the present utility model.

[0048] See Figure 1 and Figure 2 , showing a partial perspective structural view of a kitchen appliance 100 according to an embodiment of the present utility model. Figure 1 The structure shown is provided with a housing part, Figure 2 The housing is removed from the structure shown, making it easier to see its internal structure.

[0049] The kitchen appliance 100 can be, for example, an electric steam box, an electric oven, an air fryer, or a steam oven combination, etc., which require the generation of steam during use.

[0050] The kitchen appliance 100 includes a body 10, a water tank 20, and an operation panel 30. In addition, the kitchen appliance 100 further includes a driving device for driving the operation panel. The driving device mainly includes two main mechanisms such as a motor assembly 40 and a moving assembly 50. That is to say, when the device has at least the body 10, the water tank 20, and the operation panel 30, the device should be considered as the kitchen appliance 100 in the present utility model.

[0051] The kitchen appliance 100 can be used for household use, or for restaurants, hotels, factories, enterprises, transportation vehicles, etc. The specific usage locations and scenarios are not limited.

[0052] As shown in the figure, an operation panel 30 is provided at the upper end of the front side of the body 10. Correspondingly, a door for opening the kitchen appliance 100 is mainly provided at the lower end of the front side of the body 10 for placing food to be cooked. Generally, in one embodiment, the motor assembly 40 and the moving assembly 50 are provided on the upper surface of the body 10. For example, existing electric steamers or steam convection ovens or steam ovens usually arrange an air duct fixing plate and an air duct cover plate (which can also be simply referred to as a steam condensation assembly) on the upper surface of the body 10. Therefore, the water tank shell can be fixedly provided on the air duct fixing plate or the air duct cover plate. During use, the water tank 20 is slidably arranged in the water tank shell in a pull-out manner.

[0053] That is, when water needs to be added to the water tank 20, the operation panel 30 is moved outwards or up and down to expose the water tank 20, so that the user can pull it out and remove it from the water tank shell. Vice versa, after the water tank 20 is filled with water, the water tank 20 is re-placed in the water tank shell, and the operation panel 30 is moved in the reverse direction to return it to its original position. At this time, the operation panel 30 completely covers the water tank 20, making the whole appliance more beautiful.

[0054] As described above, the driving device is mainly used to drive the operation panel 30 to move away from the shell of the kitchen appliance 100 when the water tank 20 is taken out of the kitchen appliance 100, so as to facilitate the water addition operation. Of course, the driving device can also move the operation panel 30 in the reverse direction to reset it.

[0055] In one embodiment, the moving assembly 50 is respectively connected to the motor assembly 40 and the operation panel 30, and the motor assembly 40 drives the moving assembly 50 to move forward and backward and / or up and down to drive the operation panel 30 to move away from or move closer to the shell of the kitchen appliance 100, wherein the moving assembly 50 moves the operation panel 30 up and down through any one of a rolling bearing or a sliding bearing and / or moves the operation panel 30 forward and backward through any one of a sliding bearing or a rolling bearing.

[0056] The inventors of this patent can make the structure of the driving device simpler and the movement smoother by setting rolling bearings and / or sliding bearings to perform the up-and-down movement and front-and-back movement of the operation panel 30 respectively, and can make both ends of the operation panel move simultaneously without getting stuck. Since the resistance of the up-and-down movement is greater, in this patent, it is preferably to use rolling bearings to roll in the lifting track to realize the up-and-down movement of the operation panel 30, and use rolling bearings to roll and move in the straight chute, making the front-and-back movement and up-and-down movement of the operation panel 30 more stable and smooth, without getting stuck or damaged, and greatly reducing the noise generated by the up-and-down sliding during work.

[0057] How to set up each component of the moving assembly and the motor assembly to achieve the above-mentioned moving operation will be described in detail below.

[0058] See Figure 3 , the moving assembly 50 includes a left fixing seat 51 and a right fixing seat 52 respectively fixed on both sides of the body 10 of the kitchen appliance 100;

[0059] Chute grooves 53 are respectively arranged on the inner side surfaces of the left fixing seat 51 and the right fixing seat 52. Generally, the left fixing seat 51 and the right fixing seat 52 can be arranged at one end of the body 10 away from the operation panel 30 (such as the left end shown in the figure). Of course, those skilled in the art can set their positions as needed, not limited to the form shown in this patent.

[0060] Furthermore, the moving assembly 50 further includes: a left lifting track seat 54 and a right lifting track seat 55 respectively located in front of the left fixing seat 51 and the right fixing seat 52 (close to the operation panel 30);

[0061] A left support frame 56 and a right support frame 57 respectively connected to the operation panel 30.

[0062] The tracks of the left lifting track seat 54 and the right lifting track seat 55 are arranged as a first horizontal section, a second inclined section and a third horizontal section connected in sequence in the direction towards the operation panel 30, the height of the third horizontal section is higher than the height of the first horizontal section, and the inclination angle of the second inclined section is 30 - 60 degrees.

[0063] The motor assembly 40 includes a left horizontal moving bearing 41 and a right horizontal moving bearing 42 respectively used for horizontal movement in the chute grooves 53 of the left fixing seat 51 and the right fixing seat 52 (see Figure 3 and Figure 4 shown), wherein the motor assembly 40 drives the moving assembly 50 to move by the sliding of the left horizontal moving bearing 41 and the right horizontal moving bearing 42 in the chute grooves 53.

[0064] In one embodiment, the motor assembly 40 further includes:

[0065] The electric push rod motor 43 is disposed on the upper surface of the steam condensation assembly (such as the air duct cover plate and the air duct fixing plate) of the kitchen appliance 100 and near the first end (such as the left end shown in the figure) of the operation panel 30;

[0066] The electric push rod 44 is connected to the electric push rod motor 43, is disposed on the upper surface of the steam condensation assembly and extends from the first end to the second end (such as the right end shown in the figure) opposite to the first end;

[0067] The electric push rod bracket 45 is movably disposed on the electric push rod 44, and both ends of the electric push rod bracket 45 are fixedly connected to the left horizontal moving bearing 41 and the right horizontal moving bearing 42 respectively.

[0068] Combined Figure 3 and refer to Figure 5 , a form of the chute 53 can be set as a blind groove on the inner side surface. In this structural setting form, the sliding or rolling parts of the left horizontal moving bearing 41 and the right horizontal moving bearing 42 are installed in the chute 53 and slide or roll under the drive of the motor assembly 40. As shown in the figure, the chute 53 is a blind groove, that is, only on the inner side surface, without penetrating the entire left fixing seat 51 and right fixing seat 52.

[0069] Refer to Figure 6 , the chute 53 can also be set to include a groove 531 for accommodating the left horizontal moving bearing 41 or the right horizontal moving bearing 42 arranged along the longitudinal direction (i.e., the left - right direction shown in the figure) of the blind groove.

[0070] Refer to Figures 7a - 7d , both the left horizontal moving bearing 41 and the right horizontal moving bearing 42 include a bearing cylinder 46 and a shaft rod 47 passing through the bearing cylinder.

[0071] In use, the bearing cylinder 46 abuts and rolls or slides in the chute 53 or the groove 531, and one end of the shaft rod 47 passes through the bearing cylinder 46 (such as the through - hole therein), the left support frame 56 or the right support frame 57 of the moving assembly 50 (such as the perforation thereon) and is fixedly connected to the electric push rod bracket 45. In this way, the left support frame 56 and the right support frame 57 can be fixedly connected to both ends of the electric push rod bracket 45 through the left horizontal moving bearing 41 and the right horizontal moving bearing 42 respectively, and the left support frame 56 and the right support frame 57 can be driven to move synchronously by the movement of the electric push rod bracket 57 by means of the sliding or rolling of the left horizontal moving bearing 41 and the right horizontal moving bearing 42 in the chute 53.

[0072] Return to refer to Figure 5, in the case where the groove 531 is not provided, the bearing cylinder 46 slides or rolls on the smooth surface of the chute 53, so as to ensure that during the sliding or rolling process, the bearing cylinders 46 on the left and right sides will not shake left and right, and can slide or roll synchronously one after another. However, in the case where the groove 531 is provided, the bearing cylinder 46 is completely accommodated in the groove 531, which can better ensure that during the sliding or rolling process, the bearing cylinders 46 on the left and right sides will not shake left and right, and can slide or roll synchronously one after another. Of course, some lubricating oil can also be provided in the groove 531 to make the sliding or rolling smoother.

[0073] As Figure 6 shown, the moving assembly 50 further includes: slideways 532 respectively arranged on the outer side surfaces of the left fixed seat 51 and the right fixed seat 52 and correspondingly arranged with the chute 53;

[0074] See Figures 7a - 7d , a shaft cap is arranged at the other end of the shaft rod 47, and the diameter of the shaft cap is larger than the width of the slideway 532 and is movably sleeved outside the slideway 532. In this way, when the shaft rod 47 passes through the bearing cylinder 46 and the left fixed seat 51 or the right fixed seat 52 from the outer side and is fixedly connected to the electric push rod frame 45, a shaft cap is arranged at one end of the shaft rod 47 located on the outer side, and the shaft cap is clamped or sleeved on the outer side, that is, it plays a role in fixing one end of the shaft rod 47 located on the outer side, and also allows the shaft rod 47 to move along the slideway 532.

[0075] It can be understood that the depth of the chute 53 is greater than the depth of the slideway 532; the width of the chute 53 is greater than the width of the slideway 532; the length of the chute 53 is greater than the length of the slideway 532, so that the size of the bearing cylinder 46 can be set larger, ensuring smoother rolling or sliding in the chute 53. The lengths of the chute 53 and the slideway 532 can be designed according to actual needs respectively, and as long as the length of the chute 53 is greater than the length of the slideway 532, the specific difference in size can be determined according to actual needs.

[0076] The widths of the chute 53 and the slideway 532 can be designed according to actual needs respectively, and as long as the width of the chute 53 is greater than the width of the slideway 532, the specific difference in size can be determined according to actual needs.

[0077] See Figures 8a - 8d shown, one end of the shaft rod 47 passes through the slideway 532, the bearing cylinder 46, the left support frame 56 or the right support frame 57 of the motor assembly 40 and is fixedly connected to the electric push rod frame 45 through the thread on the shaft rod 47, and the diameter of the other end of the shaft rod 47 is larger than the width of the slideway 532 and is movably sleeved outside the slideway 532 (specifically see Figure 2as shown).

[0078] Specifically, the shaft rod 47 and the bearing cylinder 46 are arranged in two parts, and the thread is provided at one end of the shaft rod 47. The shaft rod 47 is fixedly connected to the electric push rod frame 45 through this thread.

[0079] In some embodiments, both the left lifting and moving bearing 58 and the right lifting and moving bearing 59 are rolling bearings or sliding bearings.

[0080] In some embodiments, both the left horizontal moving bearing 41 and the right horizontal moving bearing 42 are rolling bearings or sliding bearings.

[0081] Combining the structural features described in the above various embodiments, the working principle of the driving device of this patent is as follows:

[0082] In the normal working state, the operation panel 30 is closed to the body 10, thereby completely covering the water tank 20 provided behind it. When water needs to be added to the water tank 20, the electric push rod motor 43 is started, and it drives the screw rod inside the electric push rod 44 to rotate. The rotation of this screw rod drives the electric push rod frame 45 to move, so that the electric push rod frame 45 makes a horizontal movement towards the operation panel 30. The electric push rod frame 45 horizontally slides or rolls in the chute 53 through the left horizontal moving bearing 41 and the right horizontal moving bearing 42 connected thereto, so as to drive the operation panel 30 to move horizontally through the left support frame 56 and the right support frame 57 fixedly connected to them.

[0083] Of course, if it is necessary for the operation panel 30 to be able to move up and down while making the above horizontal movement, then the left lifting and moving bearing 58 and the right lifting and moving bearing 59 provided on the left support frame 56 and the right support frame 57 move along the tracks in the left lifting track seat 54 and the right lifting track seat 55. The track is set as a first horizontal section, a second inclined section, and a third horizontal section that are sequentially connected in the direction towards the operation panel. The height of the third horizontal section is higher than the height of the first horizontal section. During the movement, the operation panel 30 can be gradually moved upward. It can be understood that the operation panel 30 can be moved downward by adjusting the direction of the track. When moving to the rightmost position along the track, the movement stops, so that the operation panel 30 has completely exposed the water tank 20 through the movement, and thus the water tank 20 can be taken out for adding water.

[0084] When the water addition to the water tank 20 is completed and it is placed back into the water tank shell, the electric push rod motor 43 can be started again, so that it moves in the reverse direction, thereby resetting the operation panel 30. The specific process will not be elaborated here.

[0085] The driving device for driving the operation panel of the kitchen appliance according to the embodiment of the present invention has at least one or a part of at least one of the following advantages:

[0086] The driving device for the operation panel of a kitchen appliance provided by this patent realizes the forward and backward movement and / or up and down movement of the operation panel by using rolling bearings and sliding bearings alone or in combination, so that the movement of the operation panel is more stable and smooth, without causing jamming or necrosis, and also greatly reduces the noise generated by lifting and sliding during operation.

[0087] Although some embodiments of this general inventive concept have been shown and described, those of ordinary skill in the art will understand that changes can be made to these embodiments without departing from the principles and spirit of this general inventive concept. The scope of this utility model is defined by the claims and their equivalents.
