Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to a drawer-type cooking appliance. Background Technology

[0002] Cooking appliances, such as electric ovens and microwave ovens, are equipped with a cooking cavity and a door assembly. After cooking, users open the door assembly and reach into the cooking cavity to remove the heated food. However, since the door assembly of existing cooking appliances is mostly located on the front and is hinged to the cooking cavity, users need to hold the food and move it horizontally a certain distance before reaching it out, making it inconvenient. Furthermore, if the temperature inside the cooking cavity is high, users may suffer burns when reaching inside, negatively impacting the user experience.

[0003] Drawer-type cooking appliances allow food to be pulled out of the cooking cavity along with the drawer, making it easy for users to take out the cooked food directly from the drawer. Due to their convenience, drawer-type cooking appliances have gradually begun to dominate the market.

[0004] In drawer-type cooking appliances, the drawer inevitably wobbles from side to side during the pulling and pulling process. To address this, existing technologies often incorporate multiple sets of rollers with different rolling axes, especially vertically oriented rollers. This ensures smooth drawer operation while also limiting the drawer's movement in the lateral direction. However, this structural design also makes the drawer's movement-related components more complex, increasing the difficulty of assembling the drawer within the cooking cavity. Utility Model Content

[0005] In view of this, the present invention aims to propose a drawer-type cooking appliance to solve the problem that the structure related to movement on the drawer in the prior art is relatively complex, which makes the assembly of the drawer in the cooking cavity difficult.

[0006] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0007] A drawer-type cooking appliance includes a cavity and a drawer. The cavity has a cooking chamber inside, and the drawer is connected to the cavity in a manner that allows it to move back and forth within the cooking chamber. The bottom wall of the cavity is provided with a sliding groove extending in the front-back direction, and the bottom of the drawer is provided with a roller. The rotation center axis of the roller is arranged in the left-right direction, and the roller is disposed in the sliding groove and is able to move along the sliding groove.

[0008] Furthermore, the sidewall of the chute is set as an inclined surface, and the roller is provided with a corresponding inclined conical surface on the side close to the inclined surface.

[0009] Furthermore, the angle between the inclined plane and the horizontal plane is equal to the angle between the inclined cone and the horizontal plane, and both angles are 60°-75°.

[0032] The inventive concepts of this disclosure will be described below using terminology commonly used by those skilled in the art to convey the essence of their work to others skilled in the art. However, these inventive concepts may be embodied in many different forms and should not be construed as limited to the embodiments described herein.

[0033] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments of the present invention can be combined with each other. The directional terms used in this application refer to the conventional orientation of cooking appliances in their normal assembly and placement states; please refer to the appendix for further details. Figure 1 The coordinates in the diagram.

[0034] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0035] To address the problem that the complex structures related to movement on existing drawers make assembly within the cooking cavity difficult, this embodiment proposes a drawer-type cooking appliance, as shown in the attached diagram. Figure 1-8 As shown, the drawer-type cooking appliance includes a cavity 2 and a drawer 4. The cavity 2 has a cooking chamber inside, and the drawer 4 is connected to the cavity 2 in a manner that allows it to move back and forth within the cooking chamber. The bottom wall 21 of the cavity 2 is provided with a slide groove 211 extending in the front-back direction. The bottom of the drawer 4 is provided with a roller 46, the rotation center axis of which is arranged in the left-right direction. The roller 46 is disposed in the slide groove 211 and can move along the slide groove 211.

[0036] Therefore, based on existing drawer-type cooking appliances, this application provides a sliding groove 211 on the bottom wall 21 of the cavity 2, so that the drawer 4 can only move along the sliding groove 211 via the roller 46. On the one hand, this ensures the smoothness of the drawer during the pulling process, and on the other hand, the sliding groove 211 can limit the roller 46 in the left and right directions. Compared with the prior art, it eliminates the need for rollers with a vertical rolling axis, and also achieves the limitation of the drawer in the left and right directions, preventing the drawer from wobbling left and right during the pulling process.

[0037] Correspondingly, while also solving the problem of drawer wobbling, this application, compared with the prior art, can effectively reduce the number of rollers and reduce the structural complexity of moving parts on the drawer, which helps to reduce the difficulty of assembling the drawer in the cooking cavity.

[0038] The sidewall of the slide groove 211 is set as an inclined surface 2111, and the roller 46 is provided with a corresponding inclined cone surface 461 on the side near the inclined surface 2111. This ensures that the roller 46 moves within the slide groove 211 while also improving the ability of the slide groove 211 to limit the roller 46 to the left and right, effectively preventing the roller 46 from deviating in the left and right direction and preventing the drawer from wobbling left and right during the pulling process. Preferably, the angle between the inclined surface 2111 and the horizontal plane is equal to the angle between the inclined cone surface 461 and the horizontal plane, and both are 60°-75°, preferably 70°. Correspondingly, the inclined surface 2111 and the inclined cone surface 461 are provided correspondingly, and they are undoubtedly parallel. It should be noted that the angle between two surfaces in this application refers to the acute angle formed between the two surfaces.

[0039] The drawer 4 includes a door 44, a support frame 45, and a slide rail assembly. One side of the support frame 45 is connected to the door 44, and a roller 46 is provided at the bottom of the other side. The drawer 4 is slidably connected to the cavity 2 via the slide rail assembly. Therefore, based on the slidable connection between the drawer 4 and the cavity 2 via the slide rail assembly, in addition to the structure shown in the attached drawings, this application can even solve the problem of drawer wobbling by providing only one roller 46 and a corresponding slide groove 211, further reducing the structural complexity of the moving parts on the drawer.

[0040] The support frame 45 has a mounting flange 452 at its front, which is connected to the door 44. The support frame 45 has a mounting plate 451 at its rear, which extends downwards to form a mounting section 4511 located below the support frame 45. The roller 46 is connected to the mounting section 4511. Both the mounting flange 452 and the mounting plate 451 can be integrally stamped during the processing of the support frame 45, eliminating the need for additional setup or assembly, thus simplifying the overall structure of the support frame 45 and the drawer 4.

[0041] Regarding the assembly between drawer 4, slide rail assembly, and cavity 2, the slide rail assembly includes a fixed rail and a movable rail, both of which are arranged in the front-to-back direction. The fixed rail is connected to the cavity 2, and the movable rail is connected to the door 44 and / or the support frame 45. The movable rail can slide along the fixed rail.

[0042] The fixed rail has a groove structure, and the movable rail can slide within the groove. The rail assembly includes a connecting rail, which is disposed between the fixed rail and the movable rail. The width of the connecting rail does not exceed the width of the groove of the fixed rail, so that the connecting rail is located within the groove. The movable rail is wrapped around the connecting rail and is driven to slide by the connecting rail.

[0043] To further improve the connection stability of the fixed rail, the drawer-type cooking appliance includes a front panel 3, which is connected to the front side of the cavity 2. While the main body of the fixed rail is connected to the cavity 2, one end of the fixed rail is connected to the front panel 3, and the other end is connected to the rear panel of the cavity 2. This allows the entire fixed rail to be more securely fixed inside the cooking appliance, providing a stable support for the movable rail and preventing unnecessary displacement or loosening of the movable rail during sliding.

[0044] To improve the smoothness of the drawer's operation during pulling out, this application provides three slide rail assemblies, designated as the first slide rail assembly 41, the second slide rail assembly 42, and the third slide rail assembly 43. Specifically, the drawer-type cooking appliance includes a front panel 3 and a housing 1. The front panel 3 is connected to the front side of the housing 1 and the cavity 2. The first slide rail assembly 41 is located on the left side of the drawer 4, the second slide rail assembly 42 is located on the right side of the drawer 4, and the third slide rail assembly 43 is located at the bottom of the drawer 4. Any one of the slide rail assemblies can extend or retract relative to the front panel 3. Thus, by using the three connecting surfaces and three slide rails of the drawer, the direction of the drawer's pulling out is limited, ensuring smooth operation and preventing unnecessary jamming during the process.

[0045] A first space 101, a second space 102, and a third space 103 are provided between the outer shell 1 and the cavity 2. The first space 101 and the second space 102 are located on the left and right sides of the cavity 2, respectively, and the third space 103 is located at the bottom of the cavity 2. Specifically, the first space 101 is formed between the left side wall of the cavity 2 and the left side plate 11 of the outer shell 1, the second space 102 is formed between the right side wall of the cavity 2 and the right side plate 12 of the outer shell 1, and the third space 103 is formed between the bottom wall 21 of the cavity 2 and the bottom plate 13 of the outer shell 1.

[0046] The first slide rail assembly 41 is disposed inside the first space 101, the second slide rail assembly 42 is disposed inside the second space 102, the third slide rail assembly 43 is disposed inside the third space 103, and the front plate 3 covers the front side of the first space 101, the second space 102 and the third space 103.

The first fixed rail is connected to the cavity 2, the first movable rail 412 is slidably connected to the first fixed rail, and the first connecting rail 413 is fixedly connected to the first movable rail 412, preferably by fasteners. Correspondingly, the first opening 31 is provided with a clearance notch to allow space for the fasteners of the first connecting rail 413 and the first movable rail 412.

[0049] The second slide rail assembly 42 includes a second fixed rail 421, a second movable rail 422, and a second connecting rail 423. The second fixed rail 421 is connected to the cavity 2, the second movable rail 422 is slidably connected to the second fixed rail 421, and the second connecting rail 423 is fixedly connected to the second movable rail 422, preferably by fasteners. Correspondingly, the second opening 32 is provided with a clearance notch to allow space for the fasteners of the second connecting rail 423 and the second movable rail 422.
