Technical Field

[0001] This utility model relates to the field of kitchen appliance technology, and more specifically, to a drawer-type microwave oven. 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. Because the door assembly of most cooking appliances in current technology is located on the front and hinged to the cooking cavity, removing food requires first sliding it a short distance before reaching upwards, making food removal inconvenient. Drawer-type cooking appliances allow food to be easily removed from the cooking cavity, making it easier for users to retrieve cooked food. Due to their convenience, drawer-type cooking appliances are gradually gaining market share.

[0003] In existing drawer-type cooking appliances, slide rails are typically installed only on the left and right sides of the drawer, which is connected to the cooking cavity via these rails. However, due to the considerable weight of the drawer, especially when there is a lot of food, the drawer's weight increases dramatically, causing the entire drawer to sag. When pulling the drawer out, the bottom of the sagged drawer is prone to jamming. Utility Model Content

[0004] In view of this, the present invention aims to propose a drawer-type microwave oven to solve the problem of jamming during the pull-out operation in the prior art.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0040] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. In addition, the orientations involved in the following specific embodiments are briefly explained: the directions or positional relationships indicated by "front," "rear," "up," "down," "left," "right," "top," and "bottom" mentioned in the embodiments refer to the orientations or positional relationships shown in the accompanying drawings. The term "on..." means directly or indirectly supported by the... element.

[0041] It should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, an electrical connection, or a connection that allows for communication; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0042] like Figures 1-10 As shown, a drawer-type microwave oven includes a shell 1, a cavity 2, a front panel 3, and a drawer 4. The cavity 2 is disposed inside the shell 1 and is used to hold food to be heated. The front panel 3 connects the front of the shell 1 and the cavity 2. The drawer 4 is connected to the front of the cavity 2 and is used to seal or open the opening of the cavity 2. A first slide rail 41 and a second slide rail 42 are respectively connected to the left and right sides of the drawer 4. Both the first slide rail 41 and the second slide rail 42 pass through the front panel 3 and connect to the cavity 2. Both the first slide rail 41 and the second slide rail 42 can extend or retract relative to the front panel 3. The lower part of drawer 4 is also connected to a third slide rail 43. The third slide rail 43 is connected to the lower part of drawer 4 near the left or right side, that is, the third slide rail 43 is offset from the middle position of drawer 4. The third slide rail 43 also passes through the front panel 3 and connects to the cavity 2. Thus, the drawer's pulling direction is limited by the setting of three connecting surfaces and three slide rails to ensure the smooth operation of the drawer. At the same time, the offset setting of the third slide rail avoids interference between the third slide rail and the waveguide box, ensuring that the third slide rail can work normally and preventing the lower part of the drawer from getting stuck during the process of pulling the drawer out.

[0043] Specifically, 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. The left and right sides of the drawer 4 are connected to the cavity 2 by a first slide rail 41 and a second slide rail 42, respectively. The first slide rail 41 is located inside the first space 101, the second slide rail 42 is located inside the second space 102, and the third slide rail 43 is located inside the third space 103. A waveguide box is also provided inside the third space 103. In the left-right direction, the waveguide box is located in the middle of the third space 103. The corresponding third slide rail 43 is located on the left or right side of the third space 103 to avoid interfering with the normal operation of the waveguide box and also to prevent interference between the third slide rail and the waveguide box when the drawer sinks.

[0044] The cavity 2 includes side walls 21, a top wall 22, a bottom wall 23, and a rear wall 25. The two side walls 21 are arranged parallel to each other, with the top of the side walls 21 connected to the top wall 22 and the bottom of the side walls 21 connected to the bottom wall 23. Furthermore, a connecting wall 24 is provided between the side walls 21 and the top wall 22. The connecting wall 24 is inclined to ensure a smooth transition between the side walls 21 and the top wall 22, avoiding dead corners for hygiene.

[0045] Furthermore, heat dissipation holes are provided on the connecting wall 24 for heat dissipation inside the cavity 2.

[0046] The corresponding outer shell 1 includes a side plate 11, a rear plate 12, and a bottom plate 13. The left side plate 11 forms a first space 101 with the left side wall 21 of the cavity 2; the right side plate 11 forms a second space 102 with the right side wall 21 of the cavity 2; and the bottom plate 13 forms a third space 103 with the bottom wall 23 of the cavity 2. The front plate 3 covers the front of the first space 101, the second space 102, and the third space 103. A second opening 33 is provided on the front plate 3 on both sides. First slide rails 41 and second slide rails 42 on both sides pass through the second opening 33 and are respectively disposed inside the first space 101 and the second space 102. A third opening 34 is also provided near the lower part of the front plate 3, and the third slide rail 43 passes through the third opening 34 and connects to the interior of the third space 103.

[0047] The first slide rail 41 and the second slide rail 42 are symmetrically arranged. Taking the second slide rail 42 as an example, the second slide rail 42 includes a second fixed rail 421 and a second movable rail 422. The second fixed rail 421 is fixedly arranged relative to the cavity 2, and the second movable rail 422 can slide along the second fixed rail 421. Both the second fixed rail 421 and the second movable rail 422 extend in the direction from the front panel 3 to the rear panel 12, thereby restricting the sliding direction of the drawer.

[0048] The second fixed rail 421 is fixedly installed on the outer side wall 21 of the cavity 2. The front end of the second fixed rail 421 is fixedly connected to the front plate 3, and the rear end of the second fixed rail 421 is connected to the rear wall 25 of the cavity 2. The side of the second fixed rail 421 is in contact with the outer side wall 21, and the second fixed rail 421 is fixedly connected to the side wall 21. The second fixed rail 421 will not move relative to the side wall 21, thus ensuring the smooth operation of the slide rail. Specifically, the connection between the second fixed rail 421 and the side wall 21 can be welding, riveting, or screw connection, or the second fixed rail 421 and the side wall 21 can be integrally set to ensure the stability between them.

[0049] In this embodiment, the front end of the second fixed rail 421 is riveted and fixed to the front plate 3, and the rear end of the second fixed rail 421 is riveted and fixed to the rear wall 25 of the cavity 2. Specifically, a first riveting hole 35 is provided on the front plate 3, and a first riveting member 4211 fixes the front end of the second fixed rail 421 to the front plate 3. A second riveting hole is provided on the rear wall 25 of the cavity 2, and a second riveting member 4212 fixes the rear end of the second fixed rail 421 to the rear wall 25.

[0050] The second fixed rail 421 is configured as a groove structure, and the second movable rail 422 can slide within the groove. The second slide rail 42 also includes a second connecting rail 423, which is positioned between the second movable rail 422 and the second fixed rail 421. The width of the second connecting rail 423 in the vertical direction does not exceed the width of the groove in the vertical direction. The second connecting rail 423 is located within the groove, and the second movable rail 422 wraps around the second connecting rail 423, causing the second movable rail 422 to slide. Furthermore, the width of the second movable rail 422 in the vertical direction is greater than the width of the groove in the vertical direction, so that the second movable rail 422 provides a sliding wrapping effect on the second fixed rail 421, preventing debris from being brought into the groove during sliding.

[0051] To further ensure the smooth sliding of the second movable rail 422 along the second connecting rail 423, the second movable rail 422 and the second connecting rail 423 are fixedly connected. Specifically, screw holes are provided on the second movable rail 422, and second screws 424 or rivets are used to integrally connect the second movable rail 422 and the second connecting rail 423, allowing the second movable rail 422 and the second connecting rail 423 to extend outward or retract inward through the second opening 33. Furthermore, the screw holes on the second movable rail 422 are located at the centerline in the vertical direction of the second movable rail 422, and multiple screw holes 422 are evenly distributed along the length of the second movable rail 422, ensuring a firm connection between the second movable rail 422 and the second connecting rail and preventing the second movable rail 422 from shaking during sliding.

[0052] A first clearance notch 331 is also provided on the second opening 33 of the front plate 3. The first clearance notch 331 is recessed on the outer side of the front plate 3. When the second movable rail 422 slides through the second opening 33, the first clearance notch 331 is used to avoid the second screw 424, so as to prevent jamming during sliding.

[0053] It should be noted that in this embodiment, the structure and connection method of the first slide rail 41 and the second slide rail 42 are the same, the only difference is that they are set in different positions and are located on both sides of the cavity 2 respectively.

[0054] The third slide rail 43 includes a third fixed rail 431 and a third movable rail 432. The third fixed rail 431 is fixedly disposed relative to the cavity 2, and the third movable rail 432 can slide along the third fixed rail 431. Both the third fixed rail 431 and the third movable rail 432 extend in the direction from the front panel 3 to the rear panel 12, thereby restricting the sliding direction of the drawer.

[0055] The third fixed rail 431 is fixedly installed on the lower side of the bottom wall 23 of the cavity 2. The front end of the third fixed rail 431 is fixedly connected to the front plate 3, and the rear end of the third fixed rail 431 is connected to the rear wall 25 of the cavity 2. The upper surface of the third fixed rail 431 is in contact with the lower side of the bottom wall 23, and the third fixed rail 431 is fixedly connected to the bottom wall 23. The third fixed rail 431 will not move relative to the bottom wall 23, thus ensuring the smooth operation of the slide rail. Specifically, the connection between the third fixed rail 431 and the bottom wall 23 can be welding, riveting, or screw connection, or the third fixed rail 431 and the bottom wall 23 can be integrally set to ensure the stability between them.

[0056] The front end of the third fixed rail 431 is riveted and fixed to the front plate 3, and the rear end of the third fixed rail 431 is riveted and fixed to the rear wall 5 of the cavity 2 near the lower part. Correspondingly, a third front riveting hole 37 is provided at the lower part of the front plate 3, and a third rear riveting hole is provided at the lower part of the rear wall 25 of the cavity 2. The front and rear ends of the third fixed rail 431 are riveted and fixed respectively using riveting components.

[0057] The third fixed rail 431 is configured as a groove structure, and the third movable rail 432 can slide within the groove. The third slide rail 43 also includes a third connecting rail 433, which is positioned between the third movable rail 432 and the third fixed rail 431. The width of the third connecting rail 433 in the vertical direction does not exceed the width of the groove in the vertical direction. The third connecting rail 433 is located within the groove, and the third movable rail 432 is wrapped around the third connecting rail 433, causing the third movable rail 432 to slide. Furthermore, the width of the third movable rail 432 in the vertical direction is greater than the width of the groove in the vertical direction, so that the third movable rail 432 forms a sliding wrapping effect on the third fixed rail 431, preventing debris from being brought into the groove during sliding.

[0058] Screw holes are provided on the third movable rail 432, and the third movable rail 432 and the third connecting rail 433 are integrally connected by a third screw 434 or a rivet, so that the third movable rail 432 and the third connecting rail 433 can extend outward or retract inward through the third opening 34. Furthermore, the screw holes on the third movable rail 432 are located at the center line of the vertical direction of the third movable rail 432, and multiple screw holes are evenly distributed along the length of the third movable rail 432, so that the third movable rail 432 and the third connecting rail are firmly connected, preventing the third movable rail 432 from shaking during sliding.

[0059] Correspondingly, a second clearance notch 341 is provided on the third opening 34 of the front plate 3. The second clearance notch 341 is recessed into the lower part of the front plate 3. When the third movable rail 432 slides through the third opening 34, the second clearance notch 341 is used to avoid the third screw 434.

[0060] As part of the embodiment of this utility model, the front panel 3 is also provided with a first opening 32. There are two first openings 32, which are located near the left and right sides of the front panel 3 respectively. The first opening 32 is located above the second opening 33. When the drawer 4 is in the closed state, the door hook of the door body 44 passes through the first opening 32 and locks with the cavity 2.

[0061] A front air outlet 31 is also provided near the lower part of the front panel 3. The front air outlet 31 is connected to the third space 103 and is used to dissipate heat from the third space 103. Specifically, the lower part of the front panel 3 is connected to the bottom plate 13. The space enclosed by the bottom plate 13, the bottom wall 23 of the cavity 2, and the front panel 3 is the third space 103. A bottom air inlet 131 is provided near the rear side of the bottom plate 13. The cold air entering the third space 103 through the bottom air inlet 131 dissipates heat from the interior of the third space 103 and is then discharged to the outside through the front air outlet 31.

[0062] Furthermore, a lower folded edge 36 is provided at the lower part of the front plate 3. The lower folded edge 36 bends and extends backward, and a connecting hole 361 is provided on the lower folded edge 36. The front plate 3 is connected to the bottom plate 13 through the connecting hole 361 of the lower folded edge 36.

[0063] As one embodiment of this utility model, a heat baffle plate 14 is further provided at the lower part of the front plate 3, and the heat baffle plate 14 is connected and fixed to the lower part of the front plate 3 and / or the bottom plate 13. Preferably, the heat baffle plate 14 is also provided with screw holes corresponding to the connection holes 361 on the front plate 3, so that the front plate 3, the heat baffle plate 14 and the bottom plate 13 can be connected together by a single screw passing through them, reducing the use of screws.

[0064] The heat baffle 14 is designed to extend forward and is located below the front air outlet 31, causing it to protrude forward relative to the front panel 3. This serves to block and reflect the hot air discharged from the front air outlet 31, guiding it upward and preventing it from flowing back through the bottom plate 13 to the bottom air inlet 131 and entering the third space 103. Furthermore, the protruding heat baffle 14 structure prevents foreign objects below the door assembly from interfering with it.

[0065] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
