DETAILED DESCRIPTION
[0020] In order to make the technical means, creative features, purposes and effects of the utility model easy to understand, the utility model is further described below in combination with specific embodiments.
[0021] Please refer to Figures 1 to 3 The utility model provides a kind of technical scheme: microwave oven, including box 1 and baking tray 7, box 1 is provided with oven cavity 11, oven cavity 11 is provided with air outlet ceramic plate 12 and lower air outlet plate 13 respectively in upper portion and lower portion, baking tray 7 is placed in the upper portion of lower air outlet plate 13 when using, air outlet ceramic plate 12 and lower air outlet plate 13 are heated to the food on baking tray 7 when discharging hot air oppositely.
[0022] In the technical scheme, bracket 3 is slidably connected in oven cavity 11 and close to lower air outlet plate 13, preferably, two sides in oven cavity 11 are fixedly connected with guide rail 6 in specific implementation, and the two sides of bracket 3 are fixedly connected with bracket plate 31 that is forward and backward rolling cooperation with guide rail 6.The function of bracket 3 is to lift baking tray 7, when bracket 3 moves to the outside of oven cavity 11, baking tray 7 can be taken out to the outside of oven cavity 11, which is convenient to take and place articles on baking tray 7.
[0023] Further, two sides in oven cavity 11 are provided with transmission combination 5, door frame 4 is rotatably connected to the inner side of box door 2, the free end of door frame 4 is connected with transmission combination 5, when opening and closing box door 2, under the transmission of door frame 4 and transmission combination 5, bracket 3 moves forward and backward, that is to say, the movement of bracket 3 is linked and controlled by opening and closing action of box door 2, without the need for operator to directly operate bracket 3.
[0024] Specifically, transmission combination 5 includes positioning shaft 51, rotating sleeve 52 and guide sleeve 53, one end of positioning shaft 51 is fixedly connected with the side wall of oven cavity 11, positioning shaft 51 is close to the front side in oven cavity 11, rotating sleeve 52 is sleeved on positioning shaft 51, and one end of rotating sleeve 52 is fixedly connected with transmission gear 521 that is engaged with bracket plate 31, a row of teeth that is engaged with transmission gear 521 is arranged on the top of bracket plate 31 in specific implementation, when rotating sleeve 52 rotates, transmission gear 521 will drive bracket plate 31 to move.
[0025] Further, the other end of the rotating sleeve 52 is fixedly sleeved with a driving gear 522, the guide sleeve 53 is sleeved on the longitudinal rod 41 on the door frame 4 and is rotationally connected with the positioning shaft 51 on one side, the longitudinal rod 41 is engaged with the adjacent driving gear 522, specifically, one side of the longitudinal rod 41 is provided with a row of tooth grooves 411 engaged with the driving gear 522, one side of the guide sleeve 53 is fixedly connected with a limiting sleeve 531 sleeved outside the positioning shaft 51, and the limiting sleeve 531 is rotationally connected with the positioning shaft 51. Thus, when the longitudinal rod 41 slides relative to the guide sleeve 53, the driving gear 522 is driven to rotate, and the rotating sleeve 52 is driven to rotate, and the door frame 4 is driven to move when the box door 2 is opened and closed, wherein the pitch circle diameter of the driving gear 522 is greater than the pitch circle diameter of the transmission gear 521, and the arrangement can increase the stroke of the bracket 3.
[0026] In the embodiment, the inner side of the box door 2 is fixedly connected with a positioning plate 8, the front side of the positioning plate 8 is fixedly connected with a connecting sleeve 81 rotationally connected with the horizontal shaft 42 on the door frame 4, and the arrangement facilitates the disassembly of the horizontal shaft 42 and the box door 2. When liquid needs to be heated, in order to avoid the problem that the baking tray 7 moves and the liquid spills when the box door 2 is opened, the horizontal shaft 42 and the box door 2 are disassembled, and the opening and closing of the box door 2 is no longer linked to control the movement of the baking tray 7.
[0027] Further, the cross section of the connecting sleeve 81 is a C-shaped structure, the connecting sleeve 81 is snap-fitted with the horizontal shaft 42, and the snap-fitting manner makes the connection and disassembly of the horizontal shaft 42 and the box door 2 more labor-saving and convenient.
[0028] In the embodiment, one side of the guide rail 6 is provided with a track groove 61, and a row of rollers 611 abutting the upper and lower sides of the supporting plate 31 is arranged on the upper and lower sides in the track groove 61. When the supporting plate 31 moves, the rollers 611 are passively rolled, so that the moving resistance of the supporting plate 31 is greatly reduced, and the linkage control of the box door 2 is more labor-saving.
[0029] Working principle: when using, when the items to be heated need to be put into the baking cavity 11, the outer side handle of the box door 2 is manually held and pulled outwards, the box door 2 is opened by swinging downward, the door frame 4 moves outward, the longitudinal rod 41 drives the driving gear 522 to rotate, the transmission gear 521 drives the supporting plate 31 to move outward, and the bracket 3 carries the baking tray 7 to move outward. When the box door 2 is opened to the horizontal state, the baking tray 7 moves out to the outside of the baking cavity 11, and the operator can more conveniently place the items on the baking tray 7. After the placement is completed, the box door 2 is reset, the baking tray 7 enters the baking cavity 11, and then the oven is started.
[0030] Furthermore, it should be understood that although the specification is described in terms of embodiments, not every embodiment includes every feature described. The specification can include implicit combinations of explicitly mentioned features and / or explicit combinations of implicitely mentioned features. Each embodiment depends on the explicit combinations of features and / or the implicit combinations of features made specifically within that embodiment, and each such embodiment can be combined with every other such embodiment to create further embodiments.
