The term "and / or" used in the specification of the present application includes any and all combinations of one or more related listed items.

[0027] Please refer to Figures 1 to 5 , the present application provides a microwave oven, comprising: a microwave oven body 10, a furnace door 20, a guide assembly 30 and a bearing assembly 40, the microwave oven body 10 has an inner cavity, the front side of the inner cavity has an opening, the microwave oven body 10 is provided with a longitudinal guide rail 11 extending along the front and back direction. The bearing assembly 40 is arranged on the guide assembly 30, the guide assembly 30 includes a guide frame 31 which is in sliding fit with the longitudinal guide rail 11 and a transverse guide rail 32 which extends along the left and right direction of the microwave oven body 10. The furnace door 20 is rotatably installed on the opening side of the microwave oven body 10, and the furnace door 20 is provided with a guide rod 21 which is in sliding fit with the transverse guide rail 32, so as to take the guide assembly 30 out of or into the inner cavity of the microwave oven body 10 when the furnace door 20 rotates relative to the microwave oven body 10. In this way, by arranging the sliding fit guide rod 21 and the transverse guide rail 32, and the sliding fit guide frame 31 and the longitudinal guide rail 11, when the furnace door 20 is opened, the guide rod 21 slides in the transverse guide rail 32 and pulls the guide assembly 30 out of the inner cavity of the microwave oven body 10. Since the bearing assembly 40 is arranged on the guide assembly 30, the bearing assembly 40 is used to bear food, therefore, the bearing assembly 40 can be pulled out by opening the furnace door 20, so that the food placed on the bearing assembly 40 can be conveniently taken. At the same time, when the furnace door 20 is closed, the bearing assembly 40 can be pushed into the inner cavity of the microwave oven body 10 together with the guide assembly 30, so that it is very convenient to use. The microwave oven structure is very simple and compact, and is suitable for household use.

[0028] Further, please refer to Figure 2 , Figure 4 and Figure 5 , wherein Figure 2The bearing assembly 40 includes a mounting platform 41, a driving motor 42 and a bearing disc 43. The mounting platform 41 is fixedly connected to the guide frame 31. The driving motor 42 is mounted on the mounting platform 41. An output shaft 421 of the driving motor 42 extends upward. The bearing disc 43 is connected to an upper end of the output shaft 421. Since the mounting platform 41 is fixedly connected to the guide frame 31 and the driving motor 42 is mounted on the mounting platform 41, the rotation control of the bearing disc 43 by the driving motor 42 and the movement of the guide assembly 30 are not interfered with each other. When heating food, the food placed on the bearing disc 43 can rotate relative to the guide assembly 30, so that the food is heated more uniformly. In the embodiment, the output shaft 421 of the driving motor 42 is directly connected to the bearing disc 43. The power output path is short, and the structure is very simple. The bearing disc 43 can be fixedly connected to the output shaft 421 of the driving motor 42 by clamping, threaded connection, bonding or the like. The application is not limited in this regard.

[0029] Further, the inner cavity of the microwave oven body 10 is provided with an inner liner bottom plate 12. The inner liner bottom plate 12 divides the inner cavity into a cooking cavity 13 located on the upper side of the inner liner bottom plate 12 and a mounting cavity 14 located on the lower side of the inner liner bottom plate 12. The longitudinal guide rail 11 is arranged in the mounting cavity 14. The inner liner bottom plate 12 is provided with an avoiding groove 121 extending in the front-rear direction. The output shaft 421 of the driving motor 42 penetrates the avoiding groove 121. The bearing disc 43 is arranged in the cooking cavity 13. The driving motor 42, the mounting platform 41 and the guide frame 31 are arranged in the mounting cavity 14. In this way, the inner cavity space of the microwave oven body 10 can be reasonably divided by arranging the inner liner bottom plate 12. Only the bearing disc 43 is reserved in the cooking cavity 13, so that the oil stains adhered to the guide assembly 30 can be avoided to cause difficult cleaning. Moreover, the longitudinal guide rail 11, the guide frame 31, the mounting platform 41 and the driving motor 42 are arranged in the mounting cavity 14. The structure is very compact.

[0030] Further, the guide assembly 30 further includes a front baffle 33 arranged at the front end of the guide frame 31. The transverse guide rail 32 is arranged on the front side of the front baffle 33. In this way, the connection strength of the transverse guide rail 32 and the guide frame 31 is increased. The structure of the guide assembly 30 is more stable. Moreover, the front baffle 33 can block the mounting cavity 14 from the front side to reduce heat leakage.

[0031] Further, the guide assembly 30 further includes an upper baffle 34. One end of the upper baffle 34 is connected to the upper end of the front baffle 33. The other end of the upper baffle 34 extends to the outer wall of the output shaft 421 of the driving motor 42. When the oven door 20 is closed, the upper baffle 34 blocks the avoiding groove 121 from the upper side. In this way, the oil stains can be avoided to enter the mounting cavity 14 from the avoiding groove 121 when heating food, so that the cleanliness of the mounting cavity 14 can be maintained. In the embodiment, when the oven door 20 is closed, the upper baffle 34 is tightly attached to the upper surface of the inner liner bottom plate 12. It is ensured that the oil stains cannot enter the avoiding groove 121 from the gap between the upper baffle 34 and the inner liner bottom plate 12.

[0032] In this embodiment, one end of the upper baffle 34 is provided with a semi-circular notch, and the output shaft 421 of the drive motor 42 is partially housed in the semi-circular notch. The upper baffle 34 provides a certain support for the output shaft 421 of the drive motor 42, which helps to ensure the stability of the rotation of the output shaft 421.

[0033] Furthermore, the microwave oven body 10 is also provided with a front panel 15, which is located at the front opening of the mounting cavity 14. When the oven door 20 is closed, the front baffle 33 and the front panel 15 cooperate to block the front opening of the mounting cavity 14. In this way, heat and microwave leakage inside the cooking cavity 13 can be avoided.

[0034] In this embodiment, the front baffle 33 has stepped sides, and the shape of the front panel 15 is adapted to the shape of the front baffle 33, also being stepped, to ensure that when the furnace door 20 is closed, the side wall of the front baffle 33 and the side wall of the front panel 15 are tightly fitted, thereby forming a good seal.

[0035] like Figure 2 As shown, in this embodiment, there are two longitudinal guide rails 11 and two guide frames 31, with each guide frame 31 corresponding to one of the longitudinal guide rails 11. The mounting platform 41 is positioned between the two guide frames 31. This makes the structure more stable, preventing food placed on the support assembly 40 from falling out when the oven door 20 is opened or closed. Of course, in other embodiments, the longitudinal guide rails 11 and guide frames 31 can be one, three, or more; this application does not impose any limitations on this.

[0036] Furthermore, the longitudinal guide rail 11 is configured as a protruding rail protruding from the inner wall of the cavity, and the guide frame 31 is provided with a longitudinal groove 311, into which the protruding rail is inserted. Thus, the longitudinal guide rail 11 and the guide frame 31 have a very simple structure and are easy to manufacture. In this embodiment, the guide frame 31 includes two parallel rods, with a groove formed between the two rods, resulting in a very simple structure.

[0037] Furthermore, the transverse guide rail 32 is provided with a transverse sliding groove 321, and the guide rod 21 is located at the lower end of the oven door 20 and inserted into the transverse sliding groove 321. This ensures that the guide rod 21 is always in sliding engagement with the transverse guide rail 32, thereby easily pulling the guide assembly 30 out or moving it into the inner cavity of the microwave oven body 10 through the guidance of the guide rod 21. The transverse guide rail 32 in this embodiment has a very simple structure and is easy to manufacture.

[0038] Furthermore, the transverse groove 321 extends through the upper and lower end faces of the transverse guide rail 32, and the guide rod 21 extends from the lower end of the transverse groove 321. In this way, the guide rod 21 is less likely to get stuck in the transverse groove 321, thus making it easier to open or close the furnace door 20.

[0039] Any combination of the technical features in the above-described embodiments can be made, and for the sake of brevity, not all possible combinations are described, however, it is to be understood that the application embraces all such possible combinations.

[0040] The above-described embodiments only express several implementation manners of the application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the patent application scope. It should be pointed out that for ordinary skilled persons in the art, several modifications and improvements can be made without departing from the concept of the application, and these all belong to the protection scope of the application. Therefore, the patent protection scope of the application should be subject to the appended claims.
