The front plate structure 113 is connected to the edge of the front opening of the cavity 111. The front plate structure 113 can have an adiabatic effect and is used to connect the edge of the front opening of the cavity 111 and the furnace door assembly 16, preventing the furnace door assembly 16 from directly covering the front opening of the cavity 111, preventing the edge of the front opening of the high - temperature heating cavity 111 from being directly exposed when the furnace door assembly 16 is opened, and thus preventing personnel from easily touching the edge of the front opening of the heating cavity 111 and causing scalding.

[0081] Further, please combine with 4,Figure 9 and Figure 10 As shown in the figure, the steam oven 1 further comprises a base assembly 17 and a housing 18, the base assembly 17 is connected with the cavity assembly 11, and the edge of the housing 18 is connected with the base assembly 17 and the cavity assembly 11.

[0082] Specifically, the base assembly 17 is connected with the cavity assembly 11 for bearing the cavity assembly 11; the edge of the housing 18 is connected with the base assembly 17, the front plate structure 113 and the back plate structure 112 for surrounding the cavity 111.

[0083] Specifically, the rear cover 15 is perpendicular to the base assembly 17, the back plate structure 112 is perpendicular to the base assembly 17, the front plate structure 113 is perpendicular to the base assembly 17, and the housing 18 is surrounded by the front plate structure 113, the back plate structure 112 and the base assembly 17 to form a surrounding state of the cavity 111. Not only does the base assembly 17 provide a bearing function for the cavity assembly 11, but also the cavity 111 can be surrounded by the base assembly 17 together with the housing 18 to form a protective function for the cavity 111. Therefore, not only the safety of the steam oven 1 is improved, but also the appearance of the steam oven 1 is improved.

[0084] For the convenience of understanding, the water flow path and the steam exhaust path of the steam oven 1 are described in the embodiment of the utility model, and it should be noted that, Figure 12 A in the figure represents the path of the steam generator 131 supplying steam to the heating cavity 1111, Figure 13 B in the figure represents the path of the excess steam in the heating cavity 1111 and the original oxygen in the cavity being discharged to the air outside the steam oven 1. Please refer to Figure 4 , Figure 12 and Figure 13As shown, the water tank 121 is arranged at the bottom of the base assembly 17 for storing water, and the water in the water tank 121 is pumped by the water pump 122 to the first water outlet 1211, and then flows to the first water supply pipe 123, and then enters the first water inlet 1221 of the water pump 122, and then is pumped by the water pump 122 to the second water outlet 1222, and then is transported to the second water inlet 1312 of the steam generator 131 through the second water supply pipe 124, and then is heated by the steam generator 131 to become steam; the steam is discharged from the steam outlet 1311 of the steam generator 131 to one of the three-way steam supply pipes 132, and then is discharged from the other two to the steam supply holes 1121 at the upper part of the heating cavity 1111, and then enters the inside of the heating cavity 1111 from the steam supply holes 1121; when the steam in the heating cavity 1111 is filled, the excess steam and the oxygen with a density greater than that of the steam in the inside are gradually expelled to the lower part of the heating cavity 1111 from the steam exhaust hole 1122; the steam discharged from the steam exhaust hole 1122 flows to the steam exhaust pipe 142, and then is discharged to the first communication member 1411 of the steam exhaust seat 141, and then is discharged from the first communication member 1411 to the second communication member 1412, and finally is discharged to the air outside the steam oven 1 through the second communication member 1412.

[0085] Any combination of the technical features in the above embodiments can be combined. In order to make the description simple, all possible combinations of the technical features in the above embodiments are not described, however, as long as the combination of the technical features does not exist, it should be considered as the scope of the present application.

[0086] The above embodiments only express several implementation manners of the present application, and the description is more specific and detailed, but it should not be understood as the limitation of the scope of the utility model patent. It should be pointed out that, for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application. Therefore, the protection scope of the present application patent should be subject to the appended claims.
