[0047] Steam generated by the steam generator assembly 12 enters the tableware storage cabinet 2 for disinfection through the first steam inlet 111 and the second steam inlet 211. Steam exits the oven body through the second steam outlet 212 and the first steam outlet 112. In this embodiment of the invention, the combined tableware disinfection device keeps the tableware hidden inside the storage cabinet 2 during disinfection, eliminating the need to remove the tableware and preventing oil contamination from the oven shell, thus avoiding secondary contamination during the disinfection process. After disinfection, only the tableware storage cabinet 2 needs to be removed from the oven shell 11, without removing the tableware, preventing dust contamination of the tableware.

[0048] like Figure 3-4As shown, in a preferred embodiment of the present invention, a first rubber ring 3 and a second rubber ring 4 are further included, with one end of the first rubber ring 3 and the second rubber ring 4 respectively sealed and fitted into the second steam inlet hole 211 and the second steam outlet hole 212.

[0049] When the tableware storage cabinet 2 is installed inside the housing, the other ends of the first rubber ring 3 and the second rubber ring 4 are respectively sealed and connected to the first steam inlet 111 and the first steam outlet 112. For example, the specific connection method can be that the other ends of the first rubber ring 3 and the second rubber ring 4 are both sealed and abutted against the rear side wall of the housing 11 and respectively surround the first steam inlet 111 and the first steam outlet 112, so as to achieve the sealing of the steam channel, avoid secondary contamination, and avoid air leakage that would reduce the disinfection effect.

[0050] Of course, when the tableware storage cabinet 2 is installed inside the housing, the other ends of the first rubber ring 3 and the second rubber ring 4 are not limited to sealingly abutting against the rear side wall of the housing 11. For example, when the tableware storage cabinet 2 is installed inside the housing, the other ends of the first rubber ring 3 and the second rubber ring 4 can be detachably and sealingly fitted into the first steam inlet 111 and the first steam outlet 112, respectively. Those skilled in the art can select the sealing connection method of the first rubber ring 3 and the second rubber ring 4 according to actual needs.

[0051] like Figure 6-8 As shown, in a preferred embodiment of the present invention, the steam oven body 1 further includes a fan 14 and a fan mounting plate 15.

[0052] The fan mounting plate 15 and the rear side wall of the housing 11 together form a hot air circulation channel 16, and the fan blades of the fan 14 are installed in the hot air circulation channel 16.

[0053] The rear side wall of the housing 11 is provided with a first air inlet 113 and a first air outlet 114 corresponding to the hot air circulation channel 16. The tableware storage cabinet 2 is provided with a second air inlet 213 corresponding to the first air inlet 113 and a second air outlet 214 corresponding to the first air outlet 114. When the tableware storage cabinet 2 is installed in the housing, the second air inlet 213 is connected to the first air inlet 113 and the second air outlet 214 is connected to the first air outlet 114.

[0054] When the fan blades of the blower 14 rotate, the air inside the tableware storage cabinet 2 is drawn into the hot air circulation channel 16 through the first air outlet 114 and the second air outlet 214, and then blown into the tableware storage cabinet 2 through the first air inlet 113 and the second air inlet 213, repeating the cycle to form a circulation channel and improve the uniformity of steam and hot air.

[0055] like Figure 3-4 As shown, in a preferred embodiment of the present invention, a third rubber ring 5 and a fourth rubber ring 6 are also included.

[0056] One end of the third rubber ring 5 is sealed and fitted into the second air inlet 213, and one end of the fourth rubber ring 6 is sealed and fitted into the second air outlet 214.

[0057] When the tableware storage cabinet 2 is installed inside the housing, the other ends of the third rubber ring 5 and the fourth rubber ring 6 are sealed against the rear side wall of the housing 11 and surround the first air inlet 113 and the first air outlet 114 respectively, so as to achieve the sealing of the airflow circulation channel and avoid secondary pollution.

[0058] Of course, when the tableware storage cabinet 2 is installed inside the housing, the other ends of the third rubber ring 5 and the fourth rubber ring 6 are not limited to sealingly abutting against the rear side wall of the housing 11. For example, when the tableware storage cabinet 2 is installed inside the housing, the other ends of the third rubber ring 5 and the fourth rubber ring 6 can be detachably and sealingly fitted into the first air inlet 113 and the first air outlet 114, respectively. Those skilled in the art can select the sealing connection method of the third rubber ring 5 and the fourth rubber ring 6 according to actual needs.

[0059] like Figure 3 , 5 As shown in Figures 6 and 7, in a preferred embodiment of the present invention, the steam oven body 1 further includes a first temperature sensor 17 and a humidity sensor 18 mounted on the housing 11, and the first temperature sensor 17 and the humidity sensor 18 are electrically connected to the controller.

[0060] The probes of the first temperature sensor 17 and the humidity sensor 18 both extend into the housing 11. The tableware storage cabinet 2 has a first through hole 215 and a second through hole 216 respectively corresponding to the first temperature sensor 17 and the humidity sensor 18.

[0061] When the tableware storage cabinet 2 is installed inside the housing, the first temperature sensor 17 and the humidity sensor 18 extend into the tableware storage cabinet 2 through the first through hole 215 and the second through hole 216 respectively, so as to collect the temperature and humidity inside the tableware storage cabinet 2 during the disinfection process.

[0062] like Figure 3-4 As shown, in a preferred embodiment of the present invention, a fifth rubber ring 7 and a sixth rubber ring 8 are also included.

[0063] The fifth rubber ring 7 and the sixth rubber ring 8 are respectively sealed and fitted into the first through hole 215 and the second through hole 216. When the tableware storage cabinet 2 is installed in the shell, the fifth rubber ring 7 and the sixth rubber ring 8 are respectively sealed and fitted onto the probe of the first temperature sensor 17 and the probe of the humidity sensor 18 to achieve a seal and prevent air leakage.

[0064] like Figure 2-4 As shown, in a preferred embodiment of the present invention, the tableware storage cabinet 2 includes a cabinet body 21, a first cover 22, a second cover 23, and a tableware rack 24.

[0065] The cabinet body 21 and the first cover body 22 together form a cavity for accommodating tableware. The second steam inlet 211 and the second steam outlet 212 are both located on the rear side wall of the cabinet body 21.

[0066] The second cover 23 is installed on the rear side wall of the cabinet 21, and the second cover 23 seals the second steam inlet 211, the second steam outlet 212, the second air inlet 213, the second air outlet 214, the first through hole 215 and the second through hole 216 to avoid secondary pollution and prevent mosquitoes and dust from entering the tableware when it is placed, thereby improving the hygiene of the tableware.

[0067] The cutlery rack 24 is installed inside the cutlery storage cabinet 2. The cutlery rack 24 includes at least one mesh or grid-like placement platform and multiple support legs, such as... Figure 3-4 As shown, the cutlery rack 24 includes two layers of shelves. Of course, the number of shelves is not limited to two; those skilled in the art can choose the number of shelves according to actual needs.

[0068] like Figure 5 As shown, in a preferred embodiment of the present invention, the outer ring surfaces of the first rubber ring 3, the second rubber ring 4, the third rubber ring 5 and the fourth rubber ring 6 are all provided with annular grooves 31 and annular clearance grooves 32. The annular grooves 31 are engaged with the walls of the second steam inlet hole 211 and the second steam outlet hole 212. The annular clearance grooves 32 are configured to provide space for deformation and guide deformation during elastic deformation, thereby improving the sealing performance after contact with the rear side wall of the housing 11.

[0069] like Figure 5 As shown, in a preferred embodiment of the present invention, the side wall of the annular clearance groove 32 away from the annular slot 31 is inclined, and the diameters of the first rubber ring 3 and the second rubber ring 4 gradually decrease from the annular clearance groove 32 to the direction away from the annular slot 31, so that after abutting against the rear side wall of the housing 11, the end of the first rubber ring 3 away from the annular slot 31 folds inward and deforms.

[0070] like Figure 6-8 As shown, in a preferred embodiment of the present invention, the fan mounting plate 15 is provided with a third steam inlet hole, which is connected to the hot air circulation channel 16. The steam outlet end of the evaporator 124 is connected to the hot air circulation channel 16 through the third steam inlet hole, and the first steam inlet hole 111 connects the housing 11 and the hot air circulation channel 16.

[0071] For example, the position of the first steam inlet 111 corresponds to and is connected to the hot air circulation channel 16. The evaporator 124 of the steam generator assembly 12 is connected to the first steam inlet 111 through the hot air circulation channel 16. The first steam inlet 111 is located below the first air inlet 113. During sterilization, steam is delivered into the tableware storage cabinet 2 through the lower first steam inlet 111 and the upper first air inlet 113, improving the uniformity of steam in the tableware storage cabinet 2.

[0072] like Figure 7-8 As shown, in a preferred embodiment of the present invention, a heating element assembly installed in the hot air circulation channel 16 is also included. The heating element assembly is connected to the controller via a relay. The heating element assembly is ring-shaped and surrounds the fan blades of the fan 14 to achieve a hot air effect.

[0073] Preferably, the first steam inlet 111 is located between the lower and upper placement platforms of the tableware rack 21 to steam sterilize the tableware on the lower placement platform, while the first air inlet 113 is located above the upper placement platform of the tableware rack 21 to steam sterilize the tableware on the upper placement platform, so as to achieve uniform sterilization of the tableware and avoid uneven steam volume between the upper and lower placement platforms.

[0074] like Figure 6 As shown, in a preferred embodiment of the present invention, an L-shaped exhaust pipe 9 is also included, the lower end of which is connected to the first steam outlet 112 to discharge steam out of the oven body.

[0075] like Figure 3-4 As shown, in a preferred embodiment of the present invention, the lower part of the cabinet 21 is provided with first handle grooves 217 in the front, back, left and right directions, which are used to facilitate the user to manually lift the tableware storage cabinet 2 and pull the tableware storage cabinet 2 out of the shell 11.

[0076] like Figure 3-4 As shown, in a preferred embodiment of the present invention, the outer side wall of the cabinet 21 is provided with a plurality of limiting protrusions 218. When the tableware storage cabinet 2 is installed in the housing 11, the limiting protrusions 218 abut against the inner side wall of the housing 11 to position the tableware storage cabinet 2. This ensures that when the tableware storage cabinet 2 is pushed into the housing 11 for disinfection, the second steam inlet 211 is precisely aligned with the first steam inlet 111 and is sealed and connected, the second steam outlet 212 is precisely aligned with the first steam outlet 112 and is sealed and connected, the second air inlet 213 is precisely aligned with the first air inlet 113 and is sealed and connected, and the second air outlet 214 is precisely aligned with the first air outlet 114 and is sealed and connected, thus preventing air leakage.

[0077] like Figure 4As shown, in a preferred embodiment of the present invention, a first annular wall 219 is provided at the rear edge of the cabinet 21, and a second annular wall 231 is provided on one side of the second cover 23 to be sleeved and connected to the first annular wall 219 to fix the second cover 23.

[0078] Of course, the method of fixing the second cover 23 is not limited to the above-mentioned method. Those skilled in the art can choose the method of fixing the second cover 23 according to actual needs.

[0079] like Figure 4 As shown, in a preferred embodiment of the present invention, a second hand groove 221 is provided in the middle of the first cover 22, and a handle 222 is provided in the middle of the upper end of the second hand groove 221, so as to facilitate the user to grasp the first cover 22.

[0080] like Figure 2-4 As shown, in a preferred embodiment of the present invention, the inner sidewall of the housing 11 is provided with a protruding blocking portion 115. Optionally, the blocking portion 115 is located at the front of the top wall of the housing 11.

[0081] The outer wall of the first cover 22 is provided with an elastic protrusion 223 that matches the blocking part 115.

[0082] During the process of the tableware storage cabinet 2 being pushed into the housing 11, and as the elastic protrusion 223 passes through the blocking part, the elastic protrusion 223 rubs against the blocking part 115 and contracts downward, allowing the elastic protrusion 223 to pass through the blocking part 115. When the tableware storage cabinet 2 is pushed backward into the housing 11, the elastic protrusion 223 passes through the blocking part 115 and extends elastically. At this time, the elastic protrusion 223 is located behind the blocking part 115. At this time, the blocking part 115 limits the forward pulling direction of the elastic protrusion 223, preventing the tableware storage cabinet 2 from shifting forward during the disinfection process, which could lead to air leakage.

[0083] like Figure 3-4 As shown, in a preferred embodiment of the present invention, the cabinet 21 includes a first front side wall, a left side wall, a right side wall, a rear side wall and a bottom wall. The first front side wall, the left side wall, the right side wall, the rear side wall and the bottom wall together form a cavity for accommodating tableware. The height of the first front side wall is less than the height of the left side wall, the right side wall and the rear side wall, thereby increasing the opening of the cabinet 21 and making it easier for users to put or take out tableware from the cabinet 21.

[0084] The front end of the first cover 22 extends downward to form a second front sidewall 224. The lower end face of the second front sidewall 224 abuts against the upper end face of the first front sidewall. The first front sidewall of the cabinet 21 and the second front sidewall 224 of the first cover 22 together form the front sidewall of the tableware storage cabinet 2.

[0085] In a preferred embodiment of the invention, a second temperature sensor is further included, which is mounted on the evaporator 124 of the steam generator assembly 12 to detect the temperature of the evaporator 124.

[0086] In a preferred embodiment of the present invention, the steam oven body 1 further includes an outer shell and a door. The front of the outer shell has an opening, the shell 11 is installed inside the outer shell, and the door is movably installed at the front of the outer shell and used to open and close the opening. When disinfection is required, the door is opened and the tableware storage cabinet 2 is pushed back into the shell 11. The door is closed during the disinfection process.

[0087] Of course, the disinfection process is not limited to closing the door; the door can also be opened. Those skilled in the art can choose whether to close the door according to actual needs. However, the door must be closed when steaming or cooking food.

[0088] In a preferred embodiment of the present invention, the steam oven body 1 further includes an electric baking tube, which is installed at the top and / or bottom of the housing 11 for baking food.
