As shown, the door assembly 1 may include a touch screen assembly, a control system, and a door frame. The touch screen assembly may include a touch screen 101, a touch screen mount 104, a mount back cover 110, and a heat shield 111. A color screen 102 may be provided behind the touch screen 101 for displaying operation information, a menu, and the like to the user. The control system comprises an encoder 107 and a control panel arranged on the touch screen mount 104, wherein the encoder 107 comprises a knob 108 and a hardware knob 109 arranged thereon for insertion into the touch screen mount 104 via the transparency 106, and the control panel may be the android board 103. The knob 108 may also be coupled to the touch screen mount 104 by a threaded connection, a snap connection, glue, etc., as is known to those skilled in the art.

In addition, the control system may also include corresponding sensors, such as temperature sensors, radiation sensors, etc., to monitor, regulate and control various parameters during cooking, such as temperature and radiation levels, etc., during the cooking process.

The door frame includes an outer glass 112, a partition and an inner glass 116 sequentially disposed at the rear 104 of the touch screen, wherein the outer glass 112 and the inner glass 116 facilitate a user to observe food during cooking of the food, and the partition disposed between the outer glass 112 and the inner glass 116 may be a microwave partition 118 for shielding and isolating microwaves generated by the micro-steamer to reduce harm of the microwaves to people. In addition, the door frame further includes an outer glass fixing member 113 for fixing the outer glass 112, an outer glass fixing member cover 119 engaged with the outer glass fixing member 113, and an outer door sealant 117 installed in the outer glass fixing member cover 119. The outer door sealant 117 prevents steam from entering the door assembly during steaming in the micro-steamer, which can negatively affect the components of the door assembly, such as electrical leakage, corrosion of electronic components, etc.

The door assembly 1 further includes a camera 105 installed in the touch screen holder 104 for recognizing food, two-dimensional codes or bar codes placed under the camera 105 and providing feedback to the control system so that a suitable recipe is displayed on the touch screen 101. The user can select the displayed menu according to the preference and the requirement of the user.

In addition, a wire transfer block 120 for transferring a wire of the control system, and a micro switch may be provided in the door assembly 1, and the micro switch includes a micro switch pull tab rotating column 114 and a micro switch pull tab 115 to interact with the micro switch on the body assembly 2.

Fig. 7 is an exploded view of a body assembly and a water tank assembly of the micro-steamer according to an embodiment of the present invention. As shown in fig. 7, the body assembly 2 includes a body frame, a body 202 disposed in a wrapping manner on the body frame, and an oven 201 provided on a rear sidewall of the body frame for cooking food placed in an inner cavity of the micro-steamer. A glass tray 203 or a hardware tray 204 for containing food is slidably placed on guide rails provided on the inner side of the side walls of the body frame to facilitate the taking out and putting in of food, as clearly shown in fig. 2 and 7. As known to those skilled in the art, the material of the tray may include any material that facilitates heat conduction, such as copper, aluminum, titanium, etc., in addition to glass and hardware.

The water tank assembly mainly includes a cold water tank 3 and a hot water tank 4. The cold water tank 3 and the hot water tank 4 may be detachably inserted into seats of the body assembly 2 to facilitate cleaning and replacement of the tank assemblies. The cold water tank 3 pumps cold water from the cold water tank to the hot water tank 4 through an output pipe, a water pump, and the like. The hot water tank 4 includes a stainless steel tank body for containing water to be heated, and a heat generating film is installed in a sealed space constituted by the stainless steel tank body and a stainless steel tank body bottom cover for heating the water in the stainless steel tank body to generate steam. The sealed space can isolate the heat generating film from the generated steam during the heating process. The steam can be guided into the inner cavity of the micro-steaming and baking machine through the corresponding pipe fitting so as to steam the food placed in the inner cavity.

After assembling the respective components of the micro-steamer according to the present invention together, the door assembly 1 is first closed such that the micro switch pull tab rotating column 114 and the micro switch pull tab 115 provided on the door frame close the micro switch on the body assembly 2 to turn on the power. Next, the prepared food or two-dimensional code, barcode is placed under the touch screen holder 104, and the camera 105 installed in the touch screen holder 104 is used to recognize the food, two-dimensional code, or barcode placed under the camera 105 and provide feedback to the control system so that a suitable recipe is displayed on the touch screen 101. Then, after the recipe is selected, the door assembly 1 is opened, the food and/or ingredients are put into the glass tray 203 and/or the hardware tray 204 once and the trays are inserted into the inner cavity of the micro-steamer as prompted by the recipe, and the door assembly 1 is closed and the micro-steamer is started. Finally, the micro-steamer automatically starts a steaming mode and/or a grilling mode to cook the food. When the cooking is finished, the micro-steaming and baking machine is closed through the control system, the door assembly 1 is opened, and the cooked food is taken out.

When the micro-steamer starts a steaming mode, water drawn from the cold water tank 3 flows into the hot water tank 4, and the hot water tank 4 starts heating to generate steam. Then, the steam enters the inner cavity of the machine body component 2 through the corresponding pipe fitting to steam the food in the

trays

203 and 204, so that the steaming function of the micro-steaming and baking machine is realized. During steaming, the control system can automatically adjust the starting and stopping of the cold water tank 3 and the hot water tank 4, the steam generation rate and the like according to set conditions.

When the micro-steamer starts a roasting mode, the oven 201 installed on the rear sidewall of the body frame heats the food placed in the trays 203,204, thereby realizing the roasting function of the micro-steamer. During the baking process, the control system can automatically adjust the start, stop, heating speed, etc. of the oven 201 according to the set conditions.

The micro-steamer may further include other necessary components (e.g., electrical connections, operational controls, etc.) to perform its functions, which are well known to those skilled in the art and will not be described in detail herein.

The foregoing is illustrative of the present invention and is not to be construed as limiting thereof. It should be noted that several improvements, modifications and variations of the present invention may be made by those skilled in the art, but these improvements, modifications and variations do not depart from the spirit of the present invention and are deemed to fall within the scope of the present invention.
