Embodiments of the invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the drawings are intended to be illustrative of the invention and are not to be construed as limiting.

A microwave oven 100 according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

Referring to FIGS. 1 through 4, a microwave oven 100 according to an embodiment of the present invention may include a furnace body 20, a water tank assembly 10, a drive assembly 30, a controller, and a steam generator 40.

In particular, a cooking cavity can be defined within the shaft 20. The water tank assembly 10 can include a water tank body 11 that is movable between an open position and a closed position. The water tank body 11 may define a water storage chamber. The water tank body 11 may be provided with a water inlet 101 and a water outlet 102. The water inlet 101 and the water outlet 102 may respectively communicate with the water storage chamber. The steam generator 40 may be disposed on the furnace body 20. The steam generator 40 may be provided with a water inlet and a steam outlet, and the water inlet It can be in communication with the water outlet 102, which can be in communication with the cooking chamber.

Therefore, when water is needed, the water tank body 11 can be placed in an open position, water is added to the water storage chamber through the water supply port 101; when the water is added, the water tank body 11 can be placed in a closed position, and the water in the water storage chamber can pass through. The nozzle 102 flows out and flows into the steam generator 40 from the water inlet, and the steam generated in the steam generator 40 can flow out through the steam outlet and flow into the cooking chamber to realize steam heating of the food, etc., and the cooking effect is good.

The drive assembly 30 can be disposed on the shaft 20, and the drive assembly 30 can have a drive portion that can be moved to stop and urge the water tank body 11 to move toward the open position when the drive assembly 30 is in operation. The controller can be coupled to the drive assembly 30 to control the drive portion to urge the water tank body 11 to move toward the open position.

Therefore, when it is necessary to add water to the water tank body 11, the controller can control the operation of the driving assembly 30, so that the driving portion can stop and push the water tank body 11 from the closed position to the open position, and the water tank body 11 can be automatically opened. No need to open the force by hand, the operation is convenient and labor-saving, the performance is good, and the user experience is good.

For convenience of operation, optionally, the furnace body 20 may be provided with a control switch, and the control switch may be connected to the controller. When the control switch is open, the controller can control the operation of the drive assembly 30 to move the water tank body 11 to the open position. The control switch may be formed as a control button or a control button or the like, and the control switch may be disposed at different positions of the shaft 20 as needed. For example, the control switch may be disposed on the front side of the shaft 20 for easier operation.

According to some embodiments of the invention, the controller is configured to control the operation of the drive assembly 30 to reset the drive portion after a predetermined time of movement of the water tank body 11 from the closed position to the open position. Here, it should be noted that the driving portion has an initial position and an active position, and when the driving portion is in the initial position, the water tank body 11 may be in the closed position, and the microwave oven 100 may be in a normal state or a cooking state. When the drive assembly 30 is in operation, the drive portion will move, no longer in the initial position, and the position at which the drive portion is located can be understood as the active position, and the reset of the drive portion can be understood as the drive portion moves from the active position to the initial position.

Thus, when the water tank body 11 is automatically opened by the driving assembly 30, the driving portion can automatically return to the original initial position under the control of the controller; when the watering is completed, the user can push the water tank body 11 back to the closed position.

The second microswitch 42 is closed or opened and a bit signal is sent to the controller, and the controller receives the bit signal in a standby state.

Here, the "standby state" of the controller can be understood as the controller is in a receivable signal, and can output corresponding control commands according to the received signal to control other components to work. For example, the controller can receive the cooking signal and control the steam generation. The device 40 steams or controls the microwave generator to emit microwaves to effect steam heating or microwave heating of the food. When the water tank body 11 is not in the closed position, the controller is no longer in the standby state. When the controller sends a signal, the controller can receive the signal, but does not perform the control function corresponding to the signal, but reports an error or warning externally. The user closes the water tank body 11.

When the water tank body 11 is moved to the closed position, the water tank body 11 can stop against the second micro switch 42 so that the switching state of the second micro switch 42 can change state, for example, open or close, and the first micro motion The switch 41 can generate an in-position signal to the controller. After receiving the in-position signal, the controller can adjust to the receivable signal and issue a control command corresponding to the signal to implement control of the corresponding component.

Thus, when the water tank body 11 is not in the closed position, the microwave oven 100 will not be able to implement functions such as cooking, and the use safety is good. As shown in FIG. 7, a stopper piece 112 may be disposed on the tank body 11. When the tank body 11 is in the closed position, the abutment piece 112 may protrude out of the casing 12 and rest on the second micro switch 42.

The inner tube portion 1211 is bored in the elastic slit 1421 of the sealing cover 142, and the inner opening portion 111 and the outer opening portion 121 are in a conductive state.

At this time, when the water adding operation is required, the control switch can be turned on, the controller controls the motor 31 to rotate in the forward (or reverse) direction, the gear 32 rotates counterclockwise, the rack 33 moves forward, and the front end of the rack 33 extends into the shell. The escaping port 104 on the body 12 abuts against the water tank body 11 and pushes the water tank body 11 forward, the water tank body 11 is separated from the second micro switch 42, the controller is no longer in a standby state, and the controller cannot perform some control. Features such as cooking features.

When the water tank body 11 is moved to the open position, the controller controls the motor 31 to stop rotating, and at this time, the water tank body 11 is in the open position, and water can be added to the water storage chamber through the water supply port 101. At this time, the inner tube portion 1211 can be removed from the elastic slit 1421 of the sealing cover 142, so that the sealing cover 142 can seal one end of the inner opening portion 111 so that water added in the water tank body 11 does not flow out from the inner opening portion 111.

From the time when the tank body 11 is moved to the open position, after a predetermined time elapses, for example, 3s or 5s, the controller automatically controls the motor 31 to rotate in the reverse direction (forward), the gear 32 rotates clockwise, and the rack 33 moves backward. When the rack 33 is moved to the initial position, the rack 33 is in contact with the contact of the first micro switch 41, the first micro switch 41 is closed (or opened), and the first micro switch 41 is issued to the controller. The stop signal, the controller receives the stop signal, and the control motor 31 stops rotating, so that the rack 33 can stay in the initial position to achieve reset. During this process, the tank body 11 remains in the open position.

Wherein, after the water is added, the user can apply a force to the water tank body 11 to move the water tank body 11 toward the closed position. When the water tank body 11 is moved to the closed position, the water tank body 11 can stop against the contacts of the second micro switch 42, the second micro switch 42 is closed (or opened), and an in-position signal is sent to the controller. The controller receives the in-position signal and is in a standby state, can receive signals and perform functions such as cooking, and is safe and reliable to use.
