Example 2

The structure of the energy-saving steaming furnace with independently controlled steaming holes in the embodiment 2 is the same as that in the embodiment 1. This embodiment is a preferred embodiment for the steam control valve 5: the steam control valve 5 is an electromagnetic control valve 52.

Because the steam control valve 5 in embodiment 1 is the mechanical control valve 51, and the mechanical control valve 51 repeatedly moves during working, the situations of incomplete movement, deformation of a switch, and gap and loose closing inside easily occur after long-term use, so that the use experience of a user is influenced, and the energy saving performance of the steam stove is also influenced. For this reason, the steam control valve 5 in the present embodiment 2 is the electromagnetic control valve 52.

As shown in fig. 9 and 10, the upper end of the solenoid-operated valve 52 is provided with an induction switch, and when a user places a steaming vessel into the steaming hole 321, the lower surface of the steaming vessel is close to the induction switch of the upper end of the steam control valve 5, the solenoid-operated valve 52 is communicated accordingly, so that steam can be discharged to the steaming hole 321 through the diverging assembly 4, thereby performing steaming. When the user withdraws the steaming vessel from the steaming hole 321, the lower surface of the steaming vessel is away from the inductive switch of the upper end of the steam control valve 5, and the electromagnetic control valve 52 is correspondingly closed, so that the steam cannot flow through the flow dividing assembly 4, and the steaming hole 321 no longer discharges the steam.

The electromagnetic control valve 52 is controlled to be opened and closed by electrifying the electromagnet and can be automatically reset by an internal spring, and the induction switch is not easy to deform due to the reciprocating movement caused by long-term use, so that the motion reliability of the steam control valve 5 is higher. In addition, the system structure of the electromagnetic control valve 52 is simple, and the electromagnetic control valve can be connected with a computer or other control circuits for use, so that the application range is wide, and the cost is low.

Example 3

The structure of the energy-saving steaming furnace with independently controlled steaming holes in the embodiment 3 is the same as that in the embodiment 2. This embodiment is a preferred embodiment for the steam control valve 5: the steam control valve 5 is an electrically controlled valve 53.

Since the steam control valve 5 in embodiment 2 is the solenoid control valve 52, since the solenoid control valve 52 has a fixed working position, it can only be completely opened or completely closed, and when a user needs to control the opening and closing degree, the solenoid control valve 52 cannot meet the use requirement. For this reason, the steam control valve 5 in the present embodiment 3 is an electric control valve 53.

As shown in fig. 11 and 12, the electric control valve 53 drives the valve to open and close through the rotation of the motor, and the opening and closing degree can be adjusted according to the actual use condition, so that the flow of steam can be controlled, and when a user needs to quickly steam, the electric control valve 53 is completely opened, and the steam flow is maximum; when the user desires to slowly steam, the opening degree of the electric control valve 53 is decreased, and the steam flow rate is decreased accordingly. The user can use one of a knob switch and a push-button switch arranged on the steaming stove to adjust the opening and closing degree of the electric control valve 53.

Through adopting electric control valve 53 for the user can further carry out independent control to the steam flow of evaporating hole 321, and the user can select different steam flow according to different food, and then influences the steaming time, thereby makes the application scope of steam ager wider.

Example 4

This embodiment is a preferred configuration for the diverter assembly 4: the flow distribution assembly 4 is of a bifurcated pipeline structure, and the flow distribution assembly 4 does not comprise a connecting bin 44.

In the embodiment 1, the pipes in the flow distribution assembly 4 are connected through the connecting bin 44, so that in the production process of the steam oven, more materials are needed for manufacturing the flow distribution assembly 4 with the connecting bin 44, the manufacturing process is complex, and the production cost is high.

For this reason, in the present embodiment 4, the flow dividing assembly 4 does not include the connecting cabin 44, and the air inlet duct 41 is directly and fixedly connected with the flow dividing duct 42 and the air outlet duct 43. In this embodiment, the air inlet pipe 41, the shunt pipe 42 and the exhaust pipe 43 are connected by welding, so that the pipes are tightly and stably connected by welding, and the production cost is low.

In the embodiment 4, the direct connection mode among the air inlet pipeline 41, the branch pipeline 42 and the exhaust pipeline 43 is adopted instead of the mode of arranging the connecting bin 44 to connect the air inlet pipeline 41, the branch pipeline 42 and the exhaust pipeline 43, so that the production cost is greatly reduced, and the embodiment 4 is also suitable for the embodiments 2 and 3.

Other structures of the energy-saving steaming furnace with independently controlled steaming holes are disclosed in the prior art.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, so that any modification, equivalent change and modification made by the technical spirit of the present invention to the above embodiments do not depart from the technical solution of the present invention, and still fall within the scope of the technical solution of the present invention.
