The structure has a large amount of steam generation, uniform distribution of steam, and good taste of food after cooking. But the produced steam is still not used for other purposes, it is necessary to further improve and perfect.

Utility model content

The purpose of the utility model is to provide a multifunctional microwave oven with simple and reasonable structure, convenient use and multipurpose steam heating, so as to overcome the shortcomings in the prior art.

A multifunctional microwave oven with steam heating designed according to this purpose, including a furnace body, a control panel and an electric heating steam generator installed in the furnace body, its structural feature is that the steam outlet pipe of the steam generator is connected with an external nozzle mechanism.

There are two joints on the steam generator, one of which is a steam outlet pipe, which is connected with a two-position three-way solenoid valve to control the flow direction, one line leads to the inner tank for heating food, and the other line is connected to the external nozzle mechanism; One joint is a water outlet pipe connected with a one-way solenoid valve connected to the front end of the air outlet pipe through a three-way pipe.

The external nozzle mechanism includes a two-way valve, one end of which is connected to the end of the steam outlet pipeline, and the other end is connected to the nozzle; or a three-way valve, which is respectively connected to the end of the steam outlet pipeline, the beverage pipe and the nozzle.

The external nozzle mechanism is arranged on the outside of the inner container, and the nozzle mechanism is arranged on the outer decorative cover, which can be pushed and pulled out, and is provided with a hinged flip cover to hide the nozzle mechanism.

The utility model makes full use of the function of the steam generator, perfects the function of the microwave oven, passes steam or boiled water to the outside to make milk, soybean milk, etc., and plays a stirring role. At the same time, there is no special requirement for the material of the water cup, which is convenient for users to use at will; The retracted nozzle can be hidden well to keep it beautiful, and it is safe and reliable; the exported steam can also be used for humidifying the iron, cleaning the container, disinfecting and sterilizing, etc., which is very practical.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is described further.

Referring to Fig. 1-Fig. 4, this multifunctional microwave oven with steam heating includes a furnace body, a control panel and an electric heating type steam generator 1 arranged in the furnace body. There are two joints on the steam generator, one of which is the outlet The steam pipeline is connected with a two-position three-way solenoid valve 2 for controlling the flow direction, one way leads to the inner tank 14 for heating food through the nozzle 13, and the other way is connected to the external nozzle mechanism; the other joint is the water outlet pipe, and the water outlet pipe passes through the connector 5 is connected with the steam generator, and is connected with a one-way solenoid valve 4, and is connected with the front end of the air outlet pipe through the three-way pipe 3. The external nozzle mechanism 6 includes a three-way valve 8, which is respectively connected to the end of the steam outlet pipe, the beverage pipe 7 and the nozzle 9 (also can be designed as a two-way valve). The steam generator 1 is connected with a water pump and a water box 16 in sequence, and the water pump and the water box are arranged at the rear bottom of the control panel. A sealing ring is arranged on the joint of the steam outlet pipe. The nozzle mechanism 6 is arranged on the outer decorative cover 11 outside the inner tank 14, which can be pushed in and pulled out, and a hinged flip cover 10 is provided to hide the nozzle mechanism 6. The top of the furnace body is also provided with exhaust holes 12 .

The working principle of the utility model is as follows:

1. Steam injection function: the program on the control panel controls the on-off time of the water pump and the direction of the three-way solenoid valve 2; when the button 15 on the control panel is pressed once, the water pump circulates with the program of pumping for 2 seconds and stopping for 18 seconds to discharge the water. The water in the box 16 is pumped to the steam generator 19 (see arrow A in Figure 3) to generate high-temperature steam, which is guided to the three-way solenoid valve 2 through the steam outlet pipe (see arrow B in Figure 3), and the three-way solenoid valve is pressed Just energize and hit the direction of nozzle mechanism 6 when pressing a button, and steam leads to nozzle 9 along the outlet pipeline, and is sprayed in the water cup that places under high pressure. At the same time, a negative pressure is formed at the three-way solenoid valve 2, and the cold milk in the beverage pipe 7 is pumped to the three-way valve 8, and mixed with high-temperature steam, which not only achieves the effect of heating the milk, but also stirs the milk uniform.

2. The function of spraying water: when the button 15 on the control panel is pressed twice, the water pump will circulate with the program of pumping for 5 seconds and stopping for 15 seconds, pumping the water in the water box 16 to the steam generator 1 and heating it to a certain temperature, and the water level will continue It rises, flows out when it exceeds the steam outlet, and leads to the one-way solenoid valve 4 through the outlet pipe (see arrow C in Figure 3). The three-way pipe leads to the nozzle 9, and is sprayed into a placed water cup under high pressure to make tea or coffee.

Before using the nozzle, first open the flip cover 10, pull the nozzle mechanism 6 out to a certain position, and align it with a water cup placed at a certain height on the side of the microwave oven; after use, push the nozzle mechanism 6 back and cover the flip cover.
