The invention discloses a cooling system of an integrated cooker or an electric oven body. The cooling system comprises a cooling mechanism and a two-layer door sheet structure, wherein the cooling mechanism is arranged on an inner top plate of the oven body; the door sheet structure is arranged in front of the oven body; the cooling system has the advantages that a row of vent holes is formed ineach of an upper connecting plate and a lower connecting plate of the two-layer door sheet structure in front of the oven body; an exhaust passage of the cooling mechanism sequentially communicates with a thermal insulating cavity between door sheets and an external space at the bottom of the oven body through the vent holes in the upper connecting plate and the lower connecting plate; after the cooling mechanism exhausts the warm air in the oven body, the warm air enters the external air from the air inlet of a rear sheet to reduce the temperature in the oven body, and the exhausted warm airis discharged into the external space at the bottom of the oven body from the exhaust passage and the thermal insulating cavity and does not directly blow to the crotch of people, so that kitchen staff can stand in front of the electric oven body for operation safely for a long time; the temperature of the warm air flowing through the thermal insulating cavity is relatively low, so that the temperature of the door sheet on the outer layer can be reduced, the door sheet on the outer layer is kept in the warm state, and the people are not scalded if touching the door sheet by accident.

The present invention relates to a cartridge fuse and a manufacturing technique for the cartridge fuse, in particular to a vacuum cartridge fuse and a manufacturing technique for the cartridge fuse. The interior of main body of the cartridge fuse is in vacuum state. The present invention utilizes high frequency welding technique to solder a fuse, a tube, and a tinned copper cap together as follows: high frequency current is provided by a high frequency welding machine, an enclosed soldering cavity that can be opened is arranged, alternating magnetic field is produced by the high frequency current in the enclosed soldering cavity, the frequency and time of the high frequency current is controlled, so that the tin on the tinned cap is melted and therefore the soldering is completed in the enclosed soldering cavity. The copper cap on one end is soldered with high frequency welding technique; before the other end is soldered, the cavity is pumped into vacuum state to attain the purpose ofprotecting the finished product of cartridge fuse.

The invention relates to an environmental-friendly steam pipeline drainage collection system and a working method. The environmental-friendly steam pipeline drainage collection system comprises a warehouse chamber for being arranged underground and capable of allowing the cooling water t be injected, a partition plate is arranged in the warehouse chamber, the warehouse chamber is divided into a mixed temperature warehouse and a draining warehouse by the partition plate, the mixed temperature warehouse and the draining warehouse communicate with the gaps in the bottom faces of the warehouses through the partition plate respectively, at least one drainage pipe is connected with the mixed temperature warehouse and used for being connected with the drainage point of a steam pipeline, the drainage pipe can guide the drainage in the steam pipeline into the mixed temperature warehouse, the draining warehouse is connected with a blowdown well through an inverted-U-shaped overflow pipe, the water in the draining warehouse can be drained into the blowdown well, an emptying pipe extending beyond the ground at the set height is further connected with the draining warehouse, and the emptying pipe is used for exhausting the excess fog in the draining warehouse. The environmental-friendly steam pipeline drainage collection system can be arranged in place, the scope of the application is wide,and the safety and environment of the plant can be ensured.

The invention discloses a heat insulation sinking type stove. The heat insulation sinking type stove comprises a stove body and a support. The stove body comprises a groove, a primary stair and a secondary stair are arranged in the groove, and the support is movably put on the secondary stair. The support comprises two pot support bodies and a middle frame, and the middle frame is located between the two pot support bodies. The two side walls of each pot support body are each provided with two first heat insulation bodies, first landing legs are arranged on the bottoms of the pot support bodies, and second heat insulation bodies are arranged on the outer sides of the first landing legs. Second landing legs are arranged on the bottom of the middle frame, and third heat insulation bodies are arranged on the outer sides of the second landing legs. The first heat insulation bodies, the second heat insulation bodies and the third heat insulation bodies are each in a spherical shape and are made of heat insulation materials. According to the heat insulation sinking type stove, point contact is adopted between the support bodies and between the support and the stove body, heat transmission among the components is reduced, and therefore the temperature of the stove body and the temperature of the middle frame are reduced, people cannot be scaled when making contact with the stove body and the pot support bodies during cooking, and people can use the stove conveniently.

The invention relates to a visible steam cooking device used together with heating cooking equipment cooperatively. The visible steam cooking device comprises a pot cover, a stone pot, a steam heating device and a heating flange plate and is characterized in that the heating flange plate comprises a fixed flange plate and a movable flange plate; the heating flange plate is covered by the pot cover; and the stone pot is arranged in the pot cover. The visible steam cooking device has the advantages and effects that in the heating process, diners can see the whole cooking process and changes of the color and shape of food to have better dining feelings; the pot cover can be controllably opened, thus preventing the diners from opening the pot cover by hands; and therefore scalds can not be caused.
