Referring to fig. 1-4, the present invention provides a technical solution: the utility model provides an electric rice cooker shell that possesses heat preservation function, includes casing 1, is provided with cap 2 on the casing 1, and the last fixed surface of cap 2 is connected with handle 3, has seted up pressure release hole 4 on the cap 2, and the inside fixed connection of pressure release hole 4 is for the pressure release board 401 of fretwork form, and the inside of casing 1 is provided with holds chamber 5, and the inside that holds chamber 5 is provided with inner bag 6, is provided with insulation construction on the casing 1.

Further, the surface of the case 1 is coated with a nano-silicon coating 102.

Through the nano silicon coating 102 arranged on the shell 1, a hydrophilic coating is formed on the surface of the shell 1, namely, when water drops or dust are adhered on the outer surface of the shell 1, the hydrophilic coating can fall off under the action of self gravity, so that certain self-cleaning capability is achieved, the self-cleaning shell is not limited by the use time, and the dust-proof and water-proof effects are good.

Further, the heat preservation structure includes the insulating layer 101 that sets up in casing 1 inside, and the one side that insulating layer 101 does not contact with casing 1 is provided with heat preservation 103, and heat preservation 103 is not connected with metal reflecting plate 105 with the one side fixedly connected with of insulating layer 101 contact, and metal reflecting plate 105 coats on the one side relative with heat preservation 103 and has the heat preservation coating 104.

Through the insulating layer 101 that sets up, consequently can effectually avoid electric rice cooker to appear the electric leakage phenomenon, consequently ensure the safety in the electric rice cooker use, avoid appearing the electric phenomenon of user of service, consequently ensure electric rice cooker's normal use, improve its life simultaneously.

Further, the heat insulation layer 103 is composed of a perlite layer 1031 and a rock wool layer 1032, wherein the opposite sides of the perlite layer 1031 and the rock wool layer 1032 are respectively provided with a saw-toothed recess, and the perlite layer 1031 and the rock wool layer 1032 are mutually meshed through the saw-toothed recesses.

Through heat preservation 103 and metal reflecting plate 105 and the heat preservation coating 104 of coating on metal reflecting plate 105 that sets up, consequently make the inside of shell 1 possess good heat preservation effect, reduce its inside heat loss's speed, it is long when consequently improving the heat preservation of electric rice cooker, slow down food refrigerated speed, metal reflecting plate 105's setting simultaneously, can effectually reflect excessive heat to inner bag 6 on, and under heat preservation coating 104's setting, the heat is when contacting with metal reflecting plate 105, can slow down the heat and run off through metal reflecting plate 105, consequently, ensure the heat preservation effect to casing 1 inside, it is long when the improvement keeps warm to food.

The heat preservation layer 103 is composed of the perlite 1031 and the rock wool layer 1032 and is meshed with each other through the saw-toothed recesses of the perlite 1031 and the rock wool layer 1032, so that the connection area between the perlite 1031 and the rock wool layer 1032 is increased, the mixed effect is achieved, the overall heat preservation strength of the heat preservation layer 103 is improved, and the heat preservation effect of the shell 1 is further ensured.

Further, the pressure relief hole 4 is tapered, a sealing block 403 which is also tapered is slidably connected to the inside of the pressure relief hole 4, and a sliding groove 404 which is tapered is formed in the sealing block 403.

A tie bar 402 having an inverted T shape is fixedly connected to the lower surface of the pressure release plate 401, and one end of the tie bar 402, which is not in contact with the pressure release plate 401, is slidably connected to the inside of the slide groove 404.

Through the pressure release hole 4 that sets up, when electric rice cooker is using, when inside steam and pressure are great, its pressure and steam can make sealed piece 403 pass through connecting rod 402's support and upwards slide in the inside of pressure release hole 4, consequently sealed piece 403 is not sealing up pressure release hole 4, the inside pressure of casing 1 this moment and steam pass through pressure release hole 4 and outwards discharge, when electric rice cooker needs keep warm, its inside pressure and steam disappear, sealed piece 402 is under the state of self gravity and the inside of card again in pressure release hole 4, consequently, form sealedly to pressure release hole 4, and then avoid the inside heat of shell 1 to pass through pressure release hole 4 and outwards run off, consequently, ensure the holistic heat preservation effect of shell 1.

The working principle is as follows: through the arranged heat preservation layer 103, the metal reflecting plate 105 and the heat preservation coating 104 coated on the metal reflecting plate 105, the interior of the shell 1 has a good heat preservation effect, and the speed of heat loss in the shell is reduced, so that the heat preservation duration of the electric cooker is prolonged, and the food cooling speed is slowed down, meanwhile, the arrangement of the metal reflecting plate 105 can effectively reflect the overflowing heat to the inner container 6, and under the arrangement of the heat preservation coating 104, when the heat is in contact with the metal reflecting plate 105, the heat loss through the metal reflecting plate 105 can be slowed down, so that the heat preservation effect on the interior of the shell 1 is ensured;

through the pressure release hole 4 that sets up, when electric rice cooker is using, when inside steam and pressure are great, its pressure and steam can make sealed piece 403 through connecting rod 402's support and upwards slide in the inside of pressure release hole 4, consequently sealed piece 403 is not sealing up pressure release hole 4, the inside pressure of casing 1 this moment and steam pass through pressure release hole 4 and outwards discharge, when electric rice cooker needs keep warm, its inside pressure and steam disappear, sealed piece 402 is under the state of self gravity and the inside of card again in pressure release hole 4, consequently, form sealedly to pressure release hole 4, and then avoid the inside heat of shell 1 to outwards run off through pressure release hole 4.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
