Abstract
The utility model provides an energy saving electric rice cooker, which is composed of a casing, a cover which is arranged on the casing and an inner cooker which is arranged in the casing. The energy saving electric rice cooker is characterized in that a vacuum heat insulation liner is arranged between the casing and the inner cooker; a heating device is arranged in the vacuum heat insulation liner; the utility model can enable the entire heating process to lie in a completely enclosed environment which has a favorable heat insulating property; the heat is centralized in the inner cooker completely; the outward heat convection, the heat conduction and the heat radiation can be barrier insulated effectively, hence, the heat utilization rate is raised; seventy percent of the electric energy can be saved compared with ordinary electric rice cookers; the heat-insulating property is enhanced simultaneously, and the product cost is lowered. The flavor and nutrient components of eats can be kept.
Description
The utility model relates to a kind of electric cooker, especially a kind of full-automatic energy-saving electric cooker.
Because characteristics such as existing electric cooker has regularly, outage automatically, insulation, and easy to use, save time and save trouble, safe and reliable, therefore, extremely people's welcome.But this class electric cooker all adopts resistance wire as heater element, and its heat-insulation layer also only adopts single common insulation material to make, and function singleness, therefore, heat utilization efficiency is lower, has only 50-60%, effectively saves energy can not be brought more convenience to the user.Though the product that has adopts computer control, has realized multi-functional purpose, this series products cost is higher, costs an arm and a leg, and can not be accepted by more consumers.Therefore, the electric cooker of prior art still can not satisfy people's demand.
The purpose of this utility model is to provide a kind of heat utilization efficiency height, high insulating effect, energy-conservation saving trouble, multiple functional electric cooker.
The technical solution of the utility model is: it is by shell, is located at the lid on the shell and the interior pot be located in the shell constitutes, it is characterized in that shell with interior pot between be provided with the vacuum heat-preserving courage, and be provided with heater in the vacuum heat-preserving courage.Wherein, described vacuum heat-preserving courage is formed by connecting by internal layer and skin, and is silver-plated and be evacuated between the ectonexine, is used to intercept hot conduction, thermal convection current and heat radiation, reaches best heat insulation effect; Described heater is located at vacuum heat-preserving courage inwall bottom, is provided with collet between heater and vacuum heat-preserving courage inwall, so that make heat energy only pass to the inside pot body, and can not pass vacuum heat-preserving courage laterally, raising heat utilization efficiency, saves energy.
The utility model compared with prior art has following advantage and extremely long-pending effect: because heat-insulation layer adopts the vacuum heat-preserving courage, and heater is located in this heat-insulation layer, can make whole heating process be in complete closed first, have in the environment of better heat-insulating property, heat is concentrated on the interior pot fully, second effectively intercept outside thermal convection current, heat conduction and heat radiation, therefore, greatly improved heat utilization efficiency, compare with common electric cooker, can save 70% electric energy, also improved heat-insulating property simultaneously, reduce product cost, keep food local flavor and nutrient content unchanged, and control is sensitive, simple to operate.
Fig. 1 is the normal cross-section structure chart of the utility model;
Fig. 2 is the circuit structure diagram of the utility model.
Below in conjunction with accompanying drawing the utility model is described further.
Among the figure, 1 is the pot body case, make cylinder with metal material, 2 is interior pot, makes cylinder with Pyrex, 3 is pot cover, 4 for being located at the air bleeding valve on the pot cover, and 5 for being located at the handle on the pot cover, and 7 is the vacuum heat-preserving courage, in making with glass, the cylinder of outside sandwich, silver-plated and be evacuated in its interlayer, this vacuum heat-preserving courage be located at shell 1 with interior pot between, its top edge is provided with cushion seal circle 6, the bottom is provided with rubber and plastic support pads 11, inside is provided with collet 10, and the shape of this collet shape and vacuum heat-preserving courage adapts, and is cylinder, on the inside bottom of collet, have groove, be provided with disc heater 9 in the groove, this heater is made with constant temperature heating ceramic material PTC, and is connected with outlet 12 on being located at shell by lead 8, after connecting power supply, can make heater 9 heating powers.
Among Fig. 2, PTC is a heater 9, and WK is a temperature detect switch (TDS), and D1 is Light-Emitting Diode (power supply indicator, a green), and D2 is Light-Emitting Diode (burner on light, a redness).After connecting power supply, press touch switch K1, power supply is by relay J 1 adhesive, and the locking power supply is imported, and to heater 9 power supply heating, when being heated to meal when ripe (water is done), temperature detect switch (TDS) WK starts, the block system relay power supply, J1 is discharged, and turn-off general supply, heating finishes.
Claims (3)
1, a kind of energy-saving electric cooker by shell, is located at the lid on the shell and the interior pot be located in the shell constitutes, it is characterized in that shell with interior pot between be provided with the vacuum heat-preserving courage, and be provided with heater in the vacuum heat-preserving courage.
2, electric cooker according to claim 1 is characterized in that described vacuum heat-preserving courage is formed by connecting by internal layer and skin, and is silver-plated and be evacuated between the ectonexine.
3, electric cooker according to claim 1 is characterized in that described heater is located at vacuum heat-preserving courage inwall bottom, and be provided with collet between heater and vacuum heat-preserving courage inwall.
