Description

The Miniature rice cooker of simple structure

Technical field

The utility model relates to a kind of Miniature electric rice cooker, particularly a kind of Miniature rice cooker of simple structure.

Background technology

Existing Miniature rice cooker, comprises outer pot, inner bag and electric heater unit, and electric heater unit is PTC heater, and PTC heater is by fixation kit, and be arranged on inner bag diapire, that is: inner bag and PTC heater are for being fixedly connected with; During work, PTC heater heating power, transfers heat to inner bag diapire.

But, the Miniature rice cooker calandria mounting structure of above-mentioned traditional structure, have the following disadvantages: (1) PTC heater is fixed on inner bag diapire, inner bag can not take out, inner bag only heats (heat trnasfer) by bottom PTC heater, and heat also easily scatters and disappears toward surrounding, so, the electric cooker of conventional P TC heating is heated uneven, and the thermal efficiency is lower; (2) in view of inner bag periphery heat easily scatters and disappears, and heating concentrates on bottom inner bag, and this heating is uneven, has a strong impact on by the mouthfeel of cooking food; Even because inner bag diapire is connected with Kick type temperature controller, and inner bag diapire Yin Wendu is too high, the too early power-off protection of temperature controller, causes the food on the inner bag top away from inner bag diapire not boiled, and makes food cause wave useless; (3) being fixedly connected with between inner bag with PTC heater, had both caused and had installed trouble, again because inner bag can not take out separately, caused certain inconvenience to routine use; (4) be connected by fixation kit between inner bag with PTC heater, its fixation kit comprises and is welded on the bolt bottom inner bag and the hold-down nut etc. for coordinating with bolt, because needs to be burn-on bolt at inner bag diapire, its complex process, difficulty is higher, and often easily causes bolt to get loose because not prison welding is solid.

Utility model content

The purpose of this utility model is the deficiency overcoming the existence of above-mentioned prior art, and provide a kind of simple and reasonable for structure, inner bag and electric heater unit are separate type, inner bag can take out use separately, and homogeneous heating, heat not easily scatters and disappears, and significantly improves the thermal efficiency, and, simple and easy, the rational Miniature rice cooker of the supporting construction of heater.

The purpose of this utility model is achieved in that

The Miniature rice cooker of simple structure, comprise outer pot, middle level, inner bag and electric heater unit, outer pot inside is provided with middle level, middle level is provided with inner chamber, it is characterized in that, described electric heater unit comprises heat conduction pallet and electric heating body, heat conduction pallet is arranged on the inner chamber bottom in middle level, electric heating body is connected to heat conduction tray bottom, inner bag is arranged on the inner chamber in middle level and comes close to or in contact with heat conduction pallet, the inwall of described outer pot extends supporter, and supporter is provided with mat piece, and mat piece contacts with electric heater unit or middle level diapire; The Miniature rice cooker of this kind of simple structure, by the inside at outer pot, middle level is set, the inner chamber bottom in middle level is provided with the electric heater unit of heat conduction pallet and electric heating body formation, and above heat conduction pallet inner bag being placed in middle level inner chamber, make heat concentrate on middle level inner chamber, while preventing heat easily to scatter and disappear, both made inner bag be heated evenly, avoid the food of inner bag local not boiled, significantly improve the thermal efficiency again; Further, in view of between electric heater unit with inner bag for disassembled contacts, both avoided both because being fixedly connected with, cause the deficiency that inner bag can not take out, make full use of again its tray area wide, heat is along pallet both sides toward rising, inner bag periphery is heated evenly, cooks the food of taste good; And whole electric heater unit or comprise middle level, is supported by easy supporter and mat piece thereof together, mat piece plays heat insulation and effect that is shock-absorbing simultaneously, so, whole money Miniature rice cooker simple and reasonable for structure.
