CN2309683Y - Integral electric heater for use in electric warming up bag - Google Patents

Abstract

The utility model relates to an integral electric heater for use in an electric warming up bag. While the plate-shaped heat rejection cover of the electric heater in the existing electric warming up bag is in use, soup and water are slopped and are easy to leak to a heating plate, so the existing electric warming up bag is unsafe. The heat rejection cover is made of a galvanized sheet and is weak, and the mineral wool of the heat insulating material of the electric heater is not sealed well and dose not conform to the sanitary requirement. The electric heater and the warming up bag shell are integrally connected, so the overhauling and the dismounting are inconvenient. The integral electric heater of the utility model adopts a cap-shaped heat rejection cover, and soup and water are not leaked in a heater. The heat rejection cover is made of aluminum product and is durable. The heat insulating material of the electric heater is arranged in the cap-shaped heat rejection cover in a sealed mode, and the sealability is good. The electric heater is independent integration and is arranged at the bottom of the bag, and is convenient to dismount and overhaul and overcomes the defect of the prior art.

Description

Electricity is warmed up the monolithic devices electric heater in the bag

The utility model belongs to small household appliances, the kitchen small electric apparatus.

Before the utility model proposes, existing electricity warms up that electric heater has following shortcoming in the bag:

1. the dissipating cover of electric heater is plate shaped, and in use soup sprinkles leakiness in heating board, inadequately safety; Dissipating cover is a zinc coated sheet, is not durable;

2. insulation material mineral wool of electric heater etc. is poorly sealed, does not meet hygienic requirements;

3. electric heater and plastics are warmed up involucrum and are connected together, maintenance dismounting inconvenience.

Task of the present utility model provides the monolithic devices electric heater that a kind of electricity is warmed up bag, and it can overcome the deficiencies in the prior art, can be contained in special-purpose electricity and warm up in the bag, also can be contained in the common usefulness in the bag of warming up, and can be used for warm vegetable rice etc. again separately.

Main points of the present utility model are: the electric heater that the designer has designed independent monolithic devices is contained in electricity and warms up in the bag, especially makes the hat dissipating cover with materials such as aluminium, can stop effectively that water droplet enters heating board, to ensure safety.

Fig. 1 is a schematic diagram of the present utility model.

Fig. 2, Fig. 3 are the schematic diagrames of prior art.

Below in conjunction with accompanying drawing the utility model is described:

Shown in accompanying drawing 1, monolithic devices electric heater [9] is made up of hat dissipating cover [1], insulation board [2], heating board [3], insulation material [4], base plate [5], thermal insulation board [6], temperature regulating switch [7], decorative cover [8] etc.Heating board [3] is contained in hat dissipating cover [1] inner bottom part (internal upper part), in use leak down if any soup or condensate, water just outside hat dissipating cover [1], is dripped to the edge by overhead stream, can not leak to heating board [3], can guarantee that safety is (and among prior art such as Fig. 2, Fig. 3, after draining to water on the plate shape dissipating cover [10], just might drain to reverse side, drip in the heating board [3], so both dangerous, perishable again heating board [3]).This hat dissipating cover forms with materials processings such as aluminium, more durable (prior art plate shape dissipating cover [10] is made of zinc coated sheet, is not durable); The utility model insulation material [4] is encapsulated in the hat dissipating cover [1], and sealing better; This monolithic devices electric heater [9] is independently, and it is installed in electricity with bolt [11] and warms up bag [12] bottom.

Claims (1)

1. A kind of electricity is warmed up the monolithic devices electric heater in the bag, form by dissipating cover [1], insulation board [2], heating board [3], insulation material [4], base plate [5], thermal insulation board [6], temperature regulating switch [7], decorative cover [8] etc., it is characterized in that dissipating cover [1] is processed into hat, heating board [3] is contained in its inner bottom part, and insulation material [4] is encapsulated in the hat dissipating cover [1].
