Abstract

The utility model discloses a heat-preservation lunch box. The heat-preservation lunch box comprises an inner container and a shell arranged outside the inner container, wherein a spacing space is formed between the bottom of the inner container and the bottom of the shell. According to the heat-preservation lunch box, the spacing space is formed between the bottom of the inner container of the lunch box and the bottom of the shell of the lunch box, so that direct contact between the inner container and the bottom of the shell is avoided, thus a heat insulation barrier is formed, and long-time heat preservation for food conserved in the inner container can be achieved.

Description

A kind of incubation canteen

Technical field

The utility model relates to daily necessities field, in particular, relates to a kind of incubation canteen.

Background technology

Lunch box is important tableware conventional in daily life, and it is for carrying prepared food, and within a certain period of time can be in job site or field prepared food is provided.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of incubation canteen of high insulating effect.

The purpose of this utility model is achieved through the following technical solutions: a kind of incubation canteen, and comprise inner bag and shell is outside the tank set, between described inner bag bottom and described outer casing bottom, be provided with clearance space.

Preferably, described outer casing bottom is provided with bracketing post, and described inner bag bottom withstands on described bracketing post.In order to bracketing inner bag, avoid inner bag to subside downwards.

Preferably, on described bracketing post, be provided with screw, the position of the corresponding institute in described inner bag bottom bracketing post is also provided with screw, and described inner bag and described shell are screwed.Utilize screw to realize locking of inner bag and shell simultaneously.

Preferably, the upper end-face edge of described inner bag outer surface is provided with defining flange, and described defining flange carries the upper end in described case peripheral wall.In order to the periphery of bracketing inner bag, preserve the existence of clearance space.

Preferably, described incubation canteen also comprises a heater, and described heater comprises the heating plate of the one deck of outer surface that is attached to described inner bag for generating heat.

Preferably, described heating plate is arranged on the bottom surface of described inner bag, and its size, shape are corresponding with the bottom surface of described inner bag.

Preferably, on described heating plate, be provided with and lock hole, the outer surface of described inner bag is provided with and described screw hole column corresponding to hole that lock, described heating plate by screw locking to the outer surface of described inner bag.

The utility model, owing to being provided with clearance space between lunch box inner bag bottom and outer casing bottom, like this, has avoided inner bag directly to contact with outer casing bottom, thereby forms a heat shield, and the food that makes to be kept in inner bag can be incubated for a long time.

The specific embodiment

Below in conjunction with accompanying drawing and preferred embodiment, the utility model is described in further detail.

As Fig. 1-Fig. 3, the present embodiment provides a kind of incubation canteen, comprising: inner bag 200 and setting shell 400 outside the tank, be provided with clearance space 700 between described inner bag 200 bottoms and described shell 400 bottoms.Described clearance space 700 has avoided inner bag 200 directly to contact with shell 400 bottoms, thereby forms a heat shield, and the food that makes to be kept in inner bag 200 can be incubated for a long time.

Shell 400 bottoms are provided with bracketing post 410, and described inner bag 200 bottoms withstand on described bracketing post 410.In order at the interior bracketing inner bag 200 of described clearance space 700, avoid inner bag 200 to subside downwards.Meanwhile, as shown in Figure 4, the upper end-face edge of described inner bag 200 outer surfaces is provided with defining flange 211, and described defining flange 211 carries in the upper end of described shell 400 perisporiums, in order to the periphery of bracketing inner bag 200, preserves the existence of clearance space.

As shown in Figure 4, lunch box is also provided with heater simultaneously, and described heater 300 comprises the heating plate 301 of the one deck of outer surface that is attached to described inner bag 200 for generating heat.

Heating plate 301 is arranged on the bottom surface of described inner bag 200, and its size, shape are corresponding with the bottom surface of described inner bag 200, from the bottom surface heating of inner bag 200, like this heating plate 301 arrange more conveniently, while heating effect is also better.Certainly, also heating plate can be attached at whole outer surfaces of inner bag 200, still, be difficult for like this processing, and bottom arranges heating plate the demand of heating can be reached.

On heating plate 301, be provided with and lock hole 302, the corresponding outer surface at described inner bag 200 is that bottom surface is provided with and described screw hole column corresponding to hole 302 202 that lock, described heating plate 301 by screw locking to the outer surface of described inner bag.Therefore because inner bag thickness is little, by screw hole column, screw 304 and lock hole 302 and lock heating plate 301 to inner bag 200 bottom surfaces, this kind of lock adhering arrangement is comparatively simple, also does not need to strengthen the thickness of inner bag.In addition, shell 400 bottoms of lunch box are also provided with corresponding with described screw hole column 202 hole or the screw 402 of locking, described screw 402 is set directly on described bracketing post 410, described inner bag 200, heating plate 301 and described shell 400 lock together by screw 304 simultaneously, a plurality of parts can be realized and being locked simultaneously by one group of screw like this, structure is relatively simple, and processing and assembling are more for convenience.

In the present embodiment, described heater 300 also comprises a control circuit (not shown) heating for controlling described heating plate 301, control circuit is used for realizing Based Intelligent Control heating, while making to heat food, can guarantee heating problems and heat time.Control circuit is arranged on a side bottom of described inner bag 200, and described inner bag 200 is provided with one for dodging the fossaperturate 201 of described control circuit, makes like this lunch box inner space enough, guarantees that the overall structure of lunch box can not increase.

Meanwhile, the lunch box in the present embodiment is also provided with for pointing out lunch box to use the indicator lamp 405 of state.And described inner bag 200 bottom one sides are provided with a fixed mount 205 for fixing described indication 405 lamps and circuit board thereof corresponding to the position of described indicator lamp 405, described shell 400 is provided with for exposing the perforate of described indicator lamp 405 corresponding to the position of described fixed mount 205.

In the present embodiment, described heating plate 301 is the METAL HEATING PROCESS sheet that heat transfer efficiency is high, and this heating plate can adopt panel beating to realize.Described inner bag 200 can be plastic cement or stainless steel.

Above content is in conjunction with concrete preferred embodiment further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
