Description

Electric heating lunch box

Technical Field

The invention relates to the technical field of portable tableware, in particular to an electric heating lunch box.

Background

The electric heating lunch box is used as common tableware, and the demand of users for the electric heating lunch box is increasing. At present, most of electric heating lunch boxes are composed of a lunch box body and a lunch box cover, and parts such as an electric heating generator and the like are arranged in the electric heating lunch box. These electric heat lunch-box can heat, keep warm the effect, but it has certain defect: because the lunch-box is sealed, its internal environment all is in the heating environment. When the electric heating lunch box has a steam heating function, the electric heating lunch box is generally provided with a steaming rack which is supported in the lunch box. The steaming rack can separate the inner space of the lunch box, so that food can be stored in the upper layer of space and the lower layer of space of the steaming rack.

However, the steaming rack is heated along with the food, so that the temperature of the steaming rack is too high after the heating lunch box is opened, and at the moment, if the food below the steaming rack needs to be directly touched and the steaming rack needs to be lifted up and taken out, a user can easily scald the steaming rack with too high contact temperature. After the steaming rack is cooled, the temperature of food below the steaming rack is also reduced, and the taste of the food is affected.

The protruding parts are distributed in an annular shape, and support grooves are formed in the steaming rack in an enclosing mode.

One side of the protruding portion, which is close to the supporting groove, is an arc-shaped surface, and an extension line of the protruding portion in the second state is intersected with a plane where the water collecting portion is located.

The base module further includes:

and the second shell is supported on the first shell, and the heating space is formed between the second shell and the cover body.

The second shell is embedded into the first shell, at least one side wall of the second shell is obliquely arranged to form an inclined surface, the inclined surface faces the first shell and forms an installation space between the first shell, and the placement groove is located in the installation space.

The water collection box comprises:

the closed end, the water collecting part is arranged on the closed end, and the closed end is used for sealing the opening of the placing groove.

The steaming rack further comprises:

the holding part is arranged on the movable end of the steaming rack, and a heat insulation layer is arranged on the holding part.

The grip portion includes: the handle is rotatably connected to the steaming rack.

The technical scheme of the invention has the following advantages:

1. the invention provides an electric heating lunch box, comprising: a base module; the cover body is arranged on the base module in a matched mode, and a heating space is formed between the cover body and the base module; the steaming rack comprises a switching end and a movable end, the steaming rack is rotatably connected to the base module through the switching end and is positioned in the heating space, and the steaming rack has a first state of separating the heating space and a second state of rotating to be far away from the heating space.

The base module is as the main part that supports of whole electric heat lunch-box, and the base module not only can cooperate the lid to form heating space, and the base module can also be suitable for holding parts such as installation heating element, circuit structure and control module. The steaming rack is supported on the base, the heating space inside the electric heating lunch box is divided into two layers, and food can be respectively placed in the upper and lower layers of spaces of the steaming rack for heating. After the food is heated, the food above the steaming rack can be directly taken down, and then the steaming rack is rotated without lifting up the whole steaming rack to take out the food. The pivoted action is owing to have the switching end to provide certain support, for the process that raises the steam rack among the prior art, carries to draw and draws the expansion end and need relatively less power, has reduced the requirement of exerting oneself to opening the steam rack on the one hand, on the other hand can reduce the area of contact's with the steam rack demand to reduce the risk that user's hand was scalded. The steaming rack of the further scheme can be supported by the rod body to be pried and turned without being contacted by hands. Meanwhile, the steaming rack is opened by applying acting force on the movable end, so that the manufacturing material of the movable end can be replaced by materials such as silica gel, or an additional coating which is not easy to heat up is arranged.

2. The invention provides an electric heating lunch box, which further comprises: the water collecting box is arranged on the base module and comprises a water collecting part, and when the steaming rack is in the second state, the extension line led out from the surface of the steaming rack passes through the water collecting part.

The steam rack is in the use, and a large amount of condensate water can be attached to the surface of the steam rack, and when the steam rack is opened by taking the rotating end as a rotating center, water on the surface of the steam rack is gathered and flows to the rotating end of the steam rack. The steaming rack surface in this scheme mainly refers to two relatively large surfaces of area towards base module and lid on the steaming rack. When the extension line led out from the surface of the steaming rack passes through the water collecting part, water flows along the surface of the steaming rack and continues to flow along the extension line of the surface of the steaming rack after being separated from the surface of the steaming rack, so that condensed water on the steaming rack can be accurately collected by the water collecting part.
