Description

Heating utensil

Technical field

This utility model relates to kitchen utensils field, heats utensil in particular to one.

Background technology

Bread producing machine product in the market, as depicted in figs. 1 and 2, heating member 2' is generally single heat-generating pipe, its shortcoming is in that, when bread barrel 1' is highly higher, even heat can not be delivered to the two ends up and down of bread barrel 1' by single heat-generating pipe, thus the bread that baking is out causes that because being heated inequality the bottom of bread and top exist aberration, and then reduces the mouthfeel of bread.

Therefore, how to design a kind of height at the staving being heated higher time, it is also possible to make the heating utensil of the thermally equivalent of two ends up and down of staving become current problem demanding prompt solution.

Utility model content

This utility model is intended at least solve one of technical problem of existence in prior art or correlation technique.

Therefore, a purpose of the present utility model there are provided a kind of height at the staving being heated higher time, it is also possible to make the heating utensil of the thermally equivalent of two ends up and down of staving.

In view of this, the embodiment of this utility model first aspect provides a kind of heating utensil, including: casing, form oven cavity in described casing, in described oven cavity, be provided with staving; At least two adds heat pipe, circumferentially distributed along described staving; Wherein, adding heat pipe and include to the circumferentially extending circumferential section of described staving with along the axially extended axial direction part of described staving, and the quantity of described circumference section is multiple described in arbitrary, multiple described circumference sections are along described staving axial distribution.

The heating utensil that embodiment according to this utility model first aspect provides, adds heat pipe by circumferentially distributed multiple (at least two), heats staving simultaneously, it is possible to decrease the single power adding heat pipe, to improve the every efficiency of heating surface adding heat pipe. simultaneously, each adds heat pipe, axial (i.e. the above-below direction of staving) along staving, include multiple circumferential section being looped around around staving, and multiple circumference the axially arranged two ends up and down being dispersed in staving of the even heat of heat pipe that can add of section, from regardless of whether the height of staving how, adds heat pipe can both heat staving uniformly, to heat the food in staving uniformly. wherein, the structure adding heat pipe that this programme provides is particularly well-suited to the situation that staving is higher, such as, bread producing machine, the heating utensil such as steamed bun making machine, specifically, in the bread producing machine of such as prior art, heating element heater is single add heat pipe, thus when bread barrel is higher, add heat pipe and just can not transfer heat to the two ends up and down of staving, thus can cause that the bottom of the bread baked and top occur that color is poor, and then reduce the mouthfeel of bread, and in the application, multiple circumference section and axial direction part is included owing to adding heat pipe, therefore, add heat pipe and can even heat is delivered in the two ends up and down of staving and the circumference of staving, thus just staving can be carried out three-dimensional heating, and then bread thermally equivalent can be made, and then the bread baked not only can uniform color, and also there is good mouthfeel. simultaneously, in the application, in staving circumference, distribution has multiple (at least two) to add heat pipe, heat pipe is added with directly arranging whole around staving, multiple installation costs adding heat pipe circumferentially distributed are relatively low, install also convenient, simultaneously, homogeneous tube adds heat pipe it is difficult to ensure that the efficiency of heating surface adding heat pipe in unit length, and if, with whole add that heat pipe directly turns in the application multiple add heat pipe combined after shape, need to accomplish the power that whole adds heat pipe very big, so can cause that power and electric current are bigger, can be higher to the requirement of power panel and terminal splicing structure, and whole is added heat pipe and is divided into multiple heat pipe that adds, and utilize multiple heat pipe that adds to heat simultaneously and just do not have the problems referred to above, thus improving the overall performance adding heat pipe and heating utensil from many aspects.

Wherein it is preferred to, described in add heat pipe be metal tube, such as copper pipe.

It addition, the heating utensil in above-described embodiment of this utility model offer can also have following additional technical feature:
