Description

Dot pattern heater and use the bread baker of this heater

Technical field

The present invention relates to a kind of heater, be specially a kind of dot pattern heater, and the bread baker of using this heater.

Background technology

Present existing heating technique all is to heat for the area at monoblock usually, causes and can't control heating surface (area) (HS and position.

Summary of the invention

The invention provides a kind of dot pattern heater that can control heating surface (area) (HS and position, and the bread baker of utilizing this device.

A kind of dot pattern heater, it is made up of dot matrix heating plate and control module, each dot matrix heating plate is made of several little heating units and pedestal, heating unit and pedestal on each dot matrix heating plate are made by resistant to elevated temperatures insulating materials, heating unit is fixed on the pedestal, be connected with the circuit control module again, control module is made of single-chip computer control system module and strong and weak electricity modular converter, the definite dot matrix heating plate that will work of single-chip computer control system module, the make-and-break signal that sends is passed to corresponding dot matrix heating plate through the strong and weak electricity modular converter heats it.

The circuit control module is by the figure input module, single-chip computer control system module and strong and weak electricity modular converter constitute, the figure input module sends to single chip control module with the figure of required heating, single chip control module is set up corresponding plane lattice model at the dot matrix heating plate, and the heating unit on the corresponding dot matrix heating plate scans, determine the target hot spot of some correspondences, and send the beginning heating signal, this signal comprises heating-up temperature, heat time heating time, this signal is received by the strong and weak electricity modular converter, pick up counting and heat at the target heating unit, after heating is finished, single-chip microcomputer carries out correspondence scanning once more, the heating order was all carried out in so circulation, the target heating unit in corresponding flat dot matrix model.

Heating plate and pedestal selected materials are resistant to elevated temperatures insulating materials, as silica and silicate etc., the altitude range that stretches out of its heating unit is 0-20mm, and the material of extension and pedestal is the thermostable heat insulation material, and the end of heating unit then is resistant to elevated temperatures Heat Conduction Material.

Heating unit is a hollow structure, in include heating wire, rated temperature is 300-500 degree centigrade.

Heating unit has 3 * 3 at least, and its spacing scope is 7-10mm, to guarantee final graphical effect.

A kind of bread baker has at least one as the described dot pattern heater of claim 1-5, and its shell can be accommodated above-mentioned heater wherein.

The present invention can realize can editing the anticipation heating location, thereby realizing graphical heating heating surface (area) (HS and position are control effectively.

The specific embodiment

For further setting forth technological means and the effect that the present invention is taked for the technical solution problem, as follows to the foundation detailed description of the invention below in conjunction with accompanying drawing.

A kind of dot pattern heater, it is made up of dot matrix heating plate 1 and control module 2, as Fig. 1, each dot matrix heating plate 1 is arranged on the pedestal 1-2 by several little heating unit 1-1 dot matrix, heating unit and pedestal 1-2 on each dot matrix heating plate make by resistant to elevated temperatures insulating materials, are connected with control module 2 again.

As Fig. 2, control module 2 is by the figure input module, single-chip computer control system module and strong and weak electricity modular converter constitute, the figure input module sends to single chip control module with the want figure that heats, single chip control module can be at the plane lattice model of the foundation correspondence of dot matrix heating plate, and the heating unit on the corresponding dot matrix heating plate scans, determine the target hot spot of some correspondences, and send the beginning heating signal, this signal comprises heating-up temperature, heat time heating time, this signal is received by the strong and weak electricity modular converter, pick up counting and heat at the target heating unit, after heating is finished, single-chip microcomputer carries out correspondence scanning once more, so circulation, and the target heating unit in corresponding flat dot matrix model was all carried out the heating order.According to the number difference of the target hot spot of once carrying out the heating order, this device can be realized following two kinds of heating control models:

1,, realizes that promptly hot spot gets a heating by row by row timesharing heating.

2, whole PWM control heating reaches the whole effect that heats.

As Fig. 3, heating plate 1 and pedestal 1-2 selected materials are resistant to elevated temperatures insulating materials, as silica and silicate etc., its heating unit to stretch out height h scope be 0-20mm, the material of extension and pedestal is the thermostable heat insulation material, and the end of heating unit 1-1 then is resistant to elevated temperatures Heat Conduction Material, has at least on the heating plate 13 * 3 heating units are arranged, and each heating unit 1-1 spacing d scope is 7-10mm, to guarantee final graphical effect.Heating unit 1-1 is a hollow structure, in include heating wire 1-1-1, rated temperature is 300-500 degree centigrade.

A kind of application of this dot pattern heater is a bread baker 3, wherein has a dot pattern heater at least, be contained among the shell 3-1, shell matches with heating plate pedestal 1-2 and realizes fixing, and by this dot matrix heater rusk is carried out patterned baking.
