SUMMERY OF THE UTILITY MODEL

In view of this, the utility model provides a but segmentation accuse temperature's water-bath can realize segmentation accuse temperature, convenient and practical.

In order to solve the problems in the prior art, the technical scheme of the utility model is that the water bath kettle capable of controlling temperature in a segmented mode comprises a kettle body, wherein a kettle cover is arranged on the kettle body, support legs are arranged at the bottom of the kettle body, a water inlet pipe and a water outlet pipe are arranged on the kettle body, a heat conducting plate is arranged at the bottom of the kettle body, a plurality of heating pipes are arranged at the bottom of the heat conducting plate, and a temperature sensor and a liquid level sensor are arranged in the kettle body.

The heating pipe is a U-shaped heating pipe.

The model of the singlechip is AT 8951.

Compared with the prior art, the utility model has the advantages as follows:

the utility model has the effect of sectional temperature control, and the principle of the built-in circulating water system greatly reduces the waiting time of the water temperature in the water bath from high temperature to low temperature;

the control box in the structure of the utility model reduces the operation steps of the experimenter in the sectional control;

the utility model discloses the setting up of level sensor, check valve, control box in the structure makes the utility model discloses have experimental back automatic water supply function, reduced the moisturizing operation of experimenter at the second time use water bath.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The embodiment provides a water bath kettle capable of controlling temperature in a segmented manner (see fig. 1 and 2), which comprises a kettle body 1, wherein a kettle cover 2 is arranged on the kettle body 1, and support legs 7 are arranged at the bottom of the kettle body 1.

The pot body 1 is provided with a water inlet pipe 3 and a water outlet pipe 4; the water inlet pipe 3 is provided with a first one-way valve 31, and the water outlet pipe 4 is provided with a second one-way valve 41;

the bottom of the pot body 1 is provided with a heat conducting plate 13, the bottom of the heat conducting plate 13 is provided with a plurality of U-shaped heating pipes 14,

a temperature sensor 12 and a liquid level sensor 11 are arranged in the pot body 1;

a control panel 6 is arranged on the outer wall of the pot body 1, and an operation panel 61 and an L ED display screen 62 are arranged on the control panel 6;

the pot body 1 is further provided with a control box 5, a single chip microcomputer and an A/D conversion module are arranged in the control box 5, the single chip microcomputer is connected with the A/D conversion module, and the single chip microcomputer is AT8951 in model.

The utility model discloses a working process:

the temperature required for the experiment and the time for which the temperature is to be controlled stepwise are adjusted by the operation panel 61.

For example: the experiment is divided into 2 stages at constant temperature, wherein the temperature of the first stage is 90 ℃, the constant temperature time is 2 hours, the temperature of the second stage is 60 ℃, and the constant temperature time is 1 hour. After the adjustment, the heating pipe 14 starts to work, and after the temperature sensor 12 detects that the temperature reaches 90 ℃, the heating pipe stops working, and then the temperature is kept constant for 2 hours.

After the first experiment stage is finished, the control box 5 sends a signal command, the first one-way valve 31 and the second one-way valve 41 are opened simultaneously to supply water into the water bath kettle, the water circulation in the kettle body 1 is realized, the effect of rapid cooling is achieved, when the temperature detected by the temperature sensor 12 reaches 60 degrees, the control box 5 sends a command, the one-way valves are closed simultaneously, and the second experiment stage of keeping the temperature for 1 hour and 60 degrees is started. (if the experiment subsection is carried out from low temperature to high temperature, the heating pipe 14 starts to work only by the control box 5 sending an instruction to the heating pipe, and the effect of temperature rise in the second stage can be achieved)

After the experiment is finished, when the liquid level sensor 11 detects that the water in the pot body 1 is lower than the set line, the control box 5 sends an instruction to the first one-way valve 31 to supply water, so that the water adding operation before the second experiment is reduced.

The utility model discloses a circulating water cooling principle can also change into and set up the cooling fin on 1 inner walls of pot body, reaches rapid cooling's effect.

The utility model discloses an in the course of the work, behind the control box 5 received the signal that temperature sensor 12, level sensor 11 and control panel transmitted, through signal processing (AD conversion module), the singlechip received the signal and goes control governing valve or heating pipe to reach the experiment effect.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention.
