Embodiment 1

[0037] figure 1 Shown is a schematic structural view of the steam control device of the electric steamer provided in Embodiment 1 of the present invention. The specific structure of the steam control device of the electric steamer is as follows:

[0038] The detection module 10 is used to detect the pressure of the water in the water tank of the electric steamer in real time or regularly, and generate and output the pressure electric signal;

[0039] The control module 20 is electrically connected with the detection module 10, and is used for receiving the electric pressure signal, and judging the water volume in the water tank according to the electric pressure signal.

[0040] The working principle of the steam control device of the electric steamer is as follows: the detection module 10 detects the pressure of water in the water tank of the electric steamer in real time or regularly, generates and outputs an electric pressure signal. According to the formula:

[0041] P=ρ...

Embodiment 2

[0050] On the basis of the above-mentioned embodiments, the control module preferably can determine the amount of change in the water volume in the water tank within a required period of time. For example at t 1 At time, the volume of water in the tank is V 1 , after the work unit time interval, at t 2 At time, the volume of water in the tank is V 2 , the amount of water change is ΔV=V 1 -V 2 .

[0051] On the basis of the above technical solutions, the steam control device of the electric steamer preferably further adds a steam generator. Correspondingly, the control module is also used to control the amount of water flowing into the steam generator through the variation of the water amount in the water tank to control the amount of steam in the electric steamer.

[0052] Specifically, see figure 2 , the control module 20 preferably includes:

[0053] The main control unit 21 is used to generate water intake information and steam generation information according to t...

Embodiment 3

[0071] image 3 It is a flow chart of the steam control method of the electric steamer provided in Embodiment 3 of the present invention. The method can be executed by the steam control device of the electric steamer, and specifically includes the following steps:

[0072] Step 10, real-time or regular detection of the pressure of the water in the water tank of the electric steamer, generating and outputting a pressure electric signal;

[0073] Step 20, determine the water volume in the water tank according to the pressure electric signal.

[0074] On the basis of each of the above technical solutions, after judging the water volume in the water tank, it also includes: judging the amount of change in the water volume in the water tank within the required time length.

[0075] After determining the amount of water change in the water tank within the required time length, the method further includes: controlling the amount of water flowing into the steam generator according to ...

Abstract

The invention discloses an electric steamer and a steam control device and method thereof. The steam control device comprises a detection module and a control module, the detection module is used for detecting pressure intensity of water in a water tank of the electric steamer in real time or regularly, generating a pressure intensity electric signal and outputting the same, and the control module is electrically connected with the detection module and used for receiving the pressure intensity electric signal and judging water quantity in the water tank according to the same. The pressure intensity of the water in the water tank is detected in real time or regularly, so that the problem that a steam control device of an existing electric steamer can only detect lowest water level and highest water level of a water tank and is unitary in detection result is solved, and detection on all water quantity height of the water tank and effect of accurately judging the water quantity in the water tank are realized.

Description

technical field [0001] Embodiments of the present invention relate to steam control technology, in particular to an electric steamer and a steam control device and method thereof. Background technique [0002] Using water vapor to heat, proof or cook food can make the food heated more evenly and reduce the loss of food nutrition. [0003] The steam control device of the existing electric steam box includes a water tank, a water storage box and a steam generator, and a liquid level switch used in conjunction with a float and a reed switch is used to detect the water level in the water tank. The device has a complex structure and can only detect the lowest water level and the highest water level of the water tank, and the cost will be greatly increased if multi-stage water level detection is to be realized. And this device usually can only play the effect of water shortage and overflow protection, and the detection result is relatively single. Contents of the invention [...
