Detailed Description

The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings. It is to be understood that the description of the embodiments herein is for purposes of illustration and explanation only and is not intended to limit the invention.

Example 1

As shown in fig. 1, the present embodiment discloses a water level detecting structure, which includes at least a first probe 1 and a second probe 2, wherein the first probe 1 is provided with a vertical height lower than that of the second probe 2. The detection principle is as follows: when the water level is lower than the second probe 2 and higher than the first probe 1, a temperature difference is generated between the first probe 1 and the second probe 2, and when the temperature difference is greater than or equal to a set value, the water level is judged to be between the first probe 1 and the second probe 2.

It can be understood that the vertical height difference between the first probe 1 and the second probe 2 determines the detection accuracy of the water level detection structure, i.e. the smaller the vertical height difference is, the higher the detection accuracy is; when the vertical height difference between the first probe 1 and the second probe 2 tends to 0, the temperatures of the first probe 1 and the second probe 2 are approximately equal, and the detection function cannot be realized. Therefore, in practical applications, the vertical height difference between the first probe 1 and the second probe 2 may be set within an allowable error range. For example, in a small volume kettle application, the vertical height difference between the first probe 1 and the second probe 2 may be set between 1-10 mm.

It should be noted that the water level detecting structure can detect the water level at any position according to different positions. For example, when the first probe 1 is disposed below the 80% water line and the second probe 2 is disposed above the 80% water line, it can be used to detect the 80% water level of the heating container; similarly, when the first probe 1 is disposed below the 50% water level line and the second probe 2 is disposed above the 50% water level line, it can be used to detect the 50% water level of the heating container.

As shown in fig. 2, the device further includes more than one third probe, the vertical heights of the third probes 3 are sequentially set from low to high, and the third probe 3 with the lowest vertical height is higher than the vertical height of the second probe 2. At this time, the water level detecting structure can detect more than two water levels. For example, when there is one third probe 3, the first probe 1 may be disposed below the 50% water line, the second probe 2 may be disposed above the 50% water line and below the 80% water line, and the third probe 3 may be disposed above the 80% water line, which may be used to detect the 80% water level and the 50% water level of the heating container.

Example 2

This embodiment is a specific application of the water level detection structure described in embodiment 1 for use as a judgment when the heating container is empty of water, i.e., a 0% water level judgment.

Specifically, the water level detecting structure of the present embodiment includes a first probe 1 and a second probe 2, and the vertical height of the first probe 1 is lower than the vertical height of the second probe 2. Still include water heating plate, first probe 1 pastes water heating plate.

The detection principle is as follows: under the condition that no water exists in the heating container, the temperature of the first probe 1 can be increased by heating the water heating plate, at the moment, the temperature of the second probe 2 cannot be increased or is larger than that of the first probe 1 due to the fact that no water exists in the container, and when the temperature difference between the first probe 1 and the second probe 2 reaches a set value, the fact that no water exists in the heating container is judged.

It should be noted that, in this embodiment, the first probe 1 and the second probe 2 should be disposed at the bottom of the container, and satisfy the vertical height difference allowed by the first probe 1 and the second probe 2, and the first probe 1 should be attached to the bottom of the container or disposed below the bottom of the container as much as possible.
