Problems solved by technology

The induction control device of the water tank adopts the structure of the reed switch and the water level float to realize the judgment of the fixed water level. The use of it will affect the continuity of the cooking process and affect the user experience
In addition, due to the limited volume of the water tank of the steamer, if multiple reed switches are installed in the water tank, there will be a hidden danger of magnetic interference and misjudgment.

Embodiment 1

[0035] Such as figure 1 with figure 2 As shown, the steam box in this embodiment includes a base body, a water tank 1 and a water level detection device arranged in conjunction with the water tank 1. The base body has a bracket 7 for installing the water tank 1, and the water tank 1 can be detachably installed in the bracket 7. For ease of use, The water tank 1 is installed on the bracket 7 in a push-pull manner.

[0036] The water level detection device includes a magnetic buoy 2, a reed switch 3, a driving mechanism 4, and a control circuit board, wherein the reed switch 3 and the driving mechanism 4 are respectively electrically connected to the control circuit board. Wherein the magnetic buoy 2 is arranged in the water tank 1, and the magnetic buoy 2 can float on the water surface and move up and down as the water level of the water surface changes. In order to enable the magnetic buoy 2 to work conveniently with the reed switch 3, a guide 6 is provided on the inner sid...

Embodiment 2

[0044] Such as image 3 As shown, the difference between this embodiment and Embodiment 1 is that a magnet 5 is also arranged in the cavity of the limiting member, and the magnet 5 is fixedly arranged near the bottom of the water tank 1. In this embodiment, the initial state of the reed switch 3 The set position is also set at the position close to the bottom of the water tank 1 , so that the magnet 5 is set corresponding to the initial set position of the reed switch 3 .

[0045] Such as Figure 5 As shown, after the cooking in the steam box is finished, the driving mechanism 4 drives the reed switch 3 to move to the initial set position. When cooking is required, when the water tank 1 is installed in the bracket 7, after the water tank 1 is placed, the control circuit board detects whether the reed switch 3 is engaged by the magnet 5 fixedly arranged at the set position, and if so, it is judged that the water tank is 1 is placed in place; otherwise, it is judged that it is...

Abstract

The invention relates to a water level detection device of a water tank, comprising a magnetic buoy, a reed switch, a driving mechanism, and a control circuit board, the reed switch and the driving mechanism are respectively electrically connected to the control circuit board, and the reed switch is connected to the driving end of the driving mechanism And move up and down corresponding to the moving path of the magnetic buoy. The water level detecting device of the water tank can acquire the water level data at any height in the water tank. The invention relates to a steam box, which includes a base body, a water tank and a water level detection device. The base body has a bracket, the water tank is detachably installed in the bracket, and a driving mechanism and a reed switch are arranged close to the bracket. The steamer can give an early warning to the usage time of the water in the water tank. The invention also relates to a control method of the steamer. After the driving mechanism drives the reed switch to move from the set position to the initial water level position, and after detecting the pull-on signal of the reed switch, the initial water level data in the water tank is calculated. This method can obtain any initial water level data in the water tank under the condition of setting only one dry reed switch.

Description

technical field [0001] The invention relates to a steam box, and also relates to a control method of the steam box. Background technique [0002] When the water tank is used in various electrical appliances, a corresponding water level detection device is usually installed to detect the water level in the water tank. Especially for products with small water tanks such as steamers, the accurate judgment of the water level directly affects other products. Continuity of work. The parameters that usually affect the use of the water tank are the set maximum water level and minimum water level. In the prior art, a magnetic buoy is usually used in conjunction with a reed switch, and the reed switch is set at the highest water level and the minimum water level. , Whether the water in the water tank has reached the position set by the reed switch is judged by whether the reed switch is pulled in or not. This structure can only judge the fixed water level, and cannot predict the work...
