Description

Steam cooking utensil

Technical Field

The utility model belongs to the technical field of kitchen utensil, especially, relate to a steam cooking utensil.

Background

Steam cooking appliances, such as steam cookers, are generally provided with a water tank for supplying liquid into a steam generator, so that the liquid is heated in the steam generator to be vaporized into steam, and then enters a cooking cavity to heat food. In order to monitor the amount of liquid in the water tank, a water level monitoring device is generally provided in the water tank.

The existing water level monitoring device consists of a reed switch and a float ball, wherein the reed switch is positioned at the upper part of a water tank, a magnet is arranged in the float ball, the float ball floats up and down along with the liquid level in the water tank, when the float ball and the magnet in the float ball enter the induction range of the reed switch, the reed switch is conducted, and a power panel receives a switching signal to judge that the liquid level of the water tank is sufficient at the moment; when the liquid level descends or the liquid level of the water tank is insufficient, the floater ball is far away from the reed pipe, the circuit of the reed pipe is disconnected, the power panel receives a disconnection signal, and the liquid level is judged to be insufficient.

The structure for detecting the liquid level of the water tank by means of the reed pipe and the floater ball can only detect the highest point and the lowest point of the liquid level. When the reed switch is positioned at the highest point of the liquid level of the water tank, a user must add the liquid level of the water tank to the highest point before working every time, otherwise, the float ball and the reed switch cannot be conducted, and software judges that the liquid level is insufficient at the moment, the work cannot be started, more time is occupied for the user, and resources are wasted; when the reed switch is located the water tank liquid level minimum, as long as the liquid level is higher than the minimum that sets up before work at every turn, the machine can all begin to work, but if the liquid in the culinary art in-process water tank has consumed, the lack of water trouble can be reported to the machine, if the user does not in time supply liquid, the machine just is in the fault state all the time, can't continue normal work. And, the cost of the assembly of the reed switch and the float ball is high.

In addition, by utilizing the detection mode of the reed pipe and the float ball, whether liquid exists in the water tank or not can not be fed back in real time, if the liquid in the water tank is consumed up in advance, the detection cannot be carried out, and at the moment, the steam generator can be dried because no liquid enters the steam generator.
