Embodiment 1

[0028] Embodiment 1 of the present invention provides a method for controlling the discharge of residual water in a water tank, such as figure 1 As shown, the method includes the following steps:

[0029] Step 1, start the drainage program;

[0030] Step 2, obtaining the height of the current water level; specifically: detecting the height of the current water level through a capacitive sensor arranged outside the water tank;

[0031] Step 3, calculate the theoretical time required to empty the remaining water in the water tank according to the height and the drainage flow of the water tank drain valve; specifically: calculate the volume of the remaining water according to the height of the water level, and the quotient of the volume and the drainage flow is the emptying The theoretical time required for the tank;

[0032] Step 4, open the drain valve to start draining water;

[0033] Step 5, obtaining the change of the water level height in real time within the theoretical...

Embodiment 2

[0037] Embodiment 2 of the present invention provides a water tank assembly, such as figure 2 As shown, it includes a water tank body 1, a water level detection unit 2, a drainage unit 3 and a controller. The water level detection unit 2 is arranged on the outside of the water tank body 1 for detecting the water level in the water tank body 1. The drainage unit 3 It is arranged under the water tank body 1 to discharge the remaining water in the water tank body 1, and the controller is connected with the water level detection unit 2;

[0038] Like this, adopt above-mentioned structure, water level detection unit 2 detects the water level height in the water tank body 1, and water level height is transmitted to controller, and controller calculates the emptying margin according to the water level height, the flow velocity of drainage unit 3 and the size of water tank body 1. The time required for water; after that, the drainage unit 3 works, and in this process, the water level...

Embodiment 3

[0048] Embodiment 3 of the present invention provides a steam cooking device, which includes the water tank assembly of Embodiment 2 and a steam cooking device body, and the water tank component is inside the steam cooking device body.

[0049]In addition, the steam cooking device in this embodiment may be a steam box, a steam oven, an integrated steam-oven machine, a steam-oven micro-integrated machine, and the like.

Abstract

The invention discloses a water tank residual water discharge control method, which specifically comprises the following steps: starting a water discharge program, acquiring the height of the currentwater level through a water level detection unit, and calculating the theoretical time required for emptying a water tank according to the height and the water discharge flow of a water tank water discharge valve; opening a drainage valve to start drainage, acquiring the change of the water level height in real time within the theoretical time, if no change is generated at the current time by comparing with the previous water level, giving an abnormal drainage alarm to the water tank, and otherwise, continuing to drain until the theoretical time is ended. The invention further discloses a water tank assembly and a steam cooking device applying the water tank assembly. Through the water level detection unit, the problems that in the prior art, drainage faults cannot be found in time, and potential food safety hazards are caused by excessive residual water in the water tank are solved.

Description

technical field [0001] The invention belongs to the technical field of steam cooking equipment, and in particular relates to a water tank residual water discharge control method, a water tank assembly and a steam cooking device. Background technique [0002] The detection of the remaining water in the existing water tank mostly adopts the magnetic levitation liquid level sensor in the water tank, but the magnetic levitation liquid level sensor can only indicate that the water tank is full of water or lack of water, and the magnetic levitation liquid level sensor needs a certain amount of water to float, and the alarm water level is biased. High, resulting in a lot of residual water, there are food safety hazards such as bacterial growth and odor; moreover, when there are foreign objects in the water pump, electromagnetic switch valve or drainage pipeline, or even the water pump or electromagnetic switch valve is damaged, drainage will occur The problem of slow or even non-dr...
