A cooking apparatus, a water level detection device for the cooking apparatus, and a water level detection method for the cooking apparatus according to embodiments of the present application are described below with reference to the accompanying drawings.
The embodiment of the present application provides a water level detection device for a cooking apparatus, which is provided with a water tank 2 with a mounting case 1 therein, see fig. 1, and comprises: a detection assembly 3 and a controller 4;
the detection assembly 3 is arranged on the installation shell 1, and light rays emitted by the detection assembly 3 penetrate through the upper surface and the bottom surface of the water tank 2 in the installation shell 1; the controller 4 is connected with the detection component 3 and determines the water quantity in the water tank 2 according to the parameter change value in the light transmission process.
The arrows in fig. 1 indicate the direction of light propagation. The light that detection component 3 launched passes air between the upper surface of installation shell 1 and water tank 2, the upper surface of water tank 2, the inside air of water tank 2, the water in the water tank 2, the lower surface of water tank 2 and the air between the lower surface of water tank 2 and installation shell 1 in proper order. Wherein the air inside the water tank 2 and the water inside the water tank 2 are variables that may vary throughout the process. Because the absorption degree of the water and the air to the light is different, the quantity of the water in the water outlet tank 2 can be judged according to the parameter change value in the light transmission process. In the embodiment of the application, the detection component 3 is arranged on the installation shell 1, and in the water adding process of the water tank 2, the water tank 2 is taken out from the installation shell 1 for water adding, so that the possibility that the detection component 3 is splashed by water is reduced. And the water quantity of the water tank 2 is judged through the parameter variation value of the light penetrating through the water tank 2 in the transmission process, the water tank is clean and sanitary, the water in the water tank 2 cannot be polluted, and the water level detection precision is high.
As shown in fig. 1, the detection assembly 3 includes a light emitting element 31, a light receiving element 32, and an analog-to-digital conversion circuit 33;
the light emitting element 31 and the light receiving element 32 are both disposed on the mounting case 1, and the light emitted from the light emitting element 31 is received by the light receiving element 32 through the upper surface and the bottom surface of the water tank 2;
the analog-to-digital conversion circuit 33 is respectively connected with the light receiving element 32 and the controller 4, determines an energy value corresponding to the light received by the light receiving element 32 in unit time, and transmits the energy value to the controller 4; and the controller 4 is configured to calculate an energy loss value corresponding to the light according to a pre-stored energy initial value and the energy value transmitted by the analog-to-digital conversion circuit 33, and use the energy loss value as a parameter change value. And the controller 4 is used for determining the water amount corresponding to the energy loss value from a preset energy-water level curve according to the energy loss value.
The unit time may be 1 second, 2, second, 3 seconds, or the like. The embodiment of the application does not limit the value of the unit time, and the value of the unit time can be set according to requirements in practical application.
Since the energy of the light is lost during the propagation process, the energy loss degree of the light propagating in water and air is different, the amount of water in the water tank 2 is different, and the energy loss value of the light penetrating through the water tank 2 is also different. In the embodiment of the application, an energy-water level curve is preset in the controller 4, the energy-water level curve is obtained through a large number of tests and fitting, and the energy loss value caused by the fact that light penetrates through the water tank 2 is a change relation curve along with the water quantity in the water tank 2. The embodiment of the present application also presets an initial energy value in the controller 4, where the initial energy value is an energy value when the light emitted by the light emitting element 31 per unit time is not lost.
As for the light received by the light receiving element 32 per unit time to penetrate the water tank 2, the light as an analog quantity is converted into a numerically quantized energy value by the analog-to-digital conversion circuit 33, and the energy value is transmitted to the controller 4. The controller 4 calculates a difference between a preset initial energy value and the energy value transmitted from the analog-to-digital conversion circuit 33, and determines the difference as an energy loss value caused by the light penetrating the water tank 2. The controller 4 locates the water volume corresponding to the energy loss value from a preset energy-water level curve according to the energy loss value, and determines the water volume as the current water volume in the water tank 2. The water quantity in the water tank 2 is judged by determining the energy loss value caused by the fact that light penetrates through the water tank 2 and combining a preset energy-water level curve, the water tank is clean and sanitary, water in the water tank 2 cannot be polluted, and the water level detection precision is high.
As shown in fig. 2, the detection assembly 3 includes a light emitting element 31 and a light receiving element 32;
the light emitting element 31 and the light receiving element 32 are both disposed on the mounting case 1, and the light emitted from the light emitting element 31 is received by the light receiving element 32 through the upper surface and the bottom surface of the water tank 2; the light emitting element 31 and the light receiving element 32 are both connected to the controller 4; a controller 4 for detecting that the light emitting element 31 emits light and starting timing; when the light receiving element 32 detects that light is received, timing is stopped, and the propagation time of the light obtained by timing is used as a parameter change value. And the controller 4 is used for determining the water amount corresponding to the propagation duration from a preset duration-water level curve according to the propagation duration of the light.
Since the amount of water in the water tank 2 varies due to the difference in the propagation speed of light in water and air, the time period required for light to penetrate the water tank 2 also varies. In the embodiment of the application, a time-water level curve is preset in the controller 4, the time-water level curve is obtained through a large number of tests and fits, and the propagation time required by light penetrating through the water tank 2 is a relation curve of the change of the water quantity in the water tank 2. The controller 4 starts timing when the light emitting element 31 emits light. When the light receiving element 32 receives the light, the timing is stopped. The time length obtained by timing is the propagation time length of the light penetrating through the water tank 2, the water quantity corresponding to the propagation time length is positioned from the preset time length-water level curve according to the propagation time length, and the water quantity is determined as the current water quantity in the water tank 2. The water quantity in the water tank 2 is judged by timing the propagation time of the light penetrating through the water tank 2 and combining a preset time-water level curve, so that the water tank is clean and sanitary, the water in the water tank 2 cannot be polluted, and the water level detection precision is high.
In the present embodiment, the line between the emitting end of the light emitting element 31 and the receiving end of the light receiving element 32 passes through the upper surface and the bottom surface of the water tank 2, thereby ensuring that the light emitted from the light emitting element 31 can penetrate the water in the water tank 2. A line between the emitting end of the light emitting element 31 and the receiving end of the light receiving element 32 may be perpendicular to the upper surface and the bottom surface of the water tank 2, so that the light emitted from the light emitting element 31 passes through the water tank 2 vertically from top to bottom. Of course, the line between the emission end of the light emitting element 31 and the reception end of the light receiving element 32 may also be obliquely passed through the upper surface and the bottom surface of the water tank 2. A case where a line between the emission end of the light emitting element 31 and the receiving end of the light receiving element 32 is perpendicular to the upper surface and the bottom surface of the water tank 2 is only schematically shown in fig. 1 and 2.
In the present embodiment, the light emitting element 31 is an infrared emitter, and the light receiving element 32 is an infrared receiver. The light emitted from the light emitting element 31 may be ultraviolet light or any other light having energy, in addition to infrared light.
In this application embodiment, the light that detection component launched passes air, water tank upper surface, the inside air and water of water tank, the air between water tank lower surface and the installation shell between installation shell and the water tank upper surface in proper order. The air and water inside the tank are variables in the overall process. The water quantity in the water tank is judged according to the parameter change value of the light by utilizing the different light absorption degrees of water and air. Further, the parameter variation value is the propagation time required by the light to penetrate through the water tank, and the water quantity in the water tank is determined according to the propagation time and a preset time-water level curve. Or, the parameter change value is an energy loss value caused by the light penetrating through the water tank, and the water quantity in the water tank is determined according to the energy loss value and a preset energy-water level curve. Through the contactless water level detection mode, the water tank is clean and sanitary, water in the water tank cannot be polluted, and the water level detection precision is high.
Referring to fig. 1 or 2, the embodiment of the present application also eliminates a cooking apparatus including the water level detecting device according to the above embodiment. This cooking equipment is for the cooking device who has the steam function, like steam stove, evaporate roast all-in-one, evaporate the all-in-one a little, evaporate roast all-in-one a little or any other equipment that possesses the water tank and have the water level detection demand a little.

detecting that a light emitting element included in the water level detection device emits light, and starting timing; detecting that a light receiving element included in the water level detection device receives light, and stopping timing; and determining the propagation time of the light obtained by timing as a parameter change value.
Because the amount of water in the tank varies due to the different propagation speeds of light in water and air, the length of time required for light to penetrate the tank will also vary. The embodiment of the application is preset with a time-water level curve, the time-water level curve is obtained through a large number of test fitting, and the propagation time required by light penetrating through a water tank is a relation curve changing along with the water quantity in the water tank. The timing is started when the light emitting element included in the water level detecting apparatus emits light. When the light receiving element receives the light, the timing is stopped. The time length obtained by timing is the propagation time length of the light penetrating the water tank.
If the parameter change value is the energy loss value of the light, the energy loss value caused by the light penetrating through the water tank is obtained by the following method, including:
acquiring an energy value corresponding to light received by a light receiving element in unit time, wherein the light receiving element is included in the water level detection device; calculating an energy loss value corresponding to the light according to the energy value and a pre-stored energy initial value; and determining the energy loss value as the parameter change value corresponding to the light.
Because the energy of the light is lost in the transmission process, the energy loss degree of the light transmitted in water and air is different, the water quantity in the water tank is different, and the energy loss value of the light penetrating through the water tank is also different. The embodiment of the application is provided with an energy-water level curve in advance, the energy-water level curve is obtained through a large number of tests and fitting, and the energy loss value caused by light penetrating through the water tank is a relation curve along with the change of the water amount in the water tank. The embodiment of the application also presets an energy initial value, wherein the energy initial value is an energy value when the light emitted by the light emitting element in the water level detection device in unit time is not lost. For the light penetrating through the water tank received by the light receiving element in unit time, the light serving as analog quantity is converted into a numerical quantitative energy value through an analog-to-digital conversion circuit, the difference value between the preset initial energy value and the energy value converted by the analog-to-digital conversion circuit is calculated, and the difference value is determined as the energy loss value caused by the light penetrating through the water tank.
Step 102: and determining the water quantity in the water tank according to the parameter change value.
And if the parameter change value is the propagation time required by the light to penetrate through the water tank, determining the water quantity corresponding to the propagation time from a preset time-water level curve according to the propagation time.
The water quantity in the water tank is judged by timing the propagation time of the light penetrating through the water tank and combining a preset time-water level curve, the water tank is clean and sanitary, the water in the water tank cannot be polluted, and the water level detection precision is high
And if the parameter change value is an energy loss value caused by the fact that the light penetrates through the water tank, determining the water quantity corresponding to the energy loss value from a preset energy-water level curve according to the energy loss value.
The water quantity in the water tank is judged by determining the energy loss value caused by the fact that light rays penetrate through the water tank and combining a preset energy-water level curve, the water tank is clean and sanitary, water in the water tank cannot be polluted, and the water level detection precision is high.
