In this embodiment, the transmitter and the receiver are applied to the inner pan of the cooking appliance, the infrared ray emitted by the transmitter is reflected to the receiver by the material in the inner pan, and therefore the controller can judge the volume of the material in the inner pan. The transmitter and the receiver can be mounted on the side wall of the inner pot, and also can be mounted on the cover body assembly of the inner pot, so that the limitation is not required, and the transmitter and the receiver can detect materials in the inner pot only when the cooking appliance runs. The transmitter and receiver may be adjacent to each other to reduce the size of the light guide block 10, facilitating the light guide block 10 to house both the transmitter and receiver.
The first shading groove 11 and the second shading groove 12 are arranged on the same side wall of the light guide block 10, the first light guide hole 13 and the second light guide hole 14 penetrate through the side wall opposite to the first shading groove 11, and when the light guide device is installed, the first shading groove 11 and the second shading groove 12 are correspondingly covered on the transmitter and the receiver; or, the emitter is firstly installed in the first light-shielding groove 11, the receiver is installed in the second light-shielding groove 12, and then the light guide device is integrally installed in the inner pot or the cover body assembly of the cooking appliance. The first shading groove 11 and the second shading groove 12 can prevent the transmitter and the receiver from being interfered due to light entering from the side surface, so that the accuracy of the transmitter and the receiver on the material detection result is ensured.
The utility model discloses the light guide device is through offering first shading groove 11 and second shading groove 12 on leaded light piece 10 to and first leaded light hole 13 and second leaded light hole 14 with first shading groove 11 and second shading groove 12 intercommunication respectively, thereby when installing light guide device, only need a leaded light piece 10 alright cover simultaneously and establish transmitter and receiver, simplified from this and carried out the process of shading to transmitter and receiver, improved assembly efficiency.
As shown in fig. 2 to 5, a light blocking rib 15 is disposed between the first light blocking groove 11 and the second light blocking groove 12. In the present embodiment, the light blocking rib 15 is disposed on a sidewall where the first light blocking groove 11 and the second light blocking groove 12 are located, and the light blocking rib 15 may protrude from the sidewall to enhance the light blocking effect. The light blocking rib 15 can further prevent infrared rays of the emitter from directly irradiating the receiver, so that the detection accuracy of the material is further improved.
As shown in fig. 2 and fig. 3, the light blocking rib 15 and the light guide block 10 are integrally formed. In the embodiment, the light blocking rib 15 and the light guide block 10 can be integrally injection molded to improve the structural strength of the light blocking rib 15 and reduce the production cost. In another embodiment, as shown in fig. 4 and 5, an insertion groove 16 is formed on the light guide block 10, and the light blocking rib 15 is inserted into the insertion groove 16. The light blocking ribs 15 are detachably embedded in the embedding grooves 16, so that the light blocking ribs 15 with different protruding sizes can be replaced according to the light blocking effect, and the light blocking effect is enhanced.

Taking the first light guide hole 13 as an example, if the included angle between two opposite side edges on the axial cross section of the first light guide hole 13 is less than 10 °, the infrared ray is not favorably diffused; if the angle is more than 20 degrees, the volume of the light guide hole is increased, so that the occupied space of the light guide block 10 is increased; therefore, the included angle is set to be 10-20 degrees, and can be selected to be 15 degrees, so that the infrared diffusion of the emitter can be ensured, and the occupied space of the light guide block 10 can be reasonably controlled. The effect of the included angle between the two opposite sides on the axial cross section of the second light guide hole 14 corresponds to that of the first light guide hole 13, and is not described herein again.
The light guide block 10 is made of light blocking material. In this embodiment, the light guide block 10 can be made of silica gel, which has excellent light-shielding effect, low cost and easy material availability; meanwhile, the infrared transmitting terminal has certain elasticity, and is not easy to damage due to the fact that the infrared transmitting terminal or the infrared receiving terminal is touched. Specifically, the light guide block 10 is made of a black material to further improve the light shielding effect.
The hole wall of the first light guide hole 13 and/or the second light guide hole 14 is provided with an electroplated layer. The electroplated layer accessible electroplating process forms, and the electroplated layer can make the pore wall of first leaded light hole 13 and second leaded light hole 14 brighter to can improve the reflection effect to infrared ray, make along infrared ray can all shine to interior pot along first leaded light hole 13, or shine to the receiver along second leaded light hole 14, avoid the pore wall absorption infrared ray of light guide block 10, thereby improve detection efficiency.
