What Fig. 2 and Fig. 3 show are all refrigerator dispensers with lighting devices in the prior art.

In the lighting device of the above-mentioned dispenser, the light source 4' is scattered from one point to the surroundings, which makes the local light of the dispenser too strong. Cause adverse stimulation to human eyes; and the lighting source scatters around, which will affect the lighting and visual effects, which is not conducive to accurate indication and positioning of the position of the dispenser; and the above solutions do not disclose the opening method of the lighting device. Type opening mode will obviously bring inconvenience to the user.

The refrigerator dispenser with lighting device of the utility model comprises a dispenser body 1, a button 2, and a water tray 3, and the dispenser body 1 is provided with a lighting device. Fig. 4 is a schematic diagram of the structure of the lighting device of the present invention. The lighting device includes a lighting source 4 and a lighting source power supply line 5. The directional light diffusion device 6 covers the lighting light source 4 and makes the light emitted by the lighting source 4 directional diffuse; the lighting source power supply line 5 is provided with an inductive power switch 7. An induction probe 8 is connected thereto.

The illumination light source 5 is a lamp tube or a light bulb. The lighting source power line 5 can be connected to the power supply of the refrigerator.

Light directional diffusion device 6 is the cover that covers lamp tube, and its material can be transparent or translucent glass or plastics, and its shape can be different according to the position difference of illumination source and the needs of light diffusion irradiation direction. In the following embodiments, the light orientation and diffusion devices 6 have different shapes, and are respectively marked as 6a, 6b, 6c, 6d, and 6e.

Figures 5 to 9 are schematic diagrams of the states and effects of the lighting device for the dispenser of the present invention when it is located at different positions of the dispenser, where the direction of the arrow indicates the direction of light fading.

FIG. 5 is a state where the lighting source of the dispenser is located at the rear side of the button 2 . At this time, the light directional diffusion device is an arc-shaped strip 6a with an opaque middle and transparent sides, and the middle protrudes outward, as shown in FIG. 5a. It is vertically installed on the rear side of the dispenser button 2 vertically to the water receiving tray 3 and is close to the rear wall of the dispenser body 1 . The illuminating light source 5 is located behind the light directional diffusion device 6a. Therefore, the light penetrates from both sides of the light directional diffusion device 6a, diffuses to both sides along the middle part of the rear wall of the distributor 1, and the light gradually becomes darker from the middle to both sides. Because the middle of the light directional diffusion device 6a is opaque, and the light shines out from its two sides, so the human eye directly looks at the dispenser without dazzling feeling, and can accurately find the positions of the dispenser 1 and the button 2 and get water or water through the button. Take ice.

FIG. 6 is a state where the lighting source of the dispenser is located at the bottom of the water receiving tray 3 . The directional light diffusion device is a semicircular transparent or translucent flat plate 6b matching the shape of the water receiving tray, as shown in FIG. 6a. It is located at the lower part of the water receiving tray 3, and the light source is located at the lower part of the light directional diffusion device 6b. This moment, light diffuses upwards by the water receiving tray 3, and it is darker than the upper light.

FIG. 7 is the state when the dispenser illumination light source is located on the inner periphery of the dispenser body 1 . The light directional diffusion device is a transparent or translucent strip or a rectangular frame 6c composed of the strips embedded in the inner periphery of the distributor body, see Figure 7a. The light source is located at the rear of the light directional diffusion device 6c on each side. At this time, the lighting light diffuses from the sides to the middle, and the light is darker than the middle. Since the button 2 is located in the middle, when taking water or ice through the button 2, even if people look directly at the dispenser button, there will be no dazzling feeling.

Fig. 8 is the state when the illuminating light source of the dispenser is located on the periphery of the rear wall of the dispenser body. The rear wall is in the shape of an arc sunken toward the interior of the refrigerator, and the directional light diffusion device is an arc-shaped plate 6d attached to the rear wall of the dispenser, as shown in Figure 8a. The light source is located on the periphery of the arc-shaped plate-shaped light directional diffusion device. Therefore, the light of the distributor is diffused from all sides to the middle, and the light is darker beyond the middle, so there will be no dazzling feeling when using the distributor.

Fig. 9 The state where the lighting source of the dispenser is located at the periphery of the back side of the water tray. The light directional diffusion device is a semicircular arc shape 6e matching the shape of the rear periphery of the water receiving tray 3, as shown in FIG. 9a. The light source is arranged at the lower part of the light directional diffusion device 6e, so the light is diffused upwards along the bottom of the rear wall of the distributor body 1 from the rear side of the water tray 3, and the light is darker when it goes up.

The lighting settings of the above-mentioned various dispensers make the light diffuse in a specific direction, and each setting mode prevents the user from causing glare when using the dispenser, and can accurately indicate the position of the dispenser body 1 and the button 2 .

The induction switch 7 of the lighting power supply can be an infrared induction switch, and an infrared induction probe 8 is connected to the switch circuit. Approach and turn on the switch, the dispenser lighting power is turned on and illuminated.

The above-mentioned infrared induction switch can adopt LS-2 type infrared induction switch module. LS-2 is a reflective sensor switch module integrating infrared transmitting circuit, receiving circuit and driving circuit, as shown in Figure 10. The pin functions of the module are as follows: V+ is the positive pole of the power supply, 4-6V (DC), the current is 2-4mA, V- is the negative pole of the power supply; J- is the negative pole of the infrared receiving tube; J+ is the positive pole of the infrared receiving tube. F+ is the positive pole of the infrared emission tube; L1 is the monostable output terminal 1, which outputs a high level for 1 second when the circuit senses a signal; L2 is the monostable output terminal 2, which outputs 1 second when the sensing signal disappears High level, R is the access terminal of the current limiting resistor, P and NC are empty pins.

Figure 11 is a block diagram of the internal circuit of the LS-2 module. The LS-2 module itself emits a beam of infrared light. If there is an object within the range of this infrared light that blocks the infrared light and reflects the infrared light back to the module, the receiving end will respond to the signal when the intensity of the reflected infrared light is sufficient. Perform delay, identification and other processing and drive the monostable output terminal L1 to output a high level for 1 second (over V+ value), and then return to zero (V_ value). When the object leaves, no reflected light enters the receiving end, the circuit drives the monostable output terminal L2 to output a high level for 1 second (up to V+ value), and then returns to zero (V_ value).

The infrared induction switch circuit designed according to the above-mentioned principle of the utility model is shown in Fig. 12 . The infrared receiving tube PH302 and the infrared emitting tube PH303 form the infrared sensing probe 8 . When the infrared emitting tube PH303 emits a beam of infrared light, if someone approaches, the infrared beam will be reflected back to the LS-2 module by the human body, and the infrared receiving tube PH302 will receive the infrared light and send the signal to the internal circuit of the LS-2. After processing by the internal circuit, the L1 terminal outputs a high level for 1 second. This level triggers the conduction of the one-way thyristor VT1, and L1 returns to zero after 1 second. Since the one-way thyristor has a memory function, it still maintains the conduction state, the relay J pulls in, and its contact J closes, turning on The power supply of lighting lamp tube 5, lamp lights up. If the person leaves, the infrared light is no longer reflected, L2 outputs a high level for 1 second, and VT2 is turned on, so that VT1 loses the voltage to maintain its conduction and is cut off. After 1 second, VT2 is cut off, and VT1 is always in the off state. The contact J of the relay is released, the power supply of the lighting tube 5 is turned off, and the lamp goes out.

When the daytime or ambient light is bright, the lighting device of the distributor does not need to be turned on, so the above-mentioned switch circuit is also equipped with a photosensitive circuit. The photosensitive circuit has a photosensitive resistor CDS and a transistor Q2 in series with it. The photosensitive circuit is connected in series. The grounding terminal of the resistor R, when the daytime or ambient light is bright, the resistance of the photosensitive resistor CDS in the photosensitive circuit is small, and the triode Q2 cannot be turned on to form a grounding current, so the infrared emitting tube does not work at this time, and the infrared sensing probe cannot detect The light will not turn on if someone is approaching; of course, a manual switch SW1 can be added to force the light to turn on. When the night or the light is dark, the resistance of the photoresistor is large, and the voltage drop on it will lead the triode to the ground, and the infrared emitting tube will work. According to the above working principle, when a person is detected approaching, the lighting circuit will be connected and the light will be on; When the person leaves, the power supply of the lighting tube is disconnected and the light goes out. The photosensitive circuit is provided so that the lighting device will not be mistakenly turned on when the light is bright, and only at night or when the light is dark to a certain extent, the power of the lighting device is turned on to play the role of lighting.

In the circuit, C2 uses a CJ10-400V metal film capacitor, or a polyester capacitor with a withstand voltage of more than 400V, DW is a 6V voltage regulator diode, and J uses a JRF-13F CD/6V contact 220V small relay. VT2 selects 9013 or 3DG12 medium-power silicon crystal triode for use. The value range of the current limiting resistor R is 1Ω-510Ω. The corresponding reflection distance is 4cm to 1m, the smaller the resistance value, the farther the reflection distance is, which can be determined according to actual needs.

The utility model can also adopt other types of inductive switches, such as capacitive inductive switches and voice-activated switches in the prior art.
