Abstract
Description
Technical Field
[0001] This utility model relates to the field of ice maker technology, specifically to an ice full detection device and an ice making system. Background Technology
[0002] Once the ice maker starts making ice, it continues to do so. The ice cubes detach under the influence of gravity and the mechanical structure, falling into an ice box to collect them, ensuring the ice-making components can continue producing ice. However, in related technologies, the ice-making speed is affected by various factors, and the ice cubes falling into the ice box are irregularly stacked, making it uncertain when the box will fill. This makes it difficult to accurately determine if the box is full, or if the user removes a small amount of ice, the ice may become uneven, making it impossible to determine if more ice can be made. Continuing to make ice when the box is full can cause ice to rise above the ice box support, jamming the box and preventing it from being easily pulled out. Utility Model Content
[0003] In view of this, the present invention provides an ice fullness detection device and an ice-making system to solve the problem that related technologies cannot accurately detect whether the ice is full.
[0004] Firstly, this utility model provides an ice fullness detection device, comprising:
[0005] A light emitting module, wherein the light emitting module is adapted to emit light;
[0006] A light receiving module is adapted to receive light, and the light emitting module and the light receiving module are located at positions corresponding to the height of the ice blocks when the ice box is full.
[0007] The refraction module is capable of receiving and refracting light. The light emitting module, the refraction module, and the light receiving module form a light transmission path, which penetrates the ice box horizontally at at least two locations.
[0008] Beneficial effects: By incorporating a refraction module, which receives and refracts light, the light emitting module, refraction module, and light receiving module form a light transmission path. This path penetrates the ice box horizontally at at least two locations. Therefore, when the ice box is full, the ice blocks are positioned along the light transmission path, and the light receiving module receives little or no light, allowing for accurate detection of fullness. Furthermore, the fact that the light transmission path penetrates the ice box horizontally at at least two locations avoids the problem of inaccurate fullness detection caused by uneven ice distribution within the ice box.
[0009] In one optional implementation, the refraction module includes a first refraction module and a second refraction module, wherein the first refraction module and the light emitting module are facing each other, and the second refraction module and the light receiving module are facing each other.
[0010] Beneficial effects: The refraction module includes a first refraction module and a second refraction module. The first refraction module is directly opposite the light emitting module, and the second refraction module is directly opposite the light receiving module. Therefore, the first refraction module receives and refracts the light emitted by the light emitting module, the second refraction module receives and refracts the light refracted by the first refraction module, and the light receiving module receives the light refracted by the second refraction module. This ensures that the light transmission path passes through the ice box horizontally at least at two locations, avoiding the problem of inaccurate detection of ice fullness due to uneven distribution of ice blocks in the ice box.
[0011] In one optional embodiment, the light emitting module and the light receiving module are located on the same side of the ice box, and the first refraction module and the second refraction module are located on the same side of the ice box.
[0012] Beneficial effects: The light emitting module and the light receiving module are located on the same side of the ice box, as are the first refraction module and the second refraction module. The first refraction module and the light emitting module face each other, and the second refraction module and the light receiving module face each other. The first refraction module receives and refracts the light emitted by the light emitting module, the second refraction module receives and refracts the light refracted by the first refraction module, and the light receiving module receives the light refracted by the second refraction module. The light transmission path runs horizontally through the ice box at both locations, avoiding the problem of inaccurate ice fullness detection caused by uneven distribution of ice blocks inside the ice box. By placing the first and second refraction modules on the same side of the ice box, their structural shapes are also relatively simple, facilitating the transmission of light along a predetermined path.
[0013] In one alternative embodiment, the first refraction module includes a first surface, a second surface, and a third surface connecting the first surface and the second surface. The first surface is directly opposite the light emitting module and perpendicular to the light emitted by the light emitting module, and the second surface is perpendicular to the first surface.
[0014] Beneficial effects: The first surface is directly opposite the light emitting module and perpendicular to the light emitted by the light emitting module. The second surface is perpendicular to the first surface. Therefore, the light emitted by the light emitting module can pass vertically through the first surface, be reflected by the third surface, and then pass horizontally through the second surface.
[0015] In one alternative embodiment, the second refractive module includes a fourth surface, a fifth surface, and a sixth surface connecting the fourth surface and the fifth surface, wherein the fourth surface is parallel to and directly opposite the second surface, and the fifth surface is perpendicular to the fourth surface and directly opposite the light receiving module.
[0016] Beneficial effect: The fourth surface is parallel to and directly opposite the second surface, and the fifth surface is perpendicular to the fourth surface and directly opposite the light receiving module. Therefore, light that passes horizontally through the second surface can pass horizontally through the fourth surface, and after being reflected by the sixth surface, it passes vertically through the fifth surface.
[0017] In one optional embodiment, the refraction module further includes a third refraction module, which is capable of receiving light refracted by the first refraction module and transmitting the light to the second refraction module. The third refraction module and the first refraction module are located on different sides of the ice box.
[0018] Beneficial effects: The third refraction module can receive the light refracted by the first refraction module and transmit the light to the second refraction module. The third refraction module and the first refraction module are located on different sides of the ice box, so four rays of light will pass through the ice box in the horizontal direction, which can further accurately detect whether the ice box is full.
[0019] In one optional embodiment, the first refraction module includes a first surface, a second surface, and a third surface connecting the first surface and the second surface. The first surface is directly opposite the light emitting module and perpendicular to the light emitted by the light emitting module. The angle between the second surface and the first surface is an obtuse angle.
[0020] Beneficial effects: The first surface is directly opposite the light emitting module and perpendicular to the light emitted by the light emitting module. The angle between the second surface and the first surface is an obtuse angle. Therefore, the angle between the light refracted by the second surface and the light passing through the first surface is an acute angle, which can ensure that the light refracted by the first refraction module can be transmitted to the third refraction module.
[0021] In one optional embodiment, the second refractive module includes a fourth surface, a fifth surface, and a sixth surface connecting the fourth surface and the fifth surface, the fifth surface being directly opposite the light receiving module, and the angle between the fourth surface and the fifth surface being an obtuse angle.
[0022] The third refractive module includes a seventh surface, an eighth surface, and a ninth surface connecting the seventh surface and the eighth surface. The seventh surface is parallel to the second surface, and the eighth surface is parallel to the fourth surface and perpendicular to the seventh surface.
[0023] Beneficial effects: The seventh surface is parallel to the second surface. The light refracted from the first refraction module passes through the seventh surface, is reflected by the ninth surface, and then exits through the eighth surface. Since the fourth surface is parallel to the eighth surface, the light can pass through the fourth surface, be reflected by the sixth surface, and then exit through the fifth surface, heading towards the light receiving module. The entire light transmission path is W-shaped, which can ensure that four light rays pass through the ice box in the horizontal direction, which can further accurately detect whether the ice box is full.
[0024] Secondly, this utility model also provides an ice-making system, comprising:
[0025] Ice box and the aforementioned ice full detection device.
[0026] Beneficial effects: By incorporating a refraction module, which receives and refracts light, the light emitting module, refraction module, and light receiving module form a light transmission path. This path penetrates the ice box horizontally at at least two locations. Therefore, when the ice box is full, the ice blocks are positioned along the light transmission path, and the light receiving module receives little or no light, allowing for accurate detection of fullness. Furthermore, the fact that the light transmission path penetrates the ice box horizontally at at least two locations avoids the problem of inaccurate fullness detection caused by uneven ice distribution within the ice box.
[0027] In one optional embodiment, the ice-making system further includes an inner liner and an ice box support, the ice box support being disposed in the inner liner, the ice box being disposed in the ice box support, the ice full detection device being disposed in the inner liner, and the ice box support and the ice box being provided with through holes for the light transmission path to pass through.
[0028] Beneficial effects: By placing the ice fullness detection device inside the liner, it is convenient to connect the light emitting module and the light receiving module. The ice fullness detection device will not move with the ice box, and the detection results are more reliable. By providing through holes in the ice box bracket and ice box for the light transmission path to pass through, it can be ensured that the light can enter the interior of the ice box.

[0043] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0044] Once the ice maker starts making ice, it continues to do so. The ice cubes detach under the influence of gravity and the mechanical structure, falling into an ice box to collect them, ensuring the ice-making components can continue producing ice. However, in related technologies, the ice-making speed is affected by various factors, and the ice cubes falling into the ice box are irregularly stacked, making it uncertain when the box will fill. This makes it difficult to accurately determine if the box is full, or if the user removes a small amount of ice, the ice may become uneven, making it impossible to determine if more ice can be made. Continuing to make ice when the box is full can cause ice to rise above the ice box support, jamming the box and preventing it from being easily pulled out.
[0045] The related technology discloses an ice full detection component resistant to sunlight interference, including: an infrared emitting circuit and an infrared receiving circuit. The infrared emitting circuit is connected to the I / O output port of a microcontroller to control the infrared emitting head to emit infrared signals and pulse signals; the infrared receiving circuit is connected to the I / O input port of the microcontroller; when the infrared receiving circuit receives an infrared signal, the infrared receiving head is turned on and at a low level; when the infrared receiving circuit does not receive an infrared signal, the infrared receiving head is not turned on and at a high level; the low-level infrared signal received by the infrared receiving circuit is used to judge the level difference and the interference from opening the cover.
[0046] In the aforementioned technologies, the infrared transmitter and receiver are positioned opposite each other, and the light emitted by the infrared transmitter is directly received by the infrared receiver. This may result in some ice blocks being piled up to a higher height in the ice box, while others are piled up to a lower height, thus making it impossible to accurately detect whether the ice box is full.
[0047] The following is combined Figures 1 to 8 The following describes embodiments of the present invention.
[0048] According to an embodiment of the present invention, an ice fullness detection device is provided, comprising: a light emitting module 1, a light receiving module 2, and a refraction module.
[0049] Among them, the light emitting module 1 is suitable for emitting light; the light receiving module 2 is suitable for receiving light, and the light emitting module 1 and the light receiving module 2 are located at positions corresponding to the height of the ice block when the ice box 6 is full; the refraction module can receive and refract light, and the light emitting module 1, the refraction module, and the light receiving module 2 form a light transmission path, which passes through the ice box 6 horizontally at least two positions.
[0050] In this embodiment, a refraction module is provided, which can receive and refract light. The light emitting module 1, the refraction module, and the light receiving module 2 form a light transmission path. The light transmission path passes through the ice box 6 horizontally at at least two locations. Therefore, when the ice box is full, the ice blocks are located on the light transmission path, and the light receiving module 2 cannot receive light or receives very weak light, thus accurately detecting whether the ice box is full. Since the light transmission path passes through the ice box 6 horizontally at at least two locations, the problem of inaccurate detection of fullness due to uneven distribution of ice blocks within the ice box 6 can be avoided.
[0051] In one specific embodiment, the light emitting module 1 can emit infrared rays, and the light receiving module 2 can receive infrared rays.
[0052] In one embodiment, such as Figure 2 As shown, the refraction module includes a first refraction module 3 and a second refraction module 4. The first refraction module 3 and the light emitting module 1 are directly opposite each other, and the second refraction module 4 and the light receiving module 2 are directly opposite each other.
[0053] In this embodiment, the refraction module includes a first refraction module 3 and a second refraction module 4. The first refraction module 3 and the light emitting module 1 are directly opposite each other, and the second refraction module 4 and the light receiving module 2 are directly opposite each other. Therefore, the first refraction module 3 receives and refracts the light emitted by the light emitting module 1, the second refraction module 4 receives and refracts the light refracted by the first refraction module 3, and the light receiving module 2 receives the light refracted by the second refraction module 4. This ensures that the light transmission path passes through the ice box 6 horizontally at least at two locations, which can avoid the problem of inaccurate detection of ice fullness due to uneven distribution of ice blocks in the ice box 6.
[0054] In one embodiment not shown in the figure, only one refraction module is provided. The light emitting module 1 and the light receiving module 2 are located on the same side of the ice box 6, and the refraction module is located on the other side of the ice box 6, on the center vertical line connecting the light emitting module 1 and the light receiving module 2. The refraction module receives and refracts the light emitted by the light emitting module 1, and the light receiving module 2 receives the light refracted by the refraction module. This also ensures that the light transmission path passes through the ice box 6 horizontally at both positions, which can avoid the problem of inaccurate detection of ice fullness due to uneven distribution of ice in the ice box 6.
[0055] In one embodiment, the light emitting module 1 and the light receiving module 2 are located on the same side of the ice box 6, and the first refraction module 3 and the second refraction module 4 are located on the same side of the ice box 6.
[0056] In this embodiment, the light emitting module 1 and the light receiving module 2 are located on the same side of the ice box 6, and the first refraction module 3 and the second refraction module 4 are also located on the same side of the ice box 6. The first refraction module 3 and the light emitting module 1 face each other, and the second refraction module 4 and the light receiving module 2 face each other. The first refraction module 3 receives and refracts the light emitted by the light emitting module 1, and the second refraction module 4 receives and refracts the light refracted by the first refraction module 3. The light receiving module 2 receives the light refracted by the second refraction module 4. The light transmission path passes through the ice box 6 horizontally at both locations, which avoids the problem of inaccurate detection of ice fullness due to uneven distribution of ice blocks inside the ice box 6. By placing the first refraction module 3 and the second refraction module 4 on the same side of the ice box 6, the structural shapes of the first refraction module 3 and the second refraction module 4 are also relatively simple, facilitating the transmission of light along a predetermined path.
[0057] In one embodiment not shown in the figure, the light emitting module 1 and the light receiving module 2 can be located on different sides of the ice box 6, and the first refraction module 3 and the second refraction module 4 can be located on different sides of the ice box 6.
[0058] In one embodiment, the first refraction module 3 includes a first surface 301, a second surface 302, and a third surface 303 connecting the first surface 301 and the second surface 302. The first surface 301 is directly opposite to the light emitting module 1 and is perpendicular to the light emitted by the light emitting module 1. The second surface 302 is perpendicular to the first surface 301.
[0059] In this embodiment, the first surface 301 is directly opposite to the light emitting module 1 and is perpendicular to the light emitted by the light emitting module 1. The second surface 302 is perpendicular to the first surface 301. Therefore, the light emitted by the light emitting module 1 can pass vertically through the first surface 301, and after being reflected by the third surface 303, pass horizontally through the second surface 302.
[0060] Specifically, such as Figure 3 As shown, on the cross-section of the first refractive module 3, the first surface 301, the second surface 302, and the third surface 303 form an isosceles right triangle.
[0061] In one embodiment, the second refraction module 4 includes a fourth surface 401, a fifth surface 402, and a sixth surface 403 connecting the fourth surface 401 and the fifth surface 402. The fourth surface 401 is parallel to and directly opposite the second surface 302, and the fifth surface 402 is perpendicular to the fourth surface 401 and directly opposite the light receiving module 2.
[0062] In this embodiment, the fourth surface 401 is parallel to and directly opposite the second surface 302, and the fifth surface 402 is perpendicular to the fourth surface 401 and directly opposite the light receiving module 2. Therefore, light that passes horizontally through the second surface 302 can pass horizontally through the fourth surface 401, and after being reflected by the sixth surface 403, pass vertically through the fifth surface 402.
[0063] Specifically, such as Figure 4 As shown, on the cross-section of the second refractive module 4, the fourth surface 401, the fifth surface 402, and the sixth surface 403 form an isosceles right triangle.
[0064] In one embodiment, such as Figure 5 As shown, the refraction module also includes a third refraction module 5, which can receive the light refracted by the first refraction module 3 and transmit the light to the second refraction module 4. The third refraction module 5 and the first refraction module 3 are located on different sides of the ice box 6.
[0065] In this embodiment, the third refraction module 5 can receive the light refracted by the first refraction module 3 and transmit the light to the second refraction module 4. The third refraction module 5 and the first refraction module 3 are located on different sides of the ice box 6, so four rays of light will pass through the ice box 6 in the horizontal direction, which can further accurately detect whether it is full of ice.
[0066] Specifically, such as Figure 5 As shown, the first refraction module 3 is directly opposite the light emitting module 1, receiving and refracting the light emitted by the light emitting module 1. The third refraction module 5 receives the light refracted by the first refraction module 3 and transmits the light to the second refraction module 4. The second refraction module 4 receives the light from the third refraction module 5 and transmits it to the light receiving module 2. The light transmitted from the light emitting module 1 to the first refraction module 3 is the first ray. The light refracted by the first refraction module 3 is the second ray. The light refracted by the third refraction module 5 is the third ray. The light refracted by the second refraction module 4 is the fourth ray. The first ray, the second ray, the third ray, and the fourth ray all pass through the ice box 6 in the horizontal direction, which can further accurately detect whether it is full of ice.
[0067] In one embodiment, the first refraction module 3 includes a first surface 301, a second surface 302, and a third surface 303 connecting the first surface 301 and the second surface 302. The first surface 301 is directly opposite to the light emitting module 1 and is perpendicular to the light emitted by the light emitting module 1. The angle between the second surface 302 and the first surface 301 is an obtuse angle.
[0068] In this embodiment, the first surface 301 and the light emitting module 1 are directly opposite each other and perpendicular to the light emitted by the light emitting module 1. The angle between the second surface 302 and the first surface 301 is an obtuse angle. Therefore, the angle between the light refracted by the second surface 302 and the light passing through the first surface 301 is an acute angle, which can ensure that the light refracted by the first refraction module 3 can be transmitted to the third refraction module 5.
[0069] In one embodiment, the second refraction module 4 includes a fourth surface 401, a fifth surface 402, and a sixth surface 403 connecting the fourth surface 401 and the fifth surface 402. The fifth surface 402 is directly opposite the light receiving module 2, and the angle between the fourth surface 401 and the fifth surface 402 is an obtuse angle. The third refraction module 5 includes a seventh surface 501, an eighth surface 502, and a ninth surface 503 connecting the seventh surface 501 and the eighth surface 502. The seventh surface 501 is parallel to the second surface 302, and the eighth surface 502 is parallel to the fourth surface 401 and perpendicular to the seventh surface 501.
[0070] In this embodiment, the seventh surface 501 is parallel to the second surface 302. The light refracted from the first refraction module 3 passes through the seventh surface 501, is reflected by the ninth surface 503, and then exits through the eighth surface 502. Since the fourth surface 401 is parallel to the eighth surface 502, the light can pass through the fourth surface 401, be reflected by the sixth surface 403, and then exit through the fifth surface 402, and then be directed towards the light receiving module 2. The entire light transmission path is W-shaped, which can ensure that four light rays pass through the ice box 6 in the horizontal direction, and can further accurately detect whether it is full of ice.
[0071] It should be noted that, Figure 2 and Figure 5 The path formed by straight lines with arrows represents the path of light transmission.
[0072] According to an embodiment of the present invention, another aspect provides an ice-making system, including: an ice box 6 and the ice full detection device provided in the above embodiment.
[0073] In this embodiment, a refraction module is provided, which can receive and refract light. The light emitting module 1, the refraction module, and the light receiving module 2 form a light transmission path. The light transmission path passes through the ice box 6 horizontally at at least two locations. Therefore, when the ice box is full, the ice blocks are located on the light transmission path, and the light receiving module 2 cannot receive light or receives very weak light, thus accurately detecting whether the ice box is full. Since the light transmission path passes through the ice box 6 horizontally at at least two locations, the problem of inaccurate detection of fullness due to uneven distribution of ice blocks within the ice box 6 can be avoided.
[0074] In one embodiment, the ice-making system further includes an inner liner 8 and an ice box support 7. The ice box support 7 is disposed in the inner liner 8, the ice box 6 is disposed in the ice box support 7, the ice full detection device is disposed in the inner liner 8, and the ice box support 7 and the ice box 6 are provided with through holes for the light transmission path to pass through.
[0075] In this embodiment, by placing the ice full detection device in the inner liner 8, it is convenient to connect the light emitting module 1 and the light receiving module 2. The ice full detection device will not move with the ice box 6, and the detection result is more reliable. By providing through holes for the light transmission path in the ice box bracket 7 and the ice box 6, it can be ensured that the light can enter the interior of the ice box 6.
[0076] In one specific embodiment, the ice-making system includes an ice mold evaporator for making ice blocks. The ice box 6 is connected to a handle assembly 10. After one round of ice making is completed, the ice blocks will fall into the ice box 6 below due to gravity. The process of the ice blocks falling will obstruct the light transmission path, causing the light receiving module 2 to be unable to receive light or to receive very weak light. It can be determined that the ice removal is completed and the next round of ice making can begin. When the ice blocks in the ice box 6 are nearly full, after the last ice removal, the light transmission will be blocked for a long time, making the light receiving module 2 unable to effectively receive light. At this time, it can be determined that the ice blocks in the ice box 6 are full and ice making should be stopped to ensure that the user can easily pull out the ice box 6 when taking out ice. When the user takes out some ice, if the light receiving module 2 still cannot effectively receive light, it means that the ice blocks in the ice box 6 are unevenly distributed and the ice blocks are too high in some places. At this time, ice making cannot continue. If the light receiving module 2 can receive light, ice making can continue.
[0077] Specifically, the refraction module is also installed in the inner liner, and the ice box and ice box bracket have through holes corresponding to the refraction module.
[0078] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by this application.
