Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, specifically to a water dispensing device. Background Technology

[0002] Water dispensing devices on the market include countertop water purifiers, water dispensers, and other heated drinking water products. To make the water dispensing process more convenient for users, some water dispensing devices are equipped with a cup height measuring device, which controls the water dispensing volume based on the cup height measured by the device.

[0003] Typically, multiple light wave emitters are vertically spaced along one side of a water glass, while the same number of light wave receivers are placed on the other side. Each emitter and receiver corresponds to a specific emitter. The emitters emit light waves, some of which are blocked by the water glass, preventing some receivers from receiving them. The height of the water glass is calculated based on the information from the receivers that did not receive light waves.

[0004] However, the accuracy of measuring the height of the cup in this way is poor. Utility Model Content

[0005] To at least partially address the problems existing in the prior art, according to one aspect of the present invention, a water dispensing device is provided. The water dispensing device includes a main body and a water dispensing component disposed on the main body. The main body has a container placement area corresponding to the water dispensing component. On opposite sides of the container placement area are respectively disposed a transmitter for transmitting measurement signals and a receiver for receiving measurement signals. There are at least two transmitters spaced apart along a predetermined direction from the water dispensing component to the container placement area. The number of receivers is greater than the number of transmitters and the multiple receivers are spaced apart along the predetermined direction. Each receiver is also electrically connected to a signal processing module.

[0006] The water dispensing device provided in this application transmits a measurement signal through each transmitter, and the transmitter, the upper edge of the container, and the corresponding receiver form a line. By using at least two transmitters arranged along a predetermined direction, at least two lines can be obtained. Using at least two lines allows for more accurate measurement of the container's height, and at a lower cost.

[0007] For example, the main body includes a first column, a second column, and an upper crossbeam connecting the first and second columns. The length directions of both the first and second columns are the same as a predetermined direction, and the first and second columns are arranged opposite to each other. The transmitter is disposed on the first column, the receiver is disposed on the second column, and the water outlet is disposed on the upper crossbeam. A container placement area is formed between the first column, the second column, and the upper crossbeam. This arrangement of the first column, the second column, and the upper crossbeam better ensures the installation of the transmitter, the receiver, and the water outlet. The container is placed within the container placement area, and the space between the first column, the second column, and the upper crossbeam forms the container placement area, which better accommodates the container and ensures accurate measurement of its height.

[0008] For example, the main body also includes a placement platform, which is disposed opposite to the water outlet at both ends of the container placement area. A first distance L1 exists between the placement platform and the water outlet, and a second distance L2 exists between the first column and the second column. Each emitter faces the second column and has an included angle α for its emission range. The number of emitters is N. This setup ensures that the total transmission range of multiple transmitters is large enough to better cover multiple receivers and guarantee the accuracy of measurement data.

[0009] For example, each receiver has a receiving range of length L3 in a predetermined direction, and the number of receivers is M. This configuration ensures that the total receiving range of multiple receivers is large enough to better receive measurement signals and guarantee the accuracy of the measurement data. Furthermore, it avoids interference between the multiple receivers.

[0010] For example, each transmitter is provided with a first reflector and a second reflector in a predetermined direction. The first reflector is closer to the upper crossbeam relative to the transmitter, and there is a first included angle β1 between the first reflector and the first column, where 90°≥β1≥67.5°. This arrangement of the first reflector can prevent the intensity of the measurement signal emitted by the transmitter from decreasing, avoid diffuse reflection, and thus prevent the receiver from failing to receive the measurement signal or misreceiving the measurement signal, ensuring the accuracy of the measurement.

[0011] For example, the second reflector is further away from the upper crossbeam relative to the transmitter, and there is a second included angle β2 between the second reflector and the second column, where 90°≥β2≥67.5°. This arrangement of the second reflector prevents a reduction in the intensity of the measurement signal emitted by the transmitter, avoids diffuse reflection, and thus prevents the receiver from failing to receive the measurement signal or misreceiving the measurement signal, ensuring measurement accuracy.

[0012] For example, the second column includes a first part, a second part, and an intermediate part located between the first part and the second part. The first part is located at the end of the second column near the water outlet, and the second part is located at the end of the container placement area away from the water outlet. Multiple receivers are disposed in the intermediate part. The first part has a first part length H1, the second part has a second part length H2, and the intermediate part has a third part length H3. The receiving range of each receiver has a length L3 in a predetermined direction, and the number of receivers is M. By placing the receivers in the middle section, the number of receivers can be reduced while ensuring the accuracy of the measurement results, thus lowering costs. The number of receivers, M, is rounded up, and the middle section has sufficient space for installation. Furthermore, this arrangement of receivers better guarantees the accuracy of the measurement results.

[0013] For example, This configuration is more suitable for the height of most containers and is more practical.

[0014] For example, This configuration is more suitable for the height of most containers and is more practical.

[0015] For example, the transmitter includes a TOF infrared transmitter, and the receiver includes a TOF infrared receiver. Thus, the water sampling device employing both a TOF infrared transmitter and a TOF infrared receiver acquires more accurate information, ensuring the accuracy of the measurement results. It also has lower costs and is more suitable for mass production.

[0025] In the following description, numerous details are provided to enable a thorough understanding of the present invention. However, those skilled in the art will appreciate that the following description merely illustrates preferred embodiments of the present invention, which may be practiced without one or more of these details. Furthermore, to avoid confusion with the present invention, some technical features well-known in the art have not been described in detail.

[0026] To fully understand the embodiments of this utility model, a detailed structure will be presented in the following description. Obviously, the implementation of the embodiments of this utility model is not limited to the specific details familiar to those skilled in the art. Preferred embodiments of this utility model are described in detail below; however, in addition to these detailed descriptions, this utility model may have other embodiments.

[0027] This utility model provides a water dispensing device. This water dispensing device can be a countertop water purifier, a water dispenser, etc. (Refer to the reference...) Figure 1 and 4The water dispensing device 10 may include a main body 110 and a water dispensing element 120 disposed on the main body 110. The main body 110 may have a container placement area 1101 corresponding to the water dispensing element 120. Specifically, the container placement area 1101 can be used to place a container 20, such as a water cup, which can be placed in the container placement area 1101, and the water dispensing device 10 injects water into the water cup through the water dispensing element 120. A transmitter 130 for transmitting a measurement signal and a receiver 140 for receiving a measurement signal may be respectively disposed on opposite sides of the container placement area 1101. The measurement signal may be transmitted and received in the form of light waves. Alternatively, in some embodiments, the measurement signal may be ultrasonic waves. There are at least two transmitters 130, spaced apart along a predetermined direction XX from the water dispensing element 120 to the container placement area 1101. The number of receivers 140 is greater than the number of transmitters 130, and the multiple receivers 140 may be spaced apart along the predetermined direction XX. That is, multiple receivers 140 may correspond to one transmitter 130. Each transmitter 130 emits a measurement signal that covers a portion of the opposite area, and these areas may overlap. Taking two transmitters 130 and six receivers 140 as an example, the signal from one transmitter 130 covers four areas. The two receivers 140 in the middle are in overlapping areas and can be simultaneously covered by both transmitters 130, further improving measurement accuracy. It can be understood that the opposite receivers 140 can cover the signal transmission areas of all transmitters 130 along a predetermined direction XX. Receivers 140 are also electrically connected to a signal processing module. The signal processing module can obtain the measurement signal received by receivers 140 and determine the height of the container 20 within the container placement area 1101 based on the measurement signal. The predetermined direction XX can be understood as the height direction of the container 20 within the container placement area 1101.

[0028] Reference Figure 4 The dashed lines schematically illustrate the measurement signal emitted by transmitter 130. Each transmitter 130 has a specific optimal transmission range, which is fan-shaped and has an included angle α. The included angle α cannot be too large; if α is too large, the signal may experience diffuse reflection and intensity reduction, easily leading to misreception or failure to receive the signal by receiver 140, thus affecting the accuracy of the measurement. Setting at least two transmitters 130 in a predetermined direction XX can increase the total coverage of the measurement signal. For example, the number of transmitters 130 can be two.

[0029] The transmitter 130 transmits a measurement signal. When a container 20 is placed in the container placement area 1101, the container 20 may partially block the measurement signal. Some of the multiple receivers 140 on the other side can receive the measurement signal. Based on the receivers 140 that received the measurement signal and / or those that did not, the height of the container 20 can be measured. Specifically, refer to... Figure 5 Taking an embodiment with two transmitters as an example, the transmitter at a relatively higher position is referred to as the first transmitter 1301, and the transmitter at a relatively lower position is referred to as the second transmitter 1302. Two receivers are schematically labeled in the figure: the one at a relatively higher position is the first receiver 1401, and the one at a relatively lower position is the second receiver 1402. The distance from the first transmitter 1301 to the bottom (in some embodiments, the placement platform 1140) is M1, and the distance from the second transmitter 1302 to the bottom is M2. The distance from the first receiver 1401 to the bottom is M4, and the distance from the second receiver 1402 to the bottom is M3. The horizontal distance between the first receiver 1401 and the first transmitter 1301 (in some embodiments, between the first column and the second column) is L2, and the horizontal distance between the sidewall of the container 20 closest to the first transmitter 1301 and the first transmitter 1301 is B. The angle between the line connecting the second transmitter 1302 and the first receiver 1401 and the horizontal plane is φ1, and the angle between the line connecting the first transmitter 1301 and the second receiver 1402 and the horizontal plane is φ2. Therefore, it can be concluded that... Therefore, the container height is... and By combining the information, the height H of container 20 and the horizontal distance B between the side wall of container 20 near the first transmitter 1301 and the first transmitter 1301 can be obtained. The height H of container 20 can be measured more accurately by using the first transmitter 1301, the second transmitter 1302, the first receiver 1401 and the second receiver 1402.

[0030] In existing technology, multiple light wave emitters are spaced apart and positioned on one side of a water cup, while multiple light wave receivers are spaced apart and positioned on the other side of the cup, with a one-to-one correspondence between the emitters and receivers. When the water cup is placed in the cup, it blocks some light, and the height of the cup can be determined based on the light waves not received by the receivers. However, because the receivers are spaced apart, if the edge of the area blocked by the cup falls within the gap between two receivers, the height of the cup is usually calculated based on the height of the upper receiver, which does not yield an accurate result. To increase measurement accuracy, some water dispensing devices arrange light wave emitters continuously on one side of the cup and receivers continuously on the other side, but this is too costly.

[0031] The water outlet device 10 provided in this application transmits a measurement signal through each transmitter 130. The transmitter 130, the upper edge of the container 20, and the corresponding receiver 140 form a line. By using at least two transmitters 130 arranged along a predetermined direction, at least two lines can be obtained. Using at least two lines allows for a more accurate measurement of the height of the container 20, and at a lower cost.

[0032] For example, refer to Figure 1 The main body 110 may include a first column 1110, a second column 1120, and an upper crossbeam 1130 connecting the first column 1110 and the second column 1120. The length directions of both the first column 1110 and the second column 1120 are the same as a predetermined direction XX, and the first column 1110 and the second column 1120 are arranged opposite to each other. A transmitter 130 may be disposed on the first column 1110, a receiver 140 may be disposed on the second column 1120, and a water outlet 120 may be disposed on the upper crossbeam 1130. A container placement area 1101 is formed between the first column 1110, the second column 1120, and the upper crossbeam 1130. Figure 1 In the illustrated embodiment, the first column 1110 can be located on the left side of the container placement area 1101, the second column 1120 can be located on the right side of the container placement area 1101, and the upper crossbeam 1130 is located above the container placement area 1101. This arrangement of the first column 1110, the second column 1120, and the upper crossbeam 1130 better ensures the installation of the transmitter 130, the receiver 140, and the water outlet 120. The container 20 is placed within the container placement area 1101, and the space between the first column 1110, the second column 1120, and the upper crossbeam 1130 forms the container placement area 1101, which better accommodates the container 20, ensuring accurate measurement of the container height. In other embodiments, the water outlet can be located in other positions; for example, the main body can include a lower crossbeam connected to the bottom of the first column and the bottom of the second column, and the water outlet can be located on the lower crossbeam.

[0033] For example, in conjunction with reference Figure 1 and 4 The main body 110 may further include a placement platform 1140, which can be used to place the container. The top surface of the placement platform 1140 may have a hollow structure, and a water storage space for temporarily storing excess water can be formed inside the placement platform 1140. The placement platform 1140 and the water outlet 120 can be arranged opposite each other at both ends of the container placement area 1101. There is a first distance L1 between the placement platform 1140 and the water outlet 120, and a second distance L2 between the first column 1110 and the second column 1120. Each emitter 130 faces the second column 1120 and has an included angle α of its emission range. The number of emitters 130 is N. Where N is a natural number, The rounding sign is used for rounding up. For example, if the formula calculates a value of 1.2, N is 2; if the formula calculates a value of 3.0, N is 3. This setting ensures that the total transmission range of the multiple transmitters 130 is large enough to better cover multiple receivers and guarantee the accuracy of the measurement data. Preferably, In this way, the number of transmitters 130 can be reduced while ensuring the accuracy of the measurement data, resulting in lower costs. For example, if the first distance L1 is 200mm, the second distance L2 is 80mm, and the included angle α of the transmission range is 30°, the calculation yields 1.3, i.e., N≥2, and the number of transmitters 130 is at least two.

[0034] For example, in conjunction with reference Figure 1 and 4 Each receiver 140 has a receiving range of length L3 in the predetermined direction XX. Within the receiving range of the receiver 140, the receiver 140 can receive the measurement signal. The number of receivers 140 is M. Where M is a natural number, The rounding sign is used for rounding down. For example, if the formula calculates a value of 9.2, then M is 9. It can be understood that in some cases, the receiving range of receiver 140 is the area occupied by its lens, that is, the space occupied by the lens itself. This setting ensures that the total receiving range of multiple receivers 140 is large enough to better receive measurement signals and guarantee the accuracy of measurement data. Furthermore, it avoids interference between multiple receivers 140. Preferably, In this way, the number of receivers 130 can be reduced while ensuring the accuracy of the measurement data, resulting in lower costs. For example, the first distance L1 is 200mm, and the receiving range of each receiver 130 in the predetermined direction XX is 9.5mm in length L3. Calculation yields 21.05, i.e., M≤21, and the maximum number of receivers is 21.

[0035] For example, in conjunction with reference Figure 3 and 4 Each transmitter 130 has a first reflector 1510 and a second reflector 1520 correspondingly arranged in a predetermined direction XX. The first reflector 1510 and the second reflector 1520 are located at the upper and lower ends of the transmitter 130, respectively. The first reflector 1510 is closer to the upper crossbeam 1130 relative to the transmitter 130, that is, the first reflector 1510 is located above the transmitter 130. The first reflector 1510 and the first column 1110 have a first included angle β1, where 90°≥β1≥67.5°. It can be understood that the transmission range of the measurement signal of the transmitter 130 is related to the angle between the first reflector 1510 and the second reflector 1520. The larger the first included angle β1, the smaller the included angle between the measurement signal emitted by the first reflector 1510 and the transmitter 130. The first reflector 1510 configured in this way can prevent the intensity of the measurement signal emitted by the transmitter 130 from decreasing, avoid diffuse reflection, and thus prevent the receiver 140 from failing to receive the measurement signal or misreceiving the measurement signal, thereby ensuring the accuracy of the measurement.

[0036] For example, continue to refer to Figure 4 and 5 The second reflector 1520 is further away from the upper crossbeam 1130 relative to the transmitter 130, and there is a second included angle β2 between the second reflector 1520 and the second column 1120, where 90° ≥ β2 ≥ 67.5°. The larger the second included angle β2, the smaller the angle between the measurement signal emitted by the second reflector 1520 and the transmitter 130. This arrangement of the second reflector 1520 can prevent a decrease in the intensity of the measurement signal emitted by the transmitter 130, avoid diffuse reflection, and thus prevent the receiver 140 from failing to receive the measurement signal or misreceiving the measurement signal, ensuring the accuracy of the measurement. It is understood that the first reflector 1510 and the second reflector 1520 can be symmetrically arranged at the upper and lower ends of the transmitter 130. The included angle between the first reflector 1510 and the second reflector 1520 is not greater than 45°. Preferably, the included angle between the first reflector 1510 and the second reflector 1520 is 45°. That is, the launch angle of one launcher 130 is 45°.

[0037] For example, continue to refer to Figure 4 and 5 The second column 1120 may include a first part, a second part, and an intermediate part located between the first part and the second part. The first part is located at the end of the second column 1120 near the water outlet 120, and the second part is located at the end of the container placement area 1101 away from the water outlet 120. Multiple receivers 140 are disposed in the intermediate part. The first part has a first part length H1, the second part has a second part length H2, and the intermediate part has a third part length H3. The receiving range of each receiver 140 has a length L3 in a predetermined direction XX, and the number of receivers 140 is M. Where M is a natural number, The symbol is rounded up. This can be understood as follows: the container 20 is typically neither too high nor too low, so when placed in the container placement area 1101, it usually does not occupy the higher part (corresponding to the first part) or the lower part (corresponding to the second part) of the container placement area 1101. The receiver 140 is located in the middle part, which reduces the number of receivers 140 while ensuring the accuracy of the measurement results, thus lowering costs. The number M of receivers 140 is rounded up, providing sufficient space in the middle part for installation, and this arrangement of receivers 140 better ensures the accuracy of the measurement results. For example, with H1 being 10mm, H2 being 40mm, H3 being 150mm, and L3 being 9.5mm... That is, M≤16, meaning the maximum number of receivers 130 is 16.

[0038] For example, multiple receivers 140 can be evenly arranged along a predetermined direction XX. It is understood that the denser the receivers 140 are arranged along the predetermined direction XX, the more accurate the measurement data, but correspondingly, the cost will be higher. When the maximum number of receivers 140 is 16 and the number of transmitters 130 is 2, the number of receivers 140 can be set to 8. In this case, the measured height error of the container 20 is approximately 9.5 mm, and the water output of the water outlet device 10 typically reaches a maximum of 80% of the container 20. In actual use, this setting will not affect the normal operation of the water outlet device 10 and can effectively reduce costs.

[0039] For example, For example, when the second column is 200mm in length, the first section can be no more than 10mm. This design is more practical and better suited for most containers with a height of 20mm.

[0040] For example, For example, if the entire second column is 200mm, the second section can be no more than 50mm. This design is more suitable for most containers with a height of 20mm, making it more practical.

[0041] For example, the transmitter 130 may include a TOF infrared transmitter, and the receiver 140 may include a TOF infrared receiver. TOF (Time of Flight) refers to the technology of measuring the time it takes for an object, particle, or wave to travel a certain distance in a fixed medium (where the medium, distance, and time are all known or measurable), thereby further understanding certain properties of ions or media. Specifically, the transmitter 130 may be a TOF infrared emitting LED, and the receiver 140 may be a TOF infrared receiving lens. Thus, a water sampling device using a TOF infrared transmitter and receiver obtains more accurate information, ensuring the accuracy of the measurement results. It also has lower costs and is more suitable for mass production.
