Description

Technical Field

[0001] The utility model relates to the field of electrical appliances, in particular to household water purification equipment, and specifically to an adaptive water dispenser with integrated water purification and drinking functions. Background Art

[0002] With the improvement of people's living quality, the awareness of drinking water safety has been gradually strengthened. Household water dispensers with integrated water purification and drinking functions have the advantages of convenience, safety and health, and have been rapidly popularized. Along with the development of technology, according to different application scenarios, the functions of water dispensers are continuously iterated and updated. For example, from simple water purification functions, they have developed into water dispensers with multiple functions such as water storage, heating, refrigeration, and carbonated water production. And according to different household use area scenarios, they have further developed into under-counter, countertop, wall-mounted and other forms of water dispensers to meet the installation and use needs of different users.

[0003] Regardless of how rich the functions of the water dispenser are, users need to use a water receiving container, such as a water cup, to receive the purified water from the water outlet of the water dispenser. In order to automatically control the water discharge volume of the water outlet, various sensors are used in the prior art to sense the water level height in the water receiving container to achieve this function. For example, Chinese Patent Publication No. CN103948313A, with a publication date of July 30, 2014, and a title of: An intelligent water dispenser, can measure the water level height in the water cup through a liquid level sensor also provided under the control panel, cooperate with a height detection sensor for measuring the height of the water cup, and use an MCU for control, so as to realize the automatic water filling function of the water dispenser and prevent the situation of scalding due to overfilling of the water cup. Chinese Patent Publication No. CN 105996763 A, with a publication date of October 12, 2016, and a title of: An invention patent application for an intelligent water dispenser and its control method, also adopts a similar design.

[0004] In the design of the automatic water filling function of the existing water dispenser, due to the different spaces for accommodating the water receiving container between the water outlet and the water receiving table in water dispensers of different specifications, the sizes and styles of water receiving containers, such as water cups, are diverse. Especially when using a water cup with a relatively low height to receive water, the distance between the water cup and the water outlet may be relatively far, and the water discharged from the water outlet may stay above the water cup for a long time before falling into the water cup. The discharged water is likely to splash around. Especially when discharging hot water, it may scald the user, the hot water mist is likely to disperse, the water temperature is affected, and pollutants such as dust in the air will dissolve in the water. Moreover, during the water discharging process, the position of the water cup may change, resulting in the actual water receiving height of the water cup being inconsistent with the detected height, the water in the water cup cannot be filled properly, or the water overflows.

[0038] Next, the present utility model will be described in detail with reference to the accompanying drawings. What is described here is only the preferred embodiment of the present utility model, and those skilled in the art can think of other ways to implement the present utility model on the basis of the preferred embodiment, and other ways also fall within the scope of the present utility model.

[0039] like Figure 1 and Figure 2 As shown, a water purifier is schematically shown, which has a body 100, a water spout assembly 200 and a water receiving platform 300. The body 100 is the main part of the water purifier, and has a variety of functional components inside, such as a filter element, a water channel plate, a heating component, etc., to filter and purify raw water, distribute water channels, and heat purified water. These functional components are prior art and will not be described here. One side of the body 100 has a water receiving area 110, such as the front side shown in the figure. This embodiment is based on Figure 1 and Figure 2 The water nozzle assembly 200 is provided with a water nozzle 220 with a water outlet, which is used to discharge the purified water in the body 100 through the water outlet of the water nozzle 220 to the outside of the body 100 so as to receive water in a water receiving container, such as a cup. The water receiving platform 300 is used to place the water receiving container so that the water receiving container receives the water discharged by the water nozzle 220. The water nozzle assembly 200 and the water receiving platform 300 are arranged in the water receiving area 110 of the body 100 according to the vertical position in the height direction, and the water receiving area 110 of the body 100 is observed. Figure 1 and Figure 2 As shown, the faucet assembly 200 is located at the front side of the machine body 100 near the top, and the water receiving platform 300 is located at the front side of the machine body 100 near the bottom. It should be understood that the water receiving platform 300 can be a water receiving box installed at the front side of the machine body 100 near the bottom, or the water receiving platform 300 and the machine body 100 are separate, for example, the table where the water purifier is placed can also be used as the water receiving platform 300, as long as it can be used to place the water receiving container.

[0040] In this embodiment, the faucet assembly 200 can be slidably disposed on the body 100 in the height direction through a linear guide pair 700. The faucet assembly 200 is transmission-connected to the driving mechanism 500. The driving mechanism 500 can drive the faucet assembly 200 to slide up and down along the body 100 to adjust the height of the water outlet of the faucet 220 relative to the water receiving platform 300. Figure 2 As shown in FIG. 1 , the water outlet of the water spout 220 is located at the bottom of the water spout assembly 200, so that the water spout 220 can discharge water downwards, so that the water cup can receive water on the water receiving platform 300. Figure 2As shown, near the water outlet of the water nozzle 220 on the water nozzle assembly 200, that is, at the bottom of the water nozzle assembly 200, a sensor assembly 400 is provided. The sensor assembly 400 is configured to slide up and down with the water nozzle assembly 200 to detect the position information of the water receiving container placed in the water receiving area 110, such as the water receiving container placed above the water receiving table 300, and the water receiving water level information in the water receiving container. The position information and the water level information can be, for example, the height data of the upper edge of the water cup or a specific marking point from the water nozzle assembly 200, and the height data of the upper surface of the water in the water cup from the water nozzle assembly 200. One or more sensor assemblies 400 can be provided. For example, when one sensor assembly 400 is provided, one sensor assembly 400 can simultaneously detect the position information of the water receiving container placed in the water receiving area 110 and the water receiving water level information in the water receiving container. For example, when multiple sensor assemblies 400 are provided, the position information of the water receiving container and the water receiving water level information in the water receiving container can be detected separately. As Figure 3 shown, both the driving mechanism 500 and the sensor assembly 400 are electrically connected to the controller 600. The controller 600 is configured to receive and process the signals of the position information of the water receiving container and the water receiving water level information detected by the sensor assembly 400, and then control the action of the driving mechanism 500 to control the height of the water outlet of the water nozzle 220 from the water receiving container and the water filling amount of the water nozzle 220. The controller 600 can adopt a PLC controller, such as an MCU.

[0041] During use, the water nozzle assembly 200 is in the highest position in the initial state. When a water cup is placed on the water receiving table 300, the sensor assembly 400 senses that a cup is placed in it and detects the height of the cup. Then, it transmits the signal to the controller 600. The controller 600 calculates the descending height of the water nozzle assembly 200 and the water receiving height of the water cup. The controller 600 controls the driving mechanism 500 to drive the water nozzle assembly 200 to automatically descend to a preset position above the water cup from the water outlet of the water nozzle 220. Then, the controller 600 controls the water nozzle 220 to discharge water. When the water level reaches the preset height, it controls the water nozzle 220 to stop discharging water. Finally, the controller 600 controls the driving mechanism 500 to drive the water nozzle assembly 200 to rise and return to the initial position to prepare for the next water receiving. During the descent of the water nozzle assembly 200, the sensor assembly 400 can detect the height of the water nozzle 220 from the water cup multiple times to accurately control the descending height of the water nozzle assembly 200 and avoid the descending error of the water nozzle assembly 200 and the water receiving height error of the water cup caused by the change of the water cup position.

[0042] In this solution, the water nozzle assembly 200 is designed to be a liftable structure. The sensor assembly 400 detects the height of the water receiving container placed on the water receiving platform 300. The controller 600 controls the drive mechanism 500 to drive the water nozzle assembly 200 to lift automatically, adjusts the water outlet of the water nozzle 220 to a preset position above the water receiving container, such as a slightly higher position, and then discharges water. Moreover, it controls the discharge height to be lower than the water holding height of the water receiving container, so that the water flowing out of the water nozzle 220 directly enters the water receiving container, effectively avoiding the splashing of water around when discharging water. In particular, it can avoid the possible scalding of users when discharging hot water. The hot water mist is likely to disperse, and it also effectively keeps warm and prevents pollutants such as dust in the air from mixing into the water. At the same time, the sensor assembly 400 lifts together with the water nozzle assembly 200 and can detect the change in the height of the water receiving container multiple times during the lifting process to effectively ensure the accuracy of the final water receiving height.

[0043] As Figure 4 shown, as the specific structure of the drive mechanism 500, the drive mechanism 500 includes a power unit 510 and a transmission unit 520. The power unit 510 provides the power required for the lifting of the water nozzle assembly 200, and the transmission unit 520 transmits the power of the power unit 510 to the water nozzle assembly 200. The power unit 510 can adopt, for example, a motor, a hydraulic cylinder, a pneumatic cylinder, a pump, etc. As a way to implement the water purifier, it is preferably to use a motor as the power unit 510. The transmission unit 520 can adopt any existing transmission method, for example, it can be formed by the meshing of a gear 521 and a rack 522, or by the cooperation of a lead screw and a nut, or a pressure cylinder or a push rod, or by the cooperation of a pulley and a transmission belt. As an illustration, in this embodiment, the transmission unit 520 is formed by the meshing of a gear 521 and a rack 522, and the power unit 510 uses a motor. The motor is installed on the body 100, the output shaft of the motor is installed with the gear 521, the rack 522 is installed on the water nozzle assembly 200, and the rotating shaft of the motor drives the gear 521 to rotate. The gear 521 meshes with the rack 522 for transmission, driving the water nozzle assembly 200 to achieve a lifting motion.

[0044] To better install the sensor assembly 400 on the water nozzle assembly 200, as Figures 9 to 13 shown, in this embodiment, the water nozzle assembly 200 includes a water nozzle frame 210, a water nozzle 220, a sliding member 230, and a cover plate 240. The sliding member 230 is integrally in the shape of a rectangular plate with a relatively long vertical direction. The water nozzle frame 210 is installed at a middle position on the front side of the sliding member 230. An accommodation cavity 211 is formed inside the water nozzle frame 210, and an opening 212 communicating with the accommodation cavity 211 is provided on the front side of the water nozzle frame 210. The cover plate 240 covers the opening 212, and the water nozzle 220 of the water nozzle assembly 200 is installed in the accommodation cavity 211 of the water nozzle assembly 200. Combining Figure 13As shown, the bottom of the receiving cavity 211 of the faucet holder 210 is the faucet plate 213. An open faucet through-hole 2132 is formed on the faucet plate 213, which is an arc-shaped notch here. A corresponding arc-shaped notch is also provided on the cover plate 240. When the cover plate 240 is closed on the faucet holder 210, the water outlet of the faucet 220 can be stuck at the notch formed between the faucet plate 213 and the cover plate 240. This cooperation mode of the faucet plate 213 and the cover plate 240 not only meets the water discharge requirement of the water outlet of the faucet 220, but also isolates the lower part of the water outlet of the faucet 220 from the receiving cavity 211 of the faucet assembly 200, preventing dust from entering the receiving cavity 211. In this embodiment, the cross-section of the cover plate 240 is a U-shaped structure, which can cover the front side and the left and right sides of the faucet holder 210, making it aesthetically pleasing as a whole. Moreover, the cover plate 240 is snap-connected to the faucet holder 210, which is convenient for disassembly and assembly.

[0045] Meanwhile, the sensor assembly 400 is located in the receiving cavity 211 of the faucet assembly 200. A sensing hole 2131 is formed on the faucet plate 213 of the faucet holder 210. In this embodiment, the sensing hole 2131 is located behind the faucet through-hole 2132. The detection element 422 of the sensor assembly 400 faces the sensing hole 2131 and can perform detection through the sensing hole 2131. Both the faucet 220 and the sensor assembly 400 are arranged in the receiving cavity 211 on the faucet holder 210, and the opening 212 of the receiving cavity 211 is closed by the cover plate 240. The faucet assembly 200 has a high degree of integration and a compact structure, which is convenient for the cooperation and assembly of the faucet 220 and the sensor assembly 400, improves the detection accuracy, and the overall faucet assembly 200 is simple and aesthetically pleasing.

[0046] Such as Figure 13 and Figure 14As shown in the figure, in this embodiment, the sensor assembly 400 includes a box body 410 and a sensor 420. The box body 410 is installed in the accommodation cavity 211 of the faucet assembly 200, and the box body 410 is provided with a cavity 411 that can accommodate the sensor 420. A pair of perforated ear plates 412 are provided on the outer side walls of the opposite sides of the box body 410, and the box body 410 is fixed to the faucet bracket 210 by screws through the pair of perforated ear plates 412. The sensor 420 includes a circuit board 421 and a detection element 422 installed on the circuit board 421. The circuit board 421 is installed in the cavity 411, and a through detection port 413 is provided at the bottom of the cavity 411, and the detection element 422 faces the detection port 413. The detection element 422 can be provided with one or more. For example, when the detection element 422 is one, the position information of the water receiving container and the water receiving level information in the water receiving container are detected simultaneously; when the detection element 422 is two, one can detect the position information of the water receiving container, and the other can detect the water receiving level information in the water receiving container. In the latter case, both detection elements 422 can also detect the position information of the water receiving container and the water receiving level information in the water receiving container at the same time, which plays a role of mutual verification to prevent errors; when the detection element 422 is more than two, each detection element 422 can be set to detect the position information of the water receiving container or the water receiving level information in the water receiving container separately as needed, or detect the position information of the water receiving container and the water receiving level information in the water receiving container at the same time. The detection element 422 can adopt any existing methods such as infrared light detection, ultraviolet light detection, ultrasonic detection, and radar wave detection. The sensor assembly 400 is modularly designed and installed in the accommodation cavity 211 of the faucet assembly 200 through the box body 410. The sensor assembly 400 is installed compactly and conveniently, and the box body 410 has a protective effect on the sensor 420.

[0047] Here, the cross-section of the box body 410 is square. Of course, it can also be other shapes. The shape of the sensing hole 2131 on the accommodation cavity 211 is adapted to the outer shape of the box body 410, that is, the sensing hole 2131 is a square hole, and the box body 410 is embedded in the sensing hole 2131. The installation of the sensor assembly 400 is more stable and reliable, and the overall appearance of the faucet assembly 200 is beautiful. In order to facilitate the installation of the circuit board 421 in the box body 410, a clamping protrusion 414 is provided on the inner side wall of the cavity 411 of the box body 410, and the circuit board 421 is snapped into the cavity 411 through the clamping protrusion 414. The clamping protrusion 414 can be provided with one or more, preferably two. The two clamping protrusions 414 are provided on the opposite inner side walls of the cavity 411 of the box body 410, and the clamping is firm.

[0048] To implement the lifting and sliding structure of the faucet assembly 200, in combination with Figures 5 to 8As shown in the figure, two sliding support surfaces 120 are arranged vertically on the body 100 and spaced left and right. The linear guide pair 700 includes two sliding pressure plates 710 extending in the vertical direction. The sliding pressure plates 710 are fixed to the body 100, for example, by bolts. The two sliding pressure plates 710 are respectively arranged corresponding to the two sliding support surfaces 120 on the body 100, and a chute is formed between the sliding pressure plate 710 and the sliding support surface 120. Of course, the structural form of the linear guide pair 700 is not limited to this, and any other structure that can achieve linear sliding can also be used, such as the cooperation of a guide rod and a guide sleeve, the cooperation of a slider and a slide rail, etc. As Figure 9 and Figure 10 shown, a pair of sliding plates 231 are symmetrically arranged on the left and right sides of the sliding member 230 in the water nozzle assembly 200. The sliding plates 231 are slidably engaged in the chute. As an optimized method, a slider 232 is arranged on one side of the sliding plate 231 opposite to the sliding pressure plate 710. The slider 232 can be a square block, a pulley, etc., and the structural form is not limited. The material can be rubber or polyurethane. In this structural form, the slider 232 on the sliding plate 231 of the water nozzle assembly 200 is clamped in the chute formed between the sliding pressure plate 710 and the sliding support surface 120, and the sliding bearing capacity is good, which can meet the lifting and sliding requirements of the water nozzle assembly 200, and can adjust the sliding damping of the lifting of the water nozzle assembly 200. In addition, in order to limit the lifting height of the water nozzle assembly 200, upper limit members 711 and lower limit members 712 are respectively provided at the upper and lower ends inside the sliding pressure plate 710 for limiting the upper limit and lower limit of the slider 232 in the vertical direction. The upper limit member 711 and the lower limit member 712 are made of elastic materials such as rubber or polyurethane for elastic blocking to avoid noise and vibration; of course, limit switches can also be installed on the upper limit member 711 and the lower limit member 712. When the limit switch senses the slider 232, the lifting action can be controlled to stop.
