Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to a drinking water device. Background Technology

[0002] Tea bar machines are small household appliances that combine drinking water and tea brewing functions, and are loved by many consumers.

[0003] In existing tea bar machines, multiple detection points are usually set inside the kettle to detect the water level. As the kettle is boiled repeatedly, limescale easily forms inside. This limescale adheres to the detection points, affecting the accuracy of the water level detection results. Furthermore, the water quality varies greatly in different areas, which also affects the accuracy of the detection points.

[0004] Some kettles use a level gauge to detect the water level. The kettle needs to have a flow channel to cooperate with the level gauge. In order to ensure that the level gauge moves vertically without deviation, the size of the flow channel is generally set to be small. Scale can easily accumulate inside, affecting the movement of the level gauge and thus causing inaccurate water level detection. Utility Model Content

[0005] The purpose of this invention is to provide a drinking water device that can solve the problem of inaccurate water level detection results caused by scale or water quality.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0009] A kettle, which can be placed in the placement position, the kettle includes a kettle body and a float, the kettle body has an inner cavity and a flow channel communicating with the inner cavity, the float is disposed in the flow channel and is gap-fitted with the flow channel so as to rise and fall with the water level in the flow channel.

[0010] A sensor is disposed on the upright plate. The sensor can sense the float located at a corresponding height. The sensing range of the sensor on the surface of the kettle extends circumferentially along the kettle.

[0011] As an alternative to the aforementioned drinking water equipment, the sensing element is a magnetic switch, which is elongated and the float is made of magnetic material.

[0012] As an alternative to the above-mentioned drinking water equipment, the flow channel is located on the side of the kettle body facing the vertical plate;

[0013] And / or, the float is a float ball, and the fitting gap between the flow channel and the float ball is 0.1-0.6 times the diameter of the float ball.

[0014] As an alternative to the above-mentioned drinking water equipment, the side surface of the upright plate facing the placement position forms a positioning groove along the circumference of the placement position, and part of the kettle body can be placed in the positioning groove.

[0015] As an alternative to the above-mentioned drinking water equipment, the bottom end of the flow channel is connected to the inner cavity, and the cross-sectional area of ​​the bottom end of the flow channel gradually decreases from top to bottom;

[0016] Alternatively, the flow channel includes a connected upper flow channel and a lower flow channel, the cross-sectional area of ​​the upper flow channel is larger than the cross-sectional area of ​​the lower flow channel, and the float is located in the upper flow channel.

[0017] As an alternative to the above-mentioned drinking water equipment, the kettle body includes a kettle body and a flow channel cover that can be detachably installed inside the kettle body, the flow channel cover and the inner wall of the kettle body forming the flow channel.

[0018] As an optional solution for the above-mentioned drinking water equipment, the inner wall of the kettle body is provided with a lug, and the flow channel cover is provided with a positioning component. The positioning component includes a mating part and a limiting part. The mating part passes through the lug, and the limiting part abuts against the lug from above.

[0019] Alternatively, two support walls are arranged opposite each other on the inner wall of the kettle body, and each support wall is provided with a groove. The top of the groove and the end facing the other support wall are open structures, and the opposite side edges of the flow channel cover can be slidably inserted into the corresponding groove.

[0020] Alternatively, the flow channel cover may be snapped and fixed to the body of the kettle.

[0021] As an optional solution for the above-mentioned drinking water equipment, the upright plate and the kettle cooperate to form a foolproof structure.

[0022] As an optional solution for the above-mentioned drinking water equipment, the foolproof structure includes a protrusion and a recess, one of which is disposed on the outer peripheral surface of the kettle and the other is disposed on the body. After the protrusion and the recess are engaged, the sensing element is correspondingly disposed with the float.

[0023] Alternatively, the kettle body includes a spout and a handle, and the side surface of the upright plate facing the placement position forms a positioning groove along the circumference of the placement position.

[0031] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0032] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0034] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0035] This embodiment provides a drinking water device, such as... Figure 1 As shown, the device includes a main body and a kettle 200. The main body includes a shelf 110 with a placement position on it, where the kettle 200 can be placed for filling or boiling water.

[0036] Specifically, the machine body also includes a vertical plate 120 and a machine head 130. The vertical plate 120 is located on the shelf 110, and its top is connected to the machine head 130. The machine head 130 is provided with a water inlet 140, which is located above the placement position. When the kettle 200 is placed on the placement position, the water inlet 140 is directly opposite the water inlet on the kettle 200, and water can flow out from the water inlet 140 and enter the kettle 200 through the water inlet under the action of gravity.

[0037] Alternatively, the water dispenser can be a tea bar machine or other equipment.

[0038] To detect the water level in the kettle 200 and prevent water from overflowing, the kettle 200 includes a kettle body 210 and a float 220. The kettle body 210 has an inner cavity and a flow channel communicating with the inner cavity. The float 220 is disposed in the flow channel and is fitted with the flow channel with a gap so that the float 220 can rise and fall with the change of water level in the kettle 200. A sensor 300 is disposed on the upright plate 120. The sensor 300 can sense the float 220 located at a corresponding height to detect the water level in the kettle 200.

[0039] By cooperating with the external sensor 300 and the internal float 220 of the kettle 200, the water level inside the kettle 200 can be detected. The movement of the float 220 is only related to the water level inside the kettle 200 and is not affected by the water quality. This can satisfy the user's need to detect the water level inside the kettle 200 when brewing various beverages.

[0040] In existing drinking water equipment that uses a float and sensor to detect water level, the flow channel is designed to be small in size and the gap between the float and the flow channel is small in order to ensure the positional accuracy of the sensor and the float. This results in even a small amount of scale adhering to the flow channel, which can interfere with the rise and fall of the float and affect the timeliness and accuracy of the water level detection results.

[0041] To address the aforementioned issues, in this embodiment, the float 220 is fitted with a gap in the flow channel, allowing it to move horizontally within the channel and increasing its range of motion. Simultaneously, to ensure timely and accurate detection of the float 220 by the sensor 300, the sensing range of the sensor 300 on the surface of the kettle 200 extends circumferentially along the kettle 200. This ensures that even after the float 220 has moved horizontally within the flow channel, the sensor 300 can still detect its presence promptly. This design not only increases the gap between the float 220 and the flow channel, reducing interference from scale buildup on the inner wall of the flow channel, but also increases the sensing range of the sensor 300, ensuring its ability to detect the float 220 and improving the timeliness and accuracy of water level detection.

[0042] In order to make the sensing range of the sensor 300 on the surface of the kettle 200 a long strip extending along the circumference of the kettle 200, the sensor 300 can be in the shape of a strip to increase its sensing range.

[0043] In some embodiments, the sensing range of the sensor 300 on the surface of the kettle 200 can cover the area where the flow channel is located, so that the float 220 located in the flow channel is always within the sensing range of the sensor 300. The float 220 can move horizontally anywhere in the flow channel without affecting the detection of the water level.

[0044] To enable the sensor 300 to detect the float 220 inside the kettle 200 from the outside of the kettle 200, the sensor 300 can be a magnetic switch, and the float 220 is made of a corresponding magnetic material. A magnetic switch is a proximity switch that does not require direct contact. When the float 220 enters the sensing range of the magnetic switch as the water level rises or falls, the magnetic field generated by the magnetic switch changes, and this change is converted into an electrical signal, thereby achieving the function of detecting the position of the float 220.

[0045] In other embodiments, the sensing element 300 may also be other proximity switches, and the material of the float 220 may be adjusted according to the detection principle of the proximity switch.

[0046] It should be noted that the detection circuit of the magnetic switch is existing technology and will not be described in detail in this embodiment.

[0047] In some embodiments, the flow channel can be provided on the side of the vessel body 210 facing the upright plate 120 to shorten the horizontal distance between the float 220 and the sensor 300 and ensure detection effect.

[0048] In some embodiments, the float 220 is a float ball, and the cross-section of the flow channel can be circular, so that the inner wall of the flow channel has no corners, reducing the accumulation of scale on the inner wall surface of the flow channel, which is beneficial to the rise and fall of the float 220.

[0049] To ensure smoother movement of the float 220 and reduce the impact of scale buildup, the clearance between the flow channel and the float ball can be 0.1-0.6 times the diameter of the float ball. For example, the clearance between the flow channel and the float ball can be 0.1, 0.15, 0.2, 0.25, 0.3, 0.35, 0.4, 0.45, 0.5, 0.55, or 0.6 times the diameter of the float ball.

[0050] In some embodiments, the bottom end of the flow channel is connected to the inner cavity, which helps to ensure that the water level in the flow channel can quickly become level with the water level in the inner cavity when the water level in the inner cavity changes, so as to ensure the timeliness of water level detection.

[0051] To prevent the float 220 from detaching from the flow channel, the cross-sectional area of ​​the bottom end of the flow channel gradually decreases from top to bottom, so that the bottom end of the flow channel has a constricted structure, thus preventing the float 220 from falling off the bottom end of the flow channel.

[0052] In some embodiments, the flow channel includes an upper flow channel and a lower flow channel that are connected. The cross-sectional area of ​​the upper flow channel is larger than that of the lower flow channel. A limiting surface is formed at the connection between the upper and lower flow channels. The float 220 is located in the upper flow channel. The limiting surface restricts the float 220 from continuing to move downward, thereby preventing the float 220 from leaving the flow channel.

[0053] To facilitate the cleaning of scale and float 220 within the flow channel and ensure drinking water hygiene, the kettle body 210 includes a kettle body 211 and a detachable flow channel cover 212 installed within the kettle body 211. The flow channel cover 212 and the inner wall of the kettle body 211 form a flow channel. By removing the flow channel cover 212, the inner wall of the flow channel can be cleaned, ensuring the smooth raising and lowering of the float 220.

[0054] To facilitate the disassembly of the flow channel cover 212, in some embodiments, a lug is provided on the inner wall of the pot body 211, and a positioning member is provided on the flow channel cover 212. The positioning member includes a mating part and a limiting part. The mating part passes through the lug, and the limiting part abuts against the lug from above.

[0055] Optionally, the lug is provided with a through hole, and the mating part can be a plug rod. The plug rod is inserted into the through hole, and the flow channel cover 212 is suspended on the inner wall of the pot body 211 by the abutment of the limiting part and the lug, so as to fix the flow channel cover 212.

[0056] In some embodiments, two support walls are provided opposite to each other on the inner wall of the kettle body 211. The support walls are provided with grooves. The top of the groove and the end facing the other support wall are open structures. The two sides of the flow channel cover 212 can slide into the corresponding groove from the top to fix the flow channel cover 212 to the kettle body 211.

[0057] In some embodiments, the spout cover 212 and the kettle body 211 can be snapped together. For example, the spout cover 212 is provided with a first snap-fit ​​part, and the inner wall of the kettle body 211 is provided with a second snap-fit ​​part. The first snap-fit ​​part and the second snap-fit ​​part engage to fix the spout cover 212 and the kettle body 211. One of the first snap-fit ​​part and the second snap-fit ​​part can be a slot, and the other can be a buckle to achieve the snap-fit ​​engagement.

[0058] In some embodiments, such as Figure 2 As shown, the side surface of the upright plate 120 facing the placement position forms a positioning groove along the circumference of the placement position, and part of the kettle body 210 can be placed in the positioning groove. That is to say, the upright plate 120 can be semi-enclosed on one side of the kettle 200, which not only improves the positioning effect of the kettle 200 in the placement position, but also improves the appearance.

[0059] In some embodiments, the outer peripheral surface of the kettle body 211 is a cylindrical surface, and correspondingly, the groove wall of the positioning groove is an arc surface, so that the groove wall of the positioning groove can make good contact with the outer peripheral surface of the kettle body 211, making the fit between the kettle 200 and the upright plate 120 more compact.

[0060] To ensure that the float 220 inside the kettle 200 can be aligned with the sensor 300 after the kettle 200 is placed in the placement position, the upright plate 120 and the kettle 200 cooperate to form a foolproof structure, so that the kettle 200 can only be placed in the placement position at a fixed angle, ensuring the matching accuracy between the float 220 and the sensor 300.

[0061] In some embodiments, the foolproof structure includes a protrusion and a recess, one of which is disposed on the outer peripheral surface of the kettle 200, and the other is disposed on the body. After the protrusion and the recess engage, the sensor 300 is correspondingly disposed with the float 220. When the kettle 200 is placed, the position of the protrusion and the recess guides the user to place the kettle 200 correctly.

[0062] In some embodiments, the kettle 200 includes a spout 213 and a handle 214. The side surface of the upright plate 120 facing the placement position forms a positioning groove along the circumference of the placement position. The foolproof structure includes a spout clearance position and a handle clearance position, both disposed on opposite sides of the positioning groove on the upright plate 120. The spout clearance position is used to avoid the spout 213, and the handle clearance position is used to avoid the handle 214. The kettle 200's spout 213 and handle 214, combined with the upright plate 120, form a foolproof structure that is simple and helps reduce costs.

[0063] In some embodiments, two sensors 300 are provided, arranged vertically. One sensor 300 is used to sense the float 220 at a preset high water level to prevent water from overflowing from the kettle 200; the other sensor 300 is used to sense the float 220 at a preset low water level to add water to the kettle 200 in a timely manner to prevent dry burning.

[0064] In some embodiments, the drinking water device further includes a control component electrically connected to the sensor 300, which can control the water inlet 140 to open or close after the sensor 300 senses the corresponding float 220.

[0065] It should be noted that the control component and the connection circuit between the control component and the sensing element 300 are existing technologies and will not be described in detail in this embodiment.

[0066] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
