Description

Technical Field

[0001] The utility model relates to the technical field of beverage equipment, in particular to a beverage machine. Background Art

[0002] Beverage machines and other devices are often equipped with a water storage tray for storing wastewater. For brewing beverage machines, the water storage tray has not only a portion located on the front side of the beverage machine for holding the container, but also a portion extending into the interior of the beverage machine. This portion is also used to collect wastewater. This wastewater is mainly generated when cleaning the beverage machine, such as cleaning the pipes and cleaning the brewer. Usually, a pair of detection members are provided on the water storage tray, and the pair of detection members partially extend into the internal space of the water storage tray. When the liquid level of the wastewater reaches the height of the detection members, the pair of detection members form a closed loop and send a water full signal to remind the user to pour out the wastewater in the water storage tray in time, thereby avoiding excessive wastewater in the water storage tray. Excessive wastewater in the water storage tray can also easily make it inconvenient for the user to pour out the wastewater, and may even cause the wastewater to overflow from the water storage tray.

[0003] Taking a coffee machine as an example, when cleaning the brewer, scraping the brewer grounds, or making coffee, coffee powder or coffee grounds will enter the water reservoir. As the amount of coffee powder or coffee grounds increases, even after the waste water is poured out, the coffee powder or coffee grounds may still remain between the pair of detection parts and form a closed loop, resulting in a false detection of water fullness. Some coffee powder or coffee grounds may even fall directly between the pair of detection parts to form a closed loop.

[0004] Therefore, there is an urgent need for a beverage machine product that solves the above problems. Utility Model Content

[0016] As a further improvement of one embodiment of the present invention, a fixing seat is provided on the body, and the fixing seat includes a mounting plate and an extension plate. The mounting plate is fixed to the body, and the extension plate is fixed to the mounting plate.

[0031] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0032] Terms indicating spatial relative positions, such as "upper," "above," "lower," and "below," are used in this embodiment for ease of explanation to describe the relationship of one unit or feature relative to another unit or feature as shown in the accompanying drawings. Terms indicating spatial relative positions may be intended to encompass different orientations of the device during use or operation other than those shown in the drawings. For example, "upper," "lower," "left," "right," "horizontal," and "vertical" in this embodiment all refer to the spatial relative positions of the beverage dispenser when in normal use.

[0033] The terms "first," "second," "third," "fourth," etc., in this utility model are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Furthermore, it should be noted that, unless otherwise expressly specified or limited, the term "connection" should be understood in a broad sense. For example, a connection can be a direct connection or an indirect connection through an intermediate medium, and can be a fixed connection, a movable connection, a detachable connection, or an integral connection. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0034] For the convenience of description, taking the practical scenario of the beverage machine as a reference, it is defined as follows: the front side of the beverage machine is the side where the beverage machine discharges liquid, and the rear side of the beverage machine is the other side opposite to the front side.

[0035] In order to make those skilled in the art better understand the technical solution of the present invention, the following will be combined with the appended drawings in the embodiment of the present invention. Figure 1-9 , clearly and completely describe the technical solutions in the implementation methods of the present utility model.

[0036] One embodiment of the present invention provides a beverage machine, referring to Figure 1 and Figure 2 The beverage machine includes a body 10, a water storage tray 20, and a liquid level detection mechanism 30. The water storage tray 20 is detachably connected to the body 10. The liquid level detection mechanism 30 is arranged in the body 10, and the liquid level detection mechanism 30 is located above the water storage tray 20.

[0037] When the water reservoir 20 is installed in the machine body 10, waste water collected during the operation of the beverage machine is collected in the water reservoir 20. The liquid level detection mechanism 30 can detect the liquid level of the waste water in the water reservoir 20. When the liquid level of the waste water reaches the detection height set by the beverage machine program, the liquid level detection mechanism 30 will send a signal to the control system, causing the beverage machine to issue a reminder that the water reservoir 20 is full and to clean the water reservoir 20 in time.

[0038] The beverage machine mentioned above may be a coffee machine, a soybean milk machine, a juice machine, a tea machine, etc. In this embodiment, a coffee machine is taken as an example for description.

[0039] Reference Figure 1-3 The body 10 includes a housing cavity for accommodating a water reservoir 20. The water reservoir 20 is removably mounted within the housing cavity, which can accommodate at least a portion of the water reservoir 20. When the water reservoir 20 is installed within the body 10, the water reservoir portion of the water reservoir 20 is housed within the housing cavity. After the water reservoir 20 is removed, the water reservoir portion of the water reservoir 20 is separated from the housing cavity, facilitating the removal of wastewater and coffee residue from the water reservoir 20. Thus, the displacement of the water reservoir 20 relative to the housing cavity forms a movement path, which is defined as the installation path and / or removal path of the water reservoir 20 relative to the housing cavity. Typically, the water reservoir 20 is located at the bottom of the body 10 to facilitate the collection of wastewater and coffee residue.

[0040] The liquid level detection mechanism 30 is used to detect the liquid level within the water reservoir 20. It is movably connected to the housing 10 and is located along a movement path. As the water reservoir 20 moves along the movement path, the water reservoir 20 drives the liquid level detection mechanism 30 relative to the housing 10. In other words, because the liquid level detection mechanism 30 is located along the movement path, installation and removal of the water reservoir 20 interfere with the liquid level detection mechanism 30, causing it to move, making way for the water reservoir 20, thereby allowing the water reservoir 20 to be installed into or removed from the accommodating cavity.

[0041] Reference Figure 4The liquid level detection mechanism 30 includes a base 31 and a detection member 33. The base 31 is rotatably connected to the body 10, and the base 31 is set at the position of the accommodating cavity, and the detection member 33 is fixed to the base 31. The water storage tray 20 has a movable wall 22. During the movement of the water storage tray 20 along the moving path, the movable wall 22 contacts the base 31 to generate an external force on the base 31, causing the base 31 to rotate relative to the body 10. The liquid level detection mechanism 30 avoids the water storage tray 20 as the water storage tray 20 moves, so that the detection member 33 makes way for the installation and disassembly of the water storage tray 20, and the water storage tray 20 can be smoothly installed and disassembled. Of course, in other embodiments, the liquid level detection mechanism 30 can also move in the form of swinging, deformation, etc. This is not specifically limited by the present invention.

[0042] The rotation axis of the base 31 extends horizontally, meaning the axis of the rotating shaft 311 is horizontally oriented. The travel path of the water reservoir 20 is perpendicular to the axis of the rotating shaft 311, enabling the rotating shaft 311 to rotate clockwise or counterclockwise along the direction of movement of the water reservoir 20. With this arrangement, when the water reservoir 20 moves along the travel path, the base 31 rotates clockwise or counterclockwise along the travel path, smoothly making way for the water reservoir 20. Furthermore, when the base 31 drives the detecting member 33 to move, the detecting member 33 is less likely to collide strongly with the water reservoir 20, thereby protecting the liquid level detecting mechanism 30 and ensuring its service life.

[0043] The axis direction of the rotating shaft 311 is arranged along the horizontal direction, which means that the axis direction of the rotating shaft 311 is substantially consistent with the horizontal direction. For example, the axis direction of the rotating shaft 311 completely coincides with the horizontal direction, or the axis direction of the rotating shaft 311 is at a slight angle to the horizontal direction, wherein the slight angle ranges from 0° to 15°.

[0044] In this embodiment, a torsion spring 312 (combined with Figure 7 ), torsion spring 312 is in its natural position, and detection member 33 is located below base 31. Detection member 33 extends downward into cavity 26 of water reservoir 20, maintaining detection member 33 in the detection state. When water reservoir 20 is removed, detection member 33 also maintains this detection position, except that it does not extend into cavity 26 of water reservoir 20. The provision of torsion spring 312 allows base 31 to rotate downward and reset under the action of torsion spring 312, keeping detection member 33 stably in the detection state and ensuring accurate water level detection.

[0045] Reference Figure 4The base 31 is rotatably connected to the body 10. The base 31 can be connected to the body 10 directly or through other components. As an example, a rotating shaft 311 is connected to the base 31. The base 31 is connected to the body 10 via the rotating shaft 311. The axis of the rotating shaft 311 is the rotation axis of the base 31. The base 31 is provided with a mounting groove 313. The mounting groove 313 is located on the outer periphery of the rotating shaft 311. A torsion spring 312 is connected to the mounting groove 313. One end of the torsion spring 312 is engaged with the body 10, and the other end of the torsion spring 312 is engaged with the base 31.

[0046] For example, in this embodiment, a portion of the base 31 is positioned along the movement path, allowing the water reservoir 20 to cooperate with the base 31 during displacement. This prevents deformation and damage to the detection member 33 caused by direct contact with the water reservoir 20, thereby ensuring the service life of the liquid level detection mechanism 30. In alternative embodiments, a portion of the detection member 33 may also be positioned along the movement path. This is not specifically limited in the present invention.

[0047] Specifically, the upper edge of the abutting wall 22 is located within a preset height range when the base 31 is in the detection state; as the water storage tray 20 moves, the abutting wall 22 drives the base 31 to rotate, causing the detection member 33 to move into or out of the cavity 26. In other words, due to the height relationship between the upper edge of the abutting wall 22 and the base 31, the abutting wall 22 directly contacts the base 31 and indirectly drives the detection member 33 to move.

[0048] It's easy to understand that the liquid level detection mechanism 30 is separate from the water reservoir 20. When the water reservoir 20 is removed for cleaning, debris is unlikely to remain on the detection member 33, making it less likely that the liquid level detection mechanism 30 will mistakenly detect that the water is full. Furthermore, during the removal and installation of the water reservoir 20, the detection member 33 is displaced by the base 31, causing debris and wastewater to be vibrated and separated from the detection member 33. Therefore, this application improves the accuracy of water-full detection of the water reservoir 20 in a beverage dispenser, making it less likely that the water level detection mechanism 30 will mistakenly detect that the water is full.

[0049] Refer again Figure 3 In addition to the abutment wall 22, the water storage tray 20 also has a bottom wall 21, a front wall 23, and side walls 24. In this embodiment, the abutment wall 22 is a rear wall disposed opposite the front wall 23. Together, the bottom wall 21, the abutment wall 22, the front wall 23, and the side walls 24 form a cavity 26 within the water storage tray 20, which can store wastewater and coffee residue. As the water storage tray 20 moves along the movement path, the abutment wall 22 in the water storage tray 20 applies force to the base 31, which drives the detection member 33 to move into or out of the cavity 26.

[0050] In this embodiment, the abutting wall 22 of the water storage tray 20 extends upward from the bottom wall 21. Vertically, the upper edge of the abutting wall 22 extends within a predetermined height range h of the base 31. h is a natural number greater than 0, such as a value in the range of 1 cm to 10 cm. The specific value of h can be varied adaptively depending on the type of housing 10, and the numerical ranges presented here are merely illustrative. During installation and / or removal of the water storage tray 20, the abutting wall 22 of the water storage tray 20 abuts the base 31. The rotation of the base 31 causes the detection member 33 to swing, allowing the detection member 33 to smoothly yield to the water storage tray 20.

[0051] In an alternative embodiment, the abutting wall 22 may be a side wall in the left-right direction perpendicular to the front-to-back direction, i.e., the water storage tray 20 is installed and removed in the left-to-right direction. The abutting wall 22 may also be a wall panel located between the front wall 23 and the rear wall, i.e., the abutting wall 22 is independently disposed within the cavity 26. During the process of removing and installing the water storage tray 20, as long as the abutting wall 22 can exert force on the liquid level detection mechanism 30, causing the liquid level detection mechanism 30 to give way, the protection scope of the present invention is retained.

[0052] The lower end of the detection member 33 extends downward into the cavity 26 of the water reservoir 20, detecting whether the water reservoir 20 is full. Since the detection member 33 is not connected to the water reservoir 20, any coffee grounds remaining in the water reservoir 20 will not come into contact with the detection member 33. Therefore, false full detections are unlikely, resulting in more accurate detections. Furthermore, as the water reservoir 20 moves along its path, the detection member 33 makes way for the water reservoir 20, ensuring installation and removal of the water reservoir 20 and ensuring a smooth user experience.

[0053] When disassembling the water storage tray 20, refer to Figure 5 The front side of the abutting wall 22 abuts the rear side of the base 31, causing the base 31 to rotate under the force. The base 31 drives the detection member 33 to rotate toward the front side of the machine body 10, causing the detection member 33 to rotate toward the front side of the machine body 10. The water storage tray 20 continues to move toward the front side of the machine body 10, and the abutting wall 22 separates from the base 31. At this time, the detection member 33 moves out of the cavity 26, and the base 31 rotates downward and resets under the action of the torsion spring 312, so that the detection member 33 maintains the position in the detection state.

[0054] When installing the water storage tray 20, refer to Figure 6 The rear side of the abutting wall 22 abuts the front side of the base 31, causing the base 31 to rotate under the force. The base 31 drives the detection member 33 to rotate toward the rear side of the machine body 10, causing the detection member 33 to rotate toward the rear side of the machine body 10. The water storage tray 20 continues to move toward the rear side of the machine body 10, and the abutting wall 22 separates from the base 31. At this time, the detection member 33 moves into the receiving cavity 26, and the base 31 rotates downward and resets under the action of the torsion spring 312, so that the detection member 33 maintains the position in the detection state.

[0055] Therefore, in the present invention, the liquid level detection mechanism 30 can not only smoothly extend into the cavity 26 of the water storage tray 20 to detect water fullness, but also avoid the water storage tray 20 during the removal and installation process. The liquid level detection mechanism 30 has a simple structure and more accurate water fullness detection.

[0056] In an alternative embodiment, the base 31 can rotate and reset under the action of its own weight, or other elastic members can be provided between the base 31 and the body 10. When the base 31 is not subjected to force, as long as the base 31 can drive the detection member 33 to rotate to the position in the detection state, this embodiment is not specifically limited.

[0057] In an alternative embodiment, a drive element such as a motor may be connected to the body 10, and a touch switch may be provided between the water reservoir 20 and the body 10. The touch switch is electrically connected to the motor. When the water reservoir 20 is installed or removed, the water reservoir 20 triggers the touch switch, and the motor's movement drives the base 31 to rotate, causing the detection member 33 to move between a detection position within the cavity 26 and a position outside the cavity 26.

[0058] In this embodiment, a fixing base 11 is connected to the interior of the housing 10, and the base 31 is positioned above the water storage tray 20 via the fixing base 11. The fixing base 11 includes a mounting plate 111 and an extension plate 112. The mounting plate 111 is fixedly connected to the rear side of the housing 10, and the extension plate 112 is fixedly connected to the mounting plate 111. The extension plate 112 is an arc-shaped curved plate. The extension plate 112 has a first end 1121 fixedly connected to the mounting plate 111, and a second end 1122 extending from the rear side of the housing 10 toward the front side of the housing 10. The second end 1122 of the extension plate 112 extends above the water storage tray 20.

[0059] The mounting plate 111 is connected to the rear side of the machine body 10, which can reduce the volume of the extension plate 112 extending toward the front side of the machine body 10, does not occupy the installation space inside the coffee machine, makes the structure of the coffee machine more compact, and reduces production costs.

[0060] Reference Figure 3 The water reservoir 20 is provided with a water reservoir cover 25, which is provided with an escape opening 251. The escape opening 251 extends from the lower surface of the water reservoir cover 25 to the upper surface of the water reservoir cover 25. It is easy to understand that the lower surface of the water reservoir cover 25 is the surface facing the cavity 26, and the upper surface of the water reservoir cover 25 is the surface facing away from the cavity 26.

[0061] Specifically, the water reservoir cover 25 is located at the opening of the cavity 26, shielding the cavity 26. A portion of the cavity 26 located at the escape opening 251 is uncovered. The second end 1122 of the extension plate 112 is located above the escape opening 251, and the base 31 is pivotally disposed below the second end 1122, allowing the detection member 33 to extend into the cavity 26 or exit the cavity 26 through the escape opening 251.

[0062] The clearance opening 251 is sized to accommodate the liquid level detection mechanism 30. During the movement of the base 31 and the detection member 33, the clearance opening 251 can accommodate them. The clearance opening 251 is located on the water reservoir cover 25 near the abutment wall 22. In this embodiment, the clearance opening 251 is positioned near the rear side of the housing 10. During removal and installation of the water reservoir 20, only the abutment wall 22 of the water reservoir 20 contacts the base 31. The upper surface of the water reservoir cover 25 does not interfere with the base 31, facilitating the rotation of the base 31. When the water reservoir 20 is full, wastewater can be conveniently drained directly through the clearance opening 251 after the water reservoir 20 is removed.

[0063] At the same time, since the base 31 is arranged below the extension plate 112, the extension plate 112 can provide a shielding effect for the base 31, and there is no other structure around the detection part 33 to attach coffee powder. Therefore, coffee powder is not easy to remain on the detection part 33, and it is not easy to falsely detect that the water is full.

[0064] In one embodiment, referring to Figure 7 The second end 1122 of the extension plate 112 is fixedly connected to two ear plates 113, which are spaced apart and each of which has a mounting hole 114. The aforementioned rotating shafts 311 are fixed to both sides of the base 31, and the two rotating shafts 311 are respectively connected to the two mounting holes 114. Thus, the base 31 is rotatably connected between the two ear plates 113.

[0065] The ear plate 113 is provided with a first limiting hole 115, and the base 31 is provided with a second limiting hole 314. One end of the torsion spring 312 is inserted into the first limiting hole 115, and the other end of the torsion spring 312 is inserted into the second limiting hole 314. The arrangement of the mounting slot 313, the first limiting hole 115, and the second limiting hole 314 can limit the torsion spring 312, not only allowing the torsion spring 312 to be twisted and reset smoothly, but also facilitating its installation.

[0066] In this embodiment, referring to Figure 8The detection member 33 includes two conductive plates 331 fixed to the base 31. The conductive plates 331 are metal electrodes and are electrically connected to the electronic control system of the beverage dispenser via wires 334. The two conductive plates 331 can form an integral structure with the base 31, facilitating installation of the base 31.

[0067] When the wastewater in the water reservoir 20 gradually accumulates and submerges the bottoms of the two conductive plates 331, the wastewater causes the two conductive plates 331 to conduct electricity. This signal of connection between the two conductive plates 331 is transmitted to the coffee maker's electronic control system, which issues a command prompting the user to clear the wastewater from the water reservoir 20. If the two conductive plates 331 are conducting when coffee is not being brewed, the coffee maker will not function if the user does not clear the water reservoir 20. If the two conductive plates 331 are conducting during coffee brewing, the coffee maker will display a full water reminder after brewing, but will not function if the user does not clear the water reservoir 20.

[0068] In an optional embodiment, the detection component 33 may also be other components with a liquid level detection function, such as a liquid level detection sensor, etc., which is not specifically limited in this embodiment.

[0069] Reference Figure 8 and Figure 9 The base 31 includes a first shell 315 and a second shell 316 that fit together. The first shell 315 has two outwardly protruding connecting portions 3151. The rotating shaft 311, the mounting slot 313, and the second limiting hole 314 are all provided on the connecting portion 3151.

[0070] The first housing 315 and the second housing 316 together form two limiting grooves 317, and the two conductive sheets 331 are respectively retained within the two limiting grooves 317. The conductive sheet 331 has a snap-fit ​​portion 332 and a detection portion 333. The snap-fit ​​portion 332 is wider than the detection portion 333. The snap-fit ​​portion 332 snaps into place with the inner wall of the first housing 315, and the detection portion 333 extends from the opening of the limiting groove 317 to the outside of the limiting groove 317.

[0071] The first housing 315 and the second housing 316 can be joined together by providing a stepped annular groove 318 on the first housing 315 that matches the shape and size of the second housing 316, and engaging the first housing 315 and the second housing 316 via the stepped annular groove 318. A fastener 319 connects the first housing 315 and the second housing 316. A first connecting hole 320 is provided on the side of the first housing 315 facing the second housing 316, and a stepped groove 321 and a second connecting hole 322 are provided on the second housing 316, and the stepped groove 321 and the second connecting hole 322 are connected to each other.

[0072] The fastener 319 includes a rod and a head connected to each other. The rod passes through the second connecting hole 322 and is connected to the first connecting hole 320. The head abuts against the step groove 321. Matching thread structures can be set on the first connecting hole 320 and the rod.

[0073] The first housing 315 and the second housing 316 can be fixed together using a single fastener 319, resulting in a simple structure and easy assembly. Furthermore, in the assembled base 31, the fastener 319 is completely contained within the retaining groove 317, which can reduce the volume of the base 31 and make the coffee machine more compact.

[0074] The first housing 315 and the second housing 316 may also be joined in a manner such that: a snap-fitting slot 323 is defined on the first housing 315, and a protrusion 324 is provided on the second housing 316. The protrusion 324 protrudes toward one side of the snap-fitting slot 323. When the first housing 315 and the second housing 316 are assembled, the protrusion 324 engages with the snap-fitting slot 323, which not only facilitates precise alignment of the first housing 315 and the second housing 316, but also strengthens the connection between the first housing 315 and the second housing 316. A gap is left between the protrusion 324 and the snap-fitting slot 323. The wire 334 passes through the gap and connects to the control circuit in the housing 10, facilitating threading and connection of the wire 334.

[0075] The first shell 315 and the second shell 316 are both made of plastic or silicone. The plastic or silicone material wraps around the conductive sheet 331, protecting it. During installation and removal of the water reservoir 20, the water reservoir 20 comes into contact with the plastic or silicone material, not the conductive sheet 331, reducing the risk of damage to the sheet 331. In this embodiment, the base 31 is assembled from two pieces of plastic material, but the base 31 can also be formed integrally by injection molding.

[0076] In this embodiment, the first shell 315 and the second shell 316 have both of the above-mentioned combination modes. Of course, in other embodiments, the first shell 315 and the second shell 316 may also have only one of the combination modes.

[0077] In the embodiment of the present application, the liquid level detection mechanism 30 is disposed on the body of the coffee machine, thereby separating the liquid level detection mechanism 30 from the water storage tray 20, and further connecting the conductive sheet 331 to the base 31. The base 31 can protect the conductive sheet 331. During the process of removing and installing the water storage tray 20, the conductive sheet 331 will also move relative to the body 10 driven by the base 31, causing the residue and wastewater to be separated from the conductive sheet 331 by the vibration, further improving the detection accuracy and reducing false detection. Furthermore, because the conductive sheet 331 is not disposed on the water storage tray 20, when the water storage tray 20 is removed to pour out the wastewater, it will not collide with the conductive sheet 331, thereby ensuring the service life of the conductive sheet 331.

[0078] The beverage machine may include a brewer (not shown) and a waste pipe (not shown) disposed on the machine body 10. One end of the waste pipe is connected to the brewer, and the other end of the waste pipe is connected to the water reservoir 20. The waste pipe is used to drain waste water in the brewer into the water reservoir 20. When the beverage machine executes a cleaning command, the residual liquid in the brewer will flow into the water reservoir through the waste pipe. In a specific embodiment, the brewer includes a brewing cylinder, an upper piston and a lower piston respectively connected to the brewing cylinder. The brewing cylinder, the upper piston and the lower piston can jointly form a brewing chamber, that is, the brewing chamber is a space formed by the brewing cylinder, the upper piston and the lower piston. The brewing chamber is mainly used to fill coffee powder and extract it to form coffee liquid, which is then transported to the container. After the coffee extraction is completed, the coffee powder is moistened to form a coffee ground cake. The scraping process of the coffee ground cake may not be scraped clean, so coffee grounds will remain in the brewing chamber. In addition, during the coffee extraction process, coffee grounds are also likely to remain in the small holes of the filter screen on the surfaces of the upper and lower pistons. These coffee grounds will greatly affect the quality of the coffee. Therefore, the beverage machine needs to clean the brewing chamber regularly to discharge the coffee grounds. Specifically, the waste pipe is connected to the pressure relief pipe of the lower piston. After clean water is introduced into the brewing chamber for cleaning, the waste pipe can discharge the waste water in the brewing chamber to the water storage tray 20.

The above is only a preferred embodiment of the present invention, but the scope of implementation of the present invention is not limited to what is shown in the drawings. Any changes made in accordance with the concept of the present invention, or modifications to equivalent embodiments with equivalent changes, which do not exceed the spirit covered by the description and drawings, should be within the scope of protection of the present invention.
