Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology, and in particular to a water supply component and electrical equipment for an electrical device with a water tank. Background Technology

[0002] Currently, water level detection structures on the market use proximity switches with floats or contact detection methods. These methods not only pollute the water but also accumulate scale and dust over time, affecting detection accuracy. Alternatively, the water level detection structure is directly mounted on the water tank, meaning it moves with the tank when it is disassembled or moved, impacting its lifespan. Furthermore, the connected leads make tank disassembly and movement inconvenient for users. For example, Chinese patent CN102768057A discloses a water level switch and water level signal detection device, including a fixed magnetic element, a magnet corresponding to the magnetic element, a microprocessor unit electrically connected to the magnetic element, and a float. The magnet and float are linked and integrated, indicating that this float-based water level switch structure pollutes the water. Utility Model Content

[0003] In view of the above-mentioned technical problems existing in the prior art, this utility model provides a water supply component and electrical equipment with a water tank, realizing a solution for non-contact detection of the water level in the water tank by the water level detection plate, which can not only avoid contamination of the water in the water tank, but also ensure detection accuracy.

[0004] This application provides a water supply component for an electrical device with a water tank, comprising:

[0005] The body includes a vertically arranged mounting plate, the mounting plate having a first wall and a second wall disposed opposite to each other, the first wall facing the interior of the body and the second wall facing the exterior of the body;

[0006] A water tank, the tank wall of which is attached to the second wall surface;

[0007] A water level detection component includes a water level detection plate. The water level detection plate includes a plate body and multiple water level sensors disposed on the plate body. The plate body is attached to a first wall surface. The multiple water level sensors are arranged at intervals along the height direction of the water tank, and the multiple water level sensors are used to cooperate in detecting the water level information in the water tank. This achieves a non-contact water level detection solution for the water level detection plate, which not only avoids contamination of the water in the tank but also ensures detection accuracy.

[0008] In some embodiments, the plate body is a single unit, and all the plurality of water level sensors are disposed on the plate body; or, the plate body is configured as multiple sub-plate bodies, with each sub-plate body corresponding to one of the water level sensors. In this way, multiple water level sensors can be stably mounted on the plate body.

[0009] In some embodiments, the water supply assembly further includes a main control board disposed within the machine body. The main control board has a main control module electrically connected to the plurality of water level sensors. The main control module is used to receive the water level information detected by the plurality of water level sensors and to generate a prompt message indicating the water level in the water tank. Thus, the main control module can generate a prompt message that can be sent outwards when the water level information is detected by the water level sensors, promptly reminding the user of the current remaining water level in the water tank.

[0010] In some embodiments, the water level detection component further includes a water level detection module electrically connected to the main control module, and the main control module is electrically connected to the plurality of water level sensors through the water level detection module. Thus, the main control module can control the plurality of water level sensors through the water level detection module.

[0011] In some embodiments, the water level sensor is one of the following: a capacitive sensor, an inductive sensor, and a composite sensor. The above-mentioned water level sensor enables accurate detection of the water level in the water tank.

[0012] In some embodiments, the water supply assembly further includes a temperature detection component and a heating component. The inlet of the heating component is connected to the water tank for heating water from the tank. The temperature detection component is electrically connected to the main control module and is located at the outlet of the heating component for detecting the temperature of the water heated by the heating component. Thus, the temperature detection component can accurately detect the temperature of the water discharged from the heating component, preventing situations where the water discharged from the heating component is too hot or too cold.

[0013] In some embodiments, the water supply assembly further includes a power board disposed within the machine body. The power board is electrically connected to the main control board and is used to supply power to the main control board. Thus, the power board can provide stable power to the main control board, ensuring its stable operation.

[0014] In some embodiments, the water supply assembly further includes a display module electrically connected to the main control module. The main control module is also used to send the water level information to the display module, and the display module is used at least to display the water level information. Thus, the water level information can be displayed through the display module, allowing users to intuitively obtain the remaining water volume in the water tank, facilitating user operation.

[0015] In some embodiments, the sum of the thickness of the mounting plate and the thickness of the tank wall attached to the second wall surface ranges from 3mm to 7mm, so as to ensure that the water level detection component can accurately detect the water level in the tank through the mounting plate and the tank wall.

[0016] This application also provides an electrical device, including a water supply component of the electrical device with a water tank as described in any of the above embodiments. This achieves a non-contact method for detecting the water level in the water tank using a water level detection plate, which not only avoids contaminating the water in the tank but also ensures detection accuracy.

[0017] Compared with the prior art, the beneficial effects of this utility model embodiment are as follows: This utility model, through the water level detection plate attached to the first wall and multiple water level sensors installed on the plate, can accurately detect the water level of the water tank attached to the second wall. There is no direct connection between the water level detection plate and the water tank; they are respectively installed on opposite walls of the mounting plate of the machine body, realizing a non-contact water level detection solution. This not only avoids contamination of the water in the tank but also ensures detection accuracy. Furthermore, since there is no direct connection between the water level detection plate and the water tank, it is convenient to remove the water tank from the machine body or to allow the water tank to move relative to the machine body, increasing user convenience and ease of filling and removing water from the tank. It also avoids the problem of the water level detection plate's lifespan being affected by the movement of the water tank. Attached Figure Description

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] This application provides a water supply component for an electrical device with a water tank. For example... Figures 1 to 3 As shown, the water supply assembly includes a body 1, a water tank 2, and a water level detection assembly 3. The body 1 includes a vertically mounted mounting plate 11, which has a first wall and a second wall facing each other. The first wall faces inwards from the body 1, and the second wall faces outwards from the body 1. The walls of the water tank 2 are attached to the second wall. The water level detection assembly 3 includes a water level detection plate 31, which includes a plate body 32 and multiple water level sensors 33 mounted on the plate body 32. The plate body 32 is attached to the first wall, and the multiple water level sensors 33 are arranged at intervals along the height of the water tank 2, and are used to detect the water level information inside the water tank 2.

[0029] The aforementioned body 1 has an internal accommodating cavity. The water level detection component 3 can be integrally disposed within the accommodating cavity. The water level detection component 3 can be detachably connected to the mounting plate 11 or fixedly mounted on the mounting plate 11. This application does not specifically limit this. In addition to the mounting plate 11, the aforementioned body 1 may also include multiple sequentially connected plate-like structures to form the aforementioned accommodating cavity.

[0030] The aforementioned mounting plate 11 can be understood as being positioned perpendicular to the horizontal direction. Figure 1 The mounting plate 11 shown is vertically installed.

[0031] The water tank 2 described above can be detachably connected to the mounting plate 11, or it can be fixedly installed on the mounting plate 11. This application does not make any specific limitation on this.

[0032] The aforementioned multiple water level sensors 33 do not need to be in direct contact with water. Water is conductive, and when the water level comes into contact with the detection surface of the water level sensor 33, the water level sensor 33 will sense the water level and generate corresponding parameter changes. For example, when the water level sensor 33 is a capacitive sensor, when the water level comes into contact with the surface of the capacitive sensor, the capacitance value of the capacitive sensor will change, thereby realizing the sensing of the water level.

[0033] The plate 32, the mounting plate 11, and the tank wall of the water tank 2 are tightly fitted together in sequence to ensure that the water level sensor 33 can accurately detect the water level.

[0034] The arrangement of multiple water level sensors 33 at intervals along the height of the water tank 2 ensures that the water level sensor 33 corresponding to the water surface in the water tank 2 can detect the water level. The interval between the multiple water level sensors 33 can be minimized as much as possible while ensuring that the water level sensors 33 can work normally, so as to ensure accurate detection of the water level.

[0035] The aforementioned plate 32 can be a circuit board, and multiple water level sensors 33 can be electrically connected to the circuit board.

[0036] This invention, through the water level detection plate 31 body 32 attached to the first wall and multiple water level sensors 33 mounted on the body 32, can accurately detect the water level of the water tank 2 attached to the second wall. The water level detection plate 31 and the water tank 2 are not directly connected; they are respectively mounted on opposite walls of the mounting plate 11 of the body 1. This achieves a non-contact water level detection solution for the water level detection plate 31, which not only avoids contamination of the water in the water tank 2 but also ensures detection accuracy. Furthermore, since the water level detection plate 31 and the water tank 2 are not directly connected, it is convenient to remove the water tank 2 from the body 1 or to allow the water tank 2 to move relative to the body 1, increasing user convenience and avoiding the problem of the water level detection plate 31's lifespan being affected by the movement of the water tank 2.

[0037] In some embodiments, such as Figures 3 to 5 As shown, there is one plate 32, and multiple water level sensors 33 are all installed on the plate 32; or, the plate 32 is configured as multiple sub-plates, and the sub-plates are configured in a one-to-one correspondence with the water level sensors 33.

[0038] In this way, multiple water level sensors 33 can be stably installed through the plate 32.

[0039] like Figure 3 and Figure 5 As shown, Figure 3 and Figure 5 The plate 32 shown is one, and multiple water level sensors 33 are all disposed on the plate 32. The plate 32 can be a circuit board, and multiple water level sensors 33 are disposed on one circuit board.

[0040] like Figure 4 As shown, Figure 4 The plate 32 shown includes multiple sub-plates, each corresponding to a water level sensor 33. The sub-plates can be circuit boards, meaning the plate 32 includes multiple circuit boards, each corresponding to a water level sensor 33.

[0041] In some embodiments, such as Figure 1 and Figure 6 As shown, the water supply assembly also includes a main control board 4 located inside the body 1. The main control board 4 is equipped with a main control module 41. The main control module 41 is electrically connected to multiple water level sensors 33 respectively. The main control module 41 is used to receive water level information detected by multiple water level sensors 33 and generate prompt information indicating the water level in the water tank 2.

[0042] In this way, the main control module 41 on the main control board 4 can generate a prompt message that can be sent out when the water level information is detected by the water level sensor 33, so as to remind the user of the current remaining water in the water tank 2.

[0043] The main control module 41 can generate prompts in a timely manner when the water level information indicates that the current remaining water in the water tank 2 is too low or too high, so as to remind the user that the current remaining water in the water tank 2 is insufficient and needs to be added, or that the remaining water is excessive and needs to be stopped.

[0044] It should be noted that the main control board 4 can be constructed using electronic components such as timers, comparators, registers, and digital logic circuits, or it can be implemented using processor chips such as microcontrollers, microprocessors, programmable logic controllers (PLCs), digital signal processors (DSPs), field-programmable gate arrays (FPGAs), programmable logic arrays (PLAs), and application-specific integrated circuits (ASICs) and their peripheral circuits.

[0045] like Figure 6 As shown, the water supply component also includes a button module 8 electrically connected to the main control module 41. Users can control the operation of the water supply component by triggering the button module 8, such as controlling the opening and closing of the water level detection component 3 of the water supply component.

[0046] In some embodiments, such as Figure 6As shown, the water level detection component 3 also includes a water level detection module 34 electrically connected to the main control module 41. The main control module 41 is electrically connected to multiple water level sensors 33 through the water level detection module 34.

[0047] Thus, the main control module 41 can control multiple water level sensors 33 through the water level detection module 34.

[0048] The aforementioned multiple water level sensors 33 can generate capacitance information after detection. The water level detection module 34 can receive this capacitance information and perform at least one of the following processing methods on the capacitance information: filtering, analysis, comparison, and judgment, to generate a processing result. The main control module 41 can receive the processing result and generate a prompt message indicating the water level in the water tank 2 based on the processing result.

[0049] In some other embodiments, the water level detection component 3 may not include the water level detection module 34, and the main control module 41 may be directly electrically connected to multiple water level sensors 33, and the main control module 41 may directly receive the capacitance information generated by the water level sensors 33.

[0050] In some embodiments, the water level sensor 33 is one of the following: a capacitive sensor, an inductive sensor, and a composite sensor. The water level sensor 33 described above can achieve accurate detection of the water level in the water tank 2. The composite sensor, by integrating two or more sensor units with different functions, achieves accurate detection of the water level in the water tank 2.

[0051] In some embodiments, such as Figure 6 As shown, the water supply assembly also includes a temperature detection component 5 and a heating component (not shown in the figure). The inlet end of the heating component is connected to the water tank 2 and is used to heat the water from the water tank 2. The temperature detection component 5 is electrically connected to the main control module 41 and is located at the outlet end of the heating component to detect the temperature information of the water heated by the heating component.

[0052] In this way, the temperature of the water discharged from the heating element can be accurately detected by the temperature detection component 5, avoiding the situation where the water discharged from the heating element is too cold or too hot.

[0053] The water inlet of the heating component can be directly connected to the water tank 2, or it can be connected to the water tank 2 through a water pump. This application does not specify the connection method between the water inlet of the heating component and the water tank 2.

[0054] The main control module 41 can receive temperature information and control the heating component based on the temperature information. If the temperature is insufficient, the heating power of the heating component will be increased; if the temperature is too high, the heating power of the heating component will be reduced.

[0055] In some embodiments, such as Figure 1 and Figure 6 As shown, the water supply assembly also includes a power board 6 located inside the body 1. The power board 6 is electrically connected to the main control board 4, and the power board 6 is used to supply power to the main control board 4.

[0056] In this way, the power supply board 6 can provide stable power to the main control board 4, ensuring the stable operation of the main control board 4.

[0057] In some embodiments, such as Figure 6 As shown, the water supply component also includes a display module 7, which is electrically connected to the main control module 41. The main control module 41 is also used to send water level information to the display module 7, and the display module 7 is used to display water level information at least.

[0058] In this way, the water level information can be displayed through the display module 7, allowing users to intuitively obtain the remaining water in the water tank 2, which is convenient for users.

[0059] The aforementioned display module 7 can also display the operating status of electrical equipment using water supply components, such as whether it is working or not.

[0060] The aforementioned display module 7, water level detection module 34, and button module 8 can be located on the main control board 4, or they can be set independently of the main control board 4. This application does not make any specific limitations on this.

[0061] In some embodiments, the sum of the thickness of the mounting plate 11 and the thickness of the tank wall of the water tank 2 attached to the second wall is in the range of 3mm to 7mm, so as to ensure that the water level detection component 3 can accurately detect the water level in the water tank 2 through the mounting plate 11 and the tank wall of the water tank 2.

[0062] Preferably, the sum of the thickness of the mounting plate 11 and the thickness of the tank wall of the water tank 2 attached to the second wall is 3mm, 3.5mm, 4mm, 4.5mm, 5mm, 6mm or 7mm. Of course, the sum of the two thicknesses is not limited to this thickness, as long as it can ensure that the water level detection component 3 can accurately detect the water level in the water tank 2.

[0063] This application also provides an electrical device. The electrical device includes the water supply component of the electrical device with a water tank according to any of the above embodiments.

[0064] This invention, through the water level detection plate 31 body 32 attached to the first wall and multiple water level sensors 33 mounted on the body 32, can accurately detect the water level of the water tank 2 attached to the second wall. The water level detection plate 31 and the water tank 2 are not directly connected; they are respectively mounted on opposite walls of the mounting plate 11 of the body 1. This achieves a non-contact water level detection solution for the water level detection plate 31, which not only avoids contamination of the water in the water tank 2 but also ensures detection accuracy. Furthermore, since the water level detection plate 31 and the water tank 2 are not directly connected, it is convenient to remove the water tank 2 from the body 1 or to allow the water tank 2 to move relative to the body 1, increasing user convenience and avoiding the problem of the water level detection plate 31's lifespan being affected by the movement of the water tank 2.

[0065] The aforementioned electrical equipment can be beverage preparation equipment, such as coffee machines.

[0066] The above embodiments are merely exemplary embodiments of this utility model and are not intended to limit this utility model. Those skilled in the art can make various modifications or equivalent substitutions to this utility model within its substance and protection scope, and such modifications or equivalent substitutions should also be considered to fall within the protection scope of this utility model.
