Description

Technical Field

[0001] This utility model belongs to the technical field of washing machines, specifically relating to an integrated small drum washing machine with an embedded cabinet. Background Technology

[0002] With the improvement of living standards, modern home design increasingly pursues aesthetics and space utilization, and built-in appliances have become a mainstream trend due to their concealed installation and space-saving features. Although traditional small drum washing machines attempt to adapt to cabinet space by reducing their size, their structural design and functional implementation still have the following technical shortcomings:

[0003] 1. Redundant size and poor installation adaptability

[0004] Traditional small washing machines rely on independent metal or plastic shells to enclose internal components, making it difficult to compress the overall thickness and width. When embedded in a cabinet, an extra gap (usually greater than 5cm) must be left between the shell and the cabinet, disrupting the visual integrity of the cabinet. Moisture can easily seep into the seams of the shell, and over time, the internal circuit boards are prone to corrosion due to moisture. At the same time, condensation accumulates at the bottom of the shell and is difficult to drain, creating a risk of mold growth. In addition, the water inlet pipe, drain pipe, and power cord must be connected externally through openings in the cabinet. During installation, the interface positions need to be repeatedly calibrated, and disassembly and maintenance can easily damage the pipes or cabinet structure. Exposed pipes further exacerbate the visual clutter, failing to meet users' aesthetic needs for "invisible appliances."

[0005] 2. Insufficient ease of installation and maintenance.

[0006] Existing built-in washing machines rely on customized cabinets and complex piping openings. Precise alignment of water and electricity interfaces is required during installation, and disassembly and maintenance can easily damage the cabinet structure. Exposed pipes disrupt the visual integrity, and moisture can easily seep into the seams of the traditional outer casing. After long-term use, internal components become damp and age, leading to increased maintenance costs.

[0007] 3. In existing technologies, detergent foam easily overflows through the drum's venting channel, contaminating the interior of the cabinet. Current solutions rely on mechanical check valves or reducing detergent usage, lacking real-time monitoring and active defoaming mechanisms, leading to frequent sudden foam overflow problems. Utility Model Content

[0008] This utility model aims to at least partially solve one of the technical problems in related technologies. To this end, this utility model provides a built-in cabinet-type small drum washing machine that can improve the utilization of home space.

[0009] The technical solution is as follows:

[0010] A built-in cabinet-type mini drum washing machine includes a drum assembly, a water inlet system, a drainage system, and a control unit. The drum assembly includes an inner drum and an outer drum.

[0011] An open frame is adopted, which is directly embedded inside the cabinet. The bottom wall of the frame is fixedly connected to the bottom plate of the cabinet by fasteners, forming an integrated structure in which the cabinet serves as the outer shell of the washing machine.

[0012] The frame has a door frame on the front, and a machine door is installed on the door frame. When closed, the outer surface of the machine door is flush with the plane of the cabinet. The frame is fixedly connected to the cylinder assembly inside. The cylinder opening of the inner cylinder is sealed to the door frame through an elastic door seal. An exhaust channel is set at the top of the outer cylinder. An overflow detection unit is set on the exhaust channel. The overflow detection unit monitors the foam parameters in real time and transmits them to the control unit through an electrical signal. The control unit triggers the defoaming program according to the electrical signal.

[0013] The cylinder assembly is connected to the water inlet system and the drainage system respectively.

[0014] Furthermore, the bottom of the frame is fixedly connected to the bottom wall of the cabinet with bolts.

[0015] Furthermore, the overflow detection unit is an electrode sensing module, which includes an electrode sensing end and a first signal end. The electrode sensing end is located inside the exhaust channel, and the first signal end is located outside the exhaust channel. The electrode sensing end is used to sense electrical signals, and the first signal end is used to receive the electrical signals sensed by the electrode sensing end and transmit them to the control unit. The control unit receives the electrical signals and triggers the defoaming program.

[0016] Furthermore, the electrode sensing end is an electrode probe.

[0017] Furthermore, the overflow detection unit is a temperature sensing module, which includes a temperature sensing end and a second signal end, with the temperature sensing end located inside the exhaust channel.

[0018] Furthermore, the temperature sensing module is a temperature sensor.

[0019] Furthermore, the overflow detection unit includes a turbidity sensing end and a turbidity signal end, with the turbidity sensing end located outside the exhaust channel.

[0020] Furthermore, the turbidity sensing end is a turbidity sensor.

[0021] Furthermore, a rubber pad is provided at the bottom of the frame. The rubber pad is fitted into the bottom of the frame through a damping structure, and the rubber pad, washing machine, and cabinet are connected and fixed by fasteners.

[0022] Furthermore, a moisture-proof pad is provided around the inside and / or outside of the frame.

[0023] The technical solution includes at least the following technical effects:

[0024] 1. The open frame is directly embedded into the cabinet, eliminating redundant shells, resulting in a smaller size and achieving true "invisible installation".

[0025] 2. The frame and cylinder assembly are rigidly connected to meet the mechanical requirements of high-speed rotation of the drum and avoid the resonance risk of the suspension structure.

[0026] 3. A multi-modal overflow detection unit is adopted. The overflow detection unit monitors the foam parameters in real time and transmits them to the control unit through electrical signals. The control unit triggers the defoaming program according to the electrical signals and automatically triggers water dilution, pauses washing, or increases the number of rinsing times according to the detection signals, so as to achieve unattended operation.

[0027] 4. The bottom of the frame is fixed to the cabinet base plate with bolts and rubber pads. The damping structure absorbs vibration and reduces noise.

[0028] 5. A moisture-proof pad surrounds the frame to prevent condensation inside the cabinet and avoid circuit malfunctions due to moisture.

[0029] 6. The water and electricity interfaces are hidden in the back panel of the cabinet. They can be directly plugged in during installation without the need for drilling holes or external piping.

Detailed Implementation

[0037] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. In the following description, when referring to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this invention as detailed in the appended claims.

[0038] This utility model provides an integrated mini drum washing machine with a built-in cabinet, suitable for use in custom furniture such as bathroom cabinets and kitchen cabinets. Its open frame design allows for direct embedding into the cabinet, reducing size and cost. An overflow detection unit installed in the exhaust channel monitors foam in real time, triggering an intelligent defoaming program. This achieves a unified solution for smaller size, convenient installation, overflow prevention, foam prevention, and intelligent control. It aims to solve the problems of cumbersome installation and disassembly, limited size, overflow, and foam spillage associated with traditional small washing machines.

[0039] Taking a small drum washing machine installed in a bathroom cabinet as an example, as shown in the attached document... Figures 1-3 The image shows a built-in cabinet-type small drum washing machine, including a drum assembly 6, a water inlet system 7, a drainage system 5, an electrical system 8, and a control unit. The drum assembly 6 includes an inner drum 6-2 and an outer drum 6-1. In this embodiment, the washing machine is installed on the right side of the cabinet. In other embodiments, the washing machine can also be installed in the middle or left side of the cabinet. It is applicable to a single cabinet or multiple cabinets, and the layout position of the washing machine and the cabinet is not limited.

[0040] An open frame 3 is adopted, which is directly embedded inside the cabinet 9. The bottom wall of the frame 3 is fixedly connected to the bottom plate of the cabinet 9 by fasteners, forming an integrated structure where the cabinet serves as the outer shell of the washing machine. A door frame 2 is provided on the front side of the frame, and a machine door 1 is installed on the door frame 2. When closed, the outer surface of the machine door 1 is flush with the plane of the cabinet. The machine door is fixed to the door frame 2 by bolts 10. The inside of the frame 3 is fixedly connected to the drum assembly 6, and the opening of the inner drum 6-2 is sealed to the door frame 2 by a flexible door seal 4. All electrical components constitute the electrical system 8, which is connected to the control unit. All components are directly or indirectly connected to the frame 3.

[0041] The water and electricity interfaces are hidden in the back panel of cabinet 9, allowing for direct plug-in connection during installation without the need for drilling or external wiring. Simply install the entire unit inside cabinet 9, connect the water inlet pipe 7-1, drain pipe, and power supply, and secure it to cabinet 9. It's ready to use and requires no disassembly afterward. Once connected to water and electricity, the unit becomes an integral part of the cabinet. The unit can be recessed into various cabinets and connected to them. In this case, the cabinet becomes the washing machine's "outer shell." The shell-less design offers better cost-effectiveness, smaller size, and more convenient installation and storage; the "cabinet-electricity integration" aligns with current market trends; the door frame eliminates the hassle of installation and disassembly, providing a "one-time solution"; and the overall frame installation creates a more aesthetically pleasing and tidy home environment, free from cumbersome water and electrical pipes.

[0042] The outer cylinder 6-1 is provided with an exhaust channel 5-3 at the top. An overflow detection unit is provided on the exhaust channel 5-3. The overflow detection unit monitors the foam parameters in real time and transmits them to the control unit through an electrical signal. The control unit triggers the defoaming program according to the electrical signal. The cylinder assembly 6 is connected to the water inlet system 7 and the drainage system respectively.

[0043] A multi-modal overflow detection unit is employed. This unit monitors foam parameters in real time and transmits them to the control unit via electrical signals. The control unit triggers a defoaming program based on the electrical signals and automatically triggers water dilution, pauses washing, or increases the number of rinses based on the detection signals, enabling unattended operation. The overflow detection unit includes a sensing terminal 8-1 and a signal terminal 8-2.

[0044] A moisture-proof pad is installed around the inside and / or outside of the frame. The moisture-proof pad can be installed on the inside of the frame, on the outside of the frame, or on both the inside and outside of the frame simultaneously. The moisture-proof pad surrounds the frame to prevent condensation inside the cabinet and avoid electrical circuit malfunctions due to moisture.

[0045] The bottom of the frame is fixedly connected to the cabinet base plate with fasteners, adapting to the mechanical requirements of the high-speed rotation of the washing machine and avoiding the resonance risk of the suspension structure. In this embodiment, bolts are used as fasteners, and a rubber pad is set at the bottom of the frame. The rubber pad and the bottom of the frame are fitted together by a damping structure, and the rubber pad, washing machine, and cabinet are connected and fixed by bolts. The bottom of the frame is fixed to the cabinet base plate by bolts and rubber pads, and the damping structure absorbs vibration and reduces noise. In another embodiment, bolts and nuts can also be used for fixing. The pre-drilled holes penetrate the frame and the cabinet base plate, and the bolts are locked by nuts after penetration, providing high tensile strength and disassembly, suitable for standard wooden / metal cabinets and scenarios requiring frequent maintenance. Screws can also be directly screwed into the cabinet base plate (without pre-drilling holes or nuts), relying on the thread engagement for fixation. Installation is convenient, but the shear strength is slightly lower than that of bolts.

[0046] Example 1

[0047] The foam detection unit includes an electrode sensing module, which comprises an electrode sensing end and a first signal end. The electrode sensing end is located inside the exhaust channel 5-3, and the first signal end is located outside the exhaust channel 5-3. The first signal end is connected to the control unit via a cable. The electrode sensing end is used to sense foam and generate an electrical signal, and the first signal end is used to receive the electrical signal sensed by the electrode sensing end and transmit it to the control unit. The control unit receives the electrical signal and triggers the defoaming program. In this embodiment, the electrode sensing end is an electrode probe, and the control unit is a computer board. The electrode probe can transmit signals with the computer board.

[0048] The usage process is as follows:

[0049] When a drum washing machine washes, the detergent produces foam, which is then discharged outside the drum through the vent. Using the overflow detection unit in this embodiment, when the foam is discharged into the vent, the electrode sensing end detects an electrical signal. The first signal end transmits this signal to the control board, thereby stopping the washing machine's operation in time to prevent detergent foam from overflowing and causing a safety hazard. The principle is that the electrodes generate an electric current when they come into contact with water; if the electrode sensing end detects an electric current, it means there is water at the drain hole.

[0050] The computer board receives an electrical signal that triggers the defoaming program. The specific judgment process is as follows:

[0051] When a front-loading washing machine is washing normally without overflowing foam, no foam or water will enter the vent. At this time, the signals from the electrodes in the air are relatively stable. However, when detergent foam overflows and enters the vent, the foam or water will touch the electrodes, causing significant electrical signal fluctuations (e.g., increased capacitance, increased current, decreased resistance). The control board processes these signals and determines that there is foam overflow (meaning there is too much detergent and water needs to be added). In this case, the washing machine will enter the defoaming program, automatically triggering water dilution, pausing the wash cycle, or increasing the number of rinses based on the detected signal. This prevents damage to other parts of the washing machine due to foam overflow and reduces other safety risks.

[0052] Example 2

[0053] The overflow detection unit is a temperature sensing module, which includes a temperature sensing end and a second signal end. The temperature sensing end is located inside the exhaust channel 5-3, or it can be located near but within the exhaust channel 5-3. The temperature sensing end can sense the temperature. In this embodiment, the temperature sensing end is a temperature sensor, and the control unit is a computer board.

[0054] The usage process is as follows:

[0055] When a drum washing machine is used, the detergent produces foam, which is then discharged outside the drum through the vent. Using the overflow detection unit in this embodiment, a signal is detected when foam is discharged into the vent, allowing the washing machine to stop its operation promptly and preventing detergent foam from overflowing and posing a safety hazard.

[0056] The judgment process is as follows:

[0057] When a front-loading washing machine is washing normally without overflowing foam, no foam or water will enter the vent. At this time, the signal from the sensing module in the air is relatively stable. However, when detergent foam overflows and enters the vent, the sensing module detects a sudden temperature change due to the presence of foam or water, generating a signal. The control board processes this signal and determines that foam has overflowed. In this case, the washing machine will enter the defoaming program, automatically triggering water dilution, pausing the wash cycle, or increasing the number of rinses based on the detected signal. This prevents damage to other components of the washing machine due to foam overflow and reduces other safety risks.

[0058] Example 3

[0059] The overflow detection unit includes a turbidity sensing end and a third signal end. The turbidity sensing end is located inside the exhaust channel 5-3 and can sense turbidity. In this embodiment, the turbidity sensing end is a turbidity sensor, and the control unit is a computer board.

[0060] The usage process is as follows:

[0061] When a drum washing machine is used, the detergent produces foam, which is then discharged outside the drum through the vent. Using the overflow detection unit in this embodiment, a signal is detected when foam is discharged into the vent, allowing the washing machine to stop its operation promptly and preventing detergent foam from overflowing and posing a safety hazard.

[0062] The judgment process is as follows:

[0063] When a front-loading washing machine is washing normally without overflowing foam, no foam or water will enter the vent. At this time, the signal from the sensing module in the air is relatively stable. However, when detergent foam overflows and enters the vent, the sensing module detects a sudden increase in turbidity due to the presence of foam or water, generating a signal. The control board processes this signal and determines that foam has overflowed. At this point, the washing machine will enter the defoaming program, automatically triggering water dilution, pausing the wash cycle, or increasing the number of rinses based on the detection signal. This prevents damage to other components of the washing machine due to foam overflow and reduces other safety risks.
