Description

Technical Field

[0001] This invention relates to the field of home appliance technology, and in particular to a drum washing machine with a function to detect missing packaging bolts. Background Technology

[0002] As people's purchasing power increases, the frequency of replacing home appliances is accelerating. During transportation, appliances inevitably experience bumps and vibrations, which can easily damage them. For example, the drum of a front-loading washing machine is typically suspended inside the machine's casing and can move relative to it. If the washing machine experiences excessive vibration during transport, the drum can easily collide with the casing due to shaking, causing damage to both. To address this issue, packaging bolts are usually pre-installed between the drum and the casing before the washing machine leaves the factory. These bolts secure the drum inside the casing, fixing their relative position during transport and preventing damage.

[0003] However, some users install the washing machine themselves after receiving it, which may result in forgetting to remove the packaging bolts, affecting the normal use of the washing machine and shortening its lifespan. To remind users to remove the packaging bolts before use, existing technologies typically employ the following two methods:

[0004] (1) The installation instructions are placed in conspicuous places such as countertops, but some customers still do not carefully check the installation instructions, resulting in the failure to remove the packaging bolts.

[0005] (2) Install a ring-shaped sleeve on the packaging bolt, pass the power cord through the ring-shaped sleeve and fix it to the packaging bolt. Ideally, the user must remove the packaging bolt to remove the power cord. With this method, if the ring-shaped sleeve is made of plastic, some users will cut the ring-shaped sleeve and still not need to remove the packaging bolt; if the ring-shaped sleeve is made of metal, there is a safety risk of breaking the power cord.

[0006] Therefore, there is an urgent need to develop a drum washing machine with a function to detect missing packaging bolts in order to solve the above problems. Summary of the Invention

[0007] Based on the above, the purpose of this invention is to provide a drum washing machine with a function of detecting missing packaging bolts, which can remind users of missing packaging bolts, has a simple structure, low manufacturing cost, and high safety in use.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A drum washing machine with a function for detecting missing packaging bolts includes a cabinet and a drum, the drum being disposed inside the cabinet. Packaging bolts can be sequentially inserted through the cabinet and the drum to fix the cabinet and the drum. The drum washing machine also includes:

[0010] The detection component includes a transmitter and a receiver, both of which are mounted on the housing. The receiver can receive the signal transmitted by the transmitter. When the packaging bolts are not removed, the signal transmitted by the transmitter can be blocked by the packaging bolts.

[0011] An alarm component is configured to trigger an alarm when the receiver fails to receive a signal from the transmitter.

[0012] The display screen is electrically connected to the detection component and is configured to display the setting position and removal steps of the packaging bolts when the receiver cannot receive the signal from the transmitter.

[0013] As a preferred embodiment of a drum washing machine with a function for detecting missing packaging bolts, the cabinet is provided with a first connection hole, the drum is provided with a second connection hole, at least one of the hole walls of the first connection hole and the second connection hole is provided with a reverse electromagnet, the reverse electromagnet can be electrically connected to the power supply circuit of the drum washing machine, and the packaging bolts are sequentially inserted into the first connection hole and the second connection hole.

[0014] As a preferred embodiment of a drum washing machine with a function to detect missing packaging bolts, the axis of the first connecting hole slopes downwards from the outside to the inside, and the axis of the second connecting hole is collinear with the axis of the first connecting hole.

[0015] In a preferred embodiment of a drum washing machine with a function to detect missing packaging bolts, a first buffer element is provided on the wall of the first connecting hole; and / or

[0016] A second buffer is provided on the wall of the second connecting hole.

[0017] As a preferred embodiment of a drum washing machine with a function to detect missing packaging bolts, both the first and second buffer components are made of rubber.

[0018] As a preferred embodiment of a drum washing machine with a function to detect missing packaging bolts, a collection groove is provided on the outer wall of the casing, and the opening of the collection groove is located directly below the packaging bolt.

[0019] As a preferred embodiment of a drum washing machine with a function to detect missing packaging bolts, the collection tank is detachably connected to the casing.

[0020] As a preferred embodiment of a drum washing machine with a function to detect missing packaging bolts, the inner wall of the casing is provided with a first receiving slot for accommodating the transmitter and a second receiving slot for accommodating the receiver.

[0021] As a preferred embodiment of a drum washing machine with a function to detect missing packaging bolts, both the transmitter and the receiver can be detachably connected to the housing.

[0022] As a preferred embodiment of a drum washing machine with a function for detecting missing packaging bolts, the first receiving tank has a plurality of first slots spaced apart circumferentially on its wall, and the outer wall of the transmitting end has a plurality of first protrusions spaced apart circumferentially, the plurality of first protrusions being able to be engaged one-to-one with the plurality of first slots; and / or

Through the cooperation of the detection component and the alarm component, if the user forgets to remove the packaging bolt during the installation of the drum washing machine, the bolt will block the signal transmitted by the transmitter when the user starts the machine, preventing the receiver from receiving the signal. At this time, the alarm component will sound an alarm to remind the user that the packaging bolt is missing, allowing the user to remove it in time and avoid affecting the normal use of the drum washing machine. In addition, the display screen will show the location of the packaging bolt and the removal steps to help the user find the bolt in time and guide the user to remove it in time to avoid affecting the normal use of the drum washing machine. This drum washing machine has a simple structure, low manufacturing cost, high safety, and can extend the service life of the drum washing machine, resulting in a better user experience.

[0035] 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 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, and not all of the structures.

[0036] In the description of this invention, 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 invention based on the specific circumstances.

[0037] 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.

[0038] In the description of this embodiment, the terms "upper," "lower," "left," and "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 the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0039] like Figures 1-3 As shown, this embodiment provides a drum washing machine with a missing packaging bolt detection function. The drum washing machine includes a cabinet 1 and a drum 2 disposed inside the cabinet 1. The drum 2 includes an inner drum and an outer drum, with the inner drum disposed inside the outer drum. During operation, the energy generated by the eccentricity of the inner drum can be eliminated by the vibration of the outer drum. Under normal circumstances, the cabinet 1 does not vibrate or only vibrates slightly. Before the drum washing machine leaves the factory, to avoid excessive vibration during transportation that could cause collision between the drum 2 and the cabinet 1, resulting in damage, the prior art typically uses packaging bolts 10 to connect the drum 2 and the cabinet 1, ensuring that their vibrations are identical and thus preventing relative displacement and damage. When users install the drum washing machine, they need to remove the packaging bolts 10. However, some users often forget to remove the packaging bolts 10, which causes the eccentricity of the inner drum to be transmitted to the cabinet 1 through the outer drum when the user starts the drum washing machine. This causes the entire drum washing machine to shift on the ground, affecting the performance and resulting in a poor user experience.

[0040] To address the aforementioned issues, the drum washing machine with a missing packaging bolt detection function provided in this embodiment further includes a detection component 3 and an alarm component. The detection component 3 includes a transmitter 31 and a receiver 32, both mounted on the casing 1. The receiver 32 can receive signals transmitted by the transmitter 31. When the packaging bolt 10 is not removed, the signal transmitted by the transmitter 31 can be blocked by the packaging bolt 10. The alarm component is configured to sound an alarm when the receiver 32 cannot receive the signal from the transmitter 31. Optionally, the detection component 3 is an infrared photoelectric switch, which is readily available and offers high detection accuracy.

[0041] The drum washing machine with missing packaging bolt detection function provided in this embodiment, through the cooperation between the detection component 3 and the alarm component, will detect if the user forgets to remove the packaging bolt 10 during installation. When the user starts the drum washing machine, the packaging bolt 10 will block the signal emitted by the transmitter 31, preventing the receiver 32 from receiving the signal. At this time, the alarm component will sound an alarm to remind the user that the packaging bolt 10 on the drum washing machine has been missed, allowing the user to remove it in time and avoid affecting the normal use of the drum washing machine. This drum washing machine has a simple structure, low manufacturing cost, high safety in use, and can extend the service life of the drum washing machine, resulting in a better user experience.

[0042] Furthermore, the alarm component includes a buzzer and / or an indicator light. Specifically, the alarm component is electrically connected to the controller of the drum washing machine. When the receiver 32 cannot receive the signal from the transmitter 31, it indicates that the signal emitted by the transmitter 31 is blocked by the packaging bolt 10, meaning that the user forgot to remove the packaging bolt 10 during installation. The controller then controls the buzzer to sound an alarm or controls the indicator light to illuminate to remind the user and simultaneously pauses the operation of the drum washing machine to prevent damage during operation due to the failure to remove the packaging bolt 10.

[0043] Preferably, the alarm component may further include a voice prompt, which is configured to issue a voice alert when the receiver 32 fails to receive a signal from the transmitter 31. When the buzzer sounds an alarm or the indicator light illuminates, the user may not be able to determine what kind of malfunction has occurred in the drum washing machine. By setting up the voice prompt, the voice prompt can inform the user of the malfunction of the drum washing machine through voice reminders, so as to remove the packaging bolt 10 in time.

[0044] Furthermore, the drum washing machine also includes a display screen configured to show the location and removal steps of the packaging bolt 10 when the receiver 32 cannot receive the signal from the transmitter 31. Specifically, both the display screen and the detection component 3 are electrically connected to the controller of the drum washing machine. When the receiver 32 cannot receive the signal from the transmitter 31, it indicates that the signal emitted by the transmitter 31 is blocked by the packaging bolt 10, meaning that the user forgot to remove the packaging bolt 10 during installation. The controller will control the display screen to show the location and removal steps of the packaging bolt 10, so that the user can find the packaging bolt 10 in time and be guided to remove it in time to avoid affecting the normal use of the drum washing machine.

[0045] Furthermore, the housing 1 is provided with a first connecting hole 11, and the drum 2 is provided with a second connecting hole. At least one of the walls of the first connecting hole 11 and the second connecting hole is provided with a reverse electromagnet. The reverse electromagnet can be electrically connected to the power supply circuit of the drum washing machine. The packaging bolts 10 are sequentially inserted into the first connecting hole 11 and the second connecting hole. It should be noted that the reverse electromagnet is an electromagnet that does not generate an attractive force when energized, but generates an attractive force when de-energized. The reverse electromagnet is existing technology, and the specific structure of the reverse electromagnet will not be described in detail in this embodiment.

[0046] By providing a reverse electromagnet in at least one of the holes in the first connecting hole 11 and the second connecting hole, when the drum washing machine is being transported, the reverse electromagnet is de-energized and can generate an attractive force to firmly hold the packaging bolt 10, preventing the relative position of the drum 2 and the housing 1 from shifting. When the user installs the drum washing machine but forgets to remove the packaging bolt 10, the alarm component will provide a prompt that the packaging bolt 10 has been forgotten when the user powers on the drum washing machine for the first time. The display screen will show the setting position of the packaging bolt 10. At this time, since the reverse electromagnet is energized and does not generate an attractive force, the user only needs to pull gently to remove the packaging bolt 10 without the need for any external tools, which is simple, convenient and quick.

[0047] Optionally, the axis of the first connecting hole 11 slopes downwards from the outside to the inside, and the axis of the second connecting hole is collinear with the axis of the first connecting hole 11. With this configuration, the packaging bolt 10 can be inserted downwards into the box 1 and the cylinder 2. The inclined walls of the first and second connecting holes provide support for the packaging bolt 10. Even when the reverse electromagnet is energized, the packaging bolt 10 will not fall from the first and second connecting holes into any corner of the room, preventing users from being injured by the packaging bolt 10 without their knowledge.

[0048] Furthermore, a first buffer is provided on the wall of the first connecting hole 11; and / or a second buffer is provided on the wall of the second connecting hole. When the reverse electromagnet is energized, the attraction force disappears. When the user is looking for the location of the packaging bolt 10, the drum washing machine may be moved. At this time, the packaging bolt 10 will rub against the first connecting hole 11 and the second connecting hole. By providing the first buffer and the second buffer, the packaging bolt 10 can be prevented from wearing down the walls of the first connecting hole 11 and the second connecting hole, thus maintaining the structural integrity of the cabinet 1.

[0049] Optionally, both the first and second buffer components are made of rubber. Rubber has good cushioning performance, is readily available, and has low manufacturing costs. Furthermore, rubber also has a certain degree of elastic deformation, which allows the packaging bolts 10 to maintain a good connection with the box body 1 and the cylinder body 2.

[0050] Furthermore, a collection groove is provided on the outer wall of the casing 1, with its opening located directly below the packaging bolt 10. By providing the collection groove, when the user moves the drum washing machine, causing significant positional movement that results in the packaging bolt 10 detaching from the first connecting hole 11 and the second connecting hole, the collection groove can catch the packaging bolt 10, preventing it from falling into other corners of the room. Optionally, the collection groove is detachably connected to the casing 1. After the packaging bolt 10 is removed, the user can also remove the collection groove from the casing 1 to reduce the size of the drum washing machine and facilitate its placement. The detachable connection method between the collection groove and the casing 1 is not limited in this embodiment; the collection groove can be snapped onto the casing 1 or fixed to the casing 1 using mounting bolts.

[0051] It is understandable that the drum 2 will vibrate when the user uses the washing machine. Therefore, there is a certain gap between the drum 2 and the cabinet 1 to provide sufficient vibration space for the drum 2 and prevent the drum 2 from causing the cabinet 1 to vibrate synchronously. In this embodiment, the detection component 3 is located in the gap between the drum 2 and the cabinet 1. To avoid interference between the drum 2 and the detection component 3 when vibrating, a first receiving groove for accommodating the transmitter 31 and a second receiving groove for accommodating the receiver 32 are provided on the inner wall of the cabinet 1. By providing the first and second receiving grooves, the transmitter 31 and the receiver 32 can be accommodated respectively, thereby avoiding interference between the drum 2 and the detection component 3 when vibrating and improving the utilization rate of the gap between the drum 2 and the cabinet 1.

[0052] Since the signal emitted by the transmitter 31 can always be received by the receiver 32 even if the user removes the packaging bolts 10, the detection component 3 is only used the first time the drum washing machine is started. In this embodiment, both the transmitter 31 and the receiver 32 are detachably connected to the housing 1. This arrangement allows for the removal of the transmitter 31 and receiver 32 after the user removes the packaging bolts 10, reducing the weight of the drum washing machine and making it easier for the user to move it to any location. Furthermore, it allows for the reuse of the transmitter 31 and receiver 32.

[0053] Specifically, the first receiving groove has multiple first slots spaced apart along its circumference on its groove wall, and the transmitter 31 has multiple first protrusions spaced apart along its circumference on its outer wall. The multiple first protrusions can be engaged in the multiple first slots one by one, thereby realizing the detachable connection between the transmitter 31 and the housing 1.

[0054] Optionally, to facilitate the installation of the transmitter 31, the first protrusion is made of an elastic material. When assembling the transmitter 31 and the housing 1, the operator can press the transmitter 31 into the first receiving groove by deforming the first protrusion. When multiple first protrusions are aligned with their corresponding first slots, the first protrusions are engaged in the corresponding first slots under the action of elastic restoring force, thus completing the installation.

[0055] Similarly, the second receiving groove has multiple second slots spaced apart circumferentially on its wall, and the receiver 32 has multiple second protrusions spaced apart circumferentially on its outer wall. These protrusions can be engaged one-to-one with the second slots, thus achieving a detachable connection between the receiver 32 and the housing 1. Optionally, to facilitate the installation of the receiver 32, the second protrusions are made of an elastic material. The installation process of the receiver 32 and the housing 1 is the same as the installation process of the transmitter 31 and the housing 1, and will not be described further in this embodiment.

[0056] Furthermore, a first through hole is provided on the outer wall of the housing 1, which is directly opposite to and connected to the first receiving groove; and / or a second through hole is provided on the outer wall of the housing 1, which is directly opposite to and connected to the second receiving groove. When the user needs to remove the transmitter 31 and the receiver 32, he / she can reach into the first or second through hole from the outside of the housing 1 to remove the transmitter 31 or the receiver 32 without having to remove the entire housing 1, which is convenient and quick.

[0057] Optionally, a first switch door is rotatably provided at the opening of the first through hole, and the first switch door is used to selectively block the first through hole; a second switch door is rotatably provided at the opening of the second through hole, and the second switch door is used to selectively block the second through hole. Since both the first and second through holes are located on the outer wall of the housing 1, by providing the first and second switch doors, external dust can be prevented from entering the gap between the drum 2 and the housing 1 through the first or second through hole, thus affecting the normal use of the drum washing machine.

[0058] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention, the scope of which is determined by the scope of the appended claims.
