Description

Technical Field

[0001] This application relates to the field of household appliance technology, and in particular to a leveling instrument, a leveling control system, and a cleaning device. Background Technology

[0002] Currently, various devices, including but not limited to household appliances, should be installed in specific orientations. For example, household appliances such as washing machines and dryers should be installed horizontally; otherwise, the center of gravity of the drum will shift during rotation, resulting in vibration, noise, and even accelerated wear of components.

[0003] During equipment leveling, operators typically need to use a spirit level to determine if the equipment has been adjusted to a horizontal position. This presents two problems: First, bubble levels are usually used, and the operator's visual judgment of the bubble level's accuracy further increases the error. Second, the spirit level needs to be fixed to the equipment's horizontal surface. In some cases, the equipment has a specific appearance that may not have a horizontal surface, or fixing the spirit level to a horizontal surface may be difficult. Utility Model Content

[0042] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0044] In the description of this application, unless otherwise stated, " / " indicates that the objects before and after are in an "or" relationship. For example, A / B can mean A or B. "And / or" in this application is merely a description of the relationship between the related objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist simultaneously, and B exists alone. A and B can be single or multiple. Furthermore, in the description of this application, "at least one of the following" or similar expressions refer to any combination of these items, including any combination of single or multiple items. For example, at least one of a, b, and c can represent: a, b, c, a+b, a+c, b+c, a+b+c, where a, b, and c can be single or multiple. As another example, at least one of a, b, or c can represent: a, b, c, a+b, a+c, b+c, a+b+c, where a, b, and c can be single or multiple.

[0045] To illustrate the technical solutions described in this application, the following detailed description is provided in conjunction with specific drawings and embodiments.

[0046] like Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, this application embodiment first provides a leveling instrument 8, which is used to be set at the bottom of the device to be leveled in order to detect whether the bottom of the device to be leveled is level.

[0047] Specifically, such as Figure 1 , Figure 2 and Figure 5 As shown, the leveling instrument 8 includes a base 81, a mounting component 82, an angle sensor 83, and a reset component 84. Figure 6 and Figure 7As shown, the base 81 has a reference surface 810 on one side along the first direction X, and the mounting member 82 has a first end 8211 and a second end 8212 disposed along the second direction Y. The first end 8211 and the second end 8212 are respectively slidably connected to the base 81 along the first direction X, and the second direction Y is inclined to the first direction X. Figure 1 and Figure 2 As shown, the mounting member 82 has an abutment surface 8250 that is opposite to the reference surface 810 and protrudes from the base 81 along the first direction X. The angle sensor 83 is fixedly mounted on the mounting member 82, and the reset member 84 is disposed between the first end 8211 of the mounting member 82 and the base 81, and between the second end 8212 of the mounting member 82 and the base 81. The reset member 84 is used to drive the mounting member 82 to move away from the reference surface 810 along the first direction X.

[0048] In practical applications, the device to be leveled is installed and used on a mounting surface. This mounting surface can be the ground, countertop, desktop, cabinet surface, bracket surface, etc. In some embodiments of this application, the device to be leveled can be any device with height adjustment and leveling requirements, including but not limited to washing machines, dryers, washer-dryer combos, shoe washers, dishwashers, and even refrigerators and freezers. The height adjustment of the device to be leveled is based on the mounting surface. The mounting surface is a horizontal plane.

[0049] The lower side of the equipment to be leveled is the mounting plane. During the application of this leveling instrument 8, the reference surface 810 is the lower surface of the base 81, the contact surface 8250 is the upper surface of the mounting surface, and the first direction X is the vertical direction.

[0050] When the leveling instrument 8 is positioned between the bottom of the device to be leveled and the mounting plane, the reference surface 810 abuts against the bottom of the device. If, in the horizontal direction, there is an angle between the bottom of the device to be leveled and the horizontal plane, then there is also an angle between the abutting surface 8250 and the horizontal plane. Consequently, the angle sensor 83 mounted on the mounting component 82 can detect that its position is not horizontal at this time. Figure 7 As shown, taking the second end 8212 being higher than the first end 8211 as an example, as the leveling device is adjusted, the reset member 84 located at the first end 8211 gradually pushes the first end 8211 of the mounting member 82 to rise until the bottom of the leveling device in the second direction Y is parallel to the horizontal plane. At this time, the reference plane 810 is parallel to the horizontal plane, and the angle sensor 83 can detect that its own position is horizontal and output the corresponding horizontal positioning signal.

[0051] The leveling instrument 8 provided in this embodiment has a base 81 with a reference surface 810 that can be fitted with a mounting plane, and a mounting member 82 with an abutment surface 8250 for fitting with the bottom of the device to be leveled. The height difference between the first end 8211 and the second end 8212 of the mounting member 82 reflects the degree of inclination of the bottom of the device to be leveled. The leveling instrument 8 does not need to be installed on the device to be leveled. Therefore, the device to be leveled does not need to reserve a horizontal installation area for the leveling instrument 8. At the same time, the inclination of the bottom of the device to be leveled is detected by the angle sensor 83, eliminating the need for manual visual judgment, which can improve the accuracy of the detection results and the leveling effect, and improve the leveling efficiency.

[0052] The second direction Y can be horizontal, that is, perpendicular to the first direction X. When there is a height difference between the first end 8211 and the second end 8212 of the mounting member 82, it indicates that the mounting member 82 and its abutment surface 8250 are not horizontal. When the first end 8211 and the second end 8212 of the mounting member 82 are at the same horizontal height, it indicates that the mounting member 82 and its abutment surface 8250 are in a horizontal state.

[0053] In other embodiments, the second direction Y may also be tilted but not perpendicular to the first direction X. The key is to ensure that the horizontality of the bottom of the device to be leveled is reflected by the horizontality of the contact surface 8250.

[0054] The accompanying drawings of this application embodiment illustrate an example where the second direction Y is perpendicular to the first direction X. For example... Figure 1 and Figure 5 As shown, in some embodiments of this application, the mounting member 82 includes a mounting plate 821 and an abutment plate 825 connected along the first direction X. The mounting plate 821 is located within the receiving cavity 8110 of the base 81 and has the aforementioned first end 8211 and second end 8212. The reset member 84 is also located within the receiving cavity 8110 of the base 81. At least a portion of the abutment plate 825 is located outside the base 81 and has an abutment surface 8250. The purpose of this arrangement is that the base 81 has a certain size in the first direction X, and the internal receiving cavity 8110 can be used to hide the mounting plate 821 and the reset member 84, etc., and provide a certain degree of protection for the mounting plate 821 and the reset member 84. During the use and non-use of the level detector 8, external objects can be prevented from damaging the reset member 84 and the mounting plate 821, thereby avoiding affecting the movement of the mounting member 82 and the angle sensor 83 along the first direction X, and also avoiding affecting the normal function of the angle sensor 83.

[0055] like Figure 1 , Figure 4 , Figure 5 As shown, in some embodiments of this application, the base 81 includes a base body 811 and a connecting plate 812; as Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the aforementioned receiving cavity 8110 is formed inside the base body 811. A reference surface 810 is provided on the base body 811, and a connecting plate 812 is connected to the inner periphery of the end of the base body 811 opposite to its reference surface 810. The first end 8211 and the second end 8212 are respectively slidably connected to the connecting plate 812 along a first direction X. Thus, the connecting plate 812 provides sliding positions for the first end 8211 and the second end 8212 in the first direction X, and the base body 811 reserves space for the sliding of the first end 8211 and the second end 8212 in the first direction X.

[0056] In some embodiments, such as Figure 3 and Figure 5 As shown, the connecting plate 812 is provided with a through hole 8120 along the first direction X. The first end 8211 and the second end 8212 of the mounting plate 821 are located on the side of the connecting plate 812 facing the reference surface 810, that is, in the receiving cavity 8110 of the base body 811. The abutment plate 825 is fixedly connected to the mounting plate 821 through the through hole 8120.

[0057] The purpose of this arrangement is that the first end 8211 and the second end 8212 of the mounting plate 821 can be slidably connected to the connecting plate 812 along the first direction X. At the same time, the mounting plate 821 can be enclosed and protected by the connecting plate 812 and the base body 811.

[0058] The base body 811 can be a closed, enclosed structure, surrounding the mounting plate 821, such as... Figure 5 As shown. In other alternative embodiments, the base body 811 may also be non-enclosed.

[0059] like Figure 3 , Figure 6 and Figure 7 As shown, along the second direction Y, the inner dimension of the through hole 8120 is larger than the outer dimension of the abutment plate 825. This prevents the two ends of the abutment plate 825 along the second direction Y from contacting the inner wall of the through hole 8120, thereby allowing the abutment plate 825 to move and tilt smoothly.

[0060] like Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, in some embodiments of this application, the mounting member 82 further includes a plurality of sliding connectors 827. One end of the sliding connector 827 along the first direction X (such as the upper end) is fixedly connected to the connecting plate 812, and the reset members 84 are respectively disposed between the other end of the sliding connector 827 along the first direction X (such as the lower end) and the mounting plate 821. Thus, the reset members 84 can provide a reset force to the mounting plate 821 along the sliding connector 827.

[0061] Taking two sliding connectors 827 as an example, the two sliding connectors 827 are respectively provided for the first end 8211 and the second end 8212. That is, a reset member 84 is provided between the other end of one sliding connector 827 along the first direction X (as shown below) and the first end 8211, and the other reset member 84 is provided between the other end of the other sliding connector 827 along the first direction X (as shown below) and the second end 8212. Therefore, the first end 8211 and the second end 8212 can slide independently along the corresponding sliding connector 827 in the first direction X. The reset member 84 can push and reset the first end 8211 and the second end 8212 upward along the first direction X.

[0062] In some alternative embodiments, the side surface of the connecting plate 812 facing the reference surface 810 is parallel to the reference surface 810. The purpose of this arrangement is that when the reset member 84 causes the first end 8211 and the second end 8212 to abut against the side surface of the connecting plate 812 facing the reference surface 810, the mounting plate 821 is also in a horizontal state.

[0063] In some alternative embodiments, the reset member 84 is in a compressed state when the first end 8211 and the second end 8212 abut against the side surface of the connecting plate 812 facing the reference surface 810. That is, the reset member 84 causes the first end 8211 and the second end 8212 to abut against the side surface of the connecting plate 812 facing the reference surface 810 with a certain pressure. This ensures that the mounting plate 821 is subjected to a force from the reset member 84 at any time and in any state, which can prevent the mounting plate 821 from shaking and avoid interference and influence on the detection results of the angle sensor 83.

[0064] In some embodiments, the reset member 84 is a compression spring, which is sleeved on the sliding connector 827. In other alternative embodiments, the reset member 84 can be a cylindrical structure made of elastic material, etc.

[0065] like Figure 4 and Figure 5 As shown, in some embodiments of this application, the abutment plate 825 includes a plurality of connecting ears 8251. Along the first direction X, the connecting ears 8251 are located on the side of the abutment surface 8250 near the mounting plate 821, and the connecting ears 8251 are fixedly connected to the side of the mounting plate 821 opposite to the reference surface 810.

[0066] Optionally, the connecting ear 8251 can be fixedly connected to the side surface of the mounting plate 821 opposite to the reference surface 810 by means of welding, bonding, locking with locking member 828, etc.

[0067] In some alternative embodiments, in the first direction X, the connecting ear 8251 is positioned lower than the abutment surface 8250. This is to prevent the fixed connection between the connecting ear 8251 and the mounting plate 821 from interfering with the contact between the abutment surface 8250 and the bottom of the device to be leveled. For example, when the connecting ear 8251 is connected to the mounting plate 821 by locking it with a locking member 828 (such as a screw), due to the height difference between the connecting ear 8251 and the abutment surface 8250, the end of the locking member 828 facing away from the reference surface 810 can still be lower than the abutment surface 8250, and this end will not contact the bottom of the device to be leveled.

[0068] The angle sensor 83 can be fixedly mounted on the mounting plate 821 or on the abutment plate 825.

[0069] In some embodiments of this application, such as Figure 4 , Figure 6 and Figure 7 As shown, a second mounting groove 8252 is provided on the side of the abutment plate 825 facing the mounting plate 821 and / or on the side of the mounting plate 821 facing the abutment plate 825, and the angle sensor 83 is disposed in the second mounting groove 8252. That is, in the first direction X, the angle sensor 83 is disposed between the mounting plate 821 and the abutment plate 825, and the angle sensor 83 is protected by the mounting plate 821 and the abutment plate 825. During the movement of the mounting member 82 along the first direction X and the tilting relative to the first direction X, the angle sensor 83 will not come into contact with other objects, and therefore will not be damaged.

[0070] like Figure 4 , Figure 6 and Figure 7 As shown, in some embodiments of this application, the surface of the abutment plate 825 facing the mounting plate 821 is provided with the aforementioned second mounting groove 8252. The purpose of this arrangement is that, since the abutment surface 8250 is positioned higher, the second mounting groove 8252 precisely utilizes the space below the abutment surface 8250 on the abutment plate 825. Therefore, there is no need to create a groove on the mounting plate 821, and the mounting plate 821 can be a relatively flat plate structure, simplifying the structure and manufacturing process of the mounting plate 821.

[0071] In other alternative embodiments, the angle sensor 83 may also be disposed on the side of the mounting plate 821 opposite to the abutment plate 825. Optionally, the second mounting groove 8252 may be disposed on the surface of the mounting plate 821 opposite to the abutment plate 825. This is only necessary to ensure that the angle sensor 83 is fixed to the mounting member 82 and that the angle sensor 83 is not damaged as the mounting member 82 moves.

[0072] In some embodiments of this application, the connecting ear 8251 is detachably connected to the side of the mounting plate 821 facing away from the reference surface 810. The purpose of this arrangement is to facilitate the maintenance or replacement of the angle sensor 83 when it is located between the mounting plate 821 and the abutment plate 825; in some cases, the height adjustment requirements of different leveling devices can be met by replacing the abutment plate 825 with one of different heights.

[0073] like Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, in some embodiments of this application, the mounting component 82 further includes a plurality of gaskets 826, which are detachably mounted between the connecting ear 8251 and the mounting plate 821. Specifically, as shown... Figure 4 As shown, the locking member 828 has a washer 826 inserted through it. Thus, by removing the locking member 828 and placing an appropriate number and / or thickness of washer 826 between the connecting ear 8251 and the mounting plate 821, the height of the mounting member 82 can be adapted to the height adjustment requirements of the equipment to be leveled.

[0074] like Figure 2 As shown, in some embodiments of this application, at least one side of the second mounting groove 8252 has an opening 8254 along the third direction Z; the third direction Z is perpendicular to the first direction X and the second direction Y. The purpose of this arrangement is that the opening 8254 on this side is used for wiring, specifically for the power line, communication signal, etc. of the angle sensor 83.

[0075] In some alternative embodiments of this application, along the third direction Z, one side of the second mounting groove 8252 has an opening 8254.

[0076] In some embodiments of this application, the connecting ears 8251 described above are disposed on both sides of the abutment plate 825 along the second direction Y. The purpose of this arrangement is that the position of the connecting ears 8251 on the abutment plate 825 and the position of the opening 8254 do not affect each other.

[0077] In some alternative embodiments of this application, such as Figure 1 , Figure 3 and Figure 5As shown, the mounting component 82 also has a guide surface 8253, which is connected to the abutment surface 8250 along a third direction Z. Specifically, the guide surface 8253 and the abutment surface 8250 are connected along a first direction X on the side away from the opening 8254, and the guide surface 8253 is inclined towards the reference surface 810 in the direction away from the abutment surface 8250. That is to say, the guide surface 8253 is a surface that is inclined downwards and away from the abutment surface 8250. The purpose of this arrangement is to facilitate the placement of the leveling instrument 8 into the space below the bottom of the device to be leveled. Specifically, with the side of the guide surface 8253 away from the abutment surface 8250 facing the device to be leveled, since the side of the guide surface 8253 away from the abutment surface 8250 is lower, the guide surface 8253 can easily slide into the space below the bottom of the device to be leveled. Furthermore, the abutment surface 8250 enters the space below the bottom of the device to be leveled and abuts against the bottom of the device to be leveled.

[0078] For equipment to be leveled, it has specific orientations during installation and use, which are defined here as its height direction, depth direction, and width direction. The height direction is the vertical direction, the depth direction is the front-to-back direction, and the width direction is the left-to-right direction.

[0079] When using the leveling instrument 8 to level the equipment, if the guide surface 8253 is pushed into the bottom of the equipment along the width direction, then the second direction Y mentioned above is the depth direction. At this time, the height of the front and rear ends of the equipment can be adjusted until the front and rear ends of the equipment are at the same height. If the guide surface 8253 is pushed into the bottom of the equipment along the depth direction, then the second direction Y mentioned above is the width direction. At this time, the height of the left and right ends of the equipment can be adjusted until the left and right ends of the equipment are at the same height.

[0080] In practical applications, the leveling instrument 8 can be used to level the front and rear ends of the leveling device, or the leveling instrument 8 can be used to level the left and right ends of the leveling device, or the leveling instrument 8 can be used to level both the front and rear ends and the left and right ends of the leveling device.
