Description

Technical Field

[0001] The present invention relates to the technical field of measurement and detection, and particularly relates to an instrument for detecting the balance of a washing machine. Background Art

[0002] As a household appliance for automatically washing clothes, the washing machine is deeply loved by people due to its many advantages such as saving time and effort. With the development of China's social economy, the washing machine has become an essential household appliance in every household.

[0003] However, if the washing machine is not adjusted to a balanced state before use, it will vibrate violently and generate a large amount of noise during use. The internal components of the washing machine will also be subjected to vibration and impact, resulting in accelerated wear and even damage of the relevant components, thereby reducing the service life and use effect of the washing machine. Therefore, the washing machine must be adjusted to be balanced before use. However, the washing machine is usually installed in places such as the kitchen or bathroom where water inlet and drainage are more convenient. In order to ensure smooth drainage, these floors usually have a drainage slope of 2% to 5%. Therefore, the floor on which the washing machine is installed is usually a non-horizontal floor, resulting in the washing machine being in an unbalanced state after installation. At the same time, for practical purposes such as preventing water accumulation and for aesthetic purposes, the upper cover of the washing machine usually has a certain inclination or a certain arc. In order to improve the washing effect, the surface of the impeller disk at the bottom of the inner barrel of the washing machine has multiple protruding blades, and its surface also has a certain arc. Therefore, there is no place on the pulsator washing machine for placing a traditional spirit level, and the traditional spirit level cannot be directly used to adjust the balance of the washing machine. Moreover, for aesthetic and safety reasons, the four corner edges of the washing machine body are also made into an arc shape. Therefore, it is very difficult to adjust the balance of the washing machine by using methods such as visual inspection with a plumb line (a heavy object suspended by a rope). The above factors make it impossible to use traditional spirit levels or visual inspection methods to adjust the balance of the washing machine. Summary of the Invention

[0004] Aiming at the problem that it is difficult to adjust the balance of the washing machine, the present invention provides a spirit level specially designed for adjusting the balance of a pulsator washing machine, and the washing machine spirit level has the characteristics of simple structure and convenient operation.

[0005] In order to achieve the above object, the following technical solutions are proposed: A washing machine spirit level includes three main parts: a spirit level base, an extension tube, and a right-angle bracket. Among them, two mutually perpendicular spirit levels are embedded in the upper surface of the spirit level base, and four extension tube mounting holes are evenly distributed at intervals on the side wall. The extension tube is a rigid tubular structure. The right-angle bracket can be divided into a right-angle bracket cross bar and a right-angle bracket vertical bar according to its structural characteristics.

[0006] The appearance of the spirit level base is in the shape of a cylinder or a cube. Two spirit levels are embedded in the upper surface. The two spirit levels are in the same plane and perpendicular to each other, and the plane where the two spirit levels are located is parallel to the upper surface of the spirit level base. Four extension tube mounting holes are evenly distributed at intervals on the side wall of the spirit level base. The position of the extension tube mounting holes is lower than the position of the spirit levels, that is, the extension tube mounting holes and the spirit levels do not affect each other; the depth of the extension tube mounting holes is appropriate so that the extension tubes will not easily slip off after being inserted into the extension tube mounting holes. The two extension tube mounting holes in the symmetrical positions are on a straight line, that is, the front and rear extension tube mounting holes are on a straight line, the left and right extension tube mounting holes are on a straight line, and the straight line where the front and rear extension tube mounting holes are located is perpendicular to the straight line where the left and right extension tube mounting holes are located and in the same plane. The plane where the extension tube mounting holes are located is parallel to the plane where the spirit levels are located. There is a small groove running through the entire extension tube mounting hole directly above the inner wall of each extension tube mounting hole.

[0007] There are four extension tubes, which are of a rigid tubular structure. The outer diameter of the extension tubes matches the inner diameter of the extension tube mounting holes. There is a rib structure directly above the end of the extension tube inserted into the extension tube mounting hole. The rib structure of the extension tube matches the groove of the extension tube mounting hole. Only when the rib structure of the extension tube is aligned with the groove of the extension tube mounting hole can the extension tube be inserted into the extension tube mounting hole. The rib structure and the groove prevent the extension tube from rotating after being inserted into the extension tube mounting hole. A resilient head of the extension tube is fixed at the top of the end of the extension tube inserted into the extension tube mounting hole. The outer diameter of the resilient head of the extension tube is slightly larger than the outer diameter of the extension tube, and appropriate force is required to insert the extension tube into the extension tube mounting hole or pull the extension tube out of the extension tube mounting hole; the head of the resilient head of the extension tube is slightly smaller, making it easier to insert the extension tube into the extension tube mounting hole. There is a groove running through the entire extension tube directly above the inner wall of the extension tube. The groove of the extension tube and the rib structure are located on the inner and outer walls at the same position of the extension tube respectively.

[0008] There are four right-angle brackets, which are integrated L-shaped rods made of rigid materials. According to the structural characteristics, they can be divided into the crossbar of the right-angle bracket and the vertical rod of the right-angle bracket. The crossbar of the right-angle bracket and the vertical rod of the right-angle bracket are perpendicular to each other. The outer diameter of the crossbar of the right-angle bracket matches the inner diameter of the extension tube. There is a section of rib structure directly above the end of the crossbar of the right-angle bracket inserted into the extension tube. Only when the rib structure of the crossbar of the right-angle bracket is aligned with the groove of the extension tube can the crossbar of the right-angle bracket be inserted into the extension tube; a resilient head is fixed at the top of the crossbar of the right-angle bracket. The outer diameter of the resilient head of the crossbar of the right-angle bracket is slightly larger than the outer diameter of the crossbar of the right-angle bracket. Appropriate force is required to insert the crossbar of the right-angle bracket into the extension tube or pull the crossbar of the right-angle bracket out of the extension tube without easily slipping out of the extension tube. The head of the resilient head of the crossbar of the right-angle bracket is slightly smaller, making it easier to insert the crossbar of the right-angle bracket into the extension tube.

[0009] The beneficial effects of the present invention are: 1. Wide range of applications: The extension tube enables the present invention to be used for washing machines of various models (different sizes) or other tubular or barrel-shaped devices that need to ensure a vertical state. The right-angle bracket enables the present invention to also measure across obstacles; 2. Simple structure: The present invention only includes a spirit level seat embedded with a spirit level tube, four extension tubes, and a right-angle bracket. The structures of the spirit level seat, extension tubes, and right-angle bracket are also very simple; 3. Reusable: Compared with the method of embedding a spirit level tube in a washing machine, the present invention can be reused infinitely and used in different places, which is more economical and affordable; 4. Convenient assembly and storage: Insert the right-angle bracket into the extension tube and insert the extension tube into the spirit level seat to complete the assembly, which is convenient to use; Remove the extension tube from the spirit level seat and insert all the crossbars of the right-angle bracket of the right-angle bracket into the extension tube. All components together only occupy a very small space, which is convenient for storage and carrying. Brief Description of the Drawings

[0013] The realization, functional features, and advantages of the object of the present invention will be further described in conjunction with embodiments with reference to the drawings. Detailed Embodiments

[0014] It should be understood that the specific embodiments described herein are only used to explain and illustrate the present invention, and are not used to limit the present invention. Any modifications, equivalent replacements, improvements, variations, etc. made by those of ordinary skill in the art within the scope of the principles and purposes of the present invention all fall within the protection scope of the present invention.

[0015] Figure 1 It is a schematic exploded three-dimensional structure diagram of the present invention, Figure 2 It is a longitudinal sectional view during measurement of the present invention. As Figure 1 、 Figure 2 shown, a washing machine level mainly includes three main parts: a spirit level seat 2, an extension tube 5, and a right-angle bracket 7.

[0016] As Figure 1As shown in the figure, the appearance of the spirit level base 2 is in the shape of a cylinder or a cube. Two spirit levels 1 that are perpendicular to each other and in the same plane are embedded in the upper surface of the spirit level base 2. The plane where the two perpendicular spirit levels 1 are located is parallel to the upper surface of the spirit level base. According to the position of the bubble in the spirit level 1, it can be judged whether the spirit level 1 is in a horizontal state. When the bubbles in both spirit levels 1 are in the center of the spirit level, the plane where the two spirit levels 1 are located is in a horizontal state. Four extension tube mounting holes 3 are evenly distributed at intervals on the side wall of the spirit level base 2. The position of the extension tube mounting holes 3 is lower than the position of the spirit level 1, that is, the extension tube mounting holes 3 and the spirit level 1 do not affect each other; the depth of the extension tube mounting holes 3 is appropriate, so that the extension tube 5 will not easily slip off after being inserted into the extension tube mounting holes 3. The two symmetric extension tube mounting holes 3 are on a straight line, that is, the front and rear extension tube mounting holes 3 are on a straight line, the left and right extension tube mounting holes 3 are on a straight line, and the straight line where the front and rear extension tube mounting holes 3 are located is perpendicular to and in a plane with the straight line where the left and right extension tube mounting holes 3 are located. The plane where the extension tube mounting holes 3 are located is parallel to the plane where the two spirit levels 1 are located. There is a groove running through the entire extension tube mounting hole 3 directly above the inner wall of the extension tube mounting hole 3.

[0017] As Figure 1 shown in the figure, the extension tube 5 is a rigid tubular structure, and the outer diameter size matches the inner diameter of the extension tube mounting hole 3. There is a rib structure at the upper end of the extension tube 5 inserted into the extension tube mounting hole 3, which matches the groove of the extension tube mounting hole 3. The rib structure of the extension tube 5 must be aligned with the groove of the extension tube mounting hole 3 to insert the extension tube 5 into the extension tube mounting hole 3. After the extension tube 5 is inserted into the extension tube mounting hole 3, the rib structure of the extension tube 5 and the groove of the extension tube mounting hole 3 prevent the extension tube from rotating; a extension tube elastic head 4 made of rubber or silica gel or other materials with strong elasticity and large surface friction is fixed at the top of the end of the extension tube 5 inserted into the extension tube mounting hole 3. The diameter of the extension tube elastic head 4 is slightly larger than the inner diameter of the extension tube mounting hole 3, so that after the extension tube 5 is inserted into the extension tube mounting hole 3, the friction between the extension tube elastic head 4 and the inner wall of the extension tube mounting hole 3 is large. Therefore, appropriate force is required to insert the extension tube 5 into the extension tube mounting hole 3 or pull the extension tube 5 out of the extension tube mounting hole 3; the head of the extension tube elastic head 4 is slightly smaller, making it easier to insert the extension tube 5 into the extension tube mounting hole 3; when the extension tube 5 is inserted into the extension tube mounting hole 3, the extension tube elastic head 4 can fix the extension tube 5 firmly in the extension tube mounting hole 3 and prevent it from slipping out of the extension tube mounting hole 3 easily. There is a groove running through the entire extension tube 5 at the position corresponding to the rib structure on the inner wall directly above the extension tube 5, that is, the groove and the rib structure of the extension tube 5 are on the inner and outer walls at the same position of the extension tube 5: the rib structure is on the outer wall of the extension tube 5, and the groove is on the inner wall of the extension tube 5 at the same position as the rib structure.

[0018] As Figure 1As shown in the figure, the right-angle bracket 7 is an integrated L-shaped rod made of a hard material. According to its structural characteristics, it can be divided into two parts: the crossbar 8 of the right-angle bracket and the vertical rod 9 of the right-angle bracket. The crossbar 8 of the right-angle bracket is perpendicular to the vertical rod 9 of the right-angle bracket. The outer diameter of the crossbar 8 of the right-angle bracket matches the inner diameter of the extension tube 5. There is a rib structure directly above one end of the crossbar 8 of the right-angle bracket inserted into the extension tube 5. The rib structure of the crossbar 8 of the right-angle bracket must be aligned with the groove on the inner wall of the extension tube 5 to be inserted into the extension tube 5. The groove and the rib structure prevent the crossbar 8 of the right-angle bracket from rotating after being inserted into the extension tube 5. A right-angle bracket crossbar elastic head 6 made of rubber or silica gel or other materials with strong elasticity and large surface friction is fixed at the top of the end of the crossbar 8 of the right-angle bracket inserted into the extension tube 5. The right-angle bracket crossbar elastic head 6 is slightly larger than the inner diameter of the extension tube 5. After the crossbar 8 of the right-angle bracket is inserted into the extension tube 5, the friction between the right-angle bracket crossbar elastic head 6 and the inner wall of the extension tube 5 is large. Therefore, appropriate force is required to insert the crossbar 8 of the right-angle bracket into the extension tube 5 or pull it out from the extension tube 5, and the crossbar 8 of the right-angle bracket will not easily slip out of the extension tube 5 after being inserted into the extension tube 5. The head of the right-angle bracket crossbar elastic head 6 is slightly smaller, making it easier to insert the crossbar 8 of the right-angle bracket into the extension tube 5.

[0019] Insert the crossbars 8 of the four right-angle brackets 7 into the four extension tubes 5 respectively, and then insert the four extension tubes 5 into the four extension tube mounting holes 3 of the spirit level base 2 to complete the assembly of the present invention. The crossbar 8 of the right-angle bracket can move within the extension tube 5, so that the distance between the vertical rod 9 of the right-angle bracket 7 and the spirit level base 2 can be adjusted within a certain range, so that the washing machine level can be used to measure washing machines of various specifications and models (i.e., different sizes). The rib structure of the crossbar 8 of the right-angle bracket, the rib structure and groove of the extension tube 5, and the groove of the extension tube mounting hole 3 make the vertical rods 9 of the four right-angle brackets 7 perpendicular to the plane where the two spirit levels 1 are located. That is, when the plane where the two spirit levels 1 are located is horizontal, the four vertical rods of the right-angle brackets must be in a vertical state.

[0020] Washing machines are usually installed on non-level floors, and the upper cover usually has a certain inclination or a certain curvature. The surface of the impeller disc 11 at the bottom of the inner barrel 10 of the washing machine has multiple protruding blades, and its surface also has a certain curvature. Therefore, it is impossible to directly use a traditional level to adjust the balance of the washing machine. However, the structural feature of a pulsator washing machine is that when the washing machine is in a balanced state, the inner wall of its inner barrel is in a vertical state. Therefore, the present invention adopts a combination of a right-angle bracket 7 and a traditional spirit level 1 to realize the measurement of adjusting the balance of the washing machine. As Figure 2As shown in the figure, when in use, insert the four extension tubes 5 into the four extension tube mounting holes 3 on the spirit level base 2 respectively, and then insert the cross bars 8 of the right-angle brackets 7 of the four right-angle brackets into the four extension tubes 5 respectively. After the assembly is completed, place it in the inner barrel of the washing machine, and pull the right-angle brackets 7 outwards so that the vertical bars 9 of the four right-angle brackets are closely attached to the inner wall of the inner barrel of the washing machine. In this way, the plane where the spirit level 1 is located is perpendicular to the inner wall of the inner barrel 10 of the washing machine. When adjusting the level-adjusting feet of the washing machine so that the bubbles in the two spirit levels 1 are both in the center of the spirit level 1, the plane where the two spirit levels 1 are located is in a horizontal state. At this time, the inner wall of the inner barrel 10 of the washing machine is in a vertical state. When the inner barrel 10 of the washing machine is in a vertical state, the whole washing machine is in a balanced state. Therefore, by adjusting the level-adjusting feet of the washing machine and observing the positions of the bubbles in the two spirit levels 1, the balance adjustment of the washing machine can be easily completed.
