Description

Technical Field

[0001] The invention belongs to the technical field of washing machine transportation auxiliary equipment, and in particular relates to a washing machine packaging and transportation structure. Background Art

[0002] Washing machines include pulsator washing machines and drum washing machines. Drum washing machines mainly wash laundry by impact washing, which can form a washing structure that is not easily damaged. In order to facilitate operators to take and put clothes, drum washing machines are designed with an inclined drum washing machine in which the rotation axis is inclined and the rotating drum is opened to one side obliquely upward.

[0003] The inner drum module in a drum washing machine is the core component of the washing machine. Because the washing machine buffers vibrations, its design allows for jumping. However, during the transportation of the entire machine, the inner drum is subject to external transportation bumps or falls, causing damage to the inner drum module. In addition, commercial washing machines require a relatively large washing drum capacity. To ensure the reliability of the entire machine, the inner and outer drum modules and the shock absorbing system of the entire machine are designed to be relatively heavy.

[0004] In addition, inclined drum washing machines are widely used in engineering projects. During the transportation of the whole machine, violent transportation is inevitable, which may cause the whole machine to fall and cause damage to the whole machine and the inner drum module. Summary of the invention

[0005] The purpose of the present invention is to provide a washing machine packaging and transportation structure to solve the problems existing in the prior art of existing washing machines, especially inclined drum washing machines, which may cause the inner drum to be bumped and damaged during transportation due to the characteristics of their own working structure, thereby affecting the product quality.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions: The present invention proposes a washing machine packaging and transportation structure, which comprises: A reinforcement member, which is used to be connected to the outer wall of the box body, and at least one positioning hole and at least one limiting hole are formed on the reinforcement member; A fastening assembly, which is connected in the corresponding positioning hole and is used to connect the inner cylinder to the box body; The fastening assembly includes a guide, a fastener, and a limiter for connecting the guide to the reinforcement. The guide includes a guide sleeve and a positioning portion formed at one end of the guide sleeve. A guide channel is formed in the guide sleeve, and a limiter is formed on the outer wall of the guide sleeve. In the installed state, the fastener passes through the guide channel, and its connecting end is detachably connected to the inner cylinder. The guide sleeve is located between the inner cylinder and the reinforcement. A rotating neck is formed between the positioning portion and the guiding portion, and a limiting portion is formed on the guiding portion; after the guide sleeve is connected to the positioning hole, the guiding member is rotated at an angle until the limiting portion corresponds to the limiting hole, and the guiding portion is positioned on the reinforcing member through the limiting member.

[0007] In some embodiments of the present application, the shape of the positioning hole is adapted to the shape of a section that is perpendicular to the center line of the guide sleeve and passes through the limiting portion.

[0008] In some embodiments of the present application, at least one positioning notch is formed on the positioning portion, and a positioning protrusion matched with the position of the positioning notch is formed on the limiting member.

[0010] In some embodiments of the present application, a buffer portion is further provided between the fastening gasket and the positioning portion, and a through hole is formed in the middle of the buffer portion, the fastening gasket and the limiting member.

[0011] In some embodiments of the present application, the limiting member is a limiting gasket formed between the buffer portion and the positioning portion, and the positioning protrusion is formed on the limiting member and extends toward the positioning portion.

[0012] In some embodiments of the present application, both ends of the reinforcement are detachably connected to the box body by fastening screws, a profiling extending away from the box body is formed on the reinforcement, and the positioning hole and the limiting hole are both formed at the bottom of the profiling.

[0013] In some embodiments of the present application, two reinforcement members are spaced apart on the back side of the box body, and at least one positioning hole is provided at both ends of each reinforcement member. Correspondingly, a threaded hole is provided at the bottom of the inner tube, and an external thread is formed at the connecting end of the fastener, and the connecting end is detachably connected to the threaded hole.

[0014] In some embodiments of the present application, at least one reinforcement portion is formed on the side wall of the threaded hole, and the reinforcement portion is a groove-shaped structure that gradually expands away from the center of the threaded hole.

[0015] In some embodiments of the present application, a support member is further provided at the bottom of the inner cylinder, the bottom of the support member is connected to the bottom of the box body, and a conformal surface is formed on the support member that is in contact with the outer wall of the inner cylinder.

[0016] Compared with the prior art, the advantages and positive effects of the present invention are: The washing machine packaging and transportation structure involved in the present application is provided with a reinforcement member and a fastening assembly on the outer wall of the box body, which is used to strengthen the connection between the box body and the inner drum, and the movable connection between the inner drum and the box body is modified into a fixed connection.

[0025] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or reference letters in different examples, and this repetition is for the purpose of simplification and clarity, which itself does not indicate the relationship between the various embodiments and / or settings discussed.

[0026] refer to Figure 1The present application proposes a washing machine packaging and transportation structure, which is used to fix the inner drum 200 of the drum washing machine during transportation to prevent it from being shaken during transportation or handling, causing damage to the inner drum 200 module.

[0027] Especially for the inclined drum washing machine, due to its heavy weight, a compression spring assembly 700 and a shock absorber are arranged at the bottom of the inner drum, and a tension spring 500 is arranged above the inner drum to assist in supporting the inner drum.

[0028] The compression spring assembly 700 is used to bear the weight of the entire inner drum 200, including the weight of the inner drum 200 itself and the weight of clothes and washing water. Therefore, it is installed at the center of gravity of the inner drum as much as possible. It can also be installed in an eight-shaped manner, which not only bears the weight but also relieves vibration.

[0029] A plurality of tie rods 600 parallel to the rotation axis of the washing machine are arranged outside the inner drum 200 , and two ends of the tie rods 600 are respectively connected to the front counterweight block and the rear counterweight block of the washing machine.

[0030] The front counterweight and the rear counterweight can offset a portion of the centrifugal force generated during the operation of the inner drum, reducing the total centrifugal force that the tension spring 500 and the damping support rod need to overcome, and ultimately reducing the vibration and noise to which the entire washing machine is subjected.

[0031] The tension spring 500 is connected to the top of the box body 100 at the top and to the pull rod 600 at the bottom. A plurality of hanging positions are provided above the box body 100. The hanging position of the tension spring 500 can be adjusted at any time according to the center of gravity, thereby avoiding damage to the inner cylinder 200 caused by the tension spring 500 being directly hung on the inner cylinder 200.

[0032] refer to Figure 1-Figure 3 The washing machine packaging and transportation structure includes a reinforcement 300 and a fastening assembly 400. The reinforcement 300 is pre-fixed on the outer wall of the box body 100. One end of the fastening assembly 400 is connected to the reinforcement 300, and the other end extends inside the box body 100 until it is connected and fixed to the inner drum 200, thereby fixing the inner drum 200 on the box body 100.

[0033] The number of reinforcing members 300 can be multiple according to actual needs. They can be arranged horizontally or at an angle. When multiple reinforcing members 300 are arranged, the reinforcing members 300 are arranged at intervals.

[0034] In some embodiments of the present application, there are two reinforcement members 300, which are spaced apart from each other on the box body 100, and the reinforcement members 300 are installed horizontally. The two reinforcement members 300 are defined as a first reinforcement member 310 and a second reinforcement member 320 located below the first reinforcement member 310.

[0035] At least one positioning hole and at least one limiting hole 303 are respectively provided at both ends of the first reinforcement member 310 and the second reinforcement member 320 .

[0036] refer to Figure 4 The positioning hole is used to connect the fastening assembly 400, and the limiting hole 303 is used to position the guide member 410 in the fastening assembly 400.

[0037] The fastening assembly 400 is divided into a first fastening assembly 401 connected to the first reinforcement 310 and a second fastening assembly 402 connected to the second reinforcement 320 according to its specific connection position.

[0038] refer to Figure 11-Figure 14 The fastening assembly 400 includes a guide member 410, a fastener 420 and a limit member 430 for connecting the guide member 410 to the reinforcement member 300. The guide member 410 includes a guide sleeve 411 and a positioning portion 412 formed at one end of the guide sleeve 411. The size of the positioning portion 412 is larger than the positioning hole and is used to position the guide member 410 in the length direction.

[0039] A guide channel is formed in the guide sleeve 411, and the fastener 420 passes through the guide channel. The connecting end 421 of the fastener 420 is connected to the inner tube 200 after passing through the guide channel, and the operating end 422 of the fastener 420 is exposed outside the reinforcement 300, which is convenient for operators to install and disassemble.

[0040] A limiting portion is formed on the outer wall of the guide sleeve 411. During installation, the guide sleeve 411 is installed from the positioning hole to between the reinforcement 300 and the inner tube 200. After installation, the guide sleeve 411 is rotated so that the limiting portion abuts against the inner side of the reinforcement 300 to prevent the guide sleeve 411 from falling out of the positioning hole.

[0041] refer to Figure 6 In some embodiments of the present application, the reinforcement member 300 is arranged on the rear wall of the box body 100, the fastening assembly 400 is connected and fixed to the bottom of the inner cylinder 200, and an inner cylinder fixing position 210 is formed at the bottom of the inner cylinder 200. The number of the inner cylinder fixing positions 210 is set according to actual needs, and each fastening assembly 400 is respectively connected to the corresponding inner cylinder fixing position 210.

[0042] In some embodiments of the present application, four inner cylinder fixing positions 210 are dispersedly arranged around the bottom of the inner cylinder 200 , corresponding to at least two positioning holes respectively arranged on the first reinforcement member 310 and the second reinforcement member 320 , and each positioning hole corresponds to at least one limiting hole 303 .

[0043] Drum washing machines are divided into horizontal drum washing machines with a horizontal rotation axis and inclined drum washing machines with an inclined rotation axis. The packaging and transportation structure involved in the present application can be applied to both horizontal drum washing machines and inclined drum washing machines.

[0044] When it is applied to a horizontal drum washing machine, the first reinforcement member 310 and the second reinforcement member 320 have the same length from the inner drum 200, and the length of the fastening assembly 400 connected to the first reinforcement member 310 and the second reinforcement member 320 is also the same.

[0045] When applied to an inclined drum washing machine, since the opening end of the inclined drum washing machine is higher than the bottom of the inner drum 200 , the distance between the first reinforcement 310 and the bottom of the drum is greater than the distance between the second reinforcement 320 and the inner drum 200 .

[0046] Correspondingly, the length of the fastening assembly 400 connected to the first reinforcement 310 is greater than the length of the fastening assembly 400 connected to the second reinforcement 320 .

[0047] The first reinforcement 310 and the second reinforcement 320 are both horizontal fixed plate structures. Two first positioning holes 301 are provided at both ends of the first reinforcement 310 corresponding to the positions of the inner cylinder fixing positions 210, and two second positioning holes 302 are provided at both ends of the second reinforcement 320 corresponding to the two inner cylinder fixing positions 210 below the inner cylinder 200.

[0048] Fixed foot plates 304 are formed at both ends of the first reinforcement member 310 and the second reinforcement member 320 , respectively. The fixed foot plates 304 are provided with fixing holes 305 for fastening screws to fix the first reinforcement member 310 and the second reinforcement member 320 to the box body 100 .

[0049] A profile 306 extending away from the inner tube 200 is formed between the fixed foot plates 304 , and the first positioning hole 301 and the second positioning hole 302 are both arranged on the profile 306 corresponding to the first reinforcement member 310 and the second reinforcement member 320 .

[0050] refer to Figure 5 The distance between the two first positioning holes 301 on the oblique drum washing machine is smaller than the distance between the two second positioning holes 302. In order to improve the commonality between the first reinforcement 310 and the second reinforcement 320 and reduce the processing and mold opening cost, a group of first positioning holes 301 and a group of second positioning holes 302 are respectively arranged on the first reinforcement 310 and the second reinforcement 320.

[0051] refer to Figure 6-8 In some embodiments of the present application, the outer wall of the guide member 410 includes two opposite planar outer walls 4111 , and between the two adjacent planar outer walls 4111 is an outwardly protruding arc-shaped outer wall 4112 , which serves as a limiting portion of the guide member 410 .

[0052] The shape of the positioning hole matches the shape of a section perpendicular to the center line of the guide sleeve 411 and passing through the limiting portion.

[0053] The positioning portion 412 on the guide member 410 is arranged at the outer end of the guide sleeve 411. The size of the positioning portion 412 is larger than the size of the guide sleeve 411, that is, the size of the positioning portion 412 is larger than the size of the positioning hole, which provides a limit for the inward installation length of the guide member 410.

[0054] At least one positioning notch 4121 is formed on the positioning portion 412 . A limiting member 430 is installed on the outer side of the positioning portion 412 . A positioning protrusion 431 matching the position of the positioning notch 4121 is formed on the limiting member 430 .

[0055] The limiting member 430 is a limiting gasket formed between the buffer portion 440 and the positioning portion 412 . The positioning protrusion 431 is formed on the limiting member 430 and extends toward the positioning portion 412 .

[0056] In the installed state, the positioning protrusion 431 passes through the corresponding positioning notch 4121 and is inserted into the corresponding limiting hole 303 of the reinforcement member 300 to fix the position of the guide member 410 .

[0057] When the guide sleeve 411 passes through the positioning hole, the position of the positioning notch 4121 thereon is set at an angle to the limiting hole 303 on the reinforcing plate.

[0058] That is, after the guide sleeve 411 completely passes through the positioning hole, the guide member 410 rotates an angle before the stop member 430 and the stop hole 303 can be docked.

[0059] A rotating neck 413 is formed between the positioning portion 412 and the guide sleeve 411 to prevent interference when the guide member 410 rotates.

[0060] After the guide member 410 is installed, it is rotated at a certain angle, so that the position of the limit portion on the guide member 410 is deflected and contacts the reinforcement member 300, thereby fixing the position of the reinforcement member 300 in the length direction and preventing it from falling out of the positioning hole.

[0061] In other embodiments of the present application, the limiting member 430 may also be other limiting forms. For example, a first plug hole is opened on the positioning portion 412, a second plug hole is opened on the reinforcement member 300, and the limiting member 430 is a structure such as a latch.

[0062] The guide member 410 is installed and rotated to correspond to the first plug-in hole and the second plug-in hole, and the limiting member 430 connects the first plug-in hole and the second plug-in hole, which can also achieve the purpose of limiting the guide member 410.

[0063] refer to Figure 9-11In some embodiments of the present application, the inner cylinder fixing position 210 of the inner cylinder 200 is provided with a threaded hole 211 , and the connecting end 421 of the fastener 420 is formed with an external thread, and the connecting end 421 is detachably connected to the threaded hole 211 .

[0064] In order to improve the forming effect of the threaded hole 211 on the inner cylinder fixing position 210 and reduce deformation, burrs, etc., at least one reinforcement portion 212 is formed on the side wall of the threaded hole 211. The reinforcement portion 212 is a groove-shaped structure that gradually expands away from the center of the threaded hole 211.

[0065] The number of the reinforcement part 212 can be one, or a plurality of reinforcement parts 212 can be evenly distributed along the circumferential direction.

[0066] The axis of the threaded hole 211 and the axis of the corresponding positioning hole are located on the same straight line, which facilitates the connection of the fastener 420 and avoids distortion.

[0067] refer to Figure 12-14 A fastening gasket 450 is further provided between the connecting end 421 of the fastener 420 , the operating end 422 of the fastener 420 and the positioning portion 412 .

[0068] A buffer portion 440 is further provided between the fastening gasket 450 and the positioning portion 412 . The buffer portion 440 is made of a rubber material with a certain elasticity and can provide a certain buffering effect.

[0069] The buffer portion 440 , the fastening gasket 450 , and the middle of the stopper 430 are formed with through holes for the fastener 420 to pass through.

[0070] refer to Fig.15 A support member 900 is also provided at the bottom of the inner cylinder 200 . The bottom of the support member 900 is connected to the bottom of the box body 100 . A conformal surface 910 is formed on the support member 900 , which is in contact with the outer wall of the inner cylinder 200 and is used to further support the inner cylinder 200 .

[0071] The specific fixing process of the fastening assembly 400 is described in detail below: The connection method between any positioning hole on any reinforcement member 300 and the corresponding fastening assembly 400 is similar and will not be elaborated one by one.

[0072] After the first reinforcement member 310 and the second reinforcement member 320 are fixed to the box body 100 , the connecting end 421 of the fastener 420 is first passed through the fastening gasket 450 , the buffer portion 440 , the limit member 430 and the guide member 410 in sequence, and the positioning protrusion 431 corresponds to the positioning notch 4121 .

[0073] The guide member 410 passes through the corresponding positioning hole until the guide sleeve 411 is completely moved into the positioning hole, the neck 413 is rotated to correspond to the position of the positioning hole, and the positioning portion 412 is located outside the positioning hole.

[0074] The limiting member 430 and the guiding member 410 are rotated until the position of the positioning protrusion 431 on the limiting member 430 matches the limiting hole 303 on the reinforcing member 300 , and the positioning protrusion 431 is inserted into the limiting hole 303 to fix the position of the guiding member 410 .

[0075] By using a tool such as a wrench, the operating end 422 of the fastener 420 is rotated to rotate the connecting end 421 of the fastener 420 into the threaded hole 211 on the inner tube 200. The length of the fastener 420 is sufficient. When the connecting end 421 is rotated into the threaded hole 211, the operating end 422 presses the fastening gasket 450, the buffer part 440, and the limit part 430 onto the reinforcement 300 to achieve the connection and fixation of the fastening assembly 400.

[0076] A reinforcing member 300 and a fastening assembly 400 are provided on the outer wall of the box body 100 to strengthen the connection between the box body 100 and the inner tube 200, and to change the movable connection between the inner tube 200 and the box body 100 into a fixed connection.

[0077] The reinforcement member 300 on the box body 100 is used to provide a fixing basis for the connection of the fastening assembly 400 . One end of the fastener 420 in the fastening assembly 400 is fixed to the reinforcement member 300 , and the other end extends from the guide member 410 to the inner cylinder 200 and is connected to the inner cylinder 200 .

[0078] The guide member 410 can improve the structural strength of the fastener 420, fix the relative position between the inner cylinder 200 and the box body 100, and reduce the vibration of the inner cylinder 200; In addition, the limiting member 430 can fix the position of the guide member 410 to prevent the guide member 410 from rotating or falling out of the positioning hole during the connection process of the fastener 420, making the installation process of the fastener 420 simple, fast and easy to operate.

[0079] In the description of the above embodiments, specific features, structures, materials or characteristics may be combined in a suitable manner in any one or more embodiments or examples.

[0080] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.

[0081] An electric water heater uses electricity as its main energy source. The high-temperature heat generated after power is turned on directly heats the water stored in the electric water heater to prepare hot water.

[0082] An electric water heater usually includes a water tank, an electric heating component, an electric control board and other components. A water storage cavity is formed in the water tank to store the water to be heated. The electric heating component is inserted into the water storage cavity formed by the water tank. The electric control board is used to control the on and off operation of the electric heating component so that the water in the water tank is heated to a set temperature.

[0083] For the water tank of an electric water heater, the water tank generally includes an outer shell and an inner tank, and an insulation layer is formed between the outer shell and the inner tank. Among them, the outer shell is generally made of plastic material to meet the design requirements of beautiful and diverse shapes; the inner tank can be made of metal or plastic according to needs.

[0084] In addition, the insulation layer formed between the outer shell and the inner liner, commonly used insulation materials include: asbestos, sponge, foam plastic, polyurethane foam, etc. In conventional technology, in order to obtain a good insulation effect, the insulation layer is usually formed by foaming.

[0085] Among them, for the inner tank using a metal tank body, the interior of the inner tank is prone to corrosion due to the influence of water quality. For this reason, a magnesium rod is also configured on the water tank, and the magnesium rod is inserted into the water storage cavity inside the water tank.

[0086] Since magnesium is the metal with the lowest potential in the electrochemical series and is physiologically non-toxic, it is ideal for making magnesium rods to protect the inner liner. The size of the magnesium rod is directly related to the length of time the inner liner is protected and the size of the protective effect. The larger the magnesium rod, the better the protective effect and the longer the protection time.

[0087] The water tank is also provided with a water inlet pipe and a water outlet pipe. The water inlet pipe is used to transport cold water to the water storage cavity formed in the water tank, while the hot water in the water storage cavity is output from the water outlet pipe.

[0088] For the electric heating component, electric heating methods such as electric heating wire, magnetic energy or silicon tube heating can be used to heat the water stored in the water storage cavity.

[0089] As for the electric control board, it is used to receive the detection signals sent by relevant sensors (such as water temperature sensors, flow sensors), and at the same time, control the power on and off operation of the electric heating components.

[0090] When the electric water heater is working, the electric control board controls the electric heating component to be powered on for heating. When the water temperature in the water tank reaches the set value, the electric control board controls the electric heating component to be powered off.
