Description

Technical Field

[0001] The present invention belongs to the technical field of household electrical appliances, and in particular relates to a household electrical appliance. Background Art

[0002] With the development of technology, more and more home appliances have entered the home. In daily life, people usually need to embed home appliances into home decoration or cabinets for various reasons such as expanding indoor space and beautifying decoration, especially pull-out pulsator washing machines. The existing pulsator washing machines are basically opened from the top due to the structure of the washing barrel. In this way, a certain space needs to be reserved above the washing machine to open the cover and put in clothes, so that the washing machine cannot be well embedded in the home decoration or cabinets, etc., making it difficult for the washing machine to be integrated into the integrated design of home decoration, which is not conducive to the integrity of home decoration.

[0003] In order to integrate household appliances with home decoration or cabinets, household appliances are usually set in a pull-out manner. Taking a pull-out pulsator washing machine as an example, a lifting device and rollers are usually set on the washing body of the pull-out pulsator washing machine. The lifting device usually includes a motor and a connecting rod. In order to reduce production costs, the connecting rod is set to extend from the front end of the washing body to the rear end of the washing body, so that the connecting rod can be connected to at least two rollers, so that one motor can at least drive the lifting and lowering of the two rollers. However, since the connecting rod extending from the front end of the washing body to the rear end of the washing body is long and has a low load-bearing capacity, the connecting rod will be deformed due to the pressure of the washing body during the long-term pulling out and pushing back of the washing body, which will cause the washing body to shake or even be difficult to pull out or push back.

Figure 2 It is a longitudinal sectional view of a home appliance in an embodiment of the present invention at a middle position along a direction in which the washing body is pulled out when the first slide rail is located at a second preset position. Figure 3 is along Figure 2 Section view along line AA. Figure 4 It is a schematic diagram of the three-dimensional structure when the first slide rail of the household appliance of the present invention is located at the first preset position. Figure 5 yes Figure 4 A partial enlarged view of area B. Figure 6 It is a longitudinal sectional view of a home appliance in an embodiment of the present invention at a middle position along a direction in which the washing body is pulled out when the first slide rail is located at a first preset position.

[0041] like Figure 1 See also Figure 2-Figure 6 , in order to solve the problem that the connecting rod structure commonly used in the existing washing machine lifting device with a pull-out structure is relatively complex and has a low bearing capacity, so that the connecting rod structure will be deformed due to the pressure of the washing body during the long-term pulling out and pushing back of the washing body, which will cause the washing body to shake or even be difficult to pull out or push back. The present invention provides a household appliance, the household appliance includes a detachable shell 1 (the bottom of the shell is shown in the figure) and a washing body 2 (the support body at the bottom of the washing body is shown in the figure), the household appliance also includes a driving transmission device 3, the driving transmission device 3 is arranged between the shell 1 and the washing body 2, and is configured to fix the washing body 2 with the shell 1 when the driving transmission device 3 is lowered, so that the washing body 2 can be embedded in the shell 1, and is also configured to release the fixed connection between the washing body 2 and the shell 1 when the driving transmission device 3 is lifted, so that the washing body 2 slides relative to the ground to pull the washing body 2 out of the shell 1.

[0042] The driving transmission device 3 of the present invention is constructed to fix the washing body 2 and the outer shell 1 when it is lowered, and to release the fixed connection between the washing body 2 and the outer shell 1 when it is lifted, so that the washing body 2 slides relative to the ground to pull the washing body 2 out of the outer shell 1, which is equivalent to achieving the effect of fixing and sliding the washing body 2 by lowering and lifting the driving transmission device 3 itself, so that the present invention can make the driving sensor device have a simple and firm structure, so that the washing body 2 has good stability in both the pulling out and embedding processes, thereby improving user satisfaction.

[0043] In addition, the inventors also discovered in the process of implementing the present invention that in the prior art, household appliances drive a connecting rod structure through a motor to drive the raising and lowering of rollers connected to the connecting rod structure at the front and rear ends of the washing machine to achieve the pulling out and embedding of the washing body 2. The connecting rod in the connecting rod structure will be deformed due to the gravity of the washing body 2, which will cause the washing body 2 to shake during the pulling out and embedding process, and even cause the washing body 2 to have difficulty in sliding.

[0044] The driving transmission device 3 of the present invention is constructed so that the washing body 2 is fixedly connected to the outer shell 1 when it is lowered, and the washing body 2 is released from the fixed connection with the outer shell 1 when it is lifted, so that the washing body 2 slides relative to the ground. Compared with the prior art, the driving sensor device of the present invention only needs to have a simple and firm structure, avoiding the deformation of the connecting rod in the connecting rod structure due to the gravity of the washing body 2, and improving the stability of pulling out and embedding the washing body 2 compared with the prior art.

[0045] As a possible implementation, Figure 1 See also Figure 2-Figure 6 The driving transmission device 3 includes: a driving member 31 and a transmission mechanism 32. The driving member 31 provides power for the driving transmission device 3. The driving member 31 and the transmission mechanism 32 are correspondingly connected to the washing body 2, and the transmission mechanism 32 is configured to be driven by the driving member 31 to be lowered or raised to achieve the insertion or extraction of the washing body 2 relative to the housing 1.

[0046] As a possible implementation, Figure 1 See also Figure 2-Figure 6 The driving member 31 is a motor, and the transmission mechanism 32 includes a first-stage transmission mechanism 321 and a second-stage transmission mechanism 322. The first transmission mechanism is connected to the motor and is configured to convert the rotational motion of the motor into a lifting motion. The second transmission mechanism 32 is correspondingly connected to the first transmission mechanism 32 and the washing body 2 and is configured to be driven by the motor and the first transmission mechanism 32 to descend or lift up, so as to achieve the embedding or pulling out of the washing body 2 relative to the housing 1.

[0047] Of course, in other embodiments, the driving member 31, that is, the power source, may also be a common power source such as a cylinder or an electric push rod.

[0048] As a possible implementation, Figure 1 See also Figure 2-Figure 6 The first-stage transmission mechanism 321 includes: a traction wheel 3211 and a pull rope 3212. The traction wheel 3211 is sleeved on the output shaft of the motor to rotate with the output shaft of the motor. The upper end of the pull rope 3212 (the end away from the bottom of the housing 1) is wound around the traction wheel 3211, and the lower end of the pull rope 3212 (the end close to the bottom of the housing 1) is connected to the second-stage transmission mechanism 322 to drive the second-stage transmission mechanism 322 to be lowered or raised.

[0049] Among them, the traction wheel 3211 and the pull rope 3212 form a knot connection, so that when the output shaft of the motor rotates, the pull rope 3212 is wound around the traction wheel 3211, thereby converting the power of the rotation of the output shaft of the motor into traction force. At this time, the power has been transmitted to the second-stage transmission mechanism 322 by the pull rope 3212, causing the second-stage transmission mechanism 322 to be lowered or lifted, thereby converting the rotational motion into the lowering and lifting motion.

[0050] Of course, in other embodiments, the first-stage transmission mechanism 321 may also be a common transmission mechanism such as a gear rack transmission mechanism, a nut screw transmission mechanism, or a worm gear.

[0051] As a possible implementation, Figure 1 See also Figure 1-Figure 6 , the second-stage transmission mechanism 322 includes: a first slide rail 3222 and a first roller 3221. The first slide rail 3222 is arranged along the pulling direction of the washing body 2, and the rear end of the first slide rail 3222 (the end away from the pulling direction of the washing body 2) is connected to the pull rope 3212, and the front end of the first slide rail 3222 (the end facing the pulling direction of the washing body 2) is rotatably connected to the outer shell 1. The first roller 3221 is fixedly installed on the washing body 2 corresponding to the first slide rail 3222. Among them, the motor is configured to be installed in parallel above the rear end of the outer shell 1 through a motor bracket. Parallel installation means that the motor shaft is installed parallel to the outer shell 1. In this way, through the rotation of the output shaft of the motor connected to the outer shell 1, the pull rope 3212 drives the first slide rail 3222 connected to the outer shell 1 to perform lowering and lifting movements.

[0052] Then as Figure 2 See also Figure 1 as well as Figure 3-Figure 6The first roller 3221 and the first slide rail 3222 are configured such that when the first slide rail 3222 is lifted to the first preset position, the first slide rail 3222 abuts against the first roller 3221, and the first roller 3221 moves upward by a first preset distance under the support force of the first slide rail 3222, so that the washing body 2 is released from the fixed connection with the housing 1. In this way, the first roller 3221 and the first slide rail 3222 form a rolling connection, so that the washing body 2 slides on the first slide rail through the first roller 3221, so that the washing body 2 is pulled out or pushed back relative to the housing 1.

[0053] It should be noted that the first preset position is the highest position of the first slide rail 3222 when performing the lifting movement, and when the first slide rail 3222 is at the first preset position, the first slide rail 3222 abuts against the first roller 3221 and drives the first roller 3221 to move upward by a first preset distance. The first preset distance is the distance that the washing body 2 and the housing 1 are released from the fixed connection after the first roller 3221 moves upward by the first preset distance. Obviously, the size of the first preset distance can be determined according to specific needs, as long as the washing body 2 and the housing 1 can be released from the fixed connection.

[0054] Then as Figure 3 See also Figure 1 and Figure 2 as well as Figure 4-Figure 6 The first roller 3221 and the first slide rail 3222 are constructed so that when the first slide rail 3222 is lowered to the second preset position, the first slide rail 3222 and the first roller 3221 are disengaged from each other, so that the washing body 2 located inside the shell 1 is fixedly connected to the shell 1 under the action of its own gravity, so that the washing body 2 is embedded relative to the shell 1.

[0055] It should be noted that the second preset position is the lowest position of the first slide rail 3222 when it is descending, and when the first slide rail 3222 is located at the second preset position, the first slide rail 3222 and the first roller 3221 are separated from each other.

[0056] Furthermore, despite the above combination Figure 1-Figure 6The motor described is connected to the upper rear end of the housing 1 through a motor bracket, but this is not restrictive. Those skilled in the art can also connect the motor to the lower front end of the washing body 2 through a motor bracket as needed. Correspondingly, the first roller 3221 is fixedly connected to the upper front end of the housing 1. At this time, the first slide rail 3222 is rotatably connected to the upper part of the washing body 2 corresponding to the first roller 3221, so that the first slide rail 3222 can be driven by the motor to lift and lower, thereby realizing the contact and non-contact of the first slide rail 3222 and the first roller 3221, so as to realize the embedding or pulling out of the washing body 2 relative to the housing 1. Without departing from the basic principles of the present invention, those skilled in the art can flexibly select the connection position of the motor, the first slide rail 3222 and the first roller 3221 according to the specific application scenario, as long as it can be realized that the first slide rail 3222 is driven by the motor to lift or lower the first slide rail 3222 and the first roller 3221 contact and non-contact.

[0057] As a possible implementation, Figure 2 See also Figure 4 and Figure 6 , a second roller 22 is provided at the front end of the bottom of the washing body 2, a foot 21 is provided at the rear end of the bottom of the washing body 2, and a base is provided at a position corresponding to the foot 21 in the outer shell 1. When the washing body 2 is located at the embedded position relative to the outer shell 1, the first slide rail 3222 is driven by the traction wheel 3211 and the pull rope 3212 to descend. When the first slide rail 3222 is lowered to the second preset position, the first roller 3221 and the first slide rail 3222 are not in contact, and the foot 21 of the washing body 2 falls into the base of the outer shell 1 to achieve a fixed connection between the washing body 2 and the outer shell 1. Preferably, the foot 21 is made of rubber material, so that when the washing body 2 is fixedly connected to the outer shell 1 through the foot 21, the foot 21 and the outer shell 1 have a large friction force and also have the effect of eliminating the vibration between the washing body 2 and the outer shell 1, thereby avoiding the situation where the washing body 2 moves relative to the outer shell 1 due to its own vibration during the washing process.

[0058] It should be noted that although the above combination Figure 1 The bottom of the washing body 2 is described as being provided with a foot 21, but this is not restrictive. A person skilled in the art may, as needed, not provide the foot 21 at the bottom of the washing body 2, so that when the first slide rail 3222 is in the second preset position, the bottom of the washing body 2 is fixedly connected to the outer shell 1.

[0059] As a possible implementation, Figure 2 See also Figure 2-Figure 4 and Figure 6, the front end of the bottom of the washing body 2 is provided with a second roller 22 that is always in contact with the ground, the rear end of the bottom of the washing body 2 is provided with a foot 21, and a base is provided at a position corresponding to the foot 21 in the outer shell 1. When it is necessary to pull out the washing body 2 located in the embedded position, the first slide rail 3222 is lifted up under the drive of the pull rope 3212. When the first slide rail 3222 is lifted to the first preset position, the first roller 3221 abuts against the first slide rail 3222, and moves upward a first preset distance under the action of the first slide rail 3222. The foot 21 of the washing body 2 is detached from the base of the outer shell 1, and the second roller 22 is rollingly connected to the ground, so that the washing body 2 slides relative to the ground under the action of the first roller 3221 and the second roller 22, so that the washing body 2 can be pulled out from the inside of the outer shell 1. Moreover, through the above-mentioned setting method, when the washing body 2 is pulled out, the situation in which the second roller 22 slides out of the outer shell 1 or is pushed back into the inner shell 1, causing the roller to drop or rise and cause a sense of frustration, can be avoided. This ensures the smooth operation of the washing body 2 during the pulling out and pushing back process, thereby improving the user experience.

[0060] It should be noted that although the above combination Figure 2 The front end of the bottom of the washing body 2 is described to be provided with a second roller 22 that is always in contact with the ground, but this is not restrictive. Those skilled in the art can also set the second roller 22 on the end of the bottom of the washing body 2 corresponding to the outer shell 1 as needed, so that the bottom of the washing body 2 is slidably connected to the second roller 22.

[0061] As a possible implementation, Figure 1 See also Figure 2-Figure 6 The household appliance further includes a second slide rail 11, which is arranged along the direction of the washing body 2 to provide a movement guide for the washing body 2. Preferably, the second slide rail 11 is fixedly connected to the outer shell 1 by a fastener. And the second slide rail 11 is constructed as follows: the front end of the second slide rail 11 extends to the front end of the outer shell 1, and the rear end of the second slide rail 11 extends to the front end of the first slide rail 3222. The second slide rail 11 is also constructed as follows: when the first slide rail 3222 is lifted to the first preset position, the second slide rail 11 is docked with the first slide rail 3222 to form a slideway, so that the first roller 3221 rolls on the formed slideway, thereby pulling the washing body 2 out from the inside of the outer shell 1.

[0062] In addition, the inventors also discovered during the process of implementing the present invention that in the prior art, the rollers arranged at the front and rear ends of the washing body 2 are connected to the connecting rod of the lifting device, so that the rollers are driven down by the lowering of the connecting rod of the lifting device to achieve a sliding connection between the washing body 2 and the ground. During long-term use, the connecting rod of the lifting device will bend and deform, causing the washing body 2 to shake when being pulled out, and even causing the washing body 2 to be difficult to pull out.

[0063] The present invention fixes the first roller 3221 on the washing body 2 and the second slide rail 11 on the housing 1, so that the connection structure between the first roller 3221 and the washing body 2, and the second slide rail 11 and the housing 1 is simpler and has a better bearing capacity, so that the washing body 2 slides more stably on the second slide rail 11 through the first roller 3221, thereby improving the user experience.

[0064] It should be noted that although the above combination Figure 1 and Figure 2 The second slide rail 11 is described as being disposed above the outer shell 1, so that the first slide rail 3222 can dock with the second slide rail 11 to form a slideway when the first slide rail 3222 is in the first preset position, thereby enabling the washing body 2 to be pulled out or pushed back through the slideway formed by the docking of the first slide rail 3222 and the second slide rail 11. However, this is not restrictive, and those skilled in the art may also choose not to dispose the second slide rail 11 on the outer shell 1 as needed. In this case, one or more horizontally disposed first slide rails 3222 may be disposed above the outer shell 1, and the first slide rail 3222 is driven by a hydraulic cylinder to perform lifting and lowering movements relative to the outer shell 1, so that the roller at the bottom of the washing body 2 can contact or not contact the first slide rail 3222.

[0065] As a possible implementation, Figure 1 See also Figure 2-Figure 6 The household appliance also includes a limiting protrusion 12, which is arranged at the front end of the second slide rail 11, so that when the first roller 3221 installed at the bottom of the washing body 2 is pulled out along the second slide rail 11 following the washing body 2, the limiting protrusion 12 can prevent the first roller 3221 from sliding out from the front end of the second slide rail 11, thereby reducing the risk of the first roller 3221 sliding out from the front end of the second slide rail 11.

[0066] As a possible implementation, the household appliance further includes a position sensor (not shown), a prompter (shown in the figure) and a controller (not shown). The position sensor, the prompter, the controller and the drive transmission device 3 are respectively connected to the controller. The position sensor is used to detect the position of the first slide rail 3222 and send the detected position signal to the controller connected thereto, and the controller determines the position of the first slide rail 3222 according to the received position signal. When it is detected that the first slide rail 3222 is located at the first preset position, the controller controls the prompter to issue a prompt message that the first slide rail 3222 is located at the first preset position. When it is detected that the first slide rail 3222 is located at the second preset position, the controller controls the prompter to issue a prompt message that the first slide rail 3222 is located at the second preset position, so that the user can pull out the washing body 2 according to the prompt message issued by the prompter to avoid damage to the washing machine due to user's misoperation.

[0067] Preferably, the prompter is a plurality of LED lights arranged in a line. When it is detected that the first slide rail is located at the first preset position, the controller controls the plurality of LED lights to flash in sequence. When it is detected that the first slide rail is located at the second preset position and a position between the first preset position and the second preset position, the controller controls the plurality of LED lights to be half-lit. After a preset time, when it is detected that the first slide rail cannot reach the first preset position or the second preset position, the controller controls the plurality of LED lights to be all lit to issue a position error prompt so that the user can perform maintenance.
