Shoe washing device

Abstract

The invention belongs to the field of washing, and particularly relates to a shoe washing device. The invention aims to solve the problem that when a shoe washing machine with a shallower washing barrel is used for washing, washed shoes are easily clamped between an impeller and a balance ring. The shoe washing device comprises a washing barrel, a driving part arranged outside the washing barrel, an impeller arranged inside the washing barrel and a balance ring fixedly arranged at the top of the washing barrel. The output end of the driving part is in transmission connection with the impeller and used for driving the impeller to rotate. The shoe washing device further comprises an impeller rotation detector, the impeller rotation detector is used for detecting resistance borne by the impeller during rotation, and when it is detected that the resistance is larger than a preset value, the driving part is controlled to drive the impeller to rotate reversely. When the impeller rotation detector detects that the resistance borne by the impeller during rotation is larger than the preset value, the driving part is controlled to drive the impeller to rotate reversely, and therefore the situation that the impeller and the balance ring jointly apply extrusion force to shoes, and consequently the shoes are damaged is avoided.

[0036] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. Those skilled in the art can make adjustments to them as needed to adapt to specific application scenarios.

[0037] For example, although the specification describes the impeller rotation detector as a torque sensor, the present invention can obviously adopt other similar means, such as the impeller rotation detector as an angle sensor, etc., as long as the impeller rotation detector can detect the resistance encountered by the impeller when it rotates.

[0038] It should be noted that, in the description of the present invention, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0039] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation", "setting", etc. should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, etc. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] In order to solve the problem that in a shoe washing machine with a shallow washing tub, washed shoes are easily stuck between the impeller and the balance ring during washing, which not only affects the washing effect but also causes damage to the shoes, the present invention provides a shoe washing device.

[0041] like Figure 1-2 As shown, the shoe washing device includes a washing tub 1, a driving member 4 (the driving member 4 in this embodiment is a rotating motor) arranged outside the washing tub 1, a impeller 2 arranged inside the washing tub 1 and a balance ring 3 fixedly arranged on the top of the washing tub 1; the output end of the driving member 4 is transmission-connected with the impeller 2 for driving the impeller 2 to rotate; the shoe washing device also includes a impeller rotation detector 5, which is used to detect the resistance encountered by the impeller 2 when it rotates. When it is detected that the resistance is greater than a preset value, the driving member 4 is controlled to drive the impeller 2 to reverse (i.e., rotate in the opposite direction of the current rotation direction).

[0042] The impeller rotation detector 5 and the driving member 4 are respectively connected to the controller (not shown in the figure) of the shoe washing device for communication. Specifically, the impeller rotation detector 5 is a torque sensor, which is arranged at the output end of the driving member 4 or the connecting shaft of the impeller 2. When the shoes are stuck between the impeller 2 and the balance ring 3, the two ends of the shoes will be squeezed by the impeller 2 and the balance ring 3, which may easily cause damage to the shoes. When the shoes are stuck, the impeller 2 is greatly hindered, so that when the torque sensor detects that the resistance is greater than the preset value, the driving member 4 is controlled to rotate the impeller 2 in the opposite direction relative to the original rotation direction, thereby effectively avoiding damage to the shoes.

[0043] To sum up, when washing shoes, the shoe washing device of the present invention detects the resistance encountered during rotation through the impeller rotation detector 5. When the shoes are stuck between the impeller 2 and the balance ring 3, in order to avoid damage to the shoes due to the impeller 2 continuing to rotate in the original manner, the shoe washing device of the present invention can control the driving part 4 to drive the impeller 2 to reverse when the impeller rotation detector 5 detects that the resistance encountered during rotation of the impeller 2 is greater than a preset value, thereby avoiding damage to the shoes due to the extrusion force applied to the shoes by the impeller 2 and the balance ring 3.

[0044] It should be noted that the above embodiments are only used to illustrate the principles of the present invention and are not used to limit the scope of protection of the present invention. Without departing from the principles of the present invention, those skilled in the art can adjust the above structures through other replaceable implementations so that the present invention can be applied to more specific application scenarios. These do not deviate from the principles of the present invention and therefore will fall within the scope of protection of the present invention.

[0045] For example, in an alternative embodiment, the driving member 4 in the embodiment before the structural adjustment may be replaced by a rotating motor:

[0046] The driving member 4 includes a linear drive, a pulsator gear (not shown in the figure) fixedly connected to the pulsator 2, and a rack (not shown in the figure) transmission-connected to the pulsator gear. The linear drive is a linear motor, a cylinder, a hydraulic cylinder or an electric push rod, etc., and the output end of the linear drive is fixedly connected to the rack. The rack is driven to move by the linear drive, and at the same time, the rack causes the pulsator gear to drive the pulsator 2 to rotate, thereby achieving washing.

[0047] This embodiment can also control the driving member to drive the impeller to reverse when the impeller rotation detector detects that the resistance of the impeller during rotation is greater than a preset value, thereby avoiding the situation where the impeller and the balance ring jointly apply a squeezing force to the shoes, causing damage to the shoes. These do not deviate from the principles of the present invention, and therefore will fall within the scope of protection of the present invention.

[0048] For example, in another alternative embodiment, the impeller rotation detector 5 recorded in the embodiment before the structural adjustment can also be replaced by a torque sensor, and the torque sensor is arranged at the output end of the driving member 4 or the connecting shaft of the impeller 2, and is replaced by:

[0049] The impeller rotation detector 5 is an angle sensor, which is arranged at the output end of the driving member 4 or the connecting shaft of the impeller 2 (not shown in the figure). Specifically, it is possible to determine whether the impeller is obstructed based on the rotation of the impeller detected by the angle sensor in the same time. When a shoe is stuck between the impeller 2 and the balance ring 3, the rotation angle of the impeller 2 in the same time becomes smaller, which can be used to determine the resistance of the impeller 2.

[0050] This embodiment can also control the driving member to drive the impeller to reverse when the impeller rotation detector detects that the resistance of the impeller during rotation is greater than a preset value, thereby avoiding the situation where the impeller and the balance ring jointly apply a squeezing force to the shoes, causing damage to the shoes. These do not deviate from the principles of the present invention, and therefore will fall within the scope of protection of the present invention.

[0051] For example, in another alternative embodiment, the impeller rotation detector 5 recorded in the embodiment before the structural adjustment can also be replaced by a torque sensor, and the torque sensor is arranged at the output end of the driving member 4 or the connecting shaft of the impeller 2, and is replaced by:

[0052] The impeller rotation detector 5 includes a magnet (not shown in the figure) and a magnetic induction sensor (not shown in the figure, the magnetic induction sensor can be a Hall sensor or a magnetoresistive sensor or other structures). The magnet is set at one of the first position of the impeller 2 and the second position inside the washing tub 1, and the magnetic induction sensor is set at another position.

[0053] Specifically, the first position may be the bottom of the impeller 2, and correspondingly, the second position may be the inner bottom of the washing tub 1. Alternatively, the first position may be the side wall or top of the impeller 2, and correspondingly, the second position may be the inner wall of the washing tub 1. The magnet and the magnetic induction sensor are arranged such that as the driving member 4 drives the impeller 2 to rotate, the magnet can approach and move away from the magnetic induction sensor, and when the magnet approaches the magnetic induction sensor, the magnetic induction sensor can feed back a signal to the driving member 4.

[0054] This embodiment can determine whether the impeller is obstructed based on the rotation of the impeller detected by the magnetic induction sensor in the same time. When a shoe is stuck between the impeller 2 and the balance ring 3, the number of times the magnet passes by the magnetic induction sensor in the same time is reduced, which can be used to determine the resistance of the impeller 2.

[0055] This embodiment can also control the driving member to drive the impeller to reverse when the impeller rotation detector detects that the resistance encountered by the impeller during rotation is greater than a preset value, thereby avoiding damage to the shoes due to the squeezing force applied by the impeller and the balance ring on the shoes.

[0056] These do not deviate from the principles of the present invention and therefore will fall within the protection scope of the present invention.

[0057] For example, in another alternative implementation, based on the structure recorded in the above embodiment before the structural adjustment, further:

[0058] A ball brush (not shown) is fixedly arranged on the top of the impeller 2. This embodiment can further improve the washing effect on shoes. These do not deviate from the principle of the present invention, and therefore will fall within the scope of protection of the present invention.

[0059] For example, in another alternative implementation, based on the structure recorded in the above embodiment before the structural adjustment, further:

[0060] A brush (not shown) is fixedly arranged on the inner wall of the washing bucket 1. This embodiment can further improve the washing effect of the shoes. These do not deviate from the principle of the present invention, and therefore will fall within the scope of protection of the present invention.

[0061] For example, in another alternative embodiment, the pulsator rotation detector 5 and the driving member 4 described in the above embodiment before the structural adjustment can be respectively connected to the controller of the shoe washing device for communication, and replaced by:

[0062] The shoe washing device further includes a wireless transceiver (not shown in the figure), and the pulsator rotation detector 5 and the driving member 4 are respectively connected to the external controller (in this embodiment, the external controller may be a server, a mobile phone, a smart speaker or a computer, etc.) through the wireless transceiver (in this embodiment, the wireless transceiver may be a Bluetooth transceiver or a WiFi transceiver). These do not deviate from the principles of the present invention, and therefore will fall within the scope of protection of the present invention.

[0063] For example, in another alternative embodiment, the pulsator rotation detector 5 and the driving member 4 described in the above embodiment before the structural adjustment can be respectively connected to the controller of the shoe washing device for communication, and replaced by:

[0064] The shoe washing device can also be connected to an external controller (in this embodiment, the external controller can be a server, a computer, etc., or a smart speaker, a specially designed small controller, etc.) by wired connection. These do not deviate from the principles of the present invention, and therefore will fall within the scope of protection of the present invention.

[0065] For example, in another alternative implementation, based on the above structure, further:

[0066] like Figure 3 As shown, a guide air bag 7 is provided at the bottom of the balance ring 3. An air pump 8 is also provided on the outside of the washing tub 1, and the output end of the air pump 8 is connected to the guide air bag 7; an air release valve (not shown in the figure) is also provided on the guide air bag 7. Figure 3 In the embodiment, the guide airbag 7 is in an inflated state.

[0067] In this embodiment, the number of air pumps 8 can be two or more (not shown in the figure), and the multiple air pumps 8 are evenly distributed. Of course, the number of air pumps 8 can also be one (not shown in the figure). In this case, in order to keep the washing tub 1 balanced during the dehydration rotation, a balance block (not shown in the figure) with the same weight as the air pump 8 can be set at a position symmetrical to the air pump 8 in the washing tub 1.

[0068] In order to obtain a good washing effect, the shoe washing device usually rotates the impeller 2 in forward and reverse directions under the control of the washing program, which can more fully improve the effect of washing shoes and allow the washing liquid to more fully contact different positions of the shoes.

[0069] In the structure of the implementation method before replacement, since the shoes are relatively easy to get stuck between the impeller and the balance ring, in order to avoid the shoes from being damaged due to the impeller continuing to rotate in the original manner, when the impeller rotation detector detects that the resistance encountered by the impeller during rotation is greater than a preset value, the driving member can be controlled to drive the impeller to reverse, thereby avoiding the situation where the impeller and the balance ring jointly apply a squeezing force to the shoes and cause the shoes to be damaged. Although the structure of the implementation method before replacement does achieve the situation where the shoes are squeezed and damaged, it will disrupt the original washing process of the washing program, which is equivalent to forcing the impeller 2 to change its original rotation direction in advance, which will affect the overall washing effect to a certain extent and there is a possibility of extending the washing time.

[0070] In this embodiment, by providing the guide airbag 7, the air pump 8 and the deflation valve, the guide airbag 7 is inflated to form a guide surface between the surface of the guide airbag 7 and the side of the balance ring 3, so that when the shoes are acted upon by the impeller 2 and the guide airbag 7, the shoes can slide upward along the guide airbag 7 to avoid being squeezed and damaged. Specifically, the guide airbag 7 can be inflated before or at the beginning of washing, and the guide airbag 7 can be deflated after washing. Thus, this embodiment can reduce the number of times that the impeller 2 changes its original rotation direction in advance. Of course, since there is still a possibility that the shoes are squeezed and stuck by the impeller 2 and the guide airbag 7 due to various reasons, this embodiment can control the driving member 4 to drive the impeller 2 to reverse when the impeller rotation detector 5 detects that the resistance encountered by the impeller 2 when rotating is greater than a preset value. These do not deviate from the principle of the present invention, and therefore will fall within the scope of protection of the present invention.

[0071] For example, in another alternative embodiment, based on the structure described in the previous alternative embodiment, further:

[0072] The impeller rotation detector 5 can feed back the resistance encountered by the impeller 2 when it rotates to the air pump 8; the impeller rotation detector 5, the air pump 8 and the air release valve are all communicatively connected with the controller (the controller can be the controller provided by the shoe washing device, or it can be an external controller, the external controller can be a server, a computer, etc., or it can be a smart speaker, a specially designed small controller, etc.).

[0073] In this embodiment, since the guide airbag 7 also occupies the space inside the washing tub 1 to a certain extent, when the shoes are not stuck and rotate in the washing tub 1, the guide airbag 7 will have a certain obstruction on the washing effect. Therefore, this embodiment controls the inflation and deflation of the guide airbag 7 through the feedback of the impeller rotation detector 5. When the impeller rotation detector 5 detects that the resistance encountered by the impeller 2 when rotating rises to a value close to the preset value, the guide airbag 7 can be inflated in advance, and when the impeller rotation detector 5 detects that the resistance encountered by the impeller 2 when rotating decreases, the guide airbag 7 can be deflated. A better washing effect and the effect of preventing shoes from being squeezed are achieved. These do not deviate from the principles of the present invention, and therefore will fall within the scope of protection of the present invention.

[0074] Those skilled in the art can understand that the above-mentioned shoe washing device also includes some other well-known structures, such as a processor, a controller, a memory, etc., wherein the memory includes but is not limited to a random access memory, a flash memory, a read-only memory, a programmable read-only memory, a volatile memory, a non-volatile memory, a serial memory, a parallel memory or a register, etc., and the processor includes but is not limited to a CPLD / FPGA, a DSP, an ARM processor, a MIPS processor, etc. In order to unnecessarily obscure the embodiments of the present invention, these well-known structures are not shown in the drawings.

[0075] Of course, the above-mentioned replaceable embodiments, as well as the replaceable embodiments and the preferred embodiments, can be used in a cross-coordinated manner to combine new embodiments to be suitable for more specific application scenarios.
