The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
The invention relates to a clothes processing device, which comprises an inner barrel and a clothes identification device, wherein the clothes identification device comprises a signal identification transmitting end which can transmit an identification signal into the inner barrel, the identification signal forms an identification area, and clothes can be identified when being placed in the area.
The clothes identification device can identify clothes in a Radio Frequency Identification (RFID) mode, the clothes identification device comprises an RFID reader, electronic tags capable of being read by the RFID reader are arranged on the clothes, the RFID reader can generate electromagnetic waves with certain frequency to form an identification area, and the electronic tags in the area can be identified.
The electronic tag carries the information of the clothes, and the clothes processing equipment can select the processing program corresponding to the clothes according to the clothes information after acquiring the clothes information, so that the manual selection or manual parameter input by a user is not needed, the operation steps are simplified, and the processing process is more intelligent.
The laundry treating apparatus may be a washing machine, a dryer, or other devices for treating laundry, and the following description will be given of specific embodiments of the present invention by taking a pulsator type washing machine as an example.
The laundry treating apparatus includes an inner tub 2 having an opening above, into which laundry is introduced from the opening. An identification signal transmitting end 11 is arranged above the inner barrel and can transmit identification signals into the inner barrel, a radiation area A is formed in an area to which the identification signals are radiated, once an electronic tag is positioned in the radiation area A, the electronic tag can be sensed by a clothes identification device, and clothes information carried in the electronic tag can be acquired.
In one embodiment, in order to make the signal uniformly cover all areas in the barrel, the identification signal transmitting end can be arranged on the upper cover above the inner barrel, the identification signal is transmitted at the position of the upper cover corresponding to the center of the inner barrel bottom, a conical radiation area is integrally formed, and the conical shape can cover all positions of the inner barrel bottom, so that the clothes can be identified.
The height of the clothes placed in the inner barrel is possibly certain, the radiation area only covers the bottom of the inner barrel, and the highest position of the stacked clothes is also located in the radiation area to ensure that the clothes can be identified. The height that can hold the clothing in the inner bucket is h, the radiation area of identification signal transmitting end covers inner barrel height h department cross section at least to guarantee that the clothing can be discerned.
Since the electromagnetic wave signal can penetrate through the material such as plastic, when the material of the clothes treatment device, especially the material of the inner barrel, can be penetrated by the electromagnetic wave, the radiation area needs to cover the area in the inner barrel, and the condition that the radiation area is too large to cause the false recognition of the clothes outside the device also needs to be avoided.
Although the identification signal emitting end is arranged on the upper cover and has a uniform signal which can be distributed on the bottom of the inner barrel, the identification signal reflecting end is arranged on the upper cover, and a corresponding circuit needs to be additionally arranged, so that the cost of the clothes treatment equipment can be increased. The identification signal transmitting terminal may also be provided on the tray so as to be able to connect with the wiring in the tray.
In one embodiment, a tray seat is arranged above the inner barrel, a control panel 1 is arranged on one side of the tray seat, an identification signal transmitting end 11 is arranged on one side of the control panel 1 facing the inner barrel, and the sector areas are symmetrically distributed on two sides of a connecting line of the circle center of the bottom of the inner barrel and the identification signal reflecting end.
As shown in fig. 1-3, the tray is disposed above the inner barrel in a square frame shape, a control panel 1 is disposed on one side of the tray, an identification signal emitting end 11 may be disposed on the control panel 1, and fig. 3 is a schematic view of a side of the control panel facing the inner barrel, and the identification signal emitting end is disposed on a side of the control panel facing the inner barrel so as to emit a signal into the inner barrel. The signal emitted by the identification signal emitting end forms a three-dimensional radiation area, and the three-dimensional area can be in a cone shape or a pyramid shape. The radiation area is in a three-dimensional shape, but the part covering the bottom of the inner barrel can be regarded as a two-dimensional plane shape. The radiation area of the signal emitted by the identification signal emitting end at least covers any radius of the bottom of the inner barrel.
Further, the radiation area of the signal emitted by the identification signal emitting end at least covers a sector area of the bottom of the inner barrel; preferably, the central angle of the sector area is 90 degrees, and the sector area can cover one fourth of the area of the inner barrel. Since the entire radiation area may be a rectangular pyramid, when the bottom surface of the rectangular pyramid is square, the area covering the bottom of the inner tub is a sector having a central angle of 90 °. The central angle can also be 60 degrees, and the cover can cover one sixth area of the inner barrel, so that the signal intensity of each part is more uniform.
The identification signal transmitting end is arranged at a position closer to the inner barrel, so that the intensity of the identification signal can be higher, the identification signal transmitting end can be arranged at a position shown in figure 4 and is arranged at the middle position of the control panel, the identification signal transmitting end is close to the inner barrel, when the radiation area covers the inner barrel bottom in a quarter circle, the position covering the inner barrel bottom can be as shown in figure 4, the radiation area is symmetrically distributed at two sides of a connecting line between the circle center of the inner barrel and the identification signal transmitting end, the radiation intensity of the two sides is more equal, and when the identification signal transmitting end is matched with the inner barrel in a rotating mode, the covered area can be identified.
Since other components, such as the display 12 and the touch keys, need to be disposed on the control panel, for reasons of good appearance and convenience of operation, the display or the touch keys are usually disposed at the middle position of the control panel, and the identification signal transmitting end has to avoid the above components, therefore, the identification signal transmitting end cannot be disposed at the middle position, and needs to be disposed at a position deviated from the central line, as shown in fig. 5.
Similarly, the radiation areas are symmetrically distributed on two sides of a connecting line between the circle center of the inner barrel and the identification signal transmitting end, so that the radiation intensity of the two sides is relatively equal, and when the radiation areas are matched with the inner barrel in a rotating mode, the covered areas can be identified.
The height of the clothes placed in the inner barrel is possibly certain, the radiation area only covers the bottom of the inner barrel, and the highest position of the stacked clothes is also located in the radiation area to ensure that the clothes can be identified. The height that can hold the clothing in the inner bucket is h, and the radiation area of identification signal transmitting end covers a radius of inner barrel height h department's cross section at least, or a fan-shaped region to guarantee that the clothing can be discerned. The signal emitted by the identification signal emitting end is integrally conical, so that the covering area of the upper part of the inner barrel is smaller than that of the bottom of the inner barrel, and therefore, under the condition that the identification signal does not leak to the clothes processing device, the covering area above the inner barrel is ensured as much as possible, so that all clothes can be still identified when more clothes are left.
In order to reduce the area difference of the upper section and the lower section of the cone, the identification signal transmitting end can be set to be a larger transmitting surface, so that the upper coverage difference and the lower coverage difference of the inner barrel are reduced, and the clothes can be identified while the signals are prevented from leaking.
The arrangement of the mode can prevent the electromagnetic wave of the identification signal from penetrating through the inner barrel and other structures of the clothes treatment equipment, so that the electromagnetic wave is radiated to the outside of the clothes treatment equipment, and if the electronic tag is stored outside the clothes treatment equipment, the clothes identification device can identify the part of clothes, and the condition of error identification is caused.
However, since the electromagnetic wave can be reflected by the metal, it is possible to prevent the leakage of the identification signal by using this characteristic, the inner tub is made of a material capable of reflecting the identification signal, and the inner tub reflects the identification signal to form an irregular radiation region in the inner tub, and preferably, the inner tub is made of a metal material, and reflects the identification signal after contacting the inner tub, thereby forming a larger identification region in the inner tub, but since the upper portion of the inner tub has an opening, a signal shielding member should be provided at the opening or the upper cover to prevent the erroneous identification of the laundry other than the laundry treating apparatus.
The invention also relates to a control method of the clothes treatment equipment.
The clothes processing equipment is provided with a clothes identification program, and the clothes identification program at least comprises a control identification signal transmitting end for transmitting a signal and a control inner barrel for rotating.
The rotation angle of the inner barrel needs to have different identification periods according to different radiation areas. For example, when the radiation area of the signal emitted by the identification signal emitting end at least covers any radius of the bottom of the inner barrel, the clothes identification program controls the identification signal emitting end to emit the signal and controls the inner barrel to rotate for 360 degrees to serve as an identification period, so that the starting point and the end point of rotation are coincident, and clothes cannot be identified in a missing mode. When the radiation area of the signal emitted by the identification signal emitting end at least covers a sector area of the inner barrel bottom, the central angle of the sector is theta, the main control system controls the inner barrel to rotate 360 degrees to theta to serve as an identification period after the clothes identification device is started, and the inner barrel can identify all areas of the inner barrel bottom without rotating for one circle because the clothes in the theta angle range are identified.
However, due to the influence of the rotating speed of the inner barrel, unstable signals, interference of materials of clothes and the like, missed identification may exist in the clothes identification process, and the problem can be solved by controlling the inner barrel to rotate by at least two corresponding angles of identification periods through a clothes identification program, so that the interference of the factors can be reduced to the greatest extent in two or more periods, and the identification accuracy is improved.
Since there is a case that one piece of clothes is recognized several times in several periods, the repeatedly recognized clothes should be deleted in the clothes recognition process, and the control steps of the above process include:
step S1: recording all the electronic tags identified as a first set in a first identification period;
step S2: recording all the electronic tags identified as a second set in a second identification period;
step S3: and merging the first set and the second set, and deleting the repeated electronic tags to form a final set.
The above steps are only exemplified by two identification periods, when there are three identification periods, the first set, the second set, and the third set may be merged after all three identification periods are finished, and the duplicate electronic tags are deleted, or the first set and the second set may be merged after two periods, and after the duplicate electronic tags are deleted, a new set is formed, and the new set is merged with the third set again, and the duplicate electronic tags are deleted, so as to form a final set.
As shown in fig. 6, there may be a case where the recognition results are consistent due to the same positions of the laundry in the two recognition periods, and the inner tub and the pulsator may rotate relatively to each other to move the positions of the laundry, and specifically, the pulsator is disposed at the bottom of the inner tub, and the inner tub and the pulsator may rotate synchronously/relatively to each other, and the control process of the laundry recognition program includes controlling the pulsator and the inner tub to rotate synchronously in the recognition periods, and controlling the pulsator and the inner tub to rotate relatively between the two recognition periods to adjust the positions of the laundry.
The rotating speed of the inner barrel may affect the accuracy of the identification process, so that the rotating speed of the inner barrel is not too large when the inner barrel rotates, the condition that all clothes cannot be identified due to too short identification time is prevented, but the inner barrel still needs a certain rotating speed to improve the identification time in order to improve the efficiency.
The information of all clothings in can discerning the interior bucket to the discernment of clothing can also judge the clothing quantity, through the quantity of judgement clothing, reminds the user whether take out all clothings to the in-process of preventing to get the clothing produces the omission.
The radiation area of the signal emitted by the identification signal emitting end at least covers any radius of the bottom of the inner barrel, and through the cooperation of the radiation area and the rotation of the inner barrel, all positions of the bottom of the inner barrel can be identified when the inner barrel rotates for a certain angle, so that clothes are prevented from being missed; the position that the radiation area set up according to the identification signal transmitting terminal has different setting methods, forms reasonable radiation area, can guarantee that the signal strength of each position has less difference in the radiation area, prevents that the corner position from omitting because the weak production of signal strength, and prevents that the radiation area is too big to the outside clothing misidentification of organism.
