Description

Laundry Disposal Equipment {LAUNDRY TREATING APPARATUS}

The present invention relates to a laundry treating apparatus having a motion sensor which is introduced into a rotating drum and detects its own motion caused by the rotation of the drum.

Laundry treatment equipment is a device that processes the laundry through a variety of actions, such as washing, dehydration and / or drying. The laundry treatment machine uses a water and detergent to remove the dirt on the laundry (hereinafter also referred to as “foam”), and a drum that spins the wet laundry into the drum at high speed so that the dehydrator and the laundry are dehydrated. There is a dryer for drying the laundry by supplying the drying air into the input drum, a combined drying washing machine having a drying function and a washing function.

In general, a laundry treatment machine includes a drum into which a cloth is put, and the drum is rotated by a driving unit. Depending on the amount of cloth loaded into the drum, the load on the drive unit varies. Therefore, the load applied to the drive unit is sensed and the amount of fire (or the weight of the gun) is estimated based on this, and the operation setting of the device (for example, water supply amount, rotational speed of the drive unit, dehydration time, etc.) according to the amount of discharge Decided.

However, the amount obtained in this way is a value reflecting the weight (weight) of the fabric, not the value indicating the volume of the fabric. That is, in some cases, since there are light or bulky fabrics, and on the contrary, heavy or small grapes, the method of estimating the volume based on the quantity is not accurate.

Meanwhile, Korean Patent Laid-Open Publication No. KR1999-0062394 (published Jul. 26, 1999) discloses a method for determining the quality of a material. However, the quality of the fabric here is based on the ability of the fabric to hold water, and it is possible to estimate whether the material of the fabric is high or low in moisture, but it does not give accurate information about the volume of the fabric. In addition, since the driving of the drum required to obtain the dry amount and the dry amount is carried out before and after water supply, there is a problem that the total operating time is increased. In addition, since water supply is essential for determining the quality of the foam, there is a limit that cannot be applied to a dryer.

The problem to be solved by the present invention is, firstly, to provide a laundry treatment apparatus capable of obtaining accurate information about the volume (or quality) of the laundry put into the drum.

Second, to provide a laundry treatment apparatus that can be transmitted to the control unit for controlling the overall operation of the laundry treatment machine, the motion information sensed by the motion detector put into the drum.

Third, it is to provide a laundry treatment apparatus capable of distinguishing between a relatively large and small bag and a small but bulky bag.

A first wireless communication module positioned and fixedly disposed with respect to the casing, and a motion detector that is introduced into the drum and moves in accordance with the rotation of the drum.

The motion detector, a motion recognition sensor for detecting its own movement caused by the rotation of the drum, and wirelessly communicates with the first wireless communication module, and the information on the motion detected through the motion recognition sensor A second wireless communication module for transmitting to the first wireless communication module, and a power supply for supplying power to the motion recognition sensor and the second wireless communication module.

In the laundry treatment machine of the present invention, first, by directly detecting the remaining space in the drum (space not filled) depending on the volume of the fabric using a motion detector, it is possible to accurately measure the volume of the drum in the drum There is. In particular, in the prior art by measuring the volume of the cloth in an indirect manner based on the amount of water (weight of the cloth), or the water level change according to the moisture content of the cloth, the accuracy is reduced, the present invention directly detects the space distribution in the drum Because the accuracy is high.

Second, even with the same weight, it is possible to distinguish between a relatively bulky fabric and a small fabric. Therefore, based on this, it is possible to design a more improved washing course considering the weight as well as the weight of the fabric, there is an effect that the washing performance is improved, the power consumption is reduced.

Third, even in the case of a large cloth, if the volume is small, a small amount of water and detergent can be added compared to the conventional, there is an effect that can reduce the water consumption and detergent usage.

Fourth, the present invention can detect the volume of the fabric without detecting the amount of wet bubble or change in water level, there is an effect that can be applied to the dryer.

Fifth, the motion detector is applied to a conventional laundry treatment apparatus having a communication function, and the program of the laundry treatment apparatus is updated to implement a course setting in consideration of the volume of the cloth.

Although not necessarily limited thereto, the housing 270 may have a spherical shape. The housing 270 may include a first housing member 271 and a second housing member 272, each of which has a half spherical shell shape. The first housing member 271 and the second housing member 272 are coupled to each other to form a spherical shape, and the motion recognition sensor 210 in a space defined by the first housing member 271 and the second housing member 272. ), The second wireless communication module 220 and the power source 260 may be accommodated.

The second housing member 272 may be formed with a ring-shaped coupling rim 272a along a circumferential open side of the hemisphere. The first housing member 271 may have a coupling groove 271a corresponding to the coupling rim 272a along a circumference of an open one side of the hemispherical angle.

More specifically, when the volume of the cloth injected into the drum 32 is large (see FIG. 4A), when the volume of the cloth injected into the drum 32 is small (see FIG. 4B). In comparison, there is a large amount of free space (ie, a non-foamed space) in which the motion detector 200 can be moved within the drum 32. Therefore, the signal output by the motion recognition sensor 210 is different according to the volume of the cloth injected into the drum 32, and the first controller 130 is loaded into the drum 32 based on the signal. The volume of or the amount of free space in the drum 32 can be estimated.

On the other hand, the first control unit 130 may further control the drive unit 38 for detecting the amount of dose. At this time, the detected quantity is estimated based on the principle that the load acting on the driving unit 38 varies according to the inertia of the cloth injected into the drum 32. For example, in the process of accelerating the drum 32 in the stationary state to rotate, it corresponds to the load acting on the drive unit 38 when lifted by the carriage lifter 51 positioned at the lowest point of the drum 32. To obtain a quantity based on the current value output from the drive unit 38 or the time taken until the rotation of the drum 32 reaches a predetermined angle, or alternatively, to brake the drum 32 being rotated at a constant speed. And, in this process can be obtained based on the current value output from the drive unit 38, or the time it takes until the drum 32 is stopped, in addition to the various methods for obtaining the dose in the washing machine art Of course, it is also possible to use these known techniques.

Either way, the principle of calculating the quantity is based on the weight or inertia of the gun, which does not accurately reflect the volume of the gun. On the contrary, in the present invention, the first controller 130 may determine the state of the fabric more accurately by further considering the information obtained through the motion recognition sensor 210 together with the amount of the dose.

The battery may be a disposable battery (or a primary battery) or a rechargeable secondary battery. In the case of the secondary battery, the battery may be a nickel cadmium battery, a nickel hydride battery, a lithium ion battery or a lithium polymer battery.

The housing 270 may be provided with a charging terminal connected to an external power source for charging the battery. In addition, the battery may be separated from the housing 270 by the user, and then charged by a separate charger or replaced by another battery.

The motion detector 200 may further include a power switch 250. By the user operating the power switch 250, power may be supplied from the power supply 260 to the second control unit 230, the second communication module 220, and the motion recognition sensor 210.

The operation unit 240 is a switch for turning on or off the operation of the motion recognition sensor 210, and the user may operate the operation unit 240 to turn on or off the motion recognition sensor 210. However, when the motion recognition sensor 210 is also configured to be turned on / off according to the on / off operation of the power switch 250, the power switch 250 also functions as the operation unit 240. In this case, the operation unit ( 240 may be omitted.
