Description

TECHNICAL FIELD [0001] The present invention relates to a touch input means and a sink food waste dehydration apparatus including the touch input means.

The present invention relates to touch input means and a sink food waste dewatering device including the touch input means. More particularly, the present invention relates to touch input means that is supported by a drain port of a sink and can separate water from food waste using centrifugal force, The present invention relates to a garbage dewatering apparatus.

Food waste generated in the process of cooking, etc., when landfilled, causes leachate and causes soil and water pollution. If incinerated together with general garbage, it causes dioxin emission in the atmosphere. Therefore, separate from other general garbage And is collected and processed separately.

In general households, the food waste filtered by the filter in the sink is collected in a plastic container with a lid and collected in a food garbage bag or a food garbage collecting box used for collecting.

However, in the process of moving food waste, dirt may fall on the floor, and the indoor environment may become poor due to odor and hygiene.

As a method for reducing inconvenience related to the treatment of such wet food garbage, a food garbage dewatering device has been developed which removes moisture to some extent and empties the food waste before the empty food waste in the sink is emptied.

However, the conventional food garbage dewatering apparatus has a problem in that a high output motor incorporated in a sink is used in the case of an electric type, and a manufacturing cost is increased because a complicated gear is used in a manual type.

In addition, the dewatering device used independently in the sink is not a coupling type, but a high output motor or a gear is used in many cases. When the dewatering device is used for a long period of time,

In addition, when the user directly dehydrates the food waste by rotating the dewatering device, it is inconvenient and cumbersome.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily carry out the present invention.

FIG. 1 is a perspective view of a kitchen garbage dewatering apparatus according to an embodiment of the present invention, and FIG. 2 is an exploded view of main components of a kitchen garbage dewatering apparatus according to an embodiment of the present invention.

As shown in Figs. 1 and 2, the sink garbage dewatering device can be largely composed of a support 1, a sieve 2, a rotating means 3, and a main body 4.

The support base 1 is supported by a drain hole of the sink and is provided at its upper side with a support base flange 11 fixed to the drain hole and a support member 12 extending downwardly around the support base flange 11.

The screen 2 is rotatably mounted on a support 1 and is connected to a screening flange 21 which engages with a rotating disk 31 to be described later and a screening flange 21 to filter food waste, A plurality of water supply holes 22 are provided. A plurality of support protrusions 211 spaced apart in the circumferential direction of the inner wall are formed in the filtering flange 21.

The rotating means 3 includes a rotating disk 31 which is coupled with the filtering net 2 to rotate the filtering net 2, a rotating shaft 32 which is rotatable in combination with the rotating disk 31, And a power member (33) for transmitting a rotational force to the driven member (31).

The rotary disc 31 has a plurality of coupling protrusions 311 formed on the outer wall of the rotary disc 31 so that the support protrusions 211 of the sieve 2 can be caught. The number of the engagement protrusions 311 may be appropriately formed corresponding to the number of the support protrusions 211 of the sieve 2.

The rotating shaft 32 is connected to the power member 33 and serves to transmit the rotational force of the power member 33 to the rotating disk 31.

The power member 33 may be a motor that generates a rotational force on the rotating shaft 32 when the power is supplied.

The main body 4 mainly comprises a housing 41, a cover 42, and a touch input means 43.

The housing 41 includes a power member 33 and a replaceable power source 34 for supplying power to the power member 33. [ Here, a battery or the like may be used as the electric power supply source 34.

The cover 42 is provided on the upper portion of the housing 41. A touch switch pattern 421 is formed at the center of the outer surface and a conductive pattern 422 is formed at the inner edge.

FIG. 3 is a block diagram of a touch input unit according to an embodiment of the present invention, and FIG. 4 is an exemplary view showing first and second positions according to an embodiment of the present invention.

3 and 4, the touch input unit 43 senses a touch at a predetermined position of the cover 42 and controls the rotation unit 3 according to the sensed touch signal. More specifically, The first sensor unit 431, the second sensor unit 432, and the control unit 433.

The first sensor unit 431 senses the touch of the cover 42 at the first position P1 and transmits the sensed first touch signal to the controller 433. [ The first position P1 may correspond to the touch switch pattern 421 of the cover 42 and may be the center of the cover 42. [

More specifically, the first sensor unit 431 can sense a touch with respect to the first position P1 using a capacitive method. 2, the first sensor unit 431 includes a first elastic body 4311a provided corresponding to the first position P1 of the cover 42 and a second elastic body 4311b surrounding at least one surface of the first elastic body 4311a And a first EMI gasket 4311 having a first conductive sheet 4311b. The first elastic body 4311a may be made of polyurethane, cotton or styrofoam.

That is, when a part of the user's body (for example, a finger) approaches or touches the touch switch pattern 421 of the cover 42, that is, the first position P1, virtual ground so that the electrostatic capacitance between the first position P1 and the first conductive sheet 4311b can be varied. Then, the level of the output signal is varied by the difference between the change value of the variable capacitance and the set value, so that the touch can be detected.

The second sensor unit 432 senses a touch to the second position P2 spaced from the first position P1 of the cover 42 by a predetermined distance and transmits the sensed second touch signal to the control unit 433 have. The second position P2 may correspond to the conductive pattern 422 formed on the inner peripheral edge of the cover 42 and may be in the form of a closed curve surrounding the first position. In this case, the closed curve form may include a partially closed form in which both ends of a single curve coincide with each other, and a partially opened form.

The second sensor unit 432 includes a second EMI 432 having a second elastic member 4321a disposed under the conductive pattern 422 and a second conductive sheet 4321b surrounding at least one surface of the second elastic member 4321a, And a gasket 4321. The second elastic member 4321a may be made of polyurethane, cotton or styrofoam, and the second EMI gasket 4321 may be provided on the entire lower portion of the conductive pattern 422 or on a part of the lower portion.

Thus, when the user's finger touches or approaches the second position P2 of the cover 42 (i.e., the conductive pattern 422), the electrostatic charge between the second position P2 and the second conductive sheet 4321b The capacitance can be varied, and the level of the output signal can be changed accordingly, so that the touch can be detected.

The control unit 433 can control the rotation means 3 according to the touch signal detected only when a touch to the first position P1 is detected.

More specifically, when the touch is sensed at both the first position P1 and the second position P2 or when the touch is sensed only at the second position P2, the control unit 433 skips the sensed touch signal and controls the rotation means 3 to operate according to the first touch signal detected only when the touch is sensed at the first position P1. At this time, the first touch signal sensed at the first position P1 is a user-intended signal generated by the user touching or approaching the first position P1, and is sensed at the second position P2 The second touch signal is a user-unintended signal generated by an action of water falling or flowing in the second position P2.

That is, when the touch input means 43 operates in the electrostatic capacity mode, the rotation means 3 may malfunction due to moisture. Particularly, when the touch input means 43 is in a space using water such as a sink, A two point sensing method of detecting a touch at the first position P1 and the second position P2 may be used because the rotating means 3 may malfunction due to water drop or flow. When the touch is sensed only at the first position P1, the operation of the rotation means 3 is controlled according to the sensed touch signal. Otherwise, if the sensed touch is detected, It is possible to prevent the rotating means 3 from malfunctioning due to an unintended signal.

In this manner, when the touch is detected only at the first position P1 without touching the second position P2, the control unit 433 determines that the user desires to dehydrate or stop the touch The operation of the rotating means 3 can be controlled.

If the touch is not detected for a predetermined time, the control unit 433 enters the standby mode and can release the standby mode and switch to the operation mode only when a touch to the first position P1 is detected. That is, if the touch is not detected for a predetermined time, the controller 433 enters the other components except for itself into the standby mode. Then, the controller 433 wakes-up if a touch signal is sensed. If a touch to the first position P1 is sensed, the controller 433 cancels the standby mode and switches to the operation mode, The touch signal is skipped and a standby mode can be maintained. In this way, the controller 433 normally operates in a standby mode that does not consume power from the power source 34, and operates in an operation mode that consumes power from the power source 34 if necessary, thereby reducing unnecessary energy consumption I will.

In addition, the controller 433 determines whether a touch to the second position P2 is detected within a predetermined time when a touch to the first position P1 is detected. That is, the controller 433 makes a difference between the time at which the touch is sensed at the first position P1 and the time at which the touch is sensed at the second position P2 so that the touch can be detected more accurately. For example, there may be a delay in the time from when the water falls or flows on the cover 42 until it is detected by the touch input means 43. Therefore, the control unit 433 detects when the user touched the water, So that more accurate touch detection results at the first and second positions P1 and P2 can be obtained.

5 shows an exemplary view showing first and second positions according to another embodiment of the present invention.

5, the first position is composed of a plurality of (first-first position P11) to first-N positions P1N, and the second position P2 corresponding to the conductive pattern 422 is And a plurality of cell shapes for dividing the plurality of first positions P11 to P1N.

For example, the plurality of first positions may be composed of a first position P11, a first position P12, a third position P13, and a fourth position P14, The control unit 433 controls the touch of any one of the first position P11, the 1-2 position P12, the 1-3 position P13, and the 1-4 position P14, The operation of the rotation means 3 can be controlled according to the first touch signal detected. At this time, if the second touch signal detected at the second position P2 comes in with the first touch signal or only the second touch signal is received, the user determines that the second touch signal is not the intended signal, P11 to P14, the operation of the rotating means 3 can be controlled using only one of the first touch signals detected. Here, the number of the first EMI gaskets may be appropriately formed corresponding to the number of the first positions, and the number of the second EMI gaskets may be appropriately formed corresponding to the shapes of the conductive patterns 422.

In this manner, the number and shape of the first and second positions are appropriately changed according to the intended use, and the touch input means can be manufactured in various forms.

The configuration of the touch input means is not limited to the kitchen garbage dewatering device, and can be applied to various means including a touch input cover.

Hereinafter, a description will be given of the operation (action) method of the present embodiment of the food waste dewatering apparatus.

First, when the user's finger approaches the first position P1, the first sensor unit 431 senses a touch on the first position and transmits the first touch signal to the controller 433. [ Here, the first touch signal is a signal for operating the dewatering device, and the controller 433 controls the power source 34 to supply power to the power member 33 according to the first touch signal, . Then, the power member 33 is operated to rotate the rotating shaft 32, and the rotating disk 31 rotates together with the rotating member.

As a result, the water in the food waste inside the sieve 2 is drawn out of the sieve 2 due to the centrifugal force.

When the user's finger approaches the first position P1 again, the first sensor unit 431 senses the touch with respect to the first position P1 and transmits the first touch signal to the control unit 433. Here, the first touch signal is a signal for stopping the dewatering device, and the control unit 433 controls the power supplied from the power source 34 to the power member 33 to be cut off according to the first touch signal, 3) can be stopped. Then, the power member 33 is stopped, and the rotating shaft 32 and the rotating disk 31 are also stopped in conjunction with the rotating shaft 32.

While the present invention has been particularly shown and described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, And all changes and modifications to the scope of the invention.
