The present invention relates to a dishwasher, and more particularly, to a rinse feeding apparatus for introducing a rinse in a dishwasher.

Recently, as daily life becomes more complicated and women have more social involvement, the spread of dishwashers has been spreading to reduce household chores.

Typically, the dishwasher washes the dishes by sequentially performing a series of washing / rinsing / drying strokes as the user sets the time / count / water temperature.

An example of a conventional dish washer will be described with reference to FIG. 1.

The conventional dishwasher includes a main body 2 having a front open and a tub 4 installed therein, a door 6 having a lower end hinged at a front surface of the main body 2 to be opened and closed, and the tub (4) a rack (8) on which the dishes to be installed and placed therein are placed, and a spray arm (20) rotatably installed on the lower side of the rack (8) to inject washing water through the spray hole (20a). ), A sump (not shown) installed under the tub 4 to collect the washing water, and a washing pump (not shown) installed inside the sump to pump and supply the washing water toward the injection arm 20. It comprises a heater assembly (not shown) for heating the wash water inside the sump.

The door 6 is provided with a blower assembly 7 which blows the humid air therein to the outside when the dishes are dried, and a detergent injection device 10 for storing detergent to be put into the dishes.

Referring to FIG. 2, the detergent dosing device 10 includes a detergent inlet 11 for accommodating a detergent in a powder state for dishwashing, and a detergent in a liquid state (hereinafter referred to as “rinse”) that is added during a rinsing stroke. ) Is roughly divided into a rinse input 12 which is accommodated.

The detergent input unit 11 inputs a detergent used to wash the dishes, and the rinsing input unit 12 improves the drying efficiency of the dishes and injects the rinse to shine the dishes in a rinsing stroke.

When the user injects the rinse input unit 12 into the rinse input unit 12 and adjusts the amount of one dose, the rinse input unit 12 is stored therein while the inlet 13 of the rinse input unit 12 is opened during the rinsing stroke. Rinsing is done.

At this time, the rinse is introduced in a manner that simply flows out while the inlet 13 is opened, mixed with the sprayed washing water is collected to the bottom sump (not shown). Then, the sump (not shown) is sent to the injection arm 20 by a washing pump (not shown) and is sprayed on the tableware.

However, the rinsing device of the conventional dishwasher has the following problems.

Since the rinse of the rinse accommodating part 12 is mixed with the washing water and sprayed onto the tableware through the spray arm 20, the rinse is completely washed out in the washing water and takes a long time until the washing is mixed with the washing water. In addition, since the rinse is diluted and sprayed with water, the amount of the rinse consumed in the dilution process and the process of collecting water to the sump, there is a problem that the amount of the rinse is used as a whole.

In addition, there is a problem that the rinse that flows out of the inlet 23 of the rinse injection unit 12 is not washed by the washing water sprayed from the injection arm 20.

The present invention is to solve the above problems, an object of the present invention is to provide a dishwasher that can increase the effect of the rinse by spraying the rinse directly to the tableware, and also reduce the amount of the rinse.

In order to achieve the above object, the present invention, the rinse container for receiving / storing the rinse; An injection nozzle in which the rinse stored in the rinse barrel is injected into the tub; A plunger inserted into the rinse barrel to pressurize the rinse with the injection nozzle; It is connected to the plunger, and provides a detergent dispensing apparatus of the dishwasher comprising a drive unit: for driving the force to enter and exit the plunger inside the rinse barrel.

The drive unit may include a motor, a cam shaft for transmitting power to rotate the cam as the motor operates, and a cam shaft for pressing the plunger by receiving power of the motor.

Alternatively, the driving unit may be a solenoid that pressurizes the plunger as power is applied.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

The same components as in the prior art are given the same names and the same reference numerals for convenience of description, and detailed description thereof will be omitted.

Referring to Figures 3 and 4, the dishwasher according to an embodiment of the present invention will be described.

As shown in FIG. 3, the detergent dosing device 100 according to the present invention includes a detergent dosing unit 110 for accommodating / injecting a powdered detergent used for washing and a rinse of a liquid state used for rinsing. It is roughly divided into the rinse input unit 120 to receive / input.

The detergent input part 110 forms a front surface of the detergent receiving part 112 and a detergent receiving part 112 therein, and the detergent receiving part 112 opens and closes the detergent receiving part 112 when the detergent is introduced. The door 111 is made.

In addition, the rinse input portion 120 forms a front surface of the rinse accommodation portion 122 and the rinse accommodation portion 122 storing the rinse therein, and a cover in which a spray nozzle 123 through which the rinse is sprayed is formed ( 121).

As shown in FIG. 4, the rinse input unit 120 is inserted into the rinse barrel 130 in which the rinse is accommodated, and the rinse barrel 130 is inserted into and out of the rinse barrel 130. It is configured to include a plunger (131) and possibly a drive unit 140 for applying a force to the plunger (131).

A portion of the plunger 131 is installed to be exposed to the outside of the rinse barrel 130, and the driving unit 140 is installed in contact with the exposed portion.

The driving unit 140 preferably uses a cam driving device that transmits a force so that the plunger 131 makes a linear movement while the cam 141 rotates. Referring to the configuration, the driving unit 140 contacts the plunger 131. The cam 141 rotates as the motor (not shown) operates and the cam shaft 142 transfers power of the motor (not shown) to the cam 141.

On the other hand, the dishwasher is provided with a control unit including a microcomputer (not shown) for controlling the operation of the dishwasher of the dishwasher, the drive unit 140 is controlled through the microcomputer.

Therefore, when power is applied to a motor (not shown), as the cam shaft 142 and the cam 141 are driven, the cam 141 rotates and periodically presses the plunger 131 to rinse the cylinder 130. ) Insert it inside.

In addition, as the plunger 131 is pressurized, while the internal volume of the rinse barrel 130 decreases, the pressure therein increases and the rinse is injected.

At this time, the plunger 131 is inserted into the rinse barrel 130 at a high speed in a short time and acts at a high pressure, so that the particles of the rinse sprayed from the injection nozzle 123 become fine.

In addition, a spring 132 that elastically supports the plunger 131 is pressurized to be returned to its original position after the rinse is injected, and the rinsing cylinder 130 is compressed.

On the other hand, since the detergent dosing device 100 is installed inside the door 6 of the dishwasher (see FIG. 1), the detergent dosing device 100 and the rinsing dosing unit 120 is limited in the thickness, so The rinse barrel 130 and the plunger 131 in the rinse input portion 120 may be installed in parallel with the cover 121.

That is, as shown in Figure 4, the plunger 131 is preferably installed to reciprocate in the vertical direction.

When the plunger 131 is installed in parallel with the cover 121 as described above, the volume of the rinse barrel 130 can be formed relatively thin while the volume of the rinse barrel 130 is relatively large.

Therefore, looking at the operation of the detergent dispenser of the dishwasher according to the present invention.

First, when the user injects the rinse into the rinse barrel 130, closes the door 6, and operates the dishwasher, a series of washing strokes are performed in sequence.

Then, when the rinse is to be put in the washing stroke, the power is applied to the drive unit 140, the cam 141 is rotated, the plunger 131 is rotated in the direction in which the radius of the cam 141 is increased Pressurized.

In addition, as the plunger 131 is inserted into the rinse barrel 130, the rinse inside the rinse barrel 130 is compressed and injected into the tub 4 from the injection nozzle 123.

After the spraying of the rinse, the cam 141 is rotated in a direction of decreasing radius, the plunger 131 is released from the pressure applied by the cam 141 and the force of the spring 123 is applied to the place Will return.

Referring to Figure 5, when describing the detergent dispenser of the dishwasher according to a second embodiment of the present invention.

The basic configuration of the second embodiment is the same as that of the first embodiment described above.

However, in this embodiment, unlike the first embodiment described above, the driving unit 240 for pressing the plunger 231 is characterized in that the solenoid.

The solenoid 240 is connected to a microcomputer (not shown) of the control unit for controlling the dishwasher, and when power is applied to the solenoid 240, the plunger 231 is rapidly inserted into the rinse barrel 230. The rinse inside is compressed.

When the power supply of the solenoid 240 is released, the plunger 231 returns to its original position by the force of the spring 232 provided in the rinse barrel 230.

Meanwhile, in the second embodiment, the plunger 231 is installed to reciprocate in a direction perpendicular to the cover 121, but similarly to the first embodiment described above, the plunger 231 is installed to reciprocate in parallel with the cover 121. It can be easily understood.

On the other hand, as in the embodiment of the present invention, when using a method of spraying the rinse in the injection nozzle, the particles of the sprayed rinse is fine, it is uniformly spread quickly inside the tub and dishes.

In addition, since the injection of the rinse is controlled through the microcomputer of the controller, it is easy to adjust the single injection amount of the rinse, and it is also possible to control the rinse by dividing the rinse into several circuits.

On the other hand, since the detergent injection device of the dishwasher according to the present invention sprays the rinse directly to the dishes stored in the rack, it will be possible to install the detergent injection device in each position corresponding to the upper and lower racks.

However, when the rinse is sprayed, the particles are finely dispersed uniformly at high speed in the tub and the tableware, so that the rinse can be uniformly sprayed even if only one predetermined place is provided.

The present invention is not limited to the above-described embodiments, and as can be seen in the appended claims, modifications can be made by those skilled in the art to which the invention pertains, and such modifications are within the scope of the present invention.

When explaining the effect of the detergent dispenser of the dishwasher according to the present invention described above are as follows.

First, since the rinse is directly sprayed on the tableware, there is an advantage that the effect of the rinse rinse effectively.

Second, since the rinse is not diluted with the washing water and does not need to be re-injected, it is possible to prevent the rinse from being wasted during the dilution with the washing water, thereby reducing the amount of rinse.

Third, since the one-time input of the rinse is controlled relatively accurately, by preventing the excessive / under-use of the rinse, it is possible to prevent the waste of the rinse, there is an advantage that the rinse rinsing efficiency is increased.
