The present invention relates to an ice maker, and more particularly, to an ice maker that vibrates while the ice box (hereinafter referred to as an ice tray) swings up and down and drops / separates iced ice by centrifugal force.

An ice maker is a device that cools supplied ice-making water. Recently, an ice-making vibrating device has been proposed to prevent a phenomenon in which ice bubbles swell while freezing bubbles in ice-making water. .

That is, the ice maker disclosed in Korean Patent No. 10-0272894 includes an ice maker body 10, an ice making unit 20, an air bubble removing means 30, and an ice making completion detecting means 40.

The double bubble removing means 30 is to remove the bubbles in the ice-making water to prevent clouding from occurring during ice-making, the rocking plate 31 and the rocking plate 31 swinging up and down in the ice box 21 ) Is provided with a swinging motor 32 for swinging.

When the locking piece 33 installed on the swinging motor 32 lifts up the locking pin 34 of the swinging plate 31, the swinging plate 31 moves to lift and remove bubbles in the ice making water.

When the ice making water flows into the ice making box 31 through the ice making water supply pipe 14 and the cooling protrusions 24 are immersed in the ice making water, the cooling protrusions cooled below the freezing point by heat exchange of the refrigerant flowing through the evaporation pipe 23. Cooling water freezes around (24).

At this time, while the swinging motor 32 operates, the swinging plate 31 which is immersed in the ice making water swings up and down. As a result, the ice making water swings up and down, bubbles in the ice making water are removed, and transparent ice grows around the cooling projections 24.

There are some problems in swinging ice-making water in ice trays in such ice machines.

That is, the conventional ice maker vibrates to prevent 'cloudiness', the vibration plate vibrates up and down at the bottom side of the ice box to generate vibration at the bottom of the ice-making water, so the vibration efficiency applied to the ice-making water is low. As it is in contact with ice water, foreign substances inside the ice box are easily pinched by long-term use.To clean such substances, the relevant parts of the ice box must be completely and disassembled, and even in the release structure for removing ice, the outside of the ice box Although the ice making box has a rotational structure of only a predetermined angle, the rotational structure toward the outside is not only complicated, but also to clean the inside, there is a problem that all the rotational configurations must be disassembled.

The ice maker of the present invention according to the drawings is largely the upper frame 110, the lower frame 120, the ice tray 130, the lever lever 140, the first drive motor 142 and the rotating means 150 )

The upper frame 110 is connected to the refrigeration system on the bottom of the horizontal plate, the evaporator tube 111 and the water pipe 113 formed with the cooling projection 112 is installed.

Above the upper frame 110, the auxiliary frame 114 is secured by the support bar 116 while being wound on the coil spring 115 to absorb a predetermined vibration, and the auxiliary frame 114 is formed on the auxiliary frame 114. The two drive motor 152 is mounted.

The lower frame 120 is positioned below the upper frame 110 to form a predetermined ice loading space, and forms ice outlets 121 and drain holes 123 at predetermined positions on the sidewalls thereof, and separate ice is loaded. In addition, the porous plate 122 is installed to drain the water to the bottom.

The ice tray 130 forms a predetermined depth so that the cooling protrusions 112 of the upper frame 110 are immersed in the supply water, and the swing shaft 132 is vertically / connected to the center thereof.

The ice tray 130 is a dish-shaped cylindrical cylinder of the upper opening that forms a shallow and wide accommodating space so that ice of a predetermined size is accommodated.

The swing shaft 132 has a lower end penetrating / disengaging as a nut 134 at a bottom or an upper surface through the center of the ice making plate 130, and is easily separated / assembled from the ice making plate 130.

In particular, an upper end of the swing shaft 132 forms a vertical groove 132 a inwardly, and a lower end of the drive shaft 152 a of the second driving motor 152 is inserted into and coupled to the vertical groove 132 a. 152b), the swing shaft 132 has an insertion interval capable of repeating / rising to a predetermined height, and the swing shaft 132 is also rotated when the driving shaft 152a of the second driving motor 152 is rotated. The vertical groove 132a and the protrusion 152b are coupled.

The lever lever 140 has one end connected to the swing shaft 132 in the form of a fork, and the other end is connected to the cam 144 about an axis point (not shown).

The cam 144 is connected to the eccentric shaft and the first drive motor 142, and can be sequentially controlled as a predetermined control signal.

Rotating means 150 is a second drive motor 152 mounted on the upper end of the swing shaft 132, and rotates the ice tray 130.

Therefore, the ice tray 130 is rotated to empty the ice tray 130 filled with ice formed on the cooling protrusion 112, and the ice drops on the porous plate 122 of the lower frame 120.

4A and 4B are sectional views of the ice maker of the present invention.

It describes the vibration action for removing bubbles during the ice making of the present invention ice maker according to the drawings.

That is, a predetermined amount of water is filled through the water pipe 113 so that the cooling protrusions 112 of the upper frame 110 are immersed in the supply water of the ice making plate 130 having a shallow and wide receiving space.

When the cooling protrusion 112 is immersed in the water filled to a predetermined height to an appropriate depth, the refrigeration system starts and the first driving motor 142 is driven to rock the ice tray 130.

Ice is grown by the evaporation of the cooling projection 112 which is simultaneously started with the shaking of the ice making plate 130. As a result of the fluctuation of the effective ice tray, the ice of the crystal corner 112 is grown with clear crystal ice, which is prevented from clouding.

Oscillation of the ice tray 130 causes the first driving motor 142 to be driven to rotate the eccentric cam 144 connected on the same axis so as to tilt both ends of the lever lever 140 in contact with each other in opposite directions. Accordingly, the swing shaft 132 moves the ice tray 130 up and down.

Then, the upper and lower repetitive fluctuations of the ice making plate 130 stops at the same time as the driving of the first driving motor 142 stops at the moment when ice growth of the cooling protrusion 112 ends and ice ice is detected by a predetermined sensing means. The second driving motor 152 is directly driven to drop the ice ice in the ice tray.

Since the oscillation shaft 132 connected to the driving shaft 152a is rotated by the driving of the second driving motor 152, the ice making plate 130 fixed to the lower end thereof rotates horizontally.

The oscillation shaft 132 forms a large diameter hole having a vertical groove 132a formed inside the upper end thereof, and a lower end of the driving shaft 152a of the second driving motor 152 is coupled to the vertical groove 132a. The protrusion 152b is formed on the outer circumferential surface having a diameter of a small diameter so as to be a predetermined depth, and when the swing shaft 132 repeats / rises, it is possible to repeatedly swing up and down by this depth. After stopping, it has a pipe connection structure that is not a problem in rotating the swing shaft 132 engaged with the drive shaft 152a.

Unlike the first driving motor 142, the second driving motor 152 is rotated at a high speed, so that the ice placed therein is separated from the outside due to the centrifugal force of the ice making plate. do.

The separated ice is dropped and loaded into the ice loading space of the lower frame 120.

The loaded ice is withdrawn through the outlet 121, and the remaining moisture generated at the same time as the ice is also discharged through the drain 123 from the bottom through the porous plate 122.

When the ice making process of the first cycle is completed, the second driving motor 152 is stopped and water is supplied again, and the refrigerating cycle is resumed. The first driving motor 142 is also driven again, thereby making it clear without clouding. You get ice.

Since the overall control of the first and second driving motors 142 and 152, the ice making state detecting means, and the water level detecting means is controlled by using a known switching circuit and a program, a detailed description thereof is omitted.

As described above, the present invention improves the problems of the conventional ice maker, and not the oscillating device in the ice tray, but repeatedly swings the ice tray itself up and down. It has the effect of preventing the water contact between the ice making water and the vibration means by improving the non-hygienicity generated by the immersed structure, and in particular, the rocking structure is simple and controllable by allowing the ice making plate containing the ice making water to swing up and down. It will provide an ice maker easier.

The present invention provides a new ice drop structure in which the ice contained by rotating itself is separated / dropped by centrifugal force, rather than the structure of tilting the ice making plate at a predetermined angle and reverting it as in the related art.

The present invention provides a new swinging method for rocking the ice box itself outside the ice maker, but by implementing a vibration generating device together with an ice making box rotating device for dropping ice, the ice making machine having a simple structure that reduces the installation space of the rotating device and the vibration generating device. There is also the effect of providing.

 The present invention has an effect that is easy to disassemble for cleaning the ice trays by separating / combining the ice trays with the plate and the swing shaft filled with ice trays.
