[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to an ice maker that automatically supplies water to an ice tray, separates ice from the ice tray, and stores ice, and supplies water to an empty ice tray for each ice maker. And a water supply device for automatic ice making.

[0002]

2. Description of the Related Art In general, as shown in FIG. 3, a water supply tank b for storing water and a purification filter c can be attached, and a certain amount of water in the water supply tank b can be quantified. And the quantitative cup d
A water supply pump e adapted to supply the determined amount of water to an ice tray (not shown), and an apparatus base material f to which a fixed amount cup d is detachable. There is known an automatic ice making water supply device a adapted to supply water to a dish.

[0003] Conventionally, this automatic ice making water supply device a
Since the purifying function of the purifying filter c deteriorates due to long-term use or the like, the purifying filter c is detached from the measuring cup d, and the purifying filter c is washed or replaced with a new one.

[0004]

However, in the case where the replacement filter c has been mounted in an incomplete state slightly floating from the fixed quantity cup d, the replacement filter c has to be removed from the water supply tank b. The outflowing water is supplied to the ice tray without passing through the purification filter c. As a result, inconvenience such as formation of ice by water that is not deodorized occurs.

The present invention has been made in view of the above circumstances, and is intended for an automatic ice making device capable of preventing a purification filter from being in an incompletely mounted state and always supplying purified water to an ice tray. It is intended to provide a water supply device.

[0006]

According to the present invention, there is provided an automatic ice making water supply apparatus for solving the above-mentioned problems, wherein a water supply tank for storing water, a purification filter can be attached, and a water supply tank is provided. Quantitative cup that was able to quantify a certain amount of water inside, and water quantified in this quantitative cup,
Automatic water supply for ice making provided with a water supply pump adapted to supply to an ice tray, and a device base having a fixed quantity cup detachable, and adapted to supply water to the ice tray at each of a series of ice making steps. An apparatus, wherein a projection for positioning a purification filter at a predetermined mounting position is provided on an apparatus base in a state where a fixed amount cup is mounted on the apparatus base.

[0007]

According to the present invention, since the projection for positioning the purification filter at a predetermined mounting position is provided on the apparatus base in a state where the quantitative cup is mounted on the apparatus base, the purification attached to the quantitative cup is provided. Even if the filter is in an incomplete state, when the metering cup is mounted on the apparatus base material, it is positioned on the projection and the purification filter is mounted at a predetermined mounting position.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 schematically shows the entire configuration of an automatic ice making water supply device (hereinafter simply referred to as a water supply device) 1.

That is, the water supply apparatus 1 includes a water supply tank 2, a fixed quantity cup 4 to which a purification filter 3 can be attached, a water supply pump 5, and a device base 6 for attaching and detaching the fixed quantity cup 4. The device base 6 is provided with a protrusion 61 for positioning the purification filter 3 at a predetermined mounting position.

The water supply tank 2 is provided with a water receiving chamber 4 for the measuring cup 4.
A water outlet 21 having a valve 22 is provided at a water outlet 21 protruding from the bottom at one end side so as to be mounted on a water outlet receiver 44 of the metering cup 4. The valve 22 is opened in this mounted state. And
The cut-out portion 24 of the water outlet 23 is configured to set the upper limit water level of the water receiving chamber 41 and the fixed-quantity chamber 42 of the fixed-quantity cup 4 by being replaced with air.

The metering cup 4 includes a water receiving chamber 41 and a metering chamber 42.
It consists of In the water receiving chamber 41, an attachment portion 43 for attaching the purification filter 3 is formed.
Then, in a state where the purification filter 3 is attached to the attachment portion 43, the water in the water receiving chamber 41 passes through the purification filter 3, and then is supplied to the water supply control provided between the water receiving chamber 41 and the quantitative chamber 42. The amount is determined in the measuring chamber 42 through the small hole 40. The water supply control holes 40 are small, and the flow rate of water passing through the water supply control holes 40 is extremely small. Therefore, when the water in the fixed amount chamber 42 is drained at the time of water supply, the water flows out from the water receiving chamber 41 to the fixed amount chamber 42 through the small hole 40 for water supply control. Yes, the amount of water is practically negligible.

The water supply pump 5 sucks the water measured in the metering chamber 42 and supplies it to an ice tray (not shown) through a water supply pipe 51.

The apparatus base 6 fixes the water supply tank 2 and the water supply pump 5. The metering cup 4 is detachably attached to the device base 6.
That is, by attaching the fixed quantity cup 4 to the apparatus base material 6, the fixed quantity cup 4 is attached to a predetermined position with respect to the water supply tank 2, the water supply pump 5, and the like. Then, the mounting portion 43 of the fixed amount cup 4 is
The device base 6 located above the cleaning filter 3 is provided with a projection 61 for positioning an upper portion of the cleaning filter 3 at the mounting position. The shape and the like of the projection 61 are not particularly limited as long as it can position the upper portion at the mounting position of the purification filter 3.

According to the water supply apparatus 1, as shown in FIG. 2, the purifying filter 3 is not completely attached to the attaching portion 43 of the quantitative cup 4, and the quantitative cup 4 is attached to the apparatus base with the bottom floating. 6, the purifying filter 3 is pushed into the mounting portion 43 by the projection 61, so that after the quantitative cup 4 is mounted, as shown in FIG. State. For this reason, it is possible to prevent water from being supplied to the ice tray without passing through the purification filter 3, and it is possible to always make delicious ice.

[0016]

As described above, according to the present invention, even when the purifying filter attached to the measuring cup is in an incomplete state, the purifying filter can be set to a predetermined value by attaching the measuring cup to the apparatus base material. Can be supplied to the ice tray so that delicious ice can be produced.
