Description

Ice purifier and ice generating device {WATER PURIFIER HAVING ICE-MAKER AND ICE MAKING DEVICE}

The present invention relates to an ice purifier and an ice generating device, and in more detail, ice is excessively grown, so that water for ice generation and a storage unit storing ice generated therefrom are deicing at a deicing location where ice is discharged. It relates to an ice purifier and an ice generating device that can be prepared in case of not being able to return to the position.

Water purifiers on the market in recent years are generally capable of providing ice to users. In order to provide ice as described above, the ice purifier must have an ice making means capable of making ice therein. In addition to this, the ice purifier must have an ice storage for temporarily storing ice made by the ice making means therein. That is, recently marketed ice water purifiers have a structure in which ice is made by an ice making means and then stored in an ice storage, and when a user requests ice, ice in the ice storage is provided to the user.

Here, the ice making means may include a tray for storing water, and a finger immersed in water of the tray to cool the water in the tray. However, when the ice is too large, the ice may not be deiced even by a deicing operation that separates the ice from the ice making means. In this case, the ice can hold the tray and fingers together, making it difficult for the tray to operate smoothly. In addition, even if the tray is forcibly operated by the driving force of the motor, it may be difficult for the tray to return to its original position due to ice remaining in the fingers or the like. In this case, since it is difficult to normally supply purified water to the inclined tray due to ice, it is difficult for the next ice making operation to occur smoothly.

Therefore, the present invention was conceived to solve the above problems, and the object of the present invention is that the ice is excessively grown, and the water for ice generation and the storage unit for storing ice generated therefrom are at a de-icing location where ice is discharged. It is to provide an ice purifier and an ice generating device in case it is not possible to return to the ice making position where ice making occurs.

An ice water purifier according to an aspect of the present invention comprises: a filter unit for generating purified water by purifying raw water; A storage unit receiving and storing purified water for ice generation from the filter unit; A cooling unit for generating ice by cooling the purified water in the storage unit; A flow path part provided adjacent to the cooling part; And a control unit for controlling the ice generated by the cooling unit to be de-icing, wherein the storage unit is supplied with the purified water, and the first location where the ice is generated and the stored material inside are discharged to the outside. Is rotated between the second position, and the control unit returns to the first position from the second position after the ice is generated and the storage unit is rotated from the first position to the second position. If not determined, a first control is performed to remove ice suspended from the cooling unit, and the first control may include a control to allow purified water generated by the filter unit to flow along the flow path.

In addition, an ice generating apparatus according to an aspect of the present invention includes an ice generating apparatus for generating ice by cooling water, comprising: a storage unit receiving and storing water for generating the ice; A cooling unit for generating the ice by cooling the water in the storage unit; A flow path part provided adjacent to the cooling part; And a control unit for controlling the ice generated by the cooling unit to be deiced, wherein the storage unit is supplied with the water and the first location where the ice is generated and the stored material inside are discharged to the outside. Is rotated between the second position, and the control unit returns to the first position from the second position after the ice is generated and the storage unit is rotated from the first position to the second position. If it is not determined to be, a first control for removing ice from the cooling unit is performed, and the first control may include a control for allowing the water to flow along the flow path.

In the ice purifier and ice generating device according to the present invention, due to excessive growth of ice, the water for ice generation and the storage unit for storing ice generated therefrom do not return to the ice making position in which ice is being discharged from the ice-removing position. If it is not possible, there is an effect of performing an additional operation for de-icing so that de-icing and de-icing occur smoothly.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the present invention is not limited or limited by the following examples.

[Example 1]

1 is a conceptual diagram conceptually showing an ice purifier according to a first embodiment of the present invention. As shown in FIG. 1, the ice purifier according to the first embodiment of the present invention basically includes a filter unit 110, a storage unit 120, a cooling unit 130, and a control unit (not shown).

Basic configuration

First, a look at the filter unit 110. The filter unit 110 generates purified water by purifying the raw water after receiving raw water from the outside. The filter unit 110 may include several filters. For example, the filter unit 110 may include a sun carbon filter, a membrane filter, and a thick carbon filter. In addition, the filter unit 110 may include an electric deionization type filter. Representatively, the electrodeionization method includes EDI (Electro Deionization), CEDI (Continuous Electro Deionization), and CDI (Capacitive Deionization) methods.

Next, look at the storage unit 120. The storage unit 120 stores purified water supplied from the filter unit 110. The storage unit 120 may receive purified water directly or indirectly from the filter unit 110. For example, the storage unit 120 may receive purified water directly from the filter unit 110 as shown in FIG. 1, or may receive purified water from a tank storing purified water generated by the filter unit 110. have. In addition, the storage unit 120 may store purified water supplied from the auxiliary tank unit 150 to be described later (refer to the arrow indicated by the dotted line in FIG. 1 ). The purified water in the storage unit 120 is cooled by a cooling unit 130 to be described later to become ice. The storage unit 120 will be described in detail below with reference to FIG. 2. FIG. 2 is a perspective view illustrating a storage unit of the ice purifier of FIG. 1.

The storage unit 120 may include the tray 121 shown in FIG. 2. The tray 121 stores purified water therein. In this embodiment, the tray 121 may have a discharge port 122 for discharging purified water from the inside to the outside. The outlet 122 may be formed to be spaced apart from the inner bottom of the tray 121 by a predetermined height upward. Here, when purified water is discharged from the discharge port 122, it can be seen that purified water is stored in the tray 121 as high as the height of the discharge port 122. The ice water purifier according to the present embodiment may confirm the quantitative storage of purified water through this. That is, the ice purifier according to the present embodiment may supply purified water to the tray 121 until purified water is discharged from the outlet 122 for quantitative supply.

Next, look at the cooling unit 130. The cooling unit 130 cools purified water in the storage unit 120 to generate ice. The cooling unit 130 will be described in more detail with reference to FIGS. 3 to 5. 3 is a sectional view showing a simple storage unit and a cooling unit of the ice purifier of Fig. 1, Fig. 4 is a perspective view showing the cooling unit of the ice purifier of Fig. 1 from above, and Fig. 5 is a view of the ice purifier of Fig. 1 It is a perspective view showing the cooling part as viewed from below.

The cooling unit 130 may include a finger 131 that is immersed in the purified water of the tray 121 to cool the purified water of the tray 121. The fingers 131 cool the purified water in the tray 121 through a refrigerant. That is, when the refrigerant in the finger 131 is evaporated, purified water in the tray 121 may be cooled by this. With such cooling, ice is generated inside the tray 121 and can be suspended from the fingers 131 (see FIG. 3 ). In addition, the cooling unit 130 may further include a base 132 to guide the refrigerant to the fingers 131. The base 132 is connected to the finger 131 from the upper side of the finger 131 to guide the refrigerant to the finger 131. The refrigerant repeatedly undergoes compression, condensation, expansion and evaporation, providing the cooling heat required for ice formation. The provision of cold heat by a refrigerant is a very obvious technique to a person skilled in the art.

Next, the operation of the tray 121 will be described with reference to FIG. 6. Ice generated by the cooling unit 130 is supplied to an ice storage unit 140 to be described later. For this supply, the tray 121 rotates between a first position (A, storage position) and a second position (B, discharge position). (To implement such rotation, a synchronous motor may be further provided.) More specifically, the first position A is a position where purified water is supplied to the tray 121 and ice is generated. The second position is a position in which the storage material (ice and residual water) of the tray 121 is discharged to the outside of the tray 121. When the tray 121 is rotated from the first position to the second position, the storage of the tray 121 may be discharged to the outside. In this case, in order to supply the storage of the tray 121 to the ice storage 140, the storage 120 may further include a guide 123 for guiding the storage to the ice storage 140 (FIG. 2 , 3, 6).

However, when the cold water generation unit 160 to be described later is located above the cold water storage unit 170 to be described later, the cold water is dropped from the cold water generation unit 160 as it is. Can be supplied with. That is, purified water may be supplied to the cold water storage unit 170 after flowing along the flow path 200 (see FIG. 4 ), which will be described later, and then dropping as it is. However, when the tray 121 is located under the cold water generating unit 160, it is difficult to supply cold water to the cold water storage unit 170. Accordingly, when the cold water is discharged from the cold water generating unit 160, the tray 121 is preferably rotated to the third position (C). Alternatively, it may be considered to extend the end of the flow path part 200 to the outside of the tray 121 to be described later.

Next, look at the control unit. The control unit performs control for removing ice generated by the cooling unit. In order to describe the control by the controller, a process of generating ice by the ice purifier according to the present embodiment will be described in sequence with reference to FIG. 1.

Control by the control unit

First, raw water is supplied to the filter unit 110. The raw water is purified by the filter unit 110 to become purified water. Purified water is supplied to and stored in the tray 121 (storage unit). At this time, the tray 121 is located in the first position. When a predetermined amount of purified water is supplied to the tray 121, the fingers 131 of the cooling unit 130 cool the purified water of the tray 121 while being immersed in the purified water of the tray 121. As a result of this, the purified water in the tray 121 is cooled to become ice and hangs on the fingers 131 (see FIG. 3). In order to supply such ice to the ice storage unit 140 to be described later, it is necessary to remove ice. That is, it is necessary to separate the ice from the fingers 131 before rotating the tray 121 to the second position.

To this end, the ice purifier according to the present embodiment may further include a heating unit (not shown) that applies heat to ice. The heating unit may separate the ice from the fingers 131 by melting the ice by applying heat to the ice. The heating unit may use a high-temperature gas or heater to heat the ice. Alternatively, the heating unit may use water having a temperature higher than 0 °C. For example, the heating unit may utilize purified water generated by the filter unit 110 or hot water generated by the hot water generation unit 180 to be described later for ice removal.

In addition, the heating unit may directly or indirectly apply heat to the ice. For example, if the heating unit is installed adjacent to the ice, the heating unit can directly apply heat to the ice. Alternatively, the heating unit may be installed adjacent to the base 132 of the cooling unit 130. In this case, the heat of the heating unit is transferred from the base 132 to the fingers 131 and from the fingers 131 to ice to melt the ice suspended from the fingers 131. Alternatively, ice may be melted and de-iced without a heating unit. For example, when a predetermined time elapses after the operation of the cooling unit 130 is stopped, the ice will naturally melt and de-icing. When ice is removed by the above ice removal operations, the tray 121 rotates from the first position to the second position as shown in FIG. 6. With this rotation, ice and residual water in the tray 121 are supplied to the ice storage unit 140.

However, when ice is generated too large, for example, when ice is additionally generated around ice that has not been removed in the previous ice removal operation, or when ice sticks to each other in adjacent fingers 131 and is generated together The ice may not be de-iced on the back even by the above-described de-icing operations. In this case, it may be difficult for the tray 121 to rotate to the second position because ice holds the tray 121 and the fingers 131 together. In addition, even if the tray 121 is forcibly rotated by the driving force of the motor, it may be difficult for the tray 121 to completely return to the first position due to ice remaining on the fingers 131. In this case, since it is difficult to normally supply purified water to the inclined tray 121 due to ice, it is difficult for the next ice making operation to occur smoothly.

In order to solve the above problem, the control unit indicates that the tray 121 has returned from the second position to the first position after the ice is generated and the tray 121 (storage unit) is rotated from the first position to the second position. If not determined, a first control is performed to remove ice from the finger 131 (cooling unit). This will be described in detail below.

In this embodiment, the control unit very simply recognizes the problem that ice is not de-icing. That is, in this embodiment, after the ice is generated and the tray 121 is rotated from the first position to the second position, if it is not determined that the tray 121 has returned from the second position to the first position, It is recognized that the above problem has occurred. More specifically, after the ice is generated and the tray 121 rotates from the first position to the second position, if the tray 121 is not detected in the first position for a predetermined time, the above problem is recognized as occurring. do.

It is not easy to directly detect ice formation or de-icing. Accordingly, the passage of time can be utilized as an alternative to direct sensing. For example, when a predetermined time elapses from the time when the compressor (not shown) starts to operate for the operation of the cooling unit 130, it is determined that ice has been generated. It can be determined that this is de-icing.

That is, after supplying a fixed amount of purified water to the tray 121 in the first position, the cooling unit 130 is operated, and when a predetermined time elapses after the cooling unit 130 is operated, the heating unit is operated by determining that ice has been generated. When a predetermined time elapses after the operation of the heating unit, it is determined that the ice has been removed, and the tray 121 is rotated to the second position, and when a predetermined time elapses after the rotation of the tray 121, the tray 121 is restarted to the first position. Control to return to the position can be made.

In this embodiment, the control unit may also use time as described above to recognize a problem that ice has not been removed. For example, after ice is generated and the tray 121 rotates from the first position to the second position, the above problem is recognized if the tray 121 is not detected in the first position for a predetermined time. can do. At this time, the predetermined time may be set in various ways. For example, the predetermined time may be set as a time normally taken from the time when the tray 121 starts rotating at the second position until it reaches the first position.

The ice purifier according to the present embodiment may further include a sensor unit (not shown) that detects whether the tray 121 is located in the first position. For example, the sensor unit may be a micro switch installed at the first position. When the tray 121 completely arrives at the first position and presses the switch of the micro switch, the control unit may determine that the tray 121 is located at the first position. In addition, when the micro switch is additionally installed in the second position, the timing at which the tray 121 starts to rotate in the second position may also be detected.

As a result, if the switch in the first position is not pressed for a predetermined time (for example, 50 seconds) from the time when the tray 121 is separated from the switch in the second position, the control unit may determine that a problem of non-release ice has occurred. .

If the control unit determines that the above problem has occurred, it performs the first control. Here, the first control is a control for removing ice suspended from the fingers 131 (cooling unit). More specifically, in this embodiment, the first control is a control for operating the above-described heating unit. To this end, the ice purifier according to the present embodiment includes the above-described heating unit. That is, the control unit may separate the ice from the finger 131 by melting the ice suspended on the finger 131 by operating the heating unit for a predetermined time. Then, when the tray 121 returns to the first position, the next ice making operation may be performed.

On the other hand, the control unit may further control the tray 121 to move to the second position before performing the first control. The tray 121 may continue to receive driving force from the motor until it reaches the target point. However, in this case, when a non-icing problem occurs, an excessive force may be applied to the motor due to continuous operation of the motor. In addition, it is not desirable to perform the next ice making operation while the ice de-icing is stored in the tray 121 in consideration of the problem of excessive ice generation. Accordingly, before performing the first control, it is preferable that the control unit further perform control to cause the tray 121 to move to the second position.

In addition, it is preferable that the control unit performs the first control again if it is not determined that the tray 121 has returned to the first position from the second position even after performing the first control. For example, the control unit performs control to return the tray 121 to the first position, but if the tray 121 is not detected in the first position, the control moves the tray 121 to the second position and operates the heating unit. After this control, the control of returning the tray 121 to the first position is performed again, but if the tray 121 is still not detected in the first position, the tray 121 is moved back to the second position. And the control to operate the heating unit can be performed again. The above control may be repeated multiple times.

However, if it is not determined that the tray 121 has returned to the first position from the second position even after performing the first control a plurality of times as described above, it is preferable that the control unit further perform control to generate a fault signal. For example, the control unit may perform control such that a warning sound is generated or a warning lamp is turned on. This is to induce direct processing by users or administrators.

The control by the control unit described so far can be applied to an ice generating apparatus other than an ice purifier. For example, it may be applied to an ice generating device that generates ice in a refrigerator and supplies it to a user.

Additional configuration

The ice water purifier according to the present embodiment, as shown in FIG. 1, is an ice storage unit 140, an auxiliary tank unit 150, a cold water generation unit 160, a cold water storage unit 170, a hot water generation unit 180, and The flow path part 200 may be further included.

First, look at the ice storage unit 140. The ice storage unit 140 receives and stores ice generated in the storage unit 120 by the cooling unit 130. The ice storage unit 140 includes an ice transfer unit 191 to provide ice to a user. The ice transfer part 191 has a screw shape as shown in FIG. 1. Accordingly, the ice storage unit 140 may provide ice to a user by transferring ice to the discharge door 193 according to the rotation of the ice transfer unit 191 by the motor 192.

Next, look at the auxiliary tank unit 150. The auxiliary tank unit 150 collects and discharges purified water from the ice storage unit 140. The ice storage unit 140 is supplied with ice from the storage unit 120 as well as residual water (although purified water). In addition, purified water due to sea ice is present in the ice storage unit 140. The purified water of the ice storage unit 140 is collected in the auxiliary tank unit 150 and discharged to the outside. Alternatively, purified water from the ice storage unit 140 may be collected in the auxiliary tank unit 150 and then recovered to the storage unit 120 (refer to the arrow indicated by the dotted line in FIG. 1 ). When collected in this way, waste of purified water can be reduced. For reference, the auxiliary tank unit 150 may be integrally formed with the ice storage unit 140 or may be formed separately. In addition, purified water discharged from the discharge port 122 may also be collected in the auxiliary tank unit 150 and then discharged to the outside. Accordingly, the purified water discharged from the outlet 122 may be sensed by using the low water level sensor provided in the auxiliary tank unit 150 as it is.

Next, the cold water generation unit 160 will be described. The cold water generation unit 160 receives purified water generated by the filter unit 110 and then cools it to generate cold water. In this embodiment, the cold water generation unit 160 may cool purified water through the cooling unit 130. To this end, the cold water generation unit 160 may flow purified water along the flow path 200 provided adjacent to the cooling unit 130 (refer to the arrow in FIG. 4 ).

The cooling unit 130 goes down to a very low temperature to generate ice. Accordingly, when purified water flows along the flow path part 200 adjacent to the cooling part 130, it may be cooled by heat exchange. In this case, since there is no need to separately prepare a configuration for generating cold water, the ice purifier can be made very compact. As described above, in this embodiment, the flow path part 200 serves as the cold water generation part 160 when generating cold water. The cooling unit 130 may operate a compressor to operate a refrigerant not only when ice is generated but also when cold water is generated.

In this embodiment, the flow path part 200 may be provided between the U-shaped base 132 as shown in FIGS. 4 and 5 and formed along the length direction of the base 132. In this case, since the purified water flows along the flow path part 200 and receives cold heat from the fingers 131 and the base 132 on both sides, it is advantageous for cooling the purified water. The flow path part 200 is preferably inclined from one side to the other for natural flow of purified water.

Next, a look at the cold water storage unit 170. The cold water storage unit 170 receives and stores cold water from the cold water generation unit 160 (in this embodiment, the flow path unit). The cold water storage unit 170 stores cold water to be distinguished from the ice storage unit 140 as illustrated in FIG. 1. That is, ice (including residual water) generated by the cooling unit 130 is supplied to the ice storage unit 140, and the cold water generated by the cold water generation unit 160 is supplied to the cold water storage unit 170. The cold water of the cold water storage unit 170 may be supplied back to the cold water generation unit 160 to be cooled. Through this, the cold water in the cold water storage unit 170 can be maintained at a substantially constant temperature.

Next, the hot water generating unit 180 will be described. The hot water generation unit 180 receives purified water from the filter unit 110 and then heats it to generate hot water. The hot water generation unit 180 may include an instantaneous hot water module that instantaneously heats purified water supplied from the filter unit 110. Instantaneous hot water module is suitable for direct water purifier. That is, the instantaneous hot water module may receive purified water from the filter unit 110 whenever necessary and then heat it for a short time to generate hot water. Accordingly, when the instantaneous hot water module is provided, a hot water storage unit for storing hot water is unnecessary. For reference, purified water from the filter unit 110 may be selectively supplied to the storage unit 120, the cold water generation unit 160, and the hot water generation unit 180. To this end, a four-way valve may be provided in the conduit, or a valve may be separately provided for each conduit.

[Example 2]

The ice purifier according to Embodiment 2 of the present invention basically has the configuration of the ice purifier according to Embodiment 1 described above. However, the ice purifier according to the present exemplary embodiment differs from the ice purifier according to the first exemplary embodiment in control by the controller. Therefore, it will be described below mainly.

In this embodiment, after ice is generated and the tray 121 is rotated from the first position to the second position, if it is not determined that the tray 121 has returned from the second position to the first position, the finger ( 131 (cooling unit) as a first control to remove ice from the ice suspended from the filter unit 110, and control to allow purified water generated by the filter unit 110 to flow along the flow path unit 200 described above. Raw water usually has a temperature higher than 0 °C. Therefore, when purified water obtained by purifying raw water flows along the flow path part 200, ice suspended from the fingers 131 may be melted and deiced by heat transfer. In this case, purified water may be directly supplied from the filter unit 110 to the flow path 200, or may be supplied to the flow path 200 from a tank storing purified water.

In the present embodiment, the first control may be the same as the control for flowing purified water along the flow path 200 to generate cold water. However, when removing ice, the compressor of the cooling unit 130 needs to be stopped, and when cold water is generated, the compressor needs to be operated. In addition, in the present embodiment, the control unit may perform the control for operating the above-described heating unit in addition to the first control. For example, if it is not determined that the tray 121 has returned to the first position even after controlling the purified water to flow along the flow path 200, the control unit may additionally perform the control to operate the above-described heating unit. .

[Example 3]

The ice water purifier according to the third embodiment of the present invention basically has the configuration of the ice water purifier according to the first embodiment described above. However, the ice purifier according to the present embodiment differs from the ice purifier according to the above-described embodiments in control by the controller. Therefore, it will be described below mainly.

In this embodiment, after ice is generated and the tray 121 is rotated from the first position to the second position, if it is not determined that the tray 121 has returned from the second position to the first position, the finger ( 131 (cooling unit) as a first control to remove ice from the ice suspended from the cold water storage unit 170, and a control to allow the cold water stored in the cold water storage unit 170 to flow along the flow path unit 200 described above. The cold water generated by the cold water generating unit 160 and stored in the cold water storage unit 170 has a temperature higher than 0°C. Therefore, when cold water flows along the flow path part 200, ice suspended from the fingers 131 may be melted and de-iced by heat transfer.

When the cold water in the cold water storage unit 170 is at a certain temperature or higher, the control unit can perform control to circulate the cold water in the cold water storage unit 170 back to the cold water generation unit 160 (flow path) by a circulation pump (not shown). have. In this embodiment, the first control may be the same. However, when removing ice, the compressor of the cooling unit 130 needs to be stopped.

In this embodiment, the controller may perform the above-described controls for removing ice in addition to the first control. For example, the control unit performs control to return the tray 121 to the first position, but if the tray 121 is not detected in the first position for 50 seconds, the tray 121 is moved to the second position and the circulation pump Control is performed for 5 minutes, and after this control, the control of returning the tray 121 to the first position is performed again, but if the tray 121 is still not detected in the first position, the tray 121 is opened. The control is again moved to the second position and the circulation pump is operated for 10 minutes, and after this control, the control to return the tray 121 to the first position is again performed, but the tray 121 is still in the first position. If not detected, control can be taken to generate a fault signal.
