The present disclosure relates to a water purifier having an ice-making function, and more particularly, to a water purifier having an ice-making function that transfers refrigerant discharged from a discharge port of an ice-making evaporator to a cold water evaporator included in an ice storage tank under certain conditions and utilizes the refrigerant.

In general, water purifiers are those that cool or heat supplied water after purifying it and supply cold, purified or hot water to the user. They are divided into a storage type that is equipped with a water tank for storing cold, purified or hot water and stores purified water for a certain period of time and supplies it as needed, and an instantaneous type that has a storage capacity of 100 ml or less and is cooled/heated and supplied as soon as the water intake button is pressed.

Recently, water purifiers have been equipped with ice-making devices (or refrigeration systems) that can create ice, and are supplied as ice water purifiers, providing users with ice as well as cold and hot water.

Ice makers create ice by cooling water through a refrigeration system, and are supplied for home use, such as refrigerators or water purifiers, as well as for outdoor use, such as camping, and for commercial use, such as cafes or restaurants.

At this time, the refrigeration system included in the ice water purifier or ice maker circulates and compresses the refrigerant through a refrigerant circulation line consisting of a compressor, a condenser, an evaporator, and a capillary tube, and then causes the immersion tube of the evaporator to form ice on the ice tray.

However, conventional ice purifiers have a problem in that they cannot effectively utilize the energy remaining after ice is created.

The control module (110) executes a program stored in the memory (130) and controls the entire process of executing the water purifier control program. Each operation performed by the control module (110) will be examined in more detail later.

According to an exemplary embodiment, the control module (110) may include all kinds of devices capable of processing data. According to an exemplary embodiment, the control module (110) may be a hardware-embedded data processing device having a physically structured circuit to perform a function expressed by a code or command included in a program. As an example of a hardware-embedded data processing device, a processing device such as a microprocessor, a central processing unit (CPU), a processor core, a multiprocessor, an application-specific integrated circuit (ASIC), a field programmable gate array (FPGA), etc. may be included, but the technical idea of the present disclosure is not limited thereto.

According to an exemplary embodiment, the control module (110) may further include a valve module for effectively supplying refrigerant to a plurality of evaporators included in the water purifier (100) or selecting a path along which the refrigerant moves. The valve module may include a three-way valve, a four-way valve, or various types of valves.

A water purifier control program may be stored in the memory (130). When the operation of the water purifier starts, the water purifier control program may measure the temperature of an ice storage tank for generating cold water, generate status data of the ice storage tank, and control the path of refrigerant or hot gas discharged from a first evaporator included in an ice room based on the status data. For example, when the temperature of the ice storage tank is higher than a preset temperature, the water purifier control program may transfer the refrigerant discharged from the first evaporator for ice making to the second evaporator through a bypass line. For example, when the state of the ice storage tank is determined to be a frozen state, the water purifier control program may transfer the hot gas discharged from the first evaporator to the second evaporator to remove supercooling.

According to an exemplary embodiment, the memory (130) may perform a function of temporarily or permanently storing data processed by the control module (110). Here, the memory (130) may include a magnetic storage media or a flash storage media in addition to a volatile storage device that requires power to maintain stored information, but the scope of the present disclosure is not limited thereto.

The input module (120) can receive a water dispensing command or a single water dispensing command from the user through a button, a touch module, a jog dial, a touch display, a membrane, etc. In addition, the input module (120) can receive a desired setting value from the user, such as water temperature, the amount of water to be dispensed, etc.

The filter module may include various filters such as a hollow fiber membrane filter, a membrane filter, a compressed activated carbon filter, and may further include an ultraviolet lamp for sterilization.

The cooling module (150) can convert the filtered water into cold water or ice. The cooling module (150) can include an evaporator through which a refrigerant flows to perform heat exchange with the filtered water, a compressor for compressing the heat-exchanged refrigerant, and a condenser for condensing the compressed refrigerant. The cooling module (150) or the cooling system is described in detail in FIG. 2.

The hot water module (160) may include a heater and a hot water tank for heating filtered water.

The ice-making module (170) is a module for creating ice in a water purifier, and may include an ice-making tray and an evaporator for ice-making. The ice-making module (170) may share some of its configuration with the cooling module, or may be configured as a cooling system including a separate evaporator.

Figure 2 is a drawing for explaining a cooling system of a water purifier according to the present disclosure.

Referring to FIG. 2, the cooling system (200) may include a compressor (210), a condenser (220), a capillary tube (230), and an evaporator (240). The cooling system (200) may further include a filter module capable of filtering impurities contained in the incoming water or components related to the water purifier.

The compressor (210) can suck in and compress low-temperature, low-pressure refrigerant gas (G1) that absorbs heat from a cooled object in the evaporator (240) and evaporates to discharge high-temperature, high-pressure refrigerant gas (G2).

The condenser (220) can condense the refrigerant gas by releasing heat into the atmosphere by passing the surrounding air or cooling water as the high-temperature, high-pressure refrigerant gas (G2) from the compressor (210) circulates through the condensing coil, thereby generating refrigerant liquid (G3).

The capillary tube (230) can convert high temperature and high pressure refrigerant liquid (G3) into low temperature and low pressure refrigerant liquid (G4). The capillary tube (230) can lower the pressure of the refrigerant to expand it and evaporate the refrigerant liquid (G4) into low temperature and low pressure refrigerant gas (G1) inside the evaporator (240). The capillary tube (230) or the expansion valve can control the flow rate of the refrigerant circulating inside the evaporator (240) according to the cooling load.

The evaporator (240) is a heat exchange device in which low-temperature, low-pressure refrigerant liquid (G4) expanded in a capillary tube (230) absorbs latent heat of vaporization from a cooled object connected to the evaporator (240) and evaporates to exert a cooling effect. The refrigerant gas (G1) expanded and evaporated in the evaporator can be sucked into a compressor, recompressed, and then circulated.

Referring to FIG. 3, the water purifier (300) may include a compressor (310), a condensing module (320), a second valve (330), a first capillary (340), a second capillary (342), a first valve (350), an ice room (360), and an ice storage tank (370). The condensing module (320) may include a condenser (322) and a heat dissipation fan (324). The ice room (360) may include a first evaporator (362) and a first temperature sensor (364). The ice storage tank (370) may include a second evaporator (372) and a second temperature sensor (374).

The compressor (310) can suck in and compress low-temperature, low-pressure refrigerant gas that has absorbed heat from a cooled object in the evaporator (362, 372) and evaporated, and discharge high-temperature, high-pressure refrigerant gas.

The condenser (322) can condense the refrigerant gas to generate refrigerant liquid by releasing heat into the atmosphere by passing the surrounding air or cooling water when the high-temperature, high-pressure refrigerant gas from the compressor (310) circulates through the condensing coil. The heat dissipation fan (324) is positioned adjacent to the condenser (322) and can operate to smoothly release heat from the condenser into the atmosphere.

The second valve (330) may be a four-way valve. The second valve (330) may distribute the refrigerant liquid introduced from the condenser (322) to the first capillary tube (340) or the second capillary tube (342). The second valve (330) may deliver hot gas to the first evaporator (362) for deicing or ice removal. The water purifier (300) may sequentially deliver the hot gas delivered to the first evaporator (362) to the first valve (350) and the second evaporator (372) for ice removal in the ice storage tank. The first valve (350) and the inlet of the second evaporator may be connected by a bypass line.

The capillary tube (340, 342) can convert high-temperature, high-pressure refrigerant liquid into low-temperature, low-pressure refrigerant liquid. The capillary tube (340, 342) can play a role in reducing the pressure of the refrigerant to expand it and evaporate the refrigerant liquid into low-temperature, low-pressure refrigerant gas within the evaporator (362, 372). The capillary tube (340, 342) or the expansion valve can play a role in controlling the flow rate of the refrigerant circulating within the evaporator (362, 372) according to the cooling load.

The second capillary (342) can deliver refrigerant to the second evaporator (372) included in the ice storage tank (370). The first capillary (340) can deliver refrigerant to the first evaporator (362).

The water purifier (300) can save energy by utilizing the refrigerant used in the first evaporator (362) in the second evaporator (372) during the operation of the water purifier. For example, the water purifier (300) can measure the temperature of the ice storage tank (370) and, if the temperature is higher than a preset temperature, transfer the refrigerant used in the first evaporator (362) to the second evaporator (372) through a bypass line to additionally cool the ice storage tank (370).

The water purifier (300) can remove freezing or supercooling by utilizing the hot gas used in the first evaporator (362) in the second evaporator (372) during the operation of the water purifier. For example, the water purifier (300) can measure the temperature of the ice storage tank (370) and, if the temperature is lower than a preset temperature, transfer the hot gas used in the first evaporator (362) to the second evaporator (372) through a bypass line to remove freezing or supercooling in the ice storage tank (370). The water purifier (300) can determine whether freezing occurs by recognizing the operating status of the stirring motor included in the ice storage tank (370).

The water purifier (300) can utilize temperature information measured by the second temperature sensor (372) included in the ice storage tank (370) and temperature information measured by the first temperature sensor (364) included in the ice room (360) in the process of controlling the first valve (350) to utilize the bypass line. The first temperature sensor (364) can measure the temperature of the refrigerant or hot gas discharged from the first evaporator (362). For example, if the temperature of the refrigerant measured by the first temperature sensor (364) is lower than a preset temperature, the water purifier (300) can determine that it is appropriate to cool the ice storage tank (370) and transfer the refrigerant to the second evaporator (372) through the bypass line. For example, if the temperature of the hot gas measured by the first temperature sensor (364) is higher than a preset temperature, the water purifier (300) may determine that it is appropriate to relieve freezing or supercooling of the ice storage tank (370) and may transmit the hot gas to the second evaporator (372) through the bypass line.

The first temperature sensor (364) may be positioned adjacent to the discharge port of the first evaporator (362), and the location of the first temperature sensor (364) is not limited thereto, and may be appropriately positioned inside or outside the ice room (360) to measure the temperature of the ice room (360) or the temperature of the refrigerant.

The second temperature sensor (372) can measure the temperature of the ice storage tank (370) or the second evaporator (372). For example, if the temperature measured by the second temperature sensor (372) is higher than a preset temperature, the water purifier (300) determines that additional cooling is necessary and can transfer the refrigerant discharged from the first evaporator (362) to the second evaporator (372) through a bypass line. For example, if the temperature measured by the second temperature sensor (372) is lower than a preset temperature, the water purifier (300) determines that the state of the ice storage tank (370) is frozen or supercooled and can transfer the hot gas to the second evaporator (372) through a bypass line.

The three-way valve (480) and the inlet of the cold water evaporator (462) may be connected through a bypass line. The water purifier (400) may control the three-way valve (480) according to the state of the ice room or ice storage tank (460) to deliver refrigerant or hot gas to the cold water evaporator (462) included in the ice storage tank (460).

Figure 6 is a flowchart for explaining the operating method of a water purifier according to the present disclosure.

The water purifier can measure the temperature of an ice storage tank for generating cold water during operation and generate status data of the ice storage tank (S110). For example, the water purifier can determine that additional cooling is required if the temperature of the ice storage tank is in a first temperature range that is higher than a preset temperature. The water purifier can determine that the ice storage tank is in a freezing or supercooling state if the temperature of the ice storage tank is in a third temperature range that is lower than the preset temperature. In addition to the temperature, the water purifier can determine the freezing or supercooling state based on the operating status of the stirring motor. The water purifier can determine that the ice storage tank is in a state suitable for generating cold water if the temperature of the ice storage tank is in a second temperature range that is lower than the first temperature range and higher than the third temperature range.

The water purifier can determine whether the ice storage tank temperature is higher than a preset temperature (S120). If the ice storage tank temperature is lower than the preset temperature, the water purifier can repeat the generation of status data without any additional operation because there is no problem in generating cold water.

The water purifier can determine whether the ice making cycle is in operation when the ice storage tank temperature is higher than a preset temperature (S130).

The water purifier can transfer the refrigerant discharged from the first evaporator, which is an ice-making evaporator, to the compressor when the ice-making cycle is not in operation (S140).

When the ice-making cycle is in operation, the water purifier can transfer the refrigerant discharged from the first evaporator, which is an ice-making evaporator, to the second evaporator, which is a cold water evaporator (S140).

Referring to FIGS. 3 and 6 together, if the ice storage tank temperature is higher than a preset temperature and there is no need to perform an ice-making operation, the water purifier can control the second valve (330) to sequentially transfer the refrigerant to the second capillary tube (342) and the second evaporator (372) to cool the ice storage tank (370). If the ice storage tank temperature is higher than a preset temperature and an ice-making operation is performed, the water purifier can control the second valve (330) to sequentially transfer the refrigerant to the first capillary tube (340) and the first evaporator (362) to perform an ice-making operation in order to effectively utilize the refrigerant. After performing the ice-making operation, the water purifier can control the first valve (350) again to recycle the refrigerant in the second evaporator (372).

Figure 7 is a flowchart for explaining the operating method of a water purifier according to the present disclosure.

The water purifier can measure the temperature of the ice storage tank for generating cold water during operation and generate status data of the ice storage tank (S210). The water purifier can determine that the temperature of the ice storage tank is in a third temperature range lower than a preset temperature, and is in a frozen or supercooled state. In addition to the temperature, the water purifier can determine the frozen or supercooled state based on the operating status of the stirring motor.

The water purifier can determine whether the state of the ice storage tank is frozen or supercooled (S220). The water purifier can determine that the state is frozen or supercooled if the temperature of the ice storage tank is in the third temperature range below the preset temperature. In addition to the temperature, the water purifier can determine the state is frozen or supercooled based on the operating state of the stirring motor.

The water purifier can repeat the generation of status data if the ice storage tank status is not frozen or supercooled.

The water purifier can determine whether the ice making cycle is in operation when the ice storage tank status is frozen or supercooled (S230).

The water purifier can use hot gas only in the first evaporator, which is an ice-making evaporator, and end the ice-removing step or the hot gas cycle when the ice-making cycle is not in operation (S240).

When the ice-making cycle is in operation, the water purifier can circulate hot gas to the first evaporator, which is an ice-making evaporator, for deicing, etc., and then deliver it to the second evaporator, which is a cold water evaporator, through a bypass line (S250).

Through the present disclosure, the water purifier can save energy by secondary cooling the ice storage tank through the residual heat generated during the ice-making operation, and can eliminate the freezing or supercooling state of the ice storage tank by recycling the hot gas.
