Definitions

  • the present invention relates to hot water apparatus capable of preventing a heater from being reversely heated by hot water, and a refrigerator having the same.
  • a refrigerator serves as an apparatus for storing food items in a fresh or frozen state for a predetermined time as a refrigerant repeatedly passes through a refrigerating cycle for compression, condensation, expansion and evaporation.
  • Such refrigerator is considered as one of necessities.
  • a recent large-sized refrigerator is provided with a dispenser through which ice or water stored therein is taken out without causing a user to open a door. This may prevent cool air inside the refrigerator from leaking to the outside, and may enhance a user's convenience.
  • a dispenser for supplying hot water (hereinafter, will be referred to as hot water supplying dispenser) is being widely used at an office or other public facility, because it allows a user to conveniently make a cup of tea thereby.
  • a hot water pipe is connected to a hot water taking-out pipe and a water supply pipe of the dispenser. And, a heater for heating the hot water pipe is installed at the door.
  • the water is introduced to the hot water pipe via a switching valve of the water supply pipe. Then, the water is instantaneously heated via the heater, and is discharged to the dispenser via the hot water taking-out pipe.
  • the heater may be formed in various manners. Recently, a so-called 'heat plate contact type heater' is being developed.
  • a water container of a wide box shape has an opening covered by a heat plate having thermal lines therein, so that water contained in the water container can be heated by contacting the heat plate.
  • a water path is formed in a zigzag shape in the water container so as to increase a contact area between the water contained in the water container and the heat plate.
  • the heater of the hot water supplying dispenser has the following problems.
  • the heater of the dispenser is designed to discharge hot water at temperature of about 95°C. If the heater discharges hot water at temperature more than 100°C, a heat jumping phenomenon occurs from the heater. This may cause the thermal lines to have drastic temperature increase, resulting in damage of the thermal lines.
  • KR 2004 0074442 A describes a hot water supply apparatus of a refrigerator which is composed of a filter, a dispenser supplying water from the filter out of the refrigerator, and a heater installed in the end of a pipe.
  • Patent specification WO 2004/113800 A2 discloses a hot water supply apparatus as defined in the preamble of claim 1.
  • an object of the present invention is to provide a hot water supplying device capable of preventing overheating of a heater by properly cooling hot water to be discharged, using low-temperature water introduced into the heater.
  • the temperature stabilizing unit is formed by arranging an inlet and an outlet of a water container close to each other. Under this configuration, cool water introduced into a water path of the water container via the inlet serves to cool hot water to be discharged via the outlet of the water container. This may prevent the hot water from being overheated to temperature more than a preset value. As a result, this may prevent damage of thermal lines of a heating element, due to overheating, the overheating occurring as water inside the water container is overheated.
  • FIG. 1 is a frontal view of a refrigerator having a hot water supply apparatus according to the present invention
  • FIG. 2 is a disassembled perspective view of the water container and heating element of the hot water supply apparatus of the refrigerator of FIG. 1
  • FIG. 3 is an assembled perspective view of the water container and heating element of FIG. 2
  • FIG. 4 is a planar view of the water container and heating element of FIG. 2 .
  • a refrigerator having a heater for a dispenser comprises a freezing chamber door 1 configured to open and close a freezing chamber, a cooling chamber door 2 configured to open and close a cooling chamber, a water supply pipe 3 configured to supply water from the outside, a heater 100 disposed in the freezing chamber door 1, and configured to heat water supplied from the water supply pipe 3, and a dispenser 4 configured to discharge hot water heated by the heater 100 or cool water.
  • a switching valve 7 configured to distribute water supplied from the water supply pipe 3 to a cool water pipe 5 or a hot water pipe 6 is provided at an upper end of the water supply pipe 3.
  • the heater 100 may be installed above or below the dispenser according to a type of the refrigerator. In this embodiment, the heater is installed below the dispenser.
  • the heater 100 includes a water container 110 having a water path 111 including an inlet 112 and an outlet 113, and a heating element 120 coupled to the water container 110 so that water flowing along the water path 111 of the water container 110 can be heated.
  • the water container 110 is formed in a rectangular parallelepiped shape. And, the water path 111 is formed on one side surface of the water container 110, i.e., a contact surface 110a in a zigzag shape, or a spiral shape (not shown).
  • the inlet 112 and the outlet 113 of the water path 111 are formed on the same side surface of the water container 110 close to each other, so that water introduced into the inlet can be heat-exchanged with water discharged from the outlet 113.
  • the water path 111 is formed on an entire region of the contact surface 110a, one side surface of the water container 110, so that a single water path 111 can be implemented from the inlet 112 to the outlet 113.
  • the water path 111 is formed so that a first section (A) from the inlet 112 to an intermediate portion thereof can be heat-exchanged with a second section (B) from the intermediate portion thereof to the outlet 113.
  • the first section (A) has a bent section from the inlet 112 to a predetermined part, but has a linear section at the rest part.
  • the linear section passes through the edge of the water container 110.
  • the second section (B) is bent several times in a zigzag form so as to increase a contact area to the heating element 120.
  • a temperature stabilizing unit 115 is implemented by forming an outlet section (D) of the second section (B) in parallel to an inlet section (C) of the first section (A), i.e., the bent section of the first section (A). This is in order to allow cool water introduced via the inlet section (C) of the first section (A) to be heat-exchanged with hot water discharged via the outlet section (D) of the second section (B).
  • the water path 111 may be configured such that a linear distance (L1) from the inlet 112 to the outlet 113 is shorter than a linear distance from the inlet 112 or the outlet 113 to an intermediate portion of the inlet 112 and the outlet 113.
  • a linear distance indicates a distance from the outlet to an intermediate portion of the inlet 112 and the outlet 113.
  • the water path 111 may be configured such that an interval between at least part of the first section (A) and at least part of the second section (B) in a vertical direction is greater than an interval between the inlet 112 and the outlet 113 in a vertical direction.
  • the heating element 120 may be formed to have an area large enough to accommodate therein the entire part of the water path 111 of the water container 110. More specifically, the heating element 120 may be formed in a cubic or thin plate shape having the same area as the contact surface 110a of the water container 110. According to the invention, the heating element is formed in a plate shape.
  • the heating element 120 may be provided with thermal lines 121 mounted therein, in correspondence to an entire area of the water path 111 of the water container 110, i.e., an area including the inlet section (C) of the first section (A) and the outlet section (D) of the second section (B). That is, the thermal lines 121 may be installed in the heating element 120 so as to have an area corresponding to the water container 110 including the temperature stabilizing unit 115.
  • the refrigerator having the heater according to the present disclosure has the following advantages.
  • water is guided to the inside of the refrigerator via the water supply pipe 3. Then, the water guided to the inside of the refrigerator is heated via the heater 100 disposed inside the refrigerator thus to be stored as hot water, or to be discharged out through the dispenser 4.
  • the water path 111 is formed in a zigzag shape so that water passing through the heater 100 can be smoothly heat-exchanged with the heater 100. This may cause the water path 111 to be blocked, or water inside the water path 111 to have temperature increase to temperature more than a preset value, i.e., 95°C. As a result, steam is generated to heat the heating element 120. This may cause the thermal lines 121 mounted in the heating element 120 to have drastic temperature increase, resulting in damage of the thermal lines 121.
  • the temperature stabilizing unit 115 is provided by arranging the inlet 112 and the outlet 113 of the water container 110 close to each other.
  • cool water introduced to the water path 111 of the water container 110 from the hot water pipe 6 via the inlet 112 serves to cool hot water to be discharged to a hot water taking-out pipe 8 via the outlet 113 of the water container 110. This may prevent the hot water from being overheated to temperature more than a preset value.
  • this may prevent damage of the thermal lines 121 of the heating element 120 due to overheating, the overheating occurring as water inside the water container 110 is overheated.
  • the thermal lines 121 of the heating element 120 are arranged to correspond to the entire region of the water path 111 of the water container 110, i.e., the water path 111 including the temperature stabilizing unit 115.
  • overheating of water is prevented by preventing the thermal lines 121 of the heating element 120 from being accommodated in part of the water path 111 of the water container 110, i.e., by allowing the temperature stabilizing unit 115 of the water path 111 not to correspond to the thermal lines 121.
  • the water container 110 is formed in the same shape as that of the aforementioned embodiment.
  • the heating element 120 is arranged such that the thermal lines mounted therein do not include the inlet section (C) and the outlet section (D) of the water container 120. Under this configuration, water inside the outlet section (D) is not rapidly heated, but slowly heated by the thermal lines 121. This may allow water to maintain a proper temperature at a section where overheating easily occurs.
  • the heater 100 is formed in a plate shape.
  • the heater 200 is formed in a tube shape.
  • the heater 200 is formed in a tube shape where the water container 210 has an inner space 211 so as to form a water path. And, heating elements 220 are wound, in a band shape, on an outer circumferential surface of the water container 210.
  • An upper end of the inner space 211 of the water container 210 is open, and a cap 212 is coupled to the opening.
  • An inlet 213 through which a hot water pipe (not shown) is communicated with the inner space 211 is formed at a central region of the cap 212.
  • an outlet 214 through which a hot water taking-out pipe (not shown) is communicated with the inner space 211 is formed close to the inlet 213.
  • the inlet 213 is extended in a tube shape so that water introduced via the hot water pipe 6 can be guided to the bottom of the inner space 211 of the water container 210. And, an exit of the inner space 211 is inserted into the inlet 213 by a particular depth.
  • An entrance of the outlet 214 is positioned on the bottom surface of the cap 212 such that water introduced into the inner space 211 via the inlet 213 is sufficiently heat-exchanged with the heating element 220 at the inner space 211.
  • a temperature stabilizing unit 215 may be implemented at the cap 212 by forming a water path 216 from the inlet 213 to the outlet 214 in a zigzag or spiral shape.
  • the heating element 220 may be provided on an entire region of an outer circumferential surface of the water container 210, i.e., a region of the cap 212.
  • the heating element 220 may not be provided on the region of the cap 212.
  • the water container is vertically installed such that a cover is positioned thereabove. This may cause hot water to rapidly upward move, resulting in a higher possibility that a heat pumping phenomenon occurs at the upside, than in the aforementioned plate-shape heater.
  • overheating of the heater can be prevented by forming the temperature stabilizing unit at the cover.
  • the heater described above may be also applicable similarly to a water purifier and the like as well as the foregoing refrigerator. However, this does not lie within the scope of the present invention.
