Description

    CROSS-REFERENCE TO RELATED APPLICATIONS
  • This application claims priority from Korean Patent Application No. 10-2014-0157384, filed on Nov. 12, 2014 in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference in its entirety.
  • BACKGROUND
  • 1. Field
  • Apparatuses and methods consistent with the present invention relate to an air conditioner and more particularly to an air conditioner in which a lower portion of a stand type indoor unit is supported by a frame structure and a main body is inclined backward at a predetermined angle so as to increase an air-blast distance of discharged cool air.
  • 2. Description of the Related Art
  • In general, an air conditioner is configured with a compressor, a condenser, an expansion device, and an evaporator. An air conditioner cools or warms indoor air using a refrigeration cycle of a refrigerant or purifies indoor air in order to promote a pleasant indoor environment for a user, and is largely classified into a separation type air conditioner and an integration type air conditioner.
  • The separation type air conditioner is configured by installing a cooling device/heat sink in an indoor unit, installing a heat sink/cooling device and a compressor in an outdoor unit, and connecting the indoor unit and the outdoor unit that are separated from each other through a refrigerant pipe. The integration type air conditioner is configured by integrating cooling and heat-dissipating functions in a single body and is disposed in a hole formed in a wall of a house or in a window by using a fixture.
  • Recently, a stand type air conditioner configured by installing an indoor unit on the floor so as to discharge air sucked in through a suction port via rotation of a fan through a heat exchanger has been largely used.
  • Such a conventional stand type indoor unit is put in the form of a vertical cabinet on the floor, and a lower portion of stand type indoor unit is mainly used to suck in air, used to accommodate an air cleaner, or used for assembly of internal components.
  • Accordingly, the conventional stand type indoor unit has a large volume such that indoor spaces of a building may not be effectively used and also does not provide a fine view due to uniform designs.
  • In addition, the conventional stand type indoor unit has a problem in terms of a short air-blast distance of cool air since a main body is approximately vertically put on the floor and sends cool air squarely. To overcome this, wind is adjusted in an upward direction using a blade of a discharge port. However, a discharging direction of cool air and a direction of the blade do not match each other, and resistance is generated in air current that reduces intensity of the air blast, and thus there is a limit to sending cool air far.
  • In addition, for installation of the conventional stand type indoor unit, the connection pipe extends from the indoor unit to a wall surface and also a surface of the connection pipe is wrapped by a tape or the like, thereby degrading an outer appearance.
  • SUMMARY

  • The fan 125 sends air introduced into the housing 110 out of the air conditioner 100, is rotatably coupled to the driving motor, and is surrounded by the duct 124.
  • At least one duct 124 is formed in a circular form so as to surround the fan 125 and forms an air path such that air sucked in by the fan 125 flows toward the discharge port 121 a.
  • The heat exchanger 129 is disposed between the fan unit 120 and the suction port 130 and evaporates (or condenses) refrigerants to adsorb heat from air introduced through the suction port 130 or to transfer heat to air introduced from the suction port 130. The heat exchanger 129 is fixed to the main body M1 by a fixture (not shown) disposed at one side of upper and lower ends of an internal portion of the housing 110.
  • A drain hose 161 for draining condensation liquid water generated in the heat exchanger 129 and a refrigerant pipe for connection between the indoor heat exchanger 129 and an outdoor heat exchanger (not shown) are connected to one end of the heat exchanger 129.
  • The suction port 130 is disposed in a rear portion of the air conditioner 100 so as to guide outdoor air to be introduced into the air conditioner 100. At least one suction port 130 may be formed in a rear portion, a lateral portion, or the like of the rear panel 113.

  • The cabinet 160 is disposed below the main body M1 and connected to and supported by the support B1. The cabinet 160 is configured in the form of substantial rectangular parallelepiped in order to couple a front frame 140 and a rear frame 150 to a front portion and a rear portion, respectively and includes the drain hose 161, the refrigerant pipe 163, a cabinet cover 165, a pipe hole 167, a main body coupler 168, and a front frame coupler 169.
  • The drain hose 161 is used to externally discharge condensation liquid water formed by condensing and dropping moisture in air out of the air conditioner 100 during air cooling in the heat exchanger 129 when the air conditioner 100 performs a cooling operation for cooling air and is connected to the pipe 170 inside the cabinet 160.
  • The refrigerant pipe 163 is used for connection between the indoor heat exchanger 129 and the outdoor heat exchanger (not shown), is accommodated by the pipe 170 together with the drain hose 161 in the cabinet 160, and extends out of the air conditioner 100.
  • The cabinet cover 165 may cover lateral and rear surfaces of the cabinet 160. In addition, the pipe hole 167 to pass the pipe 170 therethrough is formed in the rear surface of the cabinet cover 165, and an upper end of the rear frame 150 is fixedly coupled to the rear surface of the cabinet cover 165.
  • The pipe hole 167 may allow the pipe 170 that is formed to pass through an internal portion of the cabinet 160 and accommodates the drain hose 161 and the refrigerant pipe 163 therein to extend out of the air conditioner 100 and may be formed at an arbitrary position of the rear surface of the cabinet cover 165 according to a shape of the rear frame 150.
  • The main body coupler 168 may be formed at an upper portion of the cabinet 160 so as to fixedly couple the main body M1 and the cabinet 160 and may be coupled to the main body M1 with a screw coupling structure or a male and female coupling structure, but are not limited thereto.
  • The front frame coupler 169 may fixedly couple a front portion of the cabinet 160 and the front frame 140 and may be coupled to the front frame 140 with a screw coupling structure, but is not limited thereto.
  • The support B1 includes the front frame 140 coupled to a front portion of the cabinet 160 and the rear frame 150 coupled to a rear portion of the cabinet 160.
  • The air conditioner 100 according to the present invention is configured in such a way that the support B1 supports the main body M1 with a frame structure. Accordingly, although the same height as a conventional air conditioner is maintained, an open space may be formed in a portion below the air conditioner 100 so as to use a lower space, to easily clean the floor, to achieve an excellent outer appearance, and to also allow an indoor space to look big.
  • Referring to FIGS. 2A and 2B, the front frame 140 is coupled to the front portion of the cabinet 160 to support the main body M1 and the cabinet 160, and may further include a front frame cover 141. The front frame 143 includes a case frame 143 a, a reinforcing member 143 b, a lateral surface cover 143 c, a lower surface cover 143 d, a reinforcing frame 143 e, and a front frame coupler 143 f.
  • The front frame cover 141 is coupled to an upper portion of the front frame 140 to cover the front frame 140 and the cabinet 160, thereby forming an external appearance of the air conditioner 100. The front frame cover 141 may be coupled to the front frame 140 by a male and female coupler 141 a or a screw 141 c but is not limited thereto. An outer appearance 141 b of the front frame cover 141 may be shaped like a quadrangle but is not limited thereto.
  • The case frame 143 a forms a basic frame of a front frame 143 and is coupled to a front portion of the cabinet 160. A lateral surface and lower surface of the case frame 143 a may be curved so as to accommodate the reinforcing member 143 b.
  • The reinforcing member 143 b is inserted into the case frame 143 a so as to reinforce the intensity of the case frame 143 a. Accordingly, load of the main body M1 and the cabinet 160 may be sufficiently supported by the support B1 that is thinned compared with a prior art, and also a stable structure may be formed with respect to bending, shear, and distortion. The reinforcing member 143 b may be formed as an iron bracket but is not limited thereto.
  • The lateral surface cover 143 c and the lower surface cover 143 d cover the case frame 143 a and the reinforcing member 143 b and form external surfaces of the lateral and lower surfaces of the front frame 143.
  • The reinforcing frame 143 e may be formed at a portion corresponding to the middle of the height of the front frame 143 so as to fix the front frame cover 141 or reinforce the front frame 143 with respect to bending and distortion.
  • The front frame couplers 143 f are formed at opposite sides of the upper portion of the front frame 143 so as to fixedly couple the front frame 143 to the cabinet 160.
  • Referring to FIG. 2A, the rear frame 150 includes a pair of vertical frames 151 a and 151 b, a horizontal frame 151 c, a rear frame cover 151 d, a rear frame coupler 151 e, and a rear frame pipe hole 151 f.
  • The pair of vertical frames 151 a and 151 b is fixedly coupled to the rear portion of the cabinet cover 165 by the rear frame coupler 151 e and is inclinedly disposed toward the rear surface of the cabinet 160. In addition, the rear frame 150 may not include the horizontal frame 151 c for connecting lower ends of the pair of vertical frames 151 a and 151 b. When the rear frame 150 does not include the horizontal frame 151 c, the pair of vertical frames 151 a and 151 b support the main body M1 and the cabinet 160 with a column form. The rear frame cover 151 d forms the rear frame pipe hole 151 f through which the pipe 170 passes.
  • In the air conditioner 100 according to the present invention, the front frame 140 is inclined backward by as much as a preset angle α, and as the front frame 140 is inclined backward, the main body M1 is also inclined backward by as much as an angle at which the front frame 140 is inclined. Accordingly, the air conditioner 100 according to the present invention may discharge cool air upward by as much as an angle β that corresponds to or is the same as the inclination angle α based on an axis that is parallel to the ground so as to send the discharged air farther than a vertically oriented conventional air conditioner, and a discharging direction of air corresponds to an inclination direction of the air conditioner 100, thereby minimizing friction of air.
  • An angle at which the air conditioner 100 is inclined backward may be equal to or greater than 1 degree or equal to or less than 9 degrees. For example, the inclination angle may be 3 degrees but is not limited thereto.
  • FIGS. 3A to 3C are diagrams illustrating first to third modification examples of the support B1 according to the first embodiment of the present invention. The first to third modification examples are almost the same as the basic configuration of the first embodiment illustrated in FIGS. 1A to 2B except for a portion of the rear frame 150. In the first to third modification examples, the same components as those of the first embodiment are denoted by the same reference numeral.
  • FIG. 3A illustrates the first modification example of the support B1 according to the first embodiment of the present invention. The rear frame 153 includes a pair of vertical frames 153 a and 153 b. An upper end of each of the pair of vertical frames 153 a and 153 b may be coupled to the cabinet 160 and inclined toward a rear surface of the cabinet 160 at a preset angle in order to prevent the air conditioner 100 from falling down.
  • FIG. 3B illustrates the second modification example of the support B1 according to the first embodiment of the present invention.

The support 147 includes a pair of vertical frames 147 a, a pair of horizontal frames 147 b, and a connection frame 147 c.
  • The pair of vertical frames 147 a is coupled to opposite sides of a front portion of the cabinet 160 and configured to incline the main body M1 backward at the same angle as a preset angle. The pair of vertical frames 147 a are formed at the front portion of the support B1 and configured by extending downward such that respective lower ends of the pair of vertical frames 147 a are connected to the pair of horizontal frames 147 b.

  • Along with rotation of the fan 125 formed in a fan unit 124, external air is introduced through a suction port 113 formed in a rear portion of the air conditioner 100. In this case, the external air becomes cool air by adsorbing heat from the external air through the heat exchanger 129, and the cool air is discharged toward the front portion of the air conditioner 100 through the fan 125.
  • Since the main body M1 is inclined backward by as much as a preset angle, cool air is discharged upward based on an axis in parallel to the ground at an angle corresponding to the above angle or at the same angle as the above angle. Accordingly, cool air is discharged farther than the conventional air conditioner so that the efficiency of the air conditioner 100 is increased.
  • The heat exchanger 129 generates condensation liquid water during heat absorption, and the condensation liquid water is collected by a drain hose 129 and externally discharged through the pipe 170.

An operation of the air conditioner 200 according to the second embodiment of the present invention is the same as the operation of the air conditioner 100 according to the first embodiment of the present invention. In the second embodiment, the same components as those of the first embodiment are denoted by the corresponding reference numerals.
  • In response to power being applied to the air conditioner 200, a controller (not shown) may transmit a control command according to a driving mode selected by a user so as to drive the air conditioner 200.
  • Along with rotation of the fan 225 formed in a fan unit 224, external air is introduced through a suction port 213 formed in a rear portion of the air conditioner 200. In this case, the external air becomes cool air by absorbing heat from the external air through the heat exchanger 229, and the cool air is discharged toward the front portion of the air conditioner 200 through the fan 225.
  • Since the main body M2 is inclined backward by as much as a preset angle, cool air is discharged upward based on an axis in parallel to the ground at an angle that corresponds to or is the same as the above angle. According to properties whereby cool air moves relatively downward in a space, when cool air is discharged upward at a predetermined angle, cool air may be discharged farther than the conventional air conditioner.
  • The heat exchanger 229 generates condensation liquid water during heat absorption, and the condensation liquid water is collected by the drain hose 229 and externally discharged through the pipe 270.
  • The foregoing exemplary embodiments and advantages are merely exemplary and are not to be construed as limiting the present invention. Also, the description of the exemplary embodiments of the present invention is intended to be illustrative, and not to limit the scope of the claims, and many alternatives, modifications, and variations will be apparent to those skilled in the art.
