Definitions

  • the present invention relates to air conditioners.
  • JP 7-293929 A there is described an air conditioner.
  • a temperature sensor and a humidity sensor are disposed respectively on the side facing an air inlet in a heat exchanger disposed in an air passage.
  • the temperature sensor and the humidity sensor are held integrally by a holder and these can be installed at a time.
  • the temperature sensor is disposed above the humidity sensor and the holder is disposed above a secondary filter provided at the air inlet of a grille. Accordingly, not only the temperature sensor, but also the humidity sensor hardly comes into contact with the secondary filter and a frame thereof, and even when the humidity sensor comes into contact with the filter and the frame, it is hardly impaired, since the outer part of the humidity sensor is formed of soft resin.
  • a further conventional air conditioner has a temperature sensor mounted in front of a heat exchanger by means of a fitting (see JP 9-178305 A , for example).
  • the temperature sensor can precisely detect the temperature of air taken in from a room while the air conditioner is operating because the sensor is located in an air passage.
  • a multi-type air conditioner including two or more indoor units when an indoor unit is out of operation while other indoor units are operating, a refrigerant is made to circulate even in the out-of-operation indoor unit to prevent pool of the refrigerant therein.
  • the temperature sensor in the out-of-operation indoor unit cannot detect the indoor temperature correctly under the influence of the temperature of the heat exchanger.
  • An object of the present invention is to provide an air conditioner capable of correctly and precisely detecting the indoor temperature with a simple structure even when the air conditioner is out of operation.
  • an air conditioner according to the present invention includes:
  • the temperature sensor is located in a position between the heat exchanger and the connection piping, and moreover the temperature sensor is shielded or blocked from the heat exchanger and the connection piping by the cover. Therefore, it is possible to reduce the influence of radiant heat from the heat exchanger and the connection piping irrespective of whether the air conditioner is in operation or out of operation. Also, while the air conditioner is operating, air circulates through the air passage between the front panel and the front grill where the temperature sensor is located. The temperature sensor, therefore, can correctly detect the temperature. That is, the air conditioner achieves correct detection of the indoor temperature with simple arrangement even when it is out of operation.
  • the cover constitutes a part of the front grill.
  • the cover for blocking radiant heat from the heat exchanger and/or the connection piping constitutes part of the front grill, portions of the front grill around the cover are also usable as a heat shield. As a result, the heat blocking effect may be enhanced.
  • the temperature sensor is on a plane located forward of a front-side plane of the heat exchanger.
  • the temperature sensor is located on the plane forward of the front-side plane of the heat exchanger, the temperature sensor is distant from the heat exchanger and/or the connection piping. This contributes further to the reduction of the influence of radiant heat from the heat exchanger and/or the connection piping.
  • the present invention can achieve an air conditioner capable of correctly detecting the indoor temperature with a simple arrangement even while the air conditioner is out of operation.
  • the cover blocking the radiant heat from the heat exchanger and/or the connection piping constitutes a part of the front grill, portions around the cover of the front grill are also usable as a heat shield. As a result, the heat blocking effect is enhanced.
  • the temperature sensor is located on a plane forward of the front-side plane of the heat exchanger, the temperature sensor is distant from the heat exchanger and/or the connection piping. This contributes further to the reduction of the influence of radiant heat from the heat exchanger and/or the connection piping.

  • the control unit 11 is made up of a microcomputer, an input/output circuit and the like.
  • the control unit 11 controls the compressor 1, the four-way directional control valve 2, the electric expansion valve 4, the indoor fan 7, etc.
  • the compressor 1, the four-way directional control valve 2, the outdoor heat exchanger 3, the electric expansion valve 4, the accumulator 6, the outdoor fan 7, and the control unit 11 are components of an outdoor unit 10.
  • the indoor heat exchanger 5, the indoor fan 8, and the temperature sensor 9 are components of an indoor unit 20.
  • the refrigerant circulates through the refrigerant circuit which is formed by the compressor 1, the indoor heat exchanger 5, the electric expansion valve 4, the outdoor heat exchanger 3 and the accumulator 6. Indoor air is circulated through the indoor heat exchanger 5 by the indoor fan 8 to thereby heat a room.
  • the four-way directional control valve 2 is switched to a position shown by a dotted line.
  • the refrigerating cycle is implemented by circulation of the refrigerant in order of the compressor 1, the outdoor heat exchanger 3, the electric expansion valve 4, the indoor heat exchanger 5, and the accumulator 6.
  • Fig. 2 shows a perspective view of the indoor unit 20 of the air conditioner.
  • the indoor unit 20 has a base frame 21, a front grill 22 and a front panel 23, as shown in Fig. 2 .
  • the base frame 21, which is an example of the casing, has a generally rectangular shape whose rear side is mounted on an indoor wall surface.
  • the front grill 22 is fitted to a front side of the base frame 21 and has a generally rectangular-shaped opening 22c at its front face. Also, the front panel 23 is fitted so as to cover the opening 22c of the front grill 22.
  • An upper side outlet 22a is provided in an upper part of the front grill 22.
  • a lower side outlet 22b is provided in a lower part of the front grill 22.
  • the upper side outlet 22a of the front grill 22 is equipped with a flap 24.
  • the flap 24 rotates during cooling and heating operations to respectively blow off cool and warm air through the upper side outlet 22a in an obliquely upward and forward direction. At the time of stoppage, the flap 24 covers the upper side outlet 22a, as shown in Fig. 2 .
  • the front panel 23 is provided with an upper side inlet 23a at its upper part.
  • a lower side inlet 23b is provided at a lower part of the front panel 23.
  • lateral inlets 23c are provided at the right and left sides of the front panel 23 ( Fig. 2 shows only the right-side inlet).
  • Fig. 3 shows a perspective view of the floor standing type indoor unit 20 of the air conditioner from which the front panel 23 has been removed, wherein components same as those shown in Fig. 4 are denoted by the same reference numbers in Fig. 4 .
  • a sensor section 31 protruding forward from the right side of the front grill 22.
  • a temperature sensor 9 is placed in this sensor section 31.
  • the temperature sensor 9 is at a position not confronting the indoor fan 8 as seen from the front side.
  • a humidity sensor may be placed together with the temperature sensor 9 in the sensor section 31.
  • the sensor section 31 is generally cubical in shape and has slits at each of its five sides, namely all sides other than the bottom that faces the front grill 22. Also, a board 51 (shown in Figure 5A and Figure 5B ) mounted with the temperature sensor 9 is fixed to the bottom of the sensor section 31 so that the back side of the temperature sensor 9 is covered or shielded by the board. In this way, the temperature sensor 9 is shielded from radiant heat coming from the indoor heat exchanger 5 and/or the connection pipings L1, L2 (shown in Figures 5A and 5B ). Thus, the indoor temperature can be detected precisely by the temperature sensor 9 while the air conditioner is out of operation.
  • Fig. 4 shows a sectional view of the indoor unit 20 of the air conditioner.
  • the reference numeral 31 indicates the sensor section.
  • a motor 26 is fixed onto a generally central portion of the base frame 21.
