Description

  BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a blower-equipped radiation type cooling and heating apparatus using a radiation panel as a heater and a cooler.

  The conventional radiation panel is mainly used as a heater by circulating hot water. On the other hand, in recent years, since it came to be able to obtain cold water by energy saving with high-performance heat pump, it is tried to circulate cold water to the said radiation panel and to utilize as a cooler.

  The water receiving tray 3 is a tray for receiving condensation water generated on the surface of the radiation panel 2 when circulating liquid having a temperature lower than the air temperature around the radiation panel 2 is circulated. Is located in The water receiving tray 3 in the present embodiment is provided with a drain 31 for drainage at a substantially central position of the bottom surface. Further, the bottom surface is formed in a funnel shape having an inclined surface which is lowered toward the drainage port 31 in order to facilitate the condensation water to flow down to the drainage port 31 side.

  The water receiving tray 3 may be called a "drain pan", but in the present invention, it will be described as being included in the concept of the water receiving tray 3.

  The panel fan 4 is for blowing heat from below to the radiation panel 2 to improve the heat exchange efficiency of the radiation panel 2. As shown in FIGS. 4 and 5, the panel fan 4 of the present embodiment is mainly composed of a blower fan 5 for generating wind power and a fan case 6 in which the blower fan 5 is built.

  The blower fan 5 mainly has a rotary wing 51 and a rotary motor (not shown) for rotating the rotary wing 51. The rotary wing 51 is formed in a cylindrical shape that can be incorporated in the elongated fan case 6, and a plurality of spirally formed blades 52 are provided around the rotary wing 51. For example, a rotor used for blowing air from an air conditioner can be used as the long rotor 51.

  The rotary motor connects the shaft of the rotary blade 51 to its rotary shaft, and as shown in FIG. 4, changes the number of rotations of the power on / off switch 53 and the rotary blade 51 to change the strength of the air flow. And a strong / weak switch 54 for switching the

  In addition, the ventilation fan 5 is not limited to a long thing, As shown in FIG. 6, you may select suitably from the fan used with a dryer etc., a propeller type fan, etc., for example.

  The fan case 6 incorporates the blower fan 5, and in the present embodiment, side plates 61 provided on the front, back and left and right sides, a top plate 62 covering the upper side of each side plate 61, and each side plate It is formed in a substantially box-like shape of a long shape by a bottom plate 63 which covers the lower side of 61. Further, in the fan case 6, an air inlet 7 for drawing air into the air blowing fan 5 and an air blowing hole 8 for air blowing to the radiation panel 2 are opened.

  The intake port 7 is formed in the side plate 61 provided on any one side of the front, back and left and right sides, and in the present embodiment, as shown in FIG. 1, FIG. 4 and FIG. It is opened in a horizontally long rectangular shape 61a. A dustproof filter 71 is attached to the air intake port 7 to prevent dust and the like from entering the inside. In addition, the inlet 7 is not limited to what is opened by one of the side surfaces, and may be opened in the bottom plate 63.

  In addition, condensed water splashed back by the water receiving tray 3 may be applied to the dustproof filter 71 and may be accumulated on the bottom plate 63. Therefore, in the case where the intake port 7 is provided on the side surface, as shown in FIG. 4, the bottom plate 63 is a drain water for dropping condensation water on the lower side of the water receiving tray 3 on the intake port 7 side. A notch 64 is formed. As shown in FIG. 5, the bottom plate 63 in the present embodiment is bent upward at the end on the side of the intake port 7 to hold the dustproof filter 71, and the water drainage notch 64 has a height corresponding to the bending portion It is formed by cutting a portion in a substantially rectangular shape.

  The blower outlet 8 is for ventilating the wind generated by the blower fan 5 to the radiation panel 2, and is opened at the front side of the fan case 6 or at the upper part on the back side. In the present embodiment, as shown in FIG. 2, FIG. 3 and FIG. 5, the air blowing port 8 is opened on the back side to blow air from the back side of the radiation panel 2.

  Further, as will be described later, the position of the air outlet 8 deviates from the position directly below the radiation panel 2 in the direction of either the front side or the back side in order to prevent the entrance of condensed water dropped from the radiation panel 2. And the radiation panel 2 is not disposed immediately above. For this reason, the blown air does not strike the radiation panel 2 from directly below, but strikes the radiation panel 2 from a position shifted forward or backward. So, in this embodiment, the wind direction guide 81 for guiding the ventilation which blew off from the ventilation opening 8 to the said radiation panel 2 side is provided. In the present embodiment, as shown in FIG. 5, the wind direction guide 81 extends upward from the upper edge on the back side, and the tip edge thereof is inclined toward the radiation panel 2 side.

  Furthermore, as shown in FIG. 5, the top plate 62 is provided on the opposite side to the back surface where the air blowing port 8 is formed, and a structure that causes the water receiving tray 3 to drop condensation water dropped from the radiation panel 2 In order to achieve this, it is formed in a downward sloping shape with the air outlet 8 side as a base end.

  Further, in order to prevent condensation water falling from the top plate 62 from being sucked into the fan case 6 from the intake port 7 at the tip of the inclined top plate 62, the tip end side is closer to the tip than the intake port 7. It is extended, and a ridge portion 65 formed by bending the tip end edge downward is provided.

  In the panel fan 4 described above, the position at which the air blowing port 8 is shifted from directly below the radiation panel 2 to either the front side or the back side so that condensed water does not enter the fan case 6 from the air blowing port 8 It is mounted at a position where it opens upward. As shown in FIG. 2 and FIG. 3, the panel blower 4 of the present embodiment is arranged so that the air outlet 8 opens at a position shifted from directly below the radiation panel 2 to the back side. By arranging the air outlet 8 on the back side in this manner, the heat efficiency can be improved and noise can be suppressed as described later, and the projecting structure is disposed on the back side having a wall, so the front face seen by the user You can make the side design a clean impression.

  In addition, when opening the air-blowing port 8 mentioned above in the position which shifted to the front side, it becomes an arrangement configuration as shown in FIG. In this case, the wind direction guide 81 extends upward at the upper edge of the front side and is inclined toward the rear radiation panel 2 side. Further, the top plate 62 is configured to be inclined downward to the back side.

  Next, the operation of each configuration in the fan-equipped radiation type cooling and heating apparatus 1 of the present embodiment and the panel fan 4 mounted on this apparatus will be described.

  The circulating fluid cooled or heated is circulated in the radiation panel 2. The heat of the circulating fluid emits radiant heat to the surroundings through the radiation panel 2. Further, on the surface of the radiation panel 2, heat exchange is performed with the touched air to cool or heat the air.

  Further, as shown in FIG. 8 by driving the blower fan 5, the air outside the fan case 6 is taken in from the air intake port 7 and the air from which dust etc. has been removed by the dustproof filter 71 provided in the air intake port 7 is The air is blown from the air outlet 8 by the rotation of the rotary wing 51. At this time, the wind direction guide 81 guides the air blown to the upper side of the air blowing port 8 to the radiation panel 2 side. Thus, even if the air outlet 8 is disposed at a position deviated from directly below the radiation panel 2, the wind can be sent in the direction of the radiation panel 2.

  The forcedly blown air actively exchanges heat with the radiation panel 2 to increase the heat exchange efficiency. In particular, in the present embodiment, the amount of air in contact with a unit time is increased by the air blowing from the panel fan 4, and the heat exchange efficiency at the time of air conditioning and heating becomes high. When used as a cooler, the specific gravity of the air cooled by the radiation panel 2 is heavy, and a phenomenon called cold draft spreading so as to cover the floor surface tends to occur. However, the cold draft by blowing air from below Can also be suppressed.

  Furthermore, in the present embodiment, since the air blowing port 8 is disposed on the back side of the radiation panel 2, cooled or heated air is supplied to the indoor space side by blowing air from the back side to the front side. Therefore, the indoor space can be efficiently cooled and heated. Further, noise such as wind noise generated when the air is blown from the air blowing port 8 is blocked by the radiation panel 2 on the front side, so that the comfort in the room can be maintained.

  Moreover, when utilizing as a cooler, the water | moisture content contained in air will be condensed by the surface of the radiation panel 2 whose temperature is lower than the said air, and dew condensation water will generate | occur | produce. Condensed water generated on the surface of the radiation panel 2 falls downward along the heat dissipating fins 21 and the supply pipe 22 by gravity as shown in FIG.

  The panel fan 4 is disposed below the radiation panel 2 and therefore receives condensed water, but the blower opening 8 is opened at a position shifted from just below the radiation panel 2 to the back side, and therefore falls off. The dew condensation water does not flood into the fan case 6.

  In addition, the condensed water mainly falls on the top plate 62 provided on the front side opposite to the back surface where the air outlet 8 is formed, and flows downward along the downward inclination of the top plate 62, and the water receiving tray Drop into water. Therefore, the dew condensation water which fell to the top plate 62 does not flow down to the ventilation port 8 either.

  In addition, since the flange portion 65 at the tip of the top plate 62 formed in an inclined shape is provided so as to cover the intake port 7, the distance from the drop start position is maintained. Therefore, the dew condensation water falling on the water receiving tray 3 is not flooded into the fan case 6 from the suction port 7 by the suction force of the air sucked from the suction port 7.

  Further, some of the dew condensation water dropped to the water receiving tray 3 may bounce back to the water receiving tray 3 and may splash upward and be applied to the dustproof filter 71. Condensed water on the dustproof filter 71 flows to the bottom plate 63 and falls. However, since the drained water notch 64 causes the dew condensation water which has fallen to the bottom plate 63 to fall to the water receiving tray 3, the dew condensation water does not collect on the bottom plate 63. Therefore, the dew condensation water does not enter the air inlet 7 from the bottom plate 63.

  Condensed water that has fallen to the water receiving tray 3 flows down to the drainage port 31 along the inclined surface formed in a funnel shape and is drained. Thus, the dew condensation water does not wet the floor surface.

According to the fan-equipped radiation type cooling and heating apparatus 1 of the present embodiment as described above and the panel fan 4 mounted on this apparatus, the following effects can be obtained.
1. By forcing the radiation panel 2 to wind, heat exchange efficiency can be improved.
2. Since the air is blown to the radiation panel 2 from below, it is possible to suppress a cold draft that occurs when using as a cooler.
3. Since the blower opening 8 of the panel blower 4 is opened at a position shifted from immediately below the radiation panel 2, condensation water generated in the radiation panel 2 is prevented from being flooded from the blower opening 8. It is possible to prevent the failure of the 51 and the rotating motor.
4. Since the top plate 62 is formed in a downward sloping shape with the air outlet 8 side as the base end, the condensed water which has fallen to the top plate 62 does not flow to the air outlet 8 side, and the water receiving tray 3 along the inclination Can be drained.
5. Even when the air outlet 8 is disposed at a position deviated from directly below the radiation panel 2, the air flow guide 81 can blow air in the direction of the radiation panel 2.
6. The falling water notch 64 allows the dew condensation water that has bounced off the water receiving tray 3 and applied to the dustproof filter 71 to be dropped to the water receiving tray 3.
7. Since the tip of the inclined top plate 62 is formed closer to the tip than the intake port 7 in the ridge portion 65, condensation water that flows down from the top plate 62 can be prevented from being sucked from the intake port 7. .

  In addition, the fan-equipped radiation type cooling / heating apparatus according to the present invention and the panel fan installed in the apparatus are not limited to the above-described embodiment, and can be appropriately changed. For example, although the wind direction guide 81 is integrally formed with the fan case 6, the wind direction guide 81 may be formed separately and attached to the air outlet 8.
