According to this configuration, since the intermediate portion of the fixing screw is positioned in the through hole of the leg portion of the drain receiving member, it is possible to effectively prevent the occurrence of water leakage at the fixing screw.

In addition, in the implementation of the above-described 18th or 19th feature, The composition listed below can also be used.

At the lower portion of the bottom of the drain receiving member, a dew condensation water discharged from the drain port portion of the bottom portion may be continuously guided to a drain portion at a position below the contact portion of the lower support frame.

The drainage receiving member may also be formed to have a length corresponding to the horizontal width dimension of the flat heat conducting portion, and at the bottom of the drainage receiving member, the drainage water flowing from the heat conducting member is guided to the side of the water receiving tray. Common drain port.

It is also possible to fit the drain cylinder portion of the drain receiving member from above with respect to the lower portion support frame of the element, and thereby hold it.

According to a twentieth feature of the present invention, the heat transfer element formed by the longitudinal direction of the heat conductive material and the heat transfer pipe which is in contact with the heat transfer element constitute the flat heat transfer portion and support the vertical posture An element lower support frame of the lower end portion of the heat conduction element is disposed inside the lower body of the body, at least in a vicinity of an upper opening portion of the lower body of the body, and a heat insulating material is disposed inside the lower body of the body The gap-filling material is formed by the void-filling material to prevent the cold airflow cooled and lowered by the flat heat-conducting portion during the cooling operation from entering the inside of the lower casing of the body.

In other words, if the cold air from the flat heat transfer portion intrudes into the lower portion of the lower casing of the body during the air-conditioning operation, the lower casing of the body is cooled from the inner surface side due to the intrusion of the cold air. As a result, condensation may occur on the outer surface of the lower casing of the body.

On the other hand, according to the above configuration, it is possible to The generation of condensation at the outer surface of the lower casing of the body caused by the intrusion of cold air is effectively prevented.

In addition, since the void-filling material is made of a heat-insulating material, it is also possible to cause dew condensation on the outer surface of the void-filled material itself due to the low temperature due to the lowering of the cold air, or from the low temperature. The cold heat transfer from the void-filled material causes the condensation to occur at the inner and outer portions of the lower casing of the body to be effectively prevented.

According to a twenty-first aspect of the present invention, the gap-filling material is formed by joining the front side dividing portion and the rear side dividing portion, and the front side dividing portion is formed inside the gap filling material. The accommodating space that is opened by the release of the joint between the rear side dividing portions is configured to equip the inside of the lower body of the body in a state in which the gap filling material is disposed inside the lower casing of the machine body. The object is housed in the accommodating space.

According to this configuration, the internal equipment (for example, the water receiving tray or the lower support frame) of the lower casing of the living body housed in the accommodating space inside the void-filling material is a void-filled material made of a heat insulating material. The form enclosed.

Therefore, the condensation on the outside of the internal equipment in the lower casing of the body is caused by the heat and cold propagation from the internal equipment, and the inside and outside of the lower casing of the body. The occurrence of condensation can also be prevented more effectively.

Moreover, the assembly of the void filling material inside the lower casing of the machine body is set between the front side dividing portion and the rear side dividing portion to lower the body lower casing. The internal equipment is used as a bag and the segments are joined to each other.

By this, it is possible to easily assemble the void-filled material into the inside of the lower body casing in a state in which the internal equipment portion of the lower casing of the machine body is housed in the accommodating space inside the air-filled material.

Further, when inspecting or repairing the internal equipment of the lower casing of the machine body, it is only necessary to release the joint between the front side dividing portion and the rear side dividing portion and remove one of them, so that the lower casing of the body can be It is easy to inspect and repair with internal equipment.

According to a twenty-second aspect of the present invention, the front side divided portion is adhered to an inner surface of the front face panel portion of the lower body casing, and the rear side divided portion is opposed to the lower body of the body. The inner surface of the rear panel portion is sealed.

According to this configuration, the front side divided portion and the rear side divided portion in the void-filled material made of the heat insulating material can be made to the inner surface of the front panel portion and the inner surface of the rear panel portion in the lower body casing of the living body. The adiabatic effect is applied directly.

Therefore, it is possible to more reliably prevent the occurrence of condensation at the front face panel portion or the rear panel portion at the lower casing.

Further, in the implementation of the above-described 20th to 22nd feature configurations, any of the following configurations may be employed.

Alternatively, the gap-filling material may be placed in a state in which the lower portion of the element supporting frame is covered, and the void-filled material may be disposed inside the lower casing of the machine body.

It is also possible to arrange the gap filling material in a state in which the water receiving tray is covered by the gap filling material, and to arrange the gap filling material inside the lower body casing.

The filling state may be set to cover the inner surface of the lower casing of the organism and the outer surface of the water tray, and the void filling material may be disposed inside the lower casing of the body.

The front side dividing portion of the gap filling material may be installed at the inner surface of the front panel portion of the lower body casing of the body, and the inner side surface of the face panel portion behind the lower body casing of the body body is installed, and the rear side of the gap filling material is installed. Division.

According to a twenty-third aspect of the present invention, there is provided a drainage pump for draining water through a drain pipe from the water receiving tray, and a water level detecting means for detecting a water level at the water receiving tray, and when the water level is detected The detection water level obtained by the means is a drainage control means for operating the drainage pump when the drainage water level is set or higher, and the drainage control means is configured to start the drainage service in response to the detection water level being equal to or higher than the set drainage water level. After the operation of the pump, if the detected water level is lower than the set drain water level, the time for setting the drain time is started, and thereafter, the operation of the drain pump is stopped at the time point after the set drain time has elapsed.

According to this configuration, when the detection of the water level becomes the setting of the drainage water level and the operation of the drainage pump is started, when the water level of the drainage pump is operated to make the detection water level lower than the set drainage water level, the system starts to help the drainage. The timing of the drainage time is set as specified in the operation stop time of Pu.

Therefore, when there is a large amount of dew condensation water flowing from the flat heat transfer portion to the water receiving tray, the pump operation time until the water level is lower than the set drain water level and the drain time is started is set. (In other words, the pump is extended in relation to the setting of the drainage time. Time) is getting longer.

On the other hand, the operation time from the start of the operation of the drain pump to the stop of the operation is also lengthened, and the amount of displacement during the operation of the drain pump is increased.

By this, for example, when the operation of the drain pump is started when the detected water level becomes the set drain water level and the timing of the drain time is also started, it is possible to flow from the flat heat transfer portion to the drain pan. In the case where the amount of dew condensation is large, the discharge of the drainage pump and the frequency of stoppage are effectively suppressed.

Therefore, it is possible to effectively reduce the discomfort to the user's voice due to the start and stop of the drainage pump.

Moreover, it is possible to effectively prevent the drainage pump from being launched and the increase in the stop frequency in the case where the amount of inflowing water of the dew condensation water is large, and to prevent it from being infiltrated from the air cooling portion to the water receiving tray. When the leakage of the junction is less than the normal situation, the pump operation time until the detection of the water level becomes lower than the set drainage water level and the timing of the drainage time is started (the above-mentioned substantial The pump will extend the running time) and it will be shorter.

On the other hand, the operation time from the start of the operation of the drain pump to the stop of the operation is also shortened, and the amount of displacement in the one-time drain pump operation is reduced.

Thereby, when the amount of dew condensation water flowing from the flat heat transfer portion to the water receiving tray is small, it is possible to effectively prevent the water receiving tray from being stopped before the operation of the drain pump is stopped due to the excessive operation time of the drain pump. Become empty The idling of the drainage pump (that is, the operation of the pump in the absence of sufficient suction water).

Therefore, it is also possible to effectively prevent the uncomfortable sound due to the idling of the drainage pump or the early deterioration of the drainage pump.

In addition, in order to change the running time of the drainage pump in response to the change in the amount of inflow water to the dew condensation water of the water tray, it is also considered that after the operation of the drainage pump starts, the water level in the water tray is lowered to a set value. The drain water level is lower and the set timing is detected. The water level is detected at the detection time point, or the time of the drain time is set, or the water level in the water tray is lowered to the set drain water level. At the detection time point, the operation of the drainage pump is stopped.

However, in these cases, in addition to the detection of whether the water level in the water tray is above the set drain water level, it is also necessary to reduce the water level in the water tray to the set timing start water level or to set the drain. The following is detected when the water level is stopped, and the number of water levels detected is increased.

On the other hand, if the above configuration is adopted, it is only necessary to perform the detection of whether or not the water level in the water receiving tray is equal to or higher than the set drain water level, and it is also possible to detect the water level between when the water level rises and when the water level decreases. In the state in which the hysteresis is utilized, there is a difference between the water level at which the drainage pump starts to operate and the water level at which the drainage time is started.

Therefore, it is possible to reduce the number of detections of the water level, and when using a buoy switch as a water level detecting means, for example, it is possible to use only the setting. One buoy switch for drain water level can be used.

In other words, by stopping the operation of the drain pump by the timer control, it is possible to simplify the configuration of the apparatus for detecting the water level by reducing the number of detected water levels.

According to a twenty-fourth aspect of the present invention, the draining time is set to be designed such that the water level of the water receiving tray is started from the timing of the set drain time by the operation of the drain pump. The time required for the water level to rise until it is near the bottom of the water tray.

According to this configuration, even if the flow rate of the dew condensation water flowing from the flat heat transfer portion to the water receiving tray is changed, it is possible to change the operation time of the substantial pump in response to the change in the amount of the inflow water as described above. The incident complements each other, and the water stop position of the drain pump is set to the point where the drainage time is set (that is, the elapsed time of the set drain time). The water level of the water tray is lowered to the bottom of the water tray. Time point.

Therefore, it is possible to prevent the idling of the drainage pump, and it is possible to more effectively reduce the frequency of starting and stopping the drainage pump.

According to a twenty-fifth aspect of the invention, the drain control means is configured to stop the cooling operation when the detected water level has been raised to a higher limit water level than the set drain water level.

According to this configuration, even if the water level in the water tray exceeds the set drain water level and rises further for some reason, when the water level is detected to rise to the upper limit water level, the air-conditioning operation can be stopped and Further generation of dew condensation water at the flat heat transfer portion is stopped.

Therefore, it is possible to more reliably prevent the storage water of the water tray from overflowing and causing a water leakage problem.

Further, in the configuration of this configuration, it is also possible to use a detecting unit for detecting whether or not the water level in the water receiving tray is lower than the set drain water level, and detecting whether the water level in the water receiving tray has risen to the setting. The detection unit for the upper limit of the upper limit water level is configured by, for example, a separate buoy switch, and each water level is detected independently of each other.

In this case, even if the water level in the water receiving tray exceeds the set drain water level and rises due to the defect of the low-level detecting portion, it is possible to detect the water level by the high-level detecting unit. It is detected that the water level in the water tray has been raised to the upper limit water level. At this point, it is possible to more reliably prevent the water leakage problem of the storage water overflow of the water tray.

According to a twenty-seventh aspect of the present invention, in the drain control device, the detection water level is set to be higher than the setting after the cooling air operation is stopped in response to the detection of the water level being raised to the set upper limit water level. When the upper limit water level is lower, the time for setting the retention time is started, and then, at the time when the set retention time has elapsed, the operation of the drainage pump is stopped.

According to this configuration, after detecting that the water level has been raised to the upper limit water level and the cold air operation is stopped, the water level in the water receiving tray is continuously lowered to the set upper limit water level by the continuous operation of the drainage pump. , the drainage pump system is set to operate during the period of preservation, and after passing At the point in time when the holding time is set, the drain pump is stopped.

Therefore, it is possible to prevent the operation of the drainage pump required to be performed in a state where the cooling operation is stopped, and it is possible to prevent the user from being worried about the water leakage problem due to the operation of the drainage pump or more necessary. The situation.

Further, after the water level is detected to be equal to or higher than the set upper limit water level and the operation of the air cooling unit is stopped, when the water level is detected to be lower than the set upper limit water level by the continuous operation of the drainage pump, the operation of the drainage pump is started. The stop time point is used as the time limit for setting the retention time.

Therefore, similarly to the twenty-third characteristic configuration, when there is a large amount of residual dew condensation water flowing from the flat heat transfer portion to the water receiving tray after the cooling operation is stopped, the water level is determined to be a set upper limit. The pump operation time (substantial pump extended operation time) until the water level is lower and the maintenance time is set is longer.

On the other hand, when there is a small amount of residual dew condensation water flowing from the flat heat transfer portion to the water receiving tray in a state where the cold air operation is stopped, the detection water level becomes lower than the set upper limit water level. The pump operation time (substantial pump extended operation time) until the time when the maintenance time is set is shortened.

Therefore, it is possible to reliably drain the residual dew condensation water flowing from the flat heat transfer portion into the water tray while the air-conditioning operation is stopped, and it is also possible to effectively prevent the air-conditioning operation from being stopped after the air-conditioning operation is stopped. And carry out the operation of the drainage pump more than necessary.

Furthermore, if the above configuration is adopted, the configuration is the same as that of the 23rd feature. In the ground, it is only necessary to perform the detection of whether the water level in the water receiving tray is above the set upper limit water level, and also in the state in which the hysteresis of the water level detection between the water level rise and the water level decrease is utilized. There is a difference between the water level at which the air-conditioning operation is stopped and the water level at which the set-up time is set.

Therefore, it is possible to reduce the number of detections of the water level. For example, when a buoy switch is used as the water level detecting means, only one of the buoy switches for setting the upper limit water level can be used.

According to a twenty-seventh aspect of the present invention, the set retention time is designed such that the water level of the water receiving tray is started from the timing of the set retention time by the operation of the drain pump. The time required for the water level to rise until it is near the bottom of the water tray.

According to this configuration, even after the water level in the water tray has risen to the upper limit water level and the cold air operation is stopped, the residual dew condensation water remaining in the air cooling portion continuously flows into the water receiving tray, and By setting the set retention time in advance as described above, the total amount of residual dew condensation water flowing from the flat heat transfer portion after the operation stop state is included in the time after the start time of the set retention time is included. The stored water in the water tray is drained from the water receiving tray, and the drain pump is stopped in a state where the drain is almost finished.

Therefore, it is possible to prevent the idling of the drainage pump, and it is also possible to prepare for the start of the next cooling operation or the maintenance inspection until the start of the operation, and the water tray is set to be almost empty in advance. Thereby, the safety of the water leakage problem at the time of the maintenance inspection of the next cold air operation or the next cold air operation can be further improved.

Further, in the implementation of any of the features of the 23rd to 27th aspects, any of the configurations listed below may be employed.

Forming a bag-shaped pipe portion extending downward from the bottom drain port of the water receiving tray and extending upwardly therefrom, and draining the drainage pump to be installed at the drain pipe at a lower position than the bottom of the water pan In the pocket-shaped piping department.

The drainage control means is configured to stop the cold air operation when the detected water level has been raised to a higher upper limit water level than the set drain water level, and again try to start the operation of the drain pump.

The drainage control means is configured to start setting the time of the maintenance time from the point of time when the operation of the drainage pump is resumed in response to the detection of the water level rising to the set upper limit water level, and then the setting of the maintenance time is started. At the point of time after the set retention time has elapsed, the operation of the drain pump is stopped.

The set retention time is set to the total amount of residual dew condensation water that flows from the flat heat transfer portion to the water tray after the cold air operation is stopped in response to the detection of the water level rising to the set upper limit water level. The time necessary to drain from the water tray by the operation of the drainage pump.

The capacity of the water tray is designed to be able to stop cold in response to the detection of the water level rising to the above-mentioned upper limit water level. After the gas operation, the total amount of residual dew condensation water flowing from the flat heat transfer portion into the water tray is stored for storage.

The drain control means is configured to start setting the time limit for the restriction of the operation of the drain pump, and then, when the drain pump is continuously operated until the set time limit is passed, The operation of the drainage pump is forcibly stopped at the point in time when the set restriction time has elapsed.

According to a twenty-eighth aspect of the present invention, the upper frame of the body in a lateral posture in which the upper end portion of the flat heat transfer portion is coupled is provided, and the upper surface of the upper frame of the body is provided with a guide extending in the left-right direction. The groove is provided to be movable along the guiding groove so as to be movable in the left-right direction, and the sliding member capable of being fixed relative to the guiding groove by a fixing operation is to be positioned behind the lower casing of the body relative to the position The overturning prevention device that is connected to the wall is attached to the sliding member in a state in which the body member is moved in the left-right direction between the sliding members.

According to this configuration, by the movement of the sliding member in the left-right direction, it is possible to select an appropriate connection position with respect to the overturn preventing member of the wall. Further, after the appropriate joint position is selected, the slide member and the fall prevention member connected thereto are fixed by fixing operation with respect to the guide groove, and the fall prevention member is made for the wall. Linking, whereby the tipping prevention device can prevent the device from tipping over.

Therefore, it is possible to appropriately perform the process of preventing the overturning in a state in which high correspondence is provided with respect to the installation conditions of the wall structure or the like.

[First Embodiment]

Fig. 1 shows an indoor unit 1 in a natural convection type air conditioner. The indoor unit 1 is provided with a flat heat transfer portion 2 having a vertical posture exposed toward the front of the machine body. The flat heat transfer portion 2 is a rectangular shape that is vertically long when viewed in the front-rear direction.

Further, the indoor unit 1 includes a body upper frame 1A disposed in a lateral posture at the upper portion, a lower body casing 1B disposed at a lower portion, and a lower frame 1A and a lower portion of the upper body A pair of right and left body side frames 1C of the right and left sides of the casing 1B. In other words, the flat heat transfer portion 2 is surrounded by the upper body frame 1A and the lower body casing 1B and the pair of left and right body side frames 1C.

As shown in FIG. 1 and FIG. 2, the flat heat transfer portion 2 is a heat absorption and heat release of a plurality of roots (in this example, seven in this example) that span the longitudinal position of the upper body frame 1A and the lower body casing 1B. The heat conducting elements 3 are configured to be arranged side by side at equal intervals in the left and right width directions of the indoor unit 1 in a parallel posture.

That is, the flat heat transfer portion 2 is formed by a juxtaposed group of the heat transfer elements 3 in the vertical position.

At the longitudinal center shaft portion of each heat transfer element 3, as shown in Figs. 6 and 9, the straight pipe portion 4a of the heat transfer pipe 4 is made to penetrate the entire length of the heat transfer element 3.

The heat conducting element 3 and the heat conducting tube 4 are all formed by a good thermal conductive material to make. In this example, the heat conductive element 3 is made of aluminum. At the heat pipe 4, a copper pipe is used.

As shown in FIG. 7 and FIG. 9, the adjacent pairs of the upper side protrusions of the straight tube portion 4a of the heat transfer tube 4 penetrating through the respective heat transfer elements 3 are paired by the upper side tube. 4b to make a connection. Further, the adjacent pair of the lower side protrusions of the straight tube portion 4a of the heat transfer tube 4 penetrating through the heat transfer elements 3 is in an interactive relationship with the upper side and is connected to the lower side by a pair of tubes 4c to make a connection.

That is, the heat transfer pipe 4 is a meandering pipe formed by connecting a plurality of straight pipe portions 4a in series by the upper and lower pipes 4b, 4c.

One end of the meandering heat pipe 4 is connected to an outdoor unit (not shown) provided outside the room via a liquid-side passage refrigerant pipe 5a covered with a heat insulating material, and the other end of the meandering heat pipe 4 is covered by the same The gas side having the heat insulating material passes through the refrigerant pipe 5b and is connected to the same outdoor unit.

The outdoor unit installed outside the house is equipped with a compressor, an outdoor heat exchanger, an expansion valve, and a four-way valve.

In other words, in the air-conditioning operation, the outdoor heat exchanger functions as a condenser and the meandering heat pipe 4 of the indoor unit 1 functions as an evaporator to pass the two passage refrigerant tubes 5a. And 5b, the refrigerant R is circulated between the outdoor unit and the indoor unit 1.

Further, in the heating operation, the refrigerant path is switched by the four-way valve, and conversely, the outdoor heat exchanger functions as an evaporator and the meandering heat pipe 4 of the indoor unit 1 is used as a condenser. effective In the meantime, the refrigerant R is circulated between the outdoor unit and the indoor unit 1 through the two passage refrigerant tubes 5a and 5b.

In other words, in the air-conditioning operation, the heat transfer tubes 4 and the heat are adhered by the heat of vaporization caused by the evaporation of the refrigerant R inside the meandering heat pipe 4 acting as an evaporator. The heat conducting element 3 of the heat pipe 4 is cooled. By this cooling, the flat heat transfer portion 2 is subjected to heat absorption to cool the ambient air.

The air (cold air) cooled by the flat heat transfer portion 2 is naturally lowered by the flat heat transfer portion 2 in the vertical posture by the difference in specific gravity due to the temperature difference. This lowering of the cool air flows out from the lower portion of the flat heat transfer portion 2 and flows out in the forward oblique direction to the indoor unit installation room which is the air-conditioning target area.

As a result, the indoor air is cooled in the form of a large convection of the indoor air in the indoor unit installation room along with the cold air flow.

In the heating operation, the heat transfer pipe 4 and the heat pipe 4 are adhered to each other by the release of the condensation heat caused by the condensation of the refrigerant R inside the meandering heat pipe 4 acting as a condenser. The heat conducting element 3 is heated. By this heating, the flat heat transfer portion 2 is subjected to heat release to thermally radiate from the surface of the flat heat transfer portion 2 and to heat the surrounding air.

The air (heating) heated by the flat heat transfer portion 2 naturally rises along the vertical heat transfer portion 2 in the vertical position by the difference in specific gravity due to the temperature difference. This rising warm air flows out from the upper portion of the flat heat transfer portion 2 in the forward oblique direction to the indoor unit installation room.

By this, with the heating out flowing out in the indoor unit setting room The indoor air is caused to have a large convection (convection in the opposite direction to the cold air operation) to warm the room in cooperation with the heat radiation.

Further, in this example, as shown in Fig. 9, generally, one end of the meandering heat pipe 4 at the lower side of the left and right sides in the flat heat transfer portion 2 is connected to the liquid-side refrigerant pipe. 5a. Further, a gas passage side refrigerant pipe 5b is connected to the other end of the meandering heat pipe 4 at the upper portion on the left and right sides of the flat heat transfer portion 2.

As shown in FIG. 6, generally, a plurality of fins 3a and 3b extending over the entire length of the heat transfer element 3 and extending in the longitudinal direction are integrally formed on the front side and the rear side of each of the heat transfer elements 3.

Specifically, as shown in the enlarged view of Fig. 6, in general, at each of the heat transfer members 3, a columnar core portion 3c is formed and a core portion 3c is formed from the cross section thereof. The base portion 3A extending in the left-right direction formed by the substrate portion 3d extending in the left-right direction.

Then, the plurality of front side fin portions 3a are extended from the core base portion 3A (3c, 3d) toward the front side by being arranged in parallel at right and left intervals in a parallel posture.

Similarly, the same number of rear side fins 3b as the front side fins 3a are arranged side by side at equal intervals on the right and left sides in a position corresponding to the front side fins 3a. The core base portion 3A (3c, 3d) extends rearward.

At the core portion 3c, a pipe insertion hole 3e through which the heat transfer pipe 4 passes is formed. In front of the front side fin 3a extending from the core 3c The central fin portion 3a' on the side and the central fin portion 3b' on the rear side extending from the core portion 3c in the rear side fin portion 3b are formed with a component fixed at a portion before and after the connection. The fixture insertion hole 3f is used.

In other words, by providing each of the heat transfer elements 3 with a plurality of fin portions 3a and 3b having such a vertical posture, it is possible to secure a large heat transfer area and a heat radiation area of the heat transfer element 3 with respect to the surrounding air.

Further, in the air-cooling operation, the cooling air around the heat transfer element 3 is smoothly and naturally lowered by the longitudinal groove portions between the fin portions 3a and 3b, and the uncooled indoor air is smoothly induced accordingly. To the periphery of the heat conducting element 3.

Further, the dew condensation water generated on the surface of the heat transfer member 3 is conducted to the surface of the heat transfer member 3 and smoothly flows down smoothly.

Thereby, the efficiency of heat exchange between the surface of the heat-conducting element 3 and the surrounding air is kept high, whereby the cold airflow from the lower portion of the flat heat-conducting portion 2 can be efficiently and stably generated and Air convection in the room accompanying this.

Similarly, in the heating operation, the heated air around the heat transfer element 3 passes through the vertical groove portion between the fins 3a and 3b, and smoothly rises in a state accompanied by a so-called chimney effect, and is accompanied by this. The unheated indoor air is smoothly induced to the periphery of the heat conductive member 3.

Thereby, the efficiency of heat exchange between the surface of the heat conductive element 3 and the surrounding air is kept high, whereby the outflow of the heater from the upper portion of the flat heat transfer portion 2 can be efficiently and stably generated. Air convection in the room accompanying this.

As shown in FIG. 2 and FIG. 6, generally, the front surface and the left and right side surface portions of the flat heat transfer portion 2 are "C" in a cross-sectional shape viewed from a plane including the rear panel portion 6A and the left and right side panel portions 6B. The occlusion plate 6 is shaped as a occlusion.

In the occlusion plate 6, the boundary between the rear panel portion 6A and the left and right side surface portions 6B is a curved surface having a central arc shape on the inner side in plan view.

The occlusion plate 6 has a two-layer structure (an example of a stratified structure) including a good heat conductor layer 6a and a heat insulating material layer 6b.

In other words, the inner surface side of the blocking plate 6 facing the rear surface portion and the side surface portion of the flat heat transfer portion 2 (the front side portion for the rear panel portion 6A) is provided by a good thermal guide having a glossy surface. The sheet 6a (in this case, an aluminum sheet) is formed. Further, the outer surface side of the blocking plate 6 on the opposite side (the rear side of the rear panel portion 6A) is formed by the heat insulating material 6b (in this example, foamed styrene).

In other words, in the air-conditioning operation, the wall K on the back side of the indoor unit is cooled by the cooling of the heat-conductive element 3, and dew condensation occurs on the surface of the wall K. In addition, in the heating operation, the wall K on the back side of the indoor unit is heated by the heating of the heat transfer element 3, and cauterization (discoloration) occurs on the surface of the wall K.

On the other hand, the blocking plate 6 has a two-layer structure as described above, and the cold air is blocked by the blocking plate 6 and the good thermal conductive layer from the inner surface side during the cooling operation. 6a caused by the direction of the board The diffuse heat and cold conduction and the heat insulation by the heat insulating material layer 6b on the outer side can surely prevent the occurrence of condensation at the wall K.

In the heating operation, the heat-insulation by the closing plate 6 and the heat transfer of the diffusing property in the direction of the plate surface by the heat-conductive material layer 6a on the inner surface side, and the outer surface The heat insulation by the side heat insulating material layer 6b can surely prevent the occurrence of cauterization at the wall K.

In the cold air operation, the inner surface side of the blocking plate 6 is in the plate surface direction by the cold heat conduction in the direction of the plate surface direction by the good heat conductor layer 6a on the inner surface side. The temperature is uniformly lowered, whereby the air at the flat heat transfer portion 2 can be cooled, further uniformized in the left and right width directions, and further improved in efficiency. Thereby, the cold airflow from the lower portion of the flat heat transfer portion 2 can be further promoted, and the uniformity of the cold air flow in the left and right wide direction is also improved.

Further, in the cold air operation, the localized low temperature at the front side of the blocking plate 6 can be avoided by the cold heat conduction in the direction of the plate surface direction by the above-described general heat conductive material layer 6a. . Thereby, it is also possible to prevent the occurrence of dew condensation at the front side of the occlusion plate 6 due to such localized low temperature.

Similarly, in the heating operation, the inner surface side of the blocking plate 6 is in the direction of the plate surface by the warm conduction of the diffusing property toward the plate surface direction by the good heat conductor layer 6a on the inner surface side. Further, the temperature is uniformly increased, whereby the air at the flat heat transfer portion 2 can be heated and further uniformized in the left and right width directions, and further improved in efficiency. borrow Thereby, it is possible to further promote the outflow of the warm air from the upper portion of the flat heat transfer portion 2, and also improve the uniformity of the flow of the warm air in the left and right width directions.

Further, in the heating operation, the rear side and the side of the heat radiation from the surface of the heat transfer element 3 are reflected by the glossy surface on the inner surface side of the blocking plate 6, whereby the system can further The heat radiation from the flat heat transfer portion 2 to the room is promoted, and the uniformity of the heat radiation can also be improved.

As shown in FIG. 6, in general, the fin portion 3a on the front surface side of each of the heat transfer elements 3 is extended toward the front side in the left-right direction.

In other words, the virtual envelope which is viewed from the plane in which the front ends of the front surface side fins 3a are connected to each other is a curve having a pointed shape or a semicircular arc which protrudes toward the front. As a result, the outflow of the cold air during the cooling operation and the outflow of the heating and the heat radiation during the heating operation are imparted to the left and right wide directions of the indoor unit.

On the other hand, the fin portions 3b on the surface side after the respective heat transfer elements 3 are formed to be equal to each other (or even slightly equal).

In other words, the virtual envelope which is observed in a plane connecting the tips of the rear surface side fins 3b is a straight line. Thereby, in combination with the above-described general uniform diffusion of cold heat conduction or warm conduction caused by the measurement of the thermal conductive material layer 6a on the inner surface of the occlusion plate 6, it is possible to occlude the cooling or heating accompanying the heat conduction element 3 Low temperature or high temperature on the inner surface side of the plate 6 (especially on the front side of the rear panel portion 6A) It is further uniformized in the plane direction.

The heat conductive element 3 is produced by extrusion molding. By the extrusion molding, each of the fins 3a and 3b, the core portion 3c, the substrate portion 3d, the tube insertion portion 3e, and the separation preventing insertion hole 3f is formed integrally with the heat transfer element 3.

In the case of performing the extrusion molding, the surface-side fins 3d are placed in a downwardly extending posture so that the extension lengths are equal to each other. Then, the front end group of the rear side fin portions 3b is fixed and guided in the feeder, and the extrusion molding is continued.

Thereby, even if the heat transfer element 3 has a complicated cross-sectional shape, the heat transfer element 3 in the forming process can be continuously stretched and formed while being held in a stable posture. Further, it is possible to avoid formation failure of the heat conductive member 3 due to falling or the like during the forming process.

In the forming of the heat transfer element 3, the inner diameter of the tube insertion hole 3e is set to be larger than the outer diameter of the heat transfer tube 4 in advance. Thereby, after the heat transfer element 3 is formed, the pipe insertion hole 3e can pass through the straight pipe portion 4a of the heat transfer pipe 4 without any hindrance.

Thereafter, the straight pipe portion 4a of the heat transfer pipe 4 is expanded in diameter by applying a pressure such as a hydraulic pressure to the pipe of the straight pipe portion 4a of the heat transfer pipe 4. As a result, the straight tube portion 4a of the heat transfer tube 4 and the heat transfer element 3 are tightly integrated in a state where the gap remains on the inner surface side of the tube insertion hole 3e. According to this configuration, it is possible to ensure the high thermal conductivity between the heat transfer tube 4 and the heat transfer element 3.

In addition, the straight pipe portion 4a of the heat pipe is as the above-mentioned general diameter increase plus The work may be performed separately for each of the straight pipe portions 4a before the straight pipe portions 4a of the heat transfer pipes 4 are connected to each other by the pipes 4b and 4c. Further, after the straight tube portions 4a of the heat transfer tubes 4 are connected to each other by the through pipes 4b and 4c to form the meandering heat transfer tubes 4, the straight tube portions 4a may be simultaneously performed.

Further, in the above-described diameter expansion processing, the portion protruding from the end portion of the heat conduction member 3 in the straight tube portion 4a of the heat transfer tube 4 or the passage tubes 4b, 4c connected to the projection portions is borrowed. The nip is held by the mold, and the expansion of the projections or the connecting pipes 4b, 4c is prevented.

At the rear extension portion 10a of the face panel 10 before the upper body frame 1A (that is, a portion of the top plate surface at the arrangement portion where the flat heat transfer portion 2 is formed), the insertion portion of the upper end portion of each of the heat conduction members 3 is inserted. The upper portion of the through hole 10b is formed in a wave shape by being arranged side by side.

Moreover, the lower side portion 10c of the front panel 10 of the upper body frame 1A is an inclined posture in which the lower side is retracted toward the rear side. The inclined portion 10c is formed in the same manner as the rear extending portion 10a of the inclined portion 10c to form a lower surface portion of the upper frame 1A of the body.

In other words, by providing the above-described general inclined portion 10c at the lower surface portion of the upper frame 1A of the living body, the warm air flowing out from the upper portion of the flat heat transfer portion 2 during the heating operation becomes smooth and operates in the cool air. At the same time, the inflow of the indoor air toward the upper portion of the flat heat transfer portion 2 is smooth.

The lower end of the panel 7 and the lower end of the left and right side panels 8 are formed.

Similarly to the rear extension portion 10a of the front panel 10 of the upper body frame 1A, the rear extension portion 14a of the front panel 14 of the lower body casing 1B (that is, the portion of the bottom surface where the flat heat transfer portion 2 is formed) is formed. The lower notch portion 14b, which is a plurality of insertion holes through which the lower end portions of the heat transfer elements 3 are inserted, is formed in a wave shape by being arranged side by side.

On the other hand, at the rear upper panel 15, an engaging projection 15a that is engaged with the tops of the wave-shaped portions at the rear extending portion 14a is formed.

The upper portion 14c of the front panel 14 of the lower body casing 1B is an inclined posture in which the upper side is retracted toward the rear side as it goes higher. The inclined portion 14c is formed in the upper surface portion of the lower body casing 1B together with the extending portion 14a subsequent to the inclined portion 14c.

In other words, by providing the above-described general inclined portion 14c at the upper surface portion of the lower body casing 1B, the cold airflow from the lower portion of the flat heat transfer portion 2 during the cooling operation is smooth, and the heating is performed. The inflow of the indoor air toward the lower portion of the flat heat transfer portion 2 during operation becomes smooth.

That is, the above-described inclined portion 14c at the front face panel 14 of the lower body casing 1B constitutes an air flow guiding surface with respect to the lower portion of the flat heat transfer portion 2.

Inside the lower body casing 1B, a pair of front and rear lower frames 16 and a pair of front and rear element support frames 17 are disposed. Further, the front panel 14 and the rear upper panel 15, the front and rear lower frames 16, and the front and rear element lower support frames 17 are respectively coupled to the right and left side frames 9.

In the interior of the lower body casing 1B, between the front and rear lower frame 16 and the upper and lower element support frames 17 located above and above the frame 17 are disposed from the respective heat conducting elements 3 during cold air operation. The dew condensation water flowing down serves as the receiving water tray 18.

Incidentally, in the lower body casing 1B, the drainage pump 20 that discharges the dew condensation water received in the water receiving tray 18 to the outside through the drain pipe 19 is installed.

Further, a base 21 is attached to the lower surface portion of the lower body casing 1B. That is, the indoor unit 1 is installed indoors via the base 21.

Regarding the support of the heat-conducting element 3, as shown in FIG. 3, FIG. 4, FIG. 9, and FIG. 10, the lower part of the element supporting frame 17 is disposed before the lower body casing 1B of the body, by the cross-sectional shape. It is formed by a frame material which is slightly L-shaped.

The element lower support frame 17 of the previous and subsequent elements is set to be viewed from the side, and the inner portions of the L-shaped cross-sectional shapes are mutually opposite each other. The one side portion 17a is arranged in a line-symmetric posture which is slightly horizontal.

Further, the lower and lower elements of the element support frame 17. In this line symmetry posture, it is assumed that the parallel posture of the gap S1 is formed between the lines.

In the one side portion 17a of the horizontal posture of the lower frame supporting frame 17 of each element, a shallow disc-shaped resin drainage receiving member 22 extending in the left-right direction is formed so as to straddle the one side portion 17a of the front and rear portions. The state is placed in a hollow shape via a pair of leg portions 22C formed on the lower surface of the drain receiving member 22.

The drain receiving member 22 is formed by a resin (in this example, an ABS resin) which is a material having a lower thermal conductivity than a metal material constituting the lower portion of the element supporting frame 17.

Further, at a portion of the front and rear central portions of the bottom portion 22A of the drain receiving member 22, which is slightly longer than the longitudinal direction (left-right direction) of the bottom portion 22A, a dew condensation water flow from each of the heat transfer elements 3 is formed. The sprue-like drain portion 22a is controlled to the side of the water tray 18.

Further, on the lower surface of the bottom portion 22A of the drain receiving member 22, a cylindrical tubular drain portion 22D that communicates with the drain port portion 22a is formed.

Further, when the drain receiving member 22 is placed on the one side portion 17a of the horizontal posture of the element lower support frame 17 in front and rear, the drain-shaped drain tube portion 22D at the drain receiving member 22 is obtained from above. The fitting member 17 is inserted into the gap S1 between the lower support frames 17 of the element, and faces the lower drain pan 18 from directly above the water receiving tray 18.

The drain cylinder portion 22D of the drain receiving member 22 is at one side portion 17a of the horizontal posture of the lower portion of the front and rear members of the support frame 17, and is formed so as to protrude toward the side edge which is bent downward toward the side of the gap S1. Part 17e is formed at a lower position.

That is, the drain receiving member 22 is configured to receive the dew condensation water flowing from the surface of the heat conducting member 3 by the drain receiving member 22, and the dew condensation water is not made with respect to the front and rear element supporting frame 17 Contact the ground to guide to the water tray 18.

The heat transfer element 3 is supported by the lower and lower element support frames 17 via the drain receiving member 22 by placing the lower end thereof on the bottom of the resin-made drain receiving member 22. In this support, the lower side tube 4c which protrudes from the lower end of the heat absorption and discharge element 3 is from the top, and is inserted in a non-contact state to have a larger outer diameter. The wide opening of the large opening receives the slitted tubular portion 22D of the slit.

The lower end of the heat transfer element 3 is placed in the state of being placed on the drain receiving member 22, and is fixedly coupled to the front and lower element support frames 17 by the component fixing screws 23 as fixing means.

The component fixing screw 23 is inserted through the through hole 17f formed in the one side portion 17a of the element lower support frame 17 and the through hole formed in the leg portion 22C of the drain receiving member 22 from the bottom. 22h. Then, by screwing the front end side of the component fixing screw 23 to the lower end portion of the fixing tool insertion hole 3f at the heat absorbing and releasing element 3, the lower end of the heat conducting element 3 is fixedly coupled to the lower part of the front and rear support frames. 17 At the office.

That is, in a state in which the lower side through pipe 4c and the heat transfer element 3 are not directly in contact with the front and rear element support frames 17, and the support load is not applied to the lower side flow pipe 4c (especially In the state of gravity load, the heat conducting element 3 is supported by the element lower support frame 17 before and after.

Thereby, it is possible to prevent condensation from occurring on the surface of the element lower support frame 17 accompanying the cooling of the heat transfer tube 4 and the heat transfer element 3. Further, the integrated weight of the meandering heat pipe 4 and the plurality of heat conducting elements 3 is stably supported with sufficient strength without any reluctance.

The bottom portion 22A of the drain receiving member 22 is generally formed as a rounded rectangular shape in which the corner portions of the square corners are formed in an arc shape as shown in Figs. At the periphery of the bottom portion 22A, a side wall portion 22B is integrally formed.

Further, the upper surface of the bottom portion 22A of the drain receiving member 22 abuts against a plurality of strip-shaped mounting surfaces 22b extending in the front-rear direction of the lower end surface of the heat-conductive element 3, and a flow from the respective heat-conducting elements 3. The plurality of flow guiding grooves 22d which are guided to the slit-shaped drain port portion 22a in the front-rear direction are alternately arranged along the longitudinal direction of the drain receiving member 22.

The leg portion 22C of the drain receiving member 22 is generally formed as shown in Fig. 12 by an annular leg 22e and a reinforcing plate 22f and a reinforcing cylinder 2g.

The annular leg plate 22e is disposed between the outer peripheral surface of the drain cylinder portion 22D and In a state in which an annular rectangular space is formed, it is integrally formed at the bottom surface of the bottom portion 22A. Further, the reinforcing plate 22f and the reinforcing cylinder 2g are integrally formed at a plurality of places between the inner circumferential surface of the annular leg 22e and the outer circumferential surface of the drain cylinder portion 22D.

As shown in FIG. 4 and FIG. 10, in a state in which the leg portion 22C of the drain receiving member 22 abuts on one of the upper portions of the one side portion 17a of the front and rear element support frames 17, A space S4 is formed between the lower surface of the bottom portion 22A of the drain receiving member 22 other than the receiving place and the upper surface of the one side portion 17a of the element lower supporting frame 17. That is, by the existence of the space S4, it is possible to more effectively suppress the propagation of the cold heat from the heat transfer element 3 toward the lower portion of the element support frame 17.

The front and rear wide width of the drainage receiving member 22 is set to be wider than the front and rear width of the lower end surface of the heat conducting member 3 and the maximum front and rear width (the maximum front and rear width of the lower portion of the lower portion of the component supporting frame 17 before and after the mounting state). Big. Further, the length of the drain receiving member 22 in the left-right direction is set to be slightly larger than the parallel arrangement of the heat-conductive elements 3.

The width of the water receiving tray 18 is set to be wider before and after the arrangement area of the lower portion of the lower portion of the support frame 17 before and after. Further, the front end bent portion 17c of the other side portion 17b of the L-shaped cross-sectional shape of the element lower support frame 17 of the front and rear elements is positioned on the lower side of the lower support frame 17 of each element in the above-described line-symmetric arrangement. It is also set to the inclined posture of the front side and the inner side if it is the lower side.

By this, even if it is through the drain pipe 22 22D is received by the dew condensation water from the heat transfer element 3 in the water receiving tray 18, and condensation is generated on the surface of the element lower support frame 17 along with the cooling of the heat transfer tube 4 and the heat transfer element 3, and The dew condensation water on the surface of the frame is guided to the front end bent portion 17c at the other side portion 17b of the lower support frame 17 of each element and is allowed to flow down to be surely received into the inside of the water receiving tray 18.

On the other hand, as shown in FIG. 3, FIG. 5, and FIG. 9, the upper and lower element support frames 13 disposed before the upper frame 1A of the body are also the same as the lower support frame 17 of the element, by the horizontal The cross-sectional shape is formed by a frame material having a slightly L-shaped shape. The front and rear element support frames 13 are formed such that the inner portions of the L-shaped cross-sectional shapes face each other and the front end of the other side portion 13b is viewed from the side. The bent portion 13c is disposed in a line-symmetric posture that is slightly horizontal.

Further, the upper and lower elements support the frame 13. In this line symmetrical posture, it is arranged such that a parallel posture of the gap S2 is formed between the lines. The upper end of the heat-conducting element 3 is formed by the upper side through-tube 4b of the protruding heat-conducting tube from the upper end, and is inserted into the above-mentioned space S2 having a larger opening width than the outer diameter thereof from below. .

Further, the upper end of the heat transfer element 3 is opposed to the front end bent portion 13c of the other side portion 13b of the frame 13 at the upper portion of each element. Further, a ventilation gap S3 is provided between the upper end of the heat transfer element 3 and the lower surface of the front end bent portion 13c.

Further, the upper end of the heat transfer element 3 is fixedly attached to the upper and lower element support frames 13 by the element fixing pins 24 as fixing means. The component fixing pin 24 is formed at the front end bent portion 13c of the upper and lower element support frames 13, and penetrates from above.

Then, by inserting the front end side of the component fixing pin 24 into the upper end portion of the fixture insertion hole 3f at the heat absorption and discharge element 3, the upper end of the heat conduction element 3 is fixedly mounted to the upper and lower element support frame 13 .

That is, the upper end side of the heat transfer element 3 is also in a state in which the upper side flow pipe 4b and the heat absorbing and discharging element 3 are not in direct contact with respect to the element upper support frame 13, and not on the upper side flow pipe. The upper end portion of the heat transfer element 3 is supported by the upper and lower element support frames 13 in a state where the support load (especially the load having the horizontal direction component) is applied to 4b.

Thereby, it is possible to prevent the occurrence of dew condensation on the surface of the element upper support frame 13 accompanying the cooling of the heat transfer pipe 4 and the heat transfer element 3. Further, the integrated weight of the meandering heat pipe 4 and the plurality of heat absorbing elements 3 is stably supported with sufficient strength without any reluctance.

The other one side portion 13b of the L-shaped cross-sectional shape of the upper and lower element support frames 13 is positioned in the above-described line-symmetric arrangement and positioned on the lower side of the upper support frame 13 of each element, and is bent before the horizontal posture. In addition to the folded portion 13c, it is assumed that the lower side is inclined toward the front side and the rear side.

Thereby, even if condensation occurs on the surface of the element upper support frame 13 along with the cooling of the heat transfer tube 4 and the heat transfer element 3, the dew condensation water on the surface of the frame can be guided to the upper support frame 13 of each element. The other side 13b of the inclined posture is placed in the forward and backward directions as much as possible The state of the square side, that is, the state in which it is reliably received by the drain receiving member 22, flows down.

In the above-described component supporting structure, the element fixing screw 23 and the component fixing pin 24 prevent the horizontal displacement of the heat conduction element 3 and the rotation around the longitudinal axis core. Further, the heat transfer member 3 is prevented from floating upward by attaching the lower end of the heat conductive member 3 to the component lower support frame 17 with the component fixing screw 23.

Further, the upper end of the heat conductive element 3 is opposed to the front end bent portion 13c of the frame support frame 13 in the state in which the through hole S3 exists, and the upper end of the heat conductive element 3 is inserted through the fixing member. The insertion of the component fixing pin 24 of the hole 3f is fixedly mounted to the upper support frame 13 of the component, and the heat expansion and contraction of the heat conductive element 3 due to cooling and heating can be performed to cause the component fixing pin 4 and the thermal expansion and contraction. The fixture insertion hole 3f is relatively slid in the longitudinal direction to allow the thermal expansion and contraction.

By this, it is avoided that the thermal expansion and contraction (especially the thermal expansion) of the heat-conducting element 3 exerts an excessive load on each frame.

The front and rear pair of upper frames 12 are formed by a frame material having a C-shaped guide groove 12a that has a horizontal cross-sectional shape and is opened upward in the upper portion. The upper frame 12 is disposed such that the opening of the guide groove 12a is exposed to the inside of the upper surface of the upper panel 11 of the upper frame 1A of the body.

That is, when the indoor unit 1 is disposed along the rear wall K, the guide groove 12a is in a state of the wall K along the rear.

As shown in Fig. 1, Fig. 5, and Fig. 15, generally, a screw head of one screw 25 is engaged at the guide groove 12a of the rear upper frame 12. By this engagement, the screw 25 is slidably moved in the left-right direction along the guide groove 12a by the guide groove 12a as a sliding member.

Further, the screw 25 as the sliding member is prevented from being disengaged and rotated from the guide groove 12a by the engagement between the screw head and the guide groove 12a.

At the screw 25, a fall prevention tool 27 having an L-shaped cross-sectional shape is connected by a nut 26. If the nut 26 is strongly locked to the screw 25 as a fixed operation, the opening edge of the guide groove 12 is held by the screw head of the screw 25 and the nut 26, whereby the screw The 25 series is not allowed to slide. That is, by the fixing operation, the screw 25 as the sliding member and the fall prevention device 27 connected thereto are fixed with respect to the upper frame 12.

As shown in Fig. 16 (b), the overturn preventing member 27 is provided with a horizontal piece portion 27a that is a connecting portion with respect to the screw 25, and is bent at a right angle with respect to the horizontal piece portion 27a. The vertical piece portion 27b and the pair of tongue pieces 27c which are bent at right angles to the horizontal piece portion 27a at the right and left sides of the horizontal piece portion 27a to the side opposite to the vertical piece portion 27b.

Fig. 16 (a) shows a tipping prevention device 27 before the molding in which the vertical piece portion 27b and the pair of tongue pieces 27c are bent at right angles with respect to the horizontal piece portion 27a.

At the lateral piece portion 27a, it is formed to be used to insert the screw 25 before and after The long hole-shaped screw hole 27d is in the direction. By preventing the movement of the tool 27 with respect to the tilting of the screw 25 within the length of the screw hole 27, the position of the tipping prevention tool 27 with respect to the wall K is finely adjusted in the front-rear direction.

Further, three small screw holes 27e are formed in the vertical piece portion 27b. The tipping prevention tool 27 is coupled and fixed to the wall K by screwing the small screw 27f into the wall K through the small screw holes 27e.

In the sliding movement of the screw 25 and the fall prevention tool 27, the pair of tongue pieces 27c are in sliding contact with respect to the opening edge portion of the guide groove 12a. By the sliding contact, the fall prevention tool 27 is held in a posture in which the vertical piece portion 27b is opposed to the wall K (that is, an appropriate connection posture with respect to the wall K).

Further, when the nut 26 is locked with respect to the screw 25 as a fixing operation, the same is caused by the abutment of the pair of tongue pieces 27c with respect to the opening edge portion of the guide groove 12a. The rotation system of the prevention tool 27 is prevented, whereby the fall prevention tool 27 is held in an appropriate connection posture with respect to the wall K.

That is, with such a configuration, the position adjustment operation for the slide movement of the fall prevention device 27 and the fixed operation system by the nut 26 are facilitated.

In other words, when the overturn preventing member is coupled to the wall K, the tilting prevention device with respect to the wall K is selected by the movement of the screw 25 as the sliding member and the tilting prevention device 27 in the left-right direction. The appropriate link location for 27. Further, by the above fixing operation, the screw 25 is The tipping prevention member 27 is fixed relative to the upper frame 12, and the tipping prevention device 27 is coupled to the wall K by a small screw 27f. Thereby, it is possible to effectively prevent the indoor unit 1 caused by an earthquake or the like from falling over.

Further, as for the fall prevention device 27, as another embodiment, the following general configuration may be employed.

As shown in FIG. 17, generally, a pair of tongue pieces 27c which are disposed in a posture orthogonal to the wall K may be provided on the right and left sides of the horizontal piece portion 27a.

As shown in FIG. 18, in general, the horizontal piece portion 27a may be formed in a two-strand shape having two front end portions. Thereafter, screw holes 27d are provided at each of the two front end portions, and one tongue 27c along the posture of the wall K is provided between the two front end portions.

As shown in FIG. 19, the tongue piece 27c may be formed by cutting the erecting form or the like at the left and right sides of the screw hole 27d at the horizontal piece portion 27a.

On the other hand, as shown in FIG. 4, the front and rear pair of lower frames 16 are formed by a frame material having a C-shaped engaging groove portion 16a that has a horizontal cross-sectional shape and is opened downward in the lower portion. It. At the lower frame 16, the screw 28 for base connection for preventing detachment and rotation is prevented by the screw head entering the inside of the engaging groove portion 16a, and the screw 28 is opposed to the screw 28 The nut 29 is screwed and the base 21 is coupled.

The upper surface of the engaging groove portions 12a and 16a having a C-shaped cross-sectional shape is provided. The frame 12 and the lower frame 16 are formed by a common frame material. In other words, the common frame members provided with the engaging groove portions 12a and 16a are in a state in which the engaging groove portions 12a and 16a are positioned on the upper portion of the frame and in the lower portion of the frame, thereby making the postures mutually The common frame material can be used as the upper frame 12 and the lower frame 16 in a different manner.

Further, similarly, the element upper support frame 13 and the element lower support frame 17 having an L-shaped cross-sectional shape are formed by a common frame material. In other words, the common frame member having the L-shaped cross-sectional shape has a state in which the one side portions 13a and 17a are in a horizontal posture and the other side portion 13b is formed in the L-shaped cross-sectional shape. The front end bent portions 13c and 17c at the 17b position are in a horizontal posture, and the postures are used differently from each other, and the common frame member can be used as the element upper support frame 13 and the element lower support frame 17.

In other words, by using the common frame material as such, the number of necessary types of the frame material is reduced and the manufacturing cost of the indoor unit 1 is reduced.

As shown in FIG. 2, FIG. 3, and FIG. 4, in the inside of the lower body casing 1B, the box-shaped formed heat insulating material 30 which is a void-filling material is filled.

Specifically, as shown in FIG. 4, FIG. 13, and FIG. 14, generally, at the upper side of the molded heat insulating member 30, a partition portion 30c positioned at a position between the lower ends of the heat conductive member 3 is formed, and The upper side closing portion 30b is in a state of entering between the upper surface of the drain receiving member 22 and the inner surface of the lower body casing 1B.

The upper side closing portion 30b prevents the cold air from the flat heat transfer portion 2 formed by the juxtaposed group of the heat transfer elements 3 from entering the inside of the lower body casing 1B.

The lower half 30d of the accommodating portion 30a at the molded heat insulating member 30 is formed to be in close contact with the outer surface of the water receiving tray 18. That is, by the adhesion of the lower half 30d to the water receiving tray 18, the occurrence of condensation at the outer surface of the water receiving tray 18 is prevented, and the dripping of the dew condensation water when the water receiving tray 18 receives the dew condensation water is made. Become smaller.

Further, at the upper edge of the lower half 30d of the accommodating portion 30a, a recess for mounting the upper edge portion 18a of the water receiving tray 18 is formed. Article 30e.

At a lower side of the inside of the above-described shaped heat insulating material 30, a void portion 30f for arranging the drain pump 20 and the drain pipe 19 is formed. That is, by covering the drainage pump 20 and the drain pipe 19 with the molded heat insulating material 30, the sound of the sound of the drainage pump 20 is accompanied by the sound-blocking effect or the sound absorbing effect by the formed heat insulating material 30. The system is shrunk.

The through holes 30g for penetrating the left and right side portions of the lower frame 16 and the through holes 30h for penetrating the left and right side portions of the water receiving tray 18 are connected to both sides of the left and right sides of the heat insulating material 30. The accommodating portion 30a is formed.

At the lower end portion between the joint faces of the divided portions 30A and 30B on the lower side of the molded heat insulating member 30, a concave strip 30i and a pair of concave strips 30k extending in a direction extending in the left-right width direction are formed. The engaging part for assembly.

That is, by assembling the formed heat insulating material 30 inside the lower body casing 1B, the formed heat insulating material 30 is adhered to the inner surface of the lower body casing 1B and the outer surface of the water receiving tray 18, and by the The heat insulating material 30 is formed to cover the internal equipment of the lower body casing 1B. Thereby, the cold air from the flat heat transfer portion 2 is prevented from intruding into the inside of the lower body casing 1B.

With such a configuration, it is possible to prevent the occurrence of condensation on the outer surface of the face panel 14 before the lower body casing 1B due to the intrusion of cold air, and the prevention of condensation on the outer surface of the lower end portion of the back panel 7. Occurs, again, to prevent condensation from forming on the outside of the water tray 18. Raw, and the sound from the internal equipment of the lower body casing 1B is silenced.

As shown in FIG. 6, generally, in the inside of the left and right body side frame 1C, the formed heat insulating material 31 is filled in a state of being interposed between the side panel 8 and the side frame 9. The outer contour of the shaped heat insulating member 31 is formed to conform to the inner surface of the side panel 8 and the outer side surface of the side frame 9. By providing this shaped heat insulating material 31, the occurrence of condensation at the outer surface of the side panel 8 is prevented.

Further, between the good heat conductor layer 6a on the inner surface side of the side panel portion 6A on the right and left sides of the closing plate 6, and the inner side surface of the side frame 9 opposite thereto, the blocking plate 6 is interposed. The heat insulating material layer 6b on the outer side. Thereby, the heat transfer to the side frame 9 is suppressed.

Further, at the same time, as shown in Fig. 9, generally, the front end portions of the pair of front and rear element support frames 17 are interposed between the resin frame and the side frame 9 by the resin insulating spacers 32. In the state of being attached to the side frame 9. Thereby, the heat and cold conduction from the element lower support frame 17 toward the side frame 9 is suppressed, and the occurrence of condensation at the side frame 9 and the side panel 8 can be more reliably prevented. The condensation at the outside occurred.

In the molded heat insulating material 31 at the left and right body side frame 1C, a cutout portion 31a in which a pipe extending in the vertical direction is inserted is formed. In other words, the refrigerant passage 5a connected to one end of the serpentine heat transfer pipe 4 at the lower portion of the flat heat transfer portion 2 is inserted into the common portion of the pipe at the side frame 1C of the left and right sides. 31a and guided to the upper part of the body Box 1A.

In addition, the drain pipe 19 from the water receiving tray 18 is guided to the upper body frame 1A by the common cut-out 31a of the pipe at the left and right body side frame 1C.

That is, the other ends of the meandering heat pipe 4 are guided to the upper portion through the refrigerant tube 5a and the drain pipe 19, and at the upper portion of the flat heat transfer portion 2 by the pipe insertion common cut portion 31a. The three tubes that have passed through the refrigerant tube 5b are extended from the upper body frame 1A to the outside of the machine while being wound. By this, it is possible to extend the above-described three tubes 5a, 5b, and 19 to the outside by using the through holes for piping in the upper portion of the chamber wall used in the general wall-mounted air conditioner.

In addition, in the case where the through hole for piping in the lower portion of the chamber wall can be secured, the three tubes 5a, 5b, and 19 can be extended to the outside through the through hole for piping in the lower portion of the chamber wall.

As shown in FIG. 3 and FIG. 5, generally, the inner surface of the upper end portion of the back panel 7 of the face panel after the upper body frame 1A is attached is attached to the rear side of the closing plate 6 in the assembled state. The heat insulating material 6c to which the heat insulating material layer 6b is connected.

At the upper frame 1A of the body, as shown in FIG. 1 , a controller 33 is mounted therein, which performs a point of turning on or off the operation lamp or abnormal lamp disposed at the front panel 10, and The processing of the remote controller signal received by the receiving unit provided at the front panel 10, and the like.

As shown in FIG. 4 and FIG. 20, generally, at the water receiving tray 18, the drain port portion of the deep bottom portion 18a of the water receiving tray (that is, the connection of the drain pipe 19) At the mouth portion, a filter 34 for trapping dust or the like in the drain discharged to the drain pipe 19 is provided.

Further, at the water receiving tray 18, the water level detecting means for detecting the water level in the water receiving tray 18 is at the bottom of the deep bottom portion 18a of the water receiving tray 18 and the bottom portion thereof, and is separately equipped by the water receiving tray 18. The first and second buoy switches 35a and 35b that are turned ON and OFF by the change of the water level.

The controller 33 is a drain control device, and performs drainage control such that the drain pump 20 is started, stopped, or the like according to the ON and OFF operations of the buoy switches 35a and 35b.

In the above-described drainage control, specifically, (refer to FIG. 20 and FIG. 21), the first buoy switch 35a is turned on when the water level in the water receiving tray 18 is equal to or higher than the set drain water level L1. Further, the first buoy switch 35a performs an OFF operation if the water level in the drain pan 18 is lower than the set drain water level L1.

Similarly, when the water level in the drain pan 18 is equal to or higher than the set upper limit water level L2, the second buoy switch 35b performs an ON operation. Further, when the water level in the drain pan 18 is lower than the set upper limit water level L2, the second buoy switch 35b performs an OFF operation.

In order to properly discharge the stored water in the water tray 18 by the start and stop of the drain pump 20 by the ON/OFF operation of the first buoy switch 35a, the second water is not caused. The buoy switch 35b is turned ON, and the above-described upper limit water level L2 is set to be higher than the set drain water level L1.

Specifically, the controller 33 performs a control operation as described below in accordance with the ON and OFF operations of the buoy switches 35a and 35b (refer to Figs. 20 to 22).

When the water level in the water receiving tray 18 rises to the set drain water level L1 and the first buoy switch 35a is turned ON, the controller 33 starts the operation of the drain pump 20. By this, drainage from the water receiving tray 18 is started.

When the water level in the water receiving tray 18 is lowered to be lower than the set drain water level L1 and the first buoy switch 35a is turned off by the start of the drain, the controller 33 starts setting the drain time T1. Then, if the set drain time T1 has elapsed since the OFF operation time of the first buoy switch 35a, the controller 33 stops the operation of the drain pump 20. By this, the drainage from the water receiving tray 18 is stopped.

In other words, in the air-conditioning operation, the dew condensation water continuously flows into the water receiving tray 18, and the drainage pump 20 is performed by the ON and OFF operations of the first buoy switch 35a as described above. The intermittent operation is performed to maintain the water level in the water receiving tray 18 at a position lower than the upper limit water level L2 of the ON and OFF water levels of the second buoy switch 35b.

On the other hand, if the water level in the water receiving tray 18 exceeds the set drain water level L1 and rises to the set upper limit water level L2 for some reason, and the second buoy switch 35b is turned ON by this, the controller 33, is maintained by the first buoy switch 35a In the state in which the drain pump 20 is operated by the ON operation, the operation of the compressor is stopped and the circulation of the refrigerant R is stopped (that is, the cooling operation is stopped). Thereby, the generation of new dew condensation water at the flat heat insulating portion 2 is stopped.

Thereafter, if the water level in the water receiving tray 18 is lowered to be lower than the set upper limit water level L2 and the second buoy switch 35b is turned OFF by the operation of the drain pump 20 in the cooling operation stop state, the control is performed. The unit 33 starts to set the timing of the retention time T2. Then, if the set retention time T2 has elapsed since the OFF operation time of the second buoy switch 35b, the controller 33 stops the time from the water level in the water receiving tray 18 to the set drain water level L1. Drain the drainage pump 20 from the point of operation.

That is, by the operation of the drainage pump 20 covering the set retention time T2, the amount of stored water in the water receiving tray 18 is surely drained, and the drainage in the state where the cooling operation is stopped is also avoided. The necessary operation of the pump 20 is above.

Further, the controller 33 is in parallel with the start and stop operation of the drain pump 20 by the ON and OFF operations of the first and second buoy switches 35a and 35b as described above. When the operation of the Pu 20 starts, the timing of the limit time T3 is set. Then, when the operation time of the drain pump 20 is continued until the time when the set time limit T3 elapses until the time limit of the set time T3 is set, the operation is performed from the drain pump 20 as an abnormality. Forced stop of drainage at the point in time when the start time is passed and the set time limit T3 has elapsed The operation of the pump 20 is running.

Further, the set limit time T3 is set to be a time period which is more greatly increased than the set drain time T1 and the set guard time T2 described above.

As the setting retention time T2, the design of the device is set to include the drainage ground of the residual dew condensation water that continues to flow into the water receiving tray 18 after the OFF operation of the second buoy switch 35b. The drain caused by the operation of the pump 20 causes the water level in the water receiving tray 18 to be lowered from the water level at the time point when the set retention time T2 is started (that is, the OFF operating water level of the second buoy switch 35b). The time required for the drain port portion of the water receiving tray 18 (i.e., near the bottom surface of the deep bottom portion 18a of the water receiving tray).

Further, in the present example, as the set drain time T1, the device design is set such that the water level in the water receiving tray 18 is from the first buoy switch 35a by the drain due to the operation of the drain pump 20. The time required for the water level at the OFF operation time point is also lowered until the drain port portion of the water receiving tray 18 (near the bottom surface of the deep bottom portion 18a of the water receiving tray).

Further, the capacity of the water receiving tray 18 is designed to be the total amount of residual dew condensation water that can flow into the water receiving tray 18 after the compressor is stopped by the ON operation of the second buoy switch 35b. The capacity for receiving and storing the amount of water already present in the water receiving tray 18 at the time of the ON operation of the second buoy switch 35b is also included. By this, even when the cause of the poor drainage is caused by the poor condition of the drainage pump 20 itself, it is possible to surely avoid the overflow of the stored water from the water receiving tray 18. Water leakage problem.

At the drainage pump 20, a pump having a function of a check valve is used. Thereby, the backflow of the drainage from the drain pipe 19 toward the water receiving tray 18 is prevented.

Moreover, as shown in FIG. 10, the drain pipe 19 is formed with a bag-shaped pipe portion 19a extending downward from the drain port portion of the water receiving tray 18 and extending upward therefrom. Further, the drain pump 20 is placed at a position lower than the deep bottom portion 18a of the water receiving tray 18, and is interposed to the bag-like piping portion 19a (that is, the piping portion in the water-storing state).

In other words, with the help of the pump arrangement, it is complementary to the setting of the draining time T1 as described above, and the idling of the drainage pump 20 which causes the occurrence of abnormal sounds or poor pumping (such as the occurrence of abnormal sounds) That is, the pump operation in a state in which the inhaled water is not sufficiently present is prevented.

In the present embodiment, the flat heat transfer portion 2 is exposed only to the front of the indoor unit 1. However, the closed plate 6 may be omitted. The flat heat transfer portion 2 is exposed to both the front side and the rear side of the indoor unit 1. In this case, it is possible to simultaneously apply the cooling and heating due to the cold airflow or the warm air flowing out from the flat heat transfer portion 2 to the front indoor area and the rear indoor area of the indoor unit 1.

The rear panel portion 6A and the side panel portion 6B may have a multi-layer structure of three or more layers instead of the two-layer structure formed by the good heat conductor layer 6a and the heat insulating material layer 6b.

The rear surface of the flat heat transfer portion 2 may be closed by a member other than the rear panel portion 6A instead of being entirely closed by the rear panel portion 6A, or may be partially opened as a gap. Wait.

Similarly, the side surface portion of the flat heat transfer portion 2 may be partially closed by the side panel portion 6B instead of being entirely closed by the side panel portion 6B, or may be partially formed by a member other than the side panel portion 6B. Open as a void, etc.

The upper end portion of the heat transfer element 3 constituting the vertical position of the flat heat transfer portion 2 may be fixed to the state in which the thermal expansion and contraction in the vertical direction is allowed by the engagement structure or the fitting structure other than the pin. The upper part of the component supports the frame 13.

Further, the upper end portion of the heat transfer element 3 in the vertical position may be positioned at the element upper support frame 13 by an elastic member such as a coil spring or a columnar rubber material, thereby allowing the heat conductive element 3 to be Thermal expansion and contraction in the up and down direction.

Alternatively, the two ends of the component upper support frame 13 can also be inserted. It is possible to move the element upper support frame 13 up and down by the connection structure formed in the long hole or the like at the side frame 9, thereby allowing thermal expansion and contraction of the heat transfer element 3 in the up and down direction.

The respective cross-sectional shapes of the element lower support frame 17 and the element upper support frame 13 are not limited to the cross-sectional shape shown in the first embodiment, and various modifications are possible.

It is also possible to form a plurality of drain ports 22a that guide the dew condensation water flowing down from the respective heat transfer elements 3 to the water receiving tray 18, respectively.

A separate drain receiving member 22 may be disposed between the lower portion of the component support frame 17 and the respective lower ends of the plurality of thermally conductive members 3.

The respective cross-sectional shapes of the drain receiving member 22 and the water receiving tray 18 are not limited to the cross-sectional shape shown in the first embodiment, and various modifications are possible.

Further, the drain receiving member 22 is not limited to a resin, and may be a resin film formed by a suitable means such as resin coating around a metal having low thermal conductivity, ceramics, or metal.

The void-filling material that prevents the intrusion of the cold air dropped from the flat heat-conducting portion 2 may be disposed only at the upper portion of the lower body casing 1B.

Further, the void-filling material may be a sheet-like or putty-like heat insulating material.

The specific structure of the element lower support frame 17 that supports the lower end portion of the heat transfer element 3 is not limited to the structure shown in the first embodiment described above, and various modifications are possible.

The controller 33 as the drain control means may be configured such that if the water level in the water receiving tray 18 rises to the set upper limit water level L2 and the second buoy switch 35b is turned ON, the system is borrowed. The cooling operation is stopped by the stop of the compressor, and the operation of the drain pump 20 is again attempted, and the timing of the set-up time T2 is started with this attempt, and thereafter, in the timing, the second buoy switch is started. The operation of the drain pump 20 is stopped at the time point after the set operation time T2 has elapsed since the ON operation time of 35b (refer to Fig. 23).

Further, in this case, the set-up time T2 is set, and it is preferable in the device design to flow into the water tray 18 after stopping the air-conditioning operation in response to the detection of the water level rising to the set upper limit water level L2. The total amount of residual dew condensation water (including the stored water already present in the water receiving tray 18 at the time of the ON operation of the second buoy switch 35b) is drained from the water receiving tray 18 by the operation of the drainage pump 20. The necessary time.

In the water level detecting means for the water receiving tray 18, various detecting methods such as an electrode type or a pressure type can be employed.

When the water level at the water receiving tray 18 rises to the set upper limit water level L2, it is also possible to cause the controller 33 to perform an abnormality occurrence report while stopping the cooling operation.

It is also possible to have a columnar space portion between the left and right side frames 9 and the side panel 8 opposite thereto, at a position slightly higher than the water receiving tray 18, or even higher than the water tray 18. At some point, the drainage pump 20 is configured.

In this case, in the arrangement place of the drainage pump 20 in the columnar shaped heat insulating material 31 at the left side body frame 1C of the left and right sides, a defective portion for accommodating the drainage pump 20 is formed. .

In other words, when the drainage pump 20 is disposed in the space below the water receiving tray 18, it is expected that the forming heat insulating material 30 (30a, 30b) surrounding the drainage pump 20 is operated for the pump. The muffling effect of the sound. However, on the contrary, the pump operation sound system is in a state of being closed in the space portion below the water receiving tray 18, and the molded heat insulating members 30 (30a, 30b) are in a state of being vibrated with the operation of the drainage pump 20. Therefore, there is a feeling that the user is given an acoustic discomfort accompanying the operation of the drainage pump 20.

On the other hand, if the drainage pump 20 is disposed in the columnar space portion between the side frame 9 and the side panel 8 as described above, it is possible to effectively prevent such a closed operation due to the pumping sound. The resulting acoustic discomfort.

The flat heat transfer portion 2 is not limited to the case where the heat transfer elements 3 through which the heat transfer tubes 4 are passed are formed in parallel, and the heat transfer tubes 4 may be adhered to the plate-shaped heat transfer elements in the vertical position. The specific structure of the flat heat transfer portion 2 can be variously changed.

[Second Embodiment]

24 to 32 show a second embodiment of the indoor unit 1. In addition, the same function as the indoor unit 1 of the first embodiment is added with only the same symbols as those used in the first embodiment. No. Detailed description is omitted.

In the indoor unit 1 of the second embodiment shown in FIG. 24, the rear surface portion and the side surface portion of the flat heat transfer portion 2 formed by the juxtaposed group of the heat transfer elements 3 in the vertical position are closed by the closing plate 6. In the heating operation, the air inflow portion 47 that allows the air IA to flow into the arrangement portion of the flat heat transfer portion 2 from the rear side during the heating operation is provided in the air inflow portion 47, which is provided in the representative of FIG. 25, FIG. 29, and FIG. The intermediate portion of the panel portion 6A in the up-and-down direction is closed in the blocking plate 6.

In other words, in the heating operation, the air inflow portion 47 is rearward by the induction action caused by the upward flow DA of the heating generated at the flat heat transfer portion 2 accompanying the heating of the heat transfer member 3. The air IA of the space flows into the arrangement of the flat heat transfer portion 2.

When the air inflow portion 47 is formed, the panel portion 6A after the closing plate 6 is configured by the upper side plate portion 48 disposed on the upper side and the lower side plate portion 49 disposed on the lower side. In the upper side plate portion 48 and the lower side plate portion 49, the upper side plate portion 48 on the downstream side in the flow direction of the upward flow DA during the heating operation is located at the rear side of the lower side plate portion 49. .

Further, the lower side portion 48b of the upper side plate portion 48 and the upper side portion 49c of the lower side plate portion 49 are superposed on each other as viewed in the front-rear direction. In other words, a cylindrical gap formed between the lower portion 48b of the plate portion 48 and the upper portion 49c of the lower plate portion 49 at the overlapping portion is the air inflow portion 47.

In other words, this air inflow portion 47 is generally as shown in FIG. A cylindrical air guiding path 47b formed by the above-described cylindrical gap is provided. In addition, the air guiding path 47b is provided with an air outlet 47a that opens toward the upper side on the downstream side of the upward flow DA.

As shown in FIG. 30, generally, the front side portion 48c is formed at the left and right side portions of the upper side plate portion 48. Further, at the front end side of the leg portion 48c, a mounting piece portion 48d is formed. In other words, the mounting plate portion 48d is fixed to the side frame 9 by a fixing member such as a small screw, and the upper side plate portion 48 is positioned at a position further rearward than the lower side plate portion 49. The lower portion is disposed at the face after the flat heat transfer portion 2.

As is generally shown in the enlarged view of Fig. 30, between the mounting piece portion 48d of the leg portion 48c and the side frame portion 9 and the side panel portion 6B, there is an intermediary between the upper side plate portion 48 and the side frame portion 9. The heat conduction is suppressed by the heat insulation material 45.

As shown in FIG. 25 and FIG. 29, generally, the upper end side portion of the panel portion 6A after the closing plate 6 (that is, the portion on the downstream side in the flow direction of the upward flow DA from the air inflow portion 47) is An air outflow portion 43 that allows the inflow air IA from the air inflow portion 47 to flow out from the arrangement portion of the flat heat transfer portion 2 is provided. The air outflow portion 43 is provided with an opening shape that is common to the cylindrical air guiding path 47b as viewed in plan, and is opened upward.

Further, after the closing plate 6, the left and right sides of the upper half of the panel portion 6A are provided with an inducing action caused by the upward flow DA of the heating generated at the flat heat transfer portion 2 during the heating operation. The side air causes the air IA to flow into the auxiliary air inflow at the arrangement of the flat heat transfer portion 2 Part 44.

Specifically, the auxiliary air inflow portion 44 is formed by two upper and lower vertical openings 48e formed at the respective left and right leg portions 48c of the upper side plate portion 48.

As shown in Figs. 26 and 31, the lower side plate portion 49 is formed by laminating the front side heat conductive material layer 49a, the heat insulating material layer 49b, and the back surface plate 49d. In this case, the heat insulating material layer 49b is in a state of entering the concave surface portion 49e on the back side of the front heat conductive layer 49a.

Then, the lower side plate portion 49 is fixed to the side frame 9 by fixing the small and right side edges of the good heat conductor layer 49a and the back surface plate 49d, and is disposed on the face after the flat heat transfer portion 2 The lower half.

Further, as shown in the enlarged view of the enlarged view of Fig. 31, between the left and right side edges of the good heat guide layer 49a and the side frame 9 and the side panel portion 6B, the lower side plate portion 49 and the side are interposed. The heat conduction between the frame 9 is suppressed by the heat insulating material 50.

That is, as shown in Fig. 32 (a), in the heating operation, the flow in the upward flow DA of the heating generated at the flat heat transfer portion 2 is the upward flow in the middle portion in the upper and lower directions. The induction by the DA passes through the air inflow portion 47 of the rear panel portion 6A, so that the air ia in the rear space efficiently flows into the arrangement portion of the flat heat transfer portion 2.

Further, in the air inflow, in the process of passing through the cylindrical air guiding path 47b having the upward air outlet 47a which is the same as the upward flow DA, the induced air IA is rectified. Flat guide The inflow of the induced air IA in the arrangement of the hot portion 2 is more efficient and more stable.

Thereby, the inflow of the pilot air IA through the auxiliary air inflow portion 44 is complemented, and a part of the inflow air IA from the air inflow portion 47 passes through the air heated at the flat heat transfer portion 2 from the upper portion. The outflow portion 43 smoothly flows out upwardly, and the outflow of the heater from the upper portion of the flat heat transfer portion 2 is effectively promoted, and between the air at the flat heat transfer portion 2 and the heat transfer member 3 The heat exchange is also promoted, whereby the heating effect is effectively enhanced.

On the other hand, as shown in Fig. 32 (b), in the air-cooling operation, since the air outlet 47a at the air inflow portion 47 is directed upward, a part of the descending flow DA' during the cooling operation is passed. The air inflow portion 47 flows out into the rear space.

However, at this time, the efficient exchange of heat between the descending flow DA' flowing out through the air inflow portion 47 and the upper side plate portion 48 formed by the good heat guide member can effectively take the flow out toward the rear space. It reduces the heat and cold that the flow DA' holds.

Thereby, the heat insulation by the heat insulating material layer 49b provided in the lower side plate portion 49 complements the heat, and the occurrence of condensation at the rear wall K can be effectively prevented.

[Other Embodiments of Second Embodiment]

Instead of the device configuration of the second embodiment described above, it is also possible to use Any of the components listed.

Among the upper side plate portion 48 and the lower side plate portion 49, the lower side plate portion 49 in the downstream direction in the flow direction of the downflow flow DA' during the cooling operation is disposed further rearward than the upper side plate portion 48, and the upper side plate is provided. The lower portion 48b of the portion 48 and the upper portion 49c of the lower side plate portion 49 are overlapped with each other as viewed in the front-rear direction.

Further, a cylindrical gap formed between the lower portion 48b of the plate portion 48 and the upper portion 49c of the lower plate portion 49 at the overlapping portion may be an air inflow portion.

In this case, by the induction caused by the downflow DA' during the operation of the cold air, the air IA of the rear space flows into the arrangement portion of the flat heat transfer portion 2 through the air inflow portion, whereby The cold airflow from the lower portion of the flat heat transfer portion 2 toward the inside of the room during the cooling operation is promoted, and heat exchange between the heat transfer member 3 and the air at the flat heat transfer portion 2 can be promoted.

As shown in FIG. 33, it is also possible to adopt a configuration in which at least the upper and lower direction intermediate portions of the rear panel portion 6 are provided along the left and right width directions by the periphery of the axis. The guide vanes 35 (an example of the inflow direction changing means) capable of freely changing the posture can be rotated, and the inflow direction of the air IA toward the component accommodating portion 2 can be controlled by the posture changing operation of the guide vanes 35 Make changes.
