Description

  The present invention relates to an indoor unit of an air conditioner, and more particularly to a mounting structure of a display device that displays an operation status or the like for a movable appearance part.

  The indoor unit that constitutes the air conditioner occupies a mainstream type called a wall-mounted type. In this type of indoor unit, the indoor unit main body is provided with a display device that displays information such as the current time, room temperature, and outside air temperature, and a receiving unit that receives a remote operation signal. A remote controller including a display unit that is a screen to be displayed is prepared.

  When the user sets the type of air conditioning operation, set temperature, etc. while confirming the display content on the display unit of the remote controller, the signal transmitted from the remote controller is received by the receiving unit of the indoor unit body. These setting content signals are sent from the receiving unit to the control unit, and the control unit controls operating components such as a compressor and a blower.

  For example, in the indoor unit of an air conditioner disclosed in [Patent Document 1], the display device is on the lower side of the suction port formed on the front surface of the indoor unit main body and on the side portion of the air outlet provided on the lower front surface. Was provided. Since the display device is mounted in a very narrow space, it must be reduced in size, and the display content is poor only by the display of the LED lamp.

Therefore, in [Patent Document 2], an indoor unit of an air conditioner is provided, in which a large liquid crystal display device that displays an operation status is disposed slightly downward in a substantially central portion of the indoor unit body. ing. Specifically, a large liquid crystal display device is attached to the center of the front panel, and suction ports are formed on both the left and right sides.
Japanese Patent Application Laid-Open No. 11-159846 JP 2001-116333 A

  Although the technology of [Patent Document 2] improves the visibility, the central portion of the front panel facing the liquid crystal display device projects to the front side, and the aesthetics are impaired, and the manufacturability of the front panel is improved. It gets worse and costs are badly affected. In addition, a liquid crystal display device must be attached by crushing (closing) a part of the suction port formed on the front surface of the main body casing.

  The front panel that is pivotally attached to the main body casing is closed so that the center portion covers the liquid crystal display device, and suction grills are formed on both the left and right sides. That is, the opening area for suction is reduced due to the liquid crystal display device, and the amount of indoor air sucked is smaller than that of a general indoor unit, resulting in poor air conditioning performance.

  By the way, in recent years, a flat movable panel without an opening is provided to the suction port formed on the front surface of the main body, and when the operation is stopped, the suction port is completely closed to constitute a part of the appearance of the main body, and dust To prevent intrusion. At the start of operation, a structure has been adopted in which the movable panel protrudes to the front side of the main body and the indoor air is guided to the suction port through this gap.

  In this type of indoor unit, when the display device is attached to the indoor unit main body as in [Patent Document 2], when the movable panel protrudes to the front side during the air-conditioning operation, the display device is displayed from the gap between the main body and the movable panel. The information is read and lacks visibility. Moreover, it is not changed that the display device blocks a part of the gap, and the reduction of the intake amount of indoor air cannot be improved.

  The present invention has been made on the basis of the above circumstances, and the object thereof is to provide an improved visibility of a display device that displays a driving situation and the like, as well as a movable external component, and a display device. Accordingly, an indoor unit of an air conditioner capable of preventing the reduction of the amount of indoor air sucked and improving the air conditioning performance is provided.

  In order to satisfy the above object, the indoor unit of the air conditioner of the present invention has a suction port and a blower port opened in the indoor unit body, an indoor heat exchanger and an indoor blower are accommodated therein, and the movable external component is a suction port when closed. It is part of the appearance of the indoor unit body by closing and protrudes forward so that there is a gap with the suction port when opened, and the display device is attached to the movable exterior part to display information such as the operating status, and to the indoor unit body The provided display control unit is electrically connected to the display device via a lead wire to control the display device.

  The front suction port 3 provided on the front surface of the front panel 1A is opened and closed by a movable panel (movable appearance part) 6 attached via a panel opening / closing mechanism K. That is, the movable panel 6 is an external part that closes the front suction port 3 and constitutes a part of the external appearance of the indoor unit body 1 when the operation of the air conditioner is stopped or during an internal clean operation.

  As described later, when the operation of the air conditioner is started, the panel opening / closing mechanism K is activated, and the movable panel 6 is also a movable part that moves away from the front suction port 3 and projects to the front side. .

  In the indoor unit main body 1, an indoor heat exchanger 9 formed in a substantially inverted V shape by the front heat exchanger portion 9A and the rear heat exchanger portion 9B is disposed. The front heat exchanger section 9A is curved with a gap from the front panel 1A and the movable panel 6. The rear heat exchanger section 9 </ b> B is straight and inclined obliquely and faces the upper surface inlet 2.

  The electrostatic precipitator 10 is attached to the front side of the front heat exchanger section 9A. The electric dust collector 10 operates as an original dust collecting operation and an ozone generator. An air filter 11 is interposed between the indoor heat exchanger 9 and the front suction port 3 and the upper suction port 2. If the front panel 1 </ b> A is opened together with the movable panel 6, the air filter 11 can be easily inserted into and removed from the indoor unit body 1.

  An indoor blower 12 is disposed between the front and rear heat exchangers 9A and 9B of the indoor heat exchanger 9 and facing the outlet 4. The indoor blower 12 has an axial dimension substantially the same as the width dimension of the indoor heat exchanger 9, a cross-flow fan disposed facing the indoor heat exchanger 9, and a fan motor that rotationally drives the cross-flow fan. It consists of.

  The lower end portion of the front heat exchanger portion 9A is placed on the front drain pan 13a, and the lower end portion of the rear heat exchanger portion 9B is placed on the rear drain pan 13b, from the heat exchanger portions 9A and 9B on the front side and the rear side, respectively. Can receive drain water dripping and drain to the outside. The outer surfaces of the side walls of the front and rear drain pans 13a and 13b are provided at positions close to the indoor blower 12, and constitute a nose n for the fan of the indoor blower 12.

  A partition wall member 14 connects the side wall portions of the front and rear drain pans 13a and 13b constituting the nose n and each side portion of the outlet 4. A space surrounded by the partition wall member 14 is a blowout air passage 15 that communicates the nose n and the blowout port 4.

  A horizontal outlet louver 7A and a left and right outlet louver 7B are provided at the outlet 4 that opens at the end of the outlet air passage 15. Here, a plurality of left and right blowing louvers 7B connected to each other via an operating mechanism are supported on one horizontal blowing louver 7A. The horizontal and left and right blowing louvers 7A and 7B are also mechanically connected via a driving mechanism and a driving source (not shown), respectively.

  3 is a perspective view showing the appearance of the indoor unit during refrigeration cycle operation, FIG. 4 is a perspective view showing only one side of the indoor unit, and FIG. 5 is a partial perspective view of the front panel 1A and the movable panel 6 in the same state. FIG. 6 and FIG. 6 are perspective views showing only one side portion of the indoor unit in a state where the front panel 1A is fully opened with respect to the indoor unit body 1.

  The movable panel 6 has a cross-sectional shape curved along the vertical direction. In FIG. 3, the panel opening / closing mechanism K is provided only on one side (right side) of the front panel 1A in the left-right width direction and supports the movable panel 6 from the back side. Panel opening / closing mechanisms K are provided on both sides in the direction, and support both sides of the movable panel 6.

  The panel opening / closing mechanism K includes a drive shaft connected to a drive motor via a speed reduction mechanism, and a link mechanism body. The link mechanism is a parallel four-link mechanism including a fixed arm, a drive arm and a driven arm, and an auxiliary arm rotatably connected to the drive arm and the driven arm. Is provided with an auxiliary link mechanism.

When the operation switch of the remote control is switched on, the opening posture of the movable panel 6 differs depending on the selection of the operation mode.
For example, when the dehumidifying operation mode or the internal drying operation mode is selected, the panel opening / closing mechanism K causes the movable panel 6 to slightly protrude from the front panel 1A and the front suction port 3 to be in a half-open state. That is, the movable panel 6 protrudes to a position immediately before the front suction port 3, and the lower end and the upper end of each other are at substantially the same height and are in a substantially parallel state.

  When the cooling operation mode or the heating operation mode is selected, the panel opening / closing mechanism K causes the movable panel 6 to protrude as much as possible from the front panel 1A through the half-open position, and the front suction port 3 is fully opened. At this time, the lower end and the upper end of the movable panel 6 are higher than the lower end and the upper end of the front suction port 3, and the movable panel 6 is inclined with the upper end protruding forward from the lower end.

  Further, when the cooling operation mode is selected, the horizontal blowing louver 7A is inclined so as to be directed almost in the horizontal direction. When the heating operation mode is selected, the horizontal blow-out louver 7A is directed almost directly downward. In both the cooling and heating operations, the plurality of left and right blowing louvers 7B are rotationally driven while being parallel to each other.

  A display device 20 including a liquid crystal panel or an organic EL panel and an LED is attached inside one (right side) panel opening / closing mechanism K on the back surface of the movable panel 6. The display device 20 selectively displays the current time, the room temperature, and the outside temperature, displays information such as the power consumption and the electricity cost of the air conditioning operation, and can read and confirm the information via the movable panel 6. .

  From the mounting position of the display device 20 on the movable panel 6 and the operation of the panel opening / closing mechanism K, the indoor unit is wall-mounted regardless of the posture change of the movable panel 6 during the refrigeration cycle operation stop, the dehumidifying operation, and the cooling / heating operation. Although it is called a shape and is attached to the height of the wall surface, the resident can ensure good visibility with respect to the display device 20 in both the sitting posture and the standing posture.

  On the other hand, one side portion of the indoor heat exchanger 9 is disposed with a gap from the side plate of the indoor unit main body 1, and an electrical component box 16 that houses the control unit is disposed in the gap. The control unit is electrically connected to a receiving unit that receives a signal from the remote controller, a front suction port 3, a top suction port 2, an indoor heat exchanger 9, a blower port 4 and the like, and is electrically connected to a transmission unit. Receive the incoming signal.

  And a control part is a drive source of the louver opening and closing mechanism which drives the electrode which comprises the electrostatic precipitator 10, the drive motor of the indoor air blower 12, the horizontal blowing louver 7A and the right-and-left blowing louver 7B provided in the blower outlet 4, and an outdoor unit and electricity Are connected to each other and send necessary control signals to the respective components.

  Further, the control unit includes a display control unit S that controls the display device 20, and the display control unit S and the display device 20 are electrically connected via a lead wire R as described later. The lead wire R is accommodated in a lead wire protection structural component H to be described later over the entire length, and even if the movable panel 6 protrudes to the maximum extent, the lead wire R is in the lead wire protection structural component H and is not exposed.

Next, the lead wire protection structural component H will be described.
7 is a perspective view of the assembled display device 20 and the lead wire protection structure component H, FIG. 8 is an exploded perspective view of the display device 20 and the lead wire protection structure component H, and FIGS. FIG. 10 is a plan view of the assembled display device 20 and lead wire protection structural component H. FIG.

  The lead wire protection structural component H includes a lower case 22 connected to the display device 20 via a first bent portion 21, and an upper case 23 that forms an internal space with the lower case 22 and is slidably fitted. And a lead wire guide 24 accommodated in the lower case 22 and the upper case 23.

  Furthermore, the lead wire protection structural component H is connected to the upper case 23 via the second bent portion 25, and is connected and fixed integrally with the guide member 26, and is rotatable to the front panel 1A. It is comprised from the hinge member 27 supported by.

  In other words, in the lower case 22, the upper surface and the side surfaces of the display device 20 side and the counter-display device 20 side are opened, and the lower surface portion and both side surface portions are integrally bent. A hinge portion 21 a is provided at one end portion, and is fitted to a hinge receiving portion 21 b provided in the display device 20. The hinge portion 21a and the hinge receiving portion 21b constitute a rotation shaft, which becomes the first bent portion 21.

Further, the lower surface portion of the lower case 22 is provided with a rectangular protrusion 30 in plan view, which is for guiding the lead wire R. A long hole 31 is provided in the vicinity of the bottom surface of the lower case 22 where the protrusion 30 is provided.
For convenience of explanation, a line direction connecting the display device 20 side and the counter display device 20 side is referred to as a “Y direction”, and a direction orthogonal to the Y direction is referred to as an “X direction”. The long hole 31 provided in the lower surface portion of the lower case 22 is formed long in the X direction.

  As shown in FIGS. 9A and 9B, a circular protrusion 32 provided on the lead wire guide 24 is fitted into the elongated hole 31 provided in the lower case 22. The lead wire guide 24 is a top member having an oval shape in plan view and a predetermined height. A perfectly circular shaft portion is provided on the surface portion opposite to the surface portion on which the protrusion 32 is provided, and a positioning protrusion 33 is provided at the tip of the shaft portion as shown in FIG.

  The positioning protrusion 33 has a circular shape and is integrally provided with a rectangular protrusion at an opposing portion. A cut portion 35 is provided from a surface portion where the protrusion 32 of the lead wire guide 24 is provided to a surface portion where the positioning projection 33 is provided, and the surface portion where the protrusion 32 is provided is divided into two.

  The upper case 23 has two surfaces that face the lower surface in the Y direction and are bent at both side surfaces that face the upper surface in the X direction. On the upper surface portion of the upper case 23, a hooking hole 36 for hooking the positioning protrusion 33 of the lead wire guide 24 is provided. The length dimension of the shaft portion that is the base end of the positioning projection 33 is slightly larger than the thickness of the upper surface portion of the upper case 23.

  The hooking hole 36 has a similar shape to the positioning protrusion 33, and if the lead wire guide 24 is rotated after the positioning protrusion 33 of the lead wire guide 24 is inserted into the hooking hole 36 of the upper case 23. The position of the positioning projection 33 with respect to the engagement hole 36 is shifted, and the lead wire guide 24 cannot be extracted from the upper case 23.

  A fan-shaped protrusion 37 is provided on the upper surface of the upper case 23 at a predetermined angle with the hooking hole 36 as a center, and restricts the rotation range of the lead wire guide 24 attached to the upper case 23. On the other hand, the lead wire guide 24 can be accommodated in the internal space between the upper case 23 and the lower case 22 by fitting the lower case 22 to the open surface portion of the upper case 23.

  The upper case 23 and the lower case 22 are slidable along the Y direction, which is the length direction, and the lead wire guide 24 rotates in the fan-shaped protrusion 37 of the upper case 23 as the slide occurs. At the same time, the protrusion 32 of the lead wire guide 24 moves in the long hole 31 of the lower case 22, and the amount of rotation of the lead wire guide 24 relative to the sliding amount of the upper and lower cases 23, 22 is restricted.

  As shown in FIG. 8 again, a hinge portion 25 a is provided at one end portion in the Y direction on the upper surface portion of the upper case 23, and is fitted to a hinge receiving portion 25 b provided on the guide member 26. The hinge portion 25 a of the upper case 23 and the hinge receiving portion 25 b of the guide member 26 constitute a rotation shaft, which is the second bent portion 25.

An internal space through which the lead wire R is inserted is secured in the guide member 26 and the hinge member 27 connected to the guide member 26.
As shown in FIG. 10, one end of the lead wire R indicated by a two-dot chain line is connected to the display device 20. Further, the lead wire R is inserted through a first bent portion 21 composed of the display device 20 and the lower case 22, and is guided to an internal space where the lower case 22 and the upper case 23 are combined. The 24 cut portions 35 are inserted through.

  The lead wire R exiting the cut portion 35 is guided between the end portion of the lead wire guide 24 and the side portions of the upper and lower cases 23 and 22. Therefore, the lead wire R is bent in a crank shape in the internal space where the lower case 22 and the upper case 23 are combined. Even if the lead wire guide 24 is rotationally displaced with the positioning projection 33 as a fulcrum, the shape of the lead wire R does not change.

  The lead wire R is inserted into a second bent portion 25 composed of the upper case 23 and the guide member 26, led from the guide member 26 to the hinge member 27, and is bent here. The lead wire R protrudes from the hinge member 27 and is connected to the display control unit S accommodated in the electrical component box 16.

  In the indoor unit of the air conditioner described above, for example, when the dehumidifying operation mode is selected, the refrigeration cycle operation is started, and the panel opening / closing mechanism K acts to cause the movable panel 6 to protrude forward from the front panel 1A. . The protruding amount at this time is small, and a slight gap is formed between the movable panel 6 and the front panel 1A.

  The indoor blower 12 performs a blowing action in a state where the air volume is extremely small, and the horizontal blowing louver 7A rotates so that the upper end thereof has a slight gap from the upper end of the blowing port 4. The heat exchange air, which has been led to the indoor heat exchanger 9 and has evaporated water, is led along the back surface side of the movable panel 6 from the blowout port 4, and indoors through the front suction port 3 and the gap between the movable panel 6 and the front panel 1 </ b> A. It is sucked into the machine body 1.

Then, heat is exchanged with the indoor heat exchanger 9 again, and almost no heat exchange air is blown into the room from the blowout port 4, and the front and back surfaces of the movable panel 6, which is the front surface of the indoor unit body 1, and the indoor heat exchanger 9. In a short circuit condition. A dehumidifying action is performed in a state where cold air does not hit the occupants in the room, and comfortable air conditioning is obtained.
Alternatively, drain water droplets adhering to the indoor heat exchanger 9, the front and rear drain pans 13a, 13b, the ventilation path 15 and the like are quickly evaporated to dry the interior of the indoor unit main body 1, thereby preventing the occurrence of mold. In any case, the air intake performance is improved by securing the suction area.

  When the cooling operation mode or the heating operation mode is selected, the panel opening / closing mechanism K fully opens the movable panel 6 with respect to the front suction port 3. The horizontal blowout louver 7A is directed almost horizontally during cooling operation, so that cold air is not directly applied to the resident. During the heating operation, it is directed almost downwards and blows warm air to the feet of the residents.

  In both the cooling and heating operations, the panel opening / closing mechanism K causes the movable panel 6 to protrude forward (front side) as much as possible. Therefore, the movable panel 6 moves upward from the position where the front suction port 3 shown in FIG. 1 is completely closed and the half-open position, and tilts obliquely.

  During cooling operation and heating operation, a large amount of room air enters the indoor unit body 1 through the front suction port 3 from the gap between the movable panel 6 and the front panel 1A, and enters the indoor unit body 1 from the upper surface suction port 2. The air is sucked and led to the indoor heat exchanger 9. A sufficient air volume can be ensured in any operation, the residence area in the indoor heat exchanger 9 is reduced, and the heat exchange efficiency and the air conditioning performance are improved.

By attaching the display device 20 to the movable panel 6, there is no resistance against room air sucked from the front suction port 3. Therefore, it is possible to prevent the reduction of indoor air intake and improve air conditioning performance.
As the movable panel 6 moves, the display device 20 moves to a position above the outlet 4 so that it is not directly affected by the cold air during the cooling operation and no condensation occurs. During heating operation, it is not affected by the direct heat effect of warm air, and no thermal deformation occurs.

  When the operation switch of the remote control is turned off, the refrigeration cycle operation is terminated and the actions of the indoor blower 12 and the electric dust collector 10 are stopped. The panel opening / closing mechanism K moves the movable panel 6 backward to bring it into close contact with the front panel 1A. Since the front suction port 3 is closed, dust does not enter the interior of the indoor unit body 1 from here. The air outlet 4 is closed by a horizontal air outlet louver 7A, and dust is prevented from entering the interior of the indoor unit body 1.

  As described above, when the refrigeration cycle operation is stopped, the movable panel 6 closes the front suction port 3 and when the dehumidifying operation mode is selected, the panel opening / closing mechanism K opens the movable panel 6 halfway with respect to the front suction port 3. To open. When the cooling operation mode or the heating operation mode is selected, the panel opening / closing mechanism K opens the movable panel 6 to the front suction port 3 fully open.

  The movable panel 6 protrudes from the closed position of the front suction port 3 to the front side of the front panel 1A, and the protruding postures differ from each other depending on the operation mode. As the movable panel 6 moves as described above, the display device 20 changes its posture, and the lead wire protection structural component H must follow the operation.

  That is, when the refrigeration cycle operation is stopped, the display device 20 is in a substantially vertical posture as shown in FIG. When the dehumidifying operation mode is selected, the movable panel 6 slightly protrudes from the front panel 1A, and the bent form of the lead wire protection structural component H slightly changes accordingly.

  The first bent portion 21 that connects the display device 20 and the lower case 22 rotates, and the second bent portion 25 that connects the upper case 23 and the guide member 26 rotates. At the same time, the distance between the axes of the first bent portion 21 and the second bent portion 25 changes to some extent, but the lower case 22 and the upper case 23 are configured to be slidable in the length direction (Y direction). The protective structural component H does not have any trouble in the operation of the movable panel 6 and smoothly expands and contracts.

  When the cooling operation or the heating operation is selected, as shown in FIG. 5, the movable panel 6 protrudes obliquely upward with respect to the front panel 1 </ b> A and the posture changes greatly. Accordingly, the first bent portion 21 that connects the display device 20 and the lower case 22 rotates greatly, and the second bent portion 25 that connects the upper case 23 and the guide member 26 rotates significantly.

  At the same time, the distance between the axes of the first bent portion 21 and the second bent portion 25 changes greatly. Also here, since the lower case 22 and the upper case 23 are configured to be slidable in the length direction (Y direction), the lead wire protection structural component H follows the operation of the movable panel 6 smoothly without any trouble. Stretch and change.

In other words, the panel opening / closing mechanism K is composed of a combination of a parallel link mechanism and an auxiliary link mechanism, and is completely different from the simple operation of rotating the movable panel 6 around the upper end as a pivot point. Open and close in the state.
The display device 20 is attached to the movable panel 6, and the lead wire R connecting the display device 20 and the display control unit S is housed and protected by a lead wire protection structural component H. Naturally, the lead wire protection structural component H needs to operate in accordance with the operation of the panel opening / closing mechanism K.

  However, the drive center position of the lead wire protection structural component H is configured to be inconsistent with the drive center position of the panel opening / closing mechanism K. If no measures are taken in the lead wire protection structural component H, the driving resistance of the panel opening / closing mechanism K will be generated, and the smooth operation of the movable panel 6 will be hindered.

  Therefore, the lead wire protection structural component H according to the present invention includes a first bent portion 21 and a second bent portion 25 that are bent in accordance with the movement of the movable panel 6. The first and second bent portions 21 and 25 are fitted with the hinge portions 21a and 25a and the hinge receiving portions 21b and 25b to constitute a rotation shaft.

  The lead wire protection structural component H includes two rotating shafts that are spaced apart from each other in parallel. In addition, the lower case 22 and the upper case 23 interposed between the first bent portion 21 and the second bent portion 25 constituting the pivot shaft are combined in a slidable manner in the Y direction which is the length direction. The distance between the pivot shafts is variable.

  As described above, the drive center position of the lead wire protection structure component H does not match the drive center position of the panel opening / closing mechanism K. However, the lead wire protection structure component H does not obstruct the operation of the panel opening / closing mechanism K. It operates and does not become a driving resistance of the movable panel 6.

  Furthermore, the lead wire protection structural component H includes a lead wire guide 24 that adjusts the length of the lead wire R in accordance with the change in the distance between the rotation axes. Specifically, the positioning protrusion 33 of the lead wire guide 24 is rotatably attached to the upper case 23, and the protrusion 32 of the lead wire guide 24 is slidably fitted in the long hole 31 of the lower case 22. Yes.

  The long hole 31 is long in the X direction perpendicular to the length direction (Y direction) of the lead wire protection structural component H. With such a configuration, the angle of the lead wire guide 24 changes in a state where it is regulated by the long hole 31 according to the expansion and contraction along the Y direction of the lead wire protection structural component H, and the crank shape is formed along the lead wire guide 24. The length of the lead wire R to be bent is adjusted.

  As a result, even if the bending posture of the lead wire protection structural component H changes according to the change in the posture of the movable panel 6, the lead wire R is not pulled or loosened inside, and a certain degree of tension is maintained. In this state, the length is adjusted. The bending stress applied to the first and second bent portions 21 and 25 is reduced, and deformation and breakage are prevented.

Since the lead wire R is bent into a crank shape and the lead wire guide 24 for adjusting the length is provided, the lead wire R can be kept from being tensioned when the lead wire protection structural component H is extended. The lead wire R is prevented from being sandwiched between components of the lead wire protection structural component H.
As the posture of the movable panel 6 changes, the lead wire R that electrically connects the display device 20 and the display control unit S also changes in shape, but the lead wire R is not caught by other components. The lead wire protection structural component H that protects the lead wire R does not come into contact with other components.

Furthermore, according to the present invention, the display device 20 is provided on the movable panel 6 which is an external component of the air conditioner indoor unit, and information such as electricity bills is displayed with numbers, etc. The user can display the necessary information.
Since the display device 20 is fixed so as to be integrated with the movable panel 6 and is connected to the display control unit S provided in the indoor unit body 1 by the lead wire R, the distance of the display device 20 from the external surface is increased. The display looks constant regardless of where it is operated.

Since the display device 20 is located immediately before the electrical component box 16 (display control unit S) provided in the indoor unit body 1 when the refrigeration cycle operation is stopped, the length of the lead wire R is the shortest. Since the lead wire protection structural component H covers almost the entire area of the lead wire R, the lead wire R is protected from breakage and breakage accidents at the entire length and the connection end portion, thereby obtaining reliability.
The present invention is not limited to the above-described embodiments as they are, and can be embodied by modifying the components without departing from the scope of the invention in the implementation stage.
