Description

  The present invention relates to an air conditioner capable of suppressing deformation and breakage of piping due to an impact applied during transportation or installation.

  In the current air conditioner, a compressor and a four-way valve are installed in a narrow space in order to save the space of the casing, and a large number of pipes are arranged therebetween. Since piping is easy to move, when an external force is applied to the housing, the positional relationship of the piping may be deformed, or the piping may be deformed or damaged due to contact with each other.

  Conventionally, as shown in FIG. 20, a fixture 71 in which a holding portion 72 that holds a pipe is formed at both ends is formed, as shown in FIG. It was mounted between two of the pipes connected to the four-way valve 74, and the periphery was fastened and fixed with a binding band 73. And as shown in the figure, three pipes were fixed by using three fixing tools 71.

  If only two fixtures are used for three pipes, as shown in FIG. 22, the pipes are still in a rotatable state, and there is a possibility that the pipes come into contact with each other. Therefore, in order to securely fix the pipes, three fixing tools are required for the three pipes, and there are problems in cost and workability.

  In order to solve this problem, Patent Document 1 discloses a fixing device of a type that is fixed to a housing (see FIG. 2) and a fixing device that fixes three pipes (see FIG. 3).

JP 2006-125699 A

  However, in the fixing tool described in FIG. 2 of Patent Document 1, it takes time and labor to attach the fixing tool to the housing. Moreover, in the fixing tool described in FIG. 3 of Patent Document 1, three pipes can be fixed with one fixing tool. However, the fixing tool is attached to the three pipes with the fixing tool attached thereto. There was a problem in workability because it was necessary to hang a string-like fixed part around the periphery, that is, around the three pipes.

  Then, in view of the above, an object of the present invention is to provide an air conditioner including a pipe fixing tool that is easy to mount and can effectively suppress deformation and breakage of the pipe.

In order to solve the above problems, a packing device according to an aspect of the present invention is a packing device for packing an outdoor unit of an air conditioner, and includes a bottom tray on which the outdoor unit is placed, and the bottom tray. A cushioning material interposed between the outdoor unit, the bottom tray opening upward and having a bottom surface and a side surface, and the cushioning material is opposed to the inside of the side surface of the bottom tray. It has a chamfered portion at the corner on the upper end side of the outer peripheral portion.

As described above, the air conditioner of the present invention, as a fixture for fixing a pipe connected to a four-way valve, has an end portion on one side of a pair of L-shaped members arranged with one side back to back, and a hinge portion. The main body connected via the central pipe holding part formed near the hinge part, the end pipe holding part formed at the end of the other side of each L-shaped member, and the L-shaped members.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 and 2 are refrigerant circuit diagrams showing an embodiment of an air conditioner according to the present invention. As shown in the figure, the air conditioner of the present embodiment is a separate single air conditioner in which one indoor unit 2 is connected to one outdoor unit 1, and a compressor accommodated in the outdoor unit 1. 3, the three-way valve 9, the outdoor heat exchanger 4 and the expansion device 5 are connected in series in this order with refrigerant pipes, and the indoor heat exchanger accommodated in the indoor unit 2 from the expansion device 5 through the two-way valve 6 7 is connected to the pipe, and the refrigerant circuit is configured by connecting the pipe from the indoor heat exchanger 7 through the three-way valve 8 to the outdoor compressor 3 through the four-way valve 9 again.

  Since the compressor 3 is connected to the refrigerant circuit via the four-way valve 9 that is a switching valve, by switching the four-way valve 9, either the outdoor heat exchanger 4 side or the indoor heat exchanger 7 side is selected. The compressed refrigerant can also be sent out in the direction. By switching the four-way valve 9, the outdoor heat exchanger 4 and the indoor heat exchanger 7 are used as a condenser or an evaporator.

Specifically, in FIG. 1, the high-temperature refrigerant discharged from the discharge pipe 11 of the compressor 3 passes through the heat exchanger side pipe 12 via the four-way valve 9 and flows in the direction of the arrow shown in the figure. It flows into the indoor heat exchanger 7 as an evaporator through the outdoor heat exchanger 4 and the expansion device 5. The refrigerant sent from the indoor heat exchanger sequentially passes through the three-way valve side pipe 13, the four-way valve 9 and the suction side pipe 14 and returns to the compressor 3, whereby the cooling operation is executed.

  In FIG. 2, the refrigerant discharged from the discharge pipe 11 of the compressor 3 passes through the three-way valve side pipe 13 by switching the flow path of the four-way valve 9, flows in the direction of the arrow shown in the figure, and indoor heat as a condenser It flows into the outdoor heat exchanger 4 as an evaporator through the exchanger 7 and the expansion device 5. The refrigerant sent out from the outdoor heat exchanger 4 sequentially passes through the heat exchanger side pipe 12, the four-way valve 9 and the heat exchanger side pipe 12 and returns to the compressor 3, whereby the heating operation is performed.

  The indoor unit 2 accommodates an indoor fan 15 (for example, a cross flow fan). When the indoor fan 15 is operated, indoor air is taken into the indoor unit 2 and heat is exchanged by the indoor heat exchanger 7. . Then, as shown in FIG. 3, conditioned air is blown out from the air outlet 16 of the indoor unit 2. A louver 17 is disposed at the air outlet 16 and sends out conditioned air in a desired direction.

  FIG. 4 is a control block diagram of a remote control device (remote control) for remotely controlling the air conditioner according to the present invention. The remote controller 21 uses a battery as a power source. When the battery runs out, the remote controller 21 is reset, and the time information (including date) disappears and returns to the factory setting time (default setting time). There was the inconvenience that it took time. In addition to the battery running out of the remote control, when the reset key is provided on the remote control unit, the resetting method includes pressing the reset key to make it the same state as when replacing the battery. .

  As a method to solve the above problem, when replacing the battery, the air conditioner main body side is stored by a method of storing the electric charge in the capacitor and not turning off the power of the microcomputer that counts the time, or by direction communication along after the battery replacement The method of receiving time information from was known.

  However, in the method of storing electric charge in the capacitor, since the capacity is small, there is a possibility that the potential drops while replacing the battery. Further, in the method of receiving time information from the air conditioner body side by bidirectional communication, a bidirectional communication mechanism is required between the remote controller and the air conditioner body, leading to an increase in cost.

  Therefore, in the present invention, when the non-volatile memory is mounted on the remote control 21 and the remote control is reset by updating the date information every day (when the battery runs out or when a reset key is provided) Even when the battery is replaced or when the reset key is pressed and the reset is performed, the date information when the battery runs out or when the reset key is pressed The date information was displayed. Thereby, it is possible to shorten the time required for the user to set the time again.

  Specifically, the air conditioner of the present invention includes a remote controller 21 that remotely controls the refrigeration cycle of the refrigerant circuit. The remote controller 21 inputs a display unit 22 that displays the date and time, and the date and time. And a terminal control unit 24 for starting time measurement based on date information and time information input by the user and storing the input date information in a nonvolatile memory. Then, the terminal control unit 24 determines whether date information is stored in the non-volatile memory when a battery is inserted in the remote controller 21 or when a reset key is pressed. Is stored in the display unit 22, and when it is determined that the date / time information is not stored in the nonvolatile memory, the default setting is displayed. Show time Thereafter, when the date and time are set by the operation of the operation unit 23 of the user, the date information is stored in the nonvolatile memory, and the year stored in the nonvolatile memory every day after that date. Update the date information.

  The contents of the control performed by the terminal control unit 24 will be described in detail with reference to FIG. In the present embodiment, the remote controller 21 is provided with a reset key, and as a method for setting the remote controller 21 to the reset state, either battery replacement or pressing the reset key can be selected. . The remote controller 21 may or may not be provided with a reset key. In FIG. 5, a case where a battery is inserted in the remote control will be described as a method for setting the remote control device to the reset state. The terminal control unit 24 has a CPU, a ROM, a RAM, and a nonvolatile memory. When a battery is inserted into the remote control 21, whether or not date information is stored in the nonvolatile memory, that is, in a default state. Judge whether there is.

  If the terminal control unit 24 determines that the date information is stored in the non-volatile memory (not the default state), the terminal control unit 24 reads the stored date information and the specific set time and displays them on the display unit 22. To do. In the present embodiment, “0:00” is displayed as the specific time. In addition, “13:00” may be displayed as the specific time. The time of 13:00 is a time approximately in the middle of the person's activity time zone, and when inputting the actual time, the time can be set in a short time. On the other hand, if the terminal control unit 24 determines that the year / month / day information is not stored in the nonvolatile memory (the default state), the terminal control unit 24 displays the default setting time on the display unit 22.

  In order to adjust the time displayed on the display unit 22 to an accurate time, the operation unit 23 is provided with a “date and time setting button”, “decision button”, “forward button”, and “return button”. In order to set the time, first, the “date and time setting button” is pressed, and thereby the “year” display blinks. When the “OK” button is pressed in this state, the “year” display is confirmed, and then the “month” display flashes. In this way, by pressing the “OK” button, the blinking locations of “year”, “month”, “day”, “hour”, and “minute” move in order.

  When the terminal control unit 24 determines that it is not in the default state, the “year”, “month”, “day” display on the display unit 22 is “year”, “month”, “day” stored in the nonvolatile memory. Is displayed. Therefore, if the “year”, “month”, and “day” stored in the non-volatile memory are correct values (current “year”, “month”, and “day”), press the “OK” button. Just go and the “year”, “month”, and “day” indications are finalized. Since “0” is displayed in the “hour” display, the “advance button” or “return button” is used to adjust the actual “hour” and press the “decision button”. Then, since “00” is displayed in the “minute” display, the “advance button” or “return button” is used to match the current “minute” and the “decision button” is pressed. As a result, the time including the date is confirmed, and the time setting operation ends.

  If the battery is replaced when the battery runs out after the month and day have passed, the “year”, “month”, and “day” stored in the non-volatile memory are advanced as described above. By operating the “button” or “return button”, the current “year”, “month”, and “day” can be set. In addition, the present here is not a strict present, but the user can listen to the time information of the telephone or display the time displayed on the TV screen, wall clock, wristwatch, remote control with another clock function, etc. A situation is assumed that means setting the year / month / day / hour / minute of the remote control while looking at the date / month / date / time information other than the remote control for which the month / day information is to be set. For this reason, there is a case in which the current year, month, date and time are not exactly the same.

  The terminal control unit 24 stores the set date information in the non-volatile memory, and starts measuring time from the set time. Thereafter, the terminal control unit 24 determines whether the date has changed, and updates the date information stored in the nonvolatile memory when it is determined that the date has changed.

  When the terminal control unit 24 determines that it is in the default state, the factory setting time (default setting time) is displayed on the display unit 22. The “year”, “month”, and “day” indications at this time are usually not accurate values because the year and month have passed since the factory shipment. Therefore, the time setting is completed by pressing the “OK” button after setting the date to the correct value (current date) with the “Proceed” button or “Return button” and then setting the time to the correct display. To do. The subsequent steps are the same as when the default state is determined.

  Here, a specific example will be described. It is assumed that the default setting time at the time of factory shipment is “January 1, 2013 0:00”. When the user sets the time for the first time on “January 8, 2014, 14:00”, “January 1, 2013, 0:00” is displayed on the display unit of the remote controller. The user uses “Proceed button” and “Return button” to set “Year” to “2014” and press “OK” button to confirm “2014”.

  Next, since “January” is displayed for “Month”, the “OK” button is pressed to confirm “January”. Subsequently, “8 days” is confirmed by pressing “OK” button in accordance with “8 days” using “forward button” and “return button” for “day”. Next, “14” is confirmed by pressing the “OK” button in accordance with “14” using the “advance button” and “return button” for “time”. Next, since “00” is displayed for “day”, the “enter button” is pressed to confirm “00”. In this way, “January 8, 2014 14:00” is set.

  After that, it is assumed that the battery runs out at “11:11 on January 11, 2015” about one year later. “November 11, 2015” is stored in the non-volatile memory of the remote controller. Here, when the user notices that the battery has run out at 15:00 on January 11, 2015 and sets the time again at “15:10 on January 11, 2015”, when the battery is inserted, “January 11, 2015 Day 0:00 "is displayed. Since “2015” is displayed for “Year”, the “OK” button is pressed to confirm “2015”.

  Subsequently, since “January” is displayed for “Month”, the “OK” button is pressed to confirm “January”. Subsequently, since “11th” is displayed for “day”, the “decision button” is pressed to confirm “11th”. Thus, the user can set the date to “January 11, 2015” simply by pressing the enter button. Subsequently, “hour” is set to “15” and the enter button is pressed to confirm “15”. Subsequently, “10” is confirmed by pressing “OK” with “Minute” being set to “10”. In this way, the clock can be set to “January 11, 2015 15:10”.

  Next, when the user notices that the battery has run out, “January 12, 2015, 10:00” and sets the time again to “January 12, 2015, 10:20”. “January 12th 0:00” is displayed. Since “2015” is displayed for “Year”, the “OK” button is pressed to confirm “2015”. Subsequently, since “January” is displayed for “Month”, the “OK” button is pressed to confirm “January”.

Thus, the user can set “year” and “month” to “January 2015” simply by pressing the enter button. Subsequently, since “11 days” is displayed as “day”, “12 days” is confirmed by pressing the “OK” button in accordance with “12 days”. Subsequently, “hour” is set to “10” and the determination button is pressed to confirm “10”. Subsequently, “20” is confirmed by setting “20” to “20” and pressing the enter button. In this way, the clock can be set to “January 12, 2015 10:20”.
As described above, according to the present invention, when the user sets the clock, it is possible to save time and labor for setting all of the year / month / day / hour / minute.

  In addition to the air conditioner, the above control is a device with a calendar function such as a digital camera, video camera, watch, rice cooker, water heater, etc., and when the power is cut off, the device returns to the factory default state It is also possible to apply. In other words, it is effective as a calendar setting method for a device with a calendar function and a device having the setting method.

  The air conditioner includes a control device 31. The control device 31 includes a CPU, a ROM, a RAM, and a nonvolatile memory, and controls the refrigeration cycle so as to execute the set air conditioning operation in accordance with an instruction from the remote controller 21. When it is determined that the room temperature is considerably higher than the set temperature during the cooling operation, the control device 31 performs the cooling operation with the maximum cooling capacity.

  In this case, when the temperature of the conditioned air blown from the air outlet 16 of the indoor unit 2 becomes equal to or lower than the dew point temperature, condensation occurs on the inner wall near the air outlet 16 or the surface of the louver 17, and eventually the grown water droplets flow down and wet the room. was there.

  Therefore, in the present invention, the dew point temperature is calculated based on the room temperature and the room humidity, and there is a possibility that the water will fall if a condition that the indoor heat exchanger temperature is lower than the dew point temperature by a certain value or more has exceeded a predetermined time. The temperature of the conditioned air blown out from the indoor unit is increased by executing the control to decrease the rotational speed of the compressor and / or the control to increase the rotational speed of the indoor fan. Thereby, it is possible to avoid the risk of falling water because water droplets generated by condensation disappear or become smaller.

  FIG. 6 is a control block diagram of the control device 31. The air conditioner of the present invention includes an indoor fan 15, the indoor unit 2 in which the indoor heat exchanger 7 and the indoor fan 15 are accommodated, a room temperature sensor 32 that detects the indoor temperature, and a humidity sensor 33 that detects the indoor humidity. The refrigeration cycle of the refrigerant circuit is controlled based on the information detected by the indoor heat exchanger temperature sensor 34 that detects the temperature of the indoor heat exchanger, the room temperature sensor 32, the humidity sensor 33, and the indoor heat exchanger temperature sensor 34. And a control device 31. The control device 31 calculates a dew point temperature based on the room temperature and the room humidity detected by the room temperature sensor 32 and the humidity sensor 33, respectively, and an indoor heat exchanger temperature sensor for the dew point temperature. Control for reducing the rotational speed of the compressor 3 and / or the indoor fan 15 when a condition where the temperature of the indoor heat exchanger detected by 34 is lower than a predetermined value has passed for a predetermined time or longer. By executing a control that increases the rotational speed, increasing the temperature of the conditioned air blown from the indoor unit 2.

  The control performed by the control device 31 will be described in detail with reference to FIG. The control device 31 calculates the dew point temperature based on the room temperature and the room humidity detected by the room temperature sensor 32 and the humidity sensor 33, respectively, during the cooling operation. Then, the calculated dew point temperature is compared with the indoor heat exchanger temperature detected by the heat exchanger temperature sensor 34, and the condition that the indoor heat exchanger temperature is lower than the dew point temperature by a predetermined value or more is a predetermined time (this embodiment). Then, it is determined whether or not one hour has passed. Since various methods are known for calculating the dew point temperature, description thereof is omitted here, but the dew point temperature may be calculated using these known methods.

  When it is determined that the above condition is not satisfied, the dew point temperature is continuously measured. When it is determined that the above condition is satisfied, the rotational speed of the compressor 3 is controlled as a temperature increase control of the conditioned air. The control which lowers and / or the control which raises the rotation speed of the indoor fan 15 is performed. When the control device 31 determines that the temperature increase control of the conditioned air has been performed for a predetermined time (1 hour in the present embodiment), the control device 31 returns to the control of the original cooling operation.

In addition, when executing the temperature increase control of the conditioned air, the control device 31 executes the control to increase the rotation speed of the indoor fan only when the wind speed is set to the automatic operation mode. This is because, when the user is setting to operate at a constant wind speed, if the rotational speed of the indoor fan 15 is increased, it may be misunderstood that the air conditioner has failed. Therefore, in this case, the control is performed by reducing the rotation speed of the compressor 3. Alternatively, in the case where the wind speed is set to operate at a constant speed, control for increasing the rotation speed of the indoor fan may be performed after voice guidance. If it does in this way, it becomes possible to combine with the control which reduces the rotation speed of a compressor, and it is more effective in prevention of dew condensation.

  In the present invention, a fixture 41 that fixes a pipe connected to the four-way valve 9 is used. As pipes connected to the four-way valve 9, there are a discharge pipe 11, a heat exchanger side pipe 12, a three-way valve side pipe 13, and a suction side pipe 14, as shown in FIGS. If these pipes are placed apart, the handleability is poor. Therefore, as shown in FIG. 8, the pipes are unitized while being connected to the four-way valve 9 and are handled as a pipe assembly 42.

  The fixture 41 is fixed to the pipe in the state of the pipe assembly 42. The three pipes to which the fixture 41 is fixed are the discharge pipe 11, the three-way side pipe 13, and the suction side pipe 14 that extend in the vertical direction and have portions arranged in parallel to each other. About the heat exchanger side piping 12, since the direction of piping differs from said three piping, there is no possibility of contacting originally.

  As shown in FIG. 9, the pipe assembly 42 to which the fixture 41 is attached is fixed in the outdoor unit 1 after fixing the outdoor heat exchanger 4 and the compressor 3 on the bottom plate 43 as shown in FIG. 9. And pipe connection with brazing. As can be seen from FIGS. 9 and 10, the four-way valve 9 and the compressor 3 are accommodated in a narrow space separated from the outdoor fan 45 by the shielding plate 44 inside the outdoor unit 1. The

  Accordingly, the interval between the pipes 11, 13, and 14 is narrowed, and if an external force is applied during the transportation or installation of the outdoor unit, the pipes collide with each other, and there is a high risk of deformation or damage. By using 41, these dangers can be avoided.

  11 and 12 are perspective views showing the first embodiment of the fixture 41. FIG. The fixing device 41 is formed so as to overlap the hinge portion 47 and the main body 48 in which the end portions on one side of the pair of L-shaped members 46, 46 arranged with one side back to back are connected via the hinge portion 47. The central pipe holding part 49, the end pipe holding parts 50, 50 formed on the other side of the L-shaped members 46, 46, and the L-shaped members 46, 46 are in contact with each other. It has a binding band 51 as a fixing member that is fixed in a state (a state in which the main body is closed). In the figure, the binding band 51 is represented by a two-dot chain line.

  The other sides of the L-shaped members 46 and 46 are formed to be thicker than the one side, and are further formed to have a track shape in plan view with the L-shaped members 46 and 46 in contact with each other. Yes. The binding band 51 is fixed so as to hang around the side peripheral surface of the other side portion formed in a track shape. In order to prevent the binding band 51 from shifting, a guide groove portion 52 is formed at a boundary portion between one side and the other side of the L-shaped member 46, and a flange is formed at the upper edge portion of the end pipe holding portion 50. A portion 53 is formed. The binding band 51 is prevented from being displaced by being fitted in a space between the guide groove portion 52 and the flange portion 53.

  The main body 48 of the fixture 41 is integrally formed of a rubber material. Therefore, in this embodiment, as shown in FIG. 12, in a state where the main body is opened, a part of the central pipe holding part 49 functions as a hinge part 47 by elastic deformation. The central pipe holding portion 49 is formed in a cylindrical shape by combining L-shaped members. The end pipe holding part 50 has a shape in which a part of the cylindrical shape is cut out, and is formed in a substantially C shape in plan view.

In order to fix the fixture 41 to the pipe, the main body 48 is opened in the horizontal direction (see FIG. 12).
After the discharge pipe 11 of the pipe assembly 42 is introduced into the central pipe holding part 49, the main body 48 is closed as shown in FIG. Thereby, the discharge pipe 11 can be held in the central pipe holding part 49.

  Next, after holding the three-way side pipe 13 and the suction side pipe 14 at the two end pipe holding parts 50, 50, the binding band 51 is wound around to bind the L-shaped members 46, 46 together. At this time, since the end pipe support part 50 is formed of a rubber material, the end pipe support part 50 is elastically deformed by the fastening force of the binding band 51 and is in close contact with the pipe. As described above, the fixture 41 used in the present invention can be easily attached to the pipe, can securely fix the fixture 41 to the pipe, and can suppress the chatter noise of the pipe. It becomes possible.

  FIGS. 13-18 is a figure which shows 2nd embodiment of a fixing tool. The difference between the present embodiment and the first embodiment is that, in this embodiment, the L-shaped members 46 and 46 are opposed to the L-shaped members 46 and 46 on the front surface side of the front and back surfaces of the pair of L-shaped members 46 and 46. A convex portion 54 projecting toward the L-shaped member 46 and a concave portion 55 engaging with the convex portion 54 projecting from the opposing L-shaped member 46 are formed. This is the same as the embodiment.

  Further, claw portions 56 and 56 are formed at the tip portions of the convex portions 54 and 54, and claw receiving portions 57 and 57 are formed in the corresponding concave portions 55. According to the above configuration, the L-shaped members 46, 46 can be prevented from shifting in the vertical direction with the main body 48 closed, and can be temporarily fixed with the main body 48 closed. The bundling work by 51 can be performed easily.

  FIG. 19 is a plan view showing a third embodiment of the fixture. The difference between this embodiment and the second embodiment is that, in this embodiment, the fourth pipe holding portion 58 is formed near the center of the main body 48, and other configurations are the same as those of the second embodiment. Is done.

  As described above, the outdoor unit 1 accommodates a compressor, a four-way valve, an outdoor heat exchanger, a throttling device, and piping connecting these. The outdoor unit 1 is packed and shipped by a packing device. 23 to 27 are views showing the packing device of the present invention. The packaging device includes a bottom tray 61 on which the outdoor unit 1 is placed, and two cushioning materials 62 a and 62 b interposed between the outdoor unit 1 and the bottom tray 61. The buffer materials 62a and 62b are formed of a foamed resin such as foamed polystyrene. Since the cushioning material becomes unnecessary after unpacking, further weight reduction has been desired.

  Therefore, in the present invention, of the side surfaces of the cushioning materials 62a and 62b, a C surface processing with a chamfering width of 20 mm to 40 mm is performed on the upper end portion of the surface contacting the side peripheral surface of the bottom tray 61 (see the C surface processing portion 63) ). Thereby, it is possible to obtain a packaging device that can be reduced in weight while maintaining the functions (strength and buffering function) as the packaging device. Moreover, since the foaming resin used for a buffer material reduces by weight reduction, it is good also for an environment.

  That is, of the side surfaces of the cushioning materials 62a and 62b, the upper end portion of the surface in contact with the side peripheral surface of the bottom tray 61 is a portion that is less likely to be affected by the impact when dropped in a state where the outdoor unit is packed. Therefore, after packing the outdoor unit using cushioning materials obtained by cutting this part into various shapes, a drop test of the outdoor unit was performed.

As a result, of the side surfaces of the cushioning materials 62a and 62b, when the C surface processing with a chamfering width of 20 mm to 40 mm was performed on the upper end portion of the surface contacting the side peripheral surface of the bottom tray 61, the C surface processing was not performed. It was found that weight reduction was possible while maintaining the same strength and function as the material. Here, the C surface processing means that both sides of the corner portion C are chamfered with equal width w as shown in FIG.
Although the embodiments of the present invention have been described above, the scope of the present invention is not limited to these embodiments, and various modifications can be made without departing from the spirit of the invention.
<Appendix>
In order to achieve the above object, an air conditioner according to another aspect of the present invention includes a refrigerant circuit in which a compressor, a four-way valve, an outdoor heat exchanger, an expansion device, and an indoor heat exchanger are connected by piping, A fixture that fixes the pipe connected to the four-way valve, and the fixture is connected to the ends of one side of a pair of L-shaped members arranged side by side via hinges. In the state where the main body, the central pipe holding part formed near the hinge part, the end pipe holding part formed at the end part on the other side of each L-shaped member, and the L-shaped members are in contact with each other A fixing member that fixes both, and the main body is capable of introducing a pipe by opening a central pipe holding part by separating a pair of L-shaped members, and further introducing a pipe into the central pipe holding part The central pipe holder is closed by bringing a pair of L-shaped members close together Characterized by holding the pipe.
According to the above configuration, when fixing three pipes, one pipe opens the main body of the fixture (the L-shaped member is rotated around the hinge portion to separate the two pipes). After being introduced into the central pipe holder, it can be held in the central pipe holder just by closing the main body (by turning the L-shaped member around the hinge part to bring them closer together). The amount of work is the same as fixing two pipes with a conventional fixture. That is, it is possible to reliably fix the three pipes with the same work amount as attaching one conventional fixture to the two pipes.
The material of the fixture is not particularly limited, and an L-shaped member formed separately may be connected via a hinge as a hinge portion, or the main body of the fixture is integrally formed of a resin material or a rubber material, The L-shaped member can be rotated by deforming the main body as the hinge portion. In this case, the manufacturing cost of the main body can be reduced.
When the main body is made of a resin material, a thin portion may be formed as the hinge portion. Moreover, if the main body is formed of a rubber material, the main body can be elastically deformed, and the main body can be easily opened and closed. In addition, the vibration damping performance of the rubber material makes it possible to suppress chatter noise that occurs when the piping vibrates due to the operation of the compressor. The central pipe holding part is formed in the vicinity of the hinge part, but a part of the central pipe holding part can also be used as the hinge part.
An end pipe holding part is formed in a U shape or a C shape in plan view, and the L-shaped member is formed by hanging a binding tool around two end pipe holding parts formed on the main body as the fixture. It is also possible to bind the pipes together and hold the pipes in the end pipe holding part. According to the above configuration, the central pipe holding part can be maintained in a closed state by the binding tool so that the central pipe holding part is not opened and the pipe falls out, and the end pipe holding part is hung around by the binding tool. This makes it possible to close the end pipe holding portion formed in a U shape or a C shape. Thereby, it is possible to prevent the pipes from falling off all the pipe holding parts.
If the main body is made of a rubber material, the pipe holding part can be tightly attached to the pipe and held without gaps by tightening the end pipe holding part with a binding tool, and the chatter noise of the pipe can be more effectively suppressed. be able to.
On either one of the front surface side and the back surface side of the pair of L-shaped members, each L-shaped member protrudes toward the facing L-shaped member and protrudes from the facing L-shaped member. It can also be set as the structure in which the recessed part engaged with each was formed.
According to the above configuration, the L-shaped member can be prevented from shifting in the vertical direction with the main body closed, and the work can be easily performed during the fixing work by the fixing member, particularly the binding work by the binding tool. be able to.
Furthermore, by forming a claw part on the convex part and a claw receiving part on the concave part, it is possible to temporarily fix the main body in a closed state, and it is possible to perform the fixing work or the bundling work more easily Become. In addition, what is necessary is just to form a nail | claw part and a nail | claw receiving part in at least one set among the sets of the convex part and recessed part which exist in two pairs.
