Description

Technical Field

[0001] The present disclosure relates to an air conditioner using a refrigeration cycle. Background Art

[0002] Conventional air conditioners have the following situation: when cooling operation starts, the temperature of components such as wires located near a heat exchanger is lower than the air temperature inside the air conditioner, so water droplets caused by condensation are generated on these devices and components. Therefore, an air conditioner is proposed, which has: a drain pan for collecting and storing water droplets caused by the condensation falling from the heat exchanger, etc., that is, condensed water, and a drain pump for drawing up the condensed water collected in the drain pan and discharging it outside the housing of the air conditioner (for example, refer to Patent Document 1).

[0003] Patent Document 1: Japanese Patent Application Publication No. 2016-223667

[0004] The air conditioner of Patent Document 1 has the following situation: when the cooling operation starts, the temperature of the components such as the drain pump and the wires located near the drain pump is lower than the air temperature inside the air conditioner, so water droplets caused by condensation are generated on these devices and components. For example, in the air conditioner of Patent Document 1, since the condensed water drawn by the drain pump is cold water, there is a case where condensation is generated on the outer surface of the drain pump through which the condensed water flows. In addition, there is a case where the condensed water generated on other components other than the wires is transferred to the outer surface of the wires in contact with the components and adheres to the wires.

[0005] In the air conditioner of Patent Document 1, if condensation adheres to the drain pump or the drain pump wire connected to the drain pump, the condensed water composed of the condensed water flows downward from the generating position due to gravity. In the case where the drain pump wire connecting the drain pump and the electrical box is configured to be directed downward from the connection part on the electrical box side to the connection part on the drain pump side, that is, the drain pump is configured below the electrical box, the condensed water flows along the drain pump wire to the connection part on the drain pump side. In this case, the air conditioner has a situation where the condensed water adheres to the wire terminal that becomes the connection part on the drain pump side, causing corrosion on the wire terminal. Summary of the invention

[0006] The present disclosure has been made to solve the above-mentioned problems, and an object of the present disclosure is to provide an air conditioner that suppresses the condensed water from adhering to the lead terminal along the drain pump lead even if the condensed water is adhering to the drain pump lead.

[0007] The air conditioner disclosed in the present invention houses a heat exchanger and a blower inside a shell, wherein the air conditioner comprises: an electrical box that houses circuit components used in the air conditioner; a drain pan that is arranged below the heat exchanger to receive condensed water; a drain pump that is arranged above the drain pan to drain water accumulated in the drain pan; and a pump wire that electrically connects the drain pump to the electrical box, the drain pump comprising: a pump body that includes a wire terminal to which one end of the pump wire is connected, and is formed with a suction port and a discharge port to draw water accumulated in the drain pan and discharge it; and a wire hook that is arranged on the side of the pump body and maintains the wiring position of the pump wire, the wire hook is in the wiring path of the pump wire from the wire terminal toward the electrical box, fixes the pump wire to face downward from the wire terminal, and fixes it to face upward from the lowermost part of the pump wire.

[0008] The air conditioner disclosed in the present invention has a wire hook, which is arranged on the side of the pump body and holds the wiring position of the pump wire. The wire hook fixes the pump wire from the wire terminal to the electrical box in the wiring path of the pump wire, so that it is directed downward from the wire terminal, and is fixed upward from the lowermost part of the pump wire. The air conditioner uses the wire hook to fix the wiring path of the above-mentioned pump wire, thereby preventing condensed water from flowing along the pump wire toward the wire terminal. Therefore, even if condensed water adheres to the pump wire, the air conditioner can prevent the condensed water from adhering to the wire terminal along the pump wire.

[0021] [Overall Structure of Air Conditioner 100]

[0022] Figure 1 It is a perspective view of the air conditioner 100 according to the embodiment. Figure 2 1 is an exploded perspective view of the air conditioner 100 according to the embodiment. Figure 1 and Figure 2 The overall structure of the air conditioner 100 will be described. Figure 1 and Figure 2 The Z-axis direction shown indicates the up-down direction, the Y-axis direction indicates the front-back direction, and the X-axis direction indicates the left-right direction.

[0023] In more detail, when describing the direction of the air conditioner 100, the direction from the center of the housing 1 to the panel 2 described later is defined as the downward direction Z2, and the opposite direction thereof is defined as the upward direction Z1. The downward direction Z2 is the direction of gravity when the air conditioner 100 is installed. In addition, the direction from the center of the outer surface of the panel 2 to the panel outlet 2a is defined as the front direction Y1, and the opposite direction thereof is defined as the rear direction Y2. In addition, the right direction when viewing the housing 1 from the front of the panel 2 is defined as the right direction X2, and the opposite direction thereof is defined as the left direction X1.

[0024] The air conditioner 100 is a device that adjusts the temperature and humidity of the air in the indoor space to be conditioned and performs air conditioning. The air conditioner 100 is a refrigeration cycle device that forms a refrigerant circuit in which a compressor, a condenser, an expansion valve, and an evaporator are connected by piping, and a heat exchanger 6 and a blower 5 that function as a condenser or an evaporator are accommodated inside a casing 1 to constitute an indoor unit installed indoors.

[0025] Air conditioner 100 Figure 1 and Figure 2 The air conditioner 100 is described as a ceiling embedded type device installed on the back of the ceiling of the room, but it is not limited to the ceiling embedded type device, and can also be a floor-standing type, ceiling-mounted type device, wall-mounted type device, etc. In addition, the air conditioner 100 is not limited to an indoor unit in the refrigeration cycle device, and can also be an outdoor unit that contains a heat exchanger 6 and a blower 5 that function as a condenser or an evaporator inside the housing 1 and is installed outdoors.

[0026] The air conditioner 100 includes a casing 1 and a panel 2. The casing 1 and the panel 2 are combined to form the outer shape of the air conditioner 100. The air conditioner 100 is formed into a box shape by combining the casing 1 and the panel 2, and a space constituting an air passage for air circulation is formed inside.

[0027] As an example, Figure 1 and Figure 2 As shown, the outer contour of the air conditioner 100 is formed in a rectangular parallelepiped shape. In addition, the outer contour of the air conditioner 100 is not limited to a rectangular parallelepiped shape, and can be formed in other shapes such as a polygonal column, a cylindrical shape, or a spherical shape as long as it is formed in a box shape with a space inside.

[0028] like Figure 2 As shown, the shell 1 is a box-shaped component in which five surfaces except the bottom are formed by walls. The shell 1 is formed in the shape of a rectangular container having an upper surface, a right side surface, a left side surface, a front surface and a rear surface. The shell 1 has a top plate portion 1d and a side wall portion 1e constituting each of the four side surfaces. In addition, the side wall portion 1e on the right side of the shell 1 to which the end of the drain hose 72 described later is mounted is referred to as the right side wall portion 1e1. An opening portion 1a is formed on the surface on the lower surface side of the shell 1. The shell 1 includes a partition 11 inside the shell 1. The partition 11 is arranged in the central portion of the shell 1 in the front-to-back direction (Y-axis direction), and divides the internal space of the shell 1 into two parts in the front-to-back direction (Y-axis direction).

[0029] The partition plate 11 is a member that divides the internal space of the housing 1 into a blower chamber 1b in which the blower 5 is installed and a heat exchanger chamber 1c in which the heat exchanger 6 is installed. The internal space of the housing 1 is divided into the blower chamber 1b and the heat exchanger chamber 1c by the partition plate 11. The partition plate 11 forms a flow path for air from the blower chamber 1b to the heat exchanger chamber 1c in the internal space of the housing 1. The partition plate 11 is formed with a partition plate hole 11a (see Figure 5 and Figure 7 The partition hole 11a constitutes a through hole. Lead wires such as a pump lead wire 76 and a switch lead wire 84 described later are inserted through the partition hole 11a.

[0030] The blower chamber 1b is formed in a box shape and houses a later-described electric device box 3, a terminal block 4, and a blower 5. A net 10 is disposed on the lower surface side of the blower chamber 1b in the opening 1a of the casing 1.

[0031] The heat exchanger chamber 1c is box-shaped and contains a heat exchanger 6, a drain pump 7, and a water level measuring device 8. A drain pan 9 for receiving condensed water is disposed on the lower surface of the heat exchanger chamber 1c at the opening 1a of the housing 1.

[0032] The panel 2 is mounted on the housing 1 in such a manner as to block the opening 1a on the lower surface side of the housing 1. The panel 2 is mounted on the housing 1 from below the housing 1 in a state of covering the drain pan 9 and the net 10. When the air conditioner 100 is mounted on the ceiling, the panel 2 is located on the lower surface of the housing 1 and forms the outer appearance of the air conditioner 100.

[0033] In the front-to-back direction (Y-axis direction) of the air conditioner 100, a panel blow-out port 2a is formed on the front side of the panel 2 for the air discharged from the inside of the housing 1 to the outside. In the front-to-back direction (Y-axis direction) of the air conditioner 100, a panel suction port 2b is formed on the rear side of the panel 2 for the air flowing from the outside of the housing 1 to the inside.

[0034] Figure 3 It is a bottom view of the air conditioner 100 according to the embodiment with the panel 2 removed. Figure 4 It is a bottom view of the air conditioner 100 according to the embodiment, in a state where the panel 2, the drain pan 9, and the net 10 are removed. Figure 5 The air conditioner 100 according to the embodiment is in a state where the right side wall portion 1e1 of the casing 1 is removed. Figure 3 The air conditioner 100 is shown in the A direction view. Figure 6 Observe along the viewing direction Figure 3 The cross-sectional view of the air conditioner 100 taken along the line BB is shown. Figure 3 to Figure 6 The internal structure of the air conditioner 100 will be described.

[0035] The air conditioner 100 has an electrical box 3, a drain pump 7, and a drain pan 9. In addition, the air conditioner 100 has a terminal block 4, a blower 5, a heat exchanger 6, a water level measuring device 8, and a net 10. In addition, the air conditioner 100 has a pump wire 76 and a switch wire 84. The air conditioner 100 accommodates the electrical box 3, the terminal block 4, the blower 5, the heat exchanger 6, the drain pump 7, the water level measuring device 8, the pump wire 76, and the switch wire 84 in the internal space of the housing 1. The air conditioner 100 is equipped with a drain pan 9 and a net 10 in the opening 1a on the lower surface side of the housing 1.

[0036] The electrical box 3 is a box-shaped component. The electrical box 3 contains devices such as circuit components used to control the air conditioner 100. The devices contained in the electrical box 3 supply power to various devices of the air conditioner 100, and communicate with various devices constituting the air conditioner 100 to send and receive signals.

[0037] The electrical box 3 is arranged in the blower room 1b through which the indoor air flowing in from the panel suction port 2b passes. Figure 4 , Figure 5 As shown, the electric device box 3 is fixed to the upper part of the housing 1 so as to be located at the rear right side of the housing 1 with the partition plate 11 as the boundary. The electric device box 3 is fixed to the inside of the housing 1 by a fixing member such as screws.

[0038] The terminal block 4 is a component that stores only the terminals of the receiving wires that need to be pulled out and inserted when installing the air conditioner 100 among the circuit components accommodated in the electrical box 3 so as not to open the electrical box 3. For example, a plug of wiring connected to an external commercial power source is connected to the terminal block 4.

[0039] The terminal block 4 is arranged in the blower room 1b. Figure 4 As shown, the terminal block 4 is located on the rear side of the housing 1 with the partition plate 11 as a boundary and is fixed inside the housing 1 so as to be located in the space between the two blowers 5 .

[0040] The blower 5 takes air from the panel suction port 2b of the panel 2 into the housing 1, exchanges heat between the taken air and the refrigerant flowing in the heat exchanger 6, and discharges the heat-exchanged air from the panel blower port 2a of the panel 2. The blower 5 forms an air flow inside the housing 1.

[0041] like Figure 4 and Figure 5 As shown, the blower 5 includes a fan 55, a fan motor fixing member 51, a fan motor 52, a fan motor shaft 52a, and a fan cover 53. The fan 55 is mounted on the fan motor 52 via the fan motor shaft 52a, and is rotated by the fan motor 52 driven by a signal received from a circuit component in the electrical box 3.

[0042] like Figure 4 and Figure 5 As shown, the air conditioner 100 is provided with a blower 5 in the center of the rear of the housing 1 on the side of the panel air inlet 2b, with the partition 11 as the boundary. The blower 5 fixes a fan motor 52 via a fan motor fixing member 51 provided on the top plate 1d of the housing 1, and fixes a fan 55 to a fan motor shaft 52a extending to both sides of the fan motor 52.

[0043] The fan motor 52 receives a signal from the circuit components in the electrical box 3 and rotates. The fan 55 is a centrifugal blower such as a multi-blade fan, and is covered by a fan cover 53. The fan cover 53 forms a flow path for taking the air flowing in from the panel inlet 2b of the panel 2 to the fan 55 and making it flow to the heat exchanger 6. The air flowing due to the rotation of the fan 55 passes through the inside of the fan cover 53 and passes through the shell outlet 53a (see FIG. 5A ) of the fan cover 53. Figure 2 ) flows through the flow path of the partition 11 connected thereto and flows to the heat exchanger 6 located in front of it.

[0044] The heat exchanger 6 performs heat exchange between the refrigerant flowing inside the heat exchanger 6 and the air supplied from the blower 5. The heat exchanger 6 adjusts the temperature and humidity of the air sucked into the casing 1 from outside and blown from the casing 1 to the air-conditioned space.

[0045] The heat exchanger 6 functions as a condenser during heating operation to condense and liquefy the refrigerant. In addition, the heat exchanger 6 functions as an evaporator during cooling operation to evaporate and vaporize the refrigerant. The heat exchanger 6 is arranged at a position opposite to the shell discharge port 53a of the blower 5, and is arranged in the shell 1 on the air path of the air discharged by the blower 5.

[0046] like Figure 4 and Figure 5 As shown, the heat exchanger 6 is disposed in the heat exchanger chamber 1c. The air conditioner 100 has the heat exchanger 6 disposed in the front center of the casing 1 and the blower 5 disposed behind it via the partition plate 11. The heat exchanger 6 is mounted on the upper part of the casing 1.

[0047] The drain pump 7 is a pump that draws the condensed water collected in the drain pan 9. The drain pump 7 is arranged above the drain pan 9 and discharges the water accumulated in the drain pan 9. The drain pump 7 draws the condensed water collected in the drain pan 9 and discharges it to the outside through the drain hose 72 described later. During the cooling operation of the air conditioner 100, the drain pump 7 draws the condensed water accumulated in the drain pan 9 and discharges it to the outside from the housing 1 of the air conditioner 100. The drain pump 7 receives a signal from the circuit components in the electrical box 3 and operates. In addition, the detailed structure of the drain pump 7 is described later.

[0048] The water level measuring device 8 is a sensor for detecting the water level of the condensed water collected in the drain pan 9. The water level detection by the water level measuring device 8 is used to control the operation of the air conditioner 100. For example, the air conditioner 100 detects the water level of the condensed water by the water level measuring device 8, and when the drain pump 7 fails, the control device (not shown) of the air conditioner 100 stops the operation of the air conditioner 100, thereby preventing the condensed water from overflowing from the drain pan 9. In addition, the detailed structure of the water level measuring device 8 will be described later.

[0049] Figure 7 1 is an exploded view showing a component group including a drain pump 7 and a water level measuring device 8 of an air conditioner 100 according to an embodiment. The air conditioner 100 includes a base member 13 and a pump and switch fixing member 70. The drain pump 7 and the water level measuring device 8 are mounted on the housing 1 using the base member 13 and the pump and switch fixing member 70. That is, the air conditioner 100 includes the base member 13 and the pump and switch fixing member 70 in order to fix the drain pump 7 and the water level measuring device 8 to the housing 1.

[0050] A base member 13 is mounted on the top plate 1d constituting the upper surface of the housing 1, and a pump and switch fixing member 70 is mounted on the base member 13 so as to be suspended from below the base member 13. Furthermore, a drainage pump 7 and a water level measuring device 8 are mounted on the lower surface of the pump and switch fixing member 70.

[0051] The pump and switch fixing member 70 is formed in a plate shape. The pump and switch fixing member 70 is used to fix the water level measuring device 8 and the drainage pump 7 inside the housing 1, and the water level measuring device 8 and the drainage pump 7 are fixed to the pump and switch fixing member 70. The drainage pump 7 and the water level measuring device 8 are provided to extend downward relative to the top plate portion 1d.

[0052] The drain pump 7 and the water level measuring device 8 are arranged on the right side (X2 side) of the heat exchanger 6 in the heat exchanger chamber 1c. Alternatively, the drain pump 7 and the water level measuring device 8 may be arranged on the left side (X1 side) of the heat exchanger 6 in the heat exchanger chamber 1c. The drain pump 7 and the water level measuring device 8 are mounted on the pump and switch fixing member 70 in such a manner that the drain pump 7 is arranged on the rear side (Y2 side) of the housing 1 and the water level measuring device 8 is arranged on the front side (Y1 side) of the housing 1 in the heat exchanger chamber 1c of the housing 1.

[0053] The drain pan 9 is a dish-shaped component that collects condensed water generated by the air cooled by the heat exchanger 6 during cooling operation. Figure 3 , Figure 5 , Figure 6 As shown, the drain pan 9 is provided as a part constituting the lower surface side of the heat exchanger chamber 1c. The drain pan 9 is installed on the housing 1 from below the housing 1 in a manner covering the heat exchanger 6, the drain pump 7, and the water level measuring device 8. The drain pan 9 is used to receive water droplets such as condensed water falling from the equipment such as the heat exchanger 6 and the drain pump 7 arranged around the heat exchanger 6.

[0054] The drain pan 9 is arranged below the heat exchanger 6 and the drain pump 7 to receive condensed water such as condensed water falling from the heat exchanger 6 and the drain pump 7 and other equipment arranged around the heat exchanger 6. More specifically, the drain pan 9 is arranged below the group of components generating condensed water such as the heat exchanger 6, the drain pump 7 and the water level measuring device 8, in front of the partition 11, where the group of components generating condensed water such as the heat exchanger 6, the drain pump 7 and the water level measuring device 8 are arranged.

[0055] like Figure 2 , Figure 3 , Figure 5 As shown, the net 10 is provided as a part constituting the lower surface side of the blower chamber 1b. The net 10 is a part that covers the blower 5 to prevent fingers from being accidentally caught in the fan 55 as a movable part when the part on the panel suction port 2b side of the panel 2 is opened. The net 10 is installed on the housing 1 from the bottom of the housing 1 in a manner that covers a part of the blower 5, the electrical box 3, and the terminal block 4.

[0056] like Figure 2 and Figure 3 As shown, the net 10 includes a fan receiving portion 10a into which a part of the lower portion of the fan cover 53 is embedded, and a net-shaped net portion 10b. The net-shaped net portion 10b forms a mesh through which air flows from the panel suction port 2b of the panel 2 toward the fan 55 of the blower 5. The gaps in the mesh of the net-shaped net portion 10b are formed to be of a size that a human finger cannot pass through.

[0057] (Detailed Structure of Drain Pump 7)

[0058] Figure 8It is a perspective view of a component group such as the drain pump 7 and the water level measuring device 8 of the air conditioner 100 according to the embodiment. Fig. 9 1 is an exploded perspective view of a component group including a drain pump 7 and a water level measuring device 8 of the air conditioner 100 according to the embodiment. Figure 8 The pump lead wire 76 and the switch lead wire 84 shown are omitted diagrams showing the lead wires extending to the partition hole 11 a.

[0059] The drain pump 7 has a pump body 71 as a main part having a pump function, and a wire hook 77 for holding the position of a pump wire 76. In addition, the drain pump 7 has a drain hose 72 connected to the pump body 71 and a drain pipe sleeve 73 provided at the end of the drain hose 72.

[0060] The drain pump 7 also includes a pump fixing member 74 for fixing the pump body 71 to the pump and switch fixing member 70, an upper fixing member 741, a lower fixing member 742, and a vibration-proof rubber 75. The drain pump 7 also includes a wire clamp 78 for holding the position of the pump wire 76, and a hook fixing member 79 for fixing the wire hook 77.

[0061] The pump body 71 includes a lead terminal 76a connected to one end of the pump lead 76, and is formed with a suction port 7a and a discharge port 7b, and draws water accumulated in the drain pan 9 and discharges it. The pump body 71 is a pump that draws water and discharges the drawn water, for example, a pump with an impeller that is operated by electricity. The pump body 71 is formed in a cylindrical shape, and the suction port 7a is provided at the lower end to obtain condensed water in the drain pan 9, and the discharge port 7b for discharging condensed water is provided in the circumferential direction above the suction port 7a.

[0062] The pump body 71 is disposed above the drain pan 9, draws condensed water on the drain pan 9 from the suction port 7a, and discharges it from the discharge port 7b to the drain hose 72. The pump body 71 is attached to the lower surface side of a pump fixing member 74 described later.

[0063] The drain hose 72 is connected to the discharge port 7b of the pump body 71, and discharges the condensed water drawn by the pump body 71 to the outside of the housing 1. The condensed water accumulated in the drain pan 9 is forcibly drawn from the drain pan 9 by the power of the pump body 71, and is discharged to the outside of the housing 1 through the drain hose 72, and then discharged outdoors.

[0064] like Figure 8 and Fig. 9As shown, the drain hose 72 is a curved pipe whose upper and lower ends are bent into an L shape. The drain hose 72 includes an extension portion 72a extending in the up-down direction, a pump connection portion 72b provided at the lower end of the extension portion 72a and connected to the discharge port 7b, and a shell connection portion 72c provided at the upper end of the extension portion 72a and connected to the shell 1. The portion between the extension portion 72a and the pump connection portion 72b of the drain hose 72 is bent, and the portion between the extension portion 72a and the shell connection portion 72c is bent.

[0065] When viewed along the flow direction of condensed water, the drain hose 72 is formed at the pump connection portion 72b to extend from the discharge port 7b to the rear of the housing 1, and is formed at the extension portion 72a to extend upward. In addition, the drain hose 72 is formed at the housing connection portion 72c provided at the upper end of the extension portion 72a to extend in the right direction.

[0066] A drain sleeve 73 is provided at the housing connection portion 72c of the drain hose 72. The drain sleeve 73 is provided at the end of the drain hose 72 on the opposite side to the pump body 71. The drain sleeve 73 is used to attach the drain hose 72 to the side wall portion 1e of the housing 1 (see Figure 7 The housing connection portion 72 c of the drain hose 72 is inserted into a through hole 1 e 2 formed in the right side wall portion 1 e 1 of the housing 1 , and penetrates the side wall portion 1 e of the housing 1 .

[0067] like Figure 8 and Fig. 9 As shown, the pump fixing member 74 is a member that serves as a base for the pump body 71 and is disposed between the pump body 71 and the pump and switch fixing member 70 when the pump body 71 is mounted on the pump and switch fixing member 70 .

[0068] The pump fixing member 74 is mounted on the pump and switch fixing member 70. The pump fixing member 74 is disposed between the pump body 71 and the pump and switch fixing member 70 as a base for the pump body 71, and the pump body 71 is mounted so that the suction port 7a of the pump body 71 faces downward where the drain pan 9 is disposed.

[0069] like Fig. 9 As shown, the pump fixing member 74 includes a flat-plate-shaped pedestal base portion 74a, a flat-plate-shaped pedestal mounting portion 74c opposite to the pedestal base portion 74a, and a pedestal side wall portion 74b extending in the up-down direction between the pedestal base portion 74a and the pedestal mounting portion 74c to form a side wall. The pedestal base portion 74a, the pedestal side wall portion 74b, and the pedestal mounting portion 74c are formed integrally.

[0070] The pump fixing component 74 is provided with a pedestal base portion 74a at the lower end of the pedestal side wall portion 74b, and a pedestal mounting portion 74c is provided at the upper end of the pedestal side wall portion 74b, and a space is formed between the pedestal base portion 74a and the pedestal mounting portion 74c in the up and down direction (Z-axis direction).

[0071] The pump fixing member 74 is mounted and fixed to the pump and switch fixing member 70 through an upper fixing member 741. The upper fixing member 741 is, for example, a screw or a bolt and a nut. The pump fixing member 74 fixes the pump and switch fixing member 70 and the pedestal mounting portion 74c through the upper fixing member 741. A vibration-proof rubber 75 is arranged between the pump and switch fixing member 70 and the pedestal mounting portion 74c, so that the vibration of the pump body 71 is not easily transmitted to the pump and switch fixing member 70.

[0072] The pump body 71 is mounted and fixed to the pedestal base portion 74a of the pump fixing member 74 by the lower fixing member 742. The lower fixing member 742 is, for example, a screw or a bolt and a nut. The pump body 71 is mounted on the lower surface side of the pedestal base portion 74a. The pump fixing member 74 holds the pump body 71 in a state where the pump body 71 is suspended below the pump fixing member 74.

[0073] The pump lead 76 is an electric wire for supplying power to the pump body 71 of the drain pump 7. The pump lead 76 is connected to the pump body 71 of the drain pump 7 and the electric box 3, and electrically connects the drain pump 7 to the electric box 3. In order to supply power or an electric signal to the drain pump 7, one end of the pump lead 76 is connected to the pump body 71, and the other end is connected to the electric box 3.

[0074] like Figure 8 and Fig. 9 As shown, a lead terminal 76a is provided on the pump body 71. The lead terminal 76a is an inlet and outlet of current provided for connecting a circuit, and is a portion connected to one end of the pump lead 76. In addition, the lead terminal 76a may also include an end of the pump lead 76 connected to the lead terminal 76a.

[0075] The wire hook 77 is disposed adjacent to the side of the pump body 71 and is used to maintain the position where the pump wire 76 is wired. The wire hook 77 fixes the pump wire 76 from the wire terminal 76a to the electric device box 3, and fixes the pump wire 76 from the lowermost portion to the upper side. The wire hook 77 bends the pump wire 76 into a U-shape for wiring, and the U-shaped portion forms a drainage bend shape.

[0076] The wire hook 77 is attached to the pump fixing member 74 by attaching the upper portion thereof to the pump fixing member 74 via a hook fixing member 79 and fixed to the pump fixing member 74. The hook fixing member 79 is, for example, a screw, a bolt, and a nut. The wire hook 77 is attached to the pump fixing member 74 in a suspended manner from the pump fixing member 74.

[0077] The wire hook 77 is provided so as to be located on the front side (Y1 side) relative to the pump fixing member 74. In addition, the wire hook 77 is provided so as to be located on the front side (Y1 side) relative to the pump body 71. In addition, the position of the wire hook 77 is not limited to being located on the front side (Y1 side) relative to the pump body 71, and may be determined in consideration of the position of the wire terminal 76a, the relationship with other components, maintenance, etc.

[0078] Fig.10 1 is a perspective view of the wire hook 77 of the air conditioner 100 according to the embodiment. Figure 8 to Figure 10 , the structure of the wire hook 77 will be described. The wire hook 77 has a hook mounting portion 77a, a hook middle portion 77b, a hook lower portion 77c including a first hook 771, and a second hook 772. The wire hook 77 is a component having at least two hook-shaped portions, the first hook 771 and the second hook 772.

[0079] The hook mounting portion 77a is formed in a plate shape. The hook mounting portion 77a constitutes a wall extending in the left-right direction (X-axis direction) and in the up-down direction (Z-axis direction) in the housing 1. The plate surface of the hook mounting portion 77a is formed to face the front-back direction (Y-axis direction). The hook mounting portion 77a is provided above the hook intermediate portion 77b.

[0080] like Fig. 9 As shown, the hook mounting portion 77a is mounted on the pedestal side wall portion 74b. The hook mounting portion 77a is formed with a screw fixing hole 77a1 constituting a through hole. The screw fixing hole 77a1 is inserted through the hook fixing member 79. The wire hook 77 is mounted on the pedestal side wall portion 74b of the pump fixing member 74 by the hook fixing member 79 inserted through the screw fixing hole 77a1, and is fixed to the pump fixing member 74.

[0081] The hook middle portion 77b is formed in a plate shape. The hook middle portion 77b is a member located between the hook mounting portion 77a and the hook lower portion 77c in the vertical direction (Z-axis direction). The hook middle portion 77b forms an inclined surface. The hook middle portion 77b is inclined so that the hook mounting portion 77a is located above and close to the pump body 71 relative to the hook lower portion 77c, and the hook lower portion 77c is located below and away from the pump body 71 relative to the hook mounting portion 77a. Figure 8 As shown, the hook intermediate portion 77 b enables the pump wire 76 routed between the first hook 771 and the second hook 772 to follow the inclined surface.

[0082] The hook lower portion 77c is formed in a plate shape. The hook lower portion 77c constitutes a wall extending in the left-right direction (X-axis direction) and in the up-down direction (Z-axis direction) in the housing 1. The plate surface of the hook lower portion 77c is formed to face the front-back direction (Y-axis direction). The hook lower portion 77c is provided below the hook middle portion 77b. The first hook 771 is provided at the lower end portion 77c1 of the hook lower portion 77c.

[0083] The first hook 771 supports the pump wire 76. The first hook 771 is a portion located below the wire terminal 76a and hooked with the pump wire 76 to hold the pump wire 76. When the operator hooks the pump wire 76 on the first hook 771, the first hook 771 can hold the pump wire 76.

[0084] The first hook 771 includes a lower edge portion 77c2 and a hook-shaped portion 771a. The lower edge portion 77c2 is a portion forming the lower edge of the hook lower portion 77c. The hook-shaped portion 771a is a portion provided to protrude downward from a portion of the lower edge portion 77c2.

[0085] The hook-shaped portion 771a is formed in a hook shape. The hook-shaped portion 771a is formed in a J-shape or a J-shape that is reversed left and right. The pump wire 76 is arranged between the hook-shaped portion 771a and the lower edge portion 77c2. The first hook 771 forms a notch portion 77c3 by the lower edge portion 77c2 and the inner edge of the hook-shaped portion 771a. The notch portion 77c3 forms a hook opening portion 77c4 between the front end portion of the hook-shaped portion 771a and the lower edge portion 77c2. The pump wire 76 is inserted into the notch portion 77c3 through the hook opening portion 77c4 and is held by the hook-shaped portion 771a and the lower edge portion 77c2.

[0086] The pump lead 76 is bent into a U shape and includes a lead lowermost end portion 76 b which is the lowermost portion bent into the U shape. The lead lowermost end portion 76 b is disposed on the first hook 771 and is located at the lowermost portion of the pump lead 76 on the wiring path between the lead terminal 76 a and the second hook 772 .

[0087] The wire lowermost end 76b is arranged between the hook 771a and the lower edge 77c2 of the hook lower portion 77c, and the first hook 771 supports the wire lowermost end 76b. The wire hook 77 clamps the wire lowermost end 76b of the pump wire 76 with the hook 771a and the lower edge 77c2 of the hook lower portion 77c.

[0088] The lowermost end 76b of the wire is formed to be located below the wire terminal 76a. In other words, the first hook 771 is formed to be located below the wire terminal 76a, and the hook-shaped portion 771a and the lower edge portion 77c2 are formed to be located below the wire terminal 76a. The pump wire 76 located between the lowermost end 76b of the wire and the wire terminal 76a is wired so as to extend in the vertical direction. That is, the portion of the pump wire 76 between the wire terminal 76a and the first hook 771 is wired so as to extend in the vertical direction.

[0089] The hook-shaped portion 771a of the first hook 771 includes a front end protrusion 771b at the front end. The front end protrusion 771b is formed at the front end of the hook-shaped portion 771a so as to extend toward the lower edge 77c2 of the hook lower portion 77c. The wire hook 77 is configured so that the lowermost end 76b of the wire disposed between the hook-shaped portion 771a and the lower edge 77c2 is not easily dropped by including the front end protrusion 771b at the front end of the hook-shaped portion 771a.

[0090] The second hook 772 supports the pump wire 76. The second hook 772 is located above the first hook 771 and is located closer to the electric box 3 than the first hook 771, and is a portion for hooking the pump wire 76 and holding the pump wire 76. When the operator hooks the pump wire 76 on the second hook 772, the second hook 772 can hold the pump wire 76.

[0091] The second hook 772 is formed in a U-shape with an open top when viewed from the side of the housing 1. The second hook 772 supports the pump lead 76. The pump lead 76 is arranged on the second hook 772 at a position closer to the electric device box 3 than the lead lowermost end 76b.

[0092] As described above, the second hook 772 is formed to be located above the first hook 771. The second hook 772 is provided at the side end of the hook middle portion 77b in a direction perpendicular to the up-down direction (Z-axis direction). That is, the second hook 772 is provided at a side position relative to the hook middle portion 77b.

[0093] The second hook 772 is formed to be located above the first hook 771. Therefore, the pump lead wire 76 located between the lead wire lowermost end portion 76b and the second hook 772 is routed so as to extend in the up-down direction along the hook intermediate portion 77b.

[0094] The second hook 772 includes an inner wall portion 772a, a bottom wall portion 772b, an outer wall portion 772c, and a protrusion 772d. The inner wall portion 772a is a plate-shaped member. The inner wall portion 772a is a wall portion forming the side of the hook middle portion 77b. The inner wall portion 772a forms a right side wall portion 1e1 (see Figure 7) is disposed at a position opposite to the inner wall portion 772a. The inner wall portion 772a is formed to extend in the front-rear direction (Y-axis direction) and in the up-down direction (Z-axis direction) in the housing 1. The plate surface of the inner wall portion 772a is formed to face the left-right direction (X-axis direction).

[0095] The bottom wall portion 772b constitutes the bottom wall of the second hook 772. The bottom wall portion 772b is formed to extend from the lower end of the inner wall portion 772a in a direction opposite to the formation side of the first hook 771. The bottom wall portion 772b constitutes a wall extending in the front-rear direction (Y-axis direction) and in the left-right direction (X-axis direction) in the housing 1. The plate surface of the bottom wall portion 772b is formed to face the up-down direction (Z-axis direction).

[0096] The outer wall portion 772c is a plate-shaped member. The inner wall of the outer wall portion 772c is a wall opposite to the inner wall portion 772a in the left-right direction (X-axis direction). In addition, the outer wall of the outer wall portion 772c forms a right side wall portion 1e1 (see Figure 7 ). The outer wall portion 772c is a wall extending in the front-to-rear direction (Y-axis direction) and in the up-down direction (Z-axis direction) in the housing 1. The plate surface of the outer wall portion 772c is formed to face the left-right direction (X-axis direction). The outer wall portion 772c is formed to extend upward from the end of the bottom wall portion 772b on the opposite side to the inner wall portion 772a.

[0097] The protrusion 772d is formed to protrude from the inner wall portion 772a toward the outer wall portion 772c. The protrusion 772d is formed at a position opposite to the upper end of the outer wall portion 772c. The gap between the protrusion 772d and the outer wall portion 772c is formed to be smaller than the gap between the inner wall portion 772a and the outer wall portion 772c. When viewed in the front-back direction (Y-axis direction), the protrusion 772d is formed in a triangular shape. The inclined surface of the protrusion 772d formed in a triangular shape is formed to face upward.

[0098] The wire hook 77 is configured so that the pump wire 76 disposed between the outer wall portion 772c and the inner wall portion 772a is not easily dropped out by including the protrusion 772d on the second hook 772. In addition, when viewed in the front-back direction (Y-axis direction), the protrusion 772d is formed in a triangular shape, so that the pump wire 76 is easily inserted into the second hook 772, and the pump wire 76 is not easily dropped out from the second hook 772.

[0099] The wire clamp 78 is a component that supports the pump wire 76. The wire clamp 78 is a component on which the pump wire 76 is hooked and holds the pump wire 76. When the operator hooks the pump wire 76 on the wire clamp 78, the wire clamp 78 can hold the pump wire 76. The wire clamp 78 is attached to the pump fixing member 74, and is located above the second hook 772, and is located on the side closer to the electric box 3 than the second hook 772.

[0100] The wire clamp 78 is a member bent into a spiral shape, and the pump wire 76 is arranged in the space of the bent central portion. Figure 8 and Fig. 9 As shown, the wire clamp 78 is mounted on the pedestal base portion 74a of the pump fixing member 74. The wire clamp 78 supports the pump wire 76 at a position closer to the electric box 3 than the second hook 772 of the wire hook 77. The wire clamp 78 is provided at a position above the first hook 771.

[0101] (Detailed Structure of Water Level Measuring Device 8)

[0102] The water level measuring device 8 is a sensor for measuring the water level of condensed water. The water level measuring device 8 is, for example, a float switch. In addition, the water level measuring device 8 is not limited to a float switch type device, and other types of devices such as an ultrasonic reflection type device and an infrared reflection type device may also be used. In the embodiment, the water level measuring device 8 is described as a float switch type sensor.

[0103] like Figure 8 and Fig. 9 As shown, the water level measuring device 8 includes a switch body 81, a float 82, and a switch fixing portion 83. The switch body 81 is a main body of the water level measuring device 8, and has the float 82 at the lower end. The switch body 81 holds the float 82 so as to be movable in the vertical direction (Z-axis direction).

[0104] The float 82 is provided to extend downward from the switch body 81. The float 82 has buoyancy, contacts the surface of the condensed water accumulated in the drain pan 9, and moves in the up-down direction as the water level of the condensed water accumulated in the drain pan 9 changes. The water level measuring device 8 detects the water level of the drain pan 9 by measuring the up-down movement of the float 82.

[0105] The switch fixing portion 83 is provided with a switch body 81 and covers the outside of the switch body 81. The switch lead 84 is connected to the switch body 81 of the water level measuring device 8 and the electric box 3, and electrically connects the water level measuring device 8 and the electric box 3. The switch lead 84 is used to send the measurement result of the detected water level to the electric box 3.

[0106] (Wiring of Pump Lead 76)

[0107] The pump wire 76 is first fixed to the first hook 771 and the second hook 772 in sequence from the wire terminal 76a. Then, the pump wire 76 is fixed to the wire clamp 78 provided on the pump fixing member 74. Figure 5 As shown, the portion of the pump wire 76 after the wire clamp 78 passes through the partition hole 11 a and is fixed to the terminal of the electrical box 3 located at the rear of the housing 1.

[0108] As the height of the path of the pump wire 76, Figure 8 As shown, the first hook 771 is arranged below the lead terminal 76a, and the second hook 772 is arranged above the first hook 771. Therefore, the pump lead 76 is routed between the lead terminal 76a and the second hook 772 in a state bent into a U shape through the first hook 771.

[0109] In other words, the U-shape of the pump wire 76 and the wire bottom end 76b are formed by the second hook 772 and the first hook 771 disposed below the wire terminal 76a. Figure 5 and Figure 8 As shown, the wire clamp 78 is arranged above the second hook 772 , and the partition hole 11 a is formed so as to be located above the wire clamp 78 .

[0110] like Figure 5 and Figure 8 As shown, in the heat exchange chamber 1c, the pump lead 76 is routed so that the portion between the second hook 772 and the partition hole 11a extends in the front-rear direction (Y-axis direction). In addition, the pump lead 76 is routed so that the portion between the second hook 772 and the first hook 771 is wound from the right side of the lead hook 77 toward the front side and extends in the vertical direction along the hook middle portion 77b.

[0111] The pump lead 76 is routed so as to extend in the vertical direction between the first hook 771 and the lead terminal 76a. The lead lowermost end 76b of the pump lead 76 disposed on the first hook 771 is the lowermost portion of the pump lead 76 between the second hook 772 and the lead terminal 76a.

[0112] [Effects of air conditioners]

[0113] During the cooling operation of the air conditioner 100, the heat exchanger 6 is cooled. At this time, the heat exchanger chamber 1c of the air conditioner 100 where the heat exchanger 6 exists, that is, the space in front of the partition 11, is also cooled simultaneously with the heat exchanger 6. In particular, when the cooling operation of the air conditioner 100 starts, the warm air in the housing 1 is cooled, and condensation is generated on the drain pump 7, the water level measuring device 8, and the portion in front of the partition 11 of the inner surface of the housing 1, mainly the heat exchanger 6.

[0114] In an air conditioner without the wire hook 77, water droplets caused by condensation gather on the pump wire 76 in the drain pump 7, and the condensed water may flow along the pump wire 76 toward the wire terminal 76a or the electrical box 3. When the condensed water flows toward the wire terminal 76a, the wire terminal 76a may be deformed due to corrosion, and a normal electrical signal may not be transmitted to the drain pump 7.

[0115] The air conditioner 100 has a wire hook 77, which is arranged on the side of the pump body 71 and holds the position where the pump wire 76 is wired. The wire hook 77 fixes the pump wire 76 from the wire terminal 76a to the electric device box 3, and fixes the pump wire 76 from the lowermost portion to the upper side. The air conditioner 100 uses the wire hook 77 to fix the wiring path of the pump wire 76, thereby preventing condensed water from flowing along the pump wire 76 toward the wire terminal 76a. Therefore, even if condensed water adheres to the pump wire 76, the air conditioner 100 can suppress the condensed water from adhering to the wire terminal 76a along the pump wire 76.

[0116] The air conditioner 100 of the embodiment includes a wire hook 77 to prevent condensed water from flowing toward the wire terminal 76a along the pump wire 76. The wire hook 77 includes a first hook 771, which is located below the wire terminal 76a and is hooked and held by the pump wire 76. In addition, the wire hook 77 includes a second hook 772, which is located above the first hook 771 and is located closer to the side of the electric box 3 than the first hook 771 and is hooked and held by the pump wire 76.

[0117] The pump lead 76 is wired so as to extend in the up-down direction at a portion between the lead terminal 76a and the first hook 771. Therefore, the air conditioner 100 prevents condensed water from flowing along the pump lead 76 toward the lead terminal 76a, and even if condensed water adheres to the pump lead 76, it is possible to suppress the condensed water from adhering to the lead terminal 76a along the pump lead 76.

[0118] The pump lead 76 is bent in a U-shape and includes a lead lowermost end portion 76b which is the lowermost portion bent in the U-shape. The lead lowermost end portion 76b is disposed on the first hook 771 and is located at the lowermost portion of the pump lead 76 between the lead terminal 76a and the second hook 772. In the air conditioner 100, the first hook 771 is disposed below the lead terminal 76a, and the lead lowermost end portion 76b disposed on the first hook 771 is the lowermost portion of the pump lead 76.

[0119] In the air conditioner 100, even if condensed water is generated or transferred by the pump wire 76, the condensed water is collected by gravity at the wire lowermost end 76b formed by the first hook 771 of the wire hook 77. In the air conditioner 100, even if condensed water is generated or transferred by the pump wire 76, the condensed water does not flow toward the wire terminal 76a due to the wire hook 77, and the condensed water does not stay at the wire terminal 76a. The condensed water collected at the wire lowermost end 76b drips from the wire lowermost end 76b due to gravity soon, and is recovered by the drain pan 9 arranged below the drain pump 7. The first hook 771 of the wire hook 77 functions as a drain bend shape relative to the pump wire 76.

[0120] In addition, in the conventional wiring of the pump wire 76, there is a concern that the pump wire 76 may pass through an undesired location due to looseness or the like even after wiring, and the pump wire 76 may be damaged by contact with the edge of other components. Therefore, the air conditioner is required to fix the pump wire 76 without looseness to suppress damage to the pump wire 76 caused by contact with the edge of other components.

[0121] As described above, the wire hook 77 of the air conditioner 100 has a first hook 771, which is located below the wire terminal 76a and is hooked and held by the pump wire 76. In addition, the wire hook 77 has a second hook 772, which is located above the first hook 771 and is located closer to the side of the electric box 3 than the first hook 771, and is hooked and held by the pump wire 76.

[0122] The first hook 771 and the second hook 772 of the wire hook 77 in the air conditioner 100 can fix the pump wire 76 so that there is no slack in the path of the pump wire 76 from the wire hook 77 to the wire clamp 78. Therefore, the air conditioner 100 can suppress damage to the pump wire 76 caused by contact between the pump wire 76 and other components.

[0123] In addition, as described above, in the conventional wiring of the pump wire 76, there is a concern that the pump wire 76 may pass through an undesired location due to looseness or the like even after wiring, and the pump wire 76 may be damaged due to contact with the edge of other components. In order to solve this problem, the pump wire 76 is sometimes fixed by a strapping machine which is a consumable. However, when the drain pump 7 is replaced due to maintenance, the strapping machine needs to be cut off, and the pump wire 76 needs to be fixed again by another strapping machine after the drain pump 7 is replaced, which has the problem of complexity of the operation process and cost. It is desired that the air conditioner can easily attach and detach the pump wire 76 multiple times.

[0124] The wire hook 77 of the air conditioner 100 has a first hook 771, which is located below the wire terminal 76a and is hooked and held by the pump wire 76. In addition, the wire hook 77 has a second hook 772, which is located above the first hook 771 and is located closer to the side of the electric box 3 than the first hook 771, and is hooked and held by the pump wire 76.

[0125] The air conditioner 100 does not use consumables such as a tying machine, and fixes the pump wire 76 by hooking the pump wire 76 on the wire hook 77. Even when the operator removes the drain pump 7 for repair or the like and fixes it again, the operation can be completed by simply hooking the pump wire 76 again on the wire hook 77. Therefore, the air conditioner 100 can easily attach and detach the pump wire 76 multiple times.

[0126] The drain pump 7 has a wire clamp 78 for hooking and holding the pump wire 76. The wire clamp 78 is mounted on the pump fixing member 74 and is located above the second hook 772 and closer to the electric box 3 than the second hook 772.

[0127] The air conditioner 100 does not use consumables such as a tying machine, and fixes the pump wire 76 by hooking the pump wire 76 on the wire clamp 78. Even when the operator removes the drain pump 7 for repair or the like and fixes it again, the operation can be completed by simply hooking the pump wire 76 again on the wire clamp 78. Therefore, the air conditioner 100 can easily attach and detach the pump wire 76 multiple times.

[0128] In addition, the pump fixing member 74 is disposed between the pump body 71 and the pump and switch fixing member 70 as a base for the pump body 71, and the pump body 71 is installed in such a manner that the suction port 7a of the pump body 71 faces the lower side where the drain pan 9 is disposed. By using the pump fixing member 74 as a base for the pump body 71, the air conditioner 100 can make the suction port 7a of the pump body 71 close to the drain pan 9. In addition, by using the pump fixing member 74 as a base for the pump body 71, the air conditioner 100 can suppress the vibration of the pump body 71 from being transmitted to the casing 1.

[0129] Moreover, the wire hook 77 of the air conditioner 100 is attached to the pump fixing member 74 so as to be suspended from the pump fixing member 74. With this structure, the air conditioner 100 can arrange the first hook 771 below the wire terminal 76a of the pump body 71.
