[0010] Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Dimensions, materials, and other specific values ​​shown in these embodiments are merely examples for facilitating understanding of the invention and, unless otherwise specified, do not limit the present invention. In this specification and drawings, elements having substantially the same functions and configurations are designated by the same reference numerals to avoid redundant explanation, and elements not directly related to the present invention are not shown.

[0011] An overview of a cart 1 according to this embodiment will be described with reference to FIG.

[0012] FIG. 1 is a perspective view of a cart 1 according to this embodiment. The cart 1 according to this embodiment is a self-propelled four-wheel vehicle equipped with a power source such as an engine or motor (not shown). In the following drawings, the forward direction of the cart 1 is indicated as "front" and the backward direction is indicated as "rear." Furthermore, the left direction when facing the forward direction of the cart 1 is indicated as "left" and the right direction is indicated as "right." The left-right direction of the cart 1 corresponds to the width direction of the cart 1. Furthermore, the upward direction of the cart 1 is indicated as "up" and the downward direction is indicated as "down."

[0013] A transparent resin panel 2 is provided at the front of the cart 1. A steering wheel 3 is provided at the front left of the cart 1. The driver can change the traveling direction of the cart 1 by operating the steering wheel 3.

[0014] A front seat 4 and a rear seat 5 are provided behind the steering wheel 3 and extend in the width direction of the cart 1. The front seat 4 and the rear seat 5 are arranged spaced apart in the fore-and-aft direction of the cart 1. The front seat 4 and the rear seat 5 can each accommodate two or three passengers seated side by side in the width direction of the cart 1.

[0015] The cart 1 also includes a ceiling panel 6. The ceiling panel 6 extends from above the resin panel 2 to behind the rear seat 5 in the direction in which the cart 1 moves backward. The width of the ceiling panel 6 is slightly larger than the width of the front seat 4 and the rear seat 5. The ceiling panel 6 is located above the front seat 4 and the rear seat 5, and a passenger space for passengers to sit is secured below the ceiling panel 6.

[0016] Four fans 100 are provided on the ceiling surface 6a, which is the underside of the ceiling board 6. The four fans 100 blow air toward passengers seated in the front seat 4 and the rear seat 5, respectively. Two of the four fans 100 are positioned away from each other in the width direction of the cart 1, at positions shifted in the forward direction from directly above the front seat 4. In this example, one fan 100 is positioned directly above the steering wheel 3.

[0017] The remaining two fans 100 are arranged spaced apart from each other in the width direction of the cart 1, at positions shifted in the forward direction from directly above the rear seat 5. In this example, the two fans 100 are located between the front seat 4 and the rear seat 5.

[0018] The two front fans 100, together with a rod member (see rod member 8 in Figures 19, 20, and 22 described below), form one fan unit 200. The two rear fans 100, together with a rod member (see rod member 8 in Figures 19, 20, and 22 described below), also form one fan unit 200. Each fan unit 200 is attached to a frame 7 of the cart 1. A pair of frames 7 are provided on both the left and right sides of the cart 1, and extend in the front-to-rear direction of the cart 1. Each frame 7 extends from near the front end to near the rear end of the ceiling panel 6, near the ceiling surface 6a of the ceiling panel 6. Details of how the fan units 200 are attached to the frames 7 will be described later.

[0019] An overview of the fan 100 according to this embodiment will be described with reference to FIGS.

[0020] 2 is a perspective view of the blower 100 according to this embodiment. When the blower 100 is attached to the cart 1, the front of the blower 100 faces the direction in which the cart 1 moves backward, and the back of the blower 100 faces the direction in which the cart 1 moves forward. Therefore, the left side of the blower 100 as viewed from the front side corresponds to the left side of the cart 1, and the right side of the blower 100 as viewed from the front side corresponds to the right side of the cart 1.

[0021] The blower 100 includes a main body case 110 (main body). The main body case 110 includes a top surface F1, a front surface F2, a back surface F3, and a bottom surface F4. The top surface F1 extends in the width direction and the front-to-rear direction of the blower 100. When the blower 100 is attached to the cart 1, the width direction of the blower 100 coincides with the width direction of the cart 1. When the blower 100 is attached to the cart 1, the front-to-rear direction of the blower 100 coincides with the front-to-rear direction of the cart 1. When the blower 100 is attached to the cart 1, the height direction of the blower 100 coincides with the up-to-down direction of the cart 1. Hereinafter, the width direction of the blower 100 will be simply referred to as the width direction, the front-to-rear direction of the blower 100 will be simply referred to as the front-to-rear direction, and the height direction of the blower 100 will be simply referred to as the height direction.

[0022] The main body case 110 extends in the width direction. In other words, the width of the main body case 110 is longer than the length of the main body case 110 in the front-rear direction and the height of the main body case 110. The top surface F1 has a generally flat shape that extends longer in the width direction than in the front-rear direction. The front surface F2 is continuous with the rear edge of the top surface F1 and extends downward from the top surface F1. The back surface F3 is continuous with the front edge of the top surface F1 and extends downward from the top surface F1. Therefore, the back surface F3 and the front surface F2 face each other and are spaced apart from each other in the front-rear direction.

[0023] The rear surface F3 extends further downward than the front surface F2. The lower surface F4 continues from the lower end of the front surface F2 to the lower end of the rear surface F3. A lower surface opening 111 is formed in the lower surface F4. The lower surface opening 111 is an opening that penetrates the lower surface F4 and is formed over almost the entire surface of the lower surface F4. Therefore, the lower surface F4 is formed only near both ends in the width direction. The main body case 110 is formed by assembling two members that are divided in the front-rear direction.

[0024] The main body case 110 is surrounded on all four sides by a top surface F1, a front surface F2, a back surface F3, and a bottom surface F4. A battery 120 is detachably attached to the back surface F3 of the main body case 110. The attachment of the battery 120 to the main body case 110 will be described in detail later.

[0025] Two through holes 112 are provided in the main body case 110. Each through hole 112 passes through the main body case 110 in the left-right direction. One through hole 112 is located at the top of the rear part of the main body case 110, and the other through hole 112 is located at the top of the front part of the main body case 110. The through holes 112 are used to attach the blower 100 to the cart 1. Details of attaching the blower 100 to the cart 1 will be described later.

[0026] An intake port cover 130 is provided at each of the openings on both sides in the width direction of main body case 110. Each of the openings on both sides in the width direction of main body case 110 is covered by intake port cover 130. Air intake port cover 130 has an intake port frame 131 and a plurality of fins 132.

[0027] Air intake frame 131 forms the outer edge of air intake cover 130 and extends along the edge of the opening at the end in the width direction of main body case 110. Each fin 132 is attached to the inner periphery of air intake frame 131. The gaps between fins 132 correspond to air intakes 140. In this way, air intake 140 is surrounded by air intake frame 131 and opens to the side of main body case 110. Air outside main body case 110 is taken into main body case 110 through air intake 140.

[0028] An air vent cover 150 is provided at the bottom opening 111 of the main body case 110. The air vent cover 150 protrudes from the inside of the main body case 110 to the outside of the main body case 110 through the bottom opening 111. The air vent cover 150 has an air vent frame 151 and a plurality of fins 152.

[0029] Air outlet frame 151 extends in the width direction at the bottom of main body case 110. Fins 152 are attached to the inner periphery of air outlet frame 151. Gaps between fins 152 correspond to air outlets 160. In this manner, air outlet 160 is surrounded by air outlet frame 151. Air outlet 160 opens in a direction (second direction) intersecting the width direction (first direction), which is the extension direction of main body case 110. Air taken into main body case 110 through air intake 140 is expelled from air outlet 160 to the outside of main body case 110.

[0030] 3 is a cross-sectional view taken along the line A1-A1 in FIG. 2. As shown in FIG. 3, a motor case 170 is housed inside the main body case 110. The motor case 170 is a substantially rectangular box, and is fixed to the center of the main body case 110 in the width direction. The motor case 170 houses a pair of motors 171 inside. The pair of motors 171 are arranged symmetrically with respect to each other in the width direction. Motor shafts 171a of the motors 171 protrude outward in the width direction from the motor case 170.

[0031] A rotor 172 is attached to the motor shaft 171a of the motor 171. The rotor 172 is a cylindrical member. The rotor 172 has a plurality of blades 172a that extend in the width direction and are arranged with gaps maintained in the rotation direction. A partition plate 172b is provided near the center of the rotor 172 in the width direction. The partition plate 172b has a circular, thin plate shape, and the tip side of the motor shaft 171a is fixed to the center. Therefore, the rotor 172 is rotatably supported within the main body case 110 by the motor shaft 171a. The partition plate 172b is also located between the air intake 140 and the motor 171. This reduces the risk of rainwater that has entered the rotor 172 from the air intake 140 reaching the motor 171.

[0032] Air intake 140 of main body case 110 is located in the axial direction of rotor 172. In other words, air intake 140 opens in the direction of the rotation axis of rotor 172. When rotor 172 is rotated by driving motor 171, air is taken into rotor 172 through air intake 140. The air taken into rotor 172 passes between blades 172a and is sent out radially outward from rotor 172.

[0033] A pair of scroll cases 180 are housed inside the main body case 110. Each scroll case 180 is arranged on both the left and right sides of the motor case 170. The scroll cases 180 are generally cylindrical boxes extending in the width direction. Each rotating body 172 is housed in its corresponding scroll case 180. Specifically, the left rotating body 172 is housed in the left scroll case 180, and the right rotating body 172 is housed in the right scroll case 180.

[0034] The pair of scroll cases 180 are connected by the air outlet cover 150. In other words, the air outlet cover 150 connects the pair of scroll cases 180. The air outlet 160 formed in the air outlet cover 150 is provided radially outward of the rotor 172 and opens in a direction perpendicular to the rotational axis direction. As will be described later, air is drawn into the rotor 172, passes between the blades 172a, and is sent out radially outward of the rotor 172, where it is pressurized and accelerated within the scroll case 180 and then sent out from the air outlet 160.

[0035] 2, a switch button 173 is provided on the outside of motor case 170. Switch button 173 faces the front side of blower 100. A sensor 174 for detecting a passenger is provided below switch button 173. Sensor 174 faces the front side of blower 100, below the horizontal direction. Openings are provided in main body case 110 at positions corresponding to switch button 173 and sensor 174.

[0036] Therefore, with motor case 170 housed inside main body case 110, switch button 173 and sensor 174 are exposed to the outside of main body case 110. This makes it possible to operate switch button 173 from outside main body case 110. It also makes it possible for sensor 174 to detect a passenger.

[0037] The sensor 174 is not particularly limited in configuration as long as it can detect the presence or absence of a passenger within its detection range. The sensor 174 can be configured with, for example, an infrared sensor, an ultrasonic sensor, or a visible light sensor.

[0038] Fan 100 is equipped with a control device (not shown). The control device has an electronic circuit including a CPU, RAM, and ROM, and is connected to motor 171, switch button 173, and sensor 174. The control device is activated by operating switch button 173, and receives power supply from battery 120 based on a signal input from sensor 174 to drive (control) motor 171. The control device may change the value of the current passed through motor 171 by operating switch button 173, thereby switching the operating state of fan 100 between strong and weak.

[0039] An aperture member 175 is provided in the opening of the main body case 110 that exposes the sensor 174. The aperture member 175 is a member that defines the detection range of the sensor 174, and is detachably provided on the main body case 110. The distance from the sensor 174 to the occupant and the optimum detection range for the occupant vary depending on the size of the cart 1 to which the blower 100 is attached and the installation position of the blower 100. Making the aperture member 175 detachable allows the aperture member 175 to be attached according to the size of the cart 1 and the installation position of the blower 100, and the optimum detection range for the sensor 174 can be easily set.

[0040] A recess is formed in the widthwise center of the air outlet cover 150 to avoid the sensor 174. The recess in the air outlet cover 150 prevents the detection range of the sensor 174 from being obstructed.

[0041] Fig. 4 is a cross-sectional view taken along the line A2-A2 in Fig. 2. As shown in Fig. 4, a rotor 172 is rotatably housed in a scroll case 180. A scroll flow passage 181 is formed in the scroll case 180 and positioned radially outward from the rotor 172. Specifically, the scroll flow passage 181 is formed by a gap formed between the inner circumferential surface of the scroll case 180 and the rotor 172.

[0042] The scroll passage 181 is wound around the entire circumference in the rotational direction of the rotor 172. In Fig. 4, the rotor 172 rotates clockwise. The scroll passage 181 has a radial width, i.e., a passage width, that gradually increases toward the front side in the rotational direction of the rotor 172. An air outlet cover 150 is attached to the scroll case 180 so as to close an outlet corresponding to the downstream end of the scroll passage 181.

[0043] With the above configuration, when the rotor 172 rotates, air is drawn into the rotor 172 from the intake port 140 in the direction of the rotation axis. Then, due to the rotation of the rotor 172, air is sent out radially from the inside of the rotor 172 to the outside through the gaps in the blades 172a. The air sent out radially from the rotor 172 is pressurized and accelerated while flowing through the scroll flow path 181, and is sent out to the outside from the blower port 160.

[0044] Here, scroll case 180 and vent cover 150 function as movable bodies provided in main body case 110 so as to be rotatable about an axis that is aligned with the width direction (first direction), which is the extension direction of main body case 110. These movable bodies operate about an axis that is aligned with the rotation axis direction of rotating body 172. In other words, scroll case 180 and vent cover 150 are rotatably supported by main body case 110. Here, the rotation axes of scroll case 180 and vent cover 150 coincide with the rotation axis of rotating body 172. However, the rotation axes of scroll case 180 and vent cover 150 may be misaligned with the rotation axis of rotating body 172.

[0045] Blower 100 is provided with angle adjustment mechanism 190, which will be described later. Angle adjustment mechanism 190 makes it possible to adjust the angles of scroll case 180 and air outlet cover 150. Consequently, the angle of air outlet 160 becomes adjustable.

[0046] Fig. 5 is a cross-sectional view taken along the line A3-A3 in Fig. 2. As shown in Fig. 5, angle adjustment mechanism 190 includes an adjustment groove 191 and a stopper member 192. Adjustment groove 191 is provided in each scroll case 180. Adjustment groove 191 is provided on the outer side in the width direction of each scroll case 180, i.e., at the end opposite to the side on which motor case 170 is provided.

[0047] The adjustment grooves 191 are grooves recessed in the radial direction of the rotor 172, and multiple adjustment grooves 191 are provided spaced apart in the rotational direction of the rotor 172. Here, multiple adjustment grooves 191 are provided at equal intervals over a range of approximately 90 degrees around the rotation axis of the rotor 172. Furthermore, a stopper member 192 is provided in the main body case 110 at a position facing the adjustment grooves 191 in the radial direction of the rotor 172. More precisely, the stopper member 192 is provided so that its tip faces the adjustment groove 191 from the radial outside of the rotor 172.

[0048] A biasing member (not shown) made of a spring or the like is provided in main body case 110, and the biasing force of this biasing member acts on stopper member 192. Specifically, the biasing member applies a biasing force to stopper member 192 in a direction such that the tip of stopper member 192 approaches adjustment groove 191. Therefore, the biasing force of the biasing member causes the tip of stopper member 192 to enter adjustment groove 191. When the tip of stopper member 192 enters adjustment groove 191, movement of scroll case 180 and air vent cover 150 in the rotational direction is suppressed.

[0049] The width of adjustment groove 191 in the circumferential direction of rotor 172 increases radially outward. Therefore, when scroll case 180 and air vent cover 150 are rotated in the rotational direction with the tip of stopper member 192 inserted into adjustment groove 191, stopper member 192 is pushed out by the bottom surface of adjustment groove 191.

[0050] For example, in the state shown in Fig. 5, the tip of stopper member 192 is inserted into the lowest adjustment groove 191. In this state, suppose that scroll case 180 and air vent cover 150 are rotated counterclockwise. In this case, stopper member 192 is pushed to the left in the figure by the bottom surface of adjustment groove 191 against the biasing force of the biasing member. As a result, the tip of stopper member 192 comes into contact with the wall surface between the lowest adjustment groove 191 and the second lowest adjustment groove 191.

[0051] In this state, when scroll case 180 and vent cover 150 are further rotated counterclockwise, the tip of stopper member 192 enters adjustment groove 191, which is second from the bottom. In this way, by rotating scroll case 180 and vent cover 150, the direction and angle of vent 160 can be changed. Note that the biasing force of the biasing member is set so that stopper member 192 is not pushed out of adjustment groove 191 by the weight of scroll case 180 and vent cover 150 itself.

[0052] Fig. 6 is a side view showing a first state of blower 100. Fig. 7 is a side view showing a second state of blower 100. In the first state of blower 100, as shown in Fig. 6, air outlet 160 faces in a substantially horizontal direction. In the first state of blower 100, the facing direction of air outlet 160 is closest to the horizontal direction. In the first state of blower 100, only a portion (specifically, the lower portion) of air outlet frame 151 protrudes downward relative to main body case 110.

[0053] In contrast, the second state of blower 100 is a state in which blower port 160 faces vertically downward, as shown in Fig. 7. In the second state of blower 100, all parts of blower port frame 151 protrude downward relative to main body case 110. Here, in the second state of blower 100, blower port 160 is horizontal.

[0054] The scroll case 180 and the air outlet cover 150 are rotatable between a first state and a second state. For example, the rotation angle of the scroll case 180 and the air outlet cover 150 changes by approximately 70° between the first state and the second state. This makes it possible to blow air to the optimal position according to the physical characteristics and preferences of the occupant.

[0055] Here, when the scroll case 180 and the air vent cover 150 are supported by the main body case 110, at least a portion of the air vent cover 150 is exposed to the outside from the bottom opening 111 of the main body case 110, as shown in FIGS. 6 and 7. The air vent cover 150 protrudes from the surface of the main body case 110 in a direction perpendicular to the rotational axis direction of the rotating body 172. In other words, the air vent 160 is positioned so as to protrude from the surface of the main body case 110 in a direction perpendicular to the rotational axis direction. This allows the passenger to adjust the angle of the air vent 160 by gripping the air vent cover 150 (for example, the air vent frame 151).

[0056] It is possible to provide a knob that protrudes from the air outlet cover 150 and adjust the angle of the air outlet 160 by operating the knob, for example. However, if a knob is provided, it may be difficult for a passenger to notice the knob, and there is a risk that the passenger may hit their head against the knob and be injured when getting in or out of the vehicle. In addition, there is a possibility that the knob may be damaged in this case. On the other hand, in this embodiment, at least a portion of the air outlet frame 151 protrudes from the surface of the main body case 110, so that the passenger can easily grasp the position of the air outlet frame 151 and the risk of hitting their head is reduced.

[0057] As described above, the orientation of the air outlet cover 150, i.e., the air outlet 160, is maintained at a desired angle between the first state and the second state by the stopper member 192. Here, one angle adjustment mechanism 190 is provided for each scroll case 180. However, the angle adjustment mechanism 190 may be provided for only one of the scroll cases 180. Alternatively, one angle adjustment mechanism 190 may be provided near the center of the blower 100 in the width direction.

[0058] As described above, blower 100 of this embodiment is a sirocco fan. According to blower 100, intake port 140 and outlet port 160 face in directions that are approximately perpendicular to each other. For example, a blower that takes in air in the forward direction of cart 1 and blows air in the backward direction of cart 1 would be large in size in one direction, making it difficult to install in a cart 1 with significant installation space constraints. According to this embodiment, the size in one direction can be reduced, making it possible to achieve a blowing function that is comfortable for passengers even in a cart 1 with significant installation space constraints.

[0059] Further improvements made to the fan 100 of this embodiment will be described below in order with reference to FIGS. 8 to 22.

[0060] First, with reference to FIGS. 8 and 9, the ingenuity in the configuration around the intake port 140 will be described.

[0061] Fig. 8 is a perspective view showing the periphery of air intake port 140. As described above, air intake port covers 130 are provided on both the left and right sides of main body case 110. Although Fig. 8 shows the right air intake port cover 130, the configuration of the left air intake port cover 130 is similar to the configuration of the right air intake port cover 130.

[0062] As described above, the air intake 140 is surrounded by the air intake frame 131 of the air intake cover 130. Here, passengers of the cart 1 enter the front seat 4 or the rear seat 5 from the width direction of the cart 1. When the blower 100 is attached to the cart 1, the air intake frame 131 is located at the outermost part of the blower 100 in the width direction of the cart 1. Therefore, there is a risk that the head of a passenger entering the cart 1 may hit the air intake frame 131.

[0063] Therefore, in this embodiment, the air intake frame 131 is made of an elastic material. Examples of elastic materials include silicone. By making the air intake frame 131 of an elastic material, if the occupant's head were to collide with the air intake frame 131, the impact on the occupant's head can be reduced, thereby improving safety.

[0064] Furthermore, in this embodiment, the intake port frame 131 is provided with uneven portions 131a. In the example of Fig. 8, the uneven portions 131a are pleated and provided in the lower half of the intake port frame 131. More specifically, in the uneven portions 131a, protrusions and grooves extending in the direction of the rotation axis of the rotor 172 and in a direction perpendicular to the rotation axis direction are alternately arranged in the circumferential direction of the intake port frame 131. By providing the uneven portions 131a in the intake port frame 131, if the head of an occupant were to collide with the intake port frame 131, the impact on the head of the occupant can be more effectively reduced, thereby more effectively improving safety.

[0065] However, uneven portion 131a may have a shape other than pleats, and may be, for example, a lattice shape. Also, uneven portion 131a may be formed around the entire periphery of intake port frame 131. However, since the part of intake port frame 131 that is most likely to be hit by the occupant's head is the lower part of intake port frame 131, it is particularly necessary to provide uneven portion 131a in the lower half of intake port frame 131.

[0066] A net (not shown) is provided on the air intake cover 130. The net covers the surface defined by the inner periphery of the air intake frame 131 and is breathable. The provision of the net prevents foreign matter from entering the interior of the main body case 110 through the air intake 140. When a cover is provided on the air intake cover 130, the air intake cover 130 becomes particularly susceptible to dirt. Therefore, it is necessary to clean the air intake cover 130. Therefore, to make it easier to clean the air intake cover 130, the air intake frame 131 is detachable from the main body case 110. A through-hole 133 shown in FIG. 8 penetrates the air intake frame 131 and is provided for attaching and detaching the air intake frame 131 to and from the main body case 110, as described below.

[0067] FIG. 9 is a cross-sectional view showing the periphery of intake port 140. As shown in FIG. 9, intake port cover 130 is provided with locking member 134. When viewed from above, locking member 134 has a substantially L-shape. Meanwhile, main body case 110 is provided with locked portion 113. Locking portion 113 is provided at an end of main body case 110 in the width direction, extends in the up-down direction, and has a pillar shape. Locking member 134 is movable in the left-right direction.

[0068] When air intake frame 131 is attached to main body case 110, locking member 134 is biased outward in the width direction by a biasing member such as a spring (not shown), and is locked to locked portion 113, as shown by the solid line in Fig. 9. This makes it impossible to remove air intake frame 131 from main body case 110. On the other hand, by inserting a long, thin rod into through hole 133 and pushing locking member 134 inward in the width direction with the tip of the rod, locking member 134 will be released from locked portion 113, as shown by the two-dot chain line in Fig. 9. This makes it possible to remove air intake frame 131 from main body case 110.

[0069] As described above, provision of locking member 134 and locked portion 113 makes air intake frame 131 detachable from main body case 110. This facilitates cleaning of air intake cover 130. Furthermore, air intake frame 131 cannot be removed from main body case 110 unless a long, thin rod is inserted into through-hole 133. For example, by setting the diameter of through-hole 133 to a size that prevents the insertion of golf equipment (such as a tee), it is possible to prevent a passenger from accidentally removing air intake frame 131 from main body case 110. However, the mechanism for making air intake frame 131 detachable from main body case 110 is not limited to the example shown in FIG. 9.

[0070] Next, with reference to FIGS. 10 to 13, the ingenuity regarding the configuration around the air outlet 160 will be described.

[0071] 10 is a perspective view showing the periphery of the air outlet 160. As described above, the air outlet 160 is surrounded by the air outlet frame 151 of the air outlet cover 150. Here, a passenger of the cart 1 gets into the front seat 4 or the rear seat 5 from the width direction of the cart 1. When the blower 100 is attached to the cart 1, at least a part of the air outlet frame 151 protrudes outward beyond the main body case 110. Therefore, there is a risk that the head of a passenger getting into the cart 1 may hit the air outlet frame 151.

[0072] Therefore, in this embodiment, the air outlet frame 151 is made of an elastic material. Examples of elastic materials include silicon. By making the air outlet frame 151 of an elastic material, if the occupant's head were to collide with the air outlet frame 151, the impact on the occupant's head can be reduced, thereby improving safety.

[0073] More specifically, the air outlet frame 151 is formed from an elastic member over the entire circumferential area. As described above, depending on the rotation angle of the air outlet cover 150, all parts of the air outlet frame 151 protrude downward relative to the main body case 110. Therefore, there is a possibility that the occupant's head may collide with any part of the air outlet frame 151. Therefore, by forming the air outlet frame 151 from an elastic member over the entire circumferential area, if the occupant's head were to collide with the air outlet frame 151, the impact on the occupant's head can be appropriately reduced, thereby appropriately improving safety.

[0074] Furthermore, the length of the air outlet frame 151 in the opening direction (second direction) of the air outlet 160 becomes shorter at the widthwise ends of the air outlet frame 151 as it moves away from the widthwise center of the air outlet frame 151. For example, in the example of Fig. 10, the length of the air outlet frame 151 in the opening direction is constant at length L1 at the widthwise center of the air outlet frame 151. Meanwhile, at the widthwise ends of the air outlet frame 151, the length of the air outlet frame 151 in the opening direction gradually decreases from length L1 to length L2, which is shorter than length L1, as it moves outward in the width direction.

[0075] As described above, the air outlet frame 151 extends in the width direction (first direction). Therefore, if the head of a passenger collides with an end portion of the air outlet frame 151 in the width direction, the impact on the head of the passenger is likely to be large. Therefore, as described above, the length of the air outlet frame 151 in the opening direction becomes shorter at the end portions of the air outlet frame 151 in the width direction as it gets farther away from the center of the air outlet frame 151 in the width direction. This effectively reduces the impact on the head of the passenger when the head collides with an end portion of the air outlet frame 151 in the width direction, thereby more effectively improving safety.

[0076] Fig. 11 is a cross-sectional view showing the periphery of the air outlet 160. The fins 152 of the air outlet cover 150 include a plurality of first fins 152a extending in the width direction shown in Fig. 10 and a plurality of second fins 152b extending in a direction intersecting the width direction shown in Fig. 11.

[0077] The first fins 152a are fixed to the air outlet frame 151 and are arranged across the entire area of ​​the air outlet cover 150. On the other hand, the second fins 152b are not arranged in the center of the width of the air outlet cover 150, but are arranged on the left and right sides. While Fig. 11 shows the internal configuration of the right side of the air outlet cover 150, the internal configuration of the left side of the air outlet cover 150 is similar to the internal configuration of the right side of the air outlet cover 150.

[0078] As shown in Fig. 11, a plurality of second fins 152b are arranged at intervals in the width direction on the outer side of the air outlet cover 150 in the width direction. In the example of Fig. 11, three second fins 152b are arranged, but the number of second fins 152b may be other than three. Each second fin 152b has a flat plate shape extending on a plane intersecting the width direction. A knob 153 that is operated by a passenger is provided at the rear end of one of the second fins 152b (the central second fin 152b in Fig. 11).

[0079] The front ends of the second fins 152b are connected by a connecting member 154, allowing the second fins 152b to move in unison. Each second fin 152b is provided rotatable about a rotation shaft 155 that passes near the center of the second fin 152b in the front-to-rear direction, is perpendicular to the width direction, and is parallel to the air outlet 160. Therefore, as shown by the solid arrow in FIG. 11 , when a passenger moves the knob 153 left or right, each second fin 152b rotates about the rotation shaft 155, changing the orientation of each second fin 152b left or right. This changes the direction of air blown from the air outlet 160 left or right. Therefore, for example, when three passengers are riding in the rear seat 5 of the cart 1, the air from the air outlet 160 can reach the passenger sitting in the center.

[0080] From the viewpoint of increasing the strength of the airflow from air outlet 160, it is preferable that the front end of second fin 152b be tapered and as thin as possible. From the same viewpoint, it is preferable that the front end of first fin 152a also be tapered and as thin as possible.

[0081] Fig. 12 is a front view showing blower 100 in a first state. Fig. 13 is a front view showing blower 100 in a second state. As described above, in the first state of blower 100, the direction in which air outlet 160 faces is closest to the horizontal direction. On the other hand, in the second state of blower 100, as shown in Fig. 7, air outlet 160 faces vertically downward.

[0082] As shown in FIG. 13, main body case 110 is provided with cable terminal 114 and cable terminal cover 115. Cable terminal 114 is a terminal to which a cable is connected. When changing the setting information of fan 100, a computer is connected to cable terminal 114 via a cable. Cable terminal cover 115 is a cover that covers cable terminal 114. When cable terminal 114 is not in use, as shown in FIG. 13, cable terminal 114 is covered by cable terminal cover 115. On the other hand, when cable terminal 114 is used (specifically, when changing the setting information of fan 100), cable terminal cover 115 is opened or removed, and cable terminal 114 is exposed.

[0083] As shown in Fig. 12, in the first state of blower 100, cable terminal cover 115 is covered by air outlet cover 150, which is a movable body. On the other hand, as shown in Fig. 13, in the second state of blower 100, cable terminal cover 115 is exposed and not covered by air outlet cover 150, which is a movable body. In this way, cable terminal cover 115 is exposed when the rotation angle of air outlet cover 150 is within a predetermined range, and is covered by air outlet cover 150 when the rotation angle of air outlet cover 150 is outside the predetermined range.

[0084] The predetermined range is, for example, a range that includes the rotation angle of blower 100 in the second state. In other words, when blower 100 transitions from the first state to the second state, if the rotation angle of air outlet cover 150 exceeds a predetermined angle, cable terminal cover 115 is exposed. This prevents a passenger from accidentally opening or removing cable terminal cover 115 and exposing cable terminal 114.

[0085] Note that the setting information of blower 100 that can be changed using cable terminal 114 is not particularly limited. For example, in a case where control is performed to stop motor 171 when a predetermined time has elapsed since sensor 174 no longer detected a passenger, the setting information may be information about the predetermined time. Also, in a case where control is performed to stop motor 171 by determining that an error has occurred if the rotation speed of motor 171 has not reached a predetermined rotation speed when a predetermined time has elapsed since motor 171 was started, the setting information may be information about the predetermined time or the predetermined rotation speed.

[0086] Next, with reference to FIGS. 14 to 18, the following describes the ingenuity involved in attaching the battery 120 to the main body case 110. FIG.

[0087] Fig. 14 is a perspective view showing a state in which the battery 120 is attached to the main body case 110. Fig. 15 is a perspective view showing a state in which the battery 120 is not attached to the main body case 110.

[0088] 14, the battery 120 is attached to the rear surface F3 of the main body case 110. However, the battery 120 may be attached to a surface other than the rear surface F3 as long as it is attached to the surface of the main body case 110. Note that, as shown in FIG. 14, the length of the battery 120 in the left-right direction (i.e., width direction) is shorter than the length of the main body case 110 in the left-right direction, the length of the battery 120 in the front-rear direction is shorter than the length of the main body case 110 in the front-rear direction, and the length of the battery 120 in the up-down direction (i.e., height direction) is shorter than the length of the main body case 110 in the up-down direction.

[0089] The battery 120 is attached to the rear surface F3 of the main body case 110 in an attachment direction D1 (see FIG. 15) along the rear surface F3. In the example of FIG. 15, the attachment direction D1 is to the right. However, the attachment direction D1 may be other than to the right.

[0090] As shown in Figure 15, a main body terminal 116 is provided on the rear surface F3 of the main body case 110. The main body terminal 116 protrudes from the rear surface F3. Specifically, the main body terminal 116 protrudes in a direction perpendicular to the rear surface F3. The main body terminal 116 extends in the vertical direction. When the battery 120 is attached to the main body case 110, the main body terminal 116 is connected to a battery terminal (see battery terminal 121 in Figures 16 and 17 described later) which is a terminal of the battery 120.

[0091] Furthermore, a main body terminal cover 117 is provided on the rear face F3 of the main body case 110. The main body terminal cover 117 covers the tips of the main body terminals 116 when the battery 120 is not attached to the main body case 110. As will be described later, the main body terminal cover 117 is movable in a direction along the rear face F3, and moves when the battery 120 is attached to the main body case 110. The main body terminal cover 117 will be described in detail later.

[0092] A pair of stoppers 118 are provided on the rear surface F3 of the main body case 110. The stoppers 118 are provided above and below the main body terminals 116. Each stopper 118 protrudes from the rear surface F3. Specifically, each stopper 118 protrudes in a direction perpendicular to the rear surface F3. The left end surface of each stopper 118 is located to the left of the left end surface of the main body terminals 116. When the battery 120 is attached to the rear surface F3 of the main body case 110 in the attachment direction D1, there is a possibility that the surface of the battery 120 will collide with the main body terminals 116 from the left side. In this case, the provision of the stoppers 118 allows the surface of the battery 120 to collide with the stoppers 118 before colliding with the main body terminals 116. This prevents damage to the main body terminals 116.

[0093] The main body terminal cover 117 will be described in detail below with reference to FIGS.

[0094] 16 is a cross-sectional view showing the periphery of the main body terminal cover 117 immediately before the battery 120 is attached to the main body case 110. As described above, the battery 120 is provided with the battery terminal 121. The battery 120 has a substantially rectangular parallelepiped shape. When the battery 120 is attached to the main body case 110, the battery terminal 121 is provided on the rear surface of the battery 120.

[0095] As shown in FIG. 16, the main body terminal cover 117 has a first extending portion 117a, a second extending portion 117b, a third extending portion 117c, and a fourth extending portion 117d.

[0096] The first extending portion 117a extends on a plane perpendicular to the front-rear direction and has a flat plate shape. The first extending portion 117a is located outside the main body case 110.

[0097] The second extending portion 117b extends on a plane perpendicular to the left-right direction and has a flat plate shape. The second extending portion 117b extends rearward from the right end of the first extending portion 117a. The second extending portion 117b extends from the outside to the inside of the main body case 110.

[0098] The third extending portion 117c extends on a plane perpendicular to the front-rear direction and has a flat plate shape. The third extending portion 117c extends rightward from the rear end of the second extending portion 117b. The third extending portion 117c is located inside the main body case 110.

[0099] The fourth extension portion 117d extends on a plane perpendicular to the left-right direction and has a flat plate shape. The fourth extension portion 117d extends rearward from near the center of the first extension portion 117a in the left-right direction. The fourth extension portion 117d is located outside the main body case 110. The length of the fourth extension portion 117d in the front-rear direction is shorter than the length of the second extension portion 117b in the front-rear direction.

[0100] 16, when the battery 120 is not attached to the main body case 110, the first extension portion 117a of the main body terminal cover 117 is located forward of the tip of the main body terminal 116. That is, in this state, the tip of the main body terminal 116 is covered by the first extension portion 117a of the main body terminal cover 117. Specifically, the tip of the main body terminal 116 is covered by a portion of the first extension portion 117a that is to the left of the fourth extension portion 117d.

[0101] Here, the terminal cover 117 is biased in a biasing direction D2, which is opposite to the mounting direction D1, by a biasing member such as a spring (not shown). In the example of FIG. 16, the biasing direction D2 is to the left. The terminal cover 117 is movable left and right. In the state of FIG. 16, no external force is applied to the terminal cover 117. Therefore, in the state of FIG. 16, the terminal cover 117 is positioned at the leftmost position within its movable range. At this time, as shown in FIG. 16, the abutment surface 117e, which is the left surface of the fourth extension portion 117d of the terminal cover 117, abuts against the terminals 116 in the biasing direction D2.

[0102] 16, although no external force is being applied to the main body terminal cover 117, the step 122 on the rear surface of the battery 120 is in contact with the left end of the first extension 117a of the main body terminal cover 117. When the battery 120 moves in the attachment direction D1 from this state, the main body terminal cover 117 is pushed by the step 122 of the battery 120 and moves to the right.

[0103] Fig. 17 is a cross-sectional view showing the periphery of the main body terminal cover 117 after the battery 120 has been attached to the main body case 110. The state in Fig. 17 is a state in which the battery 120 has moved in the attachment direction D1 from the state in Fig. 16, and the battery terminals 121 are connected to the main body terminals 116. As described above, when the battery 120 moves in the attachment direction D1 from the state in Fig. 16, the main body terminal cover 117 is pushed by the stepped portion 122 of the battery 120 and moves to the right.

[0104] 17, main body terminal cover 117 is positioned at the rightmost position within its movable range. As shown in Fig. 17, when battery 120 is attached to main body case 110, first extension portion 117a of main body terminal cover 117 does not face the front-rear direction to the tips of main body terminals 116. In other words, in this state, the tips of main body terminals 116 are not covered by first extension portion 117a of main body terminal cover 117 and are exposed.

[0105] As described above, main body terminal cover 117 covers the tips of main body terminals 116 when battery 120 is not attached to main body case 110, and moves in attachment direction D1 to a position where the tips of main body terminals 116 are exposed when battery 120 is attached to main body case 110. As a result, main body terminal cover 117 prevents the surface of battery 120 from colliding with main body terminals 116 when battery 120 is attached to main body case 110. Therefore, damage to main body terminals 116 can be prevented.

[0106] 18 is a cross-sectional view showing a state in which the main terminal 116 is deformed. The main terminal 116 may be deformed by an unexpected external force. For example, as shown in FIG. 18, the main terminal 116 may be deformed so that the tip of the main terminal 116 falls in the mounting direction D1 of the battery 120. In such a case, the abutment surface 117e of the fourth extension portion 117d of the main terminal cover 117 can correct the falling deformation of the main terminal 116.

[0107] As described above, when the battery 120 is not attached to the main body case 110, the abutment surface 117e of the main body terminal cover 117 abuts against the main body terminals 116 in the biasing direction D2. Therefore, by pressing the main body terminal cover 117 from the state shown in Figure 18 in the biasing direction D2 against the main body terminals 116, the main body terminals 116 are pressed in the biasing direction D2 by the abutment surface 117e, and the tilted deformation of the main body terminals 116 is corrected.

[0108] Next, with reference to FIGS. 19 to 22, the ingenuity in attaching the fan unit 200 to the frame 7 will be described.

[0109] FIG. 19 is an exploded perspective view showing the portion of the fan unit 200 attached to the frame 7. FIG. 20 is a perspective view showing the portion of the fan unit 200 attached to the frame 7. One fan unit 200 includes two fans 100 and two rod members 8. The rod members 8 are, for example, hollow pipes and have a cylindrical shape. For example, the length of the rod members 8 is adjustable.

[0110] The two fans 100 included in one fan unit 200 are arranged with a gap between them in the left-right direction. Note that FIGS. 19 and 20 show only one of the two fans 100 included in one fan unit 200. As described above, the main body case 110 of the fan 100 has through holes 112 formed in two locations, one in the front and one in the back. The two rod members 8 included in one fan unit 200 are arranged with a gap between them in the front-to-back direction. The front rod member 8 is inserted through the front through hole 112 of each fan 100, and the rear rod member 8 is inserted through the rear through hole 112 of each fan 100. In this way, the two fans 100 are attached to the two rod members 8, and the two fans 100 and the two rod members 8 form an integrated unit.

[0111] Both ends of each rod member 8 are provided with a mechanism for attaching the fan unit 200 to the frame 7 of the cart 1. Such a mechanism will be described below with reference to Figures 19 and 20.

[0112] As shown in Fig. 19, a first bracket 9 and a second bracket 10 are provided at the end of the rod member 8. The first bracket 9 is fixed to the end of the rod member 8. The second bracket 10 is detachable from the first bracket 9. As shown in Fig. 20, the frame 7 is sandwiched between the first bracket 9 and the second bracket 10, thereby attaching the fan unit 200 to the frame 7.

[0113] As shown in FIG. 19, the first bracket 9 includes a cylindrical portion 9a, a first extending portion 9b, a second extending portion 9c, and a third extending portion 9d.

[0114] The cylindrical portion 9a has, for example, a rectangular cylindrical shape. The cylindrical portion 9a is fitted to the outer periphery of the end of the rod member 8 and fixed by screw fastening. The cylindrical portion 9a is arranged coaxially with the rod member 8. In other words, the axial direction of the cylindrical portion 9a coincides with the extension direction of the rod member 8.

[0115] The first extending portion 9b has a rectangular flat plate shape and extends on a plane perpendicular to the axial direction of the tubular portion 9a. The first extending portion 9b is connected to the end of the tubular portion 9a and covers the opening at the end of the tubular portion 9a. The first extending portion 9b is provided with a plurality of mating portions 9e. In the example of FIG. 19, the mating portions 9e are through holes. However, the mating portions 9e may also be grooves or depressions. The multiple mating portions 9e are arranged at intervals in the height direction (i.e., the up-and-down direction) of the fan 100.

[0116] The second extending portion 9c has a rectangular flat plate shape and extends on a plane parallel to the axial direction of the cylindrical portion 9a. The second extending portion 9c extends from the outer peripheral edge of the first extending portion 9b in a direction away from the cylindrical portion 9a. A through-hole 9f is provided in the second extending portion 9c.

[0117] The third extending portion 9d has a rectangular flat plate shape and extends on a plane parallel to the second extending portion 9c. The third extending portion 9d is continuous with the second extending portion 9c via a step and extends in a direction away from the tubular portion 9a.

[0118] As shown in FIG. 19, the second bracket 10 includes a first extending portion 10a, a second extending portion 10b, and a third extending portion 10c.

[0119] The first extension portion 10a has a rectangular flat plate shape. When the second bracket 10 is attached to the first bracket 9, the first extension portion 10a extends on a plane parallel to the second extension portion 9c and the third extension portion 9d of the first bracket 9. The first extension portion 10a is provided with a mating portion 10d that mates with the mated portion 9e of the first bracket 9. The mating portion 10d is a protrusion that protrudes from the outer periphery of the first extension portion 10a. The first extension portion 10a is also provided with a through-hole 10e that penetrates the first extension portion 10a.

[0120] The second extending portion 10b has a rectangular flat plate shape and extends on a plane parallel to the first extending portion 10a. The second extending portion 10b is continuous with the first extending portion 10a via a step and extends in a direction away from the mating portion 10d.

[0121] The third extension portion 10c has a rectangular flat plate shape and extends from the edge of the second extension portion 10b opposite to the first extension portion 10a in a direction perpendicular to the second extension portion 10b and in a direction approaching the first extension portion 10a. The third extension portion 10c is parallel to the step plane between the first extension portion 10a and the second extension portion 10b.

[0122] As shown in FIG. 20 , the frame 7 is sandwiched between the third extension portion 9d of the first bracket 9 and the second extension portion 10b of the second bracket 10 in the vertical direction, thereby attaching the fan unit 200 to the frame 7. When attaching the second bracket 10 to the first bracket 9, the mating portion 10d of the second bracket 10 is mated with one of the mating portions 9e of the first bracket 9. In the example shown in FIG. 20 , the mating portion 10d is mated with the uppermost mating portion 9e. Then, bolts are inserted into the through holes 9f of the first bracket 9 and the through holes 10e of the second bracket 10, and the first bracket 9 and the second bracket 10 are fastened together in the vertical direction, thereby sandwiching the frame 7 between the first bracket 9 and the second bracket 10. At this time, the third extension portion 10c of the second bracket 10 prevents the frame 7 from falling off.

[0123] As described above, the blower unit 200 includes a plurality of fitted portions 9e provided at the end of the rod member 8, the second extending portion 9c and the third extending portion 9d corresponding to the protrusions protruding from the end of the rod member 8 in the extension direction of the rod member 8, and the second bracket 10 that is fitted to one of the plurality of fitted portions 9e and corresponds to a clamping member that clamps the frame 7 of the cart 1 together with the protrusions. This allows the vertical distance between the first bracket 9 and the second bracket 10 to be changed by changing the fitted portion 9e to which the second bracket 10 (specifically, the fitting portion 10d) is fitted. Therefore, the blower unit 200 can be appropriately attached to the frame 7 in accordance with the dimensions of the frame 7.

[0124] Furthermore, as described above, by making the length of the rod member 8 adjustable, the fan unit 200 can be appropriately attached to the frame 7 in accordance with the gap between the left and right frames 7.

[0125] In the above, an example has been described in which the first bracket 9 and the rod member 8 are separate bodies, but all or any part of the first bracket 9 may be formed integrally with the rod member 8.

[0126] 21 is a cross-sectional view of the cart 1 as viewed from the left side. As described above, in this embodiment, the frame 7 is sandwiched between the first bracket 9 and the second bracket 10, thereby attaching the fan unit 200 to the frame 7. Therefore, by changing the position of the frame 7 that is sandwiched between the first bracket 9 and the second bracket 10, the position of the fan unit 200 in the front-to-rear direction can be easily changed.

[0127] 21, from the viewpoint of increasing the space for a passenger sitting in front seat 4 and preventing the passenger's head from hitting fan 100, it is preferable that front fan unit 200 be located as far forward as possible. For example, it is preferable that front fan unit 200 be located as far forward as possible to avoid interference with the mounting member for the navigation device provided on the upper part of the front side of plastic panel 2 of cart 1. However, it is preferable that the gap between battery 120 and the mounting member for the navigation device be a distance (e.g., 20 mm) or more that allows a person's hand to reach in to attach or detach battery 120.

[0128] Here, the gap L3 between the top surface F1 of the main body case 110 and the ceiling surface 6a of the cart 1 is less than the diameter of a golf ball. Specifically, the diameter of a golf ball is 42.67 mm. By reducing the gap L3 in this manner, the position of the blower 100 on the cart 1 can be set as high as possible. This can prevent the passenger's head from colliding with the blower 100, thereby improving safety. Furthermore, by reducing the gap L3, golf equipment such as a golf ball or a smartphone can be inserted into the gap L3, preventing these items from falling. This further improves safety.

[0129] Furthermore, when battery 120 is attached to main body case 110, bottom surface F6 of battery 120 is located higher than bottom surface F5 of main body case 110. This increases the space for the occupant and prevents the occupant's head from hitting blower 100, compared to when bottom surface F6 of battery 120 is flush with bottom surface F5 of main body case 110 or located lower than bottom surface F5 of main body case 110, thereby improving safety.

[0130] FIG. 22 is a cross-sectional view of the cart 1 as viewed from the rear. As described above, in the fan unit 200, each fan 100 is attached to the rod 8 with the rod 8 inserted through the through-hole 112. For example, each fan 100 is attached to the rod 8 by screw fastening. Therefore, the attachment position of the fan 100 to the rod 8 is adjustable. Specifically, as shown by the thick arrow in FIG. 22, the position of each fan 100 is adjustable relative to the cart 1 in the extension direction of the rod 8. In other words, the position of the main body case 110 of each fan 100 is adjustable relative to the cart 1 in a direction perpendicular to the side surface (left or right end surface) of the main body case 110 where the air intake 140 opens.

[0131] As described above, the position of blower 100 can be adjusted in the extending direction of rod member 8, so that the left-right position of blower 100 can be brought closer to the left-right center of cart 1. This prevents the head of a passenger from colliding with blower 100, thereby improving safety.

[0132] While the preferred embodiments of the present invention have been described above with reference to the accompanying drawings, it goes without saying that the present invention is not limited to these embodiments. It is clear that those skilled in the art can conceive of various modifications and alterations within the scope of the claims, and it is understood that these modifications and alterations also fall within the technical scope of the present invention.

[0133] For example, in the above description, the cart 1 is a golf cart, but the use of the cart 1 is not limited to this.

[0134] Furthermore, for example, in the above example, a plurality of fans 100 are unitized and the fan unit 200 is attached to the frame 7, but the method of attaching the fans 100 to the cart 1 is not limited to this. For example, each fan 100 may be attached to the cart 1 individually.

[0135] Furthermore, for example, in the above description, the blower 100 is a sirocco fan, but the configuration of the blower 100 is not limited to this.

[0136] Furthermore, for example, although sensor 174 for detecting a passenger is provided in the above description, sensor 174 is not an essential component. However, by automatically driving blower 100 when a passenger is detected by sensor 174 and stopping the driving of blower 100 when a passenger is no longer detected, it is possible to reduce unnecessary power consumption.

[0137] In the above description, for example, the fan 100 is provided with the battery 120. However, the battery 120 is not essential. For example, the fan 100 may be supplied with power from a power source provided in the cart 1.

[0138] Furthermore, for example, in the above example, when the blower 100 is attached to the cart 1, it is desirable that the intake port 140 does not face the ceiling surface 6a of the cart 1 in a side view of the cart 1. Alternatively, when the blower 100 is attached to the cart 1, it is desirable that the rotor 172 or the motor shaft 171a of the motor 171 does not face the ceiling surface 6a of the cart 1 in a side view of the cart 1. By doing so, the amount of intake air is ensured and a decrease in the blowing function is suppressed.

[0139] 8 and 9, the above describes the ingenuity regarding the configuration around the intake port 140. However, all or any part of the ingenuity regarding the configuration around the intake port 140 described above may not be implemented.

[0140] 10 to 13, the above has described the ingenuity regarding the configuration around the air outlet 160. However, all or any part of the ingenuity regarding the configuration around the air outlet 160 described above may not be implemented.

[0141] 14 to 18, the above has described the ingenious features relating to the attachment of battery 120 to main body case 110. However, all or any part of the ingenious features relating to the attachment of battery 120 to main body case 110 described above may not be implemented.

[0142] 19 to 22, the above has described the ingenious features relating to the attachment of fan unit 200 to frame 7. However, all or any part of the ingenious features relating to the attachment of fan unit 200 to frame 7 described above may not be implemented. [Explanation of symbols]
