Description

  The present invention relates to an elbow with an air-conditioning function that is particularly effective when applied to an object that requires air-conditioning according to the work environment of a worker, such as an office chair.

  In order to realize individual air conditioning for a person seated in a chair, various types of structures have been proposed in the past for sucking air from a seat or a backrest or blowing it out. These are for preventing heat from accumulating on the surface to which the seated person's body is in close contact, but the structure shown in Patent Document 1 is further provided with a structure for positively blowing air to the seated person's body. Proposed.

  This is a chair having a function of blowing air to a seated user, and a seat portion having a first air suction portion for sucking air on the upper surface or a second portion for sucking air on the front surface. A backrest portion having an air suction portion, an air outlet for ejecting air toward the user, and air sucked from the first air suction portion or the second air suction portion.

JP 2006-15023 A

  In this way, such a chair sucks the air on the seating surface and the backrest surface from the common air blowing means via the first air suction portion and the second air suction portion, and this is an air outlet provided on the elbow. It uses a structure that feeds into It can also be said that the cost of parts and the power efficiency are improved by providing a motor or the like at one place. However, when considering the flow resistance and the load on the air blowing means, it is considered that there is still room for generating an air flow more efficiently.

  For elbows in particular, a complicated internal flow path must be created in the armrest struts, etc. When applying to a movable elbow that changes the position and posture of the elbow relative to the seat, the pipe is further routed to the outside. It is inevitable that it will not look good, and it will also act as an operating resistance by pulling the pipe when the movable elbow operates.

  Therefore, it is the blowout from the elbow that directly affects the temperature of the sensation. Even if this is achieved, the environment and position where the chair is placed, the usage status of the work, etc. Individual adjustments according to individual differences and physical condition are possible. Therefore, if the air conditioning function can be completed at least at the elbow, instead of flowing air between the seat and the backrest, the air conditioning efficiency can be improved and it can be easily applied to the movable elbow, It is considered that a normal chair can be changed to a chair with an air-conditioning function simply by replacing the elbow.

  An object of the present invention is to newly realize such an elbow with an air conditioning function.

  In order to achieve this object, the present invention takes the following measures.

That is, the elbow with an air-conditioning function of the present invention is formed between a blowout port that opens in a part of the elbow body, a suction port that opens in another part of the elbow body, and the blowout port and the suction port. The elbow part air-conditioning mechanism is configured by an internal flow path that is provided in the internal flow path and a blower that receives power supply and sucks air from the suction port and blows out from the blow-out port. The elbow body is provided with operation means for receiving an operation for switching the state.
In this way, when the elbow air conditioning mechanism is provided directly on the elbow to individually generate the air flow, it is sufficient to ensure the necessary minimum flow path length, and the flow path resistance becomes a large load on the blowing means. By avoiding this, it is possible to efficiently generate an air flow with a simple blower. Moreover, the elbow itself is equipped with an air-conditioning mechanism. An appropriate air-conditioning environment according to physical condition etc. can be realized. In addition, since the air conditioning function is completed only at the elbow, it is not necessary to expose the pipe to the outside or form a complicated flow path inside, and the appearance of the applied chair or the like can be greatly improved. .

  In order to increase the efficiency of the built-in stool and air blowing, a blower and a wind direction adjusting unit that makes the air blowing direction from the blower variable are incorporated as a unit between the suction port and the blowout port of the elbow air conditioning mechanism. It is effective to leave

  In order to ensure the flexibility of the wind direction while ensuring such a function, the wind direction adjustment unit is provided so as to be able to swing at the position connecting the outlet and the outlet of the fan constituting the blower. It is desirable to form an internal flow path.

  In order to properly complete the elbow part air-conditioning mechanism in the elbow pad part, the elbow body includes a support part and an elbow pad part that can move relative to the support part, and at least the outlet and the suction port. It is effective to provide the mouth, the internal flow path, and the blower at the elbow rest.

  In order to suppress the flow path resistance of the elbow part air-conditioning mechanism as small as possible in the elbow pad part, the elbow body includes an elbow pad part and a support part that supports the elbow pad part, and at least the internal flow path and the A blower is provided in the elbow rest, the outlet is opened on the upper surface of the elbow rest, and the suction opening is opened on the lower surface of the elbow rest facing the blowout so as not to block the suction opening. It is preferable that the elbow rest part is supported by the support part.

  In order to appropriately attach the elbow to a chair or the like, it is effective that the elbow body further includes a battery accommodating portion for detachably incorporating a rechargeable battery.

  Since the elbow with air-conditioning function of the present invention has the above-described configuration, the air-conditioning function can be realized only by the elbow, thereby minimizing the flow path length and using a simple blower or the like. It is possible to achieve a high-efficiency air-conditioning function without the need for pipes that connect to the outside, and it is possible to effectively improve the appearance of applied chairs, etc. It is possible to easily change the specifications of a normal chair or the like to a chair with an air-conditioning function simply by changing the part, and it can be easy to use.

Even when placed at each position, the direction of blowing can be changed freely, so the seated person can get a cool feeling by sending wind directly to the desired part such as the face, chest, lower abdomen, thigh, etc. It is.

  And in this embodiment, the operation means 7 which put together the switching operation function with respect to the said seat part air-conditioning mechanism 5 and the switching operation function with respect to the elbow part air-conditioning mechanism 6 is provided in the elbow 4 as shown in FIG. According to the input operation situation, the power supply state for the seat air conditioning mechanism 5 and the elbow air conditioning mechanism 6 is switched through the switching circuit 8 shown in FIG.

  As shown in FIG. 7, the operating means 7 is a part of the elbow 4 that can be operated by the seated person in the sitting position, specifically in the vicinity of the base 41a of the right elbow frame 41 as viewed from the seated person in this embodiment. A seat air-conditioning switch 71 that is attached to a box 70 provided at a position where it can be used with the hand resting on the elbow rest 42, and that accepts an operation for switching on / off the power supply to the seat air-conditioning mechanism 5; An elbow air conditioning knob 72 that receives an operation for switching the power supply level in stages including on / off with respect to the elbow air conditioning mechanism 6 and a main switch 73 that performs on / off switching of the entire air conditioning are provided. In this embodiment, the seat air-conditioning switch 71 and the main switch 73 are provided on the upright standing surface as viewed from the seated person, and the elbow air-conditioning knob 72 is provided on the front standing surface, but the mounting mode is limited to this. It is not a thing.

  As another switching function, this embodiment embeds contact type seating switches 9 in two places of the seat 2 as shown in FIG. 4, thereby turning off the entire air-conditioning function for power saving when leaving the seat. Like to do. The seating switch 9 is provided at two diagonal positions so as to be simultaneously separated in the width direction and the depth direction of the seating surface, and the switch body between the three-dimensional lattices 51x and 51x of the flow path forming member 51 shown in FIG. 90 is placed with the detection end 91 facing upward, and the detection end 91 can be protruded and retracted with respect to the switch body 90 and is elastically biased in the protruding direction. It is something to detect. The seat switch 9 is encased in a stretch fabric 53 together with the flow path forming member 51 to form the seat air conditioning mechanism 5 shown in FIG. 4, and this seat air conditioning mechanism 5 further includes a stretch fabric 23 of the seat 2 shown in FIG.

Then, when the detection end 91 is pressed through the upholstery 23 and 53 by the load of the seated person, the switch is turned on to detect the pressure receiving state.

  FIG. 9 schematically shows the switching function of the switching circuit 8 described above. In this embodiment, the battery 10 is adopted as the power source, and the battery 10 and the motor M1 of the seat air conditioning mechanism 5 are connected via the main switch 73, the seating switch 9, and the seat air conditioning switch 71. And the motor M <b> 2 of the elbow air conditioning mechanism 6 are connected via a main switch 73, a seating switch 9 and an elbow air conditioning knob 72. As a switching function, when the seat switch 9 detects the seating while the main switch 73 is ON, the seat air-conditioning mechanism according to the operation status of the seat air-conditioning switch 71 and the elbow air-conditioning knob 72. When the power supply to the elbow air conditioning mechanism 6 is turned on and off and the energization amount (that is, the air flow) is switched, and the two seating switches 9 are both turned off and the absence of the seat is detected, the seat air conditioning is performed. The power supply to the motors M1 and M2 of the seat air-conditioning mechanism 5 and the elbow air-conditioning mechanism 6 is stopped regardless of the operation status of the switch 71 and the elbow air-conditioning knob 72. Of course, both air-conditioning mechanisms 5 and 6 are disconnected from the battery 10 even when the main switch 73 is in the OFF state. The figure only illustrates one function, and the configuration of the operation means 7 and the switching function of the switching circuit 8 can be variously modified.

  Furthermore, in this embodiment, as shown in FIG.2 and FIG.10, the battery 10 is detachably set in the battery accommodating part 100 provided in a part of chair. The battery housing portion 100 is made of resin, and is supported by being hung together with the elbow 4 by using a bracket (not shown) when attaching the base of the elbow frame 41 to the outer shell 21 of the seat 2. Thus, the guide surface 100b for the battery 10 to be inserted is inclined so that the insertion port 100a opens obliquely upward toward the rear, and the power receiving terminal 100d is arranged on the front rear surface 100c to be the insertion destination. On the other hand, the battery 10 can be inserted into or removed from the battery housing portion 100 and can be removed and charged by an external charger. The power receiving terminal 100d is placed on the forward facing surface 10c at a predetermined insertion position. A power supply terminal 10d is provided at a portion that is electrically connected to the power supply terminal, and a remaining amount display unit 10e that notifies the remaining amount of the battery by the lighting state of the LED is provided beside it. The battery 10 includes a charging terminal (not shown).

  When the battery 10 is inserted into the battery housing portion 100 from the insertion port 100a, the battery 10 slides along the guide surface 100b to reach a predetermined position with its own weight, and the power supply terminal 10d is connected to the power supply terminal 10d using the battery load. An electrical connection state with the power receiving terminal 100d is established. A window 100e for opening the remaining amount display portion 10e of the battery 10 is opened at a position adjacent to the rearward surface 100c of the battery housing portion 100, and the remaining amount display portion 10e of the battery 10 inserted into a predetermined position. Is opened through the window 100e so that the battery remaining amount can be visually recognized from the front of the chair as indicated by an arrow F in FIG. As described above, the chair 2 has the seat 2 synchronized with the back 3 and tilts backward, and the battery accommodating portion is between the non-rearward tilt shown in FIG. 11A and the maximum rearward tilt shown in FIG. The angle of 100 changes with the angle of the seat 2. For this reason, the battery housing portion 100 described above is configured so that the inclination of the guide surface 100b extending in the direction from the insertion port 100a toward the insertion destination does not reverse in the reverse direction when the maximum backward inclination shown in FIG. The inclination angle at the time of non-rearward inclination shown in FIG. 11A is set.

  In the present embodiment, wirings are basically omitted. However, in order to realize the circuit configuration of FIG. 8 and FIG. 9 without exposing the wirings to the outside as much as possible, the elbow frame 41 is appropriately selected. Wirings are routed inside and outside the outer shell 21.

  In addition, by using a heater in part of the seat air conditioning mechanism 5 and the elbow air conditioning mechanism 6 in the above, it is also possible to generate warm air and input heat to the seated person.

  As described above, the elbow 4 with an air-conditioning function of the present embodiment includes the air outlet 61 that opens in a part of the elbow body 4x, the suction port 62 that opens in the other part of the elbow body 4x, and the air outlet. 61 and an internal flow path 63 formed between the suction opening 62 and an air blower 64 that is provided in the internal flow path 63 and receives power and sucks air from the suction opening 62 and blows it out from the blowing opening 61. The elbow body 4x is provided with operating means 7 that constitutes the air conditioning mechanism 6 and that receives an operation for switching the power supply state of the elbow air conditioning mechanism 6 to the blower 64.

  Thus, when the elbow part air-conditioning mechanism 6 is provided directly on the elbow 4 so as to individually generate the air flow, the flow path length has only to be kept to a minimum and the flow path resistance is a large load on the air blowing means. Therefore, it is possible to efficiently generate an air flow with a simple blower. Moreover, the elbow 4 itself is equipped with an air-conditioning mechanism, so it is possible to respond to individual differences, physical condition, etc., starting from the usage situation such as the environment, position, work contents, etc. where the chair is placed by changing only a part of the chair. An appropriate air-conditioning environment can be realized. In addition, since the air conditioning function is completed only at the elbow, there is no need to expose the pipe to the outside or to form a complicated flow path inside, and the appearance of the chair to be applied can be remarkably improved.

  As a specific configuration, a blower 64 and a wind direction adjusting unit 65 that makes the blowing direction of air from the blower 64 variable are incorporated as a unit between the suction port 62 and the blowing port 61 of the elbow air conditioning mechanism 6. Therefore, the elbow part air-conditioning mechanism 6 can be configured in a compact manner, and can be easily assembled, and the airflow loss can be effectively reduced by closely associating the airflow direction adjustment unit 65 with the blower 64. Become.

  In this case, since the wind direction adjusting part 65 is provided so as to be able to swing between the outlet of the fan 64x constituting the blower 64 and the outlet 61 to form the internal flow path 63, The flow of air generated by the blower 64 can be guided to the outlet 61 without loss and blown out freely in a required direction.

  In particular, in the present embodiment, the elbow body 4x includes an elbow frame 41 as a support portion and an elbow rest 42 that can move relative to the elbow frame 41, and includes at least the outlet 61, the suction port 62, Since the internal flow path 63 and the blower 64 are provided in the elbow rest portion 42 and the elbow rest air conditioning mechanism 6 is completed in the elbow rest portion 42, pipes and the like that impair appearance and operation are provided in the elbow rest portion 42. It is possible to eliminate the need for connection.

  From another point of view, the elbow body 4x includes an elbow rest part 42 and an elbow frame 41 as a support part for supporting the elbow rest part 42, and at least the internal flow path 63 and the blower 64 are provided in the elbow body 4x. Provided in the elbow rest 42, the outlet 61 is opened on the upper surface of the elbow rest 42, the suction opening 62 is opened on the lower surface of the elbow rest 42 facing the outlet 61, and the suction opening 61 is blocked. Since the elbow rest 42 is supported by the elbow frame 41 so that there is no gap, the length of the flow path is the shortest that only penetrates the thickness of the elbow rest 42, and the resistance of the flow path is a value close to the minimum. Can be suppressed. In addition, since the suction port 62 is not blocked by the elbow frame 41, it is possible to effectively avoid an increase in air suction resistance.

  The specific configuration of each unit is not limited to the above-described embodiment.

  For example, in the above embodiment, the elbow 4 is configured to rotate. However, as shown in FIG. 12, the elbow 104 may be moved by a slide or a fixed elbow. Even in such elbows other than movable elbows, as shown in the figure, the elbow body air-conditioning mechanism 106 is configured by providing the elbow body 104x with a blowout port 161, a suction port 162, an internal flow path 163, and a blower 164. By providing the operation means 107 for the blower 164 of the air conditioner 106 structure in the elbow body 104x, the same operational effects as in the above embodiment can be obtained. Also in this case, when the suction port 162 and the blowout port 161 are provided in the elbow pad 142, the elbow pad 142 is supported by a support unit 141 such as an elbow frame so as not to block the suction port 162. It is possible to avoid an increase in suction resistance.

  Furthermore, as shown in FIG. 13, it is also effective to provide the operation means 207 in the elbow rest part 242, and it is also effective to have a battery housing part 200 for detachably incorporating the battery 20 in the elbow rest part 242. Is. In the figure, a cover 200a is provided on the upper surface of the elbow rest 242 and the battery 20 can be attached and detached by opening the cover 200a. According to the configuration shown in the figure, the elbow air-conditioning mechanism 206 is completed with only the elbow rest 242 including the wiring, so even if the elbow rest 242 moves, the wiring cannot be pulled at all, and between the chair and the like. It is possible to completely eliminate the problem of exposing the wiring.

  Other configurations can be variously modified without departing from the spirit of the present invention.
