Description

  The present invention relates to a chair with an air-conditioning function that is particularly applicable when air-conditioning according to the work environment of a worker is required, 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. It is comprised including the ventilation means sent toward an exit.

  The air spout is provided in the armrest, and a sensor for detecting the absence of seat is incorporated in the support column that supports the seat.

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, since the length of the flow path is increased due to the air drawing, it is considered that there is still room for generating an air flow more efficiently when considering the flow resistance and the load of the air blowing means.

  In addition, considering the environment and position where the chair is placed, the usage status of the work, etc., and considering individual differences and physical condition, the degree of air suction from the seat and backrest and the amount of air from the armrest It is more preferable that the degree of the balloon can be adjusted individually rather than being uniform. It would be even more convenient if such a configuration for individual adjustment can simultaneously improve the above-described air blowing efficiency.

  In addition, in Patent Document 1, a seat switch is attached to the support column so that unnecessary power is not consumed when the user leaves the seat. However, since a high load acts on the support column, a simple sensor is used to achieve the required sensitivity. It is not easy to adjust, and it may be more difficult to detect when the support column moves up and down.

  An object of the present invention is to newly provide a chair with an air-conditioning function that realizes a configuration that balances these problems.

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

That is, the chair with an air-conditioning function of the present invention is such that the seat is rotatable with respect to the legs, and an elbow is attached to the side of the seat. A seat air-conditioning mechanism for generating a flow of air for controlling the temperature of the seat surface, an elbow air-conditioning mechanism for generating a flow of air that is provided on the elbow and receives electric power and blows out from the elbow toward the seating space, An operation unit that receives an operation on the seat part air-conditioning mechanism and an operation on the elbow part air-conditioning mechanism, and a switch that switches a power supply state to the seat part air-conditioning mechanism and the elbow part air-conditioning mechanism in accordance with an operation received by the operation unit. Means.
Here, the temperature control of the seating surface includes not only the effect of pumping the heat trapped in the seating surface by generating an air flow inside the seating but also the effect of heat input to the seating surface.
As described above, the present invention provides air conditioning mechanisms individually on the seat and the elbow to individually generate the air flow. Therefore, it is only necessary to secure the minimum flow path length in each case, and the flow path resistance is large in the air blowing means. It can avoid becoming a load. For this reason, even if a simple blower is employed for each air conditioning mechanism, an effective air flow can be efficiently generated. Moreover, by making the air-conditioning mechanism separate in this way, the operation means can accept individual operations, so the environment and position where the chair is placed, the usage status of the work content, etc. Depending on the physical condition and the like, a finer air conditioning environment can be realized.
In order to ensure good operability, it is desirable that the operating means be provided at a position on the elbow or around the elbow and operable by a seated person in a sitting posture.
In order to achieve both operability and an effective air conditioning function, the operating means accepts an operation for switching on / off of power supply to the seat air conditioning mechanism, and includes power supply including on / off for the elbow air conditioning mechanism. It is preferable to be configured to accept an operation for switching the level.
In order to easily and appropriately realize the power saving function when leaving the seat, a contact-type seating switch is embedded in the seat, and the switching means is operated when the seating switch detects the seating. The seat air conditioning mechanism and the elbow air conditioning mechanism are switched in response to each other, and the seat air conditioning mechanism and the elbow are controlled regardless of the operation status with respect to the operation means when the seating switch detects the absence of the seat. It is effective that the power supply to the air conditioning mechanism is stopped.
In this case, in order to prevent detection omission due to the movement of the seated person's body, it is desirable to provide the seating switches at a plurality of locations separated in the width direction and / or the depth direction of the seating surface.
Even in this case, in order to minimize the number of seating switches, it is effective to provide the seating switches at diagonal positions that are simultaneously separated in the width direction and the depth direction of the seating surface.
In order to reliably detect the seating without touching the seating switch, the seat is covered with a tensioning cloth together with the seating switch, and the detection end of the seating switch is provided at a position facing the tensioning cloth, It is preferable that the pressure receiving state is detected.

  Since the chair with an air-conditioning function of the present invention has the above-described configuration, each seated person can appropriately adjust the seat temperature adjustment function and the air blowing function to the seating space through the operating means. Air conditioning environment can be prepared, and at the same time, each air-conditioning mechanism is made independent to eliminate the need for complicated flow passages and to effectively realize a highly efficient air-conditioning function using a simple blower. It becomes possible.

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 chair with an air-conditioning function of the present embodiment is a chair in which the seat 2 is rotatable with respect to the leg 1 and the elbow 4 is attached to the side of the seat 2. A seat air-conditioning mechanism 5 that is provided and receives electric power to generate an air flow for adjusting the temperature of the seat surface inside the seat 2, and is provided on the elbow 4 and receives electric power from the elbow 4 toward the seating space. The elbow part air-conditioning mechanism 6 that generates a flow of air to be blown out, the operation means 7 that receives the operation on the seat air-conditioning mechanism 5 and the operation on the elbow part air-conditioning mechanism 6, and the operation that is received by the operation means 7 It comprises switching means 8 for switching the power supply state for the seat air conditioning mechanism 5 and the elbow air conditioning mechanism 6.
As described above, in this embodiment, the air flow mechanisms 5 and 6 are individually provided on the seat 2 and the elbow 4 to individually generate the air flow. It can be avoided that the resistance becomes a large load on the blowing means. For this reason, even if it employ | adopts the simple air blowers 52 and 64 for each air-conditioning mechanism 5 and 6, it becomes possible to produce | generate an effective air flow efficiently. In addition, by making the air-conditioning mechanisms 5 and 6 separate as described above, the operation means 7 can individually accept operations, so that the environment and position where the chair is placed, the usage status of the work contents, etc. In addition, it becomes possible to realize a finer air conditioning environment according to individual differences and physical condition.

  Particularly, since the operating means 7 is provided at a position that is a part of the elbow 4 and can be operated by a seated person in a sitting position, the seat air-conditioning mechanism 5 and the elbow while the seated person put his hand on the elbow 4 It is possible to perform operations on both the air conditioning mechanisms 6 and to appropriately adjust both the air conditioning mechanisms 5 and 6 while experiencing the air conditioning effect.

  In general, the air blown from the elbow 4 toward the seating space directly acts on the seated person and is immediately experienced. Therefore, fine switching of the air volume and the like is effective, whereas the temperature control on the seat surface is There are places that are difficult to experience immediately. On the other hand, the operation means 7 of the present embodiment accepts an operation for switching on / off of power feeding to the seat air conditioning mechanism 5 and switches the power feeding level including on / off to the elbow air conditioning mechanism 6. Therefore, an effective adjustment function can be realized while avoiding complicated operations.

  Further, a contact-type seating switch 9 is embedded in the seat 2, and when the seating switch 9 detects the seating in the switching means 8, the seat air-conditioning mechanism 5 and the seating part air conditioning mechanism 5 and When the power supply state for the elbow air-conditioning mechanism 6 is switched and the seat switch 9 detects the absence of the seat, the seat air-conditioning mechanism 5 and the elbow air-conditioning mechanism 6 are operated regardless of the operation status of the operation means 7. Compared to the case where a seating switch is attached to the column, the load is distributed on the seat surface, and it is not necessary to detect the part where the high load acts. Can be used to properly detect absence from the seat with the required sensitivity. Moreover, since the number of seating switches 9 to be used and the installation location are flexible as long as they are seated, the design according to the purpose and application is facilitated, and the lifting mechanism can be used even in a chair in which the seat 2 moves up and down. It becomes possible to apply without hindrance.

  In particular, the seating switch 9 of the present embodiment is provided at two locations separated in the width direction and the depth direction of the seating surface, so that detection omissions can be prevented even if the seating position of the seated person changes in front, back, left, and right. In addition, since the seating switches 9 are provided at diagonal positions so as to be simultaneously separated in the width direction and the depth direction of the seating surface, it is possible to cope with changes in the seating position from front to back and left and right with the minimum number of seating switches. It becomes possible.

  In addition, the seat 2 is covered with the tension switch 53 together with the seat switch 9, and the detection end 91 of the seat switch 9 is provided at a position facing the tension fabric 53, and the pressure receiving state is detected via the tension fabric 53. Since the seating switch 91 can be hidden by the upholstery 53 or the like, the seating switch 91 can be set to enter even if the upholstery 53 or the like is pulled. Even when seated at a position deviated from the seating switch 9, the seating state can be detected effectively, and this point is also effective as a configuration in which the number of seating switches 9 is reduced without degrading accuracy.

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

  For example, in the above-described embodiment, the air blower 52 is arranged on the front edge side of the seat 2 to suck in air, and the seat air conditioning mechanism 5 is configured to exhaust from the rear edge side of the seat 2, but as shown in FIG. Even if the air-conditioning climate 105 is configured such that the blower 152 is arranged on the rear edge side of the seat 2 to suck in air and exhaust the air from the front edge side of the seat 2, the same effect as described above can be obtained.

  In addition, as shown in FIG. 13, the seating switch may be provided so as to form two vertical rows and two horizontal rows at four positions of the seat 2, and the configuration of five or more is not hindered. On the contrary, if the detection accuracy is not lowered, it is possible to arrange at only one location in the center, or only in one vertical row and only in one horizontal row.

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