Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to an office desk equipped with an air conditioning function.

(Prior art) The present applicant has previously disclosed in Utility Application No. 61-44766,
The internal space of a vertical front panel, on which a desk top plate is mounted on the middle part of the front surface, is formed into a chamber for blowing out and sucking conditioned air, and a plurality of outlets and inlets for conditioned air are arranged on the surface of the panel, respectively. A supply duct and an exhaust duct for conditioned air connected to the air conditioning panel are connected to the lower part of the front panel, and a blind cover is attached to each of the air outlet and suction outlet to provide an air conditioning function. I proposed a new office desk.

(Problems to be Solved by the Invention) In the conventional system, the air outlets and suction ports are provided throughout the panel, and the ducts are complicated, resulting in uneven air flow from the air outlets, and when switching between heating and cooling, Depending on the location of the air outlet and suction port, complicated operations are required to open or close them.

(Means for solving the problems) The present invention relates to an office desk equipped with an air conditioning function, which was proposed to solve the above problems.
At the upper end of the upper part of the vertical front panel on which the desk top is mounted on the middle part of the front surface, there is provided an upper end opening that serves as an inlet for heating and as an outlet for cooling. At the lower end of the upper part and at the lower end of the lower part of the desk top plate, there is a suction port for cooling, respectively.
At the time of heating, an intermediate opening and a lower end opening that constitute an air outlet are provided, and a supply air connection port and a return air connection port that are connected to an air conditioner are provided at the bottom of the panel, and the air supply connection port is provided in the inner space of the panel. An air-conditioning duct consisting of a vertical duct that communicates with each air and return air connection port, and an upper, middle, and lower horizontal duct that branches out from the vertical duct and communicates with the upper, middle, and lower openings; The above problem is solved by installing a damper in the vertical duct that switches the air flow in the duct both upward and downward.

(Function) Since the present invention is constructed as described above,
During cooling, the damper is operated to supply cold air supplied from the air conditioner into the vertical duct from the air conditioner through the air supply connection port on the front panel to the upper horizontal duct, and an opening at the top of the front panel that communicates with the duct. The return air is blown out from the front panel to locally cool the area around the office desk, and the return air is sucked into the middle and lower ducts from the middle and bottom openings of the front panel, respectively, and introduced into the vertical duct, and is then sent to the air conditioner through the return air connection port. return.

During heating, the damper is switched, and the warm air introduced into the vertical duct from the air supply connection is supplied to the lower and middle ducts, and is blown out from the lower end and middle opening of the front panel that communicates with the ducts to the area around the office desk. The return air is sucked into the upper duct through the opening at the upper end of the front panel, introduced into the vertical duct, and returned to the air conditioner through the return air connection port.

(Effects of the invention) As described above, according to the invention, by switching the switching damper attached to the air conditioning duct built into the front panel, the air flow in the air conditioning duct is switched upward, and during cooling. Cool air is blown out from the top opening of the front panel, and warm air is blown out from the middle and bottom openings of the front panel during heating, eliminating the need to open and close the front panel air outlet and suction port when switching between air conditioning and heating. The heating/cooling switching operation is simplified, and the cooling/heating air outlet and suction port are provided only at optimal positions, improving the cooling/heating effect.

Furthermore, since each of the openings serves as both a hot and cold air outlet and an inlet, the number of these openings can be reduced, the length of the duct can be shortened, and the configuration can be simplified.

(Example) The present invention will be described below with reference to the illustrated embodiments.

A is a front panel of the office desk, B is a pair of left and right side panels, and C is a top plate disposed between the middle portions of the panels A, B, and B.

A required number of upper end openings 1 are arranged horizontally at the upper end of the upper part of the top plate of the front panel A, and a required number of intermediate openings 1 are arranged horizontally at the lower end of the upper part of the top plate and the lower end of the panel. 2 and a lower end opening 3 are arranged in a row, and furthermore, a supply air connection port 4 and a return air connection port 5 connected to an air conditioner are provided on the sides of the lower part of the top plate of the front panel A.

The air conditioner was proposed by the applicant in Utility Application No. 1982-29124, which had a drawer in the front part and a built-in radiator for air conditioning in the rear part of the casing, which had the same dimensions as the side table. However, a desk fan coil unit with casters attached to the bottom of the casing is used.

Inside the hollow part of the front panel A, there are a vertical duct 7 in which a switching damper 6 is attached, and an upper horizontal duct 8 that extends horizontally from the upper end of the duct 7 and communicates with the upper end opening 1 through an opening 8a. , a lower horizontal duct 9 that extends horizontally from the lower end of the vertical duct 7 and communicates with the lower end opening 3 via the opening 9a, and a lower horizontal duct 9 that is connected to the duct 9 via a vertical rising duct 10 and has an opening. An air conditioning duct consisting of a middle horizontal duct 11 communicating with the middle opening 2 via 11a is built-in.

In the figure, 12 is a heat insulating material for the duct.

Since the illustrated embodiment is constructed as described above, when the damper 6 is switched to the position shown by the solid line in FIG. 1 during heating, the warm air supplied into the vertical duct 7 through the air supply connection port 4 Lower horizontal duct 9,
The air is supplied to the middle horizontal duct 11 and blown out from the lower end opening 3 and middle opening 2 of the front panel A to locally heat the area around the office desk.

On the other hand, return air from the room is sucked into the upper horizontal duct 8 through the upper end opening 1 of the front panel A, and is introduced from the same duct 8 into the vertical duct 7 to return air connection port 5.
It is returned to the air conditioner.

Next, when the damper 6 is switched to the dotted line position in FIG. 1 during cooling, a downward airflow is generated in the air conditioning duct in place of the upward airflow during heating.

That is, the cool air supplied to the vertical duct 7 through the air supply connection port 4 is blown out from the upper end opening 1 of the front panel A through the upper horizontal duct 8, and locally cools the area around the office desk.

On the other hand, return air from the room is sucked into the middle horizontal duct 11 and the lower horizontal duct 9 from the intermediate opening 2 and lower end opening 3 of the front panel A, respectively, and enters the vertical duct 7, and then enters the vertical duct 7 through the return air connection port 5 for air conditioning. returned to the device.

Thus, according to the embodiment, the front panel A
Warm and cold air is selectively supplied through the openings 1, 2, and 3 provided in the panel A by switching the damper 6 of the air conditioning duct built into the panel A. The trouble of opening and closing the air outlet and suction port on the front panel is omitted, and the openings 1, 2, and 3 serve as both the air outlet and the air inlet for hot and cold air, so the number of openings is reduced and the duct size is reduced. The configuration is also simplified.

In addition, the outlet for cooling and heating air is in the optimal position, so
This improves the heating and cooling effect.
