Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an air conditioning panel installed in each office desk in a personal air conditioning system for efficiently heating or cooling the front surface of each office desk.

[0002]

[Prior art]

 As a type of office furniture, there is an office desk equipped with an air conditioning function. For example, as shown in FIG. 4, a personal air conditioner 10 is assembled between facing office desks A and B.

In this personal air conditioner 10, as shown in FIGS. 5 and 6, an air conditioning panel 10A whose front faces the office desk A side and an air conditioning panel 10B whose front faces the office desk B side are fitted to each other. Thus, the air conditioning panels 10A and 10B have a rectangular parallelepiped shape as a whole, and each of the air conditioning panels 10A and 10B has a shape in which the lower part 11 is divided into left and right parts and the upper part 12 is divided into front and rear parts. Consists of a base portion 12a located above the lower portion 11 and a protruding portion 12b extending from the base portion 12a to the right side when viewed from the front.

Each of the air conditioning panels 10A and 10B has a lower outlet 13 opened in front of a lower portion 11 which is lower than the tops of the office desks A and B, and the tops of the office desks A and B. An elongated upper outlet 14 that is opened on the front side of the upper portion 12 that is on the upper side and extends left and right from the base portion 12a to the protruding portion 12b, and is connected to the air-conditioning air passage under the floor by being opened on the bottom surface of the lower portion 11. The air-conditioning air intake port 15 is provided and a damper (not shown) blows out cool air from the upper air outlet 14 in the case of cooling and hot air from the lower air outlet 13 in the case of heating. Is selected. A punching metal or the like is provided at the opening of the lower outlet 13, and a louver or the like is provided at the opening of the upper outlet 14, so that the outlet angle can be adjusted appropriately.

[0005]

[Problems to be solved by the device]

 In forming the task area (the work area around the desk different from the ambient temperature) by the personal air conditioner 10, the lower air outlet 13 blows out warm air into the partitioned space under the top plate of the desk, so that the air is blown out. Although the performance is not so important, the upper outlet 14 blows cold air into the open space on the tabletop of the desk, and its blowing performance greatly affects the formation of a good task area. In order to form a good task area by cooling, it is important to perform uniform blowing at a flow velocity of 1.0 to 1.5 m / s over the entire top of the desk.

However, according to the above-described air conditioning panels 10A and 10B, in cooling, the conditioned air is passed through the internal space of the lower portion 11 from the conditioned air intake port 15 opened on the bottom surface of the lower portion 11 to the upper side. Although it is sent to the portion 12 and blown out from the upper outlet 14, as shown in FIG. 7, the flow velocity V of the air in the upper outlet 14 is high on the side of the base 12a and slower on the side of the protrusion 12b. It has a uniform distribution. This is because a part of the air sent to the base portion 12a of the upper portion 12 is immediately blown out from the upper blowout opening 14 at that position, but the flow pressure of the air toward the protruding portion 12b side is rapidly increased by this blowout. In addition, the air flow path in the upper part 12 has a depth that is half that of the air flow path in the lower part 11 and the left and right lengths are doubled. Is difficult to flow.

Therefore, in the left end portion of the upper outlet 14 in the drawing, air is blown out at a high flow velocity exceeding 1.0 to 1.5 m / s which is an appropriate flow velocity range, while the figure of the upper outlet 14 is shown. On the contrary, at the right end of the center, the flow velocity of the blowout is less than 1.0 m / s, which makes it difficult to form a comfortable task area around the office desks A and B.

The present invention has been made under the circumstances as described above, and its technical problem is to make uniform the flow velocity of the air blown out from the upper outlets that are long in the left and right directions. To form a good task area.

[0009]

[Means for Solving the Problems]

 The above technical problems can be effectively solved by the present invention. That is, the present invention has a shape in which a rectangular parallelepiped is divided into left and right portions at the lower portion and front and rear portions at the upper portion, and the upper portion is located above the base portion above the lower portion and in either the left or right direction from this base portion. In an air-conditioning panel, which comprises an extended protrusion and has an upper outlet that extends leftward and rightward from the base to the protrusion on the front surface of the upper portion, in the air flow path inside the upper outlet, A flow path throttle member is provided in which the gap of the throttle gradually increases from the base side toward the protruding side.

[0010]

[Action]

 The flow passage restricting member provides a throttle gap for the air flow that is about to immediately blow out from the upper outlet through the air flow passage in the base of the upper part from the inner space of the lower part of the air conditioning panel. Since it is made small, the flow velocity does not change, but the increase in the flow rate of the blowout on the base side is suppressed. This also suppresses the decrease in the air pressure of the air flowing toward the protruding part in the upper part, and since the gap between the throttles by the flow restrictor is large on the protruding part side, the flow velocity does not change, but the protrusion A decrease in the flow rate of air from the outlet on the part side is suppressed.

[0011]

【Example】

 FIG. 1 is a partially cutaway perspective view showing a schematic structure of a preferred embodiment of an air conditioning panel according to the present invention, and FIG. 2 is a perspective view showing a flow path throttle member incorporated in this embodiment. In FIG. 1, the same parts as those in the conventional example shown in FIGS. 4 to 6 are designated by the same reference numerals, and the description thereof will be omitted.

In this embodiment, a flow path throttle member 16 for adjusting the flow rate of air blown out from the upper outlet 14 is provided inside the upper portion 12a of the air conditioning panel 10A. The flow path restricting member 16 includes a pair of support plates 161 and 162 which are positioned at both left and right inner sides of the upper outlet 14 and are fixed in contact with the front wall 121 and the rear wall 122 of the upper portion 12a. A pair of diaphragm pieces 163, 164 are arranged in the lower part of the upper outlet 14 in contact with the front wall 121 and the rear wall 122, and both ends thereof are fixed to the support plates 161, 162. The diaphragm pieces 163, 164 have a substantially triangular shape in which the width gradually widens on the support plate 161 side, that is, on the base portion 12a side of the upper portion 12, and therefore, the diaphragm pieces 163, 164 are formed between the diaphragm pieces 163, 164. The throttle channel 165 that connects the air channel side in the portion 11 and the inner space of the upper outlet 14 has the smallest gap between the throttles at the end portion 165 a on the base 12 a side (the channel is narrow). , Toward the end portion 165b on the side of the protruding portion 12b, the diameter is gradually increased (the flow path is wide).

The flow restricting member 16 has the restrictive shape as described above to prevent the air flow blown from the upper blowing port 14 from being unevenly distributed on the base 12a side, and as shown in FIG. In addition, the distribution of the flow velocity V can be made uniform so as to be about 1.0 to 1.5 m / s in the entire right and left of the upper outlet 14. Therefore, a task area of a comfortable temperature environment is formed around the office desk (see FIG. 4) arranged in front of the air conditioning panel 10A by uniform blowing of cool air from the upper outlet 14.

In this embodiment, only the air conditioning panel 10A is described for convenience of explanation, but the other air conditioning panel 10B integrally fitted to the air conditioning panel 10A also has the completely same structure. Of course. Further, the shape of the throttle pieces 163, 164 should be a shape that generates throttle resistance corresponding to the flow velocity distribution when the flow path throttle member 16 is not provided, that is, a shape similar to the distribution curve shown by the broken line in FIG. Is more preferable, but a sufficient effect can be obtained even if the aperture amount is changed linearly as in this embodiment. Further, the flow path throttle member 16 does not necessarily have to include the pair of throttle pieces 163 and 164, and the same effect can be realized by using only a single throttle piece.

[0015]

[Effect of device]

 According to the air-conditioning panel of the present invention, the air blown from the lower part has a narrowing gap for the air flow at the base side of the upper part, which tends to immediately flow out to the upper blow-out port, so that it is difficult for the air to be sent. Since the flow rate to the side is increased, air can be blown out at an appropriate and uniform flow rate over the entire left and right sides of the blowout port, and a task area with a comfortable temperature environment can be formed.
