In a manually operated air conditioner, a temperature setting button is provided in the air conditioning operation unit, and the set temperature is numerically displayed on the air conditioning operation unit. In the fully automatic air conditioner, the temperature of the temperature-controlled air that has been automatically set is numerically displayed on the air conditioning operation unit as a numerical value (for example, Patent Document 1).
JP 7-149139 A

  In a conventional vehicle air conditioner, the temperature of the temperature-controlled air is only displayed numerically on the air conditioning operation unit. There is no choice but to directly experience the temperature-controlled air (air-conditioning air) blown out of the air outlet with the hands and face close to the air outlet of the air conditioner provided in the vehicle interior member. It is difficult to get the state sensuously.

  The problem to be solved by the present invention is to make it possible to obtain the temperature state of the temperature-controlled air blown out from the air outlet in a sensuous manner, in particular, by the occupant's eyesight.

  In order to solve the above-mentioned problems, an air conditioner for a vehicle according to the present invention illuminates an air outlet provided in a vehicle interior member and blows out temperature-controlled air from an air conditioning duct into a vehicle interior, and the air outlet. And an emission color control unit that changes and sets the emission color of the illumination unit based on the temperature of the temperature-controlled air.

  In the vehicle air conditioner according to the present invention, preferably, the emission color control means lowers the color temperature emitted by the illumination means as the temperature of the temperature-controlled air increases, and decreases as the temperature of the temperature-controlled air decreases. The color temperature at which the illumination means emits light is increased.

  In the vehicle air conditioner according to the present invention, preferably, the higher the temperature of the temperature-controlled air, the longer the emission wavelength of the illumination means, and the lower the temperature of the temperature-controlled air, the shorter the emission wavelength of the illumination means. .

  The vehicle air conditioner according to the present invention preferably further includes a breathable sheet that covers the air outlet in a state where the illumination unit is disposed on the back surface side.

  According to the vehicle air conditioner of the present invention, the illumination color of the illumination unit is changed and set based on the temperature of the temperature-controlled air, so that the illumination color of the air outlet illuminated by the illumination unit is the temperature-controlled air. Depending on the temperature, the temperature of the temperature-controlled air blown out from the air outlet can be visually felt from the illumination color.

  The illuminating color of this lighting means, that is, the lighting color of the air outlet, is blue when the temperature of the temperature-controlled air is lower during cooling and lower when the temperature of the temperature-controlled air is lower, and when the temperature of the temperature-controlled air is higher during heating. Any warm red color may be used.

  Below, one embodiment of the air harmony device for vehicles by the present invention is described with reference to FIGS.

  As shown in FIG. 1, the vehicle air conditioner (vehicle air conditioner) of the present embodiment includes an instrument panel 11, a door garnish 12, a rear shelf 13, a front seat seat 14, and a front seat. Each of the backrest portion 15, the rear seat seat portion 16, and the rear seat backrest portion 17 has an air outlet 31 that blows temperature-controlled air into the vehicle interior.

  That is, the instrument panel 11, the door garnish 12, the rear shelf 13, the front seat portion 14, the front seat back portion 15, the rear seat seat portion 16, and the rear seat back portion 17 are all inward of the frame shape. The frame 20 has a closed annular frame 20 that defines the in-frame air chamber 21 and a breathable sheet 30 stretched on the surface where the in-frame air chamber 21 faces the vehicle interior. The frame 20 is a ventilation duct 22 (FIG. 2). The frame body 20 has an air outlet 23 (see FIGS. 2 and 3) that is open to the in-frame air chamber 21 and communicates with the ventilation duct 22. Is formed. The breathable sheet 30 covers the entire surface of the frame air chamber 21 facing the vehicle interior, and the portion of the breathable sheet 30 corresponding to the frame air chamber is a substantial air outlet 31 for the vehicle interior.

  2 and 3 show details of the instrument panel 11. The instrument panel 11 is provided along the lower edge of the front windshield glass 18 and is provided on the vehicle interior side of the front windshield glass 18.

  The instrument panel 11 includes a closed annular frame 20, and the frame 20 defines an in-frame air chamber 21 having an upper opening having a relatively large internal volume inward of the frame shape. The frame body 20 has a hollow structure that defines the ventilation duct 22, and the inner circumferential surface (the surface where the frame body 20 faces the in-frame air chamber 21) 24 communicates with the ventilation duct 22 to form a frame. A plurality of air outlets 23 opened toward the inner air chamber 21 are formed. The ventilation duct 22 is connected in communication with an air conditioning duct 51 (see FIG. 1) of the in-vehicle air conditioner, and is supplied with temperature-controlled air of the air conditioner by the air conditioning duct 51.

  The breathable sheet 30 is composed of a breathable sheet material such as a mesh cloth represented by a saran net, a porous sheet, or the like, that is, a breathable structure sheet material through which air can pass through each of a large number of ventilation portions. The instrument panel 11 is stretched on the upper surface (design surface) of the instrument panel 11 as a cover material (skin material), covers the entire surface (upper surface) of the frame air chamber 21 facing the vehicle interior, and corresponds to the air chamber 21 in the frame. The entire region is an air outlet 31 for the passenger compartment.

  The temperature-controlled air from the air conditioning duct 51 of the in-vehicle air conditioner flows through the ventilation duct 22 and enters the in-frame air chamber 21 having a larger internal volume than the lateral air outlet 23, and the flow velocity is reduced. Then, as the internal pressure of the in-frame air chamber 21 increases, the temperature-controlled air in the in-frame air chamber 21 passes through a large number of ventilation portions of the breathable sheet 30 and has a size corresponding to the in-frame air chamber 21. The air is blown out from the air outlet 31 into the vehicle interior space.

  As a result, air is blown into the vehicle interior space from a large planar air outlet 31 comparable to the size (opening area) of the in-frame air chamber 21, and this air diffuses without blowing out with strong directionality. It blows out into the passenger compartment space with a slow flow. As a result, the air (wind) blown out from the air outlet 31 into the vehicle interior space is strongly irritating and does not directly hit the occupant, but becomes an indirect wind, and at the same time, heat diffusion is improved. The temperature can be controlled with a natural and gentle feeling.

  On the inner peripheral surface 24 of the frame body 20, linear light emitting means (light source) 25 is provided as an illuminating means for the air outlet 31 so as to border the outline of the air outlet 31. The light emitting means 25 is on the back side of the air-permeable sheet 30 (on the side of the in-frame air chamber 21), and indirectly illuminates almost the entire air outlet 31 so as to border the in-frame air chamber 21.

  In other words, the air permeable sheet 30 covers the air outlet 31 in a state where the light emitting means 25 is disposed on the back side of the sheet. Thereby, the light emitted by the light emitting means 25 is diffused when passing through the air permeable sheet 30, and is seen as soft indirect illumination light through the air permeable sheet 30 on the vehicle interior side without giving strong irritation to eyes. It is done.

  The light emitting means 25 is composed of a device capable of changing the light emission color, such as a linear arrangement of full color display light emitting diodes in which RGB LED chips are packaged. Accordingly, light emission of a hue corresponding to the temperature of the temperature-controlled air, that is, the temperature of the air blown from the air outlet 31 is performed.

  FIG. 4 shows a control system of a fully automatic in-vehicle air conditioner. The control unit of the in-vehicle air conditioner is of a microcomputer type and has a necessary outlet temperature calculating means 101. The necessary air outlet temperature calculating means 101 receives information signals from the inside air temperature sensor 102 that detects the vehicle interior temperature, the outside air temperature sensor 103 that detects the outside air temperature, and the solar radiation sensor 104 that detects the solar radiation state. The optimum required outlet temperature is calculated according to the signal by a preset calculation method. The necessary air outlet temperature calculating means 101 outputs a command value signal, which is a calculation result of the necessary air outlet temperature, to the air outlet temperature control unit 105 and the emission color control unit 106.

  The blowout temperature control unit 105 performs drive control of the blowout temperature operation unit 107 by an air mixing damper or the like according to the necessary blowout port temperature calculated by the necessary blowout port temperature calculation unit 101. Thereby, the blowing air temperature of the air blower outlet 31 is set to the optimal required blower outlet temperature according to the vehicle interior temperature, the outside air temperature, and the solar radiation state.

  The light emission color control unit 106 controls the light emission hue of the light emitting means 25 according to the required air outlet temperature (temperature of the temperature-controlled air) calculated by the required air outlet temperature calculating means 101. In this light emission hue control, the higher the temperature of the temperature-controlled air, the lower the color temperature at which the light-emitting means 25 emits light, and the lower the temperature of the temperature-controlled air, the higher the color temperature at which the light-emitting means 25 emits light. Alternatively, the emission wavelength of the light emitting means 25 is lengthened as the temperature of the temperature-controlled air is higher, and the emission wavelength of the light-emitting means 25 is shortened as the temperature of the temperature-controlled air is lower.

  Thereby, for example, as the temperature of the temperature-controlled air at the time of cooling, that is, as the temperature of the air blown from the air outlet 31 is lower, the light emitting means 25 emits light blue and the air outlet 31 is heated. As the temperature of the blown air rises, the light emitting means 25 emits a warm red color.

  The illumination color of the air outlet 31 changes depending on the color emitted by the light emitting means 25, and the illumination color of the air outlet 31 corresponds to the temperature of the temperature-controlled air. The temperature state of the temperature-controlled air can be easily felt visually and in color.

  FIG. 5 shows details of the door garnish 12. 5, parts corresponding to those in FIGS. 1 to 3 are denoted by the same reference numerals as those in FIGS. 1 to 3, and description thereof is omitted.

  The door garnish 12 has a closed annular frame 20 in the armrest portion 12A. The frame body 20 of the door garnish 12 defines an in-frame air chamber 21 having a side opening on the vehicle interior side inside the frame shape. The frame body 20 also has a hollow structure that defines a ventilation duct (not shown), and the inner circumferential surface 24 of the frame body 20 (the surface where the frame body 20 faces the in-frame air chamber 21) communicates with the ventilation duct. Thus, a plurality of air outlets 23 opened toward the in-frame air chamber 21 are formed. The ventilation duct 22 of the frame 20 of the door garnish 12 is also connected to the duct 51 of the in-vehicle air conditioner, and the temperature-controlled air of the air conditioner is supplied by the duct 51 (see FIG. 1).

  A breathable sheet 30 is stretched in a manner that the air chamber 21 in the frame of the armrest portion 12A faces the vehicle interior. The breathable sheet 30 of the armrest portion 12A is also made of a breathable sheet material such as a mesh cloth represented by a saran net or a porous sheet, and the entire surface on which the in-frame air chamber 21 faces the vehicle interior. The entire region corresponding to the in-frame air chamber 21 is an air outlet 31 for the vehicle interior.

  Thereby, also in the door garnish 12 part, air blows out into the vehicle interior space from a large planar air outlet 31 comparable to the size (opening area) of the air chamber 21, and this air blows out with a strong directivity. There is not, and it blows out into the passenger compartment space with a diffused slow flow.

  A linear light emitting means 25 is also provided on the inner peripheral surface 24 of the frame 20 in the armrest portion 12A so as to border the outline of the air outlet 31. Similarly to the instrument panel 11 portion, the light emitting means 25 is on the back side of the breathable sheet 30 (on the frame air chamber 21 side) and serves as a lighting means for the air outlet 31, and borders the frame air chamber 21. As shown, the air outlet 31 is indirectly illuminated. The light emitting means 25 also emits light in a hue corresponding to the temperature of the air blown from the air outlet 31 (temperature of the temperature-controlled air), so that the occupant can also use the vehicle air conditioner at the air outlet 31 of the armrest portion 12A. The operating status (air conditioning temperature state) can be grasped visually and sensuously.

  In addition, the illumination means of such an air blower outlet 31 is the air blower outlet 31 of each part of the rear shelf 13, the front seat seat part 14, the front seat backrest part 15, the rear seat seat part 16, and the rear seat backrest part 17. The air conditioning temperature state of the in-vehicle air conditioner can be visually and sensibly grasped at each part in the vehicle interior.
