Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a hot air type seat heater that introduces hot air into a seat cushion, mainly a rear seat cushion, and which heats the entire area of the seat cushion for a short period of time. The aim is to provide a hot air seat heater that can be used with high efficiency.

Conventional technology When using conventional heaters in the winter, especially during warm-up, the feet, which are easily hit by the hot air from the heater, warm up relatively quickly, but the lower back, especially the buttocks, have a large heat capacity and are slow to warm up because of the cold seat. There's a problem.

Structure of the Invention The present invention has been made in order to solve the above-mentioned problems, and is provided with a hot air chamber that extends over almost the entire area of the bottom of the seat cushion, and a warm air chamber that extends over almost the entire area of the bottom of the seat cushion. A hot air inlet made of a relatively hard hardboard material that has good sealing properties with the wind duct is provided, and a part of the hot air inlet is used to direct the introduced warm air to the entire bottom of the seat cushion. The warm air outlet of the heater is connected to the hot air inlet of the seat cushion, which is equipped with a warm air guide that flows evenly, through a duct that also serves as a backing.This configuration solves the above problem. This is what I did.

Embodiment FIG. 1 is a plan view showing an embodiment of the hot air type seat heater of the present invention, and FIG. 2 is an enlarged cross-sectional view of the same, which is applied to the seat of a Dyna vehicle.

In the figure, 1 is a floor, and 2 is a box-shaped seat pedestal fixed to the floor 1. A seat cushion 3 and a seat pack 4 are placed on this pedestal 2''. Near the front, a heater 5 having hot air outlets in two directions is installed with one of the hot air outlets 6 facing forward and the other hot air outlet lower facing the bottom surface of the seat cushion 3.

A recess 8 is provided at the bottom of the seat cushion 3 and extends over almost the entire area of the seat and cushion, and a warm air chamber 10 is formed with a vinyl sheet 9 stretched over the lower end surface of the recess 8.

The front and rear ends of the vinyl sheet 1-9 forming the lower end surface of the seat cushion 3 are attached to the frame of the seat cushion 3 so that hot air outlets 11 are formed on both sides, respectively, as shown in FIG. It is stretched around the horizontal wire 12, and is placed in a portion corresponding to the hot air blowing lower part of the heater 5.
A hot air inlet 15 is provided, which is constructed by attaching a relatively hard headboard material 14 that has excellent sealing properties with the backing duct) 13. A warm air guide 16 is provided to distribute the introduced warm air evenly over the entire bottom area of the seat cushion 3, and furthermore, the hot air guide 16 is provided to distribute the introduced warm air evenly over the entire bottom area of the seat cushion 3. A plurality of vertical holes 17 are arranged to guide the cushion 3 into the body. In the above configuration, the warm air guide 16 evenly distributes the warm air blown through the hot air introduction day 15 over the entire bottom area of the seat cushion 3. Any material may be used as long as it is possible, but in this embodiment, the bottom of the seat cushion is longer in the left-right direction than the rear, so for example, the 41st iffl (
As shown in A), the planar shape widens from the hot air inlet 18 toward the hot air outlet 19, and the side shape curves along the ceiling of the hot air chamber 10, as shown in FIG. As shown in the same figure (C), the top plate 21 of the flat duct 20 may be concave in an arc shape so that the area of the hot air outlet 19 is narrowed down gradually in the center, or 5
As shown in Figure (A), the planar shape is the warm air population 18a.
The end plate 22 is formed into a groove shape approximating a fan shape that opens toward the hot air outlet 019a, and the top plate 21a is bent toward the hot air outlet 19a side, as seen in the perspective view of the same figure (D). A warm air guide without a bottom plate with an arcuate tip may also be used.

In this case, the hot air from the hot air inlet 15 is blown onto the top plate 21a' and flows through the top plate 21a and the steel plates 23 on both sides, so even if there is no bottom plate, the area of the hot air outlet 19 can be reduced in the center. It has almost the same effect as the one shown in FIG. 4, which is narrowed down gradually.

Further, as shown in FIG. 6(A), a plurality of guide plates 24 are appropriately arranged in an arc shape on the II4-shaped top plate 21b, which has an arc-shaped planar shape and a curved side surface shape as shown in FIG. 4(B). It is good that it is set up. In this case, it is preferable that the distance g between the guide plates 24 on the hot air outlet 19b side be equal, and the distance on the hot air inlet 18b side be m>n>1.

In the hot air type seat heater according to the present invention configured as described in Operation of the Invention-I, a portion of the hot air blown from the heater 5 is delivered to the seat cushion 3 through the duct 13 which also serves as a backing and the hot air inlet 15. Warm air chamber 1 formed at the bottom of
blown into 0. Most of this hot air is evenly distributed over the entire bottom area of the seat cushion 3 by the hot air guide 16 that opens at the top of the inlet 15, and flows along the bottom surface of the seat cushion 3. The seat cushion 3 is heated until it reaches the warm air outlet 11. In this case, by adding vertical holes 17 as shown in the embodiment, the heating area can be increased and the time required for heating can be further shortened.

Effects of the Invention As described above, the present invention provides hot air introduced into the bottom of the seat cushion into two parts: the warm air chamber that extends over almost the entire area of the bottom of the seat cushion, and the hot air inlet of the warm air chamber. A warm air guide is provided to flow evenly over the entire bottom of the seat cushion, and the hot air inlet is connected to the warm air outlet of the heater via a duct that also serves as the backing, so the heater can be used at the same time. The warm air from the heater that flows into the warm air chamber at the bottom of the seat cushion can evenly heat almost the entire area at the bottom of the seat cushion, and the hot air flows along the bottom of the seat cushion inside the warm air chamber, making it highly efficient. Since the entire seat cushion can be heated in a short period of time, the seat cushion feels good when seated, and it can also warm the hands, providing excellent effects as a hot-air seat heater.
