Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a vehicle heating device for heating a driver's cab and a nap room in a vehicle such as a truck that has both a driver's cab and a nap room.

[Conventional technology]

Conventionally, in order to heat the nap room of a vehicle such as a truck when the vehicle is parked, the vehicle engine is normally operated in idling mode to continue circulating and supplying high-temperature engine cooling water to the heater core of the driver's cab heating system, and then the heating system heats the room. The heated air was introduced into the nap room.

[Problem that the invention seeks to solve]

However, with the above method, the vehicle engine must continue to run when the vehicle is parked to heat the nap room, and the problem is that fuel consumption is high, especially since the trunk is equipped with a large engine.

In addition, engine noise disturbs naps, and running the engine causes problems with exhaust gas and noise, and it is often difficult to find a parking space.

[Means for solving problems]

Therefore, in order to solve the conventional problems as described above, the present invention provides a vehicle having both a driver's cab and a nap room, and includes: a heat storage container disposed in the nap room and storing a heat storage medium therein; and the heat storage container. The present invention employs a heating device for a vehicle, which includes a heat source means disposed in the M heat medium and supplying heat to the M heat medium.

[Effect]

According to the above means, the heat of the heat source means is stored in the heat storage medium,
The nap room can be heated by dissipating the heat stored during parking naps.

(Effects of the Invention) Therefore, according to the present invention, there is no need to idle the vehicle engine when the vehicle is parked in order to heat the nap room, and the fuel consumption of the vehicle engine can be reduced. This has the great effect of allowing you to take a nap in a comfortable environment.

Furthermore, since engine noise and exhaust gas emissions are eliminated during parking, it becomes easier to secure a parking space.

〔Example〕

Hereinafter, the present invention will be explained based on embodiments shown in the drawings.

FIG. 1 is a schematic diagram showing the state in which the vehicle heating system of the present invention is mounted on a truck, where 10 is a driver's cab of the truck, and 11 is a nap room formed on the rear side of the driver's cab 10, with partitions such as curtains. It is separated from the driver's cab 10 by a member 12. 13 is a bed in the nap room 11. 14 is driver's cabin 1
The heating unit 15 for heating the driver's cabin is arranged in the lower part of the instrument panel 14.

This heating unit 15 includes an air blower 15b and a heater core 15 through which engine cooling water is passed inside a casing 15a.
c is housed, and warm air is blown out from the air outlet 15d. Also, 16 is a vehicle engine, and 17 is this engine 1.
This is a radiator that cools the cooling water of No. 6, and is configured such that engine cooling water is circulated to the heater core 15C through a hot water pipe 18 through an outgoing path 18a and an incoming path 18b. 19 is a solenoid valve that controls the supply of engine cooling water to the heater core 15c.

A heat storage device section 20 of the heating device of the present invention is arranged and fixed at the bottom of the bed river 3 of the nap room 11, and this M heat device 2
The structure of 0 is shown in FIG. Reference numeral 21 denotes a metal or resin container shaped like a rectangular hand box, and a heat insulating material 22 made of felt material, resin foam, or the like is provided around the entire outer periphery of the container. A heat supply pipe 23 formed by bending a metal pipe into a meandering shape is housed in the container 21, and its entrances and exits 232, 23
b is drawn out to the outside of the container 21 in an airtight manner.

As shown in FIG.
It is connected to an outgoing path 24a and a returning path 24b of a hot water pipe 24 that branches from 8a and joins the incoming path 18b. Furthermore, this heat storage container 21 is filled with a heat storage medium 30 made of sodium acetate hydrate with a melting point of 58°C. Heat can be stored by latent heat accompanying the state change between the gel phase and the gel phase. Note that this sodium acetate hydrate is a substance that noticeably exhibits the so-called supercooling phenomenon in which it does not crystallize even when it is cooled from a gel state to a temperature below its melting point. An anti-supercooling agent consisting of a crystal nucleating agent such as sodium chloride decahydrate is mixed. Also, if necessary, increase the number of t7N.
A thickener such as No. 1 may be added to stabilize the operation of the heat storage medium. Further, the inner surface of the container 21 (if made of metal) and the outer surface of the heat supply pipe 23 are subjected to anti-corrosion treatment to prevent corrosion by sodium acetate.

Then, the outgoing path 24a (or incoming path 24b) of the hot water piping 24
) is provided with a solenoid valve 25 that opens and closes the pipe (this may be omitted).

Next, the operation of the above configuration will be explained. During normal driving, when the engine cooling water temperature is rising, when the driver turns on the heat storage switch (not shown) on the driver's seat of the vehicle, the solenoid valve 25
is opened and high temperature engine cooling water is introduced into the heat storage device 20. The heat of the engine cooling water is supplied to the heat storage medium 30 via the heat supply vibrator 23, and when the engine cooling water temperature is 58°C or higher, the sodium acetate hydrate, which is the heat storage medium 30, becomes a gel state and heat storage occurs. When the driver stops the vehicle, latent heat associated with crystallization and sensible heat of high-temperature substances are released from the heat storage medium 30, and the heat is gradually radiated by the heat insulating material 22 covering the container 21. It is possible to heat a driver who is napping on top of the car for a long time.

Next, in the present invention, the shape of the heat storage device can be modified in various ways. For example, the heat supply vibe 23 may be bent into a meandering shape, or it may be branched into a large number of pipes using branch pipes to pass through the heat storage medium 30. Further, the N heat medium 30 and the engine cooling water may be in thermal contact with each other in a layered structure, and the heat supply vibe 23 may be configured with a double pipe and the heat storage medium 30 may be enclosed on the outer circumferential side. . In short, it is sufficient that the heat storage medium and engine cooling water are arranged with good heat transfer efficiency, and many other modifications are possible in addition to the above. Alternatively, the heat storage medium 30 may be packed in a removable bag or the like to form a heat storage puncture, which can be removed when unnecessary, such as during summer. Note that if the shape of the heat supply vibrator 23 causes a large pressure loss for water supply, a water pump may be installed.

In the above embodiment, the heat storage device 20 is provided on the floor of the nap room 11 to heat the napping occupant from below, but the heat storage device 20 is provided on the wall 11a of the nap room 11, etc., so that natural convection can occur. Alternatively, the entire nap room may be heated by forced convection using a fan. Further, even when the heater is installed on the floor, it may be installed only at the feet as shown in Fig. 3 instead of over the entire surface, thereby providing comfortable heating for those with a cold head and warm feet, and the amount of N heat can be used effectively.

In addition, when the heat storage medium 30 is made by adding an anti-supercooling agent to sodium acetate hydrate, supercooling does not occur, so a special crystallization initiation device is not required. Since this is not possible, the supercooling inhibitor may be omitted. In this way, even after a long period of time after the engine has stopped, it is possible to provide a mechanical stimulation using an appropriate crystallization initiating device to start heat dissipation and perform heating. As the heat storage medium 30, in addition to sodium acetate hydrate, a wide range of known heat storage media such as inorganic salts whose phase changes with absorption and release of latent heat, polyolefin heat storage bodies, metals, and water can be used.

Further, the heat source means of the present invention may be an electric cotton heater powered by a battery in addition to the engine cooling water shown in the above embodiments, and by doing so, the structure becomes simpler and the battery is charged while driving. When it continues,
Since this battery power is used, there is no problem of battery draining.

Furthermore, the heating device of the present invention can be applied not only to trucks but also to so-called one-box cars and leisure vehicles with large interior spaces.
