Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a humidifying cooler for a vehicle which gives a passenger a feeling of cool air by atomized water obtained by atomizing water, and more particularly to an open-cabin type such as a forklift, a tractor, a crane truck, and a bulldozer This technology is suitable for use in work vehicles.

[0002]

2. Description of the Related Art Conventionally, as a technique for giving an occupant a cool air feeling by using atomized water, a humidifier is attached to a lower portion of a window on an inner wall of a vehicle door, and the humidifier is directed toward the passenger's face.
It is known that atomized water, which is atomized from water, is sprayed to give spot-like cold air to the occupants.

[0003]

The humidified air blown from the humidifier toward the occupant's face drops in temperature because the atomized water mixed in the wind takes away heat from the surrounding wind and evaporates. The wind (cold air) gives the occupant a feeling of cold air, but the degree of temperature decrease of the cold air changes depending on the temperature and humidity used. For this reason, even if it is desired to further lower the cold air temperature, it is not possible to meet the passenger's request.

Therefore, it is conceivable to use cold water as the water atomized by the humidifier, but the degree of decrease of the cold air temperature with respect to the sensible heat of the water temperature is small, and the effect of further lowering the cold air temperature is small. Further, if the refrigeration cycle is used, sufficient cold heat can be obtained and cold air that can be satisfied by the occupant can be obtained, but the cost is significantly increased, and the merit of the humidified cold air as a simple cooler is lost.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object thereof is to provide a merit as a simple cooler which gives a passenger a cool air feeling by atomized water.
It is intended to provide a humidifying cool air blower for a vehicle, which can lower the temperature of the cold wind due to humidification.

[Means for Solving the Problems]

[Means for Claim 1] By adopting the technical means for claim 1, the following effects are achieved. When the blower and the atomizing means are activated when the cool storage unit (the one in which the cool storage agent is enclosed in the container or ice) is not stored in the cool storage material unit, an air flow toward the passenger is generated in the air passage. At the same time, the atomized water is mixed in the air flow toward the occupant. Therefore, the humidified air mixed with the atomized water is blown out toward the occupant from the air outlet. The atomized water in the humidified air blown out from the air outlet removes heat from the surrounding air and evaporates, lowers the temperature of the humidified air, and becomes cold air toward the occupant.

When the regenerator material is stored in the regenerator material unit and the blower and the atomizing means are operated, the regenerator material accommodated in the regenerator material unit and the air passing through the air passage exchange heat. The air passing through the air passage becomes cool air. Since the cold air blown out from the air outlet contains the atomized water as described above, the atomized water takes heat from the surrounding air and evaporates, further lowering the temperature of the cold air. As a result, the temperature of the cold air is lower than the temperature of the cold air when the cool storage material is not stored, and the cold air goes to the occupant.

As described above, the humidifying and cooling air blower for a vehicle according to claim 1 has a merit as a simple cooler for giving a passenger a cool air feeling by the atomized water, and by using the cold storage material, the humidifying air is humidified. The effect of being able to make the temperature of the cold air to be even lower is obtained.

[Means for Claim 2] In the technical means for claim 2, since the condensed water generated in the regenerator unit is guided to the humidifying water tank of the atomizing means, the condensed water introduced to the humidifying water tank is Used as humidifying water. Therefore, it is possible to extend the operation time for blowing out the humidified air. Further, it is possible to eliminate the problem that the condensed water leaks to the outside of the vehicle humidifying cooler.

[Means for Claim 4] By arranging the heater in place of the cool storage material in the cool storage material unit, it is possible to blow warm air toward the occupant from the air outlet. That is,
The vehicle humidifying cool air blower according to claim 4 can blow cold air and warm air.

The ultrasonic transducer 8 is provided.

The air passages 5 of this embodiment are provided independently on the left and right sides so that the air flows generated by the left and right centrifugal fans 6 of the blower 2 are independently guided to the left and right of the head of the occupant. . An air outlet 9 is provided at the downstream end of each air passage 5 to blow out the air that has passed through the air passage 5 toward the head of the occupant located below.

The air passage 5 is divided into a humidified air passage 11 to which the atomized water generated by the atomizing means 3 is supplied and a normal air passage 12 to which the atomized water is not supplied. The air that has passed through the humidified air passage 11 is guided to the central portion of the air outlet 9, and the air that has passed through the normal air passage 12 is guided around it.

At the upstream side of the branch portion between the humidified air passage 11 and the normal air passage 12 in the air passage 5, a regenerator material A (for example, a prismatic container in which the regenerator is enclosed or ice) is used for air flow. A cool storage material unit 13 for cooling the air flowing through the passage 5 is provided.

As shown in FIG. 3, the cool storage material unit 13 includes a storage portion 14 for storing the cool storage material A and a storage portion 1.
4 and a plurality of fins 15 that are integrally provided in the lower portion of the heat storage material 4 and that transfer the cold heat of the regenerator material A to the air flowing through the air passage 5. The storage portion 14 and the fins 15 are made of, for example, aluminum having excellent thermal conductivity, and the regenerator material A stored in the storage portion 14 includes an opening / closing lid 16 provided on the upper part of the main body of the vehicle humidifying / cooling fan 1. It is possible to replace or replenish via the.

Further, the cold storage material unit 13 includes the atomizing means 3
It is arranged further upwind and is provided so that condensed water generated in the fins 15 is guided to the humidification water tank 7 of the atomizing means 3.
Further, a drain port 17 is formed on the bottom of the storage section 14,

As shown in FIG. 1, the partition wall 18 protruding upward from the bottom surface of the upstream end of the air passage 5 is for preventing the water dropped from the cool storage material unit 13 from flowing to the blower 2 side. is there.

As described above, the water (condensed water or water in which ice is melted) dropped from the cold storage material unit 13 is surely guided to the humidifying water tank 7, so that the water dropped from the cold storage material unit 13 is atomized water. As a result, it is possible to prolong the operation time for blowing out the humidified air, and it is possible to eliminate the problem that the water dropped from the regenerator material unit 13 leaks to the outside.

Further, in the storage portion 14 of the cool storage material unit 13, an electric heater (not shown, for example, a PTC heater) which generates heat when energized is provided in place of the cool storage material A. Then, by operating the blower 2 and the electric heater (the atomizing means 3 is in a stopped state), the air passing through the air passage 5 can be heated and hot air can be blown out from the air outlet 9.

[Operation of Embodiment] Next, the operation of the above embodiment will be described. (When the cool storage material A is not stored in the cool storage material unit 13) When a humidification cooling switch (not shown) is turned on, the blower 2 and the atomizing means 3 start operating. The airflow generated by the blower 2 is supplied to the left and right air passages 5 and flows through the humidified air passages 11 and the normal air passages 12, respectively. The airflow flowing through the humidifying air passage 11 is supplied with atomized water from the atomizing means 3 to become humidified air, which is blown out toward the occupant from the center of the air outlet 9. Further, the air flowing through the normal wind passage 12 is blown toward the occupant from the outside inside the outlet 9 as normal wind without being supplied with the atomized water.

The atomized water contained in the humidified wind removes latent heat from the surroundings and evaporates to lower the temperature of the humidified air (The vaporization of the atomized water is performed until immediately before the occupant and reaches the occupant. The temperature of the wind is kept low). The humidified air with the lowered temperature is covered with the normal wind and directed toward the occupant in a spotwise manner, so that the humidified air with the low temperature is prevented from diffusing to the surroundings before reaching the occupant, and the humidified air with the low temperature is Is delivered to the occupant, and the occupant can be given a feeling of cold wind.

(When the regenerator material A is stored in the regenerator material unit 13) When a humidifying and cooling switch (not shown) is turned on, the blower 2 and the atomizing means 3 start operating. On the other hand, storage part 1
The cold heat of the regenerator material A or ice stored in the storage unit 4 is stored in the storage unit 1
It is transmitted to many fins 15 through 4. Therefore, the airflow sent from the blower 2 to the air passage 5 is cooled by exchanging heat with the regenerator material A through the large number of fins 15. Then, the air (cold air) cooled by passing through the fins 15 is supplied to the left and right air passages 5 and flows through the humidified air passages 11 and the normal air passages 12, respectively.

The cold air flowing through the humidified air passage 11 is supplied with atomized water from the atomizing means 3 to become humidified cold air and is blown from the center of the air outlet 9 toward the occupant. Further, the cold air flowing through the normal air passage 12 is blown toward the occupant from the outside of the air outlet 9 as the cold air without being supplied with the atomized water. The atomized water contained in the humidified cold air takes latent heat from the surroundings and evaporates, further lowering the temperature of the humidified cold air. Then, the humidified cold air whose temperature has dropped is covered by the cold air around and is directed toward the occupant in a spotwise manner.
The humidified cold air having a low temperature is prevented from diffusing to the surroundings before reaching the passenger, and the humidified cool air having a low temperature is delivered to the passenger. As a result, it is possible to give the occupant a cooler feeling of cold air than when the cool storage material A is not stored in the cool storage material unit 13.

[Effects of the Embodiment] The humidifying air chiller 1 for a vehicle of this embodiment has a merit as a simple cooler that gives an occupant a cool air sensation by using atomized water. By storing the cool storage material A in the cool storage material unit 13, the temperature of the cold air supplied to the occupant can be further lowered. For this reason, when it is desired to further lower the temperature than the temperature of the cold air generated by the atomized water, it is possible to deal with it by putting the cold storage material A in the cold storage material unit 13.

Further, the vehicle humidifying cooler 1 of this embodiment is
Since it is an integrated package type, it can be easily mounted on a work vehicle such as a forklift. Further, since the vehicle humidifying cooler 1 is mounted on the ceiling, it does not give a feeling of pressure to an occupant and does not disturb the vehicle operation.

FIG. 5 is a sectional view of the cool storage material unit 13. The first of the above
In the cool storage material unit 13 of the embodiment, a container containing a cool storage agent or ice can be used as the cool storage material A.
An example is shown in which the storage portion 14 in which the is arranged and a large number of fins 15 are configured. However, in the second embodiment, only ice is used as the cold storage material A, and a plurality of ice containers 21 for storing ice are provided in the upstream portion of the air passage 5 through the gap 22 through which the air in the air passage 5 passes. It is opened and placed.

Each ice container 21 is made of aluminum or the like having excellent thermal conductivity, and has a drain port 17 at the bottom for dropping melted water. The water dropped from the drain port 17 is provided so as to be guided to the humidifying water tank 7 (see the first embodiment) as shown in the first embodiment. This second
The operation of the embodiment has the same effect as that of the first embodiment by putting ice into the ice container 21 to cool the air passing through the gaps 22 of the ice container 21 by exchanging heat with the ice.
