The present invention relates to a combustion auxiliary heater for a vehicle, and more particularly, a vehicle lead that enables a vehicle user to check an appropriate amount of cooling water in a combustion auxiliary heater and additionally check whether the cooling water flows normally. It is about news auxiliary heater.

The air conditioning system of a vehicle is composed of a ventilation system for ventilation in the cabin and a cooling and heating system for performing air conditioning in the cabin.

In particular, a heating system that is frequently used in low temperature outdoor air, etc., is typically used to circulate the engine while the heated cooling water flows into the heater to heat the heater core, and the heat of the heater core is blown by the blower into the cabin. Inflow structure is made.

However, in recent years, due to the emergence of multi-seater vehicles and commercialization of diesel engines, it is difficult to expect satisfactory heater performance depending on the heat generation of the engine itself.

In view of this, efforts have been made to improve heating performance by adding an auxiliary heater, and among them, a combustion auxiliary heater is most adopted.

1 is a block diagram schematically illustrating a system of an auxiliary heating device employing a combustion auxiliary heater, in which a combustion auxiliary heater 1 is connected to a coolant hose 4 between an engine 2 and a heater core 3. It is connected by media.

When the engine 2 is operated, an electronic control unit (ECU; not shown) of the vehicle controls the outside air temperature and the coolant temperature. At this time, when the combustion auxiliary heater 1 is operated under appropriate conditions, the engine 2 is installed in the engine 2. The coolant is circulated by the water pump 5, which flows to the combustion auxiliary heater 1 through the cooling water hose 4, and the coolant flows to a proper temperature in the combustion auxiliary heater 1. It is heated to and sent to the heater core (3) to the heating for the vehicle interior and the defrosting for the windows.

However, since the system shown in FIG. 1 does not operate when the engine is not driven, when the heating is required during parking, the engine must be operated inevitably, resulting in waste of energy and pollution due to fuel consumption and smoke generation. There was a problem.

Recently, in order to improve heating performance in a vehicle even when the winter engine is not operated, a separate auxiliary water pump for forcibly circulating the coolant and an air discharge valve for bleeding air present in the coolant are installed. .

However, when the cooling water is evaporated by the heat of the combustion auxiliary heater and the proper amount thereof is insufficient, the related art as described above has no method for the vehicle driver to confirm this.

The present invention has been created to solve the above problems, vehicle combustion type to enable the vehicle user to check the appropriate amount of the coolant amount in the combustion auxiliary heater and additionally check whether the coolant flows normally. It is an object to provide an auxiliary heater.

The present invention for achieving the above object is to heat the cooling water flowing along the cooling water flow path formed inside the auxiliary heater body to discharge the cooling water introduced from the engine to the heater core side by using the heat generated by the combustion means The combustion auxiliary heater for a vehicle, wherein the cooling water amount display means for displaying the amount of cooling water in the cooling water flow path is provided at an upper portion of the auxiliary heater body.

Hereinafter, a preferred embodiment of a combustion auxiliary heater for a vehicle according to the present invention will be described in detail with reference to the accompanying drawings.

2 is a view showing a configuration of a combustion auxiliary heater for a vehicle according to the present invention, Figure 3 is a cross-sectional view showing a state in which the buoyancy member of the present invention is lowered due to lack of cooling water.

The present invention heats the cooling water flowing along the cooling water flow path 120 formed inside the auxiliary heater body 110 to discharge the cooling water introduced from the engine to the heater core side by using the heat generated by the combustion means 150. In the combustion type auxiliary heater 100 for a vehicle, the coolant amount display means 200 for displaying the amount of coolant in the coolant flow path 120 is installed above the auxiliary heater body 110.

Here, the combustion auxiliary heater 100 is a conventional technology, detailed description thereof will be omitted.

The cooling water amount display means 200 is composed of a fastening portion 210, the display member 220, the buoyancy member 230, and the separation preventing means 240.

The fastening part 210 is provided with a communication hole 211 therein so that the cooling water flow path 120 is in communication with the outside, it is formed protruding on the upper portion of the auxiliary heater body (110).

The display member 220 is detachably coupled to the fastening part 210, and a cooling water amount display scale 221 is formed on the outer surface at a predetermined interval up and down, and the lifting guide hole 222 vertically penetrated therein ) Is formed of a transparent material.

Here, the display member 220 and the fastening portion 210 are typically detachably coupled by a screw coupling method.

The buoyancy member 230, a lower portion of the lower portion is located in the cooling water flow path 120, the upper portion is inserted into the elevating guide hole 222 to be lowered, the elevating guide hole by the buoyancy of the coolant ( 222 is moved up and down.

The detachment preventing means 240 serves to prevent the buoyancy member 230 from being separated in the lifting guide hole 222.

The separation preventing means 240 is formed to be bent at the upper end of the buoyancy member 230, the bent portion 241 and the lower inner surface of the elevating guide hole 222 of the display member 230 is It consists of a locking step 242 to be bent 241.

Here, when the buoyancy member 230 is maximally lowered due to lack of cooling water in the cooling water flow path 120, the bent portion 241 is caught by the locking jaw 242.

On the other hand, the present invention is provided with a cap member 250 for sealing the upper opening of the display member 220.

Here, when the cap member 250 is designed to further extend the height of the display member 230 and the vertical length of the elevating guide hole 222, the coolant overflows to the outside through the elevating guide hole 222. There is no fear, but it is necessary to close the upper opening of the display member 230 in case the coolant overflows.

Here, reference numeral 160 serves as an inlet pipe to receive the cooling water sent from the engine into the cooling water flow path 120.

In addition, reference numeral 170 serves to allow the cooling water heated by the combustion means 150 to be sent back to the heater core (not shown) as an outnet pipe.

Referring to the operation of the present invention as described above are as follows.

As shown in FIG. 2, when the coolant is filled in the coolant flow path 120, the buoyancy member 230 is lifted by the buoyancy force of the coolant to be raised from the lifting guide hole 222.

In this state, the user can confirm that the upper end of the buoyancy member 230 is positioned through the display member 220 made of a transparent material, so that the coolant is filled in the coolant flow path 120.

Here, when the height of the elevating guide hole 222 is changed higher by changing the height of the buoyancy member 230, when the coolant flows in the coolant flow path 120, the buoyancy member 230 is a fine up and down guide hole ( Moving up and down within 222 can be confirmed through the display member 220.

Thus, by looking at the movement of the buoyancy member 230, it can be visually confirmed whether the cooling water is normally flowing.

On the other hand, when the coolant is insufficient in the coolant flow path 120, as shown in Figure 3, the buoyancy member 230 is lowered in the lifting guide hole 222.

Therefore, the user can see the scale of the display member 220, the upper end of the buoyancy member 230, it is possible to know how much the coolant is insufficient, as a result it is possible to replenish the coolant through the coolant inlet of the radiator of the vehicle will be.

As described above, according to the present invention, the vehicle user can check the proper amount of the cooling water amount in the combustion auxiliary heater, and additionally, it is possible to check whether the cooling water flows normally.
