Description

The automobile water heater

The utility model relates to a kind of indoor device that drinking hot water is provided for chaufeur and occupant of car engine that is arranged on.

In long-distance driving process, particularly in the sparse area of human footmarks, chaufeur and occupant's drinking hot water be inconvenience very.

The purpose of this utility model provides a kind ofly to be utilized the entrained heat energy of engine coolant and is aided with electric heater unit heating cold water, thereby the automobile water heater of drinking hot water is provided for chaufeur and occupant.

The technical scheme that realizes above-mentioned purpose is: a kind of automobile water heater, it has a water tank that is arranged in the engine room, in this water tank, be provided with the heating pipe that is serially connected with in the engine high-temperature circulation cooling liquid pipeline and be electrically connected and dispose the electrical bar of coolant-temperature switch, on water tank, be equipped with coolant outlet pipe, filler and the safety exhaust of configuration water pump with automobile power source and ignition lock.

The technical solution of the utility model also comprises: be provided with the water level control source switch that is serially connected on the automobile ignition switch in the seal cover cap of filler, the below of its switch is provided with the sealing rubber pad of a bowl-type, and matching with this rubber pad is equipped with a connecting rod float that is installed on the filtering net bucket of filler.

The waste heat that the utility model makes full use of automotive engine heats potable water, has good energy-saving effect; Configuration electro heat link can provide boiling water fast, is a kind of simple in structure, automobile water heater that configuration is convenient, energy-efficient.

Accompanying drawing 1 is this automobile water heater structural representation;

Fig. 2 is its filler cutaway view;

Fig. 3 is electro heat control circuit figure.

The utility model is described in further detail below in conjunction with drawings and Examples:

Provide as accompanying drawing 1, this automobile water heater has a water tank 1 that is arranged in the engine room, in water tank, be provided with the heating pipe 2 that is serially connected with in the engine high-temperature circulation cooling liquid pipeline and with automobile power source E and ignition lock K ₀Be electrically connected and configuration coolant-temperature switch K _6tElectrical bar 3, on water tank, be equipped with coolant outlet pipe 4, filler 5 and the safety exhaust 6 of configuration water pump M.Heating pipe 2 in the said structure can be designed to annular, is serially connected in the engine coolant circulation line by the fairlead at two ends, and the low temperature potable water in its water tank reaches the purpose of heating by the flow through heat of refrigerant fluid of heating pipe of absorption.Its coolant outlet pipe 4 is introduced in the operator's compartment, gets mouth as hot water.The purpose that safety exhaust 6 is provided with is that when steam in the water tank reaches a certain amount of discharge water steam is to prevent the explosion of water case.

Provide as accompanying drawing 2, this water heater is provided with in the seal cover cap 7 of filler and is serially connected in ignition lock K ₀Water level control source switch K afterwards ₁, its K switch ₁The below be provided with a bowl-type sealing rubber pad 8, matching with rubber pad 8 is equipped with a connecting rod float 10 that is installed on the filler filtering net bucket 9.When the water level in the water tank 1 was higher than electrical bar, float rose, and made the upwards distortion of bowl-type sealing rubber pad, drove water level control source switch K ₁Connect electric heating circuit; Otherwise when water level was lower than electrical bar, electric heating circuit disconnected, and prevents dry combustion method.Fall into foreign material when the filtering net bucket that assembles in its filler prevents to add water on the one hand, can in this bucket, put into article such as solid purificant, magnetization stone, mineralizing stone, tealeaves on the other hand, be used to improve water quality.

When this automobile water heater provides the high temperature boiling water fast at needs, can start electric heating circuit.Its electric heating circuit provides as accompanying drawing 3: the automobile power source E of serial connection and ignition lock K ₀The forming circuit power supply, thereon and meet series connected normal off temperature switch K _7t, resistance R ₂With light-emitting diode D ₂, its temperature switch K _7tBe assemblied in water tank 1 bottom outside, K when water temperature in the water tank reaches 80 ° _7tConducting, light-emitting diode D ₂Light, indicating water temperature has reached more than 80 °.Water level control source switch K ₁Be serially connected in ignition lock K ₀Afterwards, between the low water conducting contact of its switch and the power cathode and connect series connected resistance R ₁With light-emitting diode D ₁, when water level is lower than electrical bar in the water tank, this loop conducting, diode D ₁Light, indicated water level is low excessively, should add water in water tank.Its water pump M and water supply button K ₂Be attempted by K switch after the series connection ₁Between high water level conducting contact and the power supply E negative pole.In K switch ₁The back of high water level conducting contact is serially connected with relay J TX, at relay relay switch K _3JThe conducting contact between and be connected to the long disconnected button switch K of not locking ₄, between the negative pole of relay conducting contact and power supply E respectively and connect series connected resistance R ₃And D ₃, series connected electromagnetic coil relay L _JWith normal open coolant-temperature switch K _5t, series connected normal open coolant-temperature switch K _6tWith electrical bar heater strip R _4TAt level control switch for water K ₁Be under the high water level conducting state Push switch K ₄, magnet coil L _JObtain voltage and produce electromagnetic force relay switch K _3JAdhesive is also pinned, and the heater strip heating power is by water heating, light-emitting diode D at this moment in the electrical bar feed-tank ₃Light, the indication water heater is in the electro heat state; When water temperature reaches 100 °, be installed in the normal open coolant-temperature switch K in the water tank bottom outside _5tAnd K _6tDisconnected by temperature control, its K _5tMake magnet coil L after the disconnection _JLose power supply, magnetic force disappears, relay switch K _3JDischarge, cause heater strip R _4TLose power supply and stop heating, and K _6tDisconnection will directly cut off heater strip R _4tCircuit makes it stop heating.Its K _5t, K _6tBe provided with and constitute double insurance electro heat temperature automatic guidance.
