Description

car water heater

The utility model relates to a device which is arranged in the engine compartment of an automobile to provide drivers and passengers with drinking hot water.

During long-distance driving, especially in sparsely populated areas, it is extremely inconvenient for drivers and passengers to drink hot water.

The purpose of this utility model is to provide an automobile water heater which utilizes the heat energy carried by the engine coolant and is supplemented by an electric heating device to heat cold water, so as to provide drinking hot water for drivers and passengers.

The technical solution to achieve the above object is: a car water heater, which has a water tank arranged in the engine room, in which a heating tube connected in series with the high-temperature circulating coolant pipeline of the engine and connected with the car power supply and the ignition switch are arranged. An electric heating rod that is electrically connected and configured with a temperature control switch is equipped with a water outlet pipe configured with a water pump, a water filling port and a safety exhaust valve on the top of the water tank.

The technical scheme of the utility model also includes: a water level control power switch connected in series with the ignition switch of the automobile is arranged in the sealing cover of the water inlet, and a bowl-shaped sealing rubber pad is arranged below the switch, which is configured with the rubber pad There is a connecting rod float installed on the filter screen barrel of the water filling port.

The utility model fully utilizes the residual heat of the automobile engine to heat the drinking water, and has good energy-saving effect; the electric heating link can quickly provide boiled water, and is an automobile water heater with simple structure, convenient configuration, high efficiency and energy saving.

Accompanying drawing 1 is this automobile water heater structural representation;

Fig. 2 is its water inlet sectional view;

Figure 3 is a diagram of the electric heating control circuit.

Below in conjunction with accompanying drawing and embodiment the utility model is further described:

Provided as accompanying drawing 1, this automobile water heater has a water tank 1 that is arranged in the engine room, is provided with the heating tube 2 that is connected in series in the engine high-temperature circulating coolant pipeline and is connected with the automobile power supply E and the ignition switch K in the water tank. ₀ is electrically connected and equipped with an electric heating rod 3 with a temperature control switch K _6t , and a water outlet pipe 4 equipped with a water pump M, a water filling port 5 and a safety exhaust valve 6 are installed on the top of the water tank. The heating pipe 2 in the above structure can be designed as a ring, and the lead-out pipes at both ends are connected in series in the engine coolant circulation pipeline. The low-temperature drinking water in the water tank can be heated by absorbing the heat of the coolant flowing through the heating pipe. Purpose. Its outlet pipe 4 is introduced into the cab as a hot water intake. The purpose that safety exhaust valve 6 is provided with is when steam in the water tank reaches a certain amount, discharges water vapor, to prevent water tank from bursting.

As shown in Figure 2, the water heater is provided with a water level control power switch K ₁ connected in series behind the ignition switch K ₀ in the sealing cover 7 of the water inlet, and a bowl-shaped sealing rubber pad 8 is provided below the switch K ₁ , and the rubber pad 8 is configured with a connecting rod float 10 that is mounted on the filter screen barrel 9 of the water filling port. When the water level in the water tank 1 is higher than the electric heating rod, the float rises, causing the bowl-shaped sealing rubber pad to deform upward, driving the water level control power switch K ₁ to connect the electric heating circuit; otherwise, when the water level is lower than the electric heating rod, the electric heating circuit is cut off Open to prevent dry burning. On the one hand, the filter bucket assembled in the water inlet prevents sundries from falling into it when adding water, and on the other hand, solid purifiers, magnetized stones, mineral fossils, tea leaves and other items can be put into the bucket to improve water quality.

When the automobile water heater needs to quickly provide high-temperature boiled water, the electric heating circuit can be started. Its electric heating circuit is shown in Figure 3: the car power supply E and ignition switch K ₀ connected in series form the circuit power supply, and the normally-off temperature switch K _7t , resistor R ₂ and light-emitting diode D ₂ are connected in parallel on it. The temperature switch K _7t is assembled outside the bottom of the water tank 1. When the water temperature in the water tank reaches 80°, the K _7t is turned on, and the light-emitting diode D ₂ lights up, indicating that the water temperature has reached above 80°. The water level control power switch K ₁ is connected in series behind the ignition switch K ₀ , and the low water level conduction contact of the switch and the negative pole of the power supply are connected in parallel with a series resistor R ₁ and a light-emitting diode D ₁ , when the water level in the water tank is lower than the electric heating rod When the circuit is turned on, the diode _D1 lights up, indicating that the water level is too low, and water should be added to the water tank. The water pump M and the water supply button _K2 are connected in series and connected between the high water level conduction contact of the switch _K1 and the negative pole of the power supply E. A relay JTX is connected in series behind the high water level conduction contact of the switch _K1 , and a non-blocking long-off button switch _K4 is connected between the conduction contacts of the relay relay switch _K3J . The negative poles of the power supply E are respectively connected in parallel with series resistors R ₃ and D ₃ , series connected relay electromagnetic coil L _J and normally on temperature control switch K _5t , series connected normally on temperature control switch K _6t and electric heating rod heating wire R _4T . When the water level control switch K ₁ is in the high water level conduction state, press the switch K ₄ , the electromagnetic coil L _J obtains voltage and generates electromagnetic force to attract and lock the relay switch K _3J , the heating wire is energized to generate heat, and the electric heating rod is used to generate heat. The water in the water tank is heated, and the light-emitting diode D ₃ lights up at this time, indicating that the water heater is in the state of electric heating; when the water temperature reaches 100°, the normally-on temperature control switches K _5t and K _6t installed outside the bottom of the water tank are disconnected by temperature control, After K _5t is disconnected, the electromagnetic coil L _J loses power, the magnetic force disappears, and the relay switch K _3J is released, causing the heating wire R _4T to lose power and stop heating, and the disconnection of K _6t will directly cut off the heating wire R _4t circuit. Take it off the heat. The settings of K _5t and K _6t constitute automatic temperature control of electric heating with double insurance.
