Description

Technical Field

[0001] This utility model relates to the field of water heater anti-dry burning technology, and in particular to a water heater anti-dry burning device for new energy vehicles. Background Technology

[0002] When the water heater in a new energy vehicle is left unfilled after prolonged use, it may dry-burn, causing damage to the heating element. Furthermore, the increased internal pressure in this state poses a risk of explosion, increasing the safety hazard of the water heater. Since the driver cannot directly observe the heater, they may not be able to detect abnormalities in a timely manner. A patent application published on the Chinese Patent Network, titled "Anti-dry-burning Device for Instantaneous Water Heaters" (application number "201921829136.8"), describes a device that uses a heat-conducting copper sheet to transfer overheating and stabilize the heater, thus providing a power-off command. However, under high-temperature conditions, the power cord may be damaged, affecting the safety of the anti-dry-burning device. Additionally, this device cannot effectively alert the user to abnormal conditions of the water heater during use. Utility Model Content

[0022] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0023] Reference Figure 1-5 This utility model embodiment provides a water heater anti-dry-burning device for new energy vehicles, which includes: a heating box 1, with water inlet pipes 4 on both the left and right surfaces of the heating box 1, a heating mechanism 3 fixedly connected to the front surface of the heating box 1, a groove 2 on the front surface of the heating box 1, the front end of the heating mechanism 3 being located on the inner wall of the groove 2, the heating mechanism 3 being composed of a power supply component and a PTC heating element, the PTC heating element being located inside the heating box 1, and the power supply component being located inside the groove 2, the above components working together to form the basic structure of the water heater.

[0024] Specifically, when using the heater, the water source enters the heating box 1 through two water inlet pipes 4, and the heating mechanism 3 changes the temperature of the water source inside the heating box 1 by electric heating.

[0025] A mounting bracket 10 and a pressure relief pipe 5 are fixedly connected to the upper surface of the heating box 1. A spare water tank 9 is fixedly connected to the upper surface of the mounting bracket 10. A three-way pipe 7 is fixedly connected to the outlet end of the spare water tank 9. The lower end of the three-way pipe 7 is fixedly connected to the pressure relief pipe 5. A pressure valve 6 is fixedly connected between the pressure relief pipe 5 and the three-way pipe 7. The pressure valve 6 is used to prevent the water source inside the spare water tank 9 from flowing into the interior of the heating box 1 under normal conditions. A wind whistle 8 is fixedly connected to the branch pipe at the upper end of the three-way pipe 7 away from the spare water tank 9. The three-way pipe 7 has a Y-shaped structure. The two branch pipes at the upper end of the three-way pipe 7 are both upward inclined. The left branch pipe at the upper end of the three-way pipe 7 is fixedly connected to the outlet end of the spare water tank 9. The right branch pipe at the upper end of the three-way pipe 7 is fixedly connected to the wind whistle 8. The three-way pipe 7 uses its own structure to disperse the gas discharged from the interior of the heating box 1 and the water source added to the interior of the heating box 1.

[0026] Specifically, the water inside the heating box 1 evaporates due to heating, causing the air pressure inside the heating box 1 to continuously rise. The increased air pressure enters the interior of the pressure relief pipe 5 and comes into contact with the pressure valve 6. When the air pressure is too high and exceeds the limit of the pressure valve 6, the pressure valve 6 automatically opens. At the moment the pressure valve 6 opens, the air pressure inside the heating box 1 is discharged through the right branch pipe of the three-way pipe 7. During the process of the air pressure being ejected, the whistle 8 is blown to achieve the purpose of sounding an alarm. Meanwhile, the water inside the backup water tank 9 flows into the interior of the heating box 1 through the left branch pipe of the three-way pipe 7. Since both the left and right branches of the three-way pipe 7 are inclined downwards, the water flowing downwards due to gravity is difficult to flow into the right branch pipe of the three-way pipe 7.

[0027] A hot air limiting component 15 is provided on the upper surface of the mounting bracket 10. The hot air limiting component 15 is located above the three-way pipe 7. The hot air limiting component 15 consists of a vertical plate 11, a protective cover 13, and a water-absorbing cotton pad 14. The vertical plate 11 is penetrated by the outlet end of the spare water tank 9. The protective cover 13 is located above the three-way pipe 7. The vertical plate 11 is fixedly connected to the mounting bracket 10. The protective cover 13 is slidably connected to the vertical plate 11. The water-absorbing cotton pad 14 is located inside the protective cover 13 and is fixedly connected to the inner wall of the protective cover 13. The sliding part of the protective cover 13 penetrates the upper surface of the vertical plate 11. The inner wall of the protective cover 13 has an arc structure. The hot air limiting component 15 is used to limit the transmission range of hot air ejected from the right branch of the three-way pipe 7. The water-absorbing cotton pad 14 does not protrude from the lower surface of the protective cover 13. A support rod 12 is fixedly connected to the rear end of the protective cover 13. The lower end of the support rod 12 is engaged with the heating box 1. The support rod 12 improves the stability of the protective cover 13 when it is in operation.

[0028] Specifically, the hot air inside the heating box 1 is discharged through the right branch of the three-way pipe 7 and directly collides with the absorbent cotton pad 14. The moisture carried by the hot air is directly absorbed by the absorbent cotton pad 14. When the absorbent cotton pad 14 needs to be dried, the protective cover 13 can be manually lifted to separate the protective cover 13 from the vertical plate 11, thus providing the staff with sufficient operating space to disassemble and replace the absorbent cotton pad 14.

[0029] Working principle: When the total amount of water inside the heating box 1 decreases due to evaporation and is not replenished in time, the continuously rising air pressure comes into contact with the air pressure valve 6 through the pressure relief pipe 5. When the air pressure inside the heating box 1 exceeds the limit of the air pressure valve 6, the air pressure valve 6 opens, and the air pressure inside the heating box 1 is directly discharged through the right branch of the three-way pipe 7. During the discharge process, it comes into contact with the bagpipe 8, thereby achieving the purpose of blowing the bagpipe 8. After the air pressure valve 6 opens, the water in the backup water tank 9 enters the interior of the heating box 1 through the left branch of the three-way pipe 7, thereby replenishing the water supply to the heating box 1 and preventing the heating box 1 from burning dry.

[0030] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
