Description

Technical Field

[0001] The utility model relates to the technical field of gas water heaters, in particular to a vehicle-mounted water heater capable of adjusting the combustion condition. Background Art

[0002] A vehicle-mounted water heater is a portable device, usually installed inside a recreational vehicle, aiming to provide convenient hot water services for drivers and passengers.

During long-term outdoor camping, self-driving tourism and other activities, the vehicle-mounted water heater can provide people with hot water for bathing or cleaning, so as to provide continuous and convenient hot water services.

[0003] During a long journey, people will inevitably pass through high-altitude areas or low-altitude areas. The existing vehicle-mounted water heaters on the market cannot adjust the combustion mode according to the altitude requirements. For some vehicle-mounted water heaters suitable for low-altitude areas, due to the relatively low boiling point of water and the small air pressure value in high-altitude areas, if such vehicle-mounted water heaters suitable for low-altitude areas are used in high-altitude areas, it will cause the gas to not be fully burned, seriously wasting energy. On the contrary, there are also some vehicle-mounted water heaters suitable for high-altitude areas. If such vehicle-mounted water heaters suitable for high-altitude areas are used in low-altitude areas, it will lead to too high combustion efficiency, overheating of the vehicle-mounted water heater or other adverse consequences.

[0004] The present utility model is studied and proposed in view of the deficiencies of the prior art. Summary of the Utility Model

[0005] In view of the problem that the existing vehicle-mounted water heaters mentioned above cannot adjust the combustion mode according to the altitude environment requirements, resulting in energy waste or easy damage to the equipment, the technical solution adopted by the present utility model to solve its technical problems is as follows:

[0006] A vehicle-mounted water heater capable of adjusting the combustion condition includes a water heater housing, the water heater housing includes a front panel and a rear cover body, the front panel and the rear cover body enclose to form an installation cavity, and a burner assembly, a gas supply assembly for supplying gas to the burner assembly and connected to the burner assembly, a fan assembly for driving air to flow to the burner assembly, and a control device for simultaneously controlling the working states of the gas supply assembly and the fan assembly are arranged on the installation cavity.

[0007] Furthermore, the control device includes a main control component located on the installation cavity and a remote controller located outside the water heater housing and electrically connected to the main control component. The signal output end of the main control component is respectively connected to the signal input end of the gas supply assembly and the signal input end of the fan assembly.

[0008] Further, the gas supply component includes a gas distribution rod component, a gas proportional valve connected to the main control component and used to control the amount of gas entering the burner component, and an air inlet joint located on one side of the gas proportional valve and connected to the gas proportional valve. The gas proportional valve is connected to the burner component through the gas distribution rod component.

[0009] Further, the burner component includes a burner main body connected to the gas distribution rod component to obtain gas. The burner main body is composed of a plurality of burner monomers. Gas delivery holes corresponding to each burner monomer are arranged at intervals on one side of the gas distribution rod component close to the burner monomers.

[0010] Further, the burner component further includes a heat exchanger located above the burner monomer and connected to the burner monomer to convert heat for heating water.

[0011] Further, the fan component includes a fan main body connected to the main control component to control the rotation speed, and a smoke collecting hood located above the fan main body and communicating with the top of the burner component. One end of the fan main body penetrates through the smoke collecting hood, and an air circulation hole is arranged on one side of the burner component.

[0012] Further, a windproof and smoke guiding device is arranged on one side of the installation cavity close to the panel. The smoke collecting hood is communicated with the windproof and smoke guiding device to discharge the smoke to the outside.

[0013] Further, the windproof and smoke guiding device is provided with a smoke guiding channel for guiding the smoke to the outside and a wind shielding space for preventing the outside wind from driving the smoke back into the burner component.

[0015] Further, the wire controller includes an on / off button, a Fahrenheit / Celsius unit conversion button, and a high / low altitude mode conversion button.

[0016] The beneficial effects of the present utility model are as follows:

[0017] 1. An in-vehicle water heater capable of adjusting the combustion condition according to the present utility model is provided with a gas supply component on the installation cavity for supplying gas to the burner assembly and a fan assembly for driving air to flow into the burner assembly. When a user transfers from a low-altitude area to a high-altitude area, the user can control the gas supply component to reduce the gas amount in the burner assembly and control the fan assembly to increase the rotation speed through the touch control device, so that air can quickly enter the burner assembly to fully burn with the gas. Conversely, when the user transfers from a high-altitude area to a low-altitude area, the touch control device is used to increase the gas amount in the burner assembly and reduce the rotation speed of the fan assembly, thereby increasing the heat load of the in-vehicle water heater. The in-vehicle water heater can adjust the setting of the combustion mode according to the altitude environment requirements, avoiding the situation of energy waste caused by incomplete gas combustion, and effectively solving the problems that the existing in-vehicle water heaters cannot adjust the combustion mode according to the altitude environment requirements, resulting in energy waste or easy damage to the equipment.

[0018] 2. By setting the fan body, the smoke collecting hood and the wind-proof smoke guiding device to cooperate with each other, the smoke generated by the burner assembly burning gas is discharged to the outside through the smoke guiding channel in the wind-proof smoke guiding device. Secondly, a wind shielding space is provided on the wind-proof smoke guiding device, and the external wind flows back to the outside after entering the wind shielding space, effectively avoiding the situation that the external wind drives the smoke to flow back into the burner assembly, which is beneficial to improving the stability of the device during use.

[0031] The following will describe in detail the implementation manner of the present utility model with reference to the accompanying drawings.

[0032] Such as Figures 1 to 11 A vehicle-mounted water heater capable of adjusting the combustion condition, including a water heater housing 1. The water heater housing 1 includes a front panel 11 and a rear cover body 12. The front panel 11 and the rear cover body 12 enclose to form an installation cavity 13. A burner assembly 4, a gas supply assembly 5 for supplying gas to the burner assembly 4 and connected to the burner assembly 4, a fan assembly 6 for driving air to flow to the burner assembly 4, and a control device 7 for simultaneously controlling the working states of the gas supply assembly 5 and the fan assembly 6 are provided on the installation cavity 13;

[0033] For a vehicle-mounted water heater capable of adjusting the combustion condition of the present utility model, by providing a gas supply assembly capable of supplying gas to the burner assembly and a fan assembly for driving air to flow into the burner assembly on the installation cavity, when the user transfers from a low altitude area to a high altitude area, the user can touch the control device, and the control device controls the gas supply assembly to reduce the gas amount in the burner assembly and controls the fan assembly to increase the rotation speed, so that air can quickly enter the burner assembly and fully burn with the gas. On the contrary, when the user transfers from a high altitude to a low altitude area, by touching the control device, the gas supply assembly increases the gas amount in the burner assembly and reduces the rotation speed of the fan assembly, thereby increasing the heat load of the vehicle-mounted water heater. The vehicle-mounted water heater can adjust the setting of the combustion mode according to the altitude environment requirements, avoiding the occurrence of energy waste caused by incomplete gas combustion, and effectively solving the problems that the existing vehicle-mounted water heaters cannot adjust the combustion mode according to the altitude environment requirements, resulting in energy waste or easy damage to the equipment.

[0034] Such as Figures 1 to 11The control device 7 shown includes a main control component 71 located on the installation cavity 13, and a remote controller 72 located outside the water heater housing 1 and electrically connected to the main control component 71. The signal output end of the main control component 71 is respectively connected to the signal input ends of the gas supply component 5 and the fan component 6;

[0035] Specifically, the remote controller 72 is fixedly arranged in the bathroom, and the water heater housing 1 is arranged outside the bathroom, so that the user can adjust and control the combustion mode without approaching the vehicle-mounted water heater, which provides convenience and reduces the risk of danger caused by the user accidentally touching the vehicle-mounted water heater, and is beneficial to improving safety.

[0036] Furthermore, the remote controller 72 is electrically connected to the main control component 71. The signal output end of the main control component 71 is respectively connected to the signal input ends of the gas supply component 5 and the fan component 6. When the user needs to adjust the combustion mode of the vehicle-mounted water heater, the user touches the remote controller 72, and the remote controller 72 sends an instruction to the main control component 71. After receiving the instruction, the main control component 71 adjusts the opening and closing size of the gas supply component 5 and the rotation speed of the fan component 6, so as to change the combustion working condition of the vehicle-mounted water heater to meet the use requirements at different altitudes.

[0037] Furthermore, the user adjusts the combustion working condition of the vehicle-mounted water heater by touching the remote controller 72. Compared with the automatic adjustment of the system, manual adjustment allows the user to select the combustion mode according to the actual situation and personal preference, increasing the user's control over the device; secondly, in some specific situations, the system may not be able to accurately sense the environmental parameters or user needs completely, while manual adjustment allows the user to make flexible adjustments according to the actual situation, effectively improving the adaptability of the device.

[0038] It should be noted that the principle that the remote controller 72 sends an instruction to the main control component 71 so that the main control component 71 can control the opening and closing size of the gas supply component 5 and the rotation speed of the fan component 6 is prior art.

[0039] As Figures 1 to 11 The gas supply component 5 shown includes a gas distribution rod assembly 51, a gas proportional valve 52 connected to the main control component 71 and used to control the gas volume entering the burner assembly 4, and an air inlet joint 53 located on one side of the gas proportional valve 52 and connected to the gas proportional valve 52. The gas proportional valve 52 is connected to the burner assembly 4 through the gas distribution rod assembly 51;

[0040] Further, by setting the gas proportion valve 52 to control the amount of gas entering the burner assembly, precise adjustment of the gas amount can be achieved. The gas proportion valve 52 adjusts the opening and closing size to ensure the gas amount obtained by the burner assembly 4, thereby achieving the stability and efficiency of combustion.

[0041] Specifically, the air intake joint 53 obtains gas from the outside. The gas enters the gas proportion valve 52, and the gas in the gas proportion valve 52 enters the burner assembly 4 through the gas distribution rod assembly 51 for the burner assembly 4 to burn.

[0042] As Figures 1 to 11 shown, the burner assembly 4 includes a burner main body 41 connected to the gas distribution rod assembly 51 to obtain gas. The burner main body 41 is composed of a plurality of burner units 411. The gas distribution rod assembly 51 is provided with gas delivery holes 511 corresponding to each burner unit 411 at intervals on the side close to the burner unit 411.

[0043] Further, by arranging the gas delivery holes 511 at intervals on the side of the gas distribution rod assembly 51 close to the burner unit 411, uniform distribution of the gas supply to each burner unit 411 can be achieved, effectively ensuring that each burner unit 411 can obtain the same gas amount, thereby achieving the uniformity and stability of combustion.

[0044] Further, by uniformly supplying gas through the gas distribution rod assembly 51, the situation of incomplete combustion caused by insufficient or excessive gas supply to some burner units 411 can be effectively avoided, thereby improving the combustion efficiency, reducing the emission of harmful gases, and at the same time extending the service life of the burner.

[0045] Further, each burner unit 411 has an independent gas delivery hole corresponding and cooperating. Once a problem occurs in a certain burner unit 411, it will not affect the normal operation of other burner units 411, thereby improving the overall safety performance.

[0046] Further, by arranging several burner units 411 corresponding and cooperating with the gas delivery holes 511, local overheating of the device can be reduced, and the service life of the burner assembly 4 can be extended.

[0047] As Figures 1 to 11 shown, the burner assembly 4 further includes a heat exchanger 42 located above the burner unit 411 and connected to the burner unit 411 to convert heat for water heating.

[0048] Specifically, the heat exchanger 42 includes a combustion chamber 421 located above each burner unit 411, a heat exchange coil 422 located above the combustion chamber 421, and heat exchange fins 423 sleeved on the outer side wall of the heat exchange coil 422.

[0049] Furthermore, fuel gas and air are combusted in cooperation in the combustion chamber 421, and the generated heat adheres to the heat exchange fins 423. The heat exchange fins 423 wrap the heat exchange coil 422 so that the heat exchange coil 422 can obtain heat through the heat exchange fins 423, thereby heating water.

[0050] As Figures 1 to 11 shown, the blower assembly 6 includes a blower main body 61 connected to the main control assembly 71 to control the rotation speed, and a smoke collecting hood 62 located above the blower main body 61 and communicating with the top of the burner assembly 4. One end of the blower main body 61 penetrates through the smoke collecting hood 62, and an air circulation hole 43 is provided on one side of the burner assembly 4;

[0051] Furthermore, the signal input end of the blower assembly 6 is connected to the signal output end of the main control assembly 71 so that the main control assembly 71 can control the rotation speed of the blower main body 61.

[0052] Specifically, when the user needs to adjust the combustion condition of the in-vehicle water heater, the user touches the wire controller 72. The wire controller 72 transmits an instruction to the main control assembly 71. The main control assembly 71 controls the rotation speed of the blower main body 61. The smoke collecting hood 62 communicates with the top of the burner assembly 4. When the fuel gas is combusted in the combustion chamber 421, the generated flue gas enters the smoke collecting hood 62. One end of the blower main body 61 penetrates through the smoke collecting hood. When the blower main body 61 rotates, one end of the blower main body 61 located in the smoke collecting hood 62 rotates to form a negative pressure, accelerating the entry of the flue gas in the burner assembly 4 into the smoke collecting hood 62 so that external air can enter the combustion chamber 421 through the air circulation hole 43 for combustion in the combustion chamber 421.

[0053] As Figures 1 to 11 shown, a windproof and smoke guiding device 8 is provided on one side of the installation cavity 13 close to the panel 11. The smoke collecting hood 62 communicates with the windproof and smoke guiding device 8 to discharge the flue gas to the outside;

[0054] Furthermore, by providing the windproof and smoke guiding device 8 communicating with the smoke collecting hood 62, the flue gas generated when the fuel gas is combusted in the combustion chamber 421 enters the smoke collecting hood 62, and then the flue gas is discharged to the external environment through the windproof and smoke guiding device 8, which is beneficial to improving the working stability of the burner assembly 4.

[0055] Furthermore, by providing the windproof and smoke guiding device 8, it can also prevent external wind from entering the device interior, thereby preventing the situation where the flue gas is backflowed into the burner assembly 4.

[0056] As Figures 1 to 11 shown, the windproof and smoke guiding device 8 is provided with a smoke guiding channel 81 for guiding the flue gas to be discharged to the outside and a wind shielding space 82 for preventing the external wind from driving the flue gas to backflow into the burner assembly 4;

[0057] Specifically, inside the windproof smoke guiding device 8, there is a smoke guiding plate and a wind shielding plate. The smoke guiding plate is located between the smoke inlets on the side of the windproof smoke guiding device 8 close to the smoke collecting hood 62. The wind shielding plate is located below the smoke guiding plate, and the upper end surface of the wind shielding plate close to the smoke guiding plate is located at the bottom of the smoke inlet. A smoke guiding channel 81 is formed between the smoke guiding plate and the inner side wall of the top of the windproof smoke guiding device, and a smoke guiding channel 81 is also formed between the smoke guiding plate and the wind shielding plate. The wind shielding plate is in a "C" shape with an opening facing the outside of the device, and the opening in the middle of the wind shielding plate is a wind shielding space 82.

[0058] Furthermore, the setting of the double smoke guiding channels 81 is beneficial for diverting the smoke, making the flow of the smoke more uniform, reducing the resistance of the smoke during the smoke exhaust process, and effectively improving the smoothness of the smoke exhaust.

[0059] Furthermore, the setting of the wind shielding space 82 can cause the external wind to form a backflow in the wind shielding space 82, thereby driving the smoke to be smoothly discharged to the outside. The smoke is discharged to the outside through the smoke exhaust port, effectively improving the stability of the smoke exhaust.

[0060] As Figures 1 to 11 shown, the main control component 71 is arranged on the side close to the panel 11, and the gas supply component 5 and the burner component 4 are both arranged on the side far from the panel 11;

[0061] Furthermore, by arranging the main control component 71 on the side close to the panel 11 and the gas supply component 5 and the burner component 4 on the side far from the panel 11, it helps to separate the main control device from the combustion device, reduces the influence of the combustion device on the main control device, is beneficial for reducing the safety risks caused by combustion device failures or operation mistakes, and effectively improves the safety of the system.

[0062] Furthermore, by separately arranging the main control component 71 from the gas supply component 5 and the burner component 4, the electromagnetic interference or thermal interference of the burner component 4 on the main control device can be reduced, thereby ensuring the stable operation of the main control device and effectively improving the reliability and stability of the system.

[0063] As Figures 1 to 11 shown, the wire controller 72 includes an on / off button, a Fahrenheit / Celsius unit conversion button, and a high / low altitude mode conversion button;

[0064] Furthermore, the wire controller 72 provides heating and cooling function modes, so that users can adjust the temperature of the system according to needs and achieve precise adjustment of temperature control.

[0065] Furthermore, the wire controller 72 supports the Fahrenheit and Celsius unit conversion function, so that users can choose the temperature display unit according to their own habits, which is beneficial for improving the flexibility and applicability of use.

[0066] Further, the remote controller 72 provides a high / low altitude mode conversion function, which can be adjusted according to the actual altitude to ensure the normal operation of the system in different altitude environments, and is beneficial to improving the adaptability and stability of the system.

[0067] The implementation manner of this embodiment is as follows:

[0068] A vehicle-mounted water heater capable of adjusting the combustion condition includes a water heater housing 1. The water heater housing 1 includes a front panel 11 and a rear cover body 12. The front panel 11 and the rear cover body 12 enclose to form an installation cavity 13. A burner assembly 4, a gas supply assembly 5, a blower assembly 6 and a control device 7 are provided on the installation cavity 13. The control device 7 includes a remote controller 72 located outside the bathroom and a main control component 71 electrically connected to the remote controller 72. The gas supply assembly 5 includes a gas proportional valve 52, and the blower assembly 6 includes a blower main body 61. The signal output end of the main control component 71 is respectively connected to the signal input end of the gas proportional valve 52 and the signal input end of the blower main body 61. When the user needs to switch the combustion mode of the burner assembly 4, the user touches the remote controller 72, and the remote controller 72 sends relevant instructions to the main control component 71. The main control component 71 controls the opening and closing size of the gas proportional valve 52 according to the received instructions to control the amount of gas entering the burner assembly 4, and the main control component 71 can also control the rotation speed of the blower main body 61 according to the received instructions to control the speed of external air entering the burner assembly 4, so as to achieve the effect of switching the combustion mode of the vehicle-mounted water heater, effectively solving the problem that the existing vehicle-mounted water heater cannot adjust the combustion mode according to the altitude environment requirements, resulting in energy waste or easy damage to the equipment.

[0069] The above only further illustrates the technical content of the present invention with embodiments to make it easier for readers to understand, but does not mean that the implementation manner of the present invention is limited to this.
