[0028] The implementation modes of the present utility model are described in detail below in conjunction with the accompanying drawings.
[0029] like Figures 1 to 7 A vehicle-mounted water heater with an anti-backwind smoke guiding device shown in the figure comprises a shell 1, the shell 1 comprises a smoke exhaust port 2 located on the front of the shell 1, a smoke inlet 3 located on the back of the shell 1 and connected to the fan assembly, a smoke guiding cavity 11 is provided on the shell 1, the smoke inlet 3 is communicated with the smoke exhaust port 2 through the smoke guiding cavity 11, a smoke guiding mechanism 4 connected to the smoke inlet 3 to guide smoke to be discharged to the outside through the smoke exhaust port 2, and a wind shielding mechanism 5 located below the smoke guiding mechanism 4, the wind shielding mechanism 5 is used to block the external wind blown into the smoke guiding cavity 11 through the smoke exhaust port 2, so that the external wind flows back to the smoke exhaust port 2 through the wind shielding mechanism 5 for discharge;
[0030] The utility model discloses a vehicle-mounted water heater with an anti-backwind smoke guiding device, by arranging a wind shield mechanism on the smoke guiding cavity, when external wind enters the smoke guiding cavity through the smoke exhaust port, the wind shield mechanism effectively blocks the path of the external wind entering the smoke inlet port, so that the external wind cannot drive the smoke to flow back into the smoke inlet port, effectively solving the problem that the smoke generated by the existing vehicle-mounted water heater when using gas for heating is discharged to the external environment through the smoke exhaust channel, but in windy weather, the wind can easily enter the smoke exhaust channel from the outside, so that the smoke can flow back into the vehicle-mounted water heater under the action of the external wind force, affecting the normal operation of the vehicle-mounted water heater, and in severe cases even causing the vehicle-mounted water heater to be extinguished, thereby failing to operate normally.
[0031] like Figures 1 to 7 The wind shield mechanism 5 shown includes an auxiliary smoke guide plate 51 located below the smoke guide mechanism 4 and connected to the smoke inlet 3 at one end, and a wind shield plate 52 obliquely connected to one end of the auxiliary smoke guide plate 51 close to the smoke inlet 3. The auxiliary smoke guide plate 51 and the wind shield plate 52 enclose a wind shield space 53 communicating with the smoke exhaust port 2.
[0032] Furthermore, the auxiliary smoke guide plate 51 is located at the bottom of the smoke inlet 3, and the wind shield 52 is arranged to extend downwardly and obliquely toward the direction of the smoke exhaust port 2. The auxiliary smoke guide plate 51 and the wind shield 52 are located at the bottom of the smoke inlet 3 and are obliquely connected to form a "C" shape. The height of the wind shield space 53 is greater than the height of the smoke exhaust port 2. The oblique connection between the auxiliary smoke guide plate 51 and the wind shield 52 can block the external wind from moving toward the smoke inlet 3, so that the external wind can flow back to the smoke exhaust port 2 through the wind shield space 53.
[0033] Furthermore, the wind shielding space 53 opens toward the smoke exhaust port 2, which helps guide the smoke and external wind to move toward the smoke exhaust port 2, thereby enhancing the guiding effect of the smoke and external wind and effectively improving the smoke exhaust efficiency.
[0034] Optionally, in some embodiments, the auxiliary smoke guide plate 51 and the wind shield plate 52 may be connected by snap connection, lock connection, magnetic connection, threaded connection or the like.
[0035] Furthermore, as a preferred embodiment of the present invention but not a limitation, the auxiliary smoke guide plate 51 and the wind shield plate 52 are integrally formed. The integrally formed setting is conducive to simplifying the structure of the smoke exhaust device, reducing the connection and installation processes between components, effectively reducing the manufacturing cost, and improving the stability of the system; secondly, the integrally formed setting can increase the overall stability of the smoke exhaust device, and the connection between the auxiliary smoke guide plate 51 and the wind shield plate 52 is not prone to loosening or falling off, and can better withstand the vibration and impact of the external environment.
[0036] Furthermore, the auxiliary smoke guide plate 51 and the wind shield plate 52 are integrally formed so that their shapes and angles of connection can better match each other to form a more effective wind shielding structure, thereby effectively enhancing the anti-backwind effect.
[0037] like Figures 1 to 7 The auxiliary smoke guide plate 51 is arranged along the width direction of the housing 1.
[0038] The auxiliary smoke guide plate 51 is arranged to extend obliquely toward the smoke exhaust port 2 at one end away from the smoke inlet 3, and an auxiliary smoke exhaust channel 40 for guiding smoke to the smoke exhaust port 2 is formed between the auxiliary smoke guide plate 51 and the smoke guide mechanism 4;
[0039] Furthermore, the auxiliary smoke guide plate 51 is arranged along the width direction of the shell 1, and the length of the auxiliary smoke guide plate 51 along the width direction of the shell 1 is the same as the width of the shell 1, which can effectively guide the smoke to move along a fixed path to the smoke exhaust port 2, enhance the smoke guiding effect, and help improve the smoke exhaust efficiency.
[0040] Furthermore, an auxiliary smoke exhaust channel 40 is formed between the auxiliary smoke guide plate 51 and the smoke guide mechanism 4. The auxiliary smoke exhaust channel 40 is located at the lower part of the smoke inlet 3. The setting of the auxiliary smoke exhaust channel 40 is conducive to diverting the smoke so that the flow of the smoke is more uniform, reducing the resistance of the smoke during the smoke exhaust process, and effectively improving the smoothness of the smoke exhaust.
[0041] Furthermore, the auxiliary smoke guide plate 51 is tilted downwardly toward the smoke exhaust port 2 away from the end of the smoke inlet 3, which is beneficial to avoid backflow of smoke during the smoke exhaust process, ensuring that the smoke can be smoothly discharged from the smoke inlet 3 through the auxiliary smoke exhaust channel 40 to the smoke exhaust port 2, effectively avoiding the occurrence of smoke backflow.
[0042] like Figures 1 to 7The smoke guide mechanism 4 shown includes a first smoke guide plate 41 arranged along the width direction of the housing 1, and a first smoke exhaust channel 411 communicating with the smoke exhaust port 2 is formed between the first smoke guide plate 41 and the top inner side wall of the housing 1;
[0043] Furthermore, the first smoke guide plate 41 is arranged along the width direction of the shell 1, and the length of the first smoke guide plate 41 along the width direction of the shell 1 is the same as the width of the shell 1, which can effectively guide the smoke to move along a fixed path to the smoke exhaust port 2, enhance the smoke guiding effect, and help improve the smoke exhaust efficiency.
[0044] Furthermore, a first smoke exhaust channel 411 is formed between the first smoke guide plate 41 and the inner wall of the top of the shell 1. The first smoke exhaust channel 411 is located at the upper part of the smoke inlet 3. The setting of the first smoke exhaust channel 411 is conducive to diverting the smoke so that the flow of the smoke is more uniform, reducing the resistance of the smoke during the smoke exhaust process, and effectively improving the smoothness of the smoke exhaust.
[0045] like Figures 1 to 7 The first smoke guide plate 41 shown is arranged to extend obliquely toward the smoke exhaust port 2 at one end away from the smoke inlet 3;
[0046] Furthermore, the first smoke guide plate 41 is tilted downwardly toward the smoke exhaust port 2 away from the end of the smoke inlet 3, which is beneficial to avoid backflow of smoke during the smoke exhaust process, ensuring that the smoke can be smoothly discharged from the smoke inlet 3 through the first smoke exhaust channel 411 to the smoke exhaust port 2, effectively avoiding the occurrence of smoke backflow.
[0047] like Figures 1 to 7 The first smoke guide plate 41 shown is located between the smoke inlets 3, and the smoke inlet 3 is divided into a first smoke inlet 31 and a second smoke inlet 32 located below the first smoke inlet 31 by the first smoke guide plate 41, the first smoke inlet 31 corresponds to the first smoke exhaust channel 411, an auxiliary smoke exhaust channel 40 is formed between the first smoke guide plate 41 and the wind shielding mechanism 5, and the second smoke inlet 32 corresponds to the auxiliary smoke exhaust channel 40.
[0048] Specifically, the first smoke guide plate is laterally arranged between the smoke inlets along the width direction of the shell, and the first smoke guide plate divides the smoke inlet into a first smoke inlet and a second smoke inlet located below the first smoke inlet. The first smoke inlet is communicated with the first smoke exhaust channel, and the second smoke inlet is communicated with the auxiliary smoke exhaust channel. Part of the smoke enters the first smoke exhaust channel from the first smoke inlet and is discharged to the outside through the first smoke exhaust channel, and the other part of the smoke enters the auxiliary smoke exhaust channel through the second smoke inlet and is discharged to the outside through the auxiliary smoke exhaust channel.
[0049] like Figures 1 to 7The maximum vertical height of the smoke outlet 2 from the bottom of the shell 1 is H1, and the shortest vertical distance of the smoke guide mechanism 4 from the bottom of the shell 1 is H2, H1<H2;
[0050] Furthermore, the distance from the smoke exhaust port 2 to the bottom of the shell 1 is smaller than the distance from the smoke guide mechanism 4 to the bottom of the shell 1, that is, the height of the smoke exhaust port 2 is lower than the height of the smoke guide mechanism 4, which effectively prevents the smoke and external wind from flowing back into the smoke inlet 3, which is beneficial to ensuring the normal operation and safe use of the device.
[0051] Furthermore, the height of the smoke exhaust port 2 is lower than that of the smoke guide mechanism 4, so that smoke is not easily retained on the smoke guide mechanism 4 during the smoke exhaust process, and can be discharged to the smoke exhaust port 2 more quickly, reducing the impact of smoke on the inside of the device.
[0052] like Figures 1 to 7 The maximum vertical height of the smoke outlet 2 from the bottom of the housing 1 is H1, and the shortest vertical distance of the auxiliary smoke guide plate 51 from the bottom of the housing 1 is H3, H1<H3;
[0053] Furthermore, the distance from the smoke exhaust port 2 to the bottom of the shell 1 is smaller than the distance from the auxiliary smoke guide plate 51 to the bottom of the shell 1, that is, the height of the smoke exhaust port 2 is lower than the height of the auxiliary smoke guide plate 51, which effectively prevents the smoke and external wind from flowing back into the smoke inlet 3, which is beneficial to ensuring the normal operation and safe use of the device.
[0054] Furthermore, the height of the smoke exhaust port 2 is lower than that of the auxiliary smoke guide plate 51, so that smoke is not easily retained on the auxiliary smoke guide plate 51 during the smoke exhaust process, and can be discharged to the smoke exhaust port 2 more quickly, reducing the impact of smoke on the inside of the device.
[0055] like Figures 1 to 7 The smoke exhaust port 2 shown includes a first smoke exhaust port 21 and a second smoke exhaust port 22 located below the first smoke exhaust port 21 and spaced apart from the first smoke exhaust port 21. The first smoke exhaust port 21 and the second smoke exhaust port 22 are both extended along the width direction of the housing 1.
[0056] Furthermore, by providing the first smoke exhaust port 21 and the second smoke exhaust port 22, smoke can be diverted, thereby enhancing the efficiency of smoke exhaust. The two smoke exhaust ports working together can exhaust smoke more quickly, which is beneficial to improving the processing capacity of smoke exhaust.
[0057] Furthermore, the cross-sections of the first smoke exhaust port 21 and the second smoke exhaust port 22 are both rectangular and extend along the width direction of the shell 1, which helps to achieve an efficient anti-backwind effect. This arrangement can make the smoke more evenly distributed around the first smoke exhaust port 21 and the second smoke exhaust port 22, thereby forming a certain airflow barrier to block the direct impact of external wind on the first smoke exhaust port 21 and the second smoke exhaust port 22, thereby reducing the interference of external wind on the normal smoke exhaust of the smoke exhaust system; secondly, the shape of the rectangular cross-section is also conducive to more effectively controlling the flow direction of the smoke, so that it can be discharged to the outside more stably, effectively improving the reliability and efficiency of smoke exhaust.
[0058] Furthermore, the provision of the first smoke exhaust port 21 and the second smoke exhaust port 22 is conducive to increasing the stability of the smoke exhaust system. When one of the smoke exhaust ports has a problem or requires maintenance, the other smoke exhaust port can still work normally, which is conducive to ensuring the continuity and stability of smoke exhaust.
[0059] like Figures 1 to 7 The smoke guide mechanism 4 and the wind shield mechanism 5 shown are both provided with a connection portion 6 connected to the housing 1, and the housing 1 is provided with a positioning installation hole 12, and the positioning installation hole 12 is threadedly connected to the connection portion 6, so that the smoke guide mechanism 4 and the wind shield mechanism 5 are both detachably connected to the housing 1;
[0060] Optionally, in some embodiments, the connection between the smoke guide mechanism 4 and the shell 1 can be achieved by snap connection, lock connection, magnetic connection or the like.
[0061] Optionally, in some other embodiments, the connection between the wind shield mechanism 5 and the shell 1 can be achieved by snap connection, lock connection, magnetic connection or the like.
[0062] Furthermore, as a preferred embodiment of the present invention but not a limitation, the smoke guide mechanism 4 and the wind shield mechanism 5 are both connected to the housing 1 by threaded connection.
[0063] Furthermore, the matching connection between the positioning mounting hole 12 and the connecting part 6 can ensure that the smoke guide mechanism 4 and the wind shield mechanism 5 can be accurately positioned during installation, avoiding installation deviation or instability, effectively ensuring the normal operation of the smoke exhaust device, and facilitating its adjustment and positioning.
[0064] Specifically, the connection parts 6 are located at both ends of the first smoke guide plate 41 , one end of the auxiliary smoke guide plate 51 close to the smoke exhaust port 2 , and one end of the wind shield plate 52 close to the smoke exhaust port 2 .
[0065] The implementation method of this embodiment is as follows:
[0066] A vehicle-mounted water heater with an anti-backwind smoke guiding device comprises a shell 1, the shell 1 comprises a smoke exhaust port 2 located on the front of the shell 1 and a smoke inlet 3 located on the back of the shell 1, a smoke guiding cavity 11 is arranged inside the shell 1, the smoke inlet 3 is communicated with the smoke exhaust port 2 through the smoke guiding cavity 11, a smoke guiding mechanism 4 and a wind shielding mechanism 5 are arranged on the smoke guiding cavity 11, the smoke guiding mechanism 4 comprises a first smoke guiding plate 41, the wind shielding mechanism 5 comprises an auxiliary smoke guiding plate 51 located below the first smoke guiding plate 41, and an auxiliary smoke guiding plate 51 located below the auxiliary smoke guiding plate 51 and connected to the auxiliary smoke guiding plate 51. The smoke plate 51 is connected to the windshield 52 at an angle near one end of the smoke inlet 3, a first smoke exhaust channel 411 is formed between the first smoke guide plate 41 and the inner side wall of the top of the shell 1, an auxiliary smoke exhaust channel 40 is formed between the first smoke guide plate 41 and the auxiliary smoke guide plate 51, and a windshield space 53 is formed between the auxiliary smoke guide plate 51 and the windshield 52. The first smoke exhaust channel 411 is located at the upper part of the smoke inlet 3, the auxiliary smoke exhaust channel 40 is located at the lower part of the smoke inlet 3, and the windshield space 53 is located below the auxiliary smoke exhaust channel 40. When the vehicle is heated When the water heater uses gas to heat water, smoke is generated. The smoke enters the smoke guide cavity 11 through the smoke inlet 3. A part of the smoke is guided to the smoke exhaust port 2 through the first smoke guide channel 411 and discharged to the outside. The other part of the smoke is guided to the smoke exhaust port 2 through the auxiliary smoke exhaust channel 40 and discharged to the outside, thereby stably discharging the smoke. When encountering windy weather, the external wind enters the smoke guide cavity 11 through the smoke exhaust port 2 to the windshield space 53. The windshield space 53 opens toward the smoke exhaust port 2, and the windshield space 53 blocks the path of the external wind to the smoke inlet 3 Under the action of the windshield space 53, the external wind flows back to the smoke exhaust port 2 and is discharged to the outside, so that the external wind cannot drive the smoke to flow back into the smoke inlet 3, which effectively solves the problem that the smoke generated by the existing vehicle water heater using gas for heating is discharged to the external environment through the smoke exhaust channel, but when encountering windy weather, the wind can easily enter the smoke exhaust channel from the outside, so that the smoke can flow back into the vehicle water heater under the action of the external wind force, affecting the normal operation of the vehicle water heater, and even causing the vehicle water heater to be extinguished, so that it cannot operate normally.
