Description

Technical Field

[0001] This utility model relates to the field of gas appliance technology, and in particular to a gas appliance. Background Technology

[0002] Gas appliances are appliances that use manufactured gas, liquefied petroleum gas, natural gas, etc. as fuel, and include gas stoves, water heaters, wall-hung boilers, and other domestic and industrial equipment.

[0003] Gas appliances require a continuous intake of air to support combustion during operation; therefore, air inlets are typically installed on the casing to introduce combustion air. However, existing gas appliances use fixed-opening air inlets on the casing, with no adjustable airflow. This results in excessive airflow during low-load operation, affecting combustion stability or increasing noise. Under high-load conditions, insufficient airflow may lead to incomplete combustion and safety hazards. Furthermore, fixed air inlets are prone to rainwater backflow, dust accumulation, or insect infestation in inclement weather, affecting the cleanliness of the equipment's interior, heat dissipation efficiency, and even causing malfunctions. In addition, with a fixed air inlet design, the casing of the air inlet often needs to be designed differently for different gas appliance models to meet the airflow requirements of different products, increasing production and maintenance costs.

[0028] Figure 1 This is a partial structural diagram of a gas appliance provided in an embodiment of the present invention, showing only a portion of the gas appliance's casing. Figure 2 Is with Figure 1 A top view diagram of a corresponding gas appliance, such as... Figure 1 and Figure 2As shown, the gas appliance provided in this embodiment of the present invention includes multiple air inlet units 11, an air inlet adjustment structure 12, and a drive component 13. The air inlet units 11 are located on the housing 1 of the gas appliance and are arranged side by side at intervals along the first direction Y. Each air inlet unit 11 includes multiple air inlets 110 arranged side by side along the second direction X. The first direction Y and the second direction X intersect and are both parallel to the housing surface 10 where the air inlets 110 are located. The air inlet adjustment structure 12 is arranged in a one-to-one correspondence with the air inlet units 11. The drive component 13 is connected to the air inlet adjustment structure 12. The drive component 13 drives the air inlet adjustment structure 12 to move relative to the air inlet units 11 to adjust the air intake volume. Figure 1 In the middle, the third direction Z is perpendicular to the housing surface 10 where the air inlet 110 is located.

[0029] like Figure 1 As shown, the housing 1 of the gas appliance has multiple surfaces, and the housing surface 10 where the air inlet 110 is located can be at least one of these surfaces. For example, Figure 1 The illustration is based on an example where an air inlet 110 is provided on the bottom surface of the housing 1. In other embodiments, the air inlet 110 may also be provided on the side of the housing 1 as needed. It is understood that the air inlet 110 penetrates the housing surface 10 on which it is located.

[0030] like Figure 2 As shown, in order to achieve adjustable air intake and prevent damage to internal components caused by factors such as mosquitoes, in this embodiment, multiple air inlets 110 are arranged in a certain pattern along the first direction Y and the second direction X, and the multiple air inlets 110 arranged side by side along the second direction X are divided into an air intake unit 11, thereby obtaining multiple air intake units 11 arranged side by side at intervals along the first direction Y. Then, an air intake adjustment structure 12 is provided for each air intake unit 11, and the air intake adjustment structure 12 is connected to the driving component 13. The driving component 13 drives the air intake adjustment structure 12 to move relative to the air intake unit 11 to adjust the air intake volume.

[0031] Multiple air intake units 11 are arranged side by side at intervals along the first direction Y, which facilitates the use of the interval area to set up the air intake adjustment structure 12 and provides space for the movement of the air intake adjustment structure 12.

[0032] Specifically, the driving component 13 drives the air intake adjustment structure 12 to move relative to the air intake unit 11. This can be understood as the driving component 13 driving the air intake adjustment structure 12 to move away from or towards the air intake unit 11. When the air intake adjustment structure 12 moves away from the air intake unit 11, the opening / air intake area of ​​the air inlet 110 in the air intake unit 11 increases, resulting in increased airflow. Conversely, when the air intake adjustment structure 12 moves towards the air intake unit 11, the opening / air intake area of ​​the air inlet in the air intake unit 11 decreases, resulting in decreased airflow.

[0033] Optionally, the drive component 13 includes a drive motor.

[0034] Optionally, the initial position of the air intake adjustment structure 12 covers the air intake unit 11.

[0035] The initial position of the air intake adjustment structure 12 can be understood as the position of the air intake adjustment structure 12 when the gas appliance is in standby mode and there is no heating requirement. In standby mode, there is no need to introduce combustion air. At this time, the air intake adjustment structure 12 can cover the air intake unit 11, and the air intake adjustment structure 12 can be used to block mosquitoes, rainwater, dust and other substances from entering the equipment and avoid damaging the equipment.

[0036] When the user is detected activating the gas appliance for heating, the controllable drive component 13 is activated, driving the air intake adjustment structure 12 to move away from the air intake unit 11, thereby increasing the opening / air intake area of ​​at least a portion of the air intake 110, increasing the air intake volume, and providing the air required for combustion. When the gas appliance heating ends, the controllable drive component 13 drives the air intake adjustment structure 12 to move closer to the air intake unit 11, returning it to its initial position.

[0037] For different products, the above solution allows the housing of the air inlet to adopt the same design. Only the air intake volume needs to be adjusted according to the actual air intake volume requirements, thereby improving the versatility of the housing of the air inlet and saving costs.

[0038] In summary, this utility model embodiment sets up multiple air intake units arranged side by side and spaced apart along a first direction. Each air intake unit is provided with an air intake adjustment structure, and the air intake adjustment structure is connected to a driving component. The driving component drives the air intake adjustment structure to move relative to the air intake unit, which can realize the adjustment of the air intake volume and improve the versatility of the housing where the air intake is located. When the gas appliance is not started, the air intake adjustment structure can also be used to block the air intake to prevent mosquitoes, rainwater, dust and other substances from entering the equipment and damaging the equipment.

[0039] Based on the above embodiments, such as Figure 2 As shown, optionally, the gas appliance also includes a transmission mechanism 14, which is connected between the air intake adjustment structure 12 and the drive component 13. Thus, the drive component can drive the air intake adjustment structure 12 to move relative to the air intake unit 11 via the transmission mechanism 14.

[0040] like Figure 2 As shown, optionally, the driving component 13 drives the air intake adjustment structure 12 to move along the first direction Y within a preset movement range S. At this time, the air intake adjustment unit 12 can translate along the first direction Y, and the movement range is the preset movement range S.

[0041] Specifically, the preset movement range S corresponding to different air intake adjustment structures 12 is different. For any air intake unit 11, the preset movement range of the air intake adjustment structure 12 can be from the location of the air intake unit 11 (initial position) to the area above or below the air intake unit where no air intake unit is set (such as the interval area). When the air intake adjustment structure 12 moves within its preset movement range S, it can change to any state between blocking the air intake 110 and opening the air intake 110.

[0042] Further optionally, the width of the air intake adjustment structure 12 along the first direction Y is a first width, and the maximum value in the preset motion range S is less than or equal to twice the first width.

[0043] Understandably, when the movement distance of the air intake adjustment structure 12 is equal to the first width, all the air inlets 110 in the entire air intake unit 11 are exposed, and the air intake unit 11 is in the state of maximum air intake. When the movement distance is between zero and the first width, the air intake of the air intake unit 11 is less than its maximum air intake.

[0044] Optionally, along the first direction Y, the spacing between two adjacent air inlet units 11 is greater than or equal to the first width, so as to ensure that the air inlet adjustment structure 12 can fully open the air inlet 110.

[0045] When the air intake adjustment structure 12 moves in translation along the first direction Y, the transmission mechanism 14 may optionally include, but is not limited to, the guide rail.

[0046] Figure 3 Is with Figure 1 A top view diagram of another corresponding gas appliance, such as... Figure 3 As shown, optionally, the driving component 13 drives the air intake adjustment structure 12 to rotate around the first axis 121 within a preset angle range; the first axis 121 is parallel to the second direction X, and the rotation angle of the air intake adjustment structure 12 is the angle between the plane where the air intake adjustment structure 12 is located and the shell surface 10.

[0047] Specifically, each air intake adjustment structure 12 corresponds to a different first axis 121. For example... Figure 3As shown, the air intake adjustment structure 12 includes a first edge (upper edge) and a second edge (lower edge) opposite each other along the first direction Y. For any air intake adjustment structure 12, the first axis 121 can be one of the edges (upper edge or lower edge) of the air intake adjustment structure 12 in the first direction Y. For example, taking the upper edge of the air intake adjustment structure 12 in the first direction Y as the first axis 121, in the initial position, the air intake adjustment structure 12 is parallel to the housing surface 10 where the air inlet 110 is located. When the gas appliance starts heating, the driving component 13 drives the air intake adjustment structure 12 to rotate in a direction away from the air inlet 110. The lower edge of the air intake adjustment structure 12 will gradually move away from the air inlet 110, thereby increasing the opening / air intake area of ​​the air inlet and increasing the air intake volume.

[0048] Optionally, the preset angle range is 0 degrees to 90 degrees.

[0049] When the rotation angle of the air intake adjustment structure 12 is 0 degrees, the air intake adjustment structure 12 is in the initial position. When the rotation angle of the air intake adjustment structure 12 is 90 degrees, the air inlet 110 of the corresponding air intake unit 11 is fully exposed, and the air intake unit 11 is in the state of maximum air intake. When the rotation angle is between 0 degrees and 90 degrees, the air intake of the air intake unit 11 is less than its maximum air intake.

[0050] When the air intake adjustment structure 12 rotates around the first axis 121, the transmission mechanism 14 may optionally include, but is not limited to, gears.

[0051] like Figure 2 or Figure 3 As shown, optionally, the drive component 13 is configured in a one-to-one correspondence with the air intake adjustment structure 12. In other words, one drive component 13 is used to drive the movement of one air intake adjustment structure 12. With this configuration, the air intake volume of each air intake unit 11 can be adjusted individually.

[0052] For example, when the actual air intake demand is less than the maximum air intake that all air inlets 110 can provide, a portion of the drive components 13 can be activated to drive the corresponding air intake adjustment structure 12 to move (translate or rotate) away from the air intake unit 11, so as to achieve on-demand air intake, improve combustion stability, and reduce noise.

[0053] Figure 4 Is with Figure 1 A top view diagram of another corresponding gas appliance, such as... Figure 4 As shown, optionally, one drive component 13 is connected to multiple air intake adjustment structures 12. This configuration allows one drive component 13 to simultaneously drive the movement (translation or rotation) of multiple air intake adjustment structures 12, reducing manufacturing costs.

[0054] In one specific embodiment, one drive component 13 may be connected to all air intake adjustment structures 12. Specifically, the drive component 13 is connected to all air intake adjustment structures 12 through the same transmission mechanism 14. In this case, the amount of movement of the air intake adjustment structure 12 can be controlled by controlling the rotation step size of the drive motor 13, thereby controlling the opening degree / opening area of ​​each air inlet 110 to achieve on-demand air intake.

[0055] Optionally, the air intake adjustment structure 12 and the drive component 13 are both located inside the housing 1. This arrangement helps to ensure the reliability and service life of the equipment.

[0056] like Figure 2 As shown, optionally, the gas appliance also includes a limit switch 15, which is located on at least one side of the air intake unit 11 along the second direction X.

[0057] Specifically, along the second direction X, a limit switch can be set on one side of the air inlet unit 11, or limit switches 15 can be set on both opposite sides of the air inlet unit.

[0058] When the drive mechanism 13 is set in a one-to-one correspondence with the air intake adjustment structure 12, each air intake unit 11 is equipped with a limit switch 15; when one drive mechanism 13 is set in a correspondence with multiple air intake adjustment structures 12, at least some air intake units 11 can be equipped with limit switches 15.

[0059] The limit switch 15 serves as a sensor to detect the position of the air intake adjustment structure 12. In this embodiment, the limit switch 15 is positioned beside the air intake unit 11. When the air intake adjustment structure 12 is in its initial position, it contacts the limit switch 15. At this time, the equipment is in a closed state, which can effectively prevent dust, insects, and rainwater from entering the housing and causing pollution or damage to the equipment.

[0060] When the air intake adjustment structure 12 moves a certain distance from its initial position, the switch state of the limit switch 15 changes, confirming that the air intake adjustment structure 12 is moving normally (translating or rotating). When the gas appliance heating is detected to be finished, the drive component 13 can be controlled to reverse, driving the air intake adjustment structure 12 back to its initial position and contacting the limit switch, confirming that the air intake adjustment structure 12 has returned to its normal position, thus avoiding internal contamination and equipment damage.

[0061] Reference Figures 2-4The technical solution of this utility model embodiment arranges the air inlet 110 in two dimensions and adds multiple air inlet adjustment structures 12 arranged side by side to form an air inlet adjustment module similar to a louver. Each air inlet adjustment structure 12 is similar to the blades of a louver. Under the drive of the driving component, the multiple air inlet adjustment structures 12 can move independently or synchronously to adjust the air volume and improve the versatility of the housing where the air inlet is located. When the gas appliance is not heated, the air inlet adjustment structure 12 can also be used to prevent dust, mosquitoes and rainwater from entering the housing and causing pollution and damage to the equipment.

[0062] Optionally, gas appliances include, but are not limited to, gas water heaters and gas wall-hung boilers.

[0063] The specific embodiments described above do not constitute a limitation on the scope of protection of this utility model. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
