Description

Technical Field

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

[0002] Currently, the blowers in existing gas water heaters are often only used to supply the air required for combustion. Furthermore, gas water heaters are typically placed in kitchen environments, which may require cooling for users due to heat dissipation from combustion and cooking. Since kitchen space is often limited, adding additional cooling units would take up even more installation space.

[0003] Therefore, how to utilize the blower in existing gas water heaters to achieve the function of cooling and heat dissipation for users has become a technical problem that urgently needs to be solved in this field. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the blower function of the existing gas water heater, which is limited and cannot deliver air to the user, and to provide a gas water heater.

[0005] This utility model solves the above-mentioned technical problems through the following technical solution: A gas water heater includes a blower, and the gas water heater also includes an air supply device. The air supply device is located at the top of the gas water heater and includes an air outlet, a flue gas outlet, and a wind deflector. The air outlet and the flue gas outlet are both located on the outer surface of the air supply device. The air outlet is located at least on the front of the gas water heater, and the flue gas outlet is located on the back of the gas water heater. The air supply device is connected to the blower, and the wind deflector is located inside the air supply device. The wind deflector can switch the connection relationship between the outlet of the blower and the air outlet and the flue gas outlet.

[0006] This gas water heater, by adding an air supply device including an air inlet, a flue outlet, and a baffle, can fully utilize the power of the existing blower to achieve cold air cooling for users without adding additional drive equipment. The air inlet, located on the front of the water heater, directs airflow towards the user, while the flue outlet, located on the back, can directly connect to a pre-installed flue or exhaust vent in the wall, adapting to common wall-mounted installation scenarios. The baffle can adjust the connection between the blower outlet and the air inlet and flue outlet to accommodate different cooling needs in various scenarios. Without altering the core heating structure of the gas water heater, this solution expands the cooling function with air supply, enabling a single device to perform both flue exhaust and cooling functions.

[0007] Preferably, there are multiple air outlets, and the air outlets are located on the side of the gas water heater.

[0008] Setting multiple air outlets on the front and sides of a gas water heater can significantly increase the total air volume, avoiding the problem of insufficient cooling capacity caused by the limited area or partial obstruction of a single air outlet. At the same time, it can be combined with the function of wind deflectors to improve the flexibility of the entire air supply device in terms of user orientation.

[0009] Preferably, the gas water heater further includes a combustion chamber.

[0010] The outlet of the blower is directly connected to the air inlet of the combustion chamber, and the flue gas outlet of the combustion chamber is directly connected to the air supply device.

[0011] Alternatively, the flue gas outlet of the combustion chamber is directly connected to the inlet of the blower, and the outlet of the blower is directly connected to the air supply device.

[0012] When the blower of the gas water heater is located below the combustion chamber, the blower outlet is directly connected to the air inlet of the combustion chamber, and the air supply device can be directly connected to the flue gas outlet of the combustion chamber. When the blower of the gas water heater is located above the combustion chamber, the flue gas outlet of the combustion chamber is directly connected to the blower inlet, and the air supply device can be directly connected to the blower outlet.

[0013] Preferably, the air supply device includes a connector and multiple air ducts, some of the air ducts are configured to correspond one-to-one with multiple air supply outlets, and the remaining air ducts are configured one-to-one with multiple smoke exhaust outlets. The connector is connected to the corresponding air supply outlet and / or smoke exhaust outlet through the multiple air ducts.

[0014] Each air outlet or exhaust vent is supplied with air by an independent duct, which can precisely control the air volume in different directions on the front or side of the gas water heater. This design can avoid crossflow interference between air outlets and allow air outlets in different locations to work as needed.

[0015] Preferably, the outer surface of the connector is cylindrical, the wind deflector covers the outer surface of the connector and rotates about the axis of the connector, and each of the air ducts is distributed on the outside of the wind deflector;

[0016] When the wind deflector rotates, it changes the connection between each air duct and the connecting member by blocking the airflow.

[0017] When the wind deflector rotates around the axis of the connector, its relative position with each air duct changes continuously. By finely adjusting the rotation angle, linear control of the air duct obstruction area can be achieved, thereby making the air volume distribution of each air outlet or smoke outlet more precise and adaptable to the user's refined needs for different cooling areas and different air volumes.

[0018] Preferably, the two ends of the connector are an open end and a closed end, respectively. The open end is connected to the outlet of the blower, and the inner surface of the connector has multiple notches that are connected to the air ducts one by one, so as to form an inlet for the air ducts to connect with the connector.

[0019] The closed end of the connector prevents airflow from the blower from leaking out, creating a concentrated pressure chamber inside the connector. This ensures more airflow enters the corresponding duct through the notch on the inner surface, reducing unnecessary loss. The notch, acting as the duct inlet, is directly located on the inner surface of the connector, with a clearer relative position to the baffle. When the baffle rotates, it can precisely align with or block specific notches, reducing adjustment errors caused by ambiguous inlet positions and ensuring that the open or closed state of each duct matches the user's visual expectations.

[0020] Preferably, the air supply device includes a box-shaped outer shell, a cavity is formed inside the box-shaped outer shell, and a plurality of air ducts are independently separated within the cavity;

[0021] And / or, the air ducts are evenly distributed within the cavity.

[0022] The box-shaped outer shell serves as a container for the air ducts, allowing multiple air ducts to be housed within the cavity, avoiding the space waste caused by scattered air duct arrangements. Simultaneously, the box-shaped outer shell provides physical protection for the internal air ducts, preventing them from being deformed by impacts or pressure during water heater operation. Furthermore, the independent separation of multiple air ducts within the box-shaped cavity prevents crosstalk between different air ducts during flow.

[0023] Evenly distributed air ducts create a relatively stable pressure environment within the cavity. This ensures that each duct inlet is under similar pressure conditions, preventing differences in airflow at the outlets caused by varying density in different duct sections. Furthermore, evenly distributed air ducts allow for smoother airflow distribution within the cavity, reducing airflow collisions or swirling at different duct inlets and thus lowering wind noise.

[0024] Preferably, the air supply device further includes multiple partition structures, which are disposed within the cavity to form the air duct.

[0025] By using a partition structure to create an air duct within the cavity, the design and manufacturing costs of this structure are relatively low.

[0026] Preferably, the plurality of partition structures are integrally formed with the box-shaped outer shell.

[0027] Compared to a split design, the connection between the partition structure and the box-shaped outer shell is less likely to develop gaps during use, thus preventing airflow from flowing out of the gaps and causing airflow loss into the air duct.

[0028] Preferably, the wind deflector includes a lever disposed on the outer surface of the wind deflector. The lever is used to drive the wind deflector to move in order to switch the connection relationship between the outlet of the blower and the air supply port and the smoke exhaust port.

[0029] By placing the lever on the outer surface of the wind deflector, it is easier and less strenuous for users to operate the wind deflector. At the same time, the lever has a short transmission path and a clear force point, which can meet the user's real-time response requirements to changes in airflow.

[0030] The significant advantages of this invention are as follows: By adding an air supply device including an air inlet, a flue outlet, and a baffle, this gas water heater can fully utilize the power of the existing blower to achieve cold air cooling for the user without adding additional drive equipment. The air inlet, located on the front of the gas water heater, directs airflow towards the user, while the flue outlet, located on the back, can directly connect to a pre-installed flue or exhaust vent in the wall, adapting to common wall-mounted installation scenarios. The baffle can adjust the connection between the blower outlet and the air inlet and flue outlet, thus adapting to the user's cooling needs in different scenarios. Without altering the core heating structure of the gas water heater, this solution expands the cooling function to include both flue ventilation and cooling, enabling a single device to perform both functions.

[0061] The present invention will be described more clearly and completely below with reference to the accompanying drawings, using a preferred embodiment.

[0062] like Figure 7 As shown, this utility model provides a gas water heater 1000, which includes a blower 7, a combustion chamber 8, a gas collection hood 9, and an air supply device 1. The blower 7 is located above the combustion chamber 8, and the flue gas outlet of the combustion chamber 8 is connected to the inlet of the blower 7 via the gas collection hood 9. The blower 7 draws the high-temperature flue gas generated by the combustion of the flame at the burner in the combustion chamber 8 upwards to the outlet of the blower 7. To enable the blower 7 of the gas water heater 1000 to perform more functions, the gas water heater 1000 is also equipped with an air supply device 1, which is located at the top of the gas water heater 1000 and directly connected to the outlet of the blower 7.

[0063] like Figures 1-7 As shown, the air supply device 1 includes a box-shaped outer shell 40, a connector 31, and a baffle 20. Fifteen air outlets 10 are provided on the outer surface of the box-shaped outer shell 40 (specifically, nine air outlets 10 are provided on the front 42 and three on each of the two sides 43). Nine smoke exhaust outlets 11 are also provided on the back 41 of the box-shaped outer shell 40. A cavity 50 is formed within the box-shaped outer shell 40, and twenty-four partition structures 60 are provided within the cavity 50 to form twenty-four evenly distributed air ducts 32. Each air duct 32 and the connector 31 together constitute a part of the air supply device 1. The outlet of the blower 7 is connected to each air outlet 10 and smoke exhaust outlet 11 via the air supply device 1. The baffle 20 is located inside the air supply device 1 and can switch the connection relationship between the outlet of the blower 7 and the air outlets 10 and smoke exhaust outlets 11.

[0064] When the combustion chamber 8 is not working but the blower 7 is working, the user can adjust the hollow structure 22 of the baffle 20 toward the air outlet 10, at which time the gas water heater 1000 can provide air supply and cooling function; when both the blower 7 and the combustion chamber 8 are working, the user can adjust the hollow structure 22 of the baffle 20 toward the flue gas outlet 11, at which time the gas water heater 1000 is in the working state of combustion and heating water temperature.

[0065] In this embodiment, the gas water heater 1000, by adding an air supply device 1 including an air outlet 10, a flue gas outlet 11, and a baffle 20, can fully utilize the power of the existing blower 7 to achieve the function of cooling the user with cold air without adding additional drive equipment. The air outlet 10, located on the front 42 of the gas water heater 1000, can deliver air to the user, while the flue gas outlet 11, located on the back 41 of the gas water heater 1000, can directly connect to the pre-set flue or exhaust hole in the wall, adapting to the common scenario of wall-mounted installation. The baffle 20 can adapt to the user's cooling needs in different scenarios by changing the connection relationship between the outlet of the blower 7 and the air outlet 10 and the flue gas outlet 11. Without changing the core heating structure of the gas water heater 1000, this solution expands the function of air supply and cooling, enabling a single device to have both exhaust and air supply cooling functions. In other embodiments, the number of air outlets 10 can also be two or more, which can be adjusted according to design requirements.

[0066] like Figures 1-7 As shown, there are multiple air outlets 10 (specifically fifteen), and the air outlets 10 are also located on the side 43 of the gas water heater 1000 (specifically three on each side).

[0067] In this embodiment, multiple air outlets 10 are provided on the front 42 and side 43 of the gas water heater 1000, which can significantly increase the total air supply and avoid the problem that the air outlet 10 is too unidirectional or that the air supply cooling capacity is insufficient due to area limitation or partial obstruction. At the same time, it can be combined with the function of the wind deflector 20 to improve the flexibility of the entire air supply device 1 in terms of user orientation.

[0068] like Figures 1-7 As shown, in this embodiment, since the blower 7 of the gas water heater 1000 is located above the combustion chamber 8, the flue gas outlet of the combustion chamber 8 passes through the gas collection hood 9 and connects to the inlet of the blower 7, and the outlet of the blower is directly connected to the air supply device 1.

[0069] like Figures 1-7 As shown, the air supply device 1 is connected to the outlet of the blower 7. The air supply device 1 includes a connector 31 and twenty-four air ducts 32, of which fifteen air ducts 32 are set one-to-one with the air supply outlet 10 and nine air ducts 32 are set one-to-one with the smoke exhaust outlet 11. The connector 31 is connected to the corresponding air supply outlet 10 and smoke exhaust outlet 11 through the air ducts 32.

[0070] In this embodiment, each air outlet 10 is supplied with air by an independent air duct 32, which can precisely control the air volume in different directions of the front 42 or side 43 of the gas water heater 1000. This design can avoid crossflow interference between air outlets 10 and allow air outlets 10 in different positions to work as needed.

[0071] like Figures 1-7 As shown, the outer surface of the connector 31 is cylindrical, the wind deflector 20 covers the outer surface of the connector 31 and rotates around the axis of the connector 31, and each air duct 32 is distributed on the outside of the wind deflector 20.

[0072] When the wind deflector 20 rotates, it changes the connection between each air duct 32 and the connector 31 by blocking the airflow.

[0073] In this embodiment, when the wind deflector 20 rotates around the axis of the connector 31, its relative position with each air duct 32 changes continuously. By finely adjusting the rotation angle, linear control of the shading area of ​​the air duct 32 can be achieved, thereby making the air volume distribution of each air outlet 10 or smoke outlet 11 more precise and able to meet the user's refined needs for different cooling areas and different air volumes.

[0074] like Figures 1-7As shown, the two ends of the connector 31 are an open end 311 and a closed end 312, respectively. The open end 311 is connected to the outlet of the blower. The connector 31 extends into the cavity 50 and protrudes from the outside of the box-shaped outer shell 40. Twenty-four notches 313 are opened on the inner surface of the connector 31, which are connected to the air duct 32 one by one, to form an inlet for the air duct 32 to connect with the connector 31.

[0075] In this embodiment, the closed end 312 of the connector 31 prevents the airflow from the blower 7 from leaking from the end, forming a concentrated pressure chamber inside the connector 31. This ensures that more airflow enters the corresponding air duct 32 through the notch 313 on the inner surface, reducing ineffective loss. The notch 313, as the inlet of the air duct 32, is directly opened on the inner surface of the connector 31, and its relative position to the baffle 20 is more clearly defined. When the baffle 20 rotates, it can accurately align with or block a specific notch 313, reducing adjustment errors caused by ambiguous inlet positions and ensuring that the opening or closing state of each air duct 32 is consistent with the user's visual expectations.

[0076] like Figures 1-7 As shown, the air supply device 1 includes a box-shaped outer shell 40, and a cavity 50 is formed inside the box-shaped outer shell 40. Twenty-four air ducts 32 are independently separated in the cavity 50.

[0077] In this embodiment, the box-shaped outer shell 40 serves as a container for the air ducts 32, enabling the multiple air ducts 32 to be centrally housed within the cavity 50. This avoids the space wastage caused by the dispersed arrangement of the air ducts 32. Simultaneously, the box-shaped outer shell 40 provides physical protection for the internal air ducts 32, preventing them from being impacted or deformed during operation of the gas water heater 1000. Furthermore, the independent separation of the multiple air ducts 32 within the cavity 50 prevents crosstalk between the airflow from different air ducts 32 during flow.

[0078] like Figures 1-7 As shown, twenty-four air ducts 32 are evenly distributed within the cavity 50.

[0079] In this embodiment, the uniformly distributed air ducts 32 can create a relatively stable pressure environment for the airflow within the cavity 50. The uniform distribution of the air ducts 32 ensures that the inlet of each air duct 32 is under similar pressure conditions, avoiding differences in airflow at the air outlet 10 caused by the density or sparseness of local areas within the air ducts 32. Simultaneously, the uniformly distributed air ducts 32 allow for smoother airflow distribution within the cavity 50, reducing airflow collisions or swirling at the inlets of different air ducts 32, thereby reducing wind noise.

[0080] like Figures 1-7 As shown, the air supply device 1 also includes twenty-four partition structures 60, which are disposed in the cavity 50 to form an air duct 32; the twenty-four partition structures 60 and the box-shaped outer shell 40 are integrally formed.

[0081] By setting the partition structure 60 within the cavity 50 to form the air duct 32, the design and manufacturing costs of this structure are relatively low. Compared to a split design, the connection between the partition structure 60 and the box-shaped outer shell 40, which is integrally formed, is less likely to develop gaps during use, thus preventing airflow from flowing out through gaps and causing airflow loss into the air duct 32.

[0082] like Figures 1-7 As shown, the wind deflector 20 includes a lever 21, which is disposed on the outer surface of the wind deflector 20. The lever 21 is used to drive the wind deflector 20 to move in order to switch the connection relationship between the blower outlet and the air supply port and the smoke exhaust port.

[0083] By setting the lever 21 on the outer surface of the wind deflector 20, it is convenient for users to operate the wind deflector 20 and it is more labor-saving. At the same time, the lever 21 has a short transmission path and a clear force point, which can meet the user's real-time response requirements to changes in airflow.

[0084] like Figures 1-7 As shown, in this embodiment, the box-shaped outer shell 40 is mounted on the wall via the back panel 41, corresponding to nine exhaust vents 11 at a total angle of 150 degrees, while the perforated structure 22 of the wind deflector 20 corresponds to four air supply vents 10 (or exhaust vents 11) at a total angle of 60 degrees. When the perforated structure 22 of the wind deflector 20 is aligned with the wall, the air supply vents 10 of the gas water heater 1000 are closed, which does not affect the supply of air from the fan outlet to the combustion chamber 8. The user can adjust the direction of the perforated structure 22 within a 210-degree adjustment angle range using the lever 21, so that the air supply vents 10 (or exhaust vents 11) can supply air or exhaust smoke within a 60-degree range.

[0085] In this embodiment, the air supply device 1 also includes a filter element (not shown in the figure). The filter element is disposed at the air outlet 10 and is made of ceramic material with a carbon monoxide catalyst. Therefore, it has the function of catalytically treating carbon monoxide and purifying the gas delivered from the air outlet 10. In other embodiments, the air supply device 1 is also provided with other types of purification structures to further purify the gas in the air outlet 10. This part belongs to the prior art and will not be described in detail here.

[0086] In this embodiment, the present invention also provides an air supply device 1, which is used in the gas water heater 1000 as described above.

[0087] In this embodiment, the gas water heater 1000 can be controlled by a voice module (not shown in the figure). The voice module is equipped with a controller, a voice receiving module, and a voice parsing module. The voice receiving module receives user commands, and the voice parsing module parses the commands. Based on the parsed commands, the controller controls the gas water heater 1000 to perform corresponding operations, thereby realizing intelligent control of the gas water heater 1000 and improving the user experience.

[0088] Example 2

[0089] The gas water heater in Example 2 differs from that in Example 1 in that, in this example, the blower is located below the combustion chamber, the outlet of the blower is directly connected to the air inlet of the combustion chamber, and the flue gas outlet of the combustion chamber is directly connected to the air supply device.
