Description

Technical Field

[0001] The utility model relates to the technical field of gas water heaters, in particular to a modular combined household gas instantaneous water heater. Background Art

[0002] In the structure of a gas water heater, there must be an exhaust port as the channel for discharging the produced gas after gas combustion. For example, the invention patent named Gas Water Heater disclosed in the Chinese Patent Application Publication No. CN117146446A on December 1, 2023, includes: a housing, a combustion chamber, a burner, a blower, and a gas supply pipe. The burner includes a plurality of burner ports. Each burner port includes a first housing and a second housing. A diversion channel and a first gas mixing zone that communicate with each other are formed in the first housing. An air inlet communicating with the diversion channel is further provided on the first housing; a plurality of first through holes and a plurality of second through holes that respectively communicate with the first gas mixing zone are further provided on the first housing; a first gas outlet cavity and a second gas outlet cavity are arranged side by side in the second housing, and a thick fire hole and a thin fire hole are provided at the top of the second housing; a second gas mixing zone is formed between two adjacent burner ports, and the second through hole, the second gas mixing zone, and the second gas outlet cavity are sequentially communicated. This simplifies the overall structure of the burner to reduce the overall manufacturing cost of the gas water heater.

[0003] As can be seen from its drawings, there is an exhaust port at the top of the gas water heater. The top exhaust port of such a gas water heater is generally integrally formed with the combustion chamber or the heat exchanger. When the gas water heater is arranged outdoors, in order to prevent sundries from entering through the exhaust port, the exhaust port is designed to exhaust forward. If the design is still based on the integrally formed exhaust port, then the design of the combustion chamber or the heat exchanger needs to be completely changed, resulting in an increase in the product design cost. Summary of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the purpose of the present utility model is as follows:

[0005] First, to provide a modular combined household gas instantaneous water heater, the exhaust port is designed separately from the combustion chamber or the heat exchanger. In actual production, only the exhaust ports with different exhaust directions and the corresponding housings need to be produced according to the order requirements.

[0006] To achieve the above purpose, the present utility model provides the following technical solution: A modular combined household gas instantaneous water heater includes a gas water heater body and a housing. A smoke collecting hood is provided at the upper part of the gas water heater body. At least one exhaust port is provided on the smoke collecting hood. The opening of the exhaust port is located at the top or the front of the gas water heater body. An air outlet corresponding to the position of the exhaust port is provided on the housing.

[0007] This solution adopts a separated design of the smoke collecting hood and the gas water heater body, ensuring that during the actual production process, the ratio of indoor gas water heaters to outdoor gas water heaters in the actual finished products can be controlled by adjusting the production ratio of the exhaust port with the opening facing the front and the smoke collecting hood with the opening facing the top, as well as producing the outer shell with corresponding air outlets.

[0008] Optionally, there is an exhaust port provided on the smoke collecting hood, the opening of the exhaust port is located at the top or the front of the gas water heater body, and there is an air outlet provided on the outer shell corresponding to the position of the exhaust port.

[0009] Optionally, the gas water heater body includes an inner shell, a water pipe, a burner, a heat exchanger, and a gas pipe. The water pipe, the burner, the heat exchanger, and the gas pipe are all arranged inside the inner shell. The gas pipe is connected to the burner, the burner is connected to the heat exchanger, one end of the water pipe is a water inlet joint, the other end of the water pipe is a water outlet joint, and the water pipe is connected to the heat exchanger.

[0010] Optionally, a flow sensor is further provided near the water inlet joint of the water pipe, and a controller is also arranged inside the inner shell. The flow sensor is electrically connected to the controller.

[0011] Optionally, an ignition device is also provided on the burner.

[0012] Optionally, an air inlet fan is also provided on the burner.

[0013] As another alternative solution, there are two exhaust ports provided on the smoke collecting hood. The two exhaust ports are respectively facing the top of the gas water heater body and the front of the gas water heater body, and there is an air outlet provided on the outer shell corresponding to any one of the two exhaust ports.

[0014] This solution adopts the same design of the smoke collecting hood, and combines the structures of the air outlets at different positions on the outer shell to achieve the effect of discharging gas from the top or the front direction of the gas water heater. In actual production, it is only necessary to produce the outer shell with different air outlets according to the order requirements.

[0015] Preferably, a heat insulation member is provided on the inner wall of the outer shell, and the heat insulation member is located between the two exhaust ports.

[0016] One end of the heat insulation member is used to seal the exhaust port without an air outlet at the corresponding outer shell, to prevent the waste gas at this exhaust port from entering between the outer shell and the water heater body, and to prevent the waste gas at this exhaust port from baking the outer shell at the corresponding position at a high temperature. The other end of the heat insulation member extends to the exhaust port with an air outlet at the corresponding outer shell, and is used to guide the heat at the exhaust port without an air outlet at the corresponding outer shell to the exhaust port with an air outlet at the corresponding outer shell and discharge it accordingly.

[0017] The beneficial technical effects of the present utility model are as follows: Through the separable design of the smoke collecting hood and the gas water heater body, the gas water heater body can be adapted to both indoor and outdoor models, thereby reducing production costs. Only by changing the smoke collecting hood and the smoke exhaust port can the purpose of switching between the indoor unit and the outdoor unit be achieved. In terms of design, the mold investment cost can be saved, the parts have high versatility, and the production cost is relatively low. Description of the Drawings
