Description

Technical Field

[0001] This utility model relates to the field of gas water heater technology, specifically to a storage-type gas water heater. Background Technology

[0002] A storage gas water heater is a device that heats and stores hot water using gas. It is suitable for high-end residences, apartments, restaurants, schools, hotels, factories, commercial office spaces, hospitals, entertainment venues, and other scenarios that require a large amount of hot water.

[0003] Chinese patent document CN214841730U discloses a storage-type commercial gas water heater. By setting up a heat transfer component, high-temperature flue gas enters the flue gas collection pipe through the flue pipe. The high-temperature flue gas in the flue pipe exchanges heat with the water in the tank body to achieve the purpose of heating the water. At the same time, the heat transfer plate conducts heat in the flue pipe and exchanges heat with the water in the tank body through the heat transfer plate, thereby improving the heat utilization rate of the high-temperature flue gas in the flue pipe and improving the heating efficiency of the water heater.

[0004] However, when the above scheme is used, when the high-temperature flue gas exchanges heat with the water in the box body in the flue pipe, some of the hot gas will be directly sent to the exhaust pipe through the flue pipe. This results in the high-temperature flue gas not being fully utilized, which limits the heat exchange efficiency, causes a large heat loss, and results in low heating efficiency.

[0033] Example 1

[0034] like Figure 1-4 As shown, the present invention proposes a storage-type gas water heater, which includes an outer shell 1, a combustion assembly, a housing, and a flow guide pipe;

[0035] The combustion assembly is located at the bottom of the outer casing 1 and is used to heat the air and transport the heated air during use. The top of the combustion assembly is provided with a heat exchange assembly for guiding the hot air generated by the combustion assembly during use and exchanging heat with the water inside the outer casing 1. During use, the air heated by the combustion assembly flows inside the outer casing 1 and exchanges heat with the water in the outer casing 1 through the heat exchange assembly, so that the water inside the outer casing 1 is heated.

[0036] The housing is installed inside the outer shell 1 and sleeved on the top of the heat exchange component. The inner wall of the housing and the outer side of the heat exchange component form a heating chamber 17, which is used to collect the gas delivered by the heat exchange component during use and heat it in the heating chamber 17.

[0037] The guide pipe is connected to the heating chamber 17 to communicate with the outside of the outer shell 1 to deliver heat exchange gas to the outside of the outer shell 1. The secondary heated air flows in the outer shell 1 and reheats the water inside the outer shell 1 through the guide pipe, thereby improving heat exchange efficiency and energy utilization.

[0038] In this embodiment, the combustion component heats the air and the heat exchange component, and the hot air moves into the air exchange component. The heat exchange component then guides the hot air to the inside of the outer shell 1, thereby allowing the heat exchange component to exchange heat between the water in the outer shell 1 and the hot air, thus heating the water. At the same time, the heat exchange component guides the heat-exchanged hot air to the heating chamber 17, reheating the heat-exchanged hot air. The hot air is then spirally moved inside the outer shell 1 through the guide pipe, allowing it to undergo secondary heat exchange, thus achieving higher heating efficiency and heating effect.

[0039] Example 2

[0040] like Figure 4 As shown, the present invention proposes a storage gas water heater. Compared with embodiment one, the difference in this embodiment is that the combustion assembly includes a mounting shell 5, a blower 6, and a burner 15.

[0041] Mounting housing 5 is installed at the bottom of housing 1;

[0042] The burner 15 is installed inside the mounting shell 5 and is arranged towards the heat exchange assembly. The bottom end of the burner 15 is provided with a gas pipe 7 that passes through the mounting shell 5. The burner 15 is existing technology and is only shown in the figure for illustration purposes.

[0043] The blower 6 is installed at the bottom of the mounting housing 5 and is arranged towards the top of the inner side of the mounting housing 5. It is used to supply air into the mounting housing 5 during use and to make the air in the mounting housing 5 flow into the heat exchange assembly.

[0044] In this embodiment, gas is supplied to the burner 15 through the gas pipe 7, so that the burner 15 can effectively burn and heat the air inside the mounting shell 5 and the bottom of the heat exchange component. The hot gas generated by combustion is introduced into the heat exchange component through the blower 6, and the mounting shell 5 continues to burn and heat the air supplied by the blower 6, so that the water inside the shell 1 can continuously exchange heat.

[0045] Example 3

[0046] like Figure 3 As shown, the present invention proposes a storage gas water heater. The difference between this embodiment and the first embodiment is that the heat exchange component includes a heat-conducting shell 9 and a heat exchange tube 11.

[0047] The heat-conducting shell 9 is installed inside the outer shell 1 and located above the burner 15;

[0048] There are multiple heat exchange tubes 11, which are arranged at equal angles on the heat-conducting shell 9. One end of the heat exchange tube 11 extends towards the inner top of the shell 1 and extends towards the shell from the inner top of the shell 1. The heat exchange tube 11 is connected to the heating chamber 17.

[0049] In an optional embodiment, fins 12 are provided on the outer side of the heat exchange tube 11. The number of fins 12 is multiple, and the multiple fins 12 are arranged at equal angles according to the center of the heat exchange tube 11 to increase the contact area between the heat exchange tube 11 and the water during use, thereby improving its heat exchange efficiency.

[0050] In this embodiment, by installing the heat-conducting shell 9 above the combustion assembly and installing multiple heat exchange tubes 11 on the heat-conducting shell 9, the air heated by the combustion assembly is transported from the heat-conducting shell 9 to the heat exchange tubes 11, and the heat exchange tubes 11 cause the hot air to flow in the outer shell 1, thereby promoting the transfer of heat from the hot air to the water, so that the water in the outer shell 1 can be heated.

[0051] Example 4

[0052] like Figure 3 As shown, the present invention proposes a storage gas water heater. Compared with embodiment one, the difference in this embodiment is that the shell includes a connecting shell 13 and a sleeve 14.

[0053] The sleeve 14 is located at the bottom inner side of the outer casing 1 and at the edge of the heat-conducting shell 9;

[0054] The connecting shell 13 is installed at the top of the sleeve 14 and connected to one end of the heat exchange tube 11.

[0055] In an optional embodiment, the outer wall of the sleeve 14 and the inner wall of the outer shell 1 form a water collection trough 16. The top and bottom of the outer shell 1 are respectively provided with a water inlet pipe 2 and a drain pipe 3. The drain pipe 3 is located at the bottom of the water collection trough 16 and is used to drain the water inside the outer shell 1 through the cooperation of the water collection trough 16 and the drain pipe 3 during use.

[0056] In an optional embodiment, the projected shapes of the heat-conducting shell 9 and the connecting shell 13 are both bowl-shaped, which increases the contact area between the heat-conducting shell 9 and the flame of the burner 15, improves the heating rate of the gas in the heating chamber 17, and guides it to the opening of the heating chamber 17 to increase the flow of the gas.

[0057] In this embodiment, a heating chamber 17 is formed by connecting shell 13, sleeve 14 and heat-conducting shell 9. The heating chamber 17 collects the heat exchanged gas and allows the gas to be reheated in the heating chamber 17 by contacting the flame of the combustion component through the heat-conducting shell 9, so that the gas can undergo secondary heat exchange and improve energy utilization.

[0058] Example 5

[0059] like Figure 3 As shown, the present invention proposes a storage gas water heater. Compared with embodiment one, the difference in this embodiment is that the guide pipe includes an exhaust pipe 4, a spiral pipe 8, and a connecting pipe 10.

[0060] The connecting pipe 10 is installed at the top of the connecting shell 13 and one end extends toward the inner wall of the outer shell 1;

[0061] The spiral tube 8 is installed at one end of the connecting pipe 10 and is located on the inner wall of the outer shell 1, sleeved on the outside of multiple heat exchange tubes 11. It is used to heat the water in the middle of the inner side and the inner wall of the outer shell 1 at the same time during use, thereby improving heating efficiency.

[0062] The exhaust pipe 4 is installed at the top of the spiral pipe 8 and one end extends through the outer casing 1 to the outside of the outer casing 1.

[0063] In this embodiment, the gas reheated in the heating chamber 17 is guided to the spiral tube 8 through the connecting pipe 10, and the spiral tube 8 moves it spirally in the outer shell 1, so that it can perform secondary heat exchange with the water inside the outer shell 1, and is discharged to the outside through the exhaust pipe 4, thereby improving the heat exchange efficiency.

[0064] In this invention, gas is supplied to the burner 15 via the gas pipe 7, enabling the burner 15 to effectively burn and heat the air inside the mounting shell 5 and the heat-conducting shell 9. The heat-conducting shell 9 heats the air inside the heating chamber 17 and heats the connecting shell 13, preheating the water inside the outer shell 1. Simultaneously, the blower 6 guides the hot gas generated by combustion through the heat-conducting shell 9 into the heat exchange tube 11. The heat exchange tube 11 is located inside the outer shell 1 and connected to the connecting shell 13, allowing the hot gas to exchange heat with the water inside the outer shell 1 as it flows through the heat exchange tube 11. The heat-exchanged gas then flows into the heating chamber 17, where the burner 15 reheats it through the heat-conducting shell 9. The gas is then guided through the connecting pipe 10 into the spiral tube 8, which moves spirally within the outer shell 1, maximizing the efficiency of heat exchange and allowing heat exchange to occur simultaneously at multiple locations within the outer shell 1. This improves the heating efficiency of the water in the outer shell 1 and maximizes energy utilization.

Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
