Description

Technical Field

[0001] The utility model belongs to the technical field of household appliances, and particularly relates to a water storage structure for absorbing waste heat of a heat exchange device and a gas water heater. Background Art

[0002] A gas water heater is a type of gas water heater that uses gas as fuel and, through combustion and heating, transfers heat to cold water flowing through a heat exchanger to produce hot water. However, in existing technologies, the burner inside a gas water heater heats the water after heat exchange through the heat exchanger. The heat within the heat exchanger is inevitably dissipated through conduction to the surface of the heat exchanger. In other words, the heat transferred to the outside by the heat exchanger itself is still not effectively utilized. At the same time, there is a demand to further shorten the time users have to wait for hot water to be heated. Therefore, how to further improve the heat utilization rate of gas water heaters and thereby shorten the time users have to wait for hot water to be heated is a technical problem that needs to be solved urgently. Utility Model Content

[0003] To solve the above technical problems, the present application further improves the internal structure of the gas water heater, in order to further improve the heat utilization rate of the heat exchange device and thereby shorten the time users have to wait for hot water to be heated. One of the purposes of this utility model is to provide a water storage structure that absorbs the waste heat of the heat exchange device, and the second purpose is to provide a corresponding gas water heater.

[0004] The specific technical solution is described below:

[0005] The water storage structure for absorbing waste heat from a heat exchange device comprises a burner and a heat exchange device arranged on an outflow path of the burner flue gas, and further comprises:

[0006] a water storage assembly fittedly disposed outside the heat exchange device;

[0007] A water storage cavity is provided in the water storage component, and the water storage cavity is communicated with the water flow channel of the heat exchange device. The water storage component also includes a water inlet and a water outlet provided thereon.

[0008] In the above technical solution, the water storage component and the heat exchange device are arranged in close proximity, which can facilitate the absorption of heat on the surface of the heat exchange device for preheating, thereby improving the utilization rate of heat. Since the heat is absorbed by the water tank, the heated water in the water tank has reached a certain temperature, so using it for preheating hot water can shorten the time users have to wait for hot water.

[0009] Preferably, the water storage component is arranged to fit on a side wall of the heat exchange device with a larger area. The larger the fitting area is, the easier it is for the water storage component to absorb heat.

[0010] Preferably, the water inlet is arranged at the lower part of the water storage component, and the water outlet is arranged at the upper part of the water storage component. Water enters from the bottom and exits from the top, which can increase the residence time of water and absorb heat more fully.

[0011] Preferably, the water storage component also includes an electric auxiliary heating device, which assists in heating the water in the water storage chamber, thereby reducing the user's waiting time and improving the user experience.

[0012] Further preferably, the electric auxiliary heating device includes a heating tube arranged in the water storage chamber and a heating joint arranged outside the water storage chamber, and the heating tube forms a circuitous heating structure in the water storage chamber. The circuitous heating structure increases the heat exchange area and can improve the preheating speed.

[0013] Preferably, the heat exchange device and the water storage assembly form a heat exchange structure, which is mounted on the upper surface of the burner. The system further comprises a fan, which is mounted below the burner and has an upwardly directed air outlet. The system further comprises a smoke collection hood, which is mounted on the smoke outlet above the heat exchange device.

[0014] The gas water heater is internally provided with the water storage structure described in any of the above technical solutions.

[0015] In summary, the technical solution of the present invention has the following main beneficial effects:

[0016] Compared with the prior art, the water storage assembly and the heat exchange device in the technical solution of the utility model are arranged in close proximity, which can easily absorb the heat on the surface of the heat exchange device for preheating, thereby improving the utilization rate of heat. Since the heat is absorbed by the water storage tank, the heated water in the water storage tank has already reached a certain temperature. Therefore, using it to preheat hot water can shorten the time users have to wait for hot water.

[0017] At the same time, an electric auxiliary heating device is provided in the water storage component, which assists in heating the water in the water storage chamber, which can further reduce the user's waiting time and improve the user experience.

[0018] Further or more detailed beneficial effects will be described in conjunction with specific examples in the specific implementation manner. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The present invention will be further explained with reference to the following embodiments:

[0027] The core technical problem faced by the technical solution of the embodiment of the present application comes from the inventor's accurate understanding of the existing technology. Therefore, how to further utilize the heat on the surface of the heat exchange device and improve the heat exchange efficiency is a technical problem that the inventor urgently needs to solve.

[0028] At the same time, how to reduce the user's waiting time and improve the user experience is also a technical problem that the inventors are working hard to solve.

[0029] It should be noted that the embodiments do not constitute a limitation on the scope of protection of the claims of the present utility model. Based on the technical concepts provided / proven by the embodiments, all technical solutions that can be reasonably anticipated by technical personnel in the relevant technical field should be included in the scope of protection of the claims of the present utility model.

[0030] The embodiments are described in detail as follows:

[0031] In the prior art, the heat in the heat exchange device 2 is inevitably lost by conduction to the surface, and the heat conducted to the outside by the heat exchange device 2 itself is still not effectively utilized.

[0032] In addition, there is a demand to further shorten the time users have to wait for hot water to be heated;

[0033] Therefore, how to make full use of the heat exchange device 2 to dissipate the lost heat and thereby shorten the time the user waits for hot water to be heated is a technical problem that needs to be urgently solved in this embodiment.

[0034] In order to solve the above technical problems:

[0035] Please refer to the attached Figures 1 to 4The present embodiment relates to a water storage structure for absorbing waste heat from a heat exchange device, comprising a burner 3 and a heat exchange device 2 arranged on the upper surface of the burner 3, that is, on the outflow path of the flue gas of the burner 3, and further comprising a fan 4 arranged below the burner 3. The air outlet of the fan 4 is arranged upward, that is, to blow air into the burner 3. A smoke collecting hood 5 is provided at the smoke outlet above the heat exchange device 2 for collecting and discharging the smoke after heat exchange. The heat exchange device 2, burner 3, fan 4 and smoke collecting hood 5 are arranged vertically, which is convenient for arrangement in a relatively narrow gas water heater shell.

[0036] Due to the heat transfer, it is inevitable that a portion of heat will be lost on the surface of the heat exchange device 2. This embodiment aims to make the best use of this portion of heat to improve the heat utilization rate in the gas water heater.

[0037] Specifically, in this embodiment, a water storage assembly 1 is provided, and a water storage chamber 1.1 in the water storage assembly 1 is connected to a water flow channel of the heat exchange device 2. That is, the water in the water storage assembly 1 is preheated and then flows into the heat exchange device 2 for heat exchange;

[0038] The water storage component 1 is fitted on a side surface with a larger area of ​​the side of the heat exchange device 2 to absorb as much heat as possible from the heat exchange device 2. The lower part of the water storage component 1 is provided with a water inlet 1.2 and the upper part is provided with a water outlet 1.3. The water enters from the bottom and exits from the top, which can increase its residence time for more sufficient heat absorption.

[0039] In this embodiment, the water storage component 1 and the heat exchange device 2 are arranged in close proximity, which can facilitate the absorption of heat from the surface of the heat exchange device 2 for preheating, and heat exchange is carried out when the heat flows into the heat exchange device 2, thereby improving the utilization rate of heat. At the same time, since the heat is absorbed by the water storage component 1, the heated water in the water storage component 1 has reached a certain temperature, so using it for preheating of hot water can shorten the time users have to wait for hot water.

[0040] Please continue to refer to the attached Figures 1 to 4 In a preferred embodiment, the water storage assembly 1 is further provided with an electric auxiliary heating device 1.4, which includes a heating pipe 1.41 arranged in the water storage chamber 1.1 and a heating joint 1.42 arranged outside the water storage chamber 1.1. The heating pipe 1.41 forms a circuitous heating structure in the water storage chamber 1.1.

[0041] In this embodiment, the electric auxiliary heating device 1.4 assists in heating the water in the water storage chamber 1.1, which can further reduce the user's waiting time and improve the user experience. The circuitous heating structure increases the heat exchange area, which can further improve the preheating speed.
