Description
Technical Field
[0001] The utility model relates to the technical field of gas heating and hot water boilers, in particular to a gas heating and hot water boiler with an auxiliary heat source heating and a heating system thereof. Background Art
[0002] A gas heating and hot water boiler, also known as a "gas wall-mounted heating boiler" or a "wall-mounted boiler", is a fast heating device without a hot water storage device, just like a gas instantaneous water heater, but there are essential differences in structure. Different from a water heater, a gas heating and hot water boiler has the dual functions of heating and supplying hot water, which can not only meet the heating needs of multiple rooms but also take into account the hot water bathing needs.
[0003] In daily heating operation, the heating circulation system keeps the heating water circulating under the action of a heating pump. When the temperature of the heating water drops to the starting set temperature, the heating system of the hot water boiler will be started to raise the temperature of the heating water. Generally, in order to avoid frequent start-up of the hot water boiler, the starting set temperature is set to a lower temperature, or the stopping temperature is set to a higher temperature, increasing the heating temperature difference, so that the hot water boiler can run for a period of time and then stop running, reducing the running frequency of the hot water boiler. However, after such setting, the indoor temperature will fluctuate greatly, affecting the comfort of heating. Otherwise, frequent start-up of the hot water boiler is likely to cause over-temperature flameout of the hot water boiler, which not only affects the service life of the hot water boiler but also wastes gas and increases the cost of users.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0025] In order to make the above objects, features, and advantages of the present utility model more obvious and understandable, the following detailed description of the specific embodiments of the present utility model will be given with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.
[0026] In the description of the present utility model, it should be understood that the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of the present utility model, the meaning of "a plurality of" is at least two, such as two, three, etc., unless otherwise specifically defined.
[0027] In the description of the present utility model, it should be understood that when an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be intermediate elements present simultaneously. In contrast, when an element is referred to as being "directly" connected to another element, there are no intermediate elements.
[0028] Please refer to Figures 1-3 , which is a gas-fired heating and hot water boiler of a preferred embodiment of the present utility model, used to be connected to a heating terminal and a sanitary terminal to supply sanitary hot water and heating water to users. Among them, an auxiliary heat source is cooperated to perform auxiliary heating. The auxiliary heat source is a small-power heating device that can supplement the small temperature fluctuations during the heating process, such as different heating fluctuations during day and night, or small temperature fluctuations during the day, so as to reduce the frequent startup of the hot water boiler. Specifically, the gas-fired heating and hot water boiler includes a main heat exchanger 10, a blower 11, a Venturi tube 12, a burner 13, a gas valve 14, an electromagnetic three-way valve 15, a heating NTC 16, a plate heat exchanger 17, a sanitary NTC 18, a water pump 19, a water flow sensor 20, a heating outlet pipe 21, a heating return pipe 22, a sanitary hot water pipe 23, a tap water pipe 24 and an auxiliary heat source system 30.
[0029] The burner 13 is communicated with the Venturi tube 12, the blower 11 and the gas valve 14. Through the action of the blower 11, the gas and air are sufficiently mixed in the Venturi tube 12, and then the mixed gas is drawn into the burner 13 for ignition and combustion to heat the system water in the main heat exchanger 10.
[0030] The water pump 19, the main heat exchanger 10, the heating end of the electromagnetic three-way valve 15, the heating outlet pipe 21, the heating terminal and the heating return pipe 22 are connected to form a heating cycle. Among them, the auxiliary heat source system 30 is installed between the water pump 19 and the main heat exchanger 10, which can reduce the influence of the hot water heated by the main heat exchanger 10 on the auxiliary heat source system 30; the heating NTC 16 is installed on the heating outlet pipe 21. According to the heating outlet water temperature detected by the heating NTC 16, if the required heating power or temperature difference is small, the auxiliary heat source system 30 is started for heating, and if the required heating power or temperature difference is large, the hot water boiler is started.
[0031] The bathroom end of the water pump 19, the main heat exchanger 10, and the electromagnetic three-way valve 15 is connected to the heating end of the plate heat exchanger 17 to form a bathroom heating cycle, heating the bathroom water in the other end of the plate heat exchanger 17.
[0032] The tap water pipe 24, the heat exchange end of the plate heat exchanger 17, and the bathroom hot water pipe 23 are connected to form a bathroom water heating system. One end of the bathroom water heating system is connected to the bathroom end. The bathroom NTC 18 is installed on the bathroom hot water pipe 23, and the water flow sensor 20 is installed on the tap water pipe 24. When water flow is detected and the water flow rate is greater than the set flow rate value, the hot water furnace is started, and the bathroom heating cycle is turned on. Through the plate heat exchanger 17, the bathroom water heating system is heated to output hot water that meets the user's needs. Among them, the auxiliary heat source system 30 is installed between the water pump 19 and the main heat exchanger 10. Since the required heating power or temperature difference is large, only the hot water furnace needs to be started.
[0033] In one embodiment, the auxiliary heat source system 30 is one of a central heating hot water system, a solar hot water system, a heat pump hot water system, and an electric heating hot water system.
[0034] When the auxiliary heat source system 30 is a central heating hot water system or a solar hot water system or a heat pump hot water system, the auxiliary heat source system 30 includes an auxiliary heat source heat exchanger 31, a heat source inlet pipe 32, a heat source outlet pipe 33, an auxiliary heat source NTC 34, a water flow regulating valve 35, and an electromagnetic switch valve 36. The auxiliary heat source heat exchanger 31 is a plate-type heat exchanger. The heat exchange ends of the auxiliary heat source heat exchanger 31 are respectively connected to the water pump 19 and the main heat exchanger 10. The heat source ends of the auxiliary heat source heat exchanger 31 are respectively connected to the heat source inlet pipe 32 and the heat source outlet pipe 33. The electromagnetic switch valve 36, the water flow regulating valve 35, and the auxiliary heat source NTC 34 are installed on the heat source inlet pipe 32 in sequence along the water flow direction. According to the temperature detected by the auxiliary heat source NTC 34, through the adjustment and control of components such as the electromagnetic switch valve 36 and the water flow regulating valve 35, precise control of the auxiliary heat source heating temperature is achieved. The heat source inlet pipe 32 and the heat source outlet pipe 33 are respectively connected to the water supply end and the return water end of the central heating hot water system or the solar hot water system or the heat pump hot water system. The main machines of systems such as the solar hot water system or the heat pump hot water system are installed in other places of the hot water furnace and are connected through the heat source inlet pipe 32 and the heat source outlet pipe 33.

A heat exchange coil is provided inside the auxiliary heat source heat exchanger 31, and the electric heating device is wound around the heat exchange coil. Both ends of the heat exchange coil are respectively connected to a water pump 19 and a main heat exchanger 10. The electric heating device is an electric heating tape or an electric heating wire. According to the startup requirement, the electric heating device is started to heat the water in the heat exchange coil. When the electric heating device is an electric heating tape, the auxiliary heat source heat exchanger 31 has a receiving cavity, and the air can be used to separate the electric heating tape from the inner wall of the auxiliary heat source heat exchanger 31. When the electric heating device is an electric heating wire, the auxiliary heat source heat exchanger 31 is filled with water, and the electric heating wire is wound around the heat exchange coil. The heat can also be indirectly transferred through the water to uniformly heat the water in the heat exchange coil.
[0036] In the above structure, the connections between the water pump 19, the main heat exchanger 10 and the auxiliary heat source heat exchanger 31 are plug-in type and are sealed by O-ring seals.
[0037] In some other embodiments, the present utility model further provides a heating system, which includes a gas-fired heating hot water boiler, a heating terminal and a sanitary terminal connected to the gas-fired heating hot water boiler. The gas-fired heating hot water boiler includes a main heat exchanger 10, a blower 11, a Venturi tube 12, a burner 13, a gas valve 14, an electromagnetic three-way valve 15, a heating NTC 16, a plate heat exchanger 17, a sanitary NTC 18, a water pump 19, a water flow sensor 20, a heating outlet pipe 21, a heating return pipe 22, a sanitary hot water pipe 23, a tap water pipe 24 and an auxiliary heat source system 30. The auxiliary heat source system 30 is installed between the water pump 19 and the main heat exchanger 10. By adding a set of auxiliary heat source system 30 between the water pump 19 and the main heat exchanger 10, when the heating power or temperature difference required for heating is small, the auxiliary heat source system 30 is started for auxiliary heating to realize auxiliary heat source heating and heating. It can not only provide comfortable heating for users, but also extend the service life of the hot water boiler and avoid frequent startup of the hot water boiler.

The heating NTC 16 is installed on the heating outlet pipe 21. When the heating power or temperature difference required by the heating terminal is small (the set minimum power or temperature difference), the auxiliary heating of the auxiliary heat source system 30 is started.
[0039] In the bathroom heating mode, the water pump 19, the auxiliary heat source system 30, the main heat exchanger 10, the bathroom end of the electromagnetic three-way valve 15, and the heating end of the plate heat exchanger 17 are connected to form a bathroom heating cycle, and the auxiliary heat source system 30 is not started.

One end of the bathroom water heating system is connected to the bathroom end, the bathroom NTC 18 is installed on the bathroom hot water pipe 23, and the water flow sensor 20 is installed on the tap water pipe 24.
[0040] The technical features of the above-described embodiments can be combined arbitrarily.
