With the increasing popularization of gas water heaters, the importance of the use safety of the gas water heaters is increasingly highlighted. In the operation process of the gas water heater, if the flue is blocked, the combustion working condition of the gas water heater is not ideal, harmful smoke is generated, and the use safety of the gas water heater is reduced. For this reason, the existing gas water heater can identify whether the flue is blocked or not through the pressure sensor. However, the existing gas water heater cannot further know whether the heat exchange device at the flue has a blockage fault, so that the troubleshooting efficiency of the blockage fault is reduced.

In view of the above, the present invention provides a burner that can be applied, for example, on a water heater. The water heater can be a product and equipment which uses gas combustion to generate high-temperature hot water for household bathing, heating and the like.

Referring to fig. 1 to 5, an embodiment of the burner of the present invention applied to a gas water heater is shown in the drawings.

Referring to fig. 1 to 2, the burner 100 provided by the present invention includes a combustion body, a heat exchange device 200 and two pressure nozzles 311. Wherein the combustion body is formed with a chamber 110 for gas to flow through, the chamber 110 comprising a heat exchange chamber 113; the heat exchange device 200 is arranged in the heat exchange chamber 113 to divide the cavity 110 into a first cavity section 110a and a second cavity section 110b which are sequentially communicated along the airflow direction; the two pressure taking nozzles 311 are disposed in the chamber 110, and are respectively disposed in the first cavity segment 110a and the second cavity segment 110b, and the two pressure taking nozzles 311 are used for being connected with the wind pressure detecting device 300.

In the technical scheme provided by the utility model, a chamber 110 formed by a combustion main body is communicated with a flue or forms at least part of the flue; the chamber 110 comprises a heat exchange chamber 113 for installing the heat exchange device 200, so that the high-temperature flue gas passes through the heat exchange device 200 in the flowing process; two pressure taking nozzles 311 are respectively located the relative both sides of heat transfer device 200 in the air current direction, can detect out the first pressure value before heat transfer device 200 respectively, and the second pressure value behind heat transfer device 200 to supply wind pressure detection device 300 according to first pressure value and second pressure value, whether discernment flue and heat transfer device 200 are out of order, help flue and heat transfer device 200's out of order timely discovery and solve in time, improve the use quality of combustor 100.

It will be appreciated that the combustion body generally comprises a housing 101, the interior of said housing 101 defining a chamber 110, the specific form of said chamber 110 being not limited and can be provided in any suitable shape, size and extension direction, etc. according to the actual needs. For example, in the present embodiment, when the combustion main body is disposed to extend substantially in the up-down direction, an outlet may be disposed in an upper region of the combustion main body, an inlet may be disposed in a lower region of the combustion main body, and the chamber 110 may extend substantially in the up-down direction in the combustion main body, so that after the gas enters the chamber 110, high-temperature flue gas generated by combustion may flow upward along the same direction and be discharged through the outlet.

Specifically, the chamber 110 includes a heat exchange chamber 113, and the heat exchange chamber 113 is a space where heat exchange mainly occurs; the burner 100 is provided with a heat exchange device 200 in the heat exchange chamber 113, the heat exchange device 200 includes, for example, a heat exchange pipe, the heat exchange pipe circulates external tap water, so that the tap water exchanges heat with high-temperature flue gas flowing in the heat exchange chamber 113 to raise the temperature when passing through the heat exchange chamber 113, thereby achieving the purpose of preparing hot water.

The heat exchange tube can be formed by a whole tube body, and can also be formed by a plurality of tube bodies together. When the heat exchange tube is composed of a whole tube body, the heat exchange tube can be at least partially straight or bent. Specifically, for example, the heat exchange tubes may extend spirally along the circumferential direction of the heat exchange chamber 113. When the heat exchange tube is composed of a plurality of tube bodies, the plurality of tube bodies may be independently provided, or at least two tube bodies among the plurality of tube bodies may be provided in communication with each other.

In the chamber 110, the heat exchanging device 200 is generally disposed at an interval from the inlet and the outlet of the chamber 110, so that the chamber 110 can be divided into a first cavity section 110a and a second cavity section 110b by the heat exchanging device 200, which are sequentially communicated in the airflow direction, for example, in this embodiment, the cavity section of the chamber 110 located below the heat exchanging device 200 constitutes the first cavity section 110a, and the cavity section of the chamber 110 located above the heat exchanging device 200 constitutes the second cavity section 110 b.

The two pressure taking nozzles 311 are respectively disposed in the first cavity segment 110a and the second cavity segment 110b, for convenience of understanding, in the following and above embodiments, the pressure taking nozzle 311 disposed in the first cavity segment 110a is named as a first pressure taking nozzle 311a, the pressure taking nozzle 311 disposed in the second cavity segment 110b is named as a second pressure taking nozzle 311b, and a pressure value of the first cavity segment 110a sensed by the first pressure taking nozzle 311a is a first pressure value, and a pressure value of the second cavity segment 110b sensed by the second pressure taking nozzle 311b is a second pressure value.

The burner 100 or the water heater 1 generally further includes a wind pressure detecting device 300, and the wind pressure detecting device 300 includes a detecting body 310. The detection main body 310 generally has two detection ports, and the two detection ports are connected to the two pressure taking nozzles 311 in a one-to-one correspondence manner to collect the first pressure value and the second pressure value respectively.

The wind pressure detecting device 300 generally further includes a control component 320, the control component 320 is electrically connected to the detecting main body 310, so as to receive the first pressure value and the second pressure value collected by the detecting main body 310, and the first pressure value and the second pressure value are analyzed and compared according to a set algorithm, thereby achieving the purpose of identifying the flue fault and the heat exchanging device 200 fault.

It is understood that the control unit 320 may be provided separately and specifically for the detection body 310, and electrically connected to the control device inherent to the water heater 1; alternatively, the control unit 320 may be provided integrally with a control device unique to the water heater 1, and the control unit 320 may constitute a part of the control device.

In the present design, the control component 320 may identify a fault state of the flue according to the received first pressure value and/or second pressure value, where the fault state includes a fault type, a fault degree value, and the like. Specifically, taking the first pressure value as an example:

in an embodiment, after the burner 100 is assembled, the control component 320 determines a calibrated pressure value according to the current application environment of the burner 100 by instant sensing through the first pressure taking nozzle 311a or by querying a database, where the calibrated pressure value may be the same as the pressure value in the first cavity segment 110a, or the pressure value outside the first cavity segment 110a but related to the pressure value in the first cavity segment 110 a. The control unit 320 stores the calibration pressure value, compares the pressure value in the chamber with the calibration pressure value when receiving the pressure value in the chamber measured in real time, determines the fault state of the burner 100 according to the comparison result, and generates a control command matched with the fault state according to the fault state.

It can be understood that when the flue of the water heater 1 is blocked or is affected by wind blockage such as inward blowing, the pressure value in the cavity becomes large. Therefore, when the pressure value in the cavity is judged to be larger than the calibrated pressure value, the water heater 1 can be determined to be in the wind blockage fault at present.

On the contrary, when the flue of the water heater 1 is lengthened or is influenced by air draft such as a public flue, the pressure value in the cavity is reduced. Therefore, when the pressure value in the cavity is judged to be smaller than the calibration pressure value, the water heater 1 can be determined to be in the air draft fault at present.

In another embodiment, after the water heater 1 is actually put into use, the first pressure taking nozzle 311a senses and obtains the pressure value in the cavity in real time and sends the pressure value to the control component 320. Each pressure value in the cavity corresponds to a time stamp, the control unit 320 compares at least two pressure values in the cavity collected successively according to a set period, determines a fault state of the combustor 100 according to a comparison result, and generates a control instruction matched with the fault state according to the fault state.

It can be understood that when the difference value between the two pressure values in the cavities is greater than the preset difference value, and the pressure value in the next cavity is greater than the pressure value in the previous cavity, it can be determined that the water heater 1 is currently in a wind blockage fault; on the contrary, when the difference between the two pressure values in the cavity is greater than the preset difference and the pressure value in the next cavity is smaller than the pressure value in the previous cavity, the current position of the water heater 1 in the air draft fault can be determined.

The method of determining the combustion state of the burner 100, that is, the fault state of the flue by using the second pressure value is referred to above and will not be described in detail.

In addition, in the present design, the control component 320 may identify a fault state of the heat exchange device 200 according to the received first and second pressure values, where the fault state includes a fault type, a fault degree value, and the like.

It will be appreciated that when the heat exchange device 200 condenses condensed water, produces verdigris and/or carbon deposits, etc., and is severe enough, it is likely to cause the chamber 110 to be clogged at the heat exchange device 200, i.e., the heat exchange device 200 is clogged as described above. At this time, the gas flowing through the first cavity segment 110a is difficult to pass through the heat exchange device 200, resulting in a greater wind pressure in the first cavity segment 110a than in the second cavity segment 110 b. Therefore, when the control component 320 compares that the first pressure value is greater than the second pressure value, and the difference between the first pressure value and the second pressure value is greater than the preset threshold, it may be basically determined that the combustor 100 is currently in the blockage failure of the heat exchange device 200.

The burner 100 or the water heater 1 generally further includes a prompting device, and the prompting device is electrically connected to the control unit 320. When the control component 320 determines that the combustor 100 is in a blockage fault of the heat exchange device 200, a control instruction is generated and sent to the prompting device, and the prompting device works according to the control instruction when receiving the control instruction.

It is understood that the control instructions generally include a power-on instruction for controlling the start of the prompting device and a prompting scheme associated with the current fault type and/or fault degree value in a one-to-one correspondence manner. The prompting scheme appears different according to different types of prompting devices. The prompting device can send out voice prompt, image prompt and the like according to actual needs, for example, the prompting device can be a breathing lamp, a buzzer, a display screen and the like; alternatively, the prompting device may be a client terminal wirelessly connected to the control unit 320, such as a mobile phone, to prompt the user to check for fault abnormality of the water heater 1 in time.

As can be seen from the above, the detection main body 310 is generally provided with two detection ports. In an embodiment, the detecting body 310 may be a differential pressure sensor, and the differential pressure sensor has two detecting ports for respectively acquiring the first pressure value and the second pressure value and obtaining a differential pressure between the first pressure value and the second pressure value.

Of course, in another embodiment, the detecting body 310 may be two absolute pressure sensors, and each of the absolute pressure sensors is provided with one of the detecting ports. At this time, the control unit 320 receives the first pressure value and the second pressure value of the two absolute pressure sensors, respectively, and calculates a pressure difference therebetween.

When the pressure measuring nozzle 311 is spaced from the corresponding detection port by a certain distance, the pressure measuring nozzle 311 and the detection port need to be communicated through a conduit. In an embodiment, the wind pressure detecting apparatus 300 further includes a conduit connecting the detecting port of the detecting body 310 and the pressure taking nozzle 311.

The duct may be a rigid pipe, the rigid pipe is designed as a straight pipe or a bent pipe bent in a desired direction, and the rigid pipe may be fixedly connected to the housing 101 at the location of the rigid pipe and may also support the detection main body 310 to strengthen the stability of the installation of the wind pressure detection apparatus 300 at the housing 101.

Of course, in one embodiment, at least a portion of the catheter is flexibly bendable. The conduit can be made of flexible materials in the whole, so that the conduit can be bent in the whole in a manner of adapting to the installation environment; the conduit may also be provided with a portion of the tube sections made of a flexible material and the remaining tube sections made of a rigid material, so that the conduit is capable of both adapting to a certain installation environment by bending and having sufficient strength. The flexible material is not limited and may be, for example, rubber, cotton, or the like.

Further, in an embodiment, at least a part of the conduit is elastically arranged. The conduit may be formed entirely of an elastic material, or may be formed with portions of the tube section of an elastic material, with the remaining tube section of a non-elastic material, in a similar manner to that described above. Therefore, at least part of the pipe section of the conduit can be stretched, compressed and bent under the action of external force, and the conduit is more suitable for different installation environments; and when at least part of the pipe section of the conduit is clamped between two components of the water heater 1, the conduit can also be used as a buffer between the two components.

It is understood that the gas circulating in the chamber 110 may be externally-accessed gas before combustion, such as combustion-supporting gas such as air, fuel such as gas; of course, the gas may also be a gas generated after combustion, such as a high temperature flue gas. When the first cavity section 110a and the second cavity section 110b are different in specific schemes, the characteristics of the wind pressure sensed by the two pressure taking nozzles 311 are different accordingly.

Referring to fig. 1 to fig. 2, in an embodiment, the heat exchange device 200 is disposed in a middle area of the heat exchange chamber 113, and directly divides the heat exchange chamber 113 into two cavity segments, i.e., the first cavity segment 110a and the second cavity segment 110b, and the two pressure taking nozzles 311 are disposed in the heat exchange chamber 113 and respectively disposed on two opposite sides of the heat exchange device 200 along an airflow direction. Therefore, the two pressure taking nozzles 311 can be intensively arranged at the same position of the combustion main body and are arranged closer to the heat exchange device 200, so that the pressure taking results of the two pressure taking nozzles 311 are prevented from being influenced by the blockage of other components in the chamber 110, and the detection accuracy is reduced.

In an embodiment, the first cavity segment 110a includes a combustion chamber 112, the combustion chamber 112 is sequentially communicated with the heat exchange chamber 113 along an airflow direction, and the first pressure taking nozzle 311a is disposed in the combustion chamber 112.

The combustion chamber 112 is used to provide sufficient space for combustion. It is understood that the combustion chamber 112 has an inlet end and an outlet end, the inlet end is provided for at least one of the combustion-supporting gases to enter, and after the combustion-supporting gases flow through the combustion chamber 112 and are combusted, the high-temperature flue gas generated is discharged from the outlet end.

The air inlet end and the smoke outlet end can be formed at any position of the combustion chamber 112, for example, in an embodiment, the air inlet end and the smoke outlet end can be oppositely arranged at two sides of the combustion chamber 112, which helps to form a sufficiently long circulation path in a limited space of the combustion chamber 112 for combustion-supporting gas to be more sufficiently and effectively combusted to generate sufficient high-temperature smoke.

Next, the burner 100 may further include a combustion assembly 116, and the combustion assembly 116 is disposed in the combustion chamber 112 near the inlet end for combustion under the flow of combustion gases. The combustion assembly 116 includes a fire bank. The specific expression form of the fire grate is not limited in the design and can be selected according to actual needs. The combustion assembly 116 may also include an ignition operation to ignite the bank of fire, a temperature sensor to sense the temperature of the combustion chamber 112, and the like.

The combustion chamber 112 may be integrated with the heat exchange chamber 113, for example, the combustion assembly 116 is disposed at one end of the heat exchange chamber 113, and the heat exchange device 200 is disposed at the other end of the heat exchange chamber 113.

Based on the above, the first cavity segment 110a includes the combustion chamber 112, and the first pressure extraction nozzle 311a may be specifically disposed in the combustion chamber 112. The first pressure extraction nozzle 311a may be disposed at any position of the combustion chamber 112, for example, at any side portion of the combustion chamber 112, and/or at an air inlet end and a smoke outlet end of the combustion chamber 112. Wherein, because the combustion chamber 112 is mainly used for combustion, in an operating state, the temperature in the combustion chamber 112 is high, and there may be non-uniform combustion-supporting gas and/or high-temperature flue gas in a local area, which results in an unstable gas flow, so that when the first pressure taking nozzle 311a is disposed in or at the side of the combustion chamber 112, the pressure taking result may be affected by the high-temperature or non-uniform gas flow to reduce the accuracy, and a corresponding compensation correction is required. Therefore, in a further scheme, the first pressure extraction nozzle 311a can be arranged near the air inlet end of the combustion chamber 112 and/or near the smoke outlet end of the combustion chamber 112.

In an embodiment, the first cavity segment 110a includes an air inlet chamber 111 and a combustion chamber 112, the air inlet chamber 111, the combustion chamber 112 and the heat exchange chamber 113 are sequentially communicated along an air flow direction, and the first pressure taking nozzle 311a is disposed in the air inlet chamber 111.

The air inlet chamber 111 is used for introducing at least one combustion-supporting gas into the combustion chamber 112, and the combustion chamber 112 is used for forming a sufficient space for combustion. When the burner 100 includes the combustion assembly 116 as described above, the combustion assembly 116 may be disposed in communication between the intake chamber 111 and the combustion chamber 112, i.e., at the outlet of the intake chamber 111 and at the intake end of the combustion chamber 112.

When the combustion gas comprises air and gas, the inlet chamber 111 may be used for accessing the air and/or the gas. Wherein, when the air inlet chamber 111 is used for accessing one of the air and the gas, the other of the air and the gas can be accessed through other structures.

Based on the above, the first pressure taking nozzle 311a may be disposed in the air intake chamber 111. Specifically, the air inlet chamber 111 may be disposed at a side portion thereof, and/or at an end of the air inlet chamber 111 away from the combustion chamber 112, for the purpose of measuring the air pressure at the location.

In an embodiment, the second cavity segment 110b includes a smoke collecting chamber 114, the heat exchange chamber 113 is sequentially communicated with the smoke collecting chamber 114 along an airflow direction, and a ventilation cross section of the smoke collecting chamber 114 is gradually reduced in a direction away from the heat exchange chamber 113; the second pressure taking nozzle 311b is provided in the smoke collecting chamber 114.

The smoke collecting chamber 114 is used for collecting high-temperature smoke generated by the combustion of the combustion chamber 112 so as to be discharged in a centralized manner or exchange heat in a centralized manner. The smoke-collecting chamber 114 is arranged to taper in a direction away from the combustion chamber 112. Specifically, for example, at least one side wall surface of the smoke collecting chamber 114 is inclined toward the other side wall surface in a direction away from the combustion chamber 112, so that the ventilation section of the smoke collecting chamber 114 is reduced or gradually reduced in the flow direction of the smoke, thereby achieving the purpose of collecting the smoke and facilitating the concentrated discharge of the smoke.
