The wall-mounted boiler is a gas heating water heater for short, and is a machine which takes natural gas as energy and integrates heating and hot water into a whole. Generally, the operating principle of the wall-hanging stove heating function is as follows: after the system is started, the system starts self-checking, the circulating water pump is started, and the system water starts to circulate. Because the flow of water generates pressure difference between two sides of the pressure difference disc, the thimble is pushed to close the pressure switch, and the fan starts to operate. After the fan operates, wind pressure difference is generated, so that the wind pressure switch is closed, the igniter starts to strike fire, the gas valve is opened, and the gas source is switched on. When the gas is ignited and combusted by spark, the main control board detects a flame signal through the fire detecting needle, if the flame signal exists, the main control board outputs control voltage to enable the electromagnetic valve to be kept open, and the combustion system conducts normal combustion. High-temperature smoke generated by combustion heats water in the heating system through the main heat exchanger, the heated water flows through a radiator arranged indoors under the driving of a water pump, and heat is dissipated indoors through the radiator, so that the room temperature is raised, and the purpose of heating is achieved.

Therefore, the wall-mounted furnace combustion system can normally burn without injecting the mixture of gas and air in the combustor. After being sprayed out from the nozzle, the mixed premixed gas is ignited and burnt at the moment of high-voltage discharge of the ignition needle. During the combustion process of the gas which is not completely combusted, the whole combustion process is fully and completely combusted in the combustion chamber due to the continuous supply of air. The produced flue gas of burning back is sent to outdoor under passing through the fan drive, keeps "negative pressure" state in the operation in-process cavity of whole machine all the time for the air can be constantly sent to the cavity from the outside in, with the abundant burning use of once drawing the air of penetrating and air supply in the combustion process for supplying with, make whole combustion process can both fully burn completely.

In the related art, the air intake and the smoke exhaust of the wall-mounted furnace cannot be automatically adjusted. In order to solve the problem in some related technologies, a variable frequency fan is used for controlling the rotating speed, and different rotating speeds are matched through different combustion loads so as to adapt to operation under the optimal condition. So, realize different combustion load and can adjust different discharge fume volume, make in the whole cavity "negative pressure" size change according to the frequency conversion fan rotational speed to reach the size of control intake, in order to reach hanging stove service environment's balance. However, the frequency conversion fan is relatively expensive, and finally the overall cost of the product is increased. In other related technologies, the air inlet amount is controlled and adjusted by assembling smoke exhaust pipe gaskets of different specifications, namely, the smoke exhaust pipe gaskets with different sizes and diameters of air inlet rings are adopted for wall-mounted furnaces with different loads. But this mode also needs the rotational speed of cooperation fan to match just can reach balanced effect, also has the tub gasket of discharging fume of many specifications simultaneously in the use, and the specification is makeed mistakes very easily to appear in assembly and use, leads to hanging stove use in the serious problem of appearing.

The embodiment of the present application takes a wall-hanging stove as an example, and the structure of the wall-hanging stove in the present application is described.

For ease of understanding, as shown in fig. 1, the direction of the corresponding side of the smoke exhaust outlet 510 of the smoke exhaust duct 500 in the wall-hanging oven is defined as the rear side. The side of the wall-mounted boiler corresponding to the rear side is the front side. As shown in fig. 1, the upper side of the drawing sheet is defined as the upper side, the lower side of the drawing sheet is defined as the lower side, the drawing sheet is defined inward as the left side, and the drawing sheet is defined outward as the right side. Subsequent figures follow the definitions of fig. 1. It is to be understood that the above definitions are for illustration purposes only and are not to be construed as limitations of the present application. It is to be understood that the above definitions are for illustration purposes only and are not to be construed as limitations of the present application.

Referring to fig. 1 to 3, an embodiment of the present application provides a wall-hanging stove, which includes a wall-hanging stove body 100, a combustion system 200, a main heat exchanger 300, a fan system 400, a smoke exhaust duct 500, and an adjusting assembly 600. The fireplace body 100 is provided with an opening 110. The smoke exhaust duct 500 is located inside the wall-hanging stove body 100. Along the first direction a, an orthographic projection of the smoke evacuation outlet 510 of the smoke evacuation duct 500 is located within an orthographic projection of the opening 110, the smoke evacuation outlet 510 and the opening 110 defining the fluid inlet 111 therebetween. The adjusting assembly 600 includes two adjusting members 610 disposed opposite to each other and a driving device 620 drivingly connecting the two adjusting members 610. The two regulating members 610 can open or close the fluid inlet 111 when moving in a direction away from or close to each other. The driving device 620 is used to drive the two adjusting members 610 to move so as to adjust the opening area of the two adjusting members 610 for opening the fluid inlet 111.

In the wall hanging stove, through setting up two regulating parts 610 that can keep away from each other or be close to each other's direction motion, can adjust the open area that opens fluid entry 111, not only can satisfy the supply of air, reach inside air current balance, help satisfying the big load ratio burning operating mode, simple structure is convenient for adjust moreover, has reduced product cost.

The first direction a is a front-rear direction illustrated in fig. 1. The orthographic projection of the smoke exhaust outlet 510 is located in the orthographic projection of the opening 110, that is, a gap exists between the smoke exhaust duct 500 and the opening 110, and the pipe diameter of the smoke exhaust duct 500 is smaller than the caliber of the opening 110. That is, since there is a gap between the smoke exhaust outlet 510 and the opening 110, that is, an inlet for the fluid is defined, the fluid enters the interior of the wall-hanging stove from the gap. It should be further noted that the wall-hanging stove body 100 refers to a box structure of the upper half portion shown in fig. 1, a containing cavity which can be closed is arranged in the wall-hanging stove body 100, and the combustion system 200, the main heat exchanger 300, the fan system 400, the smoke exhaust duct 500 and the adjusting assembly 600 are all arranged in the containing cavity.

The components in the embodiments of the present application will be described below with reference to the drawings.

With continuing reference to fig. 1-3, it is understood that fig. 2 and 3 are schematic rear views of fig. 1. In some embodiments, as shown in fig. 1, the adjusting assembly 600 is located in the wall-hanging stove body 100, so that the space in the wall-hanging stove body 100 can be fully utilized for assembly. As shown in fig. 2, the two adjustment members 610 have a first state abutting against the smoke exhaust duct 500 to close the fluid inlet 111. As shown in FIG. 3, the two adjustment members 610 have a second state separated from the smoke exhaust duct 500 to open the fluid inlet 111. That is, when the two adjusting members 610 abut against the smoke exhaust duct 500, the fluid inlet 111 is closed, and when the two adjusting members 610 are separated from the smoke exhaust duct 500, the fluid inlet 111 is opened. The opening area of the fluid inlet 111 is adjusted by using the position relationship between the two adjusting pieces 610 and the smoke exhaust duct 500, and the structure is simple, stable and reliable.

Fig. 4 is a partial schematic structural view of an adjusting assembly 600 in an embodiment of the present application, and fig. 4 is a schematic structural view of an adjusting member 610 of the adjusting assembly 600; for convenience of explanation, only portions related to the embodiments of the present application are shown.

Referring to fig. 4 in conjunction with fig. 2 and 3, in some embodiments, each of the two adjusting members 610 includes an abutting surface 611. When the two adjusting members 610 are in the first state, the two abutting surfaces 611 surround to form abutting parts matched with the smoke exhaust duct 500, so as to seal the fluid inlet 111. It will be appreciated that the abutment surface 611 is adapted to the shape of the smoke evacuation duct 500. For example, the smoke exhaust duct 500 illustrated in fig. 2 to 4 is circular, and both the abutment surfaces 611 are semicircular, constituting an abutment portion having a circular contour that contacts the smoke exhaust duct 500. For another example, when the smoke exhaust duct 500 is square, the two contact surfaces 611 constitute a contact portion having a square outline and coming into contact with the smoke exhaust duct 500. The shapes of the abutting surface 611 and the smoke exhaust duct 500 may be designed according to actual use requirements, and this is not particularly limited in the embodiment of the present application. In this way, by providing two abutting surfaces 611 matched with the smoke exhaust duct 500, each adjusting piece 610 and the smoke exhaust duct 500 have a stable positional relationship, which facilitates adjustment of the opening area of the fluid inlet 111.

With continued reference to fig. 4, in some embodiments, the driving device 620 includes two driving members 621 for driving the two adjusting members 610, the two driving members 621 correspond to the two adjusting members 610 one by one, and the driving directions of the two driving members 621 are opposite. For example, fig. 2 and 3 illustrate a situation in which the adjusting members 610 are driven to move in the left-right direction, when the two adjusting members 610 change from the first state to the second state, the left driving member 621 moves to the left, the right driving member 621 moves to the right, the left adjusting member 610 moves to the left under the driving of the left driving member 621, and the right adjusting member 610 moves to the right under the driving of the right driving member 621. That is, the left-side regulating member 610 and the right-side regulating member 610 move away from each other, and the fluid inlet 111 is opened; when the two adjusting members 610 change from the second state to the first state, the left driving member 621 moves to the right, the right driving member 621 moves to the left, the left adjusting member 610 moves to the right under the driving of the left driving member 621, and the right adjusting member 610 moves to the left under the driving of the right driving member 621, that is, the left adjusting member 610 and the right adjusting member 610 move toward each other, and the fluid inlet 111 is closed. In this way, the two driving members 621 with opposite driving directions are used to move the two adjusting members 610 away from or close to each other.

In some embodiments, as shown in fig. 4, the driving member 621 is a telescopic rod. In some embodiments, the telescopic rod is any one of an electric push rod, an electro-hydraulic push rod, a pneumatic push rod and a hydraulic push rod. When the driving member 621 is extended, the two adjusting members 610 move toward each other, and when the driving member 621 is retracted, the two adjusting members 610 move away from each other. Thus, the process of linear motion of the adjusting member 610 can be stably realized by the telescopic motion of the telescopic rod. In other embodiments, the driving device 620 further comprises a power device 622 in transmission connection with the telescopic rod, and the power device 622 may be arranged corresponding to the aforementioned electric push rod, electric hydraulic push rod, pneumatic push rod, and hydraulic push rod. The embodiment of the present application is not particularly limited to this.

It should be noted that the extending and retracting operations of the driving device 620 can be adjusted by matching the combustion loads of the combustion system 200 and the fan system 400. For example, the extending and retracting actions of the driving device 620 may be adjusted by means of a PLC (Programmable Logic Controller). For another example, the extension and retraction of the drive 620 may be regulated by hydraulic actuation. The adjustment manner of the driving device 620 is related to the selection of the driving device 620, and may be designed according to actual requirements, which is not specifically limited in the embodiment of the present application.

With continued reference to fig. 4, in some embodiments, the wall-hanging stove further includes a connecting member 630, and the driving device 620 is connected to the two adjusting members 610 by means of the connecting member 630. For example, fig. 4 illustrates a case where the connecting members 630 are connecting plates and the adjusting members 610 are adjusting plates, and two connecting members 630 correspond to two adjusting members 610 one by one. The adjusting part 610 is provided with a positioning column 640, the connecting part 630 is provided with a positioning hole 631 corresponding to the positioning column 640, and the connecting part 630 is precisely positioned on the adjusting part 610 by the cooperation of the positioning hole 631 and the positioning column 640. As an embodiment, when the connection member 630 is positioned on the adjustment member 610, the connection member 630 may be fixed to the adjustment member 610 by welding, so that the connection member 630 is integrated with the adjustment member 610. The driving unit 620 is connected to the connection member 630 by a set screw. Thus, the driving device 620 is connected with the adjusting member 610 through the connecting member 630, so that the installation is convenient, and the movement process of the adjusting member 610 pushed by the driving device 620 is more stable.

With continued reference to fig. 2 to 3, in some embodiments, the wall-hanging stove further includes a guide 120 disposed on the wall-hanging stove body 100, and the guide 120 is used for guiding the movement of the two adjusting members 610. Thus, by providing the guide member 120, the movement process of the adjustment member 610 is more stable. Specifically, in some embodiments, the two adjusting members 610 are respectively a first side and a second side along two sides (i.e., the up-down direction shown in fig. 2 and 3) in the moving direction (i.e., the left-right direction shown in fig. 2 and 3), and the guide member 120 is located on the first side and the second side. In one embodiment, the guiding element 120 is a guide rail, and the two adjusting elements 610 are respectively provided with a sliding block adapted to the guide rail. Thus, it can be used to support and guide the adjusting member 610 to reciprocate linearly in a given direction.

It should be noted that, the sliding block may be fixed to the adjusting member 610 through a fixing screw, and the guide rail may also be fixed to the wall-hanging stove body 100 through a fixing screw, so that the process of the driving device 620 pushing the adjusting member 610 to move will be smoother, the occurrence of the conditions of jamming or deadlocking and the like during the moving process is avoided, and finally, the state of completely closing the fluid inlet 111 is realized under the pushing-out action of the driving device 620.

With continued reference to fig. 3, in some embodiments, the profile of the smoke outlet 510 and the profile of the opening 110 are circular, and the profile of the fluid inlet 111 is defined as annular. That is, the contour of the fluid inlet 111 is related to the shape of the smoke exhaust duct 500 and the opening 110, and can be set according to the use requirement, which is not specifically limited in the embodiment of the present application.

The adjustment process of the adjustment assembly 600 in the embodiment of the present application is as follows:

when the hanging stove normally works, combustion system 200 carries out normal burning, and the produced high temperature flue gas of burning passes through main heat exchanger 300 and heats the water in the heating system, and the water of heating flows through the radiator of installing indoor under the water pump drive to give off the heat to indoor through the radiator, reach the purpose of heating. At this time, the flue gas generated in the combustion process is forcibly discharged out of the room through the smoke discharge pipe 500 under the driving of the fan system 400, and the whole wall-hanging furnace body 100 is always in a negative pressure state because the fan system 400 continuously discharges the combusted flue gas out of the room. Outdoor air is forcibly sucked into the wall-mounted furnace body 100 through the fluid inlet 111, the air is distributed again after entering the wall-mounted furnace body 100 and is used for primary injection air and secondary supply air, and the air is used for participating in components required by combustion, so that uninterrupted smoke exhaust and air intake are realized when the interior of the wall-mounted furnace body 100 is in a negative pressure state under the driving of the fan system 400 in the whole process. When the wall-hanging stove is burning under normal load, at this time, the driving member 621 is in a shortened state, the two adjusting members 610 do not shield the fluid inlet 111, the intake air amount reaches a maximum state, and the combustion system 200 reaches an optimal combustion condition. When the user adjusts the temperature of the heating water, the combustion system 200 feeds back the air amount required by the combustion system 200 to the driving device 620 to control the intake air amount in order to match the optimal combustion state, and at this time, the driving device 620 adjusts the intake air amount according to the air intake air amount, and the driving member 621 pushes the two adjusting members 610 to move in the direction to approach each other. In order to balance the intake air into the wall-hanging stove body 100, the intake air is distributed equally on the driving parts 621 on the left and right sides. At this time, the driving members 621 on both sides move synchronously to stop moving after reaching the position of the required air intake, so as to ensure the accurate air intake requirement. Correspondingly, when the wall-hanging stove resumes the maximum load state for combustion, the feedback that the air quantity required by the combustion system 200 is insufficient is transmitted to the driving device 620 to control the air inflow, at this time, the driving device 620 detects that the air inflow needs to be adjusted to the maximum value, the driving piece 621 pushes the two adjusting pieces 610 to move in the direction away from each other until the opening area of the fluid inlet 111 is maximum, the maximum air inflow is reached, so as to realize the maximum air inflow requirement and ensure that the combustion can fully meet the requirement.

To sum up, this application embodiment can adjust the concertina movement of driving piece 621 according to combustion load's state through the adjusting part 600 that sets up in hanging stove body 100 opening 110 department, and then adjusts two regulating part 610 states, realizes the adjustable control of intake. Meanwhile, the implementation of automatic air intake regulation of all wall-mounted furnaces can be general, the wall-mounted furnaces with variable-frequency fans can be directly omitted, the rotating speed is regulated appropriately according to wall-mounted furnace products with different combustion loads, the requirement of the air intake is met, the same balance state is achieved, and the problem that the product cost is increased due to the variable-frequency fans is avoided. In addition, this application embodiment can realize the accurate control of intake, and when burning load changed, drive arrangement 620 can receive real-time feedback information and control the state of adjusting part 610, can automatically regulated intake rapidly, has ensured that the hanging stove is in the operation of stable equilibrium state. The embodiment of the application has the advantages of simple structure, easiness in implementation, capability of saving the internal space and reduction of hardware cost.
