Definitions
- the present invention relates to a device for heating a liquid and/or for heating air. Furthermore, the invention relates to a side channel blower.
- the side outlet of the air means that a side channel has to be routed around the fan wheel. This is a structural challenge and reduces the available space.
- An object of the invention is to propose an air conveying device which is characterized by a reduced requirement in relation to the connection with other components.
- the air conveying device is preferably provided for a device for heating a liquid or for heating air.
- a device for heating a liquid and/or for heating air with a burner device and an air conveying device, the burner device generating thermal energy by burning a fuel-air mixture in a combustion chamber, the Air conveying device conveys combustion air to the burner device, the air conveying device being a
- the carrier housing has a movable fan wheel, an air inlet and an air outlet, the carrier housing having a conveying duct which is connected to the air inlet and the air outlet, the fan wheel being arranged such that it can rotate about a longitudinal axis of the air conveying device and having a blade structure, the air outlet in is arranged in a central area of the air conveying device, and wherein the air outlet extends through the fan wheel.
- the air outlet and/or the air inlet serve to ensure that not only air but also a fuel-air mixture exits or enters.
- the longitudinal axis, around which the fan wheel rotates, runs through the middle region of the air conveying device.
- the air or the fuel-air mixture is conveyed through the conveying channel and the blade structure from the air inlet to the air outlet and is preferably compressed in the process.
- the air outlet is located in the central area of the air conveying device and not on the side as in the prior art.
- the middle area and side or lateral area are understood here in the radial direction, starting from the longitudinal axis. The location of the air exit eliminates the prior art need for a duct around the fan wheel leading to the burner assembly.
- the burner device and, for example, also the combustion chamber
- the burner device to be arranged axially along the longitudinal axis of the air conveying device behind the air conveying device, resulting in an arrangement that is slim in circumference.
- One advantage of the fuel/air mixture exiting in the middle is that this leads to a uniform flow to the downstream burner device.
- this can simplify the configuration of the combustion device. Since the air outlet extends through the fan wheel, the fan wheel has the air outlet located in the center of the air conveying device and therefore also in the center of the fan wheel.
- the air outlet includes a bearing component of the fan wheel, via which the fan wheel is rotatably arranged in the air conveying device.
- the air conveying device is designed as a side channel fan.
- Side channel blowers or side channel blowers are stationary well known in the art. In these, however, there is - in contrast to the invention - an outlet for the air or the fuel-air mixture on the side.
- the air inlet is arranged on a lateral area of the air conveying device.
- the air thus enters the conveying channel from the side—again radially around the circumference of the longitudinal axis—and leaves it in the middle area.
- An embodiment of the device includes that the air outlet extends through the carrier housing.
- the carrier housing has the air outlet, which is located in the center of the air conveying device and thus also in the center of the carrier housing.
- both the air inlet and the air outlet are located in the carrier housing.
- the impeller is attached to the engine such that the opening of the side of the impeller that has the blade structure faces away from the engine.
- the invention solves the problem with a side channel blower with a support housing, a movable fan wheel, an air inlet and an air outlet, the support housing having a conveying channel which is connected to the air inlet and the air outlet, the fan wheel being arranged such that it can rotate about a longitudinal axis of the air conveying device and has a blade structure, wherein the air inlet is arranged at a lateral area of the air conveying device, wherein the air outlet is arranged in a middle area of the air conveying device, and wherein the air outlet extends through the fan wheel.
- One configuration of the side channel fan is that the air outlet extends through the support housing.
- FIG. 3 shows the air conveying device of FIG. 2 in an exploded view
- Fig. 4 view of the outside of the fan wheel of Fig. 2,
- FIG. 5 view of the inside of the fan wheel of Fig. 2,
- Fig. 6 shows the exploded view of Fig. 3 from the opposite viewing direction
- Fig. 7 a view of the carrier housing 20.
- FIG. 1 For the sake of clarity, only the part consisting of the burner device and the air conveying device is shown in FIG. 1 of the device for heating a liquid and/or for heating air.
- the burner device 1 has a combustion chamber 10 in which a fuel-air mixture is burned. The thermal energy released in the process is transferred to the liquid or air via a heat exchanger (not shown here).
- the air is preferably the room air in a caravan or mobile home.
- the so-called combustion air required for the combustion is introduced into the combustion chamber 10 by the air conveying device 2 .
- the air conveying device 2 conveys only the combustion air or already the fuel-air mixture into the combustion chamber 10.
- the air conveying device 2 is located axially in front of the burner device 1 and thus also in front of the combustion chamber 10.
- FIGS. 2 and 3 . 4 shows the outside of the fan wheel 21. The three illustrations are described together.
- the air conveying device 2 is designed in the manner of a side channel compressor.
- a fan wheel 21 is arranged so that it can rotate about the longitudinal axis 25 , with the rotation being effected by the motor 29 .
- An axis of rotation of the motor 29 extends through the carrier housing 20 and through a middle region 27 of the fan wheel 21 .
- the air to be conveyed through the air conveying device 2 (possibly as part of a fuel-air mixture) passes through the air inlet
- the air inlet 22 is in the lateral area 28 and that the air outlet 23 is in the central area 27 of the air conveying device 2 .
- the air outlet 23 is located in the center of the fan wheel 21 and, in addition, a support structure, via which the fan wheel 21 is fastened in the air conveying device 2 and the motor 29 transmits the torque to the fan wheel 21 .
- there are five further blade elements in the air outlet 23 . The number of these blade elements is not limited to five, they can also be more or fewer in number.
- FIG. 5 shows the blade structure 26 of the fan wheel 21 , through which the air or the fuel-air mixture is compressed and moved to the central air outlet 23 .
- the inside of the fan wheel 21 with the blade structure 26 can also be seen in the illustration in FIG. 6 .
- the motor 29 protrudes clearly with an axis of rotation along the longitudinal axis 25 of the air conveying device 2 through the support housing 20 with the lateral air inlet 22 and through the fan wheel 21 with the central air outlet 23.
- FIG. 7 shows a view of the inside of the carrier housing 20.
- the conveying channel 24 can be seen, which extends from the air inlet 22 on the side 28 to the center 27 of the carrier housing 20 and opens out there.
- the air or the fuel-air mixture is compressed by the blade structure of the fan wheel and its rotation.
- Blade structure middle area lateral area
