TECHNICAL FIELD OF THE INVENTION
The present invention relates to an air conditioner, and for example, relates to a commercial large-scale air purifier having an air purifying function.
[0002]
[Prior art]
2. Description of the Related Art An air conditioner is known as a device for controlling the temperature, humidity, and pollution degree of indoor air. In these air conditioners, indoor air is taken into the device, the physical properties of the taken air are changed to air in a desired state, and then the air is blown out of the device. In particular, with recent changes in the living environment, an air conditioner having an air purifying function for improving the degree of indoor air pollution has attracted attention. Conventionally, air purifiers having a dust collecting function and a deodorizing function have been widely used.However, in addition to these functions, air purifiers having a function of controlling or eliminating bacteria harmful to the human body have been developed. In recent years, it has become popular. Here, "bacteriostatic" refers to killing most of the bacteria attached to the fibrous filter and reducing the absolute number thereof. Further, "bacterial elimination" refers to removing airborne bacteria floating in the air and reducing the absolute number of airborne bacteria in the air.
[0003]
In such an air purifier, the dust collecting function, the deodorizing function, and the bacteriostatic function are exerted by various filters installed in the ventilation path. Further, the sterilization function is exhibited by installing an ion generator for generating positive ions and negative ions in an air passage (for example, see Patent Document 2). When the concentration of negative ions in the air is increased by using this ion generator, a relaxation effect can be obtained.
[0004]
In such an air conditioner having an air purifying function, it is necessary to determine the output of the blower according to the size of the room in which the air conditioner is installed. In a home air conditioner used in a room having a relatively narrow space such as a general home, even a relatively low-output blower can convect air to every corner of the room, A sufficient air cleaning effect can be obtained. However, in commercial air conditioners mainly used in rooms having a large space such as restaurants, offices, hospitals, etc., blowers having an extremely high output are used to convect air to every corner of the room. Need to be used.
[0005]
As commercial large-scale air conditioners, there are a built-in type that is integrated into a building, and an installation type that can be installed freely without being incorporated into a building. Among these, the air conditioners of the installation type include a floor-standing type installed on the floor and a wall-mounted type installed on the wall. 2. Description of the Related Art Conventionally, wall-mounted air conditioners are generally used as commercial air conditioners.
[0006]
FIG. 12 shows a schematic vertical sectional view of a floor-standing type commercial air cleaner provided with a high-output blower. As shown in FIG. 12, the main body of the air purifier has a box-shaped casing 101. A front panel 107 is attached to a front surface of the casing 101. An operation unit 120 for switching the operation state is provided in front of the upper surface of the casing 101. In addition, a base leg 116 for installation on the floor is provided on the lower surface of the casing 101.
[0007]
On the front surface of the casing 101 behind the front panel 107, a suction port 102 for taking air into the casing 101 is provided. An outlet 103 for blowing air is provided on the upper surface of the casing 101. Inside the casing 101, an air passage 104 extending from the suction port 102 to the air outlet 103 is formed.
[0008]
A filter 112 is disposed in the ventilation passage 104 behind the air inlet 102. The filter 112 includes a pre-filter 108 for removing large dust such as cotton dust, a deodorizing filter 109 having a deodorizing function, a bacteriostatic filter 110 having a bacteriostatic function, and a dust collecting filter 111 for capturing fine particles having a small particle diameter. Consists of On the downstream side of the filter 112, a blower fan 106 driven to rotate by a drive motor 105 is arranged.
[0009]
In the air purifier having the above configuration, the air is taken into the casing 101 from the suction port 102 by the rotation of the blower fan 106. The air taken into the casing 101 passes through the ventilation passage 104, and the filter 112 purifies the air. The air that has entered a desired state by passing through the filter 112 is blown out from the outlet 103 into the room.

[Problems to be solved by the invention]
However, in the commercial air purifier having the above configuration, a large noise is generated during operation. This is due to the use of a high-powered blower, the noise of the drive motor itself for operating the blower, the wind noise of the blower cutting off the wind, and the wind noise generated by air flowing through the ventilation path. According to. Usually, as the output of the blower increases, these noises also tend to increase in proportion. Although it is possible to suppress noise by increasing the size of the device body, there is a problem in that the installation space is increased.
[0013]
Therefore, an object of the present invention is to solve the above-described problems, and an object of the present invention is to provide an air conditioner that can suppress an increase in noise due to an increase in airflow output.
[0014]
[Means for Solving the Problems]
An air conditioner according to the present invention includes a ventilation path, a filter, and a blowing unit. The ventilation path has a plurality of paths which are communicated between an inlet and an outlet provided on the surface of the device main body and are partitioned in parallel. The filter is disposed in the ventilation passage and purifies the passing air. The blowing means is arranged on each of the plurality of paths divided in parallel. As described above, by using a plurality of low-output blowing means to obtain a desired blowing capacity instead of using a high-output blowing means, the output required for one blowing means can be reduced. In addition, it is possible to reduce the noise generated by the operation of the blower. In addition, by providing a configuration in which the ventilation paths are divided in parallel corresponding to the respective air blowing means, disruption of the air flow hardly occurs, and generation of turbulence is largely suppressed. For this reason, generation of noise due to turbulence in the airflow is also suppressed. As a result, an effect is obtained in which noise is significantly reduced as compared with a case where a high-output air blowing means is used to obtain a desired air blowing capacity.
[0015]
In the air conditioner according to the present invention, for example, it is preferable that the plurality of blowing units are arranged downstream of the filter, and that the distances from the respective blowing units to the filter are different from each other. . In this way, by configuring the distance from each of the blowers to the filter to be different from each other, it becomes possible to change the intake efficiency of each blower. This is because the pressure loss of the air passing through the ventilation path changes by changing the distance from the filter to the blower. As a result, various operation modes can be realized by controlling the outputs of the plurality of blowing means.
[0016]
In the air conditioner according to the present invention, for example, the filters are divided corresponding to a plurality of paths, and the thickness of each filter is different depending on the distance to each blowing means. preferable. In this way, the filter is divided in accordance with each path of the ventilation path and the ventilation means installed therein, and the divided filter is set to have a thickness corresponding to the distance to the ventilation means, so that the ventilation capacity can be freely adjusted. It becomes possible to design. For example, in the case of having the same capacity of the blowing means, by making the filter corresponding to the blowing means arranged at the rear moderately thicker than the filter corresponding to the blowing means arranged at the front, the blowing capacity in both paths is improved. Can be equivalent.
[0017]
In the air conditioner according to the present invention described above, for example, the device main body has a vertically long shape, a suction port is disposed on the front surface of the device main body, and an air outlet is disposed on the upper surface of the device main body. A ventilation path communicating with the outlet includes a first path communicating between a first suction port disposed above a front surface of the device main body and a first outlet disposed in front of the upper surface of the device main body, and a front surface of the device main body. It is preferable that the second suction port is divided in parallel into a second path communicating between a second suction port arranged below and a second air outlet arranged rearward on the upper surface of the device main body. As described above, in the air conditioner including the device main body having a vertically long shape, by configuring a plurality of paths divided in parallel as described above, the device configuration is simplified and the air cleaning effect is improved. Are simultaneously satisfied.
[0018]
In the air conditioner according to the present invention, for example, it is preferable that a sound absorbing material is attached to an inner wall surface of a wall constituting the ventilation path. Further, in the air conditioner according to the present invention, for example, the wall forming the ventilation path has a plurality of through holes, and the outer wall surface of the wall forming the ventilation path covers the plurality of through holes. It is preferable that a sound absorbing material is attached. As described above, by attaching the sound absorbing material to the ventilation path, noise generated in the ventilation path is absorbed by the sound absorbing material, so that noise leaking to the outside of the device is further reduced. For this reason, the noise can be further reduced.
[0019]
In the air conditioner according to the present invention, for example, it is preferable that the upper surface of the device main body has a shape that prevents placement of articles. In this way, by making the upper surface of the device main body into a shape in which articles cannot be placed, the possibility that articles fall from the air outlet into the device main body is reduced, so that an air conditioner that is hard to break down can be provided. Will be possible.
[0020]
In the air conditioner according to the present invention, for example, it is preferable that the upper surface of the device main body is continuously inclined in a direction of decreasing the height rearward. As the shape of the upper surface of the device main body for preventing the placement of articles as described above, for example, a shape having only a slope as in this configuration can be considered.
[0021]
In the air conditioner according to the present invention, for example, the filter preferably has at least one of a dust collecting function, a deodorizing function, and a bacteriostatic function. By providing the filter with any of the functions described above, air can be cleaned.
[0022]
In the air conditioner according to the present invention, for example, an ion generator that is located downstream of the filter and the blowing means in the ventilation path and sends out at least one of positive ions or negative ions into the air. Preferably, it is equipped with a device. As described above, by disposing the ion generator in the ventilation path, it is possible to obtain a sterilization effect and a relaxation effect.
[0023]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Note that, in the present embodiment, a description will be given of a large-scale air purifier for business use assuming that the air conditioner is used in a room having a relatively large space.
[0024]
FIG. 1 is a perspective view of an air purifier according to an embodiment of the present invention, and FIG. 2 is a schematic longitudinal sectional view taken along line II-II of the air purifier shown in FIG. As shown in the figure, the air purifier in the present embodiment is a floor-standing type air purifier having a vertically long shape.
[0025]
(Overall structure)
As shown in FIGS. 1 and 2, the device body of the air purifier in the present embodiment has a vertically long box-shaped casing 1. A front panel 7 is attached to a front surface of the casing 1. A suction port 2 for taking in air into the casing 1 is provided on a front surface of the casing 1 located behind the front panel 7. On the upper surface of the casing 1, an outlet 3 for blowing out the air inside the casing 1 to the outside is provided. Inside the casing 1, an air passage 4 communicating between the inlet 2 and the outlet 3 is provided.
[0026]
An operation unit 20 for switching the operation state is disposed in front of the upper surface of the casing 1. On the lower surface of the casing 1, there are provided base legs 16a and 16b for installing the air cleaner on the floor surface. Among the base legs 16a and 16b, the base leg 16a positioned forward has a configuration in which the height can be adjusted in order to enhance stability during installation. The bottom surfaces of the base legs 16a and 16b are made of rubber to prevent the vibration of the air purifier from propagating to the floor.
[0027]
A caster 17 is attached to the rearmost portion of the lower surface of the casing 1. A handle 29 is provided on the back of the casing 1. The casters 17 and the handles 29 are provided to facilitate the movement of the device main body, and the device main body can be easily moved by holding the handle 29 and tilting the casing 1 rearward during the movement. Becomes possible.
[0028]
A filter 12 is arranged behind the suction port 2. The filter 12 is divided into upper and lower parts to facilitate maintenance work, and is fitted in the filter frame 13 and installed in the ventilation path 4. Each of the filters 12a and 12b is arranged in this order from the upstream in the order of the pre-filters 8a and 8b, the deodorizing filters 9a and 9b, the bacteriostatic filters 10a and 10b, and the dust collecting filters 11a and 11b.
[0029]
The pre-filters 8a and 8b are filters formed by plain weaving a thin metal wire, and capture relatively large dust such as cotton dust. By arranging the metal pre-filters 8a and 8b at the forefront in this way, even if a cigarette fire falls from between the casing 1 and the front panel 7 toward the suction port 2, the entire filter 12 is covered. It is prevented from spreading and becomes excellent in safety.
[0030]
The deodorizing filters 9a and 9b are filters containing a substance having a deodorizing function such as activated carbon, and exhibit a deodorizing function by adsorbing odor components. The bacteriostatic filters 10a and 10b have a function of suppressing the growth of bacteria attached to the filters and reducing the number thereof. As the dust collection filters 11a and 11b, HEPA (High Efficiency Particulate Air) filters are used to capture fine particles having a small particle diameter contained in the air.
[0031]
An angle 21 is disposed downstream of the filter 12, a first suction port 2 a is provided at an upper portion of the angle 21, and a second suction port 2 b is provided at a lower portion of the angle. The first suction port 2a and the second suction port 2b are respectively covered by a fan guard (not shown). The ventilation passage 4 downstream of the position where the first and second intake ports 2a and 2b are provided is partitioned by a partition. Thereby, the ventilation path 4 is divided into a first path 4a and a second path 4b.
[0032]
A first drive motor 5a is disposed downstream of the first suction port 2a, and a first blower fan 6a as a blower is attached to a rotating shaft of the first drive motor 5a. A second drive motor 5b is disposed downstream of the second suction port 2b, and a second blower fan 6b as a blower is attached to a rotation shaft of the second drive motor 5b. As the first and second blower fans 6a and 6b, for example, sirocco fans capable of blowing air entering from the direction of the rotation axis in a direction intersecting with the rotation axis are used. Since this sirocco fan has relatively low wind noise, it is suitable for suppressing noise.
[0033]
The first path 4a and the second path 4b merge downstream of the first and second blowing fans 6a, 6b, and communicate with the outlet 3 provided on the upper surface of the casing 1. A movable louver 15 for adjusting the direction of the blown air is disposed at the outlet 3. The movable louver 15 is for changing the wind direction freely in the front, rear, left and right directions. The outlet 3a of the first path 4a is located on the front side of the upper surface of the casing 1, and the outlet 3b of the second path 4b is located on the rear side of the upper surface of the casing 1.
[0034]
An ion generator 14 is disposed downstream of the blower fan 6b in the second path 4b. The ion generator 14 is a device that generates positive ions and negative ions. For example, the ion generator 14 generates approximately 50,000 to 150,000 positive and negative ions per cubic centimeter, thereby removing floating bacteria floating in indoor air. Exhibits the air purifying function to remove bacteria. Also, by generating only negative ions, a relaxation effect is expected to be obtained.
[0035]
The blower fan 6a arranged in the first path 4a and the blower fan 6b arranged in the second path 4b are arranged so that the distances from the filter 12 located in front of the fan 6a are different from each other. In the air purifier according to the present embodiment, the second blower fan 6a is disposed so as to be located behind the first blower fan 6b.
[0036]
(Action / Effect)
As in the above configuration, when designing a large-scale air purifier for business use, a desired output can be obtained by combining two low-output blowers instead of using a high-output blower as a blower. With such a configuration, it is possible to suppress generation of noise. That is, by using two low-output blowers instead of using one high-output blower fan to obtain the same air volume, it is possible to further reduce noise generated by the blower fans themselves. .
[0037]
In this case, by dividing the ventilation path into two paths in parallel and arranging the blower fans in the respective paths, it becomes difficult for airflow to be disrupted in the ventilation path, and turbulence is prevented from occurring. Become. For this reason, an increase in pressure loss is prevented, and it becomes possible to circulate indoor air with high efficiency even when the output of the blower fan is low. Further, by dividing the ventilation path into a plurality of paths in parallel, the airflow is prevented from being disturbed, so that an increase in wind noise can be suppressed, and as a result, noise can be reduced.
[0038]
Further, by arranging the two blower fans at different distances from the filter as in the above configuration, it is possible to suppress noise during low output operation. This is because the air intake efficiency is improved by arranging the blower fan farther from the filter, and the output of the blower fan is lower when the blower fan is arranged farther to secure a desired air volume. In this way, by disposing one blower fan at the rear and using the blower fan disposed at the rear as a main fan, it is possible to suppress the generation of noise even at the time of low output operation, Various operation modes can be realized.
[0039]
In the above configuration, it is preferable to reduce the manufacturing cost by sharing components. The components that can be shared include mainly a drive motor and a blower fan. However, when the first and second blowers are used as common components, noise of a frequency proportional to the rotation speed called nZ sound increases, so that the first and second blowers are driven at the same rotation speed. It is preferable to control the rotation so that the rotation is performed with a difference in the number of rotations instead of the rotation. Further, in order to prevent resonance due to the use of fans having the same shape, it is preferable that the pitch of the blades provided in the blower fan is not a fixed pitch but a random pitch.
[0040]
Further, as described above, when a difference is made between the rotation speeds of the two blower fans, the distance from the filter to the blower fan is defined as the distance based on the air flow difference generated according to the difference between the rotation speeds. Is preferred. The distance based on the air flow difference refers to a distance at which the pressure loss until reaching the fan after passing through the filter becomes the same in the first and second paths. As described above, by setting the distance based on the difference in the amount of air, there is no difference in the amount of air between the first and second paths, so that it is possible to send air with good balance between the two paths.
[0041]
Note that a DC motor is preferably used as the drive motor. This is because the DC motor consumes less power than the AC motor, and the increase in power consumption due to the use of two drive motors is kept as low as possible. Further, if a DC motor is employed, feedback control can be easily performed by a control means such as a microcomputer, so that air can be circulated with high efficiency. Further, when an AC motor is used, it is preferable to use the same motor in order to share components, but it is preferable to perform triac control in order to prevent a bad effect due to the same number of rotations. .
[0042]
Hereinafter, more preferable operation control and structure of the air cleaner having the above-described configuration will be described in detail for each part with reference to the drawings.
[0043]
(Cleaning operation)
3 and 4 are schematic longitudinal sectional views of the air cleaner according to the present embodiment, showing a state when a cleaning operation is performed. Here, the cleaning operation is an operation mode in which sterilization of the inside of the casing 1 is performed. By performing this cleaning operation periodically, an operation mode in which the inside of the casing 1 can be kept more clean. That is.
[0044]
As shown in FIG. 3, when performing the cleaning operation, first, the movable louver 15 installed in the outlet 3 is rotated to bring the outlet 3 into a closed state. Next, only the second blower fan 6b is turned on, and the first blower fan 6a is turned off. As a result, as shown in FIG. 3, the air taken in from the suction port 2b becomes air containing a large amount of positive ions and negative ions by the ion generator 14 when passing through the second path 4b. Although this air is discharged upward from the second outlet 3b, since the outlet 3 is closed by the louver 15, it enters into the first path 4a from the first outlet 3a. The air that has passed through the first path 4a is blown out from the first suction port 2a toward the filter 12a, but is sucked into the second suction port 2b again by the second blower fan 6b. As a result, as shown in the figure, air containing a large amount of positive ions and negative ions circulates in the ventilation path 4. This operation state is continued for a predetermined time.
[0045]
By performing the operation mode as described above, air containing a large amount of positive ions and negative ions circulates in the first path and the second path inside the casing, and the sterilization effect inside the casing is obtained. Will be able to By periodically performing the cleaning operation, the inside of the casing can be kept clean at all times, and the frequency of performing full-scale cleaning work can be reduced.
[0046]
In the cleaning operation, as shown in FIG. 4, the first blower fan 6a may be turned on and the second blower fan 6b may be turned off. Also in this case, as shown in the drawing, air containing a large amount of positive ions and negative ions circulates in the ventilation path 4.
[0047]
(Structure on top of casing)
FIG. 5 is a side view of the upper part of the casing of the air purifier in the present embodiment. 6 and 7 are side views showing other preferable shapes of the upper portion of the casing.
[0048]
As shown in FIG. 5, the upper surface of casing 1 in the present embodiment has a front area located forward of outlet 3 and a rear area where outlet 3 is formed. In the front region, the upper surface of the casing 1 has a curved surface that is continuously inclined in a direction of decreasing the height rearward. In the rear region, the upper surface of the casing 1 has an inclined surface that is continuously inclined in a direction of decreasing the height toward the rear.
[0049]
By forming the casing upper surface in such a shape, a user is prevented from placing an article on the casing upper surface. When an article is placed on the upper surface of the casing, there is a possibility that the object may fall from the outlet into the ventilation path inside the casing due to some impact or vibration. In the event that the device falls, it may cause a failure of the device. Therefore, in this embodiment, the user is prevented from placing an article on the upper surface of the casing by adopting the above shape. Examples of the article include a small article or a cup containing a drink that the user may intentionally place.
[0050]
The shape of the upper surface of the casing that prevents the user from placing an article on the upper surface of the casing may be the shape shown in FIG. 6 or the shape shown in FIG. The shape shown in FIG. 6 is a case where a curved surface shape continuously inclined in a direction of decreasing the height rearward is adopted over the entire upper surface of the casing 1. The shape shown in FIG. 7 is a case where an inclined surface continuously inclined in the direction of decreasing the height rearward is formed over the entire upper surface of the casing 1.
[0051]
(Sound absorbing material mounting structure)
FIG. 8 is a cross-sectional view illustrating a structure of a ventilation path of the air purifier according to the present embodiment. FIG. 9 is a sectional view showing the structure of another preferred ventilation path.
[0052]
As shown in FIG. 8, a sound absorbing material 19 is affixed to the inside of a wall 18 constituting a ventilation path of the air purifier in the present embodiment. As the sound absorbing material 19, for example, a soft urethane foam is used. The sound-absorbing material 19 is for preventing wind noise generated by blowing air onto the wall surface and noise generated by the blower fan or the drive motor from leaking to the outside, and is stuck inside the wall 18 constituting the ventilation path. This effectively suppresses noise leakage to the outside. In the air purifier according to the present embodiment, the air passage to which the sound absorbing material 19 is attached is not limited to the first path 4a and the second path 4b, but also from the suction port 2 to the first and second suction ports 2a and 2b. A ventilation path leading to the air outlet or a ventilation path extending from the first and second air outlets 3a and 3b to the air outlet 3 may be considered. Also, the noise can be prevented from leaking to the outside by being attached to the inner wall surface of the casing 1.
[0053]
As shown in FIG. 9, a large number of through holes 18a are provided in a wall 18 forming a ventilation path, and a sound absorbing material 19 is attached to the outside of the wall 18 forming a ventilation path so as to cover the through hole 18a. Is also good. Also in this case, the noise is effectively prevented from leaking to the outside.
[0054]
(Front panel mounting structure)
FIG. 10 is an enlarged sectional view showing a mounting structure of a front panel of the air purifier according to the embodiment of the present invention. FIG. 10A shows a state before mounting, and FIG. 10B shows a state after mounting.
[0055]
As shown in FIG. 10A, a locking portion 24 is provided protruding near the upper end of the rear surface of the front panel 7. The locking portion 24 has a through hole penetrating in the up-down direction. At a predetermined position on the front surface of the casing 1, a lock receiving portion 25 is provided so as to protrude corresponding to the lock portion 24. The lock receiving portion 25 has a nut 32 embedded therein, and a through hole is formed concentrically with the hole of the nut. The locking portion 24 and the locking receiving portion 25 are configured such that a gap of a predetermined distance is formed in the vertical direction in a state where the front panel 7 is attached to the casing 1.
[0056]
The bolt 31 is inserted into the through hole provided in the locking portion 24 from above through a spring 33. The spring 33 urges the screw head of the bolt 31 upward. Further, an E-ring 31 a is fitted into a predetermined position of the bolt 31, and is attached so that the bolt 31 does not fall off the front panel 7. The screw head of the bolt 31 is located at a position protruding from the upper end of the front panel 7 when not fastened.
[0057]
When attaching the front panel 7 to the casing 1, first, the lower end of the front panel (not shown) is inserted into a receiving portion provided below the front surface of the casing. Subsequently, the front panel 7 and the casing 1 are set so as to be parallel, and the bolt 31 is pressed down against the spring 33. Next, the bolt 31 is rotated while the bolt 31 is pressed down, and fastened to the nut 32 provided on the locking receiving portion 25. As described above, the front panel 7 is fixed to the casing 1 as shown in FIG.
[0058]
With the front panel mounting structure having the above configuration, the front panel can be easily mounted on the casing. Further, since the bolt does not fall off the front panel, the bolt is not lost when the front panel is removed. Further, since the screw head of the bolt is pushed up to a position protruding from the upper end of the front panel by the spring when the bolt is not fastened, it is easy to confirm whether the bolt is securely fixed.
[0059]
(Composition of ventilation path)
FIG. 11 is a schematic vertical sectional view showing another modification of the air purifier in the present embodiment. Specifically, the configuration of the ventilation path is different from that of the above embodiment. As shown in FIG. 11, in the present modification, a partition wall 4c is provided between the two angles 21 and the filter 12, and the ventilation path 4 is provided on the downstream side of the filter 12 by the partition wall 4c. And the second path 4b.
[0060]
With this configuration, since the space from the filter to the angle is divided by the partition into the first path and the second path, the cross-sectional area of the ventilation path is reduced, and the occurrence of turbulence is more reliably prevented. Become like As a result, the generation of noise is further suppressed.
[0061]
In the above embodiment, the case where the ventilation path is divided into two paths in parallel and two ventilation units are provided has been described as an example. However, the invention is not particularly limited to this. And the number is not limited.
[0062]
Further, in the above-described embodiment, the case where the vertically divided filters have the same thickness has been described as an example, but the thickness may be changed vertically. By changing the thicknesses of the upper and lower filters in this manner, it is possible to freely design the blowing capacity.
[0063]
Further, in the above embodiment, an air purifier was described as an example of an air conditioner. However, the present invention is not limited to an air purifier, but may be a dehumidifier, a humidifier, a cooling device, a heating device, or any of these.
