Description

The present invention relates to a fan convector.

A fan convector is known in which a heat exchanger through which hot water circulates and a fan that circulates indoor air are housed within a casing. In general, a fan convector is configured such that, when the fan is operated, indoor air is drawn into the casing through an intake port provided on the rear side of the casing, the indoor air is heated by the heat exchanger, and the warm air is blown out from an outlet provided on the front side of the casing (for example, Patent Document 1).

JP 2001-263697 A

However, a fan convector with an intake port on the rear side of the casing as described above needs to be installed a certain distance away from the wall of the room so that the intake port is not blocked. However, depending on the installation environment of the fan convector, the rear side of the fan convector may be attached to the wall of the room. In such an installation environment, there is a problem that stable heating performance is difficult to obtain because sufficient indoor air is not sucked into the casing through the intake port on the rear side even when the fan is operated.

The present invention was made to solve the above problems, and the object of the present invention is to provide a highly versatile fan convector that is not limited by the installation environment.

According to a first aspect of the present invention,
A casing;
a heat exchanger that heats indoor air drawn into the casing from the room by a circulating heat medium;
A fan convector including: a fan that draws indoor air from inside the room into a casing and blows out warm air into the room;
A blowing section for blowing hot air from inside the casing into the room is provided on a part of the front side of the casing,
A fan convector is provided in which the casing is configured so that the arrangement of an intake section that draws indoor air into the casing and a blocking section that blocks the intake of indoor air into the casing can be switched between the front side and the rear side.

According to the above fan convector, the casing is provided with a suction section for sucking indoor air into the casing and a blocking section for blocking the intake of indoor air into the casing that can be switched between the front side and the rear side, so that the location of the suction section can be changed according to the installation environment of the fan convector. Also, according to the above fan convector, indoor air is not sucked into the casing from the side where the blocking section is provided, but is sucked into the casing only from the side where the suction section is provided, so that the indoor air sucked from the suction section can flow smoothly into the casing along the air passage formed by the operation of the fan. This allows the fan convector to exhibit a predetermined heating performance regardless of the installation environment, and allows the fan convector to exhibit a predetermined heating performance whether the rear side of the casing is attached to the wall surface of the room or is a certain distance away from the wall surface of the room.

According to a second aspect of the present invention,
a casing having a casing body and an outer plate detachably attached to the casing body;
A fan convector that houses a heat exchanger in a casing body, the heat exchanger heating indoor air drawn into the casing from inside the room by a circulating heat medium, and a fan drawing indoor air from inside the room into the casing and blowing out warm air into the room,
A blowing section for blowing hot air from inside the casing into the room is provided on a part of the front side of the casing,
A fan convector is provided in which at least two of the four sides of the casing (front, back, left and right) are configured so that the arrangement of the suction section that draws indoor air into the casing and the blocking section that blocks the suction of indoor air into the casing can be switched between one side and the other side by switching the attachment direction of the outer plate to the casing body.

According to the above fan convector, the arrangement of the suction section and the cutoff section can be switched with a simple configuration.

According to a third aspect of the present invention,
A casing;
a heat exchanger that heats indoor air drawn into the casing from the room by a circulating heat medium;
A fan convector including: a fan that draws indoor air from inside the room into a casing and blows out warm air into the room;
A blowing section for blowing hot air from inside the casing into the room is provided on a part of the front side of the casing,
At least two of the four side surfaces of the casing, i.e., the front, rear, left and right, are provided so that the arrangement of the suction section that draws the room air into the casing and the blocking section that blocks the suction of the room air into the casing can be switched between one side surface and the other side surface,
Regardless of whether the suction portion is disposed on the one side surface side or the other side surface side, a bypass passage is provided that has a one side surface side bypass passage and an other side surface side bypass passage through which indoor air is drawn into the casing from the side surface side on which the suction portion is provided, and a junction portion where both bypass passages join together downstream of the one side surface side bypass passage and the other side surface side bypass passage,
The indoor air flowing into the bypass passage is configured to flow toward the fan without passing through the heat exchanger,
At the junction, a fan convector is provided in which a temperature sensor is disposed.

A fan convector that performs a specific operation according to the temperature of the indoor air is provided with a temperature sensor that detects the temperature of the indoor air before it is heated by the heat exchanger. For this reason, in a fan convector in which the arrangement of the suction section and the cutoff section is switchable, the position of the suction section changes, so it is necessary to provide a temperature sensor on each of the one side and the other side.

However, with the above fan convector, whether the suction portion is located on the one side surface side or the other side surface side, indoor air flows into the one side surface side bypass passage or the other side surface side bypass passage from the side surface on which the suction portion is located. The bypass passage has a junction where the one side surface side bypass passage and the other side surface side bypass passage join downstream of each other, and indoor air flowing into the junction flows toward the fan without passing through the heat exchanger. Therefore, whether the suction portion is located on the one side surface side or the other side surface side, the temperature of the indoor air drawn into the casing can be detected by a single temperature sensor located at the junction.

Preferably, in the fan convector of the second or third aspect,
The arrangement of the suction section and the blocking section can be switched between the front side and the rear side of the casing.

As described above, the present invention can provide a highly versatile fan convector that is not limited by the installation environment.

FIG. 6 is a schematic side view showing the flow of indoor air by a fan convector according to an embodiment of the present invention, in which (a) shows a state when the fan convector is attached to and installed on a wall surface inside a room, and (b) shows a state when the fan convector is installed away from the wall surface inside the room.

The fan convector according to this embodiment will be specifically described below with reference to the attached drawings. First, the basic configuration of the fan convector when it is installed on a wall surface inside a room will be described.

As shown in FIG. 1, the fan convector 1 has a casing 2 in the shape of a substantially rectangular box. A heat exchanger 100 is housed in the upper part of the casing 2, and a fan 200 is housed in the lower part of the casing 2 (see FIG. 3). Hot water supplied from a heat source unit (not shown) circulates through the heat exchanger 100, and heats the indoor air passing through the heat exchanger 100. The fan 200 is a centrifugal fan driven by a motor (not shown). When the fan 200 is operated, indoor air is sucked into the casing 2 through the suction section 7, and hot air is blown into the room from the blowing section 4 formed on the front side of the casing 2. In this specification, the front side where the blowing section 4 is provided is referred to as the front side, the depth direction when the casing 2 is viewed from the front side is referred to as the front-rear direction, the width direction is referred to as the left-right direction, and the height direction is referred to as the up-down direction.

As shown in FIG. 2, the casing 2 has a casing body 3 and an outer plate 6 that is detachably attached to the casing body 3. The casing body 3 has a lower side panel 31, a left side panel 32 and a right side panel 33 that extend upward from the left and right ends of the lower side panel 31, a front side panel 34 that extends upward from the front end of the lower side panel 31, a rear side panel 35 that extends upward from the rear end of the lower side panel 31, and an upper side panel 36 that connects the upper ends of the left and right side panels 32, 33 and the front and rear side panels 34, 35. An operating unit M is provided on the upper side panel 36.

2 and 3, the lower part of the front side panel 34 is provided with a blowing section 4 consisting of a vent hole facing the fan 200 in the casing body 3. Above the blowing section 4 of the front side panel 34, a substantially rectangular front opening 40 is opened, and the front surface of the heat exchanger 100 in the casing body 3 faces the front opening 40. The front opening 40 is opened in a front recess 37 recessed to a predetermined depth on the inner side in the front-rear direction of the casing body 3 from the lower part of the front side panel 34 where the blowing section 4 is provided, and a filter 41 is disposed in the front opening 40. In addition, as shown in FIG. 4 described later, the rear side panel 35 is formed substantially symmetrically with the front side panel 34 in the front-rear direction, except that the blowing section 4 is not provided. Therefore, a rear opening 42 having substantially the same size and shape as the front opening 40 is opened at a position corresponding to the front opening 40 of the rear side panel 35, and the rear surface of the heat exchanger 100 in the casing body 3 faces the rear opening 42. In addition, at a position corresponding to the front recess 37, a rear recess 38 is formed that is recessed from the lower part of the rear side panel 35 to a predetermined depth inward in the front-rear direction of the casing body 3, and the rear opening 42 is opened in the rear recess 38. A filter 43 is disposed in the rear opening 42.

The front side panel 34 has a front frame portion 34a on the left, right, and upper periphery of the front opening 40. Similarly, the rear side panel 35 has a rear frame portion 35a on the left, right, and upper periphery of the rear opening 42. A front bypass hole 34b for the front bypass passage, which will be described later, opens below the front frame portion 34a. Similarly, a rear bypass hole 35b for the rear bypass passage, which will be described later, opens below the rear frame portion 35a corresponding to the front bypass hole 34b (see FIG. 4).

Although not shown, the heat exchanger 100 in the casing body 3 has multiple fins and a heat transfer tube that passes through the fins and through which hot water supplied from the heat source unit circulates. The heat exchanger 100 is fixed upright at the front-rear center of the upper part of the casing 2 by a fixing member (not shown).

The outer panel 6 has an upper outer panel 60 that covers the upper side panel 36 from above and has an opening 67 through which the operating part M is exposed upward, a first outer panel 61 that extends downward from the front end of the upper outer panel 60, a second outer panel 62 that extends downward from the rear end of the upper outer panel 60, and a lower outer panel 63 that extends a predetermined length rearward from the lower end of the first outer panel 61, and is open on both the left and right sides and downward. The upper outer panel 60 is divided at the center between the front and rear, and although not shown, a hinge part is provided on the underside of the upper outer panel 60 so that the first outer panel 61 and the second outer panel 62 spread out a predetermined angle in the front-to-rear direction.

The first and second outer plate panels 61, 62 have approximately the same size and shape. The first and second outer plate panels 61, 62 are each set to a size that can be accommodated in the front and rear recesses 37, 38 recessed inward in the front and rear direction of the front and rear side panels 34, 35 of the casing body 3 described above. Therefore, when the outer plate 6 is attached to the casing body 3 with the first outer plate panel 61 positioned forward, the front side of the casing 2 is formed by the lower region of the front side panel 34 and the first outer plate panel 61, and the rear side of the casing 2 is formed by the lower region of the rear side panel 35 and the second outer plate panel 62.

As shown in FIG. 2, the first outer plate panel 61 has a substantially rectangular outer opening 65. A filter 66 is disposed in the outer opening 65. When the outer plate 6 is attached to the casing body 3 with the first outer plate panel 61 positioned forward, the outer opening 65 faces the front opening 40 and is formed slightly larger in the left-right direction than the front opening 40 so that the front bypass hole 34b opened in the front frame portion 34a around the front opening 40 is covered from the front.

The second outer panel 62 is composed of a flat shielding plate without an opening. The second outer panel 62 faces the rear opening 42 when the outer panel 6 is attached to the casing body 3 with the first outer panel 61 positioned forward, and is formed slightly larger in the left-right direction than the rear opening 42 so that the rear bypass hole 35b opened in the rear frame portion 35a around the rear opening 42 is covered from the rear. In addition, although not shown, a seal member is arranged on the inner peripheral edge of each of the first and second outer panel 61, 62, which abuts against the front and rear frame portions 34a, 35a on the periphery of the front and rear openings 40, 42 on the outer side of the front and rear bypass holes 34b, 35b when the outer panel 6 is attached to the casing body 3 with the first outer panel 61 positioned forward. Therefore, in the state shown in Figures 1 to 3, the outer opening 65 of the first outer plate panel 61 and the front opening 40 of the front side panel 34 form a suction section 7 on the front side of the casing 2 that draws indoor air into the casing 2. Also, the second outer plate panel 62 forms a blocking section 8 on the rear side of the casing 2 that blocks the indoor air from being drawn into the casing 2. Also, the front side and rear side correspond to one side and the other side.

The lower outer panel 63 has a width in the left-right direction that is approximately the same as the opening width of the front opening 40. Also, as shown in FIG. 3, the lower outer panel 63 has a length in the front-rear direction such that when the outer panel 6 is attached to the casing body 3 with the first outer panel 61 positioned forward, the tip portion inserted from the lower end of the front opening 40 into the casing body 3 abuts the lower end of the heat exchanger 100 from below. As a result, when the outer panel 6 is attached to the casing body 3 with the first outer panel 61 positioned forward, the space in front of the heat exchanger 100 in the casing body 3 is blocked by the lower outer panel 63 from the lower space in the casing 2 in which the fan 200 is housed. Therefore, the indoor air sucked into the casing 2 from the front side of the casing 2 is prevented from short-circuiting and circulating toward the fan 200 below without passing through the heat exchanger 100 by the lower outer panel 63. Therefore, in this embodiment, the lower outer panel 63 of the outer panel 6 functions as a short-circuit prevention part.

A scroll-shaped fan casing is provided inside the casing body 3, surrounding the fan 200. The fan casing has an upper fan casing 71 that extends rearward from the inner surface of the front side panel 34 above the blowing section 4 to the center in the front-rear direction above the fan 200, below the lower end of the heat exchanger 100, and a lower fan casing 72 that extends rearward from the inner surface of the front side panel 34 below the blowing section 4 so as to surround the lower part of the fan 200. Therefore, a gap of a predetermined height is formed between the heat exchanger 100 and the upper fan casing 71. The lower end of the junction of the bypass passages described later faces this gap. The upper end of the lower fan casing 72 is joined to the inner surface of the lower region of the rear side panel 35 that faces the vicinity of the lower end of the heat exchanger 100.

3 is a schematic longitudinal sectional view including the front and rear bypass holes 34b and 35b. A bypass passage 80 consisting of a substantially T-shaped pipe is formed on the right side in the lower part of the casing 2 so that the indoor air sucked into the casing 2 from the front bypass hole 34b or the rear bypass hole 35b flows toward the fan 200 without passing through the heat exchanger 100. Specifically, the bypass passage 80 has a front bypass passage 81 whose front end is joined to the inner surface of the front side panel 34 around the periphery of the front bypass hole 34b and extends substantially horizontally rearward to the center in the front-rear direction, a rear bypass passage 82 whose rear end is joined to the inner surface of the rear side panel 35 around the periphery of the rear bypass hole 35b and extends substantially horizontally forward to the center in the front-rear direction, and a junction 83 in which the rear end of the front bypass passage 81 and the front end of the rear bypass passage 82 are connected at the center in the front-rear direction in the casing 2 and extend downward. Therefore, the front bypass passage 81 corresponds to the bypass passage on one side, and the rear bypass passage 82 corresponds to the bypass passage on the other side.

At the lower end of the junction 83, a flow hole 84 is opened, which communicates with the space between the heat exchanger 100 and the upper fan casing 71 described above. A thermocouple S, which is a temperature sensor, is inserted into the junction 83. The temperature detected by the thermocouple S is output to a control device (not shown).

Figure 6 (a) is a schematic side view showing the flow of indoor air when the rear side of the fan convector 1 is installed on the wall surface inside the room. When the outer plate 6 is attached to the casing body 3 with the first outer plate panel 61 positioned on the front side, indoor air is sucked into the casing 2 from the front side through the suction section 7 consisting of the outer opening 65 of the first outer plate panel 61 and the front opening 40 of the casing body 3. The space in front of the heat exchanger 100 in the casing 2 where the suction section 7 is located is blocked from the lower space in the casing 2 where the fan 200 is housed by the lower outer plate panel 63 described above, so the indoor air sucked in from the suction section 7 passes through the heat exchanger 100 from the front to the rear along the air passage formed by the operation of the fan 200, flows from the rear of the heat exchanger 100 in the casing 2 toward the fan 200 below, and warm air is blown out into the room from the blowing section 4 provided at the lower part of the front side of the casing 2.

In addition, a part of the indoor air sucked in through the outer opening 65 of the first outer plate panel 61 flows into the front bypass passage 81 provided in the casing 2 from the front bypass hole 34b. Since the circulation hole 84 provided in the junction 83 faces the gap between the lower end of the heat exchanger 100 located upstream of the fan 200 and the upper fan casing 71, the indoor air sucked into the front bypass passage 81 is blown out through the junction 83 into the gap and flows toward the fan 200 without passing through the heat exchanger 100. In addition, since the circulation hole 84 of the junction 83 faces the gap, it is difficult for the heated air that has passed through the heat exchanger 100 to flow into the circulation hole 84 through the gap. As a result, the temperature of the indoor air can be detected by the thermocouple S provided in the junction 83.

Next, referring to FIG. 4, the configuration when the fan convector 1 is installed away from the wall surface of the room will be described. As described above, the front and rear side panels 34, 35 of the casing body 3 are provided approximately symmetrically in the front and rear directions with respect to the configuration other than the blowing section 4. In addition, the first and second outer panel 61, 62 of the outer panel 6 have approximately the same size and shape. Therefore, when the outer panel 6 is attached to the casing body 3 with the first outer panel 61 having the outer opening 65 positioned at the rear side, the first outer panel 61 is fitted into the rear recess 38 of the rear side panel 35 of the casing body 3, and the second outer panel 62 is fitted into the front recess 37 of the front side panel 34 of the casing body 3. Therefore, in this mounting form, the front side of the casing 2 is formed by the lower region of the front side panel 34 and the second outer panel 62, and the rear side of the casing 2 is formed by the lower region of the rear side panel 35 and the first outer panel 61.

In the state shown in FIG. 4, the outer opening 65 of the first outer plate panel 61 and the rear opening 42 of the rear side panel 35 form an intake section 7 on the rear side of the casing 2 that draws indoor air into the casing 2. The second outer plate panel 62 forms a blocking section 8 on the front side of the casing 2 that blocks the intake of indoor air into the casing 2. In other words, the arrangement of the intake section 7 and blocking section 8 in this mounting form is opposite to that when the outer plate 6 is mounted to the casing body 3 with the first outer plate panel 61 positioned on the forward side.

The lower outer panel 63 has a width in the left-right direction that is approximately the same as the opening width of the rear opening 42. Also, FIG. 5 is a schematic vertical cross-sectional view including the front and rear bypass holes 34b, 35b. As shown in FIG. 5, the lower outer panel 63 extends forward from the lower end of the first outer panel 61 so that when the outer panel 6 is attached to the casing body 3 with the first outer panel 61 positioned on the rear side, the tip portion inserted from the lower end of the rear opening 41 into the casing body 3 abuts against the lower end of the heat exchanger 100 from below. As a result, when the outer panel 6 is attached to the casing body 3 with the first outer panel 61 positioned on the rear side, the space behind the heat exchanger 100 in the casing body 3 is blocked by the lower outer panel 63 from the lower space in the casing 2 in which the fan 200 is housed. Therefore, the lower outer panel 63 prevents the indoor air drawn into the casing 2 from the rear side of the casing 2 from short-circuiting and circulating toward the fan 200 below without passing through the heat exchanger 100. Therefore, as described above, the lower outer panel 63 of the outer plate 6 functions as a short-circuit prevention part.

Figure 6 (b) is a schematic side view showing the flow of indoor air when the fan convector 1 is installed away from the wall surface inside the room. When the outer plate 6 is attached to the casing body 3 with the first outer plate panel 61 positioned on the rear side, indoor air is sucked into the casing 2 from the rear side through the suction section 7 consisting of the outer opening 65 of the first outer plate panel 61 and the rear opening 42 of the casing body 3. The space behind the heat exchanger 100 in the casing 2 where the suction section 7 is located is blocked from the lower space inside the casing 2 where the fan 200 is housed by the lower outer plate panel 63 described above, so the indoor air sucked in from the suction section 7 passes through the heat exchanger 100 from rear to front along the air passage formed by the operation of the fan 200, flows from the front of the heat exchanger 100 in the casing 2 toward the fan 200 below, and warm air is blown out into the room from the blowing section 4 provided at the lower part of the front side of the casing 2.

Also, a part of the indoor air sucked in through the outer opening 65 of the first outer plate panel 61 flows into the rear bypass passage 82 provided in the casing 2 from the rear bypass hole 35b. Since the circulation hole 84 provided in the junction 83 faces the gap between the lower end of the heat exchanger 100 located upstream of the fan 200 and the upper fan casing 71, the indoor air sucked into the rear bypass passage 82 is blown out through the junction 83 into the gap and flows toward the fan 200 without passing through the heat exchanger 100. Also, since the circulation hole 84 of the junction 83 faces the gap, it is difficult for the heated air that has passed through the heat exchanger 100 to flow into the circulation hole 84 through the gap. As a result, the temperature of the indoor air can be detected by the thermocouple S provided in the junction 83, as described above.

As described above in detail, according to this embodiment, the blowing section 4 for blowing out warm air is provided at the lower part of the front side of the casing 2, but the suction section 7 for sucking indoor air into the casing 2 and the blocking section 8 for blocking the intake of indoor air into the casing 2 are provided switchably on the front side and rear side of the casing 2, so that the arrangement of the suction section 7 can be changed according to the installation environment of the fan convector 1. In addition, when the suction section 7 is arranged on the front side, the blocking section 8 is arranged on the rear side, and when the suction section 7 is arranged on the rear side, the blocking section 8 is arranged on the front side. Therefore, indoor air is not sucked into the casing 2 from the side where the blocking section 8 is provided, but is sucked into the casing 2 only from the side where the suction section 7 is provided. Therefore, the indoor air sucked from the suction section 7 can be smoothly circulated into the casing 2 along the air passage formed by the operation of the fan 200. As a result, a predetermined heating performance can be achieved regardless of the installation environment of the fan convector 1.

In addition, according to this embodiment, by switching the mounting direction of the outer plate 6 to the casing body 3, the suction section 7 and the cutoff section 8 are positioned on the front side and rear side, respectively, so the positions of the suction section 7 and the cutoff section 8 can be switched with a simple configuration.

In addition, according to this embodiment, even if the arrangement of the suction section 7 and the blocking section 8 is switched between the front side and the rear side, the indoor air sucked into the casing 2 by the lower outer panel 63 flows through the heat exchanger 100 except for the bypass passage 80, so a decrease in heating performance can be prevented.

In addition, according to this embodiment, whether the suction section 7 is disposed on the front side or rear side of the casing 2, indoor air flows into the front bypass passage 81 or rear bypass passage 82 from the side where the suction section 7 is disposed. The bypass passage 80 has a junction 83 where the front and rear bypass passages 81, 82 merge downstream, and the indoor air flowing into the junction 83 flows toward the fan 200 without passing through the heat exchanger 100. Therefore, by disposing a single thermocouple S at the junction 83, the temperature of the indoor air drawn into the casing 2 can be detected whether the suction section 7 is disposed on the front side or rear side. This allows the fan convector 1 to be operated appropriately regardless of the flow direction of the indoor air drawn into the casing 2.

As described above, this embodiment can provide a highly versatile fan convector 1 that is not limited by the installation environment.
