Description

  The present invention relates to a hot water heater with a blower fan, a so-called fan convector, and more particularly to a structure of an air passage extending from a suction port to a blower outlet, a partition plate that partitions a front panel of a housing, and a joint portion of the blower outlet. is there.

  A hot water heater with a blower fan takes in the air in the room to be heated from a suction port provided on the back of the housing, heats the air with warm water, and directs the heated air from the outlet to the room by the blower fan. It is a heater that blows out.

  As shown in FIG. 2, the conventional hot water heater with a blower fan connects the air inlet 2 provided at the upper back of the housing 1 and the air outlet 4 fixed to the front panel 3 of the housing 1. A heat radiator 6 and a blower fan 7 are provided inside the passage 5, and air heated by heat radiation of the heat radiator 6 is sent to the blower outlet 4 by the blower fan 7, and hot air is sent from the blower outlet 4 to the housing 1. It blows out outside (that is, the room to be heated) (Patent Document 1, Patent Document 2).

  A partition plate 8 is provided between the inlet 2 and the outlet 4 and forms a part of the partition wall of the air passage 5. The connection part 9 of the partition plate 8 and the blower outlet 4 is closely_contact | adhered so that the warm air inside the air passage 5 may not leak. The partition plate 8 also functions as a heat shield that prevents the front panel 3 from becoming hot due to the heat of the radiator 6.

  Note that warm water supplied from a heat source (not shown) circulates inside the radiator 6, and heat exchange is performed between the warm water and air sucked from the suction port 2 to heat the air.

However, in this conventional hot water heater with a blower fan, the air outlet and the partition plate are configured as separate parts, and they are stacked so that the warm air in the air passage does not leak, so at the start of operation and at the end of operation, Due to the difference in temperature or coefficient of thermal expansion between the partition plate and the air outlet, there is a problem that the air outlet and the partition plate are relatively displaced and rubbed to generate abnormal noise, which makes the user uncomfortable. It was. Although air outlet and the partition plate are are superimposed so tight hot air inside the device occurs inevitably a slight leakage of warm air for the partition plate and the air outlet and is configured in a separate component temperature An increase was occurring.
This invention is made in view of such a problem, prevents generation | occurrence | production of the noise by friction of the blower outlet and partition plate of a warm water heater with a ventilation fan, and a quiet warm water heater with a ventilation fan is made. It is intended to provide. It is another object of the present invention to prevent the warm air from leaking from the joint between the partition plate and the air outlet and suppress the temperature rise inside the device.

  A first configuration of a hot water heater with a blower fan according to the present invention includes hot water in an air passage that connects a suction port provided on the back surface of the housing and a blower outlet provided on the front surface of the housing. A radiator that radiates heat of the hot water to the air inside the air passage, a blower fan that sends out the air heated by the radiation of the radiator to the outlet, the radiator and the housing In the hot water heater with a blower fan having a partition plate that partitions between the front panels, the outlet and the partition plate are configured integrally.

With this configuration, the hot water heater with a blower fan of the present invention does not rub between the air outlet and the partition plate, so that no abnormal noise is generated.

  A second configuration of the hot water heater with a blower fan according to the present invention is characterized in that, in addition to the first configuration, the outlet and the partition plate are integrally formed of plastic.

With this configuration, the number of parts of the hot water heater with a blower fan of the present invention is reduced.

  A third configuration of the hot water heater with a blower fan according to the present invention is characterized in that, in addition to the first or second configuration, a control board is attached to the front surface of the partition plate.

  With this configuration, since the control board is isolated from the hot air, the temperature rise of the control board is suppressed.

  A fourth configuration of the hot water heater with a blower fan according to the present invention is characterized in that, in addition to the first to third configurations, a movable guide blade is provided in the outlet.

  With this configuration, the hot water heater with a blower fan of the present invention can freely change the direction of the hot air. Note that the movable guide vanes are not limited to those in which the flow of warm air is swung in the left-right direction, but also include guide vanes that change the flow in the vertical direction.

  According to the present invention, since the blower outlet and the partition plate of the hot water heater with the blower fan are integrally configured, generation of abnormal noise due to friction between the blower outlet and the partition plate is prevented, and the hot water heater with the blower fan is provided. Silence is improved. Moreover, since the said blower outlet and the partition plate were integrally molded with the plastic, there exists an effect which reduces the number of parts of a warm water heater with a ventilation fan, and reduces manufacturing cost. Moreover, the temperature rise inside the apparatus due to leakage of warm air from the joint between the partition plate and the outlet is eliminated. Further, since the control board is attached to the front surface of the partition plate, the control board is isolated from the hot air, and the temperature rise of the control board is suppressed. For this reason, the failure of the control board due to the temperature rise is reduced, and the reliability is improved. Moreover, since the movable guide blade was provided in the said blower outlet, the direction of the warm air which the said blower outlet blows out can be changed freely, and heating efficiency improves.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

  FIG. 1 is a cross-sectional view of a hot water heater with a blower fan according to an embodiment of the present invention. This hot water heater with a blower fan is provided with a suction port 2 at the upper back of the housing 1 and a radiator 6 and a blower fan 7 inside the air passage 5 in the same manner as a conventional hot water heater with a blower fan. The air heated by the heat radiation of the radiator 6 is blown out of the housing 1 by the blower fan 7.

  The air passage 5 is formed by the housing 1 and the partition plate 10, and the partition plate 10 divides the space between the front surface of the housing 1 and the front panel 3 of the housing 1 and the air passage 5, and heat of the hot air flowing through the air passage 5. Is prevented from being transmitted to the space and the front panel 3.

  In addition, an air outlet 11 is integrally formed at the lower part of the partition plate 10, and the air outlet 11 protrudes from the opening 12 cut out at the lower part of the front panel 3 of the housing 1 to the outside of the housing 1. A movable guide vane 13 is attached to the air outlet 11. The movable guide vane 13 can change the direction of the warm air blown from the outlet 11 by changing the angle around the vertical axis.

  Further, a concave portion is provided on the upper front surface of the partition plate 10, and a control board 14 for controlling the movement of the hot water heater with a blower fan is attached inside the concave portion. Thus, since the control board 14 is arrange | positioned in the space isolated from the warm air, the temperature rise of the control board 14 by the heat of warm air can be avoided.

  In addition, the partition plate 10 and the blower outlet 11 are integrally molded with ABS resin, AAS resin, AES resin, or the like.

It is sectional drawing of the hot water heater with a ventilation fan which concerns on the Example of this invention. It is sectional drawing of the hot water heater with a ventilation fan which shows the example of a prior art.
