Abstract

PURPOSE:To prevent hot air from flowing to the inside of a front plate by a method wherein the lock end part of a horizontal blade part is inserted in the comb-shaped groove for inserting the horizontal blade of a lowered part and a gap between the lateral frame of a hot air blow-off frame and the front plate is closed with the cut rise part. CONSTITUTION:A lock end part 2a of a horizontal blade 2 is fixed to a lateral frame part 3 of a hot air blow-off frame 1 and a lock end part 2a of each horizontal blade 2 is inserted in a comb-shaped groove 12 for inserting a horizontal blade having a bent lowered part 11 formed in a hot air blow-off opening edge 10 of a front plate 4 disposed at the front of a hot air blow-off frame 1. In this case, the bending width of the lowered part 11 has size enough to reach the lateral frame part 3 of the hot air blow-off frame 1 and the lowered part 11 forms a partition wall. This constitution blocks inflow of hot air to the inner side of the front plate by the lowered part when an obstacle is placed in front of the hot air blow-off port and eliminates a fear of deformation of a part such as a base leg made of resin owing to the increase of temperature.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the structure of a hot air outlet of a hot air heater.

[0002]

2. Description of the Related Art The warm air outlet of a conventionally used hot air heater having a horizontal burner inside and a hot air outlet located at the lower front portion has a horizontal blade 2 as shown in FIG. Between the horizontal frame portion 3 of the warm air outlet frame 1 serving as the louver frame arranged and the front plate (front panel) 4, a gap a corresponding to the protruding width of the locking end portion 2a of the horizontal blade 2 is formed. It has a structure. In addition, the outlet opening 5 of the warm air outlet frame 1 is shown in FIG.
As shown in Fig. 3, the frame has a large structure.

[0003]

Here, when the flow of the warm air c is obstructed by an obstacle, for example, placed in front of the hot air outlet of the warm air heater, which blocks the opening,
This warm air c does not go forward and the locking end 2a of the horizontal blade 2
Flow in the lateral direction along the inside of the front plate 4 through the gap a (see the dotted arrow in FIG. 3) and heat the inside of the front plate 4 more than necessary to raise the internal temperature to nearly 150 ° C. It is a thing. For this reason, there is a risk that the resin base leg on the lower part of the front surface of the instrument will be thermally deformed, and it is necessary to dispose a heat insulating material or the like on the inner plate surface of the front plate, resulting in a complicated structure. Further, in a large state in which all the blowout openings 5 of the warm air outlet frame 1 are opened, the flow of the warm air c exiting the blowout openings 5 is such that the wall d and the floor are installed when the left side of the device and the wall are installed close to each other. Since it flows so as to directly contact the surface e (see the arrow in FIG. 4), there is a risk of raising the temperature of this wall and the floor surface. This means that in a warm air heater equipped with a horizontal burner, the burner 6 and the combustion chamber 7 are located in the upper part of the appliance, and the heat exchanger 8 facing the hot air outlet is U-turned through the combustion gas passage 9. However, since the hot air on one side (the left side in the drawing) becomes high in temperature, the neighboring walls and floor surface are disadvantageously heated more than necessary.

In view of the above situation, the present invention provides a warm air heater that solves the above problems by closing the gap between the hot air outlet frame and the front plate and partially closing the blowout opening. The purpose is to do.

[0005]

According to the present invention, a burner and a heat exchanger are provided inside, and a warm air outlet is provided in the lower portion of the front plate, and a plurality of horizontal blades are provided inside the warm air outlet. In a warm air heater equipped with a wind outlet frame, a cut-and-raised portion having a comb-shaped groove for inserting a horizontal blade is formed at an opening edge of the warm-air blowing opening of the front plate, and the comb-shaped groove for inserting a horizontal blade in the cut-and-raised portion is formed. By inserting the locking end portion of the horizontal blade into the, the gap between the horizontal frame portion of the warm air outlet frame and the front plate is closed by the cut-and-raised portion.

Further, according to the present invention, a burner and a heat exchanger are provided inside, and a warm air outlet is provided at a lower portion of the front plate, and a warm air outlet frame having a plurality of horizontal blades is provided inside the warm air outlet. In the equipped warm air heater, a cut-and-raised portion having a comb-shaped groove for inserting a horizontal blade is formed at an opening edge of the warm-air blowing opening of the front plate, and the horizontal blade is inserted in the comb-shaped groove for inserting a horizontal blade of the cut-and-raised portion. By inserting the locking end portion of the hot air outlet frame, the gap between the horizontal frame portion of the warm air outlet frame and the front plate is closed by the cut-and-raised portion, and the blowing regulation of a predetermined width is provided on one vertical edge of the warm air outlet frame. This is a configuration in which one piece is provided.

Further, in the present invention, a burner and a heat exchanger are provided inside, and a warm air blowout port is provided at a lower portion of the front plate, and a warm air blowout port frame having a plurality of horizontal blades is provided inside the warm air blowout port. In the equipped warm air heater, a cut-and-raised portion having a comb-shaped groove for inserting a horizontal blade is formed at an opening edge of the warm-air blowing opening of the front plate, and the horizontal blade is inserted in the comb-shaped groove for inserting a horizontal blade of the cut-and-raised portion. By inserting the locking end portion of the hot air outlet frame, the gap between the horizontal frame portion of the warm air outlet frame and the front plate is closed by the cut-and-raised portion, and a blowout restricting piece is provided on a part of the lower stage of the warm air outlet frame. This is the configuration provided.

[0008]

As described above, the gap between the horizontal frame portion of the hot air outlet frame and the front plate is closed by the cut-and-raised portion with the comb-shaped groove for inserting the horizontal blade formed on the opening edge of the warm air outlet of the front plate. Therefore, if an obstacle is located in front of the hot air outlet, the forward flow of warm air is blocked and the warm air travels laterally along the horizontal blades and the opening edge of the hot air outlet is opened. Even when the temperature reaches, the warm air does not flow into the front plate because there is a cut-and-raised portion that serves as a partition wall at the opening edge of the hot air outlet. In addition, since one side (left side) of the hot air outlet and the lower outlet are partially restricted by the outlet restriction piece,
Since the amount of hot air blown to the side wall is regulated and the amount of hot air blown to the floor is also regulated, the wall and floor are not heated more than necessary.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings of FIGS. 1 is a plurality of horizontal blades 2 on the front
Is a louver frame which is a louver frame arranged in parallel at a predetermined interval. The locking end portions 2a of the horizontal blades 2 are fixed to the horizontal frame portion 3 of the warm air outlet frame 1, and the horizontal blades 2 The locking end portion 2a is a cut-and-raised portion 1 that is bent at a warm air outlet opening edge 10 of a front plate 4 arranged on the front surface of the warm air outlet frame 1.
1 has a supporting structure that is inserted into the comb-shaped groove 12 for inserting the horizontal blade, and serves as a warm air outlet of the warm air heater. In this case, the bending width of the cut-and-raised portion 11 has a length that reaches the lateral frame portion 3 of the inner hot air outlet frame 1, and the cut-and-raised portion 11 serves as a partition wall. In addition, the blowout restricting piece 13 having a predetermined width on the vertical edge 1a on one side (left side) of the warm air outlet frame 1
Is provided to partially close the outlet, and a part of the lower stage (lower stage outlet) of the warm air outlet frame 1 is also closed by the outlet regulating piece 14 having a predetermined width parallel to the horizontal blade 2 to regulate the outlet direction. It is configured to do.

Explaining this action, when performing a predetermined heating operation, the combustion gas injected by the burner 6 is burned in the combustion chamber 7 and the combustion gas is transferred by the heat exchanger 8 as in the known warm air heater. A fan provided in the heat exchange (upper part of the combustion chamber 7) flows as warm air between the horizontal blades 2 of the warm air outlet frame 1 and out into the room from the warm air blowing opening 5 of the front plate 4.

In this case, the warm air blowing opening portion 5 is provided with a vertically arranged blowing regulating piece 13 on one side (the left side in the drawing) through which the high warm air flows in the warm air blowing frame 1 located inside. Since the outflow at one end of the outlet opening 5 is regulated, even if the warm air heater is installed near the wall side, the blowing direction is regulated and the flow of warm air separates from the wall d, and the wall d is not heated. Further, the warm air blowing opening 5 is arranged below the floor surface e, but the lower part of the warm air blowing opening 5 is provided at the lower part of the warm air blowing frame 1 with a blowing restricting piece 14 laterally arranged. Since the downward blowing direction is regulated, the flow of the portion having a high warm air temperature does not approach the floor surface e, and the floor surface e is not heated more than necessary.

Further, an obstacle or the like is placed in front of the warm air outlet of the warm air heater to block the flow of the warm air c flowing out into the room, and the warm air c flows laterally along the horizontal blades 2. However, the locking end portion 2a of the horizontal blade 2 is guided by the comb-shaped groove 12 of the cut-and-raised portion 11 bent to the front plate 4, and the cut-and-raised portion 11 is a kind of partition wall. It does not flow into the inside of the equipment and does not raise the internal temperature.

[0013]

As is apparent from the above description, the present invention forms a cut-and-raised portion having a comb-shaped groove for inserting a horizontal blade at the opening edge of the warm air outlet of the front plate, and inserts the horizontal blade in the cut-and-raised portion. By inserting the locking end of the horizontal blade into the comb-shaped groove, the gap between the horizontal frame of the hot air outlet frame and the front plate is closed by the cut-and-raised portion, so that there is an obstacle in front of the hot air outlet. When an object is placed, warm air can be prevented from flowing into the inside of the front plate by the cut-and-raised part, and there is no concern that parts such as resin base legs provided on the lower front of the device will be deformed due to temperature rise. Moreover, since it is not necessary to attach a sealing material between the front plate and the horizontal frame portion of the warm air outlet frame, the number of parts can be reduced.

Further, since the oblique blowout of warm air can be restricted by the blowout restricting piece provided on one side vertical edge of the warm air outlet frame, the temperature rise of the wall surface on the left side of the equipment can be suppressed, for example, when it is near the corner of the room. , Can improve safety.

Further, since the blow-off restricting piece provided in a part of the lower part of the warm air outlet frame can restrict the blow of the warm air obliquely downward, the temperature rise of the floor surface in front of the equipment can be suppressed.
