Abstract

PURPOSE:To prevent dewing from generating in a range hood due to a high temperature exhaust burning gas by extending a duct from above a heat exchanger and positioning an exhaust port in the neighborhood of the suction port of a blower. CONSTITUTION:A hot water feeder 29 has a suction port 35 communicating with a casing 30, being projected from the lower portion of the left side face plate 21d of a hood body 21 and opened, draws the burning air of a burner 31. The hot water feeder 29 has an exhaust port 36 positioned in the neighborhood of the suction port 23 of a blower 24 without being connected thereto by a duct 37 for exhausting the exhaust burning gas of the burner 31. The exhaust burning gas of the burner 31 does not spread in a space inside the hood body 21 from an exhaust port 36 via the duct 37 but is blown by the blower 24 to be surely discharged from an exhaust port 27 via an exhaust duct 28. Further, since the exhaust ducts themselves are heated by exhaust heat generated in cooking even when a hot water supply is stopped, dewing is not generated in the hood body and the exhaust ducts themselves, preventing an apparatus from being damaged by dewing.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a range hood incorporating a blower for exhausting oily smoke generated in the kitchen and a water heater for supplying hot water for use in the kitchen.

BACKGROUND OF THE INVENTION In recent years, in order to make effective use of kitchen space, there has been a demand for various devices installed in the kitchen to be more efficient, more complex, and more compact. For this reason, conventional range hoods installed in kitchens have been constructed as shown in FIG. 4, for example. In other words, 1 is a water heater such as a gas instantaneous water heater that has a burner 3, a heat exchanger 4, a water supply valve 5, a gas supply valve 6, etc. built into a case 2, and is installed inside a hood body 7 adjacent to a fan 8. It is. The water heater 1 also has an exhaust port 9 for discharging combustion exhaust gas from the burner 3. The combustion exhaust gas is sucked into the fan 8 and exhausted from the hood exhaust port 10.

On the other hand, the hood main body 7 is installed above a gas stove used in the kitchen, and the oil smoke generated during cooking using the gas stove is sucked by the fan 8 from the suction port provided in the hood main body 7, and the hood It is discharged from the exhaust port 10.

Problems to be Solved by the Invention In the range hood described above, combustion exhaust gas combusted by the burner 3 of the water heater 1 is discharged from the exhaust port 9 into the hood body 7, is sucked by the fan 8, and is discharged outdoors from the hood exhaust port IO. It is discharged. However, once the high temperature combustion exhaust gas is discharged from the exhaust port 9, the fan case 12
The air is then sucked in by the fan 8. However, depending on the fan capacity and the airtightness of the hood body 7, the water may flow along the top plate 11 and later be sucked into the fan 8. As mentioned above, the high-temperature combustion exhaust gas discharged from the exhaust port 9 is once discharged into the hood body 7 and then sucked by the fan 8, so in the process it is cooled and the hood body 7 is cooled, including the top plate 11 and fan case 12. Condensation was condensing inside, causing damage to the equipment.

The present invention solves these conventional problems and aims to prevent dew condensation inside a range hood caused by high-temperature combustion exhaust gas.

Means for Solving the Problems In order to solve the above problems, the present invention includes a box-shaped hood body having an exhaust port and an intake port, and having a blower installed inside;
The hood body includes a water heater installed adjacent to the blower, and the water heater has a duct extending from the top of the heat exchanger and an exhaust port located near the suction port of the blower. Found in a built-in range hood.

Effect of the present invention By using the above-described means, high-temperature combustion exhaust gas is quickly discharged outdoors from the exhaust port through the blower without being retained in the hood body.

EXAMPLE An example of the present invention will be described below with reference to FIGS. 1 to 3. 21 is a rear plate 21a, a bottom plate 21b, and a top plate 21.
c, the box-shaped hood body is airtightly formed by left and right side plates 21d and a front plate 21e.

The hood main body 21 is located at the upper right side of the interior, and has an air blower 8124 made of a centrifugal fan inside with the suction port 23 facing the front plate 21e. Reference numeral 25 denotes an intake port, to which a filter 26 for oil smoke is removably attached.

Reference numeral 27 denotes an exhaust port opened on the upper surface +ff121c of the hood main body 21, to which an exhaust duct 28 is connected. 29 is a water heater such as a gas instantaneous water heater that has a burner 31, a heat exchanger 32, a water supply valve 33, a gas supply valve 34, etc. built into the case 30;
It is installed inside the hood body 21 on the left side, adjacent to the blower 24. The water heater 29 has an inlet port 35 for inhaling combustion air from the burner 31 that communicates with the inside of the case 30 and projects from the lower part of the left side plate 21d of the hood body 21. Further, the water heater 29 is not connected to the suction port 23 of the blower 24 through a duct 37 for discharging combustion exhaust gas from the burner 31, but has an exhaust port 36 located near the suction port 23 of the blower 24.

The duct 37 has one end connected to the exhaust side of the upper part of the heat exchanger 32, and the other end, the exhaust port 36, is arranged in front of the blower 24 located below the exhaust side of the heat exchanger. 38 is a water supply pipe, 39 is a hot water supply pipe, and 40 is a gas supply pipe, which are led out from the bottom plate 21b of the hood body 21. 4
Reference numeral 1 denotes a control unit provided at the front end 42, which is the frontmost part of the hood body 21. By pressing a pressing part 44, the blower 24 can be rotated and stopped, and as shown in FIG. When the tap 43 is opened, water flows, which is detected by the sensor, and the blower 24 is automatically rotated, after which the presser 44 is pressed to ignite the burner 31 and control the hot water supply. 45 is a gas stove, 46 is a cooking pot, 47 is a storage cupboard, 48 is a sink,

The gas flows and burns, and hot water is supplied by the heated heat exchanger 32 and discharged from the hot water tap 43. At this time, the combustion air of the burner 31 is sucked into the case 30 from the intake port 35 by the force of the blower 24, and the combustion exhaust gas of the burner 31 is further passed through the duct 37 from the exhaust port 36 to the hood body 2.
This will take you to the interior space of 1. However, due to the fact that the exhaust port 36 is near the suction port 23 of the blower 24 and the airflow flowing in from the suction port 25 of the hood body 21 is also flowing toward the suction port 23, the hood body 21 The air is drawn into the blower 24 and reliably discharged from the exhaust port 27 through the exhaust duct 28 without spreading into the internal space.

Effects of the Invention As described above, in the present invention, the exhaust port of the water heater is located near the suction port of the blower by means of a duct extending from the exhaust side of the heat exchanger, so that high-temperature combustion exhaust gas spreads into the hood body. It is reliably discharged by the blower without any problems.

In addition, even when hot water supply is stopped, the exhaust duct itself is warmed by exhaust heat from cooking, etc., so condensation does not form inside the hood itself or on the exhaust duct itself, preventing damage to equipment due to condensation. .
