Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a range hood that incorporates a blower that collects and exhausts oily smoke generated in the kitchen and a water heater that supplies 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. 5, for example. That is, a hood 3 is installed on a wall 4 above the gas stove 2 of the gas appliance stand 1. A fan 5 provided inside the hood 3 sucks oil smoke generated during cooking using the gas stove 2 into the hood 3 through a suction port 6 provided on the entire substantially horizontal lower surface of the hood 3. , and is further discharged from the exhaust port 8 via the exhaust pipe 7 and the fan 5.

On the other hand, inside this hood 3, a burner 9, a heat exchanger 10,
A water heater 12 consisting of an operating mechanism 11 is built-in. This water heater 12 has an air supply port 13 for combustion air opened at the front of the hood 3, and an exhaust pipe 14 for combustion exhaust gas at a branch part 1.
It is connected to the exhaust pipe 7 via the exhaust pipe 5 and shares the range hood's exhaust pipe. 16 is a damper provided at the branch part 15;
Exhaust pipe 14 on the water heater 12 side and exhaust pipe 7 on the range hood side
This is used to switch between the two.

Problem to be Solved by the Invention While cooking on the gas stove 2 using the above range hood,
If the oil accidentally catches fire and a large flame rises, the suction port 6
It immediately goes into the hood 3. Although the fan 5 exhausts the air through the exhaust pipe 7, there is a limit to the exhaust power, and flames are temporarily trapped inside the hood 3.
The water heater 12 provided integrally within the hood 3, especially the operation mechanism 11, would also be heated, which was undesirable. In particular, when the water heater 12 was also used at the same time, the temperature of the water heater 12 itself rose due to the combustion of the burner 9, which caused the temperature of the water heater 12 to rise even more, which was dangerous. .

In addition, the oil smoke generated during cooking on gas stove 2 should be removed from hood 3.
Although the fan 5 sucks the smoke from the suction port 6 of
When the hood 3 collides with the hood 3, there is some resistance and the hood 3 spreads slightly from the bottom surface of the hood 3 to the left and right and to the front side and escapes. For this reason, there is a risk that oily smoke will adhere to the air supply port 13 on the front of the hood 3, and the air supply port 13 will be gradually blocked. There was a risk of interfering with the combustion of burner 9.

Furthermore, if the exhaust pipe 14 of the water heater 12 is not airtightly connected to the branch part 15, other parts of the hood 3 may be connected to the branch part 15.
Air flows into the hood 5, which not only hinders the exhaust of the water heater 12 but also reduces the original exhaust capacity of the hood 3.

The present invention solves the problems of the prior art,
It protects the water heater installed in the hood from being heated by flames that accidentally occur during cooking, making it safe to use, and also protects the water heater intake from oil smoke, making it easier to clear the water heater's exhaust path. This allows for installation. Furthermore, when installed in the kitchen, even if the hanging cabinets are installed on the left and right sides, the air intake port for the water heater can be taken in without being blocked.

Means for Solving the Problems In order to solve the above problems, the present invention has an exhaust port, a front plate that is inclined toward the front toward the upper part, and an intake port located at the upper end of this front plate, and the front plate is provided inside the front plate. The water heater includes a box-shaped hood body with a face plate and a suction port facing each other and a blower installed therein, and a water heater installed inside the hood body adjacent to the blower. A duct is provided at the rear side of the hood body to guide intake air from the intake port at the rear of the upper surface of the hood body to the lower part of the combustion chamber of the water heater; It is located near the suction port of the blower via a duct.

Function The present invention protects the water heater from a large flame accidentally generated in the kitchen by using the above-mentioned means, which is the front plate that is inclined toward the front toward the top of the hood body and the intake port located at the L end of the front plate. be able to. In addition, the intake port for the water heater is located at the rear of the top of the hood body, and there is an intake duct located at the rear of the hood body that guides the intake air to the lower part of the combustion chamber, so it is not blocked by oil smoke, etc. The exhaust port for the water heater also needs to be opened near the air intake port of the blower, so it can be easily assembled.

EXAMPLE An example of the present invention is shown in FIGS. 1, 2, and 3.
The explanation is based on Figure 4. In the figure, the hood body 2
1 includes a rear plate 21m, a bottom plate 21b, a top plate 21a,
The side plate 21d and the front plate 21e form an inverted shape. The hood body 21 is provided with a blower 24 having an inlet 23 therein, has an inlet 25 above the front plate 21a of the hood body 21, and is attached with a removable filter 26. Blower 2
The exhaust gas from the exhaust port 27 is exhausted to the outside through the exhaust duct 28. The water heater 29 is built into the hood body 21 in parallel with the blower 4.

The water heater 29 includes a case 30, a burner 31, and a heat exchanger 3.
2. Consists of a gas block 33 and a water block 34.

An intake duct 35a is provided along the rear plate 21m from the intake port 35 opened in the top plate 21c of the hood main body 21, and the lower end opening of this duct 35a opens at the back of the case 30 and enters the case 30. Air is sucked in and supplied to the

Furthermore, the combustion exhaust gas from the burner 31 exits from the exhaust port 36 to the internal space of the hood body 21 via the duct 37, and the exhaust port 36 is located near the suction port 23 of the blower 24, and the hood body Since the airflow flowing in from the intake port 25 of the hood body 21 is flowing toward the intake port 23 in the same way, the airflow does not spread into the internal space of the hood body 21, and is drawn into the blower 24 and flows through the exhaust port 27 into the exhaust duct 2B. is reliably discharged through the

In the water heater 29, water flows when the hot water tap 43 is opened, and in response to a signal detected, the control unit 41 operates the blower 24 in the mode set on the operation unit 42, and then switches the switch 44 of the operation unit 42. By pressing the button, gas flows from the gas pipe 38 to the burner 31 and burns, and water from the water pipe 40
The water passes through the heat exchanger 32, the hot water pipe 39, the hot water tap 43, and flows into the water tank 4B.

When installed and used, it is placed above the gas stove 45 placed on the cooking table 22, and a hanging cabinet 47 is provided on the side. The oil smoke from the cooking device 46 is sucked into the filter 26 along the front plate 218 as streams 4B and 50 on the front plate 2115 causing the Coanda effect.

Effects of the Invention As described above, in the present invention, since the water heater is covered using the front plate of the cord main body that causes the Coanda effect, and the intake port is located at the upper end of the front plate, there is no possibility of accidentally entering the kitchen. Even if a large flame rises, it will hit the front panel and the flame will not directly and easily enter the hood body, so the water heater can be safely protected, and the protective structure utilizes the unique structure of the hood body. Because we do this, we can do it cheaply.

In addition, an intake port for the water heater is opened at the rear of the upper surface of the hood body, and an intake duct located at the rear of the cord body guides the intake air from the intake port to the lower part of the combustion chamber of the water heater. is located near the air inlet of the blower, and the front plate reliably draws oil smoke, etc. into the intake port of the hood body, and hardly spills to the other side, especially to the rear of the top surface. Since the intake port will no longer be blocked,
The operation of the water heater can be stabilized. Additionally, even if hanging cabinets are installed on the left and right sides, the water heater's intake port will not be blocked, making installation easy. Furthermore, since the water heater's exhaust path does not need to be securely connected to the blower's suction port, assembly work is simplified, productivity is improved, and costs are reduced.
