Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a range hood for an IH cooking heater (electromagnetic induction heating cooker).

[0002]

2. Description of the Related Art Conventionally, gas appliances using city gas, LP gas, or the like as fuel have been generally used as cooking appliances. Combustion generates harmful substances such as carbon dioxide and carbon monoxide, so that sufficient ventilation must be ensured, and this has resulted in disruption of room air conditioning. Therefore, the need for electromagnetic induction heating cookers (IH cooking heaters) is gradually increasing in addition to electric stoves that do not generate harmful substances during cooking.

A gas appliance generates combustion gas together with steam from a cooking pot or the like, and heats the hood by the heat of the combustion gas. An electric stove warms the hood by the heat of the rising airflow. This both reduces the humidity of the steam. Therefore, no condensation occurs. However, since the above-mentioned IH cooking heater does not involve a combustion gas or an updraft, steam generated during cooking adheres to the hood body and forms dew, which gradually becomes large particles, and eventually drops on the IH cooking heater. I will make it dirty.

[0004]

DISCLOSURE OF THE INVENTION The present invention has been made in view of the above-mentioned conventional circumstances, and has a technical problem in that a portion to which steam is actively adhered is formed by a slope, and the condensation is dropped on the slope. It is to be guided downward without receiving water so that it can be drained.

[0005]

According to the technical means taken in order to solve the above-mentioned object, a steam attaching means is provided on a hood body which is opened downward, and the steam attaching means attaches steam generated during cooking. The gist of the present invention is to form a slanted surface that guides downward without dripping, and that a water receiving means is connected to the steam attaching means. Here, a panel can be used as the inclined surface steam attaching means. If the panel has been subjected to a hydrophilic treatment, an angle of inclination of at least 5 degrees is required to guide dew condensation without dripping, and if the panel is subjected to a water-repellent treatment, no condensation is dripped. At least 15 to guide to
It is necessary at an inclination angle of more than degrees. In the case of a panel that has not been subjected to both treatments, an inclination angle of at least 30 degrees is required to guide dew condensation without dripping.

[0006] Thus, steam generated during cooking is positively attached to the inclined steam attaching means, and is guided downward without dropping dew by the guiding action of the inclined surface to the water receiving means. Water is allowed to drain from the receiving means.
In addition, cooking odor and the like generated during cooking are sucked in from a gap secured between the hood body and a panel end serving as steam attaching means.

If a water reservoir is provided so as to communicate with the lower end of the inclined steam-applying means and the water reservoir can be removed, it is preferable for draining the collected water.

Further, a water receiver is provided in communication with the lower end of the inclined steam-applying means, and a drain pipe is provided in the water-receiver so that water collected by the steam-applying means can be drained sequentially. Is also effective.

When a grease filter is arranged behind the steam applying means and above the container, dew adhering to the grease filter can also be collected in the container, thus simplifying the structure. It is convenient.

[0010] Further, the inclined surface steam attaching means is constituted by a plurality of panels parallel to a direction orthogonal to the depth direction of the hood body, and adjacent ends of the panels have lower panels with respect to upper panels. Is preferably configured to overlap below through a gap. The number of panels to be used is not limited to two or three, and a larger number of panels can be freely used.

That is, the gap formed between the overlap of the upper panel and the lower panel reduces the concentration of the airflow only in the gap secured between the hood body and the panel end serving as the steam attaching means. By avoiding it, it is dispersed also in the gap between the hood body and the panel and leads to the grease filter.

If the panel is configured to be detachable from the hood, it is convenient to clean the inside of the hood and the exhaust device behind it.

[0013]

Next, an embodiment of the present invention will be described with reference to the drawings. 1 to 3 show a first embodiment of a range hood for an IH cooking heater according to the present invention in FIG.
5 and 6 show the second embodiment, FIGS. 6 and 7 show the third embodiment, and FIG. 8 shows the fourth embodiment. First, the first embodiment will be described. Reference numeral A is a range hood.

The range hood A is provided with a hood body 1, an inclined steam attaching means 2 provided in the hood body 1, a water receiving means 3 at a lower end of the steam attaching means 2, and a back of the steam attaching means 2. The exhaust device 4 is provided.

The steam applying means 2 is composed of a plurality of panels 12 having at least a surface subjected to a hydrophilic treatment or a water repellent treatment. In the present embodiment, two panels whose front and back surfaces are subjected to hydrophilic treatment are used. Hereinafter, the upper panel is referred to as a first panel 12a, and the lower panel is referred to as a second panel 12b.

The first panel 12a has an upright edge 12a-2 except for one edge of a rectangular plate 12a-1 slightly narrower than the lateral width of the hood body 1, and a guide edge 12a at the other edge. −
3 is bent downward, and the parallel upper edges 12a-
The stay 5 is formed so as to protrude at an appropriate interval from the second and second 12a-2.

The second panel 12b is connected to the first panel 12
As in the case of a, the rising edge 12b-2 is bent from the periphery of the curved plate 12b-1 slightly narrower than the lateral width of the hood body 1 and the gentle slope 12b-3 is bent at one edge. Become
Both upper edges 12b parallel to the first panel 12a

The first panel 12a and the second panel 1 described above.
2b of the stay 5 has one side rising edge 12a-2, 12b-
2 is supported integrally with the other side via an armature 6, one of which is inserted into a concave portion 11 a which is recessed on both side surfaces 11 of the hood body 1, and the other is protruded and retracted by the action of the elastic body 6. By doing so, each panel 12a, 1
2b is removable (see FIG. 2).

The first panel 12a is arranged at a distance from the top surface 21 of the hood 1 so as to face an area where steam rising from the cooking vessel mainly adheres, and the guide edge 12a-3 is provided.
Hood body 1 with the inclination angle of 5 degrees or more with
Is inclined downward in the direction of the back surface 31 of the camera. Needless to say, in the case of the one subjected to the water repellent treatment, it is inclined at an inclination angle of 15 degrees or more.

The second panel 12b is connected to the first panel 12
The upper end is overlapped with the lower end of a through a gap S, and is inclined obliquely downward toward the back surface 31 of the hood body 1 with the gentle inclined edge 12b-3 as the lower end. is there. The second panel 12b naturally has an inclination angle of 5 degrees or more when subjected to a hydrophilic treatment, and an inclination angle of 15 degrees or more when subjected to a water-repellent treatment. It goes without saying that it is inclined.

Here, the hydrophilic treatment refers to a treatment for providing a hydrophilic baking paint as a surface layer, and is a well-known treatment method in which dew condensation due to steam adhering is stopped in small grains to easily flow down. In order to guide the dew condensation due to steam without dripping, an inclination angle of at least 5 degrees is necessary, and for those subjected to water repellency treatment,
Since the dew condensation particles are large, an inclination angle of at least 15 degrees is required. This is empirical and requires at least a 30 degree tilt angle with untreated panels.

As shown in FIG. 1, the hood body 1 surrounds the above-mentioned first and second panels 12a and 12b from above and is behind the steam attaching means 2 composed of the first and second panels 12a and 12b. It has a deformed box-like shape having a volume large enough to accommodate the exhaust device 4 in the space 7 and having a tapered tip with an open lower portion.
1, 11, a back surface 31, a top surface 21, and a partition surface 41. The partition surface 41 is located immediately below the lower end of the steam attaching means 2 composed of the first and second panels 12a and 12b. The area extends from the rear surface 31 to the front.

In the present embodiment, the water receiving means 3 is constituted by a detachable water reservoir which is disposed on the upper surface of the front end of the partition surface 41 so that the lower end of the second panel 12b faces.
The first and second panels 12a and 12b are formed in a slender shape having a length substantially equal to the width of the hood body 1 so that dew condensation guided by the front and back surfaces of the first and second panels 12a and 12b can be collected. It is to be noted that the water reservoir may be a water receiver, the water receiver may be of a detachable type or a fixed type, and the drainage water 3 may be drained each time by a drain pipe 3 'to communicate therewith.

In the present embodiment, the exhaust device 4 uses a multi-blade fan, and the grease filter 14 is disposed in front of the exhaust device 4 and above the water reservoir 3 so as to be removable.

The range hood for an IH cooking heater (electromagnetic induction heating cooker) thus configured causes steam generated during cooking to adhere to the surfaces of the first and second panels 12a and 12b. Condensation that adheres to the surface of the first panel 12a and flows down is reduced via the overlap margin.
The dew formed on the surface of the second panel 12b is collected by the water reservoir 3 along the back surface of the second panel 12b. Exhaust air is provided between both side surfaces 11, 11 of the hood body 1 and the left and right ends of the first panel 12a and the second panel 12b, between the front end of the hood body and the front end of the first panel 12a. Is performed from the gap S secured between the first panel 12a and the second panel 12a. The grease filter 14 absorbs and removes oils and fats contained in the cooking smell, and is connected to the exhaust device 4. From the exhaust duct 24 to the outside. The condensation formed on the inner surface of the top surface 21 of the hood body 1 drops on the back surfaces of the first panel 12a and the second panel 12b and is guided similarly to the water reservoir 3, and steam adhering to the grease filter 14 is removed. Water is condensed and collected directly in the container 3.

When cleaning the interior of the hood 1, the exhaust device 4, and the grease filter 14, the first and second panels 12
a, 12b are removed from the hood body 1 to cope with the problem. Of course, it is also possible to wash with water if the panel itself is removed.

Next, a second embodiment will be described. In this embodiment, the first panel 1 to which steam mainly adheres is used.
2a is further subdivided into a plurality of panels 12a 'parallel to a direction orthogonal to the depth direction of the hood body 1.

The configuration in which the lower panel 12a 'overlaps the lower panel 12a' below the upper panel 12a 'via the gap S is the same as in the above-described embodiment, and the structure of the panel 12a' And top panel 1
There is no change in the function of guiding dew condensation generated by steam being sequentially attached to the lower panel 12a 'from 2a'.

The difference between the present embodiment and the first embodiment is that cooking odor and the like are sucked in from the gaps S formed between the panels 12a 'and 12a'. The gap S secured between the front end of the first hood 1 and the first panel 12a is secured between the side surfaces 11, 11 of the hood body 1 and the left and right ends of the first panel 12a and the second panel 12b. The point is that it is possible to prevent the intake air from being concentrated in the gap S and to reduce the amount of steam attached to the top surface 21 of the hood body 1.

In the present embodiment, the first panel 12a is constituted by a plurality of panels 12a 'which overlap to form the gap S. As a result, as shown in FIG. Sufficient exhaust efficiency can be maintained without intentionally providing a gap S for intake between the two side surfaces 11 and 11.

Next, a third embodiment will be described. In this embodiment, a conventionally known boot-type range hood can be used as a range hood A for an IH cooking heater.

Although the steam attaching means 2 is constituted by the first panel 12a and the second panel 12b, it is the same as the first embodiment described above. The upper end of a second panel 12b having the same inclination as that of the first panel 12a is provided over the lower side of the first panel 12a with a gap S therebetween on both sides of the first panel 12a. A structure in which steam generated during cooking is attached to the surface of the first panel 12a and the surface of the second panel 12b, respectively, and the water is collected in the water reservoir 3 without dropping dew due to the inclination guide. It has become.

The water reservoir 3 is detachably supported on a support plate 61 laid between the side surfaces 11 of the hood body 1 directly below the grease filter 14 so that the water container 3 can be removed from the front surface of the first and second panels 12a and 12b. The dew passing through the back surface and the surface of the grease filter 14 is collected.

In the present embodiment, the first and second panels 12
The steam generated by cooking adheres equally to the first and second panels 12a and 12b, and the intake air is supplied to the gap S between the front plate 51 and the first panel 12a, both sides of the hood body 1 and the first and second panels 12a and 12b.
The gap S between the left and right ends of the first panel 1 and the first panel 1
This is performed from the gap S between the second panel 12a and the second panel 12b.

Of course, when cleaning the inside of the hood body 1, the exhaust device 4, and the grease filter 14, after removing the front plate 51,
What is necessary is just to remove the second panel 12b from the hood body 1, and it is possible to wash it by removing the first panel 12a from the front plate 61.

The fourth embodiment will be described briefly. In this embodiment, the steam attaching means 2 is constituted by the same inclined first panel 12a and second panel 12b which have been subjected to hydrophilic treatment. And a range hood A for an IH cooking heater in which an exhaust device (not shown) is accommodated in a sink cabinet or the like, and the exhaust device and the range hood are connected by a communication duct 34.
