Description

[Technical Field]

[0001] The present invention relates to a range hood. [Background Art]

[0002] Conventionally, it has been known that this type of range hood is disposed above a heating cooker or the like, sucks in air containing oil generated during cooking, and exhausts the air to the outside. Since an impeller is exposed to air containing oil, oil stains and the like easily adhere thereto, and regular cleaning is required. For this reason, range hoods including a cleaning device that jets cleaning water from a nozzle to clean oil stains and the like adhering to the impeller are known (see, for example, Patent Document 1).

[0003] The cleaning device includes a nozzle and a water supply tank, and by providing the nozzle with a water supply motor, the cleaning water stored in the water supply tank is sucked up and jetted from the nozzle. The nozzle is provided from the suction side of the impeller, and diffuses the cleaning water from an injection unit, thereby injecting the cleaning water to a range of the impeller where oil stains easily adhere. [Prior Art Documents] [Patent Documents]

[0004] [Patent Document 1] Japanese Unexamined Patent Application Publication No. 2021-103078 [Summary of the Invention] [Problem to be Solved by the Invention]

[0005] In such a conventional range hood, a nozzle is provided on the suction side of the impeller, and the configuration is such that cleaning liquid is diffused and jetted onto the impeller. For this reason, there has been a problem in that the farther away from the installation position of the nozzle, the smaller the amount of cleaning liquid jetted onto the impeller, which lowers the cleaning performance for areas where oil adheres.

[0006] Therefore, the present invention aims to solve the above-mentioned conventional problems and to provide a range hood that improves the cleaning effect on the impeller by spraying liquid from multiple nozzles. [Means for solving the problem]

[0007] To achieve this objective, a range hood according to one aspect of the present invention comprises a hood, a fan box, a blower, and a cleaning nozzle, wherein the hood is connected to the fan box, the fan box houses the blower, the blower includes an impeller, a fan casing, and a motor, the impeller is provided inside the fan casing, and the motor is connected to the impeller via a rotating shaft, and the cleaning nozzle includes a first cleaning nozzle and a second cleaning nozzle, the first and second cleaning nozzles characterized by spraying liquid toward the impeller, thereby achieving the intended objective. [Effects of the Invention]

[0008] According to the present invention, the cleaning effect on the impeller can be improved. [Brief explanation of the drawing]

[0014] Range hood 1 is a type of exhaust device installed above a cooking appliance (not shown) that discharges air containing oil fumes and odors generated during the cooking process from indoors to outdoors.

[0015] First, the configuration of the range hood 1 will be described.

[0016] As shown in Fig. 1, the range hood 1 includes a hood 2, a fan box 3, a rectifying plate 40, and a tank cover 50.

[0017] The hood 2 is a cover for guiding air containing oily smoke, odor and the like generated in a cooking process to a hood suction port (not shown) provided in the hood 2.

[0018] The fan box 3 is a casing that covers a blower 100 installed inside and an electrical component not shown.

[0019] As shown in Fig. 2, the fan box 3 is installed above the hood 2, and includes an inflow portion 31, an outer shell 32, and a curved portion 33. The inflow portion 31, the outer shell 32, and the curved portion 33 are covers for guiding the air that has been guided to the hood suction port to the blower 100.

[0020] The rectifying plate 40 controls the flow AIR of air sucked into the hood suction port. The rectifying plate 40 is disposed below the hood 2. The rectifying plate 40 is disposed so as to cover the hood suction port . The rectifying plate 40 forms a gap between itself and the hood 2 for guiding air to the hood suction port. The velocity of the airflow sucked into the gap formed by the rectifying plate 40 and the hood 2 increases. This allows efficient guidance of air that has been warmed and risen by heating cooking to the hood suction port, so an effect of preventing air containing oil from spreading indoors can be expected.

[0021] The tank cover 50 is a cover for preventing a water supply tank 62 and a drainage tank 63 installed in a storage portion 61 from being exposed to oily smoke.

[0022] As shown in Fig. 3, the blower 100 includes a fan casing 110, an impeller 130, and a motor 140.

[0023] The fan casing 110 is a cover for guiding the airflow drawn in by the impeller 130. The fan casing 110 comprises an outer circumference 111, a motor support portion 112, an intake portion 113, an outlet portion 114, a motor-side surface 115, and an intake-side surface 116.

[0024] The impeller 130 comprises a ring portion 132, a main plate 133, and a blade portion 134. In this embodiment, since the direction of air intake is opposite to the direction of the motor 140 installation position relative to the impeller 130 installation position, the ring portion 132 is divided into a motor-side ring portion 132a and an intake-side ring portion 132b. Furthermore, based on its structural characteristics, the blade portion 134 is divided into a motor-side curved portion 134a, a straight portion 134b, and an intake-side curved portion 134c.

[0025] The motor 140 is connected to the impeller 130 via the rotating shaft 142.

[0026] The motor 140 is fixed to the motor support 112. The impeller rotation pin 141 is installed by passing through the rotating shaft 142. The fixing bracket 131 is sandwiched between the impeller rotation pin 141 and the impeller fixing device 120, and the fixing bracket 131 is fixed to the motor 140. The fixing bracket 131 has a groove of the same shape as the impeller rotation pin 141 where it makes contact, so that it can be fixed in the same position every time. In addition, the rotation of the impeller rotation pin 141 can be transmitted to the fixing bracket 131 by contacting it through the groove. The fixing bracket 131 is fixed to the main plate 133. The rotation of the rotating shaft 142 is transmitted to the impeller rotation pin 141, the fixing bracket 131, and the main plate 133, thereby rotating the impeller 130.

[0027] As shown in Figure 4, the water supply tank 62 is a container for holding the cleaning liquid when cleaning the impeller 130. Since the liquid to be put in the container is water or hot water, a material with high heat resistance is desirable. Also, since the water supply tank 62 containing hot water is held by the worker, a shape that is easy for the worker to hold and does not easily transfer the temperature of the hot water to the handle is preferable.

[0028] The drain tank 63 is a container for holding liquid containing dirt after cleaning the impeller 130.

[0029] The cleaning nozzle 20 comprises a first cleaning nozzle 21 and a second cleaning nozzle 22. The first cleaning nozzle 21 is provided, for example, by penetrating the motor-side surface 115 on the discharge section 114 side. The second cleaning nozzle 22 is provided, for example, by penetrating the suction-side surface 116 on the discharge section 114 side. The first cleaning nozzle 21 is connected to the first tube 64. The second cleaning nozzle 22 is connected to the second tube 65.

[0030] The first tube 64, the second tube 65, and the connecting part 67 are connected to the branching part 66. The first tube 64 and the second tube 65 are connected to one end of the connecting part 67 via the branching part 66. The other end of the connecting part 67 is connected to the water supply motor 68. The water supply motor 68 is connected to one end of the suction part 69. The other end of the suction part 69 is installed inside the water supply tank 62.

[0031] The first tube 64, the second tube 65, the branch section 66, the connecting section 67, and the suction section 69 should all be made of heat-resistant materials, considering that hot water will pass through them. Furthermore, since they will be installed inside the range hood 1 for a long period of time, it is desirable that they be made of long-lasting materials that are less susceptible to deterioration due to heat.

[0032] The drainage attachment 60 is installed on the motor side surface 115 and the outer circumference 111. The drainage attachment 60 includes a drain valve (not shown), and by controlling the opening and closing of the drain valve, the timing and amount of the liquid containing dirt after cleaning the impeller 130 that is discharged into the drainage tank 63 can be adjusted to prevent spillage. The drainage attachment 60 is fixed to the motor side surface 115 and the outer circumference 111 with a packing in between. To ensure that the liquid containing dirt is reliably discharged into the drainage tank 63 during drainage, the packing should preferably be made of a highly waterproof material.

[0033] The above describes the configuration of range hood 1.

[0034] Next, the cleaning of the impeller 130 in this embodiment will be described.

[0035] The liquid in the water tank 62 is drawn up from the suction section 69 by the water supply motor 68 and sprayed from each nozzle. The liquid sprayed from each nozzle is, for example, water or hot water, but it may also be water or hot water containing detergent. If water or hot water containing detergent is used, water or hot water without detergent is required separately for rinsing. This is because if detergent remains on the impeller 130, inside the fan casing 110, or in the motor 140, it may affect the paint material being used, so the detergent needs to be rinsed off.

[0036] The liquid sprayed from each nozzle is directed towards the blade section 134, where oil from cooking fumes accumulates. Generally, it is desirable to spray the liquid towards areas where dirt tends to accumulate in order to achieve a high cleaning effect. Therefore, considering the structure of the blower 100 and the blade section 134, the liquid sprayed from the cleaning nozzle 20 is directed towards areas where oil stains and dust adhering to the oil stains tend to accumulate in particular.

[0037] As shown in Figure 5, in the impeller 130 of this disclosure, the motor-side curved portion 134a, where dirt tends to accumulate, is designated as the first target. Similarly, the suction-side curved portion 134c, where dirt also tends to accumulate, is designated as the second target.

[0038] The first cleaning nozzle 21 sprays liquid toward the motor-side curved section 134a (first target), allowing for a concentrated cleaning effect in areas where dirt tends to accumulate.

[0039] The second cleaning nozzle 22 sprays liquid toward the suction-side curved section 134c (second target), allowing for a concentrated cleaning effect in areas where dirt tends to accumulate.

[0040] The liquid sprayed from each nozzle is dispersed as it is ejected. Therefore, the spray range 70 of the liquid sprayed from the cleaning nozzle 20 to each target is as shown in Figure 5, for example.

[0041] It is desirable that the first spray range 70a of the first cleaning nozzle 21 and the second spray range 70b of the second cleaning nozzle 22 intersect. By setting the spray ranges 70 of each nozzle to intersect in this way, it is possible to achieve a high cleaning effect on targets where oil stains tend to accumulate while also providing a cleaning effect to the entire blade section 134.

[0042] Furthermore, the first spray section 21a of the first cleaning nozzle 21 and the second spray section 22b of the second cleaning nozzle 22 are installed, for example, approximately horizontally to each other. Here, "approximately horizontal" does not mean perfectly horizontal. Furthermore, directions tilted within ±15° or ±30° from a perfectly horizontal position are also included in the definition of nearly horizontal.

[0043] Furthermore, if it is anticipated or known that oil stains will concentrate in areas other than the aforementioned targets due to the structure of the blower 100, the cleaning effect can be arbitrarily set by adjusting the spray range 70 of each nozzle.

[0044] For example, in this embodiment, air containing oil stains flows in from the intake section 113 of the fan casing 110, is pushed out perpendicularly to the blade section 134, and is blown out from the outlet section 114. Therefore, due to the difference in the direction of the incoming air and the outgoing air, oil stains tend to accumulate more easily on the motor-side curved section 134a of the blade section 134 than on the intake section 113 side.

[0045] In this case, as shown in Figure 6, for example, by narrowing the first spray range 70a, the force of the liquid sprayed from the first spray section 21a can be increased. This makes it possible to achieve a higher cleaning effect on the motor-side curved section 134a (first target), which is particularly prone to oil stains, with the same flow rate.

[0046] Furthermore, as the first spray range 70a narrows, areas of the blade portion 134 that cannot be cleaned by the liquid sprayed from the first spray section 21a can be cleaned by widening the second spray range 70b sprayed from the second spray section 22b. In this way, a cleaning effect can be applied to the entire blade portion 134.

[0047] As a means of providing a higher cleaning effect to the first target, where dirt tends to accumulate most easily, the flow rate ejected from the first cleaning nozzle 21 and the second cleaning nozzle 22 can also be changed.

[0048] For example, in the configuration shown in Figure 4, by making the inner diameter of the first tube 64 larger than the inner diameter of the second tube 65, the flow rate of the first cleaning nozzle 21 can be increased compared to that of the second cleaning nozzle 22.

[0049] In addition, as shown in Figure 7, for example, by making the flow rate supplied from the first water supply motor 68a connected to the first tube 64 greater than the flow rate supplied from the second water supply motor 68b connected to the second tube 65, the flow rate sprayed from the first cleaning nozzle 21 can be made greater than that from the second cleaning nozzle 22.

[0050] The above-mentioned examples of nozzle spray range and flow rate settings can be combined, allowing designers to achieve high cleaning effectiveness at any desired location, depending on the product's characteristics.

[0051] Drainage during or after cleaning is performed using a drain valve. The impeller 130 may be cleaned by closing the drain valve during cleaning and accumulating cleaning water in the fan casing 110, while rotating the impeller 130. Alternatively, the impeller may be cleaned by rotating the impeller 130 in a continuous flow state without using the drain valve. Furthermore, the impeller 130 may be repeatedly rotated and stopped, so that all blades 134 are hit by liquid sprayed when the impeller 130 is stopped.

[0052] Alternatively, the tubes may be directly connected to the water pipes without using the water tank 62. In this case, the water supply motor 68 and other components may not be necessary. Furthermore, water may be supplied to the water tank 62 directly from the water pipes.

[0053] The following provides further details about this embodiment.

[0054] A range hood 1 according to one aspect of the present invention comprises a hood 2, a fan box 3, and a blower 1. The hood 2 is connected to the fan box 3, which houses a blower 100, and the blower 100 includes an impeller 130, a fan casing 110, and a motor 140, the impeller 130 being located inside the fan casing 110 and the motor 140 being connected to the impeller 130 via a rotating shaft 142, and the cleaning nozzle 20 includes a first cleaning nozzle 21 and a second cleaning nozzle 22, the first cleaning nozzle 21 and the second cleaning nozzle 22 having a configuration that sprays liquid toward the impeller 130.

[0055] With this configuration, liquid can be sprayed from the cleaning nozzle 20 onto the impeller 130, thus effectively cleaning away oily stains adhering to the impeller 130.

[0056] Furthermore, the fan casing 110 may include an intake section 113, an intake side surface 116, an outer peripheral section 111, a motor support section 112, a motor side surface 115, and a discharge section 114. Air drawn in from the intake section 113 by the rotation of the impeller 130 is discharged from the discharge section 114. The intake side surface 116 is the side facing the intake section 113, the outer peripheral section 111 is provided between the intake section 113 and the motor support section 112, the motor support section 112 supports the motor 140, the motor side surface 115 is the side facing the motor 140, the first cleaning nozzle 21 is provided on the motor 140 side, and the second cleaning nozzle 22 is provided on the intake section 113 side.

[0057] With this configuration, the first cleaning nozzle 21 can spray liquid from the motor side 115, and the second cleaning nozzle 22 can spray liquid from the suction side 116, thus enabling simultaneous cleaning of the impeller from both the first cleaning nozzle 21 and the second cleaning nozzle 22.

[0058] Alternatively, the first cleaning nozzle 21 may be configured to penetrate the motor-side surface 115.

[0059] With this configuration, the distance between the first spray section 21a of the first cleaning nozzle 21 and the impeller 130 can be brought closer than simply installing the first cleaning nozzle 21 on the motor side surface 115, resulting in a higher cleaning effect even at the same flow rate. In particular, an even higher cleaning effect can be achieved by making the first spray section 21a protrude into the inside of the fan casing 110.

[0060] Alternatively, the second cleaning nozzle 22 may be configured to penetrate the suction side surface 116.

[0061] With this configuration, the distance between the second spray section 22b of the second cleaning nozzle 22 and the impeller 130 can be brought closer than simply installing the second cleaning nozzle 22 on the suction side surface 116, resulting in a higher cleaning effect even at the same flow rate. In particular, by making the second spray section 22b protrude into the inside of the fan casing 110, an even higher cleaning effect can be achieved.

[0062] Alternatively, the impeller 130 may include a main plate 133, a ring portion 132, and a blade portion 134, wherein the main plate 133 is connected to the motor 140 via a rotating shaft 142, the ring portion 132 includes a motor-side ring portion 132a and a suction-side ring portion 132b, the motor-side ring portion 132a is connected to the main plate 133, and the blade portion 134 includes a motor-side curved portion 134a, a suction-side curved portion 134c, and a straight portion 134b, wherein the straight portion 134b is connected to the motor-side ring portion 132a via the motor-side curved portion 134a, and the suction-side ring portion 132b is connected to the straight portion 134b via the suction-side curved portion 134c, and the first cleaning nozzle 21 may be configured to spray liquid toward the motor-side curved portion 134a.

[0063] With this configuration, the flow rate of liquid sprayed onto the motor-side curved section 134a increases, resulting in a high cleaning effect on the motor-side curved section 134a.

[0064] Alternatively, the second cleaning nozzle 22 may be configured to spray liquid toward the suction-side curved portion 134c.

[0065] With this configuration, the flow rate of the liquid injected into the suction-side curved section 134c is increased, resulting in a high cleaning effect on the suction-side curved section 134c.

[0066] Furthermore, the configuration may be such that the first spray range 70a sprayed by the first cleaning nozzle 21 is narrower than the second spray range 70b sprayed by the second cleaning nozzle 22.

[0067] With this configuration, when the same amount of liquid is sprayed from the cleaning nozzles, the flow velocity of the sprayed liquid is greater at the first cleaning nozzle 21, so the cleaning effect is greater in the first spray range 70a than in the second spray range 70b.

[0068] Furthermore, the amount of liquid sprayed from the first cleaning nozzle 21 may be greater than the amount of liquid sprayed from the second cleaning nozzle 22.

[0069] With this configuration, the amount of liquid sprayed from the first cleaning nozzle 21 to the impeller 130 increases, so the first cleaning nozzle 21 achieves a higher cleaning effect.

[0070] Furthermore, the first spray portion 21a of the first cleaning nozzle 21, which sprays liquid, may be configured to be positioned horizontally relative to the second spray portion 22b of the second cleaning nozzle 22, which also sprays liquid.

[0071] With this configuration, the installation heights of the first cleaning nozzle 21 and the second cleaning nozzle 22 are approximately the same, which has the effect of allowing the liquid to be sprayed in the same way without changing the conditions for spraying the liquid at each installation position.

[0072] Although the range hood according to the present invention has been described above based on embodiments, the present invention is not limited to these embodiments. Within the scope of the present invention, various modifications that a person skilled in the art could conceive of are applied to these embodiments, as well as forms constructed by combining components from different embodiments, are also included without departing from the spirit of the present invention. [Industrial applicability]

[0073] The range hood according to the present invention can provide a range hood with improved cleaning effect on the impeller by spraying liquid from multiple nozzles, and is therefore useful as a ventilation device installed above a cooking appliance or the like. [Explanation of Symbols]
