Description

本発明は、紫外線ＬＥＤを、それぞれ光触媒が施されたフィルター面に対して傾斜して取付け、前記紫外線ＬＥＤによる紫外線を、該光触媒が施されたフィルターの上面部および両側面部に広く照射できるようにして、紫外線の照射面を広げる一方、小径に絞った通気部によるベンチュリ効果により、該光触媒が施されたフィルターを通過する空気の圧力を高めてフィルターへの接触効率を高めて脱臭効果を高め、更に前記小径に絞った通気部の外側壁面とケーシング内側壁面間に空間部を形成し、該空間部に脱臭器の部品を配設できるようにして、脱臭器の小型化を図るようにした小型脱臭器に関するものである。 In the present invention, the ultraviolet LED is attached to each of the filter surfaces on which the photocatalyst is applied, so that the upper surface and both side portions of the filter on which the photocatalyst has been applied can be widely irradiated. In addition, while broadening the irradiation surface of ultraviolet rays, the venturi effect by the small diameter vent increases the pressure of the air passing through the filter on which the photocatalyst has been applied to increase the contact efficiency to the filter and enhance the deodorizing effect. Further, a small space is formed between the outer wall surface of the ventilation portion narrowed to the small diameter and the inner wall surface of the casing so that parts of the deodorizer can be disposed in the space portion, thereby reducing the size of the deodorizer. It relates to deodorizers.

従来、図４に示すように、光触媒が施されたフィルター、ファン、紫外線ＬＥＤ、エアガイド（反応容器）を備えた小型脱臭器は広く市販されており周知の技術となっている。また、小型脱臭器に関する先行技術につき、過去の特許文献を遡及検索したところ、下記の特許文献に示す「小型脱臭装置」が公知である。 Conventionally, as shown in FIG. 4, small deodorizers equipped with a photocatalyzed filter, a fan, an ultraviolet LED, and an air guide (reaction vessel) have been widely marketed and are well-known techniques. Further, as a result of a retrospective search for past patent documents regarding the prior art related to a small deodorizer, a “small deodorizer” shown in the following patent documents is known.

特開２０１３‐２０２２３２号公報JP 2013-202232 A

前記一般に市販されている小型脱臭器は、図４に示すような構成より成るものである。すなわち、図４は従来実用に供されている小型脱臭器の概略説明図であり、光触媒が施されたフィルター２１、ファン２２、紫外線ＬＥＤ２３ａ・２３ｂ、エアガイド（反応容器）２４を備えて形成されている。前記エアガイド２４において、前記光触媒が施されたフィルター２１を挿着する挿着部２５の上方の循環空気の通気部２６は前記挿着部２５と同径に形成され、前記エアガイド２４には、ベンチュリ効果により前記光触媒が施されたフィルター２１を通過する空気の圧力を高めてフィルターへの接触効率を高めるための小径に絞った通気部が備えられていないので、室内の脱臭効率が悪いという課題があった。 The generally commercially available small-sized deodorizer has a structure as shown in FIG. That is, FIG. 4 is a schematic explanatory view of a conventional small deodorizer that has been put to practical use, and includes a filter 21 to which a photocatalyst has been applied, a fan 22, ultraviolet LEDs 23a and 23b, and an air guide (reaction vessel) 24. ing. In the air guide 24, a circulating air ventilation portion 26 above the insertion portion 25 for inserting the filter 21 to which the photocatalyst is applied is formed to have the same diameter as the insertion portion 25. The ventilator is not equipped with a small-diameter vent for increasing the pressure of the air passing through the filter 21 to which the photocatalyst has been applied due to the venturi effect, thereby increasing the contact efficiency with the filter. There was a problem.

また、前記一般に市販されている小型脱臭器のエアガイド２４は、前記したようにベンチュリ効果により光触媒が施されたフィルター２１を通過する空気の圧力を高めてフィルターへの接触効率を高めるための小径に絞った通気部を備えておらず、そのため該通気部の外側壁面とケーシング２７の内側壁面間に広い空間部が形成できないので、脱臭器の部品２８を配設するスペースが確保できず、脱臭器を小型化できないという課題があった。なお、図３において、２９はファン設置部、３０は基板である。 In addition, the air guide 24 of the small deodorizer that is generally commercially available has a small diameter for increasing the contact efficiency to the filter by increasing the pressure of the air passing through the filter 21 to which the photocatalyst has been applied due to the venturi effect as described above. Therefore, a wide space cannot be formed between the outer wall surface of the ventilation portion and the inner wall surface of the casing 27. Therefore, a space for disposing the deodorizer component 28 cannot be secured, and deodorization is not possible. There was a problem that the device could not be miniaturized. In FIG. 3, 29 is a fan installation part, and 30 is a substrate.

更に、前記一般に市販されている小型脱臭器においては、光触媒が施されたフィルター２１への紫外線照射は、紫外線ＬＥＤ２３ａ・２３ｂを前記光触媒が施されたフィルター２１の面に対して横方向から照射するという構成であり、紫外線ＬＥＤ２３ａ・２３ｂを前記挿着部２５の上方に斜めに取付けるという構成が存在しないため、前記光触媒が施されたフィルター２１の上面部もしくは下面部への照射ができず、紫外線照射面を充分確保できないので、ＬＥＤによる紫外線の照射効率が悪いという課題があった。 Furthermore, in the generally commercially available small deodorizer, the UV irradiation to the filter 21 to which the photocatalyst is applied is performed by irradiating the UV LEDs 23a and 23b from the lateral direction to the surface of the filter 21 to which the photocatalyst has been applied. Since there is no configuration in which the ultraviolet LEDs 23a and 23b are obliquely mounted above the insertion portion 25, the upper surface portion or the lower surface portion of the filter 21 to which the photocatalyst is applied cannot be irradiated. Since a sufficient irradiation surface cannot be secured, there is a problem that the irradiation efficiency of ultraviolet rays by the LED is poor.

また、前記特許文献記載の「小型脱臭装置」のエアガイドは、前記したようにベンチュリ効果により光触媒が施されたフィルターを通過する空気の圧力を高めてフィルターへの接触効率を高めるための小径に絞った通気部を備えておらず、そのため該通気部の外側壁面とケーシングの内側壁面間に広い空間部が形成できないので、脱臭器の部品を配設するスペースが確保できず、脱臭器を小型化できないという課題があった。 In addition, the air guide of the “small deodorization device” described in the patent document has a small diameter for increasing the contact efficiency to the filter by increasing the pressure of the air passing through the filter on which the photocatalyst has been applied due to the venturi effect as described above. Since there is no constricted ventilation part, a wide space cannot be formed between the outer wall surface of the ventilation part and the inner wall surface of the casing. Therefore, a space for arranging the parts of the deodorizer cannot be secured, and the deodorizer is small. There was a problem that could not be realized.

更に、前記特許文献記載の「小型脱臭装置」においては、光触媒が施されたフィルターへの紫外線照射面を確保するため、紫外線ＬＥＤを前記光触媒が施されたフィルターの面に対して斜めに取付けるという構成が存在しないため、前記光触媒が施されたフィルターへの紫外線照射面を充分確保できないので、ＬＥＤによる紫外線の照射効率が悪いという課題があった。 Furthermore, in the “small deodorization apparatus” described in the above-mentioned patent document, in order to secure the ultraviolet irradiation surface to the filter on which the photocatalyst is applied, the ultraviolet LED is attached obliquely to the surface of the filter on which the photocatalyst is applied. Since there is no configuration, it is not possible to secure a sufficient ultraviolet irradiation surface to the filter on which the photocatalyst has been applied, so that there is a problem that the ultraviolet irradiation efficiency by the LED is poor.

本発明は、前記課題を解決すべくなされたもので、上・下端を開口した長方形状筒体より成るエアガイドの下方側に、光触媒が施されたフィルターを挿着する挿着部を設けると共に、該挿着部の上方側を小径に絞って小径の脱臭された空気の通気部を連設して形成する一方、前記通気部の下流側にファンを設置するか、あるいは前記挿着部の上流側にファンを設置し、紫外線ＬＥＤを前記エアガイドの挿着部の両側部において、それぞれ上・下に位置をずらし、前記光触媒が施されたフィルター面に対して傾斜して取付け、紫外線ＬＥＤによる紫外線を、前記光触媒が施されたフィルターの上面部および側面部全面を照射できるように照射面を広げる一方、前記小径とした通気部によるベンチュリ効果により、該光触媒が施されたフィルターを通過する空気の圧力を高めてフィルターへの接触効率を高め、更に、前記小径に絞った通気部の外側壁面とケーシングの内側壁面間に広い空間部を形成し、該空間部に脱臭器の部品を配置するようにして、脱臭器の小型化を図るようにした小型脱臭器を提供しようとするものである。 The present invention has been made to solve the above-mentioned problems, and has an insertion portion for inserting a filter to which a photocatalyst is applied on the lower side of an air guide made of a rectangular cylindrical body having upper and lower ends opened. The upper side of the insertion part is narrowed to a small diameter and a small-diameter deodorized air ventilation part is formed continuously, while a fan is installed downstream of the ventilation part, or the insertion part A fan is installed on the upstream side, and the UV LED is mounted on the both sides of the air guide insertion part while being shifted up and down and inclined with respect to the filter surface on which the photocatalyst has been applied. The filter with the photocatalyst is expanded by the venturi effect of the small diameter vent portion while the irradiation surface is widened so that the upper surface and the entire side surface of the filter with the photocatalyst can be irradiated with the ultraviolet rays by Increases the pressure of the air passing through to increase the efficiency of contact with the filter. Further, a wide space is formed between the outer wall surface of the ventilation section and the inner wall surface of the casing, and the parts of the deodorizer are formed in the space section. Thus, the present invention is intended to provide a small deodorizer designed to reduce the size of the deodorizer.

本発明は、前記課題を解決するため、
上・下端を開口した長方形状筒体より成るエアガイドに、光触媒が施されたフィルターを挿着する挿着部を設け、且つ該挿着部の上方側を小径に絞って小径の脱臭空気の通気部を連設し、且つ該通気部の下流側、あるいは前記挿着部の上流側のいずれか一方に、ファンを設置するファン設置部が連設されて形成されると共に、紫外線ＬＥＤを前記挿着部に対して傾斜して取付け、前記通気部によるベンチュリ効果により、該光触媒が施されたフィルターを通過する空気の圧力を高めてフィルターへの接触効率を高め、脱臭効果を高めるようにしたことを特徴とする小型脱臭器が提供され、

また更に、紫外線ＬＥＤを挿着部に対して、それぞれ上・下に位置をずらし、前記光触媒が施されたフィルター面に対して傾斜して取付け、前記一方の紫外線ＬＥＤによる紫外線を、該光触媒が施されたフィルターの上面部および側面部全面を照射できるようにし、更に、他方の紫外線ＬＥＤによる紫外線を、前記光触媒が施されたフィルターの側面部全面を照射できるように照射面を広げるようにしたことを特徴とする請求項１に記載の小型脱臭器が提供される。 In order to solve the above problems, the present invention provides:

A ventilation part is continuously provided, and a fan installation part for installing a fan is provided continuously on either the downstream side of the ventilation part or the upstream side of the insertion part. Inclined and attached to the insertion part, the venturi effect by the ventilation part increases the pressure of the air passing through the filter on which the photocatalyst has been applied to increase the contact efficiency to the filter and increase the deodorizing effect. A small deodorizer characterized by that is provided,
Alternatively, a wide space portion is formed between the outer wall surface of the ventilation portion narrowed to a small diameter and the inner wall surface of the casing, and parts of the deodorizer are arranged in the space portion so that the deodorizer can be miniaturized.

前記構成より成る本発明によれば、エアガイドの通気部の形状を絞って小径に形成としたベンチュリ効果により、循環空気が、光触媒が施されたフィルターに対しては減速・圧力高の状態で、フィルタリング効果を高め、室内の脱臭効果を高めることができる。更に、本発明小型脱臭器は、光触媒が施されたフィルターへの紫外線照射面を確保しつつ、製品を小型化するため、空間部において、紫外線ＬＥＤを前記光触媒が施されたフィルターの面に対して傾斜して取付けることで、製品の小型化が可能となった。 According to the present invention having the above-described configuration, the circulating air is in a state of reduced speed and high pressure with respect to the filter on which the photocatalyst has been applied due to the venturi effect in which the shape of the ventilation portion of the air guide is reduced to a small diameter. , The filtering effect can be enhanced and the indoor deodorizing effect can be enhanced.

本発明は、従来一般に広く実用に供されている小型脱臭器と同様に、光触媒が施されたフィルター１、ファン２、紫外線ＬＥＤ３ａ・３ｂおよびエアガイド（反応容器）４を備えて形成されている。本発明で使用する光触媒が施されたフィルター１は、特に限定する必要はないが、既に広く実用に供されている、例えば、酸化チタンを担持したセラミックフィルターを使用し、該光触媒が施されたフィルター１に紫外線ＬＥＤ３ａ・３ｂによる紫外線を照射することによって起こる酸化・還元反応を利用して室内等の悪臭を脱臭するものである。 The present invention is formed by including a filter 1, a fan 2, UV LEDs 3a and 3b, and an air guide (reaction vessel) 4 to which a photocatalyst is applied, in the same manner as a small deodorizer that has been widely used in general. . The filter 1 to which the photocatalyst used in the present invention is applied is not particularly limited, but has already been widely used in practice, for example, a ceramic filter supporting titanium oxide is used, and the photocatalyst is applied. A bad smell in the room or the like is deodorized using an oxidation / reduction reaction caused by irradiating the filter 1 with ultraviolet rays from the ultraviolet LEDs 3a and 3b.

本発明においては、光触媒が施されたフィルター１を挿着するエアガイド４の構成が、第１の実施例と第２の実施例ではそれぞれ異なる。以下、第１の実施例と第２の実施例に分けて、図面に基づいて詳細に説明する。 In this invention, the structure of the air guide 4 which inserts the filter 1 to which the photocatalyst was given differs in a 1st Example and a 2nd Example, respectively. The first embodiment and the second embodiment will be described below in detail with reference to the drawings.

先ず、第１の実施例におけるエアガイド４は、図１に示すように、上・下端に開口部５・６を備えた長方形状筒体により形成され、且つ該エアガイド４には、前記光触媒が施されたフィルター１を挿着する挿着部７が形成されると共に、該挿着部７の上方側には、その外径を絞って小径とした通気部８を連設して、前記通気部８の外側壁面とケーシング９の内側壁面間に広い空間部１０が形成され、更に、前記通気部８の下流側にはファン２を設置するファン設置部１１が連設されて形成されている。 First, as shown in FIG. 1, the air guide 4 in the first embodiment is formed by a rectangular cylinder having openings 5 and 6 at the upper and lower ends, and the air guide 4 includes the photocatalyst. An insertion portion 7 for inserting the filter 1 is formed, and an upper portion of the insertion portion 7 is continuously provided with a ventilation portion 8 having a reduced outer diameter and a small diameter. A wide space portion 10 is formed between the outer wall surface of the ventilation portion 8 and the inner wall surface of the casing 9, and a fan installation portion 11 for installing the fan 2 is connected to the downstream side of the ventilation portion 8. Yes.

そして、前記紫外線ＬＥＤ３ａ・３ｂを、前記エアガイド４の空間部１０の前記挿着部７の両側上方位置において、前記ケーシング９の内側壁面に設けられた各基板１２に、それぞれ上・下に位置をずらして、前記光触媒が施されたフィルター１の面に対して傾斜して取付け、前記一方の紫外線ＬＥＤ３ａによる紫外線を、該光触媒が施されたフィルター１の上面部および一方側の側面部全面を照射できるようにする（図１の点線部分）と共に、他方の紫外線ＬＥＤ３ｂによる紫外線を、前記光触媒が施されたフィルター１の他方側の側面部全面を照射できるよう（図１の点線部分）にして紫外線の照射面を広げる一方、前記小径とした通気部８によるベンチュリ効果により、該光触媒が施されたフィルター1を通過する空気の圧力を高めてフィルターへの接触効率を高めて脱臭効果を高め、更に、前記空間部１０に、前記基板１２等の脱臭器の部品１３を配設できるようにして、脱臭器の小型化を図るようにしたものである。 The ultraviolet LEDs 3a and 3b are positioned above and below the respective substrates 12 provided on the inner wall surface of the casing 9 at positions above both sides of the insertion portion 7 of the space portion 10 of the air guide 4. Is shifted and inclined with respect to the surface of the filter 1 to which the photocatalyst has been applied, and the ultraviolet light from the one ultraviolet LED 3a is applied to the upper surface portion of the filter 1 to which the photocatalyst has been applied and the entire side surface portion on one side. In addition to being able to irradiate (dotted line portion in FIG. 1), ultraviolet light from the other ultraviolet LED 3b is made to be able to irradiate the entire side surface of the other side of the filter 1 to which the photocatalyst has been applied (dotted line portion in FIG. 1). While expanding the ultraviolet irradiation surface, the venturi effect of the small diameter vent 8 increases the pressure of the air passing through the filter 1 to which the photocatalyst has been applied. The deodorizer is made more compact by increasing the contact efficiency with the filter to enhance the deodorizing effect, and further allowing the parts 13 of the deodorizer such as the substrate 12 to be disposed in the space 10. It is.

次に、第２の実施例を図２に基づいて詳細に説明する。第２の実施例と第１の実施例における構成部材は同一であるので、同一符号を用いて説明する。図２に示すように、第２の実施例におけるエアガイド４は、上・下端に開口部５・６を備えた長方形状筒
体により形成され、且つ該エアガイド４には、前記光触媒が施されたフィルター１を挿着する挿着部７が形成されると共に、該挿着部７の上方側には、その外径を絞って小径とした通気部８を連設して、前記通気部８の外側壁面とケーシング９の内側壁面間に広い空間部１０が形成され、更に、前記挿着部７の上流側にはファン２を設置するファン設置部１１が連設されて形成されている。すなわち、第２の実施例と第１の実施例とは、ファン２の位置が上下を逆にして設置されている Next, a second embodiment will be described in detail with reference to FIG. Since the constituent members in the second embodiment and the first embodiment are the same, description will be made using the same reference numerals. As shown in FIG. 2, the air guide 4 in the second embodiment is formed by a rectangular tube having openings 5 and 6 at the upper and lower ends, and the photocatalyst is applied to the air guide 4. An insertion portion 7 for inserting the filter 1 is formed, and a ventilation portion 8 having a reduced outer diameter is continuously provided above the insertion portion 7 so that the ventilation portion A wide space 10 is formed between the outer wall surface 8 and the inner wall surface of the casing 9, and a fan installation portion 11 for installing the fan 2 is formed on the upstream side of the insertion portion 7. . That is, in the second embodiment and the first embodiment, the position of the fan 2 is set upside down.

そして、第２実施例において、紫外線ＬＥＤ３ａ・３ｂを、前記エアガイド４の空間部１０の前記挿着部７の両側上方位置において、前記ケーシング９の内側壁面に設けられた各基板１２に、それぞれ上・下に位置をずらして、前記光触媒が施されたフィルター１の面に対して傾斜して取付け、前記一方の紫外線ＬＥＤ３ａによる紫外線を、該光触媒が施されたフィルター１の上面部および一方側の側面部全面を照射できるようにする（図２の点線部分）と共に、他方の紫外線ＬＥＤ３ｂによる紫外線を、前記光触媒が施されたフィルター１の他方側の側面部全面を照射できるよう（図２の点線部分）にして紫外線の照射面を広げる一方、前記小径として通気部８によるベンチュリ効果により、該光触媒が施されたフィルター1を通過する空気の圧力を高めてフィルターへの接触効率を高めて脱臭効果を高め、更に、前記空間部１０に、前記基板１２等の脱臭器の部品１３を配設できるようにして、脱臭器の小型化を図るようにしたものである。 In the second embodiment, the ultraviolet LEDs 3a and 3b are respectively placed on the substrates 12 provided on the inner wall surface of the casing 9 at positions above both sides of the insertion portion 7 of the space portion 10 of the air guide 4. The upper and lower sides of the filter 1 to which the photocatalyst has been applied are applied to the surface of the filter 1 to which the photocatalyst has been applied by shifting the position upward and downward. 2 can be irradiated (dotted line portion in FIG. 2), and the other side surface of the filter 1 coated with the photocatalyst can be irradiated with ultraviolet rays from the other ultraviolet LED 3b (see FIG. 2). The air passing through the filter 1 to which the photocatalyst has been applied due to the venturi effect of the ventilation portion 8 with the small diameter while expanding the irradiation surface of the ultraviolet rays as a dotted line portion) The size of the deodorizer can be reduced by increasing the pressure of the filter to increase the efficiency of deodorization by increasing the efficiency of contact with the filter, and further allowing the parts 13 of the deodorizer such as the substrate 12 to be disposed in the space 10. It is intended to be illustrated.

前記構成より成る本発明の作用について説明する。本発明において、エアガイド４の通気部８の形状を一部絞って小径にした結果、ベンチュリ効果により、光触媒が施されたフィルター１に対して循環空気が減速・圧力高の状態で、フィルタリング効果を高めて、室内の脱臭効果を高めることができる。 The operation of the present invention having the above configuration will be described. In the present invention, as a result of partially reducing the shape of the ventilation portion 8 of the air guide 4 to a small diameter, the filtering effect can be obtained when the circulating air is decelerated and the pressure is high with respect to the filter 1 subjected to the photocatalyst due to the venturi effect. The deodorizing effect in the room can be enhanced.

また、本発明小型脱臭器は、光触媒が施されたフィルター１への紫外線照射面を確保しつつ、製品を小型化するため、空間部１０において、紫外線ＬＥＤ３ａ・３ｂを前記光触媒が施されたフィルター１の面に対して傾斜して取付けることで、空間部１０を広げ、該空間部１０に脱臭器の部品１３を配設することにより、製品の小型化およびコスト削減が可能となった。 In addition, the small deodorizer of the present invention is a filter in which the UV LEDs 3a and 3b are applied to the photocatalyst in the space 10 in order to reduce the size of the product while securing the UV irradiation surface to the filter 1 to which the photocatalyst has been applied. By mounting with an inclination with respect to the surface of 1, the space portion 10 is expanded, and the deodorizer component 13 is disposed in the space portion 10, thereby making it possible to reduce the size and cost of the product.
