Description

本発明は電気ヒ−タ−を使用して暖房を行う温風暖房機に関するものである。   The present invention relates to a hot air heater that performs heating using an electric heater.

従来のこの種の温風暖房機は、例えば電気ヒ−タ−に送風機から送風して熱交換させ温風を生み出し室内を暖房するもの（特許文献１参照）がある。   Conventional hot air heaters of this type include, for example, an electric heater that blows air from a blower to exchange heat to generate hot air to heat the room (see Patent Document 1).

図４は、特許文献１に記載された従来の、温風暖房機を示すものである。図４に示すように、５１は通電により発熱するヒータ−で、５２は送風機、５３は吸気口、５４は吹出口、５５は操作部、５６はリアケ−ス、５７はフロントケ−スである。
この構成でヒータ−５１と送風機５２に通電すると、送風機５２は所定の回転数で回転して吸気口５３から室内の空気を吸い込み、発熱したヒ−タ−５１に送風する。この空気はヒ−タ−５１を通過する際に熱交換して温風となり、吹出口５４から吹き出され、室内を暖房することが出来るものである。
特開２００３−１０６５７８号公報 FIG. 4 shows a conventional hot air heater described in Patent Document 1. As shown in FIG. As shown in FIG. 4, 51 is a heater that generates heat when energized, 52 is a blower, 53 is an air inlet, 54 is an air outlet, 55 is an operation unit, 56 is a rear case, and 57 is a front case.

JP 2003-106578 A

しかしながら前記これら従来の構成では、以下の課題を有している。
１．この種の温風暖房機は、デザイン性を高めるために外郭部品に樹脂を使用することが多く、リアケ−スに内部構造物の取付けボスやリブ、送風機のファンケ−ス形状などを構成しなくてはならないため、本体背面に多くのヒケが生じ外観を損なう。 However, these conventional configurations have the following problems.
1. This type of hot air heater often uses resin for the outer parts to enhance the design, and the rear case does not constitute mounting bosses and ribs of internal structures, fan case shape of the blower, etc. Doing so will cause many sink marks on the back of the main unit, resulting in a loss of appearance.

特に、この種の温風暖房機では異常時を想定しある程度の耐熱は必要なため外観材料に耐熱温度が比較的高く安価なＰＰを使用するケ−スが多く、ＰＰの特性からさらにヒケが生じやすい。
２．ヒケが生じやすいためにその対策のひとつとして外郭表面にシボ加工を入れて光沢を消し、ヒケが目立ちにくいようにすることが一般的に行われるが、樹脂材料は静電気でホコリを呼びやすく、付着したホコリがシボ加工の中に入ってとれにくくなる。 In particular, this type of hot air heater requires a certain degree of heat resistance in the event of an abnormality, so there are many cases in which PP having a relatively high heat resistance temperature and a low price is used for the appearance material. Prone to occur.
2. In order to prevent the occurrence of sink marks, it is common to make the outer surface of the outer surface glossy by removing the gloss to make the sink marks less noticeable. However, the resin material is easy to call for dust due to static electricity. Dust is difficult to get into the graining process.

本発明は前記従来の課題を解決するもので、温風暖房機の構成にセンタ−ケ−スを加えこれにファンケ−ス部の形状を備えるとともに内部構造物の取り付け構造を持たせることで、外郭部品であるリアケ−スに設けるボスやリブを大幅に削減できるので、本体背面にヒケを生じることがなく、外観品位を向上できる。またヒケがわずかであるためシボの有無は自由に選択することができるためデザイン的な選択の自由度が広げることを実現した温風暖房機を提供することを目的としている。   The present invention solves the above-mentioned conventional problems, by adding a center case to the structure of the hot air heater and providing a fan case part shape to this, and having an attachment structure for an internal structure, Since the bosses and ribs provided on the rear case, which is the outer part, can be greatly reduced, the appearance quality can be improved without causing sink marks on the back surface of the main body. In addition, since there are few sink marks, it is possible to freely select the presence or absence of grain, and the object is to provide a hot air heater that realizes a wider design freedom.

前記従来の課題を解決するために、本発明の温風暖房機は、ヒ−タ−と、ヒータ−を内包し風路を形成するダクトと、このダクトに室内空気を送風する送風機を備え、前記送風機の上流側は本体外郭の背面を形成するリアケ−スの一部に設けた開口部に連通し、前記リアケ−スの開口部にフィルタ−を備えたフィルタ−カバ−を設けるとともに、前記ダクトの下流側は本体外郭の正面を形成するフロントケ−スに設けた吹出口に連通させ、本体外郭の一部に設けた操作部と前記ヒ−タ−と送風機を運転制御する制御基板を備え、前記フロントケ−スとリアケ−スの間にセンタ−ケ−スを配設するとともに、前記このセンタ−ケ−スに送風機のファンケ−ス部の形状を備え、かつ、送風機、ダクト、制御基板の取り付け構造を備えたことを特長として構成したものである。これによって、樹脂で構成さ
れる本体外観に生じるヒケをほとんど発生しないようにして外観品位を向上させるとともに、外郭にヒケ対策のひとつとして入れるシボ加工の必要性がなくなり、表面仕上がりの選択の自由度を広げることができ、デザイン性の高い温風暖房機を提供することができる。 In order to solve the above-described conventional problems, a warm air heater of the present invention includes a heater, a duct that includes a heater and forms an air passage, and a blower that blows indoor air to the duct. The upstream side of the blower communicates with an opening provided in a part of the rear case forming the back surface of the outer shell of the main body, and a filter cover including a filter is provided in the opening of the rear case, and The downstream side of the duct communicates with an air outlet provided in a front case that forms the front of the main body outer shell, and includes an operation section provided in a part of the main body outer shell, a control board that controls the operation of the heater and the blower. A center case is disposed between the front case and the rear case, and the center case has a shape of a fan case part of a blower, and a blower, a duct, and a control board Features a mounting structure To those that you configured. As a result, the appearance quality is improved by generating almost no sink marks on the exterior of the main body made of resin, and there is no need for embossing as one of the countermeasures for sink marks in the outer shell. And a hot air heater with high design can be provided.

本発明の温風暖房機は、樹脂で構成される本体外観に生じるヒケをほとんど発生しないようにして外観品位を向上させるとともに、外郭にヒケ対策のひとつとして入れるシボ加工の必要性がなくなり、表面仕上がりの選択の自由度を広げることができ、デザイン性の高い温風暖房機を提供することができる。   The hot air heater of the present invention improves the appearance quality so as to hardly cause sink marks occurring on the exterior of the main body made of resin, and eliminates the need for embossing to be put into the outer shell as one of the measures against sink marks. The degree of freedom in selecting the finish can be expanded, and a hot air heater with high design can be provided.

第１の発明は、ヒ−タ−と、ヒータ−を内包し風路を形成するダクトと、このダクトに室内空気を送風する送風機を備え、前記送風機の上流側は本体外郭の背面を形成するリアケ−スの一部に設けた開口部に連通し、前記リアケ−スの開口部にフィルタ−を備えたフィルタ−カバ−を設けるとともに、前記ダクトの下流側は本体外郭の正面を形成するフロントケ−スに設けた吹出口に連通させ、本体外郭の一部に設けた操作部と前記ヒ−タ−と送風機を運転制御する制御基板を備え、前記フロントケ−スとリアケ−スの間にセンタ−ケ−スを配設するとともに、前記このセンタ−ケ−スに送風機のファンケ−ス部の形状を備え、かつ、送風機、ダクト、制御基板の取り付け構造を備えたことを特長として構成したものである。   A first invention includes a heater, a duct that encloses a heater and forms an air passage, and a blower that blows indoor air in the duct, and an upstream side of the blower forms a back surface of a main body outline. A front cover that communicates with an opening provided in a part of the rear case, and is provided with a filter cover including a filter in the opening of the rear case, and the downstream side of the duct forms a front surface of the outer shell of the body. An operation part provided at a part of the outer shell of the main body, a control board for controlling the operation of the heater and the blower, and a center between the front case and the rear case; -Cases are arranged, and the center case is provided with the shape of the fan case part of the blower, and the mounting structure of the blower, duct and control board is provided as a feature. It is.

そして、本体主要構造を構成する際に、フロントケ−スとリアケ−スだけではなくセンタ−ケ−スを設け、このセンタ−ケ−スにファンケ−ス部の形状を備えるとともに内部部品、たとえば送風機、制御基盤、風路などを取り付けるボスやリブを備えたことにより、特にリアケ−スにはそれらのボスやリブを設ける必要がなくなるので、本体外観に生じるヒケをほとんど発生しないようにして外観品位を向上させるとともに、外郭にヒケ対策のひとつとして入れるシボ加工の必要性がなくなり、表面仕上がりの選択の自由度を広げることができ、デザイン性の高い温風暖房機を提供することができる。
第２の発明は、特に第１の発明のセンタ−ケ−スは、室内床面に本体を安定載置するための脚部と一体構造とし、内部部品を支持するセンタ−ケ−スを本体のベ−ス部分と一体構造にしてあるので、内部部品の質量を床面との間で直接支持することができ、センタ−ケ−スの剛性を高めることができる。従ってフロントケ−ス、リアケ−スといった外観部品の構造的な負担を大幅に軽減できるため、それら外観部品に設けるリブなどの補強構造を大幅に削減でき、外観にヒケが少ないデザイン性の高い温風暖房機を提供することができる。 When the main structure of the main body is constructed, not only the front case and the rear case but also the center case is provided, and the center case is provided with the shape of the fan case part and the internal part, for example, a blower By providing bosses and ribs for mounting the control board, air passages, etc., there is no need to provide those bosses and ribs, especially in the rear case. In addition, the need for embossing as one of the measures for sink marks in the outer shell is eliminated, and the degree of freedom in selecting the surface finish can be expanded, thereby providing a hot air heater with high design.
According to the second aspect of the invention, the center case of the first aspect of the invention is particularly integrated with a leg portion for stably placing the main body on the indoor floor surface, and the center case for supporting the internal parts is the main body. Therefore, the mass of the internal parts can be directly supported between the base portion and the floor surface, and the rigidity of the center case can be increased. Therefore, the structural burden of external parts such as the front case and the rear case can be greatly reduced, and the reinforcing structure such as ribs provided on these external parts can be greatly reduced, and hot air with high design that has few appearance marks. A heater can be provided.

第３の発明は、特に第１または第２の発明の制御基板を係止する制御基板ケ−スをセンタ−ケ−スとは別部品として配置し、この制御基板ケ−スの材質を難燃グレ−ド樹脂とし、センタ−ケ−スから制御基板ケ−スを分離して、制御基板ケ−スのみを材質を難燃グレ−ドにしているので、１００Ｖ電源が印加されていて将来部品の劣化などで発火源になり得る制御基板を覆い延焼を防止するとともに、高価な難燃樹脂は制御基板ケ−スのみとしているのでコスト負担も最小限で実現できる安全な温風暖房機を提供することができる。第４の発明は、特に第１または第２の発明の制御基板を係止する制御基板ケ−スをセンタ−ケ−スとは別部品として配置し、この制御基板ケ−スの材質を板金とし、センタ−ケ−スから制御基板ケ−スを分離して、制御基板ケ−スのみを板金で構成しているので、１００Ｖ電源が印加されていて将来部品の劣化などで発火源になり得る制御基板を覆い延焼を防止するとともに、複雑な構造のセンタ−ケ−スは樹脂で構成可能なため、比較的安価に安全な温風暖房機を提供することができる。   In the third invention, the control board case for locking the control board of the first or second invention is arranged as a separate part from the center case, and the material of the control board case is difficult. Since the control board case is separated from the center case and the material of the control board case is made of flame retardant, it is made of a flame grade resin. Covering the control board, which can be a source of ignition due to deterioration of parts, prevents the spread of fire, and since the expensive flame retardant resin is only the control board case, a safe hot air heater that can be realized with minimal cost burden Can be provided. In the fourth invention, a control board case for locking the control board of the first or second invention is arranged as a separate part from the center case, and the material of the control board case is made of sheet metal. Since the control board case is separated from the center case, and only the control board case is made of sheet metal, a 100V power supply is applied and it becomes a source of ignition due to deterioration of parts in the future. The obtained control board is covered to prevent the spread of fire, and the center case having a complicated structure can be made of resin. Therefore, a safe hot air heater can be provided at a relatively low cost.

以下、本発明の実施の形態について、図面を参照しながら説明する。なお、この実施の形態によって本発明が限定されるものではない。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

（実施の形態１）
図１は、本発明の第１の実施の形態における温風暖房機の外観図、図２は構成部品の展開斜視図である。 (Embodiment 1)
FIG. 1 is an external view of a hot air heater according to a first embodiment of the present invention, and FIG. 2 is an exploded perspective view of components.

図１、図２において、１はフロントケ−ス、２はリアケ−ス、３はセンタ−ケ−スで本体のベ−ス部３ａと一体の構成としてある。４は難燃グレ−ド樹脂で成型した制御基板ケ−ス、５はトップケ−ス、６はトップケ−ス５に設けた操作部、７は本体を移動する際に持つハンドル、８はフィルタ−カバ−、９は送風機、１０はダクト、１１はヒーター、１２は吹出口、１３は温風の方向を変えるル−バ−、１４は制御基板である。また本実施例の温風暖房機は加湿機能を備えるため、その構成部品を説明すると、１５は加湿トレイ、１６は加湿トレイ１５に載置した加湿フィルタ−、１７は給水タンク、１８はタンクカバ−を設けて構成している。   1 and 2, reference numeral 1 denotes a front case, 2 denotes a rear case, and 3 denotes a center case, which is integrated with the base portion 3a of the main body. 4 is a control board case molded with flame retardant grade resin, 5 is a top case, 6 is an operation part provided on the top case 5, 7 is a handle for moving the main body, and 8 is a filter. A cover, 9 is a blower, 10 is a duct, 11 is a heater, 12 is a blower outlet, 13 is a louver that changes the direction of hot air, and 14 is a control board. Further, since the warm air heater of this embodiment has a humidifying function, its components will be described. 15 is a humidifying tray, 16 is a humidifying filter placed on the humidifying tray 15, 17 is a water supply tank, and 18 is a tank cover. Is provided.

このとき、送風機９のファンを回転させて送風するために必要なファンケ−ス形状と、制御基板ケ−ス４、送風機９、ダクト１０、およびそれらに電力供給や信号授受を行うリ−ド線（図示せず）を係止する構成はすべてセンタ−ケ−ス３に構成している。従って、リアケ−ス２にこれら複雑な形状を構成しなくて済み、それによって樹脂で構成される本体外観に生じるヒケをほとんど発生しないようにして外観品位を向上させるとともに、外郭にヒケ対策のひとつとして入れるシボ加工の必要性がなくなり、表面仕上がりの選択の自由度を広げることができる、デザイン性の高い温風暖房機を構成している。また、内部部品を支持するセンタ−ケ−ス３を本体のベ−ス部３ａと一体構造にしてあるので、内部部品の質量を床面との間で直接支持することができ、センタ−ケ−ス３の剛性を高めることができる。従ってフロントケ−ス１、リアケ−ス２といった外観部品の構造的な負担を大幅に軽減できるため、それら外観部品に設けるリブなどの補強構造を大幅に削減でき外観にヒケが少ないデザイン性の高い温風暖房機を提供することができる。
以上のように構成された温風暖房機について、以下その動作、作用を説明する。 At this time, the fan case shape necessary for rotating the fan of the blower 9 to blow the air, the control board case 4, the blower 9, the duct 10, and the lead wires for supplying power to and receiving signals from them. All the structures for locking (not shown) are configured in the center case 3. Therefore, it is not necessary to form these complicated shapes in the rear case 2, thereby improving the appearance quality so that the appearance of the main body composed of resin hardly occurs, and one of the measures for the anti-scratch on the outer shell. As a result, there is no need for embossing, and a hot air heater with high design can be constructed that can expand the degree of freedom in selecting the surface finish. Further, since the center case 3 for supporting the internal parts is integrated with the base portion 3a of the main body, the mass of the internal parts can be directly supported between the floor and the center case. -The rigidity of the sleeve 3 can be increased. Therefore, the structural burden on the external parts such as the front case 1 and the rear case 2 can be greatly reduced, so that the reinforcing structure such as the ribs provided on the external parts can be greatly reduced, and the appearance of the design is low. A wind heater can be provided.
About the warm air heater comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

まず、本体を水平な場所に置き、タンクカバ−１８をあけて給水タンク１７を取り出して給水したあと、再び給水タンク１７を本体にセットしてタンクカバ−１８を締めると給水タンク１７内の水が加湿トレイ１５に流出して溜まり、その水が定水面に達するまで待ってから電源プラグ（図示せず）を家庭のコンセント（図示せず）に差込み、操作部６の運転スイッチを押す。すると送風機９が回転して送風を始めるとともにヒ−タ−１１に通電を始めるため、室内空気は吸気口にあるフィルタ−カバ−８から本体内に吸気されダクト１０内で発熱したヒ−タ−１１と熱交換されて温風となり、水を溜めた加湿トレイ１５内に載置し水を十分に給水した加湿フィルタ−１６の水面からの露出部分に接触しながら吹出口１２から室内へ吹き出され、乾燥感のない温風暖房を実現できる。   First, place the main body on a horizontal surface, open the tank cover 18 and take out the water supply tank 17 to supply water, then set the water supply tank 17 on the main body again and tighten the tank cover 18 to humidify the water in the water supply tank 17. After flowing out and collecting in the tray 15 and waiting for the water to reach a constant water surface, a power plug (not shown) is inserted into a household outlet (not shown), and the operation switch of the operation unit 6 is pushed. Then, since the blower 9 rotates to start blowing air and the heater 11 starts to energize, the indoor air is sucked into the main body from the filter cover 8 at the intake port and heat is generated in the duct 10. The heat is exchanged with the heat source 11 to become hot air, which is placed in the humidifying tray 15 in which water is stored and blown into the room from the air outlet 12 while being in contact with the exposed portion of the humidifying filter 16 that has sufficiently supplied water. It can realize warm air heating without dryness.

このように、高機能でかつ、デザイン性の高い温風暖房機を提供することができる。   In this way, it is possible to provide a hot air heater with high functionality and high design.

（実施の形態２）
図３は本発明の実施の形態２における温風暖房機の構成部品の展開斜視図である。なお、本実施の形態は、実施の形態１における温風暖房機の構成部品の材質構成が実施の形態１の発明と異なるだけで、同一の番号を付与し、異なる構成についてのみ説明を行う。 (Embodiment 2)
FIG. 3 is an exploded perspective view of components of the hot air heater according to Embodiment 2 of the present invention. In the present embodiment, only the material configuration of the components of the hot air heater in the first embodiment is different from that of the first embodiment, and the same reference numerals are given, and only different configurations will be described.

図３において、実施の形態１と異なる部分のみ説明すると、制御基板１４を収める制御基板ケ−ス２０はセンタ−ケ−ス３から分離され、板金で構成してある。   In FIG. 3, only the parts different from the first embodiment will be described. The control board case 20 for accommodating the control board 14 is separated from the center case 3 and is made of sheet metal.

以上のように構成された温風暖房機について、以下その動作、作用を実施の形態１と異なる部分のみ説明する。   About the warm air heater comprised as mentioned above, the operation | movement and effect | action are demonstrated below only about the part different from Embodiment 1. FIG.

制御基板１４を収める制御基板ケ−ス２０は、センタ−ケ−ス３から分離して不燃材である板金で構成してあるので、経年的に部品が劣化して、１００Ｖ電源が印加してある制御基板１４が万一発火しても他の部位への延焼を確実に防止できる安全性の高い温風暖房機を提供することができる。   Since the control board case 20 for accommodating the control board 14 is made of sheet metal which is a non-combustible material separated from the center case 3, the parts deteriorate over time, and a 100V power supply is applied. Even if a certain control board 14 is ignited, it is possible to provide a hot air heater with high safety that can surely prevent the spread of fire to other parts.

なお、本実施例では加湿機能を持つ温風機を示したが、それに限定されるものではなく、たとえば温風機能のみのタイプでも同様の構成が可能で、十分な効果がある。   In this embodiment, a warm air fan having a humidifying function is shown. However, the present invention is not limited to this. For example, a similar structure can be achieved with a type having only a warm air function, and there is a sufficient effect.

また、本発明の制御基板ケ−ス２０は板金で構成しているが、難燃グレ−ドの樹脂で成型しても同等の効果が得られる。   Further, although the control board case 20 of the present invention is made of sheet metal, the same effect can be obtained even if it is molded with a flame retardant grade resin.

以上のように、本発明にかかる温風暖房機は、樹脂で構成される本体外観品位を向上させるとともに、表面仕上がりの選択の自由度を広げることができる、デザイン性の高い温風暖房器具等に使用できる   As described above, the hot air heater according to the present invention improves the appearance quality of the main body made of resin, and can widen the degree of freedom in selecting the surface finish.
