Description
【０００１】
本発明は、冷却装置の運転温度を検出するための温度センサを備えた冷却装置に関する。
【０００２】
内室−温度、または蒸発器の温度のような運転温度の検出のためには、冷蔵庫、冷凍庫、又はコンビネーション装置のような冷却装置では、従来では温度依存性の抵抗器が使用されており、抵抗器はケーブルハーネスを介して冷却運転を調節するための制御回路に接続されている。
【０００３】
以前から一般的なこの技術には一連の欠点がある。一方では、感温式の抵抗器を、温度を検出したい該当部に直接的に取付ける必要がある。これに対して、温度センサにより検出された温度に基づいて冷却機械の運転を調節する制御回路は、しかしながら一般的には冷却装置の冷却されていない外側領域に設けられており、これにより、制御回路における復水形成による機能妨害が防止されるようになっている。その結果、制御回路と温度センサとの不可避な位置的隔離が、温度センサの取付けを手間のかかるものにし、ひいてはこれに応じてコストも高くなる。
【０００４】
感温式の抵抗器の測定信号を制御回路に供給するためには、配線が必要である。この配線は、電磁的な拡散による妨害に対して敏感である。さらに検出された温度が必然的に、監視したい場所の温度であるわけではなく、むしろ感温式の抵抗器で生じた温度である。そこで温度測定の歪みを防止するために、抵抗器を冷却されていない外側領域に対して十分に断熱する必要がある。
【０００５】
特に蒸発器の温度を監視するためのこのような従来の温度センサが使用される場合、このような温度センサが、通常の冷却運転時の−４０℃から霜取運転時の＋８℃まで達することのある強い温度変動にさらされ、感温式の抵抗器の断熱材の極度な機械的負荷につながり、ひいては故障を招きかねない。
【０００６】
そこで本発明の課題は、温度センサを備えた冷却装置であって、この場合に温度センサの取付けが簡単であり、電磁的な拡散に対する温度センサの測定信号の感度が低減されており、熱的な負荷による故障が排除されるものを提供することである。
【０００７】
本発明の課題は請求項１に記載の冷却装置により解決される。
【０００８】
この冷却装置の赤外線センサにより検出したい運転温度は、冷却装置の内室温度であってよい。この場合、冷却装置の内室に黒体が設けられていて、赤外線センサはこの黒体と視野コンタクト（ｂｌｉｃｋｋｏｎｔａｋｔ）している。
【０００９】
測定したい運転温度として、冷却装置の蒸発器の温度も考えられる。この場合、赤外線センサは有利には、蒸発器の、冷却装置の内室に向いている方の表面と視野コンタクトしている。これにより、感温式の抵抗器による測定時ではより簡単に得ることができるが、場合によっては外部からの熱流入によって測定歪みが生じる後壁の温度の代わりに、蒸発器の内室冷却に関連する表面の温度を直接的に測定することが可能となる。赤外線センサは温度を測定したい物体と直接的に接触して配置されている必要がないため、赤外線センサを制御回路に対して直接的に隣接して、特に制御回路と共通の基板上に配置することが可能である。従って、制御回路と温度センサとは１つの構成ユニットとして前もって製造され、組立時に本発明による装置内に共に組み付けられてよい。
【００１０】
赤外線センサの温度は測定結果にとって決定的なものではないため、冷却装置の冷却されていない外側領域に取り付けられていてよい。この場合、赤外線センサは監視したい測定面から赤外線透過性の窓により隔離されていることが望ましい。この窓は、冷却装置の内室への妨げられない熱流入を遮断する。
【００１１】
赤外線センサと、赤外線センサによって監視したい測定面との間の距離が大きい場合、両者の間に、センサの放射感応性の表面に測定面を映し出すためのレンズを設けることが望ましい。このレンズは特に、既に述べた窓を同時に形成している。
【００１２】
次に、本発明の別の特徴及び利点を図示の実施例に基づき説明する。
【００１３】
図１は、本発明による冷却装置のケーシングの上方前部角隅の概略断面図を示している。冷却装置は熱絶縁されたケーシングを有しており、図１にはこのケーシングの上側１及びフロント側２の一部が、フロント側に取り付けられたドア３と共に示されている。
【００１４】
ドア３の上方のフロント側２にはカバー４が取り付けられており、このカバー４は、重要な特有の熱絶縁作用を有していない単純なプラスチック−成形部品であってよい。
【００１５】
カバー４及びフロント側２により取り囲まれている室内の基板５上には、制御回路が設けられており、この制御回路の、冷却装置の内室６に向いている方の表面には、赤外線センサ７が取り付けられている。このような赤外線センサは、赤外線放射の強度を種々様々なスペクトル範囲において検出し、強度分布に基づいて放射源の温度を推測することができる。このような赤外線センサは、例えば体温測定のためのいわゆる「耳体温計」に使用されるものと類似型のものであってよい。確かに冷却装置の内部からの赤外線放射は、人体の赤外線放射よりも明らかに弱く、概して単調であるが、冷却装置を調節する際の測定精度の要求は、体温測定の場合よりも明らかに低いため、この形の赤外線センサは冷却装置の調節のためにも適していると判断される。
【００１６】
制御回路を備えた基板５を冷却装置のフロント領域に取り付けることは、次のような利点をもたらす。すなわち、カバー４の窓９を介して使用者に見えるようになっている、発光ダイオード８のような表示エレメントを基板５に取り付けることが可能であり、これにより使用者は、冷却装置が規則通りに機能していることを随時簡単に確認することができる。例えば内室の目標温度を調節するための調節器も、同じように基板５に直接的に取り付けることができ、しかも使用者にとって良好にアクセス可能である。
【００１７】
赤外線センサ７は、フロント側２に嵌め込まれた、赤外線透過性の材料からなる窓１０に向かい合って位置しており、この窓を介して、内室６に取り付けられた黒体１１の特徴的な熱放射は、ほぼ妨害されずに赤外線センサ７の放射感応性の表面に当たることができる。
【００１８】
この黒体１１によって、内室６の臨界領域の温度を意図的に測定することが可能である。図において黒体１１が示されている、内室６のちょうど上方前部の領域がそのような領域である。なぜなら、ドア３の縁部に沿って最も強くなる内室６への熱流入によって、一般に内室の最高温度が生ぜしめられるからである。
【００１９】
しかしながら、黒体１１を省略することもことも可能であり、これにより、赤外線センサ７は窓１０を介して、ある程度、内室６への「自由な視野」を得る。この内室６は熱のバランスにおいて、同様に黒体の放射特性を有している。従って、黒体１１を取り除いた場合にも、赤外線センサ７によって赤外線センサ７の全視野にわたって平均化された温度が測定できる。このような構成では、赤外線センサの視野に、直前にはじめて冷却装置内に載せられた冷却物が存在し、そしてこの冷却物の内部温度がまだ検出されていない場合、赤外線センサ７により検出される測定値が「歪む」ことがあり得るという特殊性が生じる。物体の赤外線放射出力は、すなわち温度に伴って線形よりも著しく速く上昇する。それ故、このような「熱い」冷却物は、冷たい周囲よりもある程度「強く放射」し得る。赤外線センサにより検出された温度はこのような場合、「熱い」冷却物を考慮して形成された、計算による温度平均値よりも高い。このような測定歪みは、しかしここでは全く望ましいものである。なぜならこのような測定歪みは、新たな冷却物によってもたらされた熱が内室に広がる前に、冷却装置の冷却出力を高く調節することを可能にするからである。このようにして内室の温度上昇は、新たに持ち込まれた比較的熱い冷却物によって確実に妨げられ、このために何らかの費用のかかる回路技術的な手段を必要とせずに済む。
【００２０】
図２は、本発明による冷却装置の別の実施態様の、図１に類似した断面図である。冷却装置の既に図１に示し説明したエレメントに対して付加的に、図２には冷却装置のケーシングの後壁１３の一部、及びこれに配置された蒸発器プレート１４も示されている。この実施態様では窓１０が、窓１０と同じ材料から成るレンズ１５によって代用されている。このレンズ１５は同じようにケーシングのフロント側２に嵌め込まれていてよい。
【００２１】
レンズ１５は、図２において破線により限定されたレンズの視野１６が、図１の構成と比較して制限されており、蒸発器プレート１４の限定された領域のみを検出するという効果をもたらす。このような構成により、内室６を横切って蒸発器プレート１４の温度を精確に監視することが可能となる。
【００２２】
赤外線センサ７自体は蒸発器プレート１４で温度変動にさらされるわけではないので、赤外線センサ７の耐用寿命が温度変動によって損なわれることはなく、冷却装置の運転時の故障が妨げられる。
【００２３】
既に述べた実施例の種々様々な別の実施態様が本発明の枠内で可能である。例えば複数の赤外線センサを基板５に取付け、これらの赤外線センサがそれぞれ１つの専用の窓を介して、冷却装置の内室６内の１つの視野を監視するということも考えられる。このような異なる温度監視は、制御回路が、例えば局所的にのみ上昇させられた温度測定値を生ぜしめる新たに持ち込まれた冷却物と、冷却の停止により全内室６の温度が上昇するという一般的な機能故障とを区別することを可能にする。

The present invention relates to a cooling device provided with a temperature sensor for detecting an operating temperature of the cooling device.
[0002]
For the detection of the operating temperature, such as the interior chamber temperature, or the temperature of the evaporator, temperature-dependent resistors are conventionally used in refrigerators, freezers, or cooling devices such as combination devices, The resistor is connected via a cable harness to a control circuit for regulating the cooling operation.
[0003]
This technique, which has long been common, has a series of disadvantages. On the one hand, it is necessary to mount a temperature-sensitive resistor directly on the part where the temperature is to be detected. In contrast, a control circuit that regulates the operation of the cooling machine based on the temperature detected by the temperature sensor, however, is typically provided in the uncooled outer region of the cooling device, thereby providing control. Functional disturbance due to condensate formation in the circuit is prevented. As a result, the unavoidable positional separation between the control circuit and the temperature sensor makes the mounting of the temperature sensor cumbersome and therefore correspondingly expensive.
[0004]
Wiring is necessary to supply the measurement signal of the temperature-sensitive resistor to the control circuit. This wiring is sensitive to disturbances due to electromagnetic diffusion. Furthermore, the detected temperature is not necessarily the temperature of the location to be monitored, but rather the temperature generated by the temperature-sensitive resistor. Thus, in order to prevent distortion in the temperature measurement, the resistor must be sufficiently insulated from the uncooled outer region.
[0005]
Especially when such a conventional temperature sensor for monitoring the temperature of the evaporator is used, such a temperature sensor can reach from -40 ° C during normal cooling operation to + 8 ° C during defrosting operation. Exposure to extreme temperature fluctuations can lead to extreme mechanical loading of the thermal insulation of the temperature sensitive resistor, which can lead to failure.
[0006]
Therefore, an object of the present invention is to provide a cooling device having a temperature sensor, in which the temperature sensor is easily mounted, the sensitivity of the measurement signal of the temperature sensor to electromagnetic diffusion is reduced, It is to provide a system in which a failure due to a heavy load is eliminated.
[0007]
The object of the invention is achieved by a cooling device according to claim 1.
[0008]
The operating temperature desired to be detected by the infrared sensor of the cooling device may be the inner room temperature of the cooling device. In this case, a black body is provided in the inner chamber of the cooling device, and the infrared sensor is in visual contact with the black body.
[0009]
As the operating temperature to be measured, the temperature of the evaporator of the cooling device can be considered. In this case, the infrared sensor is advantageously in field contact with the surface of the evaporator facing the interior of the cooling device. This can be obtained more easily when measuring with a temperature-sensitive resistor, but in some cases, instead of using the temperature of the rear wall, which causes measurement distortion due to heat inflow from the outside, it can be used to cool the inner chamber of the evaporator. The temperature of the relevant surface can be measured directly. Since the infrared sensor does not need to be placed in direct contact with the object whose temperature is to be measured, the infrared sensor is placed directly adjacent to the control circuit, particularly on a common substrate with the control circuit. It is possible. Thus, the control circuit and the temperature sensor may be manufactured in advance as one component unit and assembled together in the device according to the invention during assembly.
[0010]
Since the temperature of the infrared sensor is not critical for the measurement result, it may be mounted in the uncooled outer region of the cooling device. In this case, it is desirable that the infrared sensor be separated from the measurement surface to be monitored by a window that transmits infrared light. This window blocks unobstructed heat flow into the interior of the cooling device.
[0011]
If the distance between the infrared sensor and the measuring surface to be monitored by the infrared sensor is large, it is desirable to provide a lens between them to project the measuring surface on the radiation-sensitive surface of the sensor. In particular, this lens simultaneously forms the window already described.
[0012]
Next, other features and advantages of the present invention will be described based on the illustrated embodiment.
[0013]
FIG. 1 shows a schematic sectional view of the upper front corner of the casing of the cooling device according to the invention. The cooling device has a heat-insulated casing, and FIG. 1 shows the upper part 1 and part of the front side 2 of the casing with a door 3 mounted on the front side.
[0014]
Mounted on the front side 2 above the door 3 is a cover 4, which may be a simple plastic-molded part without any significant specific thermal insulation.
[0015]
A control circuit is provided on a substrate 5 in a room surrounded by the cover 4 and the front side 2, and an infrared sensor is provided on a surface of the control circuit facing the inner room 6 of the cooling device. 7 is attached. Such infrared sensors can detect the intensity of infrared radiation in a variety of different spectral ranges and can estimate the temperature of the radiation source based on the intensity distribution. Such an infrared sensor may for example be of a type similar to that used in so-called "ear thermometers" for measuring body temperature. Certainly, infrared radiation from the inside of the cooling device is clearly weaker than the human body's infrared radiation and is generally monotonous, but the requirements for measurement accuracy when adjusting the cooling device are clearly lower than in the case of body temperature measurement Therefore, it is determined that this type of infrared sensor is also suitable for adjusting the cooling device.
[0016]
Mounting the substrate 5 with the control circuit in the front area of the cooling device has the following advantages. That is, it is possible to attach a display element, such as a light-emitting diode 8, which is visible to the user via the window 9 of the cover 4, to the substrate 5, so that the cooling device can be arranged in a regular manner. Can be easily checked at any time. For example, an adjuster for adjusting the target temperature of the inner chamber can likewise be mounted directly on the substrate 5 and is well accessible to the user.
[0017]
The infrared sensor 7 is located opposite a window 10 made of an infrared-transmissive material and fitted on the front side 2, through which the characteristic of the black body 11 attached to the inner chamber 6. Thermal radiation can impinge on the radiation-sensitive surface of the infrared sensor 7 almost undisturbed.
[0018]
The black body 11 allows the temperature in the critical region of the inner chamber 6 to be measured intentionally. The region just above the front of the inner chamber 6, in which the black body 11 is shown in the figure, is such a region. This is because the heat flow into the inner chamber 6, which is strongest along the edge of the door 3, generally produces the highest temperature in the inner chamber.
[0019]
However, it is also possible to omit the black body 11, whereby the infrared sensor 7 obtains a certain “free view” of the interior 6 through the window 10. This inner chamber 6 also has the radiation characteristics of a black body in terms of heat balance. Therefore, even when the black body 11 is removed, the temperature averaged over the entire field of view of the infrared sensor 7 can be measured by the infrared sensor 7. In such a configuration, a cooling object placed in the cooling device for the first time immediately before exists in the field of view of the infrared sensor, and if the internal temperature of the cooling object has not been detected yet, the cooling object is detected by the infrared sensor 7. A specialty arises in that the measurements can be "distorted". The infrared radiation output of an object increases with temperature, i.e. significantly faster than linearly. Thus, such "hot" coolant may radiate to some extent "stronger" than its cold surroundings. The temperature detected by the infrared sensor is in such a case higher than the calculated temperature average, which takes into account the "hot" coolant. Such measurement distortions, however, are quite desirable here. This is because such measurement distortions allow the cooling output of the cooling device to be adjusted higher before the heat provided by the new coolant spreads into the interior chamber. In this way, an increase in the temperature of the interior chamber is reliably prevented by the newly brought in relatively hot coolant, so that no expensive circuit engineering measures are required.
[0020]
FIG. 2 is a sectional view similar to FIG. 1 of another embodiment of the cooling device according to the invention. In addition to the elements already shown and described in FIG. 1 of the cooling device, FIG. 2 also shows a part of the rear wall 13 of the housing of the cooling device and the evaporator plate 14 arranged thereon. In this embodiment, the window 10 is replaced by a lens 15 made of the same material as the window 10. This lens 15 can likewise be fitted on the front side 2 of the casing.
[0021]
Lens 15 has the effect that the field of view 16 of the lens defined by the dashed line in FIG. 2 is limited compared to the configuration of FIG. 1 and only the limited area of evaporator plate 14 is detected. With such a configuration, it is possible to accurately monitor the temperature of the evaporator plate 14 across the inner chamber 6.
[0022]
Since the infrared sensor 7 itself is not exposed to temperature fluctuations at the evaporator plate 14, the useful life of the infrared sensor 7 is not impaired by the temperature fluctuations, and a failure during operation of the cooling device is prevented.
[0023]
A variety of alternative embodiments of the embodiments already described are possible within the framework of the invention. For example, it is conceivable that a plurality of infrared sensors are mounted on the substrate 5 and each of these infrared sensors monitors one field of view in the inner chamber 6 of the cooling device via one dedicated window. Such a different temperature monitoring is such that the control circuit may, for example, increase the temperature of the entire inner chamber 6 due to the newly introduced coolant, which results in a temperature measurement that is only increased locally, and the cessation of cooling. It is possible to distinguish from general functional failures.
