Description

【0001】
【発明の属する技術分野】
この発明は、排水パイプを備える冷蔵ショーケースに関している。
また、この発明は、冷蔵ショーケースの排水パイプを洗浄する方法にも関する。
【0002】
【従来の技術】
図2に従来の冷蔵ショーケースの全体図を示す。冷蔵ショーケースには、食材を冷蔵保存しながら展示する展示スペース1と、展示スペース1を冷却するためのコンプレッサーやコンデンサ等の冷凍回路構成部品が収納されている機械室2とが互いに隣接して設けられている。展示スペース1の前部から前上部及び左側部にはそれぞれ透明なガラス板3が嵌め込まれ、ショーケースの前側からガラス板3を通して収納された食材が見えるようになっている。また、展示スペース1の後部には透明なガラス板4からなるスライド扉が設けられており、ショーケースの後側からガラス板4を通して収納された食材が見えると共にスライド扉を開けて展示スペース1内の食材の出し入れを行うように構成されている。
【0003】
図3にこの冷蔵ショーケースの断面図を示す。機械室2内の冷凍回路構成部品に接続されて冷凍回路を構成しているエバポレータ5が、展示スペース1の上部及び底面6の裏側に設けられ、スノコ7上に置かれている食材を冷却する。また、底面6は前方へ向け下方に傾斜しており、底面6の最も低い箇所である前端部に庫内排水口8が開口されている。この庫内排水口8には、ショーケースの後方に向かって下方に傾斜させた排水パイプ9が接続されており、この排水パイプ9を通して庫内からの排水を外部に排出するよう構成されている。冷蔵ショーケースの通常運転時即ち展示スペース1が冷却されている場合には、庫内排水口8には着脱可能な栓10が備えられ、展示スペース1からの冷気の漏出及び外部からの害虫の侵入を防いでいる。
【0004】
このような冷蔵ショーケースは使用に伴って展示スペース1内が汚れるため、一般に営業終了後に展示スペース1内の洗浄が行われる。洗浄時には、まず冷却運転を停止してスノコ7を取出した後、庫内排水口8を塞いでいた栓10を取り外す。その後、展示スペース1内に水を流し、洗剤を用いてスポンジ等で擦り洗いを行う。水や洗剤等の汚水及び食材の残留物等の汚物は庫内排水口8から排水パイプ9を通ってショーケースの外部へ排出される。ここで図4に示されるように、排水パイプ9の出口11には、L字管いわゆるエルボ12が接続され、さらにエルボ12に接続されている排水ホース13を介すことにより汚水及び汚物がシンク14の排水口へ導かれる。なお、シンク14がエルボ12の真下に位置する場合は、排水ホース13を用いずに、エルボ12から直接シンク14に排水される。
【0005】
このようにして展示スペース1内の洗浄が行われるが、汚水及び汚物の通過によって排水パイプ9の内部が不衛生になり易いため、排水パイプ9内を洗浄する必要がある。しかし、排水パイプ9内は細く、また、場合によっては折れ曲がっている箇所があるため、直接的に洗浄することが困難であった。そこで従来は図5に示されるように、洗浄の際には、それまで接続していたエルボ12を取り外し、代わりに排水パイプ9の出口11に軟質ゴム製の栓15をはめ込んで塞ぎ、この状態で展示スペース1内から庫内排水口8に洗浄剤を注入し、排水パイプ9内を洗浄剤で満たす。そのままの状態で一定時間放置しておき、排水パイプ9内の洗浄が完了した後、出口11の栓15を抜いて洗浄剤の排出を行う。その後、水等で排水パイプ9内を洗い流すことなく排水パイプ9内に付着した洗浄剤を乾燥させる。これは、洗浄剤の殺菌効果の減少を防ぐためである。なお、排水パイプ9は硬質樹脂から作られていることが多く、洗浄剤には次亜塩素酸ソーダの希釈液を用いるのが一般的である。
【0006】
【発明が解決しようとする課題】
しかしながら、排水パイプ9内を洗浄剤で満たす場合に、エルボ12を取り外して代わりに栓15をするという作業は、手間が掛かり、面倒な作業である。また、この栓15は常時使用するものではないために紛失し易く、紛失すると排水パイプ9内の洗浄作業が行えずに、排水パイプ9内が不衛生になるおそれがある。
また、次亜塩素酸ソーダの希釈液が洗浄剤として使われているので、庫内排水口8へ注入する際に、底面6に誤ってこぼしてしまうと、この底面6に錆を発生させる原因となる。展示スペース1の底面6の材質はステンレス製だが、洗浄剤は乾燥することにより高濃度になるため、錆の発生しにくいステンレスであっても錆を発生させることとなり、冷蔵ショーケースの製品寿命を短くしてしまうおそれがある。
【0007】
本発明は以上のような問題点を解決するためになされたもので、容易に排水パイプ内の洗浄作業を行うことができると共に製品の長寿命化を図ることができる冷蔵ショーケース及び排水パイプの洗浄方法を提供することを目的とする。
【0008】
【課題を解決するための手段】
上述の目的を達成するために、本発明に係る冷蔵ショーケースは、展示スペースの底部に開口された庫内排水口に排水パイプの一端が接続されていると共に排水パイプの他端が外部に連通している冷蔵ショーケースにおいて、排水パイプの他端に回転自在に連結されたエルボを備え、エルボはその出口端が上方を向くように回転させたときに出口端の高さが庫内排水口の高さ以上となるような寸法を有するものである。
また、本発明に係る排水パイプの洗浄方法は、冷蔵ショーケースの展示スペースの底部に開口された庫内排水口に一端が接続されると共に他端が外部に連通している排水パイプの洗浄方法において、排水パイプの他端に回転自在にエルボを連結し、エルボの出口端を上方に向けてこの出口端から排水パイプ内に洗浄剤を注入するものである。
【0009】
【発明の実施の形態】
以下、この発明の実施の形態を添付図面に基づいて説明する。
図1に本実施の形態に係る冷蔵ショーケースの断面図を示す。この実施の形態の冷蔵ショーケースは、図2に示した従来の冷蔵ショーケースにおいて、排水パイプ9内の洗浄方法を改良したものであり、図2のショーケースと同様の全体構成を有している。即ち、食材を冷蔵保存しながら展示する展示スペース1と、展示スペース1を冷却するためのコンプレッサーやコンデンサ等の冷凍回路構成部品が収納されている機械室2とが互いに隣接して設けられている。展示スペース1の前部から前上部及び左側部にはそれぞれ透明なガラス板3が嵌め込まれ、ショーケースの前側からガラス板3を通して収納された食材が見えるようになっている。また、展示スペース1の後部には透明なガラス板4からなるスライド扉が設けられており、ショーケースの後側からガラス板4を通して収納された食材が見えると共にスライド扉を開けて展示スペース1内の食材の出し入れを行うように構成されている。
【0010】
図1に示されるように、機械室2内の冷凍回路構成部品に接続されて冷凍回路を構成しているエバポレータ5が、展示スペース1の上部及び底面6の裏側に設けられている。底面6は、ステンレス製で、少し前下がりに傾斜しており、その上に図示しないスノコが取り外し自在に置かれている。底面6の前端部には、庫内排水口8が開口されており、庫内排水口8に排水パイプ9の一端が接続されている。排水パイプ9の他端即ちパイプの出口11は、ショーケースの外部に導出されており、ここにL字管いわゆるエルボ16が回転自在に連結されている。エルボ16は排水方向を曲げるためのジョイントであって、軟質のゴム又はエラストマーの成形品から成り、通常時はその出口端17が横方向か下方向に向けられている。エルボ16は、出口端17が上方を向くように回転させたときには、出口端17の高さが庫内排水口8の高さ以上となるような寸法を有している。また、エルボ16の出口端17を下方に回転させたときに、真下にシンク等の排水口が位置していない場合には、図4に示したように、出口端17に排水ホースを連結して排水口に導くことが好ましい。
【0011】
次に、本実施の形態に係る冷蔵ショーケースの動作について説明する。通常運転時即ち展示スペース1内を冷却する場合、展示スペース1からの冷気の漏出及び外部からの害虫の進入を防ぐために庫内排水口8を図示しない栓で塞ぎ、スノコを敷いた状態で冷凍回路を作動させて展示スペース1内を冷却する。展示スペース1内は冷凍回路からエバポレータ5に供給される冷媒によって上下から冷却され、展示スペース1内のスノコ上に配置された食材が冷却される。展示スペース1の前部から前上部及び後部にはそれぞれ透明なガラス板3,4が嵌め込まれているため、冷却されている展示スペース1内の食材を外部から見ることができる。
展示スペース1内を洗浄する場合には、まずスノコ7を取り外し、庫内排水口8の栓を抜いて開口させる。この状態で、例えば展示スペース1内に水を流し、洗剤を用いてスポンジ等で擦り洗いを行う。この洗浄によって発生する汚水や食材の残留物等の汚物は庫内排水口8から排水パイプ9及びエルボ16を通ってショーケースの外部へ排出される。
【0012】
このようにして展示スペース1内を洗浄した後、排水パイプ9の内部の洗浄及び消毒を行う。まず、排水ホースがエルボ16の出口端17に接続されている場合には、その排水ホースを取り外し、次に図1に示されるように、エルボ16の出口端17を回転させて上方に向け、この出口端17から排水パイプ9内に次亜塩素酸ソーダの希釈液からなる洗浄剤を注入する。このとき、エルボ16の出口端17を上方に向けたときの高さが庫内排水口8の高さ以上となっているため、庫内排水口8まで、排水パイプ9全体に渡って洗浄剤を満たすことができる。この状態で、一定時間経過後、エルボ16の出口端17を横又は下方に回転させ、排水パイプ9内の洗浄剤を排出させて回収、廃棄する。その後、殺菌効果を高めるために排水パイプ9内を水洗することなく乾燥させる。
【0013】
このように、排水パイプ9内を洗浄する際に、エルボ16を排水パイプ9から取り外すことなく、回転させるだけで、洗浄剤を排水パイプ9内に満たすことができる。従って、エルボ16の着脱が不要になったため、排水パイプ9内の洗浄作業が容易になった。
また、従来排水パイプ9の出口を塞ぐために用いた栓が不要になったので、省資源及び省コストを図ることができると共に栓の紛失により排水パイプ9内の洗浄ができなくなる事態が回避され、冷蔵ショーケースを常に衛生的に使用することができる。
また、洗浄剤の注入をエルボ16の出口端17即ち展示スペース1の外部から行うため、誤って展示スペース1の底面6に洗浄剤をこぼして錆を発生させることがなく、冷蔵ショーケースの寿命を延ばすことができる。また、エルボ16の出口端17が冷蔵ショーケースの背面側即ち厨房側に位置するので、洗浄剤の注入作業を行いやすい。
【0014】
【発明の効果】
以上説明したように、本発明の冷蔵ショーケースによれば、回転可能に排水パイプに連結するエルボの出口端を上方に向けた場合にエルボの出口端が庫内排水口の高さ以上となり、このエルボの出口端から洗浄剤を排水パイプに充たすことができるので、エルボの着脱をすることなく容易に排水パイプ内の洗浄を行うことができる。更に、出口端は展示スペース外に設けられているので、展示スペース内の底面に誤って錆を発生させるおそれがなくなり、製品寿命を延ばすことができる。
また、本発明の排水パイプの洗浄方法によれば、外部に連通する排水パイプの端部に回転自在にエルボを連結し、エルボの出口端を上方に向けてこの出口端から排水パイプ内に洗浄剤を注入することで、排水パイプ内の洗浄が容易になると共に展示スペース内の底面に誤って錆を発生させることが防止され、冷蔵ショーケースの長寿命化を図ることができる。

Transparent glass plates 3 are fitted from the front part to the front upper part and the left side part of the exhibition space 1 so that the food stored through the glass plate 3 can be seen from the front side of the showcase. In addition, a slide door made of a transparent glass plate 4 is provided at the rear part of the exhibition space 1 so that food stored through the glass plate 4 can be seen from the rear side of the showcase and the slide door is opened to open the interior of the exhibition space 1. It is configured to take in and out the ingredients.
[0003]
FIG. 3 shows a cross-sectional view of the refrigerated showcase. An evaporator 5 connected to the refrigeration circuit components in the machine room 2 and constituting the refrigeration circuit is provided on the upper part of the display space 1 and the back side of the bottom surface 6 to cool the foods placed on the slats 7. . Further, the bottom surface 6 is inclined downward toward the front, and the in-compartment drain port 8 is opened at the front end portion which is the lowest portion of the bottom surface 6. A drainage pipe 9 that is inclined downward toward the rear of the showcase is connected to the interior drain outlet 8, and the drainage from the interior is discharged to the outside through the drainage pipe 9. . During normal operation of the refrigerated showcase, that is, when the display space 1 is cooled, the internal drainage port 8 is provided with a detachable plug 10 for leakage of cold air from the display space 1 and pests from the outside. Prevent intrusion.
[0004]
In such a refrigerated showcase, the interior of the exhibition space 1 becomes dirty with use, and therefore, the interior of the exhibition space 1 is generally cleaned after the end of business. At the time of cleaning, the cooling operation is first stopped and the slat 7 is taken out, and then the stopper 10 that has closed the internal drainage port 8 is removed. Thereafter, water is poured into the exhibition space 1, and the detergent is rubbed with a sponge or the like. Dirty water such as water and detergent and filth such as food residue are discharged from the interior drainage port 8 through the drainage pipe 9 to the outside of the showcase. Here, as shown in FIG. 4, an L-shaped pipe so-called elbow 12 is connected to the outlet 11 of the drainage pipe 9, and further, sewage and filth are sinked through a drainage hose 13 connected to the elbow 12. 14 drains. When the sink 14 is positioned directly below the elbow 12, the drainage hose 13 is not used, and the drainage hose 13 is not directly drained from the elbow 12 to the sink 14.
[0005]
In this way, the interior of the exhibition space 1 is cleaned. However, since the inside of the drainage pipe 9 tends to become unsanitary due to the passage of sewage and filth, the inside of the drainage pipe 9 needs to be cleaned. However, since the inside of the drain pipe 9 is thin and has a bent portion depending on the case, it is difficult to clean it directly. Therefore, as shown in FIG. 5 in the prior art, at the time of cleaning, the elbow 12 connected so far is removed, and instead a soft rubber plug 15 is fitted into the outlet 11 of the drainage pipe 9 to close this state. Then, the cleaning agent is injected from the display space 1 into the drain outlet 8 in the cabinet, and the drain pipe 9 is filled with the cleaning agent. It is left as it is for a certain period of time, and after the cleaning of the drain pipe 9 is completed, the stopper 15 of the outlet 11 is removed and the cleaning agent is discharged. Thereafter, the cleaning agent adhered in the drain pipe 9 is dried without washing the drain pipe 9 with water or the like. This is to prevent a decrease in the bactericidal effect of the cleaning agent. In many cases, the drain pipe 9 is made of a hard resin, and a dilute solution of sodium hypochlorite is generally used as the cleaning agent.
[0006]
[Problems to be solved by the invention]
However, when filling the inside of the drain pipe 9 with the cleaning agent, the work of removing the elbow 12 and plugging it in place of the elbow 12 is troublesome and troublesome. Further, since the plug 15 is not always used, it is easily lost. If the plug 15 is lost, the drain pipe 9 cannot be cleaned, and the drain pipe 9 may become unsanitary.
In addition, since a dilute solution of sodium hypochlorite is used as a cleaning agent, if it is accidentally spilled on the bottom surface 6 when it is poured into the internal drainage port 8, it causes rust on the bottom surface 6. It becomes. Although the bottom surface 6 of the exhibition space 1 is made of stainless steel, the cleaning agent becomes highly concentrated by drying, so even rust-resistant stainless steel will generate rust, thus extending the product life of the refrigerated showcase. There is a risk of shortening.
[0007]
The present invention has been made to solve the above-described problems, and it is possible to easily clean the inside of the drain pipe and to prolong the life of the product. An object is to provide a cleaning method.
[0008]
[Means for Solving the Problems]
In order to achieve the above-described object, the refrigerated showcase according to the present invention has one end of a drain pipe connected to the interior drain opening opened at the bottom of the exhibition space and the other end of the drain pipe communicating with the outside. The elbow is connected to the other end of the drain pipe so as to be rotatable, and the elbow is rotated so that its outlet end faces upward. It has the dimension which becomes more than the height of.
Further, the drain pipe cleaning method according to the present invention is a drain pipe cleaning method in which one end is connected to the drain outlet in the warehouse opened at the bottom of the display space of the refrigerated showcase and the other end communicates with the outside. , An elbow is rotatably connected to the other end of the drainage pipe, and a cleaning agent is injected into the drainage pipe from the exit end with the exit end of the elbow facing upward.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the accompanying drawings.
FIG. 1 shows a cross-sectional view of the refrigerated showcase according to the present embodiment. The refrigerated showcase of this embodiment is an improvement of the cleaning method in the drain pipe 9 in the conventional refrigerated showcase shown in FIG. 2, and has the same overall configuration as the showcase of FIG. Yes. That is, an exhibition space 1 for displaying foods while refrigerated and a machine room 2 in which refrigeration circuit components such as a compressor and a condenser for cooling the exhibition space 1 are housed are provided adjacent to each other. . Transparent glass plates 3 are fitted from the front part to the front upper part and the left side part of the exhibition space 1 so that the food stored through the glass plate 3 can be seen from the front side of the showcase. In addition, a slide door made of a transparent glass plate 4 is provided at the rear part of the exhibition space 1 so that food stored through the glass plate 4 can be seen from the rear side of the showcase and the slide door is opened to open the interior of the exhibition space 1. It is configured to take in and out the ingredients.
[0010]
As shown in FIG. 1, an evaporator 5 connected to the refrigeration circuit components in the machine room 2 and constituting the refrigeration circuit is provided on the upper portion of the exhibition space 1 and on the back side of the bottom surface 6. The bottom surface 6 is made of stainless steel, and is inclined slightly forward and downward, and a slat (not shown) is detachably placed thereon. In the front end portion of the bottom surface 6, a warehouse drain port 8 is opened, and one end of a drain pipe 9 is connected to the cabinet drain port 8. The other end of the drainage pipe 9, that is, the outlet 11 of the pipe is led out of the showcase, and an L-shaped tube so-called elbow 16 is rotatably connected thereto. The elbow 16 is a joint for bending the direction of drainage, and is made of a molded product of soft rubber or elastomer. Normally, its outlet end 17 is directed laterally or downward. When the elbow 16 is rotated so that the outlet end 17 faces upward, the elbow 16 has a dimension such that the height of the outlet end 17 is equal to or higher than the height of the internal drainage port 8. In addition, when the outlet end 17 of the elbow 16 is rotated downward and a drain outlet such as a sink is not located directly below, a drain hose is connected to the outlet end 17 as shown in FIG. To the drain outlet.
[0011]
Next, the operation of the refrigerated showcase according to the present embodiment will be described. During normal operation, that is, when the interior of the exhibition space 1 is cooled, in order to prevent the leakage of cold air from the exhibition space 1 and the entry of pests from the outside, the interior drainage port 8 is closed with a stopper (not shown) and frozen in a state in which a slat is spread The display space 1 is cooled by operating the circuit. The display space 1 is cooled from above and below by the refrigerant supplied to the evaporator 5 from the refrigeration circuit, and the food disposed on the slats in the display space 1 is cooled. Since the transparent glass plates 3 and 4 are fitted from the front part to the front upper part and the rear part of the exhibition space 1, the foodstuffs in the cooled exhibition space 1 can be seen from the outside.
When cleaning the inside of the exhibition space 1, the slat 7 is first removed, and the plug of the interior drainage port 8 is pulled out and opened. In this state, for example, water is poured into the exhibition space 1, and scrubbing with a sponge or the like is performed using a detergent. Waste such as sewage and food residue generated by this washing is discharged from the interior drainage port 8 through the drainage pipe 9 and the elbow 16 to the outside of the showcase.
[0012]
After cleaning the inside of the exhibition space 1 in this way, the inside of the drain pipe 9 is cleaned and disinfected. First, when the drain hose is connected to the outlet end 17 of the elbow 16, remove the drain hose and then rotate the outlet end 17 of the elbow 16 upward as shown in FIG. A cleaning agent made of a diluted solution of sodium hypochlorite is poured into the drain pipe 9 from the outlet end 17. At this time, since the height when the outlet end 17 of the elbow 16 is directed upward is equal to or higher than the height of the internal drainage port 8, the cleaning agent extends over the entire drainage pipe 9 up to the internal drainage port 8. Can be met. In this state, after the elapse of a certain time, the outlet end 17 of the elbow 16 is rotated sideways or downward, and the cleaning agent in the drain pipe 9 is discharged, recovered, and discarded. Thereafter, in order to enhance the sterilizing effect, the inside of the drain pipe 9 is dried without washing.
[0013]
Thus, when the inside of the drain pipe 9 is washed, the cleaning agent can be filled in the drain pipe 9 only by rotating the elbow 16 without removing the elbow 16 from the drain pipe 9. Therefore, since the elbow 16 is not required to be attached or detached, the cleaning operation inside the drain pipe 9 is facilitated.
Moreover, since the plug used for closing the outlet of the drainage pipe 9 is no longer necessary, it is possible to save resources and cost, and avoid the situation where the drainage pipe 9 cannot be cleaned due to loss of the plug. A refrigerated showcase can always be used in a sanitary manner.
Further, since the cleaning agent is injected from the outlet end 17 of the elbow 16, that is, from the outside of the display space 1, the cleaning agent is not accidentally spilled on the bottom surface 6 of the display space 1 to generate rust, and the life of the refrigerated showcase Can be extended. Further, since the outlet end 17 of the elbow 16 is located on the back side of the refrigerated showcase, that is, the kitchen side, it is easy to inject the cleaning agent.
[0014]
【The invention's effect】
As described above, according to the refrigerated showcase of the present invention, when the outlet end of the elbow that is rotatably connected to the drain pipe is directed upward, the outlet end of the elbow is equal to or greater than the height of the drain outlet in the warehouse, Since the drainage pipe can be filled with the cleaning agent from the exit end of the elbow, the drainage pipe can be easily cleaned without attaching or detaching the elbow. Furthermore, since the exit end is provided outside the exhibition space, there is no possibility of accidentally generating rust on the bottom surface in the exhibition space, and the product life can be extended.
Further, according to the drain pipe cleaning method of the present invention, the elbow is rotatably connected to the end portion of the drain pipe communicating with the outside, and the elbow outlet end is directed upward to clean the drain pipe from the outlet end. By injecting the agent, the drainage pipe can be easily cleaned and the bottom surface of the exhibition space can be prevented from being erroneously rusted, thereby extending the life of the refrigerated showcase.
