Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an automatic detergent dispenser for a commercial fully automatic washing machine. More specifically, the present invention relates to an automatic detergent dispensing machine that automatically dispenses detergent according to various types of dirt in conjunction with the process of a commercial fully automatic washing machine, and also automatically controls temperature.

[Conventional technology]

Commercial washing machines are broadly divided into manual washing machines called open washers and fully automatic washing machines.

In a manual washing machine, not only the detergent is added, but also the amount of washing water and the temperature of the washing water are manually adjusted. Fully automatic washing machines are card-operated and the process can be controlled by a microcomputer. The contents of process control include the amount of washing water, temperature, time, etc. in processes such as preliminary washing, main washing, and rinsing.

Some fully automatic washing machines come with automatic detergent dispensers, but it is necessary to measure the detergent beforehand and put it into the automatic dispenser. There are commercially available automatic detergent dispensers, but they are not linked to the process of commercial washing machines.

On the other hand, an automatic loading machine linked to the process of a washing machine is also known in the literature (Japanese Patent Application Laid-open No. 70368/1983).

[Problem that the invention seeks to solve]

The linen supply industry that uses commercial washing machines depends on the sector to which the clothes are lent: ■) Hotel linen for hotels such as Hotenope Inn and Motil, 2) Hospital linen, 3) Industrial linen for factories, offices, department stores, etc. 4) Passenger cars, ships,
These include railway linen for aircraft, etc., 5) food linen for restaurants and cafeterias, and 6) rental diapers. Clothes are stained with various types of stains depending on the field in which they are loaned.

In the linen supply industry, there are often multiple lending areas.
It is complicated to wash clothes by changing the washing conditions and detergent, and in reality, depending on the type of clothes and stains,
It is difficult to carefully select different cleaning agents due to the complexity of the work and the qualifications of the workers. Because the linen supply industry does not use different cleaning processes and detergents for different types of stains, the linen supply industry faces problems with stains such as blood, medical drugs, animal and vegetable oils, and fecal stains on rental diapers, which remain as stains and cannot be rewashed. It is being said. Rewashing has been a major issue for the linen supply industry, as it reduces laundry processing capacity, deteriorates clothing, and discards clothing whose stains cannot be removed. Therefore, there has been a desire for a cleaning method that does not create stains, by selecting the optimal cleaning process and cleaning agent for each stain.

The electronic detergent dispensing system described in Japanese Patent Application Laid-open No. 48-70368, which was mentioned above, automatically dispenses chemicals in conjunction with the process of the washing machine. There is no mention of the need to select the washing process, and therefore the above-mentioned problems in the linen supply industry cannot be solved, which is the reason why it has not become widespread.

[Means for solving problems]

From this point of view, the present inventors have diligently researched cleaning processes and detergents that are suitable for various types of linen supply clothing and stains, and have also introduced cleaning agents that can handle various types of stains in one machine in conjunction with commercial fully automatic washing machines. We conducted extensive research on automatic loading machines and completed the present invention.

That is, the present inventors have studied the optimization of cleaning processes and cleaning agents that do not cause stains in the linen supply industry, where conventional cleaning methods cause stains and require frequent rewashing, and as a result, the following findings were obtained.

1) The blood-stained cloth is pre-washed in an alkaline solution containing an aqueous polymer compound at 0°C or lower, and then main-washed at 50-80°C with a cleaning solution containing a bleaching agent.

2) Hospital clothing should be pre-washed with an acid solution containing an organic or inorganic acid at a temperature below 50°C, and then washed with a cleaning solution containing bleach for 50 minutes.
Main washing is carried out at 0 to 80°C.

3) Linen for dining and banquets should be pre-washed at 60-80°C with an acid solution of pH 1.5-6, and then main-washed at 60-80°C with a cleaning solution containing bleach, alkaline builder and detergent, or Alternatively, after preliminary cleaning with an acid solution of pH 1.5 to 4 containing an organic peracid, main cleaning is performed with a cleaning solution containing an alkali builder and a detergent.

4) The diaper is pre-washed at 50°C or lower with water, an alkaline solution, or an alkaline solution containing a water-soluble polymer compound, and then main-washed at 50-80°C with a washing solution containing a bleaching agent.

5) Clean lightly soiled clothing with a cleaning solution containing alkaline builder, bleach and detergent.

6) Furthermore, if necessary, treat with a softener or sizing agent during rinsing.

As described above, in order to clean various contaminated cloths in the linen supply industry, at least an acid solution, an alkaline solution, a detergent solution, and a bleach solution are required as cleaning agents. In addition, a cleaning agent such as a softener solution or a glue solution may be required depending on the case.

Therefore, the inventors of the present invention stored each of these cleaning agents in separate cleaning agent containers, connected each container to the washing machine through a conduit, and sent each cleaning agent to the washing machine through the conduit using a tube pump. The microcomputer has the function of selecting the type and amount of each cleaning agent required for each type of washing process for each type of clothing, operating the tube pump for the required time, and controlling the washing temperature of each washing process. If you set it up,
The inventors have discovered that the cleaning process can be carried out automatically and easily, leading to the present invention.

That is, the present invention provides: (a) a plurality of detergent containers containing respective detergents such as an acid solution, an alkaline solution, a detergent solution, a bleach solution, and if necessary, a softener solution and a glue solution; Multiple tube pumps and conduits that send each cleaning agent to the machine (c) Reads the washing process of the washing machine, selects each cleaning agent required for the cleaning process for each type of clothing or dirt, and calculates the amount of each cleaning agent. The present invention provides an automatic detergent dispenser comprising a microcomputer having a function of operating a tube pump for a required period of time and a function of controlling the cleaning temperature in each cleaning process.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The automatic detergent dispenser of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is an equipment flow diagram of an automatic cleaning agent dosing machine of the present invention.

In the present invention, a tube pump 4 and a conduit 2 for delivering the cleaning agent to the washing machine 5 are provided separately for each of the cleaning agent containers 1. This mode is necessary to prevent the dangers of mixing acids, alkalis, bleaches, etc. in high concentrations. Tube pumps are convenient and easy to control for accurately delivering small amounts of liquid.

As the material of the tube of the tube pump 4 used in the present invention, rubber such as silicone resin, urethane resin, soft vinyl chloride resin, and neoprene can be used. Preferably, silicone resin is used, and it is desirable that the distance between the pump and the rotor is at most twice the tube wall thickness. Further, it is desirable to provide a check valve in the conduit 2 between the cleaning agent container 1 and the pump P. Further, it is desirable to attach a sensor 3 to the cleaning agent container to check the amount of remaining liquid, and to notify the user by a buzzer or a blinking lamp when the remaining amount is low.

The microcomputer 6 of the automatic detergent dosing machine of the present invention is input with the type of detergent required for the washing process according to the type of clothing or dirt and the amount of detergent according to the capacity of the washing machine.

The interlocking with a washing machine will be explained using an example using a commercial fully automatic washing machine MOX-20 manufactured by Tokyo Sensen Seisakusho.

MOX-20 allows process control using a card system, and uses microswitches for process control. M
I connected the unused spare three-process microswitch of OX-20 to the automatic detergent dispenser, coded the microswitch's ON and OFF signals as shown below, and created a card to recognize the washing process. .

1 indicates that the microswitch is ON.

0 indicates that the microswitch is FF.

In this way, by setting the type of clothing and washing capacity in the microcomputer 6, it can read the washing process of the washing machine, select the detergent necessary for that process, calculate the amount of detergent, and The pump 4 is operated to automatically inject the cleaning agent.

As mentioned above, in the linen supply industry, the optimum washing temperature in the washing process differs depending on the type of clothing and how dirty it is. General fully automatic commercial washing machines also have a temperature control function, but most are one-point or two-point types, and if the optimal washing temperature differs depending on the washing process, you must manually set the temperature control dial. No. However, in the present invention, the temperature sensor of the washing machine and the steam control valve are used to control the temperature of the washing machine with the microcomputer of the automatic detergent dosing machine. Creating cleaning conditions.

〔Effect of the invention〕

The automatic detergent dispenser of the present invention can select the type and amount of detergent required for the washing process according to the type of clothing or dirt, and automatically dispense the detergent according to the washing process of the washing machine. Moreover, since the cleaning temperature of each cleaning process can be controlled,
You can easily perform the complicated cleaning work of various stains that are a problem in the linen supply industry.
