Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a blind cleaning device for removing dirt accumulated in a blind installed inside a window for light shielding.
[0002]
[Prior art]
The blinds are made of metal and plastic slats that are bundled with thin plates. By changing the angle of the slats, the sun can be blocked while maintaining air permeability, and direct sunlight from above can be blocked. It has features such as ensuring horizontal visibility while blocking, and is widely used in homes and offices. Since blinds are directly exposed to the outside air and the surface area of the slats is large, accumulation of dirt is fast, and it is aesthetically preferable to clean several times a year.
[0003]
When cleaning the blinds installed in the home, there are methods such as removing accumulated dust with a scrubber or wiping the surface of the slats with a scrubbing brush. Sometimes removed from the building and washed with water. However, when washing with water, careful work is required so as not to damage extremely thin slats, and the number of slats is large.
[0004]
[Problems to be solved by the invention]
Cleaning the blinds is not easy as described above, but if it is about a private house, it can be handled manually although it takes time. However, the blinds used in offices, hospitals, restaurants, etc. need regular cleaning from the viewpoint of aesthetics and hygiene, but they are larger than those for home use, and the number of installations is large. There are many problems in terms of time and cost. From this point of view, a device that automatically cleans the blinds has also been developed. As an example, a blind is immersed in a cleaning tank containing a cleaning solution, and ultrasonic waves are radiated to the cavitation. What performs washing | cleaning using the physical action of this is mentioned.
[0005]
The cleaning liquid used in this ultrasonic cleaning apparatus is obtained by adding chemicals to water. In order for the cleaning liquid to function efficiently, this temperature needs to be maintained at about 40 degrees Celsius. Therefore, in the past, a heating wire has been installed to surround the cleaning tank, and it is necessary to wait for an hour or more until the cleaning solution reaches the proper temperature. It is necessary to operate the heating wire, which increases power consumption. Further, when performing a series of cleaning operations, the workability cannot be said to be good, and further improvement is necessary.
[0006]
The present invention was developed on the basis of such a situation, and after reducing the energy consumption for maintaining the temperature of the cleaning liquid, the time until the start of the cleaning work can be shortened and the workability is also excellent. The purpose is to provide a blind cleaning device.
[0007]
[Means for Solving the Problems]
The invention according to claim 1, which overcomes the above-described problem, is a blind cleaning apparatus in which an ultrasonic transmitter is incorporated in a cleaning tank, and includes a hot water boiler for supplying hot water at a temperature set in the cleaning tank. It is characterized by. A cleaning solution obtained by diluting an alkaline undiluted solution with water is used for cleaning the blind. In order to make this cleaning solution function efficiently, it is necessary to maintain the temperature at about 40 degrees Celsius as described above. In order to achieve this, in the present invention, it is not necessary to heat water in the washing tank by injecting hot water heated to an appropriate temperature with a hot water boiler into the washing tank. it can. In the claims, “warm water at a set temperature” refers to hot water of about 40 degrees Celsius.
[0008]
The length of the blinds varies, but it is about 4m. In order to completely submerge them, the washing tank needs a length of about 4.5 m, but a width and a depth of about 50 cm are sufficient. In addition, the material of the washing tank is not limited, but a structure in which a durable metal plate such as stainless steel is welded and joined in a box shape is common, and the washing tank is not a size that can be easily carried, and is usually used in a building. To do. An ultrasonic transmitter is installed at the bottom of the cleaning tank, a signal generator for driving the ultrasonic transmitter is installed around the cleaning tank, and both are connected by a water-resistant electric wire. Yes. A grid-like cover is provided on the ultrasonic transmitter, and blinds are arranged on this.
[0009]
Although the temperature of the cleaning liquid in the cleaning tank decreases with time, in order to prevent this, as in the invention of claim 2, a heat retaining boiler for keeping the temperature in the cleaning tank constant, and in the cleaning tank A liquid suction port for returning the cleaning liquid to the heat retaining boiler via the first pipe line, a liquid injection port for heating the returned cleaning liquid with the heat retaining boiler and injecting it into the cleaning tank via the second pipe line, It is possible to prevent the temperature of the cleaning liquid from decreasing. The cleaning liquid whose temperature has dropped is extracted from the liquid suction port and sent to the heat insulation boiler via the first pipe, and the heated cleaning liquid passes through the second pipe from the liquid inlet to the cleaning tank. It spreads inside.
[0010]
The heat source of the heat insulation boiler is determined in consideration of maintenance and safety, but can be freely selected from kerosene, firewood, gas and electricity. However, in order to prevent corrosion and damage due to the cleaning liquid, the boiler interior and piping should be made of stainless steel. The thermal insulation boiler is not always operated, and when the temperature of the cleaning liquid is monitored and cooled down from the specified temperature, the thermal insulation boiler is operated and reheated. However, it is difficult to always perform this monitoring work manually. Usually, a thermometer is installed in a washing tank or in a heat insulation boiler, and a series of operations are automatically performed. Although the heat insulation boiler and the hot water supply boiler are installed individually in principle, the heat insulation boiler can also be used as the hot water supply boiler as in the invention described in claim 3, and in this case, the introduction cost of the apparatus can be reduced. .
[0011]
When the cleaning liquid is ready, blinds brought from various locations are put into the cleaning tank. In addition to slats, straps and metal fittings are attached to the blinds, but these are not removed and are put into the cleaning solution. The blind is placed on a cover that covers the ultrasonic transmitter, and the air adhering to the surface is released, and a preparatory work is performed so that the cleaning liquid is spread over the entire surface, and then ultrasonic waves are emitted from the ultrasonic transmitter. At this time, no work is required, and dirt is released by the physical action of ultrasonic waves and diffuses into the cleaning liquid.
[0012]
When the cleaning operation is completed, the blinds are taken out from the cleaning tank, but the cleaning liquid does not need to be replaced in a single operation and is used repeatedly until the cleaning ability is reduced. Therefore, although the temperature of the cleaning liquid gradually decreases when it is allowed to stand, in the present invention, the cleaning liquid can be maintained at an appropriate temperature by the heat retaining boiler. Although it is possible to clean the blinds day and night continuously, in consideration of cost and demand, the operation is usually performed for about 12 hours per day, and the work is not performed at night. Therefore, the operation of the heat insulation boiler is stopped at night, but if the operation of the heat insulation boiler is resumed before the start of the next morning, the cleaning liquid reaches the specified temperature after ten minutes and the work can be started.
[0013]
When the heat insulation boiler is operated continuously, fuel consumption increases. Therefore, as in the invention described in claim 4, a heat insulating material should be provided around the washing tank to suppress the temperature decrease as much as possible to reduce fuel consumption. As a specific method, the simplest method is to adhere a heat insulating material such as urethane foam to the side surface or bottom surface of the cleaning tank. In addition, when work is not performed for a long time such as at night, heat can be further suppressed by placing a lid on the washing tank.
[0014]
Blinds that have been cleaned with ultrasonic waves need to be washed with water to wash away the cleaning solution. Since the cleaning liquid is used repeatedly, it cannot be washed with water in the cleaning tank, and a separate rinsing tank is required. In consideration of the convenience at this time, it is desirable to provide a hose capable of installing a rinsing tank adjacent to the washing tank and supplying hot water to the entire area of the rinsing tank as in the invention described in claim 5. The rinsing tank is sized so that the blinds can be completely submerged in the same way as the washing tank, and the washing tank and the rinsing tank are arranged adjacent to each other so that the operation of moving the blinds from the washing tank to the rinsing tank can be performed quickly. Has been. Here, the term “adjacent” means that the blind picked up from the cleaning tank is at a distance that can be transported to the rinsing tank by one or two steps of movement. Further, by providing a hose so that hot water can be supplied to the entire area of the rinsing tank, the cleaning liquid remaining in the blind can be quickly poured off. In this specification, the flexible piping is referred to as a hose, and the hot water flowing through the hose can be supplied from a hot water boiler.
[0015]
It is possible to store warm water in the rinsing tank and immerse the blinds here and use the hose together to drop the cleaning solution. However, as in the invention according to claim 6, the blinds are supported without contacting the bottom surface of the rinsing tank. By providing a possible holding member, the cleaning liquid can be more reliably dropped. In order to quickly remove the cleaning liquid from the blinds, the drainage should be improved. Therefore, the blinds are not brought into contact with the bottom surface of the rinsing tank and are released into the air by the holding members. As an example of the holding member, there is a form in which a bar or net is suspended from above the washing tank and the blind is supported here.
[0016]
The holding member should be made of a thin bar or rope so as to make the contact surface with the blind as small as possible, and preferably has a structure that can be moved and removed as necessary. When the blind is released into the air of the rinsing tank by the holding member, the hot water radiated from the hose falls immediately including the cleaning liquid, and the position of the blind is increased, so that workability is improved.
[0017]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a schematic diagram showing the configuration of a blind cleaning apparatus according to the present invention. In the cleaning tank 2 for storing the cleaning liquid 3, the rinsing layer 6 for cleaning the washed blind 1 and the cleaning tank 2 An ultrasonic transmitter 4 that emits sound waves, a heat insulation boiler 9 for maintaining the temperature of the cleaning tank 2, and the like are included. The cleaning tank 2 has a length of 4.5 m in accordance with the shape of the blind 1 in order to completely bury the blind 1 in the cleaning liquid 3, but its width and height are 50 cm. Since this blind cleaning apparatus is installed and used in a building, the removed blinds 1 are collected and the cleaning operation proceeds. The blind 1 shown in the figure has a length of 2 m and can be placed in the cleaning tank 2 in the longitudinal direction.
[0018]
An ultrasonic transmitter 4 is installed at the bottom of the cleaning tank 2, and 40 KHz ultrasonic waves are radiated from the upper surface to the cleaning tank 2. In addition, since the manufacturing cost of the ultrasonic transmitter 4 is extremely high, a large number of general-purpose products are often arranged as shown in the figure. Further, the ultrasonic transmitter 4 does not operate independently, and a signal generator 5 that generates an alternating current is required separately. The durability between the ultrasonic transmitter 4 and the signal generator 5 is not affected by the cleaning liquid 3. It is connected with a characteristic electric wire. Prior to the cleaning operation, hot water heated by the hot water supply boiler 11 is poured into the cleaning tank 2 from the faucet 12, and the cleaning stock solution is diluted to prepare the cleaning liquid 3.
[0019]
The cleaning tank 2 and the rinsing tank 6 are integrally manufactured by welding a stainless steel plate, and each tank is placed on the frame 20 in consideration of workability. For this reason, when the blind 1 is moved from the cleaning tank 2 to the rinsing tank 6, the hand can be accommodated in the rinsing tank 6 simply by moving the arm into the cleaning tank 2 and picking it up. Above the wall surface of the rinsing tank 6, a holding member 15 obtained by deforming a steel round bar having a diameter of about 5 mm into a U shape is hung, and the blind 1 is placed thereon. The blind 1 placed on the holding member 15 is washed away by the hot water sprayed from the shower head 14, and this hot water is supplied from the hot water boiler 11.
[0020]
The cleaning liquid 3 needs to maintain a temperature of about 40 ° C. in order to fully exhibit its cleaning ability. A liquid suction port 7 and a liquid injection port 8 are installed on the side surface of the cleaning tank 2, The first pipe 21 and the second pipe 22 are connected. The temperature of the cleaning liquid 3 is always measured by the thermometer 10, and when it falls below the reference, the heat retaining boiler 9 is operated. Such temperature measurement of the cleaning liquid and operation of the heat insulating boiler 9 are automatically performed. In addition, a heat insulating material 18 having a thickness of about 1 cm is attached around the cleaning tank 2 (partially drawn in the figure) to suppress the temperature drop of the cleaning liquid 3.
[0021]
2 and 3 show the cleaning process of the blind 1 by the sectional views of the cleaning tank 2 and the rinsing layer 6, and FIG. 2 (a) shows the situation before the work is performed. Only the ultrasonic transmitter 4 and the cover 16 covering the ultrasonic transmitter 4 are installed while the cleaning tank 2 is empty. A U-shaped holding member 15 is suspended from the top in the rinsing tank 6. The bottoms of the cleaning tank 2 and the rinsing tank 6 are provided with drainage ports 17a and 17b, and the plugs are opened at this stage. Next, FIG. 2B shows a state in which the cleaning liquid 3 is stored in the cleaning tank 2 toward the start of the work. The drain port 17a of the cleaning tank 2 is closed with a plug and is about 40 degrees by the hot water boiler 11. The warm water adjusted to 1 is poured from the tap 12. Simultaneously with the injection of hot water, a predetermined amount of alkaline cleaning stock solution is added and the preparation is completed when a predetermined water level is reached.
[0022]
When the preparation of the cleaning liquid 3 is completed as shown in FIG. 2B, the operation of the heat insulation boiler 9 is started in order to keep this temperature constant. When the measured value of the thermometer 10 in the cleaning tank 2 is lowered to 38 degrees, the heat insulation boiler 9 is automatically activated and stops when the temperature exceeds 42 degrees. The heat insulation boiler 9 and the hot water supply boiler 11 use general-purpose boilers that use kerosene as fuel, thereby reducing fuel costs and equipment introduction costs.
[0023]
After the operation of the heat insulation boiler 9 is started, the blinds 1 collected from various places are sequentially placed on the cover 16 in the cleaning tank 2. At this time, it is possible to put a plurality of blinds 1 together so as to fill up the cleaning tank 2, but a certain margin is necessary so that the cleaning liquid can reach the slats sufficiently, and the air adhering to the surface. Remove as much as possible. FIG. 3 (a) shows a stage in which the blind 1 is cleaned by emitting ultrasonic waves. When ultrasonic waves are emitted from the ultrasonic transmitter 4 to the cleaning liquid 3, dirt is released by the action of the ultrasonic waves. Then, it diffuses into the cleaning liquid 3. The time for radiating the ultrasonic waves is about 5 minutes.
[0024]
FIG. 3B shows a stage in which the cleaning of the blind 1 is finished and the cleaning liquid is poured in the rinsing tank 6. When the emission of ultrasonic waves is finished, the blind 1 is scooped up manually and moved to the adjacent rinsing tank 6. The blind 1 is received by the holding member 15 in the rinsing tank 6, and the hot water sprayed from the shower head 14 through the hose 13 from the hot water supply boiler 11 is poured and the cleaning liquid is poured off. Since the blind 1 is supported by the holding member 15 and floats entirely in the air, the water drains quickly, and the hot water containing the cleaning liquid is discharged to the outside from the drain port 17b at the bottom of the rinsing tank 6. Thereafter, the blind 1 is dried in another place and returned to the original installation place.
[0025]
The cleaning liquid 3 in the cleaning tank 2 can be used a plurality of times, and it is necessary to keep the temperature of the cleaning liquid 3 so that the next operation can be started anytime after the blind 1 is cleaned. The operation of 9 is continued. However, when the operation of cleaning the blind 1 of that day is finished in the evening, the operation of the heat insulation boiler 9 is stopped, but a lid 19 that covers the top of the cleaning tank 2 may be placed in order to suppress the temperature drop of the cleaning liquid 3. At the start of the next morning, when the operation of the heat insulation boiler 9 is resumed, the cleaning liquid 3 reaches a specified temperature in ten minutes. When the cleaning liquid 3 is replaced or on a long holiday, the operation of the heat insulation boiler 9 is stopped to remove the cleaning liquid 3.
[0026]
