BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning apparatus for cleaning sofas, curtains, etc., and more particularly to a cleaning apparatus that supplies a heated cleaning liquid to a sofa or the like and sucks the cleaning liquid using a vacuum means.

0002

[Prior Art] A nozzle is arranged near the suction port of a vacuum means to supply water vapor to a surface such as a carpet.
A carpet cleaning device that sucks this dirt together with dirt is described in Japanese Patent Laid-Open No. 61-29324.

[0003] This device uses water as a cleaning liquid, is heated with a small propane stove, and is configured to clean with steam.

0004

[Problems to be Solved by the Invention] Sofas, curtains, and the like are made of a variety of materials and are also difficult to remove stains from simply washing with water, as they are subject to various types of stains. Furthermore, some materials may shrink when water or steam is used, and it is preferable to use a special dry cleaning solution for materials that have problems with drying or the negative effects of residual moisture.

According to the Swedish principle of Arrhenius, when the temperature exceeds 48°C, the flow of molecules is twice as large for every 8°C, and at 96°C, the flow of molecules is 64 times that at 48°C, and boiling water is a natural surfactant. It is said that there is.

[0006] It is specified that the cleaning liquid should be heated to a predetermined temperature, for example, 48°C or 93°C, depending on the material of the sofa or the like to be cleaned, but if the temperature is outside this range, the cleaning ability will be significantly reduced. In addition to lowering the temperature, there is also a risk of damaging the material if it moves to the high temperature side.

[0007] For large stationary type equipment that uses a large amount of cleaning liquid, it is easy to prepare the cleaning liquid by heating it to a constant temperature in a constant temperature bath, but for portable, lightweight and small equipment, it is easy to heat the cleaning liquid to a constant temperature in a constant temperature bath. If the amount of cleaning liquid used at one time is small, it is difficult to constantly supply cleaning liquid at a predetermined temperature. For example, even when the cleaning liquid heated to a predetermined temperature is introduced to the suction port of the vacuum means, the temperature fluctuates significantly due to differences in outside temperature, making it difficult to maintain the cleaning liquid at a predetermined temperature. Another possibility is to supply high-temperature cleaning liquid in anticipation of the temperature drop in the supply path, but if the supply path is warmed, the temperature drop in the supplied cleaning liquid will be reduced, and the high-temperature cleaning liquid will be applied to sofas, etc. Depending on the material, irreversible damage may occur.

In view of the above, the present invention provides a sofa and a curtain that are small and lightweight, use a relatively small amount of cleaning liquid, and have an improved constant temperature means that can supply the cleaning liquid at a stable temperature. The purpose of this study is to clarify cleaning equipment such as the following.

[0009]

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention provides a valve for converting the supply path of the cleaning liquid to the nozzle for spouting the cleaning liquid prepared in the suction part of the vacuum means. is circulated in the path of cleaning liquid tank → pump → heating means → cleaning liquid supply pipe → circulation guide pipe → cleaning liquid tank, the temperature of the cleaning liquid is detected by a temperature sensor placed in the path, and the heating means is heated according to the detected data. It is characterized by having a means for controlling the temperature of the cleaning liquid by adjusting the output of the cleaning liquid.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described in detail according to embodiments shown in the accompanying drawings.

In FIG. 1, reference numeral 10 indicates a main body frame;
It is configured so that it can be moved by wheels 11, and inside, a cleaning liquid tank 20, a pump 21, a heat exchanger 30, an electronic control device 40, a vacuum means 50, etc. are arranged, and an outside is equipped with a vacuum means. A guide tube 60, a hand tool 61 attached to the tip thereof, a cleaning fluid supply tube 22, a guide tube 23 for circulating cleaning fluid, and the like are arranged.

The cleaning liquid is stored and prepared in a cleaning liquid tank 20, and the cleaning liquid is added or the tank is cleaned by opening a lid provided at the top.

Various types of pumps 21 can be used, but one that is small and lightweight, has high power, and produces low noise is preferably used.

Since the heat exchanger 30 is used as a means for heating the cleaning liquid, it is not limited to a type in which a coiled tube is placed in a heat source as shown in the figure, but also a submerged type, or
An external heater may be used, or the heater may be placed in the cleaning liquid tank 20.

Now, the cleaning liquid pumped out by the pump 21, passed through the heat exchanger 30 and heated to a predetermined temperature, passes through the supply pipe 22 and reaches the hand tool 61. This hand tool 61 is available in different versions for sofas and curtains, but the only difference is in the structure of the opening 62 for suction, and the other configurations are the same. A nozzle 24 for ejecting water is prepared.

The hand tool 61 is also provided with a lever 63, which operates the valve 25 that connects the cleaning fluid supply pipe 22 and the circulation guide pipe 23. When the lever 63 is released, the cleaning liquid is sprayed from the nozzle 24, and when the lever 63 is released, the valve 2 is released.
5 is converted and the cleaning liquid is guided to the guide tube 23,
It returns to the cleaning liquid tank 20.

It goes without saying that the valve 25 may be switched by means other than the lever 63.

It is also preferable to prepare a plurality of different types of nozzles 24 so that the ejection state and ejection pressure of the cleaning liquid can be changed by operating the lever 63 described above.

Furthermore, it is also preferable to arrange a filter in front of the nozzle 24 to prevent the nozzle 24 from clogging.

The cleaning liquid ejected from the nozzle 24 is supplied to the surface of the sofa or the like to perform a cleaning action, and then is sucked from the opening 62 of the hand tool 61, passes through the guide pipe 60, and reaches the vacuum means 50. , separated from air,
The waste liquid is stored in the waste liquid tank 51. Note that the dry liquid waste liquid can be reused as a cleaning liquid after being screened.

Now, the temperature of the cleaning liquid spouted and circulated as described above is strictly controlled by the electronic control unit 40. That is, the temperature of the cleaning liquid discharged from the heat exchanger 30 is detected by the temperature sensor 41. is performed, and the output of heating means such as a heater is controlled according to the detected data. It is preferable that the temperature sensor 41 is placed as close as possible to the nozzle 24, but in consideration of the circulation of the cleaning liquid, the temperature sensor 41 is selected to be placed before, in the middle of, or after the valve 25.

[0022] The temperature sensor 41 may be disposed only immediately after the heat exchanger 30, or may be disposed at a plurality of locations along the cleaning liquid circulation path. Furthermore, various types of temperature sensors can be used as the temperature sensor 41, including an electronic type that detects increases and decreases in electrical resistance due to temperature, and a mechanical type such as a bimetal type.

[0023]

Effects of the Invention Now, since the cleaning device of the present invention is constructed as described above, it is possible to input the cleaning liquid into the cleaning liquid tank 20 and input the type of data to the electronic control unit.
When started, the cleaning liquid is pumped by the pump 21 to the cleaning liquid tank 20 → heat exchanger 30 → supply pipe 22 → valve 25.
The cleaning liquid is circulated in the following order: → guide pipe 23 → cleaning liquid tank 20. During this time, the temperature is detected by the temperature sensor 41, and the heater etc. are adjusted according to the data, so that the cleaning liquid at the optimum temperature is always being circulated. hand tool 6
If you squeeze the lever 63 of 1, the cleaning liquid at the optimum temperature will be sprayed into the nozzle 24.
Since it becomes possible to eject water from the air, a cleaning device that solves the above-mentioned problems can be obtained.
