Abstract

PURPOSE:To facilitate maintenance and enhance the sound insulating performance by forming a suction passage surrounded by sound insulation within the door, and arranging the outlet from this suction passage so as to mate closely with the opening of a guide passage on a sound insulation chamber when the door is shut. CONSTITUTION:At a door 3 a suction passage 22 is equipped, which is surrounded by sound insulation 10, that should contribute to suppressing the space. In order to make sufficient cooling of a prime mover 13, it is equipped with an exhaust fan 14a and an external cooling air guide passage 21 on different sides of the prime mover installation position. Because the outlet 22b from this suction passage 22 mates closely with the opening 21a of the guide passage on the sound insulation chamber 1 side when the door is shut, the chamber 1 can easily be opened fully to facilitate maintenance operations. As the door 3 is of sliding type, no extra space for opening and shutting is required in front thereof.

Description

Detailed Description of the Invention "Industrial Application Field" The present invention uses pressurized hot water containing a cleaning agent to clean the floor surfaces of restaurants, hotels, offices, etc. where jutetan is mainly laid. The present invention relates to a pressure washing device that performs pressure washing by spraying onto the floor surface and then vacuum suctioning the washed waste water.

``Prior Art'' Conventionally, a pressure washer is known, which performs pressure washing while spraying pressurized water containing a cleaning agent onto the jutan, and then vacuum suctions the dirty water after washing. Among the equipment, especially large commercial cleaning equipment, there are pumps that compress the cold water introduced into the equipment to generate pressurized water.
A heat exchanger for heating the generated pressurized water, a generator for controlling the heating, etc., a blower for vacuum suction of the sewage after cleaning, a recovery tank for recovering the sewage after washing, and the pump, blower, and power generation. Because the machine has a built-in prime mover that provides rotational force, it is inevitably large in size, and the noise generated by the prime mover is also large, so the machine must be moved adjacent to the cleaning site. It is impossible to install the cleaning equipment in a vacuum cleaner, and this is because cleaning using a large equipment like the one mentioned above is generally carried out by a professional cleaning company while visiting each building. - Generally, the main body of the device is housed in a soundproof room installed on the bed of a truck, and an injection port for injecting pressurized hot water and a pipe for sucking sewage are installed through piping connected to the device from outside. The suction port is connected to an integrated cleaning member, and the cleaning member alone is sequentially moved from one cleaning site to another in a building to perform cleaning. The cleaning procedure for such a pressure washer is described in detail in the utility model registration application ``Pressure Washer'' filed by the applicant on January 21, 1983.

``Problem to be solved by the invention'' However, in general, cleaning of restaurants, hotels, offices, etc.
Because these events are held on holidays and at night when the business is not open,
Considering the influence of adjacent third parties, the prime mover, pump,
It is necessary to pay extreme attention to the soundproofing performance of a soundproof room that houses blowers, generators, etc., but in order to avoid a rise in temperature inside the soundproof room, it is necessary to always keep the intake and exhaust ports for introducing and discharging cooling air. Further, the soundproof room must be provided with an opening/closing door to facilitate maintenance of the pumps, blowers, etc. housed therein, and both of these serve to reduce the soundproofing effect.

Furthermore, since the device is generally installed on the loading platform of a truck, it is necessary to make it as compact as possible, and it is also necessary to perform maintenance easily in a narrow space.

In particular, in the above-mentioned apparatus, in addition to a soundproof room that houses the pump, blower, prime mover, etc., a collection tank must be provided to collect wastewater after cleaning, and it is difficult to arrange these efficiently.

The purpose is to provide a pressure washer with improved soundproofing performance while avoiding temperature rise.

Another object of the present invention is to provide a pressure washing device that requires less installation space and can be easily maintained even when the device is installed on the bed of a truck.

"Means for Solving the Problem" In order to achieve the technical problem, the present invention 1 has at least a pump 11 for generating pressurized water, a blower 12 for vacuum suction of waste water. and a prime mover 1 that provides driving force to these
3 is housed in a soundproof room 1, and a fan 14a installed in the soundproof room 1 sucks in and discharges external cooling air. 4I! 13. The fans 14a... and the external cooling air guide passage 21 are arranged across the mounting position, and an opening/closing door 3 having a sliding door structure guided along a guide is provided on one side wall of the soundproof room 1. ,
A suction passage 22 surrounded by a soundproof material 10 is formed in the opening/closing door 3, and an outlet opening 22b of the suction passage 22 is
The first aspect of the invention is characterized in that the door 3 is configured to coincide with the guide passage opening 21a on the soundproof room 1 side when the door 3 is closed.

In addition, in the invention of part 2, an opening/closing door 3 having a sliding door structure guided along a guide is provided on one side wall surface of the soundproof room l, and an opening/closing door 3 having a sliding door structure is provided on one side wall surface of the soundproof room l, and the external The structure is configured such that cooling air can be introduced into the soundproof room 1, and a recovery tank 4 is provided adjacent to the soundproof room 1 on the moving direction side of the groove 3, and the blower 12 suction pipe 15 is inserted into the recovery tank 4. The suction pipe 15 is surrounded by a soundproof box 1B.

"action" The present invention will be described in detail using such technical means.

First, in the first invention, since the suction passage 22 for introducing external cooling air into the opening/closing door 3 is formed, there is no need to provide an independent suction passage 22, and the space can be saved.

In addition, the suction passage 22 is not directly introduced into the soundproof room l, but rather into the soundproof room! Since it is diffused in the side guide passage 21 and introduced indirectly, the soundproofing effect increases accordingly, and
The guide passage 21 allows external cooling air to be introduced from the most preferable position within the soundproof room 1.

In particular, in this embodiment, since the fans 14a and the external cooling air guide passage 21 are arranged on both sides of the mounting position of the prime mover 13, the prime mover 13, which has the highest thermal energy, can be sufficiently cooled.

Furthermore, the guide passage 21 and the suction passage 22 are not connected to each other, and the outlet opening 22b of the suction passage 22 is configured to match the guide passage opening 21a on the soundproof room 1 side when the door 3 is closed, so that soundproofing is achieved. It is easy to open the entire chamber 1, and as a result, maintenance work is extremely facilitated.

Moreover, since the opening/closing door 3 has a sliding door structure rather than a front-opening structure, it does not require extra opening/closing space on the front side.
In particular, because of the sliding door structure, the vehicle can be opened even in a narrow place such as the loading platform 6 of a truck 5.

In addition, in the second invention, in accordance with the above-mentioned effect, since the recovery tank 4 is provided adjacent to the soundproof room 1 on the moving side of the groove 3, the space is reduced without creating a dead space on the moving direction side of the door. It can be used effectively.

Furthermore, by inserting the blower 12 suction pipe 15 into the recovery tank 4 and surrounding the suction pipe 15 with a soundproof box 1B, the recovery tank 4 can also function as a vacuum tank, making the device more compact. is further achieved, and the suction pipe 15
The soundproof box 16 attached around the tank can also be placed inside the tank, making it easier to achieve miniaturization.
