Description

Winter outdoor warm water slow-dripping anti-freezing technology for self-service car washer

Technical Field

The invention relates to the technical field of self-service car washing machines, in particular to an outdoor winter anti-freezing technology for a pipeline of a self-service car washing machine.

Background

With the rapid increase of the automobile holding capacity and the rapid rise of the labor cost in China, self-service automobile washing has become a very popular automobile washing mode for people. The self-service car washer is not very long in rapid development time in China, but is developed very rapidly in recent years, and the self-service car washer is not only in domestic layout, but also begins to export abroad.

The self-service car washing machine is mainly put into places such as indoor places or underground garages or places for stopping business in winter. The anti-freezing technology in winter seriously restricts the development of the self-service car washing industry in the areas frozen in winter, and simultaneously influences the export potential of equipment in Europe, Russia and other areas.

The technology of preventing frostbite in winter on the existing market mainly adopts in the rack to add heat preservation and hot plate, and the mode of the water gravity evacuation in outside high-pressure pipe and the squirt carries out preventing frostbite of outside pipeline, but this kind of technique is because moisture is difficult to the evacuation completely in the outside pipeline, and in northeast severe cold district, because the temperature is very low, often the evacuation that varies freezes promptly, blocks up outside high-pressure pipeline. Meanwhile, the external pipeline belongs to a high-pressure pipeline and relates to a high-pressure nozzle of the water gun, the caliber of the high-pressure nozzle is usually only about 1 millimeter, and the water gun can be frozen and blocked only by retaining a drop of water, so that the water gun cannot be used. Also some equipment adopt the pipeline to retrieve to keep warm in the box and prevent frostbite, but self-service car washing unmanned on duty's characteristics cause often some customers not retrieve the return with the pipeline and cause freezing and bad. Therefore, the anti-freezing technology for outdoor putting of the self-service car washing machine which can be widely used and can be suitable for the high and cold areas in winter is very necessary, and the market in areas such as Europe, Russia and the like can be opened, so that the market range is effectively expanded.

Disclosure of Invention

The invention aims to provide a winter outdoor warm water slow-dripping anti-freezing technology for a self-service car washer.

As shown in fig. 1, an anti-freezing device comprises a tee joint (1), a heater (4), an electromagnetic valve (3), a tee joint (2), a high-pressure water pump (5) and a high-pressure water gun (6) without a trigger device;

the tee joint (1) is positioned at a water inlet end, divides water flow into two paths, one path of water flow is led to the electromagnetic valve (3), the other path of water flow is led to the heater (4), then the two paths of water flow are connected to the tee joint (2) again, are converged and flow into the high-pressure water pump (5), are pressurized by the high-pressure water pump (5), and are conveyed to the high-pressure water gun (6) of the trigger-free device;

as shown in fig. 3, the heater (4) is composed of a heating chamber (7), a water inlet (8), a water outlet (9) and an electric heating tube (10), the heating chamber (7) is used for storing water flow for heating, the water outlet (9) with a small diameter is used for slowing down the water flow, and the flow is reduced so that the water flow can stay in the heating chamber (7) for a period of time to raise the temperature.

According to the anti-freezing principle of the method, when the high-pressure water pump (5) works, the electromagnetic valve (3) is synchronously opened, large-flow normal-temperature water flow is supplied to the high-pressure water pump (5) through the electromagnetic valve, and is directly conveyed to the high-pressure water gun (6) without a trigger device to be sprayed out after being pressurized by the high-pressure water pump (5); when high pressure water pump (5) stop work, solenoid valve (3) are closed in step, and rivers can only flow to heater (4), because the play water end bore of heater (4) is very little, consequently rivers are heated in heater (4), and the warm water after the heating slowly flows out through the small-bore apopore of heater (4), gets into high pressure water pump (5) through tee bend (2) and flows at last to no trigger device high pressure squirt (6) and drips out from the high pressure nozzle of squirt. The core of the invention is that warm water flowing from the whole pipeline to the spray hole of the nozzle of the water gun (6) is provided when the pipeline is in standby, so that the temperature of the whole pipeline including the nozzle of the water gun exposed in outdoor cold air is always kept above 0 ℃ and can not be frozen, thereby realizing the simple and low-cost anti-freezing effect.

Optionally, as a further technical solution, the tee joint (1) in the embodiment shown in fig. 1 may also be a two-position tee joint electromagnetic valve, instead of the tee joint (1) and the electromagnetic valve (3), when the high-pressure water pump (5) works, a valve directly supplying one way of the high-pressure water pump is opened, when the high-pressure water pump does not work, the valve leading to the one way of the high-pressure water pump (5) is closed, and simultaneously, the valve leading to the one way of the heater (4) is opened, and the effect is equivalent to that of the apparatus in the embodiment shown in fig. 1.

Optionally, as a further technical scheme, a thermostatic controller can be added to the heater to accurately control the water temperature, a flow restrictor or a peristaltic pump is arranged in the middle of the hot water flowing from the heater to the tee joint (2), and the flow speed and flow of the hot water are accurately controlled through electronic adjustment, so that the implementation of the method is more intelligent.

Optionally, as further technical scheme, need whole journey hot water carwash in severe cold district, the heater also can be installed on the storage water tank of self-service car washer, realize heating and keeping warm to the storage water tank, the storage water tank is two way delivery ports, install the solenoid valve directly and supply high pressure water pump additional all the way, another way then control flow supplies high pressure water pump, when realizing that the water pump is out of work, the continuous slow water supply of warm water in the storage water tank is to water pump, squirt and from the high pressure nozzle of squirt drippage, and then reach the effect of preventing and curing freezing.

It should be noted that the above schemes and embodiments, as well as the illustrations, are exemplary and are intended to provide further explanation of the present application. Unless otherwise defined, all techniques and terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs.

The invention has the advantages that the outdoor anti-freezing problem of the self-service car washer is realized by using a simple structure, particularly, after intelligent temperature control and water flow regulation are added, the water temperature and the flow rate can be accurately regulated and controlled according to the outdoor temperature, the self-service car washer can be better suitable for severe cold areas such as northeast, russia, northern Europe and the like, and the aim of putting the self-service car washer outdoors in the north, particularly in the severe cold areas, for preventing freezing is realized.
