Description

Adopt the dishwasher of water under high pressure

Invention field

The present invention establishes and relates to a kind of dishwasher and wash the dish method.Especially, the present invention relates to the use that a kind of high pressure dishwasher and being used to is washed the water under high pressure of dish.

Background of invention

At present commercially available no matter the commercial still dishwasher of family expenses all utilizes chemical cleaner and hot water, and they remain on dish in shelf or the pallet, make dish be subjected to multiple cleaning and rinse cycle.The shelf or the pallet that are loaded with dish enter a chamber or pass through several chambers, and are cleaned.The water that allotment has a chemical cleaner is from top and bottom and/or sidepiece ejection, and last rinsing is normally carried out with the hot water more than 80 degrees centigrade, so that sterilize and make the dish drying.

The subject matter of the dishwasher of these types is to use a large amount of water, and will be with corresponding a large amount of chemicals and heat energy.Its reason is that water with each possible angle ejection, manages to cover whole shelf zone by a large amount of nozzles aimlessly, and dish is put again at random simultaneously, thereby can be taken place by many situations that overlap each other or cover on injection direction.Therefore, need spray and be in a plurality of nozzles on the different angles for a long time, so that give good coverage rate, thereby can be than the more water of actual needs consumption.Yet some turnings and gap usually hide mutually because of angle, the dish that sprays or can't be cleaned by the degree of depth that the shaped form profile of tableware is produced.

Another problem is that the cleaning of dishwasher and the quality of health depend on such as correct chemicals dosage and the variable the hot water temperature at present.Hot water needs 60-65 ℃ to be used for cleaning usually, and is used for rinsing more than 80 ℃.Required introducing water temperature is arranged on 40-45 ℃, and dishwasher has auxiliary (booster) heater, so that heat water to temperature required subsequently.In real life, if continue to flow from the water of water tank, then water temperature can not be guaranteed to maintain more than 40 ℃, thereby can't keep the temperature of design all the time.The method that another kind is used for the hot water health is to use chlorine, but the harm that the user will face thoroughly rinsing and remove chlorine.The deficiency of chemical cleaner dosage can cause and can not remove oil and grease clean in the clean cycle.Too much dosage does not correspondingly prolong the rinsing time again and will stay chemical pollutant on dish.Which kind of mode all can not reach cleaning and sanitary standard.

From U.S. Patent number 4,561,144 (flat dish cleaning machines, Marais), U.S. Patent number 5,846,339 (machine washing dish process, Masshoff), U.S. Patent number 5,267,580 (dishwasher and method, Payzant) and U.S. Patent number 5,667,431 (dishwasher, other is not the dishwasher design that is in daily use can to find some in Mortin).

Above-mentioned all inventions and other present dishwasher use the high flow rate low-pressure water.Cleaning is to be undertaken by add chemical cleaner extraly in hot water.Except meeting polluted to environment, they also can be unfavorable to environment aspect used energy and water source.In addition, almost present all dishwashers all need the user to strike off swill with hand earlier before putting into tableware in the dishwasher.Some dishwasher adopted the independent treatment step that strikes off before cleaning, for example U.S. Patent number 4,561, the example that strikes off with brush in 144 (the flat dish cleaning machines).Use the dishwasher of recirculation water need remove solid residue from dish usually, so that prolong the service life of filtration system.In addition, under the obviously dry situation of swill, then can't guarantee cleannes.In this case, can only forcibly soak and clean dish with hand.

Therefore, the object of the present invention is to provide a kind of dishwasher that helps environment and low energy consumption.

Summary of the invention

Therefore, one aspect of the present invention provides a kind of dishwasher that is used to clean dirty dish, tableware and vessel, and it comprises and is used for sending system by one or more nozzle ejection to the high-pressure flow water pump on the dish to be cleaned with water under high pressure.These nozzles are for example to come single direct light type nozzle of high-speed mobile by rotation or vibration.

According to another characteristics of the present invention, provide a kind of transfer system that is used to make dish remain on the appropriate location and moves through the high pressure water curtain that the direct light type nozzle by high-speed mobile produced.Cleaning process can be carried out at a high speed, is generally one to three second of each dish.This cleaning can be carried out under the situation of not using cleaning agent and hot water.

In an embodiment of the present invention, dish only by the high pressure water curtain once.Therefore, can only clean a side of dish.In order to clean another side, the user will be with being re-injected in the dishwasher with the side of not washing behind the handspring rotating disk dish.

In another kind of embodiment, dish can overturn automatically via the turning device that is arranged in the dishwasher.In such an embodiment, dish to clean an one side, enters second water under high pressure proscenia to clean its opposite flank after overturning via turning device then by the first water under high pressure proscenia.

In the above-described embodiments, each side of dish is all only cleaned once.Fully and equably impact the whole surface of dish with high-pressure flow water.Dish will be eliminated oil, grease and bacterium, reuse so that prepare against under situation about need not further clean.This can carry out under the situation that need not use cleaning agent or further rinsing.

The description of invention

As detailed below has been described the various embodiments that is used to implement cardinal principle of the present invention.Yet any those of skill in the art in the art should be understood that following description just supplies the usefulness of example of the present invention, and should not be counted as the restriction of described principle herein.In following narration and claim, term " comprises ", " having " and " comprising " is open use, thereby should be considered to be meant " comprising (but being not limited to ...) ".In addition, term " connection " or " connecting (third person odd number) " are meant indirectly or direct mechanical connects.Therefore, if first device links with second device, then this connection can be the direct mechanical connection or via the indirect mechanical connection of other device or connection.

In the following description,, many details have been enumerated out, such as the concrete parts of dishwasher in order to understand the present invention up hill and dale.In other cases, in order not make indigestion of the present invention all for naught, such as motor be used for the arrangements of electric connection of transfer system and the well-known parts the water under high pressure pumping system have just repeated no more.Any those of skill in the art in the art should be understood that, automatic dish washer is in requisition for power supply, and can be controlled by other electronic installation or the programmable device that resembles computer and so on.

At length be described now, see also accompanying drawing, Fig. 1 shows a kind of embodiment of the present invention, and wherein dish is placed on the supine conveyer belt, and dishwasher only cleans a side of dish.Single direct light type nozzle 12 that high-voltage high-speed moves is connected with the water source with high-pressure pumping system with 12a.The example of this type of nozzle be the rotary-type nozzle of injection (can buy from the market, from the United States Patent (USP) 4 of Kranzle, 989, No. 786 product) or single line oscillation mode nozzle (can buy from the market, from the product of No. 4,732,325, the United States Patent (USP) of Jensen).The end face of these nozzle alignment conveyer belts, jet angle wherein rotary-type or the oscillation mode nozzle preferably are not more than 30 degree.Nozzle 12 and 12a are set in place on a height of conveyer belt top, and their jeting area will cover the whole width of conveyer belt like this.The tableware or the pottery of the maximum that the width of the conveyer belt system that is designed to satisfy will clean.Dish 16 is shelved on the conveyer belt 17.This conveyer belt is preferably made by rubber, and has the rubber short column 18 that the surface of good friction can be provided.Dish 16 is along with the mobile of conveyer belt 17 is moved in the high-pressure injection water curtain.The velocity shock that the water jet of this high-speed mobile changes with per minute several thousand usually and is washed out any swill with the power that depends on water under high pressure pumping system on the open surfaces of dish 16.The pressure of water under high pressure and flow rate are selected to high that (usually in the scope that limbs and muscle to the mankind are harmful to) is enough to can wash out residue and bacterium, comprise the food that burns, but can not destroy the surfacing of tableware.The quantity and the basic design of nozzle in the system are depended in the calculating of pump pressure and flow rate, and can need not be determined under the situation of any improper test.For example, cover 35 centimetres of wide conveyer belts with a nozzle, it is more suitable then adopting 120 hydraulic pressure that cling to the about 12 liters flow rate of per minute.To finish identical task with two nozzles, then can adopt 80 hydraulic pressure that cling to the flow rate of 15 liters of per minutes.In a kind of example in back,, thereby can adopt low pressure because nozzle can be installed lowlyer near dish.No matter under which kind of situation, the size of nozzle is suitably made can produce required impact.For the cleaning of other type, can adopt the hydraulic pressure in the 40-80 crust scope.Also adjustable injection duration of saving in each dish.Exist the many high pressure pumpings equipment manufacturers that system can be provided to required specification.

Cutaway view shown in Figure 2 shows a kind of Rubber Conveyor Belt Scrap that can make the firm short column of dish that has.Except carrying out transmitting function, this conveyer belt 27 also can be used for absorbing the normal thrust that is produced by water under high pressure.Rubber short column 28 or other corrugated rubber surface are made into can produce great friction coefficient, in order to absorb any cross force that is produced by the high pressure water curtain.Highly different rubber short column can preferably satisfy the tableware of the different base designs with differing heights and degree of depth.The high-pressure water jet that impacts lip-deep high-speed mobile can not be created on any point of tableware is enough to the brute force that dish 26 obviously overturn or make damaged surfaces in a period of time.

Usually, the good frictional force that is produced by the short column 28 on the conveyer belt 27 that connects with dish 26 faces can prevent that any of dish 26 from laterally moving.Any those of skill in the art in the art can need not determine other design under the situation of any improper test.In certain design, as long as dish can not be offset fully, then dish 26 can be during cleaning slight inclination (but want and can be accepted).The goal pace that the optimum pressure of impacting with high pressure water and flow rate are adopted in the time of must moving dish 26 with conveyer belt 27 modestly balances each other.In order to obtain required total coverage rate, Combination Design is very important.If the speed of conveyer belt 27 is slow excessively, then dish 26 self may be difficult to enter the high pressure water curtain.If the excessive velocities of conveyer belt 27, then dish 26 can not thoroughly be cleaned.If hydraulic pressure is too high, the then corresponding reduction of flow rate, and dish 26 may be difficult to enter water curtain.Meanwhile, because of the water shortage in the water jet, thereby dish 26 can not be cleaned.If the translational speed of single direct projection stream is slow excessively, then dish 26 can not suitably be cleaned, if the translational speed of jet is too fast, then has considerable energy of flow to be wasted on the formation speed, and can not bring good effect.The worst case of dry residue on the width, dish of the maximum pottery of expection and required cleaning speed are depended in the final selection of the parameter of combined system.An example of practicable working range be used for each side washing station apart from dish 35-50 centimetre height, with the 80-150 crust of per minute 12-15 litre.

Front view shown in Figure 3 shows a kind of automatic both sides dishwasher of the both sides that are used to utilize turning device to clean dish.In this embodiment, dish 36 is at first sprayed by first group of high pressure nozzle 32.Guide the rubber dag 30 of the
