I would assume there is there a pump that recirculates the w

No there isn't!!! I had no idea about how this machine worked until now. This is a very interesting machine, according to the patent:

"By maintaining a predetermine liquid level in the bottom of the tub during the discharge of liquid under pressure though the unions (#46) I am able to continuously recirculate the detergent-containing water liquid in the bottom of the tub through the partially submerged aspirator passageways in the discharge unions (#47)."

Correct me if I'm wrong Lou, but what I take from that description is detergent is placed into the wash tub with the dishes. The basket sits on a strong bearing and is easily turned (see my color illustration below). The water is turned on and sprayed onto the dishes out of the blue jets causing the dish rack to turn. Once the water level reaches up and covers the red part of the jets the detergent laden water is sucked into the aspirators and mixed and sprayed with the never ending fresh incoming water. During the first few minutes of wash (after the water level reaches up to the red aspirators) the water is heavily detergent laden, but after seven or eight minutes the detergent laden water has now become very diluted with fresh water to the point that the dishes are slowly but surely rinsed.

The knob on the left controls the water through the spray. The knob in the center opens and closes the drain which is similar to a bathroom sink basin drain with an overflow opening at the top. The knob on the right seems to control a hydraulic lift to lift the dish rack upwards. According to the patent:

"During the elevation of the shaft (that holds the dish rack), the anti friction bearing member permits any angular momentum of the dish container and its contents to continue the rotational movement of the container for a substantial period of timer after the rack has been elevated to its fully raised position so as to dry the contents thereof by inducing the movement of air around the articles therein having surfaces exposed to contact with the atmosphere.

Very fun! Another machine like Frigidaire, Apex or ABC who's design is one that stands out from the crowd.

Oh I forgot to mention that the green pipe is the drain pipe, since fresh water is constantly entering the machine once it reaches to the top of the aspirators (red) it needs to be bled off and sent down the drain.

Very cool! I'd never heard of the Kaiser dishwasher. Thanks for the pics and explanations. Always fun to see machines with unique engineering.

answer for robert

as the machine fills it increases the force of the water several times than the pressure that is coming in from main house supply within four minutes the water level reachs the overflo, then i open drain valve you can tell by sound of the tub is empty as you hear it trying to suck the water up,for good washing n rinsing the drain valve must be close to increaese the water pressure when the valve is close it also controls the speed of basket by slowing it down a bit ,i leave valve open beginning of cycle for prerinse an rasing the temp. of dishs an tub for obout a minute at this time the basket spins very fast,then close valve an you start to hear the suction of water jets an basket starts to slow down a bit at that time I add the detergent threw the dispenser at the top of the lid after four minutes I open drain n close again for first rinse n again same process for second rinse than I ad jet dry threw the same disp. for two minutes an shut water off first than drain an open lid right away an the basket spin for to more minutes on its own ,when it stops dishs are almost dry carl from the kaiser fraser car club is going to make me a copy of the use n care book I had no book when igot the machine it took me a wlile to understand the concept of this machine an how it worked but its been fun an I love this dishwasher I also love your youngstown dishwasher would love to get my paws on one of those im going to try to make a video but first I have to kidknap a ten year old to show me how its hard teaching an old dog new tricks lol! thank god for peter because he post all the pictures for me well hope this helped you , lou

I wonder exactly how those aspirators under the spray nozzles do that??? It must have something to do with the physics of the fresh incoming water rushing past those holes.

Hey Robert....Now you just going to have to get one of these. I can see the intrigue in your posts. I can just see it in your kitchen...

Good Luck

WAY KEWL MACHINE!

What must be happening is an increase of velocity not pressure. It looks or sounds like pressure increase but its velocity increase. Pressure is related to energy in, something has to do work to generate a pressure.

This Kaiser works on the Bernoulli Principal just like an airplane, wind over the top of the wing has to travel farther than under the wing so it must speed up and spread out thereby causing a "vacuum" ( lower pressure) to form ,sucking the wing up to the sky gods.

If you add up all the pressures & volumes of water from the nozzles it must equal the incoming pressure and volume from the source.

But the plenum water & detergent being sucked up the jets is the Venturi principal just like in all Auto Carburetors. (Which is also the Bernoulli Princp.) Moving air ( water in this case) draws fuel out from the Carb float and in the Kaiser water rushing up the jet draws in water & soap in the plenum.

The link below explains it better and you can see water being sucked up in the photo on the right.

modern version?

I wonder if a modern version of this could be made. Say, add a recirculating pump, filter, and heating element of some kind. I think that'd be cool. It'd offer you more advanced features but still completely manual control.
