DE2360455A1 - Vaporising humidifier with casing in three sections - has hollow tapered support feet on middle section - Google Patents

Abstract

The humidifier has an upper section which contains the air inlet and discharge grilles, a lower section which forms the water container and an intermediate section which is a carrying plate supporting all the internal components. A pump supported on the carrying plate pumps water from the container into a channel at the top of the casing from which it percolates through a vertical filter traversed by the air. The carrying plate has three or more hollow tapered supports which are longer than the longest component carried below the plate. They enable the plate to be put down when the humidifier is taken apart and also provide return flow passages for excess water from the filter.

On the three at as great a mutual distance as possible arranged water return connection is the mounting plate with great stability in exactly the same orientation as it is when installed. this will on the one hand by the larger number of water return nozzles (at least three), on the other hand by their length, which protrudes from all other parts protruding downwards from the mounting plate · This number and length of the water return connection has the advantage in terms of avoiding splashing noises that the water flowing back does not have to travel long distances on the mounting plate and from the water return connection is guided noiselessly and without splashing to just above the bottom of the water tank.

This function of noise-free discharge is advantageous thereby supported «that the water return connection at the top a large cross-section that tapers conically at the bottom to have·

Pour the water in the nozzle and it will fall straight into you the three water return pipes without being significantly distributed over the mounting plate; preferably points to this end the mounting plate in the area of the flush with the filler neck Water return nozzle to which two lateral indentations adjoin, at the end of each one of the other two water return connections is arranged.

The filler opening of the filler neck is advantageously provided with an approximately airtight closing flap, which is hinged on the side of the filling opening adjacent to the air outlet openings and folded up under about 45 ° inclined. The approximately airtight closure of the flap Is advantageous, because this way the entry of false air is avoided by the filler opening * namely it should if possible, all air sucked in by the device of the humidifier be announced through the evaporation filter and not through any other openings in the upper part of the housing. In its open position, the flap also serves as a safeguard against inadvertently poured water through the air outlet opening enters the blower

The air inlet and outlet openings are advantageous of the upper part of the housing in removable and removable Wall parts arranged. This makes manufacture and repair easier.

According to the main patent, the evaporative filter is upright standing around an approximately U-shaped frame and with its ends in hooks that are placed at the ends of the frame are hooked. This construction is advantageously improved according to the invention in that the evaporation filter is attached to the Engagement points of the hooks ring eyelets.
