JPS59212635A - Drain system for unit type steam humidifier - Google Patents

Abstract

PURPOSE:To provide a humidifier with a scale-free drain system, by arranging it such that a drain hole is formed through the bottom of steam cylinder containing an evaporating water therein, while an inverse U-shaped drain pipe is connected with the top end of drain hole and a pump is provided at an intermediate position of the drain pipe. CONSTITUTION:Upon a water supplying solenoid 27 being opened for supplying an evaporating water into a steam cylinder 21, a water level in a cylinder rises simultaneously with the rise of water level 28b in a drain pipe 28. When the water level rises sufficiently to get into contact with plate electrodes 22-24, a power source 34 is actuated to evaporate the water into steam which is then led from a steam exhaust port to a desired place. Upon the water level exceeding the bent portion 28a of drain pipe 28, the water is drained out through the drain pipe 28 and the steam cylinder can therefore restrict its water level at a specific level. A large clearance formed between the top end of blade 29b and the inner wall of pump cover inside a drain pump serves to prevent the clogging caused by scale and the like.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] The present invention relates to a drainage system for a Unit No. 11J steam humidifier used in a constant temperature and humidity chamber or the like.

C Background of the Invention] In recent years, constant temperature i'! +i!

FIG. 1 is a diagram showing an example of a conventional unit type steam heater. A heater 2 for heating water is installed in a steam cylinder l containing water for evaporation. Put water for evaporation into the heater 2 (heater 2 (two-part heat current) and heat it by 11 hours, /l(l'

7) The steam from the steam outlet is sent to the destination from the steam outlet 1. Water is discharged from the steam cylinder 1 through the drain pipe 8 by opening the drain solenoid valve 7.

1] Figure 1 shows the unit-type steam heating system that was introduced in the 19th century.
In vessel C, since the III water pump 8 is installed in the middle part of the steam cylinder L rather than at the bottom, there is less worry that the drain solenoid valve will be clogged by the scale tray, but most of the scale 1 will accumulate at the bottom of the steam cylinder. Therefore, there is a drawback that a large number of 111j intervals are required to remove this. Furthermore, if a drain port is provided at the bottom of the steam cylinder 1 as shown in FIG. If the mesh 12a is made finer, there is a drawback that there is a greater possibility that the strainer 12 will become clogged or that scale 1] will accumulate. Furthermore, the conventional UNINOTONO 1. shown in FIGS. 1 and 2. All of the Pal Kika i! u! devices have a disadvantage in that when the hand water tank 4 is installed, it is necessary to prevent overflow by using an overflow pipe 14, which makes the construction of the water tank complicated.

[January Aspect of the Invention] The present invention has been made in view of the above-mentioned points, and includes providing a drainage pipe 1 at the bottom of the steam cylinder, and a drainage pipe provided at the tip of this drainage port (- a drainage pump). It has a simple structure that only needs to be installed, there is no need to make the strainer mensch finer, and there is less possibility of the scale θ) breaking.

Figure 4 shows the unit type steam IJII with a small structure.
i'! u! When the water supply solenoid valve 27 is opened and water for evaporation is supplied to the steam cylinder 2, the water in the steam cylinder 2 is +11 and at the same time, the water in the drain pipe 28 is 0) water (>728 t+ also rises.The water level in the steam cylinder is 11 poles 22-24. The water level has reached 2 parts i')''l'+ W+: Plate electrodes 22 to 24 from tip 34 (1 heating current to 11Q '1
jj. Since the plate electrodes 22 to 24 have wide surfaces, the current begins to flow immediately and reaches the specified depth 111r.
When the value is reached, the water supply electromagnetic valve 27 is closed and steam is generated, and this steam is sent to a location 1-1 from the steam exhaust L]λ5.

A water sensing circuit (not shown) monitors the water quality inside the evaporation cylinder (Q), and when the water quality concentration reaches a specified value or less, the motor 30 is started, and the water inside the steam cylinder 2 is passed through the drainage pipe 28 for a certain period of time ( several seconds). When the water level in the steam cylinder 21 falls, the water supply solenoid valve 27 is opened and water is supplied into the steam cylinder 2. At this time, if the water level reaches the limit, the water level in the drain pipe 28 will also rise at the same time, so if the water level 28b exceeds the bending point 28a of the drain pipe 2B, the water will fall down the drain pipe 28 (・The water will be drained, and the water level in the steam cylinder will be constant IJ, 1-.
