Abstract

A dehumidifier with multistage draining has a container 30 that collects and stores condensed water from a dehumidifying assembly 20. Mounted within the container is a float (40 fig 2) connected to an associated actuator 50. The dehumidifier also includes a drain motor (pump) 60 and an attachment actuator 70 having a switch (711 fig 8). The attachment actuator has a connector (76 fig 8) for receiving an external pipe, which when connected operates the attachment actuator switch. When in use, the condensed water in the container gradually increases causing the float to switch on the float actuator. If a pipe is connected to the attachment actuator so that both the float actuator and the attachment actuator are both switched, then the drain motor will start to pump the condensed water out of the container. This permits the dehumidifier to automatically drain condensed water from the container according to the quantity of condensed water and the connection state of the attachment actuator. The dehumidifier also includes a water storage tank 80 and an associated collection tube 34 which connects the container to the water storage tank for additional drainage in the event of drain motor failure or power loss.

Description

DEHUMIDIFIER WITH MULTISTAGE DRAINING
1. Field of the Invention
The present invention relates to a dehumidifier, especially to a dehumidifier with multistage draining for condensing gaseous water in the air into condensed water to lower humidity of the surroundings.
2. Description of the Prior Arts
A dehumidifier is a common electric appliance that regulates indoor humidity. The dehumidifier sucks and cools humid air to condense gaseous water in the humid air into condensed water and therefore to separate the humid air into dry air and condensed water. Then the dehumidifier heats and exhausts the dry air out of the dehumidifier. Therefore the humidity of the surroundings is lowered and the surroundings become comfortable. Dehumidifiers may also be implemented to protect buildings to dry out walls after flooding or the like.
A conventional dehumidifier has a container that stores condensed water.
When the container is filled with condensed water, the conventional dehumidifier signals an alarm to allow people to clear the condensed water from inside the container or the conventional dehumidifier will automatically shot off due to a safety device inside the conventional dehumidifier.
However, the conventional dehumidifier is inconvenient. When the surroundings remains humid, the container should be cleared frequently or requires a bigger container to allow the conventional dehumidifier to remain operational. When the container is removed for emptying, the dehumidifier will also cease operation, lowering efficiency. Moreover, the dehumidifier must be monitored, so when left running at night, the dehumidifier may fill and cease * 2 operation and this may increase damage to buildings or cause discomfort.
The main objective of the present invention is to provide a dehumidifier with multistage draining that has a dehumidifying assembly, a container, a float being mounted in the container, a float actuator being connected to the float, an attachment actuator and a drain motor being electrically connected to the float actuator and the attachment actuator. The container collects and stores condensed water from the dehumidifying assembly. The attachment actuator has a switch.
When an external pipe is connected to the attachment connector to actuate the switch and the condensed water in the container raises the float to actuate the float actuator, the drain motor is switched on to pump the condensed water out of the container. The dehumidifier automatically drains the condensed water in the container according to the quantity of the condensed water.
Therefore, the dehumidifier does not have to be cleared frequently and is convenient.

The button (762) corresponds to and is mounted in the Y-shaped recess (713) of the mounting cover (71) and selectively presses against the switch (711) of the mounting cover (71). S 10
The drain motor (60) is mounted in the housing (10), is electrically connected to the terminals (52) of the float actuator (50) and the switch (711) of the attachment actuator (70), is selectively switched on when the float actuator (50) and the switch (711) of the attachment actuator (70) are switched on and may be selectively switched on when the terminals (52) of the float actuator (50) are connected to the annular connector (54) of the float actuator (50) and the button (762) of the attachment connector (76) press against the switch (711) of the mounting cover (71).
The drain pipe (38) is connected to the drain hole (37) of the container (30) and the drain motor (60).
The connecting pipe (39) is connected to the drain motor (60) and the attachment actuator (70) and may be connected to the inner open end of the restore assembly (72) of the attachment actuator (70).
When the drain motor (60) is switched on, the condensed water that is collected in the container (30) flows through the drain pipe (38), the drain motor (60), the connecting pipe (39) and the attachment actuator (70) to flows out of the dehumidifier as described.
The water-storage tank (80) is mounted in the housing (10) and communicates with the collecting tube (34) of the container (30).
With reference to Figs. 2 and 7, when there is no condensed water in the container (30), the float (40) and the distal end of the connecting rod (55) of the float actuator (50) move down toward the front bottom of the container (30).
Consequently, the driving connector (53) of the float actuator (50) and the elastic positioning protrusions (543) of the annular connector (54) that engage the mounting recesses (531) of the driving connector (53) are pulled down.
Therefore, the annular connector (54) is bent and the conducting protrusions (542) of the annular connector (54) disconnect from the conducting protrusions (521) of the terminals (52). The float actuator (50) is switched off.
With reference to Fig. 9, when the spring (721) of the restore assembly (72) pushes the stopper (722), the stopper (722) seals the tubular restore assembly (72) and pushes the restore assembly (72) outwardly to allow the button (762) of the attachment connector (76) to move away from the switch (711) of the mounting cover (71) of the attachment actuator (70). Therefore, the switch (711) of the mounting cover (71) of the attachment actuator (70) is off.
Thus, the drain motor (60) is switched off while the float actuator (50) and the switch (711) of the mounting cover (71) of the attachment actuator (70) are switched off.
With further reference to Figs. 3 and 10, as the condensed water from the dehumidifying assembly (20) is gradually collected in and stored in the container (30), the float (40) and the distal end of the driving connector (53) of the float actuator (50) rise corresponding to a level of the condensed water. Once enough condensed water is held by the container (30) the driving connector (53) of the float actuator (50) rises high enough to push the elastic positioning protrusions (543) of the annular connector (54), the annular connector (54) is elastically inverted. Therefore, the conducting protrusions (542) of the annular connector (54) connect the conducting protrusions (521) of the terminals (52). The float actuator (50) is switched on.
With further reference to Fig. 11, when an external pipe is connected to the connecting tube (761) of the attachment connector (76) and pushes the attachment connector (76), the attachment connector (76) further pushes the positioning cover (75). Therefore, the button (762) of the attachment connector (76) presses against and switches on the switch (711) of the mounting cover (71).
Furthermore, the spring (721) of the restore assembly (72) is compressed and the pins (732) of the middle assembly (73) are mounted into the annular recess (764) of the attachment connector (76) to lock the attachment connector (76) in a specific position.
Thus, the drain motor (60) is switched on when both the float actuator (50) and the switch (711) of the mounting cover (71) of the attachment actuator (70) are switched on. Therefore, the condensed water stored in the container (30) is pumped out of the container (30), flows through the drain pipe (38), the connecting pipe (39), the restore assembly (72) and the connecting tube (761) of the attachment connector (76) and then is drained out of the dehumidifier as described.
As long as the condensed water gradually flows out of the container (30), the float (40) and the distal end of the connecting rod (55) of the float actuator (50) move down toward the front bottom of the container (30). However, the conducting protrusions (542) of the annular connector (54) remain connected to the conducting protrusions (521) of the terminals (52) because of the elasticity of the annular connector (54). Therefore, the drain motor (60) keeps pumping the condensed water out of the container (30) and the connecting rod (55) keeps pulling the elastic positioning protrusions (543) of the annular connector (54).
Once the annular connector (54) is inverted again and the conducting protrusions (542) of the annular connector (54) disconnect from the conducting protrusions (521) of the terminals (52) the drain motor (60) is switched off.
Consequently, with the elasticity of the annular connector (54) of the float actuator (50), the drain motor (60) will stop working after operating over a specific time and pumping a specific quantity of water out of the container (60).
Moreover, the positioning cover (75) can be pushed to move the sustaining assembly (74) to allow the annular shoulder (741) of the sustaining assembly (74) to push the pins (732) of the middle assembly (73). Thus, the pins (732) respectively move along the corresponding arc recesses (731) of the middle assembly (73) and out of the annular recess (764) of the switch connector (76). At this moment, with the spring (721) of the restore assembly (72) push the stopper (722) and the attachment connector (76) and the springs (733) of the middle assembly (73) pushing the pins (732) of the middle assembly (73), the button (762) of the attachment connector (76) is moved away from the switch (711) of the mounting cover (71). Therefore, the drain motor (60) is switched off.
Consequently, the drain motor (60) can be switched off by pressing the attachment actuator (70).
In addition, when the condensed water in the container (30) gets more and more and is higher than the inner open end of the collecting tube (34) of the container (30), the condensed water will flows through the collecting tube (34) and into the water-storage tank (80). Therefore, even though the electric power is cut or the drain motor (60) breaks down, the condensed water in the container (30) can still be drained out of the container (30).
The dehumidifier as described has the following advantages. The drain * 14 motor (60) is switched on to drain the condensed water in the container (30) when the float actuator (50) and the attachment actuator (70) are switched on at the same time. The dehumidifier as described automatically drains the condensed water in the container (30) according to the quantity of the condensed water in the container (30). Therefore, the dehumidifier does not have to be cleared frequently and is convenient. S 15
