Description

Technical Field

[0001] This utility model relates to the field of dehumidifier technology, specifically to a dehumidifier that can automatically drain water. Background Technology

[0002] A dehumidifier is a household appliance primarily used to regulate indoor humidity. It reduces indoor humidity by absorbing and removing excess moisture from the air. Suitable for humid environments, it effectively prevents clothes, furniture, and other items from becoming damp and moldy, while also improving living comfort and reducing health problems caused by excessive humidity, such as allergies and respiratory discomfort. Dehumidifiers are typically equipped with a water tank to collect moisture, and some models also feature intelligent control functions that automatically adjust their operating mode based on indoor humidity.

[0003] However, traditional dehumidifiers often encounter the problem of overflowing water tanks during use. This not only affects the normal operation of the dehumidifier but may also damage internal components and shorten its lifespan. Furthermore, dehumidifiers often automatically shut down when full, reducing dehumidification efficiency. To address these issues, the inventors have proposed a dehumidifier with automatic drainage to solve these problems. Utility Model Content

The end of the drain pipe 10 away from the water pump 4 extends to the outside of the body 1. A float sensor 3 is fixedly installed on the water tank 2. The float sensor 3 and the water pump 4 are electrically connected. An installation groove 7 is opened on the front side of the body 1. A filter screen plate 8 is placed inside the installation groove 7 and outside the filter screen plate 8. An air inlet screen plate 9 is placed inside the installation groove 7 and outside the filter screen plate 8. A snap-fit ​​assembly 6 is provided between the top two sides of the air inlet screen plate 9 and the body 1.

[0020] The snap-fit ​​assembly 6 includes a plate groove 61, which is opened on the outside of the air intake grille 9. A slide plate 62 is slidably snapped into the inside of the plate groove 61. A pin 63 is fixedly connected to the top of the slide plate 62. Two symmetrically distributed slots 64 are opened at the top of the inner wall of the mounting groove 7. The top of the pin 63 is movably inserted into the slot 64.

[0021] By adopting the above technical solution, the lateral movement of the air intake mesh plate 9 is limited by placing the air intake mesh plate 9 inside the mounting groove 7 and allowing the top of the pin 63 to be inserted into the slot 64, thereby protecting the filter mesh plate 8.

[0022] A guide rod 65 is fixedly connected to the bottom end of the slide plate 62. A guide groove 67 is provided inside the air intake mesh plate 9 on the side near the plate groove 61. The bottom end of the guide rod 65 is slidably engaged in the guide groove 67. A spring 66 is provided between the bottom end of the slide plate 62 and the bottom surface of the inner wall of the plate groove 61. The spring 66 is movably sleeved on the outside of the guide rod 65.

[0023] By adopting the above technical solution, the cooperation between the guide rod 65 and the guide groove 67 facilitates the vertical movement of the pin 63, improves the stability of the slide plate 62 during vertical movement, and facilitates the reset of the slide plate 62 by setting the spring 66, and makes the pin 63 more securely inserted by utilizing the elastic force of the spring 66.

[0024] A partition 11 is fixedly connected to the middle of the inner wall of the body 1. A guide groove 12 is provided on one side of the top of the partition 11. A through hole 13 is provided at one end of the inner wall of the guide groove 12. The through hole 13 communicates with the interior of the water tank 2.

[0025] By adopting the above technical solution, the water generated by the dehumidifier is guided by the guide channel 12 and flows into the water tank 2 through the through hole 13.

[0026] A PLC controller 14 is fixedly installed on the top of the machine body 1. The float sensor 3 and the water pump 4 are both electrically connected to the PLC controller 14.

[0027] By adopting the above technical solution and setting up PLC controller 14, it is easier to control the equipment to work.

[0028] Universal wheels 15 are fixedly installed at the four corners of the bottom of the body 1.

[0029] By adopting the above technical solution and setting the universal wheels 15, it is easier to move the equipment.

[0030] One end of the slide plate 62 extends to the outside of the groove 61.

[0031] By adopting the above technical solution, by extending one end of the slide plate 62 to the outside of the groove 61, it is easier to complete the unlocking operation.

[0032] Working principle: When using this dehumidifier, the water generated by the dehumidifier flows into the water tank 2 through the through hole 13 under the guidance of the guide channel 12. The float sensor 3 monitors the water level in the water tank 2. When the water level in the water tank 2 reaches the set threshold, the PLC controller 14 starts the water pump 4 to work, drawing the water in the water tank 2 out through the water inlet pipe 5 and draining it out through the drain pipe 10, thereby realizing the automatic drainage function.

[0033] When the filter plate 8 needs to be cleaned regularly, the slide plate 62 is pushed down, which simultaneously moves the guide rod 65 downward along the inside of the guide groove 67 and compresses the spring 66, causing the pin 63 to be pulled out from the inside of the slot 64. This releases the restriction on the movement of the air intake screen 9 away from the mounting groove 7, allowing the air intake screen 9 to be pulled out of the mounting groove 7. Then, the filter plate 8 is pulled out from the inside of the mounting groove 7, making it convenient to clean the filter plate 8. When installing the filter plate 8, simply place the filter plate 8 inside the mounting groove 7 and place the air intake screen 9 outside the filter plate 8, allowing the top of the pin 63 to be inserted into the inside of the slot 64, using the air intake screen 9 to limit the position of the filter plate 8.

[0034] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
