Abstract

A dehumidifier includes a housing having a mounting groove, a water tank detachably inserted in the mounting groove and including an abutment member, a pump assembly including a water pump and a water pump inlet pipe, a water tank outlet pipe, and a micro switch installed at the housing. A first end of the water pump inlet pipe is connected to the water pump. A first end of the water tank outlet pipe is detachably connected to a second end of the water pump inlet pipe. A second end of the water tank outlet pipe is located in the water tank. When the water tank is installed in place, the micro switch is pressed by the abutment member to connect the water pump to a power supply, and the water pump inlet pipe is communicated with the water tank outlet pipe.

First claim

What is claimed is:

1. A dehumidifier comprising:
a housing having a mounting groove;
a water tank detachably inserted in the mounting groove and including an abutment member and a bracket;
a pump assembly including a water pump and a water pump inlet pipe, a first end of the water pump inlet pipe being connected to the water pump;
a water tank outlet pipe, a first end of the water tank outlet pipe being detachably connected to a second end of the water pump inlet pipe, and a second end of the water tank outlet pipe being located in the water tank; and
a micro switch installed at the housing;
wherein when the water tank is installed in place, the micro switch is pressed by the abutment member to connect the water pump to a power supply, and the water pump inlet pipe is communicated with the water tank outlet pipe; and
wherein the bracket is connected to the water tank outlet pipe.

2. The dehumidifier of claim 1 , wherein:
a tank body of the water tank includes a front plate and a back plate opposite to the front plate; and
the bracket is connected to the back plate.

3. The dehumidifier of claim 2 , wherein the abutment member includes an abutment protrusion formed at the bracket, located at an outer side of the water tank, and extending away from the front plate.

4. The dehumidifier of claim 3 , wherein:
the housing further includes a partition plate forming a bottom of the mounting groove, an accommodation cavity being formed at a side of the partition plate away from the mounting groove;
the partition plate is provided with an alignment hole communicating with the mounting groove and the accommodation cavity;
the micro switch is located in the accommodation cavity and faces the alignment hole; and
the abutment protrusion is movably disposed through the alignment hole to abut against the micro switch.

5. The dehumidifier of claim 4 , wherein:
the bracket includes a first adapter connected to the first end of the water tank outlet pipe;
the partition plate includes a second adapter communicating with the mounting groove and connected to the second end of the water pump inlet pipe; and
the first adapter is detachably plugged to the second adapter.

6. The dehumidifier of claim 5 , wherein:
the bracket further includes a bracket body including the abutment protrusion and connected to the back plate;
a top of the bracket body includes a mounting protrusion and a first bolt arranged at an interval, the mounting protrusion having a limiting hole facing the first bolt; and
the first adapter includes:
a limiting protrusion adapted to the alignment hole; and
a second bolt adapted to the first bolt.

7. The dehumidifier of claim 1 , wherein the bracket is detachably connected to a tank body of the water tank.

8. The dehumidifier of claim 7 , wherein the bracket is buckled to the tank body of the water tank.

9. The dehumidifier of claim 7 , wherein the bracket includes a mounting end extending into the water tank and including a filter, the second end of the water tank outlet pipe being communicated with the filter.

10. The dehumidifier of claim 9 , wherein:
the water tank outlet pipe includes a hose;
the mounting end of the bracket includes a mounting pipe;
the filter is provided at an inlet end of the mounting pipe; and
the second end of the water tank outlet pipe is connected to an outlet end of the mounting pipe.

11. The dehumidifier of claim 10 , wherein:
an inlet of the mounting pipe is trumpet-shaped, and a radius of the outlet end of the mounting pipe is smaller than a radius of the inlet end of the mounting pipe.

12. The dehumidifier of claim 1 , wherein:
the micro switch includes an elastic trigger plate; and
the micro switch has:
a first state in which the abutment member abuts against the elastic trigger plate to open the micro switch, and
a second state in which the elastic trigger plate is reset and the micro switch is closed.

13. The dehumidifier of claim 1 , wherein the water pump is located inside the housing and connected to the housing.
