DETAILED DESCRIPTION

[0042] In the following, only some exemplary embodiments are simply described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the application. Therefore, the drawings and the description are considered to be exemplary in nature rather than limiting.

[0043] Referring to Figures 1-7 , a filter device of a preferred embodiment of the utility model is shown, comprising:

[0044] Filter 1; and

[0045] Filter seat 2, filter seat 2 supports filter 1, filter seat 2 has condensate water discharge flow channel 21 and water collecting tank 22, water collecting tank 22 is communicated with the first end of condensate water discharge flow channel 21, water collecting tank 22 is used to support the condensate water flowing down the outer side wall of filter 1 and guide the condensate water to condensate water discharge flow channel 21, and the second end of condensate water discharge flow channel 21 is used to be communicated with the water guide device outside the filtering device to discharge the condensate water outside the filtering device.

[0046] The filtering device of the utility model, through setting condensate water discharge flow channel 21 and water collecting tank 22 in filter seat 2, can utilize water collecting tank 22 to support the condensate water flowing down from the outer side wall of filter 1, that is, play the role of collecting condensate water, then utilize water collecting tank 22 to guide the collected condensate water to condensate water discharge flow channel 21, make the condensate water pass through condensate water discharge flow channel 21 and discharge to the filtering device outside, wherein, since condensate water discharge flow channel 21 and water collecting tank 22 are integratedly arranged in the structure of filter seat 2, not only the utilization rate of filter seat 2 is improved, but also the use quantity of pipeline structure outside the filtering device can be reduced, thereby reducing the cost, in addition, since the quantity of condensate water discharge pipeline structure outside the filtering device is reduced, the overall structure of the filtering device is more compact, occupies less space, and is more beneficial to the miniaturization and compactness of the ice maker.

[0047] Referring to Figures 2-4 In an embodiment, filter 1 is provided with filter main body 11 and connecting head 12, filter main body 11 and connecting head 12 are sequentially arranged along the height direction of filter 1;

[0048] Filter seat 2 has connecting groove 23, connecting groove 23 penetrates the top wall of filter seat 2, connecting groove 23 and connecting head 12 are adapted to connect filter 1 and filter seat 2 together. In this way, by inserting connecting head 12 into connecting groove 23, filter 1 and filter seat 2 can be connected together, which is simple, convenient and efficient in assembly.

[0049] In an embodiment, water collecting tank 22 is arranged around the top opening of connecting groove 23;

[0050] Condensate water discharge flow channel 21 includes:

[0051] Upstream channel section 211, upstream channel section 211 is surrounded by connecting groove 23 and connecting head 12, and upstream channel section 211 is communicated with water collecting tank 22; and

Since the upper flow channel section 211 of the condensed water discharge flow channel 21 is surrounded by the connecting groove 23 and the connecting head 12, and the water collecting groove 22 is arranged around the top opening of the connecting groove 23, the condensed water collected by the water collecting groove 22 can be concentrated and guided to the upper flow channel section 211, and then discharged after being guided to the lower flow channel section 212 through the upper flow channel section 211. Since the upper flow channel section 211 is surrounded by the connecting groove 23 and the connecting head 12, it is not necessary to additionally open a flow channel structure at other parts of the filter seat 2, but only to open the lower flow channel section 212 at the part of the filter seat 2 located below the connecting groove 23, thereby simplifying the manufacturing process of the condensed water discharge flow channel 21, reducing the manufacturing difficulty of the condensed water discharge flow channel 21, and further reducing the cost of the filter device. In addition, since the condensed water discharge flow channel 21 is composed of the upper flow channel section 211 and the lower flow channel section 212 arranged in sequence along the water flow direction, the condensed water can be smoothly drained by using its own gravity during the water discharge process, without the need for additional power components, to ensure smooth water discharge, so that the condensed water discharge flow channel 21 will not accumulate water, and at the same time, the structure is simplified, which is beneficial to further reduce the cost of the filter device.

In this way, when the connecting head 12 is inserted into the connecting groove 23, the bottom wall of the connecting groove 23 and the connecting head 12 are isolated by the plurality of isolation protrusions 24 and the end of the connecting head 12 away from the filter 1, so that the communication flow channel 213 surrounded by the isolation protrusion 24 and the bottom wall of the connecting groove 23 can communicate the upper flow channel section 211 and the lower flow channel section 212, thereby ensuring that the condensed water can be smoothly discharged.

[0056] Referring to Figure 4 and Figure 5 In an embodiment, the filter body 11 has a filter cavity 111, the connecting head 12 has a first water flow channel 121 and a water flow valve 13, the water flow valve 13 is arranged in the first water flow channel 121, and the water flow valve 13 has an open state and a closed state, the open state is that the first water flow channel 121 is in communication with the filter cavity 111, and the closed state is that the first water flow channel 121 is interrupted in communication with the filter cavity 111.

[0058] In the case that the connecting head 12 and the connecting groove 23 are matched, the top rod 25 is inserted into the first water flow channel 121, and the top rod 25 and the water flow valve 13 abut to switch the water flow valve 13 from the closed state to the open state, so as to make the second water flow channel 26 in communication with the first water flow channel 121. It can be understood that in actual application, the first water flow channel 121 and the second water flow channel 26 form a water flow channel structure, the number of the water flow channel structure is at least two groups, one group of the water flow channel structure is an inlet water flow channel structure, and the other group of the water flow channel structure is an outlet water flow channel structure, in the case that the inlet water flow channel structure is in communication with an external water supply device at an inlet water end, water source can be supplied to the filter cavity 111, and in the case that the outlet water flow channel structure is in communication with an external water using device at an outlet water end, purified water made by the filter 1 can be supplied to the water using device.

[0062] Referring to Figure 2In an embodiment, the side wall of the connecting groove 23 is provided with a limiting groove 29, which is arranged around the vertical center line of the connecting groove 23;

[0063] The outer peripheral wall of the connecting head 12 is provided with a limiting protrusion 14, which has a first state and a second state.
