A filter assembly structure comprising:
- a filter housing configured to be coupled to an inner surface of a base panel provided in a case of a water heater, and including a flow space formed together with the inner surface of the base panel and an entrance to communicate with the flow space;
- a filter assembly detachably assembled with the filter housing and including an air filter to filter air introduced through an air inlet provided in the base panel;
- and
- a first packing member having a shape of a closed loop to seal between an end portion of a flange part of the filter housing and the inner surface of the base panel,
- wherein the filter assembly is configured to be inserted into or separated from the filter housing through the entrance in a sliding manner and is provided so as to be overlapped with the air inlet when it is viewed along a direction in which the air inlet penetrates the base panel, and
- wherein the flange part has shape of a closed loop perpendicular to the air inlet,
- wherein the filter housing includes a first opening to supply the air, which is introduced into the flow space through the air inlet, to a supply space, when a space, which is provided outside the flow space, in an inner space of the case is referred to as the supply space,
- wherein the filter assembly includes:
- a cover member having a second opening formed to communicate with the first opening;
- and
- a filter member including the air filter, and a fixing frame which is to fix the air filter and detachably assembled to the cover member,
- wherein the cover member includes:
- a cover body having the second opening and provided to make contact with the bottom plate;
- and
- a rear wall part extending toward the base panel at a distal end portion of the cover body;
- and
- wherein the cover member further includes:
- a gripping groove formed to be recessed in the rear wall part;
- and
- cut-out parts formed to be recessed in the cover body.

- wherein the filter assembly is configured to be inserted into the filter housing or separated from the filter housing through the entrance in a sliding manner and is provided so as to be overlapped with the air inlet when it is viewed along a direction in which the air inlet penetrates the base panel, and
- wherein the flange part has shape of a closed loop perpendicular to the air inlet, and
- wherein the filter housing includes a first opening to supply the air, which is introduced into the flow space through the air inlet, to a supply space, when a space, which is provided outside the flow space, in an inner space of the case is referred to as the supply space, and
- wherein the filter assembly includes:
- a cover member having a second opening formed to communicate with the first opening;
- and
- a filter member including the air filter, and a fixing frame which is to fix the air filter and detachably assembled to the cover member, and
- wherein the cover member includes:
- a cover body having the second opening and provided to make contact with the bottom plate;
- and
- a rear wall part extending toward the base panel at a distal end portion of the cover body;
- and
- wherein the cover member includes:
- a gripping groove formed to be recessed in the rear wall part;
- and
- cut-out parts formed to be recessed in the cover body.
