Claims

a casing having an inlet and an outlet;
air purifying filter and
a dehumidifying means having a dehumidifying section that removes moisture from the air;
a blowing means for generating airflow from the suction port to the blowout port;
indoor humidity detection means for detecting relative humidity of indoor air;
indoor air pollution level detection means for detecting an air pollution level that is a pollution level of indoor air;
a first air path through which air entering from the suction port passes through the air purifying filter, the dehumidifying section, and the blowing means, and is blown out from the air outlet;
a second air path in which air entering from the suction port passes through the dehumidifying section and the air blowing means without passing through the air purifying filter, and is blown out from the air outlet;
opening/closing means for adjusting the opening degree of the second air passage;
control means for changing the degree of opening of the opening/closing means according to the relative humidity and the degree of air pollution;
A dehumidifier equipped with

having a wind guide surface provided in the second air path,
The dehumidifier according to claim 1, wherein the air guide surface guides the air flow of the second air path so that the air flow of the second air path approaches the center of the windward side surface of the dehumidifying section.

The first air path includes a filter air path that is an air path that passes through the air purifying filter,
The second air path includes a bypass air path that does not pass through the air purifying filter,
The dehumidifier according to claim 1 or 2, wherein the bypass air path is adjacent to the filter air path.

the bypass air passage adjacent to one side of the filter air passage;
the bypass air passage adjacent to the other side of the filter air passage;
The dehumidifier according to claim 3, comprising:

The dehumidifying means is a heat pump type dehumidifying means equipped with a refrigerant circuit having a heat exchanger including an evaporator, a compressor, and a pressure reducing device, or a heat exchanger that condenses moisture in the air removed by an adsorbent. The dehumidifier according to any one of claims 1 to 4, which corresponds to a desiccant type dehumidifying means.

The degree of opening of the opening/closing means when the relative humidity is the first relative humidity and the degree of air pollution is the first degree of air pollution is compared to the degree of opening of the opening/closing means when the relative humidity is the first relative humidity and the degree of air pollution is the first degree of air pollution. The dehumidifier according to any one of claims 1 to 5, wherein the degree of opening of the opening/closing means is reduced when the degree of air pollution is a second degree of air pollution higher than the first degree of air pollution.

The degree of air pollution is the first degree of air pollution, and the degree of opening of the opening/closing means when the degree of air pollution is the first degree of air pollution and the relative humidity is the first relative humidity. The dehumidifier according to any one of claims 1 to 6, wherein the degree of opening of the opening/closing means is increased when the relative humidity is a second relative humidity higher than the first relative humidity.

Compared to the operation speed of the air blowing means when the opening degree of the opening/closing means is a first opening degree, the operation speed of the air blowing means when the opening degree of the opening/closing means is a second opening degree smaller than the first opening degree. The dehumidifier according to any one of claims 1 to 7, which has a high operating speed.

The dehumidifier according to any one of claims 1 to 8, wherein the operating speed of the air blowing means is lowered stepwise as the degree of opening of the opening/closing means increases.

The dehumidifier according to any one of claims 1 to 8, wherein the operating speed of the air blowing means is increased as the opening degree of the opening/closing means becomes smaller.
