Description

TECHNICAL FIELD

[0001] The present application relates to a humidifier, and more particularly, to a humidifier that senses a water level using a weight sensor. BACKGROUND

[0002] A humidifier is a device that vaporizes water to discharge humidified air having a high water content.

[0003] Since a humidifier generates humidified air using water, a water tank that stores water is required. However, a user needs to know the time to supply water to the water tank by grasping the water level of the water stored in the water tank.

[0004] A method of sensing the water level of the water tank can use a float valve that moves according to the water level. In addition, the water level can be sensed by sensing the weight of the water tank.

[0005] Korean Registered Patent KR10-2505499B1 discloses a humidifier that senses a water level based on weight.

[0006] However, such a humidifier needs water not to flow into a region where the weight is measured. In addition, the water tank needs to be accurately disposed in the region where the weight is measured in order to accurately sense the water level of the water tank.

[0007] In addition, in a case where other configurations are disposed or connected between the water tank and the configuration that measures the weight, there is a problem that it can be difficult to accurately sense the weight of the water tank. SUMMARY

[0008] The present application is directed to solving the above and other problems.

[0009] Another object is to provide a humidifier that stably senses the water level of a water tank.

[0010] Still another object is to provide a humidifier that precisely senses the water level of a water tank.

[0011] Still another object is to provide a humidifier that prevents water from flowing into the inside of an intermediate tray in which a weight sensor is disposed.

[0012] To achieve the above objects, a humidifier according to an embodiment of the present application includes a water tank that forms a space to store water, and a humidification module that is disposed below the water tank and generates humidified air using water received from the water tank. The humidifier includes an intermediate tray that is disposed between the humidification module and the water tank and includes a plurality of weight sensors that sense the weight of the water tank, and an inner housing that is disposed below the water tank and transmits the load of the water tank to the intermediate tray.

[0013] A plurality of lower protrusions pressurize the plurality of weight sensors, respectively, in a lower portion of the inner case. A hole is formed in the middle tray to supply water stored in the water tank to the humidifying module. The plurality of weight sensors are spaced apart along a circumference of the hole.

[0014] A plurality of sensor grooves are formed in the middle tray to be recessed downward. The plurality of lower protrusions are disposed in the plurality of sensor grooves, respectively.

[0015] The plurality of sensor grooves each include a sensor cover that covers an upper side of a weight sensor disposed below the sensor groove.

[0016] Sensor groove flanges are protruded upward from a circumferential surface of each of the plurality of sensor grooves. The sensor cover is disposed inside the sensor groove flanges.

[0017] A cover rib is protruded inward from an inner circumferential surface of the sensor groove flanges. The sensor cover is mounted to the cover rib.

[0018] The plurality of weight sensors are spaced apart in front, back, left, and right directions with reference to the hole.

[0019] When the inner case is disposed above the middle tray, the plurality of lower protrusions are disposed above the plurality of weight sensors, respectively.

[0020] The inner case includes a fixing protrusion protruded downward to fix the disposition of the inner case. The fixing protrusion is spaced apart from the plurality of lower protrusions.

[0021] A fixing groove is formed in one side of a circumferential surface of the fixing protrusion. The middle tray includes a fixing rib that is inserted into the fixing groove.

[0022] When the fixing rib is inserted into the fixing groove, an upper end of the fixing rib is spaced apart from the inner case.

[0023] The middle tray includes a pair of fixing protrusions spaced apart from both sides of the fixing rib.

[0024] The pair of fixing protrusions each include a first inclined surface inclined toward a direction of disposition of the fixing rib.

[0025] In the inner case, an upper side of the hole includes a case through-hole.

[0026] The inner case includes a pair of first lower protrusions disposed on one side of the case through-hole and a pair of second lower protrusions disposed in an opposite direction of the pair of first lower protrusions with reference to the case through-hole.

[0027] The inner case includes a first connecting rib connecting the pair of first lower protrusions to each other, and a second connecting rib connecting the pair of second lower protrusions to each other.

[0028] The first connecting rib and the second connecting rib are each spaced apart from an upper surface of the middle tray by a predetermined interval.

[0029] The plurality of sensor grooves are each provided with a sensor cover covering an upper side of a weight sensor disposed below each of the plurality of sensor grooves. The middle tray includes a pressing body disposed between the sensor cover and the weight sensor.

[0030] The details of other embodiments are included in the detailed description and the accompanying drawings.

[0031] The humidifier according to the present application has one or more of the following effects.

[0032] First, by the structure that stably maintains the position of the water tank disposed above the middle tray, the water level of the water tank can be stably sensed.

[0033] Second, the weight sensor is disposed in a plurality of regions of the middle tray, and thus the water level of the water tank can be precisely sensed. In addition, a structure that vertically presses the middle tray is not provided in regions other than the lower protrusions, and thus the weight of the water tank can be precisely sensed.

[0034] Third, the sensor cover is disposed on the upper side of the weight sensor, and thus water can be prevented from flowing into the weight sensor. Thus, the weight sensor can stably operate.

[0035] The effects of the present application are not limited to the above-mentioned effects, and other effects not mentioned can be clearly understood by those skilled in the art from the recitation of the scope of claims. BRIEF DESCRIPTION OF DRAWINGS
