The present invention relates to a stroller.

In general, strollers are widely used in most households as essential supplies for infants under 5 years of age or in child care.

 In particular, when a baby is traveling outdoors or out of the house with a baby, the baby carriage is widely used as a means for moving an infant. In addition, the stroller is a device that carries and transports the infant, so that the safety of the infant should be ensured first and the use of the companion should be simplified. Therefore, the baby stroller has been developed in the configuration considering safety of the infant and the configuration considering the convenience of the companion.

There is a system in which a baby stroller simply serves to carry and move infants and does not have a system that optimally adjusts the air quality or temperature inside a boarding space on which the infant is being carried to an infant, thereby exposing infants to cold or fine dust do.

In addition, in the past, the caregiver of infants and toddlers has no knowledge of the state of the inside of the baby carriage, and thus there is a problem that care for infants and toddlers can not be preemptively performed.

The problem to be solved by the present invention is to provide clean air and comfortable internal temperature to infants on a stroller.

In order to achieve the above object, the present invention provides an air purifier that forms a receiving space for accommodating infants and an outside air inlet to the stroller body, .

Further, the present invention is characterized in that the filter outlet is communicated with the air flow passage, and the filter outlet is formed in and out of the filter unit, and the filter can be replaced through the filter outlet.

In addition, the present invention provides an air conditioner comprising: an air quality sensor for sensing air quality in the accommodation space; a temperature sensor for sensing the temperature of air in the accommodation space; a recognition sensor for sensing infants in the accommodation space; The control unit may further include a control unit.

According to the refrigerator of the present invention, one or more of the following effects can be obtained.

According to the present invention, there is an advantage that the infant can safely be carried and the pleasant surrounding environment can be provided to the infant.

When the filter unit needs to be replaced, the protector removes the filter body coupled to the filter door without removing the baby carriage, replaces the filter unit in the filter body, and inserts the filter body into the filter doorway again to easily replace the consumable filter unit .

The protector can know the state of the infant and the inside of the accommodation space through the terminal, and can control the temperature and the air quality in the accommodation space by inputting a control command to the terminal.

FIG. 3 is a cross-sectional view taken along line A-A of the baby carriage body 100 according to an embodiment of the present invention, and FIG. 4 is a cross-sectional view taken along line B-B of the baby carriage body 100 according to an embodiment of the present invention.

3 and 4, the baby carriage body 100 of the present invention may include an outer casing 110 and an inner casing 120. [

The baby carriage body 100 includes an outer casing 110 formed with a doorway 102 at one side thereof and defining an outer appearance of the baby carriage body 100 and an inner casing 110 partitioning the inner space of the casing into the accommodation space 104 and the air- And may include a casing 120.

The outer casing 110 is in the form of a sphere having an entrance 102 at one side and forms an outer appearance of the baby carriage body.

The inner casing 120 divides the inner space of the casing into the accommodation space 104 and the air purification space. The inner casing 120 is arranged so as to face the entrance 102 so that the upper space of the inner casing 120 becomes the accommodation space 104 and the space between the lower portion of the inner casing 120 and the outer casing 110 becomes air It is defined as a purification space.

The outer casing 110 and the inner casing 120 are made of high-strength synthetic resin and carbon fiber. At this time, a seat 125 is provided on the inner surface of the accommodation space 104 to provide a smooth ride feeling to the infant in the accommodation space 104.

The seat 125 is made of a material that is softer than the outer casing 110 and the inner casing 120. Preferably, the sheet may be made of rubber, foamed resin, cloth or the like.

The baby carriage body 100 may further include a lower casing 130 that covers the lower portion of the outer casing 110. The lower casing 130 is connected to at least one of the height adjuster, the main body and the swing motion unit 400.

The air purifier 500 purifies and supplies the outside air to the accommodation space 104 of the baby carriage body 100.

The air purifier 500 is formed to penetrate the baby carriage body 100 and has an inlet 503 communicating the outside with the accommodation space 104 and having external air sucked therein and a discharge port 502 discharging air therein A filter unit which is located inside the air passage 501 and which purifies the air sucked into the suction port 503 and a filter unit which is located inside the air passage 501 and which is connected to the discharge port 502 And an air blowing unit 510 that provides a flow force to cause air to flow.

The air passage 501 is formed through the baby carriage body 100 and communicates with the accommodation space 104 from the outside. The air passage 501 is disposed in the air purifying space. The air passage 501 is a space through which air flows.

The air flow path 501 is one flow path in which a suction port 503 is disposed at one side and a discharge port 502 is disposed at the other side.

The suction port 503 sucks outside air and is connected to the air flow path 501. The suction port 503 is formed through the outer casing 110.

Therefore, the air in the air passage 501 can be discharged in the tangential direction of an arbitrary circular arc centered on the center point C1 of the accommodation space 104 at the reference plane D1.

The reference plane D1 is an arbitrary plane intersecting a virtual line connecting the center point C1 of the accommodation space 104 and the center C2 of the entrance 102. [

Therefore, when the air in the accommodation space 104 forms the centrifugal circulation flow R, the external air and the internal air are not easily mixed, so that the quality and temperature of the air in the accommodation space 104 are maintained for a long time .

The air flow path 501 may further include a heater 600 for heating air passing through the air flow path 501. The heater 600 heats the air passing through the air passage 501. The temperature of the air supplied to the inside of the accommodation space 104 through the heater 600 can be adjusted.

5 is a partial cross-sectional view of the baby carriage body 100 for explaining the air curtain airflow.

As another example, a part of the discharge port 502 may form the centrifugal circulation flow R described above, and another part of the discharge port 502 may form the air curtain airflow A.

The air curtain airflow A restricts the air in the accommodation space 104 and the air outside the entrance 102 from being exchanged. The air curtain airflow A may mean an air current traveling in a direction parallel to a plane intersecting the center axis Ax connecting the center of the accommodating space 104 and the center C2 of the entrance 102. That is, the air curtain airflow A forms a wall between the accommodation space 104 and the outside air.

The discharge port 502 discharges the air to form an air curtain airflow that restricts the exchange of air in the receiving space 104 and air outside the outlet port 102.

Specifically, the discharge port 502 discharges the airflow traveling in a direction parallel to the plane D2 intersecting the central axis Ax connecting the center of the receiving space 104 and the center C2 of the entrance 102 And a third discharge port 502c.

The third discharge port 502c may be arranged in a direction parallel to a plane D2 intersecting the center axis connecting the center of the accommodating space 104 and the center C2 of the entrance 102. [ A plurality of third discharge ports 502c may be disposed.
