Description

  The present invention relates to a blower for a mattress with a cradle, and more specifically, a cradle that enables switching of the direction of the upper and lower parts of a blower body and efficiently changing the height of a blower port depending on the situation. The present invention relates to a blower for a mattress with a cradle.

  In general, a mattress is a product in which an elastic member is incorporated, or a product made of a material having excellent elasticity so that the person can take a rest or sleep in an easy posture.

  That is, the mattress is formed by stacking a plurality of fibers made of a material having high elasticity, or providing relatively high strength fibers on the upper surface and the lower surface, and interposing an elastic member such as a metal spring between them. Therefore, when elasticity is generated in the vertical direction and the user lies down, a cushioning action is performed so that a comfortable sleep can be obtained.

  However, when a user sleeps, a normal mattress is maintained according to the surrounding temperature regardless of the surrounding temperature. Therefore, if the ambient temperature increases, the mattress temperature also increases, and if the ambient temperature decreases, the mattress temperature also decreases, which may be too hot or too cold in midsummer or midwinter. It is difficult to get a comfortable sleep.

  In order to make up for the disadvantages of such conventional mattresses, electric mattresses that can heat the mattresses by placing heating wires in a predetermined shape inside and connecting the power supply to supply electricity, or plates that can be filled with water Water mattresses and the like have been developed in which water is supplied to the inside through a tube-like tube so that the temperature of the mattress can be kept low.

  However, the electric mattress has a demerit that it consumes a lot of electric power because it generates a large amount of electromagnetic waves and is unhealthy and uses electric resistance. In addition, when the electric mattress overlaps, there is a concern that the heating wires arranged inside may be short-circuited, and in this case, there is a serious demerit such that a fire may occur.

  Furthermore, water mattresses also often use hot wires to fill the interior of the plate-like tube and cool or heat the temperature, which in this case has the same problems as the electric mattress described above. Not only that, water mattresses have water inside, so if the tube is torn or ruptured, there is a problem of high electric shock.

  Recently, as another method for solving the above-described problem, a blower that injects air into the mattress has been developed.

  However, the blower port applied to the mattress blower according to the prior art has a problem that the position of the blower port cannot be changed corresponding to the height position where the mattress is provided.

  In addition, the mattress blower according to the prior art has a structure in which the main body itself is directly fixed to the mattress, so that vibrations generated during the operation of the blower are directly transmitted to the mattress. There was a structural problem that I could not sleep well.

The vertical position of the air blowing unit is switched according to the position to be operated.

  The upper and lower portions of the case main body are formed with oblique bending rate portions where the thickness of the side surface gradually decreases from one side to the other side.

  The cradle is connected to the first oblique receiving portion that forms a coupling surface that is in close contact with the oblique bending rate portion, and the second oblique connecting portion is connected to the first oblique receiving portion and extends in a facing direction. And an oblique receiving portion.

  The first oblique receiving portion may be formed with at least one coupling protrusion that is coupled to the detachable coupling groove.

  Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to FIGS.

  As shown in the figure, the air blower for mattress with cradle according to the present invention includes a case main body 100 having heat exchange means for generating cold air or hot air necessary for air conditioning, and the case main body 100 is provided with a cool air Or the ventilation unit 200 which ventilates warm air outside, the control switch 300 provided in the said case main body 100, and the cradle 400 which fixes the said case main body 100 stably to the ground are provided.

  First, the case main body 100 is a box-shaped structure having a predetermined volume and size, and heat exchange means (not shown) for generating cold air or hot air necessary for air conditioning is provided therein.

  The heat exchanging means is a component that realizes cooling and heating. By sending cool air in summer and lowering the temperature inside the mattress M, a comfortable sleep is realized, and warm air is given in winter. It is a temperature control device that delivers warm sleep by sending it out.

  The heat exchanging means may be manufactured in a heat pump type or may be manufactured in a configuration using a thermoelectric element. Since such a configuration is a well-known technique in the industry, its specific configuration and A description of the operation is omitted.

  Further, a suction port 101 for sucking outside air is formed on one side of the case body 100, and a blower port unit 200 for blowing cool air or warm air to the outside is provided on the other side.

  One side of the case main body 100 in which the suction port 101 is formed is manufactured by a case lid body 110 having a detachable connection structure.

  That is, the inside and the inside of the case main body 100 can be cleaned and maintained by the structure that opens and closes the case lid 110.

  A filter member 102 is provided on the back surface of the case lid 110 to filter out foreign substances contained in the air flowing through the suction port 101 (see FIG. 3).

  Furthermore, a detachable coupling groove 120 is formed on the upper and lower portions of the case main body 100 with the case lid 110 removed so as to be able to perform complementary detachable coupling corresponding to a cradle 400 described later. .

  That is, the detachable coupling groove 120 is not provided in a structure in which the case body 100 is simply placed on the cradle 400, but by providing a groove having a structure that is physically coupled to the constituent elements of the cradle 400. The coupling strength between the case body 100 and the cradle 400 can be greatly improved.

  In addition, the upper and lower portions of the case body 100 according to the present invention are formed with an oblique bending rate portion 103 in which the thickness of the side surface gradually decreases from one side to the other side.

  That is, as shown in FIG. 4A and FIG. 4B, the cradle 400 is formed on the upper or lower portion of the case body 100 by manufacturing the upper and lower side surfaces of the case body 100 in the same standard shape. This is so that the respective connections are performed.

  This is for changing the height position of the air outlet unit 200 described later upward or downward according to the height position of the mattress M.

  In other words, when the mattress M is placed on the mattress frame, the cradle 400 is coupled to the lower part of the case body 100 so that the air blowing unit 200 is located at a high place, and conversely, the mattress M is close to the ground. If it is located, the case body 100 is rotated 180 degrees in a state where the receiving base 400 is coupled to the upper part of the case body 100 so that the air outlet unit 200 is located on the lower side. The height position may be variable.

  As described above, the case body 100 is technically characterized in that the vertical position of the air outlet unit 200 can be switched according to the position where the cradle 400 is coupled. .

  Needless to say, the detachable coupling grooves 120 formed in the upper and lower portions of the case body 100 naturally have a clean appearance that is not exposed to the outside due to the configuration of the case lid 110 and the cradle 400. Hold.

  In addition, a gripping groove 130 is formed in the case body 100 so that it can be easily carried to other places.

  Moreover, you may provide the illuminating lamp (not shown) which alert | reports the operation state of a heat exchange means in the one part area | region of the peripheral direction of the said case main body 100. FIG.

  That is, when the heat exchanging means performs a cooling operation, the illuminating lamp emits blue light, and when the heat exchanging means performs a heating operation, the red light is emitted. Makes it easy for the user to grasp the current operating state.

  The air blowing unit 200 is provided at the upper part on the other side of the case body 100 and plays a role of blowing cool air or warm air generated in the heat exchange means into the mattress M.

  The air blowing unit 200 according to the present invention projects outward from the surface of the case body 100.

  The air outlet unit 200 having such a protruding structure is very effective in providing a coupling structure for supplying cold air or hot air to the inside of the mattress M.

  Specifically, the air outlet unit 200 includes a fixed guide member 210 that is fixed to the case body 100, a movable guide member 220 that is detachably coupled to an end side of the fixed guide member 210, and the fixed An air duct 230 is connected to the guide member 210 at one end and the other end is connected to the movable guide member 220.

Here, the air duct 230 is made of a bellows tube that can be expanded and contracted.
As described above, the air duct 230 manufactured in the bellows tube structure can be provided not only at a position where the case body 100 is separated from the mattress M by a predetermined distance, but also between the mattress M and the air outlet unit 200. It is possible to effectively cope with the height difference.

  In addition, the air duct 230 is preferably manufactured by a plurality of components divided independently.

  That is, the independent air duct 230 can transmit a stable strength of wind power to the entire inside of the mattress M.

  In other words, the reason why the air duct 230 is made of a plurality of small-diameter tubes is that the principle defined in Bernoulli, that is, moving the small-diameter passage more than the speed at which the gas moves through the large-diameter passage. Based on the principle that the flow velocity of the gas is higher, the effect that the blowing pressure can be further improved so that the blowing pressure is uniformly transmitted to the entire inside of the mattress M. It is because it plays.

  In addition, bearings 240 are provided at both ends in the longitudinal direction of the air duct 230 so as to be rotated in accordance with the air pressure.

  That is, by adding a component that allows the air duct 230 to rotate naturally in response to the pressure of the air flowing through the air duct 230, the durability of the air duct 230 is further improved. This can be further improved.

  Here, a thrust bearing is preferably used as the bearing 240.

  The fixed guide member 210 and the movable guide member 220 are formed with a bearing receiving groove 201 that rotatably supports the bearing 240.

  At this time, it goes without saying that the bearing receiving groove 201 is also formed in each independent structure corresponding to the independent structure of the air duct 230.

  In addition, the fixed guide member 210 and the movable guide member 220 are manufactured by split assemblies 210a, 210b, 220a, and 220b that are coupled in the vertical direction with the air duct 230 interposed therebetween.

  Further, the fixed guide member 210 and the movable guide member 220 are formed with a one-touch fastening portion 250 that is detachably coupled to each other.

  That is, when the air blower for mattress is not used, the air outlet unit 200 does not protrude, so that not only the volume can be minimized, but also the air duct 230 can be prevented from being exposed to the outside. There exists an effect that it can protect safely so that a deformation | transformation does not arise.

  Furthermore, a filter net 221 is provided inside the movable guide member 220 to prevent foreign substances of a predetermined size from entering.

  On the other hand, the control switch 300 is provided in the case body 100 or the case lid body 110, and selectively controls the heat exchange means, and performs a functional operation on the power source and wind power of the case body 100. Play a role to control.

  Here, it is preferable that the control switch 300 is provided on the case lid 110, even if detachable coupling is performed such that the position of the case lid 110 is 180 ° variable with respect to the case body 100. A component of a pogo pin is provided to automatically connect the power source and the signal line in accordance with the combined position without turning off the power source and the signal line.

  The constituent elements of the control switch 300 are also the same as or substantially the same as a publicly-known technique widely used in the industry, and a description of a specific configuration and operation thereof will be omitted.

  Meanwhile, the cradle 400 is a component that is detachably coupled to the case main body 100, and stably fixes the case main body 100 to the ground. Alternatively, it plays a role of switching the vertical position of the air blowing unit 200 according to the position where it is coupled to the lower detachable coupling groove 120.

  The cradle 400 according to the present invention is connected to a first oblique receiving portion 410 having a coupling surface 411 that contacts the oblique bending rate portion 103 in a state of being coincident with the first oblique receiving portion 410, and is opposed to the first oblique receiving portion 410. And a second oblique receiving portion 420 extending in the direction of the movement.

  That is, when the cradle 400 is viewed from the side, the connection structure between the first oblique receiving portion 410 and the second oblique receiving portion 420 has a substantially “∧” shape.

  In particular, the first oblique receiving portion 410 is formed with at least one coupling protrusion 412 that is coupled to the detachable coupling groove 120.

  That is, since the coupling protrusion 412 enters the detachable coupling groove 120 of the case body 100 and the both are coupled, the binding force between the case body 100 and the cradle is increased during the coupling. It can be maximized.

  Here, the coupling protrusion 412 is preferably manufactured by two components formed on one side and the other side in the longitudinal direction of the first oblique receiving portion 410.

  Further, an elastic fastening piece 413 having a locking projection 413a is formed on one side of the coupling protrusion 412. The detachable coupling groove 120 has a locking groove (not shown) for receiving the locking projection 413a. Is formed.

  This serves to prevent the coupling protrusion 412 coupled to the detachable coupling groove 120 from being disengaged by an arbitrary external pressure.

  In other words, the binding force between the detachable coupling groove 120 and the coupling protrusion 412 can be released only after transmitting a predetermined pressure for pulling the cradle 400 in the linear direction.

  Further, it is preferable that the coupling protrusion 412 is manufactured so that the cross-sectional thickness decreases from the lower part to the upper part.

  This is so that the detachable coupling between the detachable coupling groove 120 and the coupling protrusion 412 can be performed more smoothly.

  Furthermore, a plurality of auxiliary coupling ribs 414 smaller than the coupling protrusion 412 are formed on the first oblique receiving portion 410.

  Needless to say, auxiliary coupling grooves 121 for accommodating the auxiliary coupling ribs 414 are naturally formed in the upper and lower portions of the case body 100 (see FIG. 3).

In addition, the second oblique receiving portion 420 has a rectangular bottom surface that contacts the ground.
This is to increase the area in contact with the ground and greatly increase the frictional force associated therewith.

  In addition, a sealing pad (not shown) may be provided around the peripheral direction of the coupling surface 411 so that a tight sealing connection with the upper or lower outer wall surface of the case body 100 is performed. .

  Due to the components of the cradle 400, the case body 100 can maintain a stable upright posture.

  The above-described present invention is not limited in any way by the above-described embodiment and the accompanying drawings, and various substitutions, modifications, and changes can be made without departing from the technical idea of the present invention. This is obvious to those having ordinary knowledge in the technical field to which the present invention belongs.
