Description

TECHNICAL FIELD OF THE INVENTION

The present invention relates to a pebble bed sauna device, which features omnidirectional heating, excellent security measures, and improved heating/warming effect.

DESCRIPTION OF THE PRIOR ART

Pebble bed sauna generally has a heating source that includes a heating plate arranged in a bed, so that when a user lies on the bend, heating performed with the heating plate makes radium stones warm and hot and emit far infrared light to apply and achieve an effect of pebble sauna, which is also known as stone spa by the general consumers, to human bodies. However, such a manner of generating heating only through the bed may suffer insufficiency area of heating to a human body, which leads to insufficient apparent temperature; oppositely, if temperature rising is made excessively, it would be impossible for a human body to stay in contact with the high-temperature radium stones for an extended period of time. Further, burning events may occur during the operation of the pebble bed sauna. It is quite apparent that protection achieved with security measures may not be perfect.

The pebble sauna, during the use thereof, suffers at least the following disadvantages that require further improvement:

(1) Heating is only made through the bed so that heating to a human body is only applied to a limited local area, and this leads to an apparent temperature that is not sufficient and may affect a heating/warming resonant effect.

(2) With only one layer of radium stones on a heating plate, improper control temperature would readily cause burning.

(3) Security and protection mechanisms for persons or facility are lacking.

SUMMARY OF THE INVENTION

The primary objective of the present invention is to make heating to a human body through both a bed heating member and a chamber heating member, in order to provide an omnidirectional heating effect and to use a thermal isolation member to prevent the human body from contacting the chamber heating member and to add a smooth pebble layer on energy stones to prevent the human body from directly contacting high-temperature stones.

To achieve the above objective, the present invention provides a main structure that comprises: a bed; at least one bed heating member arranged on the bed; at least one bed heat-isolation member arranged between the bed and the bed heating member; a plurality of energy stone layers arranged on one side of the bed heating member that is distant from the bed heat-isolation member; a plurality of smooth pebble layers arranged on one side of the energy stone layer that is distant from the bed heating member; a covering chamber movably disposed on the bed; at least one chamber heating member arranged inside the covering chamber; at least one heat isolation element arranged on one side of the chamber heating member that is adjacent to the bed; at least one chamber heat-isolation member arranged on one side of the chamber heating member that is distant from the heat isolation element; at least one surface layer formed on an outside surface of the covering chamber; at least one bonding layer arranged between the chamber heat-isolation member and the surface layer; and a controller arranged on the bed and electrically connected to the bed heating member and the chamber heating member.

When a user uses the present invention to do pebble bed sauna or stone spa, since the bed heating member of the bed is mounted by the bed heat-isolation member to the bed and a smooth pebble layer is additionally laid on the energy stone layer that is in direct contact with the bed heating member, it is possible to prevent a human body from directly contacting the bed heating member or the energy stone layer that might be of a high temperature, and also, the smooth pebble layer may take the place or cover the energy stone layer that is irregular to provide a smooth and rounded surface for contacting the human body and thus ensuring comfortable perception of contact and touch. Further, the covering chamber is provided with the chamber heating member on an inside thereof and upper and lower sides of the chamber heating member are respectively provided with the chamber heat-isolation member and the heat isolation element so as to completely avoid the potential risk of burning caused by unexpected touch of a user.

With the above technology, the problems of the prior art pebble bed sauna that a heating area of a human body is limited to a local region, the apparent temperature is not sufficient, a warming/heating resonant effect is poor, and burning may easily occur can be overcome to achieve the above advantages.

As shown in FIGS. 1-7, the bed 1 is provided, in sequence from bottom to top, with the bed heat-isolation member 21, the bed heating member 22, the energy stone layers 23, and the smooth pebble layers 24, and the covering chamber 3 is formed of the surface layer 45, the bonding layer 44, the chamber heat-isolation member 43, the chamber heating member 42, and the heat isolation element 41 arranged in sequence from outside to inside and is controlled by the controller 5 that is arranged on the bed 1 and electrically connected to the bed heating member 22 and the chamber heating member 42 for a heating temperature thereof. An example of the bed heat-isolation member 21 and the chamber heat-isolation member 43 is needle-punched fabric; an example of the bonding layer 44 is glass fiber fabric; an example of the heat isolation element 41 is negative-ion mesh fabric; the energy stone layers 23 can be any combination of radium stones, volcanic rock, hokutolite, germanite, tenshoseki, chert; and the smooth pebble layers 24 can be any combination of cobblestone or Yuhua stone.

In practical uses, as shown in FIGS. 5 and 6, to allow a person to smoothly lie on the bed 1, the sliding parts 321 of the second chamber 32 are caused to slide on the position-limiting rails 11 of the bed 1 (wherein, in this embodiment, the position-limiting rail 11 and the sliding part 321 are configured as a recess-and-projection arrangement for mutual engagement for position limiting), so that the second chamber 32 is arranged on and covers and overlaps the first chamber 31, and the pivot pins 311 of the first chamber 31 are caused to rotate in the pivot-joint troughs 12 to make the first chamber 31 rotated, about a rotation center defined by the pivot pins 311, to lift upward and open, and at the same time driving the second chamber 32 that is arranged on the first chamber 31 to open. The user lies down on the bed 1, and the first chamber 31 and the second chamber 32 are moved in opposite directions to have the first chamber 31 covering a lower half of the human body and the second chamber 32 covering an upper half of the human body. For a better warming/heating space, a covering member 322 may be provided at an open end of the second chamber 32 to collaborate with the covering chamber 3 to enclose hot air in the interior.

Since the bed heating member 22 of the bed 1 is fixed by the bed heat-isolation member 21 to the bed 1 and since the bed 1 is generally formed of a wooden frame, it is possible to reduce damages that the bed heating member 22 causes on the bed 1, and further, a smooth pebble layer 24 can be additionally laid on the energy stone layer 23 that is in direct contact with the bed heating member 22, wherein the smooth pebble layer 24 is formed of flat, smooth and rounded stones having smooth surfaces in order to take the place of the energy stone layer 23 that is irregular to prevent acute surface or corrugation of the energy stone layer 23 from contacting and touching human body, thereby providing comfortable perception of contact. Further, the covering chamber 3 is also provided, on an inner side thereof, with the chamber heating member 42, and upper and lower sides of the chamber heating member 42 are respectively provided with the chamber heat-isolation member 43 and the heat isolation element 41 to prevent burning caused by accidental contacts of the human body with the inside surface of the covering chamber 3, while on the upper side, high temperature is prevented from transmitting to the surface layer 45 to cause burning in case of contact with or touch on the covering chamber 3. In this way, potential risk of burning due to accidental contact of a user is completely avoided. Further, in the instant embodiment, the surface layer 45 is embodied as an example of being made of golden polyurethane (PU) leather, and for the synthetic PU leather, processing or treatment can be taken according to different strengths, abrasion resistances, coldness resistance, colors, glossiness, and patterns to include features of diversified textures, bettered water resistance, and neat and clear configuration and being of light weight, wear resistant, and skidding resistant, to further improve overall outside appearance and quality of the present invention.
