Description

  The present invention relates to a bed apparatus that can constitute a comfortable warm (cold) thermal environment above the floor of the bed.

  Conventionally, various bed apparatuses for providing a comfortable warm (cold) thermal environment for a user who is lying on the bed floor have been proposed.

  For example, Patent Document 1 relates to a bed having a configuration in which cold air or hot air generated by an air conditioner is blown out from an opening formed in the vicinity of the bedside of the head unit. Although the apparatus is provided, the movement becomes free, and the installation work of the air conditioner can be eliminated when installing the bed. Moreover, in this bed, the air conditioner is constituted by a thermoelectric conversion element, and by this, the exhaust heat generated when cold air is generated is stored in the heat storage material without being exhausted into the room, thereby warming the room by exhaust heat, This is to prevent the bed user from feeling uncomfortable.

  Patent Document 2 proposes a bed provided with an air conditioner having an outdoor unit as a component, unlike Patent Document 1, and this bed stores a heat exchanger and a blower in its head. The air sucked from the suction grill of the head storage box by this blower is cooled or heated by a heat exchanger, and the cooled or heated air is directly supplied from the blow grill of the head storage box. In particular, the air is blown near the head of the bed user.

Further, Patent Document 3 is such that a pillar-use panel is erected on the upper left and right sides of the bed, a ceiling panel is placed and fixed on the upper part, and a cover is formed on the front and rear sides with a vinyl curtain. A bed apparatus is proposed in which an isolated space is configured and clean air from an air conditioner with an air cleaning function is supplied to the space.

  Since both of Patent Documents 1 and 2 are configured to blow cold air or hot air directly to the bed user on the bedside side, the bed user is given an uncomfortable feeling due to the direct air flow and is applied to the bedside. An unpleasant feeling will be given by the operation sound of the air blower, the compressor, etc. which are the components of the installed air conditioner.

  Further, in Patent Documents 1 and 2, since the upper space of the bed is open, air conditioning with blowing air-conditioned air has a large heat loss, and in order to obtain a sufficient air-conditioning effect, the entire room can be air-conditioned. It is necessary to supply conditioned air, energy consumption is large, and energy efficiency is low.

On the other hand, in the case where the space separated from the outside is air-conditioned in the upper part of the bed as in Patent Document 3, a sufficient air-conditioning effect can be obtained with less energy consumption. Therefore, the bed user is isolated and uncomfortable.

FIG. 1 is a perspective view showing a main configuration, FIG. 2 is a perspective view of a use state, and FIG. 3 is a line AA in FIG. 4 is a partial cross-sectional view taken along line BB in FIG. 3, and FIG. 5 is an example of an operation / display panel unit.
In the figure, reference numeral 1 denotes a bed and 2 denotes a floor portion. In this embodiment, the floor 1 has a configuration in which a mattress 5 or the like is fitted and placed in a recess 4 formed in the bed frame 3.

  Reference numeral 6 is a headboard, and 7 is a footboard. The headboard 6 has a first air outlet group 8a disposed laterally on the upper inner surface side, and second and second disposed vertically on the inner surface side of the side portion. Three outlet groups 8b and 8c are provided. The head board 6 and the foot board 7 are provided with a surface heat source 9 indicated by a broken line in the drawing on the inner surface side thereof. As described above, the surface heat source 9 may be provided only on either one of the headboard 6 and the footboard 7 as in this embodiment.

  Next, an example of the surface heat source 9 will be described. First, as a surface heat source dedicated to heating, a thermal panel configured in a panel shape provided with a ceramic heater or a heating wire can be used, and both the heating and cooling can be used. As a surface heat source, a panel that forms a panel shape by installing a pipe for flowing water (hot water or cold water) or other refrigerant as a working fluid, or a thermoelectric element such as a Peltier element is configured in a panel shape Heated / cooled panels can be used.

  On the other hand, on the side edge side of the floor portion 2, in this case, on the side edge side of the bed frame 3, the fourth and fifth air outlet groups 8d and 8e are arranged laterally along the length direction. Air is blown upward from the air outlet groups 8d and 8e.

  As shown in the figure, the second and third outlet groups 8b and 8c and the fourth and fifth outlet groups 8d and 8e are arranged such that the outlet directions do not intersect with each other. 8d and 8e are shifted so as to be arranged outside the floor portion 2 rather than the second and third outlet groups 8b and 8c. Of course, it is possible to shift in the opposite direction.

  As shown in FIGS. 3 and 4, the air outlet groups 8 a to 8 e have a configuration in which the air outlets 8 are provided along the length direction of the duct 10 arranged in the above-described direction. It is set as the structure connected to the air supply source 11 comprised in the right place. Although FIG. 4 shows a configuration in which only one air supply source 11 is installed on the bed frame 3, the number of installed air supply sources and the installation location can be set as appropriate. For example, an air supply source can be provided in the headboard 6 (or footboard 7) itself for the outlet groups 8a to 8c of the headboard 6 (or footboard 7), or the same outlet group 8a to 8e. An air supply source can be provided for each of the plurality of air outlets 8 at an appropriate number, for example, every five air outlets 8. Further, the air supply source 11 can be provided outside the bed 1.

  Reference numeral 12 denotes an operation / display panel, and FIG. 5 is an explanatory diagram showing an example of the operation / display panel unit. Reference numeral 13 is a main power switch, 14 is an operation switch used for temperature increase / decrease operation, menu selection operation, etc., 15 is a mode switch for selecting and displaying a menu such as heating and cooling, and 16 is an operation / setting state. It is a display unit.

  The configuration of the bed 1 is appropriate in addition to those described above. For example, a configuration in which the legs 17 are provided as shown in FIGS. 1, 3, and 4, or a configuration in which the legs are not provided as shown in other drawings. It can also be.

  In the above configuration, the first air outlet group 8a, the second air outlet group 8b, the third air outlet group 8c, the fourth air outlet group 8d, and the fifth air outlet are operated by operating the air supply source 11. When air is blown out from the group 8e, the floor is blown by air blown horizontally in the direction of the footboard 7 from the respective outlets 8 of the first outlet group 8a arranged in the lateral direction on the upper inner surface side of the headboard 6. An air curtain is formed above the portion 2. Further, the floor portion 2 is caused by air blown horizontally in the direction of the footboard 7 from the air outlet 8 of the second and third air outlet groups 8b and 8c arranged in the vertical direction on the inner side of the side portion of the headboard 6. Air curtains are formed on the sides on both sides. Further, from the respective outlets 8 of the fourth and fifth outlet groups 8d and 8e arranged laterally on the side edge side of the floor portion 2 of the bed 1, the second and third outlet groups 8b and 8c are connected. Air curtains are also formed on both sides of the floor 2 by the air blown upward at a position shifted outward from the air blown from the blower outlet 8.

  In this way, a space with low heat loss can be formed above the bed floor by being isolated from the outside in a thermal and / or cold manner (hereinafter referred to as “hot (cold) thermal”). Accordingly, by supplying warm (cold) heat to the space formed by the air curtain by an appropriate warm (cold) heat supply means, a comfortable warm (cold) can be provided above the floor 2 of the bed 1 with less energy. ) Thermal environment can be configured.

  In this embodiment, as the means for supplying warm (cold) heat into the space formed by the air curtain, the surface heat source 9 provided on the inner surface side of the headboard and the footboard as described above is used. Warm (cold) heat can be supplied to the person by the radiant heat and natural convection in the vicinity.

  Therefore, there is no need for a rotating device such as a blower for supplying warm air or cold air to the bedside as in the prior art, and therefore no noise is generated, thereby ensuring quietness essential for comfortable sleep. As well as being able to feel uncomfortable because hot air or cold air by forced convection does not directly hit the body.

  For example, in the heating period, intrusion of cold air can be prevented by the air curtain, so that a sufficient heating effect can be expected even when the surface temperature of the surface heat source is a relatively low temperature of about 30 degrees, and the headboard 6 It is also possible to control the temperature of the surface heat source 9 on the side and the footboard 7 side differently, and it is possible to meet the demands of a wider variety of bed users. For example, when the bed user has a cooling property, the control considering the cause of the cooling property can be performed, and the control for reducing the temperature difference between the upper body and the lower body can be performed.

  On the other hand, since air can be prevented from entering by the air curtain during the cooling period, the surface temperature of the surface heat source can be set to a temperature slightly lower than the body temperature to gently give the bed user cold heat. Can do.

  The air blowing direction of the first air outlet group 8a of the headboard 6 is configured to be variable in the vertical direction, and the air blowing direction is directed obliquely downward, so that the bed user extends from the upper body side to the lower body side. It can also be operated in the wind.

  As the surface heat source 9, as described above, a thermal panel or the like configured in a panel shape with a ceramic heater or heating wire can be used, and both the hot and cold surface heat sources 9 can be used as a working fluid. Use a hot / cold panel that is constructed in the form of a panel by installing pipes through which water (warm water or cold water) and other refrigerant flows, and a thermal panel that is constructed in the form of a panel by installing thermoelectric elements such as Peltier elements However, natural energy as well as commercial electricity can be used as the energy.

  For example, in the case where a hot / cold heat panel configured as a panel by installing a pipe for flowing water (hot water or cold water) as a working fluid or other refrigerant as the surface heat source 9 is used, It is possible to circulate the working fluid that flows to the heat storage tank. In this configuration, a heat storage operation process and a heat storage use operation process are set, and in the heat storage operation process, a boiler, a fuel cell, a heat pump, a solar water heater, or the like is used to supply warm (cold) heat to the heat storage body in the heat storage tank. In the process of storing heat and then using the heat storage, the heat (cold) heat in the heat storage tank can be supplied to the heat / cool panel by using a heat medium, and can be radiated and used. In this case, natural energy such as radiant cooling at night can be used as the cooling heat necessary for the cooling period, and hybrid operation can be performed by combining this with commercial power.

  The above-described heat storage tank can be configured as a dedicated device for the bed apparatus of the present invention, but can also be configured as a part of a system integrated with a heating / cooling hot water supply system in a home or a hospital.

  The surface heat source 9 detects the surface temperature by several temperature sensors arranged at several points, performs temperature control with the average value, and sets the upper limit of the temperature at each point, and controls the upper limit. Therefore, it is possible to prevent burns and fires.

  In this embodiment, as described above, the mattress 5 and the like are configured to be fitted and placed in the recess 4 formed in the bed frame 3, so that a sufficient distance from the heat radiation surface of the surface heat source 9 can be secured. Yes, and in this way, the effect of preventing burns and fires can be enhanced.

Next, the mode of blowing air from the respective outlets 8 of the outlet groups 8a to 8e will be described.
Basically, ON / OFF of air blowing from the respective outlets 8 of the outlet groups 8a to 8e for forming the air curtain is performed by the main power switch 13 of the operation / display panel 12 as described above. However, in addition to this, for example, to prevent the air blown out when entering or leaving the bed from hitting the bed user, it is possible to judge the posture of the bed user on the floor 2 and turn it on / off. It is.

  That is, when the bed user gets up from the bed and reaches the end sitting position or the like, it can be detected by a posture detection sensor such as a so-called bed leaving sensor and controlled to be turned off.

  In the present invention, air blowing from the respective outlets 8 of the outlet groups 8a to 8e is maintained throughout the bed user's sleep, thereby maintaining a warm (cold) thermal environment. Since it is basic, each of the outlets 8a to 8e of the outlet groups 8a to 8e, particularly the fourth and fifth outlet groups 8d and 8e, inhibits the blowing of air when the bed user turns over. It is necessary to set the position in advance so as not to be performed. This makes it possible to effectively maintain the comfort of the bed user at bedtime.

  On the contrary, when the bed user's body reaches the side edge of the floor portion 2 using the air blown out from the respective blowout openings 8 of the fourth and fifth blowout groups 8d and 8e, It is also possible to control the bed user to prevent falling from the bed.

  Moreover, the alarm function can be given using the blowing of the air from each blower outlet 8 of the blower outlet groups 8a-8e. In this case, the wake-up effect can be increased by applying the air from the air outlet 8 to a part thought to be coming out of the bedclothes such as the bed user's face and limbs. The wind pressure of the air blown from 8 can be changed.

Next, another embodiment of the arrangement of the outlet groups for forming the air curtain in the present invention will be described.
