Description

Pillow cover unit, bed cover unit and bedding system with adjustable temperature and humidity

The present invention relates to bedding, in particular to a pillowcase unit, a bed cover unit and a bedding system that can adjust temperature and humidity.

The general public knows that the comfort of bedding such as headrests and mattresses will affect people's sleep quality. However, the sleep quality of ordinary people is not only affected by the comfort of bedding, but also directly or indirectly affected by the temperature and humidity in the environment. Correspondingly, the quality and quantity of sleep of ordinary people are also related to their quality of life and physical health. In addition, during sleep, the temperature, humidity and allergens in the surrounding environment will affect the clinical manifestations of ordinary people's physical health. In order to maintain appropriate temperature and humidity, it is usually necessary to set the temperature of the air conditioning system or the humidity setting of the dehumidifier before going to bed to maintain the sleeping environment at the optimal temperature and humidity to improve sleep quality. In addition, the use of air purifiers can effectively reduce the concentration of suspended particles and dust mites in the air, thereby improving sleep quality.

However, even with the intervention of the above-mentioned related devices, many people's sleep is still affected by improper temperature and humidity settings, or excessive allergens and other factors, resulting in dry mouth and worsening autonomic nervous system problems during sleep due to improper temperature or humidity settings. , or sleep disruption due to temperature discomfort. In addition to the aforementioned problems caused by allergens, pathogens, or suspended particles on bedding that cause respiratory tract inflammation, another main reason is that the temperature and humidity settings before going to bed are not necessarily suitable for use during sleep. In addition, if there are more than two people in the same space, it is easier for each person to have different requirements for temperature and humidity, resulting in different sleep effects. Temperature and humidity settings currently mainly come from the host's induction, so distortion of temperature and humidity can cause sleep problems at night. Furthermore, if allergies are the key to sleep disturbances such as nasal congestion during sleep, existing air purifiers cannot solve the problem of suspended particles and allergies around the face. The aforementioned suspended particles cause the mattress and the headrest located in the pillow case to become A key factor in the persistence of allergens.

Regarding the implementation of the respective breathable areas 211, 311 and the respective low breathable areas 212, 312 of the pillowcase body 21 and the bed cover body 31, it is possible to join the fabric of breathable material and the fabric of low breathable material to each other through tailoring. It is also possible to sew two low breathable material fabrics with the outlines of the low breathable areas 212 and 312 onto a corresponding breathable material cloth, thereby defining the outlines of the corresponding breathable areas 211 and 311. . Another embodiment is to spray or attach a chemical or bacteriostatic spray that is airtight to the pillowcase or bedcover on the inner or back surface of the existing pillowcase or bedcover, thereby forming a coating that is airtight to the pillowcase or bedcover. layer (that is, using a single fabric with subsequent processing) to achieve the purpose of air flow transmission with different air permeability designed in the present invention.

It should be noted here that the contours of the breathable area 211 and the low air permeability area 212 of the pillowcase body 21 are complementary to each other so that the breathable area 211 can become a running trajectory of the constant temperature and constant humidity airflow 411, and the The same is true for the contours of the air-permeable area 311 and the low-air-permeability area 312 of the bed cover body 31 being complementary to each other. Therefore, when the constant temperature and constant humidity airflow 411 enters the respective ventilation areas 211 and 311 from the air inlet 2111 of the pillowcase body 21 and the air inlet 3111 of the bed cover body 31, it can continuously blow the pillowcase body respectively. 21 and the pillows and mattresses in the bed cover body 31 provide the constant temperature and constant humidity airflow 411, so that the user can continue to be in the environment of the constant temperature and constant humidity airflow 411 while sleeping, with the airflow maintained.

It should be further explained that in order to make the breathable area 211 of the pillowcase body 21 and the breathable area 311 of the bed cover body 31 become the effective running trajectory of the constant temperature and constant humidity airflow 411, so as to generate annular airflow. Therefore, preferably, the breathable area 211 of the pillowcase body 21 surrounds the low breathable area 212 (as shown in Figures 1 and 2); the breathable area 311 of the bed cover body 31 surrounds the low breathable area 312 (such as 1 and 3), and the breathable area 311 and the low breathable area 312 of the bed cover body 31 are facing the user. In this way, the constant-temperature and constant-humidity airflow 411 continuously introduced into the breathable area 211 of the pillowcase body 21 and the breathable area 311 of the bed cover body 31 can be made to leave along the annular airflow in the direction away from the user (as shown in Figure 1 shown). In addition, in order to avoid the user's allergies and nasal congestion caused by dust mites. More preferably, the breathable area 211 and the low breathable area 212 of the pillowcase body 21 face the user's head (as shown in Figures 1 and 2).

Referring also to Figure 1, it can be seen from the foregoing description that the design of the breathable area 211 of the pillowcase body 21 and the breathable area 311 of the bed cover body 31 (as the effective running trajectory of the constant temperature and constant humidity airflow 411) in this embodiment of the present invention can During the user's sleep period, the constant-temperature and constant-humidity airflow 411 produced by the air-conditioning system 4 continues to generate annular airflow of appropriate temperature and humidity around the user, even if dust mites are originally attached to pillows and mattresses. Or suspended particles can also be taken away from pillows and mattresses with the annular airflow in the direction away from the user, thereby reducing the concentration of dust mites and suspended particles and preventing the user from being exposed to dust mites or suspended particles during sleep. and other disturbing factors that interrupt sleep. Furthermore, in the design of the breathable area 311 and the low breathable area 312 of the bed cover body 31, when the user lies on the bed cover body 31 during sleep, the compression of the user's body will cause The breathable area 311 in the compressed area causes wind resistance to the constant temperature and constant humidity airflow 411. At this time, the constant temperature and constant humidity airflow 411 will naturally run from the uncompressed area and leave the bed cover body 31, which can further assist in heating or heating. Cool the temperature of the compressed area.

More preferably, as shown in FIG. 4 , the pillow case unit 2 and the bed cover unit 3 each further include a swing leaf 23, 33. The swing leaf 23 of the pillowcase unit 2 is sewn to the pillowcase body 21 and surrounds an outermost periphery of the breathable area 211 of the pillowcase body 21. The swing leaf 33 of the bed cover unit 3 is sewn to the bed cover body 31 and surrounds it. An outermost periphery of the breathable area 311 of the bed cover body 31 . Through the design of the swing leaves 23 and 33, this embodiment of the present invention can better pass through the swing leaves 23 and 311 when the constant temperature and constant humidity airflow 411 runs in each ventilation area 211 and 311 while the user is sleeping. 33 allows the constant temperature and constant humidity airflow 411 to be effectively distributed at the swing leaves 23 and 33 to thereby enhance the retention effect of temperature and humidity.

It is worth mentioning that in order to reduce the degree of dust mite attachment to the pillow covered in the pillowcase body 21, the breathable area 211 and the low breathable area 212 of the pillowcase body 21 in this embodiment of the present invention can also be as shown in Figure 5 Generally, the low air permeability area 212 of the pillowcase body 21 surrounds the air permeability area 211 thereof. Specifically, when the user is not sleeping, the pillow can be placed in the pillowcase unit 2 as shown in Figure 5, and the user can also set a high temperature (for example, 50°C) through the setting module 45 of the air conditioning system 4. ) sterilization command to transmit the high-temperature sterilization command to the processor 43 through the communication module 44. After receiving the high-temperature sterilization command, the processor 43 creates a high-temperature sterilization air flow from the host 41 (not shown in the figure) ), to transport the high-temperature sterilization airflow to the first output port 421 of the pipeline 42 via the pipeline 42, so that the high-temperature sterilization airflow is introduced into the pillowcase body shown in Figure 5 through the air inlet 2111 of the pillowcase body 21 21 circulates in the breathable area 211. At this time, since the low air permeability area 212 of the pillowcase body 21 surrounds the air permeability area 211, once the high temperature sterilization airflow is introduced into the pillowcase body 21, the high temperature sterilization airflow will be concentrated from the surrounding low air permeability area 212 and directed toward the pillowcase body 21. The breathable area 211 circulates. Therefore, dust mites or suspended particles originally attached to the pillow can be eliminated and taken away with the high-temperature sterilizing airflow, which is beneficial to reducing the concentration of dust mites and suspended particles in the space. In order to effectively achieve the purpose of sterilization, this embodiment can also design an airtight packaging bag in addition to the pillowcase body 21 and the bed cover body 31, so that the airtight packaging bag can be exposed first through the high-temperature sterilization instruction. In the environment of the high-temperature sterilizing air flow, the pillowcase body 21 and the bed cover body 31 are then placed in the airtight packaging bag containing the high-temperature sterilizing air flow to achieve more effective sterilization and disinfection purposes.

From the detailed description of the above paragraphs of the present invention, it can be seen that the present invention mainly obtains and integrates the user's own body temperature and the temperature and humidity of other adjacent areas through the temperature and humidity sensor 22 of the pillowcase unit 2 and the temperature and humidity sensor 32 of the bed cover unit 3. The temperature around the body (equivalent to the aforementioned actual temperature), and at the same time, dynamic air flow control is used to help improve the function of balancing temperature and humidity, and the actual temperature is used to save the time spent by the air conditioning system 4 in producing the constant temperature and constant humidity air flow 411.

(3) Through the cooperation of the temperature and humidity sensors 22 and 32 and the smart control chip 46, the temperature and humidity can be simply dynamically adjusted for the space near the user's body. Not only can the set target temperature be reached faster, but also There is no need to adjust the temperature and humidity of the entire space (such as the entire bedroom) and cause energy waste, which is in line with environmental protection requirements. In addition, the temperature change can also be adjusted to the appropriate temperature in response to changes in the autonomic nervous system and biological clock during different sleep cycles to prevent the user from catching a cold.

(4) Through this high-temperature sterilization instruction and the design of the low-breathable area 212 of the pillowcase body 21 surrounding the breathable area 211 shown in Figure 5 (i.e., a closed system), the risk of being in a closed system for a long time can be effectively reduced. The concentration of dust mites and suspended particles near the face in pillows can improve problems such as atopic dermatitis and nasal allergies.

(5) If it is used by two people, the layout of two temperature and humidity adjustable bedding systems of this embodiment can be used to enable the two people to set their own temperature and humidity commands according to their respective needs for temperature and humidity.
