Description
[ technical field ]
The invention relates to a refrigerator, in particular to a refrigerator with a gas sanitation module.
[ background art ]
In the related art, a gas sensor is disposed in a refrigerator to detect the air condition in the refrigerator, for example, whether one or more types of gases are included in a storage chamber, the content/concentration of one or more types of gases in the storage chamber, and other information, so that a user can know the air condition in the refrigerator through a display of the refrigerator or a remote terminal. The user can perform corresponding processes, such as cleaning the stored goods in the refrigerator or turning on the air cleaning device to clean the air in the refrigerator, according to the detection result of the gas sensor.
[ summary of the invention ]
It is an object of embodiments of the present invention to provide an improved refrigerator with a gas sanitation module.
An object of an embodiment of the present invention is to provide a refrigerator advantageous to improve efficiency of a gas sanitary module.
One embodiment of the invention relates to a refrigerator, which is characterized by comprising a storage chamber with a front opening; a door to close the storage chamber; and a gas sanitation module comprising a housing and a gas detection and/or purification unit located within the housing; the gas sanitation module is fixed to a top wall of the storage compartment, and the gas sanitation module includes an air inlet at the housing, the air inlet being inclined downward and rearward.
In this arrangement, while the air inlet is not readily exposed directly to the front opening of the storage compartment, it is also advantageous for air within the storage compartment to enter the gas sanitation module, for example for gas detection and/or gas purification, thereby facilitating ensuring the operating efficiency of the gas sanitation module.
The gas sanitation module may include at least one of a gas detection unit and a gas purification unit.
In one possible embodiment, the angle between the air inlet and the horizontal plane may be between 20 and 45 degrees. This is particularly advantageous for the air of the storage compartment to enter the gas sanitary module, which increases the efficiency of the gas sanitary module.
In one possible embodiment, the gas sanitation module is proximate to a front opening of the storage compartment. Thus, the air inlet may be directed towards the main storage area of the storage compartment, facilitating detection and/or purification of air in the vicinity of the main storage area into the gas sanitation module. In addition, when the gas sanitation module has a gas detection unit, air in the user sensitive area is more easily detected at the front opening of the storage compartment. For the semiconductor gas detection sensor, the gas detection unit located near the front opening is more likely to come into contact with outside fresh air when the door is opened, facilitating the baseline regression of the semiconductor gas sensor.
In one possible embodiment, the gas sanitation module comprises an air outlet located at the rear of the gas sanitation module. On the one hand, this is advantageous in order to avoid problems such as condensation caused by the air flowing towards the door, and on the other hand, the rearwardly arranged air outlet is also advantageous in order to increase the sensorial impact of the gas hygiene module on the user.
In one possible embodiment, a second fan is included that is fixed to the top rear portion of the storage compartment, and an air inlet of the second fan faces the gas sanitation module. Thus, when the second fan is operated, the entry of air into the gas sanitation module is facilitated.
In one possible embodiment, a cold air duct is included at a rear side of the storage compartment, the cold air duct having at least one air outlet at an upper portion of the storage compartment.
In one possible embodiment, the top wall includes a first horizontal section adjacent the front opening, a second horizontal section rearward of the first horizontal section, and an angled section connecting the first and second horizontal sections, the angled section facing the rear wall of the storage compartment; the gas sanitation module is secured to the inclined section. By the inclined design of the box, the gas sanitary module does not need to be specially designed, so that the universality of the gas sanitary module can be enhanced.
In one possible embodiment, the air intake direction of the gas sanitation module intersects the air intake direction of the second fan. This further facilitates the entry of air from the storage compartment into the gas sanitation module.
In one possible embodiment, a door storage box is included that is secured to the door, the gas sanitation module being adjacent the front opening, the door storage box extending into a storage compartment when the door is closed, the air inlet of the gas sanitation module and the door storage box both being spaced apart along a depth of the storage compartment.
One embodiment of the invention relates to a refrigerator, which is characterized by comprising a storage chamber with a front opening; a door to close the storage compartment; a door storage box fixed to the door, the door storage box extending into the storage compartment when the door is closed; and a gas sanitation module comprising a housing and a gas detection unit and/or a purification unit located within the housing; the gas sanitation module is fixed on the top wall of the storage chamber and is close to the front opening; the air inlet of the gas sanitation module and the door storage box are spaced apart from each other in a depth direction of the storage compartment.
In one possible embodiment, both the gas sanitation module and the door storage box at least partially overlap at the height of the storage compartment.
In one possible embodiment, both the gas sanitation module as a whole and the door storage box have a spacing in a depth direction of the storage compartment.
In one possible embodiment, the gas sanitation module comprises an air passage in the housing, the gas detection and/or purification unit being located in the air passage, and a first fan located in the housing to force air from the air inlet into the air passage and through the gas detection unit and out of the air passage from the air outlet. By forcibly introducing air into the air passage in the housing and flowing through the gas detection unit and/or the purification unit, this is not only advantageous for increasing the efficiency of the gas sanitary module, for example for increasing the effective range of influence of the gas detection unit and/or the purification unit, but also for increasing the operating efficiency of the gas detection unit and/or the purification unit.
In one possible embodiment, the gas sanitation module comprises a display unit for displaying at least one gas parameter information of the storage compartment and/or for displaying the operating state of the gas sanitation module.
The construction of the present invention and other objects and advantages thereof will be more apparent from the following description of the preferred embodiments taken in conjunction with the accompanying drawings.

[ detailed description of the invention ]
As shown in fig. 1, the refrigerator 100 includes a storage chamber 101 having a front opening 10 and a door 102 for closing the storage chamber 101.
In one embodiment, the top wall 1010 of the storage chamber 101 may be a top wall of a cabinet 1001 of the refrigerator 100. The storage chamber 101 may extend from an upper portion to a lower portion of the housing 1001, or another storage chamber may be further provided at a lower portion of the storage chamber 101. It should be understood that in an alternative embodiment it is also possible to have another storage compartment above the storage compartment 101.
A plurality of shelves 1011 and drawers 1012 may be provided inside the storage chamber 101. The refrigerator 100 may include a door storage container 103 fixed to an inner side of the door 102 facing the storage chamber 101. There may also be more door storage containers below the door storage container 103, the door storage container 103 being the uppermost door storage container. When the door 102 is closed, the door storage container 103 protrudes into the storage compartment 101, and in this embodiment, the door storage container 103 is adjacent to the inner surface of the top wall 1010 of the storage compartment 10. A gap G is provided between the door storage container 103 and the inner surface of the top wall 1010 to prevent interference between the door storage container 103 and the top wall 1010 when the door 102 is closed.
The refrigerator 100 includes a gas sanitation module 1. Fig. 2 shows a schematic perspective view of a gas sanitary module 1 according to one embodiment of the invention. As shown in fig. 2, the gas sanitation module 1 may include a housing 11, an air passage 12 in the housing 11, and a gas detection unit 13 and an air purification unit 15 in the air passage 12.
The gas sanitary module 1 includes a fan 14 in the air passage 12 to force the air inside the storage chamber 101 to enter the air passage 12 and to be discharged outside the housing 11 after passing through the gas detection unit 13 and the air purification unit 15.
Air inside the storage chamber 101 may enter the air passage 12 through the air inlet 121 located at the housing 11 and be discharged outside the housing 11 through the air outlet 122 located at the housing 11.
The gas detection unit 13 may be arranged to detect at least one gas parameter within the storage chamber 101, such as the presence, content or concentration of one or more gas components. In one embodiment, the gas detecting unit 13 detects a total volatile organic compound concentration (TVOC) inside the storage chamber 101.
The air cleaning unit 15 may include any one or more of an air filter, an ultraviolet sterilization device, an ion generation device, and an ozone generation device. The air filter may be a physical and/or chemical filter, such as an adsorption filter, a catalyzed enzyme filter (e.g., a Pt filter), or the like.
An air purification unit 15 may be disposed in the air passage 12 downstream of the gas detection unit 1 such that the air purification unit 15 is located between the gas detection unit 1 and the air outlet 122.
In the embodiment shown in fig. 2 to 5, the gas sanitation module 1 comprises both a gas detection unit 13 and an air cleaning unit 15. It should be understood that in other embodiments it is also possible that the gas sanitation module 1 has only one of the gas detection unit 13 and the air cleaning unit 15.
The gas sanitary module 1 may comprise a control unit 16 in operative connection with the gas detection unit 13. The control unit 16 is adapted to receive signals from the gas detection unit 13. The control unit 16 is arranged to be adapted to send instructions to the gas detection unit 13.
The control unit 16 may be operatively connected to the fan 14. The fan 14 may be operated or stopped based on instructions from the control unit 16.
A partition 113 may be provided within the housing 11 to divide the housing 11 into the air passage 12 and the mounting chamber 17 for receiving the control unit 16.
The construction of the gas sanitation module 1 according to one embodiment of the invention is described in detail below with reference to fig. 3-6.
The gas detection unit 13 includes a gas sensor 131. The gas sensor 131 may be a metal oxide semiconductor type gas sensor including a semiconductor detection element and a heater to heat the semiconductor detection element.
Fig. 6 illustrates one exemplary embodiment of a gas sensor 131. The semiconductor detection element may include a substrate 1312 provided with an electrode 1311, and a metal oxide 1314 connected to the electrode 1311 as a gas sensing material. A heater 1313 for heating the semiconductor inspection element is disposed at the bottom of the substrate 1312. The volatile organic compounds in the gas interact with the metal oxide 1314 to cause a resistance change in the gas sensor 131, and the total volatile organic compound concentration (TVOC) of the gas is detected based on the resistance change.
In one embodiment, the gas sensor 131 can be selectively placed in a sleep mode and an operational mode. In the sleep mode, the heater 1313 of the gas sensor 131 may be in a power-off state. In the operation mode, after the heater 1313 heats the semiconductor detection element to a predetermined temperature, the gas sensor 131 performs measurement.
In one embodiment, the gas sensor 131 may be in an operational mode under certain conditions, such as periodically in the operational mode, or in the operational mode based on certain triggering conditions (e.g., a door opening to closing, as well as user instructions), returning to a sleep mode after the gas sensor 131 performs a measurement. In an alternative embodiment, the gas sensor 131 may also remain in an operational mode after the measurement is performed, so that the air condition inside the storage chamber 101 may be monitored in real time.
The gas detection unit 13 may further include a temperature sensor 132 and a humidity sensor 133. A temperature sensor 132 and a humidity sensor 133 may also be located within the air channel 12. With this, the gas sanitation module 1 can detect TVOC concentration information, temperature information, and humidity information of the gas when the gas flows through the gas detection unit 13.
The gas sensor 131, the temperature sensor 132, and the humidity sensor 133 may be integrated into an all-in-one detection module.
In one embodiment, the gas sanitation module 1 may correct the detection value of the gas sensor 131 according to the measured gas temperature and humidity, thereby more accurately reflecting the air quality IAQ inside the storage chamber 101.
As shown in fig. 3 and 4, the fan 14 is located within the air passage 12. When the fan 14 is operated, the air inside the storage chamber 101 may be forced to enter the air passage 12 from the inlet 121 of the air passage 12 and exit the air passage 12 from the outlet 122 of the air passage 12 after passing through the gas detection unit 13. The fan 14 may be a vortex fan or other type of fan.
The gas detection unit 13 may be located between the air outlet 122 and the fan 14. The air passage 12 may include an upstream passage 123 between the air inlet 121 and the fan 14 and a downstream passage 124 between the air outlet 122 and the fan 14. The gas detection unit 13 is located in the downstream channel 124.
The downstream channel 124 may have a greater length than the upstream channel 123, thus facilitating the arrangement of the gas detection unit 13.
An air inlet 121 and an air outlet 122 of the air passage 12 may be provided to the housing 11. The housing 11 may comprise a first wall 111 provided with an air inlet 121 and a second wall 112 provided with an air outlet 122, the first wall 111 and the second wall 112 being contiguous. In one embodiment, the first wall 111 and the second wall 112 may be vertically connected.
The first wall 111 is a lower wall of the housing 11, and is located inside the storage chamber 101 facing downward and rearward. The second wall 112 is a rear wall of the housing 11.
The housing 11 may be flat, and the area of the first wall 111 is larger than that of the second wall 112. This advantageously increases the cross-sectional area of the cross-section of the air inlet 111.
The air purifying unit 15 may be disposed in the air passage 12 downstream of the gas detecting unit 1 such that the air purifying unit 15 is located between the gas detecting unit 1 and the air outlet 122.
In the embodiment shown in fig. 3 and 4, the air cleaning unit 15 comprises an air filter 151 and a power-requiring cleaner 152 located downstream of the air filter 151. The purifier 152 may be an ionizer.
A power supply module 153 for supplying power to the purifier 152 may also be provided within the gas sanitation module 1. The power supply module 153 is preferably disposed in the housing 11 in isolation from the air passage 12.
The control unit 16 is adapted to receive the detection values of the gas sensor 131, the temperature sensor, and the humidity sensor from the gas detection unit 13, and to obtain a corrected air quality value IAQ using the detection values of the gas sensor 131 corrected for the current temperature and humidity.
The control unit 16 is adapted to send instructions to the gas detection unit 13, for example the heater 1311 may be powered on or off based on instructions of the control unit 16.
The control unit 16 is operatively connected to the fan 14. The fan 14 may be operated or stopped based on instructions from the control unit 16.
The control unit 16 may be connected to the air cleaning unit 15. For example, the control unit 16 is adapted to send work orders and stop work orders to the air cleaning unit 15.
The control unit 16 may be mounted within the housing 11. The housing 11 may have a mounting cavity 17 therein isolated from the air passage 12, and the control unit 16 is located in the mounting cavity 17. The power supply module 153 may also be disposed in the mounting cavity 17. The installation chamber 17 and the air passage 12 may be partitioned by a partition wall 113 located inside the housing 11.
The control unit 16 and the gas detection unit 13 may be integrated on the same substrate 18. A portion of the substrate 18 where the gas detection unit 13 is provided is located in the air passage 12, and a portion where the control unit 16 is provided is located in the installation chamber 17.
The second housing portion 116 can be provided with a plurality of hooks 1161 to fasten the second housing portion 116 to the first housing portion 115.
In one embodiment, partition 113 may include a first partition 1131 fixed to first housing portion 115 and a second partition 1132 fixed to second housing portion 116. The first partition wall portion 1131 has an opening 1133 to receive the second partition wall portion 1132. A substrate 18 carrying the gas detection unit 13 and the control unit 16 is located in the opening 1133, a portion of the substrate 18 where the gas detection unit 13 is located in the air passage 13, and a portion where the control unit 16 is located in the installation cavity 17. After substrate 18 is fixed to first housing portion 115, second housing portion 116 is assembled to first housing portion 115 with second partition portion 1132 inserted into opening 1133 to form continuous partition 113.
The gas sanitary module 1 may also comprise a display unit 19. The display unit 19 is used to display at least one gas parameter information of the storage compartment 101 and/or to display the operating state of the gas sanitary module 1. For example, the display unit 19 is connected to the control unit 16, and the control unit 16 displays information reflecting the air quality in the storage chamber 101 on the basis of the signal from the gas detection unit 13 through the display unit 19.
In one embodiment, the display unit 19 may be located at the front of the gas sanitation module 1.
The display unit 19 may include a circuit board 191 fixed to the housing 11 and carrying light emitting elements (not shown), and a display panel 192 disposed at one side of the housing 11 and transmitting light at least in a partial region.
The display panel 192 and the circuit board 191 are disposed with a space therebetween. The display panel 192 may be face-coupled to one sidewall 117 of the housing 11. In one embodiment, the display panel 192 is adhered to the sidewall 117. The circuit board 191 extends parallel to the side wall 117 and is fixed in the housing 11 with a spacing from the inner surface of the side wall 117. The sidewall 117 may be provided with a plurality of through holes (not shown) so that the light emitting elements of the circuit board 192 may illuminate the corresponding regions of the display panel 192 through the sidewall 117 according to a signal of the control unit 16.
In another embodiment, at least one gas parameter information and/or display of the operating state of the gas sanitation module 1 of the storage compartment 101 may also be displayed by the main display module of the refrigerator 1. In a further embodiment, the control unit 16 may also transmit at least one gas parameter information of the storage compartment 101 and/or display the operating status of the gas sanitary module 1 to a remote server or a remote terminal to be displayable in a remote display module.
Advantageously, the gas sanitary module 1 may be arranged at the top of the storage compartment 101. For example, the gas hygiene module 1 may be fixed to the top wall 1010 of the storage compartment 101, which is particularly advantageous for the gas hygiene module 1 to more accurately reflect the air quality of the sensitive area of the storage compartment 101. We have found that the height of the gas hygiene module 1 located inside the storage compartment 101 from the ground may be between 1.5 and 1.9 metres, which is advantageous in that the gas hygiene module 1 more quickly and accurately reflects the air quality of the user sensitive area of the storage compartment 101.
As shown in fig. 1, the gas sanitary module 1 can be close to the front opening 10 of the storage compartment 101. Thus, not only is this closer to the user sensitive area, but also when the door 102 is opened, the external fresh air comes into contact with the gas detection unit 11 of the gas sanitation module 1, i.e. the chance of contact between the gas sanitation module 1 and the external fresh air can be increased, which is advantageous for reducing the minimum value of the optimal air of the gas sensor 131 within a predetermined period of time, and in turn, for facilitating the baseline regression of the gas sensor 131, which is advantageous for improving the accuracy of the gas sanitation module 1.
When the door 102 is closed, the door storage container 103 fixed to the rear side of the door 102 is adjacent to the inner surface of the top wall 1010 of the storage chamber 10. In order to improve the sufficient contact between the gas sanitary module 1 and the air inside the storage chamber 101, both the air inlet 121 of the gas sanitary module 1 and the door storage container 103 are distributed with a distance in the depth direction of the storage chamber 101. The depth direction of the storage chamber 101 is the front-rear direction of the storage chamber.
As shown in fig. 1, both the gas sanitary module 1 as a whole and the door storage container 103 have a space in the depth direction of the storage chamber 101. Therefore, the projections of both the gas sanitary module 1 and the door storage container 103 in the height direction of the storage chamber 101 are completely shifted. Accordingly, the projections of both the entire gas sanitary module 1 and the door storage container 103 in the width direction of the storage chamber 101 are also completely displaced.
This is advantageous to avoid that the gas sanitary module 1 arranged close to the front opening 10 is hidden by the door storage container 103 in the air entrapment area and cannot accurately reflect the air parameters and/or the purified air inside the storage compartment 101.
As shown in fig. 1, the refrigerator 100 may include a second fan 20. The second fan 20 may be located inside the storage chamber 101 to agitate air inside the storage chamber 101. The second fan 20 may be disposed at a rear top side of the storage chamber 101. When the second fan 20 is operated, air inside the storage chamber 101 may flow as indicated by an arrow a 3.
To further improve the air quality, the refrigerator 100 may include an air filter 21 fixed to the second fan 20.
In one embodiment, the air inlet 121 is disposed obliquely downward and rearward, and as shown in fig. 1, the first wall 111 provided with the air inlet 121 serves as a lower wall of the housing 11 and is obliquely directed toward the rear wall of the storage chamber 101. Thus, even if the second fan 20 is operated, air can be smoothly introduced into the air passage 12 through the air inlet 121, thereby improving the operation efficiency of the gas sanitary module 1.
Since the air inlet 121 is inclined downward and rearward at the top of the storage chamber 101, the air inlet 121 near the front opening 10 of the storage chamber 101 may be opened toward the main storage area where the shelves 1011, 1012 are provided. This is advantageous in order to increase the detection range and/or the purification effect of the air sanitation module 1 on the air in the vicinity of the main storage area.
The angle a between the air inlet 121 and the horizontal plane may be between 20-45 degrees, preferably the angle a may be between 25-35 degrees. Thus, on the one hand, the outside air entering inside the storage chamber 101 when the door 102 is opened may still significantly affect the baseline regression of the gas detection unit 13, and on the other hand, the air inside the storage chamber 101 may easily enter into the air passage 12 via the air inlet 121. As shown in fig. 1, air enters the gas sanitary module 1 via the air inlet 121 in the schematic direction a 1.
The top wall 1010 of the storage compartment 101 may include a first horizontal section 1031 near the front opening 10, a second horizontal section 1033 located behind the first horizontal section 1031, and an inclined section 1032 connecting the first horizontal section 1031 and the second horizontal section 1033. The inclined section 1032 faces the rear wall 1020 of the storage chamber 101. The gas sanitary module 1 is fixed to the inclined section 1032.
The air outlet 122 may be provided toward the rear of the storage chamber 101. Air exits gas sanitation module 1 from air outlet 122 in the exemplary direction a 2.
The air inlet 201 of the second fan 20 is directed towards the gas sanitary module 1. The intake air discharge direction (a1) of the gas sanitary module 1 intersects with the intake air direction (B1) of the second fan 20.
As shown in fig. 1, the refrigerator 100 comprises a main control unit 30 operatively connected to the second fan 20 and to the gas sanitation module 1. The second fan 20 and the gas sanitary module 1 can receive signals from the control unit 30 and/or send signals to the main control unit 30. The main control unit 30 may control the operation of the second fan 20.
In the above embodiment, the second fan 20 is located inside the storage chamber 101 to agitate the air inside the storage chamber 101. In an alternative embodiment, as shown in fig. 7, the refrigerator 100 includes a cool air duct 25 at a rear side of the storage chamber 101, and a second fan 20 is provided in the cool air duct 25 to forcibly introduce cool air into the storage chamber 7101 to form a forced air circulation between the cool air duct 25 and the storage chamber 101. The cool air duct 25 includes an air outlet 251 at an upper portion of the storage chamber 101. The air outlet 251 may be open toward the front, and open toward the gas sanitary module 1.
The following describes an operation method for the refrigerator 100 according to an embodiment.
A fan (hereinafter referred to as "first fan") 14 of the gas sanitary module 1 located inside the storage chamber 101 is activated to input air of the storage chamber 101 into the air passage 12 of the gas sanitary module 1 to flow the air through the gas detecting unit 13 located inside the air passage 12.
The gas sensor 131 may be switched from the sleep mode to the operational mode before the first fan 14 is activated. This may include activating the heater 1313 to heat the sensing element of the gas sensor 131 to a predetermined temperature.
Thereafter, the first fan 14 is activated to forcibly draw air inside the storage chamber 101 into the air passage 12 and flow through the gas sensor 131 in the operation mode, and the gas sensor 131 in the operation mode performs detection to obtain information on the gas parameter inside the storage chamber 101. In the present embodiment, the gas sensor 131 obtains TVOC information about the inside of the storage chamber 101 to obtain air quality information inside the storage chamber 101.
The information on the gas parameter inside the storage chamber 101 obtained by the gas detection unit 13 may be displayed on at least one display unit. The display unit may be fixed to the housing 11 or integrated in the main display unit of the refrigerator 1. The air quality information may also be transmitted to a remote server or a remote terminal connected to the refrigerator 1 through a network.
Based on the information about the air quality inside the storage chamber 101 measured by the gas detection unit 13, the refrigerator 1 may start a purging procedure. The decontamination procedure may be initiated automatically or manually by the user. In a cleaning process, the air cleaning unit 15 located in the air passage 12 and/or the air cleaning unit located in the storage chamber 101 or the cold air passage communicating with the storage chamber 101 is activated to clean the air in the storage chamber 101.
In order to more accurately detect the quality of air inside the storage chamber 101, the second fan 20 located inside the storage chamber 101 is activated to agitate the air of the storage chamber 101 or to form a forced air circulation between the storage chamber 101 and a cooling air duct. The first fan 14 and the second fan 20 may be activated simultaneously, or the second fan 20 may be activated prior to the first fan, or the first fan and the second fan may be operated alternately. In one embodiment, the operation is stopped or intermittently operated after the second fan is operated for a predetermined time.
In the embodiment in which the air hygiene module 1 comprises an air filter 151 located in the air channel 12, the air hygiene module 11 starts to purify the air when the first fan 14 is operated, the air entering the air channel 12 flows through the air filter 151, i.e. the first fan 14 is operated.
Where the air sanitation module 1 includes a purifier 152 requiring power, activation of the purifier 152 may be initiated based on a time period, user input, or the result of the gas detection unit 13. When the scrubber 152 is activated, the first fan 14 is operated to enhance the scrubbing effect.
In an embodiment including both the air purification unit 15 and the gas detection unit 13, the first fan 14 may be operated by the air purification unit 15 and also by the gas detection unit 13. For example, when the first fan 14 is operated, only one of the air cleaning unit 15 and the gas detection unit 13 performs the operation, or both perform the operations simultaneously or sequentially.
In the embodiment of the present invention, the air inside the storage chamber 101 is easily introduced into the air sanitation module 1, thereby contributing to the improvement of the gas detection accuracy and the detection range, and/or the improvement of the air purification effect.
The various embodiments described in connection with fig. 1-7 may be combined with each other in any given way to achieve the advantages of the invention. In addition, the present invention is not limited to the illustrated embodiments, and other means than the illustrated means may be used in general as long as the same effects can be achieved by the means.
