Description

[Detailed Description of the Invention] This invention relates to a timer that allows a fan to operate for a desired time so that the wind from the fan can help you sleep cool on nights when it is hot and difficult to sleep, such as on summer nights. .

With conventional timers that operate the fan for a certain period of time and then turn off the fan, if the above time is short, the fan may stop before you can fall asleep, making you feel hot and uncomfortable. On the other hand, if you sleep for a long time, your body will become unstable and your body will become too cold during the paradoxical sleep period, which can cause you to catch a cold or get cold in bed.

Therefore, the present invention aims to eliminate the above-mentioned drawbacks.
To provide a timer that can operate an electric fan in a state that allows you to fall asleep very comfortably and prevents damage to your health.

The drawings showing the embodiments of the present application will be described below.

First, a seventh embodiment shown in FIGS. 7 to J will be described. In the circuit diagram of FIG. 1, l is the well-known 100
V AC power supply, 2 indicates the electric fan motor, volume [314

Next, in the timer U, ν indicates a timer motor, L(, 14, 15d indicates a first switch, a second switch, and a third switch, respectively) as an example of a clock mechanism.

Next, the relationship between the switch and the cam in the above timer will be explained. Reference numeral 17 denotes a main shaft, which can be manually rotated in either a clockwise or counterclockwise direction, and can also be rotated counterclockwise in the figure by a clock mechanism (the timer motor 12 or a well-known spring-type clock mechanism). It is designed to be able to rotate clockwise at a constant speed (inconstant speed is also acceptable).

17a indicates a drive piece fixed to the main shaft 17. The plate is a first cam, which has two elements arranged next to each other, namely a first element 19 and a second element 19. Reference numeral 21 denotes a fitting hole provided in the cam direction, in which the driving piece 17a is left so that the rotating force of the main shaft 170 is transmitted to the cam direction. B is a second cam, which is designed to rotate together with the first cam slide. This second
The cam η also has a first element B and a second element arranged side by side. Each of the cam elements in the above-mentioned cam assembly 22 has its outer circumferential surface as a cam surface, and has a plurality of high steps,
It has a middle section, a low section, etc. The high-level portions are indicated by the numerals with the subscript a added, the middle portions are indicated with the subscript ``s'', and the low-level sections are indicated by the numerals with the subscript C added. In the second cam η, reference numeral 5 indicates a neutral operating portion, which is composed of a high step portion Z3B of the first element and a high step portion 24a of the second element. The section indicates an intermittent switching control section, which is composed of a low step section 23c of the seventh element and a low step section 240 of the second element. η indicates a first intermittent opening/closing control section, which is composed of a low-stage section 23C of the first element and a high-stage section 24& of the second element U. 2 indicates a second intermittent opening/closing control section, which is composed of a middle section 23b of the first element n and a lower section 24c of the second element. Next is an intermittent cam, which is connected to the clock mechanism so as to rotate at a significantly faster speed than the first or second cam slide 22. This intermittent cam (equipment) is a first element 31, a second element part, and a third element arranged in the width direction.
It has all the elements.

Next, a switch which is made to follow the seventh cam will be explained. This switch is a contact plate.

It has 36 parts. a, 38 are contact plate parts, 36
These are contacts provided at the tip of the contact plate, and these are formed by deforming the tip of the contact plate into a bulging shape as shown in the figure. a
4o and 4o respectively indicate contacts constructed by bending and forming the tip end of a contact plate portion as shown.

The contact 37.3g constitutes the seventh switch rib, and the contact O, 40 constitutes the second switch 14.

A driven part is attached to the middle part of the contact plate part, is made of an insulating material such as synthetic resin, and is opposed to the cam surface of the second element.

Next, the switch (third switch 15) K which is made to follow the second cam ρ will be explained. This switch has first to third contact plates 45, 46, which are arranged in parallel with each other in an overlapping manner.
It consists of 47 parts. These contact plates have contacts 45a, 46a, 47& which are brought into contact with and separated from each other.

Also, the free ends of those contact plates are
Also, the third part is formed wide, and the first contact plate has a driven part 45b which follows the first element 31 in the intermittent cam I, and the second contact plate has a second element clear part. A driven portion 46b is formed to follow the third element, and a driven portion 47b is formed on the third contact plate C to be driven by the third element. The string is attached to the middle part of the second contact plate.The operated part is made of an insulating material and is connected to the first part of the second cam.
It is opposed to the outer peripheral surface of element B. 49 companies 3rd contact plate C
The second element of the second cam is necessarily opposed to the second element of the second cam, and is made of an insulating material. In FIG. 7, the gloss indicates a manual operation knob attached to the main shaft 17. In this FIG. 1, the first and second
A circular chart showing the relationship between the rotational position (rotation angle) of the cam and the energization state of the fan motor and the indicated position of the knob are shown in correspondence.

With the above configuration, when the knob W is set at the position shown in Figure 1 (A), each of the first to third switches will be in the state as shown in the circuit diagram of the same figure or Figure 1 (A). , the timer motor does not operate, and the fan motor 2 also does not operate.

If you want to operate the fan continuously, set the knob ω to the section shown in Figure 1 (b). Then, the circuit diagram in the same figure and the first rF
l! As shown in J (b), the second switch 14 closes and current flows through the electric fan motor 2. Since the electric current to the motor 2 is applied to the terminal selected by the select switch 6 as well known in the art, it is possible to obtain the desired strength of wind.

Next time, when you want to use a fan to sleep, set the knob at any point in the section shown in Figure 1 (c).

Then, the seventh and second switches 13 and 14 are closed, respectively, as shown in FIG. Therefore, the timer motor rotates, and current is also supplied to the electric fan motor 2 via the select switch 6, so that a desired strength of wind can be obtained. In this state, the rotation of the timer motor ν causes the cams 22 to rotate in the directions of the arrows (the knob ω also automatically rotates to the left in FIG. 7). In addition, the intermittent cam (support) rotates to the right in Fig. J at a faster speed than the above-mentioned cam N. Even if the cam rotates, the operated part 49 of the switch comes into contact with the neutral operation part 5 of the cam 4, so the switch does not switch or open/close.

In this state, the sleeper gradually begins to fall asleep after about 20 minutes, as shown in Figure 2.
Eventually, the sleepiness becomes deeper and you reach a deep sleep phase. The fan operates in the above-mentioned state until about the time when you are about to enter the deep sleep period (
(for example, about the first minute after the start of operation).

Eventually, the knob ω will be in a state pointing to the section ) in FIG. The cams 18, 22, and 30 are also rotated, and the switches operated by them are in the state shown in FIG. 1). That is, the second switch 14 is open and only the seventh switch U is closed, and when the switch is closed, the operated parts 48 and 41 are opposed to the intermittent switching control parts. In this state, the intermittent cam rotates in the direction of the arrow as shown in Fig.
, 47a is connected, neutral state, and contact 4 is connected again.
The state in which 5m and sa are connected is repeated (eg, 3 minutes, 2 minutes, 3 minutes, joining, and 3 minutes each). In other words, the switch operates intermittently. Then, as is clear from the circuit diagram in Figure 1, the electric fan's motor 2 has three functions: one for supplying current to the terminal that generates the "medium" wind, one for stopping the current, and one for "stopping".
A state is reached in which the supply of current to the terminal that generates the "weak" wind and the interruption are repeated in sequence. Accordingly, the motor 2 operates accordingly, and the person facing the electric fan is repeatedly exposed to moderate wind, no wind, or weak wind. This state continues throughout the entire range of tx tx during the first deep sleep period.Next, the knob ω points to the section (e).

In this case, the cam holder 22 rotates further, and the switch driven by them becomes in the state shown in FIG. 1 (e). In other words, the switches 13 and 14 remain in the same state as described above, while the operated part 49 of the switch (2) faces the first intermittent opening/closing control part I. In this state, the contact plate 47 remains pushed up, so even if the intermittent cam field rotates, the contacts 46a and 47a do not come into contact with each other, and the cam rotates as shown in the figure. Along with the movement, a state in which the contacts 45B and 40a are connected (for example, for 3 minutes) and a state II in which they are separated (for example, for 7 minutes) are alternately repeated. In this state, current is intermittently supplied to the terminals of the electric fan's motor 2 that cause the draft. Therefore, the motor 2 operates in this manner, and the person facing the electric fan is repeatedly exposed to wind or no wind.

This state 1lIa continues from the end of the first deep sleep period to the paradoxical sleep period until the paradoxical sleep period approaches its end.

If more time passes in the above state, the picking group will be in a state pointing to the section shown in Fig. 7 (f). In addition, the cam 22 is further rotated, and the switch that is driven by them is in the state shown in Fig. 1 (f). That is, the switches 13 and 14 remain in the same state as described above, while the switch L5 is operated by the operated section 49.
is in a state where it faces the second intermittent opening/closing control part Z, so as the intermittent cam I rotates as shown in the figure, the contacts 46&,
47& repeats a state of contact (for example, J#) and a state of separation (for example, 7 minutes). In this state, as is clear from the circuit diagram, current is intermittently supplied to the terminals of the electric fan motor 2 that produce a weak breeze. Therefore, the fan 2 operates in this way, and the person facing the fan is repeatedly exposed to weak wind or no wind. This state continues until the end of the paradoxical sleep period and the middle of the next deep sleep period.

When the above condition is completed, the knob will eventually become shiny as shown in Figure 1 (G).
It will point to the location shown in . Also, each cam holder rotates to the state shown in Fig. 1), and the switches 14 that are driven by them are all opened. Therefore, the supply of current to the motor 2 of the electric fan is stopped, and the electric fan is brought into a stopped state, and the supply of current to the timer motor is also stopped.

In this way, the timer U operates and the power supply to the electric fan motor 2 is controlled accordingly, so that the sleeper is able to sleep comfortably in a cool state and without feeling cold in bed if he or she has a cold. I can do it.

Next, when it is desired to operate the electric fan continuously for a desired time (for example, during the day), the knob is set at an arbitrary point in the section (a) in FIG. 1. In this state, both switches i3 and 14 are closed, and the switching operation of switch L5 is stopped by the neutral operating portion 5 of the cam ρ, as shown in FIG. Therefore, as is clear from the circuit diagram in FIG. 1, the fan motor 2 is continuously energized to the terminals that produce the wind selected by the select switch 6, and the timer motor is also energized. , they all rotate. As a result, the person facing the electric fan continues to receive the desired wind. If time continues in this state, the knob ω will sequentially move to the left in FIG. 1, and will eventually reach the state shown in (A). In this state, as described above, the cam and the switch driven by the cam are in the state shown in FIG.

Next, FIG. 9 and FIG. 1O show a different embodiment of the present invention, in which the structure of the select switch and the electrical wiring are the same as those described above.

In this example, the select switch is composed of six switch elements 1 to 6, and the inner symbols of these switch elements, ie and ku, edict and ki, and 茄 and kin, operate in conjunction with each other. It is supposed to be done. and switch 51
, 52 is closed, a strong wind is obtained, and switch 53.6 is closed.
When 4 is closed, medium wind is obtained, and when switch 56 is closed, weak wind is obtained.

With this kind of configuration, if you turn on the fan when you are trying to fall asleep, and set the select switch to strong wind, the strong wind will start as shown in Figure 1θ (G). Continuous, strong winds, pauses, medium winds, pauses,
There is a state in which strong winds are repeated, then a state in which strong winds and pauses are repeated, and finally a state in which moderate winds and pauses are repeated, and then the operation is stopped. Also, when the select switch is set to medium wind, first medium wind continues, then medium wind, pause, weak wind, pause are repeated, then medium wind, pause is repeated, then weak wind, pause. The process is repeated and finally comes to a halt. Also, when the select switch is set to weak wind, the weak wind will be continuous at first, then the weak wind and pause will be repeated at short time intervals, and then the weak wind and pause will be repeated for a long time. It is performed at intervals (with long pauses) and eventually comes to a halt.

It should be noted that parts that are considered to have the same or equivalent structure as those in the previous figure in terms of function are given the same reference numerals as in the previous figure with the letter e, and redundant explanations are omitted.

As described above, with this invention, when you are trying to sleep on a hot and uncomfortable night, you can simply start this timer before going to bed, and the fan will turn on to help you fall asleep comfortably and without harming your health. Moreover, after falling asleep, the fan can be turned off to save energy and to prevent damage to health.
