Description

Description: TECHNICAL FIELD The present invention relates to a hot water supply device for a jar pot having a pump using an electromagnetic pump or an electric motor.

2. Description of the Related Art Conventional jar pots of this type include an electromagnetic pump or a pump using an electric motor, and hot water can be discharged by simply turning on a switch.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention However, in these hot water dispensers for jar pots, when a switch is operated to perform hot water discharge, suddenly a large amount of hot water with the full capacity of the hot water dispenser suddenly pops out, and an empty teacup or a teacup Since it is poured into the cup, the splash of hot water at that time may reach the user's hands, which is very dangerous.

It is an object of the present invention to provide a hot water supply device for a jar pot that solves such problems.

Means for Solving the Problems In order to solve the above problems, the present invention provides a first switch for turning on and off the hot water output means, and a second switch for switching the amount of hot water output. Switch is operated by a common push button, and while the stroke for pressing the push button is small, only the first switch is operated and the amount of hot water discharged by the hot water discharging means is small, and the push button is further pressed. When the stroke is increased, the second switch is also switched to increase the amount of hot water discharged by the hot water discharging means.

With the above-mentioned configuration, the common push button for operating the first switch and the second switch can be tapped little by little at first so that the hot water can be tapped little by little. You can increase the amount of hot water discharged by pushing deeply.

Embodiment One embodiment of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a sectional view of a jar pot according to an embodiment of the present invention, in which 1 is a container, 2 is an outer casing, 3 is a lid, 4 is tapping means, and this tapping means 4 is an electric motor 5.
And a pump 6 driven by the electric motor 5. Reference numeral 7 is a first switch for turning on and off the electric motor 5, 8 is a second switch for switching the strength of rotation of the electric motor 5 to switch the amount of hot water discharged,
Reference numeral 9 is a common push button for operating these two switches 7 and 8.

FIG. 2 is a circuit diagram for controlling the electric motor 5. In FIG. 2, 5a and 5b are field coils and an armature that constitute the electric motor 5, and the field coil 5a has an intermediate tap. 5c is provided, and the second switch 8 is connected to the intermediate tap 5c and the termination 5d.

Next, the operation of the above configuration will be described. Figure 3a,
b and c are sectional views showing the mechanism of the first switch 7, the second switch 8 and the push button 9, and FIG. 3a shows the case where the push button 9 is not pushed at all, In this case, the contacts 7a, 7b, 8a, 8b of the respective switches 7, 8 are arranged so that the first switch 7 is turned off and the second switch 8 is turned on. At this time, since the first switch 7 is off, the electric motor 5 does not rotate. FIG. 3b shows a case where the push button 9 is slightly pushed in. In this case, before the pushed push button 9 reaches the movable contact 8a of the second switch 8, the first switch 7 is pushed. The positions of the first switch 7 and the second switch 8 are shifted so that the movable contact 7a is pushed downward to come into contact with the fixed contact 7b to be turned on. In this state, the electric motor 5 rotates,
Since the second switch 8 is still on, the intermediate tap 5c and the terminal 5d of the field coil 5a are short-circuited, and as a result, the rotation of the electric motor 5 is weakened, so that the pump 6 pumps hot water. Is small. When the push button 9 is further pushed from this state to the state shown in FIG. 3c, the second switch 8 is also turned off, and as a result, the field coil 5a becomes effective in the total number of turns. The rotation is strong and therefore the amount of hot water pumped by the pump 6 increases.

EFFECTS OF THE INVENTION As described above, according to the present invention, the first switch for turning on and off the hot water discharging means, the second switch for changing the amount of hot water discharged by the hot water discharging means, and the turning on and off of these two switches When the stroke for pressing the push button is small, only the first switch is operated and the amount of hot water discharged by the hot water discharging means is small, and the stroke for pressing the push button is large. Since the second switch is also switched so as to increase the amount of hot water discharged by the hot water discharging means, when the hot water is operated, the hot water is first discharged little by little, so that the safety can be ensured, and thereafter, You can choose the amount of hot water that comes out, and as a result, you will no longer be splashed with hot water or burned with overflowing hot water. Therefore, it is possible to provide a safe and easy-to-use jar pot hot water discharge device.
