Description

TECHNICAL FIELD The present invention relates to an electric water heater with a cooler equipped with an electric water heater and a vacuum double bottle cooler.

2. Description of the Related Art Conventionally, an electric water heater equipped with a heat-retaining device, a heat-retaining device, and a heat-retaining function using a mahobin that uses a vacuum double bottle made of glass or stainless has been widely used. Generally, these mahobins and electric water heaters are generally used to keep hot water in mahobin, to keep cold water such as cold tea and barley tea in summer, and to use stainless steel mahobin for leisure. It is used to keep warm and cool. Further, in the electric water heater, a boiling type has become mainstream in recent years, and it is mainly used for keeping the temperature of hot water, and each of them is generally used alone.

However, as shown in Japanese Utility Model Laid-Open No. 58-86029 (see FIG. 7), an electric water heater with a cooler has been devised, which is a combination of the electric water heater and a mahobin whose main purpose is to keep cold. In the device of this invention, the outlets (water) from each container are facing in opposite directions, and if you want to use both hot water and water at the same time, you need to bring a cup or teapot to each outlet. There was, and it was inconvenient.
Further, since the inner stopper is also used on the side of the electric water heater that constantly performs the water heating, there is a problem that the life of the inner stopper is shortened due to the influence of boiling water or steam generated. In addition, it is necessary to open the lid for water supply or drain hot water and then remove the inner plug each time, which is inconvenient.

Problems to be Solved by the Invention According to the above-mentioned conventional technology, when a mahobin or an electric water heater is used independently, it takes space, which is inconvenient in a small kitchen in Japan. Yamabo bottles are generally used for heat retention, and when cold water etc. are needed, use a plastic container containing water in a refrigerator and keep it cool, or use a cup of ice taken from the freezer. It is necessary to open the refrigerator or freezer each time, for example, to put it in a bottle and to use it after cooling it with tap water, and to do so, especially when eating, according to the needs of the family. It was troublesome.

Further, if the device as disclosed in Japanese Utility Model Laid-Open No. 58-86029 can be realized, the above problems can be solved to some extent, but as shown in the prior art, tap water (water) outlet from each container Are facing each other, and if you want to use both hot water and water at the same time, you need to bring a cup or teapot to the side of each outlet, which is not only convenient, but always Since the inner stopper is also used on the side of the electric water heater for boiling water, as with the mahobin side, the effect of boiling water and steam generated will cause problems such as shortening the life of the inner stopper and further water supply. It was very difficult to use because it was necessary to remove the inner plug each time after opening the lid when draining hot water.

Means for Solving the Problems The present invention has been made to eliminate the above-mentioned drawbacks,
On the side of the electric water heater, tap water is discharged from below the inner container via a water pipe, and the water outlet on the electric water heater side and the water outlet on the mahobin (cooler) side are located in the middle part between the two.
That is, the front panel is arranged at the front nose portion, and the inwardly curved front panel made of plastic is provided at the center of the front surface of the main body. Further, a body ring is provided on the shoulder portion of the body, a mounting metal fitting is fixed to this, a holding metal fitting is attached to this mounting metal fitting, and the container is pressed and fixed to the main body ring by this pressing metal fitting.

Function With this structure, the inner plug is eliminated on the side of the electric water heater, so the boiling water and the generated steam have no effect on the inner plug, which is not only advantageous in terms of life. Since both hot water outlets (water) are located in the front nose part which is the middle part between them, both hot and cold water can be obtained by pressing the air pump on the desired side at a fixed position. It is now possible to easily obtain hot or cold water whenever you want. In addition, since the front panel below the nose portion and in the center portion is curved inward, a large teapot or the like is easy. Further, it becomes possible to stably hang and fix the vacuum double container.

Further, if the inner containers of the both are configured to be slightly vertically long, the floor area can be reduced and the containers can be compactly assembled.

The operation of this embodiment is that when water is poured into the inner container 2 on the left side of the electric water heater, the thermostat 5 for water heating works to energize the heater 3 to boil the water. When boiled, steam is generated, and the plug 22 is opened through the hole in the back cover 19.
Steam flows from the hole 23 in the direction of the arrow in FIG. 3, flows into the steam vent pipe 20 and the steam pipe 59, and is discharged from the steam hole 60. At this time, the temperature of the steam sensor 7 gradually rises due to the steam, and when boiling is detected, the relay (not shown) switches the power supply to the warming heater 4, and the warming sensor 6 keeps the temperature at 90 ° C or higher. . When it is desired to reboil the warm water, the reboil key 71 is pressed to switch to the heater 3 by the relay to boil the water.
When the steam is again boiled to generate steam, the steam sensor 7 detects boiling and switches to heat retention as in the above.

The hot water that has been kept warm is switched to the “out” side by pressing the push plate 55, and when the air pump 51 is operated, the pushed air is sent into the inner container 2, so that the hot water is stored in the inner container. 2 Container pipe 8, U-shaped packing 11, water pipe 12, stopper holder from the hole 10 provided in the bottom surface portion 9
14, flows through the sprue pipe 16 to the sprue 17, and is poured into a container such as a teapot 65. At this time, since the central portion of the front panel 47 is curved to the inside of the main body 1, the front panel 47 can be easily poured into a container having a large diameter.

In addition, by putting water or cold water containing ice pieces into the other cool container 27, by the action of the vacuum double stainless steel bottle,
Like mahobin, it keeps cold water cool. Also, if hot water is poured instead of cold water, it is possible to keep the temperature the same. This cold water or warm water is the same as in the case of the electric water heater, the push lever 55 is pushed by switching the stop lever 56 to the "out" side, and when the air pump 52 is operated, the pushed air is removed. Since the cold water or hot water flows into the inside stopper 30 as shown by the arrow through the inside stopper 30 as shown by the arrow in FIG. 4, the cold water or hot water flows through the inside stopper 30 through the pipe 31, the tip portion 32, and the hole 33, and the outlet pipe 34. It flows and is poured into a container such as a cup. At this time, the water discharge pipe 34 is arranged in the nose portion 70 like the spout 17, so that it can be freely obtained by changing the push plate 55 that is pushed at the same position regardless of whether hot water or cold water is poured and the same feeling. It is a thing. Since the cold storage container 27 is the same as a mahobin, it is impossible to keep cold or keep warm for a long time. For example, in the case of cold keeping, it is necessary to add ice pieces on the way.

Further, in the present embodiment, the case of the electric water heater side being a non-microcomputer type has been described as an example, but a temperature sensor such as a thermistor is attached to the bottom of the inner container 2 to detect the hot water temperature and use the microcomputer for heating. The type that controls the water temperature by controlling 3 or the steam sensor detects boiling, and the temperature of the water is detected by a temperature sensor such as a thermistor attached to the bottom of the inner container 2, and the heater 3 is controlled by the microcomputer. Any type that controls the temperature of the hot water may be used.
