Description

[Detailed description of the invention] 1 branch 1 (I field) This invention relates to a liquid heating container.

<Prior art> Conventionally, a medium container was placed inside an outer coove, and a heating element was placed at the bottom of the medium container. It is also known as a so-called electric container or liquid heating container.

This J, J3 is in the eel electric pot (ha, water father [yo fever?9
Because the heating element was layered while immersed in water, the watertight structure had to be multi-layered to ensure electrical insulation, and it almost looked like a humanoid. Although the heating element was attached to the outside of the inner container, there was a problem in terms of thermal efficiency compared to direct IJII heat due to indirect heating.

Considering this situation, it is possible to install a lamic heater integrally with the 71 output vizo, or to simply install a heating covering function to increase the temperature. Detect and
IjG to the reramic heater by detecting the dry state of Ashi audience with the set thirst level of 1- or less, and the dry state of Shuibatake Qian crystal? I had a problem with q not being able to control h.

<Purpose> This May and January +, L, 1 JL heat bottle made by Hiramic 71
Watertight 414 structure by being integrated with the output vibrator.
Achieved miniaturization due to IlI prefecture and I4't, and also has excellent electrical insulation and T11 heat 111. As a result, the photothermal element can be installed inside the inner container, and heating In order to improve the efficiency, however, by integrating the temperature control into the ceramic dispensing vibrator, the liquid thirst sensing ability is improved.

There are 4 connected in 0 rows.

The operation of the electric box 1 with the above configuration is as follows:
be.

Pour water into the vacuum second hand 111i (21) while listening to the lid unit (6), and then insert the magnetic plug (14) into the socket 1-(13). It can be heated and raised in temperature.

Here, the ceramic heater (ri) is in )8 and +1
ii In I heating is performed, so the heating efficiency is good, and furthermore, the heater is formed by integrating the 71 output barb (3) with the 414 Hiramic pipe.
It can protect and insulate from the outside, and has good thermal conductivity while maintaining electrical insulation and 1114 heat I11 well. j and be safe! It is possible to raise I='i and avoid improving the heating rate. When the temperature inside the vacuum bottle (2) reaches a predetermined temperature, the relay coil (75) is energized to set the f:i closing terminal (16) to 0.
Then, turn off the power to the ceramic heater,
As the temperature of the lagoon decreases, the power to the ceramic heater (5) will be restarted.

) can be taken out to the outside through the pouring vibrator (3) 33 and the pouring vibrator (4).

So, if you take out most of the water inside the vacuum double bottle (2), or forget to put water into the vacuum double bottle (2), the ceramic heater (5) will turn on. The dry cooking condition occurs and the internal temperature rises abnormally (over 100 degrees Celsius), so turn on the dry cooking prevention L sensor (53). ”Iru (79) is normally closed: Ryo (80) is 01-
Since F1v is raised, electricity can be prevented from being applied to the ceramic heater (5), and the dry heating state can be turned off. Here, the temperature control sensor (5 (1) and the dry-cooking prevention sensor (53) are both connected to one ramic) output pipe (3).
Since it is integrally formed with C, electrical insulation and heat resistance are 1/11.
Excellent heat conduction 11, hot water temperature sensing 1'1. It is possible to spell fihi high. In addition, relay coil (79) t, Li~
Maintaining the power status, the internal 1 item 1 quality has decreased and the rb reramic heater (5) is energized (i; (tl status is changed to 11).

In other words, it is reported that the ceramic heater (5) was energized even though the thirst level was low.According to the second embodiment,
i+n! The la control unit (50) is equipped with a ceramic heater (
5) Turn the power back on to the upper pump and turn on the tIA, so while it is possible to take out the water, use the control senna (50) to restrict the energization to the heater (t)). When the temperature of the water reaches a predetermined temperature close to boiling point (>H), take out the hot water (11 h times), and then (to prevent dry cooking! According to i3), it is possible to detect the dry cooking state and prevent dry cooking (11).
Moreover, once the dry cooking condition is detected, unless the switch (84) is operated, the ceramic heater (1
This provides long-term effects such as being able to maintain the Tfi cutoff state.

<Effects> As described above, in the liquid heating container of the present invention (which has an inner container inside the outer case and an RL" output vibrator inside the inner container), the pouring pipe is made of ceramic. It is characterized by the fact that the heater J, and the hinge are integrally installed at the fixed position of the pouring pipe, and the heater J3 and temperature sensor are made of L lamic. By integrally forming the spout pipe (protected and insulated from the outside, it has electrical insulation properties,
It maintains good heat resistance and thermal conductivity, and simplifies the watertight structure by eliminating the need for a special watertight structure. By directly heating the ceramic heater by always keeping the liquid contained in it, it is possible to increase the heat resistance, and also to constantly maintain the temperature. Because it is immersed in liquid, the temperature sensitivity 11L can be increased, and the RL-exit vibrator also serves as a heater and a means of taking the warmth, Q,! t) I'l's 1 method must be taken, but 1J1 has the effect of simplifying the configuration and b) achieving miniaturization and eaves expansion.
