Description

[Detailed Description of the Invention] [Industrial application field and outline of the invention] The present invention relates to a hot water cooker for cooking vacuum-packed food or the like with hot water in a hot water tank, and a space in the hot water tank of the hot water tank The temperature distribution in the hot water tank can be positively promoted without narrowing the temperature distribution.

[Prior Art and Problem] In a kitchen or the like of a restaurant, a vacuum-packaged processed food may be warmed in a hot water-type cooking device and then served for serving.

A heater is attached to the bottom wall of the hot water bath in the ordinary hot water bath type cooker, and the heater is heated by the heater to about 40 ° C. to 97 ° C. Warm food.

However, in the above-mentioned conventional one, since the food is heated by the hot water in the hot water tank which causes natural convection, it is difficult to make the temperature distribution in the hot water tank uniform, and each food item placed in a different place in the hot water tank is Even if it is heated for a standard time empirically determined in advance, it may not be warmed to the same temperature. Therefore, in such a case, there is an inconvenience that the quality of the finished dish varies.

Therefore, in order to solve the above-mentioned inconvenience, it is possible to provide a stirring blade in the hot water tank to forcibly stir the hot water tank, thereby positively making the temperature distribution in the hot water tank uniform.

However, in this case, since the stirring blades occupy a part of the space in the hot water tank, there is a problem that the food storage space in the hot water tank cannot be narrowed to efficiently use the food.

The present invention has been made in view of the above point, and in a "boiler cooker that heats food by adding food to hot water in a hot water tank with a heater attached to the bottom wall", An object of the present invention is to positively promote uniform temperature distribution in the hot water tank without limiting the food storage space.

[Means] The technical means of the present invention for solving the above-mentioned problem is to "provide a discharge port and a suction port which are opened on the bottom wall in the hot water tank, and provide a water passage connecting the discharge port and the suction port outside the hot water tank. It is formed and a circulation pump is arranged in the water passage, and the arrangement interval between the discharge port and the suction port is set to be large ”.

[Operation] The above technical means operates as follows.

When the heater and the circulation pump are operated, the water in the hot water tank heated by the heater is sucked from the suction port in the bottom wall of the hot water tank and ejected from the discharge port in the bottom wall of the hot water tank by the action of the circulation pump. The water in the hot water tank is agitated by the jetting force of the jetted water at this time. This promotes uniform temperature distribution in the bath.

[Effect] The present invention has the following unique effects.

． Since the water passage and the circulation pump that positively promote uniform temperature distribution in the hot water tank are arranged outside the hot water tank, the food storage space in the hot water tank is not limited, and the hot water tank is efficiently Available for

． Since the discharge port and the suction port are opened on the bottom wall of the hot water tank, it becomes easy to make the temperature distribution in the hot water tank uniform. That is, in the case where forced agitation is not performed, an isothermal layer having a constant temperature at the same water depth is formed in the hot water tank. However, the water jetted from the discharge port formed on the bottom wall of the hot water tank has the above isothermal layer. As a result, the temperature in the hot water tank can be made uniform so that the temperature in the hot water tank can be made more uniform than in the case where the discharge port is formed on the side wall of the hot water tank.

[Embodiment] Next, an embodiment of the present invention will be described with reference to the drawings.

As shown in FIG. 1 and FIG. 2, the bottom wall (11) of the rectangular parallelepiped water bath (1) covered with the opening / closing lid (8) has a pair of diagonal corners near the corners. Located outlet (13)
And a suction port (14) are formed, and a circulation pump (2) is provided below the water bath (1) in the appliance body (B) and connects the discharge port (13) and the suction port (14). A waterway (3) is formed. A drainage channel (4) having a drainage cock (41) is branched from the upstream side of the circulation pump (2) in the water passageway (3).

A heater (5) is attached to the outer bottom surface of the hot water tank (1), and the heater (5) is covered by a cover (52) having a heat insulating material (51) therebelow. It is held in contact with the bottom wall (11), and further, at the discharge port (13) formed in the bottom wall (11) of the hot water tank (1), a hot water temperature sensor formed by a thermistor ( 6) is provided. In addition, the basin (19) is loaded at the bottom of the water bath (1).

The circulation pump (2) and the hot water temperature sensor (6) are electrically wired as shown in FIG. 3, and the control circuit is operated by operating the operation switch (71) provided on the front surface of the appliance body (B) or the like. Electricity is supplied to (61).

The output of the hot water temperature sensor (6) and the output of the hot water temperature setting device (62) composed of a variable resistor are adapted to be compared by a comparator (55), and the output of the comparator (55) is It is applied to the transistor (66) that energizes the heater relay (65). The heater contact (651) of the heater relay (65) turns on / off the heater (5) for heating the bath.

Further, the circulation pump (2) is driven and stopped by opening and closing the output contact (211) of the pump relay (21) which is energized by turning on the operation switch (71).

In this case, a partition net (18) as shown in FIG. 4 is placed on the slat (19) as shown in FIG. 1, and then the hot water tank (1) is placed in a water storage state and a hot water temperature setting device. After setting the hot water temperature at (62), turn on the operation switch (71). Then the pump relay
(21) is energized, its output contact (211) is closed, and the circulation pump (2) starts to operate.

Immediately after turning on the operation switch (71), the hot water temperature sensor (6)
Since the water temperature detected by is lower than the set temperature of the hot water temperature setting device (62), an "H" signal is output from the comparator (55). Then, the transistor (66) is turned on and the heater relay (65) is energized, whereby the output contact (651) of the heater relay (65) is closed and the heater (5) is caused to generate heat. Bathtub (1)
The inside is heated.

When the inside of the hot water tank (1) is heated, the water in the hot water tank (1) is forced to circulate between the hot water tank (1) and the circulation pump (2) by the action of the circulation pump (2). Will be
The circulating water agitates the water in the hot water tank when it is ejected from the discharge port (13) opening on the bottom surface of the hot water tank (1).
The temperature inside the hot water tank (1) is raised to a set temperature while the temperature distribution inside (1) is made uniform.

Eventually, when the temperature in the hot water bath detected by the hot water temperature sensor (6) rises to the temperature set in the hot water temperature setting device (62), the output of the comparator (55) changes to the "L" state and the heater (5) turns on. Although in the OFF state, the circulation pump (2) continues to operate and continues the stirring operation of the water in the hot water tank (1). Then, when the inside of the hot water tank (1) is cooled, the heater (5) is made to generate heat again by the output of the hot water temperature sensor (6), and the hot water tank is repeatedly turned on and off.
(1) The internal temperature is maintained at a constant temperature, and the vacuum-packed foods (A), (A), etc. placed in the water bath (1) are efficiently warmed.

And in the above, the discharge port (13) and the suction port (14) are arranged at a pair of diagonally located corners of the bottom wall (11) of the hot water tank (1), and the distance between them is set. Because of the large size, the water spouted from the discharge port (13) flows so as to surround the whole of the hot water tank (1) and reaches the suction port (14) side, whereby the whole water tank (1) is agitated. The stirring efficiency is improved.
