Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an automatic bread maker that is used in general households and is capable of making bread by rotary kneading wheat flour and the like.

Conventional technology Generally, when making bread, equipment such as a kneading machine, fermentation machine, rolling pin, oven, etc. Making bread required considerable skill. In order to solve these problems, an automatic bread maker has been proposed that has a kneading function, a fermentation function, and an oven function housed in a single product as shown in FIG. 3.

The device shown in FIG. 3 includes a frame 2 provided inside a main body 1, and a motor 3 mounted on this frame 2.
A heating tank 6 equipped with a heater 4 and a heat insulating material 5 on the outside
is fixed, and a kneading container 8 having kneading blades 7 is removably installed in the heating tank 6. Further, at the bottom of the kneading container 8, as shown in FIG. The shaft 9 that transmits the
A sealing material 16 is provided to prevent intrusion into the kneading blade 7, and the kneading blade 7 is driven at a reduced speed by a belt 10 and a pulley 11. In addition, the upper part of the heating tank 6 is connected to the lid body 1.
2, and the temperature sensor 13 is fixed to the outer surface of the heating tank 6. 14 is a timer, a temperature control circuit, and a power control circuit. With this configuration, when ingredients are put into the kneading container 8 and the timer is set, operation starts at a predetermined time, and each step is automatically performed by the timer and temperature adjustment, and the bread is baked at the predetermined time. be.

Problems to be Solved by the Invention If a conventional configuration uses a sealing material 16 as shown in FIG. Due to the pressure of the material at the time, the material may enter the inside of the sealing material 16, and in the worst case, the bearing 15
There was a problem in that the particles penetrated into the parts, causing the shaft 9 and the bearing 15 to become stuck together, or causing seizing.

Additionally, if baking is performed in the same container, the bread will stick to the area around the sealing material 16 (particularly the shaft 9), and if kneading is continued in that state, the movement of the shaft 9 in the thrust direction will cause the baked bread to stick. There was also the problem that a portion of the sealing material 16 entered the interior of the sealing material 16.

The present invention has been made in view of these problems, and by applying a single-stage sealing configuration to the upper end surface of the sealing material, it is possible to improve the reliability against material intrusion into the interior of the sealing material. The purpose is to provide a bread making machine.

Means for Solving the Problems In order to achieve the above object, the present invention includes a kneading container provided in a firing container, a blade shaft rotatably supported on a bearing fixed to the bottom of the kneading container, and a blade shaft rotatably supported on a bearing fixed to the bottom of the kneading container. The kneading blade is attached to the upper end of the blade shaft and provided at the inner bottom of the mixing container, and the sealing material is installed to the bearing and seals the top of the blade shaft. An annular lip is provided that extends outward with respect to the shaft, and the upper end of the annular lip is in close contact with the lower end surface of the kneading blade.

Effect The above configuration increases the sealing effect for the bearing that is press-fitted to the bottom of the kneading container and supports the shaft, making it more reliable against material intrusion. . In addition, the direction of the seal formed on the upper end surface of the seal material is changed by 90 degrees compared to the conventional seal part formed by the shaft and seal material, making it more effective in preventing material intrusion. be.

The upper end of this annular lip 76 is in close contact with the lower end surface of the blade shaft holder 77 of the kneading blade 53 which can be attached to the blade shaft 54. The kneading container 55 is configured so as to come into pressure contact with the temperature detection section 50 when installed in the firing container 44, and has a holder 56 attached to its upper end. Further, the firing container 44 has an upper portion fixed to a fixing member 57, and a main body upper frame 58 further fixed to the fixing member 57. And the main body 30 is

The temperature of the kneading container 55 is adjusted in step 8, and the steps of primary fermentation, degassing, shaping fermentation, and baking are automatically performed to bake the bread at the set time.

Effects of the Invention As is clear from the above embodiments, the sealing material for the automatic bread maker of the present invention is provided with a sealing lip in the direction of the blade axis, and an annular lip that extends outward with respect to the blade axis. is designed to be in close contact with the lower end surface of the kneading blade, and by adopting this configuration, the sealing effect on the bearing is extremely excellent, and as a result, the sealing performance is further improved than the conventional sealing method. I can do it.

Furthermore, since the conventional seal part consists of a seal material and a shaft, the same force is applied to both seal parts even if the lip is double lipped, but in the present invention, the seal material and shaft are Since the direction is changed by 90 degrees with respect to the constructed seal part, even if material were to penetrate through the annular lip, the force entering the conventional seal part would be attenuated by the annular lip and , because the directions are different, the force becomes extremely weak. Furthermore, since the kneading blades can be attached freely, even if they get over the annular lip and get in, they can be cleaned, which greatly increases the reliability of the functional parts, as they are unlikely to get into the bearings. This is something that can be improved.
