Description

Home Yogurt Maker {HOME YOGURT MAKING MACHINE BY DIRECTLY INCUBATING MILK BOTTLE THEREIN}

When making yogurt at home, conventional yogurt makers can be provided to make yogurt. However, it has the following drawbacks.

1. Bowls or containers of yogurt makers that cause inconvenience to users should be cleaned and disinfected.

2. Bottles of milk purchased in supermarkets cannot be cultured directly in yogurt makers, and bottles in yogurt maker bowls must be opened to pour milk, when yogurt is still made by adding bacteria to the milk to produce yogurt. Inconvenient procedures will follow.

3. Conventional heating coils may have overheating or heterogeneous heating phenomena, thereby degrading the taste or quality of the yogurt released.

The inventors have devised a home yogurt maker which finds the drawbacks of the conventional home yogurt maker and directly cultures the milk bottle in the yogurt maker.

An object of the present invention is to provide a heating device having a housing, an internal incubator thermally insulated and mounted to the housing, and a PTC semiconductor heating element mounted to the bottom of the internal incubator to slowly warm the incubator to make yogurt at home convenient. Including an apparatus, the inner incubator provides a home yogurt maker having an inner chamber for storing the milk bottle or soy milk bottle directly in the inner incubator.

As shown in the figure, the home yogurt maker of the present invention is an internal incubator fixed to the housing 1 for storing, inserting, or inserting a milk bottle 4 filled with milk in the housing 1, the incubator 2. 2) a heating means 3 formed in the housing 1 and arranged in the incubator 2 for heating and warming the milk bottle 4 while stored in the incubator 2. The design forms of the elements of the present invention are not limited.

The housing 1 forms an interior 10 and has an outer wall 11 having an upper opening 111 on an upper edge, a lower cover 12 fixed below the outer wall 11, and the exterior. And an upper cover portion 13 covering the upper opening 111 of the wall 11.

The inner incubator 2 has an inner wall (or incubator wall) 21 that forms an inner chamber 20 therein for storing, inserting, or placing a milk bottle (or soy milk bottle), and a lower opening of the inner wall 21. A bottom plate 22 fixed on the bottom of the inner wall 2, an upper opening of the inner wall 21, and an upper rim fixed on the upper edge of the outer wall 11 of the housing 1 for sealing; 211, and “empty” between the bottom plate 22 and the bottom 41 of the milk bottle 4 when the milk bottle is stored in the chamber 20 of the incubator 2 as shown in FIG. Or air) space ”20a, including a plurality of protrusions 221 formed on the bottom plate 22.

The protrusion 221 formed on the lower plate 22 fixes the heating means 3 on the lower plate 22 of the incubator 2 by inserting the screw S through the screw socket 222 or the incubator 2. ) May also be performed as the screw socket 222 when securing the bottom cover 12.

The inner incubator 2 has a plurality of ribs 23 formed on the wall 21, and heating means for the wall 21 of the incubator 2 to heat or warm the incubator 2 and the milk bottle 4. A recess 231 for arranging (or contacting) the thermally conductive member 32 of (3) is formed in the lower portion of each rib 23.

The heating means 3 comprises a positive-temperature-coefficient (PTC) semiconductor heating element 31 embedded on a carrier plate 311, a thermally conductive member fixed to the bottom plate 22 of the inner incubator 2. And an elastic back plate 33 which cooperates with the thermally conductive member 32 to sandwich the PTC semiconductor heating element 31 between the thermally conductive member 32, the thermally conductive member 32. And the elastic back plate 33 are fixed to the bottom plate 22 of the inner incubator 2.

The thermally conductive member 32 has a lower plate 321 fixed to the lower portion of the inner incubator 2 and a plurality (or two) disposed upwardly from the lower plate 321 and disposed on the wall 21 of the incubator 2. A side wall plate 322, the side wall plate 322 formed on the wall 21 of the incubator 2 to closely surround the side wall plate 322 with respect to the wall 21 of the incubator 2. An upper end 322a of each side wall plate 322 that engages with the recess 231 of the rib 23, and the lower plate 321, the PTC semiconductor heating element 31 and the elastic rear plate 33 are incubators. It is fixed to the lower part of (2) with the screw (S).

The PTC semiconductor heating element 31 is sandwiched between the bottom plate of the thermally conductive member and the elastic back plate; The thermally conductive plate is made of an electrically conductive material and electrically connected to the first polarity (anode) of the power source, and the elastic back plate is made of an electrically conductive material and electrically connected to the second polarity (cathode) of the power source, and heated Electricity is supplied to the thermally conductive member 32 and the resilient back plate 33 to operate the device to generate heat, which thermally heats the milk in the milk bottle 4 to which bacteria have been added to make yogurt directly from the milk bottle. Heat will be transferred through the thermally conductive plate 32 (including the bottom plate 321 and the sidewall plate 322) to warm or heat the incubator 2 to incubate or condense.

The heating means 3 further comprise a thermostat or temperature controller 30 electrically connected to the PTC semiconductor heating element 31 for adjusting the incubation temperature in order to make the yogurt smooth and optimal.

1. The milk bottle (4) purchased from the supermarket can be put directly into the incubator to produce yogurt without pouring into the yogurt maker for cultivation and is discharged from the incubator at the end of the cultivation, thereby making the yogurt convenient at home. Make it.

2. The PTC semiconductor heating element 31 is provided to obtain a stable optimum incubation temperature without overheating the yoghurt mixture and without degrading the yoghurt quality.

3. The lower plate 22 of the incubator is provided with a plurality of protrusions 221 to prevent the heating element 31 fixed in the lower part of the incubator 2 from coming into close contact with the bottle in order to prevent overheating of the milk adjacent to the incubator. have. On the other hand, the side wall plate 322 of the thermally conductive member 32 can transfer heat well from the lower plate 321 and the wall 21 of the incubator 21 to homogeneously heat or warm the milk bottle 4 in a three-dimensional form. Transfer heat in the form of a column. So, the taste and quality of the yogurt so formed becomes even better.

4. The elements of the yogurt maker of the present invention can be easily assembled for operation or easily removed for maintenance. The assembly of the device is simple and the product cost is low.

The present invention can be modified without departing from the spirit and technical spirit of the present invention.

As described above, according to the home yogurt maker of the present invention, the milk bottle or soymilk bottle containing milk can be directly put into the chamber of the incubator, and the optimum incubation temperature is stable without overheating the yoghurt mixture and reducing the quality of the yoghurt. Can be obtained.
