Description

An energy-saving coffee pot

technical field

The utility model belongs to the technical field of small household appliances, in particular to an energy-saving coffee pot.

Background technique

In the coffee pots of the prior art, there is no heat insulation device outside the heating element for heating water. Therefore, only a part of the heat emitted from the heating element directly acts on the water channel and heats the water. The other part is emitted from both sides of the heating element, so its heating efficiency is low.

In addition, in existing coffee pots, the heating element generally used for boiling water has only one water channel. Because the contact surface between the water channel and the heating tube is relatively small, only a small part of the heat emitted from the heating tube directly acts on the water channel. and heat the water. And the other part does not directly act on the water channel but emits from both sides of the heat pipe. Equally, its heating efficiency is low.

Have again, the heat preservation device of existing coffee pot, it is to control the switch of heating tube by the opening and closing of mechanical temperature controller, consumes a lot of energy like this. In addition, some coffee pots are not equipped with a dry-boiling device, so that when the water tank is less water or no water, the heating pipe will continue to work, consuming energy, and there is a hidden danger of failure.

Detailed ways

The utility model is described in detail below in conjunction with accompanying drawing:

Embodiment one:

This embodiment discloses an energy-saving coffee pot, as shown in Figures 1, 2, and 3, which includes a pot body 1, and the inner cavity of the pot body 1 includes: a coffee making component 2, a water tank 4, and a heating element in sequence from top to bottom 5. A coffee cup 8 is provided on the pot body 1 and below the coffee making assembly 2, and the heating element 5 includes a water channel and a heating tube fused with the outer wall of the water channel; wherein, the energy-saving coffee pot It also includes a thermal insulation cover 3 that is positioned outside the heating element and plays a role of thermal insulation.

The thermal insulation cover 3 is made of high temperature resistant material, which can reduce the energy loss when the heat pipe is working, reduce the time for the coffee maker to make coffee, and save energy.

Preferably, the thermal insulation cover 3 is made of resin and glass fiber high temperature resistant material.

The thermal insulation cover 3 adopts a cover-like structure and covers the sides and bottom of the heating element 5 .

Due to gravity, the water in the water tank 4 flows into the heating element 5 to directly heat the water. A one-way valve is placed in the water path between the water tank 4 and the heating element 5, and the heated water can enter the coffee assembly. 2. Brew coffee, and the coffee liquid drips into the coffee cup 8 again.

As shown in Figures 2, 4, and 5, the heating element 5 is arc-shaped, and the heating element 5 includes two independent water passages 51 and a heating pipe 52 that is fused with the outer wall of the water passage 51. The water channels 51 are connected in series.

The two independent water passages 51 are respectively located on the outer side and the bottom side of the heating pipe 52 .

Due to the adoption of two water passages 51 and one heating pipe 52, the contact area between the water passage 51 and the heating pipe 52 is increased, so that a large part of the heat emitted by the heating pipe 52 is absorbed by the water in the two water passages 51, and only a few Partially dissipated, the heat absorption rate is high, and it has the effect of high efficiency and energy saving. Certainly, the water channel of the heating element 5 can also adopt three channels, so the efficiency will be better, but the cost will be slightly higher.

The energy-saving coffee pot also includes a PTC heating element 6 capable of maintaining the temperature of the coffee in the coffee cup 8 , and the PTC heating element 6 is located below the bottom of the coffee cup 8 .

The PTC heating element 6 is located at the bottom of the inner cavity of the kettle body 1 .

Generally the liquid in the coffee cup 8 is coffee. The PTC thermal insulation element 6 is placed directly below the bottom of the coffee cup 8, so that the heat emitted by the PTC thermal insulation element 6 is transferred to the bottom of the coffee cup 8 for absorption, and the coffee in the coffee cup 8 is kept at a certain temperature. Since the coffee that has not been poured from the coffee cup 8 will be left for a period of time after the coffee is finished, the temperature of the coffee in the coffee cup 8 will decrease. Adopting PTC thermal insulation element 6 then can make the temperature of the coffee in the coffee cup 8 inside can keep certain temperature. In the utility model, the PTC thermal insulation element 6 is used to replace the opening and closing of the traditional temperature controller to control the on-off operation of the heating pipe, which is more energy-saving. Generally speaking, the PTC thermal insulation element can save energy by more than 20%.

As shown in Figures 1, 2, 4, and 6, the bottom of the water tank 4 is provided with a water level switch assembly 7 that is electrically connected to the power supply of the heating element 5 and controls automatic shutdown when the water level of the water tank is lower than the minimum limit value.

The water level switch assembly 7 includes a sensor switch 72 and a float 71 floating up and down along a limit rod 73 at the bottom of the water tank.

When the water in the water tank was more, the float 71 floated on the top, and the water level switch was closed, and now the heating element 5 can be powered to heat the water. When the water level in the water tank was relatively low, the float would sink thereupon, and the water level switch would be disconnected, so that it could not supply power to the heating element 5, which would also save energy.

Compared with the prior art, the utility model has the following advantages: firstly, the thermal insulation cover makes it difficult for the heat generated by the heating element to dissipate to the outside, and most of it is absorbed by the water in the water channel, thereby producing the effect of thermal insulation. Its two, because the heating element of the present utility model adopts two water passages and a heating pipe, a large part of the heat that the heating pipe sends is absorbed by the water in the two water passages, only a small part is emitted, and the heat absorption rate is high , so it has the effect of high efficiency and energy saving. Third, due to the use of PTC heat preservation elements for heat preservation, it has been proved by experiments that more than 20% of energy can be saved after the former two are used together. Fourth, there is a water level switch assembly at the bottom of the water tank, which can prevent dry burning, and at the same time, prevent the remaining water at the bottom of the water tank from completely turning into steam and cause unnecessary energy consumption, so it can also save energy .

Embodiment two:

As shown in FIG. 7 , this embodiment discloses another energy-saving coffee pot with a structural form, including a pot body 1 , and the pot body 1 sequentially includes: a coffee making component 2 , a water tank 4 and a heating element from top to bottom. 5. A coffee cup 8 is provided under the coffee making assembly 2, and the heating element 5 includes a water channel and a heating tube fused with the outer wall of the water channel; wherein, the energy-saving coffee pot also includes a The thermal insulation cover 3 that plays thermal insulation effect.

The coffee making assembly 2 includes an upper cover 21, a shower assembly 22 and a brewing basket assembly 23. The brewing basket assembly 23 is used to hold coffee powder or coffee pods or coffee cakes, and the shower assembly 22 is used to spray hot water for brewing coffee. The upper cover 21 is used to seal the upper part of the brewing basket assembly 23 .

The lower part of the kettle body 1 is a base 11 on which the coffee cup 8 is placed, and the bottom of the base 11 is a bottom cover 12 .

The specific implementation methods listed above are non-restrictive. For those skilled in the art, various improvements and changes made within the scope of the present utility model all belong to the protection scope of the present utility model. For example, the size and shape of the thermal insulation cover change.
