Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, and more specifically, to a thyristor water-cooling component and a coffee machine. Background Art

[0002] With the continuous increase in people's demand for coffee, coffee machines have also been widely used. The thyristor is an important component for controlling the temperature of the heating pot of the coffee machine. It generates a large amount of heat during operation and needs to be cooled. However, currently, the thyristors of coffee machines on the market usually use heat sinks for heat dissipation. However, the heat sink has a large volume and high cost. A coffee machine with double pumps and double boilers requires two circuit boards to control different heating pots, so two heat sinks need to be installed, further increasing the cost.

[0003] In order to reduce costs, Chinese Patent No. CN114040667A discloses a thyristor heat dissipation device and a hot water dispenser, including a main control board; a thyristor integrated on the main control board; a water-cooling seat with a first groove formed by a downward depression on the surface, and an inlet hole and an outlet hole communicating with the first groove are provided on the water-cooling seat; and a heat sink covering the surface of the water-cooling seat to form a water-cooling channel with the first groove. The inlet of the water-cooling channel is the inlet hole, and the outlet of the water-cooling channel is the outlet hole. The thyristor is thermally connected to the heat sink. Although this prior art uses a water-cooling heat dissipation structure and can dissipate heat from the thyristor through cold water to reduce product costs, in this thyristor heat dissipation device, the heat sink is L-shaped, and the thyristor is arranged on the side plate of the heat sink and does not directly contact the bottom plate of the heat sink covering the surface of the water-cooling seat, resulting in poor heat dissipation effect, and it can only dissipate heat for one thyristor and cannot meet the heat dissipation requirements of the double-pump and double-boiler models. Summary of the Utility Model

[0004] In order to overcome the above-mentioned disadvantages of the prior art, the utility model provides a thyristor water-cooling component and a coffee machine, which have the advantages of small volume, good heat dissipation performance and low cost.

[0005] The technical solution adopted by the utility model to solve its technical problems is as follows: A thyristor water-cooling component includes: a water-cooling main body bracket, an open cooling cavity is provided in the upper part of the water-cooling main body bracket, and two water inlets communicating with the cooling cavity are provided in the lower part; a heat conducting sheet fixedly attached to the upper surface of the water-cooling main body bracket, and the heat conducting sheet is used for detachably installing at least one thyristor, and the thyristor is pressed and fixed on the upper surface of the heat conducting sheet; the thyristor is electrically connected to the circuit board, and the water-cooling main body bracket is installed on the circuit board.

[0006] A thyristor water-cooling component provided in this technical solution can dissipate heat from a single or multiple thyristors through a water-cooling structure, and has the advantages of small volume, good heat dissipation performance and low cost; among them, the thyristor is tightly fixed on the upper surface of the heat-conducting sheet, and the heat dissipation effect is better; at the same time, the thyristor water-cooling component can be directly installed on the circuit board to improve the space utilization rate.

[0007] In order to obtain a better cooling effect, the installation position of the thyristor should be above the cooling cavity, but it is not suitable to drill holes for fixation above the cooling cavity, which may cause coolant leakage.

[0008] In a preferred technical solution, the above-mentioned thyristor water-cooling component further includes a gland provided above the thyristor, and the mounting hole of the gland is located outside the area above the cooling cavity; the gland is fixedly connected to the heat-conducting sheet and the water-cooling main body bracket in sequence through the mounting hole to tightly fix the thyristor on the upper surface of the heat-conducting sheet, and the close contact position between the thyristor and the heat-conducting sheet is located within the area above the cooling cavity. In this technology, a gland with a mounting hole outside the cooling cavity range is adopted, and the gland is used to fix and press the thyristor on the heat-conducting sheet, which can not only facilitate the installation and fixation of the thyristor, but also fix the thyristor in a position with good cooling effect.

In this technology, the thyristor water-cooling component and the thyristor are independently separated from the main circuit board and assembled on the sub-circuit board. This structure can meet the situation of insufficient assembly space size of the circuit board, and at the same time the thyristor water-cooling component is more convenient for disassembly and assembly.

[0012] In a preferred technical solution, a groove is provided around the cooling cavity on the water-cooled main body bracket, and a sealing ring is embedded in the groove. The sealing ring is in sealing cooperation with the heat conducting sheet. This sealing ring can prevent water from flowing out of the gap between the water-cooled main body bracket and the heat conducting sheet, playing a sealing role.

[0014] In a preferred technical solution, the heat conducting sheet is made of aluminum material with good heat conduction performance.

[0016] The coffee machine in this technology has only one heating pot, so only one thyristor is needed for control, and a single thyristor is arranged on the thyristor water-cooling component. The thyristor water-cooling component is connected to the water path of the coffee machine, and water is pumped through the thyristor water-cooling component by the first water pump for heat dissipation.

Without adding additional components, compared with the double circuit board structure of the traditional coffee machine with double water pumps and double boilers, it can effectively save costs and improve the space utilization rate of the product.

[0019] From the above technical solutions, compared with the prior art, the beneficial effects of the present invention are as follows: A thyristor water-cooling component provided by the present invention can dissipate heat from a single or multiple thyristors through a water-cooling structure, and has the advantages of small volume, good heat dissipation performance and low cost; among them, the thyristor is tightly pressed and fixed on the upper surface of the heat conducting sheet, and the heat dissipation effect is better; at the same time, the thyristor water-cooling component can be directly installed on the circuit board to improve the space utilization rate; a coffee machine adopting the above thyristor water-cooling component can reduce costs and reduce the volume.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

In addition, in the description of the present utility model, unless otherwise specified, the meaning of "a plurality of" is two or more.

[0033] Refer to Figure 1-8 Describe a thyristor water cooling assembly 100 and a coffee machine according to an embodiment of the present utility model. The thyristor water cooling assembly 100 can be applied to the coffee machine, which helps to reduce the volume of the coffee machine.

[0034] In one embodiment, as Figure 1-4 shown, a thyristor water cooling assembly 100 includes: a water cooling main body bracket 1. An open cooling cavity 11 is provided in the upper part of the water cooling main body bracket 1, and two water inlets 12 communicating with the cooling cavity 11 are provided in the lower part. Among them, the water cooling main body bracket 1 is the main body of the entire thyristor water cooling assembly 100. The two water inlets 12 communicate with the cooling cavity 11, forming two water flow channels inside the water cooling main body bracket 1. Cold water can flow into and out of the cooling cavity 11 through the two water flow channels, and the thyristor is cooled by water cooling.

[0035] A heat conducting sheet 2 is fixedly attached to the upper surface of the water cooling main body bracket 1. The heat conducting sheet 2 is used for detachably mounting at least one thyristor. The thyristor is pressed and fixed on the upper surface of the heat conducting sheet 2. Among them, the thyristor is fixed on the heat conducting sheet 2 by pressing, and the thyristor is in close contact with the heat conducting sheet 2, having a better heat dissipation effect.

[0036] The thyristor is electrically connected to the circuit board 6, and the water cooling main body bracket 1 is installed on the circuit board 6.

[0037] In this embodiment, neither of the two water inlets 12 is strictly defined as the water inlet end or the water outlet end. One of the two water inlets 12 can be used as the water inlet end, and the other as the water outlet end, so as to adaptively install the thyristor water cooling component 100 according to the actual situation, thereby improving the flexibility of installation.

[0038] During specific implementation, the thyristor is closely attached to the heat conducting sheet 2. The thyristor in operation directly transfers heat to the heat conducting sheet 2. Cold water flows in from one water inlet 12, enters the cooling cavity 11, contacts the heat conducting sheet 2, absorbs heat, and then flows out from the other water inlet 12, thereby realizing the heat dissipation of the thyristor. At the same time, one or more thyristors can be installed according to actual needs. The lower surface of the heat conducting sheet 2 contacts the water in the cooling cavity 11, and the upper surface of the heat conducting sheet 2 contacts the lower surface of the thyristor, for conducting the heat of the thyristor into the flowing water in the cooling cavity 11. The water cooling main body bracket 1 can be installed on the circuit board 6 through a screw structure, improving the space utilization rate.

[0039] In one embodiment, as Figure 1-2 shown, the thyristor water cooling component 100 further includes a gland 3 provided above the thyristor. The mounting hole of the gland 3 is located outside the area above the cooling cavity 11; the gland 3 is fixedly connected to the heat conducting sheet 2 and the water cooling main body bracket 1 in sequence through the mounting hole, so as to press and fix the thyristor on the upper surface of the heat conducting sheet 2. The close contact position between the thyristor and the heat conducting sheet 2 is located within the area above the cooling cavity 11.

[0040] Among them, the gland 3 is provided with a mounting hole for a screw to pass through, the water cooling main body bracket 1 is provided with a screw seat 15 corresponding to the position of the mounting hole, and the heat conducting sheet 2 is provided with a through hole or a through groove for a screw to pass through; the screw passes down through the heat conducting sheet 2 from the mounting hole on the gland 3 and enters the screw seat 15, assembling the gland 3, the heat conducting sheet 2 and the water cooling main body bracket 1 into one body, and at the same time pressing and fixing the thyristor on the upper surface of the heat conducting sheet 2 within the area above the cooling cavity 11, which can obtain a better cooling effect.

[0041] In the actual application scenario, the position above the cooling cavity 11 has a better cooling effect, that is, the installation position of the thyristor is preferably above the cooling cavity 11. However, it is not suitable to drill holes for fixing at the position above the cooling cavity 11, which may cause coolant leakage. Therefore, in this embodiment, a gland 3 with a mounting hole located outside the range of the cooling cavity 11 is adopted to press the thyristor, without drilling holes above the cooling cavity 11, which is convenient for installing and fixing the thyristor and also fixes the thyristor at a position with good cooling effect.

[0042] During specific implementation, mounting holes can be respectively provided on both sides and the middle of the front end of the gland 3. The mounting holes on both sides are symmetrically positioned. The part of the gland 3 between the mounting holes on both sides and the mounting hole in the middle of the front end is used to press down the thyristor tightly, so that the thyristor is tightly pressed and fixed on the upper surface of the heat conducting sheet 2 in the area above the cooling cavity 11. At this time, there are at least two mounting positions for the thyristor. During specific implementation, according to actual needs, two thyristors can be installed, or only one thyristor can be installed. The gland 3 plays a role in fixing and pressing the thyristor tightly.

[0043] In another embodiment, as Figure 3-4 shown, the heat conducting sheet 2 is provided with screw posts 22, and the thyristor is provided with threaded holes; the thyristor is installed on the screw posts 22 through the threaded holes. During specific implementation, nuts 4 and flat washers 5 can be used to install the thyristor on the screw posts 22 through the threaded holes. This embodiment can also conveniently fix the thyristor and has a good cooling effect, but screw posts 22 need to be provided on the heat conducting sheet 2, with high process and cost.

[0044] Based on the above embodiments, after the thyristor water cooling assembly 100 is assembled, it can be cooperatively installed on the circuit board 6 of the coffee machine.

[0045] In one embodiment, as Figure 5 shown, positioning posts 14 are respectively provided at both ends of the side surface of the water cooling main body bracket 1, and a fixing screw post 13 is provided in the middle of the side surface; the water cooling main body bracket 1 is installed on the circuit board 6 through the positioning posts 14 and the fixing screw post 13, and the pins of the thyristor are electrically connected to the circuit board 6.

[0046] Among them, a plurality of through holes are provided on the circuit board 6. When installing the thyristor water cooling assembly 100, the positioning posts 14 play a positioning role, and the fixing screw post 13 is used to install the thyristor water cooling assembly 100 on the circuit board 6 through screws; the pins of the thyristor can pass through the through holes on the circuit board 6, and the thyristor pins are welded and connected to the electronic board circuit through soldering.

[0047] During specific implementation, 3 circular through holes are provided on the circuit board 6. Two of the through holes cooperate with the positioning posts 14 of the water cooling main body bracket 1, and the other one cooperates with the fixing screw post 13. A screw can be driven from the back of the circuit board 6 to fix the thyristor water cooling assembly 100 on the circuit board 6.

[0048] In the above embodiments, the circuit board 6 can be an integrated circuit board 6, and the thyristor water cooling assembly 100 and the thyristor are both installed on the circuit board 6. At the same time, the thyristor water cooling assembly 100 can be directly installed on the circuit board 6 to improve space utilization rate.

[0049] Furthermore, the circuit board 6 can be split into a main circuit board 61 and a sub - circuit board 62 according to needs.

[0050] In one embodiment, as Figure 6 shown, the circuit board 6 includes a main circuit board 61 and a secondary circuit board 62; the water-cooled main body bracket 1 is mounted on the secondary circuit board 62 through positioning posts 14 and fixing screw posts 13, the pins of the thyristor are electrically connected to the secondary circuit board 62, and the secondary circuit board 62 is electrically connected to the main circuit board 61 through a lead 63.

[0051] In this embodiment, the thyristor water-cooling assembly 100 and the thyristor are assembled on the secondary circuit board 62. It can meet the situation of insufficient assembly space size of the circuit board 6, and at the same time, the thyristor water-cooling assembly 100 is more convenient for disassembly and assembly.

[0052] In one embodiment, a groove is provided around the cooling cavity 11 on the water-cooled main body bracket 1, and a sealing ring 16 is embedded in the groove. The sealing ring 16 is in sealing cooperation with the heat-conducting sheet 2 to prevent water from flowing out of the gap between the water-cooled main body bracket 1 and the heat-conducting sheet 2.

[0053] In one embodiment, the heat-conducting sheet 2 is provided with a grounding screw hole 21 for installing a grounding screw to prevent electric leakage.

[0054] In one embodiment, the heat-conducting sheet 2 is made of aluminum material. Specifically, in implementation, the heat-conducting sheet 2 can also be made of other materials with good heat-conducting performance.

[0055] Based on the above embodiments, it can be seen that the thyristor water-cooling assembly 100 is small in volume, and two circuit boards 6 can also be combined into one body, so that two thyristors share a water-cooling structure for heat dissipation, which can reduce the cost of the circuit board 6 of the coffee machine, and at the same time reduce the occupied space of the circuit board 6, which is beneficial to realizing more functions of the circuit board 6 with the same area.

[0056] Since the thyristor water-cooling assembly 100 can meet the thyristor heat dissipation requirements of coffee machine models with single pump and single boiler or double pumps and double boilers, the above circuit board 6 can achieve the function of controlling single pump and single boiler or double pumps and double boilers simultaneously without changing the hardware, only by changing the software.

[0057] In one embodiment, as Figure 7-8 shown, the present utility model provides a coffee machine, which can be designed into a single pump and single boiler model or a double pump and double boiler model according to needs. The water path structures of different models are as Figure 7 and Figure 8 shown. Because the volume of the above thyristor water-cooling assembly 100 is small enough, all functions can be concentratedly designed in the main circuit board 61 of the coffee machine. At this time, the main circuit board 61 only needs to be equipped with one or two thyristors according to needs, without adding other circuit boards 6.

[0058] In this embodiment, as Figure 7As shown, the coffee machine includes a water tank 200, a first water pump 301, a first heating pot 401, and a thyristor water cooling component 100 as described in any of the above embodiments; the water outlet end of the first water pump 301 is connected to the first heating pot 401, and the first heating pot 401 is configured with a first thyristor 101, and the first thyristor 101 is arranged on the thyristor water cooling component 100; one water inlet 12 of the thyristor water cooling component 100 is connected to the water tank 200, and the other water inlet 12 is connected to the water inlet end of the first water pump 301.

[0059] The above coffee machine is a single water pump and single boiler model with only one heating pot, so only one thyristor is needed for control, and a single thyristor is arranged on the thyristor water cooling component 100. The thyristor water cooling component 100 is connected to the water path of the coffee machine, and the first water pump 301 pumps water through the thyristor water cooling component 100 for heat dissipation.

[0060] In another embodiment, as Figure 8 shown, the coffee machine further includes a second water pump 302 and a second heating pot 402. The water outlet end of the second water pump 302 is connected to the second heating pot 402, and the second heating pot 402 is configured with a second thyristor 102, and the second thyristor 102 is arranged on the thyristor water cooling component 100; one water inlet 12 of the thyristor water cooling component 100 is connected to the water tank 200, and the other water inlet 12 is respectively connected to the water inlet ends of the first water pump 301 and the second water pump 302.

[0061] The above coffee machine is a double water pump and double boiler model with two heating pots, so two thyristors are needed for control, and two thyristors are arranged on the thyristor water cooling component 100. Compared with the previous embodiment, no additional external components need to be added, only the number of thyristors arranged on the thyristor water cooling component 100 needs to be increased. Compared with the double circuit board 6 structure of the traditional coffee machine double water pump and double boiler model, the coffee machine in this embodiment can effectively save costs and improve the space utilization rate of the product.

[0062] The other components and operations of the thyristor water cooling component 100 and the coffee machine according to the embodiments of the present invention are known to those of ordinary skill in the art and will not be described in detail herein.
