[0002] Ice cream and smoothies are a type of cold drink food and are very popular among adults and children in the hot summer. The production of ice cream generally requires the use of a cold drink machine. A cold drink machine, also known as an ice cream freezing machine, is an automated device specially designed for producing frozen desserts - ice cream. According to its use, cold drink machines can be divided into large-scale freezing machines used in factory assembly lines and commercial cold drink machines used in the catering industry.

[0003] Generally, the structure of a general household cold drink machine is simple. There is usually a temperature sensor arranged outside the freezing cylinder. However, since the outside of the freezing cylinder is connected to the heat exchange tube to achieve freezing, the temperature detected by the temperature sensor is different from the temperature of the food materials inside the freezing cylinder. Therefore, users cannot accurately grasp the temperature of the milk slurry, resulting in the ice cream being in a liquid state sometimes when it is made. Summary of the Utility Model

[0004] Aiming at the above defects, the purpose of the utility model is to provide a cold drink machine capable of measuring the temperature of food materials to solve the problem that the temperature sensor cannot directly feedback the temperature of the food materials.

[0011] It is characterized in that it further comprises a temperature sensor. The temperature sensor comprises an induction end and a connection end. The induction end is placed inside the freezing cylinder and is flush with the inner wall surface of the cylinder body of the freezing cylinder;

[0012] The connection end is placed outside the freezing cylinder and is electrically connected to the electric control component.

[0033] As Figures 1 to 3 shown, a cold drink machine capable of measuring the temperature of food ingredients includes:

[0034] An electric control component, a refrigeration component (2), and a stirring component (3) are electrically connected to control the working states of the refrigeration component (2) and the stirring component (3), or display the temperature of the food ingredients in the freezing cylinder.

[0035] A feeding component (7) is communicated with the freezing cylinder (5) for conveying raw materials to the freezing cylinder.

[0036] The refrigeration component (2) is used to refrigerate the freezing cylinder (5).

[0037] The stirring component (3) is used to stir the raw materials inside the freezing cylinder (5) to form finished products and push the finished products to the discharging component (4).

[0038] The discharging component (4) is used to discharge the finished products in the freezing cylinder.

[0039] It further includes a temperature sensor (6). The temperature sensor (6) includes a sensing end (6a) and a connection end (6b). The sensing end (6a) is placed inside the freezing cylinder (5), and the sensing end (6a) is flush with the inner wall surface of the cylinder body of the freezing cylinder (5).

[0040] The connection end (6b) is placed outside the freezing cylinder (5), and the connection end (6b) is electrically connected to the electric control component.

[0041] An electric control component (9) and a feeding port are provided on one end face of the outer shell (1). The feeding port is communicated with the freezing cylinder (5) through the feeding component (7).

[0042] The refrigeration component (2), the stirring component (3), and the freezing cylinder (5) are arranged inside the outer shell (1).

[0043] The refrigeration component (2) is provided with a heat exchange tube (2d), and the heat exchange tube (2d) is wound around the surface of the freezing cylinder (5).

[0044] The stirring assembly (3) is arranged on one side of the housing (1). A stirring paddle (3c) extends from the stirring assembly (3), and the stirring paddle (3c) is placed inside the freezing cylinder (5).

[0045] The discharging assembly (4) is arranged on the other side of the housing (1), and the discharging assembly (4) is connected to one end of the freezing cylinder (5).

[0046] In the present utility model, a user can pour milk slurry through the feeding port. The milk slurry enters the freezing cylinder (5) through the feeding assembly (7). After the refrigeration assembly (2) is started, the freezing cylinder (5) is cooled through the heat exchange tube (2d), so that the temperature of the milk slurry in the freezing cylinder (5) is reduced. During the freezing process of the milk slurry, the milk slurry is stirred by the stirring assembly (3), so that more air can be filled when the milk slurry crystallizes, making the ice cream softer and with a better taste. When the temperature of the milk slurry reaches a certain temperature, the ice cream can be output by pulling the discharging assembly (4).

[0047] In order to better detect the temperature of the milk slurry, a through hole is formed in the freezing cylinder (5), and the temperature sensor (6) is installed on the through hole. The sensing end (6a) of the temperature sensor (6) is placed inside the freezing cylinder (5) and can directly contact the milk slurry, so as to more accurately obtain the temperature of the food material. The electronic control assembly (9) can be a display screen with a control chip, and the connecting end (6b) of the temperature sensor (6) is connected to the electronic control assembly (9) through a wire, and the detected temperature of the food material can be directly fed back to the electronic control assembly (9). The user can judge whether the milk slurry is frozen into ice cream according to the temperature displayed on the electronic control assembly (9). At the same time, the user can touch the display screen to adjust the power of the refrigeration assembly (2) and the stirring assembly (3).

[0048] In addition, a stirring paddle is arranged in the freezing cylinder (5). If the sensing end (6a) of the temperature sensor (6) protrudes from the inner wall surface of the freezing cylinder (5), it may be scratched by the stirring paddle (3c), which may cause damage to the temperature sensor (6). If the sensing end (6a) of the temperature sensor (6) is recessed from the inner wall surface of the freezing cylinder (5), it may cause some food materials to remain at the sensing end (6a), increasing the cleaning difficulty of the cold drink machine. As Figure 3 shown, in the present utility model, one surface of the sensing end (6a) is set to be an arc surface, and the radian of the arc surface fits the radian of the inner wall of the freezing cylinder (5). After the temperature sensor (6) is installed, the sensing end (6a) can be flush with the inner wall surface of the freezing cylinder (5), ensuring that the temperature sensor (6) can contact the food material while not affecting the normal operation of other devices or process flows.

[0049] Preferably, the temperature sensor (6) is arranged at one end close to the discharging component (4).

[0050] Due to the continuous stirring of the stirring paddle, the milk slurry will be pushed forward and thus accumulate at one end of the freezing cylinder (5) close to the discharging component (4). Since the basic purpose of detecting the temperature is to detect whether the milk slurry has reached the temperature to become ice cream. When the discharging component (4) extrudes ice cream, it is the milk slurry at this position that is extruded. As long as the temperature of the milk slurry at this place reaches the crystallization temperature, ice cream can be extruded through the discharging component (4). If the temperature sensor (6) is arranged at one end close to the stirring component (3), when the temperature sensor (6) detects the temperature of the ingredients, the user may add new milk slurry. At this time, even if the milk slurry at the front end has crystallized into ice cream, the temperature detected by the temperature sensor (6) has not reached the crystallization temperature of the milk slurry, thus increasing the waiting time of the user.

[0051] Preferably, at least two temperature sensors (6) are provided, including a first temperature sensor (6c) and a second temperature sensor (6d). The first temperature sensor (6c) is arranged at one end close to the discharging component (4), and the second temperature sensor (6d) is arranged at one end close to the feeding component (7);

[0052] Both the first temperature sensor (6c) and the second temperature sensor (6d) are electrically connected to the refrigeration component (2), and the first temperature sensor (6c) is also electrically connected to the electronic control component (9).

[0053] As Figure 2 shown, in an embodiment of the present invention, multiple temperature sensors (6) are provided. The temperatures of different regions in the freezing cylinder (5) are determined by the multiple temperature sensors (6), so as to better control the operation of the refrigeration component. For example, under normal circumstances, the temperatures detected by the first temperature sensor (6c) and the second temperature sensor (6d) are the same. At this time, the refrigeration component (2) can be controlled to maintain at the crystallization temperature of the milk slurry. When new milk slurry is added, the temperature detected by the second temperature sensor (6d) is lower than the temperature detected by the first temperature sensor. In order to accelerate the crystallization of the milk slurry, the power of the refrigeration component (2) can be increased at this time, so as to accelerate the conversion of ice cream. When the temperatures of the first temperature sensor (6c) and the second temperature sensor (6d) approach each other, the power of the refrigeration component (2) is readjusted.

[0054] Preferably, both the first temperature sensor (6c) and the second temperature sensor (6d) are electrically connected to the stirring component (3).

[0055] When new milk slurry is added, the temperature detected by the second temperature sensor (6d) is lower than the temperature detected by the first temperature sensor (6a). To accelerate the crystallization of the milk slurry, the stirring assembly (3) can increase its power according to the temperature difference between the first temperature sensor (6c) and the second temperature sensor (6d). Under the action of inertia, part of the milk slurry is thrown onto the inner wall of the freezing cylinder (5), increasing the contact area between the milk slurry and the inner wall of the freezing cylinder (5), thereby increasing the heat exchange efficiency of the milk slurry and ultimately accelerating the conversion of ice cream.

[0056] Preferably, taking the central axis of the freezing cylinder (5) as the reference line, the horizontal height of the second temperature sensor (6d) is not higher than the horizontal height of the reference line.

[0057] Since the main function of the second temperature sensor (6d) is to detect the temperature of the newly added milk slurry, if the position of the second temperature sensor (6d) is set too high. If the amount of newly added milk slurry by the user is small, then the second temperature sensor (6d) cannot contact the newly added milk slurry at this time, and thus no new temperature feedback can be obtained.

[0058] Preferably, the stirring assembly (3) includes a power output member (3a), a transmission rod (3b), and the stirring paddle (3c). The power output member (3a) is arranged on one side of the housing (1). One end of the transmission rod (3b) is arranged in the freezing cylinder (5) through a bearing. The other end of the transmission rod (3b) is connected to the power output member (3a). The plurality of stirring paddles are equidistantly distributed on the surface of the transmission rod (3b). The transmission rod (3b) is located at the position of the central axis of the freezing cylinder (5).

[0059] In an embodiment of the present invention, the power output member (3a) is a motor. The motor drives the transmission rod (3b) and the stirring paddle (3c) to rotate. During the rotation, the stirring paddle (3c) drives the milk slurry to rotate, so that part of the milk slurry contacts the inside of the freezing cylinder (5), accelerating the conversion of ice cream. At the same time, during the conversion process, due to stirring, air is introduced into the milk slurry, making the ice cream more fluffy and the taste better.

[0060] Preferably, the refrigeration assembly (2) includes a condenser (2a), an evaporation pan (2b), a compressor (2c), and a heat exchange tube (2d);

[0061] One end of the heat exchange tube (2d) is connected to the inlet of the compressor (2c). The outlet of the compressor (2c) is connected to the inlet of the condenser (2a). The outlet of the condenser (2a) is connected to the inlet of the evaporation pan (2b). The outlet of the evaporation pan (2b) is connected to the other end of the heat exchange tube (2d).

[0062] A tube-in-tube evaporator is provided inside the evaporation pan (2b). When it is necessary to cool the freezing cylinder (5), the compressor (2c) sucks in the low-temperature and low-pressure refrigerant gas in the heat exchange tube (2d), compresses it to increase its temperature and pressure, and sends it into the condenser (2a). The condenser (2a) cools the high-temperature and high-pressure refrigerant gas and converts it into a high-pressure liquid. Then, the high-temperature liquid is input into the tube-in-tube evaporator to evaporate the low-temperature and low-pressure liquid refrigerant into a refrigerant gas, which is then re-introduced into the heat exchange tube (2d). The heat exchange tube (2d) is wound around the outer wall of the freezing cylinder (5) to cool the freezing cylinder (5) through heat exchange.

[0063] Preferably, it further includes a carrier plate (8), and the carrier plate (8) is located below the discharging assembly (4).

[0064] The setting of the carrier plate (8) not only facilitates the user to place a container for receiving the finished ice cream, but also prevents the finished ice cream from dripping onto the table.

[0065] In the description of this specification, the description of reference terms such as "one embodiment", "some embodiments", "schematic embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0066] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the claims and their equivalents.
