[0040] In related technologies, traditional refrigeration equipment typically installs the evaporator and refrigeration components on one side of the refrigerator compartment to cool it. However, the evaporator can only cool one side of the refrigerator compartment, resulting in uneven temperature distribution within the compartment. Understandably, the temperature in the area closer to the evaporator will be lower, while the temperature in the area farther away will be higher. This temperature difference severely affects the overall cooling uniformity of the refrigerator compartment, thus reducing its cooling effect.

[0041] Therefore, some embodiments of this utility model propose a refrigerated trolley 1000, as detailed below. Figures 1 to 7 The refrigerated trolley 1000 is described below.

[0042] Reference Figure 1 , Figure 2 and Figure 3 As shown in the embodiment of this utility model, the refrigerated trolley 1000 includes a body 100, a refrigeration component 300, and an evaporation component 400. The interior of the body 100 is provided with an insulation shell 200, which divides the interior of the body 100 into an installation cavity 110 and a refrigeration cavity 120. Specifically, the insulation shell 200 is installed inside the body 100, and the inner cavity of the insulation shell 200 is the refrigeration cavity 120. The installation cavity 110 is located outside the shell of the insulation shell 200 and is located at the bottom of the body 100. In this embodiment, the refrigeration component 300 is installed in the mounting cavity 110. It is understood that the refrigeration component 300 includes components such as a compressor, a condenser, and a throttling device. The refrigeration component 300 is installed independently in the mounting cavity 110 and is spaced apart from the insulation shell 200, thereby reducing the possibility of heat emitted by the refrigeration component 300 flowing into the insulation shell 200 during operation, reducing the impact of the refrigeration component 300 on the insulation shell 200, and thus improving the insulation effect of the insulation shell 200.

[0043] Reference Figure 2 and Figure 3 As shown, in this embodiment of the invention, the evaporation assembly 400 is connected to the refrigeration assembly 300 to form a refrigerant circulation loop for circulating refrigerant. Specifically, the evaporation assembly 400 is arranged around the outer wall of the insulation shell 200. In this embodiment, the evaporation assembly 400 includes two first evaporators 410, which are connected one-to-one to two opposite sidewalls of the insulation shell 200. The refrigerant circulation loop is used to cool the refrigeration chamber 120. Specifically, the two first evaporators 410 are installed on two opposite outer wall surfaces of the insulation shell 200 and cover the outer wall surfaces. The two first evaporators 410 are connected to the refrigeration assembly 300 to form a refrigerant circulation loop, thereby achieving cooling of the refrigeration chamber 120. In this embodiment, the first evaporators 410 and the insulation shell 200 can be connected by adhesive or by fasteners or other means; this embodiment does not limit this.

[0044] It is understood that the evaporator assembly 400 is disposed on at least two sides of the refrigeration chamber 120. Based on this, the evaporator assembly 400 can cool at least two sides of the refrigeration chamber 120, thereby improving the uniformity of the overall cooling of the refrigeration chamber 120 by the evaporator assembly 400, thus improving the uniformity of the temperature distribution in the refrigeration chamber 120, thereby improving the cooling effect of the refrigeration chamber 120, and further improving the reliability of the refrigerated trolley 1000.

[0045] Reference Figure 3 , Figure 4 and Figure 5 As shown, in this embodiment of the present invention, the evaporation assembly 400 further includes a second evaporator 420. The second evaporator 420 is provided on the top wall and / or bottom wall of the insulation shell 200, and the second evaporator 420 is fixedly connected to the insulation shell 200. In one example, the second evaporator 420 is installed on the top wall of the insulation shell 200; in another example, the second evaporator 420 is installed on both the top and bottom walls of the insulation shell 200. In this embodiment, the second evaporator 420 and the insulation shell 200 can be connected by adhesive, fasteners, or other means, and this embodiment does not limit this connection.

[0046] Understandably, the second evaporator 420 is evenly distributed on the top wall and / or bottom wall of the insulation shell 200 and connected to the first evaporator 410. The evaporation assembly 400 can cool three or four sides of the refrigeration cavity 120, which improves the uniformity of the overall cooling of the refrigeration cavity 120 by the evaporation assembly 400, thereby improving the uniformity of the temperature distribution in the refrigeration cavity 120, and further improving the cooling effect of the refrigeration cavity 120, and further improving the reliability of the refrigerated trolley 1000.

[0047] Reference Figure 3 , Figure 4 and Figure 5 As shown, in this embodiment of the invention, the first evaporator 410 and the second evaporator 420 are configured as refrigerant pipes, which are bent and extended and fitted to the insulation shell 200. It is understood that the outlet and inlet of the refrigerant pipes are respectively connected to the refrigeration assembly 300, thereby forming a refrigerant circulation loop for the flow of refrigerant. In this embodiment, the bent and extended refrigerant pipes cover the outer wall of the insulation shell 200. It is understood that this bent and extended arrangement increases the contact area between the refrigerant pipes and the surrounding environment, thereby improving heat exchange efficiency, achieving rapid cooling, and further improving the uniformity of temperature distribution and the cooling effect within the refrigeration cavity 120.

[0048] Reference Figure 2 , Figure 3 and Figure 5As shown in this embodiment of the present invention, a first heat insulation plate 510 is provided on the side of the first evaporator 410 facing away from the heat insulation shell 200, and a second heat insulation plate 520 is provided on the side of the second evaporator 420 facing away from the heat insulation shell 200. The first heat insulation plate 510 and the second heat insulation plate 520 are connected to each other. Specifically, the first heat insulation plate 510 is spaced apart from the heat insulation shell 200, the first evaporator 410 is located between the first heat insulation plate 510 and the heat insulation shell 200, the first heat insulation plate 510 covers the first evaporator 410 and is fixedly connected to the vehicle body 100; the second heat insulation plate 520 is spaced apart from the heat insulation shell 200, the second evaporator 420 is located between the second heat insulation plate 520 and the heat insulation shell 200, the second heat insulation plate 520 covers the second evaporator 420 and is fixedly connected to the vehicle body 100. It is understood that in this embodiment, the outer sides of the bottom and top walls of the insulation shell 200 are provided with second heat insulation plates 520, and the adjacent first heat insulation plates 510 and second heat insulation plates 520 are connected to each other, thereby covering the outer wall of the insulation shell 200.

[0049] In this embodiment, the first heat insulation plate 510 and the second heat insulation plate 520 have a heat insulation function. In one example, the first heat insulation plate 510 and the second heat insulation plate 520 are made of aluminum plates with heat insulation function. Based on this, the first heat insulation plate 510 and the second heat insulation plate 520 can reduce the possibility of heat from the surrounding environment entering the interior of the vehicle body 100, thereby improving the cooling capacity of the evaporation assembly 400. At the same time, they further enhance the heat insulation capacity of the insulation shell 200, reduce the heat exchange between the refrigeration cavity 120 and the external environment, thereby improving the reliability of the refrigerated trolley 1000.

[0050] Reference Figure 2 and Figure 3 As shown in the embodiment of this utility model, the refrigerated trolley 1000 further includes a heat insulation layer (not shown in the figure). The heat insulation layer is disposed between the heat insulation shell 200 and the first heat insulation plate 510 and between the heat insulation shell 200 and the second heat insulation plate 520. The heat insulation layer is made of polyurethane foam. It can be understood that the polyurethane foam covers the side of the first heat insulation plate 510 and the second heat insulation plate 520 facing the heat insulation shell 200. The polyurethane foam has a heat insulation function, thereby reducing the heat exchange between the evaporation component 400 and the external environment, and thus improving the heat insulation capacity of the heat insulation shell 200. In one example, the heat insulation shell 200 is made of aluminum plate.

[0051] Reference Figure 2 and Figure 5As shown in this embodiment of the invention, the refrigerated trolley 1000 further includes multiple side panels 140, which are connected to the vehicle body 100 to form an inner cavity 150. An insulation shell 200 is installed within the inner cavity 150. Specifically, the multiple side panels 140 are arranged around the vehicle body 100 and fixedly connected to it. The multiple side panels 140 form the inner cavity 150, which can accommodate the insulation shell 200. In this embodiment, the connection between the side panels 140 and the vehicle body 100 can be achieved through fasteners or other connection methods such as snap-fit ​​connections; this embodiment does not limit the specific connection method.

[0052] Reference Figure 2 and Figure 5 As shown, in this embodiment, the side panel 140 is provided with mounting holes 141. Specifically, along the width direction of the refrigerated trolley 1000, the side panels 140 on both sides of the vehicle body 100 are provided with mounting holes 141. The mounting holes 141 penetrate the side panel 140 along the width direction of the refrigerated trolley 1000, and connect to the mounting cavity 110, and are located on one side of the mounting cavity 110. In this embodiment, a heat dissipation plate 600 is provided at the mounting hole 141. The heat dissipation plate 600 is detachably connected to the side panel 140. Specifically, the heat dissipation plate 600 covers the mounting hole 141. In this embodiment, the heat dissipation plate 600 and the side panel 140 can be connected by fasteners, or by other detachable connection methods such as snap-fit ​​connections. This embodiment does not limit this connection.

[0053] Reference Figure 2 and Figure 5 As shown, in this embodiment, the heat sink 600 is provided with a plurality of heat dissipation holes 610 spaced apart. The heat dissipation holes 610 are connected to the mounting cavity 110. Specifically, the plurality of heat dissipation holes 610 are evenly arranged on the heat sink 600. The heat dissipation holes 610 penetrate the heat sink 600 along the width direction of the refrigerated trolley 1000. The heat dissipation holes 610 connect the mounting cavity 110 with the external environment. It can be understood that the heat dissipated by the refrigeration component 300 during operation can be transferred to the external environment through the heat dissipation holes 610, thereby improving the stability of the operation of the refrigeration component 300.

[0054] Reference Figure 2 and Figure 5 As shown, in this embodiment, the projection of the mounting cavity 110 and the projection of the refrigeration cavity 120 are spaced apart on the projection surface along the width direction of the refrigerated trolley 1000. It can be understood that the heat emitted by the refrigeration component 300 during operation will be directly transferred to the external environment through the heat dissipation hole 610, reducing the possibility of heat transfer to the vicinity of the refrigeration cavity 120, thereby reducing the impact on the refrigeration cavity 120 and further improving the reliability of the refrigerated trolley 1000.

[0055] Reference Figure 3 , Figure 4 and Figure 6 As shown, in this embodiment of the present invention, the first evaporator 410 is disposed on both sides of the insulation shell 200 along the width direction of the refrigerated trolley 1000, and the insulation shell 200 is provided with openings 210 on both sides along the length direction of the refrigerated trolley 1000. The openings 210 connect to the refrigerated cavity 120. Specifically, the side wall on which the first evaporator 410 is installed avoids the side wall where the openings 210 are located, thereby ensuring the rationality of the structure of the refrigerated trolley 1000. The openings 210 are located on two side walls of the insulation shell 200 facing away from each other along the length direction of the refrigerated trolley 1000. It can be understood that the openings 210 can connect the refrigerated cavity 120 and the external environment.

[0056] Reference Figure 1 , Figure 2 and Figure 3 As shown, in this embodiment, the vehicle body 100 includes a door 130, which covers the opening 210 and is rotatably connected to the vehicle body 100. It is understood that the door 130 is located on the side of the opening 210 facing away from the refrigeration chamber 120, and the door 130 can move relative to the opening 210 to close and open the opening 210. In this embodiment, the door 130 and the vehicle body 100 can be connected by a hinge, or by other movable connection methods such as a snap-fit ​​connection; this embodiment does not limit this connection.

[0057] Reference Figure 2 , Figure 3 and Figure 5 As shown, in this embodiment, at least two insulation components 131 are provided on the inner side of the door 130. These at least two insulation components 131 are arranged sequentially along the length of the refrigerated trolley 1000 and connected to each other. Specifically, the at least two insulation components 131 overlap each other along the direction of the door 130 towards the vehicle body 100 and are installed inside the door 130. The insulation components 131 cover the side of the door 130 facing the opening 210 and are fixedly connected to the door 130. It is understood that in this embodiment, the insulation components 131 can be made of aluminum plates with heat insulation properties, or polyurethane foam, or other insulation materials; this embodiment does not limit this. Based on this, when the door 130 covers the opening 210, the insulation components 131 tightly cover the opening 210, reducing heat exchange between the refrigerated cavity 120 and the external environment, thereby improving the heat preservation capacity of the refrigerated cavity 120.

[0058] Understandably, the door 130 is installed on the outside of the vehicle body 100. On the one hand, this facilitates the rotational connection between the door 130 and the vehicle body 100. On the other hand, it facilitates the installation and removal of the insulation component 131, thereby improving the ease of installation of the door 130 and thus improving the assembly and disassembly efficiency of the refrigerated trolley 1000.

[0059] Reference Figure 4 , Figure 5and Figure 7 As shown in the embodiment of this utility model, the bottom of the heat insulation shell 200 is provided with a water collection component 700, the bottom wall of the heat insulation shell 200 is provided with a conical groove 231, the water collection component 700 is provided with a water gathering trough 710 with an opening 210 facing the conical groove 231, and the conical groove 231 is connected to the water gathering trough 710. Specifically, the bottom wall of the insulation shell 200 is a first insulation layer 230. The first insulation layer 230 is recessed in the opposite direction of the refrigeration cavity 120 to form a conical groove 231. A through hole 232 is provided in the center of the bottom wall of the conical groove 231. The through hole 232 penetrates the first insulation layer 230 along the line connecting the first insulation layer 230 and the refrigeration cavity 120. A water collecting component 700 is provided on the side wall of the first insulation layer 230 opposite to the refrigeration cavity 120 and is located directly below the through hole 232. The water collecting component 700 is recessed in the opposite direction of the through hole 232 to form a water collecting trough 710. The opening 210 of the water collecting component 700 faces the through hole 232.

[0060] Understandably, when the opening 210 is opened by the door 130, external heat will enter the refrigeration chamber 120 and form condensate. The condensate flows to the conical groove 231 at the bottom of the refrigeration chamber 120. The conical groove 231 allows the condensate to flow to the through hole 232. The condensate flows through the through hole 232 to the water collection tank 710, so that the condensate is discharged from the refrigeration chamber 120 in time, thereby reducing the impact of condensate on the refrigeration chamber 120 and improving the reliability of the refrigerated trolley 1000.

[0061] Reference Figure 2 , Figure 5 and Figure 7 As shown, in this embodiment, the second evaporator 420 is located at the bottom of the insulation shell 200 and is arranged around the water collection component 700. Specifically, the second evaporator 420 and the water collection component 700 are located between the second heat insulation plate 520 and the insulation shell 200. The second evaporator 420 is curved around the peripheral wall of the water collection component 700. It can be understood that the water collection component 700 and the second evaporator 420 are compactly installed at the bottom of the insulation shell 200, thereby improving the space utilization and structural design rationality of the refrigerated trolley 1000.

[0062] Reference Figure 1 , Figure 2 and Figure 5As shown in the embodiment of this utility model, the refrigerated trolley 1000 also includes a controller 800 and a sensor (not shown in the figure). The sensor is installed inside the insulation shell 200, and the controller 800 is installed on the side plate 140. The sensor is used to acquire the temperature inside the insulation shell 200. The controller 800 is connected to both the sensor and the refrigeration component 300. The controller 800 is configured to control the operation of the refrigeration component 300 according to the temperature detected by the sensor. It can be understood that, on the one hand, the controller 800 can control the operating state of the refrigeration component 300 according to the temperature set by the user, thereby controlling the temperature of the refrigeration cavity 120; on the other hand, the sensor can acquire the temperature signal inside the refrigeration cavity 120 at any time and transmit it to the controller 800. If there is a difference between the temperature signal and the temperature set by the user, the controller 800 will adjust the refrigeration operation state of the refrigeration component 300 on the insulation shell 200, thereby improving the accuracy of temperature control, improving the temperature stability of the refrigeration cavity 120, and thus improving the reliability of the refrigerated trolley 1000.

[0063] Reference Figure 1 , Figure 2 and Figure 5 As shown in this embodiment of the invention, the refrigerated trolley 1000 further includes a beverage dispensing device. The beverage dispensing device includes a pump assembly 900, multiple container bottles 910, multiple pipes (not shown in the figure), and a tap 920. The pump assembly 900 is installed in the mounting cavity 110. The multiple container bottles 910 are disposed within the refrigeration cavity 120. The tap 920 is installed on the top of the trolley body 100. The multiple container bottles 910 and multiple pipes are connected one-to-one. One end of each pipe is installed in a water tap, and the other end passes through the corresponding container bottle 910. The pump assembly 900 is configured to pump the beverage from the container bottle 910 to the tap 920. Specifically, multiple containers are placed at the bottom of the refrigeration cavity 120. One end of the tap 920 is connected to the external environment, and the other end is connected to the interior of the trolley body 100. The pipes are sequentially connected to the container bottles 910, the pump assembly 900, and the tap 920.

[0064] Understandably, beverage dispensing devices can integrate multiple beverages without interfering with each other during distribution, thus ensuring the unique taste of each drink. Furthermore, the dispensing device can quickly and accurately dispense drinks, thereby improving dispensing efficiency. Therefore, installing a beverage dispensing device on the refrigerated trolley 1000 not only maintains the beverages at a low temperature, reducing the possibility of contamination and improving freshness, but also enhances the usability of the refrigerated trolley 1000. Users can choose different flavors of beverages according to their personal preferences, thereby improving the user experience.
