The hot air circulation unit includes a heating member 31 and a blower 33. The blower 33 is disposed on the wall of at least one side of the accommodating chamber S, and the air sent by the blower 33 can flow circularly through the remaining walls of the accommodating chamber S along a direction parallel to the wall of the current chamber. The heating member 31 is provided on a wall of the accommodation chamber S where the blower 33 is not provided at least partially. In short, the heating element 31 and the blower 33 are respectively disposed on different wall surfaces in the accommodating chamber S, that is, the two are disposed separately, so as to avoid that the air sent by the blower 33 is directly heated at the air outlet end position where the air volume is concentrated, so that the heat is too concentrated to cause uneven heating.

When the serving trolley 100 is used by a user, the food is placed in the accommodating cavity S through the opening, and the heating member 31 and the blower 33 are turned on. When the air sent out by the air blower 33 parallel to the chamber wall where the air blower is located circularly flows through other chamber walls, the air is inevitably heated by the heating elements 31 arranged on the other chamber walls, and then hot air circulation is formed in the accommodating chamber S, the flowing hot air circulation does not directly blow to the meals, but the intensity of thermal convection in the accommodating chamber S is enhanced, so that the temperature distribution in the accommodating chamber S is more uniform, and the meals in the accommodating chamber S are further uniformly heated.

Further, the dining car 100 further includes a power cord 56, and an outer surface of the car body 10 is configured with a cord receiving cavity Q, and the power cord 56 can be received in the cord receiving cavity Q. The top of the dining car 100 is configured as a storage plane H for placing articles or temporarily placing meals, and two side plates 57 for preventing articles from falling are provided at both sides of the storage plane H. Wherein, still be connected with two pushing hands 58 between two breast boards 57, two pushing hands 58 are located the both ends of two breast boards 57 respectively, and two pushing hands 58 both have conveniently promoted the serving trolley 100 from two directions, also can prevent the article with breast board 57 together and drop.

Specifically, the dining car 100 further includes a plurality of heat insulation plates (not shown), which are respectively disposed at different positions of the accommodating cavity S and jointly wrap the accommodating cavity S. The heat insulation plate can effectively enhance the heat insulation performance of the serving trolley 100, and can also enable the residual heat of the heating element 31 to play a longer role when the serving trolley 100 is powered off.

In some embodiments, the blower 33 is disposed on the top wall of the receiving chamber S, and a wall of the receiving chamber S facing the air outlet end of the blower 33 is an air outlet sidewall C (as shown in fig. 5), and a wall of the receiving chamber S facing the air inlet end of the blower 33 is an air inlet sidewall J (as shown in fig. 5). Wherein, the heating member 31 is disposed on at least one of the bottom walls of the air-out sidewall C, the air-in sidewall J and the accommodating chamber S.

It is understood that the air blower 33 may be disposed on the bottom wall or the peripheral side wall, or the air blowers 33 may be disposed on the top wall, the bottom wall and the peripheral side wall respectively at positions where the heating members 31 are not mounted, so as to enhance the pushing action on the air in the accommodating cavity S, and the structure of the air blower may be adjusted adaptively, and the mounting position of the heating members 31 is not limited to the aforementioned positions. The installation of the blower 33 and the heating member 31 only needs to satisfy the following conditions: the blower 33 is separated from the installation position of the heating element 31; the blowing direction of the blower 33 is parallel to the wall surface of the installation position, and when the plurality of blowers 33 are respectively arranged in a plurality of areas of the top wall, the bottom wall and the peripheral side wall, the blowing wind of each blower 33 needs to be in the same clockwise direction so as to form the circulating wind.

In the case that the blower 33 is used less and occupies a smaller space, the blower 33 is mounted on the top wall to effectively push the hot air to move toward the bottom wall and mix with the air at the bottom wall, and the hot air flowing to the bottom wall can naturally move toward the top wall and mix with the air at the top wall under the effect of the lifting force, so that the temperature distribution in the accommodating chamber S can be balanced.

In the present embodiment, the heating members 31 and the air blowers 33 each include five heating members 31, five air blowers 33 are disposed on the bottom wall and the four peripheral side walls, respectively, and the five air blowers 33 are disposed side by side on the top wall, and the air blowing directions are parallel to each other. The plurality of heating members 31 can make heating more uniform and reduce heat concentration. The plurality of blowers 33 are more advantageous for achieving uniform blowing and ensuring sufficient wind power.

Referring to fig. 4 and 5, more specifically, the vehicle body 10 and the accommodating chamber S are rectangular, and the blower 33 blows air along the width direction of the accommodating chamber S. So set up the wind that on the one hand forced draught blower 33 produced and can reach air-out lateral wall C sooner and transmit along air-out lateral wall C, avoid leading to wind-force loss because of the removal of overlength distance, on the other hand forced draught blower 33 can set up along length direction, possess many and can set up the machine position. In addition, the position of the blower 33 is kept at a certain distance from both the air outlet side wall C and the air inlet side wall J, so that the blower 33 can smoothly supply air and discharge air.

In some embodiments, the heated air circulation assembly further includes an air duct plate 35, the air duct plate 35 being disposed in parallel and spaced relation to the top wall, and the blower 33 being disposed between the air duct plate 35 and the top wall. The air duct plate 35 and the top wall jointly form an air duct cavity W, and two ends of the air duct plate 35 respectively form an air outlet and an air inlet with the air outlet side wall C and the air inlet side wall J at intervals. The air duct plate 35 prevents the air generated by the blower 33 from blowing toward the food, and the air duct chamber W formed by the ceiling wall effectively guides the air flowing out from the air outlet and flowing in from the air inlet.

Further, the air duct plate 35 is configured with a water collection groove (not shown) for collecting condensed water generated by condensation of water vapor. When food is actually placed in the accommodating cavity S, water vapor is inevitably generated and guided by airflow and flows into the air duct cavity W in a large quantity, so that the water collecting grooves arranged on the air duct plate 35 can effectively collect water condensed in the air duct cavity W, and the phenomenon that the water flows to other places uncontrollably or even flows into the food to affect the taste and the flavor of the food is avoided.

Furthermore, the hot air circulation assembly further includes at least one guide plate 37, one end of each guide plate 37 is disposed on the wall of the cavity where the blower 33 is currently located, the other end of each guide plate 37 is disposed on the air outlet side wall C or the air inlet side wall J, and the surface of each guide plate 37 facing the accommodating cavity S is an arc-shaped guide surface. The guide plate 37 can effectively guide and change the direction of wind, and reduce wind loss.

In some embodiments, the dining car 100 further includes a plurality of horizontal supporting plates 71, and the horizontal supporting plates 71 are disposed in parallel in the accommodating cavity S and located at different heights relative to the bottom wall of the accommodating cavity S. Two ends of each horizontal supporting plate 71 are respectively spaced from the air outlet side wall C and the air inlet side wall J to form an air inlet P. The horizontal supporting plates 71 are used for placing food, the horizontal supporting plates 71 with different heights are convenient for placing more and more food orderly, and the air passing openings P are formed at the two ends of the horizontal supporting plates to avoid obstructing the air flow of the accommodating cavity S to influence the soaking effect.

Further, each horizontal supporting plate 71 is provided with a plurality of vent holes K (as shown in fig. 6). The ventilation holes K are also used for increasing the air flow passage in the accommodating cavity S, enhancing the heat convection between the accommodating cavity S and also for uniformly heating the meal on the horizontal supporting plates 71 by the hot air flowing between the different horizontal supporting plates 71.

When the serving trolley 100 is used by a user, the magnetic suction sealing door 11 is opened, food is placed on different horizontal supporting plates 71, then the magnetic suction sealing door 11 is closed, and the heating element 31 and the blower 33 can be started when heating is needed. The air generated by the blower 33 flows along the air duct cavity W, is guided by the guide plate 37 to change the direction, flows out from the air outlet, flows along the air outlet side wall C and the bottom wall successively, and is heated by the heating members 31 on the air outlet side wall C and the bottom wall. Meanwhile, the air at the air inlet side wall J is also heated by the heating element 31 and flows into the air duct chamber W under the action of the blower 33 through the air inlet along the air inlet side wall J under the guidance of the guide plate 37, thus forming a complete hot air circulation. The air in the accommodating cavity S strengthens the heat convection intensity under the action of the heated air circulation, and continuously flows between different horizontal supporting plates 71 through the air passing opening P and the vent holes K to uniformly heat the meals on the horizontal supporting plates 71. In addition, the vapor that the meal produced follows hot circulation wind and gets into in wind channel chamber W, and the comdenstion water that its produced can be effectively collected by the water catch bowl, avoids flowing to in the meal, influence taste and taste.

All possible combinations of the technical features of the above embodiments may not be described for the sake of brevity, but should be considered as within the scope of the present disclosure as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
