Description

Steam box

Technical Field

The invention belongs to the field of household appliances, and particularly relates to a steam box.

Background

In modern life, a steamer or a steam box is often used for steaming food. When a user uses the steamer to cook food, the user often difficultly grasps the required water consumption and operates the food completely by depending on experience, too little water is easy to be dried, and too much water causes the waste of water and heating energy.

Compared with the original steamer, the steam box has the advantages of controllable heating time and temperature, no dry burning and the like. However, the existing steam box is often insufficient in steam quantity when cooking food, so that the food cooking speed is slow, and the cooking effect is not good as that of a steamer. For example, in the process of cooking green vegetables, the steam volume of the steamer is large, so that the green vegetables can be quickly cooked and the fresh green color can be kept; however, the steam quantity of the steam box is small, so that the color of the green vegetables turns yellow when the green vegetables are steamed. For another example, when steaming fish, the steamer can quickly steam the fish with large steam and keep the fish fresh and tender, and the steaming speed of the steamer is relatively slow due to small steam amount, so that the nutrition of the fish is lost, and the taste of the fish is poor.

Meanwhile, the existing steam box usually adopts a steam generating device, but the working principle of the steam box is to generate superheated steam, the temperature of an air jet is usually higher than 100 ℃, although the temperature in the steam box can reach 100 ℃ quickly, the actual cooking environment generated by the superheated steam is not saturated steam, and the food heating speed is slower than that of a steamer.

Aiming at the problems that the existing steam box is low in steam quantity and unsaturated steam, so that the food cooking is slow and the cooking effect is poor, the invention provides the steam box which comprises a hot water generating device 1, a steam generating device 2 and a controller as shown in figure 1. Wherein the hot water generating device 1 is used for generating boiling water; the steam generating device 2 is arranged in a steam cavity 3 of the steam box and receives the boiling water generated by the hot water generating device 1, and the steam generating device 2 heats the boiling water to continuously generate saturated steam; the controller controls the amount of boiling water introduced into the steam generating device 2 by the hot water generating device 1.

It can be seen that the steam box of the present invention is particularly additionally provided with the hot water generating device 3, and quantitative boiling water (i.e. hot water of 100 ℃) is input into the steam generating device 2 through the hot water generating device 1, so that the steam generating device 2 realizes the effect of saturated cooking of food. In the steam box, the steam generating device 2 can simulate the effect of an original saturated steamer to directly heat boiling water, steam can be quickly discharged to ensure large air quantity, the generated steam is saturated steam rather than supersaturated steam, meanwhile, the hot water generating device 1 can be controlled by the controller to realize precise water supply, and the effects of saving energy consumption and water are realized, so that the satisfaction degree of users is improved.

Wherein the steam generating device 2 comprises a boiling water chamber for receiving boiling water and a boiling water heating plate 21 for heating the boiling water chamber. Therefore, compared to the conventional steam box which sprays water onto the heat generating plate, the steam generating device 2 of the present invention has a cavity in which boiling water is received, and can generate sufficient saturated steam, not superheated unsaturated gas, by heating the boiling water, thereby cooking food more effectively.

Meanwhile, in order to ensure controllability of the heating time of the boiling water, the steam generating device 2 further includes a timer for controlling the heating time of the boiling water heating pan 21 at regular time.

Particularly, the steam box is additionally provided with a hot water generating device, the hot water generating device 1 comprises a water storage cavity and a water storage heating plate for heating water in the water storage cavity into boiling water, the water storage cavity is provided with a water temperature sensor, and a flow control valve is arranged in a boiling water flow passage between the water storage cavity and the boiling water cavity. The water temperature sensor is adopted to sense and control the water boiling temperature in real time, and the controller is used to control the flow control valve so as to realize the quantitative supply of boiling water for the steam generating device 2.

Wherein, the hot water generating device 1 can be in a form of integrating a water dispenser arranged outside the steam box, and can also be an internal hot water generating device. Specifically, the steam box comprises a steam box unit and a drinking water unit, the steam generating device 2 is arranged in the steam box unit, and the hot water generating device 1 is arranged in the drinking water unit.

In the steam box of the present invention, to improve the experience for use, the controller is configured to: the corresponding heating time T and heating power B of the steam generating device 2 are selected according to the type of the cooking food material. The steam box can be selected in various ways, wherein the heating power B of the steam generating device 2 is mainly used for controlling the steam quantity of the steam box, and the higher the power is, the larger the steam quantity in a unit space is; the corresponding heating time T is the cooking time of the food cooked at the corresponding heating power B. Thus, the user can empirically select the desired heating power B and heating time T to cook the desired food effect.

The controller is further configured to: calculating the required boiling water amount; wherein, the boiling water amount calculation formula is as follows:

B*A*60＝2260*C(1)

wherein A is the heating efficiency of the steam generating device 2, B is the heating power of the steam generating device 2, C is the theoretical steam conversion per minute of boiling water to saturated steam at the heating power B, and 2260J/g is the heat of vaporization of water. In the boiling water amount calculation formula (1), the theoretical steam reforming amount per minute C for converting boiling water into saturated steam at the heating power B can be determined as long as a value of the heating power B is given, and thus, when the user selects the heating time T for which the user wants to cook, the amount of boiling water required for cooking can be determined to be C x T.

In order to prevent the dry-heating phenomenon in the steam generating device 2, a certain amount of dry-heating preventing water D is additionally added, so the amount of boiling water required for cooking food is preferably T C + D, the saturated steam amount can be ensured under the condition of not wasting heating energy, and the dry-heating phenomenon can not occur.

Specifically, in the steam box of the present invention, after the user selects the cooking heating power B (i.e., selects the steam amount) and the cooking heating time T (i.e., selects the tenderness of the cooking effect) according to the actual cooking requirement, the controller calculates the total amount of boiling water T C + D according to the formula (1) and the dry-boiling-preventing amount of boiling water in the preset program, and controls the hot water generating device 1 to supply the steam generating device 1 with the amount of boiling water T C + D. Wherein, the steam generating device 2 directly heats boiling water to ensure the purpose of quickly discharging saturated steam, and simultaneously, the effect of precise water supply is achieved due to the control of the controller. Correspondingly, the flow control valve is arranged in the hot water generating device 1 to control the water supply quantity, and the timer is arranged in the steam generating device 2 to control the heating time T, so that the steam box can finally achieve the effects of precisely controlling the quick steam discharge and saving water and energy.

Wherein, according to the actual size of the cavity inside the steam box, namely the size of the boiling water cavity of the steam generating device 2, the controller is configured as follows:

when the rated volume of the boiling water cavity of the steam generating device 2 is smaller than the required boiling water amount, controlling the hot water generating device 1 to introduce C + D/T grams of boiling water per minute into the steam generating device 2.

Or when the rated volume of the boiling water cavity of the steam generating device 2 is not less than the required boiling water volume, controlling the hot water generating device 1 to introduce C T + D g of boiling water into the steam generating device 2 at one time.

The small heating power gear, the medium heating power gear and the large heating power gear respectively correspond to the small steam quantity, the medium steam quantity and the large steam quantity of the steam box for cooking. Wherein, the cooking with small amount of steam is suitable for steaming food such as eggs and the like which need to keep the shape and keep tender and smooth; the medium steam amount is suitable for cooking foods such as rice and spareribs which are suitable for long-time cooking; the large steam amount is suitable for food such as fish which needs to be quickly steamed, and the user can judge the required actual gear and the cooking time according to actual experience.
